La réinsertion professionnelle des bénéficiaires de l'aide sociale en Suisse et en Allemagne

Parmi les régimes sociaux pour les personnes sans emploi en âge de travailler, l'aide sociale compte parmi ceux qui ont été confrontés aux plus grands changements au cours des vingt dernières années. Durant cette période, le nombre et le profil des bénéficiaires a évolué à un tel point qu'il devient aujourd'hui difficile de considérer l'aide sociale uniquement sous le prisme d'un dernier filet de protection sociale intervenant pour une minorité d'individus fortement marginalisés socialement. Aujourd'hui, accompagnant une hausse régulière du nombre de bénéficiaires, le public de l'aide sociale est devenu beaucoup plus hétérogène, incorporant une frange de plus en plus importante de personnes pour qui le chômage de longue durée ou le sous-emploi constituent de fait le principal problème. Loin d'être un phénomène typiquement suisse, la transformation radicale du public touchant des prestations d'aide sociale a en fait touché l'ensemble des pays européens. Ces développements questionnent fondamentalement la mission de l'aide sociale. Traditionnellement, deux missions ont été au centre de l'aide sociale : garantir le minimum vital et favoriser l'intégration sociale des personnes les plus marginalisées socialement. Toutefois, aujourd'hui, avec l'émergence de nouveaux publics, se pose crucialement la question de la réorientation des régimes d'aide sociale vers une prise en charge visant le retour sur le premier marché du travail à plus ou moins long terme. De quels types de mesures de réinsertion professionnelle et de services de placement les bénéficiaires de l'aide sociale disposent-ils en Suisse ? Quels dispositifs organisationnels permettent-ils de garantir une prise en charge orientée vers l'emploi adaptée aux bénéficiaires de l'aide sociale ? En Suisse, bien que la réinsertion professionnelle soit désormais considérée comme une mission intégrale de l'aide sociale au niveau politique, il existe encore peu d'études empiriques sur les pratiques effectives mises en place dans les différents cantons en matière d'aide à la réinsertion professionnelle des bénéficiaires de l'aide sociale. Sans prétendre à l'exhaustivité, cette étude dresse un état des lieux de la situation actuelle en Suisse sur la base des quelques études existantes et d'une enquête par questionnaire réalisée auprès des responsables cantonaux en 2011. Malgré d'importantes différences entre et à l'intérieur des cantons et de nombreuses lacunes dans les données statistiques, un des principaux résultats qui ressort de cette étude est que l'accès des bénéficiaires de l'aide sociale à une prise en charge orientée emploi en Suisse reste problématique à plusieurs égards. En effet, alors que l'offre développée par les services sociaux en matière de mesures de réinsertion professionnelle reste souvent restreinte, d'autres pratiques telles que la collaboration interinstitutionnelle ou le recours aux ORP pour les services de placement présentent aussi plusieurs limites. Une comparaison avec la situation en Allemagne, qui a complètement réorganisé la prise en charge de ses chômeurs de longue durée en 2005 en créant une prestation financière et une structure de prise en charge spécifique à cette catégorie de sans-emplois, confirme le potentiel d'amélioration des efforts réalisés en Suisse, particulièrement en ce qui concerne l'importance accordée au retour à l'emploi et l'accès aux mesures de réinsertion professionnelle les plus prometteuses. Toutefois, et malgré une réduction significative du nombre de chômeurs de longue durée depuis l'introduction de la réforme Hartz IV en 2005, l'expérience allemande indique que la mise sur pied d'une structure spécialisée n'est pas non plus sans créer des problèmes, et que, plus généralement, il est difficile d'imputer le succès d'une politique de réinsertion professionnelle pour les bénéficiaires de l'aide sociale uniquement à son modèle organisationnel

Sexually transmitted infection risk exposure among black and minority ethnic youth in northwest London: findings from a study translating a sexually transmitted infection risk-reduction intervention to the UK setting.

OBJECTIVES: Young black women are disproportionately affected by sexually transmitted infections (STI) in the UK, but effective interventions to address this are lacking. The Young Brent Project explored the nature and context of sexual risk-taking in young people to inform the translation of an effective clinic-based STI reduction intervention (Project SAFE) from the USA to the UK. METHODS: One-to-one in-depth interviews (n = 37) and group discussions (n = 10) were conducted among men and women aged 15-27 years from different ethnic backgrounds recruited from youth and genitourinary medicine clinic settings in Brent, London. The interviews explored the context within which STI-related risks were assessed, experienced and avoided, the skills needed to recognise risk and the barriers to behaviour change. RESULTS: Concurrent sexual partnerships, mismatched perceptions and expectations, and barriers to condom use contributed to STI risk exposure and difficulties in implementing risk-reduction strategies. Women attempted to achieve monogamy, but experienced complex and fluid sexual relationships. Low risk awareness, flawed partner risk assessments, negative perceptions of condoms and lack of control hindered condom use. Whereas men made conscious decisions, women experienced persuasion, deceit and difficulty in requesting condom use, particularly with older partners. CONCLUSIONS: Knowledge of STI and condom use skills is not enough to equip young people with the means to reduce STI risk. Interventions with young women need to place greater emphasis on: entering and maintaining healthy relationships; awareness of risks attached to different forms of concurrency and how concurrency arises; skills to redress power imbalances and building self-esteem

Sediment Sorting and Rounding in a Basaltic Glacio-Fluvio-Aeolian Environment: hrisjkull Glacier, Iceland

Sediments and sedimentary rocks preserve a rich history of environment and climate. Identifying these signals requires an understanding of the physical and chemical processes that have affected sedimentary deposits [1]. Such processes include sorting and rounding during transport and chemical alteration through weathering and diagenesis. Although these processes have long been studied in quartz-dominated sedimentary systems [2], a lack of studies of basaltic sedimentary systems limits our interpretations of the environment and climate where mafic source rocks dominate, such as on Mars [3,4]. As part of the SAND-E: Semi-Autonomous Navigation for Detrital Environments project [5], which uses robotic operations to examine physical and chemical changes to sediments in basaltic glacio-fluvialaeolian environments, this research studies changes in sorting and rounding of fluvial-aeolian sediments along a glacier-proximal-to-glacier-distal transect in the outwash-plain of the risjkull glacier in SW Iceland (Fig. 1

Dynamic Compaction of Biomaterial Powders

Dynamic compaction which requires no external heating for consolidation was used to compact hydroxyapatite. Static precompaction of 3 MPa and dynamic compaction using a projectile velocity of 50 m/s resulted in compacts having a compaction degree of 65% and a tensile strength of 12.4 ± 2.7 MPa This strength was very close to that obtained with sintered compacts one and seemed to indicate that some interparticle boundaries had been created during dynamic compaction

The Geant4-DNA project

The Geant4-DNA project proposes to develop an open-source simulation software based and fully included in the general-purpose Geant4 Monte Carlo simulation toolkit. The main objective of this software is to simulate biological damages induced by ionising radiation at the cellular and sub-cellular scale. This project was originally initiated by the European Space Agency for the prediction of deleterious effects of radiation that may affect astronauts during future long duration space exploration missions. In this paper, the Geant4-DNA collaboration presents an overview of the whole ongoing project, including its most recent developments already available in the last Geant4 public release (9.3 BETA), as well as an illustration example simulating the direct irradiation of a chromatin fibre. Expected extensions involving several research domains, such as particle physics, chemistry and cellular and molecular biology, within a fully interdiciplinary activity of the Geant4 collaboration are also discussed.Comment: presented by S.

Photoluminescence, recombination induced luminescence and electroluminescence in epoxy resin

Dielectric breakdown of epoxies is preceded by light emission, or so-called electroluminescence, from the solid-state material. Very little is known about the luminescence properties of epoxies. The aim of this paper is to derive information that can be used as a basis to understand the nature of the excited states and their involvement in electrical degradation processes. Three different kinds of stimulation were used to excite the material luminescence. Photoluminescence was performed on the base resin, the hardener and the cured resin. Luminescence excited by a silent discharge has been analysed to identify which of the luminescent centres are optically active upon the recombination of electrical charges and could therefore act as charge traps. Finally, the electroluminescence spectrum has been acquired and compared with the previous ones. Although the identification of the origin of these emissions is far from being complete, it has been found that the photoluminescence from the cured resin is due to in-chain chromophores, which acts as trapping centres. The excited states involved in photoluminescence also seems to be involved in electroluminescence, but other components are detected as well, which could be due to the degradation of the resin molecule under the effect of the electric stress

Using XRD to Characterize Sediment Sorting in a Mars Analog Glacio-Fluvio-Eolian Basaltic Sedimentary System in Iceland

The martian surface has a primarily basaltic composition and is dominated by sedimentary deposits. Ancient layered sedimentary rocks have been identified across the planet from orbit, have been studied in situ by the Mars Exploration Rovers and the Mars Science Laboratory rover, and will be studied by the Mars 2020 rover. These ancient sedimentary rocks were deposited in fluvial, lacustrine, and eolian environments during a warmer and wetter era on Mars. It is important to study the composition of sediments in Mars analog environments to characterize how minerals in basaltic sedimentary systems are sorted and/or aqueously altered. This information can help us better interpret sedimentary processes from similar deposits on Mars and derive information about the igneous source rocks. Sediment sorting has been studied extensively on Earth, but not typically in basaltic environments. Previous work has addressed sorting of basaltic sediments through experimental techniques and in modern eolian basaltic systems and aqueous alteration in subglacial and proglacial environments. We add to this body of research by studying sediment sorting and aqueous alteration in a glacio-fluvio-eolian basaltic system in southwest Iceland
