Until relatively recently racial and ethnic minorities were concentrated in particular economic niches. This paper explores the hypothesis that one mechanism that facilitated the maintenance of such niches was for employers to accept referrals from existing employees of particular ethnic backgrounds. This hypothesis is pursued through an analysis of job histories obtained from forty-five elderly black, Italian, and Jewish migrants to New York. The results indicate racial differences in the way that respondents obtained jobs. Moreover, the relationship between means of entry and the minority of composition of firms varied across all three groups. 相似文献

The purpose of this article is to examine factors related to the professional involvement of highly educated women. Three indicators of involvement are considered: nonemployment, part-time work, employment not making use of highest degree. The sample consists of 663 women who received high-level degrees from a large midwestern university between 1964 and 1974. Results indicate that both family role position and role bargaining outcomes play a major role in determining the level of involvement. Indicators of the latter, including previously untested measures of the timing of family and career beginnings and husband's moves for his wife's career, were important determinants of all three measures of involvement. As a caveat, we question the culturally pervasive assumption that lower involvement is necessarily negative. Information from a small number of in-depth interviews suggests that these women value an overall balance between work and family rather than consistently high levels of professional involvement. Future research must explore this possibility. 相似文献

Evidence is emerging that youth who attend out-of-school-time (OST) programs more frequently and for longer periods of time benefit more than youth who attend less frequently or do not attend at all. It is also increasingly clear that children and youth will not reap the benefits of programs if they do not attend regularly. Collecting attendance data can help program leaders gauge demand for services, plan and manage programs effectively, and evaluate participant outcomes in relation to attendance. This chapter presents these and other reasons for collecting attendance data, as well as the methods and techniques that program leaders and researchers have at their disposal for measuring attendance. It describes four indicators of attendance--absolute attendance, intensity, duration, and breadth--that can provide detailed information and insight about youth participants and their use of programs. The chapter also provides tips for collecting attendance data and features examples from OST programs. Throughout, the chapter illustrates that the right indicators and data collection methods depend on program needs, characteristics, and goals. 相似文献

Clinical social workers highly value client self-determination yet little is known about how the practitioner applies the concept in ongoing practice. In a small exploratory study, 20 social workers, randomly selected from Utah's licensure list, were interviewed in depth about decision-making related to client self-determination. Even in a small, relatively homogeneous population, enormous variations were found in the application of the principle. 相似文献

This paper discusses measurement issues related to the evaluation of computer-tailored health behavior change programs. As the first generation of commercially available tailored products is utilized in health promotion programming, programmers and researchers are becoming aware of the unique challenges that the evaluation of these programs presents. A project is presented that used an online tailored health behavior assessment (HBA) in a worksite setting. Process and outcome evaluation methods are described and include the challenges faced, and strategies proposed and implemented, for meeting them. Implications for future research in tailored program development, implementation, and evaluation are also discussed. 相似文献

Research indicates belonging to a gay, lesbian, and bisexual (GLB) support group is indirectly associated with fewer depressive symptoms, via higher levels of sense of belonging to the general community. The current study extended this research by testing a path model to determine whether school, teacher, and peer connectedness are influenced by sense of belonging to a community GLB youth group. A sample of 82 Australian GLB adolescents aged 14 to 18 years who currently attend high school completed the Center for Epidemiologic Studies Depression Scale, the Psychological Subscale of the Sense of Belonging Instrument, and the Social Questionnaire for Secondary Students. Results indicated very good model fit. Higher levels of belonging to a community GLB youth group were associated with higher levels of school, teacher, and peer connectedness, but only peer connectedness was directly associated with depressive symptoms. Higher levels of school and teacher connectedness were associated with higher levels of peer connectedness. Interventions aimed at increasing belonging to a community GLB youth group may have indirect benefits for the mental health of GLB adolescents, via higher levels of school, teacher, and peer connectedness. 相似文献

The North American Free Trade Agreement (NAFTA) and the General Agreement on Tariffs and Trade (GATT) have focused attention on risk assessment of potential insect, weed, and animal pests and diseases of livestock. These risks have traditionally been addressed through quarantine protocols ranging from limits on the geographical areas from which a product may originate, postharvest disinfestation procedures like fumigation, and inspections at points of export and import, to outright bans. To ensure that plant and animal protection measures are not used as nontariff trade barriers, GATT and NAFTA require pest risk analysis (PRA) to support quarantine decisions. The increased emphasis on PRA has spurred multiple efforts at the national and international level to design frameworks for the conduct of these analyses. As approaches to pest risk analysis proliferate, and the importance of the analyses grows, concerns have arisen about the scientific and technical conduct of pest risk analysis. In January of 1997, the Harvard Center for Risk Analysis (HCRA) held an invitation-only workshop in Washington, D.C. to bring experts in risk analysis and pest characterization together to develop general principles for pest risk analysis. Workshop participants examined current frameworks for PRA, discussed strengths and weaknesses of the approaches, and formulated principles, based on years of experience with risk analysis in other setting and knowledge of the issues specific to analysis of pests. The principles developed highlight the both the similarities of pest risk analysis to other forms of risk analysis, and its unique attributes. 相似文献
