School-aged children with an ethnic minority background are relatively often involved in bullying and victimization, but the role of ethnic composition of schools in this context remains unclear. This study examined the relation between ethnic minority background, ethnic school composition, and bullying behaviour around primary school entry in the Netherlands. The study was based on a 2008/2009 school survey in Rotterdam, a Dutch city where about 50 % of children have a non-Dutch background. For 8523 children, teacher reports of bullying behaviour at age 5–6 years were available. Children with a non-Dutch background had higher odds of being a victim (adjusted OR 1.41, 95 % CI 1.11, 1.80), bully (OR 1.38, 95 % CI 1.20, 1.58) or bully-victim (OR 1.38, 95 % CI 1.19, 1.62) than children of Dutch national origin. Ethnic diversity in schools increased children’s risk of bullying behaviour (e.g. ORvictim per 0.1 increase in 0–1 diversity range = 1.06, 95 % CI 1.00, 1.13), with children of both Dutch and non-Dutch national origin relatively more often involved in bullying in ethnically diverse schools. The proportion of same-ethnic peers in school reduced the risk of bullying among children of Dutch national origin (e.g. ORvictim per 10 % more same-ethnic children = 0.90, 95 % CI 0.83, 0.98), but not among non-Dutch children. In conclusion, ethnic minority background and ethnic diversity within schools are risk factors for bullying among 5–6 year olds. Plausibly, reductions in absolute numbers of bullying events may be obtained with tailor-made interventions in ethnically diverse schools. Such interventions should preferably be offered early in the school curriculum.  相似文献

Using data from the 2013 Survey of Consumer Finances, this research examines competing and complementary cultural and structural explanations of the sources of racial differences in wealth. We use OLS regression and quantile regression to identify the major individual-level sources of wealth differences between African Americans and whites. Whites have more favorable wealth characteristics than do African Americans on all of the variables in the analysis: gender of household head, bankruptcies, spending patterns, stock ownership, business ownership, home ownership, inheritance, educational attainment, income, occupation, age, and number of children. Cultural factors, having a female-headed family, spending patterns, and inheritance account for little of the racial wealth gap. Racial differences in income, stock ownership, and business ownership account for much of the explained racial wealth gap. Moreover, compared with whites, African Americans receive significantly lower wealth returns to education, age, income, stock ownership, and business ownership. We discuss the implications of our findings.  相似文献

Unfortunately many of the numerous algorithms for computing the comulative distribution function (cdf) and noncentrality parameter of the noncentral F and beta distributions can produce completely incorrect results as demonstrated in the paper by examples. Existing algorithms are scrutinized and those parts that involve numerical difficulties are identified. As a result, a pseudo code is presented in which all the known numerical problems are resolved. This pseudo code can be easily implemented in programming language C or FORTRAN without understanding the complicated mathematical background. Symbolic evaluation of a finite and closed formula is proposed to compute exact cdf values. This approach makes it possible to check quickly and reliably the values returned by professional statistical packages over an extraordinarily wide parameter range without any programming knowledge. This research was motivated by the fact that a very useful table for calculating the size of detectable effects for ANOVA tables contains suspect values in the region of large noncentrality parameter values compared to the values obtained by Patnaik’s 2-moment central-F approximation. The cause is identified and the corrected form of the table for ANOVA purposes is given. The accuracy of the approximations to the noncentral-F distribution is also discussed. The authors wish to thank Mr. Richárd Király for his preliminary work. The authors are grateful to the Editor and Associate Editor of STCO and the unknown reviewers for their helpful suggestions.  相似文献

Modeling firms in the global economy   总被引:1,自引:0,他引:1  
I examine the apparent deverticalization of firms in the world economy and their adoption of relational contracting and modularization, necessitated by rapid product change, cheap and rapid transport, and new technologies. I argue that relational contracting is superseded by modularization when possible in the interest of more control over suppliers, and modularization in turn leads to consolidation, when possible, through buying up suppliers or making them captives. The result is increased concentration of economic power in the world economy, and examples of this are presented.

The burgeoning literature on transborder membership, largely focused on the thickening relationship between emigration states in the South and the postwar labor migrant populations and their descendants in North America or Western Europe, has not paid due attention to the long-term macroregional transformations that shape transborder national membership politics or to the bureaucratic practices of the state that undergird transborder claims-making. By comparing contentious transborder national membership politics in South Korea during the Cold War and Post-Cold War eras, this article seeks to overcome these limitations. In both periods, the membership status of colonial-era ethnic Korean migrants in Japan and northeast China and their descendants was the focus of contestation. The distinctiveness of the case—involving both a sustained period of colonial rule and a period of belated and divided nation-state building interwoven with the Cold War—highlights the crucial importance of three factors: (1) the dynamically evolving macro-regional context, which has shaped transborder national membership politics in the region in distinctive ways; (2) the essentially political, performative, and constitutive nature of transborder nation-building; and (3) the role of state registration and documentation practices in shaping the contours of transborder national membership politics in the long run. By incorporating Korea—and East Asia more broadly—into the comparative study of transborder nation-building, this article also lays the groundwork for future cross-regional comparative historical studies.

The current crisis of neoliberalism is calling into question the relevance of key international institutions. We analyze the origins, nature, and possible impacts of the crisis through comparing two such institutions: the International Monetary Fund (IMF) and the World Trade Organization (WTO). Both originated in the post-World War II U.S.-led hegemonic order and were transformed as part of the transition to global neoliberalism. We show that while the IMF and the WTO have been part of the same hegemonic project, their distinct institutional features have put them on significantly different trajectories. Historical differences in the two institutions’ systems of rules have placed the IMF in a more vulnerable position than the WTO, which provides clues to the future contours of global economic governance.

Anxiety disorders are among the most common psychiatric disorders in children and adolescents. Most empirically supported treatments (ESTs) for pediatric anxiety disorders include various cognitive-behavioral methods. Although demonstrated efficacious in controlled and clinic settings, there are barriers to implementing these types of therapies in social work settings due to beliefs about the usefulness of ESTs in community settings; limitations of treatment manuals; time constraints of implementing ESTs; fidelity and flexibility of implementing ESTs; and limited training opportunities. This article provides an overview of ESTs for childhood anxiety disorders, highlighting options for overcoming common barriers to implementing ESTs. Collaborative multi-method approaches to advance implementation of ESTs in social work practice are suggested.  相似文献

Children living in foster care are an especially vulnerable population who often come to the attention of Medicaid mental health providers. These children experience a high incidence of emotional and behavioral disorders and may have specialized treatment needs related to their living arrangement status. This study assessed whether Children’s Psychosocial Rehabilitation could effectively treat youth with severe emotional and behavioral disorders who live in foster care. Analysis of data from an open trial of 218 clinically-impaired youth, aged 3–18 years, revealed no reliable differences in treatment outcome between foster versus non-foster children, with a trend toward more favorable outcomes for foster youth. Findings justify further study of the effectiveness of this Medicaid-funded service for the treatment of youth in care.  相似文献

Social workers are becoming increasingly aware of the unique experiences faced by children of incarcerated parents. Little is known, however, about their experiences prior to their parents being incarcerated. Using data from a broader study of incarcerated women, we examined women’s accounts of their children’s exposure to violence prior to maternal incarceration. Open-ended interviews addressed family and relationship history, physical and psychological victimization, lifetime delinquency and crime, and interactions with service and justice systems. Interviews were analyzed using ATLAS/ti software and a grounded-theory approach. The emergent themes revealed a myriad of consequences experienced by the children, including child witnessing of violence, emotional sequelae, bodily harm from abuse and neglect, sexual abuse, and birth defects from prenatal violence. Implications for research and practice are discussed.  相似文献
