We have analyzed variation of the mitochondrial DNA (mtDNA) hypervariable segments I and II (HVS-I and HVS-II) in 185 randomly chosen individuals from Korea to provide an expanded and reliable Korean database. Combined sequence comparison of HVS-I and HVS-II led to the identification of 167 different haplotypes characterized by 154 variable sites. One hundred and fifty-one of the haplotypes were individual-specific, 14 were found in two individuals and 2 were found in three individuals. A pairwise comparison of the 185 HVS-I/II sequences found an average of 10.11 +/- 4.63 differences between individuals. The random match probability and gene diversity for the combined hypervariable regions were estimated at 0.66% and 0.9988, respectively. Analyzing the expanded database including three previously reported data sets and the present data using haplogroup-based comparisons and comparison with closely related sequences allowed errors to be detected and eliminated, thus considerably improving data quality. Sample division comparisons based on PhiST genetic distance measures revealed no significant population differentiation in the distribution of mtDNA sequence variations between the present data set and a database in The Scientific Working Group on DNA Analysis Methods (SWGDAM), but did indicate differences from other sets of data. Based on the results of mtDNA profiles, almost all of the mtDNA types studied here could be classified into subsets of haplogroups common in east Asia, and show that the Koreans possess lineages from both the southern and the northern haplogroup complexes of east Asian populations. The new data, combined with other mtDNA sequences, demonstrate how useful comparison with closely related mtDNA sequences can be for improving database quality, as well as providing haplotype information for forensic and population genetic analyses in the Korean population.  相似文献

This longitudinal investigation examined main and interactive effects of coparent support and conflict on mother and child adjustment in 248 low-income, African American, single mother-headed families. The findings indicated that coparent conflict was a more robust predictor of mother and child maladjustment both cross-sectionally and longitudinally than was coparent support. Moreover, findings revealed that coparent conflict and support interacted to predict one parenting behavior, monitoring, both cross-sectionally and longitudinally. Coparent relationships characterized by high levels of support and low levels of conflict were associated with the highest levels of parental monitoring behavior, whereas coparent relationships characterized by low levels of support and high levels of conflict were associated with the lowest levels of monitoring. The findings highlight the importance of examining both positive and negative aspects of coparent relationships in this at-risk, but understudied, group.  相似文献

Formal equality and judicial neutrality can lead to substantive inequality for women and children, with social costs that extend beyond individuals and families and spill over into the larger social settings in which they are located. We consider the uniquely damaging effects of an “equality with a vengeance” (Chesney‐Lind & Pollack 1995) that resulted from “tough on crime” policies and the 1980s federal and state sentencing guidelines that led to the incarceration of more women and mothers. We argue that legal equality norms of the kind embedded in the enforcement of sentencing guidelines can mask and punish differences in gendered role expectations. Paradoxically, although fathers are incarcerated in much greater numbers than are mothers, the effect threshold is lower and the scale of effect on educational outcomes tends to be greater for maternal incarceration. We demonstrate both student‐ and school‐level effects of maternal incarceration: the damaging effects not only affect the children of imprisoned mothers but also spill over to children of nonincarcerated mothers in schools with elevated levels of maternal incarceration. We find a 15 percent reduction in college graduation rates in schools where as few as 10 percent of other students' mothers are incarcerated. The effects for imprisoned fathers are also notable, especially at the school level. Schools with higher father incarceration rates (25 percent) have college graduation rates as much as 50 percent lower than those of other schools. The effects of imprisoned mothers are particularly notable at the student level (i.e., with few children of imprisoned mothers graduating from college), while maternal imprisonment effects are found at both student and school levels across the three measured outcomes. We demonstrate these effects in a large, nationally representative longitudinal study of American children from the 1990s prison generation who were tracked into early adulthood.  相似文献

The current research produces regression models with sample sizes from 127 to 131 by initially employing a data set of 170 nations. The current study finds that ethnic heterogeneity and linguistic heterogeneity lead to higher homicide rates. However, religious heterogeneity has no impact on homicide rates. The present article also tests an interaction effect between population heterogeneity and income inequality. Unlike J. R. Blau and Blau (1982) and Avision and Loring (1986) proposition, the interaction term is not related to national homicide rates. The current study also discusses the theoretical implications of those findings.  相似文献

This article analyzes China’s coherence in international economic governance. When and how is China challenging the rules and norms of the prevailing international economic order? Has China adopted the current rules and norms across the board, or is it proceeding in an ad hoc or piecemeal manner? How can its (in) coherence be explained? To address these questions, I compare China’s profile vis-à-vis three dimensions of the global economic order: trade, investment, and development aid. I argue that in international trade and investment, China has neither sought nor brought about significant change. China is however, offering an alternative to the Western norms that until now have dominated the global development aid regime. China’s establishment of the Asian Infrastructure Investment Bank (AIIB) is notable in this regard, though it is still soon to determine if the Chinese-led development bank will break with existing norms. The article then considers possible theoretical explanations for the variation in China’s behavior across the three areas.  相似文献

There is a substantial literature that assesses the effects of tax‐exporting capacities on the tax structures and aggregate spending levels that state governments choose to implement, but no work exists that isolates the effects of state tax exporting on higher education spending. Using state‐level data for 1989, 1995, 2002, and 2007, we estimate for the median voter in each state the change in the marginal cost of higher education subsidization generated by tax exportation, and calculate the increased higher education spending that results. We consider three types of spending: state appropriations to public universities as well as need‐ and non‐need‐based aid awarded to in‐state students. We find that neither type of aid is responsive to the marginal cost, or tax price, faced by the median voter. However, the median voter's price elasticity of demand for state appropriations is statistically significant and negative. We find that the median voter's tax price is substantially reduced by the presence of prominent mining and tourism industries and by the federal deductibility offset available to firms. Thus, these tax‐exporting capacities exert upward pressure on voter demand for state appropriations to public universities.  相似文献

Professors Schauer and McAdams both seek a more or less sweepingly general theory of why we obey the law. But we should split, not lump. There are different reasons different actors in different social settings obey different laws–not only, but not least, out of regard for democratic decision making.  相似文献

The number of older adults involved in the criminal justice system is rising. Little is known about the state of health in older people who are arrested. This study compared characteristics and health care needs of older police custody detainees with their younger counterparts. The health characteristics of 57 police detainees aged over 50 were compared with 543 younger detainees. Older detainees had significantly higher rates of physical illness and risk of alcohol withdrawal. Although there were equivalent rates of mental disorder and drug taking compared with younger detainees, a higher proportion had presentations consistent with cognitive impairment due to possible dementing processes. Over 80% of older detainees were recommended to have a health assessment in police stations based on their presentation. Police detainees over 50 should be considered to have a health assessment as routine procedure. Further investigation should also be conducted into cognitive impairment in this group.  相似文献
