Job stress, perceived social support, coping self-efficacy, and coping strategies were studied as predictors of emotional exhaustion and reduced personal accomplishment among a sample of 123 female shelter workers. Overall, these workers did not meet the collective criteria for burnout as defined by Maslach and Jackson (1986) and perceived social support and coping strategies did not account for unique variance in the prediction of emotional exhaustion and reduced personal accomplishment. Rather, high levels of time pressure and low levels of self-efficacy for being productive at work were identified as predictors of emotional exhaustion. Personal accomplishment was predicted by time pressure and robust levels of self-efficacy for dealing with stressors at work. An earlier version of this paper was presented at the 109th annual convention of the American Psychological Association. This paper is based on the Masters thesis of Lisa M. Baker and the undergraduate honors thesis of Nazish Salahuddin, both completed under the direction of Karen M. O’Brien. Gratitude is extended to Christel Nichols and to the crisis workers who participated in this study.  相似文献

This article advances a way of conceptualizing the adolescent as theorist derived from interpretive sociology. This formulation of the adolescent as theorist is contrasted to that available within Piagetian theory. It emphasizes the practical and the occasioned nature of theoretical activity and shows it in everyday settings. Interview conversation between an adolescent and an adult is used as empirical illustration. This formulation of the adolescent as theorist is offered as a means of entry to the scientific constitution of the adolescent as a practitioner of world building who uses the same available resources and does the same sense-making work as any competent member in a culture.Received Ph.D. from University of Toronto. Current interests are the social and scientific constitution of the adolescent, and interpretive methodologies in the study of adolescence.  相似文献

The application of field tests and chromatography to the detection of cocaine and some other local anesthetics that have been used to adulterate cocaine is described. Initial screening of samples by field tests, followed by concurrent TLC and GC, enables rapid identification of these compounds to be achieved. In particular, the use of flow-programmed GC shortens the time for analysis compared with conventional GC and requires negligible equilibration time between consecutive runs [12]. The method gives reliable quantitative data.  相似文献

Samples taken from over 200 seizures of imported illicit heroin preparations of known geographical origin have been examined by gas liquid chromatography (GLC). The chromatographic characteristics were considered in conjunction with the physical appearance of the materials and it was found possible in many instances to discriminate between samples of different origin. Thus by carrying out GLC and HPLC and a visual inspection on a sample of unknown provenance, it may be possible to give an opinion as to its geographical origin.  相似文献

Instantaneous first impressions of facial trustworthiness influence the manner in which observers evaluate ensuing information about stranger targets [e.g. Porter, S., &; ten Brinke, L. (2009). Dangerous decisions: A theoretical framework for understanding how judges assess credibility in the courtroom. Legal and Criminological Psychology, 14, 119–134. doi:10.1348/135532508X281520]. In two studies, we examined the association between perceptions of general trustworthiness and honesty assessments in an extremely high-stakes sample – individuals publicly pleading for the return of a missing relative, half of whom had killed the missing individual. In Study 1, observers (N?=?131) provided trustworthiness ratings – either before or after viewing and evaluating the honesty of videotaped or audio-only pleas – for a still image that depicted a neutral expression on the face of each pleader. In Study 2, observers (N?=?220) evaluated the sincerity of audio pleas paired either with an untrustworthy-looking target, a trustworthy-looking target, or no target face. Collectively, our findings indicated that first impressions of trait trustworthiness form the basis of state judgments of honesty, potentially contributing to misguided credibility assessments and miscarriages of justice in the legal system.  相似文献

Objectives

Drawing on prior theoretical and empirical work on survey participation, this study develops one potential method for increasing response rates and response quality in correctional surveys. Specifically, we hypothesize that providing inmates with a superficial survey choice (SSC)—that is, a choice between completing either of two voluntary surveys that are actually differently ordered versions of the same questionnaire—will increase their motivation both to participate in a given survey and to respond thoughtfully to the questions asked therein.

Methods

We test the effectiveness of this method by evaluating its impact on unit nonresponse, item nonresponse, and answer reliability. To do this, we analyze experimental data from a recent survey of male inmates incarcerated in a medium security, private prison.

Results

Findings indicate that the overall response rate is higher among inmates who are provided a survey choice. In addition, the evidence shows that the SSC method increases the percentage of individual items completed, the number of demanding questions completed, and the reliability of reported responses.

Conclusion

The results from the analyses are consistent with the hypotheses that motivated this study and suggest that the SSC method holds promise as a tool for correctional researchers.  相似文献

Abstract

Globalisation is increasingly placing greater pressure on economies of countries to become competitive and to develop higher levels of skills. In order to compete effectively on a global level, education and development must be based on a good foundation. Although formal education in South Africa is presently reaching the majority of children between the ages of seven and fifteen years, actual educational attainment is low. According to the Third International Mathematics and Science Study, South African pupils performed poorly in Mathematics and Physical Science compared to other participating countries.

This low attainment could be addressed by stimulating a learning culture through the medium of telematics. There have been a number of such nationwide initiatives aimed at transforming the country into a 'knowledge-based society' through the use of ICTs. One such initiative is the University of Pretoria's 'TeleTuks' educational satellite broadcasts to schools.

This article concentrates on the benefits of tele-education for schools participating in TeleTuks as perceived by teachers and by learners. This study was also done to determine to what extent schools are able to participate in the various ICT-related options available; and what problems participating schools are experiencing. It was found that satellite TV is effective in supplementing classroom education by fostering an interactive learning culture, although it has not been utilised and implemented widely enough.  相似文献

This article focuses on the transformatory potential of macroprudential ideas following the financial crash of 2008, examining how they are being mediated by existing institutional contexts and how and why the task of building a new body of technical macroprudential knowledge is proceeding slowly. It is argued that the movement toward a form of macroprudential regulation has a distinctly incremental dynamic that means any macroprudential transformation will be a gradual process that is likely to span a decade or more. Using Peter Hall's framework of three orders of policy change across substantive and temporal dimensions, the article argues that the macroprudential ideational shift can be compared to third order change. In this sense, it was intellectually radical and took place rapidly in a period of around six months. However, intellectual radicalism does not automatically translate into a radical change in regulatory practice, because of a variety of countervailing political, institutional, and informational variables. In this respect, the task of developing first and second order macroprudential policy is proving to be a much more politically contested process. Furthermore, macroprudential policy is being developed by cautious technocrats who rely on the gradual accumulation of data and evidence to justify policy. The result is a distinctly incremental dynamic to macroprudential policy development that displays many of the features of a process that historical institutionalists refer to as “layering.”  相似文献

Since the late 1990's the United States has maintained a strict policy of no cooperation with China on space activities. The reasons for that are several, including the desire to inhibit the development of dual-use technology considered potentially threatening to the United States and political reluctance to work with a communist country. Increasingly, however, it has become clear that policy is not constraining China from dual-use technology development and that the policy overall may be detrimental to U.S. security interests. Therefore a policy change, from a realistic consideration of circumstances, must be considered.  相似文献
