Forensic genetic analysis of mitochondrial DNA hypervariable region I/II sequences: an expanded Korean population database

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.     

The impact of population heterogeneity and income inequality on homicide rates: a cross-national assessment

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.     

China’s Coherence in International Economic Governance

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.     

Democracy,Law, Compliance

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.     

Health characteristics of older police custody detainees in London,UK

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.     

Delinquent Behavior of Dutch Rural Adolescents

This article compares Dutch rural and non-rural adolescents’ delinquent behavior and examines two social correlates of rural delinquency: communal social control and traditional rural culture. The analyses are based on cross-sectional data, containing 3,797 participants aged 13–18 (48.7% females). The analyses show that rural adolescents are only slightly less likely to engage in delinquent behavior. Furthermore, while rural adolescents are exposed more often to communal social control, this does not substantially reduce the likelihood that they engage in delinquent behavior. Concerning rural culture, marked differences appeared between rural and non-rural adolescents. First, alcohol use and the frequency of visiting pubs were more related to rural adolescents’ engagement in delinquent behavior. Second, the gender gap in delinquency is larger among rural adolescents: whereas rural boys did not differ significantly from non-rural boys, rural girls were significantly less likely to engage in delinquent behavior than non-rural girls. However, the magnitude of the effects of most indicators was rather low. To better account for the variety of rural spaces and cultures, it is recommended that future research into antisocial and criminal behavior of rural adolescents should adopt alternative measurements of rurality, instead of using an indicator of population density only.     

After 30 Years,What Do We Know about What Jurors Know? A Meta-Analytic Review of Lay Knowledge Regarding Eyewitness Factors

Surveys typically characterize lay knowledge of eyewitness factors as low and highly variable. However, there are notable differences across methodologies, samples, and individual factors. To examine these differences systematically, we took a meta-analytic approach to reviewing the findings of 23 surveys assessing lay knowledge of eyewitness issues. Our analyses examined the beliefs of 4,669 respondents. Overall, respondents correctly agreed with survey items approximately two-thirds of the time. Results revealed significant differences in performance as a function of variable type, question format, and over time. We found few differences as a function of sample type, publication status, or jurisdiction. Although performance varied, a majority of lay respondents achieved “correct” consensus for as many as 11 of the 16 items included in this review.
