Abordagens ao ensino e práticas de questionamento no ensino superior

A emergência de uma nova Sociedade baseada na Informação e no Conhecimento despoletou transformações pedagógicas profundas nas instituições de Ensino Superior. Esta agenda para a inovação, no sentido de um ensino mais centrado nos alunos e no desenvolvimento de competências, tem exigido um esforço acrescido de toda a comunidade académica e, sobretudo, por parte dos professores universitários. Num contexto de recetividade para a mudança, mas com dificuldade de operacionalização da mesma, este estudo visa contribuir para a compreensão e superação de fatores que parecem dificultar a transposição da inovação para as práticas de ensino-aprendizagem correntes, através de duas frentes investigativas: i) caracterizar os docentes na sua dimensão conceptual, o que pensam e o que os motiva, e na sua dimensão prática, isto é, as estratégias didáticas que adotam e adaptam; e ainda, ii) criar oportunidades de concretização de inovação através do desenho de estratégias promotoras de questionamento dos alunos, e também dos docentes. A formulação de questões, e a procura de respostas, é reconhecida como sendo fundamental no desenvolvimento e na aplicação de competências centrais, tais como o pensamento crítico e reflexivo, sendo igualmente importante na resolução de problemas. Assim, numa articulação dinâmica entre conhecer, compreender e agir, a investigação envolveu uma colaboração próxima com um grupo de quatro docentes universitários, ao longo de dois anos letivos consecutivos (2009/2010 e 2010/2011), na conceptualização e implementação de diversas estratégias didáticas impulsionadoras do questionamento dos alunos, promovendo-se igualmente o questionamento reflexivo nos docentes. O trabalho foi desenvolvido no contexto de duas unidades curriculares semestrais (Microbiologia e Temas e Laboratórios em Biologia), destinadas sobretudo a alunos do primeiro ano. Enquanto estudo longitudinal de casos múltiplos, com características etnográficas e de investigação-ação, o trabalho de campo envolveu a combinação de diversos métodos de recolha de dados. Realizaram-se várias observações de aulas, assim como entrevistas semi-estruturadas, aos quatro professores colaboradores, e a alguns dos seus alunos. Aplicou-se ainda, em momentos específicos da investigação, uma versão portuguesa do Approaches to Teaching Inventory – ATI (Trigwell, Prosser, & Ginns, 2005) aos docentes. Recolheram-se também todos os documentos escritos produzidos pelos alunos e pelos professores no âmbito da investigação. Todo o desenho investigativo, assim como a análise dos dados, nomeadamente análise de conteúdo e análise documental, encontra-se fundamentado na literatura teórico-empírica de três áreas da especialidade: estudo do questionamento, análise do discurso oral em contexto de aulas de ciências e estudo das conceções e práticas de ensino dos docentes universitários, destacando-se nesta última a linha investigativa das Abordagens ao Ensino. Os resultados obtidos, assim como a reflexão sobre o percurso investigativo, possibilitaram a obtenção de contributos inovadores e úteis no sentido da promoção de um Ensino Superior de qualidade. Por um lado, são de salientar as evidências recolhidas com os quatro casos (docentes) que apontam para uma natureza integrativa das conceptualizações de ensino, constituindo um contributo teórico relevante para o debate académico desta área. Por outro, foi possível aceder a dinâmicas associadas à formulação de questões por docentes universitários em contexto de aulas teórico-práticas e práticas, através do desenvolvimento e aplicação de um modelo de categorização de questionamento. Por fim, a conjugação de evidências do campo das ‘teorias de ensino’ (observação indireta) com as ‘práticas de ensino’ (observação direta) dos docentes possibilitou a identificação e caracterização de uma possível relação entre Práticas de Questionamento e Abordagens ao Ensino de professores universitários, ampliando desta forma o modelo conceptual de Keith Trigwell e colaboradores (Trigwell, Prosser, & Taylor, 1994). Enquanto investigação híbrida que se orientou por princípios do paradigma interpretativo-naturalista, e, também, do paradigma sócio-crítico, foi igualmente possível identificar um conjunto de recomendações específicas para a inovação e para a reflexividade, no sentido de estimular a comunidade académica, e os professores universitários em particular, a agirem como promotores de estratégias didáticas centradas no desenvolvimento de competências.

Developmental Antecedents of Proactive and Reactive Rebelliousness: The Role of Parenting Style, Childhood Adversity, and Attachment

Adolescence is a time of developmental transition that for one in five young people is characterised by feelings of oppositionality, rebellion, and negativism. Despite the prevalent experience of teen turbulence and despite its significance within the phenomenological framework provided by reversal theory (RT), the childhood antecedents of rebelliousness in adolescence and adulthood have not been given extensive empirical attention within RT, although such work has been carried out using other constructs and theories. We examined recalled parenting style, childhood adversity, and attachment style in adulthood as correlates of proactive and reactive rebelliousness in a sample of 80 participants, aged 18 to 50 years. Each participant responded to a questionnaire package containing the revised Adult Attachment Scale, the Parental Bonding Instrument, the Childhood Experience of Care and Abuse Questionnaire, and the Negativism Dominance Scale. We found that paternal abusive parenting, followed by paternal parenting style, paternal neglect, and paternal antipathy were independently predictive of scores on proactive rebelliousness, the sensation-seeking form. Maternal and paternal indifferent parenting styles each were found to equivalently and independently predict scores on reactive rebelliousness, the interpersonal disaffection form. The results of this study suggest these two forms of rebelliousness may have distinctly different antecedents. A longitudinal study is needed to examine the potentially causal pathways that are suggested by the results of this cross-sectional research. We consider reversal theory explanations of these results and contrast them with complementary theoretical frameworks.

L'adoption d'une innovation technopédagogique par une communauté enseignante universitaire

Résumé: L'adoption d'une innovation technopédagogique par une communauté enseignante universitaire La thèse traite de l'adoption d'une innovation technopédagogique par une communauté enseignante universitaire. Cette étude longitudinale, réalisée dans le cadre d'une recherche-action, vise à comprendre la dynamique globale du processus d'adoption d'une innovation. Le cadre de réflexion théorique de l'étude provient de la recherche en management, en systèmes d'information et en éducation. Il tient à la fois compte des motivations et des besoins des individus (dimension individuelle), de la compatibilité des technologies de l'information selon les théories usuelles de l'apprentissage (dimension pédagogique) et du type de soutien à offrir aux utilisatrices-utilisateurs (dimension organisationnelle). Le modèle d'accompagnement émergeant de cette recherche se compose de cycles itératifs au cours desquels un groupe définit et résout un problème, puis réfléchit successivement aux enjeux émergents d'un cycle à l'autre. Le modèle tient explicitement compte des trois éléments clés suivants: l'individu, la pédagogie et l'organisation qui forment une dynamique systémique indissociable et en interaction les unes les autres pendant toute la durée du processus d'adoption de l'innovation. Il met aussi en lumière la nécessité de stimuler une réflexion critique grâce au concours de ressources externes crédibles pour déterminer la compatibilité des technologies à partir d'expériences concrètes. Une telle démarche participative systématique permet d'accroître la cohésion des idées du groupe par le dialogue et les débats d'opinions_ Par ailleurs, la proximité avec notre milieu de recherche sur une période de deux ans offre la possibilité de saisir plusieurs facettes de la dynamique organisationnelle. Lorsque l'on réalise une étude longitudinale qui met en évidence l'incidence d'événements concomitants, on constate la fragilité du processus et la réversibilité de la décision d'adoption. L'intention d'adoption évolue constamment au gré des expériences des individus et du contexte qui évolue lui-même. L'établissement de relations partenariales avec les groupes intéressés représente une activité essentielle pour pallier ou neutraliser les effets indésirables d'événements concomitants.||Abstract: This thesis deals with a university teaching community adopting a technological/pedagogical innovation. This longitudinal study--part of an action-research study--aims at gaining understanding of the overall dynamics involved in adopting an innovation. The study's conceptual framework derives from management, information-systems, and teaching research. It takes into account the motivations and needs of individuals (individual dimension), the compatibility of information technologies according to current learning theories (pedagogical dimension), and the type of support to be offered to users (organizational dimension). The companion model issuing from this research work comprises iterative cycles during which a group defines and solves a problem and then successively reflects on the issues emerging from one cycle to the next. The model takes explicit account of three key elements: the individual, pedagogical approach, and organization form an indissociable system dynamic in which all dimensions interact during the entire process of adopting innovation. It also sheds light on the need to stimulate critical reflection about the combination of credible external resources so that tangible experiences can be used to determine technology compatibility. This kind of systematic participative process yields greater cohesiveness of group ideas through dialogue and discussion. Moreover, the proximity to our research setting over two years provides the opportunity to seize the many facets of organizational dynamics. During the course of a longitudinal study that highlights the incidence of concomitant events, the fragility of the process and reversibility of the adoption decision become apparent. The adoption intention constantly fluctuates through the experiences of individuals and the context, which also changes. Establishing partnership relations with interested groups stands out as an essential activity in attenuating or counteracting the undesirable effects produced by concomitant events.

Stéaryle CoA désaturase en lien avec le syndrome métabolique chez les adultes de la Polynésie française

Objectif : Évaluer l’association entre l’activité estimée du stéaryle-CoA désaturase (SCD) et le syndrome métabolique (MetS) chez une population adulte de la Polynésie française. Méthode : Étude transversale (2006-2007) de 178 adultes vivants en zone urbaine (Papeete, île de Tahiti, archipel de la Société) et rurale (Tubuai, île de Tubuai, archipel des Australes). L’activité estimée de la SCD a été calculée par le ratio produit/précurseur d’acides gras mesurés dans la membrane des érythrocytes (SCD = C16:1n-7/C16:0). Le MetS a été défini selon les critères du NIH (National Institutes of Health, États-Unis). L’analyse de covariance a été utilisée pour comparer la composition en acide gras sanguin et l’activité estimée de la SCD selon la présence de MetS et de différents critères du MetS. La régression logistique multiple a été utilisée afin d’évaluer l’association entre l’activité estimée de la SCD en quartiles et le risque de MetS. Résultats : La prévalence de surpoids était de 87 % (dont 59 % d’obèses) et celle du MetS de 32 %. Les niveaux du précurseur du C16:1n-7, l’acide palmitoléique (C16:0), entre les participants avec et sans MetS étaient similaires. Le niveau d’activité estimée de la SCD était plus élevé chez les participants avec MetS, plus particulièrement chez ceux avec une hypertriglycéridémie. Une activité estimée de la SCD plus élevée était associée positivement à un risque plus élevé de MetS (Ptendance=0,04). Conclusion : Les résultats de notre étude suggèrent qu’une augmentation de l’activité estimée de la SCD est associée positivement au risque de MetS chez la population adulte de la Polynésie française. Une étude longitudinale serait requise afin de confirmer cette association.

Rhetoric and Realities of London 2012 Olympic Education and Participation ‘Legacies’: Voices from the Core and Periphery

A legacy emphasis was one of the fundamental pillars of the London 2012 Olympic Games. The notion of an Olympic legacy was predicated on assumptions that the event’s value would not purely derive from the sporting spectacle, but rather, from the ‘success’ of enduring effects met out in London and across the country. For physical education students and practitioners, Olympic legacy agendas translated into persistent pressure to increase inspiration, engagement, participation and performance in the subject, sport and physical activity. Responding to this context, and cogniscent of significant disciplinary scholarship, this paper reports initial data from the first phase of a longitudinal study involving Key Stage Three (students aged 11-13) cohorts in two comparable United Kingdom schools: the first an inner-city (core) London school adjacent to the Olympic Park in Stratford, East London (n=150); the second, a (peripheral) school in the Midlands (n=198). The research involved the use of themed questionnaires focusing on self-reported attitudes toward the Olympic Games, and, experiences of physical education, sport and physical activity. Students from both schools demonstrated a wide variety of attitudes toward physical education and sport; yet, minor variances emerged regarding extreme enthusiasm levels. Both cohorts also expressed considerably mixed feelings toward the impending Olympic Games. Strong and variable responses were also reported regarding inspiration levels, ticketing acquisition and engagement levels. Consequently, this investigation can be read within the broader context of legacy debates, and, aligns well with physical educationalists’ on-going discomfort regarding legacy imperatives being enforced upon the discipline and its practitioners. Our work reiterates a shared disciplinary scepticism that while an Olympic Games may temporarily affect young peoples’ affectations for sport (and maybe physical education and physical activity), it may not provide the best, or most appropriate, mechanism for sustained attitudinal and/or social changes en masse.

Increasing inter-generational social mobility: is educational expansion the answer?

Reforms which increase the stock of education in a society have long been held by policy-makers as key to improving rates of intergenerational social mobility. Yet, despite the intuitive plausibility of this idea, the empirical evidence in support of an effect of educational expansion on social fluidity is both indirect and weak. In this paper we use the raising of the minimum school leaving age from 15 to 16 years in England and Wales in 1972 to estimate the effect of educational participation and qualification attainment on rates of intergenerational social class mobility. Because, in expectation, children born immediately before and after the policy was implemented are statistically exchangeable, the difference in the amount of education they received may be treated as exogenously determined. The exogenous nature of the additional education gain means that differences in rates of social mobility between cohorts affected by the reform can be treated as having been caused by the additional education. The data for the analysis come from the ONS Longitudinal Study, which links individual records from successive decennial censuses between 1971 and 2001. Our findings show that, although the reform resulted in an increase in educational attainment in the population as a whole and a weakening of the association between attainment and class origin, there was no reliably discernible increase in the rate of intergenerational social mobility.

A gestão dos resíduos hospitalares e o papel da autoridade de saúde : caso do concelho da Amad

RESUMO O Problema. A natureza, diversidade e perigosidade dos resíduos hospitalares (RH) exige procedimentos específicos na sua gestão. A sua produção depende do número de unidades de prestação de cuidados de saúde (upcs), tipo de cuidados prestados, número de doentes observados, práticas dos profissionais e dos órgãos de gestão das upcs, inovação tecnológica, entre outros. A gestão integrada de RH tem evoluído qualitativamente nos últimos anos. Existe uma carência de informação sobre os quantitativos de RH produzidos nas upcs e na prestação de cuidados domiciliários, em Portugal. Por outro lado, os Serviços de Saúde Pública, abrangendo o poder de Autoridade de Saúde, intervêm na gestão do risco para a saúde e o ambiente associado à produção de RH, necessitando de indicadores para a sua monitorização. O quadro legal de um país nesta matéria estabelece a estratégia de gestão destes resíduos, a qual é condicionada pela classificação e definição de RH por si adoptadas. Objectivos e Metodologias. O presente estudo pretende: quantificar a produção de RH resultantes da prestação de cuidados de saúde, em seres humanos e animais nas upcs, do sistema público e privado, desenvolvendo um estudo longitudinal, onde se quantifica esta produção nos Hospitais, Centros de Saúde, Clínicas Médicas e Dentárias, Lares para Idosos, Postos Médicos de Empresas, Centros de Hemodiálise e Clínicas Veterinárias do Concelho da Amadora, e se compara esta produção em dois anos consecutivos; analisar as consequências do exercício do poder de Autoridade de Saúde na gestão integrada de RH pelas upcs; quantificar a produção média de RH, por acto prestado, nos cuidados domiciliários e, com um estudo analítico transversal, relacionar essa produção média com as características dos doentes e dos tratamentos efectuados; proceder à análise comparativa das definições e classificações de RH em países da União Europeia, através de um estudo de revisão da legislação nesta matéria em quatro países, incluindo Portugal. Resultados e Conclusões. Obtém-se a produção média de RH, por Grupos I+II, III e IV: nos Hospitais, por cama.dia, considerando a taxa de ocupação; por consulta, nos Centros de Saúde, Clínicas Médicas e Dentárias e Postos Médicos de Empresas; por cama.ano, nos Lares para Idosos, considerando a sua taxa de ocupação; e por ano, nas Clínicas de Hemodiálise e Veterinárias. Verifica-se que a actuação da Autoridade de Saúde, produz nas upcs uma diferença estatisticamente significativa no aumento das contratualizações destas com os operadores de tratamento de RH. Quantifica-se o peso médio de resíduos dos Grupos III e IV produzido por acto prestado nos tratamentos domiciliários e relaciona-se esta variável dependente com as características dos doentes e dos tratamentos efectuados. Comparam-se os distintos critérios utilizados na elaboração das definições e classificações destes resíduos inscritas na legislação da Alemanha, Reino Unido, Espanha e Portugal. Recomendações. Apresentam-se linhas de investigação futura e propõe-se uma reflexão sobre eventuais alterações de aspectos específicos no quadro legal português e nos planos de gestão integrada de RH, em Portugal. ABSTRACT The problem: The nature, diversity and hazardousness of hospital wastes (HW) requires specific procedures in its management. Its production depends on the number and patterns of healthcare services, number of patients, professional and administration practices and technologic innovations, among others. Integrated management of HW has been developping, in the scope of quality, for the past few years. There is a lack of information about the amount of HW produced in healthcare units and in the domiciliary visits, in Portugal. On the other hand, the Public Health Services, embracing the Health Authority’s power, play a very important role in managing the risk of HW production to public and environmental health. They need to use some indicators in its monitorization. In a country, rules and regulations define hospital waste management policies, which are confined by the addopted classification and definition of HW. Goals and Methods: This research study aims to quantify the production of HW as a result of healthcare services in human beings and animals, public service and private one. Through a longitudinal study, this production is quantified in Hospitals, Health Centers, Medical and Dental Clinics, Residential Centers for old people, Companies Medical Centers and Veterinary and Haemodyalisis Clinics in Amadora’s Council, comparing this production in two consecutive years. This study also focus the consequences of the Health Authority’s role in the healthcare services integrated management of HW. The middle production of HW in the domiciliary treatments is also quantified and, with a transversal analytic study, its association with patients and treatments’ characteristics is enhanced. Finally, the definitions and classifications in the European Union Countries are compared through a study that revises this matter’s legislation in four countries, including Portugal. Results and Conclusions: We get the middle production of Groups I+II, III and IV: HW: in Hospitals, by bed.day, bearing the occupation rate; by consultation, in Health Centers, Medical and Dental Clinics and Companies Medical Centers; by bed.year in Residential Centers for old people, considering their occupation rate; by year, in Veterinary and Haemodyalisis Clinics. We verify that the Health Authority’s role produces a significative statistical difference in the rise of the contracts between healthcare services and HW operators. We quantify the Groups III and IV’s wastes middle weight, produced by each medical treatment in domiciliary visits and relate this dependent variable with patients and treatments’ characteristics. We compare the different criteria used in the making of definitions and classifications of these wastes registered in German, United Kingdom, Spain and Portugal’s laws. Recommendations: Lines of further investigation are explaned. We also tender a reflexion about potential changes in rules, in regulations and in the integrated plans for managing hospital wastes in Portugal. RÉSUMÉ Le Problème. La gestion des déchets d'activités hospitalières (DAH) et de soins de santé (DSS) exige des procédures spécifiques en raison de leur nature, diversité et dangerosité. Leur production dépend, parmi d’autres, du nombre d’unités de soins de santé (USS), du type de soins administrés, du nombre de malades observés, des pratiques des professionnels et des organes de gestion des USS, de l’innovation technologique. La gestion intégrée des DAH et des DSS subit une évolution qualitative dans les dernières années. Il existe un déficit d’information sur les quantitatifs de DAH et de DSS provenant des USS et de la prestation de soins domiciliaires, au Portugal. D’autre part les Services de Santé Publique, y compris le pouvoir de l’Autorité de Santé, qui interviennent dans la gestion du risque pour la santé et pour l’environnement associé à la production de DAH et de DSS, ont besoin d’indicateurs pour leur surveillance. Dans cette matière le cadre légal établit la stratégie de gestion de ces déchets, laquelle est conditionnée par la classification et par la définition des DAH et des DSS adoptées par le pays. Objectifs et Méthodologie. Cet étude prétend: quantifier la production de DAH et de DSS provenant de la prestation de soins de santé, en êtres humains et animaux dans les USS du système public et privé. À travers un étude longitudinal, on quantifie cette production dans les Hôpitaux, Centres de Santé, Cliniques Médicales et Dentaires, Maisons de Repos pour personnes âgées, Cabinets Médicaux d’ Entreprises, Centres d’Hémodialyse et Cliniques Vétérinaires du municipe d’ Amadora, en comparant cette production en deux ans consécutifs; analyser les conséquences de l’exercice du pouvoir de l’Autorité de Santé dans la gestion intégrée des DAH et des DSS par les USS; quantifier la production moyenne de DAH et de DSS dans la prestation de soins domiciliaires et, avec un étude analytique transversal, rapporter cette production moyenne avec les caractéristiques des malades et des soins administrés; procéder à l’ analyse comparative des définitions et classifications des DAH et des DSS dans des pays de l’Union Européenne, à travers un étude de révision de la législation relative à cette matière dans quatre pays, Portugal y compris. Résultats et Conclusions. On obtient la production moyenne de DAH et des DSS, par Classes I+II, III et IV: dans les hôpitaux, par lit.jour, en considérant le taux d’occupation; par consultation, dans les Centres de Santé, Cliniques Médicales et Dentaires et Cabinets Médicaux d’ Entreprises par lit.an dans les Maisons de Repos pour personnes âgées en considérant le taux d’occupation; et par an, dans les Cliniques d’Hémodialyse et Vétérinaires. On constate que l’actuation de l’Autorité de Santé produit dans les USS une différence statistiquement significative dans l’accroissement de leurs contractualisations avec les opérateurs de traitement de DAH et de DSS. On quantifie le poids moyen des déchets des Classes III et IV produit par acte de prestation de soins à domicile et on rapporte cette variable dépendante avec les caractéristiques des malades et des soins administrés. On compare les différents critères utilisés dans l’élaboration des définitions et des classifications de ces déchets inscrites dans la légis

The effects of parental sensitivity and involvement in caregiving on mother–infant and father–infant attachment in a portuguese sample

In the present longitudinal study, we investigated attachment quality in Portuguese mother–infant and in father–infant dyads, and evaluated whether attachment quality was related to parental sensitivity during parent–infant social interaction or to the amount of time each parent spent with the infant during play and in routine caregiving activities (e.g., feeding, bathing, play). The sample consisted of 82 healthy full-term infants (30 girls, 53 boys, 48 first born), and their mothers and fathers from mostly middle-class households. To assess parental sensitivity, mothers and fathers were independently observed during free play interactions with their infants when infants were 9 and 15 months old. The videotaped interactions were scored by masked coders using the Crittenden’s CARE-Index. When infants were 12 and 18 months old, mother–infant and father–infant dyads were videotaped during an adaptation of Ainsworth’s Strange Situation. Parents also described their level of involvement in infant caregiving activities using a Portuguese version of the McBride and Mills Parent Responsibility Scale. Mothers were rated as being more sensitive than fathers during parent–infant free play at both 9 and 15 months. There also was a higher prevalence of secure attachment in mother–infant versus father–infant dyads at both 12 and 18 months. Attachment security was predicted by the amount of time mothers and fathers were involved in caregiving and play with the infant, and with parents’ behavior during parent–infant free play.

Atividade física, ansiedade e gravidez

Introdução: A gravidez e a prática da atividade física (AF) são temas ainda pouco abordados na nossa sociedade. Muitas mulheres sofrem de ansiedade no período pré-natal e não conhecem os benefícios que a prática da AF tem sobre a mesma. Estudos demonstram que a AF está associada à diminuição da ansiedade, contudo poucos avaliam este efeito na gravidez. Objetivo(s): Os objetivos deste estudo foram classificar o nível de AF das grávidas; avaliar os sintomas de ansiedade e analisar a associação entre os níveis de ansiedade e a AF das gestantes. Métodos: Trata-se de um estudo longitudinal prospetivo, realizado numa amostra de 56 grávidas com idades entre os 18 e os 37 anos (29,14 ±4,641 anos). As participantes foram avaliadas em dois momentos, T1 (10-12 semanas gestacionais) e T2 (20-22 semanas gestacionais), tendo sido mensurada a AF com acelerómetros GTX3 e a ansiedade com a escala de Zung. Resultados: A média da AF leve e moderada não apresentou diferenças entre os dois momentos de avaliação; contudo, verificou-se uma tendência para a AF leve diminuir do primeiro para o segundo trimestre (1283,88 ± 530,37 vs 1098,16 ± 489,72 counts/min total semana; p=0,459) e a AF moderada aumentar (2470,62 ± 404,50 vs 2528,55 ± 493,05 counts/min total semana; p=0,459). A maioria das grávidas não cumpriu as recomendações da ACSM nos dois momentos de avaliação (T1: 72,1% e T2: 73,2%) (p=0,06). Não se verificaram diferenças no estado de ansiedade das grávidas de T1 para T2. 10,7% das grávidas apresentaram ansiedade em T1 e 7,1% em T2 (p=0,063). Cumprir ou não as recomendações da ACSM não esteve associado ao estado de ansiedade. Conclusão: Neste estudo verificámos que a maioria das gravidas não cumpre as recomendações da AF segundo ACSM, os níveis de ansiedade não diferiram ao longo da gravidez, verificámos ainda que o cumprimento das recomendações da AF não está associado aos níveis de ansiedade.

Caracterização da adesão terapêutica dos doentes seguidos no Centro Hospitalar Lisboa Norte, EPE, no decurso do tratamento da, Esclerose Múltipla, Esclerose Lateral Amiotrófica, Artrite Reumatóide, Espondilite Anquilosante, Artrite Psoriática, Artrite Idiopática Juvenil Poliarticular, Psoríase em Placas, Polineuropatia Amiloidótica Familiar (Paramiloidose) e HIV/Sida : análise retrospetiva

RESUMO - Objetivos: Caracterizar a adesão à terapêutica nos doentes do CHLN, na área do VIH/SIDA, Esclerose, Artrite Reumatóide, Psoríase e Paramiloidose e avaliar a hipótese de ser possível prever o risco de um doente se tornar, num doente sem adesão. Metodologia: Estudo retrospetivo, observacional e longitudinal, realizado entre Janeiro de 2010 a 31 de Dezembro de 2013, a 4.761 doentes, em que a adesão à terapêutica foi calculada com base nos registos informáticos das dispensas de medicação, efectuados pelos Serviços Farmacêuticos, com recurso à Compliance Rate (CR) e utilizada como variável dependente. A estatística descritiva foi utilizada para caracterizar os doentes e os seus levantamentos e a regressão logística para avaliar o efeito das variáveis (idade, sexo, distrito de residência, período de observação, número de interrupções superiores a trinta dias e tempo até à primeira interrupção) sobre a adesão à terapêutica. Resultados e Conclusões: A percentagem de doentes com adesão foi de 64%, no entanto no HIV/Sida e na Artrite Reumatóide e Psoríase esta percentagem foi significativamente mais baixa, 42% dos doentes interromperam a terapêutica por períodos superiores a 30 dias, ocorrendo essa interrupção maioritariamente entre o primeiro e segundo ano de terapêutica. O modelo de regressão logística permitiu verificar que só com as variáveis sociodemográficas não é possível prever o risco de um doente se tornar num doente sem adesão, sendo para tal necessário adicionar ao modelo a variável número de interrupções superiores a 30 dias que foi identificada como importante factor preditivo da não adesão (OR=15,9, p=0,000).

A comprehensive examination of adolescent gambling

The purposes of this study were: a) to examine the prevalence and consequences associated with adolescent gambling, b) to examine the factors which influence adolescent gambling,. c) to detennine what factors discriminate among four groups of gamblers (no-risk/non-gamblers, low-risk gamblers, at-risk gamblers, and high-risk/problematic gamblers), and d) to examine the relation of gambling to nine other risk behaviours (i.e., alcohol use, smoking, marijuana use, hard drug use, sexual activity, minor delinquency, major delinquency, direct aggression, and indirect aggression). Adolescents (N = 3,767) from 25 secondary schools completed a twohour survey that assessed involvement in risk be~aviours as well as potential predictors from a wide range of contexts (school, neighbourhood, family, peer, and intrapersonal). The majority of adolescents reported gambling, although the frequency of gambling participation was low. The strongest predictors/discriminators of gambling involvement were gender, unstructured activities, structured activities, and risk attitudes/perceptions. In addition, the examination of the co-occurrence of gambling with other risk behaviours revealed that for high-risk/problem gamblers, the top three most frequent co-occurring high-risk behaviours were direct aggression, minor delinquency and alcohol. This study was the first to examine the continuum of gambling involvement (i.e., non-gambling to high risk/problematic gambling) using a comprehensive set ofpotential predictors with a large sample of secondary school students. The findings of this study support past research and theories (e.g., Theory of Triadic Influence) which suggest the importance ofproximal variables in predicting risk behaviors. The next step, however, will be to examine the direct and indirect 1 effects of the ultimate (e.g., temperament), distal (e.g., parental relationship), and proximal variables (e.g., risk attitudes/perceptions) on gambling involvement in a longitudinal study.

Risk-taking behaviours in adolescent boys and girls : sexuality and dietary health

This study examined adolescents' reported sexual and dietary health-risk behaviours and perceptions. Specifically, this study analyzed the data of 600 students (300 male~ 300 female) in grades 9, I 1, and OAC (mean, standard deviation). The mean age of the students in the sample is 16 with a standard deviation of 1.6. The study was a secondary analysis ofthe first-year data of a 3-year longitudinal study conducted by Youth Lifestyle Choices-Community University Research Alliance (YLC-CURA) on adolescents. To explore sexuality and dietary health, this study purposefully selected sections of the survey that represented sex and dieting behaviours of adolescents. Separate gender and age data analyses revealed different patterns among the variables. Specifically., findings revealed that adolescents who engaged in recent sexual activities were more likely to have a relatively more positive body image perception and were relatively more likely to engage in disordered eating. Across both genders and 3 age levels, adolescents reported that despite their unhealthy dietary habits they felt that dieting was not a high-risk behaviour. Results were discussed in terms of educational implication for sexual health programs.

The link between extracurricular activities and academic achievement for youth in grades 5 and 7 /

This study examined the link between involvement in extracurricular activities and academic success for 504 youth in grades 5 and 7, using the first-year survey data from a longitudinal study conducted by Youth Lifestyle Choices-Community University Research Alliance (YLC-CURA). Specifically, the study investigated whether a linear or curvilinear relation existed between extracurricular activities and academic achievement for both in- and out-of-school activities. It was hypothesized that stress may be a possible mediator in the link between extracurricular activities and achievement Results indicated that students in grades 5 and 7 were involved in club and sport activities both inside and outside of school at fairly equal fi-equencies, with a mean frequency of approximately once a month. The hypothesis that a positive relation j between in- and out-of-school extracurricular activities and achievement was supported. The hypothesis that a curvilinear relation would exist between extracurricular activities and achievement was only supported for out-of-school activities. This finding supports the argument that too much or too little involvement in out-of-school activities is related negatively to a student's academic success; however, a moderate amount of involvement appears to be positive. The hypothesis that there would be a relation between involvement in extracurricular activities and stress level for both in-school and out-ofschool activities was not supported. Results were discussed in terms of educational implications and community resources for extracurricular activities.
