Neste artigo são apresentados alguns desafios e alternativas encontradas na organização de documentos referentes à imigração pós-Segunda Guerra Mundial, depositados no acervo do Memorial do Imigrante em São Paulo. A organização de um conjunto documental diversificado e disperso foi acompanhada da necessidade de inserção dos registros inscritos na documentação em uma base informatizada. Este artigo descreve ambos os momentos do trabalho de organização deste acervo, dando ênfase ao processo de informatização como elemento fundamental para disponibilizar as informações à pesquisa.

Este livro tem como objetivo verificar se na formação dos professores na área de Educação Física há também espaço para a difusão de saberes que vão além dos conhecimentos técnico-científicos. Os autores partem do princípio de que modernamente é dado como certo que a instabilidade dos ambientes da prática docente exige dos professores mais do que conhecimentos teóricos: demanda deles também que trabalhem com elementos como a incerteza e a complexidade, diante de situações como o imprevisto, a urgência, a dispersão, a indisciplina e a dificuldade para a compreensão e a aprendizagem. Tais situações obrigariam o professor a emitir juízos e tomar decisões, quase sempre de caráter prático. A conclusão dos pesquisadores é, no entanto, de que os cursos de formação dos profissionais de Educação Física continuam privilegiando as disciplinas teóricas, e trabalham pouco os chamados saberes práticos. O estudo foi baseado em entrevistas com estudantes e professores e em análise documental e interpretativa de situações práticas do ensino da disciplina em três escolas municipais de Indaiatuba (SP). Tratou-se, portanto, de uma pesquisa de natureza qualitativa e do tipo descritiva, e não de uma investigação quantitativa

The Brazilian campos rupestres (high-altitude grasslands) are very important on the world conservation scenario because of high species richness and endemism. These grasslands are regarded as threatened ecosystems due to intense, on-going disruption by man's activities. The aim of this study was to describe the reproductive and vegetative phenological patterns of six shrub species endemic to these grasslands in the Espinhaço Range, sympatric in Serra do Cipó, MG. We tested the relationship between species phenophases and local climate seasonality. We expect that the species phenophases are strongly correlated with variations of the dry and wet seasons. Observations were conducted monthly on reproductive (flowering, fruit production and dispersal) and vegetative (leaf fall and budding) phenophases. Given the combination of reproductive phenology, vegetative phenology, and seasonality, we observed four phenological strategies for the six species. Therefore this study revealed great diversity in phenological patterns, even when considering the small number of species sampled. Moreover, all species showed a significant seasonal pattern for the reproductive phenophases, with high concentrations of species reproducing during a given season, suggesting a key role of climate in defining phenological patterns in the campo rupestre grasslands.

Physiological responses like the thermal requirements for germination may be influenced during seed formation by environmental conditions such as water availability and temperature. Here we analyzed germination of embryos of Ingavera subsp. affinis from different sources in response to various temperature regimes, including calculation of degree days and accumulated rainfall during development and maturation. Embryos were taken from ripe fruits collected on trees located in São Paulo and Minas Gerais, and were analyzed as to germination, water content and dry matter content. The results showed that the origin of the embryos was related to variation in response under sub-optimal temperatures. Depending on the origin, I.vera subsp. affinis embryos were able to germinate even at low temperatures (10 to 15 ºC), with better performance attained from 20 to 25 ºC. This variation may be associated, among other factors, to environmental conditions during maturation and to the maturation stage at seed dispersal.

The literature has pointed out the educational deficits of Brazilian public schools, the complexity of school management, and the need for better qualification for the exercise of this function. Considering this perspective, the present research questions: How is school management being contemplated within the initial pedagogical training in the state of Paraná? In this sense, this article aims to survey and analyze how school management in professional training in public universities Educator of Paraná is being contemplated after the publication of the National Curriculum Guidelines for the Education Course (DCNP). The study works with a qualitative approach to carry out, in the one hand, the bibliographic survey and systematization and, on the other hand, the survey, systematization and analysis of some elements in the political-pedagogical projects of different public universities. The data collected in six public universities show a significant oscillation between the workload aimed at the knowledge of School Administration and a variety of covered contents. Such differences may reflect the scope of the National Curriculum Guidelines as well as the present theoretical dispersion regarding the current knowledge on School Administration.

Diatraea saccharalis Fabr. (Lepidoptera: Crambidae) is a major sugarcane pest in Brazil. The management of infested areas is based on the release of Cotesia flavipes (Cameron) (Hymenoptera: Braconidae), a parasitoid of D. saccharalis larvae, but there are doubts about the effectiveness of C. flavipes, primarily regarding its rate of dispersal in sugarcane fields. Thus, the objective of this study was to evaluate the dispersal of C. flavipes in a sugarcane field and suggest a release method that provides higher parasitoid efficiency. The study was carried out in four areas of approximately 1 ha, in which stalk pieces containing 20 D. saccharalis larvae were distributed in a rectangular grid, and 12,000 C. flavipes adults were released at four points, that were 50 m apart and 25 m from the field border. Three days later, the D. saccharalis larvae were recovered and kept in the laboratory until they reached pupal stage or C. flavipes emergence. Parasitism varied from 13.2% to 42.8%. The random distribution of parasitized larvae was found in one assay. In three areas, the parasitized larvae showed an aggregated distribution, with a range of 15 to 25 m. Since the parasite's success is directly linked to parasitoid dispersion, it would be interesting to move the release points to 30 m from each other because the dispersal may happen in a 15 m radius.
