This study used the 1995 National Survey of Family Growth (NSFG) to assess whether characteristics of females' sexual partners, relationships, and choice of contraceptive methods were associated with contraceptive use patterns within their first sexual relationship. White, black, and Hispanic females under age 25 (N=915) provided retrospective information on sexual activity and contraceptive use for first sexual relationships that occurred between 1991 and 1995. Females with older sexual partners and with same race/ethnicity partners (among Hispanics) had reduced odds of ever using contraception and/or uninterrupted use. Longer sexual relationships were associated with higher odds of ever using contraception but lower odds of uninterrupted use. Females who were older at first sex, who used hormonal methods (among whites), or who switched to more effective methods during their first sexual relationships had higher odds of ever using contraception and/or uninterrupted use. In contrast, switching to less effective methods during a first sexual relationship was associated with reduced odds of uninterrupted use.  相似文献

Evaluating federally funded research and development (R&D) presents unique challenges to both federal science agencies and evaluators. Often focusing only on outcome evaluative measures (such as productivity or economic value) can shortchange the true value of the federal investment. For example, program directors at the National Science Foundation (NSF) and National Institutes of Health (NIH) talk about the "value added" of the new interdisciplinary science centers that they have funded-and they hope to be able to capture how funding can generate increased capacity for new cutting-edge research in the future. The purpose of this paper is to present a use-and-transformation model for evaluating public R&D, which explicitly focuses on measuring capacity-based metrics for evaluation instead of outcome-based metrics. The theory for the model presented here explicitly uses the concept of a Knowledge Value Collective that was introduced by Bozeman and Rogers [Bozeman, B., & Rogers, J. D. (2002). A churn model of scientific knowledge value: Internet researchers as a knowledge value collective. Research Policy, 31(5), 769-794; Rogers, J. D., & Bozeman, B. (2001). "Knowledge value alliances": An alternative to the R&D project focus in evaluation. Science Technology & Human Values, 26(1), 23-55].  相似文献

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ 2 and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being. Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically. In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement. Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

Although it would be safe to say that Lesbian Studies has never seriously been placed on the Japanese academic agenda, women-loving-women in Japan continue to individually and collectively desist from and resist heteronormative gender discourses. This paper first gives a brief overview of 'rezubian' communities since the 1970s and then outlines the Basic Law for a Gender Equal Society and the Law Concerning Special Rules Regarding Sex Status of a Person with Gender Identity Disorder; two recent laws that demonstrate contemporary regulatory gender discourses. In closing, I stress that the paradox of contemporary Japanese 'lesbian studies,' being almost nonexistent in the academe and continuously in development in the community, is clear only if we look at academic discourses alongside writings in both commercial and community publications.  相似文献

This short paper examines the extent to which the UK Coalition Government has been inventive or reparatory in their approach to policies governing the education of disabled children and young people. Of central concern here is the extent to which policies contribute to the invention of the disabled child by conceptualising their education as a constant process of reparation. I argue here that this landscape of policy proposals creates particular problems for the ways in which the pedagogic relationship can be conceptualised, reinforcing teaching as a complex negotiation of deficit and anxiety.  相似文献

The purpose of this study was to provide an initial investigation into the work–family conflict (WFC) experiences of individuals who hold a second job. Specifically, we proposed two opposing theoretical arguments regarding the relationship between WFC and four measures of well-being: life satisfaction, physical health, emotional exhaustion, and exercise for individuals who hold two jobs. In a sample of individuals working two jobs, we tested whether the effects of WFC arising from the first job and from the second job exerted an additive or interactive effect on employee well-being. Our results indicated that for emotional exhaustion, physical symptoms, and life satisfaction, the effects of WFC from two jobs are interactive; but that for exercise, the effects of WFC from two jobs are additive. In both cases, the additional WFC experienced as a result of working a second job contributed to the prediction of employee well-being over and above WFC from the first job. Results are discussed within the context of relevant theory, and suggestions are made for future research.  相似文献

The overall purpose of this study was to examine the degree to which retirement is a contextually embedded, family decision rather than an individualized, male-centric one. Using data from a 2010 survey of married pre-retirees ages 35–70 in Michigan, US, we created a General Linear Model to predict expected retirement age. The model incorporated the effect of spousal and family variables on expected retirement age, and because the work/family interface is highly gendered, we explored interactions with gender. The study used a life course perspective in its framing and analysis, and found that expected retirement age was related to both personal and family characteristics and that the relationship of spousal and family factors were gendered and complex.  相似文献

Parents and children exposed to war and relocation have high rates of negative relational and mental health outcomes. This study tested the feasibility of implementing an adapted evidence‐based parenting intervention for contexts of trauma and relocation stress. Eleven Karen refugee caregivers from Burma participated in the intervention. Participants and a focal child completed ethnographic interviews as well as structured assessments at baseline and follow‐up. Caregivers reported changes in their teaching, directions, emotional regulation, discipline, and child compliance. Children reported changes in these areas and in positive parent involvement. Caregivers reported higher mental health distress immediately after the intervention, potentially due to increased awareness. Researchers made personalized referrals for counseling services as needed. Children reported a decrease in mental health symptoms.  相似文献
