Those who are more emotionally invested in relationships have less power than their partners. Furthermore, less powerful individuals may attempt to equalize power imbalances by offering rewards to their partner and using sex and condom use as exchange resources. Australian young adults reported their condom use and pressured sex experiences in both romantic (n = 708) and casual (n = 118) relationships. Results showed that greater power (lower relative emotional investment) predicted more condom use among those wanting to use condoms. In casual relationships, an interaction with gender showed that women in particular used condoms more when they had more power. Power also interacted with gender for pressured sex and, unexpectedly, men who had more power experienced more pressured sex. The possibility that condom use and pressured sex have different meanings for men and women is explored. 相似文献

This study uses a factorial vignette design embedded in an Internet survey to investigate attitudes toward an adult child and parent living together in response to economic hardship. Over half of Americans said the desirability of intergenerational co-residence depends on particularistic aspects of the family, notably the quality of family relationships. Support for co-residence is greatest when the adult child is single rather than partnered. Support is weaker if the adult child is cohabiting rather than married to the partner, although groups with greater exposure to cohabitation make less of a distinction between cohabitation and marriage. Presence of a grandchild does not affect views about co-residence. There is more support for sharing a home when a mother needs a place to live than when the adult child does. Responses to open-ended questions show that individuals invoke both universalistic family obligations and particularistic qualities of family relationships to explain their attitudes. 相似文献

Homeless youth lack the traditional support networks of their housed peers, which increases their risk for poor health outcomes. Using a multilevel dyadic analytic approach, this study identified characteristics of social contacts, relationships, and social networks associated with the provision of tangible and emotional support to homeless youth (N = 419, M age = 20.09, SD = 2.80). Support providers were likely to be family members, sex partners, or non–street‐based contacts. The provision of support was also associated with contacts' employment and homelessness status, frequency of contact, shared risk behaviors, and the number of network members that were homeless and employed. The results provide insights into how homeless youth could be assisted to develop more supportive social networks. 相似文献

Conventional advice is to reduce risky investments as one ages. Such a generalized focus on risk avoidance may be inappropriate for elderly with longer life spans and those with financial goals that extend beyond their lifetime. To better understand risky asset holdings among the elderly, we investigated the effect of cognitive ability and bequest motive on stock ownership and stock purchase. Using the 2004 wave of the Health and Retirement Study, we found that one-third of elderly households held stocks and 36% of those elderly stockowners had recently acquired stocks. The respondent??s cognitive ability and bequest motive were strongly related to stock ownership. Among those who owned stock, a bequest motive was positively related to a recent purchase of stocks. 相似文献

Research regarding lesbian mothers and their children has gone through a transformation in the last forty years. The first wave of research examined lesbians who had become parents while in heterosexual relationships. The second wave examined women who became parents within the context of lesbian relationships. Both of these waves focused on family functioning and child outcome, using heterosexual-headed families as comparison groups. The third wave of research, which is now underway, is focusing on the unique challenges faced by these families, and how lesbian mothers are creating and raising their families on their own terms. This article explores the research as it has evolved over the years and the direction in which it is headed. 相似文献

The aim of this paper is to examine what we know about the experience and outcomes of networked initiatives aimed at facilitating practitioner research. We outline the roles and significance of practitioner research within social work; review emerging understanding of practitioner research network initiatives; and draw conclusions from a comparative analysis of three such initiatives in Auckland, New Zealand, Arhus County, Denmark, and across Scotland. We consider the nature and challenges of practitioner research and a number of responses to how such work should be formulated and conducted. Central to our argument is an empirically informed consideration—from our separate and shared experiences—of how well networks enhance the process and consequences, and art and craft, of such research projects. 相似文献

Green roofs are emerging engineered ecosystems that provide multiple benefits, but many are constructed with nutrient-rich substrate and have been found to leach out high levels of phosphorus (P) in runoff. It is unclear, however, how long green roofs act as sources of P or what mechanisms are responsible for these net losses. We measured P concentrations in runoff water over 4 years from a 1–5 year old extensive green roof in Cincinnati, OH, USA, produced a model to predict runoff P levels into the future, and validated predictions using runoff from 2 nearby extensive green roofs. P concentrations in runoff from the focal green roof were on par with heavily fertilized agroecosystems and displayed strong seasonal dynamics and a rapid decline over the 4-year study. Runoff measurements and changes in substrate P content over a 2-year period were used to estimate a mass balance for green roof P. P loss from the substrate was substantial (4.55 ± 2.3 g P/m2/yr), but only a small portion of the loss was attributable to leaching of P in runoff (0.19–0.65 g P/m2/yr). Missing P may be attributed to a combination of plant uptake and altered P form and binding strength, but further research is needed to precisely identify the mechanisms of P depletion. Our results also suggest that these and similar extensive green roofs are likely to act as environmentally significant sources of P for 10 or more years following roof installation, highlighting the need for reductions in initial substrate P content. 相似文献

Swiss gambling legislation is unique in the fact that it includes health concerns and obligations for gambling operators. Specifically, they are required to provide social measures for the prevention of problem gambling and to collaborate with prevention centres. These provisions are crucial for the development of problem gambling prevention and training programmes. Further, they open important research avenues to make use of data collected within the industry. The present article provides an insight into these specific aspects of Swiss gambling legislation. It also illustrates recent examples of research that has been conducted on the basis of these legal provisions and considers their results. 相似文献
