This paper examines the effect of excessive mortgage indebtedness on health among homeowners using nine waves of the Health and Retirement Study from 1992 to 2008. Health status is measured by subjective well-being, number of depressive symptoms, and incidence of hypertension. Using average annual state-level home prices as an instrument, we attempt to identify the causal effect in an panel IV framework. Results from the panel IV estimations suggest that having a high mortgage loan to home value (LTV), defined as LTV at or above 80 %, leads to more depressive symptoms and a higher incidence of hypertension, but has no effect on subjective well-being. Since the results from panel estimations did not show that debt affects health, whether the panel IV results demonstrate a causal relationship depends critically on the exclusion assumption.  相似文献

The present study examined the effects of reading submission- and dominance-themed erotica on attitudes toward women and rape, ideal partner preferences, and subjective sexual arousal. Heterosexual male (n = 241) and female (n = 240) participants read one of three erotic stories depicting male dominance, female dominance, or no dominance, or a fourth nonerotic control story. First, we found that after reading about a sexually dominant man, women reported increased benevolent sexism compared to men, and men reported increased rape myth acceptance compared to women. Second, men and women showed a similar level of preference for partner dominance after reading about a sexually dominant woman. This was in contrast to the typical pattern revealed in all other conditions, whereby women were more likely to favor dominant partners relative to men. Finally, we found no evidence to support the hypothesis that the story describing male dominance would be the most arousing. Rather, all three erotic stories were equally sexually arousing compared to the control condition, and men and women did not differ in the extent to which the erotic stories aroused them. Theoretical and practical implications are discussed.  相似文献

Clinical studies aimed at identifying effective treatments to reduce the risk of disease or death often require long term follow-up of participants in order to observe a sufficient number of events to precisely estimate the treatment effect. In such studies, observing the outcome of interest during follow-up may be difficult and high rates of censoring may be observed which often leads to reduced power when applying straightforward statistical methods developed for time-to-event data. Alternative methods have been proposed to take advantage of auxiliary information that may potentially improve efficiency when estimating marginal survival and improve power when testing for a treatment effect. Recently, Parast et al. (J Am Stat Assoc 109(505):384–394, 2014) proposed a landmark estimation procedure for the estimation of survival and treatment effects in a randomized clinical trial setting and demonstrated that significant gains in efficiency and power could be obtained by incorporating intermediate event information as well as baseline covariates. However, the procedure requires the assumption that the potential outcomes for each individual under treatment and control are independent of treatment group assignment which is unlikely to hold in an observational study setting. In this paper we develop the landmark estimation procedure for use in an observational setting. In particular, we incorporate inverse probability of treatment weights (IPTW) in the landmark estimation procedure to account for selection bias on observed baseline (pretreatment) covariates. We demonstrate that consistent estimates of survival and treatment effects can be obtained by using IPTW and that there is improved efficiency by using auxiliary intermediate event and baseline information. We compare our proposed estimates to those obtained using the Kaplan–Meier estimator, the original landmark estimation procedure, and the IPTW Kaplan–Meier estimator. We illustrate our resulting reduction in bias and gains in efficiency through a simulation study and apply our procedure to an AIDS dataset to examine the effect of previous antiretroviral therapy on survival.  相似文献

The combination of mindfulness and adaptive leadership principles is a means by which a community mental health center has achieved program innovation and financial stability in an environment of decreased public funding. Mindfulness is present-oriented and reflective, is willing to cultivate uncertainty, and approaches operational and client care practices from a non-judgmental frame of mind. In addition, adaptive leadership, an approach developed by Ronald Heifetz and associates, considers crises to be opportunities and offers a set of guiding principles that help to direct the organization’s resilience while building mutual trust and creativity among administration, staff, and community. The case study focuses on how one community mental health center cultivates organizational agility in adversity, using mindfulness and adaptive leadership to guide the provision of resources for all stakeholders. As a result, staff members practice self-care at work, feel included in all administrative decisions, and participate in developing new and cost effective ways to serve the increasing needs of low-income clients in the midst of decreased funding. The relationship between administrators and clinicians is critical in creating a successful environment for serving clients.  相似文献

We analyze the effects of family capital on child behavior problems in the United States and Great Britain by comparing a longitudinal survey sample of 5- to 13-year-old children from the 1994 National Longitudinal Survey of Youth (N = 3,864) with a similar sample of children from the 1991 National Child Development Study "British Child" (N = 1,430). Findings suggest that in both societies, male children, those with health problems, and those whose mothers are divorced are at increased risk for behavior problems, while those with stronger home environments are at reduced risk. Family structure effects are more pervasive in Great Britain than in the United States, although some of these findings are a function of our racially diverse U.S. sample. We conclude that parents are important in both societies in promoting child social adjustment, and evidence that the more developed welfare state in Great Britain may substitute for capital at home is weak.  相似文献

Coordinating care for hospitalized patients requires the use of multiple sources of information. Using a macroergonomic framework (i.e. the work system model), we conducted interviews and observations of care managers involved in care coordination across transitions of care. When information is distributed across multiple health IT applications, care managers experience a range of challenges, including organizational barriers, technology design problems, skills and knowledge issues, and task performance demands (i.e. issues related to individual information processing and management and sharing of information). These challenges can be used as a checklist to evaluate the proposed IT infrastructure that will allow the integration of multiple health IT applications and, therefore, support coordination across transitions of care.  相似文献

This article proposes a method of conducting urban visual work – a practice-led visual study in which researcher-generated expressive photography explores the ‘city-as-archive’ (Hetherington 2013) and contributes to the urban visual archive. The photographs used in this article focus upon the social world of material remnants in the setting of the old downtown of Managua, Nicaragua. The aim of the article is four-fold: to suggest the epistemological gains of expressive photography, to discuss the methodology and style, to present the use of these images in an urban visual ethnography of Managua and to address related ethical concerns. Although expressive photographs are used to some extent by scholars, there is a noticeable lack of discussion of the method and empirical examples in urban visual studies. In this article, I propose intentionally using expressive photography to convey the subjective and affective knowledge that is generally not communicated by more conventional, ‘realist’ documentary visual techniques. Moving into a more explicit conversation of the work process, I point out three arenas for inquiry, for which this method can be useful. I detail my own visual ethnographic practice, and present my primary visual aims in three image clusters: expressive photography in conjunction with historical images, theorising the oscillation between absence and presence and visually interpreting the vernacular design of the ruinscape. The article concludes with a consideration of ‘ruin romance’ as an ethical concern, as well as some reflections over perceived difficulties in using this method as a means of doing academic research.  相似文献

ABSTRACT

The goal of this review is to discuss the state of the science in elder abuse prevention. Findings from evidence-based programs to reduce elder abuse are discussed, drawing from findings and insights from evidence-based programs for child maltreatment and domestic/intimate partner violence. A conceptual measurement model for the study of elder abuse is presented and linked to possible measures of risk factors and outcomes. Advances in neuroscience in child maltreatment and novel measurement strategies for outcome assessment are presented.  相似文献
