Doing Well vs. Feeling Well: Understanding Family Dynamics and the Psychological Adjustment of Chinese Immigrant Adolescents 总被引:1,自引:1,他引:0
Desirée Baolian Qin 《Journal of youth and adolescence》2008,37(1):22-35
Despite their average high levels of educational achievement, Asian American students often report poor psychological and
social adjustment, suggesting an achievement/adjustment paradox. Yet, the reasons for this paradox remain unclear. Drawing
on 5-year longitudinal qualitative interview data, this paper compares the family dynamics of two groups of adolescents from
Chinese immigrant families: non-distressed adolescents (n = 20) who have high levels of academic achievement and high levels of psychological well-being; and distressed adolescents (n = 18) who have high levels of academic achievement but low levels of psychological well-being. Findings suggest that the
two groups of families differed in parenting approaches after migration, parent–child communication, parental expectations,
and parent–child relations. Implications for Asian American adolescent and youth development are discussed.

Little research has examined the consequences of a suicide for social or family networks. Because suicide occurs within families, the focus on the aftermath of suicide within families is an important next step to determine exactly how to help survivors. In this article, we review and summarize the research on the impact of suicide on individuals within families and on family and social networks. We begin with a discussion of family changes following suicide. Next, we discuss the effects of suicide on social networks overall and responses of children and the elderly to a suicide in the family. Finally, we identify key issues that remain to be resolved in family survivor research and make recommendations for future studies. 相似文献

Visas and work permits: Possible global negotiating initiatives 总被引:1,自引:0,他引:1
We discuss global options for initiatives intended to ameliorate adverse impacts of visa and work permit systems used by national
governments around the world. We first describe and document some of their effects, noting the relative lack of other research
work on these issues. We then discuss proposals for a new and supplemental global visa structure which have been made as part
of the Mode 4 GATS negotiations in the WTO, suggesting that the GATS/WTO may be an imperfect institutional location for negotiating
on these matters. We then evaluate other approaches, including what realistically could be possible if a new body specifically
created for global negotiation in the area were to be used.

The use and non-use of policy appraisal tools in public policy making: an analysis of three European countries and the European Union 总被引:1,自引:0,他引:1
Måns Nilsson Andrew Jordan John Turnpenny Julia Hertin Björn Nykvist Duncan Russel 《Policy Sciences》2008,41(4):335-355
The increasing complexity of policy problems, coupled with the political desire to base new policies on the foundation of firm evidence, has accelerated the development of policy assessment tools. These range from complex computer models and cost benefit analysis through simple checklists and decision trees. In the last decade, many governments have established formal policy assessment systems to harness these tools in order to facilitate more evidence-based policy making. These tools are potentially widely available, but to what extent are they used by policy makers and what becomes of the evidence that they generate? This paper addresses these questions by studying the empirical patterns of tool use across 37 cases in three European countries and the European Commission. It uses a simple classification of tools into advanced, formal and simple types. It finds that even when tools are embedded in policy assessment systems, their use is differentiated and on the whole very limited, in particular when it comes to more advanced tools. It then explores these patterns from contrasting theoretical perspectives to shed light on why, when and how different policy assessment tools are used in the policy process. 相似文献

This paper presents a theoretical framework and some empirical results showing that the level of foreign aid received reduces the supply of terrorist attacks by recipient countries, as does the recipient country’s level of education. Due account is taken of endogeneity problems in producing these results. They suggest that Western democracies, which are the main targets of terrorist attacks, should invest more funds in foreign aid with a special emphasis on supporting education. 相似文献
