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.

The Political Economy of Climate Adaptation and Environmental Health: The Case of Ethiopia

The environment affects our health, livelihoods, and the social and political institutions within which we interact. Indeed, nearly a quarter of the global disease burden is attributed to environmental factors, and many of these factors are exacerbated by global climate change. Thus, the central research question of this dissertation is: How do people cope with and adapt to uncertainty, complexity, and change of environmental and health conditions? Specifically, I ask how institutional factors, risk aversion, and behaviors affect environmental health outcomes. I further assess the role of social capital in climate adaptation, and specifically compare individual and collective adaptation. I then analyze how policy develops accounting for both adaptation to the effects of climate and mitigation of climate-changing emissions. In order to empirically test the relationships between these variables at multiple levels, I combine multiple methods, including semi-structured interviews, surveys, and field experiments, along with health and water quality data. This dissertation uses the case of Ethiopia, Africa’s second-most populous nation, which has a large rural population and is considered very vulnerable to climate change. My fieldwork included interviews and institutional data collection at the national level, and a three-year study (2012-2014) of approximately 400 households in 20 villages in the Ethiopian Rift Valley. I evaluate the theoretical relationships between households, communities, and government in the process of adaptation to environmental stresses. Through my analyses, I demonstrate that water source choice varies by individual risk aversion and institutional context, which ultimately has implications for environmental health outcomes. I show that qualitative measures of trust predict cooperation in adaptation, consistent with social capital theory, but that measures of trust are negatively related with private adaptation by the individual. Finally, I describe how Ethiopia had some unique characteristics, significantly reinforced by international actors, that led to the development of an extensive climate policy, and yet with some challenges remaining for implementation. These results suggest a potential for adaptation through the interactions among individuals, communities, and government in the search for transformative processes when confronting environmental threats and climate change.

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.

The Distributional Effect of Events on Rural and Urban Households in China

International tourism is considered an effective means of economic development. However, the effects of tourism are not evenly distributed between rural and urban households in China. In the wake of significant socioeconomic events, the uneven distribution of the economic effects has huge welfare implications for Chinese households. This study is the first attempt to evaluate the distributional effect of two large, recent, sequential events on China's rural and urban households. It adopts an innovative approach that combines an econometric model and a two-household computable general equilibrium model. The results show that in terms of welfare, urban households were more adversely affected by the events than rural households. To mitigate the loss of welfare, measures should be taken to continually promote China as a destination and attract tourists after such events occur. Meanwhile, training and education should be made more accessible to rural households to increase their job opportunities.

Ecuadorian migration and family strategies of social mobility: dialectic relation between emotional and financial capital

This text deals with transnational strategies of social mobility in Ecuadorian migrant households in Spain. We apply the capital accumulation model (Moser, 2009) for this purpose. The main target of this article is, beyond thinking in terms of capital stock and accumulation, the analysis in depth of the dynamics of the different types of capital, that is to say, how they interact with each other in the framework of the social mobility strategies of the migrants and their families. We are bringing into light the way some households adopt investing decisions in capitals that don't translate into any addition or earnings in all cases, on the contrary, concentrating all their efforts on the accumulation of a certain asset they may, in some cases, lead to a loss of another. We will concentrate our analysis primarily on the dynamics between the physical and financial capital and the social and emotional capital, showing the tensions produced between these two types of assets. At the same time, we will highlight how migrants negotiate their family strategies of social mobility in the transnational area. Our study is based in empirical material obtained from qualitative fieldwork (in-depth interviews) with families of migrants in the urban district of Turubamba Bajo -(south of Quito) and in Madrid. A series of households were selected where interviews were carried out in the country of origin as well as in the context of immigration, with different family members, analysing the transnational social and economic strategies of families of migrant members. Family members of migrants established in Spain were interviewed in Quito, as well as key informants in the district (school teachers, nursery members of the staff, etc.). The research was framed within the projects "Impact of migration on the development: gender and transnationalism", Ministry of Science and Innovation (SEJ2007/63179) (Laura Oso, dir. 2007-2010),"Gender, transnationalism and intergenerational strategies of social mobility", Ministry of Economy and Competitiveness (FEM2011/26210) (Laura Oso, dir. 201-1-2015) and “Gender, Crossed Mobilities and Transnational Dynamics”, Ministry of Economy and Competitiveness (FEM2015-67164).

Financial literacy and over-indebtedness in low-income households

Financial literacy can explain a significant proportion of wealth inequality. Among the key components of financial literacy are numeracy and money management skills. Our study examines the relative importance of these components in the determination of consumer debt and household net worth among credit union members in socially disadvantaged areas. The main finding from our analysis is that money management skills are important determinants of financial outcomes but that numeracy has almost no role to play. This result adds to a recent US-based behavioural finance literature on the role of attention and planning in consumer finance. Findings are found to be robust when the sample is reduced to only those who have a clear role in household financial decision-making and also when controlling for potential endogeneity. Our findings have policy implications in the UK and elsewhere as credit unions across the world are important players in national financial literacy strategies.

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.
