In America by the 1930s, albino rats had become a kind of generic standard in research on physiology and behavior that de-emphasized diversity across species. However, prior to about 1915, the early work of many of the pioneer rat researchers in America and in central Europe reflected a strong interest in species differences and a deep regard for diversity. These scientists sought broad, often medical, generality, but their quest for generality using a standard animal did not entail a de-emphasis (...) of organic diversity. They chose white rats as test animals for two primary reasons. First, rats develop very slowly. They therefore made features of physiological, neural and psychological development accessible to the experimental method at a time when its application to the phenomena of development remained controversial. Secondly, rats were thought to have unusually strong sex drives. For this reason they became central to the experimental study of sexuality and, in the work of the reproductive physiologist Eugen Steinach, sexual development. Connections among three research institutes that stressed experimental approaches to the study of brain and development demonstrate the importance of the rat's institutional role. As the emphasis on experimentation in the study of development grew, two of these institutes bred rats to provide uniform materials. Eventually, however, their reasons for selecting rats were lost; and the ready availability of a uniform test animal led to a shift in scientists' presumptions about diversity, as the standard rat became a tool for assuring generality.

Qu'est-ce qui relie, dans les tréfonds de notre être-au-monde, les entreprises créatives de la musique et des mathématiques? Qu'est-ce qui fait des mathématiques une musique des nombres et de la musique une mathématique des sons? Cet ouvrage essaye de répondre à ces questions. Prenant son départ dans la phénoménologie de l'acte créatif, l'analyse atteint la région où la phénoménologie touche la dimension du symbolique. C'est la volonté de rester dans ce no man's land, là où les dimensions du phénoménologique et (...) du symbolique s'entrecroisent et se mélangent, qui permet d'apercevoir la place où chaque homme impliqué dans l'activité créatrice trouve ses moyens et ses limites. La constitution d'un espace-temps qui est, en même temps, mathématique et musical, est le centre de cette entreprise. Le milieu où le musical et le mathématique se transforment et se confondent l'un dans l'autre devient alors le lieu où l'analyse peut étudier des objets qui ne sont pas complètement donnés, des objets qui demeurent in fieri. Ces constitutions partielles, toujours sur le point de se condenser en produits de la langue logique ou de disparaître dans une sorte de babillage créatif, assurent la tenue et la possibilité des institutions symboliques des mathématiques et de la musique. Mais surtout ces objets assurent l'étrange capacité de ces deux institutions symboliques : la capacité de se nourrir et de proliférer mystérieusement de et sur elles-mêmes, en y trouvant les raisons de leur futur.

En la literatura publicada a lo largo del siglo XX y lo que va del XXI encontramos de manera constante lo que podemos denominar una serie literaria sobre el tema de la homosexualidad. La historia literaria costarricense muestra, en los inicios del siglo XX, el caso de Jenaro Cardona, de manera particular con La esfinge del sendero (1914). Más adelante, apenas pasada la primera mitad de siglo, encontramos el caso de José León Sánchez con La isla de los hombre solos (...) (1963), en donde la homosexualidad es presentada como parte de los arrebatosy de la violencia carcelaria.Teníamos que llegar a las últimas décadas del siglo pasado para que, de alusiones que marginalizaban aún más todo lo que tuviera que ver con la sexualidad, se pasara a una nueva manera de comenzar a sacar del closet literario, ya no solo el tema de la homosexualidad, sino en general el de la sexualidad misma. El valor enunciativo de la publicación de esta literatura plantea una relectura del Estado costarricense mismo y del papel de sus instituciones. De ahí la significación de ese gesto fundante y provocador, producto de esta nueva serie de textos en la Costa Rica contemporánea, de una manera como no había sucedido antes en el país. (shrink)

In the development of Roman Catholic social thought from the teachings of the scholastics to the modern social encyclicals, changes in normative economics reflect the transformation of an economic terrain from its feudal roots to the modern industrial economy. The preeminence accorded by the modern market to the allocative over the distributive function of price broke the convenient convergence of commutative and distributive justice in scholastic just price theory. Furthermore, the loss of custom, law, and usage in defining the boundaries (...) of economic behavior led to a depersonalization of economic relationships that had previously provided effective informal means of protecting individual well-being. Hence, recent economic ethics has had to look for nonprice, nonmarket mechanisms for distributive justice. This is reflected, for example, in the shift in attitude from the medieval antipathy toward unions to the contemporary defense of organized labor on moral grounds. (shrink)

Rooted in a reasoned understanding of what it is to be a human being in community, Catholic social principles are accessible to a pluralistic, even secular, audience. Instead of being used separately in an ad hoc manner, these principles can be applied as a single analytical framework in examining ethical questions. Doing so allows the manifold dimensions of social problems to surface. The paper applies this framework on the issue of whether currency markets ought to be taxed in order to (...) deter speculation.

O presente artigo apresenta os principais resultados do projeto de pesquisa “Mídia Cidadã e Desenvolvimento Sustentável: mapeamento e análise de rádios comunitárias em áreas de pressão socioambiental na Amazônia”, que busca entender a dimensão e o papel potencial das rádios comunitárias nos embates discursivos pelo desenvolvimento da região amazônica. O objeto da investigação são rádios comunitárias situadas em áreas de potencial conflito socioambiental na Amazônia Legal, o que inclui disputas por território ou pelo uso de recursos naturais, considerando-se grandes obras (...) de impacto, mas também Unidades de Conservação e Terras Indígenas nos noves estados da região. Como produto central do projeto foi gerada uma cartografia digital sobre comunicação cidadã e desenvolvimento sustentável na região, na perspectiva de gerar insumos para o fortalecimento da comunicação comunitária como espaço de contra-hegemonia midiática e consequente empoderamento de grupos locais nas decisões que afetem seu bem-estar.
