Arte y filosofía:Correlaciones entre el pensamiento estético de Jacques Rancière y Alain Badiou y el arte político de los colectivos artísticos Claire Fontaine, Raqs Media Collective y Estrella del Oriente

La presente tesis titulada Arte y Filosofía: Correlaciones entre el pensamiento estético de Jacques Rancière y Alain Badiou y el arte político de los colectivos artísticos Claire Fontaine, Raqs Media Collective y Estrella del Oriente, tiene como objetivo evidenciar y sostener, en la actualidad, un vínculo entre el arte y la filosofía, no mirando al arte como objeto de la filosofía, sino analizando las similitudes que se establecen cuando, tanto el arte como la filosofía, persiguen las mismas cosas. Para propiciar dicho vínculo nos amparamos en el pensamiento filosófico de Jacques Rancière y Alain Badiou, y en la práctica artística contemporánea de los siguientes colectivos: Claire Fontaine, Raqs Media Collective y Estrella del Oriente. En primer lugar hemos analizado y relacionado el pensamiento estético de ambos filósofos, indagando en lo han dicho sobre el arte y analizando también los conceptos claves y los cruces posibles entre sus teorías estéticas. Y en segundo lugar hemos pensado las prácticas del arte contemporáneo desde las ideas y ciertas categorías filosóficas presentes en ambos autores, sumando también las propias ideas que se desligan del pensamiento de los artistas y del análisis de sus obras. Consideramos que de esta forma hacemos un recorrido teórico en relación a lo que dicen los filósofos sobre el arte, lo que dicen los artistas sobre sus obras y lo que dicen las obras sobre el orden de las cosas...

Collective excitability, synchronization, and array-enhanced coherence resonance in a population of lasers with a saturable absorber

In this article we present a numerical study of the collective dynamics in a population of coupled semiconductor lasers with a saturable absorber, operating in the excitable regime under the action of additive noise. We demonstrate that temporal and intensity synchronization takes place in a broad region of the parameter space and for various array sizes. The synchronization is robust and occurs even for a set of nonidentical coupled lasers. The cooperative nature of the system results in a self-organization process which enhances the coherence of the single element of the population too and can have broad impact for detection purposes, for building all-optical simulators of neural networks and in the field of photonics-based computation.

Can the Quilombo Model of Collective Land Titling Work in Rio’s Favelas?

Due to their informality, the favelas of Rio de Janeiro are in a precarious position. Though the informal neighborhoods have long served as sites of affordable housing for Rio’s poorest residents, changes within in the city related to public security, mega-events, real estate speculation, and urban revitalization jeopardize their permanence. As one possible solution, this study, conducted for the client Catalytic Communities, investigated collective titling in favelas modeled after quilombos, territories recognized and titled by Brazilian federal law as patrimonies of black cultural traditions.

Role of Vinculin in Regulating Force-Sensitive Dynamics of Adherens Junctions During Collective Cell Migration

Dynamic processes such as morphogenesis and tissue patterning require the precise control of many cellular processes, especially cell migration. Historically, these processes are thought to be mediated by genetic and biochemical signaling pathways. However, recent advances have unraveled a previously unappreciated role of mechanical forces in regulating these homeostatic processes in of multicellular systems. In multicellular systems cells adhere to both deformable extracellular matrix (ECM) and other cells, which are sources of applied forces and means of mechanical support. Cells detect and respond to these mechanical signals through a poorly understood process called mechanotransduction, which can have profound effects on processes such as cell migration. These effects are largely mediated by the sub cellular structures that link cells to the ECM, called focal adhesions (FAs), or cells to other cells, termed adherens junctions (AJs).

Overall this thesis is comprised of my work on identifying a novel force dependent function of vinculin, a protein which resides in both FAs and AJs - in dynamic process of collective migration. Using a collective migration assay as a model for collective cell behavior and a fluorescence resonance energy transfer (FRET) based molecular tension sensor for vinculin I demonstrated a spatial gradient of tension across vinculin in the direction of migration. To define this novel force-dependent role of vinculin in collective migration I took advantage of previously established shRNA based vinculin knock down Marin-Darby Canine Kidney (MDCK) epithelial cells.

The first part of my thesis comprises of my work demonstrating the mechanosensitive role of vinculin at AJ’s in collectively migrating cells. Using vinculin knockdown cells and vinculin mutants, which specifically disrupt vinculin’s ability to bind actin (VinI997A) or disrupt its ability to localize to AJs without affecting its localization at FAs (VinY822F), I establish a role of force across vinculin in E-cadherin internalization and clipping. Furthermore by measuring E-cadherin dynamics using fluorescence recovery after bleaching (FRAP) analysis I show that vinculin inhibition affects the turnover of E-cadherin at AJs. Together these data reveal a novel mechanosensitive role of vinculin in E-cadherin internalization and turnover in a migrating cell layer, which is contrary to the previously identified role of vinculin in potentiating E-cadherin junctions in a static monolayer.

For the last part of my thesis I designed a novel tension sensor to probe tension across N-cadherin (NTS). N-cadherin plays a critical role in cardiomyocytes, vascular smooth muscle cells, neurons and neural crest cells. Similar to E-cadherin, N-cadherin is also believed to bear tension and play a role in mechanotransduction pathways. To identify the role of tension across N-cadherin I designed a novel FRET-based molecular tension sensor for N-cadherin. I tested the ability of NTS to sense molecular tension in vascular smooth muscle cells, cardiomyocytes and cancer cells. Finally in collaboration with the Horwitz lab we have been able to show a role of tension across N-cadherin in synaptogenesis of neurons.

Understandings of transnational families in debates on Migration and development

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

Non-Gaussian distribution of collective operators in quantum spin chains

We numerically analyse the behavior of the full distribution of collective observables in quantum spin chains. While most of previous studies of quantum critical phenomena are limited to the first moments, here we demonstrate how quantum fluctuations at criticality lead to highly non-Gaussian distributions. Interestingly, we show that the distributions for different system sizes collapse on thesame curve after scaling for a wide range of transitions: first and second order quantum transitions and transitions of the Berezinskii–Kosterlitz–Thouless type. We propose and analyse the feasibility of an experimental reconstruction of the distribution using light–matter interfaces for atoms in optical lattices or in optical resonators.

Permissibility of Non-Voluntary Collective Management of Copyright under EU Law – The Case of the French Law on Out-of-Commerce Books

The possibility of the EU member states to adapt copyright legislation to new circumstances and to address unforeseen issues is limited by the list of exceptions and restrictions of the InfoSoc Directive. In spite of this constraint, the EU copyright framework provides for a possibility of introduction of non-voluntary forms of collective rights management that can help to tackle some of the contemporary problems with remuneration and access. This article is an attempt to deepen the understanding of non-voluntary collective management and its possible use. First, it provides a detailed description of the French mechanism adopted for facilitating mass digitization and making out-of-commerce books available, which was implemented through a new form of collective management of copyright. Then, it examines the mechanism’s compatibility with the InfoSoc Directive through comparison with the extended collective licensing.

Exploring the Justificational Status of Assertions Made About Nursing’s Collective Beliefs

Nursing publications frequently reference groups (e.g. the group nurses). The nature and capabilities of group agents or collective subjects, and the relationship between nursing as a group and nurses as individuals is, however, rarely made explicit in these publications. Following Alvin Goldman, questions pertaining to groups can be classified as metaphysical or epistemic. Metaphysical questions take two forms. First, we might ask about the ontological status of group agents. For example, to what extent, if at all, do group agents exist and act independently of their constituent members? Second, we can ask whether group agents have psychological states or properties that can, for example, be formulated as propositional attitudes and, if they can, in what ways are group attitudes correlated with or tied to those of individual group members? In this presentation, having recognised the potential reality of group ontological and psychological being, I examine an under researched element of social epistemology. Specifically, the potential of non-individualist reliabilism (social process reliabilism) to justify doxastic group beliefs (i.e. statements such as “nurses believe that”) are considered. It is suggested that this issue has concrete implications for how we think about nursing.

“Art Will Not Disappear Into Nothing; It Will Disappear Into Everything“: The Black Audio Film Collective and Latin America

The development of Latin American cinema in the 1960s was underwritten by a number of key texts that outlined the aesthetic and political direction of individual filmmakers and collectives (Solanas and Getino, 1969; Rocha, 1965; Espinosa, 1969). Although asserting the specificity of Latin American culture, the theoretical foundations of its New Wave influenced oppositional filmmaking way beyond its own regional boundaries. This chapter looks at how movements in British art cinema, especially the Black Audio Film Collective, were inspired and propelled by the theories behind New Latin American cinema. Facilitated by English translations in journals such as Jump Cut in the early ‘80s, Cuban and Argentine cinematic manifestoes provided a radical alternative to the traditional language of film theory available to filmmakers in Europe and works such as Signs of Empire (1983-4); Handsworth Songs (1986) and Seven Songs for Malcolm X (1993) grew out of this trans-continental exchange. The Black Audio Film Collective represented a merging of politics, popular culture, and art that was, at once, oppositional and melodic. Fusing postcolonial discourse with pop music, the avant-garde and re-imaginings of subalternity, the work of ‘The Collective’ provides us with a useful example of how British art cinema has drawn from theoretical foundations formed outside of Europe and the West. As this chapter will argue however, the Black Audio Film Collective’s work can also be read as a reaction to the specificity of British socio-politics of the ‘80s and ‘90s. Its engagement with the aesthetico-political strategies of Latin American cinema, then, undercut what was a solidly British project, rooted in (post)colonial history and emerging ideas of disaporic identity. If the propulsive thrust of The Black Audio Film Collective’s art was shaped by Third Cinema, its images and concerns were self-consciously British.

A Computer Model of Drafting Effects on Collective Behavior in Elite 10,000 m Runners

Purpose Drafting in cycling influences collective behaviour of pelotons. Whilst evidence for collective behaviour in competitive running events exists, it is not clear if this results from energetic savings conferred by drafting. This study modelled the effects of drafting on behavior in elite 10,000 m runners. Methods Using performance data from a men’s elite 10,000 m track running event, computer simulations were constructed using Netlogo 5.1 to test the effects of three different drafting quantities on collective behaviour: no drafting, drafting to 3m behind with up to ~8% energy savings (a realistic running draft); and drafting up to 3m behind with up to 38% energy savings (a realistic cycling draft). Three measures of collective behaviour were analysed in each condition; mean speed, mean group stretch (distance between first and last placed runner), and Runner Convergence Ratio (RCR) which represents the degree of drafting benefit obtained by the follower in a pair of coupled runners. Results Mean speeds were 6.32±0.28m.s-1, 5.57±0.18 m.s-1, and 5.51±0.13 m.s-1 in the cycling draft, runner draft, and no draft conditions respectively (all P<0.001). RCR was lower in the cycling draft condition, but did not differ between the other two. Mean stretch did not differ between conditions. Conclusions Collective behaviours observed in running events cannot be fully explained through energetic savings conferred by realistic drafting benefits. They may therefore result from other, possibly psychological, processes. The benefits or otherwise of engaging in such behavior are, as yet, unclear.

Mandevillian Intelligence: From Individual Vice to Collective Virtue

Abstract Mandevillian intelligence is a specific form of collective intelligence in which individual cognitive vices (i.e., shortcomings, limitations, constraints and biases) are seen to play a positive functional role in yielding collective forms of cognitive success. In this talk, I will introduce the concept of mandevillian intelligence and review a number of strands of empirical research that help to shed light on the phenomenon. I will also attempt to highlight the value of the concept of mandevillian intelligence from a philosophical, scientific and engineering perspective. Inasmuch as we accept the notion of mandevillian intelligence, then it seems that the cognitive and epistemic value of a specific social or technological intervention will vary according to whether our attention is focused at the individual or collective level of analysis. This has a number of important implications for how we think about the cognitive impacts of a number of Web-based technologies (e.g., personalized search mechanisms). It also forces us to take seriously the idea that the exploitation (or even the accentuation!) of individual cognitive shortcomings could, in some situations, provide a productive route to collective forms of cognitive and epistemic success.
