Variation of the Chlorophyll a Related to Sea Surface Temperature, Wind and Geostrophic Currents in the Cape Verde Region Using Satellite Data

We present a comparative analysis of satellite derived climatologies in the Cape Verde region (CV). In order to establish chlorophyll a variability, in relation to other oceanographic phenomena, a set of, relatively long (from five to eight years), time series of chlorophyll a, sea surface temperature, wind and geostrophic currents, were ensembled for the Eastern Central Atlantic (ECA). We studied seasonal and inter-annual variability of phytoplankton concentration, in relation to the rest of the variables, with a special focus in CV. We compared the situation within the archipelago with those of the surrounding marine environments, such as the North West African Upwelling (NWAU), North Atlantic Subtropical Gyre (NASTG), North Equatorial Counter Current (NECC) and Guinea Dome (GD). At the seasonal scale, CV region behaves partly as the surrounding areas, nevertheless, some autochthonous features were also found. The maximum peak of the pigment having a positive correlation with temperature is found at the end of the year for all the points in the archipelago; a less remarkable rise with negative correlation is also detected in February for points CV2 and CV4. This is behavior that none of the surrounding environments have shown. This enrichment was found to be preceded by a drastic drop in wind intensity (SW Monsoon) during summer months. The inter-annual analysis shows a tendency for decreasing of the chlorophyll a concentration.

Girls’ Education: Keeping Girls in School. ( A Literature Review with Implications for Girls’ School Attendence in Cape Verde)

Education plays a very important role in society’s development in order to promote good citizenship and individual rights and freedom. To this end, it is fundamental that girls be included in the education process. Inmost developed and developing countries, theoretically, both males and females have access to education. Cape Verde is no exception; however, the reality is that even in Cape Verde, promoting girls’ education and creating conditions to motivate girls to stay in school remains a challenge. Whereas girls have access to education many girls drop out for gender-related reasons. This paper will investigate girls’ education initiatives in general, and Cape Verde specific to offer recommendations and strategies to keep girls in school.

Racial Stereotypes in Fictions of Slavery: Uncle Tom´s Cabin by Harriet Beecher Stowe and O Escravo by José Evaristo D’ Almeida

Most stereotypes about Africans and their descendants started with colonialism in the fifteenth century. The encounter between Africans and Europeans facilitated the creation of myths and stereotypes about the colonized peoples, which were made effective through the naturalization of differences. The relationship between skin color and slavery developed to produce a racialized system of forced labor on which colonialism depended for its survival. Stereotypes functioned to legitimize colonial authority by building the notion that the colonizer ruled over the colonized because of an innate superiority. Therefore, stereotyping is an effective "discursive strategy" (Bhabha) based on fixity and repetition with the aim of controlling the other. Harriet Beecher Stowe’s Uncle Tom’s Cabin and José Evaristo D’Almeida O Escravo both denounced the evils of slavery in the United States of America and Cape Verde respectively, claiming for the end of the institution. However, they are both ambivalent towards slaves and blacks, being unable to envisage social equality for the two races. Both authors construct their black characters as stereotypical others, but they depict the light-skin characters as superior both culturally and physically. The bi-racial characters are portrayed as the ones who possess beauty and intelligence as an inheritance from their European ancestry, while blacks are relegated to the margins. We need to consider, however, that slavery in Cape Verde had different characteristics from its counterpart in the United States of America. In Cape Verde the Africans outnumbered the Europeans and that circumstance favored miscegenation and the emergence of forms of mixed culture, which came to be seen as positive and natural. In the United States of America miscegenation was regarded as a taboo since early. And even after Emancipation, “the one-drop rule” made the offspring of an African descendant black, however 'white' he or she might be.

Mini-STRs em genética forense

A análise do ADN baseada nos STRs (Short Tandem Repeats) tem provado ser uma ferramenta extremamente útil em estudos forenses. A aplicação dos multiplex de STRs resulta em perfis genéticos completos, para a maior parte das amostras, desde que contenham uma quantidade apreciável de ADN. Contudo, em amostras com ADN degradado, a análise tornase mais complicada, uma vez que os STRs com maior peso molecular (acima dos 250 pb), podem não ser amplificados nestas condições. Como a metodologia de Mini-STRs não estava, ainda, implementada nos Laboratórios Forenses portugueses, o objectivo principal deste estudo consistiu na aplicação de um multiplex, designado por Mini-SGM, que contém os marcadores TH01, FGA, D18S51, D16S359, D2S1338 e a Amelogenina, para implementação na prática forense, tendo os resultados sido comparados com a metodologia de rotina. O trabalho experimental teve início com um estudo populacional, que compreendeu uma amostra de 110 indivíduos de origem portuguesa, não relacionados e uma amostra de 52 indivíduos, não relacionados, oriundos de Cabo Verde, encontrando-se, ambas as populações, em Equilíbrio de Hardy-Weinberg, excepto para o locus D18S51, na população portuguesa e o locus D2S1338 na população de origem africana. Em relação aos parâmetros estatísticos forenses, este estudo demonstrou que o poder de discriminação varia entre 0,903 e 0,959, para a população portuguesa, e entre 0,908 e 0,958, para a população de Cabo Verde. Após o estudo populacional, foram analisados 39 casos forenses, devidamente anonimizados, da casuística do Serviço de Genética e Biologia Forense da Delegação de Lisboa do INML, com diferentes tipos de vestígios biológicos, como sangue, ossos, pulmão, coração, tecidos embrionários, tecidos inclusos em parafina, fígado, rim e dentes, de modo a ilustrar a utilidade desta nova metodologia nos casos forenses. No estudo de amostras degradadas, o uso da metodologia de rotina pode,
