Reflections on Young Women and the Youth Crisis in Sub-Saharan Africa

There has been an upsurge in academic studies on youth in Sub-Saharan Africa since the last decade of the 20th century, underlining the growing importance that generational cleavages seem to play in today’s societies. However, gender has been neglected in research and policies bearing on youth, unveiling a rather negative and limited approach to Sub-Saharan African youth: limit situations are those most focused on (as the role of youth in conflicts), young males being perceived as the most active in those contexts and who therefore shall be the focus of political (and academic) attention. Acknowledging the need to integrate gender in the approaches to youth, this paper tries to grasp, through a preliminary literature review, how the predicaments of the so-called “youth crisis” are lived and perceived by young girls, and identify the main themes and theoretical perspectives of the literature that has tried to explore this thematic.

Analysis of malaria associated genetic traits in Cabo Verde, a melting pot of European and sub Saharan settlers

Malaria has occurred in the Cabo Verde archipelago with epidemic characteristics since its colonization. Nowadays, it occurs in Santiago Island alone and though prophylaxis is not recommended by the World Health Organization, studies have highlight the prospect of malaria becoming a serious public health problem as a result of the presence of antimalarial drug resistance associated with mutations in the parasite populations and underscore the need for tighter surveillance. Despite the presumptive weak immune status of the population, severe symptoms of malaria are not observed and many people present a subclinical course of the disease. No data on the prevalence of sicklecell trait and red cell glucose-6-phosphate dehydrogenase deficiency (two classical genetic factors associated with resistance to severe malaria) were available for the Cabo Verde archipelago and, therefore, we studied the low morbidity from malaria in relation to the particular genetic characteristics of the human host population. We also included the analysis of the pyruvate kinase deficiency associated gene, reported as putatively associated with resistance to the disease. Allelic frequencies of the polymorphisms examined are closer to European than to African populations and no malaria selection signatures were found. No association was found between the analyzed human factors and infection but one result is of high interest: a linkage disequilibrium test revealed an association of distant loci in the PKLR gene and adjacent regions, only in non-infected individuals. This could mean a more conserved gene region selected in association to protection against the infection and/or the disease.

Gangues, Novíssimas Guerras e (Sub)Cultura da Violência/Delinquência

This paper aims to reflect the problem of gangs and their relationship with urban space in the urban wars scenery that emerged in the 1980s and 1990s in densely populated cities, as well as discuss the adequacy of explanations on the phenomenon of violence and delinquency, in some contexts, from the concept of subculture. Starts with the conceptualization and characterization of gangs, presenting them as one of the central figures in the new type of violent conflict that erupts in the urban centers around the world and relate their institutionalization in neighbourhood with the idea of ‘Retreat of the State’ in poorest urban zones, as well as presenting the position of some families in relation to their activities.

Familias Estruturadas e Sub-Familias de Matrizes

Desenvolvemos modelos para matrizes estocásticas simétricas com matriz média com característica um. Estas matrizes desempenham um papel relevante em muitas situações interessantes, por exemplo em problemas de componentes principais com primeira componente dominante. Mostramos como ajustar e validar tais modelos e como medir o respectivo grau de Ajustamento através de um estudo de simulações para evidenciar o bom comportamento dos estimadores obtidos. Esse bom comportamento verifica-se quando o primeiro valor próprio da matriz média e suficientemente preponderante. Utilizando a linearidade assimptótica foi possível testar se esta condição se verifica. Al em de modelos para matrizes quase escalares estudamos famílias estruturadas de modelos, cujas matrizes correspondem aos tratamentos de um delineamento base. Consideramos ainda famílias de modelos divididas em subfamílias que correspondem a esses tratamentos. Estamos sobretudo interessados em modelos base com estrutura ortogonal. Apresentamos essa estrutura e mostramos como aplicar esses modelos no estudo de famílias estruturadas. Damos uma aplicação dos nossos resultados a metodologia Statis, concretamente aos resultados de eleições autárquicas em Portugal Continental. Nesta aplicação utilizamos o facto destes modelos serem aplicáveis a primeira e segunda etapas desta metodologia. Assim, consideramos um par de famílias decompostas, em subfamílias que correspondem aos tratamentos do mesmo delineamento base. A primeira família corresponde a primeira etapa da metodologia Statis, e a segunda família corresponde a segunda etapa da mesma metodologia. Estudamos a heterogeneidade das subfamílias de ambas as famílias de modelos. Concluímos que a ordenação das subfamílias a partir da respectiva heterogeneidade se mantém da primeira para a segunda etapa.

Développement des filières agricoles et promotion des marchés

Le Gouvernement Capverdien avec l´assistance de la FAO à élaborer une stratégie de développement du secteur agricole au sens large, à long terme (horizon 2015) ainsi qu‟un Plan d‟action correspondant pour le moyen terme. Dans le cadre de l´initiative de la CEDEAO, Cap Vert c´est lance dans l‟élaboration de la présente sub-composante que s‟inscrit dans le cadre de l‟appui à la Formulation et mise en oeuvre d‟un Programme National d‟ Investissement Agricole (PNIA) pour la mise en oeuvre du PDDAA/NEPAD. Le document de stratégie de réduction de la pauvreté (DECRP) du pays indique la sécurité alimentaire et la garantie de la cohésion sociale en milieu rural comme les axes stratégiques centraux et dans le cadre des stratégies nationales de lutte contre la pauvreté et de sécurité alimentaire, le gouvernement du Cap-Vert a adoptée et mis en oeuvre un certain nombre de programmes pour lever les contraintes multiples auxquelles le pays est confronté, et relancer le secteur agricole. La vision stratégique de développement à court et moyen termes du Gouvernement est présentée dans le document intitulé „Grandes Options du Plan‟, basés sur les orientations suivantes: a. Promouvoir la bonne gouvernance comme facteur de développement, en réformant l‟Etat, en intensifiant la démocratie et en renforçant la citoyenneté, b. Promouvoir la capacité entrepreneur, la compétitivité et la croissance ; élargir la base productive, c. Développer le capital humain et orienter le système d‟enseignement/ formation vers les domaines prioritaires de développement, d. Promouvoir une politique globale de développement social, luttant contre la pauvreté et renforçant la cohésion et la solidarité, e. Développer des infrastructures de base et économiques et promouvoir l‟aménagement du territoire pour un développement équilibré. Étant un secteur important de l‟activité économique et sociale du Cap-Vert, l‟agriculture doit jouer les rôles fondamentaux ci-après: améliorer les conditions d‟existence durable des ruraux par la promotion d‟une approche intégrée du développement des communautés rurales, en misant sur le développement agrosylvo-pastoral comme axe fondamental,  renforcer la sécurité alimentaire des populations rurales et urbaines, l‟approvisionnement du marché interne et le développement du secteur touristique en plein essor. Le gouvernement préconise la modernisation de l‟agriculture, la déconcentration des services et institutions d‟appui a la production, la promotion de la compétitivité dans l‟agriculture et la pêche, notamment par l‟élargissement et la diversification de la base productive. La modernisation du secteur agricole et le développement rural par l‟introduction de nouvelles technologies pour l‟intensification et la diversification, doivent assurer le renforcement du tissu économique rural. A cet effet, la croissance durable de la production agricole dépend prioritairement de mesures de rationalisation et d‟optimalisation de l‟utilisation de l‟eau d‟irrigation. Les orientations devront privilégier le montage de mécanismes d‟investissements dirigés vers une nouvelle agriculture spécialisée, complétée par la formation agro-alimentaire, et le développement d‟autres secteurs stratégiques et, particulièrement le tourisme. Les orientations stratégiques pour le secteur agricole, sont identifiées comme suit :  la réorganisation de la production pluviale (végétale et animale) en vue de renforcer la capacité productive et la protection de ces zones,  la diversification des activités de production et la prestation des services en milieu rural, élargissant ainsi la base productive, en accord avec les grandes orientations du Plan Stratégique,  le développement et la valorisation de l‟écotourisme.

Estudo sobre o grau de imperfeição em sub-reticulados do reticulado inteiro

Um dos grandes problemas em aberto na matemática até os dias de hoje é a questão do empacotamento esférico. Para tentar resolver este problema, tem-se estudado alguns fatores importantes inerentes a isso. Nesse trabalho apresentamos uma breve introdução à teoria de reticulados e teoria de códigos, onde trataremos conceitos como densidade de empacotamento e de cobertura. O objetivo deste trabalho é o estudo da densidade de empacotamento e de cobertura em reticulados relativos à norma p. Neste estudo enfatizaremos o artigo Quasi-perfect codes in the lp metric de Strapasson et al. [13] onde é estabelecida a noção de perfeição e imperfeição de reticulados relativos à norma p, e é apresentado um algoritmo que busca por reticulados perfeitos e quase-perfeitos.
