Le rôle modérateur des orientations vers les objectifs dans la relation entre l’envergure de poste et l’engagement organisationnel

This paper examines the moderating role of goal orientations (learning, performance and avoidance orientation) in the relationship between job scope (i.e., a composite measure capturing task variety, autonomy, feedback and significance) and organizational commitment. Based on a sample of 314 participants, the analyses indicate that job scope is positively related to commitment and that performance orientation and avoidance orientation act as negative moderators of job scope. Specifically, job scope was more strongly related to commitment at low levels of these traits. We discuss the importance of considering the role of employee personality in the study of the effect of work context on commitment.     

The effects of task instructor status on prospective memory performance in preschoolers

The present study applied a 2 × 2 experimental design to assess prospective memory (PM) development across preschool age and to examine the effect of task instructor status (researcher vs. significant other) on PM performance in 80 preschool children. Participants were required to name pictures (ongoing task [OT]), and to remember to refrain from naming but instead give a different response to certain target cues (PM task). Although the OT was of comparable difficulty for both age groups (as indicated by no performance differences), results still indicated significantly higher PM performance in 5-year-olds than in 3-year-olds, confirming the age-related increase of PM capacities between 3 and 5 years. Furthermore, results showed a performance-enhancing effect of significant others as task instructors on both age-groups. Post-hoc analysis revealed that 3-year-olds instructed by a significant other still performed marginally worse than 5-year-olds instructed by a researcher, underlining the finding that substantial changes of PM capacities take place during early childhood.     

工作家庭两不误为何这么难？基于工作家庭边界理论的探讨

为探讨工作家庭冲突对员工工作态度和行为倾向的影响, 以国内某大型制造企业集团位于北京、杭州、西安等地7家分公司的545名员工为样本, 采取问卷调查法在两个不同时段获取数据, 考察了角色压力(角色冲突、角色模糊和角色超载)在工作干涉家庭和家庭干涉工作这两种对偶冲突模式与员工工作满意度和离职意向之间的中介作用机制。结果显示：角色压力在工作家庭冲突与工作满意度和离职意向之间起到完全中介作用, 工作满意度在角色压力和离职意向之间起到部分中介作用。结论有助于分析工作家庭冲突的深层原因并采取恰当的干预策略, 降低工作家庭冲突对员工工作态度和行为倾向的负面影响。     

Actions taken by schools when tobacco policies are violated: associations with adolescent smoking prevalence

This study examined the association of adolescent smoking prevalence with actions taken by schools (i.e., informing parents or disciplining pupils at school) for violating the school tobacco policy. Interaction terms between actions taken by schools and role models' smoking behavior or support for adolescents were also examined. Data were collected using self-completed questionnaires from a nationally representative Norwegian sample of 15-year-olds (1,404 pupils, 51% males) and 73 staff members. Informing parents when the school tobacco policy was violated by contrast with other actions taken by schools was not associated with lower levels of adolescent smoking. Disciplining pupils was associated with lower levels of adolescent smoking but the association was no longer significant when examined together with parents' and teachers' smoking behavior or support. Exposure to parents' and teachers' smoking, and teachers' support were associated with adolescent smoking prevalence, irrespective of actions taken by schools. Identifying the mechanism under which these different home and school factors relate to adolescent smoking may be worthwhile to inform intervention initiatives.     

Basic Personal Values and the Meaning of Left‐Right Political Orientations in 20 Countries

This study used basic personal values to elucidate the motivational meanings of “left” and “right” political orientations in 20 representative national samples from the European Social Survey (2002–2003). It also compared the importance of personal values and sociodemographic variables as determinants of political orientation. Hypotheses drew on the different histories, prevailing culture, and socioeconomic level of three sets of countries—liberal, traditional, and postcommunist. As hypothesized, universalism and benevolence values explained a left orientation in both liberal and traditional countries and conformity and tradition values explained a right orientation; values had little explanatory power in postcommunist countries. Values predicted political orientation more strongly than sociodemographic variables in liberal countries, more weakly in postcommunist countries, and about equally in traditional countries.     

Perceived Conflict and Leader Dominance: Individual and Contextual Factors Behind Preferences for Dominant Leaders

Recent research finds that political candidates and leaders with dominant, masculine physical features are more preferred under conditions of conflict than of cooperation. Importantly, however, methodological limitations of past research have hindered the identification of whether this effect reflects that voters intuitively view (1) dominant leaders as more competent in solving problems of conflict, (2) nondominant leaders as more competent in solving problems of cooperation, or (3) both. In this article, we utilize recent advances in evolutionary psychology to form precise predictions on the nature of the underlying psychology and employ an unprecedented array of data types—including highly controlled experiments, natural experiments, and behavioral measures—to investigate the validity of these predictions. Using large approximately nationally representative surveys of 2,009 Poles and Ukrainians fielded during the Crimea crisis in 2014, we find that preferences for leader dominance are exclusively driven by the intuition that dominant leaders are better able to facilitate aggressive responses during social conflict and that these preferences are regulated by contextual conditions and individual predispositions related to such responses.     

The family as its own reflecting team: a family therapy method

Social research has suggested that people, in general, tend to overestimate their skills and abilities. Interestingly, research has found that peers are better predictors of a person's behaviour than self‐assessment, suggesting that others know us better than we know ourselves. Family therapists should be aware that family members might not give accurate accounts of themselves. In order to overcome this problem, therapists should incorporate peer assessments into therapy. Reflecting teams and videotaping do incorporate peer assessments, yet these methods can be impractical. This article describes a method of family therapy using enactments as a means of setting up the family as its own reflecting team. The method suggests that the family and therapist switch roles several times during the enactment, and then encourages a discussion on the peer observations on how each person addresses a problem in the family. Case examples illustrate how feedback from peers promotes insights.     

农村留守儿童的抑郁和反社会行为:日常积极事件的保护作用

以来自河南省农村的410名农村留守儿童(双亲外出和单亲外出)和非留守儿童为被试,考察了日常烦恼这一危险因素与儿童抑郁、反社会行为的关系,并探讨了日常积极事件在其中的保护作用。结果表明,儿童经历的日常烦恼越多,其抑郁和反社会行为水平越高。日常积极事件表现出了对儿童抑郁和反社会行为的改善效应,但是因儿童留守类别的不同而不同:日常积极事件对单亲外出儿童和非留守儿童抑郁的改善效应较强,对双亲外出儿童反社会行为的改善效应较强。此外,日常积极事件还可以有效抵抗日常烦恼对儿童反社会行为的不利影响。     

热休克蛋白7O在动脉粥样硬化发病中的双重作用

大多研究表明,热休克蛋白70通过抗凋亡、抗氧化及抗炎症反应而在动脉粥样硬化发病中起保护作用。但亦有研究表明,热休克蛋白70通过促凋亡、促进炎症反应而在动脉粥样硬化的发生发展中起促进作用。说明热休克蛋白70在动脉粥样硬化发病中有双重作用,进行基础研究和临床干预时应考虑到其双面性。
