La difficile reconnaissance du caractère professionnel des atteintes à la santé mentale
Des Ă©volutions rĂ©centes dans la prise en compte des risques psychosociaux ainsi que dans la rĂ©glementation, la jurisprudence et les pratiques administratives, ont permis une amĂ©lioration de la reconnaissance en accidents du travail ou en maladies professionnelles des atteintes Ă la santĂ© mentale. Cependant, les dĂ©marches pour obtenir cette reconnaissance demeurent difficiles pour les salariĂ©s concernĂ©s, du fait de la complexitĂ© des procĂ©dures, mais aussi de l’écart entre le rĂ´le prescrit des acteurs (employeur, mĂ©decin du travail, etc.) et leur conduite rĂ©elle, et enfin Ă cause du retentissement possible de la dĂ©marche sur la situation de la personne. L’accompagnement par des acteurs aux compĂ©tences complĂ©mentaires (mĂ©decin, psychologue, juriste) apparaĂ®t pertinent pour Ă©viter les impasses.Recent developments in the consideration of psychosocial risks, as well as in regulations, jurisprudence and administrative practices have given rise to an improvement in the recognition of mental health damages as occupational accidents or occupational diseases. The formalities to gain this recognition, however, remain complicated for the employees involved because of the procedure complexities, the gap existing between the actors’ (employers, company doctors…) assigned role and actual behavior, last but not least the possible impact of the formalities on the person’s situation. The support offered by people with complementary expertise (doctors, psychologists, jurists…) seems appropriate to avoid reaching deadlock.La reciente evoluciĂłn en la consideraciĂłn de los riesgos psicosociales asĂ como en la reglamentaciĂłn, la jurisprudencia y las prácticas administrativas han permitido una mejora del reconocimiento de los daños a la salud mental como accidentes de trabajo o enfermedades profesionales. Sin embargo, el proceso para obtener este reconocimiento sigue siendo difĂcil para los trabajadores afectados, debido a la complejidad de los procedimientos, pero tambiĂ©n debido a la diferencia entre el rol prescrito de los actores (empleador, mĂ©dico de la empresa, etc.) y su comportamiento real, y, por Ăşltimo, por el posible impacto de este proceso sobre la situaciĂłn de la persona. El acompañamiento por parte de los actores con habilidades complementarias (mĂ©dico, psicĂłlogo, abogado) parece relevante para evitar un impasse
Electron impact excitations of S2 molecules
Low-energy electron impact excitations of S_2 molecules are studied using the
fixed-bond R-matrix method based on state-averaged complete active space SCF
orbitals. Integral cross sections are calculated for elastic electron collision
as well as impact excitation of the 7 lowest excited electronic states. Also,
differential cross sections are obtained for elastic collision and excitation
of the a^1 Delta_g, b^1 Sigma_g^+ and B^3 Sigma_u^- states. The integrated
cross section of optically allowed excitation of the B^3 Sigma_u^- state agrees
reasonably well with the available theoretical result.Comment: 12 pages, 3 figures. Chemical Physics Letters, in pres

À la fois centre d’activités économiques, pôle culturel et destination de la grande majorité des exilés et réfugiés, l’Île-de-France, devenue une “région monde”, est un observatoire privilégié et singulier du phénomène migratoire, qui a contribué à son expansion territoriale et participé à son dynamisme économique. L’histoire de l’immigration postcoloniale en région continue, elle, à s’écrire au quotidien, et d’autres, comme celle des mouvements de sans-papiers et de mal-logés, y sont en deveni
Stable Isotope Evidence for Dietary Overlap between Alien and Native Gastropods in Coastal Lakes of Northern KwaZulu-Natal, South Africa
Tarebia granifera (Lamarck, 1822) is originally from South-East Asia, but has been introduced and become invasive in many tropical and subtropical parts of the world. In South Africa, T. granifera is rapidly invading an increasing number of coastal lakes and estuaries, often reaching very high population densities and dominating shallow water benthic invertebrate assemblages. An assessment of the feeding dynamics of T. granifera has raised questions about potential ecological impacts, specifically in terms of its dietary overlap with native gastropods.A stable isotope mixing model was used together with gut content analysis to estimate the diet of T. granifera and native gastropod populations in three different coastal lakes. Population density, available biomass of food and salinity were measured along transects placed over T. granifera patches. An index of isotopic (stable isotopes) dietary overlap (IDO, %) aided in interpreting interactions between gastropods. The diet of T. granifera was variable, including contributions from microphytobenthos, filamentous algae (Cladophora sp.), detritus and sedimentary organic matter. IDO was significant (>60%) between T. granifera and each of the following gastropods: Haminoea natalensis (Krauss, 1848), Bulinus natalensis (KĂĽster, 1841) and Melanoides tuberculata (MĂĽller, 1774). However, food did not appear to be limiting. Salinity influenced gastropod spatial overlap. Tarebia granifera may only displace native gastropods, such as Assiminea cf. ovata (Krauss, 1848), under salinity conditions below 20. Ecosystem-level impacts are also discussed.The generalist diet of T. granifera may certainly contribute to its successful establishment. However, although competition for resources may take place under certain salinity conditions and if food is limiting, there appear to be other mechanisms at work, through which T. granifera displaces native gastropods. Complementary stable isotope and gut content analysis can provide helpful ecological insights, contributing to monitoring efforts and guiding further invasive species research
