Apropriações, conflitos e negociações de gênero, classe e sorologia: etnografando situações e performances no mundo social do HIV/AIDS (Rio de Janeiro)

Considerando o caráter multifacetado e socialmente heterogêneo da epidemia do HIV/AIDS, gostaria de refletir sobre as formas pragmáticas de apropriação, negociação e conflito de gênero em termos das disposições possíveis de masculinidade e feminilidade ou, ainda, suas amplas combinações entre homens e mulheres de diferentes identidades sexuais e diversos status sorológicos. Os contextos a serem explorados e descritos são aqueles particulares ao mundo social da AIDS, incluindo tanto o cotidiano de uma ONG AIDS específica, bem como os que se apresentam em situações tanto públicas como privadas na cidade do Rio de Janeiro. Pretendo discutir como novas subjetividades podem se constituir a partir dos usos de categorias sexuais e sorológicas, valores morais e de expressões performativas de gênero

Doença, ativismo biossocial e cidadania terapêutica: a emergência da mobilização de pessoas com HTLV no Brasil

O artigo aborda a emergência da mobilização social e política de pessoas infectadas pelo HTLV, na década de 2000. Com fortes vínculos com o ativismo de HIV/Aids, pessoas com HTLV e seus grupos e organizações engendraram práticas sociais, discursos e identidades que contribuem para se pensar em termos teóricos e históricos sobre a questão das biossocialidades e da cidadania terapêutic

O que é uma gestão universitária eficiente? a construção de critérios objetivos que delimitam o princípio da eficiência em Universidades Federais Brasileiras / What is an efficient university management? the construction of objective criteria that delimit the principle of efficiency in Brazilian Federal Universities

O presente estudo visa identificar e analisar critérios objetivos que indicam uma gestão eficiente de uma Universidade Federal. A eficiência, além de ser um princípio da Administração Pública, previsto na Constituição Federal Brasileira, é relevante para otimizar recursos e gastos, sobretudo com a redução orçamentária disposta pela Emenda Constitucional n.º 95/2016. Para atender ao referido objetivo de pesquisa, foi empregada a análise por triangulação de métodos a partir de entrevistas abertas, questionários e pesquisa bibliográfica sistematizada. A partir do exposto, foram identificados vinte e cinco itens que indicam uma gestão universitária eficiente, organizados em cinco categorias. Os resultados indicaram que as Universidades Federais, embora adotem predominantemente o modelo burocrático de gestão pública, seus servidores e usuários desejam que seja implementado o modelo gerencial de administração pública que se assemelha a uma instituição privada, com produtividade e uma prestação rápida de serviços. Já o modelo de gestão social, com vista à participação democrática, não foi considerado como sinônimo de eficiência. Contudo, não se deve sobrelevar ao extremo a concepção gerencial de gestão pública, já que há outros valores relevantes na Universidade, por ser um espaço de convivência, de posição político-ideológica que não são facilmente mensuráveis por números

Geography and ecology shape the phylogenetic composition of Amazonian tree communities

Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location: Amazonia. Taxon: Angiosperms (Magnoliids; Monocots; Eudicots). Methods: Data for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran\u27s eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny. Results: In the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R$^{2}$ = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R$^{2}$ = 28%). A greater number of lineages were significant indicators of geographic regions than forest types. Main Conclusion: Numerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions

Mapping density, diversity and species-richness of the Amazon tree flora

Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
