Teacher stress and guidance work in Hong Kong secondary school teachers   总被引:2,自引:0,他引:2  
Major sources of stress in Hong Kong teachers were investigated, with specific reference to guidance work as a potential source of stress. A survey of 415 secondary school teachers revealed that guidance-related aspects of work constituted a major dimension of stress, with guidance teachers, female teachers, younger teachers and junior teachers perceiving more stress than their counterparts in this dimension. Workload and time pressure were perceived as the most stressful aspects of work for all teachers. Results also showed an association between stress and job satisfaction, and biographical variables. Implications of the findings for teachers doing guidance work in Hong Kong and internationally are discussed.  相似文献

This is the first study to examine the relations between components of masculine gender role conflict and specific symptoms of psychological distress in a sample of men seeking counseling services. One hundred and thirty male clients from 2 university counseling centers completed the Gender Role Conflict Scale and the Symptom Checklist-90-Revised. Participants reported moderate to high levels of psychological symptoms, which were correlated with components of masculine role conflict. Results of simultaneous multiple regressions supported previous findings in nonclinical samples of relations between masculine role conflict and depression and interpersonal issues. In addition, masculine role conflict significantly predicted paranoia, psychoticism, and obsessive compulsivity. Implications for counseling and future research are discussed.  相似文献

In a series of three experiments, subjects made risky decisions under conditions of hypothetical or real consequences. Task variations across experiments included: (1) type of risk (monetary gambles or investments of time and effort), (2) within-subject and between-subjects manipulations of consequence condition, and (3) single or multiple decisions. The hypothesis of no difference between choices in real and hypothetical consequence conditions was retained in each experiment. Supplemental analyses ruled out various “artifactual” interpretations of the null results. Discussion focused on conditions in which researchers can and cannot infer decision makers’ actual risk preferences from their responses in laboratory tasks.  相似文献

Mental models of the earth, sun, and moon: Indian children's cosmologies   总被引:1,自引:0,他引:1  
This study reports data on the acquisition of knowledge about astronomy in children from India. Based on prior research, we hypothesized that the cosmological models that children construct are influenced by both first-order and second-order constraints on knowledge acquisition. First-order constraints are the implicit assumptions that govern the construction of initial cosmological models. Examples of such constraints include the assumptions that the earth is flat and supported. Such first-order constraints are presumed to be universal. Second-order constraints arise from the specific properties ascribed to cosmological objects. For example, representations of the earth's shape and location relative to the sun and moon constrain the kinds of mechanisms that are generated to account for the day-night cycle. We hypothesized that in cultures where both folk cosmologies and the scientific cosmological model are accessible to children, aspects of folk models are likely to be incorporated in children's cosmologies if they provide a psychologically easier way of satisfying first-order constraints. This hypothesis is supported by our findings with regard to universality and culture specificity in children's cosmologies. Indian children's cosmologies honor a variety of universal first-order constraints. These include constraints on the shape of the earth (e.g., support and flatness) and on the relative locations and motions of objects in the cosmology (e.g., continuity). However, many Indian children borrow the idea that the earth is supported by an ocean or a body of water from folk cosmology. This solution to the support constraint on the shape of the earth is not found in American children's initial cosmologies.  相似文献

During the early centuries of Islam, the Bible did not usually receive specific attention from Muslim polemicists. Among those who did refer to it, some rejected the text on the grounds that it was corrupt, and developed accounts of how the original injil had been lost and replaced by the canonical Gospels. The majority, however, have left no expressed view, but do not appear to have experienced difficulty in employing suitable verses in their arguments as illustrations and proofs. A few scholars were in a position to use the Biblical texts to good effect in their arguments. The Christian convert cAli b. Rabban al‐Tabari employed a distinctively Muslim method of exegesis, and demonstrated how predictions of the coming of Muhammad and Islam are scattered throughout the biblical books. The Zaydi theologian al‐Qasim ibn Ibrahim al‐Rassi followed a more radical method in translating parts of Matthew's Gospel into Arabic, and altering words and phrases and omitting sections in order to make the original conform to Islamic beliefs. This Islamicization of the Gospel is symptomatic of the confident early third/ninth‐century belief that Islam provided the criteria for true teachings.  相似文献

Participants (N= 212) rated the fairness, job relevance, appropriateness, and invasiveness of 16 tests that could be used to select or promote people into production or management positions. Fairness, job relevance and appropriateness were highly correlated, and were combined to form a composite evaluation scale. Evaluations and invasiveness ratings varied among the 16 tests, with the most positive ratings given to interviews and work samples and the most negative ratings given to astrology, graphology and polygraphs. Evaluations of four tests were affected by the position (manager vs. production worker). Evaluations of 11 tests and invasiveness ratings of two tests were affected by respondent experience with the test. Respondents who had experienced the tests evaluated them more positively and considered them to entail a smaller invasion of privacy. Responses were not affected by whether the test was to be used for selection versus promotion decisions.  相似文献

In the August 1993 issue ofJournal of Applied Psychology, Deniz Ones, Vish Viswesvaran, and Frank Schmidt published a monograph on the validity of integrity tests as revealed by meta-analysis. They concluded that integrity tests have substantial and generalizable predictive validity for criteria of both overall job performance and counterproductive behaviors on the job (e.g., disciplinary problems, absenteeism, rule breaking, violence on the job, theft, etc.). During the Fall of 1992, the authors sent a preprint of this study to David Lykken of the University of Minnesota, stimulating the exchange of letters that is reproduced here. The doubts, concerns, and feelings about integrity tests expressed by Professor Lykken are likely to be shared by others. The responses by Professors Schmidt, Ones, and Viswesvaran attempt to show that these worries are unfounded.  相似文献
