This article explored retention patterns, as well as factors that predicted these patterns, in the evaluation of a relationship-based substance abuse prevention intervention study that targeted inner-city African American youth. A total of 851 contacts were made to retain 82% (n = 104) of the baseline sample (N = 127) in the evaluation. Results from multinomial regression analyses indicated that participants who were retained in the evaluation were more likely to perceive alcohol, tobacco, and other drug use as less risky and were more likely to report higher levels of family supervision than were evaluation attrits. Those who were easy to retain reported lower family conflict and fewer family relocations during the past year than those who were difficult to retain. Implications of these findings for developing retention strategies, as well as future research, are discussed.  相似文献

The audit fees available since 2005 as a consequence of the Bilanzrechtsreformgesetz (commercial code reform act) show an extremely high supplier concentration on the German audit market of publicly listed companies. This justifies the assumption of audit fees above perfect market equilibrium prices. However, the complete collection and multivariate regression analysis of all relevant audit fee and client data document a 24 % decrease in audit fees in 2005 and an average 15 % decrease in the two subsequent years due to auditor changes. This can be interpreted as an indicator for price competition. In addition, the audit fee data shows that the audit fee decreases are only partially compensated by subsequent increases. As a consequence, there is no evidence for lowballing at present. Further time series are necessary to show if the current trend is sustainable.  相似文献

Understanding the reliability of hazardous organizations and their protective systems is central to understanding the risk they produce. Work on “high reliability organization” has done much to illuminate the conditions in which social organization becomes reliable in highly demanding conditions. But risk depends just as much on how relying entities do their relying as it does on the reliability of the entities they rely on. Patterns of relying are often opaque in sociotechnical systems, and processes of relying and being relied on are mutually influencing in complex ways, so the relationship between relying and risk may not be at all obvious. This study was an attempt to study relying as a social practice, in particular analyzing how it had ecological validity in a social organization—how practice was responsive to the conditions in which it took place. This involved observational fieldwork and inductive, qualitative analysis on an offshore oil and gas production platform that was nearing the end of its design life and undergoing refurbishment. The analysis produced four main categories of ecological validity: responsiveness to formal organization, responsiveness to situational contingency, responsiveness to information asymmetry, and responsiveness to sociomateriality. This ecological validity of relying practice should be a primary focus of risk identification, assessing how relying can become mismatched to reliability in certain ways, both when relying practice is responsive to circumstances and when it is not.  相似文献

Abstract

Objective: To investigate the relationships between adverse childhood experiences (ACEs), post-traumatic stress disorder symptoms (PTSD-S), and self-reported stress among college students. Participants: A total of 236 undergraduate students enrolled in nursing courses participated. Method: Using a correlational design, participants completed questionnaires online. To examine PTSD moderation between ACE and self-reported stress, multiple regression was employed. Stress outcomes were examined using a 4-group variable. Mean differences in stress response between these four groups were examined. Differences in ACE, PTSD-S, and stress response between traditional and nontraditional students were also examined. Results: PTSD-S moderated the relationship between ACEs, and self-reported stress. This indicates that students who report PTSD-S following childhood adversity perceive higher levels of stress. Nontraditional and traditional students differed in their responses to the ICLRE scale. Conclusion: Individuals who report PTSD-S following childhood adversity perceive higher levels of stress later in life. Stress reduction programs may be beneficial for students.  相似文献

Although the predictors of off-line relational aggression have been examined in prior work, less is known about the factors that contribute to online relational aggression perpetration and victimization. This study examined parental restrictive and active mediation of teenagers’ social media use as potential predictors of these outcomes. We were particularly interested in understanding whether parental agreement about media rules and the consistency with which mediation was implemented had implications for teens’ social media use, conflict with parents, and experience with online relational aggression. We conducted an online survey of 814 adolescents from the United States (14- to17-year-olds), asking about perceived agreement between parents about media rules, parental mediation styles, the teens’ social media use, and their experiences with online relational aggression. Results showed that parental rule agreement negatively predicted inconsistent parental mediation. Inconsistent parental mediation predicted more adolescent social media use and more parent-teen conflict over media rules, which in turn, predicted both online victimization and perpetration.  相似文献

Existing research indicates that clients perceive facially attractive therapists as more competent, trustworthy, genuine, and effective than less attractive therapists. No Studies exist to help explain how the therapist's attractiveness influences a client's self-disclosure. Participants (n = 241) were randomly assigned to one of eight experimental groups to test the interaction of the therapist's attractiveness, client's gender, the nature of presenting problem, and the client's comfort with disclosing in a hypothetical couple therapy scenario. Analysis of variance procedures established that most participants reported feeling more comfortable disclosing a benign (communications) problem than a potentially embarrassing (sexual) problem, and more comfortable disclosing problem to an attractive than to a less attractive female therapist. Therapists are encouraged to understand the power attractiveness may have in their own and their client's lives  相似文献

A study into the relationships between candidateself-monitoring ability, interviewer perceptions ofcandidate personality, and interviewer outcome decisionsin the context of actual graduate recruitment interviews (n = 130) is presented. Detailedpsychometric norm data is also reported on the Lennoxand Wolfe (1984) revised Self-Monitoring (RS-M) scale,together with the results of confirmatory factoranalyses into the factor structure of this measure. Itwas found that candidate self-monitoring ability wasonly moderately and nonsignificantly related tointerviewer outcome evaluations, and thatself-monitoring was generally uncorrelated with thepositiveness of recruiter impressions of candidatepersonality. Confirmatory factor analyses revealed thata two correlated factor structure for the RS-M scale, inaccordance with the original authors' formulation,provided the most parsimonious fit. Norm data for theRS-M scale is reported for this sample of Britishgraduates, including item statistics, item to subscale,item to scale correlations, and internal reliabilitycoefficients. Implications for future research intocandidate impression management, self-monitoring,interviewer decision making, and the practicalimplications arising from these findings arediscussed.  相似文献

The central issue of this paper is that one can develop emergent macro-dynamics from micro agent models and that the resulting models fall very much in the complexity-chaos line of the development of theory. The core theoretical contribution is a presentation of a clear, sensical, and potentially very powerful architecture for developing algorithms for the embedding of levels—the so-called master equation approach—and its comparison with alternative architectures. Finally, to illustrate the strategy and to demonstrate that the approach produces interesting and useful results, we give an application: a multilevel simulation model of military coups d'état, which is tested using data from Thailand between 1932 and 1992.  相似文献
