Cet article vise à documenter les motifs d'utilisation ou non des services en santé sexuelle chez les jeunes en situation de rue. Trente-trois jeunes en situation de rue (18 à 25 ans) ont été rencontrés en entrevue individuelle. L'analyse qualitative montre que les jeunes utilisent, de façon ciblée, les services biomédicaux dans le but de préserver leur santé sexuelle. Toutefois, le caractère privé et secondaire de la sexualité dans le contexte de la situation de rue fait entrave à l'utilisation qu'ils font des services en santé sexuelle. Ces constats permettent de repenser les services en santé sexuelle offerts aux jeunes en situation de rue.
The development of scientific disciplines constitutes a main sector of the history and sociology of science. In an effort to break with a sociological tradition which too readily associates institutionalization with autonomization, this paper, based upon a comparative study of biology (that part of the discipline closely related to the natural sciences) and psychology, examines how dominant cultural models, political structures, and social relations constantly influence the institutionalization of science.As a relatively narrow scientific field, little known at the level of international scientific activity, the Quebec francophone scientific field often entertains complex and varying relationships with more advanced centers of scientific production that become the object of strategies aimed at assuring it a greater legitimacy. In such a context, the tensions that exist between intellectual and scientific activities, and social demands, remain particularly determinant. These social demands remain insufficiently varied and sustained to assure an intense penetration of scientific activity within the social fabric. As is often seen in such situations, university and government circles are the only structural entities to welcome scientific activity.Le développement de disciplines scientifiques constitue un secteur maintenant central de l'histoire et de la sociologie de la science. Cherchant à rompre avec une tradition sociologique qui concilie trop facilement institutionnalisation et autonomisation, ce texte, à partir d'une étude comparée de la biologie (qui se rapproche des sciences naturelles) et de la psychologie, veut illustrer combien les modèles culturels dominants, les structures politiques et les rapports sociaux marquent constamment l'institutionnalisation de la science même si, devenue activité spécialiséd, celle‐ci peut davantage retraduire les influences sociales subies.Champ scientifique de petite taille, sans grande visibilité au niveau de l'activité scientifi‐que internationale, le champ scientifique québécois francophone entretient avec divers centres plus avancés de la production scientifique des rapports souvent complexes, variables et objets de stratégies visant la conquête d'une plus grande légitimité. Dans un tel contexte, demeurent particuliérement determinantes les tensions entre les activités intellectuelles et scientifiques et les demandes sociales, insuffisamment soutenues et va‐riées pour assurer une intense pénétration de l'activité scientifique dans le tissu social. Comme c'est alors fréquemment le cas dans semblable conjoncture, les milieux universi‐taires et gouvernementaux, pratiquement seuls, servent de structures d'accueil à l'activité scientifique.
Abstract. The recent discovery of voluminous submarine landslides along the Owen Ridge may represent a source of tsunami hazard for the nearby Oman coast. We assess the severity of this potential hazard by performing numerical simulations of tsunami generation and propagation from the biggest landslide (40 km3 in volume) observed along the Owen Ridge. A finite-difference model, assimilating the landslide to a visco-plastic flow, simulates tsunami generation. Computation results show that Salalah city (190 000 inhabitants) is impacted by 2.5 m-high tsunami waves one hour after sediment failure. Higher wave elevation values (4 m) are reached in the low populated Sawqara Bay over 80 min after slide initiation. Although large submarine failures along remote oceanic ridges are infrequent, this study reveals an underestimated source of tsunami hazard in the Arabian Sea.

National audience ; Weed management has become a major challenge in many field cropping systems today, particularly with the spread of herbicide resistant weed populations. The radical changes in the cropping system necessary to break these dead ends are difficult to bring about. The aim of this project is that personalized diagnostic tools would contribute to the changes. We take the example of the resistance of weeds to sulfonylureas to set up an open innovation process aimed at developing tools and creating the largest possible diagnostic community. The DIY-LOL project, « Diagnostic-It-Yourself-LOLium », is the first step in this ambition. It proposes to mobilize a "Do-It-Yourself-Biology" approach to produce and validate a prototype diagnostic tool that can be used in the field by farmers or development technicians. The project will also make it possible to advance in the development of laboratory diagnostic protocols and will create an original dynamic of collaboration between the agricultural world and the "DIY" community. ; La gestion des adventices est aujourd'hui devenue la difficulté majeure de nombreux systèmes de grande culture, en particulier à cause de l'extension de populations d'adventices résistantes aux herbicides. Les changements radicaux de système de culture nécessaires pour sortir de ces impasses sont difficiles à impulser. Le parti pris de ce projet est que des outils de diagnostic personnalisés contribueraient aux changements. Nous prenons l'exemple de la résistance des ivraies aux sulfonylurées pour mettre en place une démarche d'innovation ouverte visant à développer les outils et créer une communauté de diagnostic la plus vaste possible.

Flood mitigation is a strategy that is growing in importance across Europe. This growth corresponds with an increasing emphasis on the need to learn to live with floods and make space for water. Flood mitigation measures aim at reducing the likelihood and magnitude of flooding and complement flood defenses. They are being put in place through the implementation of actions that accommodate (rather than resist) water, such as natural flood management or adapted housing. The strategy has gained momentum over the past 20 years in an effort to improve the sustainability of flood risk management (FRM) and facilitate the diversification of FRM in the pursuit of societal resilience to flooding. Simultaneously, it is increasingly argued that adaptive forms of governance are best placed to address the uncertainty and complexity associated with social-ecological systems responding to environmental challenges, such as flooding. However, there have been few attempts to examine the extent to which current flood risk governance, and flood mitigation specifically, reflect these aspired forms of adaptive governance. Drawing from EU research into flood risk governance, conducted within the STAR-FLOOD project, we examine the governance of flood mitigation in six European countries: Belgium, England, France, the Netherlands, Poland, and Sweden. Using in-depth policy and legal analysis, as well as interviews with key actors, the governance and implementation of flood mitigation in these countries is evaluated from the normative viewpoint of whether, and to what extent, it can be characterized as adaptive governance. We identify five criteria of adaptive governance based on a comprehensive literature review and apply these to each country to determine the "distance" between current governance arrangements and adaptive governance. In conclusion, the flood mitigation strategy provides various opportunities for actors to further pursue forms of adaptive governance. The extent to which the mitigation strategy is capable of doing so varies across countries, however, and its role in stimulating adaptive governance was found to be strongest in Belgium and England.
