La réalité virtuelle comme outil de lutte contre la victimisation des personnes aßnées
Ce mĂ©moire, qui a pour but dâenrichir les connaissances sur lâutilisation de la rĂ©alitĂ© virtuelle comme outil de lutte contre la victimisation des personnes aĂźnĂ©es, a Ă©tĂ© menĂ© dans le contexte du dĂ©veloppement des Ateliers 360 aĂźnĂ©s de la Fondation Jasmin Roy Sophie Desmarais. Il explore la dĂ©marche de conception du guide dâanimation pour cette activitĂ© et expose une analyse de comment les personnes aĂźnĂ©es y rĂ©agissent. Le dĂ©veloppement du guide repose sur lâanalyse de documentation variĂ©e, des recensions des Ă©crits, dâune entrevue informelle et des consultations avec des partenaires. Il sâinspire de la dĂ©marche de recherche-dĂ©veloppement et est orientĂ© par le cadre thĂ©orique de lâapprentissage socio-Ă©motionnel (CASEL, s.d.). Le projet de recherche quant Ă lui consiste en une Ă©tude de cas multiples qui se penche sur les diffĂ©rentes unitĂ©s de contenus qui composent les Ateliers 360 aĂźnĂ©s. Cinq cas ont Ă©tĂ© formĂ©s, quatre regroupant des personnes aĂźnĂ©es et un des experts en maltraitance. Le cadre conceptuel des facteurs influençant lâexpĂ©rience utilisateur de Morville (2004) a encadrĂ© les collectes de donnĂ©es qui reposaient sur une analyse dâartĂ©facts physiques, un questionnaire sociodĂ©mographique, lâobservation des activitĂ©s, et la tenue de groupes de discussion focalisĂ©s. Il en ressort que les personnes aĂźnĂ©es rĂ©agissent positivement Ă cette activitĂ©, quâelles apprĂ©cient la possibilitĂ© de tester une nouvelle technologie et de faire de nouveaux apprentissages tout en Ă©tant encadrĂ©s par des animateurs compĂ©tents. Plusieurs recommandations pour rendre lâactivitĂ© plus utilisable et accessible aux personnes avec des incapacitĂ©s ont aussi Ă©mergĂ©. Dans un contexte oĂč la rĂ©alitĂ© virtuelle gagne progressivement une place en travail social, ce mĂ©moire offre des pistes de rĂ©flexion sur les façons de bien lây intĂ©grer et montre que cette technologie, si elle est utilisĂ©e comme un outil complĂ©mentaire aux interventions traditionnelles peut avoir de nombreux bĂ©nĂ©fices tant en prĂ©vention, quâen intervention et en formation

Environmental enteric dysfunction and the fecal microbiota in malawian children
Environmental enteric dysfunction (EED) is often measured with a dual sugar absorption test and implicated as a causative factor in childhood stunting. Disturbances in the gut microbiota are hypothesized to be a mechanism by which EED is exacerbated, although this supposition lacks support. We performed 16S ribosomal RNA gene sequencing of fecal samples from 81 rural Malawian children with varying degrees of EED to determine which bacterial taxa were associated with EED. At the phyla level, Proteobacteria abundance is reduced with severe EED. Among bacterial genera, Megasphaera, Mitsuokella, and Sutterella were higher in EED and Succinivibrio, Klebsiella, and Clostridium_XI were lower in EED. Bacterial diversity did not vary with the extent of EED. Though EED is a condition that is typically believed to affect the proximal small bowel, and our focus was on stool, our data do suggest that there are intraluminal microbial differences that reflect, or plausibly lead to, EED

A RIPE3b1-like factor binds to a novel site in the human insulin promoter in a redox-dependent manner
AbstractIn the human insulin gene, a regulatory sequence upstream of the transcription start site at â229 to â258 (the E2 element) binds a ubiquitous factor USF. The present study led to the identification of a second factor, D0, that binds to an adjacent upstream site, the C2 element, that has previously not been described. The results demonstrate that D0 exhibits similar properties to RIPE3b1, a factor shown to be an important determinant of insulin gene ÎČ-cell-specific expression. Binding of D0 to the C2 element was abolished by the oxidising agent diamide, and the alkylating agent N-ethylmaleimide. The results indicate that expression of the insulin gene may be regulated by a redox-dependent pathway involving RIPE3b1 or a RIPE3b1-like factor
Status Report of the DPHEP Study Group: Towards a Global Effort for Sustainable Data Preservation in High Energy Physics
Data from high-energy physics (HEP) experiments are collected with
significant financial and human effort and are mostly unique. An
inter-experimental study group on HEP data preservation and long-term analysis
was convened as a panel of the International Committee for Future Accelerators
(ICFA). The group was formed by large collider-based experiments and
investigated the technical and organisational aspects of HEP data preservation.
An intermediate report was released in November 2009 addressing the general
issues of data preservation in HEP. This paper includes and extends the
intermediate report. It provides an analysis of the research case for data
preservation and a detailed description of the various projects at experiment,
laboratory and international levels. In addition, the paper provides a concrete
proposal for an international organisation in charge of the data management and
policies in high-energy physics
Observation of a Coherence Length Effect in Exclusive Rho^0 Electroproduction
Exclusive incoherent electroproduction of the rho^0(770) meson from 1H, 2H,
3He, and 14N targets has been studied by the HERMES experiment at squared
four-momentum transfer Q**2>0.4 GeV**2 and positron energy loss nu from 9 to 20
GeV. The ratio of the 14N to 1H cross sections per nucleon, known as the
nuclear transparency, was found to decrease with increasing coherence length of
quark-antiquark fluctuations of the virtual photon. The data provide clear
evidence of the interaction of the quark- antiquark fluctuations with the
nuclear medium.Comment: RevTeX, 5 pages, 3 figure

Prosociality from Early Adolescence to Young Adulthood: A Longitudinal Study of Individuals with a History of Language Impairment
Background: Longitudinal research into the development of prosociality contributes vitally to understanding of individual differences in psychosocial outcomes. Most of the research to date has been concerned with prosocial behaviour in typically developing young people; much less has been directed to the course of development in individuals with developmental disorders.
Aims: This study reports a longitudinal investigation of prosocial behaviour in young people with language impairment (LI), and compares trajectories of development to typically developing age-matched peers (AMPs).
Methods and Procedures: Participants were followed from age 11 years to young adulthood (age 24 years).
Outcomes and Results: Participants with LI perceived themselves as prosocial; their ratings â though lower than those for the AMPs - were well within the normal range and they remained consistently so from 11 to 24 years. Two different developmental trajectories were identified for the LI group, which were stable and differed only in level of prosociality. Approximately one third of participants with LI followed a moderate prosociality trajectory whilst the majority (71%) followed a prosocial trajectory. We found evidence of protective effects of prosociality for social outcomes in young adulthood.
Conclusions and Implications:
The findings indicate that prosociality is an area of relative strength in LI
Three Novel Downstream Promoter Elements Regulate MHC Class I Promoter Activity in Mammalian Cells
BACKGROUND: MHC CLASS I TRANSCRIPTION IS REGULATED BY TWO DISTINCT TYPES OF REGULATORY PATHWAYS: 1) tissue-specific pathways that establish constitutive levels of expression within a given tissue and 2) dynamically modulated pathways that increase or decrease expression within that tissue in response to hormonal or cytokine mediated stimuli. These sets of pathways target distinct upstream regulatory elements, have distinct basal transcription factor requirements, and utilize discrete sets of transcription start sites within an extended core promoter. METHODOLOGY/PRINCIPAL FINDINGS: We studied regulatory elements within the MHC class I promoter by cellular transfection and in vitro transcription assays in HeLa, HeLa/CIITA, and tsBN462 of various promoter constructs. We have identified three novel MHC class I regulatory elements (GLE, DPE-L1 and DPE-L2), located downstream of the major transcription start sites, that contribute to the regulation of both constitutive and activated MHC class I expression. These elements located at the 3' end of the core promoter preferentially regulate the multiple transcription start sites clustered at the 5' end of the core promoter. CONCLUSIONS/SIGNIFICANCE: Three novel downstream elements (GLE, DPE-L1, DPE-L2), located between +1 and +32 bp, regulate both constitutive and activated MHC class I gene expression by selectively increasing usage of transcription start sites clustered at the 5' end of the core promoter upstream of +1 bp. Results indicate that the downstream elements preferentially regulate TAF1-dependent, relative to TAF1-independent, transcription
