To what extent do economic concerns drive anti‐migrant attitudes? Key theoretical arguments extract two central motives: increased labour market competition and the fiscal burden linked to the influx of migrants. This article provides new evidence regarding the impact of material self‐interest on attitudes towards immigrants. It reports the results of a survey experiment embedded in representative surveys in 15 European countries before and after the European refugee crisis in 2014. As anticipated by the fiscal burden argument, it is found that rich natives prefer highly skilled over low‐skilled migration more than low‐income respondents do. Moreover, the study shows that these tax concerns among the wealthy are stronger if fiscal exposure to migration is high. No support is found for the labour market competition argument predicting that natives will be most opposed to migrants with similar skills. The results suggest that highly skilled migrants are preferred over low‐skilled migrants irrespective of natives’ skill levels.  相似文献

Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability.  相似文献

Early alcohol use is associated with multiple negative outcomes later in life, including substance use disorders. Identification of factors related to this very early risk indicator can help inform early prevention efforts. This study prospectively examined the relationship between childhood adversities and early initiation of alcohol use (by age 14) among Puerto Rican youth, the Latino subgroup at highest risk for alcohol use disorders in adulthood. The data come from the Boricua Youth Study, a longitudinal study of Puerto Rican youth in two sites (South Bronx, New York, and the standard metropolitan area of San Juan, Puerto Rico). We focus on youth who were ages 10 and older at Wave 1 [M age at Wave 1 (SE)?=?11.64(0.05), N?=?1259, 48.85?% females]. Twelve childhood adversities were measured at Wave 1 and include 10 adverse childhood experiences commonly studied and two additional ones (exposure to violence and discrimination) that were deemed relevant for this study’s population. Early initiation of alcohol use was determined based on youth report at Waves 1 through 3 (each wave 1 year apart). Cox proportional hazards models showed that, when considered individually, adversities reflecting child maltreatment, parental maladjustment, and sociocultural stressors were related to early initiation of alcohol use. Significant gender interactions were identified for parental emotional problems and exposure to violence, with associations found among girls only. Adversities often co-occurred, and when they were considered jointly, physical and emotional abuse, parental antisocial personality, and exposure to violence had independent associations with early alcohol use, with a stronger influence of exposure to violence in girls compared to boys. The accumulation of adversities, regardless of the specific type of exposure, increased the risk for starting to drink at a young age in a linear way. The associations between childhood adversities and early alcohol use were generally consistent across sociocultural contexts, in spite of differences in the prevalence of exposure to adversity. Our findings highlight the importance of targeting multiple adversities and expanding the notion of adversity to capture the experiences of specific groups more adequately.  相似文献

Faced with pressing climatic changes, scientific and industrial interests are vying to develop crops that can survive drought, floods and shifting pest regimes. Increasingly, they look for solutions in an unlikely place: the gene pools of wild plants. Crop wild relatives (CWR) – species closely related to crops, including their ancestors – offer breeders the allure of retracing the domestication bottleneck, infusing genomes of modern crops with ‘lost’ genetic variety. Yet wild relatives also confront threats from climate change, urbanization and expansion of industrial agri-food. Thus, CWR, seen as both salvational and threatened, have become an international conservation and food-security priority. It is my contention that, in their common project to harness wild-relative potential, conservation and breeding science are co-evolving to extend seed commodity relations into new spheres. I examine enclosures along two fronts: first within ‘systematic CWR conservation’, where ‘in situ’ approaches, typically regarded as empowering and sustainable alternatives to ‘ex situ’, instead may support a complementary system of value extraction; second, in breeding and biotechnology research, which produces new value for CWR while profoundly shaping upstream conservation priorities. An important finding is that although today’s ‘ex situ-centric’ complementarity favors dispossession, an ‘in situ-centric’ approach could foster democratic renewal of biocultural diversity.  相似文献

This article applies Saidiya Hartman’s framework of performing blackness to South African performance artist Athi-Patra Ruga’s performance series, The Future White Women of Azania, to consider the ways in which the performances index the convoluted imbrications of colonialism, specifically Apartheid policy in South Africa, and postcolonialism, specifically the anti-Apartheid struggle(s) and the current political and economic structure of South African democracy. It argues that Ruga’s performance makes evident political and economic systems that tout black and queer liberation while perpetuating black queer death. Ruga’s work also relocates Hartman’s framework to a transnational, postcolonial context, expanding the notion of performing blackness (and the entangled processes of domination and subordination that it maps) beyond the trans-Atlantic paradigm, suggesting that performing blackness could be used to understand the correlation between broader spatial and temporal phenomena that shape blackness. Finally, situating The Future White Women of Azania as not only a performance of blackness, but of queerness as well, postulates that layering sexuality onto Hartman’s model reveals that the dynamics articulated under performing blackness are evident between oppressors and oppressed and between members of each of these groups as Hartman notes, but also between the contingent axes of subjectivity within an individual’s experience.  相似文献

In this Special Section, this article reviews South Korean views on Japan's ‘peace’ Constitution and the Abe government's attempts at constitutional reform. It identifies three different understandings among South Korean academics on why Japan is escalating attempts to revise the Constitution under the Abe government. An in-depth analysis demonstrates that all three perspectives pay specific attention to Japan's constitutional reform in relation to security policy changes. However, they differ in assessing the impact of Japan's constitutional reform on South Korea as well as how South Korea should deal with such a change. A minority opinion considers Japan's ‘remilitarisation’ through constitutional revision as conducive to South Korean security interests by increasing deterrence against North Korea, whereas the dominant opinion is that any attempt to revise the Constitution could be in and of itself a potential threat to South Korea's security due to a lack of trust attributed to unresolved historical conflicts between Korea and Japan. However, all three approaches pay hardly any attention to the positive role of Japan's peace Constitution while Japan's peace Constitution might provide a regional peace model in Northeast Asia.  相似文献

Policymakers have actively pursued urban renewal and dispersal programs to deconcentrate poverty in urban neighborhoods. Relocation strategies lead to new housing opportunities and may encourage employment opportunities for relocated residents if resourceful contacts and job information become more easily available after the move. This study provides an innovative evaluation of the early impacts of involuntary relocation programs in the Netherlands on the housing careers, earnings and employment rates of forced relocatees. It establishes a quasi-experimental design by employing unique longitudinal individual-level population registry data from Statistics Netherlands: forced relocatees are tracked and matched to a control group consisting of similar residents that were not forced to move. A difference-in-difference design shows that forced relocatees are living in less deprived neighborhoods after the move. However, we find no conclusive evidence that this upgrade in housing leads to more socioeconomic opportunities for the forced relocatees.  相似文献

Fair Market Rents (FMRs), calculated for an entire metropolitan region, are used to establish payment standards for the Housing Choice Voucher (HCV) program. In response to recent criticism that FMRs do not represent rent disparity and restrict households from moving to high-opportunity areas, a new rule introducing Small Area Fair Market Rents (SAFMRs) has been issued. SAFMRs are based on ZIP codes to reflect local market rents and increase the number of payment standards used to administer the HCV program. The purpose of this research is to determine whether the number of payment standards can be reduced by consolidating ZIP codes, while adhering to the primary objectives of the SAFMR rule. The ZIP code grouping process conducted offers one method for reducing the number of payment standards needed to implement the new rule; however, the rent analysis reveals the over- and underestimation of SAFMRs for some ZIP codes.  相似文献
