ABSTRACT Research suggests that efficacy and empowerment are necessary for social engagement and that a sense of efficacy and empowerment exerts positive influences on older adults. However, little is known about how individual efficacy and empowerment are affected by group efficacy and empowerment in later life. To assess the impact of group involvement on the individual, the authors conducted a follow-up study with members of an art guild for older adults. Qualitative data were collected in 1997 and 2001 to ascertain the members' perceptions of group goals and accomplishments, membership benefits, the effect on the community, societal views about older adults, and the impact of group activities on the individual. The results clearly indicated that collective efficacy and empowerment through social engagement were beneficial to members as individuals and as a group, and contributed to well-being through a general sense of accomplishment and pride. 相似文献

ABSTRACT This is the first published account of state administrative code variations in nursing home social worker qualifications. It is important to review state codes because the majority of nursing homes in the U.S. have fewer than 121 beds and therefore are not required by the federal government to employ at least one full-time qualified social worker. States have the option of extending the federal regulations to homes with 120 or fewer beds, or strengthening the federal requirements in other ways. Findings indicate enormous variation in state requirements for qualifications of nursing home social workers, and even when states define a qualified nursing home social worker (not all do), they often exempt facilities from employing one. Seven states were found to be out of federal compliance. Research describing the qualifications of people employed in nursing home social services is called for, as well as research documenting effective psychosocial interventions, especially as they relate to resident quality of life. Ten recommendations for enhancing nursing home social work services are included. 相似文献

In addition to outlining criteria for the approval of human subjects research, federal regulations provide guidance regarding local institutional review board (IRB) membership. IRBs are mandated to include “at least one member whose primary concerns are in nonscientific areas” and “at least one member who is not otherwise affiliated with the institution.” Often a single individual serves both of these roles simultaneously. Although there have been calls for increased representation of lay community members on IRBs, little is known regarding their experiences or their perceptions of human subject protections and the IRB process. Using an ethnographic interview approach, this study seeks to gain a perspective from non-affiliated, non-scientist (NA/NS) IRB members about the process in which they participate. Findings suggest a need for clarification regarding whom NA/NS IRB members represent. They also suggest that NA/NS IRB members’ experiences could be improved by an increased show of respect from the IRB chair, other members, and staff; efforts to make participation more convenient for these volunteer members; and training tailored specifically to NA/NS members. Further research on this important and understudied topic is needed to determine best practice and policy recommendations. 相似文献

ABSTRACTThis article offers a new perspective on what it meant to be a business proprietor in Victorian Britain. Based on individual census records, it provides an overview of the full population of female business proprietors in England and Wales between 1851 and 1911. These census data show that around 30% of the total business population was female, a considerably higher estimate than the current literature suggests. Female entrepreneurship was not a uniform experience. Certain demographics clustered in specific trades and within those sectors employers and own-account proprietors had strikingly different age, marital status and household profiles. A woman’s life cycle event such as marriage, motherhood and widowhood played an important role in her decision whether to work, the work available to her and the entrepreneurial choices she could make. While marriage and motherhood removed women from the labour force, they had less of an effect on their levels of entrepreneurship. Women who had young children were more entrepreneurial than those who had none, and entrepreneurship rates rose with the arrival of one child and continued to rise the more children were added to the family. 相似文献

The study of sleep has been neglected within sociology, yet may provide insights into fundamental aspects of the nature of gender inequalities. This article examines how, for couples with children, sleep is influenced by the gendered nature of caring. A key concern is not only who gets up to care for children's physical needs at night, but whether this changes with women's increased role in the labour market. Of concern also is how changes in the nature of caring for older children, as opposed to young children, may impact on parents' sleep. This article analyses qualitative data from an ESRC funded multi-disciplinary project on couples' sleep based on in-depth audio-tape recorded interviews with 26 couples (aged 20-59) with younger and older children. Additionally, one week's audio sleep diaries were completed and follow up in-depth interviews were undertaken with each partner on an individual basis. Physical and emotional care for young children at night was largely provided by women, with a lack of explicit negotiation between partners about who provides this care, even when women return to employment. Thus, considerably more women than men continued their daytime and evening shifts, as well as undertaking an ongoing third shift of sentient activity for their family, into the night. This resulted in a fourth night-time shift where physical caring, and sentient activities continued. As a consequence, women were more likely to subjugate their own sleep needs to those of their family. Fathers did not, in general, undertake this fourth night-time shift. Those that did were more likely to be the fathers of young adult children who were staying out late at night, with the focus of their concerns being the safety of their children. 相似文献

The life course perspective emphasizes that past economic experiences and stage in the life course influence a family's ability to cope with negative life events such as poor health. However, traditional analytic approaches are not well-suited to examine how the impact of negative life events differs based on a family's past economic experiences, nor do they typically account for the potentially spurious association between negative life events and family economic well-being. We use finite mixture modeling to examine how changes in parental health affect children's exposure to poverty. We find that for some children the association between family head's health and children's exposure to poverty is spurious, while for other children family head's poor health is associated with increased risk of economic deprivation. The extent to which a family head's poor health alters children's economic well-being depends on a child's family's underlying economic trajectory and past history of exposure to disadvantage. 相似文献

The concept of quality of life (QOL) is increasingly being used in the field of intellectual disabilities as a conceptual and measurement framework for program planning and evaluation. This article describes the development of a QOL conceptual and measurement framework, and summarizes how this framework is currently being used both nationally and internationally to assess and report personal QOL-related outcomes, to guide quality improvement strategies, and to evaluate the effectiveness of those strategies. Implications of such use are discussed, including those related to understanding mental models, developing internal data systems, supporting organization change, and building on current public policies. The article concludes with reference to the evolving nature of the QOL concept and the impact of this on model development and transdisciplinary research. 相似文献

OBJECTIVE AND PARTICIPANTS: The authors investigated the effect of physical activity (PA), fruit and vegetable intake, and alcohol use on 6-month weight change in 193 college freshmen (78.8% white, 88.2% women, 94.5% on a meal plan). METHODS: The authors administered a Web-based survey in fall 2002 (baseline) and spring 2003 (follow-up). RESULTS: There was an overall average weight gain of 2.5 lbs (p < .05), although only 57% reported weight gain (M = 7.1 lbs). Fruit and vegetable intake decreased (p = .034), alcohol use increased (p > .05), and PA was unchanged. Weight gain for students with body mass indexes (BMI) > or =25 kg/m2 was nearly twice that of students with BMIs < 25 (p < .05). Students with low-frequency baseline PA were twice as likely to be overweight. Follow-up data showed that students reporting > or = 4 sessions per week (ie, high frequency) of low-intensity PA were twice as likely to have healthy BMIs as students engaging in low- and moderate-frequency PA. CONCLUSIONS: PA interventions should target freshmen with BMIs > or = 25. 相似文献
