This article examines trends in family attitudes and values across the last 4 decades of the 20th century, with particular emphasis on the past 2 decades. The article focuses on attitudes toward a wide range of family issues, including the roles of men and women, marriage, divorce, childlessness, premarital sex, extramarital sex, unmarried cohabitation, and unmarried childbearing. More generally, the article considers trends in 3 broad contemporary values: freedom; equality; and commitment to family, marriage, and children. Five data sets are used for the article: Monitoring the Future, General Social Survey, International Social Science Project, Intergenerational Panel Study of Parents and Children, and the National Survey of Families and Households. These 5 data sets reveal substantial and persistent long‐term trends toward the endorsement of gender equality in families, which may have plateaued at very high levels in recent years. There have also been important and continuing long‐term trends toward individual autonomy and tolerance toward a diversity of personal and family behaviors as reflected in increased acceptance of divorce, premarital sex, unmarried cohabitation, remaining single, and choosing to be childless. At the same time, marriage and family life remain important in the cultural ethos, with large and relatively stable fractions of young people believing that marriage and family life are important and planning marriage and the bearing and rearing of children.  相似文献

Refugee research has tended to focus exclusively on the mental health consequences of migration with little attention being devoted to factors that facilitate adjustment. Recently, several cross‐cultural researchers have suggested that the growing literature on moderators of stress may elucidate why some migrants experience adverse effects whereas others remain relatively unscathed. This study examines the moderating effects of social and personal resources on the relationship between stress and subjective well‐being in 60 recently‐arrived and 60 established Salvadoran refugees in Canada. The participants completed a questionnaire that included scales pertaining to stress (life events, hassles, migration‐related events), resources (social support, locus of control, self‐esteem) and well‐being (quality of life, life satisfaction). Varying results were found for both groups. For Recent Refugees, personal resources were found to moderate migration stress. In particular, locus of control buffered the relationships between migration stress and quality of life and life satisfaction, whereas self‐esteem buffered the migration stress‐quality of life relation. For Established Refugees, social support and self‐esteem moderated the relationship between life events and life satisfaction. In addition, social support buffered the effects of hassles on quality of life. The findings underscore the relevance of integrating more firmly the study of refugee adjustment with current developments in stress research.  相似文献

We show that, in the context of double-bootstrap confidence intervals, linear interpolation at the second level of the double bootstrap can reduce the simulation error component of coverage error by an order of magnitude. Intervals that are indistinguishable in terms of coverage error with theoretical, infinite simulation, double-bootstrap confidence intervals may be obtained at substantially less computational expense than by using the standard Monte Carlo approximation method. The intervals retain the simplicity of uniform bootstrap sampling and require no special analysis or computational techniques. Interpolation at the first level of the double bootstrap is shown to have a relatively minor effect on the simulation error.  相似文献

This paper examines the determinants of base pay and total incentive compensation packages of CEOs of biopharmaceutical firms that have recently gone public, and whether human capital and agency factors affect the market’s response to the initial public offering. We find that in terms of net proceeds, the IPO market appears to reward the firms that have founder-CEOs and CEOs with higher incentive compensation. CEOs with prior venture capital experience are associated with receiving higher incentive compensation, while CEOs with a greater ownership interest in the firm receive lower incentive compensation but higher salaries. CEOs of firms with a greater percentage of insiders are associated with lower salaries. The results should add to our understanding related to human capital and agency theories, as well as help firms and investors better understand and structure CEO compensation.  相似文献

Aquatic non‐native invasive species are commonly traded in the worldwide water garden and aquarium markets, and some of these species pose major threats to the economy, the environment, and human health. Understanding the potential suitable habitat for these species at a global scale and at regional scales can inform risk assessments and predict future potential establishment. Typically, global habitat suitability models are fit for freshwater species with only climate variables, which provides little information about suitable terrestrial conditions for aquatic species. Remotely sensed data including topography and land cover data have the potential to improve our understanding of suitable habitat for aquatic species. In this study, we fit species distribution models using five different model algorithms for three non‐native aquatic invasive species with bioclimatic, topographic, and remotely sensed covariates to evaluate potential suitable habitat beyond simple climate matches. The species examined included a frog (Xenopus laevis), toad (Bombina orientalis), and snail (Pomacea spp.). Using a unique modeling approach for each species including background point selection based on known established populations resulted in robust ensemble habitat suitability models. All models for all species had test area under the receiver operating characteristic curve values greater than 0.70 and percent correctly classified values greater than 0.65. Importantly, we employed multivariate environmental similarity surface maps to evaluate potential extrapolation beyond observed conditions when applying models globally. These global models provide necessary forecasts of where these aquatic invasive species have the potential for establishment outside their native range, a key component in risk analyses.  相似文献

Historically, the life course has been constructed as an organized and linear temporal progression. This holds true in various disciplines from education, to psychology, to counseling. The foundation of a life unfolding through temporal categorizations is documented in textbooks and theories that straddle these disciplines as well as many others, including the sociology of health and illness, which has often conceptualized the illness experience as embedded in a recovery trajectory.Here, we take this to task. Using Gubrium and Holstein's [Sociol. Inq. 65 (1995) 207; Gubrium, J., & Holstein, J., (1997). The new language of qualitative method. New York: Oxford University Press] analytic vocabulary of biographical work, we analyze narratives of stroke survivors by emphasizing the ordinary resources used as discursive foundations for the narrative production of the future in illness. Ordinary resources focused on include God and spirituality, comorbidities, and activity and leisure. The discussion is embedded in overarching concerns with “healthy aging” in gerontology and geriatrics.  相似文献
