A nonrecursive model with relationships between perceived lack of social support, perceived self-efficacy in eliciting support at the workplace, and the 3 successive burnout dimensions–emotional exhaustion, depersonalization, and personal accomplishment–was tested in a sample of 277 secondary-school teachers in The Netherlands. Results showed that teachers' perceived lack of support from colleagues and principals had a significant effect on their self-efficacy beliefs in eliciting support from them, while these self-efficacy beliefs were shown to predict their level of burnout. The hypothesized feedback loop was also confirmed: Teachers' level of burnout predicted the extent to which they feel lack of support. An additional effect of the personal-accomplishment dimension of burnout on perceived self-efficacy was suggested. It was concluded that perceived self-efficacy in eliciting support at the workplace is a usable construct in the prediction of teacher burnout. Future directions in research are suggested.  相似文献

Livestock production has been confronted with several epidemics over the last decades. The morality of common animal disease strategies—stamping out and vaccination—is being debated and provokes controversies among farmers, authorities and the broader public. Given the complexity and controversy of choosing an appropriate control strategy, this article explores the potential of nano-enabled diagnostics in future livestock production. At first glance, these applications offer promising opportunities for better animal disease surveillance. By significantly shortening the reaction time from diagnosis to appropriate control, they could complement the current disease management strategies. Although nano-enabled diagnostics will not make livestock disease eradication strategies redundant or completely free of the culling of infected animals, these diagnostics could significantly reduce the number of culled animals and animal suffering. This article aims to demonstrate that the ethical assessment of advanced diagnostics can build on the experiences with decision making in biomedical ethics where nonmaleficence, beneficence, autonomy and justice serve as important benchmarks. Nano-enabled diagnostics may be an ethically sound solution if it can resolve the dilemma between stamping out and vaccination in favor of the latter and if it can balance the autonomy–paternalism dilemma between farmers and authorities. The technology should allow to be switched on and off by farmers, whilst simultaneously allowing for a weak paternalism on behalf of authorities in order to benefit the farmer and broader society and to protect them from harm.

A social identity approach to the investigation of group-based reactions to a merger is outlined, in which a merger is analyzed in terms of the continuation or change of the pre-merger group identity. In two experiments, the relationship between pre-merger identification, post-merger identification, and ingroup bias was investigated using a minimal group paradigm. Results from both studies showed that the perceived continuation of the pre-merger group identity in the post-merger group strengthened the positive relationship between pre-merger identification and identification with the superordinate post-merger group. Moreover, perceived continuation strengthened, rather than reduced, ingroup bias at the subordinate level of the merged groups. Some theoretical and practical implications are discussed.  相似文献

The central objective of this study was to investigate the role of social appraisal in sex differences in anger expression. Anger expression was inferred from the amount of hot sauce given to the person who induced anger. Participants were randomly assigned to a social condition, in which they expected to meet this person, or to a nonsocial condition, in which they had no such expectation. Men and women differed in their anger expressions, despite the fact that they did not differ in anger experience. Women expressed anger to a lesser extent than men, but only in the social condition. Social appraisal partly mediated the relation between sex and anger expression. The role of social appraisal in emotion and appraisal theory is discussed.  相似文献

The authors propose that people have difficulty managing conflict because they quickly develop ownership of arguments and positions they use in the dispute, that these arguments and positions become part of their (extended) self-concept, and that any opposition or counterargumentation therefore becomes an ego-threat. Four studies reveal that individuals value arguments and beliefs more when these are associated with the self and that anticipated or real opposition triggers ego-defensive cognition and behavior, including competitive communication, retaliatory responses, negative perceptions of the partner, and attitude polarization. These effects were weaker when epistemic needs were raised through process accountability or when individuals had high rather than low self-concept clarity. The authors conclude that because people develop ownership of arguments and make these part of their self-concept, conflict is difficult to manage and bound to escalate.  相似文献

The present research examined the effect of leaders' procedural fairness and perceived charisma on an important organizational process: cooperation. Both charisma and procedural fairness were predicted to have a positive effect on cooperation, and procedural fairness and charisma were predicted to interact such that their effects are stronger alone than in conjunction. Results from a scenario experiment, a cross-sectional survey, and a laboratory experiment supported these predictions. Results from the laboratory study also showed that the interactive effect of leader charisma and procedural fairness on cooperation was mediated by their interactive effect on the sense of group belongingness. It is concluded that leader charisma and procedural fairness may engender cooperation because they appeal to relational concerns.  相似文献

A review is given of scores on various cognitive measures, comparing groups of ethnic Dutch and non‐Western immigrants using a large number of datasets. The research shows that there are large group differences in school results, work proficiency, and g for Turks, Moroccans, Surinamese, Netherlands Antilleans, and Indonesians from the Moluccans compared with ethnic Dutch. However, South‐East Asians score higher, and persons with one immigrant and one ethnic Dutch parent score only slightly below the mean of the Dutch. When comparing first‐generation disadvantaged immigrant groups with later generations the data show substantial improvements for g, a remarkable stability of educational differences for younger children, and a clear improvement in educational achievement at the end of primary school. Indirect data on intergenerational improvements in work proficiency appear suggestive of a trend of closing gaps. Some of the data reflect higher cognitive capacities over time, and this enhances integration of immigrants into Dutch society. Causes of group differences and improvements in mean level of g are discussed. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

This article is about research with a group of young refugee men from Sudan and their relationship to football (soccer) as they resettle in Australia. It provides evidence of the resilience, independence and autonomy that such young refugees possess and what these young men's intimate knowledge of these qualities can teach us. In other words, how can we as researchers learn from these young refugees about how they perform these qualities and how may we accommodate this during ethnographic research and in sports-based intervention programs aimed at empowering such young people? Further, the article explores the role of intimacy in this process by accounting for the role of affective connections on and off the sporting field. The argument is that intimacy can help those involved negotiate the power inequities present in sports-based intervention programs and in associated research.  相似文献

Are women less interested in becoming professors than men? We applied the theory of planned behavior (TPB) to investigate the intention to pursue an academic career. Postdocs who recently finished their PhD at a German university participated in an online survey (N = 380, mean age: 33; 45% women). Women reported lower academic career intentions (d = 0.40); TPB variables (attitude, subjective norm, self‐efficacy) explained 87% of this gender difference. At an 8 month follow‐up, we found no gender difference in the intention to continue in an academic career among the postdocs who were still working in academia (n = 129). Addressing TPB constructs early in women's academic careers could encourage them to remain in academia and strive for a professorship.  相似文献
