A produção técnico-científica de James Precott Joule: uma leitura a partir da epistemologia de Ludwig Fleck

This paper aims an epistemologically analysis of the attempt of James Prescott Joule to replace the steam engine by the electric one. In this historical analysis, we use the epistemological categories: style of thinking, collective thinking, intercollective circulation of ideas and practices,Joule and other technicians in Machester received in that time financial incentives from governments and industry to replace the steam engine by the electric one, since it was in Manchester a culture of the technique of the accuracy and precision in which Joule was immersed, which allowed us to initially identify the styles of techniques thinking and experimental efficiency. However, Joule could not replace the steam engine by the electric; and the awareness of the problems faced by him, in the attempt to make such a substitution, led him to seek, through an intercollective circulation of ideas and practices, such as the studies of Faraday and Jacobi, a change of direction in his researches. According to our analysis, what happened was a change of style from a technical to a scientific thinking. In this sense, Joule began to investigate issues of a scientific nature, as the Joule’s effect and the mechanical equivalent of heat, which contributed significantly to the establishment of the principle of conservation of energy. We present here the contributions of this epistemological analysis to the discussion of questions of the nature of science in the basic education and for the training of physics teachers.

Book Review of A Dazzle of Dragonflies by Forrest L. Mitchell and James L. Lasswell

Dragonflies are beautiful animals, important predators in and around aquatic environments, and often good indicators of ecosystem health. Stimulated by digital photography, close-focusing binoculars, and many new regional field guides, the study of dragonflies has exploded in the last ten years. Most importantly, the Internet has connected beginners with experts; observers from everywhere now share their experiences. Here is a book that puts it all on paper.

Immatures of Dicrepidius Eschscholtz, 1829 and Dipropus Germar, 1839 (Elateridae, Elaterinae, Ampedini: Dicrepidiina)

The larva of Dicrepidius ramicornis (Palisot de Beauvois) and pupa of Dipropus brasilianus (Germar) are described. The larva of D. brasilianus is redescribed. The immatures of both species are illustrated. Comparisons among the known larvae of Dipropus species and between the two genera are presented. A provisional key to Dicrepidiina genera with known larvae is provided.

A new species of Leporinus Agassiz, 1829 from the upper Rio Paraná basin (Characiformes, Anostomidae) with redescription of L. elongatus Valenciennes, 1850 and L. obtusidens (Valenciennes, 1837)

Leporinus obtusidens Valenciennes, 1837 and L. elongatus Valenciennes, 1850 are redescribed based on the type specimens, including those of their junior synonyms, and recently collected specimens. Leporinus obtusidens is considered to be widespread, occuring in the river drainages of La Plata, São Francisco, and Parnaíba. Leporinus aguapeiensis Campos, 1945, described from the upper Rio Paraná, and L. silvestrii Boulenger, 1902, described from the Rio Paraguay, are considered junior synonyms of L. obtusidens. Leporinus elongatus is endemic to the Rio Jequitinhonha and Rio Pardo, two eastern Brazilian river basins, and the locality cited for the lectotype, Rio São Fransico, likely to be erroneous. Leporinus crassilabris Borodin, 1929, and L. crassilabris breviceps Borodin, 1929, both described from the Rio Jequitinhonha, are considered junior synynoms of L. elongatus. A new species of Leporinus, endemic to the upper Rio Paraná, very similar and sometimes mistaken with L. obtusidens, is formally described. In addition, comments on Leporinus pachyurus Valenciennes, 1850 and on L. bimaculatus Castelnau, 1855 are provided, and a lectotype for L. bimaculatus is selected.

A magia desencantada: Henry James e o caso de "Os amigos dos amigos"

Por meio do exame do conto "Os amigos dos amigos" ("The friends of the friends"), de Henry James, bem como de seu processo de criação, este trabalho investiga a categoria do duplo confrontando as suas fontes primitivas com sua adoção na narrativa moderna - um confronto que nos permite sugerir uma chave de interpretação para a ficção jamesiana, e ainda discutir a presença do sobrenatural numa sociedade que privilegia o espetáculo, a publicidade, a novidade, o consumo e o progresso.

O modelo keynesiano de James Meade

Este artigo reavalia o "modelo simplificado" da Teoria Geral de Keynes elaborado por James Meade e procura complementar alguns dos argumentos teóricos que Meade deixou apenas indicados. O artigo também responde às solicitações de Frisch a Meade, quanto à explicação do significado de estabilidade e à explicitação dos pressupostos que garantem suas conclusões. Além disso, apresenta alguns dos cálculos não desenvolvidos por Meade, e, quando necessário, suas devidas correções.
