O papel dos quintais urbanos na segurança alimentar, bem estar e conservação da biodiversidade

Residential homegardens have environmental and social roles in the urban environment. These green spaces can potentially minimize the impacts caused by the growth of cities, being an alternative to connect fragmented areas or offer refuge to wildlife and therefore support the conservation of biodiversity. In addition, the homegardens demonstrate a leading role in increasing human well-being by promoting socialization opportunities, contact with nature, local culture as well as improvements in food security for the urban families. Nevertheless, it is still unclear what specific characteristics of homegardens can act effectively in the conservation of the biodiversity, as well as in the construction of food security and well being of the homegardeners and their families. The first chapter of this thesis analyzed the diversity of plant species (native and exotic) and assessed the contribution of different types of urban gardens (ornamental and forest gardens alike) in the presence of wildlife such as birds, monkeys and lizards. In the second chapter we evaluated the contribution of those gardens to the welfare and food security of their owners. In order to do this, 41 gardens were visited in Pium, a southern coastal town in the northeastern Brazil, which also happens to be in a periurban region undergoing rapid urban expansion and pressure from the real estate market. We surveyed the planned biodiversity and fauna associated with homegardens. The data related to food security and welfare were sampled through interviews with the person in charge of taking care of the gardens. These interviews covered issues on the supply of food from the garden and absence of chemical products, as well as aspects of the GNH indicator (Gross National Happiness). The results showed that these homegardens generally contribute little to the maintenance of native plant species (native species = 29/ total = 187). From its main features, the gardens were classified as ornamental, forest gardens and forest farms. These groups had a different effect on the presence of the animals studied and the last two contained most of the sampled native species. The diversity of plants and trees was a good predictor of the presence of birds and monkeys. Thus, the contribution of yards for the conservation of biodiversity depends on the type of garden: some even can have negative effects on conservation. These results can direct new approaches to detailed understanding of gardens and also of public policies applied to urban planning. The results of the second chapter showed that the two types of forest gardens contributed to household food security, for providing food and medicinal herbs, which mostly did not have pesticides and chemical 12 fertilizers. But the three groups of gardens are important components for the well being of their stakeholders. Gardens help promote the transmission of knowledge on agriculture, socialization, contact with nature and bring up feelings related to peace and harmony. Thus, forest gardens can be considered important means to get through public projects and policies designed to encourage biodiversity and promote food security and well-being in urban areas

Fatores de virulência, resistência ao estresse osmótico e susceptibilidade de isolados de Candida tropicalis oriundos de ambiente costeiro do nordeste brasileiro

Several studies have been developed regarding health risks associated with the recreational use of beaches contaminated with domestic sewage. These wastes contain various microorganisms, including Candida tropicalis, etiologic agent of both superficial infections such as systemic, as well as indicator of fecal contamination for the environment. In this context, the objective of this study was to characterize C. tropicalis isolates from the sandy beach of Ponta Negra, Natal, Rio Grande do Norte, Brazil, regarding the expression of in vitro virulence factors, adaptation to osmotic stress and susceptibility to antifungal drugs. We analyzed 62 environmental isolates of C. tropicalis and observed a great variation between them for the various virulence factors evaluated. In general, environmental isolates were more adherent to CEBH than C. tropicalis ATCC13803 reference strain, besides the fact they were also highly biofilm producers. In relation to morphogenesis, most isolates presented wrinkled phenotype in Spider medium (34 isolates, 54.8 %). When assessing enzyme activity, most isolates had higher proteinase production than C. tropicalis ATCC13803 reference strain. In addition, 35 isolates (56.4 %) had high hemolytic activity (hemolysis index > 55). With regard to C. tropicalis resistance to osmotic stress, 85.4% of the isolates were able to grow in a liquid medium containing 15% sodium chloride, corroborating to high survival capacity described for this yeast at marine environment. Finally, with regard to sensitivity to antifungal drugs, it was observed high resistance to the azoles tested, with the occurrence of the "Low-high" phenomenon and similar effect to the paradoxical growth which occurs to the echinocandins. For the three azoles tested we verified that 15 strains were resistant (24.2 %). Some strains were also resistant to amphotericin B (14 isolates, 22.6 %), while all of them were sensitive for the echinocandins tested. Therefore, our results demonstrate that C. tropicalis isolated from the sand of northeast of Brazil can fully express virulence attributes and showed a high persistence capacity on the coastal environment, in addition of being significantly resistant to most applied antifungals in current clinical practice. This constitutes a potential health risk to visitors of this environment, especially immunocompromised individuals and those with extreme age range.

Questionamentos acerca de valores axiológicos no turismo: uma abordagem fenomenológica hermenêutica

The study presents the possibility of interpretation of axiological values of tourism as a practice conceived on a human being or Dasein as being-in-the-world of tourism. The value, as an object of Axiology, was considered the predictor of the human being conduct in the phenomenon reflecting this same value in tourism. The aim was to comprehend and interpret through the way of being of Dasein in tourism, which axiological values are chosen to the practice of tourism and the intentional feelings directed to these values. A phenomenological hermeneutics research with exploratory characteristics was accomplished in order to survey the values. Ten episodic interviews were conducted from the hermeneutic situation - constituted by fore-having, fore-sight and fore-conception of each Dasein interviewed, by adopting a sympathetic conduct and sympathy of Max Scheler and the use of emotional intuition to capture the intentional feelings, interpreted afterwards by the analysis of a Martin Heidegger's phenomenology in Being and Time. The results showed that, even without categorisation, the totality of the living experiences, the way of being of positive values outnumber the negatives ones in the existence of each Dasein, leading them to the Learning, which are comprising: experiences to provide self-knowledge, historical-cultural values, and memory as part of the learning experiences, hospitality as a way of openness and socio-cultural exchange, solidarity and peace. Intentional feelings directed at the values for the choice for practicing tourism were: love, happiness, pleasure, respect and trust. Four evidences were found concerning the use of sentimental perspective and intentional feeling of Scheler and regarding the logic of the heart of Pascal used by this author. The sociocultural interrelationships and exchanges form the basis for developing tourism as phenomenon. Therefore the character being-with or Mitsein is prevalent in tourism activities. Despite the learning was the purpose of the experiences, the ultimate goal was the improvement and personal enrichment of Dasein´s humanity development. The study also showed the hermeneutic phenomenological seeing opens the access of the living experiences of values, without making arbitrarily judgment and achieve "to the thing themselves", which, by the overlapping of categories, dispositions and intentional feelings, form the evaluative experiences and are possible to access through the fundamental ontology of Heidegger. The study contributes to broaden the vision concerning to the totality of tourism and the practitioners Dasein of it. As possibilities for deepening studies, was pointed out: the total person of Scheler; the care or Sorge as a form of love in Heidegger; happiness and pleasure in the practice of tourism and human flourishing or eudaimonia.

Cidades saudáveis e qualidade de vida em Uberlândia (MG): aportes metodológicos para um processo em construção

The current study includes theoretical and methodological reflections on the quality of life in the city of Uberlândia, Minas Gerais. It started from the thought that the quality of life is multifactorial and is permanently under construction and the main objective of analyzing it as one of the componets of Healthy Cities's moviment. The theoretical research focused on the concepts of healthy cities, quality of life, health, sustainability, well-being, happiness, indexes and indicators. From the use of multiple search strategies, documentary and on field of quantitative and qualitative character, this research of exploratory descriptive nature can offers a contribution to the studies on the quality of life in cities. It is proposed that the studies startes to work with some concept, like some notions os life quality adequated for some paticular reality, whose notions can approach concepts already established as health. This step is important on the exploratory researches. The studies may include aspects of objective analysis, subjective or both. The objective dimension, which is most common approach, are traditionally considered variables and indicators related to: the urban infrastructure (health, education, leisure, security, mobility), dwelling (quantitative and qualitative dwlling deficit), the urban structure (density and mix uses), socioeconomic characteristics (age, income, education), urban infrastructure (sanitation, communication), governance (social mobilization and participation). To focus on the subjective dimension, most recent and unusual, it is proposed to consider the (dis)satisfaction, the personal assessment in relation to the objective aspects. In conclusion, being intrinsically related to the health, the quality of life also has a number of determinants, and the ideal of the reach of quality of life depends on the action of all citizens based on the recognition of networks and territories, in a interescalar perspective and intersectoral. Therefore, emphasis in given on the potential of tools, such as the observatories, to monitor and intervent in reality, aiming in a building process of healthy cities.

Contradições como força de mudança: o processo de formação continuada de professores do ensino médio enquanto potencializador da práxis transformadora à luz da teoria histórico-cultural

The intervention research proposed was based on the Cultural-Historical Theory based on the laws and logic of materialism historical-dialectical. Therefore, we tried to design a research process that involved all as responsible for the process. In the field of continuous teacher's training usually has been found dualistic relationship / paradoxical processes as a result of the adopted training models which are characterized by individualist human processes. The teacher training work sought to overcome this dualism, to promote the unveiling of the contradictions with regard to teaching models. As a hypothesis, we imagined that immersed in this process, teachers recognize such contradictions, and this recognition would make the contradictions become the driving force of change in teaching practice, realizing the teaching-learning-development triad as the basis of praxis. Aiming to develop a process of continuing education to bring results to the professional teachers development looking for answer the following research question: How and what the changes of teachers who participated in the Didactic-Formative Intervention process raised the quality of their teaching practices? In this context, the objective of the research was to develop a process of Didactic-Formative Intervention from the perspective of Cultural-Historical Theory with high school teachers in order to theorize about the changes in pedagogical practices of teachers and learn aspects that transform the essence teaching practice. The research involved two high school teachers of a public school in Uberlândia-MG. The training meetings took place at the school through a collective study group between the years 2013 and 2015. As procedures were used two interconnected aspects: classes observations, and a theoretical and methodological training, both for diagnosis and for the process evaluation, the second aspect has a formative dimension, and a didactic dimension (double meaning) to form didactically the teacher and to elaborate didactic procedures. The collected data were analyzed by observing the assumptions of the method, analysis by units and the processuality. As results teachers showed changes in their teaching practices regarding the organization of the pedagogical work and also centered their design educational actions based on learning and development of the students. The presence of continuous diagnosis during the classes, work with a systems of concepts and their conceptual links, problematization as a teaching method can be pointed as meaningful changes in their praxis. Regarding the training activities that emerged from the analysis of the compiled materials and analyzed throughout the process can be emphasized: forming a collective group of school teachers continuous training, diagnostics, development of practical activities, increase relationships among participants, the choice of scientific material used should have direct relation to the needs of the participants, promoting conditions that enable the emergence of contradictions between the pedagogical practice of teachers and teaching based on the perspective of the Cultural-Historical Theory. This research craved to develop and design a teachers' training processes that increase the quality of teachers life and ways of teaching in the Brazilian public school.

Plus ça change...Le renouvellement de la tradition chez Régine Robin, Dany Laferrière et Ying Chen

Cette thèse analyse la manifestation de la tradition dans certains textes des écrivains migrants au Québec, nommément La Québécoite et L’Immense fatigue des pierres de Régine Robin, Comment faire l’amour avec un nègre sans se fatiguer, Cette grenade dans la main du jeune nègre est-elle une arme ou un fruit ?, Pays sans chapeau et L’Énigme du retour de Dany Laferrière et, enfin L’Ingratitude et Immobile de Ying Chen. Les références à des récits, à des croyances et à des pratiques collectives qui se trouvent dans ces textes signalent une transformation de la transmission de l’héritage culturel d’une génération à l’autre. Afin de parvenir à une meilleure compréhension des liens entre la mémoire collective et la communauté culturelle se définissant dans le présent, je me sers du travail de folkloristes comme Alan Dundes, Simon Bronner et Richard Handler de même que des théories sur la faculté de la tradition proposées par Paul Ricœur, Walter Benjamin et Pierre Nora. Dans la première partie de la thèse, j’étudie l’imaginaire populaire du XIXe siècle et son incorporation dans la littérature canadienne-française de l’époque. Ensuite, j’analyse la remise en question de la tradition – de même que le rôle sous-jacent qu’elle continue de jouer, lors de la Révolution tranquille. Par rapport à ces deux périodes précédentes, l’usage du folklore chez les auteurs migrants laisse présager une nouvelle opération de la tradition dans un contexte où plusieurs groupes culturels se rencontrent. Dans un contexte pluraliste, l’idée de la communauté culturelle est fabriquée en fonction de notre appartenance à plusieurs groupes. Je m’intéresse à comment les gens qui habitent ensemble formulent des liens au passé même dans une situation dans laquelle ils ne partagent pas les mêmes rapports à la mémoire collective. Explorant le renouvellement, qui peut sembler paradoxal, de la tradition, je forme l’hypothèse qu’il est possible pour un groupe de se définir en fonction de valeurs culturelles puisées dans un passé collectif qui s’adaptent constamment à la réalité actuelle.

Satisfação com a Vida e com o Lar

O envelhecimento da população é uma realidade indiscutível nas sociedades contemporâneas. Independentemente dos modelos societários em que vivamos, a longevidade só faz sentido se for acompanhada por felicidade, qualidade e satisfação de vida. No entanto, este envelhecimento generalizado da população traz consigo vários constrangimentos à população idosa, entre eles a sua institucionalização em lares de terceira idade. O processo de institucionalização pode ter efeitos negativos ao nível do bemestar psicossocial dos idosos institucionalizados se não forem tidos em conta determinados factores promotores do sucesso adaptativo que conduzam a melhores níveis de satisfação. Neste estudo, a questão lançada tem subjacente a convicção de que existem vários factores que podem contribuir ou influenciar positiva ou negativamente a satisfação com o lar das pessoas idosas residentes em cenários institucionais. Este foi, precisamente, o objectivo do nosso trabalho, ou seja, analisar os níveis de satisfação com a vida e com o lar e os factores que se relacionam com a satisfação com o lar. Trata-se de um estudo de observação, transversal, que recaiu em 49 idosos institucionalizados em duas instituições da rede solidária do concelho de Miranda do Corvo. Utilizámos uma metodologia quantitativa para medir objectivamente o nível de satisfação com a vida e com o lar das pessoas idosas institucionalizadas. No âmbito da utilização desta metodologia administrou-se um inquérito por questionário, elaborado por nós, e uma Escala de Satisfação com a Vida (Meadow et. al., 1992). A aplicação desta Escala de Satisfação com a Vida revelou boas características psicométricas ao nível da fidedignidade (medida através da sua consistência interna) e a média reflecte um grupo de inquiridos moderadamente satisfeitos com a vida. Na nossa investigação empírica tivemos oportunidade de verificar que a maior parte dos inquiridos se manifestou satisfeita com a sua residência no lar. Apurámos igualmente que existe uma associação entre a satisfação com o lar e a solidão e que a satisfação difere consoante os contactos de amizade (presença versus ausência) e as actividades sóciorecreativas (participação versus não participação).

Serviço Social e Deficiência Mental: a perspectiva subjectiva da qualidade de vida

Explorar a qualidade de vida de jovens com deficiência mental permite abrir caminhos de reflexão em relação às políticas sociais, aos constrangimentos das instituições e à acção dos profissionais, nomeadamente dos Assistentes Sociais. O conceito de qualidade de vida adoptado abrange oito dimensões consideradas fundamentais: o bem-estar físico e emocional, as relações interpessoais, a inclusão social, o desenvolvimento pessoal, o bem- -estar material, a auto-determinação e os direitos. O objectivo do estudo consistiu em avaliar a qualidade de vida de jovens com deficiência mental ligeira, através da análise comparativa entre dois grupos: um vivendo em contexto familiar e outro em contexto institucional. O estudo é de natureza exploratória, sendo a amostra constituída por vinte e quatro jovens, com idades compreendidas entre os dezasseis e os vinte anos. A informação foi recolhida mediante uma entrevista estruturada, com base num questionário previamente testado. Independentemente do seu contexto de vida, estes jovens revelam uma boa percepção da sua condição física e do seu grau de autonomia e de felicidade. Estão satisfeitos com as pessoas com quem se relacionam em contexto de trabalho e atribuem níveis semelhantes de importância e satisfação relativamente ao seu salário. Os jovens que vivem em contexto familiar consideram que têm mais condições de privacidade e de conforto e que são mais independentes, confiam mais nas suas capacidades, consideram mais importante o direito à diferença, revelam-se mais críticos quanto ao local e às regras do trabalho e estão mais satisfeitos em todas as áreas previstas. Os jovens que vivem em contexto institucional têm uma percepção mais negativa das relações que estabelecem com pessoas próximas. Na globalidade, os jovens que vivem em contexto familiar têm uma percepção mais positiva da sua qualidade de vida do que os que vivem em contexto institucional. É evidente a necessidade de realização de outros estudos que permitam conhecer melhor esta realidade, pois só assim será possível encaminhar a acção dos Assistentes Sociais no sentido da construção de um futuro melhor para todos.

Estudo do Impacto da Desinstitucionalização de Doentes e /ou Deficientes Mentais no seu Bem-estar Psicológico: uma experiência de reabilitação psicossocial – “Quinta Pedagógica das Romãzeiras”

O presente estudo analisa uma experiência de desinstitucionalização de pacientes que se encontravam internadas na Casa de Saúde Rainha Santa Isabel, em Condeixa-a- Nova, visando a sua inserção socio-comunitária, através da integração num projecto, que tem por nome “Quinta Pedagógica das Romãzeiras” apoiado num programa de reabilitação psicossocial (THS – Treino de Habilidades Sociais) e de Actividades de Vida Diária (AVDs). O universo do estudo compreendeu um grupo de vinte pacientes que foram acompanhados na sua trajectória de desinstitucionalização e avaliados em dois momentos com um intervalo de oito meses. A primeira avaliação foi feita antes da desinstitucionalização de modo a obter os valores relativos ao estado psicológico e psicopatológico das utentes internadas. A segunda avaliação foi feita após a desinstitucionalização e a intervenção da equipa técnica através do respectivo projecto de reabilitação psicossocial. As duas áreas avaliadas foram: O índice Geral de Sintomas Psicopatológicos (Sintomatologia Psiquiátrica) e o nível de Bem-Estar Psicológico. Os resultados deste estudo apontam no sentido, globalmente, existirem mudanças positivas consideradas estatisticamente significativas nos índices de sintomatologia, entre os dois momentos de avaliação. No que diz respeito à área de Bem-Estar Psicológico, os resultados revelam igualmente diferenças consideradas muito significativas entre os dois momentos de avaliação. O factor que se destacou mais foi o factor da Felicidade e da Auto-estima. O factor que menos se destacou foi o da sociabilidade. Estes resultados traduzem o impacto importante do processo de desinstitucionalização no aumento do Bem-estar Psicológico das pessoas com deficiência e/ou doença mental, institucionalizadas em internamento de longo termo. Os resultados também perspectivam uma mudança na qualidade de vida assim como na redução da sintomatologia, influenciando positivamente e de forma indirecta os resultados do impacto do processo de desinstitucionalização.

Influence of frequent nightmares on REM sleep-dependent emotional memory processing

La littérature suggère que le sommeil paradoxal joue un rôle dans l'intégration associative de la mémoire émotionnelle. De plus, les rêves en sommeil paradoxal, en particulier leur nature bizarre et émotionnelle, semblent refléter cette fonction associative et émotionnelle du sommeil paradoxal. La conséquence des cauchemars fréquents sur ce processus est inconnue, bien que le réveil provoqué par un cauchemar semble interférer avec les fonctions du sommeil paradoxal. Le premier objectif de cette thèse était de reproduire conceptuellement des recherches antérieures démontrant que le sommeil paradoxal permet un accès hyper-associatif à la mémoire. L'utilisation d'une sieste diurne nous a permis d'évaluer les effets du sommeil paradoxal, comparativement au sommeil lent et à l’éveil, sur la performance des participants à une tâche sémantique mesurant « associational breadth » (AB). Les résultats ont montré que seuls les sujets réveillés en sommeil paradoxal ont répondu avec des associations atypiques, ce qui suggère que le sommeil paradoxal est spécifique dans sa capacité à intégrer les traces de la mémoire émotionnelle (article 1). En outre, les rapports de rêve en sommeil paradoxal étaient plus bizarres que ceux en sommeil lent, et plus intenses émotionnellement ; ces attributs semblent refléter la nature associative et émotionnelle du sommeil paradoxal (article 2). Le deuxième objectif de la thèse était de préciser si et comment le traitement de la mémoire émotionnelle en sommeil paradoxal est altéré dans le Trouble de cauchemars fréquents (NM). En utilisant le même protocole, nos résultats ont montré que les participants NM avaient des résultats plus élevés avant une sieste, ce qui correspond aux observations antérieures voulant que les personnes souffrant de cauchemars soient plus créatives. Après le sommeil paradoxal, les deux groupes, NM et CTL, ont montré des changements similaires dans leur accès associatif, avec des résultats AB-négatif plus bas et AB-positif plus grands. Une semaine plus tard, seul les participants NM a maintenu ce changement dans leur réseau sémantique (article 3). Ces résultats suggèrent qu’au fil du temps, les cauchemars peuvent interférer avec l'intégration de la mémoire émotionnelle pendant le sommeil paradoxal. En ce qui concerne l'imagerie, les participants NM avaient plus de bizarrerie et plus d’émotion positive, mais pas négative, dans leurs rêveries (article 4). Ces attributs intensifiés suggèrent à nouveau que les participants NM sont plus imaginatifs et créatifs à l’éveil. Dans l'ensemble, les résultats confirment le rôle du sommeil paradoxal dans l'intégration associative de la mémoire émotionnelle. Cependant, nos résultats concernant le Trouble de cauchemars ne sont pas entièrement en accord avec les théories suggérant que les cauchemars sont dysfonctionnels. Le groupe NM a montré plus d’associativité émotionnelle, de même que plus d'imagerie positive et bizarre à l’éveil. Nous proposons donc une nouvelle théorie de sensibilité environnementale associée au Trouble de cauchemar, suggérant qu'une sensibilité accrue à une gamme de contextes environnementaux sous-tendrait les symptômes uniques et la richesse imaginative observés chez les personnes souffrant de cauchemars fréquents. Bien que davantage de recherches doivent être faites, il est possible que ces personnes puissent bénéficier e milieux favorables, et qu’elles puissent avoir un avantage adaptatif à l'égard de l'expression créative, ce qui est particulièrement pertinent lorsque l'on considère leur pronostic et les différents types de traitements.

Le sommeil comme marqueur du déclin cognitif dans la maladie de Parkinson

La maladie de Parkinson (MP) est une maladie neurodégénérative qui se caractérise principalement par la présence de symptômes moteurs. Cependant, d’autres symptômes, dits non moteurs, sont fréquents dans la MP et assombrissent le pronostic; ceux ci incluent notamment les désordres du sommeil et les troubles cognitifs. De fait, sur une période de plus de 10 ans, jusqu’à 90 % des patients avec la MP développeraient une démence. L’identification de marqueurs de la démence dans la MP est donc primordiale pour permettre le diagnostic précoce et favoriser le développement d’approches thérapeutiques préventives. Plusieurs études ont mis en évidence la contribution du sommeil dans les processus de plasticité cérébrale, d’apprentissage et de consolidation mnésique, notamment l’importance des ondes lentes (OL) et des fuseaux de sommeil (FS). Très peu de travaux se sont intéressés aux liens entre les modifications de la microarchitecture du sommeil et le déclin cognitif dans la MP. L’objectif de cette thèse est de déterminer, sur le plan longitudinal, si certains marqueurs électroencéphalographiques (EEG) en sommeil peuvent prédire la progression vers la démence chez des patients atteints de la MP. La première étude a évalué les caractéristiques des OL et des FS durant le sommeil lent chez les patients avec la MP selon qu’ils ont développé ou non une démence (MP démence vs MP sans démence) lors du suivi longitudinal, ainsi que chez des sujets contrôles en santé. Comparativement aux patients MP sans démence et aux sujets contrôles, les patients MP démence présentaient au temps de base une diminution de la densité, de l’amplitude et de la fréquence des FS. La diminution de l’amplitude des FS dans les régions postérieures était associée à de moins bonnes performances aux tâches visuospatiales chez les patients MP démence. Bien que l’amplitude des OL soit diminuée chez les deux groupes de patients avec la MP, celle ci n’était pas associée au statut cognitif lors du suivi. La deuxième étude a évalué les marqueurs spectraux du développement de la démence dans la MP à l’aide de l’analyse quantifiée de l’EEG en sommeil lent, en sommeil paradoxal et à l’éveil. Les patients MP démence présentaient une diminution de la puissance spectrale sigma durant le sommeil lent dans les régions pariétales comparativement aux patients MP sans démence et aux contrôles. Durant le sommeil paradoxal, l’augmentation de la puissance spectrale en delta et en thêta, de même qu’un plus grand ratio de ralentissement de l’EEG, caractérisé par un rapport plus élevé des basses fréquences sur les hautes fréquences, était associée au développement de la démence chez les patients avec la MP. D’ailleurs, dans la cohorte de patients, un plus grand ralentissement de l’EEG en sommeil paradoxal dans les régions temporo occipitales était associé à des performances cognitives moindres aux épreuves visuospatiales. Enfin, durant l’éveil, les patients MP démence présentaient au temps de base une augmentation de la puissance spectrale delta, un plus grand ratio de ralentissement de l’EEG ainsi qu’une diminution de la fréquence dominante occipitale alpha comparativement aux patients MP sans démence et aux contrôles. Cette thèse suggère que des anomalies EEG spécifiques durant le sommeil et l’éveil peuvent identifier les patients avec la MP qui vont développer une démence quelques années plus tard. L’activité des FS, ainsi que le ralentissement de l’EEG en sommeil paradoxal et à l’éveil, pourraient donc servir de marqueurs potentiels du développement de la démence dans la MP.

Validação da Versão Portuguesa da Center for Epidemiologic Studies Depression Scale for Children (CES-DC)

A Depressão na infância e adolescência, tal como na população adulta, é uma das perturbações mentais mais comuns. Uma vez que o seu aparecimento nestas faixas etárias conduz a graves consequências na idade adulta, é fundamental identificar os sintomas depressivos precocemente. Desta forma, os instrumentos de autorrelato têm um papel fundamental, uma vez que permitem com facilidade, de forma fidedigna e válida, ter acesso a formas de pensar, sentir e agir dos sujeitos. O objetivo do presente trabalho consistiu na tradução, adaptação e estudo da Center for Epidemiological Studies Depression Scale for Children (CES-DC) (Weissman, Orvash & Padian, 1980) para os adolescentes portugueses. A amostra é constituída por 417 adolescentes, com idades compreendidas entre os 12 e os 18 anos a frequentar o 3º ciclo do ensino básio e ensino secundário. Para o estudo da validade convergente e divergente da CES-DC, foram utilizados a Depression Anxiety Stress Scales (DASS 21) (Lovibond & Lovibond, 1995), o Children's Depresssion Inventory (CID) (Marujo, 1994) e a Students' Life Satisfaction Scale (SLSS) (Marques, Pais-Ribeiro & Lopez, 2007) que avaliam, respetivamente, os estados emocionais negativos (depressão, ansiedade e stress), a sintomatologia depressiva e a satisfação global com a vida. Os resultados obtidos mostram que a escala possui uma boa consistência interna, uma estabilidade temporal adequada, assim como uma boa validade. Sugerem, ainda, tratar-se de uma escala tridimensional: fator humor, fator interpessoal e fator felicidade. Estes dados permitem o avanço da Psicologia, no que diz respeito à avaliação e prática clínica com adolescentes. A utilidade do questionário deve ser verificada noutras faixas etárias, principalmente, nas de menos de 12 anos de idade, e também numa amostra clínica. Não obstante as limitações apontadas, os resultados sugerem que a CES-DC é um questionário útil na avaliação de sintomas depressivos nos adolescentes. / Depression in children and adolescents, as well as in adults, is one of the most common mental disorders. Since its appearance in these age groups leads to serious consequences in adulthood, it is critical to identify depressive symptoms in early stages. Therefore, self-report instruments play a key role in this contexto since they allow to easily, reliably and validly have access to ways the subject thinks, feels and acts. The aim of this study was to translate, adapt and study the Center for Epidemiological Studies Depression Scale for Children (CES-DC) (Weissman, Orvash & Padian, 1980) for portuguese adolescents. The sample consists of 417 adolescents, aged between 12 and 18 years old, attending the 3rd cycle of basic education and secondary education schools. To study the convergent and divergent validity of the CES-DC, the Depression Anxiety Stress Scales (DASS 21) (Lovibond & Lovibond, 1995) was used, along with the Children's depression Inventory (CDI) (Sailor, 1994) and the Students' Life Satisfaction Scale (SLSS) (Marques, Pais-Ribeiro & Lopez, 2007) that evaluate, respectively, the negative emotional states (depression, anxiety and stress), depressive symptoms and overall satisfaction with life. The results show that the evaluated scale presents a good internal consistency, an adequate temporal stability as well as good validity. They also suggest that this is a three-dimensional scale: humor factor, interpersonal factor and happiness factor. These data allow for the progress of psychology, regarding the assessment and clinical practice among adolescents. The usefulness of the questionnaire should be verified in other age groups, especially in children with less than 12 years old and in a clinical sample. Despite these limitations, the results suggest that CES-DC is useful in the assessment questionnaire of depressive symptoms in adolescents.

Círculos ao invés de linhas: em busca de valores e princípios estruturantes da gestão social: projeto juventude, participação e autonomia (Instituto Universidade Popular - UNIPOP)

The organizations are characterized as dynamic spaces, they are being revisited and redefined, because they constitute structural human spaces and new vain outlines won expression. As it begins, of the non consensus in its conception, it is explicit the complexity degree that is identified in the plurality and diversity, brought by the people that compose them, characterizing it as accomplishment space, of happiness and also of conflict, of relationships of power and organizational limits and from birth and burial of faiths, values, norms, symbols, knowledge and rituals, therefore, deeply human. In that way, to know the administration of the organization is preponderant condition for the format of the human relationships to be delineated in its living. Like this the work makes an option in knowing the social administration, this work tries to know and analyze the values and beginnings of the social administration; revealling characteristics and specificities of the organizational performance of UNIPOP that contribute to the formation of the conception of Social Administration, it tends as source of the information the managers of the institution; to identify the formative values of UNIPOP that contribute to the youths' partner-political action in the community, tends for reference the current students of the organization and last to evaluate values structurates and supporting that interconnection between the organizational Administration, formation youth's program, participation and autonomy and attendance, starting from the existences gained by the exits, of that program. This way, the research will be qualitative, looking for understanding starting from their documents, the existence of those values

Performance-arte : fracasso, tempo e repetição

Vivemos um tempo de incerteza e instabilidade. Vivemos um tempo em que o presente se reproduz e se reinventa continuamente sem a perspectiva de um futuro certo e perdurável. A presente dissertação orienta-se em torno de um corpo de trabalho de experimentação artística que explora a relação entre arte contemporânea e fracasso. Trata-se, aqui, de reflectir sobre a natureza paradoxal do fracasso, sobre a utilidade e inutilidade do fracasso na sociedade e na artecontemporânea ocidental. Entre a intenção e a realização, entre a perspectiva de sucesso e o fracasso alcançado, abre-se um espaço gerador (potência)ocupado pela dúvida e questionamento, suporte essencial do pensamento e da acção humana. Corpo fracasso (descendente de Sísifo) dedicado a tarefas inúteis (nãoprodutivas) e repetitivas no tempo como alternativa ao corpo sucesso (base-docapitalismo), dedicado a tarefas úteis (produtivas) e repetitivas no tempo.
