Do adult children affect the care elderly parents provide each other? We develop two models in which the anticipated behavior of adult children provides incentives for nondisabled elderly parents to increase care for their disabled spouses. The “demonstration effect” postulates that adult children learn from a parent’s example that family caregiving is appropriate behavior. The “punishment effect” postulates that adult children may punish parents who fail to provide spousal care by not providing future care for the nondisabled spouse if and when necessary. Thus, joint children act as a commitment mechanism, increasing the probability that elderly parents will provide care for their disabled spouses. We argue that stepchildren provide weaker incentives for spousal care because the attachment of a stepchild to a stepparent is likely to be weaker than the attachment of children to parents in a traditional nuclear family. Using data from the HRS, we find evidence consistent with the hypothesis that joint children provide stronger incentives than stepchildren for nondisabled elderly parents to provide care for their disabled spouse. 相似文献

In the last few decades, the prevalence of obesity has expanded rapidly and now constitutes a grave public health concern across the developed world. Obesity is negatively associated with, among other factors, education and healthcare quality, which are factors that governments can and do influence through welfare policies. This study investigated to what extent the change in the prevalence of obesity is lower in more generous welfare states. Based on pooled time series cross‐section regressions for 15 developed countries over 25 years, we found that the more generous are transfer payments, health policy and education policy, the lower is the increase of obesity prevalence. These findings have important implications for public policy formation and the public health and welfare state literatures. 相似文献

The office of Research Integrity has proposed a new definition of scientific misconduct that will substantively reduce the federal government's role of oversight of scientific practices. The standard is being changed despite the lack of evidence about the effects of current policies or understanding of why research misconduct occurs, how it can be detected and prevented, and the nature and effectiveness of sanctions. Given this lack of knowledge and the perception that the integrity of science is falling, we believe it would be unwise for the academic and scientific community to adopt this new standard. 相似文献

Communication targeting resource communities, sites of potentially damaging industries such as forestry, mining, and logging, requires an understanding of risk perceptions among residents living within these communities. Among concerns facing these communities is social stigmatization, an actual or feared negative psychological experience associated with living in a community with an undesirable industry. This study of a coal-mining resource community was conducted with the purpose of exploring a range of perceptions associated with ongoing exposure to a resource industry, including the experience of social stigma. This study used focus group interviews with stakeholders to highlight the personal voices of the resource community experience. A model of stakeholders' perceptions of industry risks and benefits is introduced, and important distinctions between hypothetical risk perceptions and perceptions of resource community stakeholders are explored. Implications for communicating with resource communities are also discussed. 相似文献

This study explored whether accountability influences the relationship between power and leader self-serving behavior. Across three studies, using both experimental manipulations and individual difference measures, we found that accountability mitigated the effects of power on leader self-serving behavior. Specifically, we found that powerful accountable leaders acted less self-servingly than their non-accountable counterparts. Moreover, as expected, low power leaders' behaviors were not affected as strongly by the explicit presence of accountability constraints. Overall, these results suggest that holding powerful leaders accountable for their actions could serve as a powerful tool to prevent potential self-serving actions on their part. 相似文献

Two years ago, the School of Social Work embarked upon a new and challenging initiative to create sustainable structural changes that enrich gerontological learning experiences for all our BSW and MSW students, faculty, fieldwork instructors and community practitioners. We envisioned that participation in this initiative would enable us to expand and embed geriatric content in the undergraduate and graduate curriculum, to increase our geriatric fieldwork placement opportunities, to evaluate and enhance our teaching and learning resources on aging, and to develop two new aging specific courses. Having reached our third year of operation, we find ourselves reflecting on what have been our successes, what could we have done differently, and where do we go in the future. This article will describe our process of developing a model of curriculum change that will guarantee a place for aging in both our undergraduate and graduate curricula. 相似文献

This paper presents the results of a Monte Carlo study of OLS and GLS based adaptive ridge estimators for regression problems in which the independent variables are collinear and the errors are autocorrelated. It studies the effects of degree of collinearity, magnitude of error variance, orientation of the parameter vector and serial correlation of the independent variables on the mean squared error performance of these estimators. Results suggest that such estimators produce greatly improved performance in favorable portions of the parameter space. The GLS based methods are best when the independent variables are also serially correlated. 相似文献
