This article is based on the results of a survey carried out in 2019 to document health managers and professionals’ knowledge concerning their linguistic obligations and the tools promoting active offer in the field of mental health in French, in Ontario and Manitoba. The working hypothesis is that knowledge of the obligations and available tools can contribute to a successful offer of services in French. The more professionals and managers understand their obligations, the more tools they can use to fulfill them. The study shows that there is indeed a link between knowledge of obligations and the use of tools to provide an active offer of mental health services in French. It also highlights the key role of tools to provide French services actively.  相似文献

Community, demographic, familial, and personal risk factors of childhood depressive symptoms were examined from an ecological theoretical approach using hierarchical linear modeling. Individual-level data were collected from an ethnically diverse (73% African-American) community sample of 197 children and their parents; community-level data were obtained from the U.S. Census regarding rates of community poverty and unemployment in participants’ neighborhoods. Results indicated that high rates of community poverty and unemployment, children’s depressive attributional style, and low levels of self-perceived competence predict children’s depressive symptoms, even after accounting for demographic and familial risk factors, such as parental education and negative parenting behaviors. The effect of negative parenting behaviors on depressive symptoms was partially mediated by personal variables like children’s self-perceived competence. Recommendations for future research, intervention and prevention programs are discussed.

This article argues that an Islamist militant group with a relatively homogenous ethnic make-up is more likely to be supported by those of the same ethnicity even if the group makes no reference to and even downplays the importance of ethnicity. Using survey data from an original survey carried out in Pakistan in 2013, with 7,656 respondents, this hypothesis is tested in a multiple regression analysis of support for the Pakistani Taliban. The results demonstrate that co-ethnicity between the respondent and the Islamist militant group is the most important predictor of support for the militant group.  相似文献

This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks.  相似文献
