This article presents a case study in a savings bank in which a change of managerial culture is conducted over several years. A survey feedback was carried out where special attention was paid to subordinates' perceptions on managerial behaviours of the immediate manager. This intervention intended to stimulate and facilitate changes of managers' values, competences, and practices by means of providing them with relevant feedback from subordinates and by developing a team-centred process of climate analysis and change. However, perceptions and interpretations developed by managers and their subordinates about the actions undertaken emphasized political processes and power games, which caused emotional reactions such as fear, suspiciousness, and discomfort. In light of this situation, the aims, meaning, and process of the intervention, as understood and interpreted by the participants, were taken as the focus of a subsequent target of analysis and intervention. Information obtained on participants' views and the process of their deconstruction are presented. Some suggestions are made to improve professional practice, and research questions are raised that should be incorporated into the research agenda in the near future.  相似文献

This study is one of the first studies to approach workplace bullying cross-culturally. It sought to compare employees' understanding of workplace bullying in two different world regions: Central America and Southern Europe, regarding three aspects of workplace bullying: psychological vs. physical harassment, hierarchical vs. horizontal bullying, and direct vs. indirect aggression. A convenience sample of 246 workers provided their own definition of workplace bullying through a single, open-ended question. The results showed that employees from Central America emphasized the physical component of workplace bullying more than the Southern European employees. However, similarities in the conceptualization of workplace bullying across both cultures were found as well. Both Southern European and Central American employees defined workplace bullying mainly as a hierarchical phenomenon, where the aggression took the form of direct strategies. Such differences and similarities bring to the field some positive inputs for the development and implementation of different strategies for dealing effectively with this phenomenon.  相似文献

Three experiments examined the role of visual feedback on the performance of a fine motor task, namely the rotary pursuit, in patients with Alzheimer's disease (AD) and healthy older adults. After extensive practice tracking a fully visible target, participants in Experiments 1 and 2 were tested under restricted vision (RV) conditions. In both experiments, the two groups showed a drop in performance when vision was restricted, with AD patients showing a significantly larger decline. Tracking improved significantly in normal controls, but not AD patients across the RV trials after the initial drop. When difficulty of the rotary pursuit task was manipulated in Experiment 3 without restricting vision, AD patients and normal controls showed identical patterns of performance. Consequently, it could be concluded that AD patients in the first two experiments were relying more heavily on visual information for accurate performance of the tracking task than their healthy peers.  相似文献

We predicted that an expectancy of acquiring a feared fat self and an expectancy of acquiring a hoped-for thin self both mediate the impact of body size on women's body esteem. We also predicted that the mediating pathway through the feared fat self would be stronger than that through the hoped-for thin self. A community sample of 251 women reported their age, height, weight, and completed measures of body esteem and expectancy perceptions of acquiring the feared fat and hoped-for thin selves. Bayesian Structural Equation Modeling (SEM) demonstrated that expectancies about the feared fat self and about the hoped-for thin self mediated the relationship between body size and body esteem. Bayesian SEM also revealed that the pathway through the feared fat self was stronger than that through the hoped-for thin self. Implications for future research and the development of eating pathology are discussed.  相似文献

Decision making requires the recruitment of several cognitive processes. So far, however, few studies have dealt with the role of inhibitory control in this domain. In this study, we aim to examine this issue in a memory-based decision task by using an adaptation of the retrieval practice paradigm (Anderson, Bjork, & Bjork, 1994 Anderson, M. C., Bjork, R. A. and Bjork, E. L. 1994. Remembering can cause forgetting: Retrieval dynamics in long-term memory. Journal of Experimental Psychology: Learning, Memory, and Cognition, 20: 10631087. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). The retrieval-induced forgetting found through this task is normally explained in terms of inhibition. Specifically, we analyse how retrieval practice may affect what alternatives are selected as well as the choice probability and attribute recall. Our data show a relation between the recall impairment of the attributes due to retrieval practice and biased decisions.  相似文献

The performance of young and adult capuchin monkeys (Cebus apella) on a Concurrent Discrimination Learning (CDL) test and a Delayed Non-Matching to Sample (DNMS) task were investigated. Results indicate that all subjects were able to learn the CDL test with 20-pairs simultaneously and retain this stimulus/reward association within 24-h interval. In contrast, young subjects did not perform the DNMS task with the same proficiency as adults. While adults' scores were above chance across all memory test delays, the young capuchin monkeys performed the test by chance level. These results support the hypothesis that these two tasks require different cognitive processes mediated by two independent neural systems with a differentiated ontogenetic development. Moreover, they provide evidence that this dissociation occurs not only in humans and Old World monkeys but also in the New World capuchin monkeys indicating that this species can be a valuable alternative model for investigations of the neurobiological basis of memory.  相似文献

This study makes a theoretical contribution to stress process research by using a systemic approach to contextualize individual outcomes within the framework of other family members' experience. Utilizing a mixed model approach, indicators of the stress process of urban low-income HIV(+) African American recent mothers were found to affect the psychological distress and perceived adequacy of coping of multiple other family members. These relationships were found to be strongest proximal to birth and to be exacerbated by HIV infection. Social support to the mother was found to have differential effects depending on whether it was from the immediate family or outside sources. HIV infection of the recent mother was found to affect family members both through relationships of the mother's stress process and through their own coping responses.  相似文献
