Since 1982, the collaborative editorial project of the Freedmen and Southern Society Project has published four volume of documentary material placing African Americans as slaves, soldiers, and newly free people, at the center of the process of slave emancipation in the US South. This review of the Project's fifth volume of records, Land and Labor, 1865, critically examines its contribution to our understanding of the emergence of free labor relations in the economy of the postbellum rural South. There, three forces collided in the efforts to remake labor relations after the Civil War ended slavery in the US: the efforts of slaveholders to control property and labor; the aspirations to ‘access to land and control of their own labor’ of former slaves; and the desire of Northerners to impose their own notions of ‘free labor’ as a set of contractual relations on both. Land and Labor, 1865, demonstrates how former slaves and their actions can be placed at the center of the evolution of Reconstruction policy.  相似文献

Both domestic violence and trafficking in humans pose serious problems worldwide. However, there are differences in the ways in which battered immigrant women and trafficked immigrant women are responded to by governmental agencies in Greece and in the USA. Trafficking in humans has been securitized, that is, framed as an issue linked to international security risk. As such, countries that do not take legal action to stop human trafficking could face US sanctions such as loss of United States military and economic assistance. Under significant international pressure, Greece, since 2002, passed a law that criminalized trafficking in humans and took necessary steps for providing protection and assistance to trafficked victims. Nevertheless, domestic violence and battered women remain silent in Greek society, and the availability of services to victims of domestic violence has eroded. We argue that, due to different issue framing of victims of trafficking and battered women, the connection of trafficking in humans to national security fosters different legal protection outcomes. The comparison of battered immigrant women and trafficked victims between Greece and the USA reveals significant differences in protection of battered immigrant women in the Organization for Economic Cooperation and Development (OECD) area. This article elucidates why there are public policy differences within OECD states that all grant a priority to prevention of human trafficking.  相似文献

Sex estimation is the first step for biological profile reconstruction of an unknown skeleton (archaeological or contemporary) and consequently for positive identification of skeletal remains recovered from forensic settings. Several tools have been developed using different osseous structures. With the intention to provide an objective method comparison, we reported the analysis of three different methods (visual, metric and geometric morphometrics) for sex assessment of the greater sciatic notch. One hundred and thirty pelvic bones (45.4% females and 54.6% males) from the National Autonomous University of Mexico Skeletal Collection pertaining to the contemporary Mexican population were analyzed. We used the ROC-analysis to test between desired false positive thresholds (1-specificity) and expected true positive rates (sensitivity) in order to predict the best approach to sex assessment. The comparison of the area under the ROC-curves shows significant differences among visual and metric methods. At the same time, the analysis suggested that higher morphological variation among the sexes is independent of the methodological approach. The results indicate that the metric (angle), with a high percent of indeterminate cases (34.6%), and visual, with 26.2% of the cases allocated as intermediate cases, were poorly accurate; we cannot recommend these techniques for sexing an unknown specimen. On the other hand, the geometric morphometrics approach improves sex estimation in 82.3% of correctly classified individuals with more than 95% of posterior probability. In addition to the method comparison, the major sexual variation of the greater sciatic notch was determined to be located on its posterior border.  相似文献

This study examines the prospects for new European Union (EU) member countries in pursuing their foreign policy objectives in relations with China. Both the Czech Republic and Slovakia cherished an idea of making China an alternative economic partner. However, after 1989, China perceived these states as minor, almost unimportant partners, regardless of their efforts. Their profile was raised by EU accession but there was little change in their strength in terms of bilateral relations with China. The article investigates the failures and partial successes of the Czech and Slovak relationships with China, comparing their different approaches to the balance between focusing on political and human rights issues and the pursuit of economic and business interests.  相似文献

Depressive symptoms in Latino youth have been related to both culturally-universal and culturally-based stressors. However, few studies have examined the unique contributions of culturally-based stressors above and beyond other types of stressors. Moreover, no past studies with Latinos have examined the role of culturally-based stressors within a hopelessness model of depressive symptoms, a cognitive model with the strongest empirical support in adolescence. The current study examined these issues in a sample of 171 Latino adolescents (7th-10th grades; mean age?=?14; 46?% male). The Latino adolescents were primarily Mexican-American (78?%) and born in the United States (60?%). Students completed measures during a school period on their experiences of parent-child conflict, economic stress, discrimination from peers, and acculturative stress as well as depressive symptoms and attributional style. The results indicated that culturally-based stressors (e.g., acculturative stress and discrimination) predicted greater depressive symptoms even when controlling for culturally-universal stressors (e.g., parent-child conflict, economic stress). Moreover, a negative attributional style moderated the relationship between culturally-universal stressors and depressive symptoms, but this was not the case for culturally-based stressors. Culturally-based stressors play an important role in depressive symptoms among Latino youth. These stressors predicted greater symptomatology even when controlling for other types of stressors and a negative attributional style. These findings suggest that there may be other cognitive risk factors associated with culturally-based stressors.  相似文献

The literature consistently shows an association between pubertal maturation and internalizing problems in girls. The association for boys is less clear. The present study examines genetic and environmental influences on the association between pubertal maturation and internalizing problems for boys and girls in two primarily Caucasian adolescent twin/sibling studies: The Swedish Twin study of CHild and Adolescent Development (706 same-sex twin pairs aged 13-14, M = 13.7 years, 50 % female), and the Nonshared Environment in Adolescent Development sample (US-based, 687 same-sex twin/sibling pairs aged 10-18, M = 13.6 years, 47 % female). For girls, more advanced pubertal maturation was associated modestly with more internalizing problems, and that association was entirely explained by shared environmental influences. For boys, the association between pubertal maturation and internalizing problems was weak and inconsistent. Results for girls were remarkably consistent across samples. Findings suggest that nongenetic mechanisms mediate the association between pubertal maturation and internalizing problems. Findings have implications for intervention such that environmental influences shared by twins/siblings may provide the best targets for intervention strategies designed to minimize the potential negative effects of pubertal maturation on internalizing symptoms in girls.  相似文献
