It is unclear whether individuals searching the Internet for assistance with thoughts of suicide are likely to encounter predominantly helpful or harmful resources. This study investigated websites retrieved by searching Google for information and support for suicidal thoughts. Google searches retrieved a high percentage of irrelevant websites (26%, n = 136). Of the 329 relevant websites retrieved, the majority were suicide preventive (68%); however, a considerable proportion of sites expressed mixed (22%) or neutral (8%) suicide attitudes, and 1% were explicitly pro‐suicide. The results highlight a need for suicide prevention organization websites to be made more easily accessible. In the meantime, clinicians should be aware of appropriate websites to recommend to clients.  相似文献

No recent survey documents assessment center (AC) practices across several countries. Therefore, we analyse AC practices in a sample of 97 organisations from nine countries in Western Europe and North America. We report findings regarding job analysis, dimensions, exercises, additional diagnostic methods, use of technology, assessor characteristics, contents and methods of assessor training, observational systems, information provided to participants, evaluation of participants' reactions, data integration, characteristics of feedback, and features after the AC. Finally, we compare our results with prior findings to identify trends over time and point out features of ACs that could be improved.
Face aux défis que soulèvent les centres d'évaluation (AC) dans les organisations internationales, nous proposons un modèle qui rend compte des variations transculturelles dans ces pratiques, variations relevant de données individuelles (la motivation et la qualification des experts en resources humaines), de conditions culturelles (le « contrôle de l'incertitude >> et la « distance hiérarchique >>) et de réalités institutionnelles (des differences dans le niveau officiel de collectivisme et des divergences en ce qui concerne les normes légales et les lois régissant l'emploi). Ce modèle est exploité pour expliquer les différences dans la planification, l'exécution et l'évaluation des AC dans des organisations situées dans neuf pays d'Europe de l'ouest et d'Amérique du nord. Nous mettons aussi en evidence des tendances sur le long terme dans les pratiques des AC et discutons de l'amélioration de ces pratiques et de l'orientation des futures recherches dans ce domaine.  相似文献

In some circumstances, children of 5 produce identical classifications to 10 year olds when asked to sort a collection of objects. This has been interpreted as meaning that the process of constructing classifications is very similar at 5 and 10 years. But this conclusion rests on a comparison of the product of children's sortings, rather than on a study of their activity in producing sortings. The present paper argues that the process of classifying is in fact very different for 5 and 10 year olds: whereas the older children treat the whole classification as a single unit composed of interrelated classes, the younger children proceed as though each class were independent of the others. At around 7 years, there is evidence for a transitional phase, in which children directly work on the relations between classes and so organize their initially “juxtaposed” procedures into more coherent systems. The tendency to work on the relations between elements in the process of classifying is not, however, simply an age-related phenomenon: evidence for a similar effect can be observed in children throughout the age range of 5 to 10 years, during the course of short experimental sessions. Furthermore, the effect is not merely a response to errors or difficulties: the tendency to work on classifying relations can be seen in 5-year-old children in a task in which they are already successful. It seems that children spontaneously discover and use information about their procedures and the relations between them. This process is an end in itself. It occurs whether or not its results yield more successful performance. The approach taken in this paper is not confined to one area of behavior. This analysis of children's classifying fits closely with work in a very different domain, i.e. Karmiloff-Smith's work on children's language and other representational systems. The analysis has implications for computer models of skill acquisition, as well as for psychological theories of development.  相似文献
