Quadros em movimento: O uso das fontes iconográficas no filme Os Bandeirantes (1940), de Humberto Mauro

Este artigo discute a utilização das fontes iconográficas enquanto estratégia de autenticação da narrativa cinematográfica através da análise de um dos blocos narrativos do filme Os Bandeirantes (1940), de Humberto Mauro. Tal filme teve a orientação geral de Edgar Roquette-Pinto, diretor presidente do Instituto Nacional de Cinema Educativo (INCE), e a coordenação histórica de Afonso de Taunay, historiador e diretor do Museu Paulista, mais conhecido como Museu do Ipiranga. A estratégia de utilização da iconografia enquanto documento histórico em Os Bandeirantes produzirá um curto-circuito com o trabalho de mise-en-scène de Humberto Mauro, gerando significados diversos daqueles que foram idealizados pelos produtores do filme.

Análise Narrativa em Trabalhos de História da Educação Matemática: algumas considerações

This paper presents some reflections on the use of narrative analysis as a possible approach to study the History of (Mathematics) Education, mainly to interpret historical situations and biographical data. Its perspective is linked to Walter Benjamin's ideas about the figure of the narrator and how the dialogue between narrator and historian can be seen. Following the perspective of another author, Benedito Nunes, we try to establish relations among narratives, fiction and historiography, also highlighting the ideas of Jorge Larrosa regarding the transmission of experiences. Finally, our focus is turned to Antonio Bolivar and his alternative statements about why and how analysis of investigations, in which narratives are the main source of data, can be done.

The effects of the social hierarchy destabilization on the foraging activity of eusocial wasp Mischocyttarus cerberus styx Richards, 1940 (Hymenoptera: Vespidae: Polistinae)

The genus Mischocyttarus comprises 245 species of neotropical basal eusocial wasps. They form small colonies (rarely more than few tens of individuals); castes are morphologically undifferentiated and determined behaviorally by agonistic interactions. The aim of this study was to verify the effects of the experimental disruption of social hierarchy on foraging activity of Mischocyttarus cerberus styx. We observed six colonies in postemergence phase and recorded data on the foraging activity under two experimental conditions: (1) removal of lower-ranked females and (2) removal of higher ranked females, except the queen. Our results showed that the removal of higher-ranked females had higher effect on the number of foraging trips of M. cerberus styx than the removal of lower-ranked females (the number of foraging trips/hour decreased by 66.4 and 32.7, resp.). Such results are likely due to the social organization of this species and the presence of a distinct class of females, which in this study were regarded as intermediates. Our data also showed that, irrespective of the hierarchical status of the females, the removal of two or three individuals affected significantly the number of foraging trips in this species.
