Cabo Verde consiste num arquipélago situado no oceano Atlântico e tem uma extensão geográfica de 4.033 Km2. Segundo dados de 2006 estima-se uma população de 518.000 habitantes. O país está classificado pelo Banco Mundial como de renda média baixa. A expectativa de vida média ao nascer é de 72 anos. Segundo pesquisa de 2002/03, 37% da população foi considerada pobre e 20% muito pobre.1 A maior parte do sistema de saúde está descentralizada, o que facilita o acesso da população aos serviços de saúde.

Evidence of a sport-specific hierarchy of protective factors against doping would thus be a powerful aid in adapting information and prevention campaigns to target the characteristics of specific athlete groups, and especially those athletes most vulnerable for doping control. The contents of phone calls to a free and anonymous national anti-doping service called 'ecoute dopage' were analysed (192 bodybuilders, 124 cyclists and 44 footballers). The results showed that the protective factors that emerged from analysis could be categorised into two groups. The first comprised 'Health concerns', 'Respect for the law' and 'Doping controls from the environment' and the second comprised 'Doubts about the effectiveness of illicit products, 'Thinking skills' and 'Doubts about doctors'. The ranking of the factors for the cyclists differed from that of the other athletes. The ordering of factors was 1) respect for the law, 2) doping controls from the environment, 3) health concerns 4) doubts about doctors, and 5) doubts about the effectiveness illicit products. The results are analysed in terms of the ranking in each athlete group and the consequences on the athletes' experience and relationship to doping. Specific prevention campaigns are proposed to limit doping behaviour in general and for each sport.

Este trabalho centra-se no estudo das dinâmicas familiares e intergeracionais das mulheres africanas em contexto de bairro, tendo na sua base a esfera cultural. O seu principal objectivo é contribuir para a compreensão do objecto de estudo em questão, à luz de três dimensões de análise: familiar, pessoal e espacial e posteriormente, repensar a possibilidade de adopção de novos quadros de valores e perspectivas, em relação ao conceito de ghetto/bairro e ao papel da mulher africana no processo de reprodução cultural. Neste sentido foi desenvolvida uma abordagem multidisciplinar para compreender as dinâmicas familiares e intergeracionais a partir dos enquadramentos teóricos e conceptuais existentes. O estudo empírico foi desenvolvido através de um trabalho de natureza qualitativa, recorrendo-se à análise de conteúdo de entrevistas semi-directivas para assim dar visibilidade e compreensibilidade às práticas e experiências existentes no bairro. Fazem parte da amostra um grupo de mulheres africanas residentes em bairros sociais das zonas de Lisboa e Vale do Tejo constituída por 8 jovens mulheres, com idades compreendidas entre 16 e os 25 anos e 8 avós com mais de 50 anos. Como conclusão reconhecemos a necessidade de representar os ghettos de hoje uma vez que, após esta investigação, novas questões orientadoras poderiam ser formuladas, já que não se conheceu definições únicas ou consensuadas sobre o mesmo.

Micas are commonly used in Ar-40/Ar-39 thermochronological studies of variably deformed rocks yet the physical basis by which deformation may affect radiogenic argon retention in mica is poorly constrained. This study examines the relationship between deformation and deformation-induced microstructures on radiogenic argon retention in muscovite, A combination of furnace step-heating and high-spatial resolution in situ UV-laser ablation Ar-40/Ar-39 analyses are reported for deformed muscovites sampled from a granitic pegmatite vein within the Siviez-Mischabel Nappe, western Swiss Alps (Penninic domain, Brianconnais unit). The pegmatite forms part of the Variscan (similar to 350 Ma) Alpine basement and exhibits a prominent Alpine S-C fabric including numerous mica `fish' that developed under greenschist facies metamorphic conditions, during the dominant Tertiary Alpine tectonic phase of nappe emplacement. Furnace step-heating of milligram quantities of separated muscovite grains yields an Ar-40/Ar-39 age spectrum with two distinct staircase segments but without any statistical plateau, consistent with a previous study from the same area. A single (3 X 5 mm) muscovite porphyroclast (fish) was investigated by in situ UV-laser ablation. A histogram plot of 170 individual Ar-40/Ar-39 UV-laser ablation ages exhibit a range from 115 to 387 Ma with modes at approximately 340 and 260 Ma. A variogram statistical treatment of the (40)Ad/Ar-39 results reveals ages correlated with two directions; a highly correlated direction at 310 degrees and a lesser correlation at 0 degrees relative to the sense of shearing. Using the highly correlated direction a statistically generated (Kriging method) age contour map of the Ar-40/Ar-39 data reveals a series of elongated contours subparallel to the C-surfaces which where formed during Tertiary nappe emplacement. Similar data distributions and slightly younger apparent ages are recognized in a smaller mica fish. The observed intragrain age variations are interpreted to reflect the partial loss of radiogenic argon during Alpine (similar to 35 Ma) greenschist facies metamorphism. One-dirnensional diffusion modelling results are consistent with the idea that the zones of youngest apparent age represent incipient shear band development within the mica porphyroclasts, thus providing a network of fast diffusion pathways. During Alpine greenschist facies metamorphism the incipient shear bands enhanced the intragrain loss of radiogenic argon. The structurally controlled intragrain age variations observed in this investigation imply that deformation has a direct control on the effective length scale for argon diffusion, which is consistent with the heterogeneous nature of deformation.
