Here where it lives … bioscleave

This essay introduces the work of Arakaw and Gins to interdisciplinary specialists and scholars and practitioners who are concerned with issues of art-science convergence. The co-authors discuss several points of view to the work of these artist-turned-architects and address the difficulties and challenges that their work represents in terms of the convergence and complexity of multiple dicourse and the practical challenges to embodied experience, technlogy-based approaches ot knowledge acquisition and perceptually-based learning environments.

Web 2.0 for networked learning : from collaboration to shared cognition and knowledge networking

This poster presents research-in-progress into the educational affordances of so-called Web 2.0 sites, services, with a particular emphasis on those applications that involve forms of shared human-machine cognition and that promote public knowledge networking. This research involves reviewing many hundreds of Web 2.0 tools and selecting approximately 50 for further analysis and exploration as learning applications. In doing so, the research will generate examples of unusual affordances provided by Web 2.0; it will also present a more structured categorisation of the kinds of uses and benefits of these tools. This approach is valuable because much current research and analysis of the impact of Web 2.0 on education, particularly higher education, has emphasised a relatively limited array of tools – principally blogs, wikis and social networking services – that offer educators and students opportunities for student-led collaborative work. Such opportunities involve strong emphasis on constructivist pedagogy: students’ interactions with each other, mediated via the Internet, are viewed as the positive benefit which networked learning can provide. However, Web 2.0 is far more than just collaboration, and associated shared self-expression. In particular, Web 2.0 includes many examples of services that take one form of input from a user and, rather than just sharing it with others, enable the transformation of that input into different forms, either as visualisations, maps, or other re-representations. Web 2.0 is also starting to see the development of knowledge-work engines that embody the concept of shared cognition, in which the service and the user cooperate in the production of some final knowledge output or which present to users knowledge that has already been processed more extensively than through simple searching. Web 2.0 is also closely associated with the idea that knowledge work is now networked and distributed; it involves users appropriating, creating and sharing knowledge products in a very public way, far beyond the narrow ‘audience’ of a particular course or program of study. The research presented in this poster will provide, firstly, examples of the Web 2.0 tools which emphasise these additional ways of exploiting the Internet for networked learning; secondly, the research will provide a first iteration of the overarching structure of categories and classifications which can be used to assess any proposed Web 2.0 application in terms of its affordances for learning as knowledge networking. By understanding these technologies, truly collaborative networked learning can be developed that blends with the emerging cultures of online behaviour increasingly common to contemporary student populations.

A slice sampler for restricted hierarchical beta process with applications to shared subspace learning

Hierarchical beta process has found interesting applications in recent years. In this paper we present a modified hierarchical beta process prior with applications to hierarchical modeling of multiple data sources. The novel use of the prior over a hierarchical factor model allows factors to be shared across different sources. We derive a slice sampler for this model, enabling tractable inference even when the likelihood and the prior over parameters are non-conjugate. This allows the application of the model in much wider contexts without restrictions. We present two different data generative models – a linear Gaussian-Gaussian model for real valued data and a linear Poisson-gamma model for count data. Encouraging transfer learning results are shown for two real world applications – text modeling and content based image retrieval.

Collaboration in 3D shared spaces using X3D and VRML

We propose a framework for visual and haptic collaboration in 3D shared virtual spaces. Virtual objects can de declared as shared objects which visual and physical properties are rendered synchronously on each client computer. We introduce virtual tools which are shared objects associated with interactive and haptic devices. We implement the proposed ideas as new pilot versions of BS Collaborate server and BS Contact VRML/X3D viewer. In our collaborative framework, two pipelines-visual and haptic-complement each other to provide a simple and efficient solution to problem requiring collaboration in shared virtual spaces on the Web. We discuss two implementation frameworks based on the strong and thin server concepts.

A framework for visual and haptic collaboration in shared virtual spaces

We propose a framework for visual and haptic collaboration in X3D/VRML shared virtual spaces. In this collaborative framework, two pipelines— visual and haptic—complement each other to provide a simple and efficient solution to problem requiring collaboration in shared virtual spaces on the web. We consider shared objects defined as virtual object with their visual and physical properties rendered synchronously on each client computer. We introduce virtual tools which are shared objects associated with interactive and haptic devices. We implemented the proposed ideas as a server-client framework with a dedicated viewer. We discuss two implementation frameworks based on the strong and thin server concepts.

Transforming history and myth: on the mutuality and separation of shared narratives in Eastern Tibet

Questioning the distinction between ‘cold’ and ‘hot’ societies, and an implied separation between myth and history, anthropologists have increasingly urged for an understanding of both myth and history as equally valid modes of shared social consciousness. This article takes up this point of view by referring to a written history of Lhagang, a town in Eastern Tibet; a history that appears to have the transformative content and oral circulation of myth. Using Lévi-Strauss’ structural analysis of myth and Santos-Granero's concept of topograms to demonstrate the mythemes that derive from the written history and circulate among Lhagang Tibetans, the article argues that, within the political and cultural context of Lhagang, myth and history shift in and out of indigenous categories even while being categorically distinct.

The shared role of oxidative stress and inflammation in major depressive disorder and nicotine dependence

Nicotine dependence is common in people with mood disorders; however the operative pathways are not well understood. This paper reviews the contribution of inflammation and oxidative stress pathways to the co-association of depressive disorder and nicotine dependence, including increased levels of pro-inflammatory cytokines, increased acute phase proteins, decreased levels of antioxidants and increased oxidative stress. These could be some of the potential pathophysiological mechanisms involved in neuroprogression. The shared inflammatory and oxidative stress pathways by which smoking may increase the risk for development of depressive disorders are in part mediated by increased levels of pro-inflammatory cytokines, diverse neurotransmitter systems, activation the hypothalamic-pituitary-adrenal (HPA) axis, microglial activation, increased production of oxidative stress and decreased levels of antioxidants. Depressive disorder and nicotine dependence are additionally linked imbalance between neuroprotective and neurodegenerative metabolites in the kynurenine pathway that contribute to neuroprogression. These pathways provide a mechanistic framework for understanding the interaction between nicotine dependence and depressive disorder.

Conversations through colour

The video exhibition and (performative lecture) shows and tell the story of the ways in which the changes in our shifting lives are sewn together by subtle yet persistent patterns such as our attraction to and preference for particular colours and colour combinations. The aim of the colour conversations is to focus on the sensory experience of color and elicit responses that might not emerge if an interview were to begin with the discussion of ideas or issues. In this way conversations take place in an expansive, shared field of experience from which personal and/or interpersonal observations can be made.

A Foucauldian and Deleuzian reading of autopoietic bisexual lives

This paper will locate the convergence of Foucault’s and ’Deleuze’s critico-political itinerary on the ethics of autopoiesis. It will re-evaluate the aims and objectives of Foucault’s ‘ethical turn’ in the later volumes of the history of sexuality project alongside Deleuzian ideas about the processes of becoming-other. Then, using primary research from a sociological study on bisexual lives, the paper will demonstrate the consonances of their respective theoretical insights about the potential of erotic ‘pleasure’ and ‘desire’ as a force of resistance. The aim of the analysis is twofold: firstly, to set the groundwork for further dialogical exchange between Deleuzian and Foucauldian thinking; and secondly, to highlight a lacuna in queer scholarship on bisexuality.
