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

Several models for studies related to tensile strength of materials are proposed in the literature where the size or length
component has been taken to be an important factor for studying the specimens’ failure behaviour. An important model, developed
on the basis of cumulative damage approach, is the three-parameter extension of the Birnbaum–Saunders fatigue model that incorporates
size of the specimen as an additional variable. This model is a strong competitor of the commonly used Weibull model and stands
better than the traditional models, which do not incorporate the size effect. The paper considers two such cumulative damage
models, checks their compatibility with a real dataset, compares them with some of the recent toolkits, and finally recommends
a model, which appears an appropriate one. Throughout the study is Bayesian based on Markov chain Monte Carlo simulation. 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

Background
Pregnancy, labour and neonatal health outcomes for Australian Aboriginal women and their infants are frequently worse than those of the general population. Provision of culturally competent services may reduce these differences by improving access to timely and regular antenatal care. In an effort to address these issues, the Aboriginal Maternity Group Practice Program commenced in south metropolitan Perth, Western Australia, in 2011. The program employed Aboriginal Grandmothers, Aboriginal Health Officers and midwives working in a partnership model with pre-existing maternity services in the area.Aim
To identify elements of the Aboriginal Maternity Group Practice Program that contributed to the provision of a culturally competent service.Methods
The Organisational Cultural Competence Assessment Tool was used to analyse qualitative data obtained from surveys of 16 program clients and 22 individuals from partner organisations, and interviews with 15 staff.Findings
The study found that the partnership model positively impacted on the level of culturally appropriate care provided by other health service staff, particularly in hospitals. Two-way learning was a feature. Providing transport, team home visits and employing Aboriginal staff improved access to care. Grandmothers successfully brought young pregnant women into the program through their community networks, and were able to positively influence healthy lifestyle behaviours for clients.Conclusion
Many elements of the Aboriginal Maternity Group Practice Program contributed to the provision of a culturally competent service. These features could be considered for inclusion in antenatal care models under development in other regions with culturally diverse populations. 相似文献30.
The problem of determining ridge estimates of the regression parameters in a two-input production function model,constrained to be non-negative,has been formulated as an exercise in quadratic programming. Relevant Kuhn-Tucker conditions have been derived and a small simulation studv has been carried out. 相似文献
