Qualitative interviews with nursing home administrators reveal innovative and cost-conscious ways to physically modify facilities that help institute culture change practices. Telephone interviews were conducted following a national survey of nursing home nursing directors and administrators. In this cross-sectional snapshot of administrator experiences, motivations for making facilities more home-like and less institutional and creative responses to challenges are described. State and corporate support and regulator encouragement are noted that help their reform efforts. Administrators note that small steps to create a more home-like environment can result in a positive impact that minimizes disruption to existing care processes. They describe how they respond to challenges, such as the physical plant and high costs, and note how comparative shopping, cost-conscious physical improvements, and continuous involvement of staff and residents contribute to successful efforts. Their examples illustrate novel ways to humanize long-term care facilities that other nursing homes can emulate. 相似文献

Although sociologists, demographers, and economists are generally agreed that economic independence enhances the likelihood that men will marry, there is disagreement concerning its effect on women. The view that economic independence weakens women's incentive to marry has probably been the most influential, although it has been subjected to few rigorous empirical tests with individual-level data. In the present paper we examine the predictors of forming a first cohabiting union, of progressing from this union to marriage, and of marrying without previously cohabiting by applying hazard regression to event-history data from the 1992 Swedish Family Survey, supplemented by earnings data extracted from the national taxation register. We test a battery of measures that reflect people's past, current, and potential attachment to the labour market. We find that the correlates of union formation for women are largely indistinguishable from the correlates of union formation for men, and that far from being less likely than other women to cohabit or to marry, women with a greater degree of economic self-sufficiency are more likely to do so. 相似文献

Allen et al.’s results depend on their inclusion of children whose family at the time of their grade retention is unknown, plus adopted and foster children whose selection process into families is unknown. Children whose family has been through upheavals or transitions are less likely to make good progress in school than children from stable families. Children raised by stable same-sex couples do remarkably well in school. 相似文献

In mid-demographic-transition, many Asian countries enjoyed a large demographic ‘dividend’: extra economic growth owing to falling dependant/workforce ratios, or slower natural increase, or both. We estimate the dividend, 1985–2025, in sub-Saharan Africa and its populous countries. Dependency and natural increase peaked around 1985, 20 years after Asia. The UN projects an acceleration of the subsequent slow falls but disregards slowish declines in young-age mortality and thus, we argue, overestimates future fertility decline. Even if one accepts their projection, arithmetical and econometric evidence suggests an annual, if not total, dividend well below Asia's. The dividend arises more from falling dependency than reduced natural increase, and could be increased by accelerating the fertility decline (e.g., by reducing young-age mortality) or by employing a larger workforce productively. Any dividend from transition apart, low saving in much of Africa (unlike Asia) means that, given likely natural increase, current consumption per person is unsustainable because it depletes capital per person. 相似文献

Alcohol use is pervasive in adolescence. Though most research is concerned with how friends influence drinking, alcohol is also important for connecting teens to one another. Prior studies have not distinguished between new friendship creation, and existing friendship durability, however. We argue that accounting for distinctions in creation–durability processes is critical for understanding the selection mechanisms drawing drinkers into homophilous friendships, and the social integration that results. In order to address these issues, we applied stochastic actor based models of network dynamics to National Longitudinal Study of Adolescent Health data. Adolescents only modestly prefer new friendships with others who drinker similarly, but greatly prefer friends who indirectly connect them to homophilous drinkers. These indirect homophilous drinker relationships are shorter lived, however, and suggest that drinking is a social focus that connects adolescents via proximity, rather than assortativity. These findings suggest that drinking leads to more situational and superficial social integration. 相似文献

Objectives: The purpose of this study is to explore barriers to the use, maintenance, and expansion of social supports in older adult methadone clients. Methods: The data for this analysis were derived from a qualitative study of the needs of aging methadone clients. Data were collected through face-to-face interviews with 24 methadone clients over the age of 50. Results: A lack of trust was identified as a principal barrier to the use, maintenance, and expansion of the social supports of older adult methadone clients. Causes of this mistrust include issues associated with aging, past traumatic experiences, and difficult personal relationships. Implications: These findings imply that addressing the issue of self isolation and recognizing the reason older adult methadone clients engage in this behavior is a key element in getting this specific population to use, maintain, and foster healthy social supports. A common phrase echoed throughout the interviews is that a person cannot trust anybody. Because of this mistrust, some clients keep to themselves by electing to self-isolate and decline to use, maintain, or foster new relationships. As a result, these individuals are less likely foster and/or engage in healthy social relationships, which are a key component of substance abuse treatment and abstinence maintenance. 相似文献
