Graphite oxide sheet, now referred to as graphene oxide (GO), is the product of chemical oxidation and exfoliation of graphite powders that was first synthesized over a century ago. Interest in this old material has resurged in recent years, especially after the discovery of graphene, as GO is considered a promising precursor for the bulk production of graphene-based materials. GO sheets are single atomic layers that can readily extend up to tens of microns in lateral dimension. Therefore, their structure bridges the typical length scales of both chemistry and materials science. GO can be viewed as an unconventional type of soft material as it carries the characteristics of polymers, colloids, membranes, and as highlighted in this review, amphiphiles. GO has long been considered hydrophilic due to its excellent water dispersity, however, our recent work revealed that GO sheets are actually amphiphilic with an edge-to-center distribution of hydrophilic and hydrophobic domains. Thus, GO can adhere to interfaces and lower interfacial energy, acting as surfactant. This new property insight helps to better understand GO’s solution properties which can inspire novel material assembly and processing methods such as for fabricating thin films with controllable microstructures and separating GO sheets of different sizes. In addition, GO can be used as a surfactant sheet to emulsify organic solvents with water and disperse insoluble materials such as graphite and carbon nanotubes (CNTs) in water, which opens up opportunities for creating functional hybrid materials of graphene and other π-conjugated systems.

AbstractThe soft X-ray images taken by the Yohkoh Soft X-ray Telescope (SXT) provide a powerful new tool to solve the mechanism of solar flares. In particular, a limb flare that occurred on 1991, December 2 gives us convincing evidence that magnetic reconnection of a neutral sheet formed at the loop top participates in the flare energy release. The neutral sheet appears to be associated with a destabilized rising loop system (filament) sheared with respect to the flaring loop. Similar formations of X-ray arcades are seen in the quiet Sun associated with filament eruptions on much larger spatial dimension and with a much smaller energy scale.

Soft-bodied locomotion in fluid-filled confined spaces is critical for future wireless medical robots operating inside vessels, tubes, channels, and cavities of the human body, which are filled with stagnant or flowing biological fluids. However, the active soft-bodied locomotion is challenging to achieve when the robot size is comparable with the cross-sectional dimension of these confined spaces. Here, we propose various control and performance enhancement strategies to let the sheet-shaped soft millirobots achieve multimodal locomotion, including rolling, undulatory crawling, undulatory swimming, and helical surface crawling depending on different fluid-filled confined environments. With these locomotion modes, the sheet-shaped soft robot can navigate through straight or bent gaps with varying sizes, tortuous channels, and tubes with a flowing fluid inside. Such soft robot design along with its control and performance enhancement strategies are promising to be applied in future wireless soft medical robots inside various fluid-filled tight regions of the human body.

In a previous work1 we have studied the propagation of relativistic particles in the bulk for some of the most popular brane models. Constraints have been put on the parameter space of these models by calculating the time delay due to propagation in the bulk of particles created during the interaction of Ultra High Energy Cosmic Rays (UHECRs) with protons in the terrestrial atmosphere. The question was, however, raised that probability of hard processes in which bulk modes can be produced is small and consequently, the tiny flux of UHECRs cannot constrain brane models. Here we use Color Glass Condensate (CGC) model to show that effects of extra dimensions are visible not only in hard processes when the incoming photon/parton hits a massive Kaluza–Klein mode but also through the modification of soft/semi-hard parton distribution. At classical level, for an observer in the CM frame of UHECR and atmospheric hadrons, color charge sources are contracted to a thin sheet with a width inversely proportional to the energy of the ultra energetic cosmic ray hadron and consequently they can see an extra dimension with comparable size. Due to QCD interaction, a short life swarm of partons is produced in front of the sheet and its partons can penetrate to the extra-dimension bulk. This reduces the effective density of partons on the brane or in a classical view creates a delay in the arrival of the most energetic particles if they are reflected back due to the warping of the bulk. In CGC approximation the density of swarm at different distances from the classical sheet can be related and therefore it is possible (at least formally) to determine the relative fraction of partons in the bulk and on the brane at different scales. Results of this work are also relevant to the test of brane models in hadron colliders like LHC.

Abstract Electric field induced in magnetic reconnection is an efficient mechanism for generating energetic particles, but the detailed role it plays is still an open question in solar flares. In this work, accelerations of particles in an evolving reconnecting current sheet are investigated via the test-particle approach, and the electromagnetic field is taken in a self-consistent fashion from a 2.5D numerical experiment for the magnetic reconnection process in the corona. The plasma instabilities like the tearing mode in the current sheet produce magnetic islands in the sheet, and island merging occurs as well. For the motion of the magnetic island, it yields the occurrence of the opposite electric field at both endpoints of the island; hence, tracking the accelerated particles around magnetic islands suggests that the parallel acceleration does not apparently impact the energy gain of particles, but the perpendicular acceleration does. Furthermore, our results indicate that the impact of the guide field on the trajectory of accelerated particles in a more realistic electromagnetic configuration works only on those particles that are energetic enough. The energy spectra of both species show a single power-law shape. The higher-energy component of the power-law spectrum results from the particles that are trapped in the current sheet, while the escaped and partly trapped particles contribute to the lower-energy component of the spectrum. The evolution of the spectrum shows a soft-hard-soft pattern that has been observed in flares.

This research focus on improving the weaknesses of soft clay soils by using proper recycled material as a stabilization agent for strengthening purpose. Therefore, Diaper’s Back Sheet Layer Wastes (DBSLW) were used as the agent of soil stabilization. In this study, series of laboratory test were conducted to evaluate the optimum size and content of DBSLW as a strip reinforcement to increase the strength of Batu Pahat Soft Clay (BPSC). Testing program involves obtaining the physical properties of BPSC followed by California Bearing Ratio (CBR) test to determine the strength of BPSC with and without the addition of DBSLW. Result shows that the optimum size for DBSLW is 10 mm x 30 mm while the optimum content is 0.5%. At 15 mm penetration, sample with diapers strip of 10 mm x 30 mm dimension record 4.10 kN CBR value compare to 1.64 kN CBR value of untreated soil, 2.5 times stronger than untreated soil. Results of CBR tests demonstrated that inclusion of DBSLW strips in soil with optimum amounts and size improved strength and deformation behavior of soils substantially. The proposed technique could be used to advantage in road construction, industrial yards, and building structure.

This study aims to analyze the deflection behavior of the sheet pile through experimental testing and numerical analysis using the Finite Element Method (FEM). The Laboratorium scale test on a Tub with length of 1500 mm, width of 600 mm, and height of 1500 mm, and Steel Plate 3.2 mm with dimensions of 1400 mm x 590 mm was used as a model of the sheet pile wall. The subgrade material is clay soil and embankment material in the form of Sirtu which passes the No. sieve. 40. Physical and mechanical testing of soil and gravel materials is carried out with reference to ASTM standards. The measurement of the value of the strip load (q) and deflection was carried out using a load cell with a capacity of 100 kN and a linear variable differential transformer (LVDT). The deflection of the sheet pile was using was analyzed using Plaxis 8.2 software of the FEM method. The results of laboratory tests show that the pile wall collapses at a load of 74 kN/m2, with a deflection of 24.56 mm, while the FEM analysis shows that the pile wall collapses at a load of 71 kN/m2 with a deflection of 21.29 mm.

The processes of ignition and formation of soot precursor and soot particles in a diesel spray flame achieved in a rapid compression machine (RCM) were imaged two-dimensionally using the laser sheet techniques. For the two-dimensional imaging of time and of location where ignition first occurs in a diesel spray, planar laser-induced fluorescence (PLIF) of formaldehyde was applied to a diesel spray in an RCM. Formaldehyde has been hypothesized to be one of the stable intermediate species marking the start of oxidation reactions in a transient spray under compression ignition conditions. In this study, the laser-induced fluorescence (LIF) images of the formaldehyde formed in a diesel fuel spray during the ignition process have been obtained by exciting formaldehyde with the third harmonic of a neodymium-doped yttrium aluminium garnet (Nd:YAG) laser. The LIF images of formaldehyde in a spray revealed that the time when the first fluorescence is detected is almost identical with the time when the total heat release due to low-temperature oxidation reactions equals the heat absorption by fuel vaporization in the spray. The formaldehyde level rose steadily until the high-temperature reaction phase of diesel spray ignition. At the start of this ‘hot-ignition’ phase, the formaldehyde concentration fell rapidly, thus signalling the end of the low-temperature ignition phase. Increases in the initial ambient gas temperatures advanced the hot-ignition starting time. The first hot ignition occurred in the periphery of spray head at initial ambient gas temperatures between 580 and 660 K. When the ambient gas temperature was increased to 790 K, the position of the first ignition moved to the central region of the spray head. For the investigation of soot formation processes in a diesel spray flame, simultaneous imaging of the soot precursor and soot particles in a transient spray flame in an RCM was conducted by PLIF and by planar laser-induced incandescence (PLII) techniques. The third harmonic (355 nm) and the fundamental (1064 nm) laser pulses from an Nd:YAG laser, between which a delay of 44 ns was imposed by 13.3 m of optical path difference, were used to excite LIF from the soot precursor and laser-induced incandescence (LII) from soot particles in the spray flame. The LIF and the LII were separately imaged by two image-intensified charge-coupled device cameras with identical detection wavelengths of 400 nm and bandwidths of 80 nm. The LIF from the soot precursor was mainly located in the central region of the spray flame between 40 and 55 mm (between 270 and 370 times the nozzle orifice diameter d°) from the nozzle orifice. The LII from soot particles was observed to surround the soot precursor LIF region and to extend downstream. The first appearance of the LIF from the soot precursor in the spray flame preceded the appearance of the LII from soot particles. The intensity of the LIF from the soot precursor reached its maximum immediately after rich premixed combustion. In contrast, the intensity of the LII from soot particles increased gradually and reached its maximum after the end of injection. Measured LIF spectra, of the soot precursor in the spray flame, were very broad with the peak between 430 and 460 nm.

Between the 13th and 19th day of pregnancy the sheep conceptus developed into a structure showing considerable differentiation and all the extraembryonic membranes were established. Both length and dried weight of the embryo increased exponentially during this period. A highly significant regression of dried weight on length of embryos was found but measurement of the additional variable, width, did not improve the accuracy of estimating weight from the embryo's dimensions. The mass of the extraembryonic membranes also increased greatly. The dried weight of the trophoblast increased 90-fold over this period; that of the yolk sac increased 17-fold from day 15 to day 19. The protein content of each of the structures making up the sheep conceptus approached 50% of dried weight, which is similar to the proportion in adult soft tissues. The contribution of glycogen to dried weight was low in the sheep embryo and embryonic membranes when compared with estimates in the mouse blastocyst. However, at about the time of implantation the level of this polymer in the embryo was high compared with that in adult soft tissues and approached the level found in adult muscle. Concentrations of DNA and RNA in the sheep conceptus are much higher than the levels in most adult soft tissues and probably reflect higher synthetic rates and a smaller cytoplasmic volume in the embryonic cells.

Different sound atmosphere effects were investigated on SnO2:Sb thin films, which were deposited with dip coating technique. Two sound atmospheres were used in this study; one of them was nay sound atmosphere for soft sound, another was metallic sound for hard sound. X-ray diffraction (XRD) graphs have indicated that the films have different orientations and structural parameters in quiet room, metallic and soft sound atmospheres. It could be seen from UV–Vis spectrometer measurements that films have different band gaps and optical transmittances with changing sound atmospheres. Scanning electron microscope (SEM) and AFM images of the films have been pointed out that surfaces of films have been affected with changing sound atmospheres. The electrical measurements have shown that films have different I–V plots and different sheet resistances with changing sound atmospheres. These sound effects may be used to manage atoms in nano dimensions.

The trigonally trisubstituted carboxylic acid 3,5-dinitrobenzoic acid, (O2N)2C6H3COOH, forms 2:1 salts with a range of organic diamines L, with the general composition [LH2]2+·[{(O2N)2C6H3COO}−]2. When L is a bis-tertiary amine the hard N—H...O hydrogen bonds generate finite three-component aggregates, anion...cation...anion, and these aggregates are further linked by soft C—H...O hydrogen bonds to form one-dimensional molecular ladders when L is N,N,N′,N′′-tetramethyl-1,2-diaminoethane and chains of rings when L is 4,4′-dipyridylethane or 4,4′-dipyridylethene; two-dimensional sheets are formed when L is 1,4-diazabicyclo[2.2.2]octane and a three-dimensional framework is formed when L is N,N′-dimethylpiperazine. When L is the bis-secondary amine piperazine, the hard N—H...O and soft C—H...O hydrogen bonds each generate continuous motifs in the form of distinct chains of rings, the combination of which generates sheets, while when L is the bis-primary amine 1,2-diaminoethane the hard N—H...O hydrogen bonds alone generate a three-dimensional framework.

Clamping devices with constant force or pressure are desired in medical instruments, such as hemostatic forceps and the artificial sphincter, to prevent soft tissues from injures due to overloading. This paper studies the design method issues in constant force components using superelastic shape memory alloy. A generalized method for generating a constant force components-based shape memory alloy is proposed. An example of a C-shaped shape memory alloy sheet with a thickness of 0.2 mm is presented. The design results using the generalized design method for a C-shaped shape memory alloy sheet with 0.2 mm thickness are compared with its experimental results. Based on the generalized design method, the obtained design solutions for Cases 1 and 2 are coincident with the results obtained by the experiments. It could be seen that the generated design shape of the superelastic shape memory alloy component might obtain constant force within a relatively large deformation range. It is validated that the proposed generalized design method was feasible and effective. It is also illustrated that changing the geometric dimensions of the superelastic SMA component might obtain constant force within a relatively large deformation range.

In this article, bending behavior of the sandwich plates with embedded shape memory alloy wires in their face sheets is studied. Three-dimensional finite element method is used for constructing and analyzing the sandwich plates with flexible core and two stiff face sheets. Some important points such as continuity conditions of the displacements, satisfaction of inter-laminar transverse shear stresses, conditions of zero transverse shear stresses on the upper and lower surfaces and in-plane and transverse flexibility of the soft core are considered for the accurate modeling of the sandwich plate. Solutions for bending analysis of shape memory alloy wire-reinforced sandwich plates under various transverse loads are presented and the effects of plate dimensions, shape memory alloy wires diameter, boundary conditions and shape memory alloy wires embedding positions are studied. Comparison of the present results in special case with those of the three-dimensional theory of elasticity and some plate theories confirms the accuracy of the proposed model. According to the obtained numerical results, the local behavior of the sandwich plate in bending against various loading conditions was significantly improved by employing the shape memory alloy wires in the face sheets.

One of the wound treatments was negative pressure wound therapy (NPWT), which used wound dressings on the wound bed to ameliorate wound healing. Unfortunately, most wound dressings were two dimensional (2D), lacking the ability to cover severe wounds with a straightforward procedure. The sheets needed to be stacked following the wound curvature, which might be problematic since improper stacking could hinder the wound healing. Regarding the mentioned problems, our group develops 3D wound dressings, which are made using 3D printers. The wound dressings are made of polycaprolactone (PCL), polyurethane (PU), and polyvinyl alcohol (PVA). As the initial stage, the mechanical integrity of the soft polymers was investigated under uniaxial tensile and uniaxial compressive stress using computational methods. The polymers were defined as 3D lattices following the dimension of existing wound dressings. Based on the simulation results of displacement and von Mises stress, the three polymers are mechanically safe to be used as wound dressing materials.

Lameness is a major welfare problem in farm animals and poor hoof (claw) health frequently causes painful lesions. Such lesions frequently arise from damage to the underlying dermal and epidermal soft tissues causing impaired production of the horn on the external surface of the claw (Budras et al., 1998) Precisely timed interactions between embryonic dermis and epidermis, are essential for normal development and function in other integumental tissues such as the hair follicle (Galbraith, 1998), but have not been confirmed for claw tissue. The time course of development of cellular and extra-cellular structures has not been described, nor has the question of whether fetal prenatal claw development may be affected by undernutrition of the ewe such as frequently occurs in extensive production systems. The aims of the study were to investigate external physical dimensions and internal cellular development of fetal claws and how these may be influenced by stage of gestation and maternal nutrition.

Microscale sandwich beams with cell diameters and wall widths down to 150 and 15 μm, respectively, and having both metallic and polymer/metal cores were produced through fabrication methods that combined photolithography and electrodeposition. Various core structures were used, including some with negative Poisson's ratio. The bending response was investigated and compared with beam-theory predictions. Most of the cores evaluated had sufficient shear stiffness that the bending compliance was relatively high and dominated by the face sheets. Two of the core configurations were “soft” and exhibited behavior governed by core shear. The relative dimensions of the cores evaluated in this study were far from those that minimize the weight, because of fabrication constraints. The development of an ability to make high-aspect ratio cores is an essential next step toward producing structurally efficient, lightweight microscale beams and panels.

Soft tissues (e.g., tendon, skin, cartilage) change their dimensions and properties in response to applied mechanical stress/strain, which is called remodeling. Experimental studies using tissue cultures were performed to understand the biomechanical properties of collagen fascicles under mechanical loads. Collagen fascicles were dissected from sheep Achilles tendons and loaded under 1, 2, and 3 kg for 2, 4, and 6 days under culture. The mechanical properties of collagen fascicles after being loaded into the culture media were determined using tensile tester, and resultant stress–strain curves, tangent modulus, tensile strength, and strain at failure values were compared with those in a non-loaded and non-cultured control group of fascicles. The tangent modulus and tensile strength of the collagen fascicles increased with the increasing remodeling load after two days of culture. However, these values gradually decreased with the increasing culture period compared with the control group. According to the results obtained in this study, the mechanical properties of collagen fascicles were improved by loading at two days of culture, most likely due to the remodeling of collagen fibers. However, after a period of remodeling, local strains on the collagen fibrils increased, and finally, the collagen fibrils broke down, decreasing the mechanical properties of the tissue.

Quels sont les chemins pour durer dans un contexte d’incerti­tude sur les conditions du futur ? Les logiques d’action sur le long terme sur lesquelles les éleveurs s’appuient pour déve­lopper ou adapter leur ferme dans leur contexte propre ont été décrites. Ces logiques renvoient à des choix relatifs au dimensionnement de l’activité agricole, à la spécialisation, aux choix techniques et commerciaux, au rapport à l’endet­tement et à l’incorporation de technologies. Les données provenaient d’élevages ovins des Cévennes, région pastorale méditerranéenne du sud de la France, à partir de relevés de trajectoires d’évolution des familles, des activités agricoles et de la conduite du troupeau ovin sur 30 ans (1982–2012). Si l’élevage ovin n’a pas vraiment changé dans ses dimensions techniques pendant cette période, trois logiques d’action sur le long terme ont été distinguées : une logique clanique qui donne l’opportunité d’une installation des enfants dans la ferme ou à proximité d’elle ; une logique centrée sur l’activité ovine avec un agrandissement du troupeau ; et une logique multiphase avec l’exploration successive de deux ou trois formules de conduite du troupeau ou de combinaison d’ac­tivités du ménage. Les logiques d’action identifiées ont été semblables à celles décrites dans d’autres études, si ce n’est qu’elles n’ont pas mis en avant de logique fondée sur l’ac­croissement de la productivité du troupeau avec incorporation de technologies, option trop éloignée du type de pastoralisme pratiqué dans les Cévennes.

A multilayer piezoelectric material was fabricated using piezoelectric materials with low-temperature sintering capabilities and high piezoelectric coefficients to develop a functionally superior piezoelectric speaker with a large-displacement deformation. A soft relaxor was utilized to prepare the component materials, with the optimized composition of the investigated piezoelectric ceramics represented by 0.2Pb((Zn0.8Ni0.2)13Nb23)O3−0.8Pb(Zr0.5Ti0.5)O3. Li2CO3 was added to assist the low-temperature sintering conducted at 875 °C, which yielded a multilayer piezoelectric material with superior properties (d33 = 500 pC N−1, kp = 0.63, g33 = 44 mV N−1). A multilayer piezoelectric actuator with a single-layer thickness of ~40 µm and dimensions of 12 × 16 mm2 was fabricated by tape casting the prepared green sheets. Finite element analysis revealed that the use of a PEEK film and a smaller silicone–rubber film as a composite in the diaphragm realized optimal frequency-response characteristics; the vibrations generated by the piezoelectric element were amplified. The optimal structure obtained via simulations was applied to fabricate an actual piezoelectric speaker with dimensions of 20 × 24 × 1 mm3. The actual measurements exhibited a sound pressure level of ~75 dB and a total harmonic distortion ≤15% in the audible frequency range (250–20,000 Hz) at an applied voltage of 5 Vp.

Much of our understanding of the spatial organization of and interactions between cellular organelles and macromolecular complexes has been the result of imaging studies utilizing either light- or electron-based microscopic analyses. These classical approaches, while insightful, are nonetheless limited either by restrictions in resolution or by the sheer complexity of generating multidimensional data. Recent advances in the use and application of X-rays to acquire micro- and nanotomographic data sets offer an alternative methodology to visualize cellular architecture at the nanoscale. These new approaches allow for the subcellular analyses of unstained vitrified cells and three-dimensional localization of specific protein targets and have served as an essential tool in bridging light and electron correlative microscopy experiments. Here, we review the theory, instrumentation details, acquisition principles, and applications of both soft X-ray tomography and X-ray microscopy and how the use of these techniques offers a succinct means of analyzing three-dimensional cellular architecture. We discuss some of the recent work that has taken advantage of these approaches and detail how they have become integral in correlative microscopy workflows.

Convection in a compressible fiuid with an imposed vertical magnetic field is studied numerically in a three-dimensional Cartesian geometry with periodic lateral boundary conditions. Attention is restricted to the mildly nonlinear regime, with parameters chosen first so that convection at onset is steady, and then so that it is oscillatory.Steady convection occurs in the form of two-dimensional rolls when the magnetic field is weak. These rolls can become unstable to a mean horizontal shear flow, which in two dimensions leads to a pulsating wave in which the direction of the mean flow reverses. In three dimensions a new pattern is found in which the alignment of the rolls and the shear flow alternates.If the magnetic field is sufficiently strong, squares or hexagons are stable at the onset of convection. Both the squares and the hexagons have an asymmetrical topology, with upflow in plumes and downflow in sheets. For the squares this involves a resonance between rolls aligned with the box and rolls aligned digonally to the box. The preference for three-dimensional flow when the field is strong is a consequence of the compressibility of the layer- for Boussinesq magnetoconvection rolls are always preferred over squares at onset.In the regime where convection is oscillatory, the preferred planform for moderate fields is found to be alternating rolls - standing waves in both horizontal directions which are out of phase. For stronger fields, both alternating rolls and two-dimensional travelling rolls are stable. As the amplitude of convection is increased, either by dcereasing the magnetic field strength or by increasing the temperature contrast, the regular planform structure seen at onset is soon destroyed by secondary instabilities.

AbstractDual-phase steel shows a strong connection between its microstructure and its mechanical properties. This structure–property correlation is caused by the composition of the microstructure of a soft ferritic matrix with embedded hard martensite areas, leading to a simultaneous increase in strength and ductility. As a result, dual-phase steels are widely used especially for strength-relevant and energy-absorbing sheet metal structures. However, their use as heavy plate steel is also desirable. Therefore, a better understanding of the structure–property correlation is of great interest. Microstructure-based simulation is essential for a realistic simulation of the mechanical properties of dual-phase steel. This paper describes the entire process route of such a simulation, from the extraction of the microstructure by 3D tomography and the determination of the properties of the individual phases by nanoindentation, to the implementation of a simulation model and its validation by experiments. In addition to simulations based on real microstructures, simulations based on virtual microstructures are also of great importance. Thus, a model for the generation of virtual microstructures is presented, allowing for the same statistical properties as real microstructures. With the help of these structures and the aforementioned simulation model, it is then possible to predict the mechanical properties of a dual-phase steel, whose three-dimensional (3D) microstructure is not yet known with high accuracy. This will enable future investigations of new dual-phase steel microstructures within a virtual laboratory even before their production.

The structural elements of the secretory pathway in the budding yeast Saccharomyces cerevisiae were analyzed by 3D stereo-electron microscopy using relatively thick sections in which membranes were selectively impregnated. In a wild-type strain, tubular networks of various sizes and staining properties were distributed throughout the cytoplasm. As a rule, wide-meshed, lightly stained polygonal networks were connected to more or less fenestrated sheets of endoplasmic reticulum (ER). Some of these networks were continuous with more intensely stained networks and narrower meshes that displayed at their intersections nodular dilations that progressively increased in size and staining properties to reach those of secretion granules. Such networks presumably corresponded to Golgi elements. Indeed, stacked cisternae typical of the mammalian Golgi apparatus are rarely found in wild-type cells. However, if it is assumed that the Golgi apparatus plays a key role in the segregation and maturation of secretion granules, then tubular networks with nodular dilations should be equivalent to parts of this organelle. In correlation with the increase in size and density of the nodules there was a decrease in diameter and staining intensity of the interconnecting tubules. These results parallel observations on the formation of secretory granules in mammalian cells and suggest that the segregation of secretory material is concomitant with the progressive perforation and tubulization of previously unperforated sheets. When the sec21-3 thermosensitive mutant was examined at the nonpermissive temperature (37°C), the secretory pathway was blocked at exit from the ER, which started to accumulate as clusters of narrow, anastomosed, unperforated ribbon-like elements. When the block was released by shifting down to permissive temperature (24°C), tubular networks of various sizes and caliber, presumably Golgi in nature, formed as soon as 5 minutes after release of the block. At later time intervals, granules of various sizes and densities appeared to be released by rupture of these tubular networks or even to form at the edges of ER fenestrae. These observations support a dynamic maturation process in which the formation of secretion granules occurs by means of an oriented series of membrane transformations starting at the ER and culminating with the liberation of secretion granules from Golgi networks.

Bearings of small turbo machines support high speed rotors rotating with the frequency over 1 [kHz]. Such bearings are often supported with O-rings made of soft materials like rubber to attenuate high frequency oscillations. Dynamic properties of rubber supporters have been measured experimentally for individual dimensions, but the universal prediction of dynamic properties for various frequencies is difficult not only because rubbers exhibit nonlinearity against its strain, but because O-ring supporters deform heterogeneously. For the precise prediction, it is necessary to investigate the viscoelasticity of rubber under various deformations and frequencies. Such properties can be measured by the standard shear vibration non-response method of ISO 6721-6 (JIS K 7244-6). However this is applicable only to low frequency range under 100 [Hz] because of the limitation of resonance frequency of the load cell. In this research, based on BERM (Base Excitation Resonant Mass) method, a new method was developed to measure the complex shear modulus at high frequencies up to 1 [kHz] of rubber sheets under homogeneous shear deformations. In the presented method, the force is calculated from the acceleration of the mass instead of the direct measurement by a load cell. Hence accurate measurement became possible even in the range beyond the resonance frequency of a load cell. The measured shear storage modulus G’ and shear loss modulus G” of deformed rubber were presented.

We present the rapid-prototyping of type I collagen micropatterns on poly-dimethylsiloxane substrates for the biomimetic confinement of cells using the combination of a surface oxidation treatment and 3-aminopropyl triethoxysilane silanisation followed by glutaraldehyde crosslinking. The aim of surface treatment is to stabilise microcontact printing transfer of this natural extracellular matrix protein that usually wears out easily from poly-dimethylsiloxane, which is not suitable for biomimetic cell culture platforms and lab-on-chip applications. A low-cost CD-DVD laser was used to etch biomimetic micropatterns into acrylic sheets that were in turn replicated to poly-dimethylsiloxane slabs with the desired features. These stamps were finally inked with type I collagen for microcontact printing transfer on the culture substrates in a simple manner. Human hepatoma cells (HepG2) and rat primary hepatocytes, which do not adhere to bare poly-dimethylsiloxane, were successfully seeded and showed optimal adhesion and survival on simple protein micropatterns with a hepatic cord geometry in order to validate our technique. HepG2 cells also proliferated on the stamps. Soft and stiff poly-dimethylsiloxane layers were also tested to demonstrate that our cost-effective process is compatible with biomimetic organ-on-chip technology integrating tunable stiffness with a potential application to drug testing probes development where such cells are commonly used.

Soft computing was advocated by Prof. Zadeh as a total technology complementary to the advantages and disadvantages of fuzzy theory, neural network models, genetic algorithms, and so on - a wide variety of topics covered at scientific conferences, in books, in papers, etc. In human-centered information systems, human beings play a central role in information processing. Human information processing involves uncertainty, fuzziness, ambiguity, subjectivity, etc., be dealt with well by soft computing. Human-centered information processing systems are important fields of soft computing. This special issue was motivated by the editors' research project at the Tsukuba Advanced Research Alliance (TARA), University of Tsukuba. The title of this issue is thus similar to the TARA project title, Soft Computing and Human Centered Information Systems. This special issue comprehensively covers soft computing, including chaos theory, rough sets, multisets, as well as fuzzy theory, neural network models, and genetic algorithms. Human-centered information systems are also covered extensively, e.g., human imperfect information processing, human evaluation/judgment, optimal allocation problems, vehicle systems, and human intelligent information processing. This issue focuses on eight papers: The first, A Semantic-Ambiguity-Free Relational Model for Handling Imperfect Information, by Nakata, focuses on imperfect information without semantic ambiguity from the standpoint that an extension of relational models causes semantic ambiguity. This paper proposes an extended relational model in the framework of fuzzy sets and the theory of possibility. The paper formulates set and relational operations as extended relational algebra in the proposed model. The paper is applicable to human imperfect information processing. The second paper, Fuzzy Clustering for Detecting Linear Structures with Different Dimensions, by Umayahara et al., proposes a new objective function and an algorithm for detecting clusters with different dimensionalities. The proposed algorithm improves conventional approaches for detecting linear varieties with different dimensionalities. The paper also uses the noise cluster to deal with extraordinary data. The procedures of the proposed algorithm are demonstrated using numerical examples. The algorithm is useful for human evaluation data processing. As shown by Takahara et al., in An Adaptive Tabu Search and Other Metaheuristics for a Class of Optimal Allocation Problems, an adaptive tabu search for a class of optimal allocation problems uses a set of tables for objects as memory elements in which the search region becomes large, and the structure of memory and the search framework are simplified. This is applied to a class of optimal allocation problems in which small and irregular shapes are placed on a large sheet. The method's effectiveness is compared to results obtained by other metaheuristics. This method is useful for optimal allocation problems faced by human beings. The fourth paper, On Dynamic Clustering Models for 3-Way Data, by Sato, deals with 3-way data consisting of objects, attributes, and times using several clustering models. This paper focuses on the models for 3-way data observed by similarities of objects. The paper proposes models showing exact changes over time by fixing clusters during time. The model configuration is based on fuzzy additive clustering models. Models are modified based on data features. Numerical examples demonstrate that the proposed model shows the movements of objects over time. The fifth paper, A Fuzzy Linear Regression Analysis for Fuzzy Input-Output Data Using the Least Squares Method under Linear Constraints and Its Application to Fuzzy Rating Data, by Takemura, applies a fuzzy linear regression model to the analysis of fuzzy rating data. The paper considers a fuzzy linear regression model with fuzzy input data, fuzzy output data, and fuzzy parameters, since human rating data is usually fuzzy. The paper discusses fuzzy linear regression analysis using the least squares method under linear constraints. The present approach is rather heuristic in that it is an extension of the ordinary least squares method for crisp data. Fuzzy linear regression analysis is applied to psychological studies, i.e., the effect of perceived temperature and humidity on unpleasantness and behavioral intention in fashion shopping. This paper deals with human judgment, considering the human being as a human-centered system. The sixth paper, Study on Intelligent Vehicle Control Considering Driver Perception of Driving Environment, by Takahashi et al., discusses an approach of the design of an intelligent vehicle controller supporting driver vehicle use. The approach considers the interaction of the driving environment, vehicle behavior, and driver expectations of vehicle behavior. The paper uses a multiobjective decision-making model as the intelligent vehicle controller and a fuzzy measures and fuzzy integrals model to reflect driver characteristics. The simulation and experimental results show good vehicle control performance. A vehicle does not move without human control. In this sense, the paper deals with human-centered systems as such. The seventh paper, Determinism Measurement in Time Series by Chaotic Approach and Its Applications, by Fujimoto et al., discusses deterministic chaos. The proposed method, trajectory parallel measure (TPM), distinguishes chaos from embedded time series data. This is simpler than conventional methods and examines only the direction of tangential unit vectors of the trajectory in its neighborhood. This is applied to chaotic time series data with random noise. Fast Fourier transform (FFT) analysis is applied to data to verify the effectiveness of the proposed method. Although FFT analysis cannot distinguish the degree of random noise, the proposed TPM clearly distinguishes it. TPM is also applied to the diagnosis of automobile components. TPM detects abnormal acoustic time series data well. TPM is applicable to fault diagnosis of human-centered systems, e.g., vehicles. The final paper, Linguistic Expression Generation Model of Subjective Content in a Picture, by Iwata et al., proposes a model that expresses subjective contents in a picture given objective information on the picture. Objective information is information on object's location, size, direction, etc. Subjective content is emotions of a human object, the relationship between objects, and object behavior obtained from objective information. Human emotions are recognized from facial expressions using neural network models. Fuzzy reasoning is applied to infer the relationship between objects. Case-based reasoning is used to express object behavior. The effectiveness of the present model is verified by experiments. This paper deals with human intelligent information processing, considering the human being as a human-centered system. We thank Drs.

The Dark Web is its own clandestine network of thousands of websites that most of us do not even know exist, much less how to access. The Dark Web uses its own tools to keep users anonymous and their activities hidden. The Dark Web is so well concealed that the full extent of its use remains largely the topic of hushed conversations. From black market drug sales to child pornography, the Dark Web operates at two extremes of the Internet, from venues for anonymous whistleblowing on one end to unguarded censorship on the other. This article provides a primer for those interested in learning more about the “known unknowns” of the Dark Web. Readers will find an excellent opening manuscript for the newly launched International Journal of Cyber Research and Education as it sets the stage for future research in cyber security and law enforcement. The paper will examine three foundational questions for the reader: What constitutes the ‘deep/dark/underground' web and keeps it obscure and remote from the community of legitimate users? How can websites that occupy the same virtual space range exist in two parallel dimensions from discoverable to undiscoverable? And finally, how do the actors on the Dark Web mature from novice to advanced? Is it the same process followed by users of the known web? In the corpus of this article, the authors will briefly examine how online markets exist simultaneously on the Internet, serving clients in both known online environments as well as the more secretive, anonymous online world. They will examine how nefarious actors migrate from the “good” web to become novice and then advanced users of the “evil” environments. To the neophyte user, the process introduced herein may appear relatively straightforward. In truth, the notion that any but the most staunchly dedicated practitioner can become a vetted participant in the ‘dark web' is inconceivable. Even so, with the sheer volume of actors operating in numerous underground forums and marketplaces, the impact remains significant and growing geometrically. Government and industry from all over the globe are hindered in their ability to track and identify the truly advanced actors operating in these more secretive environments. We shall soon see why this is the case.

A magnificent casket in a woman’s grave from the Viking AgeIn 2004 and 2006, Moesgård Museum excavated 21 Viking Age graves – 16 inhumation graves and five cremation graves – at Haldum Church, 20 km northwest of Århus in Eastern Jutland (fig. 1). All the graves with datable finds are from the 10th century; only one example will be presented here.The grave is a simple inhumation burial. The skeleton had completely disappeared and there were no signs of a coffin (fig. 2). About 40 cm from the western end of the grave base lay 16 glass beads scattered around over an area of about 20 x 30 cm. These comprised one red and one orange bead of opaque glass, one bead of white glass and 13 small beads of yellow glass. In the centre of the grave was a slate whetstone (fig. 3). At the eastern end was a concentration of iron fittings, and it soon became clear that these represented the remains of a casket.During excavation of the fittings a well-preserved lock turned up (fig. 4). One end of the lock’s cover plate terminates in a point with concave flared sides, while the other (broad) end divides into two prongs, between which a transverse, semicircular fitting has rusted fast. An iron band has been mounted across the pointed end; this is possibly a repair. The cover plate curves slightly along its length, which means that the lock must have been fitted on to a curved surface. The back of the lock is covered by a quadrangular plate. The distance between front and back plates is 15 mm, showing the thickness of the material within which the lock was fitted. On removing the back plate the lock construction can be seen; this is of well-known Viking Age type. It operates in such a way that the key – after having been placed into the keyhole – is pushed a little to the side so that it squeezes together the two springs of the bolt. The bolt is hereby disengaged and can be pulled back by means of a slide bar, which sits in continuation of the keyhole (fig. 5).The lock bolt is pushed into the above-mentioned, semicircular fitting. The latter comprises two plates separated by a c. 10 mm wide side piece, which gives the fitting the appearance of a small box. Three fittings of this type were found (fig. 6).Further to these components are edge and corner plates. The edge fittings all have the form of narrow, indented borders with small holes between the points. A fragment is shown lowermost on fig. 6. The corner plates have been bent back around the corner joints of the casket and are pointed at both sides.Certain other fittings were at first inexplicable. These mysterious pieces include three triangular fittings with small slide bars on their upper surface and 30 mm long bolts below (fig. 7). There are also fragments of some zip-like iron bands. These are slightly curved along their length and have a roof-shaped cross-section (fig. 8). Finally, there was a robust rivet with a square head, ingeniously worked with inwardly flared, tapered sides and crowned by a small boss.Wood imprints on the back of the fittings show that the casket was made of oak. The imprints were very useful when reconstructing the casket as they clearly show both the longitudinal direction of the wood and the depressions within it. There were imprints from a textile of coarse linen weave on the exterior of some of the edge fittings.It seems that the casket from Haldum had the same construction as the Bamberg casket (figs. 9 and 10). Each of the four sides of the Bamberg casket has, at its centre, a raised semicircular area covered by fittings. The exterior is decorated with a mask and there is a hole on the inside. The bolts of the lid presumably engaged with these holes when the casket was locked. Carved grooves in the wood under the ornamental plates of the lid lead out by way of the holes into the four semicircles. The semicircular fittings of the Haldum casket are, with regard to size and shape, completely identical to the mask fittings seen on the Bamberg casket. One of them is, as mentioned above, rusted to the lock, the bolt of which has been pushed into a hole on its inner surface. Consequently, its function is clear; it is also clear that the casket was locked when placed in the grave.The lid of the Bamberg casket is divided by ornamental bands into four triangular fields (fig. 11). In one of these fields (A), a T-shaped keyhole is apparent, and in continuation of this there is a slot for a slide bar. In the field opposite (C), there is a small hole and each of other fields (B and D) has a partly damaged slide-bar slot. We are so fortunate that the fittings surviving from the Haldum casket include slide bars, bolts and other lock parts that have been lost from the Bamberg casket.It is possible to place the lock and the various fittings from the Haldum casket in a square of the same dimensions as the lid of the Bamberg casket. In the fields created by arranging the zip-shaped fittings to form a diagonal cross, there is space for the lock and the three triangular fittings (fig. 11). The excavation photo in fig. 12 shows the three types of fittings in their original positions. In continuation of the keyhole, the lock has a small slide bar whereby the bolt was pushed into one of the semicircular fittings (side A). The forks of the lock plate extend down on either side of this fitting, demonstrating that there was a central depression in the four sides of lid in order to accommodate the semicircular fittings, as seen on the Bamberg casket. In the triangular fitting, which was located opposite the lock (side C), there is also a small slide bar but no slot in which it could move. Similarly, the wood imprint on the back shows that there was no depression to allow a bolt to be pushed back and forth. On the corresponding side of the lid of the Bamberg casket, the carved depression for the bolt is less marked than on the other sides. On the two remaining triangular fittings from the Haldum casket, the slide bars are located in 15 mm long slots (sides B and D). On the reverse, clear depressions are seen in the wood imprint in which the bolts were slid back and forth (fig. 13). If the fittings are arranged in this way, all the pieces show the same longitudinal direction of the wood imprints on their reverse. This indicates that the casket lid was made from one piece of wood.As is apparent from the carvings on the Bamberg casket, the slide bars of the closing mechanism were located close to the centre of the lid. The hidden grooves for the bolts run from here, under the ornamental plates, and emerge at the edge of the lid. Apparently, the Haldum casket did not have ornamental plates screening the grooves for the bolts. As a consequence, the triangular fittings with the slide bars were placed close to the edge of the lid so that they met the semicircular fittings. In this way it was only necessary to have short grooves for the bolts, and these were covered by the fittings.The way in which the lid and the casket are fitted to one another, together with the absence of hinges, indicates that the lid was loose and was lifted completely off in order to open the box. The bolt opposite the lock (side C) was permanently pushed forwards and was the first to be pushed into the matching semicircular fitting, after which the lid was tilted down into place. After this, the two bolts at the sides (B and D) were extended to keep the lid fastened. Finally, the lock’s bolt was pushed into place and the casket was then locked.By observing the curvature of the striker plate, the triangular fittings, the zip-shaped fittings and some of the edge fittings, which have a curved cross-section, it is possible to reconstruct the shape of the lid (see fig. 10). Its height was c. 45 mm. The rivet must have marked the centre of the lid, corresponding to the cruciform fitting on the lid of the Bamberg casket.The body of the Bamberg casket was assembled by pushing the end surface of one side against the side surface of the next. The wood imprints on the corner plates of the Haldum casket show that the same technique was also used here. It is apparent from these wood imprints, as well as the distance between front and back of the semicircular fittings, that the sides were about 10 mm thick. The wood imprints on the inner side of the semicircular fittings show that the tree rings on the side pieces ran vertically. Had they run horizontally, this would have rendered these curves a weak point.The surviving remains of the Haldum casket show a surprising similarity to the Bamberg casket. There is, however, nothing to indicate that the casket from Haldum was as magnificently decorated, but the now completely vanished oak wood casket may possibly have been decorated with both carvings and paintings. Furthermore, the casket originally had edge fittings greater than 3 mm in width which, in themselves, would also have constituted considerable ornamentation. This fact became evident from construction of the replica (fig. 14). The latter also confirmed the reconstruction of the Haldum casket and its complicated closing mechanism.The Haldum find shows that the Bamberg casket, with its special construction, is not unique, and two further finds kept at Danmark’s National Museum indicate that caskets of this type were perhaps more widespread than previously assumed. One is a cruciform fitting of gilt bronze (fig. 15). The four transepts end in stylised animal heads, and at the centre is a hemispherical raised area. At the centre of the lid of the Bamberg casket there is a cruciform fitting also with animal heads at the ends of the transepts, and in the middle sits a hemispherical rock crystal (fig. 16). The similarity to the former fitting is striking, and it seems likely that the artefact represents a lid fitting for a casket of Bamberg type. The other artefact is a cruciform fitting of sheet bronze with open-work sections between the limbs of the cross and a circular hole at its centre (fig. 17). The fitting is part-finished and of the same type as the first mentioned, but a somewhat different variant. The two fittings were found in an old ford across Halleby Å in Western Zealand near the rich Viking Age settlement at Tissø. They were recovered together with the remains of a tool chest.The grave in which the Haldum casket was found is presumed to be that of a woman because beads and small locked caskets are typical woman’s equipment in Viking Age graves. However, such grave goods have also been found in a few cases in men’s graves. The whetstone gives no indication of the sex of the deceased because this type of artefact was commonly included as grave goods in both men’s and women’s graves. The great similarity of Haldum casket to the Bamberg casket dates the grave to the second half of the 10th century.The style of the Bamberg casket indicates that it was produced in Denmark or Southern Scandinavia. Recently, however, attention has been drawn to the fact that the Mammen style also appears over a wider area. Finds from areas where the Vikings settled outside Scandinavia– from The British Isles to Russia – indicate that craft work in the Mammen style could also have been produced there. The finding of the Haldum casket does, however, add weight to the conclusion that the Bamberg casket was produced in Denmark. This is also the case for the two fittings from Halleby Å if the interpretation presented here is correct. However, whether boxes of this type were produced in one particular place or are the work of one or more travelling craftsmen remains to be ascertained.Jens JeppesenMarianne SchwartzMoesgård Museum

In this issue of Journal of Disaster Research, we introduce nine papers on societal responses to recent catastrophic disasters with special focus on long-term recovery processes in Japan and the United States. As disaster impacts increase, we also find that recovery times take longer and the processes for recovery become more complicated. On January 17th of 1995, a magnitude 7.2 earthquake hit the Hanshin and Awaji regions of Japan, resulting in the largest disaster in Japan in 50 years. In this disaster which we call the Kobe earthquake hereafter, over 6,000 people were killed and the damage and losses totaled more than 100 billion US dollars. The long-term recovery from the Kobe earthquake disaster took more than ten years to complete. One of the most important responsibilities of disaster researchers has been to scientifically monitor and record the long-term recovery process following this unprecedented disaster and discern the lessons that can be applied to future disasters. The first seven papers in this issue present some of the key lessons our research team learned from the studying the long-term recovery following the Kobe earthquake disaster. We have two additional papers that deal with two recent disasters in the United States – the terrorist attacks on World Trade Center in New York on September 11 of 2001 and the devastation of New Orleans by the 2005 Hurricane Katrina and subsequent levee failures. These disasters have raised a number of new research questions about long-term recovery that US researchers are studying because of the unprecedented size and nature of these disasters’ impacts. Mr. Mammen’s paper reviews the long-term recovery processes observed at and around the World Trade Center site over the last six years. Ms. Johnson’s paper provides a detailed account of the protracted reconstruction planning efforts in the city of New Orleans to illustrate a set of sufficient and necessary conditions for successful recovery. All nine papers in this issue share a theoretical framework for long-term recovery processes which we developed based first upon the lessons learned from the Kobe earthquake and later expanded through observations made following other recent disasters in the world. The following sections provide a brief description of each paper as an introduction to this special issue. 1. The Need for Multiple Recovery Goals After the 1995 Kobe earthquake, the long-term recovery process began with the formulation of disaster recovery plans by the City of Kobe – the most severely impacted municipality – and an overarching plan by Hyogo Prefecture which coordinated 20 impacted municipalities; this planning effort took six months. Before the Kobe earthquake, as indicated in Mr. Maki’s paper in this issue, Japanese theories about, and approaches to, recovery focused mainly on physical recovery, particularly: the redevelopment plans for destroyed areas; the location and standards for housing and building reconstruction; and, the repair and rehabilitation of utility systems. But the lingering problems of some of the recent catastrophes in Japan and elsewhere indicate that there are multiple dimensions of recovery that must be considered. We propose that two other key dimensions are economic recovery and life recovery. The goal of economic recovery is the revitalization of the local disaster impacted economy, including both major industries and small businesses. The goal of life recovery is the restoration of the livelihoods of disaster victims. The recovery plans formulated following the 1995 Kobe earthquake, including the City of Kobe’s and Hyogo Prefecture’s plans, all stressed these two dimensions in addition to physical recovery. The basic structure of both the City of Kobe’s and Hyogo Prefecture’s recovery plans are summarized in Fig. 1. Each plan has three elements that work simultaneously. The first and most basic element of recovery is the restoration of damaged infrastructure. This helps both physical recovery and economic recovery. Once homes and work places are recovered, Life recovery of the impacted people can be achieved as the final goal of recovery. Figure 2 provides a “recovery report card” of the progress made by 2006 – 11 years into Kobe’s recovery. Infrastructure was restored in two years, which was probably the fastest infrastructure restoration ever, after such a major disaster; it astonished the world. Within five years, more than 140,000 housing units were constructed using a variety of financial means and ownership patterns, and exceeding the number of demolished housing units. Governments at all levels – municipal, prefectural, and national – provided affordable public rental apartments. Private developers, both local and national, also built condominiums and apartments. Disaster victims themselves also invested a lot to reconstruct their homes. Eleven major redevelopment projects were undertaken and all were completed in 10 years. In sum, the physical recovery following the 1995 Kobe earthquake was extensive and has been viewed as a major success. In contrast, economic recovery and life recovery are still underway more than 13 years later. Before the Kobe earthquake, Japan’s policy approaches to recovery assumed that economic recovery and life recovery would be achieved by infusing ample amounts of public funding for physical recovery into the disaster area. Even though the City of Kobe’s and Hyogo Prefecture’s recovery plans set economic recovery and life recovery as key goals, there was not clear policy guidance to accomplish them. Without a clear articulation of the desired end-state, economic recovery programs for both large and small businesses were ill-timed and ill-matched to the needs of these businesses trying to recover amidst a prolonged slump in the overall Japanese economy that began in 1997. “Life recovery” programs implemented as part of Kobe’s recovery were essentially social welfare programs for low-income and/or senior citizens. 2. Requirements for Successful Physical Recovery Why was the physical recovery following the 1995 Kobe earthquake so successful in terms of infrastructure restoration, the replacement of damaged housing units, and completion of urban redevelopment projects? There are at least three key success factors that can be applied to other disaster recovery efforts: 1) citizen participation in recovery planning efforts, 2) strong local leadership, and 3) the establishment of numerical targets for recovery. Citizen participation As pointed out in the three papers on recovery planning processes by Mr. Maki, Mr. Mammen, and Ms. Johnson, citizen participation is one of the indispensable factors for successful recovery plans. Thousands of citizens participated in planning workshops organized by America Speaks as part of both the World Trade Center and City of New Orleans recovery planning efforts. Although no such workshops were held as part of the City of Kobe’s recovery planning process, citizen participation had been part of the City of Kobe’s general plan update that had occurred shortly before the earthquake. The City of Kobe’s recovery plan is, in large part, an adaptation of the 1995-2005 general plan. On January 13 of 1995, the City of Kobe formally approved its new, 1995-2005 general plan which had been developed over the course of three years with full of citizen participation. City officials, responsible for drafting the City of Kobe’s recovery plan, have later admitted that they were able to prepare the city’s recovery plan in six months because they had the preceding three years of planning for the new general plan with citizen participation. Based on this lesson, Odiya City compiled its recovery plan based on the recommendations obtained from a series of five stakeholder workshops after the 2004 Niigata Chuetsu earthquake. <strong>Fig. 1. </strong> Basic structure of recovery plans from the 1995 Kobe earthquake. <strong>Fig. 2. </strong> “Disaster recovery report card” of the progress made by 2006. Strong leadership In the aftermath of the Kobe earthquake, local leadership had a defining role in the recovery process. Kobe’s former Mayor, Mr. Yukitoshi Sasayama, was hired to work in Kobe City government as an urban planner, rebuilding Kobe following World War II. He knew the city intimately. When he saw damage in one area on his way to the City Hall right after the earthquake, he knew what levels of damage to expect in other parts of the city. It was he who called for the two-month moratorium on rebuilding in Kobe city on the day of the earthquake. The moratorium provided time for the city to formulate a vision and policies to guide the various levels of government, private investors, and residents in rebuilding. It was a quite unpopular policy when Mayor Sasayama announced it. Citizens expected the city to be focusing on shelters and mass care, not a ban on reconstruction. Based on his experience in rebuilding Kobe following WWII, he was determined not to allow haphazard reconstruction in the city. It took several years before Kobe citizens appreciated the moratorium. Numerical targets Former Governor Mr. Toshitami Kaihara provided some key numerical targets for recovery which were announced in the prefecture and municipal recovery plans. They were: 1) Hyogo Prefecture would rebuild all the damaged housing units in three years, 2) all the temporary housing would be removed within five years, and 3) physical recovery would be completed in ten years. All of these numerical targets were achieved. Having numerical targets was critical to directing and motivating all the stakeholders including the national government’s investment, and it proved to be the foundation for Japan’s fundamental approach to recovery following the 1995 earthquake. 3. Economic Recovery as the Prime Goal of Disaster Recovery In Japan, it is the responsibility of the national government to supply the financial support to restore damaged infrastructure and public facilities in the impacted area as soon as possible. The long-term recovery following the Kobe earthquake is the first time, in Japan’s modern history, that a major rebuilding effort occurred during a time when there was not also strong national economic growth. In contrast, between 1945 and 1990, Japan enjoyed a high level of national economic growth which helped facilitate the recoveries following WWII and other large fires. In the first year after the Kobe earthquake, Japan’s national government invested more than US$ 80 billion in recovery. These funds went mainly towards the repair and reconstruction of infrastructure and public facilities. Now, looking back, we can also see that these investments also nearly crushed the local economy. Too much money flowed into the local economy over too short a period of time and it also did not have the “trickle-down” effect that might have been intended. To accomplish numerical targets for physical recovery, the national government awarded contracts to large companies from Osaka and Tokyo. But, these large out-of-town contractors also tended to have their own labor and supply chains already intact, and did not use local resources and labor, as might have been expected. Essentially, ten years of housing supply was completed in less than three years, which led to a significant local economic slump. Large amounts of public investment for recovery are not necessarily a panacea for local businesses, and local economic recovery, as shown in the following two examples from the Kobe earthquake. A significant national investment was made to rebuild the Port of Kobe to a higher seismic standard, but both its foreign export and import trade never recovered to pre-disaster levels. While the Kobe Port was out of business, both the Yokohama Port and the Osaka Port increased their business, even though many economists initially predicted that the Kaohsiung Port in Chinese Taipei or the Pusan Port in Korea would capture this business. Business stayed at all of these ports even after the reopening of the Kobe Port. Similarly, the Hanshin Railway was severely damaged and it took half a year to resume its operation, but it never regained its pre-disaster readership. In this case, two other local railway services, the JR and Hankyu lines, maintained their increased readership even after the Hanshin railway resumed operation. As illustrated by these examples, pre-disaster customers who relied on previous economic output could not necessarily afford to wait for local industries to recover and may have had to take their business elsewhere. Our research suggests that the significant recovery investment made by Japan’s national government may have been a disincentive for new economic development in the impacted area. Government may have been the only significant financial risk-taker in the impacted area during the national economic slow-down. But, its focus was on restoring what had been lost rather than promoting new or emerging economic development. Thus, there may have been a missed opportunity to provide incentives or put pressure on major businesses and industries to develop new businesses and attract new customers in return for the public investment. The significant recovery investment by Japan’s national government may have also created an over-reliance of individuals on public spending and government support. As indicated in Ms. Karatani’s paper, individual savings of Kobe’s residents has continued to rise since the earthquake and the number of individuals on social welfare has also decreased below pre-disaster levels. Based on our research on economic recovery from the Kobe earthquake, at least two lessons emerge: 1) Successful economic recovery requires coordination among all three recovery goals – Economic, Physical and Life Recovery, and 2) “Recovery indices” are needed to better chart recovery progress in real-time and help ensure that the recovery investments are being used effectively. Economic recovery as the prime goal of recovery Physical recovery, especially the restoration of infrastructure and public facilities, may be the most direct and socially accepted provision of outside financial assistance into an impacted area. However, lessons learned from the Kobe earthquake suggest that the sheer amount of such assistance may not be effective as it should be. Thus, as shown in Fig. 3, economic recovery should be the top priority goal for recovery among the three goals and serve as a guiding force for physical recovery and life recovery. Physical recovery can be a powerful facilitator of post-disaster economic development by upgrading social infrastructure and public facilities in compliance with economic recovery plans. In this way, it is possible to turn a disaster into an opportunity for future sustainable development. Life recovery may also be achieved with a healthy economic recovery that increases tax revenue in the impacted area. In order to achieve this coordination among all three recovery goals, municipalities in the impacted areas should have access to flexible forms of post-disaster financing. The community development block grant program that has been used after several large disasters in the United States, provide impacted municipalities with a more flexible form of funding and the ability to better determine what to do and when. The participation of key stakeholders is also an indispensable element of success that enables block grant programs to transform local needs into concrete businesses. In sum, an effective economic recovery combines good coordination of national support to restore infrastructure and public facilities and local initiatives that promote community recovery. Developing Recovery Indices Long-term recovery takes time. As Mr. Tatsuki’s paper explains, periodical social survey data indicates that it took ten years before the initial impacts of the Kobe earthquake were no longer affecting the well-being of disaster victims and the recovery was completed. In order to manage this long-term recovery process effectively, it is important to have some indices to visualize the recovery processes. In this issue, three papers by Mr. Takashima, Ms. Karatani, and Mr. Kimura define three different kinds of recovery indices that can be used to continually monitor the progress of the recovery. Mr. Takashima focuses on electric power consumption in the impacted area as an index for impact and recovery. Chronological change in electric power consumption can be obtained from the monthly reports of power company branches. Daily estimates can also be made by tracking changes in city lights using a satellite called DMSP. Changes in city lights can be a very useful recovery measure especially at the early stages since it can be updated daily for anywhere in the world. Ms. Karatani focuses on the chronological patterns of monthly macro-statistics that prefecture and city governments collect as part of their routine monitoring of services and operations. For researchers, it is extremely costly and virtually impossible to launch post-disaster projects that collect recovery data continuously for ten years. It is more practical for researchers to utilize data that is already being collected by local governments or other agencies and use this data to create disaster impact and recovery indices. Ms. Karatani found three basic patterns of disaster impact and recovery in the local government data that she studied: 1) Some activities increased soon after the disaster event and then slumped, such as housing construction; 2) Some activities reduced sharply for a period of time after the disaster and then rebounded to previous levels, such as grocery consumption; and 3) Some activities reduced sharply for a while and never returned to previous levels, such as the Kobe Port and Hanshin Railway. Mr. Kimura focuses on the psychology of disaster victims. He developed a “recovery and reconstruction calendar” that clarifies the process that disaster victims undergo in rebuilding their shattered lives. His work is based on the results of random surveys. Despite differences in disaster size and locality, survey data from the 1995 Kobe earthquake and the 2004 Niigata-ken Chuetsu earthquake indicate that the recovery and reconstruction calendar is highly reliable and stable in clarifying the recovery and reconstruction process. <strong>Fig. 3.</strong> Integrated plan of disaster recovery. 4. Life Recovery as the Ultimate Goal of Disaster Recovery Life recovery starts with the identification of the disaster victims. In Japan, local governments in the impacted area issue a “damage certificate” to disaster victims by household, recording the extent of each victim’s housing damage. After the Kobe earthquake, a total of 500,000 certificates were issued. These certificates, in turn, were used by both public and private organizations to determine victim’s eligibility for individual assistance programs. However, about 30% of those victims who received certificates after the Kobe earthquake were dissatisfied with the results of assessment. This caused long and severe disputes for more than three years. Based on the lessons learned from the Kobe earthquake, Mr. Horie’s paper presents (1) a standardized procedure for building damage assessment and (2) an inspector training system. This system has been adopted as the official building damage assessment system for issuing damage certificates to victims of the 2004 Niigata-ken Chuetsu earthquake, the 2007 Noto-Peninsula earthquake, and the 2007 Niigata-ken Chuetsu Oki earthquake. Personal and family recovery, which we term life recovery, was one of the explicit goals of the recovery plan from the Kobe earthquake, but it was unclear in both recovery theory and practice as to how this would be measured and accomplished. Now, after studying the recovery in Kobe and other regions, Ms. Tamura’s paper proposes that there are seven elements that define the meaning of life recovery for disaster victims. She recently tested this model in a workshop with Kobe disaster victims. The seven elements and victims’ rankings are shown in Fig. 4. Regaining housing and restoring social networks were, by far, the top recovery indicators for victims. Restoration of neighborhood character ranked third. Demographic shifts and redevelopment plans implemented following the Kobe earthquake forced significant neighborhood changes upon many victims. Next in line were: having a sense of being better prepared and reducing their vulnerability to future disasters; regaining their physical and mental health; and restoration of their income, job, and the economy. The provision of government assistance also provided victims with a sense of life recovery. Mr. Tatsuki’s paper summarizes the results of four random-sample surveys of residents within the most severely impacted areas of Hyogo Prefecture. These surveys were conducted biannually since 1999,. Based on the results of survey data from 1999, 2001, 2003, and 2005, it is our conclusion that life recovery took ten years for victims in the area impacted significantly by the Kobe earthquake. Fig. 5 shows that by comparing the two structural equation models of disaster recovery (from 2003 and 2005), damage caused by the Kobe earthquake was no longer a determinant of life recovery in the 2005 model. It was still one of the major determinants in the 2003 model as it was in 1999 and 2001. This is the first time in the history of disaster research that the entire recovery process has been scientifically described. It can be utilized as a resource and provide benchmarks for monitoring the recovery from future disasters. <strong>Fig. 4.</strong> Ethnographical meaning of “life recovery” obtained from the 5th year review of the Kobe earthquake by the City of Kobe. <strong>Fig. 5.</strong> Life recovery models of 2003 and 2005. 6. The Need for an Integrated Recovery Plan The recovery lessons from Kobe and other regions suggest that we need more integrated recovery plans that use physical recovery as a tool for economic recovery, which in turn helps disaster victims. Furthermore, we believe that economic recovery should be the top priority for recovery, and physical recovery should be regarded as a tool for stimulating economic recovery and upgrading social infrastructure (as shown in Fig. 6). With this approach, disaster recovery can help build the foundation for a long-lasting and sustainable community. Figure 6 proposes a more detailed model for a more holistic recovery process. The ultimate goal of any recovery process should be achieving life recovery for all disaster victims. We believe that to get there, both direct and indirect approaches must be taken. Direct approaches include: the provision of funds and goods for victims, for physical and mental health care, and for housing reconstruction. Indirect approaches for life recovery are those which facilitate economic recovery, which also has both direct and indirect approaches. Direct approaches to economic recovery include: subsidies, loans, and tax exemptions. Indirect approaches to economic recovery include, most significantly, the direct projects to restore infrastructure and public buildings. More subtle approaches include: setting new regulations or deregulations, providing technical support, and creating new businesses. A holistic recovery process needs to strategically combine all of these approaches, and there must be collaborative implementation by all the key stakeholders, including local governments, non-profit and non-governmental organizations (NPOs and NGOs), community-based organizations (CBOs), and the private sector. Therefore, community and stakeholder participation in the planning process is essential to achieve buy-in for the vision and desired outcomes of the recovery plan. Securing the required financial resources is also critical to successful implementation. In thinking of stakeholders, it is important to differentiate between supporting entities and operating agencies. Supporting entities are those organizations that supply the necessary funding for recovery. Both Japan’s national government and the federal government in the U.S. are the prime supporting entities in the recovery from the 1995 Kobe earthquake and the 2001 World Trade Center recovery. In Taiwan, the Buddhist organization and the national government of Taiwan were major supporting entities in the recovery from the 1999 Chi-Chi earthquake. Operating agencies are those organizations that implement various recovery measures. In Japan, local governments in the impacted area are operating agencies, while the national government is a supporting entity. In the United States, community development block grants provide an opportunity for many operating agencies to implement various recovery measures. As Mr. Mammen’ paper describes, many NPOs, NGOs, and/or CBOs in addition to local governments have had major roles in implementing various kinds programs funded by block grants as part of the World Trade Center recovery. No one, single organization can provide effective help for all kinds of disaster victims individually or collectively. The needs of disaster victims may be conflicting with each other because of their diversity. Their divergent needs can be successfully met by the diversity of operating agencies that have responsibility for implementing recovery measures. In a similar context, block grants made to individual households, such as microfinance, has been a vital recovery mechanism for victims in Thailand who suffered from the 2004 Sumatra earthquake and tsunami disaster. Both disaster victims and government officers at all levels strongly supported the microfinance so that disaster victims themselves would become operating agencies for recovery. Empowering individuals in sustainable life recovery is indeed the ultimate goal of recovery. <strong>Fig. 6.</strong> A holistic recovery policy model.

In this research work, a die steel tool was used to join the two aluminium sheets together on a radial drill machine. For this, a cylindrical-shaped tool was fabricated. This tool is then clamped into the drill machine tool post. This rotating tool is then inserted/indented into the workpiece thus generating heat due to friction. The of the deformation of aluminium starts near the vicinity of the die steel tool impression. The tool transferred the soft material from the tip to the plunger. The plunger is in contact with the Aluminum sheet. Soften material is forged on the sheet with the help of a plunger and thus creating a solid phase joint between the Aluminum sheets. Three-dimensional numerical modelings were performed on Ansys software. A 3-D heat transfer model was used to solve the problem of friction stir spot welding (FSSW). This model was solved by applying the energy conservation equation. This model involves the heat generated at the boundary of the workpiece (AA) and the rotating tool and for study, the problem, steady-state heat transfer equation was used. The numerically computed and the measured values are compared to validate the results.

AbstractTwo-dimensional laser-induced incandescence (LII) measurements usually involve the use of a cylindrical lens to illuminate the planar region of interest. This creates a varying laser fluence and sheet width in the imaged flame region which could lead to large uncertainties in the quantification of the 2D LII signals into soot volume fraction distributions. To investigate these effects, 2D LII measurements using a wide range of laser pulse energies were performed on a premixed flat ethylene–air flame while employing a cylindrical lens to focus the laser sheet. Using shorter focal length of the focusing lens resulted in larger variation of the LII signal profiles across the flame. A heat – and – mass – transfer - based LII model was also used to simulate the measurements and good agreement was found. The ratio between focal length (FL) and image length (IL) was introduced as a useful parameter for estimating the bias in estimated soot volume fractions across the flame. The general recommendation is to maximize this FL/IL ratio in an experiment, which in practice means the use of a long focal length lens. Furthermore, the best choices of laser fluence and detection gate width are discussed based on results from these simulations.

AbstractEliminating topological defects to achieve monodomain liquid crystals is highly significant for the fundamental studies of soft matter and building long-range ordered materials. However, liquid crystals are metastable and sensitive to external stimuli, such as flow, confinement, and electromagnetic fields, which cause their intrinsic polycrystallinity and topological defects. Here, we achieve the monodomain liquid crystals of graphene oxide over 30 cm through boundary-free sheargraphy. The obtained monodomain liquid crystals exhibit large-area uniform alignment of sheets, which has the same optical polarized angle and intensity. The monodomain liquid crystals provide bidirectionally ordered skeletons, which can be applied as lightweight thermal management materials with bidirectionally high thermal and electrical conductivity. Furthermore, we extend the controllable topology of two-dimensional colloids by introducing singularities and disclinations in monodomain liquid crystals. Topological structures with defect strength from − 2 to + 2 were realized. This work provides a facile methodology to study the structural order of soft matter at a macroscopic level, facilitating the fabrication of metamaterials with tunable and highly anisotropic architectures.

AbstractThe two-dimensional multi-angle light scattering (2D-MALS) technique has been extended for single-shot size measurements of soot aggregates in flames. Six cameras are used for instantaneous acquisition of the elastic scattering from the aggregates at different directions between 10 to 90$$^\circ$$ ∘ of a laser light sheet. Two diluted ethylene (50 and 60% by volume of $$\hbox {C}_2\hbox {H}_4$$ C 2 H 4 fuel diluted with inert $$\hbox {N}_2$$ N 2 ) coflow laminar diffusion flames with little flickering are used as proof of concept. Results of instantaneous, average and fluctuating 2D fields of the effective radii of gyration, which are expected to characterize the size of the aggregates, compare well with the literature, demonstrating the applicability of the proposed sizing method to weakly unsteady combustion processes.

Abstract Emerging three-dimensional (3D) printing techniques for soft active materials have demonstrated fascinating applications in various areas including programmable and reconfigurable structures, tissue engineering, and soft robotics. For example, polymeric gels, which consist of polymer networks swollen with solvent molecules, are capable of deforming and swelling/deswelling in response to external stimuli. Although polymeric gels are used to print structures, little attention has been paid to the effect of printing parameters on the cross-sectional shape of 3D-printed gel filaments or further to the dynamic responses of the printed structures. Due to the flow of the precursor solution before fully cured, the cross section of a printed gel filament is usually asymmetric. When immersed in water, the asymmetry in the cross section causes the printed filament to bend, and the interdiffusion of the two solvents leads to the alternation in bending direction. The bending curvature and response rate can be adjusted by turning printing parameters. As applications of this mechanism, we demonstrated various types of gel structures, capable of deforming from 1D strips to 2D spiral or sinusoidal shapes, warping from 2D flat sheet to 3D cylindrical helix when swollen, or wrapping and manipulating objects under external stimuli.

Abstract Background Artifacts fault image quality but handling several factors can affect it. This study was conducted to investigate the effect of object size on artifacts in cone-beam computed tomography systems. Methods Five phantoms, each containing a titanium implant in a sheep bone block, were fabricated of various sizes ranging from XS to XL: The M phantom was the same size as the device’s field of view (FOV). The L and XL phantoms were 20 and 40% larger than the FOV while the S and XS phantoms were 20 and 40% smaller than FOV, respectively. Ballistic gelatin was used to fill the phantoms. Phantoms were scanned by NewTom VGI and HDXWill Q-FACE. The mean and standard deviation (SD) of gray values in each 120 ROI was obtained by OnDemand software. The contrast to noise ratio (CNR) was also calculated. Results The gray value in S and M phantoms were more homogenous. The lowest SD value (10.20) was found in S phantom. The highest value for SD (125.16) was observed in XL phantom. The lowest (4.47) and highest (9.92) CNR were obtained in XL and S phantoms, respectively. HDXWill Q-FACE recorded a higher SD and a lower CNR than NewTom VGI (P < 0.05). Conclusion Object dimensions of the FOV size or up to 20% smaller provided better image quality. Since the dimensions of soft tissue in most patients are larger than the selective FOV, it is recommended that in CBCT artifacts studies, an object with dimensions closer to the patient’s dimensions be used to better relate the results with the clinical condition, because the sample dimensions affect the amount of artifacts.

The aim of this report is to present a new two-piece thyroid-neck phantom produced by the concurrent use of epoxy resin and poly(methyl methacrylate) (PMMA: plexiglass) soft tissue equivalent materials. Accordingly, mass attenuation coefficients of the epoxy resin and the plexiglass compounds were obtained from simulation (NIST XCOM 3.1) and measurements (practical dosimetry) and compared to those related to human soft tissue (ICRU 44). The thyroid-neck phantom and thyroid gland dimensions were derived from scientific references and the atlas of human anatomy, respectively. The thyroid phantom was designed by CATIA V5R16 software and produced by the epoxy resin compound by three-dimensional printer. Other organs were designed by ProNest software and made by the plexiglass sheets by CNC laser cutting machine. The mass attenuation coefficients for the epoxy resin (50 keV- 20 MeV) and the plexiglass (0-20 MeV) were comparable to human soft tissue (ICRU 44), all with standard relative deviation beneath 5%. In addition, the SPECT images indicated the similarity between human thyroid tissue and its phantom. In conclusion, this study proves the feasibility and reliability of epoxy resin application in the production of two-piece thyroid-neck phantom. This phantom can be applied in the calibration of gamma camera systems, dosimetry and gamma spectrometry in the nuclear medicine field.

Abstract A methodology to test the interlayer bonding strength of two-dimensional (2D) surfaces and associated one(1D)- and two(2D)- dimensional surface defects using scanning tunneling microscope (STM) tip-induced deformation, is demonstrated. Surface elastic deformation characteristics of soft 2D monatomic sheets of graphene and graphite in contrast to NbSe2 indicates related association with the underlying local bonding configurations. Surface deformation of 2D graphitic moiré patterns reveal the inter-layer van der Waals (vdW) strength varying across its domains. These results help in the understanding of the comparable interlayer bonding strength of 1D grain boundary (GB) as well as the grains. Anomalous phenomena related to probing 2D materials at small gap distances as a function of strain are discussed.

AbstractCertain design strategies appear repeatedly in a variety of biological structures. One such motif consists of a soft and pliable interface joining much larger and stiffer elements. Examples include the craniofacial sutures between the bones of the skull, the sutures between the bony plates in shell of turtles and the periodontal ligament between teeth and their sockets. Yet the detailed mechanics of these systems are not fully understood.Turtles are believed to have existed already in the early Triassic, about 200 million years ago. They are thus one of the oldest non-extinct vertebrates. Their shell is therefore a particularly attractive subject for investigation since it has developed and conserved through such an extremely long evolutionary process and has achieved a highly optimized structure.The turtle shell has a ‘sandwich’ structure typical of flat bones like the skull of vertebrates. It consists of two external, relatively thin sheets of dense bone (internal endocortical and external exocortical bone plates) which contain very few voids, and between them a thick and very porous spongy bone layer. At the mid-distance between adjacent ribs the dermal bones are separated by soft sutures which have a unique and complex 3-D shape.The primary function of the shell is to protect the turtle from external trauma, and therefore it has to be stiff. However excessive stiffness may result in microdamage accumulation as a result of everyday activities like minor impact, and decrease the efficiency of respiration and locomotion. We speculate that the structure and architecture of the sutures allow easy deformation of the shell at small loads but cause it to become considerably more rigid at larger loads, reminiscent of composite materials with interlocking elements. We hypothesize that this mechanical property is related to the putative function of the suture in the turtle shell.In order to examine this hypothesis we studied samples obtained from shells of the red eared slider turtle (Chrysemys scripta elegans). We used several imaging techniques (micro-computed tomography, scanning electron microscopy and light microscopy), histology and mechanical testing. Based on these observations we present a concept of the structure-mechanics relationship of the shell, and present a simple mathematical model of the deformation pattern of the suture-containing samples in 3-point bending tests and compare its predictions to our experimental results.

0. IntroductionIf we follow the line of much literature surrounding airports and urban mobility, the emphasis often falls on the fact that these spaces are designed to handle the mega-scale and super-human pace of mass transit. Airports have rightly been associated with velocity, as zones of rapid movement managed by enormous processing systems that guide bodies and things in transit (Pascoe; Pearman; Koolhaas; Gordon; Fuller & Harley). Yet this emphasis tends to ignore the spectrum of tempos and flows that are at play in airport terminals — from stillness to the much exalted hyper-rapidity of mobilized publics in the go-go world of commercial aviation.In this photo essay I'd like to pull a different thread and ask whether it's possible to think of aeromobility in terms of “uneven, differential mobility” (Bissell 280). What would it mean to consider waiting and stillness as forms of bodily engagement operating over a number of different scales and temporalities of movement and anticipation, without privileging speed over stillness? Instead of thinking mobility and stillness as diametrically opposed, can we instead conceive of them as occupying a number of different spatio-temporal registers in a dynamic range of mobility? The following is a provisional "visual ethnography" constructed from photographs of air terminal light boxes I have taken over the last five years (in Amsterdam, London, Chicago, Frankfurt, and Miami). Arranged into a "taxonomy of differentiality", each of these images comes from a slightly different angle, mode or directionality. Each view of these still images displayed in billboard-scale light-emitting devices suggests that there are multiple dimensions of visuality and bodily experience at play in these image-objects. The airport is characterized by an abundance of what appears to be empty space. This may be due to the sheer scale of mass transport, but it also arises from a system of active and non-active zones located throughout contemporary terminals. This photo series emphasises the "emptiness" of these overlooked left-over spaces that result from demands of circulation and construction.1. We Move the WorldTo many travellers, airport gate lounges and their surrounding facilities are loaded with a variety of contradictory associations and affects. Their open warehouse banality and hard industrial sterility tune our bodies to the vast technical and commercial systems that are imbricated through almost every aspect of contemporary everyday life.Here at the departure gate the traveller's body comes to a moment's rest. They are granted a short respite from the anxious routines of check in, body scans, security, information processing, passport scanning, itineraries, boarding procedures and wayfaring the terminal. The landside processing system deposits them at this penultimate point before final propulsion into the invisible airways that pipe them into their destination. We hear the broadcasting of boarding times, check-in times, name's of people that break them away from stillness, forcing people to move, to re-arrange themselves, or to hurry up. Along the way the passenger encounters a variety of techno-spatial experiences that sit at odds with the overriding discourse of velocity, speed and efficiency that lie at the centre of our social understanding of air travel. The airline's phantasmagorical projections of itself as guarantor and enabler of mass mobilities coincides uncomfortably with the passenger's own wish-fulfilment of escape and freedom.In this we can agree with the designer Bruce Mau when he suggests that these projection systems, comprised of "openings of every sort — in schedules, in urban space, on clothes, in events, on objects, in sightlines — are all inscribed with the logic of the market” (Mau 7). The advertising slogans and images everywhere communicate the dual concept that the aviation industry can deliver the world to us on time while simultaneously porting us to any part of the world still willing to accept Diners, VISA or American Express. At each point along the way these openings exhort us to stop, to wait in line, to sit still or to be patient. The weird geographies depicted by the light boxes appear like interpenetrating holes in space and time. These travel portals are strangely still, and only activated by the impending promise of movement.Be still and relax. Your destination is on its way. 2. Attentive AttentionAlongside the panoramic widescreen windows that frame the choreography of the tarmac and flight paths outside, appear luminous advertising light boxes. Snapped tightly to grid and locked into strategic sightlines and thoroughfares, these wall pieces are filled with a rotating menu of contemporary airport haiku and ersatz Swiss graphic design.Mechanically conditioned air pumped out of massive tubes creates the atmosphere for a very particular amalgam of daylight, tungsten, and fluorescent light waves. Low-oxygen-emitting indoor plants are no match for the diesel-powered plant rooms that maintain the constant flow of air to every nook and cranny of this massive processing machine. As Rem Koolhaas puts it, "air conditioning has launched the endless building. If architecture separates buildings, air conditioning unites them" (Koolhaas). In Koolhaas's lingo, these are complex "junkspaces" unifying, colliding and coalescing a number of different circulatory systems, temporalities and mobilities.Gillian Fuller reminds us there is a lot of stopping and going and stopping in the global circulatory system typified by air-terminal-space.From the packing of clothes in fixed containers to strapping your belt – tight and low – stillness and all its requisite activities, technologies and behaviours are fundamental to the ‘flow’ architectures that organize the motion of the globalizing multitudes of today (Fuller, "Store" 63). It is precisely this functional stillness organised around the protocols of store and forward that typifies digital systems, the packet switching of network cultures and the junkspace of airports alike.In these zones of transparency where everything is on view, the illuminated windows so proudly brought to us by J C Decaux flash forward to some idealized moment in the future. In this anticipatory moment, the passenger's every fantasy of in-flight service is attended to. The ultimate in attentiveness (think dimmed lights, soft pillows and comfy blankets), this still image is captured from an improbable future suspended behind the plywood and steel seating available in the moment —more reminiscent of park benches in public parks than the silver-service imagined for the discerning traveller.3. We Know ChicagoSelf-motion is itself a demonstration against the earth-binding weight of gravity. If we climb or fly, our defiance is greater (Appleyard 180).The commercial universe of phones, cameras, computer network software, financial instruments, and an array of fancy new gadgets floating in the middle of semi-forgotten transit spaces constitutes a singular interconnected commercial organism. The immense singularity of these claims to knowledge and power loom solemnly before us asserting their rights in the Esperanto of "exclusive rollover minutes", "nationwide long distance", "no roaming charges" and insider local knowledge. The connective tissue that joins one part of the terminal to a commercial centre in downtown Chicago is peeled away, revealing techno-veins and tendrils reaching to the sky. It's a graphic view that offers none of the spectacular openness and flights of fancy associated with the transit lounges located on the departure piers and satellites. Along these circulatory ribbons we experience the still photography and the designer's arrangement of type to attract the eye and lure the body. The blobby diagonals of the telco's logo blend seamlessly with the skyscraper's ribbons of steel, structural exoskeleton and wireless telecommunication cloud.In this plastinated anatomy, the various layers of commercially available techno-space stretch out before the traveller. Here we have no access to the two-way vistas made possible by the gigantic transparent tube structures of the contemporary air terminal. Waiting within the less travelled zones of the circulatory system we find ourselves suspended within the animating system itself. In these arteries and capillaries the flow is spread out and comes close to a halt in the figure of the graphic logo. We know Chicago is connected to us.In the digital logic of packet switching and network effects, there is no reason to privilege the go over the stop, the moving over the waiting. These light box portals do not mirror our bodies, almost at a complete standstill now. Instead they echo the commercial product world that they seek to transfuse us into. What emerges is a new kind of relational aesthetics that speaks to the complex corporeal, temporal, and architectural dimensions of stillness and movement in transit zones: like "a game, whose forms, patterns and functions develop and evolve according to periods and social contexts” (Bourriaud 11). 4. Machine in the CaféIs there a possible line of investigation suggested by the fact that sound waves become visible on the fuselage of jet planes just before they break the sound barrier? Does this suggest that the various human senses are translatable one into the other at various intensities (McLuhan 180)?Here, the technological imaginary contrasts itself with the techno alfresco dining area enclosed safely behind plate glass. Inside the cafes and bars, the best businesses in the world roll out their biggest guns to demonstrate the power, speed and scale of their network coverage (Remmele). The glass windows and light boxes "have the power to arrest a crowd around a commodity, corralling them in chic bars overlooking the runway as they wait for their call, but also guiding them where to go next" (Fuller, "Welcome" 164). The big bulbous plane sits plump in its hangar — no sound barriers broken here. It reassures us that our vehicle is somewhere there in the network, resting at its STOP before its GO. Peeking through the glass wall and sharing a meal with us, this interpenetrative transparency simultaneously joins and separates two planar dimensions — machinic perfection on one hand, organic growth and death on the other (Rowe and Slutsky; Fuller, "Welcome").Bruce Mau is typical in suggesting that the commanding problem of the twentieth century was speed, represented by the infamous image of a US Navy Hornet fighter breaking the sound barrier in a puff of smoke and cloud. It has worked its way into every aspect of the design experience, manufacturing, computation and transport.But speed masks more than it reveals. The most pressing problem facing designers and citizens alike is growth — from the unsustainable logic of infinite growth in GDP to the relentless application of Moore's Law to the digital networks and devices that define contemporary society in the first world. The shift of emphasis from speed to growth as a time-based event with breaking points and moments of rupture has generated new possibilities. "Growth is nonlinear and unpredictable ... Few of us are ready to admit that growth is constantly shadowed by its constitutive opposite, that is equal partners with death” (Mau 497).If speed in part represents a flight from death (Virilio), growth invokes its biological necessity. In his classic study of the persistence of the pastoral imagination in technological America, The Machine in the Garden, Leo Marx charted the urge to idealize rural environments at the advent of an urban industrialised America. The very idea of "the flight from the city" can be understood as a response to the onslaught of technological society and it's deathly shadow. Against the murderous capacity of technological society stood the pastoral ideal, "incorporated in a powerful metaphor of contradiction — a way of ordering meaning and value that clarifies our situation today" (Marx 4). 5. Windows at 35,000 FeetIf waiting and stillness are active forms of bodily engagement, we need to consider the different layers of motion and anticipation embedded in the apprehension of these luminous black-box windows. In The Virtual Window, Anne Friedberg notes that the Old Norse derivation of the word window “emphasizes the etymological root of the eye, open to the wind. The window aperture provides ventilation for the eye” (103).The virtual windows we are considering here evoke notions of view and shelter, open air and sealed protection, both separation from and connection to the outside. These windows to nowhere allow two distinct visual/spatial dimensions to interface, immediately making the visual field more complex and fragmented. Always simultaneously operating on at least two distinct fields, windows-within-windows provide a specialized mode of spatial and temporal navigation. As Gyorgy Kepes suggested in the 1940s, the transparency of windows "implies more than an optical characteristic; it implies a broader spatial order. Transparency means a simultaneous perception of different spatial locations" (Kepes 77).The first windows in the world were openings in walls, without glass and designed to allow air and light to fill the architectural structure. Shutters were fitted to control air flow, moderate light and to enclose the space completely. It was not until the emergence of glass technologies (especially in Holland, home of plate glass for the display of commercial products) that shielding and protection also allowed for unhindered views (by way of transparent glass). This gives rise to the thesis that windows are part of a longstanding architectural/technological system that moderates the dual functions of transparency and separation. With windows, multi-dimensional planes and temporalities can exist in the same time and space — hence a singular point of experience is layered with many other dimensions. Transparency and luminosity "ceases to be that which is perfectly clear and becomes instead that which is clearly ambiguous" (Rowe and Slutsky 45). The light box air-portals necessitate a constant fluctuation and remediation that is at once multi-planar, transparent and "hard to read". They are informatic.From holes in the wall to power lunch at 35,000 feet, windows shape the manner in which light, information, sights, smells, temperature and so on are modulated in society. "By allowing the outside in and the inside out, [they] enable cosmos and construction to innocently, transparently, converge" (Fuller, "Welcome" 163). Laptop, phone, PDA and light box point to the differential mobilities within a matrix that traverses multiple modes of transparency and separation, rest and flight, stillness and speed.6. Can You Feel It?Increasingly the whole world has come to smell alike: gasoline, detergents, plumbing, and junk foods coalesce into the catholic smog of our age (Illich 47).In these forlorn corners of mobile consumption, the dynamic of circulation simultaneously slows and opens out. The surfaces of inscription implore us to see them at precisely the moment we feel unseen, unguided and off-camera. Can you see it, can you feel it, can you imagine the unimaginable, all available to us on demand? Expectation and anticipation give us something to look forward to, but we're not sure we want what's on offer.Air travel radicalizes the separation of the air traveller from ground at one instance and from the atmosphere at another. Air, light, temperature and smell are all screened out or technologically created by the terminal plant and infrastructure. The closer the traveller moves towards stillness, the greater the engagement with senses that may have been ignored by the primacy of the visual in so much of this circulatory space. Smell, hunger, tiredness, cold and hardness cannot be screened out.In this sense, the airplanes we board are terminal extensions, flying air-conditioned towers or groundscrapers jet-propelled into highways of the air. Floating above the horizon, immersed in a set of logistically ordained trajectories and pressurized bubbles, we look out the window and don't see much at all. Whatever we do see, it's probably on the screen in front of us which disconnects us from one space-time-velocity at the same time that it plugs us into another set of relations. As Koolhaas says, junkspace is "held together not by structure, but by skin, like a bubble" (Koolhaas). In these distended bubbles, the traveler momentarily occupies an uncommon transit space where stillness is privileged and velocity is minimized. The traveler's body itself is "engaged in and enacting a whole kaleidoscope of different everyday practices and forms" during the course of this less-harried navigation (Bissell 282).7. Elevator MusicsThe imaginary wheel of the kaleidoscope spins to reveal a waiting body-double occupying the projected territory of what appears to be a fashionable Miami. She's just beyond our reach, but beside her lies a portal to another dimension of the terminal's vascular system.Elevators and the networks of shafts and vents that house them, are to our buildings like veins and arteries to the body — conduits that permeate and structure the spaces of our lives while still remaining separate from the fixity of the happenings around them (Garfinkel 175). The terminal space contains a number of apparent cul-de-sacs and escape routes. Though there's no background music piped in here, another soundtrack can be heard. The Muzak corporation may douse the interior of the elevator with its own proprietary aural cologne, but at this juncture the soundscape is more "open". This functional shifting of sound from figure to ground encourages peripheral hearing, providing "an illusion of distended time", sonically separated from the continuous hum of "generators, ventilation systems and low-frequency electrical lighting" (Lanza 43).There is another dimension to this acoustic realm: “The mobile ecouteur contracts the flows of information that are supposed to keep bodies usefully and efficiently moving around ... and that turn them into functions of information flows — the speedy courier, the networking executive on a mobile phone, the scanning eyes of the consumer” (Munster 18).An elevator is a grave says an old inspector's maxim, and according to others, a mechanism to cross from one world to another. Even the quintessential near death experience with its movement down a long illuminated tunnel, Garfinkel reminds us, “is not unlike the sensation of movement we experience, or imagine, in a long swift elevator ride” (Garfinkel 191).8. States of SuspensionThe suspended figure on the screen occupies an impossible pose in an impossible space: half falling, half resting, an anti-angel for today's weary air traveller. But it's the same impossible space revealed by the airport and bundled up in the experience of flight. After all, the dimension this figures exists in — witness the amount of activity in his suspension — is almost like a black hole with the surrounding universe collapsing into it. The figure is crammed into the light box uncomfortably like passengers in the plane, and yet occupies a position that does not exist in the Cartesian universe.We return to the glossy language of advertising, its promise of the external world of places and products delivered to us by the image and the network of travel. (Remmele) Here we can go beyond Virilio's vanishing point, that radical reversibility where inside and outside coincide. Since everybody has already reached their destination, for Virilio it has become completely pointless to leave: "the inertia that undermines your corporeity also undermines the GLOBAL and the LOCAL; but also, just as much, the MOBILE and the IMMOBILE” (Virilio 123; emphasis in original).In this clinical corner of stainless steel, glass bricks and exit signs hangs an animated suspension that articulates the convergence of a multitude of differentials in one image. Fallen into the weirdest geometry in the world, it's as if the passenger exists in a non-place free of all traces. Flows and conglomerates follow one another, accumulating in the edges, awaiting their moment to be sent off on another trajectory, occupying so many spatio-temporal registers in a dynamic range of mobility.ReferencesAppleyard, Donald.

The Big Pineapple, Big Banana, the Big Potato , Australia positively groans under the weight of big things littered along the highway like jokes awaiting their punch-lines. These commercial road-side enterprises are a constant source of bemusement among Australians and this paper seeks to explore the attraction of the gargantuan and why Australians consider big things to be so funny. Discovering that big things not only give form to national icons but also celebrate the nation's tendency to larrikinism and the associated sardonic, ironic and anti-establishment humour, we are left to consider the role big things may play in the Australian national psyche and how their function as low art turns their collectivity into some strange, impulsive attempt at establishing a system of totems that comes to terms with this big land and its contested ownership. Historically big things like the Colossus of Rhodes, the Pyramids or the Great Wall of China have been physical manifestations of empire and dominion. No laughing matter. But in the United States from the 1920s, particularly in Southern California, we begin to see a profusion of "roadside vernacular architecture" including a big coffee percolator, a big pig, a big corn ear, a big teapot, a big Spanish dancer, a big duck, a big fish and many big hot dogs and big chilli bowls (Heimann and Georges). "Imaginana" is another way to conceptualise these strange forms of cultural production that replicate familiar, safe everyday items (Amdur 12). Early big things, particularly in the United States, had a clearly pragmatic function: to lure car-bound consumers off the highways and into local commercial enterprises with simple, one-to-one signification bringing function to form and high art to low purposes (Gebhard 14). The aim of these big things was to shock, startle and amuse the passing motorist and they took on a humourous edge due to the incongruity of scale and the surreal surprise of reality warping out of all proportion. While big things have a commercial purpose they achieve that purpose because they can be read playfully, always reminding us of the paradox they entail: they act dualistically as both the media and the message, both the referent and the real (Barcan 38). Reading big things as jokes in Freudian terms, we see how they may be eruptions of the unconscious into the mundane (Krahn 158). The first big thing in Australia was the Big Banana, built in Coffs Harbour by an American entomologist, John Landi (Negus). From that time on Australia has had a quirky relationship with big things. The banana is innately funny. The bent phallus, the unique shape, the skin as the standard slapstick cue to pratfall; everything about the banana is an invitation to laugh. Soon the banana was emulated by other funny produce such as the pineapple, the prawn and the lobster and within a decade monstrous agricultural products proliferated beside Australian highways regardless of their innate humour. They were joined by a variety of iconic figures, usually with an obvious connection such as the Big Penguin at the town of Penguin. Big things reinforce notions of national and regional identity: on the national level Australia is portrayed as a land of plenty, a fact emphasized by the sheer vastness of these creations; regionally, these totems function as identity markers and place makers (Barcan 31). Many big things were constructed by migrants and thus can be interpreted as optimistic acts of home making in the vast emptiness of the continent (Barcan 36). There is concern that big things obscure, or even obliterate, the history of regions and the whole continent: the incarcerations, land-grabbing, labour conflicts, corruption and failure. Instead it could be argued that big thing function to both signpost white history and subvert it at the same time: the Big Ned Kelly calling for revolution, the big goldminer looking ever expectant and ever disappointed, the Big Captain Cook in Cairns giving what appears to be a Nazi salute, all point to a larrikin refusal to take the brief and minor white history too seriously. The Australian larrikin sense of humour is mischievous, depreciatory and anti-authoritarian. This sense of humour arises from certain characteristics of the Australian "legend" identified by Ward such as scepticism, egalitarianism and derision towards affectation that are evident in larrikins' confrontations with authority, elaborate practical jokes on each other and the community at large and a "propensity for vulgarising the arts" (Reekie 97). This larrikinism is evident in the way dangerous nuisances (the big crocodile, the big red back spider) and mundane objects (the big jam tin, the big stubby holder, the big mower) are given the same treatment as national icons. There is also the variability of effort and attention to detail, where Aussie "ingenuity" and bush carpentry have been used to turn a good idea into reality in the shortest possible time to produce a very impressionist big koala or just the blob of concrete that is the big strawberry. Ignatius Jones explains: "get your local surfboard maker to cast you a giant prawn in fibreglass and you end up with the cicada that ate Yamba" (Negus). The early documentation of Australian big things was also carried out in a larrikin spirit (Amdur) including the claim that big things are part of an alien conspiracy to make us feel small (Stockwell). Every big thing requires a visionary, a postmodern artist with the passion and the obsession to realise their vision. It is a form of low art, a form of trash culture. But to many who do not frequent galleries and museums, low art is their available form of art and thus becomes their actual art. City planners and the upper middle class tend to denigrate these structures so at odds with their images of beautiful cities, so blatantly bastions of commercialism and so big that they run the risk of obscuring and obliterating real art (Gerbhard 25). Big things are criticised as ugly, kitsch, tacky and giving a wrong impression of a town. There are further concerns that big things allow the tourist to learn without knowing by presenting only one side of the story (Cross 51) and that they make observers minuscule in their presence, dominating the landscape and the attention of tourists (Krahn 165). But looking beyond the aesthetics of the individual instance it becomes apparent that big things also function as a network (Barcan 32), inviting the tourist along the highway of "the arrested fairground (in the) oxymoron of movement" (Krahn 157), offering the hyperreal adventure of collecting the experience, and small mementos, of more big things (Eco 1986). Big things are carnival, inverting social rules, promising some weird utopia (Krahn 171). As a collectivity, the larger psycho-political and metaphysical roles of big things become apparent. For Australia, the crucial question big things raise is the nature of our relationship with the land. Most of white Australia, huddled in cities on the seaboard, has a fear of the empty space at the heart of the continent. Big things are an attempt to assert that the settlers can match the dimensions of the land as, community by community, we write ourselves upon the land. The problem that big things highlight rather than obscure, the problem that can never be sublimated, that constantly erupts from the collective unconscious is that the ownership of the land remains contested, sometimes in the courts, sometimes in the streets, but most importantly in the hearts and dreams of the whole Australian people. All this land once had its own indigenous stories and big things may be seen as a pathetic attempt to replace, re-define and retell those stories by the interlopers now living on the land. "...Big things work allegorically, effacing, most notably, Aboriginal definitions of regional, tribal, spiritual, linguistic or other space" (Barcan 37). There is a sense in which big things are white trash barely obscuring black deaths (Nyoongah 12-14). But like a student's job-work over an old master's self portrait, big things invite us to peek through to the real totems of this land, totems enshrined in the creation myths of the indigenous dreaming. This is big things' contribution to the reconciliation process, to remind us of the fragile hold of white Australia on the land and to demand respect for the stories big things seek to displace. And that is the real big thing for white Australia in the reconciliation process, to accept these stories as our own so the land owns us. This is a much bigger leap than just saying sorry but in some strange way it has already commenced in the massive, mega-fauna that even now are rising from the land like the harbingers of a new dreamtime. A number of authors complain that, intentionally or otherwise, big things exclude indigenous flora and fauna and suggest that this points to a denial of history (Amdur 13, Barcan 36). But in recent years there has been a flood of big indigenous icons, many owned by indigenous corporations: big koalas, big kangaroos, big crocodiles, big bunyips and big barramundi. There is still the potential for indigenous artists to turn the joke around by creating big ancestral beings including rainbow serpents and the like.

A recent analysis of the “digital condition” of Norwegian higher education finds that a considerable number of teachers are willing to implement the use of technology in the classroom, but only to a limited degree. The study, which was carried out by the “Norway Opening University” (2006), found that there are no incentives for teachers in higher education to pursue and develop their use of technology. Research is still conceived of as far more rewarding than teaching. Another finding was that teachers and administrators lack knowledge about, and therefore have little belief in, the benefits of using technology. Younger teachers tend to use technology more than their older colleagues and the report suggests that they use technology more because they know more about the potentials of the technology. The report suggests that higher education institutions need to simplify the technology used and support academics more consistently. The report also suggests that such peer support will improve the chances of other academics finding the pedagogical use of ICT more legitimate and interesting. However, in the larger picture the report finds that academics have implemented technology to a significant degree. From being a marginal activity a decade and a half ago, it now influences the whole educational field in higher education. A different study from the US asks whether ICT has made any significant impact on teaching in American higher education. Instead of opening the pearly gates, the implementation of ICT and online learning has increased conservatism in American higher education, is one of the claims in the report “Thwarted innovation” (Zemsky and Massey 2004). The study suggests that implementing the use of technology does not necessarily lead to improved learning on behalf of the students. The authors rather suggest: “A number of people are coming to believe that the rapid introduction of course management tools has actually reduced elearning’s impact on the way most faculty teach. Blackboard and WebCT make it almost too easy for faculty to transfer their standard teaching materials to the Web” (Zemsky and Massy 2004). In a remarkable book, by James Cornford & Neil Pollock: Putting the university online. Information, technology and organizational change (2003), the authors posit a significantly more complex interpretation of why universities are slow actors in adopting ICT. The authors address the uncertainties that challenge the stability of conservative and “dinosaur-like” institutions such as higher education. They look at the “big picture” issue of what the use of ICT means for the university as an institution by focusing on technology as a process rather than as a black box. In doing this they consider the implications of the complex university functions of teaching, learning, organization and research for bringing the university “online” : how technology, social participation and human activity interact in creating the “new” realities of the university. In an interesting account of why efforts to make courses accessible and teachable online are often stalled, the authors note that the reasons are not simply “resistance”, "unstable technologies” or “costs”, but the sheer complexity of moving from on-campus to on-line. This process is so demanding that staff inevitably start calculating the cost-benefit dimensions of what Burbules and Callister jr. (2000) call “the promising risks and the risky promises” of change. This enterprise is influenced by the conflicting forces and ideas that engage the members of the academic community: enthusiasm, threats, marketing and resistance – all related to the interpretation of how ICT will affect and change the essential functions of the university. Simmons (2001) even argues that the educational technology threatens the very concept of Academic Freedom. In spite of a centurylong effort to upgrade teaching, research seems to survive as the most prestigious activity in U.S. universities, as it is in most European ones. In addition, the tendency is strong towards deeper polarization between research and teaching positions. Also, a rapid growth in the employment of part-time non-tenured teachers in the US poses a significant challenge to the traditional structure of employment. About one half of the faculty members in the U.S. are now part-time (Rice, Finkelstein, Hall & Schuster 2004). Most of these part time academics are doing teaching, and many of them are associated with online teaching and learning. Some have hopes and dreams about making repetitive work simpler and automated, like paying invoices. Handling teaching and learning is a totally different issue. If the case is that using technology will be outsourced to part-time personnel or restricted to learning centres etc. we shall miss the opportunity of addressing the more profound issues about technology, teaching and learning. Douglas Kellner (2001) argues that these issues are so serious that, much more than before, they “require a reformulation and expansion of the concept of critical or committed intellectual”. And there are numerous good reasons. If critical intellectuals do not commit themselves to investigating both risks and promises, other institutions, mainly commercial, will fill the gap. Higher education needs to become involved and set standards for the critical and reflective use of educational technology. Burbules and Callister jr. anticipate that ”Colleges and universities will change because of pressures from the outside as well as conscious decisions made from the inside, and technologies will be incorporated, in some ways and to some degree, in everything that colleges and universities try to do.” (ibid. p.7). The articles presented in this issue address such topics in many ways. Training university teachers to use online learning in a critical way is the topic Erika Løfstrøm and Anne Nevgi address in this issue. They suggest that letting university teachers study online would be a valuable exercise before letting them organize and run online learning themselves. Their paper reveals how teachers reflect on being students themselves when they learn how to study online. This is in a profound way an essential step in making colleagues critical about e-learning. Kristen Snyder coins the term “digital culture” as a key term in understanding the “information age”. She proposes that technology in human communication is a part of the communication act and therefore a part of the process of creating meaning. Her aim is to develop an awareness of the implications for behavior, norms and values, and how meaning making is integral to understanding the digital culture. She addresses in many respect the concerns voiced by Douglas Kellner (above). In developing a digital culture within the university, we can already trace significant differences between student cohorts. A general feeling is that mature students are less confident with ICT and its associated soft- and hardware than the youngest students arriving directly from upper secondary education. In a journal addressing lifelong learning, Håvard Skaar’s contribution suggests it is interesting to understand children’s learning processes from an early stage in the area of ICT. The article focuses on how boys and girls express themselves differently when using multimedia. Finally, Gunilla Jedeskog, who has followed the implementation of ICT in Swedish schools for more than two decades, makes an analysis of policy documents that guided this development. She addresses ownership of the process, and how it was interpreted. She finds that implementation was anything but a streamlined process, in many ways similar to the process in higher education, and that it changed focus over time. References:Burbules, N.

I miss the ferry to San Pietro, so after a long bus trip winding through the southern Sardinian rocky terrain past gum trees, shrubs, caper plants, and sheep, I take refuge from the rain in a bar at the port. While I order a beer and panini, the owner, a man in his early sixties, begins to chat asking me why I’m heading to the island. For the tuna, I say, to research cultural practices and changes surrounding the ancient tuna trap la tonnara, and for the Girotonno international tuna festival, which coincides with the migration of the Northern Bluefin Tuna and the harvest season. This year the slogan of the festival reads Dal Sulcis a Sushi ("From Sulcis to Sushi"), a sign of the diverse tastes to come. Tuna here is the best in the world, he exclaims, a sentiment I hear many times over whilst doing fieldwork in southern Italy. He excitedly gestures for me to follow. We walk into the kitchen and on a long steel bench sits a basin covered with cloth. He uncovers it, and proudly poised, waits for my reaction. A large pinkish-brown loin of cooked tuna sits in brine. I have never tasted tuna in this way, so to share in his enthusiasm I conjure my interest in the rich tuna gastronomy found in this area of Sardinia called Sulcis. I’m more familiar with the clean taste of sashimi or lightly seared tuna. As I later experience, traditional tuna preparations in San Pietro are far from this. The most notable characteristic is that the tuna is thoroughly cooked or the flesh or organs are preserved with salt by brining or drying. A tuna steak cooked in the oven is robust and more like meat from the land than the sea in its flavours, colour, and texture. This article is about taste: the taste of, and tastes for, tuna in a traditional fishing community. It is based on ethnographic fieldwork and is part of a wider inquiry into the place of tradition and culture in seafood sustainability discourses and practices. In this article I use the notion of a taste network to explore the relationship between macro forces—international markets, stock decline and marine regulations—and transformations within local cultures of tuna production and consumption. Taste networks frame the connections between taste in a gustatory sense, tastes as an aesthetic preference and tasting as a way of learning about and attuning to modes and meanings surrounding tuna. As Antoine Hennion asserts, taste is more than a connoisseurship of an object, taste represents a cultural activity that concerns a wide range of practices, exchanges and attachments. Elspeth Probyn suggests that taste “acts as a connector between history, place, things, and people” (65) and “can also come to form communities: local places that are entangled in the global” (62). Within this framework, taste moves away from Bourdieu’s notion of taste as a social distinction towards an understanding of taste as created through a network of entities—social, biological, technological, and so forth. It turns attention to the mundane activities and objects of tuna production and consumption, the components of a taste network, and the everyday spaces where tradition and transformation are negotiated. For taste to change requires a transformation of the network (or components of that network) that bring such tastes into existence. These networks and their elements form the very meaning, matter, and moments of tradition and culture. As Hennion reminds us through his idea of “reservoir(s) of difference” (100), there are a range of diverse tastes that can materialise from the interactions of humans with objects, in this case tuna. Yet, taste networks can also be rendered obsolete. When a highly valued and endangered species like Bluefin is at the centre of such networks, there are material, ethical, and even political limitations to some tastes. In a study that follows three scientists as they attempt to address scallop decline in Brest and St Brieuc Bay, Michael Callon advocates for “the abandonment of all prior distinction between the natural and the social” (1). He draws attention to networks of actors and significant moments, rather than pre-existing categories, to figure the contours of power. This approach is particularly useful for social research that involves science, technology and the “natural” world. In my own research in San Pietro, the list of human and non-human actors is long and spans the local to the global: Bluefin (in its various meanings and as an entity with its own agency), tonnara owners, fishermen, technologies, fish shops and restaurants, scientific observers, policy (local, regional, national, European and international), university researchers, the sea, weather, community members, Japanese and Spanish buyers, and markets. Local discourses surrounding tuna and taste articulate human and non-human entanglements in quite particular ways. In San Pietro, as with much of Italy, notions of place, environment, identity, quality, and authenticity are central to the culture of tuna production and consumption. Food products are connected to place through ecological, cultural and technological dimensions. In Morgan, Marsden, and Murdoch’s terms this frames food and tastes in relation to a spatial dimension (its place of origin), a social dimension (its methods of production and distribution), and a cultural dimension (its perceived qualities and reputation). The place name labelling of canned tuna from San Pietro is an example of a product that represents the notion of provenance. The practice of protecting traditional products is well established in Italy through appellation programs, much like the practice of protecting terroir products in France. It is no wonder that the eco-gastronomic movement Slow Food developed in Italy as a movement to protect traditional foods, production methods, and biodiversity. Such discourses and movements like Slow Food create local/global frameworks and develop in relation to the phenomenon and ideas like globalisation, industrialization, and homogenisation. This study is based on ethnographic fieldwork in San Pietro over the 2013 tuna season. This included interviews with some thirty participants (fishers, shop keepers, locals, restaurateurs, and tonnara owners), secondary research into international markets, marine regulations, and environmental movements, and—of course—a gustatory experience of tuna. Walking down the main street the traditions of the tonnara and tuna are palpable. On a first impression there’s something about the streets and piazzas that is akin to Zukin’s notion of “vernacular spaces”, “sources of identity and belonging, affective qualities that the idea of intangible culture expresses, refines and sustains” (282). At the centre is the tonnara, which refers to the trap (a labyrinth of underwater nets) as well as the technique of tuna fishing and land based processing activities. For centuries, tuna and the tonnara have been at the centre of community life, providing employment, food security, and trade opportunities, and generating a wealth of ecological knowledge, a rich gastronomy based on preserved tuna, and cultural traditions like the famous harvest ritual la mattanza (the massacre). Just about every organ is preserved by salting and drying. The most common is the female ovary sac, which becomes bottarga. Grated onto pasta it has a strong metallic offal flavour combined with the salty tang of the sea. There is also the male equivalent lusciami, a softer consistency and flavour, as well as dried heart and lungs. There is canned tuna, a continuation of the tradition of brining and barrelling, but these are no ordinary cans. Each part of the tuna is divided into parts corresponding loosely to anatomy but more closely to quality based on textures, colour, and taste. There is the ventresca from the belly, the most prized cut because of its high fat content. Canned in olive oil or brine, a single can of this cut sells for around 30 Euros. Both the canned variety or freshly grilled ventresca is a sumptuous experience, soft and rich. Change is not new to San Pietro. In the long history of the tonnara there have been numerous transformations resulting from trade, occupation, and dominant economic systems. As Stefano Longo describes, with the development of capitalism and industrialization, the socio-economic structure of the tonnara changed and there was a dramatic decline in tonnare (plural) throughout the 1800s. The tonnare also went through different phases of ownership. In 1587 King Philip II formally established the Sardinian tonnare (Emery). Phillip IV then sold a tonnara to a Genovese man in 1654 and, from the late 18th century until today, the tonnara has remained in the Greco family from Genova. There were also changes to fishing and preservation technologies, such as the replacement of barrels after the invention of the can in the early 1800s, and innovations to recipes, as for example in the addition of olive oil. Yet, compared to recent changes, the process of harvesting, breaking down and sorting flesh and organs, and preserving tuna, has remained relatively stable. The locus of change in recent years concerns the harvest, the mattanza. For locals this process seems to be framed with concepts of before, and after, the Japanese arrived on the island. Owner Giuliano Greco, a man in his early fifties who took over the management of the tonnara from his father when it reopened in the late 1990s, describes these changes: We have two ages—before the Japanese and after. Before the Japanese, yes, the tuna was damaged. It was very violent in the mattanza. In the age before the pollution, there was a crew of 120 people divided in a little team named the stellati. The more expert and more important at the centre of the boat, the others at the side because at the centre there was more tuna. When there was mattanza it was like a race, a game, because if they caught more tuna they had more entrails, which was good money for them, because before, part of the wage was in nature, part of the tuna, and for this game the tuna was damaged because they opened it with a knife, the heart, the eggs etc. And for this method it was very violent because they wanted to get the tuna entrails first. The tuna remained on the boat without ice, with blood everywhere. The tonnara operated within clear social hierarchies made up of tonnarotti (tuna fishermen) under the guidance of the Rais (captain of tonnara) whose skills, charisma and knowledge set him apart. The Rais liaised with the tonnarotti, the owners, and the local community, recruiting men and women to augment the workforce in the mattanza period. Goliardo Rivano, a tonnarotto (singular) since 1999 recalls “all the town would be called on for the mattanza. Not only men but women too would work in the cannery, cutting, cleaning, and canning the tuna.” The mattanza was the starting point of supply and consumption networks. From the mattanza the tuna was broken down, the flesh boiled and brined for local and foreign markets, and the organs salted and dried for the (mainly) local market. Part of the land-based activities of tonnarotti involved cleaning, salting, pressing and drying the organs, which supplemented their wage. As Giuliano described, the mattanza was a bloody affair because of the practice of retrieving the organs; but since the tuna was boiled and then preserved in brine, it was not important whether the flesh was damaged. At the end of the 1970s the tonnara closed. According to locals and reportage, pollution from a nearby factory had caused a drastic drop in tuna. It remained closed until the mid 1990s when Japanese buyers came to inquire about tuna from the trap. Global tastes for tuna had changed during the time the tonnara was closed. An increase in western appetites for sushi had been growing since the early 1970s (Bestore). As Theadore Bestore describes in detail, this coincided with a significant transformation of the Japanese fishing industry’s international role. In the 1980s, the Japanese government began to restructure its fleets in response to restricted access to overseas fishing grounds, which the declaration of Excusive Economic Zones enforced (Barclay and Koh). At this time, Japan turned to foreign suppliers for tuna (Bestore). Kate Barclay and Sun-Hui Koh describe how quantity was no longer a national food security issue like it had been in post war Japan and “consumers started to demand high-quality high-value products” (145). In the late 1990s, the Greco family reopened the tonnara and the majority of the tuna went to Japan leaving a smaller portion for the business of canning. The way mattanza was practiced underwent profound changes and particular notions of quality emerged. This was also the beginning of new relationships and a widening of the taste network to include international stakeholders: Japanese buyers and markets became part of the network. Giuliano refers to the period as the “Japanese Age”. A temporal framing that is iterated by restaurant and fish shop owners who talk about a time when Japanese began to come to the island and have the first pick of the tuna. Giuliano recalls “there was still blood but there was not the system of opening tuna, in total, like before. Now the tuna is opened on the land. The only operation we do on the boat is blooding and chilling.” Here he references the Japanese technique of ikejime. Over several years the technicians taught Giuliano and some of the crew about killing the tuna faster and bleeding it to maintain colour and freshness. New notions of quality and taste for raw or lightly cooked tuna entered San Pietro. According to Rais Luigi “the tuna is of higher quality, because we treat it in a particular way, with ice.” Giuliano describes the importance of quality. “Before they used the stellati and it took five people, each one with a harpoon to haul the tuna. Now they only use one hook, in the mouth and use a chain, by hand. On board there is bleeding, and there is blood, but now we must keep the quality of the meat at its best.” In addition to the influence of Japanese tastes, the international Girotonno tuna festival had its inauguration in 2003, and, along with growing tourism, brought cosmopolitan and international tastes to San Pietro. The impact of a global taste for tuna has had devastating effects on their biomass. The international response to the sharp decline was the expansion of the role of inter-governmental monitoring bodies like International Commission for the Conservation of Atlantic Tunas (ICCAT), the introduction of quotas, and an increase in the presence of marine authorities on fleets, scientific research and environmental campaigns. In San Pietro, international relationships further widened and so did the configuration of taste networks, this time to include marine regulators, a quota on Bluefin, a Spanish company, and tuna ranches in Malta. The mattanza again was at the centre of change and became a point of contention within the community. This time because as a practice it is endangered, occurring only once or twice a year, “for the sake of tradition, culture” as Giuliano stated. The harvest now takes place in ranches in Malta because for the last three years the Greco family have supplied the tonnara’s entire quota (excluding tuna from mattanza or those that die in the net) to a major Spanish seafood company Riccardo Fuentes e Hijos, which transports them live to Malta where they are fattened and slaughtered, predominantly for a Japanese market. The majority of tuna now leave the island whole, which has profoundly transformed the distribution networks and local taste culture, and mainly the production and trade in tuna organs and canned tuna. In 2012, ICCAT and the European Union further tightened the quotas, which along with competition with industrial fisheries for both quota and markets, has placed enormous pressure on the tonnara. In 2013, it was allocated a quota that was well under what is financially sustainable. Add to the mix the additional expense of financing the obligatory scientific observers, and the tonnara has had to modify its operations. In the last few years there has been a growing antagonism between marine regulations, global markets, and traditional practices. This is exemplified in the limitations to the tuna organ tradition. It is now more common to find dried tuna organs in vacuum packs from Sicily rather than local products. As the restaurateur Secondo Borghero of Tonno della Corsa says “the tonnara made a choice to sell the live tuna to the Spanish. It’s a big problem. The tuna is not just the flesh but also the interior—the stomach, the heart, the eggs—and now we don’t have the quantity of these and the quality around is also not great.” In addition, even though preserved organs are available for consumption, local preserving activities have almost ceased along with supplementary income. The social structures and the types of actors that are a part of the tonnara have also changed. New kinds of relationships, bodies, and knowledge are situated side by side because of the mandate that there be scientific observers present at certain moments in the season. In addition, there are coast guards and, at various stages of the season, university staff contracted by ICCAT take samples and tag the tuna to generate data. The changes have also introduced new types of knowledge, activities, and institutional affiliations based on scientific ideas and discourses of marine biology, conservation, and sustainability. These are applied through marine management activities and regimes like quotas and administered through state and global institutions. This is not to say that the knowledge informing the Rais’s decisions has been done away with but as Gisli Palsson has previously argued, there is a new knowledge hierarchy, which places a significant focus on the notion of expert knowledge. This has the potential to create unequal power dynamics between the marine scientists and the fishers. Today in San Pietro tuna tastes are diverse. Tuna is delicate, smooth, and rich ventresca, raw tartare clean on the palate, novel at the Girotono, hearty tuna al forno, and salty dry bottarga. Tasting tuna in San Pietro offers a material and affective starting point to follow the socio-cultural, political, and ecological contours and contentions that are part of tuna traditions and their transformations. By thinking of gustatory and aesthetic tastes as part of wider taste networks, which involve human and non-human entities, we can begin to unpack and detail better what these changes encompass and figure forms and moments of power and agency. At the centre of tastes and transformation in San Pietro are the tonnara and the mattanza. Although in its long existence the tonnara has endured many changes, those in the past 15 years are unprecedented. Several major global events have provided conditions for change and widened the network from its once mainly local setting to its current global span. First, Japanese and global tastes set a demand for tuna and introduced different tuna production and preparation techniques and new styles of serving tuna raw or lightly cooked tuna. Later, the decline of Bluefin stocks and the increasing involvement of European and international monitoring bodies introduced catch limitations along with new processes and types of knowledge and authorities. Coinciding with this was the development of relationships with middle companies, which again introduced new techniques and technologies, namely the gabbie (cage) and ranches, to the taste network. In the cultural setting of Italy where the conservation of tradition is of particular importance, as I have explained earlier through the notion of provenance, the management of a highly regulated endangered marine species is a complex project that causes much conflict. Because of the dire state of the stocks and continual rise in global demand, solutions are complex. Yet it would seem useful to recognise that tuna tastes are situated within a network of knowledge, know-how, technology, and practices that are not simple modes of production and consumption but also ways of stewarding the sea and its species.

Practically any good story follows certain narrative conventions in order to hold its readers' attention and leave them with a feeling of satisfaction -- this goes for fictional tales as well as for many news reports (we do tend to call them 'news stories', after all), for idle gossip as well as for academic papers. In the Western tradition of storytelling, it's customary to start with the exposition, build up to major events, and end with some form of narrative closure. Indeed, audience members will feel disturbed if there is no sense of closure at the end -- their desire for closure is a powerful one. From this brief description of narrative patterns it is also clear that such narratives depend crucially on linear progression through the story in order to work -- there may be flashbacks and flashforwards, but very few stories, it seems, could get away with beginning with their point of closure, and work back to the exposition. Closure, as the word suggests, closes the story, and once reached, the audience is left with the feeling of now knowing the whole story, of having all the pieces necessary to understand its events. To understand how important the desire to reach this point is to the audience, just observe the discussions of holes in the plot which people have when they're leaving a cinema: they're trying to reach a better sense of closure than was afforded them by the movie itself. In linearly progressing media, this seems, if you'll pardon the pun, straightforward. Readers know when they've finished an article or a book, viewers know when a movie or a broadcast is over, and they'll be able to assess then if they've reached sufficient closure -- if their desires have been fulfilled. On the World Wide Web, this is much more difficult: "once we have it in our hands, the whole of a book is accessible to us readers. However, in front of an electronic read-only hypertext document we are at the mercy of the author since we will only be able to activate the links which the author has provided" (McKnight et al. 119). In many cases, it's not even clear whether we've reached the end of the text already: just where does a Website end? Does the question even make sense? Consider the following example, reported by Larry Friedlander: I watched visitors explore an interactive program in a museum, one that contained a vast amount of material -- pictures, film, historic explanations, models, simulations. I was impressed by the range of subject matter and by the ambitiousness and polish of the presentation. ... But to my surprise, as I watched visitors going down one pathway after another, I noticed a certain dispirited glaze spread over their faces. They seemed to lose interest quite quickly and, in fact, soon stopped their explorations. (163) Part of the problem here may just have been the location of the programme, of course -- when you're out in public, you might just not have the time to browse as extensively as you could from your computer at home. But there are other explanations, too: the sheer amount of options for exploration may have been overwhelming -- there may not have been any apparent purpose to aim for, any closure to arrive at. This is a problem inherent in hypertext, particularly in networked systems like the Web: it "changes our conception of an ending. Different readers can choose not only to end the text at different points but also to add to and extend it. In hypertext there is no final version, and therefore no last word: a new idea or reinterpretation is always possible. ... By privileging intertextuality, hypertext provides a large number of points to which other texts can attach themselves" (Snyder 57). In other words, there will always be more out there than any reader could possibly explore, since new documents are constantly being added. There is no ending if a text is constantly extended. (In print media this problem appears only to a far more limited extent: there, intertextuality is mostly implicit, and even though new articles may constantly be added -- 'linked', if you will -- to a discourse, due to the medium's physical nature they're still very much separate entities, while Web links make intertextuality explicit and directly connect texts.) Does this mark the end of closure, then? Adding to the problem is the fact that it's not even possible to know how much of the hypertextual information available is still left unexplored, since there is no universal register of all the information available on the Web -- "the extent of hypertext is unknowable because it lacks clear boundaries and is often multi-authored" (Snyder 19). While reading a book you can check how many more pages you've got to go, but on the Web this is not an option. Our traditions of information transmission create this desire for closure, but the inherent nature of the medium prevents us from ever satisfying it. Barrett waxes lyrical in describing this dilemma: contexts presented online are often too limited for what we really want: an environment that delivers objects of desire -- to know more, see more, learn more, express more. We fear being caught in Medusa's gaze, of being transfixed before the end is reached; yet we want the head of Medusa safely on our shield to freeze the bitstream, the fleeting imagery, the unstoppable textualisations. We want, not the dead object, but the living body in its connections to its world, connections that sustain it, give it meaning. (xiv-v) We want nothing less, that is, than closure without closing: we desire the knowledge we need, and the feeling that that knowledge is sufficient to really know about a topic, but we don't want to devalue that knowledge in the same process by removing it from its context and reducing it to trivial truisms. We want the networked knowledge base that the Web is able to offer, but we don't want to feel overwhelmed by the unfathomable dimensions of that network. This is increasingly difficult the more knowledge is included in that network -- "with the growth of knowledge comes decreasing certainty. The confidence that went with objectivity must give way to the insecurity that comes from knowing that all is relative" (Smith 206). The fact that 'all is relative' is one which predates the Net, of course, and it isn't the Internet or the World Wide Web that has destroyed objectivity -- objectivity has always been an illusion, no matter how strongly journalists or scientists have at times laid claims ot it. Internet-based media have simply stripped away more of the pretences, and laid bare the subjective nature of all information; in the process, they have also uncovered the fact that the desire for closure must ultimately remain unfulfilled in any sufficiently non-trivial case. Nonetheless, the early history of the Web has seen attempts to connect all the information available (LEO, one of the first major German Internet resource centres, for example, took its initials from its mission to 'Link Everything Online') -- but as the amount of information on the Net exploded, more and more editorial choices of what to include and what to leave out had to be made, so that now even search engines like Yahoo! and Altavista quite clearly and openly offer only a selection of what they consider useful sites on the Web. Web browsers still hoping to find everything on a certain topic would be well-advised to check with all major search engines, as well as important resource centres in the specific field. The average Web user would probably be happy with picking the search engine, Web directory or Web ring they find easiest to use, and sticking with it. The multitude of available options here actually shows one strength of the Internet and similar networks -- "the computer permits many [organisational] structures to coexist in the same electronic text: tree structures, circles, and lines can cross and recross without obstructing one another. The encyclopedic impulse to organise can run riot in this new technology of writing" (Bolter 95). Still, this multitude of options is also likely to confuse some users: in particular, "novices do not know in which order they need to read the material or how much they should read. They don't know what they don't know. Therefore learners might be sidetracked into some obscure corner of the information space instead or covering the important basic information" (Nielsen 190). They're like first-time visitors to a library -- but this library has constantly shifting aisles, more or less well-known pathways into specialty collections, fiercely competing groups of librarians, and it extends almost infinitely. Of course, the design of the available search and information tools plays an important role here, too -- far more than it is possible to explore at this point. Gay makes the general observation that "visual interfaces and navigational tools that allow quick browsing of information layout and database components are more effective at locating information ... than traditional index or text-based search tools. However, it should be noted that users are less secure in their findings. Users feel that they have not conducted complete searches when they use visual tools and interfaces" (185). Such technical difficulties (especially for novices) will slow take-up of and low satisfaction with the medium (and many negative views of the Web can probably be traced to this dissatisfaction with the result of searches -- in other words, to a lack of satisfaction of the desire for closure); while many novices eventually overcome their initial confusion and become more Web-savvy, others might disregard the medium as unsuitable for their needs. At the other extreme of the scale, the inherent lack for closure, in combination with the societally deeply ingrained desire for it, may also be a strong contributing factor for another negative phenomenon associated with the Internet: that of Net users becoming Net junkies, who spend every available moment online. Where the desire to know, to get to the bottom (or more to the point: to the end) of a topic, becomes overwhelming, and where the fundamental unattainability of this goal remains unrealised, the step to an obsession with finding information seems a small one; indeed, the neverending search for that piece of knowledge surpassing all previously found ones seems to have obvious similarities to drug addiction with its search for the high to better all previous highs. And most likely, the addiction is only heightened by the knowledge that on the Web, new pieces of information are constantly being added -- an endless, and largely free, supply of drugs... There is no easy solution to this problem -- in the end, it is up to the user to avoid becoming an addict, and to keep in mind that there is no such thing as total knowledge. Web designers and content providers can help, though: "there are ways of orienting the reader in an electronic document, but in any true hypertext the ending must remain tentative. An electronic text never needs to end" (Bolter 87). As Tennant & Heilmeier elaborate, "the coming ease-of-use problem is one of developing transparent complexity -- of revealing the limits and the extent of vast coverage to users, and showing how the many known techniques for putting it all together can be used most effectively -- of complexity that reveals itself as powerful simplicity" (122). We have been seeing, therefore, the emergence of a new class of Websites: resource centres which help their visitors to understand a certain topic and view it from all possible angles, which point them in the direction of further information on- and off-site, and which give them an indication of how much they need to know to understand the topic to a certain degree. In this, they must ideally be very transparent, as Tennant & Heilmeier point out -- having accepted that there is no such thing as objectivity, it is necessary for these sites to point out that their offered insight into the field is only one of many possible approaches, and that their presented choice of information is based on subjective editorial decisions. They may present preferred readings, but they must indicate that these readings are open for debate. They may help satisfy some of their readers' desire for closure, but they must at the same time point out that they do so by presenting a temporary ending beyond which a more general story continues. If, as suggested above, closure crucially depends on a linear mode of presentation, such sites in their arguments help trace one linear route through the network of knowledge available online; they impose a linear from-us-to-you model of transmission on the normally unordered many-to-many structure of the Net. In the face of much doomsaying about the broadcast media, then, here is one possible future for these linear transmission media, and it's no surprise that such Internet 'push' broad- or narrowcasting is a growth area of the Net -- simply put, it serves the apparent need of users to be told stories, to have their desire for closure satisfied through clear narrative progressions from exposition through development to end. (This isn't 'push' as such, really: it's more a kind of 'push on demand'.) But at the same time, this won't mean the end of the unstructured, networked information that the Web offers: even such linear media ultimately build on that networked pool of knowledge. The Internet has simply made this pool public -- passively as well as actively accessible to everybody. Now, however, Web designers (and this includes each and every one of us, ultimately) must work "with the users foremost in mind, making sure that at every point there is a clear, simple and focussed experience that hooks them into the welter of information presented" (Friedlander 164); they must play to the desire for closure. (As with any preferred reading, however, there is also a danger that that closure is premature, and that the users' process or meaning-making is contained and stifled rather than aided.) To return briefly to Friedlander's experience with the interactive museum exhibit: he draws the conclusion that visitors were simply overwhelmed by the sheer mass of information and were reluctant to continue accumulating facts without a guiding purpose, without some sense of how or why they could use all this material. The technology that delivers immense bundles of data does not simultaneously deliver a reason for accumulating so much information, nor a way for the user to order and make sense of it. That is the designer's task. The pressing challenge of multimedia design is to transform information into usable and useful knowledge. (163) Perhaps this transformation is exactly what is at the heart of fulfilling the desire for closure: we feel satisfied when we feel we know something, have learnt something from a presentation of information (no matter if it's a news report or a fictional story). Nonetheless, this satisfaction must of necessity remain intermediate -- there is always much more still to be discovered. "From the hypertext viewpoint knowledge is infinite: we can never know the whole extent of it but only have a perspective on it. ... Life is in real-time and we are forced to be selective, we decide that this much constitutes one node and only these links are worth representing" (Beardon & Worden 69). This is not inherently different from processes in other media, where bandwidth limitations may even force much stricter gatekeeping regiments, but as in many cases the Internet brings these processes out into the open, exposes their workings and stresses the fundamental subjectivity of information. Users of hypertext (as indeed users of any medium) must be aware of this: "readers themselves participate in the organisation of the encyclopedia. They are not limited to the references created by the editors, since at any point they can initiate a search for a word or phrase that takes them to another article. They might also make their own explicit references (hypertextual links) for their own purposes ... . It is always a short step from electronic reading to electronic writing, from determining the order of texts to altering their structure" (Bolter 95). Significantly, too, it is this potential for wide public participation which has made the Internet into the medium of the day, and led to the World Wide Web's exponential growth; as Bolter describes, "today we cannot hope for permanence and for general agreement on the order of things -- in encyclopedias any more than in politics and the arts. What we have instead is a view of knowledge as collections of (verbal and visual) ideas that can arrange themselves into a kaleidoscope of hierarchical and associative patterns -- each pattern meeting the needs of one class of readers on one occasion" (97). To those searching for some meaningful 'universal truth', this will sound defeatist, but ultimately it is closer to realism -- one person's universal truth is another one's escapist phantasy, after all. This doesn't keep most of us from hoping and searching for that deeper insight, however -- and from the preceding discussion, it seems likely that in this we are driven by the desire for closure that has been imprinted in us so deeply by the multitudes of narrative structures we encounter each day. It's no surprise, then, that, as Barrett writes, "the virtual environment is a place of longing. Cyberspace is an odyssey without telos, and therefore without meaning. ... Yet cyberspace is also the theatre of operations for the reconstruction of the lost body of knowledge, or, perhaps more correctly, not the reconstruction, but the always primary construction of a body of knowing. Thought and language in a virtual environment seek a higher synthesis, a re-imagining of an idea in the context of its truth" (xvi). And so we search on, following that by definition end-less quest to satisfy our desire for closure, and sticking largely to the narrative structures handed down to us through the generations. This article is no exception, of course -- but while you may gain some sense of closure from it, it is inevitable that there is a deeper feeling of a lack of closure, too, as the article takes its place in a wider hypertextual context, where so much more is still left unexplored: other articles in this issue, other issues of M/C, and further journals and Websites adding to the debate. Remember this, then: you decide when and where to stop. References Barrett, Edward, and Marie Redmont, eds. Contextual Media: Multimedia and Interpretation. Cambridge, Mass.: MIT P, 1995.

Introduction As social-distancing mandates in response to COVID-19 restricted in-person data collection methods such as participant observation and interviews, researchers turned to socially distant methods such as interviewing via video-conferencing technology (Lobe et al.). These were not new tools nor methods, but the pandemic muted any bias towards face-to-face data collection methods. Exemplified in crowd-sourced documents such as Doing Fieldwork in a Pandemic, researchers were encouraged to pivot to digital methods as a means of fulfilling research objectives, “specifically, ideas for avoiding in-person interactions by using mediated forms that will achieve similar ends” (Lupton). The benefits of digital methods for expanding participant cohorts and scope of research have been touted long before 2020 and COVID-19, and, as noted by Murthy, are “compelling” (“Emergent” 172). Research conducted by digital methods can expect to reap benefits such as “global datasets/respondents” and “new modalities for involving respondents” (Murthy, “Emergent” 172). The pivot to digital methods is not in and of itself an issue. What concerns us is that in the dialogues about shifting to digital methods during COVID-19, there does not yet appear to have been a critical consideration of how participant samples and collected data will be impacted upon or skewed towards recording the experiences of advantaged cohorts. Existing literature focusses on the time-saving benefits for the researcher, reduction of travel costs (Fujii), the minimal costs for users of specific platforms – e.g. Skype –, and presumes ubiquity of device access for participants (Cater). We found no discussion on data costs of accessing such services being potential barriers to participation in research, although Deakin and Wakefield did share our concern that: Online interviews may ... mean that some participants are excluded due to the need to have technological competence required to participate, obtain software and to maintain Internet connection for the duration of the discussion. In this sense, access to certain groups may be a problem and may lead to issues of representativeness. (605) We write this as a provocation to our colleagues conducting research at this time to consider the cultural and material capital of their participants and how that capital enables them to participate in digitally-mediated data gathering practices, or not, and to what extent. Despite highlighting the potential benefits of digital methods within a methodological tool kit, Murthy previously cautioned against the implications posed by digital exclusion, noting that “the drawback of these research options is that membership of these communities is inherently restricted to the digital ‘haves’ ... rather than the ‘have nots’” (“Digital” 845). In this article, we argue that while tools such as Zoom have indeed enabled fieldwork to continue despite COVID disruptions, this shift to online platforms has important and under-acknowledged implications for who is and is not able to participate in research. In making this argument, we draw on examples from the Connected Students project, a study of digital inclusion that commenced just as COVID-19 restrictions came into effect in the Australian state of Victoria at the start of 2020. We draw on the experiences of these households to illustrate the barriers that such cohorts face when participating in online research. We begin by providing details about the Connected Students project and then contextualising it through a discussion of research on digital inclusion. We then outline three areas in which households would have experienced (or still do experience) difficulties participating in online research: data, devices, and skills. We use these findings to highlight the barriers that disadvantaged groups may face when engaging in data collection activities over Zoom and question how this is impacting on who is and is not being included in research during COVID-19. The Connected Students Program The Connected Students program was conducted in Shepparton, a regional city located 180km north of Melbourne. The town itself has a population of around 30,000, while the Greater Shepparton region comprises around 64,000 residents. Shepparton was chosen as the program’s site because it is characterised by a unique combination of low-income and low levels of digital inclusion. First, Shepparton ranks in the lowest interval for the Australian Bureau of Statistics’ Socio-Economic Indexes for Areas (SEIFA) and the Index of Relative Socioeconomic Advantage and Disadvantage (IRSAD), as reported in 2016 (Australian Bureau of Statistics, “Census”; Australian Bureau of Statistics, “Index”). Although Shepparton has a strong agricultural and horticultural industry with a number of food-based manufacturing companies in the area, including fruit canneries, dairies, and food processing plants, the town has high levels of long-term and intergenerational unemployment and jobless families. Second, Shepparton is in a regional area that ranks in the lowest interval for the Australian Digital Inclusion Index (Thomas et al.), which measures digital inclusion across dimensions of access, ability, and affordability. Funded by Telstra, Australia’s largest telecommunications provider, and delivered in partnership with Greater Shepparton Secondary College (GSSC), the Connected Students program provided low-income households with a laptop and an unlimited broadband Internet connection for up to two years. Households were recruited to the project via GSSC. To be eligible, households needed to hold a health care card and have at least one child attending the school in year 10, 11, or 12. Both the student and a caregiver were required to participate in the project to be eligible. Additional household members were invited to take part in the research, but were not required to. (See Kennedy & Holcombe-James; and Kennedy et al., "Connected Students", for further details regarding household demographics.) The Australian Digital Inclusion Index identifies that affordability is a significant barrier to digital inclusion in Australia (Thomas et al.). The project’s objective was to measure how removing affordability barriers to accessing connectivity for households impacts on digital inclusion. By providing participating households with a free unlimited broadband internet connection for the duration of the research, the project removed the costs associated with digital access. Access alone is not enough to resolve the digital exclusion confronted by these low-income households. Digital exclusion in these instances is not derived simply from the cost of Internet access, but from the cost of digital devices. As a result, these households typically lacked sufficient digital devices. Each household was therefore provided both a high speed Internet connection, and a brand new laptop with built-in camera, microphone, and speakers (a standard tool kit for video conferencing). Data collection for the Connected Students project was intended to be conducted face-to-face. We had planned in-person observations including semi-structured interviews with household members conducted at three intervals throughout the project’s duration (beginning, middle, and end), and technology tours of each home to spatially and socially map device locations and uses (Kennedy et al., Digital Domesticity). As we readied to make our first research trip to commence the study, COVID-19 was wreaking havoc. It quickly became apparent we would not be travelling to work, much less travelling around the state. We thus pivoted to digital methods, with all our data collection shifting online to interviews conducted via digital platforms such as Zoom and Microsoft Teams. While the pivot to digital methods saved travel hours, allowing us to scale up the number of households we planned to interview, it also demonstrated unexpected aspects of our participants’ lived experiences of digital exclusion. In this article, we draw on our first round of interviews which were conducted with 35 households over Zoom or Microsoft Teams during lockdown. The practice of conducting these interviews reveals insights into the barriers that households faced to digital research participation. In describing these experiences, we use pseudonyms for individual participants and refer to households using the pseudonym for the student participant from that household. Why Does Digital Inclusion Matter? Digital inclusion is broadly defined as universal access to the technologies necessary to participate in social and civic life (Helsper; Livingstone and Helsper). Although recent years have seen an increase in the number of connected households and devices (Thomas et al., “2020”), digital inclusion remains uneven. As elsewhere, digital disadvantage in the Australian context falls along geographic and socioeconomic lines (Alam and Imran; Atkinson et al.; Blanchard et al.; Rennie et al.). Digitally excluded population groups typically experience some combination of education, employment, income, social, and mental health hardship; their predicament is compounded by a myriad of important services moving online, from utility payments, to social services, to job seeking platforms (Australian Council of Social Service; Chen; Commonwealth Ombudsman). In addition to challenges in using essential services, digitally excluded Australians also miss out on the social and cultural benefits of Internet use (Ragnedda and Ruiu). Digital inclusion – and the affordability of digital access – should thus be a key concern for researchers looking to apply online methods. Households in the lowest income quintile spend 6.2% of their disposable income on telecommunications services, almost three times more than wealthier households (Ogle). Those in the lowest income quintile pay a “poverty premium” for their data, almost five times more per unit of data than those in the highest income quintile (Ogle and Musolino). As evidenced by the Australian Digital Inclusion Index, this is driven in part by a higher reliance on mobile-only access (Thomas et al., “2020”). Low-income households are more likely to access critical education, business, and government services through mobile data rather than fixed broadband data (Thomas et al., “2020”). For low-income households, digital participation is the top expense after housing, food, and transport, and is higher than domestic energy costs (Ogle). In the pursuit of responsible and ethical research, we caution against assuming research participants are able to bear the brunt of access costs in terms of having a suitable device, expending their own data resources, and having adequate skills to be able to complete the activity without undue stress. We draw examples from the Connected Students project to support this argument below. Findings: Barriers to Research Participation for Digitally Excluded Households If the Connected Students program had not provided participating households with a technology kit, their preexisting conditions of digital exclusion would have limited their research participation in three key ways. First, households with limited Internet access (particularly those reliant on mobile-only connectivity, and who have a few gigabytes of data per month) would have struggled to provide the data needed for video conferencing. Second, households would have struggled to participate due to a lack of adequate devices. Third, and critically, although the Connected Students technology kit provided households with the data and devices required to participate in the digital ethnography, this did not necessarily resolve the skills gaps that our households confronted. Data Prior to receiving the Connected Students technology kit, many households in our sample had limited modes of connectivity and access to data. For households with comparatively less or lower quality access to data, digital participation – whether for the research discussed here, or in contemporary life – came with very real costs. This was especially the case for households that did not have a home Internet connection and instead relied solely on mobile data. For these households, who carefully managed their data to avoid running out, participating in research through extended video conferences would have been impossible unless adequate financial reimbursement was offered. Households with very limited Internet access used a range of practices to manage and extend their data access by shifting internet costs away from the household budget. This often involved making use of free public Wi-Fi or library internet services. Ellie’s household, for instance, spent their weekends at the public library so that she and her sister could complete their homework. While laborious, these strategies worked well for the families in everyday life. However, they would have been highly unsuitable for participating in research, particularly during the pandemic. On the most obvious level, the expectations of library use – if not silent, then certainly quiet – would have prohibited a successful interview. Further, during COVID-19 lockdowns, public libraries (and other places that provide public Internet) became inaccessible for significant periods of time. Lastly, for some research designs, the location of participants is important even when participation is occurring online. In the case of our own project, the house itself as the site of the interview was critical as our research sought to understand how the layout and materiality of the home impacts on experiences of digital inclusion. We asked participants to guide us around their home, showing where technologies and social activities are colocated. In using the data provided by the Connected Students technology kit, households with limited Internet were able to conduct interviews within their households. For these families, participating in online research would have been near impossible without the Connected Students Internet. Devices Even with adequate Internet connections, many households would have struggled to participate due to a lack of suitable devices. Laptops, which generally provide the best video conferencing experience, were seen as prohibitively expensive for many families. As a result, many families did not have a laptop or were making do with a laptop that was excessively slow, unreliable, and/or had very limited functions. Desktop computers were rare and generally outdated to the extent that they were not able to support video conferencing. One parent, Melissa, described their barely-functioning desktop as “like part of the furniture more than a computer”. Had the Connected Students program not provided a new laptop with video and audio capabilities, participation in video interviews would have been difficult. This is highlighted by the challenges students in these households faced in completing online schooling prior to receiving the Connected Students kit. A participating student, Mallory, for example, explained she had previously not had a laptop, reliant only on her phone and an old iPad: Interviewer: Were you able to do all your homework on those, or was it sometimes tricky?Mallory: Sometimes it was tricky, especially if they wanted to do a call or something ... . Then it got a bit hard because then I would use up all my data, and then didn’t have much left.Interviewer: Yeah. Right.Julia (Parent): ... But as far as schoolwork, it’s hard to do everything on an iPad. A laptop or a computer is obviously easier to manoeuvre around for different things. This example raises several common issues that would likely present barriers to research participation. First, Mallory’s household did not have a laptop before being provided with one through the Connected Students program. Second, while her household did prioritise purchasing tablets and smartphones, which could be used for video conferencing, these were more difficult to navigate for certain tasks and used up mobile data which, as noted above, was often a limited resource. Lastly, it is worth noting that in households which did already own a functioning laptop, it was often shared between several household members. As one parent, Vanessa, noted, “yeah, until we got the [Connected Students] devices, we had one laptop between the four of us that are here. And Noel had the majority use of that because that was his school work took priority”. This lack of individuated access to a device would make participation in some research designs difficult, particularly those that rely on regular access to a suitable device. Skills Despite the Connected Students program’s provision of data and device access, this did not ensure successful research participation. Many households struggled to engage with video research interviews due to insufficient digital skills. While a household with Internet connectivity might be considered on the “right” side of the digital divide, connectivity alone does not ensure participation. People also need to have the knowledge and skills required to use online resources. Brianna’s household, for example, had downloaded Microsoft Teams to their desktop computer in readiness for the interview, but had neglected to consider whether that device had video or audio capabilities. To work around this restriction, the household decided to complete the interview via the Connected Students laptop, but this too proved difficult. Neither Brianna nor her parents were confident in transferring the link to the interview between devices, whether by email or otherwise, requiring the researchers to talk them through the steps required to log on, find, and send the link via email. While Brianna’s household faced digital skills challenges that affected both parent and student participants, in others such as Ariel’s, these challenges were focussed at the parental level. In these instances, the student participant provided a vital resource, helping adults navigate platforms and participate in the research. As Celeste, Ariel’s parent, explained, it's just new things that I get a bit – like, even on here, because your email had come through to me and I said to Ariel "We're going to use your computer with Teams. How do we do this?" So, yeah, worked it out. I just had to look up my email address, but I [initially thought] oh, my god; what am I supposed to do here? Although helpful in our own research given its focus on school-aged young people, this dynamic of parents being helped by their dependents illustrates that the adults in our sample were often unfamiliar with the digital skills required for video conferencing. Research focussing only on adults, or on households in which students have not developed these skills through extended periods of online education such as occurred during the COVID-19 lockdowns, may find participants lacking the digital skills to participate in video interviews. Participation was also impacted upon by participants' lack of more subtle digital skills around the norms and conventions of video conferencing. Several households, for example, conducted their interviews in less ideal situations, such as from both moving and parked cars. A portion of the household interview with Piper’s household was completed as they drove the 30 minutes from their home into Shepperton. Due to living out of town, this household often experienced poor reception. The interview was thus regularly disrupted as they dropped in and out of range, with the interview transcript peppered with interjections such as “we’re going through a bit of an Internet light spot ... we’re back ... sorry ...” (Karina, parent). Finally, Piper switched the device on which they were taking the interview to gain a better connection: “my iPad that we were meeting on has worse Internet than my phone Internet, so we kind of changed it around” (Karina). Choosing to participate in the research from locations other than the home provides evidence of the limited time available to these families, and the onerousness of research participation. These choices also indicate unfamiliarity with video conferencing norms. As digitally excluded households, these participants were likely not the target of popular discussions throughout the pandemic about optimising video conferences through careful consideration of lighting, background, make-up and positioning (e.g. Lasky; Niven-Phillips). This was often identified by how participants positioned themselves in front of the camera, often choosing not to sit squarely within the camera lens. Sometimes this was because several household members were participating and struggled to all sit within view of the single device, but awkward camera positioning also occurred with only one or two people present. A number of interviews were initially conducted with shoulders, or foreheads, or ceilings rather than “whole” participants until we asked them to reposition the device so that the camera was pointing towards their faces. In noting this unfamiliarity we do not seek to criticise or apportion responsibility for accruing such skills to participating households, but rather to highlight the impact this had on the type of conversation between researcher and participant. Such practices offer valuable insight into how digital exclusion impacts on individual’s everyday lives as well as on their research participation. Conclusion Throughout the pandemic, digital methods such as video conferencing have been invaluable for researchers. However, while these methods have enabled fieldwork to continue despite COVID-19 disruptions, the shift to online platforms has important and under-acknowledged implications for who is and is not able to participate in research. In this article, we have drawn on our research with low-income households to demonstrate the barriers that such cohorts experience when participating in online research. Without the technology kits provided as part of our research design, these households would have struggled to participate due to a lack of adequate data and devices. Further, even with the kits provided, households faced additional barriers due to a lack of digital literacy. These experiences raise a number of questions that we encourage researchers to consider when designing methods that avoid in person interactions, and when reviewing studies that use similar approaches: who doesn’t have the technological access needed to participate in digital and online research? What are the implications of this for who and what is most visible in research conducted during the pandemic? Beyond questions of access, to what extent will disadvantaged populations not volunteer to participate in online research because of discomfort or unfamiliarity with digital tools and norms? When low-income participants are included, how can researchers ensure that participation does not unduly burden them by using up precious data resources? And, how can researchers facilitate positive and meaningful participation among those who might be less comfortable interacting through mediums like video conferencing? In raising these questions we acknowledge that not all research will or should be focussed on engaging with disadvantaged cohorts. Rather, our point is that through asking questions such as this, we will be better able to reflect on how data and participant samples are being impacted upon by shifts to digital methods during COVID-19 and beyond. As researchers, we may not always be able to adapt Zoom-based methods to be fully inclusive, but we can acknowledge this as a limitation and keep it in mind when reporting our findings, and later when engaging with the research that was largely conducted online during the pandemic. Lastly, while the Connected Students project focusses on impacts of affordability on digital inclusion, digital disadvantage intersects with many other forms of disadvantage. Thus, while our study focussed specifically on financial disadvantage, our call to be aware of who is and is not able to participate in Zoom-based research applies to digital exclusion more broadly, whatever its cause.

Saturday, 24 July 1971, Tower Mill Hotel The man jiggles the brick, gauges its weight. His stout hand, a flash of his watch dial, the sleeve rolled back, muscles on the upper arm bundled tight. His face half-erased by the dark. There’s something going on beneath the surface that Murray can’t grasp. He thinks of the three witches in Polanski’s Macbeth, huddled together on the beach, digging a circle in the sand with bare hands, unwrapping their filthy bundle. A ritual. The brick’s in the air and it’s funny but Murray expected it to spin but it doesn’t, it holds its position, arcs forward, as though someone’s taken the sky and pulled it sideways to give the impression of movement, like those chase scenes in the Punch and Judy shows you don’t see anymore. The brick hits the cement and fractures. Red dust on cops’ shined shoes. Murray feels the same sense of shock he’d felt, sitting in the sagging canvas seat at one of his film nights, recognising the witches’ bundle, a severed human arm, hacked off just before the elbow; both times looking so intently, he had no distance or defence when the realisation came. ‘What is it?’ says Lan. Murray points to the man who threw the brick but she is looking the other way, at a cop in a white riot helmet, head like a globe, swollen up as though bitten. Lan stands on Murray’s feet to see. The pig yells through a megaphone: ‘You’re occupying too much of the road. It’s illegal. Step back. Step back.’ Lan’s back is pressed against Murray’s stomach; her bum fits snugly to his groin. He resists the urge to plant his cold hands on her warm stomach, to watch her squirm. She turns her head so her mouth is next to his ear, says, ‘Don’t move.’ She sounds winded, her voice without force. He’s pinned to the ground by her feet. Again, ‘Step back. Step back.’ Next to him, Roger begins a chant. ‘Springboks,’ he yells, the rest of the crowd picking up the chant, ‘out now!’ ‘Springboks!’ ‘Out now!’ Murray looks up, sees a hand pressed against the glass in one of the hotel’s windows, quickly withdrawn. The hand belongs to a white man, for sure. It must be one of the footballers, although the gesture is out of keeping with his image of them. Too timid. He feels tired all of a sudden. But Jacobus Johannes Fouché’s voice is in his head, these men—the Springboks—represent the South African way of life, and the thought of the bastard Bjelke inviting them here. He, Roger and Lan were there the day before when the footballers pulled up outside the Tower Mill Hotel in a black and white bus. ‘Can you believe the cheek of those bastards?’ said Roger when they saw them bounding off the bus, legs the span of Murray’s two hands. A group of five Nazis had been lined up in front of the glass doors reflecting the city, all in uniform: five sets of white shirts and thin black ties, five sets of khaki pants and storm-trooper boots, each with a red sash printed with a black and white swastika tied around their left arms, just above the elbow. The Springboks strode inside, ignoring the Nazi’s salute. The protestors were shouting. An apple splattered wetly on the sidewalk. Friday, 7 April 1972, St Lucia Lan left in broad daylight. Murray didn’t know why this upset him, except that he had a vague sense that she should’ve gone in the night time, under the cover of dark. The guilty should sneak away, with bowed heads and faces averted, not boldly, as though going for an afternoon walk. Lan had pulled down half his jumpers getting the suitcase from the top of the cupboard. She left his clothes scattered across the bedroom, victims of an explosion, an excess of emotion. In the two days after Lan left, Murray scours the house looking for some clue to where she was, maybe a note to him, blown off the table in the wind, or put down and forgotten in the rush. Perhaps there was a letter from her parents, bankrupt, demanding she return to Vietnam. Or a relative had died. A cousin in the Viet Cong napalmed. He finds a packet of her tampons in the bathroom cupboard, tries to flush them down the toilet, but they keep floating back up. They bloat; the knotted strings make them look like some strange water-dwelling creature, paddling in the bowl. He pees in the shower for a while, but in the end he scoops the tampons back out again with the holder for the toilet brush. The house doesn’t yield anything, so he takes to the garden, circles the place, investigates its underbelly. The previous tenant had laid squares of green carpet underneath, off-cuts that met in jagged lines, patches of dirt visible. Murray had set up two sofas, mouldy with age, on the carpeted part, would invite his friends to sit with him there, booze, discuss the state of the world and the problem with America. Roger rings in the afternoon, says, ‘What gives? We were supposed to have lunch.’ Murray says, ‘Lan’s left me.’ He knows he will cry soon. ‘Oh Christ. I’m so sorry,’ says Roger. Murray inhales, snuffs up snot. Roger coughs into the receiver. ‘It was just out of the blue,’ says Murray. ‘Where’s she gone?’ ‘I don’t know.’ ‘She didn’t say anything?’ ‘No,’ says Murray. ‘She could be anywhere. Maybe you should call the police, put in a missing report,’ says Roger. ‘I’m not too friendly with the cops,’ says Murray, and coughs. ‘You sound a bit crook. I’ll come over,’ says Roger. ‘That’d be good,’ says Murray. Roger turns up at the house an hour later, wearing wide pants and a tight collared shirt with thick white and red stripes. He’s growing a moustache, only cuts his hair when he visits his parents. Murray says, ‘I’ll make us a cuppa.’ Roger nods, sits down at the vinyl table with his hands resting on his knees. He says, ‘Are you coming to 291 on Sunday?’ 291 St Paul’s Terrace is the Brisbane Communist Party’s headquarters. Murray says, ‘What’s on?’ ‘Billy needs someone to look after the bookshop.’ Murray gives Roger a mug of tea, sits down with his own mug between his elbows, and cradles his head in his hands so his hair falls over his wrists. After a minute, Roger says, ‘Does her family know?’ Murray makes a strange noise through his hands. ‘I don’t even know how to contact them,’ he says. ‘She wrote them letters—couldn’t afford to phone—but she’s taken everything with her. The address book. Everything.’ Murray knows nothing of the specifics of Lan’s life before she met him. She was the first Asian he’d ever spoken to. She wore wrap-around skirts that changed colour in the sun; grew her hair below the waist; sat in the front row in class and never spoke. He liked the shape of her calf as it emerged from her skirt. He saw her on the great lawn filming her reflection in a window with a Sony Portapak and knew that he wanted her more than anything. Murray seduced her by saying almost nothing and touching her as often as he could. He was worried about offending her. What reading he had done made him aware of his own ignorance, and his friend in Psych told him that when you touch a girl enough — especially around the aureole — a hormone is released that bonds them to you, makes them sad when you leave them or they leave you. In conversation, Murray would put his hand on Lan’s elbow, once on the top of her head. Lan was ready to be seduced. Murray invited her to a winter party in his backyard. They kissed next to the fire and he didn’t notice until the next morning that the rubber on the bottom of his shoe melted in the flames. She moved into his house quickly, her clothes bundled in three plastic bags. He wanted her to stay in bed with him all day, imagined he was John Lennon and she Yoko Ono. Their mattress became a soup of discarded clothes, bread crumbs, wine stains, come stains, ash and flakes of pot. He resented her when she told him that she was bored, and left him, sheets pulled aside to reveal his erection, to go to class. Lan tutored high-schoolers for a while, but they complained to their mothers that they couldn’t understand her accent. She told him her parents wanted her to come home. The next night he tidied the house, and cooked her dinner. Over the green peas and potato—Lan grated ginger over hers, mixed it with chili and soy sauce, which she travelled all the way to Chinatown on a bus to buy—Murray proposed. They were married in the botanic gardens, surrounded by Murray’s friends. The night before his father called him up and said, ‘It’s not too late to get out of it. You won’t be betraying the cause.’ Murray said, ‘You have no idea what this means to me,’ and hung up on him. Sunday, 9 April 1972, 291 St Paul’s Terrace Murray perches on the backless stool behind the counter in The People’s Bookshop. He has the sense he is on the brink of something. His body is ready for movement. When a man walks into the shop, Murray panics because Billy hadn’t shown him how to use the cash register. He says, ‘Can I help?’ anyway. ‘No,’ says the man. The man walks the length of the shelves too fast to read the titles. He stops at a display of Australiana on a tiered shelf, slides his hand down the covers on display. He pauses at Crocodile Hunt. The cover shows a drawing of a bulky crocodile, scaled body bent in an S, its jaws under the man’s thumb. He picks it up, examines it. Murray thinks it odd that he doesn’t flip it over to read the blurb. He walks around the whole room once, scanning the shelves, reaches Murray at the counter and puts the book down between them. Murray picks it up, turns it over, looking for a price. It’s stuck on the back in faded ink. He opens his mouth to tell the man how much, and finds him staring intently at the ceiling. Murray looks up too. A hairline crack runs along the surface and there are bulges in the plaster where the wooden framework’s swollen. It’s lower than Murray remembers. He thinks that if he stood on his toes he could reach it with the tips of his fingers. Murray looks down again to find the man staring at him. Caught out, Murray mutters the price, says, ‘You don’t have it in exact change, do you?’ The man nods, fumbles around in his pocket for a bit and brings out a note, which he lays at an angle along the bench top. He counts the coins in the palm of his hand. He makes a fist around the coins, brings his hand over the note and lets go. The coins fall, clinking, over the bench. One spins wildly, rolls past Murray’s arm and across the bench. Murray lets it fall. He recognises the man now; it is the act of release that triggers the memory, the fingers spread wide, the wrist bent, the black watch band. This is the man who threw the brick in the Springbok protest. Dead set. He looks up again, expecting to see the same sense of recognition in the man, but he is walking out of the shop. Murray follows him outside, leaving the door open and the money still on the counter. The man is walking right along St Paul’s Terrace. He tucks the book under his arm to cross Barry Parade, as though he might need both hands free to wave off the oncoming traffic. Murray stands on the other side of the road, unsure of what to do. When Murray came outside, he’d planned to hail the man, tell him he recognised him from the strike and was a fellow comrade. They give discounts to Communist Party members. Outside the shop, it strikes him that perhaps the man is not one of them at all. Just because he was at the march doesn’t make him a communist. Despite the unpopularity of the cause —‘It’s just fucking football,’ one of Murray’s friends had said. ‘What’s it got to do with anything?’— there had been many types there, a mixture of labour party members; unionists; people in the Radical Club and the Eureka Youth League; those not particularly attached to anyone. He remembers again the brick shattered on the ground. It hadn’t hit anyone, but was an incitement to violence. This man is dangerous. Murray is filled again with nervous energy, which leaves him both dull-witted and super-charged, as though he is a wind-up toy twisted tight and then released, unable to do anything but move in the direction he’s facing. He crosses the road about five metres behind the man, sticks to the outer edge of the pavement, head down. If he moves his eyes upwards, while still keeping his neck lowered, he can see the shoes of the man, his white socks flashing with each step. The man turns the corner into Brunswick Street. He stops at a car parked in front of the old Masonic Temple. Murray walks past fast, unsure of what to do next. The Temple’s entry is set back in the building, four steps leading up to a red door. Murray ducks inside the alcove, looks up to see the man sitting in the driver’s seat pulling out the pages of Crocodile Hunt and feeding them through the half wound-down window where they land, fanned out, on the road. When he’s finished dismembering the book, the man spreads the page-less cover across the back of the car. The crocodile, snout on the side, one eye turned outwards, stares out into the street. The man flicks the ignition and drives, the pages flying out and onto the road in his wake. Murray sits down on the steps of the guild and smokes. He isn’t exactly sure what just happened. The man must have bought the book just because he liked the picture on the front of the cover. But it’s odd though that he had bothered to spend so much just for one picture. Murray remembers how he had paced the shop and studiously examined the ceiling. He’d given the impression of someone picking out furniture for the room, working out the dimensions so some chair or table would fit. A cough. Murray looks up. The man’s standing above him, his forearm resting on the wall, elbow bent. His other arm hangs at his side, hand bunched up around a bundle of keys. ‘I wouldn’t of bothered following me, if I was you,’ the man says. ‘The police are on my side. Special branch are on my side.’ He pushes himself off the wall, stands up straight, and says, ‘Heil Hitler.’ Tuesday April 19, 1972, 291 St Paul’s Terrace Murray brings his curled fist down on the door. It opens with the force of his knock and he feels like an idiot for even bothering. The hallway’s dark. Murray runs into a filing cabinet, swears, and stands in the centre of the corridor, with his hand still on the cabinet, calling, ‘Roger! Roger!’ Murray told Roger he’d come here when he called him. Murray was walking back from uni, and on the other side of the road to his house, ready to cross, he saw there was someone standing underneath the house, looking out into the street. Murray didn’t stop. He didn’t need to. He knew it was the man from the bookshop, the Nazi. Murray kept walking until he reached the end of the street, turned the corner and then ran. Back on campus, he shut himself in a phone box and dialed Roger’s number. ‘I can’t get to my house,’ Murray said when Roger picked up. ‘Lock yourself out, did you?’ said Roger. ‘You know that Nazi? He’s back again.’ ‘I don’t get it,’ said Roger. ‘It doesn’t matter. I need to stay with you,’ said Murray. ‘You can’t. I’m going to a party meeting.’ ‘I’ll meet you there.’ ‘Ok. If you want.’ Roger hung up. Now, Roger stands framed in the doorway of the meeting room. ‘Hey Murray, shut up. I can hear you. Get in here.’ Roger switches on the hallway light and Murray walks into the meeting room. There are about seven people, sitting on hard metal chairs around a long table. Murray sits next to Roger, nods to Patsy, who has nice breasts but is married. Vince says, ‘Hi, Murray, we’re talking about the moratorium on Friday.’ ‘You should bring your pretty little Vietnamese girl,’ says Billy. ‘She’s not around anymore,’ says Roger. ‘That’s a shame,’ says Patsy. ‘Yeah,’ says Murray. ‘Helen Dashwood told me her school has banned them from wearing moratorium badges,’ says Billy. ‘Far out,’ says Patsy. ‘We should get her to speak at the rally,’ says Stella, taking notes, and then, looking up, says, ‘Can anyone smell burning?’ Murray sniffs, says ‘I’ll go look.’ They all follow him down the hall. Patsy says, behind him, ‘Is it coming from the kitchen?’ Roger says, ‘No,’ and then the windows around them shatter. Next to Murray, a filing cabinet buckles and twists like wet cardboard in the rain. A door is blown off its hinges. Murray feels a moment of great confusion, a sense that things are sliding away from him spectacularly. He’s felt this once before. He wanted Lan to sit down with him, but she said she didn’t want to be touched. He’d pulled her to him, playfully, a joke, but he was too hard and she went limp in his hands. Like she’d been expecting it. Her head hit the table in front of him with a sharp, quick crack. He didn’t understand what happened; he had never experienced violence this close. He imagined her brain as a line drawing with the different sections coloured in, like his Psych friend had once showed him, except squashed in at the bottom. She had recovered, of course, opened her eyes a second later to him gasping. He remembered saying, ‘I just want to hold you. Why do you always do this to me?’ and even to him it hadn’t made sense because he was the one doing it to her. Afterwards, Murray had felt hungry, but couldn’t think of anything that he’d wanted to eat. He sliced an apple in half, traced the star of seeds with his finger, then decided he didn’t want it. He left it, already turning brown, on the kitchen bench. Author’s Note No one was killed in the April 19 explosion, nor did the roof fall in. The bookstore, kitchen and press on the first floor of 291 took the force of the blast (Evans and Ferrier). The same night, a man called The Courier Mail (1) saying he was a member of a right wing group and had just bombed the Brisbane Communist Party Headquarters. He threatened to bomb more on Friday if members attended the anti-Vietnam war moratorium that day. He ended his conversation with ‘Heil Hitler.’ Gary Mangan, a known Nazi party member, later confessed to the bombing. He was taken to court, but the Judge ruled that the body of evidence was inadmissible, citing a legal technicality. Mangan was not charged.Ian Curr, in his article, Radical Books in Brisbane, publishes an image of the Communist party quarters in Brisbane. The image, entitled ‘After the Bomb, April 19 1972,’ shows detectives interviewing those who were in the building at the time. One man, with his back to the camera, is unidentified. I imagined this unknown man, in thongs with the long hair, to be Murray. It is in these gaps in historical knowledge that the writer of fiction is free to imagine.

If Continental social theory emerges from a climate of intensely cold winters and short mild summers, how does Australia (or any nation defined by its large masses of aridity) function as an environment in which to produce critical theory and new knowledge? Climate and weather are intrinsic to ambience, but what impact might they have on the conditions of producing academic work? How is ambience relevant to thinking and writing and research? Is there an ambient epistemology? This paper argues that the ambient is an unacknowledged factor in the production of critical thinking, and draws on examples of academics locating their writing conditions as part of their thinking. This means paying attention to the embodied work of thinking, and so I locate myself in order to explore what it might mean to acknowledge the conditions of intellectual work. Consequently I dwell on the impact of heat and light as qualities specific to where I work, but (following Bolt) I also argue that they are terms that are historically associated with new knowledge. Language, then, is already a factor in shaping the way we can think through such conditions, and the narratives available to write about them. Working these conditions into critical narratives may involve mobilising fictional tropes, and may not always be ambient, but they are potent in the academic imaginary and impact the ways in which we can think through location. Present Tense As I sit in Perth right now in a balmy 27 degrees Celsius with the local afternoon sea-breeze (fondly known as the Fremantle Doctor) clearing the stuffiness and humidity of the day, environmental conditions are near perfect for the end of summer. I barely notice them. Not long ago though, it was over 40 degrees for three days in a row. These were the three days I had set aside to complete an academic paper, the last days available before the university opened and normal work would resume. I’d arranged to have the place to myself, but I hadn’t arranged for cooling technologies. As I immersed myself in photocopies and textbooks the intellectual challenges and excitement were my preoccupation. It was hot, but I was almost unreceptive to recognising the discomforts of the weather until sweat began to drip onto pages and keyboards. A break in the afternoon for a swim at the local beach was an opportunity to clarify and see the bigger picture, and as the temperature began to slide into the evening cool it was easier to stay up late working and then sleep in late. I began to work around the weather. What impact does this have on thinking and writing? I remember it as a haze. The paper though, still seems clear and reasoned. My regimen might be read as working despite the weather, but I wonder if the intensity of the heat extends thinking in different directions—to go places where I wouldn’t have imagined in an ambiently cooled office (if I had one). The conditions of the production of knowledge are often assumed to be static, stable and uninteresting. Even if your work is located in exciting Other places, the ‘writing up’ is expected to happen ‘back home’, after the extra-ordinary places of fieldwork. It can be written in the present tense, for a more immediate reading experience, but the writing cannot always happen at the same time as the events being described, so readers accept the use of present tense as a figment of grammar that cannot accommodate the act of writing. When a writer becomes aware of their surroundings and articulates those conditions into their narrative, the reader is lifted out of the narrative into a metaframe; out of the body of writing and into the extra-diegetic. In her essay “Me and My Shadow” (1987), Jane Tompkins writes as if ‘we’ the reader are in the present with her as she makes connections between books, experiences, memories, feelings, and she also provides us with a writing scene in which to imagine her in the continuous present: It is a beautiful day here in North Carolina. The first day that is both cool and sunny all summer. After a terrible summer, first drought, then heat-wave, then torrential rain, trees down, flooding. Now, finally, beautiful weather. A tree outside my window just brushed by red, with one fully red leaf. (This is what I want you to see. A person sitting in stockinged feet looking out of her window – a floor to ceiling rectangle filled with green, with one red leaf. The season poised, sunny and chill, ready to rush down the incline into autumn. But perfect, and still. Not going yet.) (128)This is a strategy, part of the aesthetics and politics of Tompkins’s paper which argues for the way the personal functions in intellectual thinking and writing even when we don’t recognise or acknowledge it. A little earlier she characterises herself as vulnerable because of the personal/professional nexus: I don’t know how to enter the debate [over epistemology] without leaving everything else behind – the birds outside my window, my grief over Janice, just myself as a person sitting here in stockinged feet, a little bit chilly because the windows are open, and thinking about going to the bathroom. But not going yet. (126)The deferral of autumn and going to the bathroom is linked through the final phrase, “not going yet”. This is a kind of refrain that draws attention to the aesthetic architecture of locating the self, and yet the reference to an impending toilet trip raised many eyebrows. Nancy Millar comments that “these passages invoke that moment in writing when everything comes together in a fraction of poise; that fragile moment the writing in turn attempts to capture; and that going to the bathroom precisely, will end” (6). It spoils the moment. The aesthetic green scene with one red leaf is ruptured by the impending toilet scene. Or perhaps it is the intimacy of bodily function that disrupts the ambient. And yet the moment is fictional anyway. There must surely always be some fiction involved when writing about the scene of writing, as writing usually takes more than one take. Gina Mercer takes advantage of this fictional function in a review of a collection of women’s poetry. Noting the striking discursive differences between the editor’s introduction and the poetry collected in the volume, she suggestively accounts for this by imagining the conditions under which the editor might have been working: I suddenly begin to imagine that she wrote the introduction sitting at her desk in twin-set and pearls, her feet constricted by court shoes – but that the selection took place at home with her lying on a large beautifully-linened bed bestrewn by a cat and the poems… (4)These imaginary conditions, Mercer implies, impact on the ways we do our intellectual work, or perhaps different kinds of work require different conditions. Mercer not only imagines the editor at work, but also suggests her own preferred workspace when she mentions that “the other issue I’ve been pondering as I lay on my bed in a sarong (yes it’s hot here already) reading this anthology, has been the question of who reads love poetry these days?” (4). Placing herself as reader (of an anthology of love poetry) on the bed in a sarong in a hot climate partially accounts for the production of the thinking around this review, but probably doesn’t include the writing process. Mercer’s review is written in epistolary form, signaling an engagement with ‘the personal’, and yet that awareness of form and setting performs a doubling function in which scenes are set and imagination is engaged and yet their veracity doesn’t seem important, and may even be part of the fiction of form. It’s the idea of working leisurely that gains traction in this review. Despite the capacity for fiction, I want to believe that Jane Tompkins was writing in her study in North Carolina next to a full-length window looking out onto a tree. I’m willing to suspend my disbelief and imagine her writing in this place and time. Scenes of Writing Physical conditions are often part of mythologising a writer. Sylvia Plath wrote the extraordinary collection of poems that became Ariel during the 1962/63 London winter, reputed to have been the coldest for over a hundred years (Gifford 15). The cold weather is given a significant narrative role in the intensity of her writing and her emotional desperation during that period. Sigmund Freud’s writing desk was populated with figurines from his collection of antiquities looking down on his writing, a scene carefully replicated in the Freud Museum in London and reproduced in postcards as a potent staging of association between mythology, writing and psychoanalysis (see Burke 2006). Writer’s retreats at the former residences of writers (like Varuna at the former home of Eleanor Dark in the Blue Mountains, and the Katherine Susannah Pritchard Centre in the hills outside of Perth) memorialise the material conditions in which writers wrote. So too do pilgrimages to the homes of famous writers and the tourism they produce in which we may gaze in wonder at the ordinary places of such extraordinary writing. The ambience of location is one facet of the conditions of writing. When I was a doctoral student reading Continental feminist philosophy, I used anything at hand to transport myself into their world. I wrote my dissertation mostly in Townsville in tropical Queensland (and partly in Cairns, even more tropical), where winter is blue skies and mid-twenties in temperature but summers are subject to frequent build-ups in pressure systems, high humidity, no breeze and some cyclones. There was no doubt that studying habits were affected by the weather for a student, if not for all the academics who live there. Workplaces were icily air-conditioned (is this ambient?) but outside was redolent with steamy tropical evenings, hot humid days, torrential downpours. When the weather breaks there is release in blood pressure accompanying barometer pressure. I was reading contemporary Australian literature alongside French feminist theories of subjectivity and their relation through écriture féminine. The European philosophical and psychoanalytic tradition and its exquisitely radical anti-logical writing of Irigaray, Cixous and Kristeva seemed alien to my tropical environs but perversely seductive. In order to get ‘inside’ the theoretical arguments, my strategy was to interpolate myself into their imagined world of writing, to emulate their imagined conditions. Whenever my friend went on a trip, I caretook her 1940s unit that sat on a bluff and looked out over the Coral Sea, all whitewashed and thick stone, and transformed it into a French salon for my intellectual productivity. I played Edith Piaf and Grace Jones, went to the grocer at the bottom of the hill every day for fresh food and the French patisserie for baguettes and croissants. I’d have coffee brewing frequently, and ate copious amounts of camembert and chocolate. The Townsville flat was a Parisian salon with French philosophers conversing in my head and between the piles of book lying on the table. These binges of writing were extraordinarily productive. It may have been because of the imagined Francophile habitus (as Bourdieu understands it); or it may have been because I prepared for the anticipated period of time writing in a privileged space. There was something about adopting the fictional romance of Parisian culture though that appealed to the juxtaposition of doing French theory in Townsville. It intensified the difference but interpolated me into an intellectual imaginary. Derrida’s essay, “Freud and the Scene of Writing”, promises to shed light on Freud’s conditions of writing, and yet it is concerned moreover with the metaphoric or rather intellectual ‘scene’ of Freudian ideas that form the groundwork of Derrida’s own corpus. Scenic, or staged, like Tompkins’s framed window of leaves, it looks upon the past as a ‘moment’ of intellectual ferment in language. Peggy Kamuf suggests that the translation of this piece of Derrida’s writing works to cover over the corporeal banishment from the scene of writing, in a move that privileges the written trace. In commenting, Kamuf translates Derrida herself: ‘to put outside and below [metre dehors et en bas] the body of the written trace [le corps de la trace écrite].’ Notice also the latter phrase, which says not the trace of the body but the body of the trace. The trace, what Derrida but before him also Freud has called trace or Spur, is or has a body. (23)This body, however, is excised, removed from the philosophical and psychoanalytic imaginary Kamuf argues. Australian philosopher Elizabeth Grosz contends that the body is “understood in terms that attempt to minimize or ignore altogether its formative role in the production of philosophical values – truth, knowledge, justice” (Volatile 4): Philosophy has always considered itself a discipline concerned primarily or exclusively with ideas, concepts, reason, judgment – that is, with terms clearly framed by the concept of mind, terms which marginalize or exclude considerations of the body. As soon as knowledge is seen as purely conceptual, its relation to bodies, the corporeality of both knowers and texts, and the ways these materialities interact, must become obscure. (Volatile 4)In the production of knowledge then, the corporeal knowing writing body can be expected to interact with place, with the ambience or otherwise in which we work. “Writing is a physical effort,” notes Cixous, and “this is not said often enough” (40). The Tense Present Conditions have changed here in Perth since the last draft. A late summer high pressure system is sitting in the Great Australian Bite pushing hot air across the desert and an equally insistent ridge of low pressure sits off the Indian Ocean, so the two systems are working against each other, keeping the weather hot, still, tense, taut against the competing forces. It has been nudging forty degrees for a week. The air conditioning at work has overloaded and has been set to priority cooling; offices are the lowest priority. A fan blasts its way across to me, thrumming as it waves its head from one side to the other as if tut-tutting. I’m not consumed with intellectual curiosity the way I was in the previous heatwave; I’m feeling tired, and wondering if I should just give up on this paper. It will wait for another time and journal. There’s a tension with chronology here, with what’s happening in the present, but then Rachel Blau DuPlessis argues that the act of placing ideas into language inevitably produces that tension: Chronology is time depicted as travelling (more or less) in a (more or less) forward direction. Yet one can hardly write a single sentence straight; it all rebounds. Even its most innocent first words – A, The, I, She, It – teem with heteroglossias. (16)“Sentences structure” DuPlessis points out, and grammar necessitates development, chronological linearity, which affects the possibilities for narrative. “Cause and effect affect” DuPlessis notes (16), as do Cixous and Irigaray before her. Nevertheless we must press on. And so I leave work and go for a swim, bring my core body temperature down, and order a pot of tea from the beach café while I read Barbara Bolt in the bright afternoon light. Bolt is a landscape painter who has spent some time in Kalgoorlie, a mining town 800km east of Perth, and notes the ways light is used as a metaphor for visual illumination, for enlightening, and yet in Kalgoorlie light is a glare which, far from illuminating, blinds. In Kalgoorlie the light is dangerous to the body, causing cancers and cataracts but also making it difficult to see because of its sheer intensity. Bolt makes an argument for the Australian light rupturing European thinking about light: Visual practice may be inconceivable without a consideration of light, but, I will argue, it is equally ‘inconceivable’ to practice under European notions of light in the ‘glare’ of the Australian sun. Too much light on matter sheds no light on the matter. (204)Bolt frequently equates the European notions of visual art practice that, she claims, Australians still operate under, with concomitant concepts of European philosophy, aesthetics and, I want to add, epistemology. She is particularly adept at noting the material impact of Australian conditions on the body, arguing that, the ‘glare’ takes apart the Enlightenment triangulation of light, knowledge, and form. In fact, light becomes implicated bodily, in the facts of the matter. My pterygiums and sun-beaten skin, my mother and father’s melanomas, and the incidence of glaucoma implicate the sun in a very different set of processes. From my optic, light can no longer be postulated as the catalyst that joins objects while itself remaining unbent and unimplicated … (206).If new understandings of light are generated in Australian conditions of working, surely heat is capable of refiguring dominant European notions as well. Heat is commonly associated with emotions and erotics, even through ideas: heated debate, hot topics and burning issues imply the very latest and most provocative discussions, sizzling and mercurial. Heat has a material affect on corporeality also: dehydrating, disorienting, dizzying and burning. Fuzzy logic and bent horizons may emerge. Studies show that students learn best in ambient temperatures (Pilman; Graetz), but I want to argue that thought and writing can bend in other dimensions with heat. Tensions build in blood pressure alongside isometric bars. Emotional and intellectual intensities merge. Embodiment meets epistemology. This is not a new idea; feminist philosophers like Donna Haraway have been emphasizing the importance of situated knowledge and partial perspective for decades as a methodology that challenges universalism and creates a more ethical form of objectivity. In 1987 Haraway was arguing for politics and epistemologies of location, positioning, and situating, where partiality and not universality is the condition of being heard to make rational knowledge claims. These are claims on people’s lives. I am arguing for the view from a body, always a complex contradictory structuring and structured body versus the view from above, from nowhere, from simplicity. (Haraway 588)Working in intellectual conditions when the specificities of ambience is ignored, is also, I suggest, to work in a privileged space, in which there are no distractions like the weather. It is also to work ‘from nowhere, from simplicity’ in Haraway’s words. It is to write from within the pure imaginary space of the intellect. But to write in, and from, weather conditions no matter what they might be is to acknowledge the affect of being-in-the-world, to recognise an ontological debt that is embodied and through which we think. I want to make a claim for the radical conditions under which writing can occur outside of the ambient, as I sit here sweating over theory again. Drawing attention to the corporeal conditions of the scene of writing is a way of situating knowledge and partial perspective: if I were in Hobart where snow still lies on Mount Wellington I may well have a different perspective, but the metaphors of ice and cold also need transforming into productive and generative conditions of particularised knowledge. To acknowledge the location of knowledge production suggests more of the forces at work in particular thinking, as a bibliography indicates the shelf of books that have inflected the written product. This becomes a relation of immanence rather than transcendence between the subject and thought, whereby thinking can be understood as an act, an activity, or even activism of an agent. This is proposed by Elizabeth Grosz in her later work where she yokes together the “jagged edges” (Time 165) of Deleuze and Irigaray’s work in order to reconsider the “future of thought”. She calls for a revision of meaning, as Bolt does, but this time in regard to thought itself—and the task of philosophy—asking whether it is possible to develop an understanding of thought that refuses to see thought as passivity, reflection, contemplation, or representation, and instead stresses its activity, how and what it performs […] can we deromanticize the construction of knowledges and discourses to see them as labor, production, doing? (Time 158)If writing is to be understood as a form of activism it seems fitting to conclude here with one final image: of Gloria Anzaldua’s computer, at which she invites us to imagine her writing her book Borderlands/La Frontera: The New Mestiza (1987), a radical Chicana vision for postcolonial theory. Like Grosz, Anzaldua is intent on undoing the mind/body split and the language through which the labour of thinking can be articulated. This is where she writes her manifesto: I sit here before my computer, Amiguita, my altar on top of the monitor with the Virgen de Coatalopeuh candle and copal incense burning. My companion, a wooden serpent staff with feathers, is to my right while I ponder the ways metaphor and symbol concretize the spirit and etherealize the body. (75) References Anzaldua, Gloria.

The debate on the social role of museums trundles along in an age where complex associations between community, collections, and cultural norms are highly contested (Silverman 3–4; Sandell, Inequality 3–23). This article questions whether, in the case of community groups whose aspirations often go unrecognised (in this case people with either blindness or low vision), there is a need to discuss and debate institutionalised approaches that often reinforce social exclusion and impede cultural access. If “access is [indeed] an entry point to experience” (Papalia), then the privileging of visual encounters in museums is clearly a barrier for people who experience sight loss or low vision (Levent and Pursley). In contrast, a multisensory aesthetic to exhibition display respects the gamut of human sensory experience (Dudley 161–63; Drobnick 268–69; Feld 184; James 136; McGlone 41–60) as do discursive gateways including “lectures, symposia, workshops, educational programs, audio guides, and websites” (Cachia). Independent access to information extends beyond Braille on toilet doors.Underpinning this article is an ongoing qualitative case study undertaken by the author involving participant observation, workshops, and interviews with eight adults who experience vision impairment. The primary research site has been the National Museum of Australia. Reflecting on the role of curators as storytellers and the historical development of museums and their practitioners as agents for social development, the article explores the opportunities latent in museum collections as they relate to community members with vision impairment. The outcomes of this investigation offer insights into emerging issues as they relate to the International Council of Museums (ICOM) definitions of the museum program. Curators as Storytellers“The ways in which objects are selected, put together, and written or spoken about have political effects” (Eilean Hooper-Greenhill qtd. in Sandell, Inequality 8). Curators can therefore open or close doors to discrete communities of people. The traditional role of curators has been to collect, care for, research, and interpret collections (Desvallées and Mairesse 68): they are characterised as information specialists with a penchant for research (Belcher 78). While commonly possessing an intimate knowledge of their institution’s collection, their mode of knowledge production results from a culturally mediated process which ensures that resulting products, such as cultural significance assessments and provenance determinations (Russell and Winkworth), privilege the knowing systems of dominant social groups (Fleming 213). Such ways of seeing can obstruct the access prospects of underserved audiences.When it comes to exhibition display—arguably the most public of work by museums—curators conventionally collaborate within a constellation of other practitioners (Belcher 78–79). Curators liaise with museum directors, converse with conservators, negotiate with exhibition designers, consult with graphics designers, confer with marketing boffins, seek advice from security, chat with editors, and engage with external contractors. I question the extent that curators engage with community groups who may harbour aspirations to participate in the exhibition experience—a sticking point soon to be addressed. Despite the team based ethos of exhibition design, it is nonetheless the content knowledge of curators on public display. The art of curatorial interpretation sets out not to instruct audiences but, in part, to provoke a response with narratives designed to reveal meanings and relationships (Freeman Tilden qtd. in Alexander and Alexander 258). Recognised within the institution as experts (Sandell, Inclusion 53), curators have agency—they decide upon the stories told. In a recent television campaign by the National Museum of Australia, a voiceover announces: a storyteller holds incredible power to connect and to heal, because stories bring us together (emphasis added). (National Museum of Australia 2015)Storytelling in the space of the museum often shares the histories, perspectives, and experiences of people past as well as living cultures—and these stories are situated in space and time. If that physical space is not fit-for-purpose—that is, it does not accommodate an individual’s physical, intellectual, psychiatric, sensory, or neurological needs (Disability Discrimination Act 1992, Cwlth)—then the story reaches only long-established patrons. The museum’s opportunity to contribute to social development, and thus the curator’s as the primary storyteller, will have been missed. A Latin-American PerspectiveICOM’s commitment to social development could be interpreted merely as a pledge to make use of collections to benefit the public through scholarship, learning, and pleasure (ICOM 15). If this interpretation is accepted, however, then any museum’s contribution to social development is somewhat paltry. To accept such a limited and limiting role for museums is to overlook the historical efforts by advocates to change the very nature of museums. The ascendancy of the social potential of museums first blossomed during the late 1960s at a time where, globally, overlapping social movements espoused civil rights and the recognition of minority groups (Silverman 12; de Varine 3). Simultaneously but independently, neighbourhood museums arose in the United States, ecomuseums in France and Quebec, and the integral museum in Latin America, notably in Mexico (Hauenschild; Silverman 12–13). The Latin-American commitment to the ideals of the integral museum developed out of the 1972 round table of Santiago, Chile, sponsored by the United Nations Educational, Scientific and Cultural Organization (Giménez-Cassina 25–26). The Latin-American signatories urged the local and regional museums of their respective countries to collaborate with their communities to resolve issues of social inequality (Round Table Santiago 13–21). The influence of Brazilian educator Paulo Freire should be acknowledged. In 1970, Freire ushered in the concept of conscientization, defined by Catherine Campbell and Sandra Jovchelovitch as:the process whereby critical thinking develops … [and results in a] … thinker [who] feels empowered to think and to act on the conditions that shape her living. (259–260)This model for empowerment lent inspiration to the ideals of the Santiago signatories in realising their sociopolitical goal of the integral museum (Assunção dos Santos 20). Reframing the museum as an institution in the service of society, the champions of the integral museum sought to redefine the thinking and practices of museums and their practitioners (United Nations Educational, Scientific and Cultural Organization 37–39). The signatories successfully lobbied ICOM to introduce an explicitly social purpose to the work of museums (Assunção dos Santos 6). In 1974, in the wake of the Santiago round table, ICOM modified their definition of a museum to “a permanent non-profit institution, open to the public, in the service of society and its development” (emphasis added) (Hauenschild). Museums had been transformed into “problem solvers” (Judite Primo qtd. in Giménez-Cassina 26). With that spirit in mind, museum practitioners, including curators, can develop opportunities for reciprocity with the many faces of the public (Guarini). Response to Social Development InitiativesStarting in the 1970s, the “second museum revolution” (van Mensch 6–7) saw the transition away from: traditional roles of museums [of] collecting, conservation, curatorship, research and communication … [and toward the] … potential role of museums in society, in education and cultural action. (van Mensch 6–7)Arguably, this potential remains a work in progress some 50 years later. Writing in the tradition of museums as agents of social development, Mariana Lamas states:when we talk about “in the service of society and its development”, it’s quite different. It is like the drunk uncle at the Christmas party that the family pretends is not there, because if they pretend long enough, he might pass out on the couch. (Lamas 47–48)That is not to say that museums have neglected to initiate services and programs that acknowledge the aspirations of people with disabilities (refer to Cachia and Krantz as examples). Without discounting such efforts, but with the refreshing analogy of the drunken uncle still fresh in memory, Lamas answers her own rhetorical question:how can traditional museums promote community development? At first the word “development” may seem too much for the museum to do, but there are several ways a museum can promote community development. (Lamas 52) Legitimising CommunitiesThe first way that museums can foster community or social development is to:help the community to over come [sic] a problem, coming up with different solutions, putting things into a new perspective; providing confidence to the community and legitimizing it. (Lamas 52)As a response, my doctoral investigation legitimises the right of people with vision impairment to participate in the social and cultural aspects of publicly funded museums. The Australian Government upheld this right in 2008 by ratifying the United Nations Convention on the Rights of Persons with Disabilities (and Optional Protocol), which enshrines the right of people with disability to participate in the cultural life of the nation (United Nations).At least 840,700 people in Australia (a minimum of four per cent of the population) experiences either blindness or low vision (Australian Bureau of Statistics 2009). For every one person in the Australian community who is blind, nearly five other people experience low vision. The medical model of disability identifies the impairment as the key feature of a person and seeks out a corrective intervention. In contrast, the social model of disability strives to remove the attitudinal, social, and physical barriers enacted by people or institutions (Landman, Fishburn, and Tonkin 14). Therein lies the opportunity and challenge for museums—modifying layouts and practices that privilege the visual. Consequently, there is scope for museums to partner with people with vision impairment to identify their aspirations rather than respond as a problem to be fixed. Common fixes in the museums for people with disabilities include physical alterations such as ramps and, less often, special tours (Cachia). I posit that curators, as co-creators and major contributors to exhibitions, can be part of a far wider discussion. In the course of doctoral research, I accompanied adults with a wide array of sight impairments into exhibitions at the Museum of Australian Democracy at Old Parliament House, the Australian War Memorial, and the National Museum of Australia. Within the space of the exhibition, the most commonly identified barrier has been the omission of access opportunities to interpreted materials: that is, information about objects on display as well as the wider narratives driving exhibitions. Often, the participant has had to work backwards, from the object itself, to understand the wider topic of the exhibition. If aesthetics is “the way we communicate through the senses” (Thrift 291), then the vast majority of exhibits have been inaccessible from a sensory perspective. For people with low vision (that is, they retain some degree of functioning sight), objects’ labels have often been too small to be read or, at times, poorly contrasted or positioned. Objects have often been set too deep into display cabinets or too far behind safety barriers. If individuals must use personal magnifiers to read text or look in vain at objects, then that is an indicator that there are issues with exhibition design. For people who experience blindness (that is, they cannot see), neither the vast majority of exhibits nor their interpretations have been made accessible. There has been minimal access across all museums to accessioned objects, handling collections, or replicas to tease out exhibits and their stories. Object labels must be read by family or friends—a tiring experience. Without motivated peers, the stories told by curators are silenced by a dearth of alternative options.Rather than presume to know what works for people with disabilities, my research ethos respects the “nothing about us without us” (Charlton 2000; Werner 1997) maxim of disability advocates. To paraphrase Lamas, we have collaborated to come up with different solutions by putting things into new perspectives. In turn, “person-centred” practices based on rapport, warmth, and respect (Arigho 206–07) provide confidence to a diverse community of people by legitimising their right to participate in the museum space. Incentivising Communities Museums can also nurture social or community development by providing incentives to “the community to take action to improve its quality of life” (Lamas 52). It typically falls to (enthusiastic) public education and community outreach teams to engage underserved communities through targeted programs. This approach continues the trend of curators as advocates for the collection, and educators as advocates for the public (Kaitavouri xi). If the exhibition briefs normally written by curators (Belcher 83) reinforced the importance of access, then exhibition designers would be compelled to offer fit-for-purpose solutions. Better still, if curators (and other exhibition team members) regularly met with community based organisations (perhaps in the form of a disability reference group), then museums would be better positioned to accommodate a wider spectrum of community members. The National Standards for Australian Museums and Galleries already encourages museums to collaborate with disability organisations (40). Such initiatives offer a way forward for improving a community’s sense of itself and its quality of life. The World Health Organization defines health as a “state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”. While I am not using quality of life indicators for my doctoral study, the value of facilitating social and cultural opportunities for my target audience is evident in participant statements. At the conclusion of one sensory based workshop, Mara, a female participant who experiences low vision in one eye and blindness in the other, stated:I think it was interesting in that we could talk together about what we were experiencing and that really is the social aspect of it. I mean if I was left to go to a whole lot of museums on my own, I probably wouldn’t. You know, I like going with kids or a friend visiting from interstate—that sort of thing. And so this group, in a way, replicates that experience in that you’ve got someone else to talk about your impressions with—much better than going on your own or doing this alone.Mara’s statement was in response to one of two workshops I held with the support of the Learning Services team at the National Museum of Australia in May 2015. Selected objects from the museum’s accessioned collection and handling collection were explored, as well as replicas in the form of 3D printed objects. For example, participants gazed upon and handled a tuckerbox, smelt and tasted macadamia nuts in wattle seed syrup, and listened to a genesis story about the more-ish nut recorded by the Butchulla people—the traditional owners of Fraser Island. We sat around a table while I, as the workshop mediator, sought to facilitate free-flowing discussions about their experiences and, in turn, mused on the capacity of objects to spark social connection and opportunities for cultural access. While the workshop provided the opportunity for reciprocal exchanges amongst participants as well as between participants and me, what was highly valued by most participants was the direct contact with members of the museum’s Learning Services team. I observed that participants welcomed the opportunity to talk with real museum workers. Their experience of museum practitioners, to date, had been largely confined to the welcome desk of respective institutions or through special events or tours where they were talked at. The opportunity to communicate directly with the museum allowed some participants to share their thoughts and feelings about the services that museums provide. I suggest that curators open themselves up to such exchanges on a more frequent basis—it may result in reciprocal benefits for all stakeholders. Fortifying IdentityA third way museums can contribute to social or community development is by:fortify[ing] the bonds between the members of the community and reaffirm their identities making them feel more secure about who they are; and give them a chance to tell their own version of their history to “outsiders” which empowers them. (Lamas 52)Identity informs us and others of who we are and where we belong in the world (Silverman 54). However, the process of identity marking and making can be fraught: “some communities are ours by choice … [and] … some are ours because of the ways that others see us” (Watson 4). Communities are formed by identifying who is in and who is out (Francois Dubet qtd. in Bessant and Watts 260). In other words, the construction of collective identity is reinforced through means of social inclusion and social exclusion. The participants of my study, as members or clients of the Royal Society for the Blind | Canberra Blind Society, clearly value participating in events with empathetic peers. People with vision impairment are not a homogenous group, however. Reinforcing the cultural influences on the formation of identity, Fiona Candlin asserts that “to state the obvious but often ignored fact, blind people … [come] … from all social classes, all cultural, racial, religious and educational backgrounds” (101). Irrespective of whether blindness or low vision arises congenitally, adventitiously, or through unexpected illness, injury, or trauma, the end result is an assortment of individuals with differing perceptual characteristics who construct meaning in often divergent ways (De Coster and Loots 326–34). They also hold differing world views. Therefore, “participation [at the museum] is not an end in itself. It is a means for creating a better world” (Assunção dos Santos 9). According to the Australian Human Rights Commissioner, Professor Gillian Triggs, a better world is: a society for all, in which every individual has an active role to play. Such a society is based on fundamental values of equity, equality, social justice, and human rights and freedoms, as well as on the principles of tolerance and embracing diversity. (Triggs)Publicly funded museums can play a fundamental role in the cultural lives of societies. For example, the Powerhouse Museum (Museum of Applied Arts and Sciences) in Sydney partnered with Vision Australia to host an exhibition in 2010 titled Living in a Sensory World: it offered “visitors an understanding of the world of the blindness and low vision community and celebrates their achievements” (Powerhouse Museum). With similar intent, my doctoral research seeks to validate the world of my participants by inviting museums to appreciate their aspirations as a distinct but diverse community of people. ConclusionIn conclusion, the challenge for museum curators and other museum practitioners is balancing what Richard Sennett (qtd. in Bessant and Watts 265) identifies as opportunities for enhancing social cohesion and a sense of belonging while mitigating parochialism and community divisiveness. Therefore, curators, as the primary focus of this article, are indeed challenged when asked to contribute to serving the public through social development—a public which is anything but homogenous. Mindful of cultural and social differences in an ever-changing world, museums are called to respect the cultural and natural heritage of the communities they serve and collaborate with (ICOM 10). It is a position I wholeheartedly support. This is not to say that museums or indeed curators are capable of solving the ills of society. However, inviting people who are frequently excluded from social and cultural events to multisensory encounters with museum collections acknowledges their cultural rights. I suggest that this would be a seismic shift from the current experiences of adults with blindness or low vision at most museums.ReferencesAlexander, Edward, and Mary Alexander.
