Afonso de Albuquerque e a primeira expedição portuguesa ao Mar Vermelho (1513)

Este artigo pretende analisar a primeira expedição portuguesa ao Mar Vermelho, capitaneada pelo governador Afonso de Albuquerque, em 1513. Quinhentos anos depois desta viagem, reavaliamos a política manuelina para o Mar Roxo, observando o ataque à cidade de Adém e a consecutiva entrada naquele mar. Através da correspondência de Albuquerque e da cronística da época, tentamos compreender os motivos da derrota no assalto àquela cidade portuária e a importância desta expedição na acção daquele governador e na estratégia imperial de D. Manuel I.

Visual politics of the estado novo realized on the Alameda Dom Afonso Henriques in Lisbon – the construction of ideal citizenship?

The stylistic categorization of the Estado Novo has been intensely discussed by Portuguese art historians. The square Alameda Dom Afonso Henriques in Lisbon (Alameda) can be seen as paradigmatic for the architecture of power of the Estado Novo. The Alameda forms a gardened valley between two hills. There you find two prominent and highly propagandist buildings: The Instituto Superior Técnico (IST) and the Fonte Luminosa are dedicated to modern sciences and respectively to the harmonious contribution of nature to the city. The iconography of the Alameda as well as its incorporation into the propagandist use of urban planning in the 1930s and 1940s exemplify the visual politics during Salazarism. Urban planning programs intended to create cities that would preserve the character of a traditional catholic society and at the same time answer to the need to modernize the country and evoke the image of a progressive state. Thus, public buildings and urban squares such as the Alameda contributed to design a corporate image and to the ‘spirit’ of the regime.

Revolution in Crisis: The Ruptures of Revolution and Ruptured Revolutions Through the Ruptures of Artistic Practice

This article proposes an investigation of the history and memory of the Carnation Revolution through the lens of contemporary art. Drawing upon the argument according to which history and memory are investigated by visual artists by means other, but no less relevant, than those of professional historians, this article will argue for the importance of attending to the visual, auditory, textual, object- and research-based ways in which artists from several generations and geographies have been unearthing the repressed histories and memories of the Carnation Revolution in Portugal and of anticolonial struggles, decolonization and post-independence nation-building in Mozambique, Guinea-Bissau and Angola. The discussion focuses on several works by Ângela Ferreira, but attention will also be paid to precursors in imaging the Revolution, such as Ana Hatherly, and to a younger generation of artists such as Filipa César, Kiluanji Kia Henda and Daniel Barroca.

Prevalência da C.trachomatis entre homens que fazem sexo com homens (HSH) que frequentam um centro clínico comunitário alternativo em Barcelona

RESUMO - Enquadramento: A infeção por Chlamydia trachomatis (CT) é considerada um grave problema de Saúde Pública. É causa de infeções sintomáticas tanto no homem como na mulher, bem como, de infeções assintomáticas que podem ter consequências muito graves a longo prazo. A presença de CT sem tratamento aumenta o risco de transmissão do vírus da imunodeficiência humana. Existem vários estudos publicados de prevalência da CT por todo o mundo, no entanto, estudos de prevalência da CT em populações assintomáticas, envolvendo homens que fazem sexo com homens (HSH) são raros na Europa. Assim, o presente estudo, ao estimar a prevalência e ao descrever as caraterísticas epidemiológicas e de conduta dos HSH, pretende contribuir para o plano de ação contra as IST´s e VIH na Catalunha, através de estratégias concretas para deteção e prevenção da CT. Métodos: Trata-se de um estudo observacional, transversal de prevalência da CT em HSH utentes de um serviço comunitário em Barcelona, com recurso a técnicas de diagnóstico de biologia molecular e a um questionário. Durante Março e Junho de 2015, foram recrutados 200 voluntários de um serviço comunitário em Barcelona que foram testados para CT e NG em três locais anatómicos através de uma PCR em tempo real utilizando o ensaio Anyplex™ CT/NG Real-time Detection. Resultados: O presente estudo permitiu uma caraterização da situação atual quanto á prevalência e aos fatores de risco associados á infeção por CT em HSH. A prevalência nesta população específica foi de 12,6% e os fatores risco associados foram o facto de serem VIH e praticarem sexo anal insertivo/recetivo com parceiro estável. Conclusões: Os resultados obtidos reforçam a necessidade do desenvolvimento de estratégias adequadas de controlo e prevenção da CT nesta população de risco, tais como: rastreios frequentes e tratamento dos casos positivos para quebrar a cadeia de transmissão, promoção da saúde, educação e notificação dos parceiros sexuais. Também demonstram a importância destes rastreios nos três locais anatómicos: uretra, reto e faringe.

Strategies of the small-scale fisheries on the Central Amazon floodplain

A multivariate approach was applied to data of small-scale fisheries developed in Central Amazon, using information about catch composition, environment, fishing gear and season of the hydrological cycle. The correspondence analysis demonstrated to be a good tool for the analysis related multispecies fisheries. The analysis identified patterns of use of fisheries resources by the riverine communities, showing the correlation between the environmental factors and the fishing strategy for the capture of target fish species, indicating the high level of empiric knowledge about the environment and fisheries.

Fishing territoriality and diversity between the ethnic populations Ashaninka and Kaxinawá ,Breu river, Brazil/Peru

This study describes the diversity and the subsistence fishing territoriality of traditional populations of a village Ashaninka and two Kaxinawá living at the margins of Breu River (Brasil/Peru). In general, samplings in the dwellings were carried out late in the afternoon, as the fishermen arrived in the village. The data were analysed in an exploratory way through the index of pondered dominance (ID%), by analysis of variance and by a correspondence analysis in order to determine the associations of the fish species and the fishing spots between the villages of the Indigenous Reserve. The results of the analysis of variance demonstrated that differences exist between the fish diversities of the catches. However, post-hoc tests only detected differences in diversities between the hand fishhook and the other fishing gears (bow and arrow, castnets and rotenone tingui). Although the use of bow and arrow resulted in a low capture (Kg), this fishing strategy is associated with a high fishing diversity, in terms of number of species. These results demonstrate that there is no overlap in the frequency of the visits to the fishing spots between the Ashaninka and Kaxinawá populations. This pattern is the same found for the correspondence analysis for the fish species, which describes the relationship between the deep pools environments exploited by the fishermen Ashaninka and Kaxinawá of Mourão. These ethnic populations still continue to maintain a strong cultural and cosmological tradition, with their territories defined in an informal way of the upper Juruá area.

Environmental determinants for natural regeneration of gallery forest at the Cerrado/Amazonia boundaries in Brazil

Natural regeneration and structure and their relationship to environmental variables were studied in three sections of a gallery forest, in Eastern Mato Grosso, Brazil (14º43′S and 52º21′W). The assumption was that natural regeneration is constrained by environmental determinants at all stages of development of the tree community. The objective was to analyse the forest structure and to verify the relationship between species distribution and abundance at different stages of regeneration and environmental variables. In each section, 47 contiguous (10x10m) permanent plots were established to sample trees (gbh≥15cm), following a systematic design. Seedlings (0.01 to 1m height), saplings (1.01 to 2m) and poles (from 2.01m height to gbh<15cm) were sampled in sub-plots of 1x1m, 2x2m and 5x5m, respectively. In each plot, soil properties, gaps projection, bamboos, rocky cover, declivity and depth of ground watertable were determined. The relationships between the environmental variables with trees and seedling communities were assessed by canonical correspondence analysis. In spite of the sections being near to each other, they presented large differences in floristics, structure and site conditions. The forest soil presented a low cation exchange capacity and a high level of Al saturation. The occurrence of bamboos and gaps and the depth of ground watertable limited the occurrence of poles and trees. The high degree of structural heterogeneity for each regeneration category was related primarily to a humidity gradient; but soil fertility (Ca+Mg) was also a determinant of seedling and sapling communities.

Use of the flooded forest by fish assemblages in lakes of the National Park of Anavilhanas (Amazonas, Brazil)

We evaluated diversity and distribution of fish species in two habitats: flooded forest and open water of lakes of Rio Negro. Each of four lakes within the Anavilhanas Archipelago was sampled three times from 2009-2010. Species diversity generally was higher in flooded forests and at night, according to correspondence analysis. Predators were most active at night, but showed no preference between the flooded forest and open water habitats. Omnivores, filter feeders, and detritivores were most active during the day.

Species richness and community structure of arboreal spider assemblages in fragments of three vegetational types at Banhado Grande wet plain, Gravataí River, Rio Grande do Sul, Brazil

The taxonomic composition, observed and estimated species richness, and patterns of community structure of arboreal spider assemblages in eleven sites surrounding the "Banhado Grande" wet plain in the state of Rio Grande do Sul, Brazil, are presented. These sites represent three different vegetational types: hillside (four sites), riparian (five sites) and flooded forests (two sites). The spiders were captured by beating on foliage and "aerial litter". A sample was defined as the result of beating on twenty bushes, tree branches or "aerial litter" clusters, which roughly corresponds to one-hour search effort per sample. Fifty five samples (five per site) were obtained, resulting in an observed richness of 212 species present as adult or identifiable juveniles. The total richness for all samples was estimated to be between 250 (Bootstrap) to 354 species (Jackknife 2). Confidence intervals of both sample and individual-based rarefaction curves for each vegetation type clearly indicated that flooded forest is the poorest vegetation type with respect to spider species richness, with hillside and riparian forests having a similar number of species. The percentage complementarity between the eleven sites indicated that all sites contain a distinct set of species, irrespective of their vegetation types. Nevertheless, the spider assemblages in riparian and hillside forests are more similar with respect to each other than when compared to flooded forest. Both cluster and nonmetric multidimensional scaling analyses showed no strong correspondence between the spider arboreal fauna and the three vegetation types. Moreover, a Mantel test revealed no significant association between species composition and geographic distance among sites.

Macroinvertebrates under stochastic hydrological disturbance in Cerrado streams of Central Brazil

In the Cerrado vegetation, where the seasonal is well defined, rainfall has an important role in controlling the flow of streams and consequently on the structure of macroinvertebrates community. Despite the effects of rainfall associated with seasonality are well studied, little is known about the effects of stochastic rains on the community. In the present study we evaluated the structure and faunal composition of four first-order streams in Central Brazil during the dry season in two years, with and without stochastic rains. Community sampling was done by colonization of boards of high density polyethylene (HDPE), removed after one month submerged in streams. Analysis of Variance (ANOVA) performed indicated no difference in rarefied richness between the two periods, different from numeric density of organisms that was higher in the period without disturbance; moreover, the Detrended Correspondence Analysis (DCA) revealed differences in faunal composition between the two periods. Our results indicate that stochastic rainfall is an important factor in structuring the macroinvertebrates community in studied region.
