In this paper, we examine how Alzheimer's disease and related disorders (ADRD) affect caregivers' perceptions of change in the identity of their afflicted spouse and the ways in which accompanying changes in caregiver identity influence intimate relations. We also explore how gender shapes the ADRD caregiving experience among married couples, specifically, the extent to which intimate relations are also gendered relations. The study group was comprised of spousal caregivers recruited from support groups in the two Midwestern states and from the Alzheimer's Disease Center (ADC) at a large Midwestern university hospital. In-depth interviews were conducted with 13 men and 15 women whose spouses had ADRD. The intensive interviews confirmed that identity change on the part of sick spouses had important implications for intimacy, although not always in adverse ways. The majority of caregiver husbands and wives reported diminished intimacy as a result of the ADRD. Many men and women believed they would retain feelings of closeness to their afflicted spouses as long as they were alive. Wives were more likely than husbands to report that changes in their spouses' identity altered how they identified themselves within their marriage. This has important implications for intimate relations between people with ADRD and those who care for them. Our findings suggest that caregiving and intimacy are very different experiences for men and women, and point to the need for caregiver education and support.  相似文献

This study of communication in an Assisted Living Facility (ALF) focuses on staff's interpretive frameworks and situational tactics for managing elderly residents. It is based on interviews with staff and residents in an ALF together with ethnographic fieldwork. As in other quasi-total institutions, staff members engage in control as well as care, monitoring residents for compliance with rules and directives. Residents, aware of the threat of being moved to a nursing home, also monitor their own behavior and cognition in comparison to other residents. Other communication issues include the infantilization of the elderly by staff, and the race, class, and ethnic prejudices of residents.  相似文献

We describe the DNA collection processes of an initial pilot and full study, which is designed to investigate joint peer and genetic effects on health behaviors and attitudes in a college campus setting. In the main study, 2664 (79.5%) students completed a Web survey and 2080 (78.7% of the survey completers after adjusting for the ineligible) provided a saliva DNA sample. The response rate for completing both the survey and the DNA portion of the study is 62.5%. Our DNA yields are of high quality. Overall, our experiences and results demonstrate that genetic data can be successfully collected as a part of traditional social science survey research projects. To aid others in doing so, we provide extensive details of our data collection experiences and offer recommendations to future researchers seeking to do or evaluate similar work.  相似文献

This paper explores the effect of mortalities from the 1918 influenza pandemic and World War I on wage growth in the manufacturing sector of U.S. states and cities from 1914–1919. The hypothesis is that both events decreased manufacturing labor supply, thereby initially increasing the marginal product of labor and wages. The results reveal that states and cities having had greater influenza mortalities experienced higher wage growth—roughly 2–3 percentage points for a 10% change in per capita mortalities. World War I combat mortalities also had a positive, but smaller, effect on wage growth. ( JEL N62, N32, N92, I12)  相似文献

It is common to understand the governing of rural space as the outcome of a conflict between some romantic protectors of a lost past on the one hand, and the people who worry about creating economic values on the other. However, the power to shape the rural should not only be searched for in the open struggle between protectors and developers, but also should be analysed at the level of discourse, in the play between discourses about how to deal with the rural. In this paper I therefore present a modernist discourse and demonstrate how taken-for-granted truths about the rural – its history, its present and its future – are made possible by this discourse. Secondly, I will reveal how rurality takes on a different meaning in an alternative to the modernist discourse, emphasizing local and regional autonomy. In demonstrating that rurality is contingent upon a play between these two discourses, I want to provide some new insights into an important force behind the persistence of ideas about rurality in Norway.  相似文献

Anxiety disorders are among the most common psychiatric disorders in children and adolescents. Most empirically supported treatments (ESTs) for pediatric anxiety disorders include various cognitive-behavioral methods. Although demonstrated efficacious in controlled and clinic settings, there are barriers to implementing these types of therapies in social work settings due to beliefs about the usefulness of ESTs in community settings; limitations of treatment manuals; time constraints of implementing ESTs; fidelity and flexibility of implementing ESTs; and limited training opportunities. This article provides an overview of ESTs for childhood anxiety disorders, highlighting options for overcoming common barriers to implementing ESTs. Collaborative multi-method approaches to advance implementation of ESTs in social work practice are suggested.  相似文献

Public administration scholars often associate increased publicparticipation in policy implementation with the advancementof democratic values. Likewise, scholars engaged in the variousforms of action research (AR) promote their efforts as a meansto democratizing the research process or contributing to improvedsocial outcomes. Despite these common interests in participationand democracy, there have been few attempts to apply AR methodsto policy implementation problems. Drawing on Matland's conflict-ambiguitymatrix, we develop a framework for matching particular AR methodsto specific policy implementation contexts.  相似文献

The present paper develops and tests two temporal models of the relationships among adolescents' ethnic identity exploration, ethnic identity affirmation and belonging, and attitudes toward their racial/ethnic ingroup and outgroups. Structural equation models for Euro‐Americans, Asian Americans, and Latinos revealed that all hypothesized relationships were positive and significant. The model in which ethnic identity exploration (at Time 1) predicts ethnic identity affirmation and belonging (at Time 2) was superior to the alternative model in which the relationship between them was reversed (i.e., affirmation and belonging at Time 1 predicts exploration at Time 2). Results (1) support the importance of exploration as a basis for establishing a secure attachment to one's ethnic identity, which, in turn, has positive implications for attitudes toward one's own group and other groups and (2) suggest that maintenance of ethnic identity is compatible with positive attitudes toward ethnic outgroups.  相似文献

Urban development has profound impacts on ecological patterns and processes making the scientific information required for developing environmental ordinances central for mitigating these negative ecological impacts. Washington State requires that planners use the best available science (BAS) to formulate land use ordinances as part of the state’s Growth Management Act (GMA). We present empirical findings describing challenges to planners in defining “best available science” and using BAS to create local ordinances that balance development needs with natural resource protection. We interviewed city and county planners (and their consultants) in western Washington to determine what they find useful about BAS, whether or not BAS is applicable to their jurisdictions, and what constraints they experience in reviewing and using BAS to create or update their land use ordinances. Our results suggest that applying the BAS requirement is particularly difficult in urban areas. Specifically, planners had difficulty applying results from research conducted in systems dissimilar to their urban landscapes. These challenges to planners were exacerbated by (1) a lack of resources and (2) political tensions among stakeholders with competing values in urban settings. We conclude with recommendations for improving the consideration of science in statewide land-use planning.  相似文献
