ABSTRACTScholars increasingly view urban areas as fragmented spaces where migrants are policed in ways that promote differential access to mobility, but the glocal meanings of race are often undertheorized. This paper explores the mobility experiences of Ethiopian migrants in four cities: Washington, DC, Tel Aviv, Rome, and Melbourne. Using a textual analysis of newspaper coverage in each city, the analysis finds that media and police often act as agents who racialize Ethiopian migrants relative to native minorities and other migrants. The paper concludes that the experiences Ethiopian immigrants faced in urban areas were informed by glocal meanings of race (blackness); they were shaped in relation to not only other migrants and native minorities, but also a globalized discourse on immigration. 相似文献

We study the problems of non-preemptively scheduling and packing malleable and parallel tasks with precedence constraints to minimize the makespan. In the scheduling variant, we allow the free choice of processors; in packing, each task must be assigned to a contiguous subset. Malleable tasks can be processed on different numbers of processors with varying processing times, while parallel tasks require a fixed number of processors. For precedence constraints of bounded width, we resolve the complexity status of the problem with any number of processors and any width bound. We present an FPTAS based on Dilworth’s decomposition theorem for the NP-hard problem variants, and exact efficient algorithms for all remaining special cases. For our positive results, we do not require the otherwise common monotonous penalty assumption on the processing times of malleable tasks, whereas our hardness results hold even when assuming this restriction. We complement our results by showing that these problems are all strongly NP-hard under precedence constraints which form a tree. 相似文献

School closures across Australia in response to COVID-19 have persisted since 2020, with rising mental health problems in children and adolescents, alongside rising negative family health and socioeconomic outcomes. Further, some children and young people who were already experiencing disadvantage pre-pandemic may be at heightened risk of poorer educational outcomes. Therefore, the aim of this study was to conduct a systematic review of the literature to identify the factors for poorer educational outcomes that may be exacerbated by COVID-19 amongst disadvantaged school students. Key development stages of disadvantage were identified: young children who started school behind, older students already at risk of disengagement from school and children and young people who have had contact with the child protection system. Five databases were systematically searched, across two search periods. A total of 69 Australian, peer-reviewed articles, published in 2005–2021, examining risk factors for poor educational outcomes for children attending school met the inclusion criteria and were included in final analyses. Our findings provide evidence of key risk factors that make these populations susceptible to worsening outcomes resulting from the COVID-19 pandemic, and of the critical importance of ongoing research to guide policy and practice support for these at-risk groups. 相似文献

Sociological and cultural research on market participation has been preoccupied with creative markets and traditional labor markets, overlooking alternate types of markets, particularly those of human goods which have proliferated in Asia. This article analyzes South Korea's cosmetic surgery market to examine how and why consumers participate in markets of human goods on the microlevel vis-à-vis macrolevel social structures in an advanced capitalist economy. This article theorizes two cognitive frames (normative conformity and competitive edge) that rationalize and motivate surgical modifications as an alternative vehicle for financial and marital stability in response to macrolevel economic challenges from the nation's developmental trajectory and cultural anxieties from its Confucian traditions about marriage. 相似文献

Organizations have been an important setting in which social capital exchanges (SCEs) occur, but little work has been done to distinguish two predominant species of organizations in the social network literature: voluntary associations and formal work organizations. Addressing this lacuna, this article comparatively examines how the two organizational species differ in (1) how two prominent types of SCEs operate (restricted and generalized exchange), as well as (2) the analytical approaches and methodological tools for studying SCEs (boundary-specification, sampling, network designs, tie-recording methods) and their adherent implications for network structure (networking conditions and homophily). This article concludes by identifying methodological and theoretical challenges for studying SCEs in organizations (conceptualizing organizations as units, underappreciating meaning-making and methodological triangulation, and examining contagion in organizational networks in an age of digitalization) and developing recommendations for overcoming them. 相似文献

Early studies and theory suggest sexual minorities are drawn towards the relative independence of self-employment to avoid discrimination in paid employment. However, recent evidence is mixed, suggesting that a higher propensity for self-employment (relative to heterosexual people) is found only among lesbian women relative to heterosexual women. This study overcomes the data limitations of prior research by using data pooled from 2007–2017 cycles of the Canadian Community Health Survey (CCHS) and multivariate logistic regression to provide new evidence on LGB self-employment. The results show that self-employment is particularly high for bisexual people, especially bisexual women—but not for gay men or lesbian women. Overall, this study examines the enduring but nuanced relationship between self-employment and sexual orientation and discusses countervailing factors related to socio-economic resources, gender, and family structure. 相似文献

Although the number of students attending university has been steadily increasing over the past 20 years, discrepancies remain across racialized student groups. Students who immigrate to Canada also face a number of barriers to university participation. However, few studies investigate variations in university participation across racialized immigrant student groups. We draw on an intersectional approach to analyze student data from the Toronto District School Board. We employ multilevel logistic regression to examine if there are interactive effects of being both racialized and having an immigrant status on confirming a university enrollment. Looking at self-identified race and immigrant status of students in combination reveals that there are important differences in the likelihood of confirming and offer of university admission between several self-identified racial categories, depending on if they were foreign-born. 相似文献
