A conjuntura de fragilidade que caracteriza a República da Guiné-Bissau aliada à pobreza do povo deste pequeno território da África Ocidental tem tido consequências catastróficas tanto na educação como no desenvolvimento do país. Cientes de que a educação constitui uma das chaves para a superação do subdesenvolvimento, o Governo guineense e a comunidade internacional têm reunido esforços, procurando inverter o cenário registado. O Estado português, sensível à situação do sistema educativo guineense, tem concentrado cerca de 50% do orçamento da ajuda destinada ao país, no âmbito da cooperação bilateral, à educação. Com este trabalho pretende-se analisar e compreender o impacto do projeto da cooperação portuguesa Programa de Apoio ao Sistema Educativo da Guiné-Bissau (PASEG), particularmente das Oficinas em Língua Portuguesa (OfLP), na promoção e difusão do português no país. Procura-se não só compreender se estes contribuíram para o desenvolvimento do sistema educativo guineense e para o uso do português nas escolas, como para a formação contínua de professores, a dinamização e requalificação das escolas, a implementação de uma abordagem do português como língua segunda e para uma aproximação dos jovens à língua oficial. A persecução dos objetivos da investigação resultará da aplicação de questionários e da recolha de testemunhos.

Economics is a social science which, therefore, focuses on people and on the decisions they make, be it in an individual context, or in group situations. It studies human choices, in face of needs to be fulfilled, and a limited amount of resources to fulfill them. For a long time, there was a convergence between the normative and positive views of human behavior, in that the ideal and predicted decisions of agents in economic models were entangled in one single concept. That is, it was assumed that the best that could be done in each situation was exactly the choice that would prevail. Or, at least, that the facts that economics needed to explain could be understood in the light of models in which individual agents act as if they are able to make ideal decisions. However, in the last decades, the complexity of the environment in which economic decisions are made and the limits on the ability of agents to deal with it have been recognized, and incorporated into models of decision making in what came to be known as the bounded rationality paradigm. This was triggered by the incapacity of the unboundedly rationality paradigm to explain observed phenomena and behavior. This thesis contributes to the literature in three different ways. Chapter 1 is a survey on bounded rationality, which gathers and organizes the contributions to the field since Simon (1955) first recognized the necessity to account for the limits on human rationality. The focus of the survey is on theoretical work rather than the experimental literature which presents evidence of actual behavior that differs from what classic rationality predicts. The general framework is as follows. Given a set of exogenous variables, the economic agent needs to choose an element from the choice set that is avail- able to him, in order to optimize the expected value of an objective function (assuming his preferences are representable by such a function). If this problem is too complex for the agent to deal with, one or more of its elements is simplified. Each bounded rationality theory is categorized according to the most relevant element it simplifes. Chapter 2 proposes a novel theory of bounded rationality. Much in the same fashion as Conlisk (1980) and Gabaix (2014), we assume that thinking is costly in the sense that agents have to pay a cost for performing mental operations. In our model, if they choose not to think, such cost is avoided, but they are left with a single alternative, labeled the default choice. We exemplify the idea with a very simple model of consumer choice and identify the concept of isofin curves, i.e., sets of default choices which generate the same utility net of thinking cost. Then, we apply the idea to a linear symmetric Cournot duopoly, in which the default choice can be interpreted as the most natural quantity to be produced in the market. We find that, as the thinking cost increases, the number of firms thinking in equilibrium decreases. More interestingly, for intermediate levels of thinking cost, an equilibrium in which one of the firms chooses the default quantity and the other best responds to it exists, generating asymmetric choices in a symmetric model. Our model is able to explain well-known regularities identified in the Cournot experimental literature, such as the adoption of different strategies by players (Huck et al. , 1999), the inter temporal rigidity of choices (Bosch-Dom enech & Vriend, 2003) and the dispersion of quantities in the context of di cult decision making (Bosch-Dom enech & Vriend, 2003). Chapter 3 applies a model of bounded rationality in a game-theoretic set- ting to the well-known turnout paradox in large elections, pivotal probabilities vanish very quickly and no one should vote, in sharp contrast with the ob- served high levels of turnout. Inspired by the concept of rhizomatic thinking, introduced by Bravo-Furtado & Côrte-Real (2009a), we assume that each per- son is self-delusional in the sense that, when making a decision, she believes that a fraction of the people who support the same party decides alike, even if no communication is established between them. This kind of belief simplifies the decision of the agent, as it reduces the number of players he believes to be playing against { it is thus a bounded rationality approach. Studying a two-party first-past-the-post election with a continuum of self-delusional agents, we show that the turnout rate is positive in all the possible equilibria, and that it can be as high as 100%. The game displays multiple equilibria, at least one of which entails a victory of the bigger party. The smaller one may also win, provided its relative size is not too small; more self-delusional voters in the minority party decreases this threshold size. Our model is able to explain some empirical facts, such as the possibility that a close election leads to low turnout (Geys, 2006), a lower margin of victory when turnout is higher (Geys, 2006) and high turnout rates favoring the minority (Bernhagen & Marsh, 1997).

RESUMÉ DE LA THÈSE EN FRANÇAIS La présente recherche se veut être un examen de la première enquête quantitative menée en Suisse sur les paroisses et communautés religieuses. La recherche vise de à appréhender la dynamique institutionnelle du champ religieux de ce pays. En relation avec une enquête similaire menée aux États-Unis (National Congregations Study, Chaves, 2004) la présente recherche analyse les données récoltées auprès d'un échantillon représentatif de plus de mille responsables spirituels des communautés religieuses de Suisse. Dans la perspective de la sociologie des organisations, elle examine le positionnement des communautés dans le champ institutionnel pour comprendre comment elles s'activent pour se maintenir dans la durée. Les communautés, pour assurer leurs services sur le long terme, sont imbriquées dans des structures confessionnelles avec des contraintes administratives diverses selon leur reconnaissance légale. En conséquence, la dynamique du champ religieux institutionnel est différenciée en trois environnements, selon leur degré de reconnaissance, qui demandent des réponses particulières à chacun pour pouvoir s'adapter et perdurer. Ces trois environnements poussent les groupes qui s'y logent à adopter des structures identiques. Pratiquer la religion ensemble, c'est ainsi se rendre dans une communauté avec une forme de rituel et d'engagement des membres correspondant à la reconnaissance du groupe par la société. Même pratiquée fortuitement, la religion collective est loin d'être un acte fortuit. RESUMÉ DE LA THÈSE EN ANGLAIS Practice the religion together Analysis of parishes and religious congregations in Switzerland in a perspective of sociology of organization This research is intended as a review of the first quantitative survey conducted in Switzerland on parishes and religious communities. The research aims to understand the dynamics of institutional religious field in this country. In connection with a similar survey conducted in the U.S. (National Congregations Study, Chaves, 2004) this research examines data gathered from a representative sample of over a thousand spiritual leaders of religious communities in Switzerland. From the perspective of sociology of organization, it examines the position of communities in the institutional field to understand how they are activated to maintain over time. Communities to ensure their services over the long term, are nested within denominational structures with different administrative constraints according to their legal recognition. Consequently, the dynamics of the religious field is differentiated into three institutional environments according to their degree of recognition, which require specific responses to each in order to adapt and endure. These three environments grow groups staying there to adopt identical structures.

Circulating levels of adiponectin, a hormone produced predominantly by adipocytes, are highly heritable and are inversely associated with type 2 diabetes mellitus (T2D) and other metabolic traits. We conducted a meta-analysis of genome-wide association studies in 39,883 individuals of European ancestry to identify genes associated with metabolic disease. We identified 8 novel loci associated with adiponectin levels and confirmed 2 previously reported loci (P = 4.5×10(-8)-1.2×10(-43)). Using a novel method to combine data across ethnicities (N = 4,232 African Americans, N = 1,776 Asians, and N = 29,347 Europeans), we identified two additional novel loci. Expression analyses of 436 human adipocyte samples revealed that mRNA levels of 18 genes at candidate regions were associated with adiponectin concentrations after accounting for multiple testing (p<3×10(-4)). We next developed a multi-SNP genotypic risk score to test the association of adiponectin decreasing risk alleles on metabolic traits and diseases using consortia-level meta-analytic data. This risk score was associated with increased risk of T2D (p = 4.3×10(-3), n = 22,044), increased triglycerides (p = 2.6×10(-14), n = 93,440), increased waist-to-hip ratio (p = 1.8×10(-5), n = 77,167), increased glucose two hours post oral glucose tolerance testing (p = 4.4×10(-3), n = 15,234), increased fasting insulin (p = 0.015, n = 48,238), but with lower in HDL-cholesterol concentrations (p = 4.5×10(-13), n = 96,748) and decreased BMI (p = 1.4×10(-4), n = 121,335). These findings identify novel genetic determinants of adiponectin levels, which, taken together, influence risk of T2D and markers of insulin resistance.

Ofrecer una visión sintética y pluridimensional del mundo universitario, con especial atención al estatuto del profesorado. Régimen jurídico de la Universidad española y, más concretamente, el relativo a su profesorado. El estudio se realiza en dos partes: en la primera se abordan cuestiones referentes a la Universidad española en general y en la segunda se analizan algunos aspectos del régimen jurídico del profesorado universitario. Boletín Oficial del Estado. Estatutos de la Universidad. Revistas. Código Civil. Constitución Española. Código Penal. Estatutos de Autonomía. Bibliografía. En el estudio general de la Universidad española se analiza: su origen, las funciones que desarrolla, los fines que persigue y las líneas rectoras de su regimen jurídico y económico; se analizan con especial detenimiento la autonomía universitaria, los estatutos de la Universidad y el carácter de Administración Pública que ostenta. Se abordan las cuestiones relativas al régimen jurídico del profesorado universitario, tanto funcionario como contratado. Se trata desde el régimen legal, las clases de profesorado y la plantilla docente, hasta todos los trámites seguidos en los procedimientos de selección, así como los derechos, deberes y obligaciones del profesorado universitario. Aborda también cuestiones tan polémicas como las relativas a la ordenación de los diversos cuerpos docentes, el alcance del concepto genérico de la libertad de cátedra, la adecuación de los criterios retributivos a las diversas categorías docentes, o el derecho que tiene un profesor a la asignación de una determinada docencia. Termina con una exposición de la protección jurisdiccional de los derechos del profesorado. La utilidad de esta obra se extiende a todo profesor universitario, que encontrará en ella la solución y/o el procedimiento a seguir en las dudas que le plantee su propia situación.

Este trabajo permite tener un acercamiento a la magnitud del problema que generan las sustancias químicas en los trabajadores de un municipio de Cundinamarca entre los años 1993-2008 basándose en los informes obtenidos de la unidad básica de la Dirección seccional Cundinamarca Regional Oriente del Instituto Nacional de Medicina Legal y Ciencias Forenses; hallando como principal causa de muerte la intoxicación por monóxido de carbono, en los trabajadores del sector informal. Genera además la inquietud de crear, un instrumento que permita un adecuado registro de estos eventos y a través de este, programas dirigidos a empleadores y trabajadores, que pueda concientizarlos de la exposición a la que se someten, ante un enemigo invisible como lo son las sustancias químicas y cuya consecuencia se observa claramente en la mortalidad de menores de edad que se encontraron durante la revisión de los informes

En los últimos seis años las relaciones del Líbano con Siria han estado marcadas por momentos de tensión política y militar específicamente a partir del 2005 cuando se dio un cambio en la geopolítica libanesa luego de dos sucesos relevantes como lo fueron la muerte del ex primer ministro Rafik Hariri y la retirada de las tropas sirias del Líbano. No obstante, es desde la guerra civil en 1975 que Siria toma un papel importante dentro del Líbano cuando interviene en este. Aunque esta intervención se transforma con el fin de la guerra, generando desequilibrio, interfiriendo en los asuntos internos, amenazando la soberanía, autonomía e integridad territorial libanesa.
