Advocates of the “borderless world” thesis suggest that migrant workers can benefit from employment opportunities available everywhere, with workers simply migrating towards these opportunities. However, as global inequalities widen and potential global mobilities develop, states are “managing” migration. Individual migrant “agency”, its structuration, and the subsequent experiences of migrants and employers, can restrict such mobility. Consequently, there is a need to describe and problematize the new strategies. This article considers these issues with reference to the emerging impact of the migrant cap on non‐European Economic Area (EEA) migrants to the United Kingdom (UK). It explores the links between immigration and employment rights and the implications for migrant mobility. Policies of “managed migration” frequently do not take into account issues of geography and intra and inter regional competition for migrants by employers operating in sectors with skill shortages, or differential migrant “agency” in the form of their skills and attributes. This may impinge on the effectiveness of such approaches and on economic prosperity at a national, regional and local scale. 相似文献

Taking out student loans to assist with the costs of postsecondary schooling in the US has become the norm in recent decades. The debt burden young adults acquire during the higher education process, however, is increasingly stratified with black young adults holding greater debt burden than whites. Using data from the NLSY 1997 cohort, we examine racial differences in student loan debt acquisition and parental net wealth as a predictor contributing to this growing divide. We have four main results. First, confirming prior research, black young adults have substantially more debt than their white counterparts. Second, we find that this difference is partially explained by differences in wealth, family background, postsecondary educational differences, and family contributions to college. Third, young adults’ net worth explain a portion of the black–white disparity in debt, suggesting that both differences in accumulation of debt and ability to repay debt in young adulthood explain racial disparities in debt. Fourth, the black–white disparity in debt is greatest at the highest levels of parents’ net worth. Our findings show that while social and economic experiences can help explain racial disparities in debt, the situation is more precarious for black youth, who are not protected by their parents’ wealth. This suggests that the increasing costs of higher education and corresponding rise in student loan debt are creating a new form of stratification for recent cohorts of young adults, and that student loan debt may be a new mechanism by which racial economic disparities are inherited across generations. 相似文献

ABSTRACTPractices of border control increasingly rely on digital biometrics in order to sort and filter cross-border movements. But while its effects are well examined in migration and border studies, less is known about the intricate ways in which biometric bordering is politically negotiated and socio-technically put into practice. Therefore, in this paper, I trace the contested emergence of one particular scheme of biometric border control currently in the making: the EU’s Smart Borders Package. Proposed by the European Commission in 2013, it aims at digitally registering all third-country nationals’ entries to and exits from the Schengen area, while simultaneously accelerating the border crossing of certain travellers. I argue that, unlike other forms of biometric bordering, the Smart Borders Package problematises border control primarily on the level of its temporalities and constitutes the speed of border crossings, the timing of control as well as third-country nationals’ duration of stay as distinct objects of governing. Meanwhile, the project’s political negotiations have sparked techno-political controversies that repeatedly brought it to the brink of failure. Yet, these controversies have significantly enhanced the intelligibility and practicability of biometric bordering, contributing to the emergence of what I call the self-service border. 相似文献

Harsanyi's impartial observer must consider two types of lotteries: imaginary identity lotteries (“accidents of birth”) that she faces as herself and the real outcome lotteries (“life chances”) to be faced by the individuals she imagines becoming. If we maintain a distinction between identity and outcome lotteries, then Harsanyi‐like axioms yield generalized utilitarianism, and allow us to accommodate concerns about different individuals' risk attitudes and concerns about fairness. Requiring an impartial observer to be indifferent as to which individual should face similar risks restricts her social welfare function, but still allows her to accommodate fairness. Requiring an impartial observer to be indifferent between identity and outcome lotteries, however, forces her to ignore both fairness and different risk attitudes, and yields a new axiomatization of Harsanyi's utilitarianism. 相似文献

The aim of a phase II clinical trial is to decide whether or not to develop an experimental therapy further through phase III clinical evaluation. In this paper, we present a Bayesian approach to the phase II trial, although we assume that subsequent phase III clinical trials will have standard frequentist analyses. The decision whether to conduct the phase III trial is based on the posterior predictive probability of a significant result being obtained. This fusion of Bayesian and frequentist techniques accepts the current paradigm for expressing objective evidence of therapeutic value, while optimizing the form of the phase II investigation that leads to it. By using prior information, we can assess whether a phase II study is needed at all, and how much or what sort of evidence is required. The proposed approach is illustrated by the design of a phase II clinical trial of a multi‐drug resistance modulator used in combination with standard chemotherapy in the treatment of metastatic breast cancer.

Researchers have begun assessing differences in well-being among parents versus non-parents using a cross-national comparative approach. Given the availability of multiple major datasets, a systematic methodological study isolating the effects of data choice would be helpful. To accomplish this objective, we draw upon two major datasets (European Social Survey and International Social Survey Programme) and we devise and implement a uniquely controlled method on five fronts by holding time, outcome measurement, parenthood operationalization, geographic sampling, and set of covariates constant. Our design features four distinct observations for each of 11 European countries (two from the 2006 and 2008 ESS, two from the 2007 and 2008 ISSP; 44 cross sections, N = 57,539). Employing both fixed- and random-effects approaches, we demonstrate that choice of major dataset (ISSP or ESS) and choice between contemporaneous cross-sections both contribute strikingly to the estimates of parenthood on happiness. In fact, effect variances at the cross-sectional, dataset and country levels are all significant and are not statistically different. We conclude by discussing several limitations of our analyses and implications for parenthood researchers. 相似文献

This article attends to the collaborative project of Gilles Deleuze and Felix Guattari, and specifically to their concept of “probe‐head” as mapped out in A Thousand Plateaus. Probe‐head names the rupturing of, and production of alternative modes of organisation to, the mixed semiotic of faciality that determines much of our lived life, in fact that constitutes us as “human”. In exploring this alternative “production of subjectivity” the essay attends also to Deleuze and Guattari’s notion of “several regimes of signs”, and to the idea of an experimental “pragmatics” of living. The essay goes on to map out what might be called two operating terrains of probe‐heads, in fact two different “times” of the contemporary – the past and the future – and looks at how these might be deployed against the impasses of the present. As far as the latter goes the essay looks at case studies of myth/modern paganism and contemporary art production. 相似文献

This study examined associations between interparental conflict and adolescents' romantic relationship conflict. High school seniors ( N =183) who lived with married parents completed questionnaires about their parents' marriage and their own romantic relationships. A subset of 88 adolescents was also observed interacting with their romantic partners. Adolescents' perceptions and appraisals of interparental conflict were related to the amount of conflict in romantic relationship and adolescents' conflict styles. Adolescents' appraisals of interparental conflict (i.e., self-blame, perceived threat) moderated many of the associations between interparental conflict and conflict behavior with romantic partners. The patterns of moderated effects differed by gender. These findings suggest that the meanings boys and girls ascribe to interparental conflict are important for understanding how family experiences contribute to the development of romantic relationships. 相似文献
