Karine Torosyan Theodore P. Gerber Pilar Goñalons‐Pons 《The International migration review》2016,50(2):445-474
We examine whether migration affects the gender division of household tasks and participation in leisure within origin‐country households using survey data from the Republic of Georgia. Our theoretical framework identifies two sets of mechanisms whereby migration might influence gender differences in home activities: migrant experience effects and migrant absence effects. We test for both types of effects on the probability that men and women perform gender atypical household tasks and engage in leisure activities by comparing households with and without currently absent and return migrants using probit regressions. We find evidence for both migration absence and migration experience effects on gender differences in housework and leisure. However, these effects are complex and contradictory: Generally, male migration tends to exacerbate gender differences in the sending household while female migration tends to ameliorate them. 相似文献

This paper introduces several theoretical constructs drawn from the work of Humberto Maturana that can be applied to a diverse range of clinical contexts, including supervision. These constructs are: love as a fundamental need of human beings; pathways of explanation: (Objectivity), Objectivity; Emotioning; Structural Coupling; Plasticity; Domains of Operational Coherences. These constructs assist in choosing a point of entry for specific clinical situations and form a foundation on which one's preferred model of practice can be built. 相似文献

This is the first in an occasional series of DPR Debates, designed to illuminate specific issues of international development policy. Each debate will bring together two well‐known researchers or practitioners, giving them the opportunity, over three rounds, to test and challenge each other's ideas. The debates are intended to be robust but accessible, rooted in rigorous research but useful to the wide readership of Development Policy Review. 相似文献

Unlike states in Europe, East Asia settles very few migrants and has not developed a European‐style multicultural society. We seek to explain this variation using comparative analysis of two of the most advanced states in East Asia, South Korea and Japan, with several states in Europe. Focusing on family reunification – almost always the precursor to migrant settlement – we examine the effects of several independent variables, including supranational institutions, independent courts, interest groups, political culture, and the perceptions of migrants. We conclude that both Korea and Japan have less migrant settlement because of the lack of regional institutions pushing for family reunification rights, an elite political culture that still maintains the assumptions and repertoires of a “developmental state,” where rights may be sacrificed for economic growth and order, and migrant perceptions of greater immigration control in Asia. 相似文献

This study examined (a) growth curves of youth participation in sports, performance and fine arts, and youth clubs throughout the high school years and (b) the associations between a series of predictors and the initial participation rates and growth over time. The predictors included individual, friend, and family factors. The moderating effect of youths' gender was also examined. Study participants were 272 youths (55% girls, Mage=12.4 years) and their parents. The predictors were assessed in Grade 6 and were based on reports by youths, parents, teachers, and classmates. Participation in organized activities was assessed annually from Grades 7 to 10. Altogether, the findings revealed that participation in sports, performance and fine arts, and youth clubs remains stable across the high school years. However, interindividual differences were found in the participation growth curves. This variation was predicted by individual, friend, and family factors, mostly with respect to sports activities. 相似文献

This study describes the transition towards independent living of 123 former fostered young people reared for long periods in a private French organisation, SOS Children’s Villages. Three generations of care leavers were analysed through a postal survey and interviews. Their narratives show typical pathways after leaving care. Two‐thirds became independent without major problems by the age of 24–25. Analyses have shown that the absence of severe emotional and behavioural disorders, and diplomas obtained, improved their odds of becoming independent. Results suggest a vital need to implement appropriate therapeutic care during placement and to develop care leaver support well beyond the age of 18, in order to help them personally and academically and to ensure their successful transition to adulthood. 相似文献

It is rare that family members other than the identified patient are followed over time in studies of therapy effectiveness. Family therapy is believed to be effective because it targets processes within the system that maintain symptoms. If these processes are changed, then all family members can benefit. Using a sample of 183 mother–child dyads from a study comparing family therapy for adult substance use versus an attention control, change in child's substance use (tobacco, alcohol, and marijuana) was estimated. Children who participated in family therapy with their mothers showed greater decreases in alcohol and tobacco use and were less likely to begin using compared to children whose mothers participated in the attention control condition. 相似文献
