Despite major demographic changes over the past 50 years and strong evidence that time spent with a spouse is important for marriages, we know very little about how time with a spouse has changed—or not—in the United States. Using time diary data from 1965–2012, we examine trends in couples’ shared time in the United States during a period of major changes in American marriages and families. We find that couples without children spent more total time together and time alone together in 2012 than they did in 1965, with total time and time alone together both peaking in 1975. For parents, time spent together increased between 1965 and 2012, most dramatically for time spent with a spouse and children. Decomposition analyses show that changes in behavior rather than changing demographics explain these trends, and we find that the increases in couples’ shared time are primarily concentrated in leisure activities. 相似文献

Using original survey data from Spain, this paper assesses the determinants of smoking behavior. This study examines the effect on smoking of the most diverse set of risk measures ever considered: lung cancer, relative lung cancer risks, lung disease, heart disease, relative heart disease risks, lost life expectancy to smokers, and various risk measures for passive smoking. Smoking measures include cigarette smoking, the number of cigarettes smoked, and pipe and cigar smoking. Primary smoking risks have a more consistent negative effect on smoking than perceived passive smoking risks. 相似文献

Research has shown that migration impacts youth outcomes, including educational performance and mental and physical health. It is, however, unknown whether differing patterns of mobility affect young people differently. This is because scholarship and policy-making on youth and migration simplify youth mobility by conceptualising youth either as immobile (when they ‘stay behind’ while their parents migrate) or as moving only once (when they follow parents or migrate independently). Between these extremes is the possibly more common phenomenon of youth who engage in sustained mobility patterns prior to, during, and after their first international move. This paper explores how youth mobility can be conceptualised to include the often-complex mobility patterns exhibited by youth in today’s global cities. Through an analysis of detailed mobility data collected using mixed methods among young Ghanaians growing up in and between the Netherlands and Ghana, we propose a typology of their mobility trajectories that highlights the variety of mobility patterns that youth engage in. Such a typology helps move research beyond the ethnic lens and rigid dichotomies between internal and international migration. We argue that the diversity of youth mobilities needs to be taken into account in order to understand how migration affects youth. 相似文献

Disability is a burden to individuals and society. Population ageing, combined with the fact that disability is most common among the elderly, has focused attention on trends in old-age disability. This study estimates trends in functioning and disability among Japanese elderly from 1993 to 2002 and contrasts the patterns with those found in the USA. Japan is an especially interesting country because its age structure is relatively old, and it currently has the highest life expectancy in the world despite the fact that just 50 years ago its life expectancy was in the bottom half of all countries. As in the USA, disability rates have fallen. If it were not for the gains in disability between 1993 and 2002, there would have been 1.1 million more disabled elderly in 2002. The reductions were experienced broadly across socio-demographic and economic groups. Increases in education across cohorts are associated with the declines in disability. 相似文献

Beliefs about child competence in math and reading have important implications for academic performance in adolescence. However, it is unclear whether children's own beliefs are the most important predictor of their academic performance or whether parents’ and teachers’ beliefs about child competence influence child academic performance. We assessed mothers’, fathers’, teachers’, and children's beliefs about European American children's (N = 189) competence in math and reading at age 10 and children's math and language performance at ages 10, 13, and 18 years. Confirmatory factor models demonstrated that children's and teachers’ beliefs had lower loadings on a latent variable of child competence in math and reading than mothers’ beliefs. Children's self‐competence beliefs in math and reading were not significantly correlated, suggesting children may use dimensional comparisons when assessing their own competence. Mothers’, fathers’, and teachers’ assessments of child competence in math were strongly correlated with their assessments of child competence in reading. Controlling for stability in academic performance, family socioeconomic status, and other reporters, mothers and fathers who rated their children's math competence higher had adolescents who performed better in math, and fathers who rated their children's reading competence higher had adolescents who performed better in language tasks. However, children who rated their own competence higher in math and reading had lower math and language (for girls only) performance in adolescence. European American children may use dimensional comparisons that render them poorer judges of their math and reading competence than parents. 相似文献

A conceptual framework for examining the promise of the NORC program and Village models to promote aging in place 总被引:1,自引:0,他引:1

A growing paradigm shift emphasizes efforts to promote aging in place not only by helping aging individuals and families, but also by addressing and engaging communities. This paper explores the idea of developing community supports for aging in place by examining two models that incorporate this approach into practice: Naturally Occurring Retirement Community Supportive Service Programs (NORC programs) and Villages. Drawing on research regarding social–relational aspects of communities and later-life health and well-being, we present an integrative conceptual framework positing three categories of activities and services (civic engagement and empowerment activities; social relationship building activities; services to enhance access to resources)–as well as the initial outcomes and intermediate outcomes–through which the NORC program and Village models potentially achieve their long-term goal of promoting aging in place. Based on this framework, we conclude with directions for future research on community initiatives that support aging in place. 相似文献

This article examines the ways in which employers in the Australian aged care sector justify and sustain low pay for work that is both highly skilled and in high demand. We build on a large body of feminist research that analyses why care work is devalued by showing how such devaluing is produced at the level of the organization. To do so we examine some of the specific discursive mechanisms that sustain low pay. We show that aged care employers actively reproduce a familial logic of care that represents paid aged care work as unskilled and natural for women and therefore not deserving of higher pay. We argue that in order to achieve their goals employers must develop and sustain an opposition between care as love‐centred and work as money‐centred, while upholding the notion that they provide quality care for care recipients. 相似文献

Betancourt LM Brodsky NL Brown CA McKenna KA Giannetta JM Yang W Romer D Hurt H 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2012,28(2):225-238
Our objectives for this report were to identify trajectories of youth gambling behavior, and to examine their relation to
executive cognitive function (ECF) and associated problem behaviors. Philadelphia school children, enrolled at ages 10–12 years
(n = 387; 49% male), completed three annual assessments of risk behaviors, ECF, impulsivity, problem behaviors and demographics.
Across ages 10–15 years, using methods from Nagin et al., two groups were identified: Early Gamblers (n = 111) initiated early and continued in later assessments, and Later Gamblers (n = 276) initiated at later ages and gambled less. Betting money on cards and sports were the most frequently reported gambling
behaviors. Using gambling group as outcome, final backward selection logistic regression model showed Early Gamblers are more
likely male (P = 0.001), report more active coping (P = 0.042), impulsive behaviors (P ≤ 0.008), and have friends who gamble (P = 0.001). Groups were similar in ECF, parental monitoring, marital status, SES, and race. Early Gamblers had higher incidence
of problem behaviors and drug use (all P ≤ 0.006). Two gambling groups were identified in early adolescence with Early Gamblers showing higher levels of impulsivity
and comorbid problems but similar levels of ECF compared to Late Gamblers. As more gambling groups are identified through
later adolescence, ECF may emerge as a relevant precursor of problem gambling at this later time. 相似文献

Few after‐school programs target alcohol and other drug (AOD) use because it is difficult to encourage a diverse group of youth to voluntarily attend. The current study describes CHOICE, a voluntary after‐school program which targeted AOD use among middle school students. Over 4,000 students across eight schools completed surveys and 15% participated in CHOICE. Analyses indicated that there were some differences between CHOICE participants and nonparticipants. For example, African American and multiethnic students were more likely to attend. Past month alcohol users were more likely to initially attend, and marijuana users were more likely to continue attendance. Thus, CHOICE reached students of different racial and ethnic groups and attracted higher risk youth who may not typically obtain prevention services. 相似文献
