Alcohol consumption and related problems are common among underage college students, yet qualitative, in-depth information on how/where these students obtain alcohol is limited. We conducted focus groups pertaining to access to alcohol and related issues with 19 underage college students. They reported that alcohol is easy to obtain from a variety of sources, with friends/acquaintances who are of legal age or those with a false ID being the most common. Parties were also common sources, but "shoulder tapping" (i.e., asking a stranger to purchase alcohol) was not common. Disagreement arose over whether underage fraternity/sorority members have greater access to alcohol than non-Greeks. Our results provide updated information on the various sources of alcohol and associated issues among underage college students. 相似文献

Two parallel surveys were carried out based in the north-east of England and Cumbria: one ascertaining statutory social work services provided for child and adult survivors of sexual abuse, the other drawing upon the perceptions of adult survivors of child sexual abuse about existing and desirable forms of provision for adults and children. The surveys indicate the need for greater genuine partnership between service users and statutory agencies in the field of child sexual abuse, similar to that which is being pioneered in the field of adult care and disability. A community-orientated response to sexual abuse, centred on service-users, is required if one of the largest social problems facing us today is to be effectively challenged. 相似文献

Correspondence to Dr Adital Ben-Ari School of Social Work, Faculty of Social Welfare and Health Studies, University of Haifa, Haifa, Israel 31905. Summary The present study explores the relationship between perceivedsocial support and well-being among students of the three mainpopulations living in Israel: Israeli-born Jews, Israeli-bornArabs and Russian immigrants. More specifically, it comparesthe well-being of these three groups and examines to what extentperceived social support actually contributes to their well-being.The sample comprised 278 undergradute students in the schoolsof social work and nursing at one of the major universitiesin Israel. Three instruments were used. Well-being was measuredby both the Brief Symptoms Inventory Scale (Derogatis, 1979)and the Beck Depression Inventory (Beck and Steer, 1987). Perceivedsocial support was assessed by the Multidimensional Scale ofPerceived Social Support (Zimet et al., 1988). The findingsshow that the Arab students are significantly more distressedthan their Jewish and Russian counterparts on all measures ofwell-being. At the same time, their perceived social supportis significantly higher than that of the Jewish students (bothIsraeli-born Jews and Russian immigrants). Stepwise linear regressionanalysis revealed that while perceived social support was amajor contributor to the explanation of well-being among theIsraeli students, it did not surface as a significant explanatorypredictor of well-being among either Arabs or Russian immigrants.The significance of the findings is discussed within the theoreticalframeworks of stress and social support theories as well asmodernization and immigration processes. 相似文献

ABSTRACT There is little research about trauma, financial stress, and social service needs emanating from the experience of parenting grandchildren caused by the opioid crisis in the United States. We conducted a qualitative study with 15 grandparents who currently or in the past had custodial care of their grandchildren. We also interviewed nine issue-related stakeholders in Eastern Massachusetts. Specific inquiries centered on events leading up to a change in guardianship, stressors related to legal, financial, and family issues, and system-wide response to the grandparents’ needs. Results indicate that the opioid crisis presents distinct challenges for the grandparent-led families and for the systems that serve the new family arrangement. Crisis triggers a change in guardianship and continues throughout the years. The continued crises stem from events related to the parent’s opioid use disorder (OUD) and from expenses related to raising a young family, especially when the grandchild has adverse childhood experiences. Our analysis shows that systems break down on a number of levels, and the fluidity of custodial arrangements due to parents’ OUD status does not map onto existing support or benefit systems. Policy responses must focus on the immediate and long-term needs of grandparent caretakers, especially since the opioid crisis is likely to continue. 相似文献

This article proposes and evaluates two new methods of reweighting preliminary data to obtain estimates more closely approximating those derived from the final data set. In our motivating example, the preliminary data are an early sample of tax returns, and the final data set is the sample after all tax returns have been processed. The new methods estimate a predicted propensity for late filing for each return in the advance sample and then poststratify based on these propensity scores. Using advance and complete sample data for 1982, we demonstrate that the new methods produce advance estimates generally much closer to the final estimates than those derived from the current advance estimation techniques. The results demonstrate the value of propensity modeling, a general-purpose methodology that can be applied to a wide range of problems, including adjustment for unit nonresponse and frame undercoverage as well as statistical matching. 相似文献

Using data from both partners in female same-sex couples, individual and dyadic (individual/actor-partner) level analyses were conducted to determine the associations between couple members' global mental health, internalized homophobia, and perceptions of relationship qualities and satisfaction (N = 90). Findings at the dyadic level indicated that an individual's global mental health was uniquely associated with her partner's assessment of relationship satisfaction and qualities, beyond the effects of the individual's own mental health and internalized homophobia. Implications for further research on the strengths and challenges within female same-sex couple relationships are discussed. 相似文献

Is the measurement of ‘safety culture’ a valid management tool in the effort to reduce accident rate and improve safety performance, or is it a fuzzy academic concept, lacking empirical validation? The answer to this question seems to depend on whom one asks. The UK Health and Safety Commission has encouraged companies to improve their safety performance through the development of a ‘positive safety culture’. However, academic discussions in this area suggest that the concept remains vague, lacks empirical validation and is used as an ‘umbrella term’ for all the social and organizational factors that affect accident rate. This paper reviews the existing literature on safety culture and provides some clarification in terms of definition, empirical evidence and theoretical development. A theoretical framework of the mechanisms by which safety culture affects safety behaviours in organizations is proposed. The implications for practical management issues are discussed and future challenges and areas for further research are identified. 相似文献

A sequential time-variation method is utilized in an attempt to detect changes over time in the effectiveness of market communication for an ethical drug. Sudden changes are indicated at three different points in time, and two of these are confirmed by subsequent analysis and information. Gradual changes are also indicated, but these are not confirmed by market information or statistical analysis. 相似文献

ABSTRACT: Chronic unemployment and slow employment growth in some countries have led to calls for more labor-market “flexibility”. This paper defines the flexibility issue in terms of legally-mandated “severance”, a generalized employment cost linked to seniority. A mandated severance benefit can stand for a variety of programs including employer-provided employment guarantees, payments which must be made to laid-off workers, and compensation for wrongful discharge. Such a mandated cost can be seen as a payroll tax on the employer, raising the issue of tax incidence. Employers often take the view that labor costs are given and that mandated costs are simply add-ons to pre-existing cost levels. However, the literature on tax incidence suggests that a significant portion of “employer-paid” payroll taxes are shifted to labor in the form of lower wages. Such shifting should reduce the dis-employment effects attributed to severance. A model is provided of a firm upon which a severance mandate is imposed. Even at the micro level, the firm can shift some of the cost of severance to employees by lowering wages — although at the expense of higher turnover costs associated with increased quit rates. At the macro level, to the extent that firms reduce employment, there could be still further downward wage adjustments which would shift the severance burden to labor and mitigate the dis-employment effect. Ultimately, if the natural rate of unemployment is raised by severance mandates, the age-old question is raised of why wages do not fall in the face of labor surpluses. The true inflexibility to be explained, therefore, is in wage determination. 相似文献
