No capítulo X de A Estrutura das Revoluções Científicas (1962) de Thomas Kuhn o conceito de paradigma figura como elemento filosófico central na tensão que se estabelece entre o âmbito perceptivo/cognitivo versus o âmbito ontológico do “problema da mudança de mundo”. No presente artigo, apresento alguns desdobramentos do conceito de paradigma com o objetivo de indicar dois sentidos principais para o termo subjacentes às formulações kuhnianas no capítulo X e que são desenvolvidos na obra tardia do autor, a saber: (1) (...) o ‘paradigma’ como exemplar, apresentado em “Postscript – 1969” (1970) e “Seconds thoughts on paradigms” (1977); e (2) o ‘paradigma’ como léxico, apresentado principalmente, em, “Metaphor in science” (1979), “Commensurability, comparability, communicability” (1983), “Possible worlds in history of science” (1989), “The road since Structure” (1990) e “Afterwords” (1993). Através do conceito de exemplar, explicito a função cognitiva que os paradigmas exercem nos membros das comunidades científicas: a singularidade dos exemplares reside não apenas no fato de eles serem exemplos-padrão para os membros de uma comunidade, mas em serem expressão de um processo cognitivo mais geral que já está pressuposto no desenvolvimento da atividade científica. Através do conceito de léxico, explicito a função constitutiva dos paradigmas como princípios a priori, porém dinâmicos e relativizados, como condições de possibilidade para a experiência do conhecimento, sendo, em particular, determinantes na experiência do sujeito no âmbito científico. Nesse sentido, a articulação teórica proposta nesse artigo evidencia que a análise do empreendimento científico na Estrutura considera processos cognitivos e ontológicos do sujeito epistêmico expressos por meio do conceito de paradigma. No entanto, essa compreensão é obscurecida diante do emprego polissêmico e impreciso do termo no decorrer de toda a obra e que se apresenta de modo particularmente conflitante no capítulo X.

The roles companion animals have played in our lives has dramatically changed over the last few decades. At the same time, the terms we use to describe both the people and animals in these human-animal relationships have also changed. One example includes the use of the terms ‘owner’ or ‘guardian’ to refer to the human caretaker. While preferences by society appear to indicate increased interest in referring to companion animal caretakers as ‘guardians’, others have cautioned against its use or attempted (...) to restrict it. Additionally, the use of animal welfare terminology has direct implications for how we conduct both welfare research and practice. Our paper examines the use of ‘owner’ and ‘guardian’ with respect to (1) the implications for changing terminology on the function, clarity and uniformity of their use, and (2) the ethical and welfare impact that coincides with each term’s use. Our goal is to propose terminological considerations that could influence future welfare research, as well as help guide our interactions with companion animals. (shrink)

The most expressive account of explanations in neuroscience is currently the causal-mechanistic model formulated by Carl Craver. According to him, explanations in neuroscience describe mechanisms, in other words, it points out how parts organize themselves and interact to engender the phenomenon. Furthermore, neuroscience is unified as scientists from different areas that compose it work together to develop mechanisms. This model was extensively discussed in the last years and several criticisms were raised towards it. Still, it remains as the soundest model (...) for explanations in neuroscience nowadays. This paper is presented as a review of this model, as well as the critiques worked out against it and finishes with a brief consideration of the problem of explanation in neuroscience. (shrink)

Public decisions concerning large projects with detrimental environmental or heritage impacts involve value conflicts which stem from the diverse interests and variety of ways of evaluating the costs and benefits of such projects. They are also framed by institutionalised procedures and practices which favour certain concerns to the detriment of others. This paper aims to contribute towards a better understanding of how these procedures and practices, namely decision support tools such as the Environmental Impact Assessment (EIA), tend to shape public (...) decision-making processes in particular ways. It draws on a study of the public controversy surrounding the Foz Tua dam in Portugal, with a focus on the values upheld by the different parties in the controversy and their interplay in the production of justifications, specifically the actors’ positions on values and value conflicts and the restrictions posed by institutionalised public decision-making procedures on the expression and consideration of certain values.
