Factores individuais que condicionam a Saúde : um estudo caso-controlo

RESUMO - O presente projecto enquadra-se no paradigma salutogénico e visa apurar alguns dos factores que determinam que algumas pessoas se apresentem mais saudáveis que a população em geral. Foi seleccionado um estudo, quantitativo, analítico tipo caso-controlo (1 caso para 3 controlos), em que os casos são constituídos por indivíduos integrando a Função Pública que se encontram acima do percentil 95 de assiduidade ao trabalho nos últimos dois anos e com uma auto-percepção de Saúde classificada como muito boa, os controlos são indivíduos que não obedecem à definição de caso. Os indivíduos serão emparelhados por idade, género, estado civil, carreira, categoria profissional e unidade funcional que integram. A assiduidade será calculada com recurso aos certificados de incapacidade temporária entregues nos respectivos serviços. Os factores a estudar são os mais citados na literatura como factores salutogénicos ou factores de protecção, são eles: - Sentido de Coerência de Antonowsky - Locus de controlo - Auto conceito -Auto Eficácia - Aptidão física nas três vertentes clássicas: Capacidade aeróbia, Composição corporal, Aptidão muscular. Todos estes factores serão estudados com recurso a questionários auto preenchidos devidamente testados e validados para o português de Portugal sendo a aptidão física apurada com recurso á bateria de testes "Fitness Gram" adoptada para Portugal pelo Instituto do Desporto de Portugal e pelo Ministério da Educação. Os resultados serão apurados com recurso ao software de análise epidemiológica EPIDAT. 3.1. ---------------- ABSTRACT - The present project follows the salutogénic paradigm and intends to identify some of the factors that determine why some people are healthier than the general population. It was selected a quantitative, analytic, case-control study type (1 case to 3 controls), in which the cases are constituted by individuals who are integrated in Public Services and find themselves above 95 percentile of assiduity in work in the last two years, and with a self-perception of Health classified as very good, the controls are individuals who don’t obey to the case definition. The individuals will be matched by age, gender, civil state, career, professional category and Functional Unity in the Health services. The assiduity will be calculated with the help of temporary incapacity certificates delivered in the respective services. The currently studying factors are the most cited in literature, like salutogenic factors or protection factors, are those: - Antonowsky’s Sense of Coherence - Locus Control - Self-concept - Self-Efficacy - The three classic strands of Physical Fitness: Aerobic Capacity, Corporal Composition, Muscular Fitness. All these factors will be studied with the resource of properly tested and validated self-filled questionnaires for Portugal Portuguese (language), with the Physical Fitness being determined with the resource of “Fitness Gram” test battery, adopted for Portugal by the Portuguese Sports Institute and the Education Ministry. The results will be determined with the resource of the epidemiologic analysis software EPIDAT. 3.1.

Orientalism and Imperialism in French West Africa. Considerations on travel literature, colonial tourism, and the desert as a “commodity” in Mauritania

In this article we intend to make a summary overview of the influence that literary production, originated under colonial mapping missions or later in travel writing, had in the construction and establishment of a discourse to advertise and promote tourism in Mauritania. To this end we will draw on travel narratives that are illustrative of different periods and that correspond in some way to discourses of otherness. In this specific case, such discourses relate to the “Moors” of the West African coast and were produced in various historical contexts. We will also consider the discourse present in the tourism promotion materials of the colonial period and we will demonstrate to what extent it can be engaged in a dialogue with 19th and 20th centuries’ Western colonial literature.

Perspectives of Identity in Julio Cortázar’s Rayuela

My aim was to produce a dissertation, based on Rayuela, which focuses on Cortázar’s questioning of identity. With this objective in mind, I have studied some of the salient elements in the novel that relate to this topic and the subsequent, interrelated, areas of study that arose in doing so. The cities of Paris and Buenos Aires are placed in contrast within the novel and reflect a dichotomy that reflects Oliveira’s condition as a “foreigner,” (more specifically as a South American in Europe). This duality is further reflected in Cortázar’s use of gender, and the development of the notions of active and passive, and an investigation into the traditional modes of thought, symbols, and stereotypes, and an open-ended questioning of their validity. These topics are framed by a notion of Judeo-Christian History that is in many ways flawed and, as such, contrasts with a more intuitive (or “oriental”) perception of reality, which is centred in figures such as la Maga. I found many explicit references to Zen philosophy, and related oriental references, that led me to believe that this area was worthy of further investigation. Rayuela is considered a classic novel within the canon of Spanish language literature. It’s famous “tabla,” like the rules for a game between the writer and the receptor that produce alternative readings, has led to many discussions regarding the novel’s structure and form, and also created a certain amount of polemic with the use of concepts such as the “lector hembra.” Many consider Cortázar a greater short story writer than a novelist, but nevertheless this novel had a profound effect on young readers upon its publication, much to Cortázar’s surprise, and continues to attract readers, dealing as it does with issues that continue to be relevant to many people.

Essays on bounded rationality: Individual decision and strategic interaction

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).
