Heavy episodic drinking and college entrance   总被引:1,自引:0,他引:1  
The college environment appears to encourage heavy drinking. Consequently, correlates of student drinking were assessed at college entrance. First-semester freshmen (N = 520, 54 percent women) completed self-report measures of social affiliation and self/peer drinking for high school and college. Analyses indicated that: 1) increased drinking at college entrance mirrored perceived increases by peers, 2) perceptions of peer drinking were robustly overestimated with women displaying the larger overestimation bias; and 3) social affiliation was associated with men's drinking and moderated its relation to perceived peer drinking at college entrance. These results advance understanding of the manner in which heavy drinking patterns emerge as men and women enter college, and campus programs that consider these factors may better promote health and reduce the harms associated with heavy drinking among college students.  相似文献

The objective of this article is to assess the effect of abuse cessation on depressive symptoms among women abused by a male intimate partner. This prospective cohort study of Seattle women with a history of intimate partner violence (IPV) who were classified by history of abuse and abuse status at 3 month, 9 month, and 2 year follow-up interviews. Relative risks (RR) were calculated using generalized estimating equations. Among subjects with a history of psychological abuse only, cessation of abuse was associated with a nonsignificant reduction in the likelihood of depression compared to subjects whose abuse continued (aRR = 0.88; 95%CI: 0.75,1.03). Among subjects with a history of physical/sexual abuse and psychological abuse, cessation of physical/sexual abuse only was associated with a 27% decline, and cessation of both types of abuse was associated with a 35% decline in the likelihood of depression (aRR = 0.73, 95%CI: 0.63,0.86; and aRR = 0.65; 95%CI: 0.55,0.76; respectively). Cessation of abuse among victims of IPV is associated with a decreased prevalence of depression.  相似文献

In this article, the Four S Model is presented as a working clinical framework for generating structured nursing interventions and treatment plans. The de-escalation process, formalized by the De-escalation/Alternative to Restraint Flowsheet, is one way in which the model is being operationalized to reduce seclusion and restraints. As shown by the flowsheet, the model allows for integration of mental health and mental illness. It spans the scope of nursing practice at all levels, from para-professional to advanced practice nurse, by integrating the mental health concepts of communication, leadership, clinical judgement, critical thinking, and caring within its framework. Most important, the flexibility to individualize treatment that is built into the model allows for generalization to all psychiatric presentations.  相似文献

Abstract: There are plenty of stereotypical discourses concerning the Korean minority in Japan that are widely accepted, not because of their plausibility, but because of the lack of basic empirical data. In order to fill this intellectual vacuum, I conducted a social stratification and mobility survey focusing on resident Korean men in 1995, comparable with the Japanese sample. The purpose of this article is exploratory rather than aimed at hypothesis testing, given the extreme paucity of the earlier empirical data for the ana‐lysis of Korean minority status attainment. The results show that:  
  • 1 For the Korean minority in Japan, class resources translate into educational attainment to a much lower extent than for the Japanese.
  • 2 Korean status attainment patterns deviate from those of their Japanese counterparts. For the Japanese, the crucial status attainment path is secured through educational attainment, which is not the case among Koreans.
  • 3 Despite being denied access to such mainstream status attainment paths, major status indicators for Koreans are not significantly different than those of Japanese, and regarding this equality of outcomes, one of the possible explanations is that Korean ethnic disadvantages in the status attainment process may have been overcome by mobilizing informal bilateral ethnic networks.

We identify managerial challenges offered by an emergent nanotechnology innovation system in which knowledge is dispersed, asymmetric and contested. We argue the proposed models of knowledge absorption and transformation enhance existing theories of knowledge and emergent technology by recognizing how and why knowledge flows among the actors in emergent technology innovation system. We base our argument on combined research evidence from a Delphi study concerning the future of European manufacturing, from which a selected statement has been analyzed, and from analysis of the NanoManufacturing Institute at Leeds University, UK; specifically its work in building ties between different actors associated with nanotechnology. We conclude our paper with suggestions for future research.  相似文献

A study of industrial engineering in seven European countries was carried out for the purpose of comparing European organization and practice in that field with the American situation as revealed by an earlier survey. The data obtained relate to organizational variables such as distinctiveness, location, degree of centralization and contact with headquarters; staffing factors such as number of personnel and their education, and the use made of specified techniques. Changes and trends in these terms are then explained. The data suggest that Europe and the U.S. are essentially similar. Finally, the future of industrial engineering is explained in terms of the demands which will be made on industry and the contribution which industrial engineering can make to meeting these.  相似文献

One hundred ninety-two children in foster care participated in a randomized efficacy trial of a school readiness intervention, the Kids In Transition to School (KITS) Program, designed to increase literacy, social, and self-regulation skills in children before kindergarten entry. One hundred two children were randomly assigned to the KITS intervention and 90 were randomly assigned to the foster care services as usual comparison group. At the end of the kindergarten year, teachers were asked to report on the children's oppositional and aggressive behaviors in the classroom. Controlling for gender, baseline levels of parent-reported oppositional and aggressive behaviors, and level of disruptiveness in the classroom, children who had received the intervention had significantly lower levels of oppositional and aggressive behaviors in the classroom. Findings suggest that an intervention designed to increase school readiness in children in foster care can have positive effects on kindergarten classroom behavior.  相似文献

Despite growing concerns about foster placement instability, little information is available regarding the longitudinal patterns of placement histories among foster children. The purpose of the present study was to develop a charting system using child welfare records to facilitate a better understanding of longitudinal patterns of placement history for 117 foster children. The resulting Placement History Chart included all placements that occurred during the observed time period and accounted for various dimensions: number, length, type, and sequence of placements; timing of transitions; and total time in out-of-home care. The Placement History Chart is an effective tool for placing foster care experiences within a broader developmental context. As such, the Placement History Chart can be a valuable research tool for understanding various dimensions and variations of placement transitions among foster children by capturing sequences and cumulative risks over time. Furthermore, this chart can facilitate the development of intervention programs that are developmentally sensitive and effectively address particularly vulnerable subpopulations of foster children.  相似文献

Pay-What-You-Want (PWYW) is a participative pricing mechanism which is characterized by the fact that consumers have maximum control over the price they pay. We discuss the business relevance of PWYW and extend the findings of Kim et al. (2009) using latent class regression. Two different classes can be identified and transaction prices are explained by psycho- and socio-demographics. The estimation of the parameters shows that the internal reference price is a good predictor for the prices in class 1, whereas in the 2nd class the level of fairness and satisfaction with the product positively affect the final transaction prices.  相似文献

This article assesses Charles Tilly’s Durable Inequality and traces its influence. In writing Durable Inequality, Tilly sought to shift the research agenda of stratification scholars. But the book’s initial impact was disappointing. In recent years, however, its influence has grown, suggesting a more enduring legacy.  相似文献
