A survey was conducted using a convenient sample of employees (N = 999) from various industries to examine the main and combined effects of organizational and individual values on organizational commitment, perceived organizational support, and procedural justice. Moderated multiple regression analyses showed that employees' reactions were mainly explained by perceived organizational values and value preferences. In contrast, person-organization value fit and interaction effects were marginal. The implications of these findings are discussed.  相似文献

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

Coping is related to mental and physical health outcomes, but cultural and societal differences may influence its nature and structure. This study reports on the adaptation of the Coping Responses Inventory for Adult (CRI-A) to the Iranian social and cultural context. Study 1 was designed to obtain qualitative data and test the construct and discriminative validity of coping scales. Factor analysis of the CRI and Iranian items yielded seven factors: Religious Coping, Problem Solving, Cognitive Avoidance, Positive Reappraisal, Seeking Guidance and Support, Seeking Alternative Rewards, and Acceptance/Resignation. Internally, consistencies varied considerably from 0.92 to 0.53. All sub-scales from the Coping Responses Inventory for Adult (CRI-A) were resistant to social desirability biases with the exception of Religious Coping and Problem Solving. In Study 2, the replicability of the adapted CRI-A factorial structure and concurrent validity for the newly developed religious coping sub-scale was demonstrated. Given the importance of the role of religious coping in health and well-being outcomes, the expression and use of which may be substantially influenced by cultural practices and norms, it is recommended that future research pursues the validation of context-specific constructs of religious and spiritual coping.  相似文献

The aim of this study was to investigate the accuracy of the Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in detecting and differentiating early stage subcortical vascular dementia (SVD) from early stage Alzheimer’s disease (AD). Ninety-two subjects (18 SVD patients, 36 AD patients, and 38 healthy controls) were assessed using the ACE-R. Between-group’s differences were evaluated using the Quade’s rank analysis of covariance. The diagnostic accuracy and discriminatory ability of the ACE-R were examined via receiver operating characteristic (ROC) analysis. The ACE-R was able to successfully discriminate between patients and healthy subjects. The mean ACE-R total scores differed between SVD and AD patients; there were also significant differences in attention and orientation and in memory measures between the groups. An optimal cut-off of 72/73 was found for the detection of AD (sensitivity: 97%; specificity: 92%) and SVD (sensitivity: 100%; specificity: 92%).  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

Abstract

The performance of English and Spanish subjects was examined in two experiments using a lexical decision task in which the effects of semantic priming and stimulus degradation were systematically varied. The Orthographic Depth Hypothesis predicts that priming and degradation will interact in the orthographically “deep” language (English) but not in the “shallow” one (Spanish). In the first experiment, the two factors were found to interact in a similar way in both English and Spanish groups. In the second experiment, in which only Spanish subjects participated, the interaction was again present but only in those subjects who showed an overall facilitation effect on primed words. The results are consistent with the use of the so-called “direct” route in Spanish and are at variance with other previous findings which have suggested that reading in shallow orthographies occurs via the “indirect” phonological route. There was also evidence that nonword rejection times were slower in Spanish subjects and that the performance of the two groups was affected differently by the different types of neutral baseline primes (asterisks or unrelated words). Possible interpretations of these performance variations are briefly discussed.  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

Twenty neonates of depressed and nondepressed mothers failed to show an initial visual preference for their mother's versus a female stranger's face/voice. Subsequently, infants were habituated to their mother's face and voice. Infants of depressed mothers required 1/3 more trials and almost twice as long to habituate. A posthabituation test with their mother and a different female stranger revealed a preference for the stranger's face for 9 out of the 10 newborns of the nondepressed mothers. Again, the infants of depressed mothers displayed no visual preference. These findings reveal differences in depressed mothers newborns' speed of habituation and face/voice preferences. ©2002 Michigan Association for Infant Mental Health.  相似文献
