The study aims to examine the influence of the prigogineane work on the formation of the new episteme behind all these changes, in the face of the paradigmatic rupture of the contemporary thought. The study will also understand the new knowledge body which these investigated changes are about to model along with the issues of contemporary world, like those regarding the science and philosophy, the boundaries of growth, sustainable development and the emergency of a new model of rationality. / É referência para este estudo a obra do físico-químico Ilya Prigogine, nucleada pelas idéias de complexidade e caos, que apontam para uma profunda transformação da ciência, originariamente desencadeada pela termodinâmica, seguida de perto pela teoria da relatividade e pela física quântica. O trabalho tem por meta examinar o alcance da obra prigogineana na conformação da nova episteme que subjaz a tais mudanças, em face da ruptura paradigmática que instaura o pensamento contemporâneo. De resto, importará ao estudo entrever o novo corpo de saber que as mudanças investigadas estão a modelar, em concurso com questões prementes do mundo contemporâneo, como as que dizem respeito à crise na ciência e na filosofia, aos limites do crescimento, ao desenvolvimento sustentável e à emergência de um novo modelo de racionalidade.

A RACIONALIDADE PEDAGÃGICA NO PROCESSO DE CORPORIFICAÃÃO DO CURRÃCULO QUE FORMA O PROFESSOR NA UNIVERSIDADE. / Pedagogic rationality in the process of corporation of the curriculum that forms the professor in the university

Adriana Campani 07 January 2008 (has links)
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Apresentamos, nesse estudo, uma reflexÃo sobre a racionalidade pedagÃgica que produz a formaÃÃo do professor na Universidade a partir de uma anÃlise sobre o processo de corporificarÃo dos currÃculos das licenciaturas no contexto de reforma curricular da Universidade Estadual Vale do AcaraÃ, situada em Sobral-CE. Analisamos os elementos constituÃdores dessa racionalidade a partir das formas de subjetivaÃÃo docente, produzidas pelo discurso pedagÃgico presente nas polÃticas de formaÃÃo do professor nas licenciaturas no Brasil e no processo de corporificaÃÃo dos currÃculos desses cursos no contexto de reforma curricular institucional. Defendemos a tese de que a racionalidade pedagÃgica produzida no processo de corporificarÃo dos currÃculos das licenciaturas na Universidade institui regras e modelos de ser e de conhecer do professor, à histÃrica, regionalizada e produzida no campo de luta e produÃÃo cultural; portanto, ela à uma epistemologia socialmente construÃda. Com base em nossos estudos teÃricos, compreendemos que o discurso pedagÃgico sobre a formaÃÃo do professor à uma prÃtica que envolve poder-saber e tÃcnicas de efeitos produtivos e prÃticos sobre os sujeitos e objetos. à um discurso que disputa formas de subjetividades e demarca diferenciaÃÃes, presenÃas, exclusÃes, saberes e verdades acerca do como pensar, ser e agir do docente. Identificamos esses âdispositivosâ no discurso oficial das Diretrizes Curriculares para formaÃÃo de professores, que estipula regras de poder que normatiza verdades sobre os professores e sua existÃncia e produzem formas de saberes que disputam modelos hegemÃnicos de subjetivaÃÃo docente, cujo poder de regulaÃÃo està no papel que o prÃprio docente passa a exercer quando sua competÃncia à vinculada a desenvolver formas inventivas para o seu prÃprio aprisionamento. No entanto, a anÃlise sobre a recontextualizaÃÃo desse discurso no contexto da prÃtica de reforma curricular identificou campos discursivos de novas relaÃÃes de saber-poder instituÃdas para resistir a essa regulaÃÃo. Constatamos que as decisÃes curriculares nas licenciaturas da UVA foram frutos de relaÃÃes conflituosas que disputaram territÃrio, identidade, autonomia e autoridade curricular com o conhecimento pedagÃgico na formaÃÃo do professor e a racionalidade pedagÃgica produzida no processo de reforma emergiu das condiÃÃes institucionais, a partir das quais houve interesse de mudanÃa, mas tambÃm de regulaÃÃo. AlÃm disso, entende-se que o conhecimento corporificado no currÃculo à tanto o resultado de relaÃÃes de poder quanto o constituidor das mesmas. A contribuiÃÃo dessa pesquisa à fornecer elementos para compreender que a racionalidade pedagÃgica que forma o professor na universidade se estrutura em um processo arenoso de disputa de subjetividade docente.

Sobre a dominação e a emancipação na teoria crítica de Herbert Marcuse / About domination and emancipation in critical theory by Herbert Marcuse

Stefan Fornos Klein 22 September 2006 (has links)
Esta dissertação apresenta quatro textos de Herbert Marcuse, inéditos na língua portuguesa. Para introduzi-los, desenvolvo uma exposição acerca do modo como o autor, em sua teoria crítica da sociedade, aborda as questões da dominação e da emancipação. Em uma breve introdução ao percurso intelectual de Marcuse, aponto as principais questões a permear o seu pensamento, com destaque para sua postura crítica face ao debate do marxismo como teoria social e como prática política, presente em toda a sua obra. No item seguinte, exponho a análise dos principais sentidos sociais e culturais que caracterizam o avanço da racionalidade e da civilização tecnológicas, fundamentais para compreender o diagnóstico de Marcuse sobre a lógica da dominação no capitalismo organizado. Em seguida, contextualizo, sucintamente, a institucionalização do ensino e da pesquisa acadêmicas nos Estados Unidos e os processos correlatos de especialização das disciplinas científicas e de profissionalização do trabalho intelectual. Por fim, trato da questão dos sujeitos da emancipação, na interpretação de Marcuse, face à prática política dos movimentos contraculturais que emergiram durante os anos 1960, indicando algumas tensões presentes em suas posições e enfatizando a importância da teoria para a transformação social, que se expressa em seu conceito de educação \"política\" ou \"crítica\". Após essa exposição segue, em ordem cronológica, a tradução dos textos de Marcuse: uma entrevista ao periódico Pardon, realizada em 1968; uma entrevista ao semanário Der Spiegel, de 1969; uma conversa acadêmica com Hans Magnus Enzensberger, de 1970; e uma palestra, realizada em Frankfurt, em 1979. Os textos abordam, centralmente, duas questões candentes do debate da esquerda da época: as possibilidades da revolta contra a civilização tecnológica e de sua transformação radical. / This dissertation presents four texts by Herbert Marcuse, not yet translated into the portuguese language. To introduce them, I develop an exposition concerning the way in which the author, in his critical theory of society, approaches the questions of domination and emancipation. In a brief introduction to Marcuse\'s intellectual course of life, I point out the central questions which permeate his thinking, punctuating his critical stand in face of the debate of Marxism as social theory and as political practice, present throughout his whole work. In the next item, I expose the analysis of the main social and cultural meanings which characterize the advancement of technological rationality and civilization, fundamental to understand Marcuse\'s diagnosis about the domination logic of organized capitalism. Afterwards I contextualize, succinctly, the institutionalization of academic teaching and research in the United States and the correlative processes of specialization of scientific disciplines and professionalization of intellectual work. At last, I deal with the question of the subjects of the emancipation, in Marcuse\'s interpretation, in face of the political practice of the countercultural movements which emerged during the 1960s, pointing out some existing tensions in his positions and emphasizing the importance of theory for social transformation, which his concept of \"political\" or \"critical\" education expresses. After this exposition follows, in chronological order, the translation of Marcuse\'s texts: an interview to the magazine Pardon, which took place in 1968; an interview to the weekly Der Spiegel, of 1969; an academic conversation with Hans Magnus Enzensberger, of 1970; and a speech, given in Frankfurt, in 1979. The texts approach, centrally, two blazing questions of the leftist debate of the time: the possibilities of the revolt against the technological civilization and its radical transformation.

Racionalidade jurídica e objetividade: a tese da resposta correta de Ronald Dworkin / Legal rationality and objectivity: Ronald Dworkin\'s right answer thesis

Igor Assagra Rodrigues Barbosa 17 October 2017 (has links)
Ao julgarem casos concretos, os juízes consultam e interpretam diversas fontes do direito com o intuito de determinar quais são os elementos jurídicos de decisão relevantes e como eles se aplicam a um determinado caso, apresentando os argumentos que fundamentam sua convicção e revelando uma respectiva racionalidade jurídica. No presente trabalho, pretendemos enfrentar o seguinte problema: pode o direito ser objetivo no sentido de que exista alguma racionalidade jurídica capaz de fornecer uma única resposta correta a um caso? Frente ao problema mais amplo da existência de respostas objetivamente corretas no direito, a pesquisa lança mão de um recorte autoral para estabelecer seu referencial. O interesse foi o de colaborar com o estudo do pensamento de Ronald Dworkin, o qual sustenta a tese de uma única resposta juridicamente correta. Para tanto, busca-se explorar os argumentos do autor a partir de um levantamento bibliográfico em materiais publicados em meios físicos e digitais. Após apontar alguns dos elementos da teoria positivista do direito de Hart que funcionaram como ponto de crítica inicial da perspectiva dworkiniana, divide-se a tese da resposta correta de Dworkin, que é objeto do trabalho, em duas etapas, tomando o texto Objectivity and truth: you\'d better believe it (1996) como marco de divisão. A primeira dessas etapas nos mostra que a tese da resposta correta no âmbito do direito fundamenta-se na concepção do autor acerca deste ser uma prática essencialmente interpretativa, orientada a identificar os valores que melhor justificam a história institucional e moral de uma comunidade. Logo, a resposta correta do ponto de vista jurídico depende da resposta correta do ponto de vista moral. Na segunda etapa, investiga-se a defesa de Dworkin frente aos diferentes ceticismos externos em relação à objetividade da moral, bem como suas ideias a respeito da independência metafísica do valor e a favor de uma epistemologia moral integrada. Ao final dos capítulos de cada etapa, noções críticas são apresentadas com o intuito de auxiliar na reflexão do pensamento do autor. / When judging concrete cases, judges consult and interpret several sources of law in order to determine what are the relevant legal elements of decision and how they apply to a certain case, presenting the arguments that support their conviction and revealing a respective legal rationality. In the present work, we intend to face the following issue: can the law be objective in the sense that there is a legal rationality capable of providing a single right answer to a particular case? Regarding the wider problem of the existence of objectively right answers in law, the research uses an authorial restriction in order to establish it\'s referential. The interest was to collaborate with the study of Ronald Dworkin\'s thought, which contains the one legal right answer thesis. To do so, we seek to explore the author\'s arguments from a bibliographical survey of published materials in print and digital media. After pointing out some of the elements of Hart\'s positivist theory of law that functioned as an initial point for the criticism of dworkinian\'s perspective, Dworkin\'s right answer thesis, that is its work\'s object, is divided in two phases, taking the text Objectivity and truth: you\'d better believe it (1996) as a division mark. The first of these phases shows us that the right answer thesis in legal scope is based on the author\'s conception about law being an essentially interpretative practice, oriented to identify the values that best justify the institutional and moral community history. Therefore, the right answer from a legal point of view depends on the right answer from the moral point of view. In the second phase, it investigates Dworkin\'s defense of different external skepticisms about moral objectivity, as well as his ideas about the metaphysical independence of the value and in favor of an integrated moral epistemology. At the end of each phase chapters, critical notions are introduced with the purpose of exercising the reflection about the author\'s presented thoughts.

A hermenêutica filosófica – como teoria do conhecimento pautada pela história – vem tentando se afirmar ao longo das últimas décadas como a que melhor daria conta desta leitura. Sendo as ciências um dos principais elementosconstituintes desta realidade moderna, se faz, portanto, necessária uma maior abertura do diálogo entre hermenêutica e epistemologia, já que, até então, a relação entre ambas tem se dado de maneira limitada e até mesmo problemática. A obra epistemológica de Bachelard emerge como possível suporte ao diálogo, na medida em que, em alguns de seus elementos, se apresenta de forma muito semelhante a vieses hermenêuticos, apesar de partirem de bases e interesses distintos. Logo, não se intenta aqui um simples enquadramento de parte do pensamento de Bachelard na tradição hermenêutica, mas sim, buscar um suporte nas categorias epistemológicas bachelardianas para a retomada efetiva ao diálogo com a hermenêutica, na busca por uma leitura consistente da realidade contemporânea. / This study aims to sustain the dialogue between the epistemology of the French philosopher Gaston Bachelard and some elements found in the hermeneutic tradition. The purpose of dialogue is born from the need for a reading key to better take account of the complex contemporary realities. The philosophical hermeneutics – as theory of knowledge guided by history – has been trying to assert themselves over the past decades as one that would be better this reading. Being the sciences one of the main constituents of this modern reality, it is therefore required a more open dialogue between hermeneutics and epistemology, since, until then, the relationship between them has been given limited and even problematically. The epistemological work of Bachelard emerges as a possible support of dialogue, to the extent that, in some of its elements, appears much like hermeneutic bias, although they left from different bases and interests. Soon, not attempts here a simple framing of the thought of Bachelard in hermeneutic tradition, but to seek a support in bachelardian as epistemological categories for the effective resumption of dialogue with hermeneutics, in the search for a consistent reading of contemporary reality.

Investor Rationality in Index Funds : An Analysis of the Swedish Investor Rationality when Investing in Index Funds

Sandberg, Adele, Ottosson, Frida January 2019 (has links)
iiABSTRACTBehavioral finance has been a popular research subject for a while and therefore the understanding of human behavior when it comes to private financial investments has increased. When comparing human behavior to the financial theories one can conclude thatthe assumption of perfect and efficient markets with fully informed and rational investors is not realistic. This study has therefore looked at the investor rationality when choosing which index fund to invest in. Index funds are to a large degree used asa savings tool for either pensions or other specific purposes. It was therefore interesting to look at the behavior of Swedish investors buyingthe Swedishindex funds available in Sweden with a quantitative analysis of the relationship between flow and other features of index funds. The dependent variable reflecting rationality was the fund flow and the independent variables were return, tracking error, size, fee and risk. No previous studies have been made on the investor rationality regarding index funds in the Swedish market, although similar studies havebeen done on the American S&P 500 investors. 17 index funds were included in this study, which is the whole population of index funds following Swedish indices available in Sweden at the point of time when this study was conducted. From this population funds that had been available for more than 3 years was chosen since we wanted to look at the behavior based on a longer time span than one year. In the end, 17index funds with 51observations was included in the study.Five hypotheses were created and tested of whichtwowereaccepted. From the regression model we found that return and standard deviation (SD) weresignificant andhadpositiverelationshipswith the fund flow. This implies that Swedish investors are rational to some degree but not fully rational since they are not taking any of the other variables into account which a rational investor ought to consider. It is therefore useful information for both investors and fund companies to see which factors weight in the most and how rational the behavior is. Conclusions from this study is that Swedish investors are subject to the index fund rationality paradox to some degree and the rational choice theory applies to some extent. One has to fully consider the outcomes of an action and base the decisionon utility maximization that the outcome will give one. To act fully rational is hard even for the most aware investor and even harder for an ordinary investor with gaps in knowledge and limited resources to information.

Financial advice and consumer protection / Conseil financier et protection des consommateurs

Kim, Areum 02 October 2014 (has links)
Cette thèse porte sur le régime de protection des consommateurs qui vise à prévenir les ventes abusives dans les services de conseil en investissement. Elle examine les conflits d'intérêts dus au comportement des conseillers financiers qui peuvent entraîner des ventes abusives. Le fait que la rationalité du consommateur puisse être limitée signifie que les consommateurs financiers traditionnellement considérés comme des clients de détail ou des investisseurs de détail sont en effet exposés au risque de conflits d'intérêts dans le processus de conseil en investissement et nécessitent donc une protection accrue. La directive MIF a récemment renforcé son dispositif afin de protéger plus efficacement les consommateurs contre le problème persistant des ventes abusives. La modification de la réglementation de la protection des consommateurs est significative en ce qu'elle renforce le régime général de protection des consommateurs de la directive MIF en mettant l'accent sur la vulnérabilité réelle des consommateurs. Elle contribue en outre à la promotion du système de protection du consommateur en imposant des devoirs de comportement aux sociétés financières qui doivent gérer des conflits d'intérêts spécifiques dans le cadre du grand principe de la protection des consommateurs. Cependant, même si l’intention à l’origine de son introduction est largement reconnue, la mise en place et la mise en œuvre pratiques de certains règlements devraient rencontrer des difficultés et donc nécessiter que des mesures supplémentaires soient prises. / The thesis deals with the consumer protection scheme which aims to prevent mis-selling in investment advice services. It examines the conflicts of interest which appear in the behavior of investment advisors which may ultimately cause mis-selling scandals. The research findings of behavioral economics that the consumer’s rationality can be bounded indicate that financial consumers who are traditionally considered as retail clients or retail investors are indeed vulnerable to the risk of conflicts of interest in investment advisory processes and thus need enhanced consumer protection. MiFID I has recently strengthened its scheme with a view to protecting consumers more effectively from persistent problems of mis-selling. The amendment of the consumer protection regulation is meaningful in that it strengthens the overall consumer protection scheme within the MiFID with a focus on the actual vulnerability of consumers. Furthermore, it contributes to the fostering of the consumer protection system by imposing behavioral duties on financial firms which manage specific conflicts of interest under the important principle of consumer protection. However, even though the intention at the origin of its introduction is widely recognized, it is expected that some difficulties will arise when some of the regulations are virtually introduced and implemented, and thus supplementary measures will have to be established.

Pierre Guariche designer-architecte d'intérieur (1926-1995) et les nouveaux programmes architecturaux issus de la croissance / Pierre Guariche interior architect-designer (1926-1995) and the new architectural programs stemming from the economic growth

Jacob, Delphine 27 March 2015 (has links)
Cette thèse propose une approche monographique du parcours professionnel de Pierre Guariche, décorateur-créateur d’ensembles-Architecte d'intérieur français. Les «Trente Glorieuses» représentent un tournant décisif chez ce professionnel car elles coïncident avec les débuts de l'industrialisation de la filière ameublement. Le contexte historique et politique explique son engagement dans la création de programmes complets d'objets destinés il meuble les logements standardisés de la Reconstruction. Il comprend que le mobilier de série, fabriqué par des procédés industriels et a des prix raisonnables. peut remédier aux effets de l'insuffisance de la politique de l'Etat français. Afin d'adapter son mobilier «moderne» au plan-type. il s'inspire dl' la production des designers américains et crée des objets rationnels normalisés et innovants sur le plan technique et esthétique. En 1954, il sollicite Michel Mortier et Joseph-André Motte, et crée avec eux l' Atelier de Recherches Plastiques. Ils comprennent tous les trois que les jeunes créateurs doivent se fédérer autour d'un projet commun: la promotion de leurs meubles de série auprès des industriels, Par la suite, chacun reprend son indépendance pour se consacrer à ses travaux respectifs. Les nouvelles orientations professionnelles de Pierre Guariche lui offrent la possibilité de collaborer à des programmes inédits d'architecture intérieure, nés de la politique d'aménagement du territoire. Cette thèse aborde donc le contexte social, politique et économique durant lequel il exerce son activité mais également des faits et des acteurs, ce qui ouvre de futurs champs à explorer dans l'histoire du design français. / This thesis puts forward a monographic approach to the career of Peter Guariche, designer-creator of French interior designer assemblies. The "Glorious thirty" represent a decisive turning point for this professional because they coincide with the beginning of industrialization in the furniture sector. The historical and political context explains his involveruent in the creation of full programs of articles intended to furnish standardized Reconstruction housing. He realizes that the mass production furniture, produced by industrial processes and at reasonable prices, can solve the effects of the failure of the policy of the French state, To adjust his "modem" furniture in the plan-type, it is inspired by the production of Arnerican designers and creates innovative standardized and rational objects on a technical and aesthetical level. ln 1954, he solicits Michel Mortier and Joseph-André Motte and creates with them L'Atelier de Recherches Plastiques. They understand that ail three young designers must unite around a common project: promoting their mass production furniture with manufacturers. Thereafter. each of them takes their independence and takes back their respective work. The ncw professional guidance of Pierre Guariche offers him the opportunity to collaborate on original interior architectural programs. stemming from the land use policy. This thesis deals with the social, political and economic contexts in which he practices, but also the facts and actors. which open up future areas to explore in the history of French design.

Demand for genetically modified food : theory and empirical findings

Kaye-Blake, William Henry January 2006 (has links)
As economies develop, novel products are created and markets for these products arise. Genetically modified food (GMF) is an example of such a novel product and provides economists with the opportunity to investigate an infant market. Of particular interest with GMF is the impact of consumer reactions on the market. The response of consumers to GMF and their willingness to pay for it has emerged as an important factor in the development of this technology. This research investigates these consumer responses. Prior research suggests that two aspects of consumer behaviour may be relevant for the GMF market. First, consumers may react differently to different types of GMF, so that some products are potentially more economically viable. Secondly, some consumers appear to prefer not having GMF at all. Consumer behaviour is often framed according to neoclassical economic theory. Consumer preferences over goods and the attributes of those goods are generally held to have certain properties. The aspects of consumers’ reactions to GMF noted above, however, may be in conflict with two properties of preferences in neoclassical theory. First, preferences over food attributes are not separable, but may interact with each other. Secondly, some consumers may have preferences regarding GMF that are not continuous. As a result, aggregate impacts of introducing GMF may be difficult to measure, which raises a third issue for investigation, aggregation. Finally, an alternative model of consumer behaviour is bounded rationality, which theorises that choices may be discontinuous as a result of specific protocols. It also suggests that consumers seek to make good-enough choices, rather than attempting to maximise their satisfaction. Thus, optimisation or maximisation is the fourth issue considered in this thesis. In order to investigate these properties of consumers’ preferences, a choice experiment survey was developed. The strength of a choice experiment for examining these issues is its focus on the impact of each product attribute on a respondent’s choices. Thus, it may be possible to identify potentially discontinuous choice patterns and to identify choices affected by interactions between GM technology and other food attributes. Results from a neoclassical analysis of the survey data suggest that some consumers consider the type of benefit created with GM technology in making their choices. In addition, one-quarter to one-half of respondents may have had discontinuous preferences with respect to GMF. Reactions to GMF appear related to respondents’ attitudes, but not to socio-economic or demographic descriptors. As a result, aggregate measures of the impact of GMF may not fully account for consumers’ responses. A boundedly rational model also has reasonable goodness of fit, and may provide a different perspective on consumer behaviour. It is hoped that the results of this research provide a better understanding of consumer behaviour regarding GMF and, by extension, of the process of consumer adoption of novel products. It is further hoped that this attempt to incorporate choice protocols into discrete choice analysis will provide a useful example for further research.

Tid i all oändlighet och förgänglighet. En studie av tidsanvändningen i Sverige sedan 1980-talet / Redundancy or Scarcity of Time? A Study of Time Use in Sweden since the 1980s

Andersson, Lina, Hultgren, Maja January 2005 (has links)
<p>This master thesis in economics discusses the time use of today as well as the observed trends in time use over the last 20 years in Sweden. This is done by analysing time-use and consumption data at the microeconomic level, i.e. by explaining individual behaviour given the economic assumption of a rational behaviour. We reach the conclusion that the value of time is an important explanatory variable concerning the rationality in that time is used differently by different individuals and in the changed use of time. Furthermore, other variables such as social norms and the process benefit of a certain activity, i.e. the satisfaction obtained from performing this activity, are also crucial determinants. In addition we discuss whether an increased value of time results in an increased level of stress, and we reach the conclusion that stress above all is attached to certain socioeconomic groups. However, we are of the opinion that the increased value of time can explain a perceived general increase in the speed of time. Finally, the thesis ends with a discussion in which time is linked to happiness and welfare, and we pose the question whether the indiviual uses his/her time in such a way that happiness is maximised. We conclude that it is difficult to use one’s time in this way, since it is impossible to know one’s total supply of time.</p>
