Les déterminants de la charge de travail perçue dans deux services d’urgence hospitaliers en France

This article gives an account of research carried out the workload of healthcare providers in hospital emergency wards, by focusing on several factors that are both related to the patients and to their activity. Based on 121 observations conducted in two hospitals, coupled with the NASA-TLX scale and an ad hoc questionnaire, this research indicates that the elements which contribute the most to perceived workload are the agitated behavior of patients and communication difficulties linked to handicap. However, variations in the number of tasks do not seem to have an influence on the workload perceived by health care providers which tends to highlight that the relations to patients contribute more to the perception of workload than the number of tasks. In the situation observed, the regulation of workload is made possible by the management of relational factors (physical demand, frustration and effort) which determine, in part, workload perception. In order to reduce or adapt this load, this article suggests basing interventions on the way to deal with difficult patients and not on the regulation of the number of tasks.     

Perceived cultural distance and acculturation among exchange students in Russia

The relations of perceived cultural distance, personality, acculturation orientations and outcomes were studied among exchange students (N = 187) in Russia who came from various countries in Asia, sub‐Saharan Africa, Latin America and the former Soviet Union. The hypothesis was supported that a larger perceived cultural distance between mainstream and immigrant culture is associated with less psychological (homesickness and stress) and sociocultural (behaviour with Russian students and behaviour with co‐nationals) adjustment. The statistical relations between perceived cultural distance, personality and sociocultural adjustment were much stronger for host domain behaviour than for home domain behaviour. Adjustment was higher for participants with more cultural empathy, openmindedness and flexibility. Adjustment showed statistically stronger associations with cultural distance than with acculturation orientations. It is concluded that cultural distance may be more salient than acculturation orientations in studies of heterogeneous groups of immigrants. Copyright © 2008 John Wiley & Sons, Ltd.     

真实型领导对教师知识分享行为的影响:组织支持感的中介和调节作用*

为了探讨真实型领导、组织支持感和教师知识分享行为的关系,对330个有效教师样本进行研究。结果发现:(1)真实型领导对教师的知识分享行为具有显著的预测作用(β=0.494,p<0.001)。(2)组织支持感在两者之间具有部分中介作用,间接效应占总效应的44.8%。(3)组织支持感在真实型领导的下属导向、领导特质、诚实不欺和正直无私与知识分享行为的关系中起调节作用,但在循规蹈矩与知识分享行为的关系中的调节作用不显著。     

不同性别比和童年经济状况对未婚男性性态度的影响

基于进化心理学的生命史理论,通过两个实验探讨性别比和童年经济状况同男性性态度间的关系。实验1和实验2分别采用图片和文字材料启动被试的性别比感知,结果发现感知性别比和童年经济状况对未婚男性的"随意性行为"态度表现出显著的交互效应：童年家庭经济状况差的未婚男性在感知到周围女性数量相对充裕的情境下,其性开放态度会较感知到周围男性数量充裕时明显上升;童年家庭富裕的男性的性开放态度在不同感知性别比下保持相对稳定。     

个体和群体歧视知觉对流动儿童主观幸福感的影响

采用整班联系、自愿参加的方式,通过匿名方式对北京市1552名流动儿童施测个体和群体歧视知觉问卷、积极/消极情感量表、生活满意度量表、内群体认同测验与群体地位感测验,探讨个体和群体歧视知觉对流动儿童主观幸福感的影响及内群体认同感和群体地位感在其中的中介作用。结果表明：（1）个体和群体歧视知觉与流动儿童的主观幸福感、内群体情感认同及群体地位感之间存在显著性相关,与内群体认知认同之间相关不显著。（2）个体歧视知觉对流动儿童的主观幸福感存在直接显著的负向预测作用,并通过降低流动儿童的群体地位感,进而间接地负向影响流动儿童的主观幸福感;（3）群体歧视知觉对流动儿童的主观幸福感也存在直接显著的消极影响,并同时借助于群体地位感的中介作用、以及内群体情感认同和群体地位感的双重中介作用间接地降低流动儿童的主观幸福感。     

心理委员胜任力与心理健康的关系:领悟社会支持和心理弹性的链式中介

目的:探究领悟社会支持和心理弹性在心理委员胜任力与心理健康之间的中介作用。方法:采用问卷调查法对某高校433名大学生进行测查。结果表明:(1)相关分析显示,心理委员胜任力与领悟社会支持、心理弹性呈现显著正相关,与大学生心理健康呈现显著负相关;(2)结构方程模型分析表明,心理委员胜任力对大学生心理健康的直接效应显著,领悟社会支持和心理弹性在心理委员胜任力与大学生心理健康之间中介作用均显著,且领悟社会支持-心理弹性的链式中介作用也显著。结论:心理委员胜任力既可以直接预测大学生心理健康,又可以分别通过领悟社会支持、心理弹性的中介作用,以及领悟社会支持-心理弹性的链式中介作用间接预测大学生心理健康。     

中学生成就目标相关因素的发展研究

探索了影响中学生成就目标各因素间的相互关系及其对学业成绩的影响,并就此提出一个中学生学业活动的简洁模式。(1)中学生的认知参与和能力知觉、成就目标之间极显著正相关,学业焦虑和认知参与、能力知觉、成就目标之间显著负相关;两成就目标间的相关不显著;(2)能力知觉、认知参与、学业焦虑是学业成绩的有效预测因子。     

Narrowing the Creativity Gap: The Moderating Effects of Perceived Support for Creativity

This article examines the role of 3 types of perceived support for creativity in moderating the relation between creative self-efficacy and self-perceived creativity. The findings suggest significant interaction effects for perceived work-group support and supervisor support, but not for perceived organizational support. This study is among the first to (a) examine the importance of perceived support for creativity in unlocking creative potential and increasing creativity in organizations and (b) use interaction terms in structural equation modeling (SEM) to investigate moderator effects in an applied research setting. These results imply that organizational interventions focused on training supervisors and work-group members to support creativity in the workplace may be more effective than broader and less focused interventions at the organizational level.     

感知环境不确定性与环境扫描对认知变化的影响——认知闭合需要与认知需要的调节作用

对426名大学生进行问卷调查,考察了感知环境不确定性对认知变化的影响,环境扫描行为的中介作用以及认知闭合需要与认知需要对两阶段中介模型的调节作用。结果发现：（1）感知环境不确定性能够正向预测认知变化水平,并且环境扫描行为的两个维度都起到中介作用;（2）认知闭合需要能够负向调节中介模型的前后两个阶段;（3）认知需要对环境扫描有直接正向作用,并且对关注程度的促进更大,但是负向调节扫描频率和认知变化之间的关系。     

领悟社会支持、应对效能和压力性生活事件对青少年学业成就的影响机制

为揭示领悟社会支持与青少年学业成就的关系,以及应对效能的中介效应和压力性生活事件的调节效应,采用领悟社会支持问卷、应对效能问卷、压力性生活事件量表和学业成就问卷对1687名青少年进行研究。结果显示：（1）领悟社会支持能够促进青少年的学业成就;（2）应对效能对领悟社会支持与学业成就的关系具有中介效应;（3）压力性生活事件能够调节应对效能的中介作用。因此,领悟社会支持对学业成就的影响是有调节的中介效应。
