Didactique de la géographie et formation initiale des enseignants spécialistes : conception et première évaluation du nouveau dispositif de formation initiale des enseignants de géographie du Secondaire supérieur à la HEP Vaud

Geography as a school subject is specifically thought for and by the schools. The contents of the school subject, nowadays, do not reflect the concerns and the evolution of the discipline as such. Nevertheless, official curricula set school objectives that address issues affecting the world and people's lives. These issues are coherent with the ones addressed by geography as a social science, that is to say the study of how people and their environment interact and how societies are interconnected through space. On an every day basis, Geography as a school subject is most of the time reduced to accumulating knowledge outside any given context. This knowledge may even be partially untrue or old and the related activities focus on low cognitive tensions. These practices do not contribute to the learners' understanding of the world because it does not allow them to build a geographical competence, which they. will need as future citizens in order to make responsible choices when they are confronted to questions related to how the locations of human and physical features are influenced by each other and how they interact across space. The central part of the text relies on the ideas and the processes discussed in the publications, which constitute the published file; it is divided into two parts. The first part (chapter 4) presents a didactic approach, which gives meaningful insights into Geography as a school subject and shows a brief account of the theoretical background that supports it. This socio-constructivist approach relies on the main following features: a priming stage (élément déclencheur), which presents geographical knowledge as an issue to be explored, discussed or solved; the issue is given to learners;. the planning of the teaching-learning sequence in small units launched by the main issue in the priming stage ; the interconnections of geographical knowledge with integrative concepts ; the synthetic stage or reporting stage where final concepts and knowledge are put together in order to be learned. Such an approach allows learners to re-invest the knowledge they have built themselves. This knowledge is organised by geographical integrative concepts, which represent true thinking operative tools and with which key issues in the geographical thinking are associated. The second part of the text (chapter 5) displays the didactic principles that governed the conception of the new initial training course for the future upper secondary school teachers at the HEP Vaud. The ambition of this course is to prepare future teachers to plan and realize the teaching of geography that provides pupils with the tools to understand better how people and their environment interact and how societies are interconnected through space. One of the tools for the teachers is the conceptual framework, whose most salient interest is to be relevant at every stage of the preparation and planning of the teaching, including the necessary epistemological reflection that should always be present. The synthesis of the text starts with a short account of the first evaluation of the new course. Various reflections on the future concerns and issues, that the didactics and methodology of Geography will be confronted with, constitute the synthesis.

Vers une conception intégrative de la dépression du sujet âgé : structure cérébrale, cognition et personnalité

Contexte : la prévalence des épisodes dépressifs majeurs parmi la population âgée générale est de 1-4%. Plusieurs études proposent la dissociation entre la dépression à début tardive (late onset depression, LOD), plus souvent associée à des déficits neuropsychologiques, des lésions cérébrales et des facteurs de risque cardio-vasculaire, et la dépression à début précoce (early onset depression, EOD) associée, elle, aux facteurs génétiques et à certains profiles de personnalité. Toutefois, aucune étude transversale ou longitudinale n'a jusqu'à maintenant mesuré et comparé de façon concomitante les profiles cognitifs, la neuro-imagerie (IRM) et les profiles de personnalité des patients âgés LOD et EOD euthymiques. Méthodes : ce travail se base sur une étude menée par différents services des Hôpitaux Universitaires de Genève (HUG) et du Centre Hospitalier Universitaire Vaudois (CHUV) qui ont collaboré afin de recruter le collectif de patients dépressifs nécessaire. La partie expérimentale est divisée en deux parties. La première, transversale, compare 30 EOD, 11 LOD et 30 sujets contrôles, puis 38 EOD à 62 sujets contrôles. Une évaluation neuropsychologique, des évaluations des lésions et volumes cérébraux à l'IRM, ainsi que des traits de personnalité ont été effectuées. La deuxième partie, longitudinale, évalue sur 2 ans 28 patients EOD à 48 sujets contrôles avec les mêmes outils. Résultats : lors de la première partie, transversale, les performances cognitives et les volumes cérébraux sont préservés chez les patients EOD, alors que les patients LOD présentent une réduction significative de la mémoire épisodique et un taux plus élevé de lésions cérébrales périventriculaires (hyperintensités de la matière blanche) en comparaison avec les patients EOD et les sujets contrôles. Au niveau des traits de personnalité, les patients EOD sont associés à un niveau élevé de Névrosisme, en particulier les facettes Anxiété (N1) et Dépression (N3) mais diminué d'Extraversion, en particulier les facettes Chaleur (E1) et Emotions positives (E6). Dans la seconde partie, longitudinale, les performances cognitives et les volumes cérébraux des patients EOD sont restés, après les 2 ans de suivi (follow-up) comparables aux sujets contrôles. Les niveaux élevés du Névrosisme et sa facette Anxiété (N1) constatés au baseline diminuèrent pour atteindre un niveau normal. Les niveaux diminués des facettes Chaleur (E1) et Emotions positives (E6) au baseline ne persistèrent pas non plus. Seule la facette Dépression (N3) est restée chez les patients EOD significativement plus élevée que chez les sujets contrôles après les 2 ans de suivi. Conclusion : nos résultats supportent la dissociation entre EOD, associée à des facteurs génétiques et psychosociaux, et LOD associée aux facteurs de risque et comorbidités cardio-vasculaires. Après rémission d'un épisode dépressif aigu, les performances cognitives ainsi que les volumes cérébraux des patients EOD restent intactes au long terme, alors que le patient LOD garde des lésions cérébrales ainsi que des atteintes au niveau de la mémoire épisodique. Au niveau de la personnalité, la facette Dépression (N3) du domaine Névrosisme, connu pour être un facteur de risque de dépression, reste une caractéristique bien présente chez le patient EOD.

Generating Brand Equity through Corporate Social Responsibility to Key Stakeholders

In this paper we argue that socially responsible policies have a positive impact on a firm's brand equity in the short-term as well as in the long-term. Moreover, once we distinguish between different stakeholders, we posit that secondary stakeholders such as community are even more important than primary stakeholders (customers, shareholders, workers and suppliers) in generating brand equity. Policies aimed at satisfied community interests act as a mechanism to reinforce trust that gives further credibility to social responsible polices with other stakeholders. The result is a decrease in conflicts among stakeholders and greater stakeholder willingness to provide intangible resources that enhance brand equity. We provide support of our theoretical contentions making use of a panel data composed of 57 firms from 10 countries (the US, Japan, South Korea, France, the UK, Italy, Germany, Finland, Switzerland and the Netherlands) for the period 2002 to 2007. We use detailed information on brand equity obtained from Interbrand and on corporate social responsibility (CSR) provided by the SiRi Global Profile database, as compiled by the Sustainable Investment Research International Company (SiRi).

Aromatherapy and nursing: historical and theoretical conception

Abstract Aromatherapy is a Practical or Complementary Health Therapy that uses volatile concentrates extracted from plants called essential oils, in order to improve physical, mental and emotional well-being. Aromatherapy has been practiced historically and worldwide by nurses and, as in Brazil is supported by the Federal Nursing Council, it is relevant to discuss this practice in the context of Nursing through Theories of Nursing. This study of theoretical reflection, exploratory and descriptive, aims to discuss the pharmacognosy of essential oils, the historical trajectory of Aromatherapy in Nursing and the conceptions to support Aromatherapy in light of eight Nursing Theorists (Florence Nightingale, Myra Levine, Hildegard Peplau, Martha Rogers, Callista Roy, Wanda Horta, Jean Watson and Katharine Kolcaba), contributing to its inclusion as a nursing care practice.

Responsibility-allevation and effort provision in a gift-exchange experiment

Previous indirect evidence suggests that impulses towards pro-socialbehavior are diminished when an external authority is responsiblefor an outcome. The responsibility-alleviation effect states that ashift of responsibility to an external authority dampens internalimpulses toward honesty, loyalty, or generosity. In a gift-exchangeexperiment, we find that subjects respond with more generosity(higher effort) when a wage is determined by a random process thanwhen it is assigned by a third party, indicating that even a slightshift in perceived responsibility for the final payoffs can changebehavior. Responsibility-alleviation is a factor in economicenvironments featuring substantial personal interaction.
