In this paper, we have studied the effects of retardation time of non-Newtonian Oldroyd-B type fluid driven by Helmholtz-Smoluchowski velocity in a micro-channel. The potential electric field is applied along the length of the micro-channel describing by the Poisson–Boltzmann equation. The governing model equation was solved analytically using the classical method of partial differential equations. Analytical solution was simulated with the help of MATHEMATICA software and the graphical results for various physical flow parameters were analyzed. Results shows that for larger values of retardation time of a viscoelastic fluid the higher the viscoelastic effect of the fluid and this makes it to need more time for the stress to respond to deformation. Also, the electrokinetic width of micro-channel play a vital rule on the performance of velocity distribution.

It is well known that an increased viscosity slows down fluid dynamics. Here we show that this intuitive rule is not general and can fail for liquids flowing in confined liquid-repellent systems. A gravity-driven, highly viscous glycerol droplet inside a sealed superhydrophobic capillary is moving more than 10 times faster than a water droplet with three-orders-of-magnitude lower viscosity. Using tracer particles, we show that the low-viscosity droplets are rapidly rotating internally, with flow velocities greatly exceeding the center-of-mass velocity. This is in stark contrast to the faster moving high-viscosity droplets with nearly vanishing internal flows. The anomalous viscosity-enhanced flow is caused by a viscosity-suppressed deformation of the droplet-air interface and a hydro- and aerodynamic coupling between the droplet and the air trapped within the micro/nanostructures (plastron). Our work demonstrates the unexpected role of the plastron in controlling fluid flow beyond the mere reduction in contact area and friction.

Viscous liquid flow in micro-channels is typically laminar because of the low Reynolds number constraint. However, by introducing elasticity into the fluids, the flow behavior could change drastically to become turbulent; this elasticity can be realized by dissolving small quantities of polymer molecules into an aqueous solvent. Our recent investigation has directly visualized the extension and relaxation of these polymer molecules in an aqueous solution. This elastic-driven phenomenon is known as ‘elastic turbulence’. Hitherto, existing studies on elastic flow instability are mostly limited to single-stream flows, and a comprehensive statistical analysis of a multi-stream elastic turbulent micro-channel flow is needed to provide additional physical understanding. Here, we investigate the flow field characteristics of elastic turbulence in a 3-stream contraction-expansion micro-channel flow. By applying statistical analyses and flow visualization tools, we show that the flow field bares many similarities to that of inertia-driven turbulence. More interestingly, we observed regions with two different types of power-law dependence in the velocity power spectra at high frequencies. This is a typical characteristic of two-dimensional turbulence and has hitherto not been reported for elastic turbulent micro-channel flows.

Fluid flows through nano-scale channels depend sensitively on the physical and chemical properties of the walls that surround them. The sub-micron dimensions of such channels, however, are impossible to resolve optically, which rules out most methods for flow visualization. Classic calculations by Squire (Q. J. Mech. Appl. Maths, vol. IV, 1951, pp. 321–329) and Landau & Lifshitz (Fluid Mechanics, vol. 6, 1959, Pergamon) showed that the laminar flow driven outside a capillary, by fluid emerging from the end of the capillary, is identical to the flow driven by a point force proportional to the average velocity in the capillary. Secchi et al. (J. Fluid Mech. 826, R3) analyze the dispersion of a solute that is injected along with the fluid, whose concentration decays slowly with distance but with a strong angular dependence that encodes the intra-capillary velocity. Fluorescence micrographs of the concentration profile emerging from the nanocapillary can be related directly to the average fluid velocity within the nanocapillary. Beyond their remarkable capacity for nano-velocimetry, Landau–Squire plumes will likely appear throughout micro- and nano-fluidic systems.

PurposeThe purpose of this paper is to discuss the 3D micropolar hybrid (Ag-CuO/H2O) nanofluid past rapid moving surface, where porous medium has been considered.Design/methodology/approachThe model of problem was represented by highly partial differential equations which were deduced by using suitable approximations (boundary layer). Then, the governing model was converted into five combined ordinary differential equations applying proper similarity transformations. Therefore, the eminent iterative Runge–Kutta–Fehlberg method (RKF45) has been applied to solve the resulting equations.FindingsHigher values of vortex viscosity, spin gradient viscosity and micro-inertia density parameters are reduced in horizontal direction, whereas opposite behaviour is noticed for vertical direction.Originality/valueThe work has not been done in the area of hybrid micropolar nanofluid. Hence, this article culminates to probe how to improve the thermal conduction and fluid flow in 3D boundary layer flow of micropolar mixture of nanoparticles driven by rapidly moving plate with convective boundary condition.

A constitutive model is proposed for simulations of hot forming processes. Dominant mechanisms in hot forming including inter-granular deformation, grain boundary sliding and grain boundary diffusion are considered in the constitutive model. A Taylor type polycrystalline model is used to predict inter-granular deformation. Previous works on grain boundary sliding and grain boundary diffusion are extended to drive three dimensional macro stress-strain rate relationships for each mechanism. In these relationships, the effect of grain size is also taken into account. It is shown that for grain boundary diffusion, stress-strain rate relationship obeys the Prandtl-Reuss flow rule. The proposed model is used to simulate step strain rate tests and the results are compared with experimental data. It is concluded that the model can be used to predict flow stress for various grain sizes and strain rates. The proposed model can be directly used in simulation of hot forming processes and as an example the bulge forming process is simulated and the results are compared with experimental data.

Advection by ocean currents modifies phytoplankton size structure at small scales (1–10 cm) by aggregating cells in different regions of the flow depending on their size. This effect is caused by the inertia of the cells relative to the displaced fluid. It is considered that, at larger scales (greater than or equal to 1 km), biological processes regulate the heterogeneity in size structure. Here, we provide observational evidence of heterogeneity in phytoplankton size structure driven by ocean currents at relatively large scales (1–10 km). Our results reveal changes in the phytoplankton size distribution associated with the coastal circulation patterns. A numerical model that incorporates the inertial properties of phytoplankton confirms the role of advection on the distribution of phytoplankton according to their size except in areas with enhanced nutrient inputs where phytoplankton dynamics is ruled by other processes. The observed preferential concentration mechanism has important ecological consequences that range from the phytoplankton level to the whole ecosystem.

This paper presents aspects of the concept and design of prostheses for the upper limb. The objective of this research is that of prototyping a customized prosthesis, with EMG signals that initiate the motion. The prosthesis’ fingers’ motions (as well as that of its hand and forearm parts) are driven by micro-motors, and assisted by the individualized command and control system. The software and hardware tandem concept of this mechatronic system enables complex motion (in the horizontal and vertical plane) with accurate trajectory and different set rules (gripping pressure, object temperature, acceleration towards the object). One important idea is regarding customization via reverse engineering techniques. Due to this, the dimensions and appearance (geometric characteristics) of the prosthesis would look like the human hand itself. The trajectories and motions of the fingers, thumbs, and joints have been studied by kinematic analysis with the matrix–vector method aided by Matlab. The concept and design of the mechanical parts allow for complex finger motion—rotational motion in two planes. The command and control system is embedded, and data received from the sensors are processed by a micro-controller for managing micro-motor control. Preliminary testing of the sensors and micro-motors on a small platform, Arduino, was performed. Prototyping of the mechanical components has been a challenge because of the high accuracy needed for the geometric precision of the parts. Several techniques of rapid prototyping were considered, but only DLP (digital light processing) proved to be the right one.

Cilia are micro-scale hair-like organelles. They can exhibit self-sustained oscillations which play crucial roles in flow transport or locomotion. Recent studies have shown that these oscillations can spontaneously emerge from dynamic instability triggered by internal stresses via a Hopf bifurcation. However, the flow transport induced by an instability-driven cilium still remains unclear, especially when the fluid is non-Newtonian. This study aims at bridging these gaps. Specifically, the cilium is modelled as an elastic filament, and its internal actuation is represented by a constant follower force imposed at its tip. Three generalized Newtonian behaviours are considered, i.e. the shear-thinning, Newtonian and shear-thickening behaviours. Effects of four key factors, including the filament zero-stress shape, Reynolds number ( $Re$ ), follower-force magnitude and fluid rheology, on the filament dynamics, fluid dynamics and flow transport are explored through direct numerical simulation at $Re$ of 0.04 to 5 and through a scaling analysis at $Re \approx 0$ . The results reveal that even though it is expected that inertia vanishes at $Re \ll 1$ , inertial forces do alter the filament dynamics and deteriorate the flow transport at $Re\ge 0.04$ . Regardless of $Re$ , the flow transport can be improved when the flow is shear thinning or when the follower force increases. Furthermore, a linear stability analysis is performed, and the variation of the filament beating frequency, which is closely correlated with the filament dynamics and flow transport, can be predicted.

Abstract The analytical solution for steady viscous pressure-driven compressible isothermal gas flow through micro- and nanochannels with variable cross section for all Knudsen and all Mach number values is presented in this paper. The continuum one-dimensional governing equations are solved using the friction factor that is established in a special way to provide solutions for mass flow rate, pressure, and velocity distribution through the microchannels and nanochannels in the entire rarefaction regime. The friction factor, defined by the general boundary condition and generalized diffusion coefficient proposed by Beskok and Karniadakis (1999, “A Model for Flows in Channels, Pipes, and Ducts at Micro and Nano Scales,” J. Microscale Thermophys. Eng., 3, pp. 43–77), spreads the solution application to all rarefaction regimes from continuum to free molecular flow. The correlation between the product of friction factor and Reynolds number (Poiseuille number) and Knudsen number is established explicitly in the paper. Moreover, the obtained solution includes the inertia effect, which allows the application of the solution to both subsonic and supersonic gas flows, which was not shown earlier. The presented solution confirms the existence of the Knudsen minimum in the diverging, converging, and microchannels and nanochannels with constant cross section. The proposed solution is verified by comparison with experimental, analytical, and numerical results available in literature.

Many fundamental biological processes are dependent on cellular migration. Although the mechanical mechanisms of single-cell migration are relatively well understood, those underlying migration of multiple cells adhered to each other in a cluster, referred to as cluster migration, are poorly understood. A key reason for this knowledge gap is that many forces—including contraction forces from actomyosin networks, hydrostatic pressure from the cytosol, frictional forces from the substrate, and forces from adjacent cells—contribute to cell cluster movement, making it challenging to model, and ultimately elucidate, the final result of these forces. This paper describes a two-dimensional cell membrane model that represents cells on a substrate with polygons and expresses various mechanical forces on the cell surface, keeping these forces balanced at all times by neglecting cell inertia. The model is discrete but equivalent to a continuous model if appropriate replacement rules for cell surface segments are chosen. When cells are given a polarity, expressed by a direction-dependent surface tension reflecting the location dependence of contraction and adhesion on a cell boundary, the cell surface begins to flow from front to rear as a result of force balance. This flow produces unidirectional cell movement, not only for a single cell but also for multiple cells in a cluster, with migration speeds that coincide with analytical results from a continuous model. Further, if the direction of cell polarity is tilted with respect to the cluster center, surface flow induces cell cluster rotation. The reason why this model moves while keeping force balance on cell surface (i.e., under no net forces from outside) is because of the implicit inflow and outflow of cell surface components through the inside of the cell. An analytical formula connecting cell migration speed and turnover rate of cell surface components is presented.

Setting the Mood Weirdly, everything feels the same. There’s absolutely no distinction for me between news, work, walking, gaming, Netflix, rock collecting, scrolling, messaging. I don’t know how this happened, but everything has simply blurred together. There’s a dreadful and yet soothing sameness to it, scrolling through images on Instagram, scrolling Netflix, walking the dog, scrolling the news, time scrolling by as I watch face after face appear or disappear on my screen, all saying something, yet saying nothing. Is this the rhythm of crisis in a slow apocalypse? Really, would it be possible for humans to just bore themselves into oblivion? Because in the middle of a pandemic, boredom feels in my body the same as doom ... just another swell that passes, like my chest as it rises and falls with my breath. This opening anecdote comes from combining narratives in two studies we conducted online during the COVID-19 pandemic in 2020: a global study, Massive and Microscopic Sensemaking: Autoethnographic Accounts of Lived Experience in Times of Global Trauma; and an Australian project, The Shut-In Worker: Working from Home and Digitally-Enabled Labour Practices. The Shut-In Worker project aimed to investigate the thoughts, beliefs, and experiences of Australian knowledge workers working from home during lockdown. From June to October 2020, we recruited twelve households across two Australian states. While the sample included households with diverse incomes and living arrangements—from metropolitan single person apartment dwellers to regional families in free standing households—the majority were relatively privileged. The households included in this study were predominantly Anglo-Australian and highly educated. Critically, unlike many during COVID-19, these householders had maintained their salaried work. Participating households took part in an initial interview via Zoom or Microsoft Teams during which they took us on workplace tours, showing us where and how the domestic had been requisitioned for salaried labour. Householders subsequently kept digital diaries of their working days ahead of follow up interviews in which we got them to reflect on their past few weeks working from home with reference to the textual and photographic diaries they had shared with us. In contrast to the tight geographic focus of The Shut-In Worker project and its fairly conventional methodology, the Massive and Microscopic Sensemaking project was envisaged as a global project and driven by an experimental participant-led approach. Involving more than 150 people from 26 countries during 2020, the project was grounded in autoethnography practice and critical pedagogy. Over 21 days, we offered self-guided prompts for ourselves and the other participants—a wide range of creative practitioners, scholar activists, and researchers—to explore their own lived experience. Participants with varying degrees of experience with qualitative methods and/or autoethnography started working with the research questions we had posed in our call; some independently, some in collaboration. The autoethnographic lens used in our study encouraged contributors to document their experience from and through their bodies, their situated daily routines, and their relations with embedded, embodied, and ubiquitous digital technologies. The lens enabled deep exploration and evocation of many of the complexities, profound paradoxes, fears, and hopes that characterise the human and machinic entanglements that bring us together and separate the planetary “us” in this moment (Markham et al. 2020). In this essay we draw on anecdotes and narratives from both studies that speak to the “Zoom experience” during COVID-19. That is, we use Zoom as a socio-technical pivot point to think about how the experience of liminality—of being on/off screen and ambiently in between—is operating to shift both our micro practices and macro structures as we experience and struggle within the rupture, “event”, and conjuncture that marks the global pandemic. What we will see is that many of those narratives depict disjointed, blurry, or confusing experiences, atmospheres, and affects. These liminal experiences are entangled in complex ways with the distinctive forms of commercial infrastructure and software that scaffold video conferencing platforms such as Zoom. Part of what is both enabling and troubling about the key proprietary platforms that increasingly host “public” participation and conversation online (and that came to play a dominant role during COVID19) in the context of what Tarleton Gillespie calls “the internet of platforms” is a sense of the hidden logics behind such platforms. The constant sense of potential dis/connection—with home computers becoming ambient portals to external others—also saw a wider experience of boundarylessness evoked by participants. Across our studies there was a sense of a complete breakdown between many pre-existing boundaries (or at least dotted lines) around work, school, play, leisure and fitness, public and media engagement, and home life. At the same time, the vocabulary of confinement and lockdown emerged from the imposition of physical boundaries or distancing between the self and others, between home and the outside world. During the “connected confinement” of COVID-19, study participants commonly expressed an affective sensation of dysphoria, with this new state of in betweenness or disorientation on and off screen, in and out of Zoom meetings, that characterises the COVID-19 experience seen by many as a temporary, unpleasant disruption to sociality as usual. Our contention is that, as disturbing as many of our experiences are and have been during lockdown, there is an important, ethically and politically generative dimension to our global experiences of liminality, and we should hold on to this state of de-normalisation. Much ink has been spilled on the generalised, global experience of videoconferencing during the COVID-19 pandemic. A line of argument within this commentary speaks to the mental challenge and exhaustion—or zoom fatigue as it is now popularly termed—that many have been experiencing in attempting to work, learn, and live collectively via interactive screen technologies. We suggest zoom fatigue stands in for a much larger set of global social challenges—a complex conjuncture of microscopic ruptures, decisions within many critical junctures or turning points, and slow shifts in how we see and make sense of the world around us. If culture is habit writ large, what should we make of the new habits we are building, or the revelations that our prior ways of being in the world might not suit our present planetary needs, and maybe never did? Thus, we counter the current dominant narrative that people, regions, and countries should move on, pivot, or do whatever else it takes to transition to a “new normal”. Instead, drawing on the work of Haraway and others interested in more than human, post-anthropocenic thinking about the future, this essay contends that—on a dying planet facing major global challenges—we need to be embracing liminality and “staying with the trouble” if we are to hope to work together to imagine and create better worlds. This is not necessarily an easy step but we explore liminality and the affective components of Zoom fatigue here to challenge the assumption that stability and certainty is what we now need as a global community. If the comfort experienced by a chosen few in pre-COVID-19 times was bought at the cost of many “others” (human and more than human), how can we use the discomfort of liminality to imagine global futures that have radically transformative possibilities? On Liminality Because liminality is deeply affective and experienced both individually and collectively, it is a difficult feeling or state to put into words, much less generalised terms. It marks the uncanny or unstable experience of existing between. Being in a liminal state is marked by a profound disruption of one’s sense of self, one’s phenomenological being in the world, and in relation to others. Zoom, in and of itself, provokes a liminal experience. As this participant says: Zoom is so disorienting. I mean this literally; in that I cannot find a solid orientation toward other people. What’s worse is that I realize everyone has a different view, so we can’t even be sure of what other people might be seeing on their screen. In a real room this would not be an issue at all. The concept of liminality originally came out of attempts to capture the sense of flux and transition, rather than stasis, that shapes culture and community, exemplified during rites of passage. First developed in the early twentieth century by ethnographer and folklorist Arnold van Gennep, it was later taken up and expanded upon by British anthropologist Victor Turner. Turner, best known for his work on cultural rituals and rites of passage, describes liminality as the sense of “in betweenness” experienced as one moves from one status (say that of a child) to another (formal recognition of adulthood). For Turner, community life and the formation of societies more broadly involves periods of transition, threshold moments in which both structures and anti-structures become apparent. Bringing liminality into the contemporary digital moment, Zizi Papacharissi discusses the concept in collective terms as pertaining to the affective states of networked publics, particularly visible in the development of new social and political formations through wide scale social media responses to the Arab Spring. Liminality in this context describes the “not yet”, a state of “pre-emergence” or “emergence” of unformed potentiality. In this usage, Papacharissi builds on Turner’s description of liminality as “a realm of pure possibility whence novel configurations of ideas and relations may arise” (97). The pandemic has sparked another moment of liminality. Here, we conceptualise liminality as a continuous dialectical process of being pushed and pulled in various directions, which does not necessarily resolve into a stable state or position. Shifting one’s entire lifeworld into and onto computer screens and the micro screens of Zoom, as experienced by many around the world, collapses the usual functioning norms that maintain some degree of distinction between the social, intimate, political, and work spheres of everyday life. But this shift also creates new boundaries and new rules of engagement. As a result, people in our studies often talked about experiencing competing realities about “where” they are, and/or a feeling of being tugged by contradictory or competing forces that, because they cannot be easily resolved, keep us in an unsettled, uncomfortable state of being in the world. Here the dysphoric experiences associated not just with digital liminality but with the broader COVID-19 epidemiological-socio-political conjuncture are illustrated by Sianne Ngai’s work on the politics of affect and “ugly feelings” in the context of capitalism’s relentlessly affirmative culture. Rather than dismissing the vague feelings of unease that, for many of us, go hand in hand with late modern life, Ngai suggests that such generalised and dispersed affective states are important markers of and guides to the big social and cultural problems of our time—the injustices, inequalities, and alienating effects of late capitalism. While critical attention tends to be paid to more powerful emotions such as anger and fear, Ngai argues that softer and more nebulous forms of negative affect—from envy and anxiety to paranoia—can tell us much about the structures, institutions, and practices that frame social action. These enabling and constraining processes occur at different and intersecting levels. At the micro level of the screen interface, jarring experiences can set us to wondering about where we are (on or off screen, in place and space), how we appear to others, and whether or not we should showcase and highlight our “presence”. We have been struck by how people in our studies expressed the sense of being handled or managed by the interfaces of Zoom or Microsoft Teams, which frame people in grid layouts, yet can shift and alter these frames in unanticipated ways. I hate Zoom. Everything about it. Sometimes I see a giant person, shoved to the front of the meeting in “speaker view” to appear larger than anyone else on the screen. People constantly appear and disappear, popping in and out. Sometimes, Zoom just rearranges people seemingly randomly. People commonly experience themselves or others being resized, frozen, or “glitched”, muted, accidentally unmuted, suddenly disconnected, or relegated to the second or third “page” of attendees. Those of us who attend many meetings as a part of work or education may enjoy the anonymity of appearing at a meeting without our faces or bodies, only appearing to others as a nearly blank square or circle, perhaps with a notation of our name and whether or not we are muted. Being on the third page of participants means we are out of sight, for better or worse. For some, being less visible is a choice, even a tactic. For others, it is not a choice, but based on lack of access to a fast or stable Internet connection. The experience and impact of these micro elements of presence within the digital moment differs, depending on where you appear to others in the interface, how much power you have over the shape or flow of the interaction or interface settings, or what your role is. Moving beyond the experience of the interface and turning to the middle range between micro and macro worlds, participants speak of attempting to manage blurred or completely collapsed boundaries between “here” and “there”. Being neither completely at work or school nor completely at home means finding new ways of negotiating the intimate and the formal, the domestic and the public. This delineation is for many not a matter of carving out specific times or spaces for each, but rather a process of shifting back and forth between makeshift boundaries that may be temporal or spatial, depending on various aspects of one’s situation. Many of us most likely could see the traces of this continuous shifting back and forth via what Susan Leigh Star called “boundary objects”. While she may not have intended this concept in such concrete terms, we could see these literally, in the often humorous but significantly disruptive introduction of various domestic actants during school or work, such as pets, children, partners, laundry baskets, beds, distinctive home decor, ambient noise, etc. Other trends highlight the difficulty of maintaining zones of work and school when these overlap with the rest of the physical household. One might place Post-it Notes on the kitchen wall saying “I’m in a Zoom meeting so don’t come into the living room” or blur one’s screen background to obscure one’s domestic location. These are all strategies of maintaining ontological security in an otherwise chaotic process of being both here and there, and neither here nor there. Yet even with these strategies, there is a constant dialectical liminality at play. In none of these examples do participants feel like they are either at home or at work; instead, they are constantly shifting in between, trying to balance, or straddling physical and virtual, public and private, in terms of social “roles” and “locations”. These negotiations highlight the “ongoingness” of and the labour involved in maintaining some semblance of balance within what is inherently an unbalanced dialectical process. Participants talked about and showed in their diaries and pictures developed for the research projects the ways they act through, work with, or sometimes just try to ignore these opposing states. The rise of home-based videoconferencing and associated boundary management practices have also highlighted what has been marginalised or forgotten and conversely, prioritised or valorised in prior sociotechnical assemblages that were simply taken for granted. Take for example the everyday practices of being in a work versus domestic lifeworld; deciding how to handle the labor of cleaning cups and dishes used by the “employees” and “students” in the family throughout the day, the tasks of enforcing school attendance by children attending classes in the family home etc. This increased consciousness—at both a household and more public level—of a previously often invisible and feminised care economy speaks to larger questions raised by the lockdown experience. At the same time as people in our studies were negotiating the glitches of screen presence and the weird boundarylessness of home-leisure-domestic-school-work life, many expressed an awareness of a troubling bigger picture. First, we had just the COVID lockdowns, you know, that time where many of us were seemingly “all together” in this, at home watching Tiger King, putting neighborly messages in our windows, or sharing sourdough recipes on social media. Then Black Lives Matters movements happened. Suddenly attention is shifted to the fact that we’re not all in this together. In Melbourne, people in social housing towers got abruptly locked down without even the chance to go to the store for food first, and yet somehow the wealthy or celebrity types are not under this heavy surveillance; they can just skip the mandatory quarantine. ... We can’t just go on with things as usual ... there are so many considerations now. Narratives like these suggest that while 2020 might have begun with the pandemic, the year raised multiple other issues. As many things have been destabilised, the nature or practice of everyday life is shifting under our feet. Around the world, people are learning how to remain more distanced from each other, and the rhythms of temporal and geographic movement are adapting to an era of the pandemic. Simultaneously, many people talk about an endlessly arriving (but never quite here) moment when things will be back to normal, implying not only that this feeling of uncertainty will fade, but also that the zone of comfort is in what was known and experienced previously, rather than in a state of something radically different. This sentiment is strong despite the general agreement that “we will never [be able to] go back to how it was, but [must] proceed to some ‘new normal’”. Still, as the participant above suggests, the pandemic has also offered a much broader challenge to wider, taken-for-granted social, political, and economic structures that underpin late capitalist nations in particular. The question then becomes: How do we imagine “moving on” from the pandemic, while learning from the disruptive yet critical moment it has offered us as a global community? Learning from Liminality I don’t want us to go back to “normal”, if that means we are just all commuting in our carbon spitting cars to work and back or traveling endlessly and without a care for the planet. COVID has made my life better. Not having to drive an hour each way to work every day—that’s a massive benefit. While it’s been a struggle, the tradeoff is spending more time with loved ones—it’s a better quality of life, we have to rethink the place of work. I can’t believe how much more I’ve been involved in huge discussions about politics and society and the planet. None of this would have been on my radar pre-COVID. What would it mean then to live with as well as learn from the reflexive sense of being and experience associated with the dis-comforts of living on and off screen, a Zoom liminality, if you will? These statements from participants speak precisely to the budding consciousness of new potential ways of being in a post-COVID-19 world. They come from a place of discomfort and represent dialectic tensions that perhaps should not be shrugged off or too easily resolved. Indeed, how might we consider this as the preferred state, rather than being simply a “rite of passage” that implies some pathway toward more stable identities and structured ways of being? The varied concepts of “becoming”, “not quite yet”, “boundary work”, or “staying with the trouble”, elaborated by Karen Barad, Andrew Pickering, Susan Leigh Star, and Donna Haraway respectively, all point to ways of being, acting, and thinking through and with liminality. All these thinkers are linked by their championing of murky and mangled conceptions of experience and more than human relations. Challenging notions of the bounded individual of rational humanism, these post-human scholars offer an often-uncomfortable picture of being in and through multiplicity, of modes of agency born out of a slippage between the one and the many. While, as we noted above, this experience of in betweenness and entanglement is often linked to emotions we perceive as negative, “ugly feelings”, for Barad et al., such liminal moments offer fundamentally productive and experimental modalities that enable possibilities for new configurations of being and doing the social in the anthropocene. Further, liminality as a concept potentially becomes radically progressive when it is seen as both critically appraising the constructed and conventional nature of prior patterns of living and offering a range of reflexive alternatives. People in our studies spoke of the pandemic moment as offering tantalizing glimpses of what kinder, more caring, and egalitarian futures might look like. At the same time, many were also surprised by (and skeptical of) the banality and randomness of the rise of commercial platforms like Zoom as a “choice” for being with others in this current lifeworld, emerging as it did as an ad hoc, quick solution that met the demands of the moment. Zoom fatigue then also suggests a discomfort about somehow being expected to fully incorporate proprietary platforms like Zoom and their algorithmic logics as a core way of living and being in the post-COVID-19 world. In this sense the fact that a specific platform has become a branded eponym for the experience of online public communicative fatigue is telling indeed. The unease around the centrality of video conferencing to everyday life during COVID-19 can in part be seen as a marker of anxieties about the growing role of decentralized, private platforms in “replacing or merging with public infrastructure, [thereby] creating new social effects” (Lee). Further, jokes and off-hand comments by study participants about their messy domestic interiors being publicized via social media or their boss monitoring when they are on and offline speak to larger concerns around surveillance and privacy in online spaces, particularly communicative environments where unregulated private platforms rather than public infrastructures are becoming the default norm. But just as people are both accepting of and troubled by a growing sense of inevitability about Zoom, we also saw them experimenting with a range of other ways of being with others, from online cocktail parties to experimenting with more playful and creative apps and platforms. What these participants have shown us is the need to “stay with the trouble” or remain in this liminal space as long as possible. While we do not have the space to discuss this possibility in this short provocation, Haraway sees this experimental mode of being as involving multiple actants, human and nonhuman, and as constituting important work in terms of speculating and figuring with various “what if” scenarios to generate new possible futures. As Haraway puts it, this process of speculative figuring is one of giving and receiving patterns, dropping threads, and so mostly failing but sometimes finding something that works, something consequential and maybe even beautiful, that wasn’t there before, of relaying connections that matter, of telling stories in hand upon hand, digit upon digit, attachment site upon attachment site, to craft conditions for flourishing in terran worlding. This struggle of course takes us far beyond decisions about Zoom, specifically. This deliberately troubling liminality is a process of recognizing old habits, building new ones, doing the hard work of reconsidering broader social formations in a future that promises more trouble. Governments, institutions, corporate entities, and even social movements like Transition Towns or #BuildBackBetter all seem to be calling for getting out of this liminal zone, whether this is to “bounce back” by returning to hyper-consumerist, wasteful, profit-driven modes of life or the opposite, to “bounce forward” to radically rethink globalization and build intensely localized personal and social formations. Perhaps a third alternative is to embrace this very transitional experience itself and consider whether life on a troubled, perhaps dying planet might require our discomfort, unease, and in-betweenness, including acknowledging and sometimes embracing “glitches” and failures (Nunes). Transitionality, or more broadly liminality, has the potential to enhance our understanding of who and what “we” are, or perhaps more crucially who “we” might become, by encompassing a kind of dialectic in relation to the experiences of others, both intimate and distant. As many critical commentators before us have suggested, this necessarily involves working in conjunction with a rich ecology of planetary agents from First People’s actors and knowledge systems--a range of social agents who already know what it is to be liminal to landscapes and other species--through and with the enabling affordances of digital technologies. This is an important, and exhausting, process of change. And perhaps this trouble is something to hang on to as long as possible, as it preoccupies us with wondering about what is happening in the lines between our faces, the lines of the technologies underpinning our interactions, the taken for granted structures on and off screen that have been visibilized. We are fatigued, not by the time we spend online, although there is that, too, but by the recognition that the world is changing. References Barad, Karen.

Introduction I am on the phone with a journalist discussing my research into anti-vaccination. As the conversation winds up, they ask a question I have come to expect: "how big do you think this is?" My answer is usually some version of the following: that we have no way of knowing. I and my fellow researchers can only see the information that is public or in the sunlight. How anti-vaccination information spreads through private networks is dark to us. It is private and necessarily so. This means that we cannot track how these conversations spread in the private or parochial spaces of Facebook, nor can we consider how they might extend into other modes of mediated communication. Modern communication is a complex and multiplatform accomplishment. Consider this: I am texting with my friend, I send her a selfie, in the same moment I hear a notification, she has DMed me a relevant Instagram post via that app. I move to Instagram and share another post in response; we continue our text message conversation there. Later in the day, I message her on Facebook Messenger while participating in a mutual WhatsApp group chat. The next day we Skype, and while we talk, we send links back and forth, which in hindsight are as clear as hieroglyphics before the Rosetta stone. I comment on her Twitter post, and we publicly converse back and forth briefly while other people like our posts. None of these instances are discrete conversational events, even though they occur on different platforms. They are iterations on the same themes, and the archival properties of social media and private messaging apps mean that neither of you forgets where you left off. The conversation slides not only between platforms and contexts but in and out of visibility. Digitally mediated conversation hums in the background of daily life (boring meetings, long commutes and bad dates) and expands our understanding of the temporal and sequential limits of conversation. In this article, I will explore digitally-mediated cross-platform conversation as a problem in two parts, and how we can understand it as part of the 'dark social'. Specifically, I want to draw attention to how 'dark' online spaces are part of our everyday communicative practices and are not necessarily synonymous with the illicit, illegal, or deviant. I argue that the private conversations we have online are also part of the dark social web, insofar as they are hidden from the public eye. When I think of dark social spaces, I think of what lies beneath the surface of murky waters, what hides behind in backstage areas, and the moments between platforms. In contrast, 'light' (or public) social spaces are often perceived as siloed. The boundaries between these platforms are artificially clean and do not appear to leak into other spaces. This article explores the dark and shadowed spaces of online conversation and considers how we might approach them as researchers. Conversations occur in the backchannels of social media platforms, in private messaging functions that are necessarily invisible to the researcher's gaze. These spaces are distinct from the social media activity analysed by Marwick and boyd. Their research examining teens' privacy strategies on social media highlights how social media posts that multiple audiences may view often hold encoded meanings. Social media posts are a distinct and separate category of activity from meditated conversations that occur one to one, or in smaller group chat settings. Second is the disjunction between social media platforms. Users spread their activity across any number of social media platforms, according to social and personal logics. However, these movements are difficult to capture; it is difficult to see in the dark. Platforms are not hermeneutically sealed off from each other, or the broader web. I argue that understanding how conversation moves between platforms and in the backstage spaces of platforms are two parts of the same dark social puzzle. Conversation Online Digital media have changed how we maintain our social connections across time and space. Social media environments offer new possibilities for communication and engagement as well as new avenues for control. Calls and texts can be ignored, and our phones are often used as shields. Busying ourselves with them can help us avoid unwanted face-to-face conversations. There are a number of critiques regarding the pressure of always-on contact, and a growing body of research that examines how users negotiate these demands. By examining group messaging, Mannell highlights how the boundaries of these chats are porous and flexible and mark a distinct communicative break from previous forms of mobile messaging, which were largely didactic. The advent of group chats has also led to an increasing complication of conversation boundaries. One group chat may have several strands of conversation sporadically re-engaged with over time. Manell's examination of group chats empirically illustrates the complexity of digitally-mediated conversations as they move across private, parochial, and public spaces in a way that is not necessarily temporally linear. Further research highlights the networked nature of digitally mediated interpersonal communication and how conversations sprawl across multiple platforms (Burchell). Couldry (16, 17) describes this complex web as the media manifold. This concept encompasses the networked platforms that comprise it and refers to its embeddedness in daily life. As we no longer “log on” to the internet to send and receive email, the manifold is both everywhere and nowhere; so too are our conversations. Gershon has described the ways we navigate the communicative affordances of these platforms as “media ideologies" which are the "beliefs, attitudes, and strategies about the media they [individuals] use" (391). Media ideologies also contain implicit assumptions about which platforms are best for delivering which kinds of messages. Similarly, Burchell argues that the relational ordering of available media technologies is "highly idiosyncratic" (418). Burchell contends that this idiosyncratic ordering is interdependent and relational, and that norms about what to do when are both assumed by individuals and learnt in their engagement with others (418). The influence of others allows us to adjust our practices, or as Burchell argues, "to attune and regulate one's own conduct … and facilitate engagement despite the diverse media practices of others" (418). In this model, individuals are constantly learning and renegotiating norms of conversation on a case by case, platform by platform basis. However, I argue that it is more illuminating to consider how we have collectively developed an implicit and unconscious set of norms and signals that govern our (collective) conduct, as digitally mediated conversation has become embedded in our daily lives. This is not to say that everyone has the same conversational skill level, but rather that we have developed a common toolbox for understanding the ebb and flow of digitally mediated conversations across platforms. However, these norms are implicit, and we only have a partial understanding of how they are socially achieved in digitally-mediated conversation. What Lies Beneath Most of what we do online is assumed not to be publicly visible. While companies like Facebook trace us across the web and peer into every nook and cranny of our private use patterns, researchers have remained focussed on what lies above in the light, not below, in the dark. This has meant an overwhelming focus on single platform studies that rely on the massification of data as a default measure for analysing sentiment and behaviour online. Sociologically, we know that what occurs in dark social spaces, or backstage, is just as important to social life as what happens in front of an audience (Goffman). Goffman's research uses the metaphor of the theatre to analyse how social life is accomplished as a performance. He highlights that (darkened) backstage spaces are those where we can relax, drop our front, and reveal parts of our (social) self that may be unpalatable to a broader audience. Simply, the public data accessible to researchers on social media are “trace data”, or “trace conversation”, from the places where conversations briefly leave (public) footprints and can be tracked and traced before vanishing again. Alternatively, we can visualise internet researchers as swabbing door handles for trace evidence, attempting to assemble a narrative out of a left-behind thread or a stray fingerprint. These public utterances, often scraped through API access, are only small parts of the richness of online conversation. Conversations weave across multiple platforms, yet single platforms are focussed on, bracketing off their leaky edges in favour of certainty. We know the social rules of platforms, but less about the rules between platforms, and in their darker spaces. Conversations briefly emerge into the light, only to disappear again. Without understanding how conversation is achieved and how it expands and contracts and weaves in and out of the present, we are only ever guessing about the social dynamics of mediated conversation as they shift between light, dark, and shadow spaces. Small things can cast large shadows; something that looms large may be deceptively small. Online they could be sociality distorted by disinformation campaigns or swarms of social bots. Capturing the Unseen: An Ethnomethodological Approach Not all data are measurable, computable, and controllable. There is uncertainty beyond what computational logics can achieve. Nooks and crannies of sociality exist beyond the purview of computable data. This suggests that we can apply pre-digital social research methods to capture these “below the surface” conversations and understand their logics. Sociologists have long understood that conversation is a social accomplishment. In the 1960s, sociologist Harvey Sacks developed conversation analysis as an ethnomethodological technique that seeks to understand how social life is accomplished in day-to-day conversation and micro-interactions. Conversation analysis is a detailed and systematic account of how naturally-occurring talk is socially ordered, and has been applied across a number of social contexts, including news interviews, judicial settings, suicide prevention hotlines, therapy sessions, as well as regular phone conversations (Kitzinger and Frith). Conversation analysis focusses on fine-grained detail, all of the little patterns of speech that make up a conversation; for example, the pauses, interruptions, self-corrections, false starts, and over-speaking. Often these too are hidden features of conversation, understood implicitly, but hovering on the edges of our social knowledge. One of the most interesting uses of conversational analysis is to understand refusal, that is, how we say 'no' as a social action. This body of research turns common-sense social knowledge – that saying no is socially difficult – into a systemic schema of social action. For instance, acceptance is easy to achieve; saying yes typically happens quickly and without hesitation. Acceptances are not qualified; a straightforward 'yes' is sufficient (Kitzinger and Frith). However, refusals are much more socially complex. Refusal is usually accomplished by apologies, compliments, and other palliative strategies that seek to cushion the blow of refusals. They are delayed and indirect conversational routes, indicating their status as a dispreferred social action, necessitating their accompaniment by excuses or explanations (Kitzinger and Frith). Research by Kitzinger and Frith, examining how women refuse sexual advances, illustrates that we all have a stock of common-sense knowledge about how refusals are typically achieved, which persists across various social contexts, including in our intimate relationships. Conversation analysis shows us how conversation is achieved and how we understand each other. To date, conversation analysis techniques have been applied to spoken conversation but not yet extended into text-based mediated conversation. I argue that we could apply insights from conversation analysis to understand the rules that govern digitally mediated conversation, how conversation moves in the spaces between platforms, and the rules that govern its emergence into public visibility. What rules shape the success of mediated communication? How can we understand it as a social achievement? When conversation analysis walks into the dark room it can be like turning on the light. How can we apply conversation analysis, usually concerned with the hidden aspects of plainly visible talk, to conversation in dark social spaces, across platforms and in private back channels? There is evidence that the norms of refusal, as highlighted by conversation analysis, are persistent across platforms, including in people's private digitally-mediated conversations. One of the ways in which we can identify these norms in action is by examining technology resistance. Relational communication via mobile device is pervasive (Hall and Baym). The concentration of digitally-mediated communication into smartphones means that conversational norms are constantly renegotiated, alongside expectations of relationship maintenance in voluntary social relationships like friendship (Hall and Baym). Mannell also explains that technology resistance can include lying by text message when explaining non-availability. These small, habitual, and often automatic lies are categorised as “butler lies” and are a polite way of achieving refusal in digitally mediated conversations that are analogous to how refusal is accomplished in face-to-face conversation. Refusals, rejections, and, by extension, unavailability appear to be accompanied by the palliative actions that help us achieve refusal in face-to-face conversation. Mannell identifies strategies such as “feeling ill” to explain non-availability without hurting others' feelings. Insights from conversation analysis suggest that on balance, it is likely that all parties involved in both the furnishing and acceptance of a butler lie understand that these are polite fabrications, much like the refusals in verbal conversation. Because of their invisibility, it is easy to assume that conversations in the dark social are chaotic and disorganised. However, there are tantalising hints that the reverse is true. Instead of arguing that individuals construct conversational norms on a case by case, platform by platform basis, I suggest that we now have a stock of common-sense social knowledge that we also apply to cross-platform mediated communication. In the spaces where gaps in this knowledge exist, Szabla and Blommaert argue that actors use existing norms of interactions and can navigate a range of interaction events even in online environments where we would expect to see a degree of context collapse and interactional disorganisation. Techniques of Detection How do we see in the dark? Some nascent research suggests a way forward that will help us understand the rhythms of cross-platform mediated conversation. Apps have been used to track participants' messaging and calling activities (Birnholtz, Davison, and Li). This research found a number of patterns that signal a user's attention or inattention, including response times and linguistic clues. Similarly, not-for-profit newsroom The Markup built a Facebook inspector called the citizen browser, a "standalone desktop application that was distributed to a panel of more than 1000 paid participants" (Mattu et al.). The application works by being connected to a participant's Facebook account and periodically capturing data from their Facebook feeds. The data is automatically deidentified but is still linked to the demographic information that participants provide about themselves, such as gender, race, location, and age. Applications like these point to how researchers might reliably collect interaction data from Facebook to glimpse into the hidden networks and interactions that drive conversation. User-focussed data collection methods also help us, as researchers, to sever our reliance on API access. API-reliant research is dependent on the largesse of social media companies for continued access and encourages research on the macro at the micro's expense. After all, social media and other digital platforms are partly constituted by the social acts of their users. Without speech acts that constitute mediated conversation, liking, sharing GIFs, and links, as well as the gaps and silences, digital platforms cease to exist. Digital platforms are not just archives of “big data”, but rather they are collections of speech and records of how our common-sense knowledge about how to communicate has stretched and expanded beyond face-to-face contexts. A Problem of Bots Ethnomethodological approaches have been critiqued as focussing too much on the small details of conversation, on nit-picking small details, and thus, as unable to comment on macro social issues of oppression and inequality (Kitzinger and Frith 311). However, understanding digitally-mediated conversation through the lens of talk-as-human-interaction may help us untangle our most pressing social problems across digital platforms. Extensive research examines platforms such as Twitter for “inauthentic” behaviour, primarily identifying which accounts are bots. Bots accounts are programmed Twitter accounts (for example) that automatically tweet information on political or contentious issues, while mimicking genuine engagement. Bots can reply to direct messages too; they converse with us as they are programmed to act as “humanly” as possible. Despite this, there are patterns of behaviour and engagement that distinguish programmed bot accounts, and a number of platforms are dedicated to their detection. However, bots are becoming increasingly sophisticated and better able to mimic “real” human engagement online. But there is as yet no systematic framework regarding what “real” digitally mediated conversation looks like. An ethnomethodological approach to understanding this would better equip platforms to understand inauthentic activity. As Yang and colleagues succinctly state, "a supervised machine learning tool is only as good as the data used for its training … even the most advanced [bot detection] algorithms will fail with outdated training datasets" (8). On the flipside, organisations are using chat bots to deliver cognitive behavioural therapy and assist people in moments of psychological distress. But the bots do not feel human; they reply instantly to any message sent. Some require responses in the form of emojis. The basis of therapy is talk. Understanding more accurately how naturally-occurring talk functions in online spaces could create more sensitive and genuinely therapeutic tools. Conclusion It is easy to forget that social media have largely mainstreamed over the last decade; in this decade, crucial social norms about how we converse online have developed. These norms allow us to navigate our conversations, with intimate friends and strangers alike across platforms, both in and out of public view, in ways that are often temporally non-sequential. Dark social spaces are a matter of intense marketing interest. Advertising firm Disruptive Advertising identified the very spaces that are the focus of this article as “dark social”: messaging apps, direct messaging, and native mobile apps facilitate user activity that is "not as easily controlled nor tracked". Dark social traffic continues to grow, yet our understanding of why, how, and for whom trails behind. To make sense of our social world, which is increasingly indistinguishable from online activity, we need to examine the spaces between and behind platforms, and how they co-mingle. Where are the spaces where the affordances of multiple platforms and technologies scrape against each other in uncomfortable ways? How do users achieve intelligible conversation not just because of affordances, but despite them? Focussing on micro-sociological encounters and conversations may also help us understand what could build a healthy online ecosystem. How are consensus and agreement achieved online? What are the persistent speech acts (or text acts) that signal when consensus is achieved? To begin where I started, to understand the scope and power of anti-vaccination sentiment, we need to understand how it is shared and discussed in dark social spaces, in messaging applications, and other backchannel spaces. Taking an ethnomethodological approach to these conversational interactions could also help us determine how misinformation is refused, accepted, and negotiated in mediated conversation. Focussing on “dark conversation” will help us more richly understand our social world and add much needed insight into some of our pressing social problems. References Burchell, Kenzie.

The habitual passenger cannot grasp the folly of traffic based overwhelmingly on transport. His inherited perceptions of space and time and of personal pace have been industrially deformed. He has lost the power to conceive of himself outside the passenger role (Illich 25).The most basic definition of Stillness refers to a state of being in the absence of both motion and disturbance. Some might say it is anti-American. Stillness denies the democratic freedom of mobility in a social system where, as Ivan Illich writes in Energy and Equity, people “believe that political power grows out of the capacity of a transportation system, and in its absence is the result of access to the television screen” (26). In America, it isn’t too far of a stretch to say that most are quite used to being interpolated as some sort of subject of the screen, be it the windshield or the flat screen. Whether in transport or tele-vision, life is full of traffic and flickering images. In the best of times there is a choice between being citizen-audience member or citizen-passenger. A full day might include both.But during the summer of 2008 things seemed to change. The citizen-passenger was left beached, not in some sandy paradise but in their backyard. In this state of SIMBY (stuck in my backyard), the citizen-passenger experienced the energy crisis first hand. Middle class suburbanites were forced to come to terms with a new disturbance due to rising fuel prices: unattainable motion. Domestic travel had been exchanged for domestication. The citizen-passenger was rendered what Paul Virilio might call, “a voyager without a voyage, this passenger without a passage, the ultimate stranger, and renegade to himself” (Crepuscular 131). The threat to capitalism posed by this unattainable motion was quickly thwarted by America’s 'big box' stores, hotel chains, and news networks. What might have become a culturally transformative politics of attainable stillness was hijacked instead by The Great American Staycation. The Staycation is a neologism that refers to the activity of making a vacation out of staying at home. But the Staycation is more than a passing phrase; it is a complex cultural phenomenon that targeted middle class homes during the summer of 2008. A major constraint to a happy Staycation was the uncomfortable fact that the middle class home was not really a desirable destination as it stood. The family home would have to undergo a series of changes, one being the initiation of a set of time management strategies; and the second, the adoption of new objects for consumption. Good Morning America first featured the Staycation as a helpful parenting strategy for what was expected to be a long and arduous summer. GMA defined the parameters of the Staycation with four golden rules in May of 2008:Schedule start and end dates. Otherwise, it runs the risk of feeling just like another string of nights in front of the tube. Take Staycation photos or videos, just as you would if you went away from home on your vacation. Declare a 'choratorium.' That means no chores! Don't make the bed, vacuum, clean out the closets, pull weeds, or nothing, Pack that time with activities. (Leamy)Not only did GMA continue with the theme throughout the summer but the other networks also weighed in. Expert knowledge was doled out and therapeutic interventions were made to make people feel better about staying at home. Online travel companies such as expedia.com and tripadvisor.com, estimated that 60% of regular vacation takers would be staying home. With the rise and fall of gas prices, came the rise of fall of the Staycation.The emergence of the Staycation occurred precisely at a time when American citizens were confronted with the reality that their mobility and localities, including their relationship to domestic space, were structurally bound to larger geopolitical forces. The Staycation was an invention deployed by various interlocutors most threatened by the political possibilities inherent in stillness. The family home was catapulted into the circuits of production, consumption, and exchange. Big TV and Big Box stores furthered individual’s unease towards having to stay at home by discursively constructing the gas prices as an impediment to a happy domestic life and an affront to the American born right to be mobile. What was reinforced was that Americans ideally should be moving, but could not. Yet, at the same time it was rather un-American not to travel. The Staycation was couched in a powerful rhetoric of one’s moral duty to the nation while playing off of middle class anxieties and senses of privilege regarding the right to be mobile and the freedom to consume. The Staycation satiates all of these tensions by insisting that the home can become a somewhere else. Between spring and autumn of 2008, lifestyle experts, representatives from major retailers, and avid Staycationers filled morning slots on ABC, NBC, FOX, CBS, and CNN with Staycation tips. CNN highlighted the Staycation as a “1st Issue” in their Weekend Report on 12 June 2008 (Alban). This lead story centred on a father in South Windsor, Connecticut “who took the money he would normally spend on vacations and created a permanent Staycation residence.” The palatial home was fitted with a basketball court, swimming pool, hot tub, gardening area, and volleyball court. In the same week (and for those without several acres) CBS’s Early Show featured the editor of behindthebuy.com, a company that specialises in informing the “time starved consumer” about new commodities. The lifestyle consultant previewed the newest and most necessary items “so you could get away without leaving home.” Key essentials included a “family-sized” tent replete with an air conditioning unit, a projector TV screen amenable to the outdoors, a high-end snow-cone maker, a small beer keg, a mini-golf kit, and a fast-setting swimming pool that attaches to any garden hose. The segment also extolled the virtues of the Staycation even when gas prices might not be so high, “you have this stuff forever, if you go on vacation all you have are the pictures.” Here, the value of the consumer products outweighs the value of erstwhile experiences that would have to be left to mere recollection.Throughout the summer ABC News’ homepage included links to specific products and profiled hotels, such as Hiltons and Holiday Inns, where families could at least get a few miles away from home (Leamy). USA Today, in an article about retailers and the Staycation, reported that Wal-Mart would be “rolling back prices on everything from mosquito repellent to portable DVD players to baked beans and barbecue sauce”. Target and Kohl’s were celebrated for offering discounts on patio furniture, grills, scented candles, air fresheners and other products to make middle class homes ‘staycationable’. A Lexis Nexis count revealed over 200 news stories in various North American sources, including the New York Times, Financial Times, Investors Guide, the Christian Science Monitor, and various local Consumer Credit Counselling Guides. Staying home was not necessarily an inexpensive option. USA Today reported brand new grills, grilling meats, patio furniture and other accoutrements were still going to cost six percent more than the previous year (24 May 2008). While it was suggested that the Staycation was a cost-saving option, it is clear Staycations were for the well-enough off and would likely cost more or as much as an actual vacation. To put this in context with US vacation policies and practices, a recent report by the Center for Economic and Policy Research called No-Vacation Nation found that the US is the only advanced economy in the world that does not guarantee its workers paid vacation (Ray and Schmidt 3). Subsequently, without government standards 25% of Americans have neither paid vacation nor paid holidays. The Staycation was not for the working poor who were having difficulty even getting to work in the first place, nor were they for the unemployed, recently job-less, or the foreclosed. No, the Staycationers were middle class suburbanites who had backyards and enough acreage for swimming pools and tents. These were people who were going to be ‘stuck’ at home for the first time and a new grill could make that palatable. The Staycation would be exciting enough to include in their vacation history repertoire.All of the families profiled on the major networks were white Americans and in most cases nuclear families. For them, unattainable motion is an affront to the privilege of their white middle class mobility which is usually easy and unencumbered, in comparison to raced mobilities. Doreen Massey’s theory of “power geometry” which argues that different people have differential and inequitable relationships to mobility is relevant here. The lack of racial representation in Staycation stories reinforces the reality that has already been well documented in the works of bell hooks in Black Looks: Race and Representation, Lynn Spigel in Welcome to the Dreamhouse: Popular Media and Postwar Suburbs, and Jeremy Packer in Mobility without Mayhem: Safety, Cars and Citizenship. All of these critical works suggest that taking easily to the great open road is not the experience of all Americans. Freedom of mobility is in fact a great American fiction.The proprietors for the Great American Staycation were finding all sorts of dark corners in the American psyche to extol the virtues of staying at home. The Staycation capitalised on latent xenophobic tendencies of the insular family. Encountering cultural difference along the way could become taxing and an impediment to the fully deserved relaxation that is the stuff of dream vacations. CNN.com ran an article soon after their Weekend Report mentioned above quoting a life coach who argued Staycations were more fitting for many Americans because the “strangeness of different cultures or languages, figuring out foreign currencies or worrying about lost luggage can take a toll” (12 June 2008). The Staycation sustains a culture of insularity, consumption, distraction, and fear, but in doing so serves the national economic interests quite well. Stay at home, shop, grill, watch TV and movies, these were the economic directives programmed by mass media and retail giants. As such it was a cultural phenomenon commensurable to the mundane everyday life of the suburbs.The popular version of the Staycation is a highly managed and purified event that reflects the resort style/compound tourism of ‘Club Meds’ and cruise ships. The Staycation as a new form of domestication bears a significant resemblance to the contemporary spatial formations that Marc Augé refers to as non-places – contemporary forms of homogeneous architecture that are scattered across disparate locales. The nuclear family home becomes another point of transfer in the global circulation of capital, information, and goods. The chain hotels and big box stores that are invested in the Staycation are touted as part of the local economy but instead devalue the local by making it harder for independent restaurants, grocers, farmers’ markets and bed and breakfasts to thrive. In this regard the Staycation excludes the local economy and the community. It includes backyards not balconies, hot-dogs not ‘other’ types of food, and Wal-Mart rather than then a local café or deli. Playing on the American democratic ideals of freedom of mobility and activating one’s identity as a consumer left little room to re-think how life in constant motion (moving capital, moving people, moving information, and moving goods) was partially responsible for the energy crisis in the first place. Instead, staying at home became a way for the American citizen to support the floundering economy while waiting for gas prices to go back down. And, one wouldn’t have to look that much further to see that the Staycation slips discursively into a renewed mission for a just cause – the environment. For example, ABC launched at the end of the summer a ruse of a national holiday, “National Stay at Home Week” with the tag line: “With gas prices so high, the economy taking a nosedive and global warming, it's just better to stay in and enjoy great ABC TV.” It comes as no shock that none of the major networks covered this as an environmental issue or an important moment for transformation. In fact, the air conditioning units in backyard tents attest to quite the opposite. Instead, the overwhelming sense was of a nation waiting at home for it all to be over. Soon real life would resume and everyone could get moving again. The economic slowdown and the energy crisis are examples of the breakdown and failure of capitalism. In a sense, a potential opened up in this breakdown for Stillness to become an alternative to life in constant and unrequited motion. That is, for the practice of non-movement and non-circulation to take on new political and cultural forms especially in the sprawling suburbs where the car moves individuals between the trifecta of home, box store, and work. The economic crisis is also a temporary stoppage of the flows. If the individual couldn’t move, global corporate capital would find a way to set the house in motion, to reinsert it back into the machinery that is now almost fully equated with freedom.The reinvention of the home into a campground or drive-in theatre makes the house a moving entity, an inverted mobile home that is both sedentary and in motion. Paul Virilio’s concept of “polar inertia” is important here. He argues, since the advent of transportation individuals live in a state of “resident polar inertia” wherein “people don’t move, even when they’re in a high speed train. They don’t move when they travel in their jet. They are residents in absolute motion” (Crepuscular 71). Lynn Spigel has written extensively about these dynamics, including the home as mobile home, in Make Room for TV and Welcome to the Dreamhouse. She examines how the introduction of the television into domestic space is worked through the tension between the private space of the home and the public world outside. Spigel refers to the dual emergence of portable television and mobile homes. Her work shows how domestic space is constantly imagined and longed for “as a vehicle of transport through which they (families) could imaginatively travel to an illicit place of passion while remaining in the safe space of the family home” (Welcome 60-61). But similarly to what Virilio has inferred Spigel points out that these mobile homes stayed parked and the portable TVs were often stationary as well. The Staycation exists as an addendum to what Spigel captures about the relationship between domestic space and the television set. It provides another example of advertisers’ attempts to play off the suburban tension between domestic space and the world “out there.” The Staycation exacerbates the role of the domestic space as a site of production, distribution, and consumption. The gendered dynamics of the Staycation include redecorating possibilities targeted at women and the backyard beer and grill culture aimed at men. In fact, ‘Mom’ might suffer the most during a Staycation, but that is another topic. The point is the whole family can get involved in a way that sustains the configurations of power but with an element of novelty.The Staycation is both a cultural phenomenon that feeds off the cultural anxieties of the middle class and an economic directive. It has been constructed to maintain movement at a time when the crisis of capital contains seeds for an alternative, for Stillness to become politically and culturally transformative. But life feels dull when the passenger is stuck and the virtues of Stillness are quite difficult to locate in this cultural context. As Illich argues, “the passenger who agrees to live in a world monopolised by transport becomes a harassed, overburdened consumer of distances whose shape and length he can no longer control” (45). When the passenger is the mode of identification, immobility becomes unbearable. In this context a form of “still mobility” such as the Staycation might be satisfying enough. ConclusionThe still citizen is a threatening figure for capital. In Politics of the Very Worst Virilio argues at the heart of capitalism is a state of permanent mobility, a condition to which polar inertia attests. The Staycation fits completely within this context of this form of mobile immobility. The flow needs to keep flowing. When people are stationary, still, and calm the market suffers. It has often been argued that the advertising industries construct dissatisfaction while also marginally eliminating it through the promises of various products, yet ultimately leaving the individual in a constant state of almost satisfied but never really. The fact that the Staycation is a mode of waiting attests to this complacent dissatisfaction.The subjective and experiential dimensions of living in a capitalist society are experienced through one’s relationship to time and staying on the right path. The economic slowdown and the energy crisis are also crises in pace, energy, and time. The mobility and tempo, the pace and path that capital relies on, has become unhinged and vulnerable to a resistant re-shaping. The Staycation re-sets the tempo of suburbia to meet the new needs of an economic slowdown and financial crisis. Following the directive to staycate is not necessarily a new form of false consciousness, but an intensified technological and economic mode of subjection that depends on already established cultural anxieties. But what makes the Staycation unique and worthy of consideration is that capitalists and other disciplinary institutions of power, in this case big media, construct new and innovative ways to control people’s time and regulate their movement in space. The Staycation is a particular re-territorialisation of the temporal and spatial dimensions of home, work, and leisure. In sum, Staycation and the staging of National Stay at Home Week reveals a systemic mobilising and control of a population’s pace and path. As Bernard Stiegler writes in Technics and Time: “Deceleration remains a figure of speed, just as immobility is a figure of movement” (133). These processes are inexorably tied to one another. Thinking back to the opening quote from Illich, we could ask how we might stop imagining ourselves as passengers – ushered along, falling in line, or complacently floating past. To be still in the flows could be a form of ultimate resistance. In fact, Stillness has the possibility of becoming an autonomous practice of refusal. It is after all this threatening potentiality that created the frenzied invention of the Staycation in the first place. To end where I began, Illich states that “the habitual passenger must adopt a new set of beliefs and expectations if he is to feel secure in the strange world” (25-26). The horizon of political possibility is uniformly limited for the passenger. Whether people actually did follow these directives during the summer of 2008 is hard to determine. The point is that the energy crisis and economic slowdown offered a potential to vacate capital’s premises, both its pace and path. But corporate capital is doing its best to make sure that people wait, staycate, and see it through. The Staycation is not just about staying at home for vacation. It is about staying within reach, being accounted for, at a time when departing global corporate capital seems to be the best option.

In the 1960s, especially in the West, art that was revelatory and art that was revealing operated at opposite ends of the aesthetic spectrum. On the side of the revelatory we can think of encounters synonymous with modernism, in which an expressionist painting was revelatory of the Freudian unconscious, or a Barnett Newman the revelatory intensity of the sublime. By contrast, the impulse to reveal in 1960s art was rooted in post-Duchampian practice, implicating artists as different as Lynda Benglis and Richard Hamilton, who mined the potential of an art that was without essence. If revelatory art underscored modernism’s transcendental conviction, critically revealing work tested its discursive rules and institutional conventions. Of course, nothing in history happens as neatly as this suggests, but what is clear is how polarized the language of artistic revelation was throughout the 1960s. With the international spread of minimalism, pop art, and fluxus, provisional reveals eventually dominated art-historical discourse. Aesthetic conviction, with its spiritual undertones, was haunted by its demystification. In the words of Donald Judd: “a work needs only to be interesting” (184).That art galleries could be sites of timely socio-political issues, rather than timeless intuitions undersigned by medium specificity, is one of the more familiar origin stories of postmodernism. Few artists symbolize this shift more than Hans Haacke, whose 2019 exhibition All Connected, at the New Museum, New York, examined the legacy of his outward-looking work. Born in Germany in 1936, and a New Yorker since 1965, Haacke has been linked to the term “institutional critique” since the mid 1980s, after Mel Ramsden’s coining in 1975, and the increased recognition of kindred spirits such as Mierle Laderman Ukeles, Michael Asher, Martha Rosler, Robert Smithson, Daniel Buren, and Marcel Broodthaers. These artists have featured in books and essays by the likes of Benjamin Buchloh, Hal Foster, and Yve-Alain Bois, but they are also known for their own contributions to art discourse, producing hybrid conceptions of the intellectual postmodern artist as historian, critic and curator.Haacke was initially fascinated by kinetic sculpture in the early 1960s, taking inspiration from op art, systems art, and machine-oriented research collectives such as Zero (Germany), Gruppo N (Italy) and GRAV (France, an acronym of Groupe de Recherche d’Art Visuel). Towards the end of the decade he started to produce more overtly socio-political work, creating what would become a classic piece from this period, Gallery-Goers’ Birthplace and Residence Profile, Part 1 (1969). Here, in a solo exhibition at New York’s Howard Wise Gallery, the artist invited viewers to mark their birthplaces and places of residence on a map. Questioning the statistical demography of the Gallery’s avant-garde attendees, the exhibition anticipated the meticulous sociological character of much of his practice to come, grounding New York art – the centre of the art world – in local, social, and economic fabrics.In the forward to the catalogue of All Connected, New Museum Director Lisa Philips claims that Haacke’s survey exhibition provided a chance to reflect on the artist’s prescience, especially given the flourishing of art activism over the last five or so years. Philips pressed the issue of why no other American art institution had mounted a retrospective of his work in three decades, since his previous survey, Unfinished Business, at the New Museum in 1986, at its former, and much smaller, Soho digs (8). It suggests that other institutions have deemed Haacke’s work too risky, generating too much political heat for them to handle. It’s a reputation the artist has cultivated since the Guggenheim Museum famously cancelled his 1971 exhibition after learning his intended work, Shapolsky et al. Manhattan Real Estate Holdings, A Real Time Social System as of May 1, 1971 (1971) involved research into dubious New York real estate dealings. Guggenheim director Thomas Messer defended the censorship at the time, going so far as to describe it as an “alien substance that had entered the art museum organism” (Haacke, Framing 138). Exposé was this substance Messer dare not name: art that was too revealing, too journalistic, too partisan, and too politically viscid. (Three years later, Haacke got his own back with Solomon R. Guggenheim Museum Board of Trustees, 1974, exposing then Guggenheim board members’ connections to the copper industry in Chile, where socialist president Salvador Allende had just been overthrown with US backing.) All Connected foregrounded these institutional reveals from time past, at a moment in 2019 when the moral accountability of the art institution was on the art world’s collective mind. The exhibition followed high-profile protests at New York’s Whitney Museum and Metropolitan Museum of Art, as well as at Sydney’s Museum of Contemporary Art, the Louvre, and the British Museum. These and other arts organisations have increasingly faced pressures, fostered by social media, to end ties with unethical donors, sponsors, and board members, with activist groups protesting institutional affiliations ranging from immigration detention centre management to opioid and teargas manufacturing. An awareness of the limits of individual agency and autonomy undoubtedly defines this era, with social media platforms intensifying the encumbrances of individual, group, and organisational identities. Hans Haacke, Gallery-Goers’ Birthplace and Residence Profile, Part 1, 1969 Hans Haacke, Gallery-Goers’ Birthplace and Residence Profile, Part 2, 1969-71Unfinished BusinessUnderscoring Haacke’s activist credentials, Philips describes him as “a model of how to live ethically and empathetically in the world today”, and as a beacon of light amidst the “extreme political and economic uncertainty” of the present, Trump-presidency-calamity moment (7). This was markedly different to how Haacke’s previous New York retrospective, Unfinished Business, was received, which bore the weight of being the artist’s first museum exhibition in New York following the Guggenheim controversy. In the catalogue to Haacke’s 1986 exhibition, then New Museum director Marcia Tucker introduced his work as a challenge, cautiously claiming that he poses “trenchant questions” and that the institution accepts “the difficulties and contradictions” inherent to any museum staging of his work (6).Philips’s and Tucker’s distinct perspectives on Haacke’s practice – one as heroically ethical, the other as a sobering critical challenge – exemplify broader shifts in the perception of institutional critique (the art of the socio-political reveal) over this thirty-year period. In the words of Pamela M. Lee, between 1986 and 2019 the art world has undergone a “seismic transformation”, becoming “a sphere of influence at once more rapacious, acquisitive, and overweening but arguably more democratizing and ecumenical with respect to new audiences and artists involved” (87). Haacke’s reputation over this period has taken a similar shift, from him being a controversial opponent of art’s autonomy (an erudite postmodern conceptualist) to a figurehead for moral integrity and cohesive artistic experimentation.As Rosalyn Deutsche pointed out in the catalogue to Haacke’s 1986 exhibition, a potential trap of such a retrospective is that, through biographical positioning, Haacke might be seen as an “exemplary political artist” (210). With this, the specific political issues motivating his work would be overshadowed by the perception of the “great artist” – someone who brings single-issue politics into the narrative of postmodern art, but at the expense of the issues themselves. This is exactly what Douglas Crimp discovered in Unfinished Business. In a 1987 reflection on the show, Crimp argued that, when compared with an AIDS-themed display, Homo Video, staged at the New Museum at the same time, reviewers of Haacke’s exhibition tended to analyse his politics “within the context of the individual artist’s body of work … . Political issues became secondary to the aesthetic strategies of the producer” (34). Crimp, whose activism would be at the forefront of his career in subsequent years, was surprised at how Homo Video and Unfinished Business spawned different readings. Whereas works in the former exhibition tended to be addressed in terms of the artists personal and partisan politics, Haacke’s prompted reflection on the aesthetics-politics juxtaposition itself. For Crimp, the fact that “there was no mediation between these two shows”, spoke volumes about the divisions between political and activist art at the time.New York Times critic Michael Brenson, reiterating a comment made by Fredric Jameson in the catalogue for Unfinished Business, describes the timeless appearance of Haacke’s work in 1986, which is “surprising for an artist whose work is in some way about ideology and history” (Brenson). The implication is that the artist gives a surprisingly long aesthetic afterlife to the politically specific – to ordinarily short shelf-life issues. In this mode of critical postmodernism in which we are unable to distinguish clearly between intervening in and merely reproducing the logic of the system, Haacke is seen as an astute director of an albeit ambiguous push and pull between political specificity and aesthetic irreducibility, political externality and the internalist mode of art about art. Jameson, while granting that Haacke’s work highlights the need to reinvent the role of the “ruling class” in the complex, globalised socio-economic situation of postmodernism, claims that it does so as representative of the “new intellectual problematic” of postmodernism. Haacke, according Jameson, stages postmodernism’s “crisis of ‘mapping’” whereby capitalism’s totalizing, systemic forms are “handled” (note that he avoids “critiqued” or “challenged”) by focusing on their manifestation through particular (“micro-public”) institutional means (49, 50).We can think of the above examples as constituting the postmodern version of Haacke, who frames very specific political issues on the one hand, and the limitless incorporative power of appropriative practice on the other. To say this another way, Haacke, circa 1986, points to specific sites of power struggle at the same time as revealing their generic absorption by an art-world system grown accustomed to its “duplicate anything” parameters. For all of his political intent, the artistic realm, totalised in accordance with the postmodern image, is ultimately where many thought his gestures remained. The philosopher turned art critic Arthur Danto, in a negative review of Haacke’s exhibition, portrayed institutional critique as part of an age-old business of purifying art, maintaining that Haacke’s “crude” and “heavy-handed” practice is blind to how art institutions have always relied on some form of critique in order for them to continue being respected “brokers of spirit”. This perception – of Haacke’s “external” critiques merely serving to “internally” strengthen existing art structures – was reiterated by Leo Steinberg. Supportively misconstruing the artist in the exhibition catalogue, Steinberg writes that Haacke’s “political message, by dint of dissonance, becomes grating and shrill – but shrill within the art context. And while its political effectiveness is probably minimal, its effect on Minimal art may well be profound” (15). Hans Haacke, MOMA Poll, 1970 All ConnectedSo, what do we make of the transformed reception of Haacke’s work since the late 1980s: from a postmodern ouroboros of “politicizing aesthetics and aestheticizing politics” to a revelatory exemplar of art’s moral power? At a period in the late 1980s when the culture wars were in full swing and yet activist groups remained on the margins of what would become a “mainstream” art world, Unfinished Business was, perhaps, blindingly relevant to its times. Unusually for a retrospective, it provided little historical distance for its subject, with Haacke becoming a victim of the era’s propensity to “compartmentalize the interpretive registers of inside and outside and the terms corresponding to such spatial­izing coordinates” (Lee 83).If commentary surrounding this 2019 retrospective is anything to go by, politics no longer performs such a parasitic, oppositional or even dialectical relation to art; no longer is the political regarded as a real-world intrusion into the formal, discerning, longue-durée field of aesthetics. The fact that protests inside the museum have become more visible and vociferous in recent years testifies to this shift. For Jason Farrago, in his review of All Connected for the New York Times, “the fact that no person and no artwork stands alone, that all of us are enmeshed in systems of economic and social power, is for anyone under 40 a statement of the obvious”. For Alyssa Battistoni, in Frieze magazine, “if institutional critique is a practice, it is hard to see where it is better embodied than in organizing a union, strike or boycott”.Some responders to All Connected, such as Ben Lewis, acknowledge how difficult it is to extract a single critical or political strategy from Haacke’s body of work; however, we can say that, in general, earlier postmodern questions concerning the aestheticisation of the socio-political reveal no longer dominates the reception of his practice. Today, rather than treating art and politics are two separate but related entities, like form is to content, better ideas circulate, such as those espoused by Bruno Latour and Jacques Rancière, for whom what counts as political is not determined by a specific program, medium or forum, but by the capacity of any actor-network to disrupt and change a normative social fabric. Compare Jameson’s claim that Haacke’s corporate and museological tropes are “dead forms” – through which “no subject-position speaks, not even in protest” (38) – with Battistoni’s, who, seeing Haacke’s activism as implicit, asks the reader: “how can we take the relationship between art and politics as seriously as Haacke has insisted we must?”Crimp’s concern that Unfinished Business perpetuated an image of the artist as distant from the “political stakes” of his work did not carry through to All Connected, whose respondents were less vexed about the relation between art and politics, with many noting its timeliness. The New Museum was, ironically, undergoing its own equity crisis in the months leading up to the exhibition, with newly unionised staff fighting with the Museum over workers’ salaries and healthcare even as it organised to build a new $89-million Rem Koolhaas-designed extension. Battistoni addressed these disputes at-length, claiming the protests “crystallize perfectly the changes that have shaped the world over the half-century of Haacke’s career, and especially over the 33 years since his last New Museum exhibition”. Of note is how little attention Battistoni pays to Haacke’s artistic methods when recounting his assumed solidarity with these disputes, suggesting that works such as Creating Consent (1981), Helmosboro Country (1990), and Standortkultur (Corporate Culture) (1997) – which pivot on art’s public image versus its corporate umbilical cord – do not convey some special aesthetico-political insight into a totalizing capitalist system. Instead, “he has simply been an astute and honest observer long enough to remind us that our current state of affairs has been in formation for decades”.Hans Haacke, News, 1969/2008 Hans Haacke, Wide White Flow, 1967/2008 Showing Systems Early on in the 1960s, Haacke was influenced by the American critic, artist, and curator Jack Burnham, who in a 1968 essay, “Systems Esthetics” for Artforum, inaugurated the loose conceptualist paradigm that would become known as “systems art”. Here, against Greenbergian formalism and what he saw as the “craft fetishism” of modernism, Burnham argues that “change emanates, not from things, but from the way things are done” (30). Burnham thought that emergent contemporary artists were intuitively aware of the importance of the systems approach: the significant artist in 1968 “strives to reduce the technical and psychical distance between his artistic output and the productive means of society”, and pays particular attention to relationships between organic and non-organic systems (31).As Michael Fried observed of minimalism in his now legendary 1967 essay Art and Objecthood, this shift in sixties art – signalled by the widespread interest in the systematic – entailed a turn towards the spatial, institutional, and societal contexts of receivership. For Burnham, art is not about “material entities” that beautify or modify the environment; rather, art exists “in relations between people and between people and the components of their environment” (31). At the forefront of his mind was land art, computer art, and research-driven conceptualist practice, which, against Fried, has “no contrived confines such as the theatre proscenium or picture frame” (32). In a 1969 lecture at the Guggenheim, Burnham confessed that his research concerned not just art as a distinct entity, but aesthetics in its broadest possible sense, declaring “as far as art is concerned, I’m not particularly interested in it. I believe that aesthetics exists in revelation” (Ragain).Working under the aegis of Burnham’s systems art, Haacke was shaken by the tumultuous and televised politics of late-1960s America – a time when, according to Joan Didion, a “demented and seductive vortical tension was building in the community” (41). Haacke cites Martin Luther King’s assassination as an “incident that made me understand that, in addition to what I had called physical and biological systems, there are also social systems and that art is an integral part of the universe of social systems” (Haacke, Conversation 222). Haacke created News (1969) in response to this awareness, comprising a (pre-Twitter) telex machine that endlessly spits out live news updates from wire services, piling up rolls and rolls of paper on the floor of the exhibition space over the course of its display. Echoing Burnham’s idea of the artist as a programmer whose job is to “prepare new codes and analyze data”, News nonetheless presents the museum as anything but immune from politics, and technological systems as anything but impersonal (32).This intensification of social responsibility in Haacke’s work sets him apart from other, arguably more reductive techno-scientific systems artists such as Sonia Sheridan and Les Levine. The gradual transformation of his ecological and quasi-scientific sculptural experiments from 1968 onwards could almost be seen as making a mockery of the anthropocentrism described in Fried’s 1967 critique. Here, Fried claims not only that the literalness of minimalist work amounts to an emphasis on shape and spatial presence over pictorial composition, but also, in this “theatricality of objecthood” literalness paradoxically mirrors (153). At times in Fried’s essay the minimalist art object reads as a mute form of sociality, the spatial presence filled by the conscious experience of looking – the theatrical relationship itself put on view. Fried thought that viewers of minimalism were presented with themselves in relation to the entire world as object, to which they were asked not to respond in an engaged formalist sense but (generically) to react. Pre-empting the rise of conceptual art and the sociological experiments of post-conceptualist practice, Fried, unapprovingly, argues that minimalist artists unleash an anthropomorphism that “must somehow confront the beholder” (154).Haacke, who admits he has “always been sympathetic to so-called Minimal art” (Haacke, A Conversation 26) embraced the human subject around the same time that Fried’s essay was published. While Fried would have viewed this move as further illustrating the minimalist tendency towards anthropomorphic confrontation, it would be more accurate to describe Haacke’s subsequent works as social-environmental barometers. Haacke began staging interactions which, however dry or administrative, framed the interplays of culture and nature, inside and outside, private and public spheres, expanding art’s definition by looking to the social circulation and economy that supported it.Haacke’s approach – which seems largely driven to show, to reveal – anticipates the viewer in a way that Fried would disapprove, for whom absorbed viewers, and the irreduction of gestalt to shape, are the by-products of assessments of aesthetic quality. For Donald Judd, the promotion of interest over conviction signalled scepticism about Clement Greenberg’s quality standards; it was a way of acknowledging the limitations of qualitative judgement, and, perhaps, of knowledge more generally. In this way, minimalism’s aesthetic relations are not framed so much as allowed to “go on and on” – the artists’ doubt about aesthetic value producing this ongoing temporal quality, which conviction supposedly lacks.In contrast to Unfinished Business, the placing of Haacke’s early sixties works adjacent to his later, more political works in All Connected revealed something other than the tensions between postmodern socio-political reveal and modernist-formalist revelation. The question of whether to intervene in an operating system – whether to let such a system go on and on – was raised throughout the exhibition, literally and metaphorically. To be faced with the interactions of physical, biological, and social systems (in Condensation Cube, 1963-67, and Wide White Flow, 1967/2008, but also in later works like MetroMobiltan, 1985) is to be faced with the question of change and one’s place in it. Framing systems in full swing, at their best, Haacke’s kinetic and environmental works suggest two things: 1. That the systems on display will be ongoing if their component parts aren’t altered; and 2. Any alteration will alter the system as a whole, in minor or significant ways. Applied to his practice more generally, what Haacke’s work hinges on is whether or not one perceives oneself as part of its systemic relations. To see oneself implicated is to see beyond the work’s literal forms and representations. Here, systemic imbrication equates to moral realisation: one’s capacity to alter the system as the question of what to do. Unlike the phenomenology-oriented minimalists, the viewer’s participation is not always assumed in Haacke’s work, who follows a more hermeneutic model. In fact, Haacke’s systems are often circular, highlighting participation as a conscious disruption of flow rather than an obligation that emanates from a particular work (148).This is a theatrical scenario as Fried describes it, but it is far from an abandonment of the issue of profound value. In fact, if we accept that Haacke’s work foregrounds intervention as a moral choice, it is closer to Fried’s own rallying cry for conviction in aesthetic judgement. As Rex Butler has argued, Fried’s advocacy of conviction over sceptical interest can be understood as dialectical in the Hegelian sense: conviction is the overcoming of scepticism, in a similar way that Geist, or spirit, for Hegel, is “the very split between subject and object, in which each makes the other possible” (Butler). What is advanced for Fried is the idea of “a scepticism that can be remarked only from the position of conviction and a conviction that can speak of itself only as this scepticism” (for instance, in his attempt to overcome his scepticism of literalist art on the basis of its scepticism). Strong and unequivocal feelings in Fried’s writing are informed by weak and indeterminate feeling, just as moral conviction in Haacke – the feeling that I, the viewer, should do something – emerges from an awareness that the system will continue to function fine without me. In other words, before being read as “a barometer of the changing and charged atmosphere of the public sphere” (Sutton 16), the impact of Haacke’s work depends upon an initial revelation. It is the realisation not just that one is embroiled in a series of “invisible but fundamental” relations greater than oneself, but that, in responding to seemingly sovereign social systems, the question of our involvement is a moral one, a claim for determination founded through an overcoming of the systemic (Fry 31).Haacke’s at once open and closed works suit the logic of our algorithmic age, where viewers have to shift constantly from a position of being targeted to one of finding for oneself. Peculiarly, when Haacke’s online digital polls in All Connected were hacked by activists (who randomized statistical responses in order to compel the Museum “to redress their continuing complacency in capitalism”) the culprits claimed they did it in sympathy with his work, not in spite of it: “we see our work as extending and conversing with Haacke’s, an artist and thinker who has been a source of inspiration to us both” (Hakim). This response – undermining done with veneration – is indicative of the complicated legacy of his work today. Haacke’s influence on artists such as Tania Bruguera, Sam Durant, Forensic Architecture, Laura Poitras, Carsten Höller, and Andrea Fraser has less to do with a particular political ideal than with his unique promotion of journalistic suspicion and moral revelation in forms of systems mapping. It suggests a coda be added to the sentiment of All Connected: all might not be revealed, but how we respond matters.
