This paper tests the assumption that a stronger presence of migrant teachers in preschool can help to reduce ethnic disadvantages and contribute to more equality of opportunity. To this end, migrant children who are taught by teachers with a migration background are compared to those who are confronted with only autochthonous teachers in their day-care centre. The outcome variables include competencies in German language, mathematics, science, as well as social competencies of the children. In addition, the study investigates the contact frequency of migrant parents with the day care centre to test whether contact is enhanced in centres which employ migrant teachers. Contrary to expectations, propensity score matching analyses based on the Kindergarten cohort of the German National Educational Panel Study (NEPS) show that migrant children do not achieve higher competencies when being taught by migrant teachers. Similarly, contact to migrant parents is not improved. More teachers with a migration background will hardly reduce ethnic disadvantages in educational outcomes.  相似文献

In recent years, INGO legitimacy has been subject to growing scrutiny from analysts and practitioners alike. Critics have highlighted a backlash against INGOs in the Global South, a growing mismatch between INGO capacities and contemporary global challenges, and diminishing support for norms such as democracy and human rights that underpin INGOs’ work. Although these problems have attracted significant attention within the academic literature, this article argues that existing explorations of INGO legitimacy have broadly conformed either to a top-down approach focused on global norms and institutions or a bottom-up approach focused on the local dynamics surrounding states and populations in the Global South. We suggest that this divide is unhelpful for understanding the current predicament and propose a new approach, which pays closer attention to the interaction between bottom-up and top-down dimensions, and to historical context. This new approach can provide important insights into current debates about the future roles and internal structures of INGOs.  相似文献

The Disability Discrimination Act was 20 years old in 2015 and received much attention, being presented as a cause for celebration. In what follows I suggest that this is far from being an accurate assessment of its impact and go on to suggest that it was not achieved as a result of a broad consensus but rather the product and ultimate betrayal of the hopes and dreams of disabled people ourselves. As such, my version of this history has important lessons for disabled people ourselves.  相似文献

Specification tests for conditional heteroskedasticity that are derived under the assumption that the density of the innovation is Gaussian may not be powerful in light of the recent empirical results that the density is not Gaussian. We obtain specification tests for conditional heteroskedasticity under the assumption that the innovation density is a member of a general family of densities. Our test statistics maximize asymptotic local power and weighted average power criteria for the general family of densities. We establish both first-order and second-order theory for our procedures. Simulations indicate that asymptotic power gains are achievable in finite samples.  相似文献

A nation’s population is redistributed through migration flows and counterflows between its constituent subnational areas, resulting in a geographical pattern of net migration gains or losses which may change from one time period to another. Migration effectiveness is the indicator commonly used to measure net migration as a proportion of gross migration turnover for any territorial unit. This paper explores the effect of net migration in two different countries, Australia and the United Kingdom, using measures of migration effectiveness computed from period-age migration data sets for a system of city regions assembled for four consecutive five-year periods in each country. While the evidence suggests that the overall effectiveness of net migration has declined over the 20-year period in both countries, marked similarities and contrasts are apparent in the spatial patterning of migration that together provide useful analytical insights into the changing space economies of the two countries.  相似文献

The effect of retirement on life satisfaction is a research topic that received a lot of attention, yet provided heterogeneous results. The current study suggests a remedy for this situation by taking two predictors of diversity (i.e. education and last labor market status) into account. We assumed that changes in social status and changes in resources influence retirement adjustment. The social status change affects retirees in the short-term, whereas individuals’ resources indicated by education predict long-term adjustment. To disentangle these processes, we contrasted exits from full-time employment and transitions from unemployment. We used data from the German Socio-Economic Panel to estimate a multi-group, multi-episodes dual change score model. The development of life satisfaction is lastingly interrupted by retirement. A short-term increase in life satisfaction was found for both transition groups but was more pronounced for those being previously unemployed. Life satisfaction develops in the long-term education-specific: retirees who have more education show almost constant life satisfaction whereas those retirees who have less education experience a decline. The results indicate that retirement entails a major change in the way people live. Adjustment to this can be characterized by two processes: A status change enfolds in the short-term. A building of new daily routines using individuals’ resources develops in the long-term. Both processes can be interpreted in terms of cumulative inequality: last labor market status differences decrease in the short-term but remain. Educational differences increase after retirement.  相似文献

The United States Census Bureau Library, acting on a study commissioned in 2002, has undertaken to improve electronic access for their patrons. The library provides e-journal and database access. The staff relies on usage statistics from these resources to sharpen the focus of the collection. Through an aggressive outreach program Census Bureau employees learn about these new products and services. Future plans include adding more e-journals, an open OPAC, and a new library building.  相似文献
