Partindo do objeto de estudo: a gestão do currículo para a diversidade cultural é nossa intenção compreender a forma como o discurso do multiculturalismo se encontra presente nos principais documentos definidores de uma política de escola e na postura desta e dos professores, através das decisões e práticas adotadas perante uma realidade diversificada, na presença de culturas de imigrantes. A construção do saber e a análise que fazemos da forma como o currículo é gerido, seguiram um percurso assente num quadro teórico nos campos curricular e da educação intercultural, bem como nas opções metodológicas em que o estudo assenta, e às quais recorremos para a realização da componente empírica. Nesta, analisamos a forma como as escolas-alvo de estudo e os professores respondem à presença dos alunos imigrantes através das representações dos próprios alunos, seus professores e responsáveis pelas escolas; ou seja, analisamos a forma como é gerido o currículo para a diversidade cultural. /ABSTRACT - Taking the subject under study: curricular management for cultural diversity, as our starting point, our aim is to gain an understanding of the nature of multiculturalism as portrayed in the main documents that define school policy as well as in the position taken both by the school and the teachers, in the light of the decisions and practices adopted in the presence of a culturally diverse reality, immigrant cultures. The construction of a body of knowledge and the assessment we make of how the curriculum is managed, has been based on a theoretical framework in the areas of intercultural curricula and education, as well as on the choice of methodology for the study used in carrying out the empirical component In the latter, We have analysed the way in which the schools and the teachers under study responded to the presence of immigrant pupils, seen in the descriptions given by the pupils themselves, their teachers and those responsible for the schools, that is to say, we have analysed the way in which the curriculum for cultural diversity has been managed.

O fungo Pochonia chlamydospoia é um potencial agente de controlo biológico dos nemátodes-das-galhas-radiculares. Com este trabalho, pretendeu-se avaliar a eficácia de inoculações de clamidósporos no solo, no estabelecimento de uma população do fungo no solo e na raiz de tomateiro em estufa com níveis de densidade iguais ou superiores aos considerados como necessários para um eficaz controlo dos nematodes-das-galhas-radiculares. Ao longo de dois anos de ensaio, fórum efetuadas inoculações do isolado PcMR e avaliada a densidade de fungo no solo e na raiz, As inoculações efetuadas permitiram estabelecer uma população de P. chlamydosporia no solo e atingir os valores de densidade pretendidos. No entanto, os valores pretendidos para colonização da raiz pelo fungo foram atingidos apenas no primeiro ano. Foi igualmente demonstrada a capacidade do fungo em se manter no solo durante longos períodos de tempo mesmo na ausência de cultura e em condições adversas de humidade e temperatura. /ABSTRACT: Pochonia chlamydosporia is a potential root-knot nematode biological control agent. The aim of this work was to evaluate the effectiveness of chlamydospore inoculations at the soil, for the establishment at both soil and greenhouse tomato root, of a fungus population in density levels equal or superior to those considered as needed for an effective control of root-knot nematode. Along two years, several inoculations using the Portuguese isolate PcMR were made and the density of fungus at the soil and roots studied. These inoculations allowed the establishment of a population of P. chlamydosporia at the soil and achieve the desired density values. However, only in the first year of assay, the desired values of root colonization by fungus were achieved. lt was also demonstrated that P. chlamydosporia can survive for itself at the soil for a long period of time even in the absence of plant culture and in adverse moist and temperature conditions.

O presente estudo determina e analisa a importância relativa de diversos descritores ambientais, de pastoreio e de influência humana directa na distribuição da geneta (Genetta genetta L., 1758). O estudo decorreu em Monfurado, Sítio de Importância Comunitária, no Sul de Portugal. A área de estudo é predominantemente agrícola, maioritariamente ocupada por montado. A análise do padrão de distribuição deste carnívoro através de partição da variância e de ITMC (lnformation Theoretic Model Comparison) teve como objectivo orientar as prioridades na gestão das actividades humanas, compatíveis com a presença da espécie. Os resultados mostram que a distribuição da geneta é maioritariamente influenciada pelos descritores ambientais, apresentando uma relação positiva com densidade de montado com matos, conteúdo de matéria orgânica do solo e índice de Shannon de diversidade vertical da vegetação. A sua presença parece também ser promovida por níveis intermédios de pastoreio e fora das zonas de caça do regime cinegético especial. ABSTRACT; This study determines and analyses the relative importance of several environmental, livestock and human descriptors in the distribution of the common genet (Genetta genetta L., 1758). The study was conducted in Monfurado, a Site of Communitary lmportance, in South Portugal. The study area is Mediterranean farmland and is dominated by evergreen oak tree stands, named "montado". Modeling the distribution of this carnivore species was evaluated on the basis of ITMC (lnformation Theoretic Model Comparison) and variation partitioning techniques aiming to define human management activities compatible with the species conservation. The results show that the species distribution is mainly influenced by the environmental descriptors, and is positively related with montado and shrubs density, soil organic matter and Shannon's index of vertical vegetation diversity. Genet presence is favoured by intermediate levels of grazing and outside of game estates areas.

A presente dissertação teve como linha de rumo a questão de partida: De que forma é que a existência de ambientes de aprendizagem não formal e informal no território/comunidade pode enquadrar e reforçar as aprendizagens formais e a relação com a escola? Através duma abordagem teórica que inclui uma revisão bibliográfica e a análise de normativos legais que abordam e regulamentam a área em que decorre o nosso estudo, procurámos dar resposta aos seguintes objectivos: a) efectuar a cartografia institucional do território educativo do Agrupamento de Escolas nº4 de Évora; b) conhecer o potencial educativo existente nas associações e instituições localizadas no território; c) identificar instituições que possibilitem novas ofertas educativas e possam promover e potenciar o sucesso educativo, d) avaliar a oferta local de ambientes de aprendizagem e a sua disponibilidade para a promoção de parcerias educativas. Ao nível do estudo empírico e como forma de dar resposta às questões da investigação, optámos por uma metodologia mista (quantitativa/qualitativa), numa aproximação conceptual ao estudo de caso, tendo recorrido ao inquérito por questionário, aplicado como técnica de recolha de dados. Após a apresentação dos dados disponíveis, sua análise e interpretação, apurámos as seguintes conclusões: a) as instituições objecto do nosso estudo constituem um recurso do qual este Agrupamento não pode prescindir para a prossecução da sua acção educativa; b) estas instituições desenvolvem no seu seio uma considerável quantidade de actividades que envolvem aprendizagens; c) estas instituições estão receptivas à promoção de parcerias com o Agrupamento; d) estas instituições, pela área de actividade desenvolvida e pelo desenvolvimento de actividades com aprendizagem, podem potenciar novas ofertas educativas; e) estão reunidas as condições, nesta comunidade educativa, para a construção duma Carta Educativa de Agrupamento envolvendo todos os ambientes de aprendizagem disponíveis. No final da nossa dissertação expressámos as recomendações e sugestões que possam potenciar futuras investigações ABSTRACT; The following dissertation had, has a basis, the starting question (How can the existence of formal and informal environments in the territory/community regulate and reinforce the formal apprenticeships and the relationship with the school?). Through a theoretical approach and bibliographical and an analysis of legislation concerning to the area of our study we have tried to answer to the following objectives: a) create an institutional map of the educative territory of 4th Group of Schools of Évora) understand the educational potential of the institutions and associations in the territory; c) identify the institutions that may offer new educational offers that promote and may increase the educational success and d) evaluate the local offer of apprenticeship environments and their willingness to promote educational partnerships. ln terms of empirical study and as a way to answer the questions of our investigation we have opted to use a mixed quantitative/qualitative methodology in a conceptual approach to the case study having used a survey by questionnaire which was used as a technique for data collection. After the presentation of the available data, we have analyzed and interpreted it and got to the following conclusions: a) the institutions that we have studied are a resource that our Group of Schools must use to fulfill its educational action; b) these institutions create inside themselves a considerable amount of activities that involve apprenticeships; c) these institutions are receptive to the creation of partnerships with the group; d) these institutions may create new educational offers because of their activity area and their development of apprenticeship activities; e) there are conditions, in this educational community for the creation of a real Educational Chart for the 4th Group of Schools concerning all the learning environments. At the end of our dissertation we express our recommendations and suggestions that may help in future investigations

The nature of the Portuguese transition to democracy and the following state crises (1974-1975) created a ‘window of opportunity’ in which the ‘reaction to the past’ was much stronger than in the other Southern or even of Central and Eastern European transitions. In Portugal, initiatives of symbolic rupture with the past began soon after the April 25, 1974, coup d’état and transitional justice policies assumed mainly three formulas. First, the institutional reforms directed primarily to abusive state institutions such as the political police (PIDE-DGS) and political courts (Plenary courts) in order to dismantle the repressive apparatus and prevent further human rights abuses and impunity. Secondly, the criminal prosecutions addressed to perpetrators considered as being the most responsible for repression and abuses. Finally, lustration or political purges (saneamentos, the term used in Portugal to designate political purges) which were, in fact, the most common form of political justice in Portuguese transition to democracy. This paper deals with the peculiarities of transitional justice in Portugal devoting a particular attention to the judicial, a key sector to understand the way the Portuguese dealt with their authoritarian past.

Presently, conditions ensuring the validity of bootstrap methods for the sample mean of (possibly heterogeneous) near epoch dependent (NED) functions of mixing processes are unknown. Here we establish the validity of the bootstrap in this context, extending the applicability of bootstrap methods to a class of processes broadly relevant for applications in economics and finance. Our results apply to two block bootstrap methods: the moving blocks bootstrap of Künsch ( 989) and Liu and Singh ( 992), and the stationary bootstrap of Politis and Romano ( 994). In particular, the consistency of the bootstrap variance estimator for the sample mean is shown to be robust against heteroskedasticity and dependence of unknown form. The first order asymptotic validity of the bootstrap approximation to the actual distribution of the sample mean is also established in this heterogeneous NED context.

Introduction: L’asthme relié au travail (ART) est induit ou aggravé par le milieu du travail. L’asthme professionnel (AP) et l’asthme exacerbé au travail (AET) sont difficiles à distinguer en pratique clinique puisque dans les deux conditions les travailleurs se plaignent d’une détérioration de leur asthme au travail. De plus, les médecins sont souvent confrontés à des patients ayant des symptômes respiratoires reliés au travail (SRT) sans être asthmatiques. Ces patients sont souvent exclus des études qui visent à mieux caractériser l’ART. Objectifs : 1. Comparer la variabilité quotidienne des débits expiratoires de pointe (DEP) durant les périodes au et hors travail chez des sujets atteints d’AP et d’AET. 2. Évaluer la prévalence des patients ayant des SRT parmi les sujets référés pour possibilité d’ART, et comparer leurs caractéristiques et leur environnement professionnel avec ceux ayant l’ART. Résultats : L’exposition professionnelle induit une variabilité accrue des DEP chez les sujets avec AP et AET mais celle-ci est plus prononcée dans l’AP. Les sujets ayant des SRT sans être asthmatiques représentent une grande proportion des sujets référés pour possibilité d’ART. Conclusions : L’ART devrait être considéré chez tous les individus qui présentent un asthme de novo, ou une aggravation de leur asthme. La similitude des symptômes entre les sujets ayant des SRT et l’ART rend nécessaire d’effectuer une évaluation extensive. Cette évaluation devrait se faire selon une approche par étapes dans laquelle des tests objectifs améliorent la certitude du diagnostic et aident à différencier entre l’AP et l’AET.

La prévalence de l’excès de poids (EP) est en pleine croissance à travers le monde. Au Canada, elle serait de 59,1% dans la population générale, dont 23,1% d’obésité et 36,0% d’embonpoint. Ces pourcentages sont encore plus élevés dans la population autochtone, en plus d’une forte prévalence d’insécurité alimentaire (IA) et une alimentation en transition vers de moins en moins de nourritures traditionnelles, et de plus en plus de nourritures commerciales de faible densité nutritionnelle. L’Organisation mondiale de la santé (OMS) recommande des initiatives pour documenter le statut sanitaire de cette population afin d’orienter les actions pouvant prévenir les conséquences négatives sur la santé. Notre étude visait donc à décrire les phénomènes de l’EP et de l’IA chez les Premières Nations (PN) adultes de 19 ans et plus, vivant sur les réserves en Colombie-Britannique (CB). Cet échantillon est en effet le premier d’un projet de 10 ans dénommé « First Nations Food, Nutrition and Environment Study » ou (FNFNES), visant à documenter l’état nutritionnel et l’exposition à certains contaminants chez les PN vivant au sud du 60ème parallèle au Canada. Plus particulièrement, cette thèse cherche à associer trois dimensions de la santé, soit l’EP, la qualité de l’alimentation (QA) et l’IA. Nous avons voulu en effet vérifier dans le contexte des PN de la CB: 1) si une QA inadéquate serait associée à un risque plus élevé d’EP; 2) si l’IA des ménages serait associée à une qualité inadéquate de l’alimentation; et 3) si la QA et l’IA expliqueraient ensemble la présence d’EP. A l’issue des analyses (univariées, bivariées, MANOVA et régressions logistiques) de nos données transversales colligées en 2008/2009, les prévalences respectives chez les femmes (n = 493) et les hommes (n = 356) adultes étaient de 44,8% et 35,4% pour l’obésité, de 31,6% et 41,3% pour l’embonpoint, soit un total de 76,4% et 76,7% d’EP. Elles étaient de 39,3% et de 34,8% pour l’IA. Seuls 42,4% des femmes et 43,8% des hommes avaient un accès suffisant aux aliments traditionnels. Après ajustement pour les variables sociodémographiques et du mode de vie, les résultats des analyses multivariées ont montré ii que bien que les prévalences d’EP et d’IA soient assez similaires dans les deux sexes, les processus reliant l’EP, la QA et l’IA seraient différents. En effet, chez les femmes, l’EP serait expliqué par une QA compromise par des apports énergétiques relativement élevés (RC = 2,26; IC: 1,13 - 4,52), la consommation fréquente des boissons gazeuses (pour l’embonpoint, RC = 2,70; IC: 1,11 - 6,56 et pour l’obésité, RC = 2,53; IC: 1,05 - 6,09), en synergie avec l’inactivité physique (RC = 0,52; IC: 0,28 – 0,98 pour le groupe à activité modérée, et RC = 0,36; IC: 0,18 – 0,72 pour le groupe le plus actif), tandis que les produits céréaliers (RC = 0,35; IC: 0,16 - 0,75) et le lait et substituts (RC = 0,40; IC: 0,16 - 0,95) joueraient un rôle protecteur contre l’EP. D’autre part, l’IA des ménages influencerait la QA (à travers les gras saturés, p = 0,02) mais lorsque les trois variables sont étudiées ensemble, seules des dimensions de la QA apparaissent associées à l’EP. Par contre chez les hommes, le seul facteur alimentaire associé à l’EP est le pain blanc mais dans un rôle protecteur (pour l’embonpoint, RC = 0,38; IC: 0,18 - 0,76 et pour l’obésité, RC = 0,36; IC: 0,16 - 0,80); de même, lorsque les trois variables sont étudiées ensemble, l’IA joue un rôle protecteur de l’EP, dans un contexte de tabagisme relativement élevé et également protecteur, ce qui n’expliquerait pas la forte prévalence d’EP observée chez les hommes PN vivant sur les réserves de la CB. Des études plus approfondies et sur des échantillons plus grands seraient nécessaires pour mieux cerner la nature des relations mais d’ores et déjà, notre travail suggère que des effets positifs sur l’EP peuvent être attendus des politiques et programmes visant à réduire la consommation des boissons gazeuses et l’inactivité physique, et à encourager la consommation des produits céréaliers et de lait et substituts chez les femmes. Quant aux hommes, les conclusions de notre étude ne nous permettent pas encore de formuler des recommandations précises. Alors, les comportements santé recommandés aux femmes devraient être généralisés aux hommes en attendant les conclusions d’autres études.
