AbstractThis paper uses original documentary evidence held in the archives of the Wiltshire Archaeological and Natural History Society in Devizes to reassess the work of William Cunnington, FSA, carried out on behalf of Sir Richard Colt Hoare, and the contribution of his two principal excavators, Stephen and John Parker, of Heytesbury, in Wiltshire. Previously the Parkers have been regarded as little more than regular labourers on Cunnington’s pioneering excavations; the evidence now suggests that they (and in particular John) were, in fact, key to the success of Cunnington’s work. By the time of Cunnington’s death in 1810, John Parker was identifying new sites on the Wiltshire Downs and, on occasion, taking sole responsibility for excavating and interpreting them. After 1810 Hoare sponsored few further excavations and, though John was employed on at least one occasion, in 1814, the Parkers dropped back into obscurity and poverty without the regular employment, and perhaps protection, provided by Cunnington. Although John’s obituary in 1867 described him as Cunnington’s ‘principal pioneer’, no research has previously been undertaken that specifically considers the contribution of the Parkers in those early British excavations. This paper seeks to redress that oversight.

This paper brings together the evidence bearing on the relationship between the Society of Antiquaries and the women who contributed to it during a significant period when archaeology, through the work of such men as Samuel Lysons and Richard Colt Hoare, was beginning to emerge as a distinct field with its own conceptual and technical systems. It takes its departure from the first substantial appearance by a woman in the Society's publications in 1776, and continues until the accession of a female monarch, Victoria, in 1837, a period of just over sixty years. It explores what women did and what reception they received and assesses the significance of this within the wider processes of the development of an understanding of the past and the shaping of gender relationships through the medium of material culture, in a period that saw fundamental changes in many areas of intellectual and social life, including levels of material consumption and the sentiments surrounding consumerism.

ABSTRACT Eight strains of chemoorganotrophic bacteria were isolated from the water column of Lake Hoare, McMurdo Dry Valleys, Antarctica, using cold enrichment temperatures. The isolates were Alpha-, Beta-, and Gammaproteobacteria and Actinobacteria spp. All isolates grew at 0°C, and all but one grew at subzero temperatures characteristic of the water column of Lake Hoare. Growth temperature optima varied among isolates, but the majority showed optima near 15°C, indicative of cold-active phenotypes. One isolate was truly psychrophilic, growing optimally around 10°C and not above 20°C. Half of the isolates grew at 2% salt while the other half did not, and all but one isolate grew at 2 atm of O2. Our isolates are the first prokaryotes from the water column of Lake Hoare to be characterized phylogenetically and physiologically and show that cold-active species of at least two major phyla of Bacteria inhabit Lake Hoare.

Abstract. Failure in layers of buried surface hoar crystals (frost) can cause hazardous snow slab avalanches. Surface hoar crystals form on the snow surface and are sensitive to micro-meteorological conditions. In this study, the role of meteorological and terrain factors were investigated for three surface hoar layers in the Columbia Mountains of Canada. The distribution of crystals was observed over different elevations and aspects during 20 days of field observations. The same layers were modelled on a 2.5 km horizontal grid by forcing the snow cover model SNOWPACK with forecast weather data from a numerical weather prediction model. The moisture content of the air (i.e. absolute humidity) had the largest impact on modelled surface hoar growth, with warm and moist air being favourable. Surface hoar was most developed at certain elevation bands, usually corresponding to elevations with warm humid air, light winds, and cold surface temperatures. SNOWPACK simulations on virtual slopes systematically predicted smaller surface hoar on south-facing slopes. In the field, a complex combination of surface hoar and sun crusts were observed, suggesting the model did not adequately resolve the surface energy balance on slopes. Overall, a coupled weather–snow cover model could benefit avalanche forecasters by predicting surface hoar layers on a regional scale over different elevation bands.

Surface hoar crystals form on the snow surface and are sensitive to micro-meteorological conditions. In this study, the role of meteorological and terrain factors was investigated for three layers of surface hoar in the Columbia Mountains of Canada. The distribution of crystals over different elevations and aspects was observed on 20 days of field observations during a period of high pressure. The same layers were modelled over simplified terrain on a 2.5 km horizontal grid by forcing the snow cover model SNOWPACK with forecast weather data from a numerical weather prediction model. Modelled surface hoar growth was associated with warm air temperatures, high humidity, cold surface temperatures, and low wind speeds. Surface hoar was most developed in regions and elevation bands where these conditions existed, although strong winds at high elevations caused some model discrepancies. SNOWPACK simulations on virtual slopes systematically predicted smaller surface hoar on south-facing slopes. In the field, a complex combination of surface hoar and sun crusts were observed, suggesting the simplified model did not adequately resolve the surface energy balance on slopes. Overall, a coupled weather–snow cover model could benefit avalanche forecasters by predicting surface hoar layers on a regional scale over different elevation bands.

Abstract. Surface hoar size and location relate directly to avalanche initiation trigger points, and they do so in small-scale spatial distributions. Physically, surface hoar will grow where the snow surface is cold relative to the air and water vapour is plentiful. Vapour aside, snow cools at night primarily by longwave radiation emittance. Emittance can be restricted by clouds, trees, and terrain features. With 96 independent spatial point samples of surface hoar size, we show the extreme small-scale size variation that trees can create, ranging from 0 to 14 mm in an area of 402 m2. We relate this size variation to the effects of trees by using satellite photography to estimate the amount that trees impinge on sky view for each point. Though physically related to longwave escape, radiation balance can be as difficult to estimate as surface hoar size itself. Thus, we estimate point surface hoar size by expected maximum areal crystal size and dry terrain greyscale value only. We confirm this relation by using it at a different area and in a different formation cycle. There, its overall average error was 1.5 mm for an area with surface hoar sizes ranging from 0 to 7 mm.

AbstractThe continental regions of China are extensively covered by snow during winter. In this paper, the seasonal snow cover in the Tien Shan and Altay mountains is observed and analyzed, based on the characteristics of the dry-cold snow cover accumulating under the continental climatic conditions in northwest China. Compared with the humid-warm snow cover, the dry-cold snow cover is characterized mainly by small density, low water content, large temperature gradient, thick depth hoar, etc., and its metamorphism is dominated by the thermal exchange and the pressure of the overlying snow layers. According to the observed data, the solar radiation flux on the snow surface is dominated by a negative balance in the arid areas in China during the snow season; the albedo on the new-fallen-snow surface is up to 96%, and the transmission depth of shortwave radiation in dry-cold snow cover is 28 cm. During the snowmelt season in spring, the thickness of the depth hoar can occupy 80% of the whole snow cover.

A new species Eriocaulon shrirangii is described and illustrated here from Konkan region of Maharashtra, India. The new species is allied to E. belgaumensis with rosulate and linear leaves, length of peduncles, c. 2 mm across heads and cells of seed coat transversely elongated, aligned in vertical rows, but differs in its oblanceolate floral bracts; pedicellate male flowers; linear-lanceolate sepals of female flower, hairy at apex; hoary petals of female flower and appendages present on seeds.

Weak layers such as buried surface hoar or depth hoar frequently form the failure plane of slab avalanches. Therefore, the mechanical properties of such layers in relation to their snow structure have been investigated. Since it is difficult to transport samples containing a weak layer into cold rooms, the mechanical measurements have to be made in situ.We investigate strain-rate dependency of shear strength by measuring concurrently strength, deformation and acceleration, using a digital force gauge attached to a 0.05 m2 shear frame to which an accelerometer and a displacement sensor are fixed. In doing so, a dynamic force comparable to a driving skier is applied. The measurements cover a strain-rate range 10-2 to 1 s-1. The samples fail in a brittle manner. The shear-strength values cover the range 0.2–2.8 kPa. The dataset is also used to approximate the coefficient G, the shear modulus, for different weak layers.The snow structure has been analysed macroscopically in the field and for some layers representative snow samples have been extracted in order to prepare, in the cold laboratory, single-sided serial planes with cuts every 0.1 mm recorded by video. The analysis of these snow samples should have given the relation between some mechanical properties (strength, strain) and the structural properties. Due to basic problems in defining the connection between complex snow grains (e.g. surface hoar), we were unable to complete this part in due time. Only preliminary results on this aspect are presented here. Based on our long-term database, containing macroscopic structural and strength data of weak layers, a relationship between snow type and shear strength has been established.

Many animals hoard food, including humans, but despite its pervasiveness, little is known about the physiological mechanisms underlying this appetitive behavior. We summarize studies of food hoarding in humans and rodents with an emphasis on mechanistic laboratory studies of species where this behavior importantly impacts their energy balance (hamsters), but include laboratory rat studies although their wild counterparts do not hoard food. The photoperiod and cold can affect food hoarding, but food availability is the most significant environmental factor affecting food hoarding. Food-deprived/restricted hamsters and humans exhibit large increases in food hoarding compared with their fed counterparts, both doing so without overeating. Some of the peripheral and central peptides involved in food intake also affect food hoarding, although many have not been tested. Ad libitum-fed hamsters given systemic injections of ghrelin, the peripheral orexigenic hormone that increases with fasting, mimics food deprivation-induced increases in food hoarding. Neuropeptide Y or agouti-related protein, brain peptides stimulated by ghrelin, given centrally to ad libitum-fed hamsters, duplicates the early and prolonged postfood deprivation increases in food hoarding, whereas central melanocortin receptor agonism tends to inhibit food deprivation and ghrelin stimulation of hoarding. Central or peripheral leptin injection or peripheral cholecystokinin-33, known satiety peptides, inhibit food hoarding. Food hoarding markedly increases with pregnancy and lactation. Because fasted and/or obese humans hoard more food in general, and more high-density/high-fat foods specifically, than nonfasted and/or nonobese humans, understanding the mechanisms underlying food hoarding could provide another target for behavioral/pharmacological approaches to curb obesity.

Active frost protection methods may be expensive, but a correctly selected and operated system can provide more consistent crops and improved cash flow in years of potentially damaging cold events at postbudbreak stages of grape development. The selection of an active frost protection system depends on a number of factors, including the prevailing climatic conditions that occur during the spring season at the vineyard location, the costs associated with different frost control systems as well as considerations related to the reliability and relative simplicity of operating the equipment associated with each method. In winegrape production areas in North Carolina, hoar (white) frosts are the predominant cold threat in the postbudbreak period. A wind machine can be a very cost-effective investment on sites that are prone to a damaging frost event in 1 of 5 years or with a higher frequency of occurrence. However, wind machines have less overall usefulness in growing areas where there is also potential for black frosts (a more damaging radiational event than a hoar frost) and frosts/freezes (events with subfreezing temperatures and winds in the range of 2.2 to 4.5 m·s−1). For black frost events, a well-designed overvine sprinkling system can provide nearly 6 °C protection; sprinkling is also an appropriate management option for frost/freeze events. Windborne freezes are far less common at the postbudbreak stages but represent the most damaging type of cold event that can occur in eastern and midwestern winegrape regions in the United States. Methods that reliably delay budbreak (e.g., dormant oils, evaporative cooling with targeted sprinklers) may represent the best near-term opportunity for growers to decrease or avoid vine injury from freeze events such as the early April Easter freeze of 2007 that devastated grape vineyards through much of the midwest and southeastern United States.

Eriocaulon pandeyana from the Idukki district in Kerala is here described as a new species of Eriocaulaceae. It closely resembles E. ramnadense but is distinct by having oblong-lanceolate, lobed, acute, hyaline involucral bracts, oblanceolate, acuminate floral bracts, 3 sub-equal male petals, 3 unequal, slightly hoary female sepals and yellow, elliptic seeds with transversely elongated or isodiametric seed coat cells. The differences between the other similar species are also discussed. Since adequate data on abundance and distribution are lacking, the new species is provisionally listed under the category Data Deficient (DD) as per IUCN Red List Categories and Criteria.

Abstract The presence of a snowpack, which may last up to 9 months in the Arctic, can provide insulation from the cold winter temperature for small mammals living beneath it, such as lemmings. Since lemmings have to move through the snowpack during that period, it is important to better understand how the physical properties of snow affect the way they dig tunnels. Here, we tested 1) whether lemmings systematically dig in the snowpack at the ground level where they can find their food plants, and 2) whether they choose the softest snow layer in which to dig, which is usually the depth hoar layer in the arctic snowpack. We found 33 lemming tunnels in 2017 and 2018 by digging through the snow at the sites of arctic fox attacks on lemmings. Contrary to our expectation, almost all the tunnels (32/33) were found to be higher than ground level, probably because of the presence of obstacles (i.e., melt-freeze crusts or hummocks) at the base of the snowpack. As predicted, all tunnels were dug in the soft depth hoar layer, which had a lower density than snow layers below and above it. Lemmings also showed a preference to dig their tunnels at the top of the depth hoar, just below a hard snow layer. Systematically digging their tunnels in the lowest-density snow layer, regardless of its height in the snow pack, could be a strategy for lemmings to minimize energy expenditure, which could improve their survival and chances of reproducing in winter.

Nests, roosts, and dens are an important facet of life for many animals and often provide refuge from weather and predators. Reproduction, particularly lactation, is energetically expensive. Many small mammals form maternity colonies in sheltered locations, which provides protection for offspring and mitigates the cost of staying warm. However, lasiurine bats give birth in roosts that superficially appear to offer relatively little thermal buffer. Given the consequences of a cold environment on offspring growth and the high energetic demand of thermoregulating and lactating concurrently, choosing roosts with certain microclimatic properties would be beneficial. We investigated the influence of microclimate on roost selection by lactating hoary bats ( Lasiurus cinereus (Beauvois, 1796)), a solitary foliage-roosting species. We found that roosts chosen by bats offered shelter from the wind and exposure to sunlight, and consistently had an opening that faced south. We suggest that lactating L. cinereus choose roosts based largely on a microclimate that reduces convective cooling and increases radiant heating, thereby mitigating the cost of thermoregulation and promoting rapid growth of offspring.

Population declines along the lower-latitude edge of a species' range may be diagnostic of climate change. We report evidence that climate change has contributed to deteriorating reproductive success in a rapidly declining population of the grey jay ( Perisoreus canadensis ) at the southern edge of its range. This non-migratory bird of boreal and subalpine forest lives on permanent territories, where it hoards enormous amounts of food for winter and then breeds very early, under still-wintry conditions. We hypothesized that warmer autumns have increased the perishability of hoards and compromised subsequent breeding attempts. Our analysis confirmed that warm autumns, especially when followed by cold late winters, have led to delayed breeding and reduced reproductive success. Our findings uniquely show that weather months before the breeding season impact the timing and success of breeding. Warm autumns apparently represent hostile conditions for this species, because it relies on cold storage. Our study population may be especially vulnerable, because it is situated at the southern edge of the range, where the potential for hoard rot is most pronounced. This population's demise may signal a climate-driven range contraction through local extinctions along the trailing edge.

AbstractThis study provides a comparative analysis of the dormancy and germination mechanisms of the indehiscent fruits of hoary cress (Lepidium draba L.) and hairy whitetop (Lepidium appelianum Al-Shehbaz), two invasive weeds of the Brassicaceae. Germination assays comparing isolated seeds (manually removed from the fruits) and intact indehiscent fruits showed that the isolated seeds are nondormant and provided full germination for both species. In contrast to this, the species differed in the germination properties of their indehiscent fruits, in that L. appelianum fruits were nondormant, while the L. draba fruit coat (pericarp) conferred a coat-imposed dormancy. The pericarp of L. draba fresh fruit was water permeable, and neither mechanical scarification nor surface sterilization affected germination, supporting the concept that pericarp-mediated dormancy was not due to water impermeability or mechanical constraint. Washing of L. draba fruits with water, afterripening (dry storage), and treatment with gibberellin (GA) stimulated the germination of this species, all of which are indicative of physiological dormancy. Analyses of endogenous abscisic acid (ABA) and GA levels combined with treatment experiments with wash water from fresh and afterripened L. draba pericarps and with ABA dose–response quantification of germination revealed that ABA is a key component of a pericarp-mediated chemical dormancy in this species. Consistent with this, pericarp ABA levels decreased during afterripening and upon fruit washing, and isolated fresh or afterripened seeds did not differ in their ABA sensitivities. The possible roles of the ABA-mediated pericarp dormancy for the germination ecophysiology and weed management of these species are discussed.

AbstractSnow-cover models are used in many applications in today’s snow and ice research. Although physically based models allow the evolution of the internal structure of the snow cover to be followed very closely a quantitative and objective description of the layer texture’s evolution in snow subjected to large temperature gradients is still required, in order to both improve and verify existing snow-cover models. Based on experiments done in the cold laboratory as well as on field observations on snow subjected to kinetic-growth metamorphism, we present new results on the quantification of texture-related parameters. Problems such as linking objective laboratory work to pragmatic field observations and finding a reproducible method to measure shape-related parameters are discussed. Finally a new shape parameter is proposed, zero curvature, which differentiates well between depth hoar, faceted crystals and snow types with rounded grains. It also shows a pronounced dependence on temperature gradient.

AbstractDielectric measurements of snow were carried out in the temperature range –15° to 0°C and in the frequency range 50 Hz to 5 MHz. The snow samples (about 400 kg m–3 density) used were stored snow (average particle size: 2 mm) and hoar-frost (particle size: <1 to 5 mm). The frequency characteristics of dielectric parameters showed a dielectric dispersion (Davidson-Cole type) around 30 kHz and a low-frequency dielectric dispersion (Cole-Cole circular law type). The a.c. conductivity showed a dielectric dispersion around 30 kHz and two characteristic constant values in the frequency ranges above 1 MHz and below 100 Hz (the high-frequency conductivity σ∞ and the low-frequency conductivity σLOW). The low-frequency conductivity σLOW showed a peak at about –2°C. This behavior has never been noted by previous researchers. The σLOW showed an activation energy of about 1 eV below –5°C. This means that the σLOW is mainly caused by a surface conduction. The activation energy increased with increasing temperature above –5°C. This means that the σLOW in this temperature range is affected by the quasi-liquid layer on ice surfaces. The σLOW above –2°C decreased with increasing temperature. The apparently curious behavior near the melting temperature is attributed to the numerous free ice surfaces within the porous snow. This conclusion was reached because our measurements without the free ice surfaces showed no such conductivity peaks for solid polycrystalline ice samples and for snow samples soaked with kerosene in the cooling process.

The paper analyzes the climatic anomalies in Oltenia that occurred in spring 2020. After the Mediterranean winter of 2019-2020, the spring was excessively early on large areas, and on average very early. As a result, the vegetation started to develop very early, since the first part of March, and the flowering of the early fruit trees took place in the first half of March. In the first two months of spring there were 31 days in which the daily minimum temperatures were negative and there was hoar and frost on the soil surface. Thus, in March, minimum negative temperatures were registered in the intervals: 1.III, 6.III, 16-19.III, 23-31.III, ie 15 days. In April, minimum negative temperatures were registered in the intervals: 1-10.IV, 15-16. IV, 23-25.IV and 27.IV, totaling 16 days. The cooling of the weather culminated with the interval 22-25.III, in which the highest amounts of precipitation were registered in March but also in the whole cold season 2019-2020. There were blizzards that deposited a consistent layer of snow and banks formed, lasting 4 days being the longest in the cold season 2019-2020. The intense cooling of the weather after the warm winters are destructive climatic anomalies. The paper is part of an extensive series of studies on climate variability in southwestern Romania (Oltenia) in the context of climate change (I. Marinică, 2006, 2008; Marinicǎ I., Marinicǎ Andreea Floriana, 2016).

ABSTRACTThe morphology of englacial drainage networks and their temporal evolution are poorly characterised, particularly within cold ice masses. At present, direct observations of englacial channels are restricted in both spatial and temporal resolution. Through novel use of a terrestrial laser scanning (TLS) system, the interior geometry of an englacial channel in Austre Brøggerbreen, Svalbard, was reconstructed and mapped. Twenty-eight laser scan surveys were conducted in March 2016, capturing the glacier surface around a moulin entrance and the uppermost 122 m reach of the adjoining conduit. The resulting point clouds provide detailed 3-D visualisation of the channel with point accuracy of 6.54 mm, despite low (<60%) overall laser returns as a result of the physical and optical properties of the clean ice, snow, hoar frost and sediment surfaces forming the conduit interior. These point clouds are used to map the conduit morphology, enabling extraction of millimetre-to-centimetre scale geometric measurements. The conduit meanders at a depth of 48 m, with a sinuosity of 2.7, exhibiting teardrop shaped cross-section morphology. This improvement upon traditional surveying techniques demonstrates the potential of TLS as an investigative tool to elucidate the nature of glacier hydrological networks, through reconstruction of channel geometry and wall composition.

Soils at a Long Term Ecological Research site near Lake Hoare in Taylor Valley, Antarctica, were investigated during November/December 1999. The soils alongside 6 experimental plots at the research site were described, repeatedly sampled over a 17-day period, and the gravimetric water content, particle size, and conductivity determined daily. At one nearby location, the soil water content was repeatedly measured after a plot irrigation, while at another, the water content of soil adjacent to a snow patch was repeatedly measured to determine the rate of water loss during thawing of snow. Soils at 2 sites at higher elevations outside the research area were also examined for comparison.The soils at the experimental plots were generally similar but differed in stoniness, the presence of occasional silty layers, and the depth to ice-cemented ground. Water contents (gravimetric) of surface horizons were <0.5% and increased with depth through the active layer to 12% or greater in the ice-cemented permafrost. There were small variations in the water content of surface horizons over the 17-day sampling period with larger variations at depth. A few siltier horizons had higher water contents. The water content profiles and <2 mm% particle size trends were broadly similar for all the sites. Conductivities were low, except in silty horizons where values were markedly higher. At the irrigated site, water was progressively lost over the first 9 days, after which values were close to those at unirrigated sites. There was a less marked loss of water from the soil alongside the thawing snow patch but an increased loss after all snow had thawed. The higher elevation soils outside the experimental area were more weathered and had higher salinities indicating a significantly greater soil age.Small changes in water content in the surface horizons appeared to be related to changing weather conditions, whereas at greater soil depth, changes in the water content corresponded with the increasing thawing depth. The results illustrate the dynamic nature of soil moisture over short periods of time in Antarctic Cold Desert soils.

Every year World Thyroid Day is observed on May 25 to spread awareness on the disorders of thyroid gland and their prevention. Yet the increase in thyroid problems is unabated. In fact, thyroid is one of the most important endocrine glands that regulates all most all body functions of human beings. It synthesizes and secrets 2 main hormones, thyroxine(T4) and tri-iodothyronine(T3), both being regulated by thyroid-stimulating hormone (TSH). While the whole amount of circulating T4 is produced by the thyroid gland itself, T3 is mostly generated in liver and kidney by peripheral mono-deiodination of T4 with the help of an enzyme, 5'-deiodinase (5' D). Thyroid hormones are vital for the well-being of a person and their abnormal levels lead to health problems. People with thyroid abnormalities suffer either from hypo-functioning (hypothyroidism) or from hyper-functioning (hyperthyroidism) of the gland. However, most common thyroid problem is hypothyroidism and females suffer more from this as compared to males. According to Chiovato et al. (2019), hypothyroidism affects about 5% of the general population and 5% more are believed to be sufferers, but undiagnosed. Primary hypothyroidism is normally diagnosed with low serum thyroid hormones and high TSH concentrations than the normal reference ranges. Symptoms of hypothyroidism include intolerance to cold, mild to moderate weight gain, dry skin, puffiness of the body, peri-orbital swelling, chronic fatigue, constipation, depression, hoarse voice and menstrual irregularities.The consequences of untreated or under-treated hypothyroidism include cretinism, myxoedema and goitre, even coronary artery disease.

AbstractObservations of temperature maxima at about 10 cm depth in cold Antarctic snow during summer have previously been explained by proposing that solar heating is distributed with depth whereas thermal infrared cooling is localized at the surface (the “solid-state greenhouse”). An increase in temperature from the surface to 10 cm depth(ΔΤ≈ 4 K) found by Rusin (1961) on the Antarctic Plateau was successfully reproduced by Schlatter (1972) in a combined radiative-transfer and heat-transfer model. However, when we improve the model’s spectral resolution, solving for solar radiative fluxes separately in 118 wavelength bands instead of just one “average” wavelength,ΔΤshrinks to 0.2 Κ and moves toward the surface, indicating that the solid-state greenhouse is largely an artifact of inadequate spectral resolution. The agreement between Schlatter’s broad-band model and Rusin’s measurement suggests that the measurement is inaccurate, perhaps due to solar heating of the buried thermistors. Similar broad-band models which have been applied to the icy surface of Jupiter’s satellite Europa are also shown to overestimate the solid-state greenhouse by a factor of about 6.The reason that the solid-state greenhouse effect is insignificant in the case of Antarctic snow is that the wavelengths which do penetrate deeply into snow (visible light) are essentially not absorbed and are scattered back to the surface, whereas the wavelengths that are absorbed by snow (near-infrared) are absorbed in the top few millimeters.The conditions needed to obtain a significant solid-state greenhouse are examined. The phenomenon becomes important if the scattering coefficient is small (as in blue ice) or if the thermal conductivity is low (as in low-density snow, such as near-surface depth hoar).

Целью представленной работы является определение динамики изменения серебряных монет Золотой Орды и Болгарского улуса второй половины XIV – первой трети XV вв. в контексте исторических событий и катаклизмов путем анализа нумизматического материала и определения химического состава. В изученную выборку из 23 фрагментов серебряных денег вошли монеты Болгарского чекана, подражания джучидским дангам, обрезанные и надчеканенные монеты, а также в качестве элемента сравнения – монета Крымского ханства. Концентрация элементов в металле образцов определялась двумя независимыми аналитическими методами – неразрушающим рентгенофлуоресцентным (XRF) и эмиссионным спектральным (ESA). XRF-анализ проводился как на поверхности, так и на изломе монет. Сравнение результатов по содержанию основных компонентов монетных сплавов выявило различие в концентрации серебра и меди, определенных на поверхности и изломе. Результаты ESA и XRF (на изломе) показали хорошую сопоставимость и позволили выявить тенденции в изменении химического состава в зависимости от времени и правителя.

Lianas (woody climbers) are relatively underexplored life forms of many forests, which predominantly forms tropical forests and provide food and shelter to a variety of animals. A study on flower-pollinator interactions in Roxb. was conducted in the Caesalpinia cucullatatropical rain forest of Indo-Burma hot spot at Tanhril area of Aizawl district of Mizoram. Floral visitors of were monitored and C. cucullatarecorded during 24 field days, four to six hour per day with a total of about one hundred hours during the flowering season of November–December, 2016. The flowers of were found to be visited by three insect species belonging three families; nine C. cucullata passeriformes birds belonging eight families and one Hoary-bellied Himalayan squirrel (Irrawaddy squirrel) belonging family Scuiridae. Birds and squirrel mainly visited the flowers in morning hours while butterflies and bee exhibited diurnal pattern of foraging. The results revealed s that the bird pollination is supported by butterflies in . The flowers of would be excellent food resource to the dependent C. cucullata C. cucullata animal species during dry cold period in the extreme tropical sloppy mountain forest site when availability of floral resource is very scarce. Therefore, could be a valuable liana species for the conservation of valuable species of insects, birds and squirrels.

In spite of seleetion for thousands of years, the avocado is still a poorly domesticated tree in the early stages of adaptation to an orehard environment. Cultivars based on Guatemalan and Mexican germplasm, for the subtropics and Mediterranean elimates, have only been available since the 1920's, and even in the best growing conditions the yield barrier of 30 t.ha-1 is hard to breaeh. Tropical "West Indian" (Iowland) avocado eultivars and produetion teehnology is less well developed. Orehard performance is therefore still largely influenced by evolutionary hangovers and constraints. For "subtropical" types, we have to deal with the residual survival strategies of a late-successional, K-seleeted, small-gap colonizing mountain eloud forest tree. These inelude potentially vigorous vegetative growth in flushes, counter-produetive to flowering and fruiting; delayed and typically irregular (mast) fruiting; unnecessarily profuse flowering in late'winter synchronized by winter cold and drought; short-lived shade-adapted leaves bome in creasingly further from the trunk on the tree periphery; energy-expensive fruits for large dispersal agents, hence the exhaustive nature of eropping on reserves, espeeially in large trees; and the tree's strategy to effieiently hoard, store and recyele carbohydrate and mineral reserves (hence "mineral-eheap" fruiting). Physiological attributes inelude potentially rapid C assimilation, but reduced photosynthesis under shade, water of Phytophthora stress; reasonable drought tolerance which however is at the expense of C assimilation and leaf effieiency; and the poorly researehed dependence on perseitol rather than sucrose as the main translocation sugar. Manipulation implications center around canopy/tree size/light management and the alleviation of stress at criticar times, to optimize C gain and allocation to fruiting on a sustainable basis. The prime need remains breeding for more manageable seion and rootstock combinations.

The Lepidium draba or white tope also known as hoary cress belongs to family Brassicaceae, has been known as one of the perennial herbs which grow normally from seeds and also produced horizontal long creeping roots. It normally grows as a weed plant in farm fields. The present study was conducted to find out the antibacterial and antioxidant activities along with the plant traits of Lepidium draba. The shoot, root and inflorescence extracts were taken through using ethanol, water and n-hexan as extraction solvents. It was found from our studies that the plant extracts were heaving alkaloids, saponins, flavonoids, coumarins, anthocyans, quinons, steroids, sterols and terpenoids as potential phenolic compounds. The bacterial strains including Escherichia coli, Klebsiella pneumonia and Staphylococcus aureus were cultured to access the antibacterial activities of plant extracts. The higher antibacterial activity was reported from n-hexan extract which indicate that the n-hexan extract may be used for extracting phytochemicals to be used as potential antibacterial biomedicines. The water extract showed higher antioxidant activities as compared with ethanol and n-hexan extracts which indicated that the use of water extract may be as a useful antioxidant under stress conditions, may also have anticancer activities. The lower coefficient of variation was recorded for all of the studied traits which indicated the consistency of results and reliability of selecting plants from various locations. There was significant and positive correlation among plant height with inflorescence weight, leaf area and leaf length, the inflorescence weight showed positive correlation with plant height, lea length and leaf area. There was higher contribution of plant height while leaf area contributed lower and negatively towards fresh plant weight. We have concluded from our study that the Lepidium draba plant extract showed antibacterial and antioxidant activities through using ethanol, water and n-hexan as extraction solvents. The significant correlation and regression associations indicated that the plants can tolerate harsh environmental conditions.

There is, in our sense of place, little cognisance of what lies underground. Yet our sense of place, instinctive, unconscious, primeval, has its own underground: the secret spaces which mirror our insides; the world beneath the skin. Our roots lie beneath the ground, with the minerals and the dead. (Hughes 83) The-Home-and-Away-Game Imagine the earth-grounded, “diagrammatological” trajectory of a footballer who as one member of a team is psyching himself up before the start of a game. The siren blasts its trumpet call. The footballer bursts out of the pavilion (where this psyching up has taken place) to engage in the opening bounce or kick of the game. And then: running, leaping, limping after injury, marking, sliding, kicking, and possibly even passing out from concussion. Finally, the elation accompanying the final siren, after which hugs, handshakes and raised fists conclude the actual match on the football oval. This exit from the pavilion, the course the player takes during the game itself, and return to the pavilion, forms a combination of stasis and movement, and a return to exhausted stasis again, that every player engages with regardless of the game code. Examined from a “diagrammatological” perspective, a perspective Rowan Wilken (following in the path of Gilles Deleuze and W. J. T. Mitchell) understands as “a generative process: a ‘metaphor’ or way of thinking — diagrammatic, diagrammatological thinking — which in turn, is linked to poetic thinking” (48), this footballer’s scenario arises out of an aerial perspective that depicts the actual spatial trajectory the player takes during the course of a game. It is a diagram that is digitally encoded via a sensor on the footballer’s body, and being an electronically encoded diagram it can also make available multiple sets of data such as speed, heartbeat, blood pressure, maybe even brain-wave patterns. From this limited point of view there is only one footballer’s playing trajectory to consider; various groupings within the team, the whole team itself, and the diagrammatological depiction of its games with various other teams might also be possible. This singular imagining though is itself an actuality: as a diagram it is encoded as a graphic image by a satellite hovering around the earth with a Global Positioning System (GPS) reading the sensor attached to the footballer which then digitally encodes this diagrammatological trajectory for appraisal later by the player, coach, team and management. In one respect, this practice is another example of a willing self-surveillance critical to explaining the reflexive subject and its attribute of continuous self-improvement. According to Docker, Official Magazine of the Fremantle Football Club, this is a technique the club uses as a part of game/play assessment, a system that can provide a “running map” for each player equipped with such a tracking device during a game. As the Fremantle Club’s Strength and Conditioning Coach Ben Tarbox says of this tactic, “We’re getting a physiological profile that has started to build a really good picture of how individual players react during a game” (21). With a little extra effort (and some sizeable computer processing grunt) this two dimensional linear graphic diagram of a footballer working the football ground could also form the raw material for a three-dimensional animation, maybe a virtual reality game, even a hologram. It could also be used to sideline a non-performing player. Now try another related but different imagining: what if this diagrammatological trajectory could be enlarged a little to include the possibility that this same player’s movements could be mapped out by the idea of home-and-away games; say over the course of a season, maybe even a whole career, for instance? No doubt, a wide range of differing diagrammatological perspectives might suggest themselves. My own particular refinement of this movement/stasis on the footballer’s part suggests my own distinctive comings and goings to and from my own specific piece of home country. And in this incessantly domestic/real world reciprocity, in this diurnally repetitive leaving and coming back to home country, might it be plausible to think of “Home as Capital of the Region”? If, as Walter Benjamin suggests in the prelude to his monumental Arcades Project, “Paris — the Capital of the Nineteenth Century,” could it be that both in and through my comings and goings to and from this selfsame home country, my own burgeoning sense of regionality is constituted in every minute-by-minutiae of lived experience? Could it be that this feeling about home is manifested in my every day-to-night manoeuvre of home-and-away-and-away-and-home-making, of every singular instance of exit, play/engage, and the return home? “Home, Capital of the Region” then examines the idea that my home is that part of the country which is the still-point of eternal return, the bedrock to which I retreat after the daily grind, and the point from which I start out and do it all again the next day. It employs, firstly, this ‘diagrammatological’ perspective to illustrate the point that this stasis/movement across country can make an electronic record of my own psychic self-surveillance and actualisation in-situ. And secondly, the architectural plan of the domestic home (examined through the perspective of critical regionalism) is used as a conduit to illustrate how I am physically embedded in country. Lastly, intermingling these digressive threads is chora, Plato’s notion of embodied place and itself an ancient regional rendering of this eternal return to the beginning, the place where the essential diversity of country decisively enters the soul. Chora: Core of Regionality Kevin Lynch writes that, “Our senses are local, while our experience is regional” (10), a combination that suggests this regional emphasis on home-and-away-making might be a useful frame of reference (simultaneously spatiotemporal, both a visceral and encoded communication) for me to include as a crucial vector in my own life-long learning package. Regionality (as, variously, a sub-generic categorisation and an extension/concentration of nationality, as well as a recently re-emerged friend/antagonist to a global understanding) infuses my world of home with a grounded footing in country, one that is a site of an Eternal Return to the Beginning in the micro-world of the everyday. This is a point John Sallis discusses at length in his analysis of Plato’s Timaeus and its founding notion of regionality: chora. More extended absences away from home-base are of course possible but one’s return to home on most days and for most nights is a given of post/modern, maybe even of ancient everyday experience. Even for the continually shifting nomad, nightfall in some part of the country brings the rest and recreation necessary for the next day’s wanderings. This fundamental question of an Eternal Return to the Beginning arises as a crucial element of the method in Plato’s Timaeus, a seemingly “unstructured” mythic/scientific dialogue about the origins and structure of both the psychically and the physically implaced world. In the Timaeus, “incoherence is especially obvious in the way the natural sequence in which a narrative would usually unfold is interrupted by regressions, corrections, repetitions, and abrupt new beginnings” (Gadamer 160). Right in the middle of the Timaeus, in between its sections on the “Work of Reason” and the “Work of Necessity”, sits chora, both an actual spatial and bodily site where my being intersects with my becoming, and where my lived life criss-crosses the various arts necessary to articulating a recorded version of that life. Every home is a grounded chora-logical timespace harness guiding its occupant’s thoughts, feelings and actions. My own regionally implaced chora (an example of which is the diagrammatological trajectory already outlined above as my various everyday comings and goings, of me acting in and projecting myself into context) could in part be understood as a graphical realisation of the extent of my movements and stationary rests in my own particular timespace trajectory. The shorthand for this process is ‘embedded’. Gregory Ulmer writes of chora that, “While chorography as a term is close to choreography, it duplicates a term that already exists in the discipline of geography, thus establishing a valuable resonance for a rhetoric of invention concerned with the history of ‘place’ in relation to memory” (Heuretics 39, original italics). Chorography is the geographic discipline for the systematic study and analysis of regions. Chora, home, country and regionality thus form an important multi-dimensional zone of interplay in memorialising the game of everyday life. In light of these observations I might even go so far as to suggest that this diagrammatological trajectory (being both digital and GPS originated) is part of the increasingly electrate condition that guides the production of knowledge in any global/regional context. This last point is a contextual connection usefully examined in Alan J. Scott’s Regions and the World Economy: The Coming Shape of Global Production, Competition, and Political Order and Michael Storper’s The Regional World: Territorial Development in a Global Economy. Their analyses explicitly suggest that the symbiosis between globalisation and regionalisation has been gathering pace since at least the end of World War Two and the Bretton Woods agreement. Our emerging understanding of electracy also happens to be Gregory Ulmer’s part-remedy for shifting the ground under the intense debates surrounding il/literacy in the current era (see, in particular, Internet Invention). And, for Tony Bennett, Michael Emmison and John Frow’s analysis of “Australian Everyday Cultures” (“Media Culture and the Home” 57–86), it is within the home that our un.conscious understanding of electronic media is at its most intense, a pattern that emerges in the longer term through receiving telegrams, compiling photo albums, listening to the radio, home- and video-movies, watching the evening news on television, and logging onto the computer in the home-office, media-room or home-studio. These various generalisations (along with this diagrammatological view of my comings and goings to and from the built space of home), all point indiscriminately to a productive confusion surrounding the sedentary and nomadic opposition/conjunction. If natural spaces are constituted in nouns like oceans, forests, plains, grasslands, steppes, deserts, rivers, tidal interstices, farmland etc. (and each categorisation here relies on the others for its existence and demarcation) then built space is often seen as constituting its human sedentary equivalent. For Deleuze and Guatteri (in A Thousand Plateaus, “1227: Treatise on Nomadology — The War Machine”) these natural spaces help instigate a nomadic movement across localities and regions. From a nomadology perspective, these smooth spaces unsettle a scientific, numerical calculation, sometimes even aesthetic demarcation and order. If they are marked at all, it is by heterogenous and differential forces, energised through constantly oscillating intensities. A Thousand Plateaus is careful though not to elevate these smooth nomadic spaces over the more sedentary spaces of culture and power (372–373). Nonetheless, as Edward S. Casey warns, “In their insistence on becoming and movement, however, the authors of A Thousand Plateaus overlook the placial potential of settled dwelling — of […] ‘built places’” (309, original italics). Sedentary, settled dwelling centred on home country may have a crust of easy legibility and order about it but it also formats a locally/regionally specific nomadic quality, a point underscored above in the diagrammatological perspective. The sedentary tendency also emerges once again in relation to home in the architectural drafting of the domestic domicile. The Real Estate Revolution When Captain Cook planted the British flag in the sand at Botany Bay in 1770 and declared the country it spiked as Crown Land and henceforth will come under the ownership of an English sovereign, it was also the moment when white Australia’s current fascination with real estate was conceived. In the wake of this spiking came the intense anxiety over Native Title that surfaced in late twentieth century Australia when claims of Indigenous land grabs would repossess suburban homes. While easily dismissed as hyperbole, a rhetorical gesture intended to arouse this very anxiety, its emergence is nonetheless an indication of the potential for political and psychic unsettling at the heart of the ownership and control of built place, or ‘settled dwelling’ in the Australian context. And here it would be wise to include not just the gridded, architectural quality of home-building and home-making, but also the home as the site of the family romance, another source of unsettling as much as a peaceful calming. Spreading out from the boundaries of the home are the built spaces of fences, bridges, roads, railways, airport terminals (along with their interconnecting pathways), which of course brings us back to the communications infrastructure which have so often followed alongside the development of transport infrastructure. These and other elements represent this conglomerate of built space, possibly the most significant transformation of natural space that humanity has brought about. For the purposes of this meditation though it is the more personal aspect of built space — my home and regional embeddedness, along with their connections into the global electrosphere — that constitutes the primary concern here. For a sedentary, striated space to settle into an unchallenged existence though requires a repression of the highest order, primarily because of the home’s proximity to everyday life, of the latter’s now fading ability to sometimes leave its presuppositions well enough alone. In settled, regionally experienced space, repressions are more difficult to abstract away, they are lived with on a daily basis, which also helps to explain the extra intensity brought to their sometimes-unsettling quality. Inversely, and encased in this globalised electro-spherical ambience, home cannot merely be a place where one dwells within avoiding those presuppositions, I take them with me when I travel and they come back with me from afar. This is a point obliquely reflected in Pico Iyer’s comment that “Australians have so flexible a sense of home, perhaps, that they can make themselves at home anywhere” (185). While our sense of home may well be, according to J. Douglas Porteous, “the territorial core” of our being, when other arrangements of space and knowledge shift it must inevitably do so as well. In these shifts of spatial affiliation (aided and abetted by regionalisation, globalisation and electronic knowledge), the built place of home can no longer be considered exclusively under the illusion of an autonomous sanctuary wholly guaranteed by capitalist property relations, one of the key factors in its attraction. These shifts in the cultural, economic and psychic relation of home to country are important to a sense of local and regional implacement. The “feeling” of autonomy and security involved in home occupation and/or ownership designates a component of this implacement, a point leading to Eric Leed’s comment that, “By the sixteenth century, literacy had become one of the definitive signs — along with the possession of property and a permanent residence — of an independent social status” (53). Globalising and regionalising forces make this feeling of autonomy and security dynamic, shifting the ground of home, work-place practices and citizenship allegiances in the process. Gathering these wide-ranging forces impacting on psychic and built space together is the emergence of critical regionalism as a branch of architectonics, considered here as a theory of domestic architecture. Critical Regionality Critical regionalism emerged out of the collective thinking of Liane Lefaivre and Alexander Tzonis (Tropical Architecture; Critical Regionalism), and as these authors themselves acknowledge, was itself deeply influenced by the work of Lewis Mumford during the first part of the twentieth century when he was arguing against the authority of the international style in architecture, a style epitomised by the Bauhaus movement. It is Kenneth Frampton’s essay, “Towards a Critical Regionalism: Six Points for an Architecture of Resistance” that deliberately takes this question of critical regionalism and makes it a part of a domestic architectonic project. In many ways the ideas critical regionalism espouses can themselves be a microcosm of this concomitantly emerging global/regional polis. With public examples of built-form the power of the centre is on display by virtue of a building’s enormous size and frequently high-cultural aesthetic power. This is a fact restated again and again from the ancient world’s agora to Australia’s own political bunker — its Houses of Parliament in Canberra. While Frampton discusses a range of aspects dealing with the universal/implaced axis across his discussion, it is points five and six that deserve attention from a domestically implaced perspective. Under the sub-heading, “Culture Versus Nature: Topography, Context, Climate, Light and Tectonic Form” is where he writes that, Here again, one touches in concrete terms this fundamental opposition between universal civilization and autochthonous culture. The bulldozing of an irregular topography into a flat site is clearly a technocratic gesture which aspires to a condition of absolute placelessness, whereas the terracing of the same site to receive the stepped form of a building is an engagement in the act of “cultivating” the site. (26, original italics) The “totally flat datum” that the universalising tendency sometimes presupposes is, within the critical regionalist perspective, an erroneous assumption. The “cultivation” of a site for the design of a building illustrates the point that built space emerges out of an interaction between parallel phenomena as they contrast and/or converge in a particular set of timespace co-ordinates. These are phenomena that could include (but are not limited to) geomorphic data like soil and rock formations, seismic activity, inclination and declension; climatic considerations in the form of wind patterns, temperature variations, rainfall patterns, available light and dark, humidity and the like; the building context in relation to the cardinal points of north, south, east, and west, along with their intermediary positions. There are also architectural considerations in the form of available building materials and personnel to consider. The social, psychological and cultural requirements of the building’s prospective in-dwellers are intermingled with all these phenomena. This is not so much a question of where to place the air conditioning system but the actuality of the way the building itself is placed on its site, or indeed if that site should be built on at all. A critical regionalist building practice, then, is autochthonous to the degree that a full consideration of this wide range of in-situ interactions is taken into consideration in the development of its design plan. And given this autochthonous quality of the critical regionalist project, it also suggests that the architectural design plan itself (especially when it utilised in conjunction with CAD and virtual reality simulations), might be the better model for designing electrate-centred projects rather than writing or even the script. The proliferation of ‘McMansions’ across many Australian suburbs during the 1990s (generally, oversized domestic buildings designed in the abstract with little or no thought to the above mentioned elements, on bulldozed sites, with powerful air-conditioning systems, and no verandas or roof eves to speak of) demonstrates the continuing influence of a universal, centralising dogma in the realm of built place. As summer temperatures start to climb into the 40°C range all these air-conditioners start to hum in unison, which in turn raises the susceptibility of the supporting infrastructure to collapse under the weight of an overbearing electrical load. The McMansion is a clear example of a built form that is envisioned more so in a drafting room, a space where the architect is remote-sensing the locational specificities. In this envisioning (driven more by a direct line-of-sight idiom dominant in “flat datum” and economic considerations rather than architectural or experiential ones), the tactile is subordinated, which is the subject of Frampton’s sixth point: It is symptomatic of the priority given to sight that we find it necessary to remind ourselves that the tactile is an important dimension in the perception of built form. One has in mind a whole range of complementary sensory perceptions which are registered by the labile body: the intensity of light, darkness, heat and cold; the feeling of humidity; the aroma of material; the almost palpable presence of masonry as the body senses it own confinement; the momentum of an induced gait and the relative inertia of the body as it traverses the floor; the echoing resonance of our own footfall. (28) The point here is clear: in its wider recognition of, and the foregrounding of my body’s full range of sensate capacities in relation to both natural and built space, the critical regionalist approach to built form spreads its meaning-making capacities across a broader range of knowledge modalities. This tactility is further elaborated in more thoroughly personal ways by Margaret Morse in her illuminating essay, “Home: Smell, Taste, Posture, Gleam”. Paradoxically, this synaesthetic, syncretic approach to bodily meaning-making in a built place, regional milieu intensely concentrates the site-centred locus of everyday life, while simultaneously, the electronic knowledge that increasingly underpins it expands both my body’s and its region’s knowledge-making possibilities into a global gestalt, sometimes even a cosmological one. It is a paradoxical transformation that makes us look anew at social, cultural and political givens, even objective and empirical understandings, especially as they are articulated through national frames of reference. Domestic built space then is a kind of micro-version of the multi-function polis where work, pleasure, family, rest, public display and privacy intermingle. So in both this reduction and expansion in the constitution of domestic home life, one that increasingly represents the location of the production of knowledge, built place represents a concentration of energy that forces us to re-imagine border-making, order, and the dynamic interplay of nomadic movement and sedentary return, a point that echoes Nicolas Rothwell’s comment that “every exile has in it a homecoming” (80). Albeit, this is a knowledge-making milieu with an expanded range of modalities incorporated and expressed through a wide range of bodily intensities not simply cognitive ones. Much of the ambiguous discontent manifested in McMansion style domiciles across many Western countries might be traced to the fact that their occupants have had little or no say in the way those domiciles have been designed and/or constructed. In Heidegger’s terms, they have not thought deeply enough about “dwelling” in that building, although with the advent of the media room the question of whether a “building” securely borders both “dwelling” and “thinking” is now open to question. As anxieties over border-making at all scales intensifies, the complexities and un/sureties of natural and built space take ever greater hold of the psyche, sometimes through the advance of a “high level of critical self-consciousness”, a process Frampton describes as a “double mediation” of world culture and local conditions (21). Nearly all commentators warn of a nostalgic, romantic or a sentimental regionalism, the sum total of which is aimed at privileging the local/regional and is sometimes utilised as a means of excluding the global or universal, sometimes even the national (Berry 67). Critical regionalism is itself a mediating factor between these dispositions, working its methods and practices through my own psyche into the local, the regional, the national and the global, rejecting and/or accepting elements of these domains, as my own specific context, in its multiplicity, demands it. If the politico-economic and cultural dimensions of this global/regional world have tended to undermine the process of border-making across a range of scales, we can see in domestic forms of built place the intense residue of both their continuing importance and an increased dependency on this electro-mediated world. This is especially apparent in those domiciles whose media rooms (with their satellite dishes, telephone lines, computers, television sets, games consuls, and music stereos) are connecting them to it in virtuality if not in reality. Indeed, the thought emerges (once again keeping in mind Eric Leed’s remark on the literate-configured sense of autonomy that is further enhanced by a separate physical address and residence) that the intense importance attached to domestically orientated built place by globally/regionally orientated peoples will figure as possibly the most viable means via which this sense of autonomy will transfer to electronic forms of knowledge. If, however, this here domestic habitué turns his gaze away from the screen that transports me into this global/regional milieu and I focus my attention on the physicality of the building in which I dwell, I once again stand in the presence of another beginning. This other beginning is framed diagrammatologically by the building’s architectural plans (usually conceived in either an in-situ, autochthonous, or a universal manner), and is a graphical conception that anchors my body in country long after the architects and builders have packed up their tools and left. This is so regardless of whether a home is built, bought, rented or squatted in. Ihab Hassan writes that, “Home is not where one is pushed into the light, but where one gathers it into oneself to become light” (417), an aphorism that might be rephrased as follows: “Home is not where one is pushed into the country, but where one gathers it into oneself to become country.” For the in-and-out-and-around-and-about domestic dweller of the twenty-first century, then, home is where both regional and global forms of country decisively enter the soul via the conduits of the virtuality of digital flows and the reality of architectural footings.
