We studied how the integration of seen and felt tactile stimulation modulates somatosensory processing, and investigated whether visuotactile integration depends on temporal contiguity of stimulation, and its coherence with a pre-existing body representation. During training, participants viewed a rubber hand or a rubber object that was tapped either synchronously with stimulation of their own hand, or in an uncorrelated fashion. In a subsequent test phase, somatosensory event-related potentials (ERPs) were recorded to tactile stimulation of the left or right hand, to assess how tactile processing was affected by previous visuotactile experience during training. An enhanced somatosensory N140 component was elicited after synchronous, compared with uncorrelated, visuotactile training, irrespective of whether participants viewed a rubber hand or rubber object. This early effect of visuotactile integration on somatosensory processing is interpreted as a candidate electrophysiological correlate of the rubber hand illusion that is determined by temporal contiguity, but not by pre-existing body representations. ERPmodulations were observed beyond 200msec post-stimulus, suggesting an attentional bias induced by visuotactile training. These late modulations were absent when the stimulation of a rubber hand and the participant’s own hand was uncorrelated during training, suggesting that pre-existing body representations may affect later stages of tactile processing.

In his 1967 essay, “Art and Objecthood”, Michael Fried bemoaned the theatricality of minimalist sculpture, which replaced the presentness of compositional sculpture with the staging of an experience for the viewer as performer. His argument has since been inverted by artists and art writers invested in the idea of sculptures as props forming part of an artistic experience economy. This discourse has accompanied the rise of relational aesthetics as a dominant paradigm for contemporary art. More recently, however, there has been a turn away from relationality to ‘object-oriented’ art, where objects are seen to stage their own theatrical experiences, performing themselves without requiring the activation of a viewer’s body. We trace parallels between the philosophy of Bruno Latour and the “Speculative Materialism” group and this emerging trend in sculpture. In ascribing agency to objects, Latour proposes a radical shift from philosophy’s traditional investigation of the relationship between the mind and the world. Drawn to the idea that matter can be creative, artists have embraced his thinking. However, we argue that this has lead to a generalized, universalizing humanism that disables political action. Moreover, it undermines the potential for anti-humanist critique latent in object-oriented philosophy.

Although the compact city is widely promoted as a sustainable form of urban development, little attention has been paid to the feasilibity of its implementation in practice. This paper addresses this isse by presenting the findings of a questionnaire study into the viability of the compact city from the perspective of the volume housebuilder. The study shows that, although well aware of the inherent problems witht the compact city, most were generally positive about the need to redirect more development back into urban areas. In addition, they suggested a large number of strategies for change, including i) a role for public sector agencies in overcoming the condstraints on urban sites; ii) the need for an upward reveision of acceptable densities in local plans and design guides; and iii) the creation of a separate, or revised, Use Class Order to enable mixed use development to compete on a level playing field. It is concluded that the residential developer could be engaged in the process of urban containment provided proposals for implementing the compact city of devised. The need for continuing research to test the actual effects of specific schemes is emphasised.

Surviving Objects (2012) is a devised multi-media practice-as-research performance based on extensive interviews conducted with my elderly mother and recorded on a hand-held device. Our conversations concern her experiences as a child refugee following violent deportation by the Soviet Army from Eastern Poland to Siberia (1941), and her subsequent route, via Persia, to a British-run refugee camp in Northern Rhodesia, where she remained for 6 years before arriving in the UK. In order to aid my mother’s reflections, our recorded conversations focus on the objects remaining from that period in her life – my ‘inheritance’. The material presence of this handful of objects is central to the ninety-minute performance. Surviving Objects constitutes my attempt to locate a theatrical form through which to root/re-route this engagement with my mother’s marginalised voice. The end-on performance haptically navigates themes of intimacy and failing memory – navigates, indeed, my constantly shifting relationship with my mother. It searches for new cross-medial pathways along which her experience, and my experience of her, can play-out. Surviving Objects involves: 1. live performance (two silent female actors handling/presenting my mother’s objects); 2. Film (two synchronously-playing, large-scale projections exploring the objects by means of a highly-magnifying macro lens); 3. Pre-recorded sound (my mother’s voice, taken from our recorded interviews, which were conducted in Polish, with my own verbal contribution meticulously editorially excised from those conversations); 4. My translation of her stories (appearing periodically as written text that ‘overlays’ - rather than sub- or surtitles - the projected imagery).

In this paper a generalization of collectively compact operator theory in Banach spaces is developed. A feature of the new theory is that the operators involved are no longer required to be compact in the norm topology. Instead it is required that the image of a bounded set under the operator family is sequentially compact in a weaker topology. As an application, the theory developed is used to establish solvability results for a class of systems of second kind integral equations on unbounded domains, this class including in particular systems of Wiener-Hopf integral equations with L1 convolutions kernels

In this project we explore how to enhance the experience and understanding of cultural heritage in museums and heritage sites by creating interactive multisensory objects collaboratively with artists, technologists and people with learning disabilities. We focus here on workshops conducted during the first year of a three year project in which people with learning disabilities each constructed a 'sensory box' to represent their experiences of Speke Hall, a heritage site in the UK. The box is developed further in later workshops which explore aspects of physicality and how to appeal to the entire range of senses, making use of Arduino technology and basic sensors to enable an interactive user experience.

In this paper we show how a seemingly unremarkable object – a cattle grid – has come to presence climate change in partial and contingent ways on the Lizard Peninsula, Cornwall, UK. We identify the cattle grid as an ‘anticipatory object’ through which conservation organisations seek to manage the future and adapt to climate change, but which at the same time presences that unthought-of future for others in the landscape. We explore the ways in which the cattle grid acts to presence something that is not only absent – climate change – but has uncertain imminence. We investigate the ways in which the cattle grid make climate relevant as an embodied and experiential process, a physical and intellectual artefact, and the means to imagine climate and the ways it might change. Drawing upon interpretative approaches informed by theorisations of materiality, presence and absence to understand climate change as a social phenomenon, we go beyond a consideration of this ordinary object defined by its function to consider how the object is experienced, the processes and practices through which people relate to it, and the ways in which social meaning accumulates around it. The empirical basis for this argument is provided by in-depth interviews with local representatives of Natural England, residents and farmers.

We present N-body simulations of accretion discs about young stellar objects (YSOs). The simulation includes the presence of a magnetic loop structure on the central star which interacts with the particles by means of a magnetic drag force. We find that an equilibrium spin rate is achieved when the corotation radius coincides with the edge of the loop. This spin rate is consistent with observed values for TTauri stars, being an order of magnitude less than the breakup value. The material ejected from the system by the rotating loop has properties consistent with the observed molecular outflows, given the presence of a suitable containing cavity.

Ice Age Art: Arrival of the Modern Mind was an exhibition at the British Museum from 27 February to 2 June 2013 exhibiting sculptures and engravings from the Ice Age of Europe and Eurasia, 40,000–10,000 years ago. It was accompanied by a lavishly illustrated book by Jill Cook with the same title, published by the British Museum Press. The exhibition was a sell-out, attracting considerable coverage in the press. Here I reflect critically on some aspects of the exhibition, exploring what such a display might tell us about ice age life, the modern mind and our present-day approach to displaying such objects.
