This study examined the relations between peer assessment and long-term law enforcement/job performance. Sixty-nine law enforcement cadets completed peer rankings of likelihood of success in job performance. These peer rankings were significantly correlated with supervisor ratings, as well as absenteeism and retention, after 1 year of employment. In the present study, both subjective and objective job performance data were collected from a variety of employing job performance agencies after 6 years of employment. Peer rankings were still significantly correlated (r=.40, p<.05) with retention after 6 years, but were not significantly correlated to any job performance index. These results support the potential usefulness of peer assessment data even after several years have passed. © 1998 John Wiley & Sons, Ltd.  相似文献

Correct running form is important for injury prevention; as such, correct form promotes continued engagement in running as a long-term form of exercise. Researchers have shown video feedback to be an effective strategy to improve athletic form for a variety of sports, but it has not been evaluated in any behavior analytic research as a method for improving running form. The purpose of this study is to evaluate the effectiveness of video feedback to improve running form for regular runners. During baseline, each participant was video recorded while running without any feedback (verbal or video). During intervention, the researcher recorded the participant, then showed them the video and provided feedback on correct or incorrect form, according to a 9-step task analysis. Results show that all three participants achieved 100% correct steps on the task analysis when video feedback was used to maintain their form during follow-up.  相似文献

Healthcare providers assume that there are minimal risks and potential psychosocial benefits for children who undergo a bone marrow harvest for the benefit of their critically ill siblings. Ethical justifications for the use of children as donors rely on there being minimal risks since donors receive no direct medical benefits from the intervention. There is little empirical research regarding psychosocial consequences. This article reviews relevant research in three contexts: a) psychosocial outcomes for adults and children who donate tissue and organs; b) psychosocial impacts on a sibling of a pediatric cancer patient; and c) children's decision-making regarding medical decisions. The relevant research literature supports the belief that the psychosocial impact on a child bone marrow donor will be influenced by the survival of the recipient, the age of the donor, and the donor's participation in the decision to donate. In order to empirically validate the actual psychosocial risks (and benefits) for donors, it is argued that direct research is needed so that a donor's well-being can be protected.  相似文献

In this paper, we utilize GIS (Geographic Information System) mapping data to locate eleven immigrant congregations and the residential addresses of their members in Houston, Texas. Combining this information with ethnographic data allows us to understand how ecological variables impact organizationalcharacteristics of religious institutions. Specifically, we combine GIS and ethnographic data on immigrant congregations in Houston, Texas, to analyze characteristics that make them more parish or niche-like in structure. We demonstrate that the combination of GIS techniques and standard field methods yields the greatest potential to provide a comprehensive understanding of what congregations mean to their members.  相似文献

We investigated the interrelations between dimensions of perfectionism and measures of academic motivation and learning strategies in university students. When partial correlation analysis was employed to examine the unique relation between specific perfectionism subscales and motivation/learning scales, self-oriented perfectionism was significantly related to students’ motivation and learning strategies in positive, adaptive ways whereas socially prescribed perfectionism was related in negative, maladaptive ways. Self-oriented perfectionists were motivated primarily by extrinsic compensation for their academic work whereas socially prescribed perfectionists were more motivated by recognition from others. Self-oriented perfectionism was significantly positively associated with self-efficacy for learning and performance, adaptive metacognitive and cognitive learning strategies, and effective resource management. Socially prescribed perfectionism was associated negatively with these measures. In addition, self-oriented perfectionism was associated positively with intrinsic goal orientation for a specific course, task value, and critical thinking whereas socially prescribed perfectionism was associated with test anxiety and a decreased likelihood of help-seeking. The theoretical importance of these findings and the implications for devising strategic counseling interventions are discussed.  相似文献

The turn of the century is an apposite time to review the development of guidance in the United Kingdom. The concept of guidance, in the terms in which it is now understood, is very much a 20th-century notion. It draws on two distinct but related traditions: the development of the practice of career guidance; and the development of guidance as an educational concept. The history of these two developments, and the relationship between them, are briefly outlined. Some of the conceptual issues they raise are examined, including the important but somewhat problematic interface with counselling. Challenges for guidance in the new millennium are discussed, in relation both to policy and practice and to theory and research.  相似文献

Forty undergraduate Rutgers-Newark students (21 women and 19 men) of Portuguese descent, aged 18 to 28, participated in a study on identity com-mitment and attitudes toward interethnic dating. High commitment to a Portuguese identity was associated with a collectivist orientation and with having a social network densely populated with Portuguese people. High personal concern with the ethnicity of one's dating partner was positively correlated with commitment to a Portuguese identity, and with having a social network densely populated with Portuguese people. High importance placed on parents' opinions about the ethnicity of dating and marriage partners was associated with a collectivist orientation. For women but not men, commitment was associated with high concern with one's partner's ethnicity. Results are discussed in terms of gender and the development of commitment to an ethnic identity.  相似文献

In survey research, the use of decomposition can lead to pronounced reporting errors as seen by overreporting and overall reporting error. A total of 87 subjects answered either decomposed or undecomposed questions concerning telephone calls made by them while at work. The questionnaire conditions varied the length of the reference period (1 week or 6 months), and the type of call (local or long‐distance). Decomposition conditions introduced either spatial or temporal cues. In all comparisons, decomposed questions increased overreporting bias relative to undecomposed questions. In addition, undecomposed questions with a 1‐week reference period led to increased overreporting bias in comparison to undecomposed/6‐month questions. Results are consistent with a category split estimation model in which smaller categories are predicted to lead to overreporting, and larger categories to underreporting. Decomposition is not recommended for gaining retrospective reports of non‐distinctive, frequent events. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

The HIV-1 transgenic (Tg) rat model is valuable for understanding HIV-associated neurocognitive disorders (HAND) and accompanying substance use and misuse. Tg and F344/NHsd wildtype (WT) rats were allowed to self-administer intrajugular cocaine. For the first 7 sessions, neither genotype self-administered cocaine (0.1 mg/kg/infusion) on a fixed ratio 1 schedule. We thus implemented a lever–cocaine “autoshaping” session followed by a series of manipulations changing dose and reinforcement schedule. Tg rats self-administered much less cocaine than WT rats throughout the study. Of 8 Tg rats, 5 modestly increased self-administration from sessions 36–50. Of those, only 3 showed a lever discrimination. Of 10 WT rats, 8 acquired robust self-administration by session 19; all WT rats self-administered cocaine by the end of the study. WT and Tg rats had similar baseline locomotor activity in the self-administration chamber suggesting that the low levels of cocaine intake in the Tg rats did not reflect a nonspecific motor impairment in this rat strain. Concomitant measurement of activity with self-administration revealed activity increases that followed increased cocaine intake. That relation held in Tg rats. Therefore, the present study provides evidence that HIV-1 Tg rats are less sensitive to the reinforcing effects of cocaine than their F344 WT counterparts.  相似文献
