The economic benefits to immigrants of taking jobs in ethnic workplaces, relative to the open economy, are heavily debated. We examine longitudinally differences across immigrant categories in how the choice of ethnic or non‐ethnic workplace influences the ethnic composition of social networks and how these factors impact immigrants’ economic success. Using the Longitudinal Survey of Immigrants to Canada, with data 6 months, 2 years, and 4 years after arrival, we find support for both sides of the ethnic economy debate when it is qualified by immigrant category. While economic immigrants benefit from non‐ethnic workplaces, family immigrants face economic penalties in the open economy and do better in ethnic workplaces. We argue that policies sorting immigrants into visa categories do much of the work of leading them into segmented paths of incorporation. 相似文献

A three-parameter F approximation to the distribution of a positive linear combination of central chi-squared variables is described. It is about as easy to implement as the Satterthwaite-Welsh and Hall-Buckley-Eagleson approximations. Some reassuring properties of the F approximation are derived, and numerical results are presented. The numerical results indicate that the new approximation is superior to the Satterthwaite approximation and, for some purposes, better than the Hall-Buckley-Eagleson approximation. It is not quite as good as the Gamma-Weibull approximation due to Solomon and Stephens, but is easier to implement because iterative methods are not required. 相似文献

There is considerable diversity in the literature regarding age and gender differences on career maturity and career decision status. There is also a dearth of data on high school samples. The present study reports cross‐sectional data from 1,971 Australian adolescents, ages 12.51‐17.99 years, who completed the Career Decision Scale (S. H. Osipow, C. G. Carney, J. Winer, B. Yanico, & M. Koschier, 1976) and the Career Development Inventory (Australian; J. Lokan, 1984). Results illustrated a developmental progression in career maturity, although a less uniform pattern emerged with gender differences. Findings regarding career indecision also presented a complex picture and highlight the need to focus on other demographic and contextual factors. 相似文献

Major natural disasters in recent years have had high human and economic costs, and triggered record high postdisaster relief from governments and international donors. Given the current economic situation worldwide, selecting the most effective disaster risk reduction (DRR) measures is critical. This is especially the case for low‐ and middle‐income countries, which have suffered disproportionally more economic and human losses from disasters. This article discusses a methodology that makes use of advanced probabilistic catastrophe models to estimate benefits of DRR measures. We apply such newly developed models to generate estimates for hurricane risk on residential structures on the island of St. Lucia, and earthquake risk on residential structures in Istanbul, Turkey, as two illustrative case studies. The costs and economic benefits for selected risk reduction measures are estimated taking account of hazard, exposure, and vulnerability. We conclude by emphasizing the advantages and challenges of catastrophe model‐based cost‐benefit analyses for DRR in developing countries. 相似文献

We examined the contribution of relational aggression in adolescents' peer and dating relationships to their psychological and behavioral adjustment. In the Fall and again four months later, 1279 (646 female) grade 9 students reported on relational aggression perpetration and victimization in their romantic and peer relationships, depression/anxiety symptoms (psychological adjustment) and delinquency (behavioral adjustment). Using hierarchical regression analyses, controlling for Time 1 adjustment/behavior, peer relational aggression perpetration predicted depression/anxiety. Dating relational victimization also predicted depression/anxiety, but only for girls. Furthermore, girls who were perpetrators of relational aggression in both peer and dating contexts were most likely to show increases in delinquent behavior. We conclude that dating and peer relationships are not redundant, but make independent and additive contributions to adolescent adjustment. Girls, in particular, may be at greatest risk for poor outcomes when they have relationally aggressive relationships. Results also highlight the need for greater awareness of the complexity and significance of adolescent dating relationships. 相似文献

The main goal of this study was to examine the direct and moderating effects of trustworthiness and modeling on adolescent siblings' adjustment. Data were collected from 438 families including a mother, a younger sibling in fifth, sixth, or seventh grade (M = 11.6 years), and an older sibling (M = 14.3 years). Respondents completed Web‐based surveys describing sibling conflict and warmth. Siblings reported on trustworthiness and modeling, and mothers described adjustment. Sibling conflict was directly associated with internalizing and externalizing behaviors for both siblings. The older siblings' reports of trustworthiness were directly associated with the outcome measures. The younger siblings' reports of trustworthiness were less directly associated, but a possible salutary effect was most evident under the highest levels of sibling conflict or warmth. Higher sibling modeling was a risk factor for adjustment problems in relations characterized by high conflict. Results support exploring trustworthiness as a key dimension of sibling relations. 相似文献

E-mail: david.pentecost{at}lineone.net Summary Four hundred and forty social work practitioners for children,including those of Guardian ad Litem status, were surveyed regardingtheir knowledge and perceptions concerning attention deficithyperactivity disorder (ADHD). Questionnaires were distributedto the social workers via managers in seven boroughs in thesouth-east of England. The majority of practitioners in thesample were able to correctly identify the key diagnostic criteriaclosely associated with the condition. Over a third of respondentswere unsure of the appropriateness of treatment with stimulantmedication while the large majority felt that psychosocial interventionsinvolving the families were appropriate. Length of post-qualifyingexperience was found to be a crucial variable influencing bothknowledge about ADHD and the preferences for interventions forthe condition. Less than three out of ten practitioners regardedit as important to involve the Children with Disabilities Teams(CDTs) in such cases and a similar proportion were unaware oflocal resources that may support these children and their families.The results are discussed in relation to previous studies, implicationsfor social work practice and training and the role of CDTs inthe field. 相似文献
