Research on the effect of school choice on student performance has generally been based on small-scale experiments or comparisons of Catholic and public schools in the United States. Recent studies indicate, however, that the market competition stemming from school vouchers does not affect all private schools equally. This study makes use of individual-level register data on the performance of more than 30,000 students in Denmark, where private schools have been voucher-financed for more than 100 years, while public schools are governed and financed by the politico-administrative system. Using an instrumental variable model to exclude selection effects, the results show no significant average effect of private schooling on final examination scores. However, a multilevel model shows that private schools of high socio-economic status perform better than similar public schools, while private schools of low socio-economic status under-perform – even for individual students with high socio-economic status. This indicates that the institutional setting of a voucher system is not enough to raise educational performance in general, arguably because some parents choose schools on the basis of non-academic criteria. 相似文献
We apply formal, statistical measurement models to the Polity indicators, used widely in studies of international relations to measure democracy. In so doing, we make explicit the hitherto implicit assumptions underlying scales built using the Polity indicators. Modeling democracy as a latent variable allows us to assess the "noise" (measurement error) in the resulting measure. We show that this measurement error is considerable and has substantive consequences when using a measure of democracy as an independent variable in cross-national statistical analyses. Our analysis suggests that skepticism as to the precision of the Polity democracy scale is well founded and that many researchers have been overly sanguine about the properties of the Polity democracy scale in applied statistical work. 相似文献
Previous research has provided mixed results regarding the effect of anxiety on academic achievement. Building on this body
of research, the present longitudinal study pursued two goals. The first goal was to describe trajectories of anxiety during
elementary-school years. The second goal was to determine the predictive value of these trajectories on high school noncompletion
after controlling for personal (i.e., gender, classroom behaviors, and academic achievement) and familial (i.e., sociofamilial
adversity) characteristics. A community sample of 1,817 children (887 boys, 930 girls) participated in this study. Results
showed that anxiety tended to fluctuate from kindergarten to Grade 6 for different groups of children. Furthermore, the result
of a logistic regression analysis indicated that group membership for anxiety predicted high school noncompletion by age 20.
As a whole, these findings suggest that considering heterogeneous developmental patterns of anxiety during elementary-school
years appears quite useful for predicting an important outcome such as high school noncompletion.
ABSTRACTBased on interviews with 21 immigrants in Norway, including both naturalized citizens and ‘denizens’, this article addresses immigrant meanings of citizenship and naturalization. The findings show that the interviewees attributed three meanings to citizenship. First, Norwegian citizenship served as a powerful means of spatial mobility, thereby facilitating transnational connections. Second, citizenship signified a legal stability that may guard precarious immigrants against ‘liminal legality’, i.e. enduring legal uncertainty. Third, citizenship was conceptualized as a formal recognition of equality and belonging, although ‘race’ and ethnicity persisted as salient markers of inequality and alienage. The article contributes empirically to the growing literature on the experiencing side of citizenship and naturalization by delineating what citizenship means to different groups, and to whom it matters the most. Theoretically, it contributes by demonstrating that citizenship acquisition may not only be strategic, but also rooted in needs of symbolic sanctioning of equality and belonging, particularly important to individuals debarred from naturalization. 相似文献
“Access and allocation” is one of the five analytical problems identified as key for analysing earth system governance in the first Earth System Governance Science and Implementation Plan officially published in 2009. Ten years later and with a new Science and Implementation Plan in place, it is time to take stock. Therefore, this paper addresses the question: What does a decadal review of the Earth System Governance literature tell us about how to conceptualize and define access and allocation, what ethical norms and epistemologies underlie access and allocation research, and what does Earth System Governance scholarship reveal about the interplay between access and allocation and other norms? We find that: (a) there is a relatively small body of the Earth System Governance literature on access and allocation, albeit growing; (b) this literature is largely empirical and dispersed across a variety of topics; and (c) there is a diversity of ethical norms and principles emphasized in Earth System Governance scholarship, but the dynamics between different forms of access and related implications for allocation are relatively underexplored. In light of these findings and with a new Earth System Governance Science and Implementation Plan in place, this paper highlights key areas for further research and development.
This article reviews the Land Registration Act 2002, taking advantage of the deeper perspective afforded by the intervening decade, and absorbing subsequent developments – and, in the case of the Act's electronic conveyancing project, non‐developments – that have also come to contribute to the picture. It suggests especially that while the Act's central idea of conclusive, indeed ‘constitutive’, registration can be beneficial, its deployment here has been problematic. In particular, the lapse of electronic conveyancing, and the possibility (resisted by the courts) that conclusive registration can be procured by fraudsters, have diminished the control that parties have over dispositions of their own title, to the detriment of their autonomy; and over‐preoccupation with the central idea has resulted in a failure to think carefully enough about problems to which it was never going to be the answer. 相似文献
I examine the ways in which the global financial crisis that began in 2007, and whose effects arguably condition policymaking to the present day, affected the ongoing global power transition as manifested by the unilateral decisions undertaken by official agencies comprising national regulatory states. The theory of that power transition articulated in the overview paper of this Special Issue is reinterpreted to take into account the circumstances of that crisis. Empirical evidence on the propensity to discriminate against foreign commercial interests by the BRICS, Turkey, the European Union, and the United States during the years 2008 to 2017 at, and behind, the border is employed to identify a group of six potential rule-shapers and two possible sham rule-takers. 相似文献

A 59-year-old man was found dead in his living room. His body was covered with blood, but the only injury found was a 31-mm-long, transverse incision on the radial surface of the left forearm. Autopsy revealed that the injured vessel was an enlarged cephalic vein from a radiocephalic arteriovenous fistula (RC-AVF) that had been created 23 years before for hemodialysis. Cephalic vein injury is usually not fatal, but circumstantial evidence, autopsy, and histological findings suggested that hemorrhagic shock and death occurred within a short time after the self-inflicted incised wound. This may be explained by the blood flow rate in the RC-AVF, which can reach 12 ml/s; this is 25 times higher than the normal cephalic vein blood flow. 相似文献
