Sex determination from the talus of Koreans by discriminant function analysis

The aims of this study were to investigate the sex discriminating potential of the talus in Koreans and compare this with other analyses in different populations. Statistical analyses were performed using data from nine measurements acquired from 140 tali (70 men, 70 women). The talus of Koreans is dimorphic between sexes in all measurements (p < 0.01). Discriminant function equations were generated by univariate, multivariate, and stepwise methods with a range of accuracy from 67.1 to 87.1%. Stepwise equations of other populations did not discriminate the sex of the Korean sample as accurately as each equation's own accuracies. The variables with high accuracy in this study are useful for sex determination of Koreans on the basis of confirmation of population specificity.     

Forensic Analysis of mtDNA Haplotypes from Two Rural Communities in Haiti Reflects Their Population History

Abstract: Very little genetic data exist on Haitians, an estimated 1.2 million of whom, not including illegal immigrants, reside in the United States. The absence of genetic data on a population of this size reduces the discriminatory power of criminal and missing‐person DNA databases in the United States and Caribbean. We present a forensic population study that provides the first genetic data set for Haiti. This study uses hypervariable segment one (HVS‐1) mitochondrial DNA (mtDNA) nucleotide sequences from 291 subjects primarily from rural areas of northern and southern Haiti, where admixture would be minimal. Our results showed that the African maternal genetic component of Haitians had slightly higher West‐Central African admixture than African‐Americans and Dominicans, but considerably less than Afro‐Brazilians. These results lay the foundation for further forensic genetics studies in the Haitian population and serve as a model for forensic mtDNA identification of individuals in other isolated or rural communities.     

Mismeasuring Militias: Limitations of Advocacy Group Data and of State‐Level Studies of Paramilitary Groups

The errors associated with measuring the number of militia and patriot groups may cast doubt on conclusions drawn from prior studies of the spatial variation of these movements. Most studies of militias have been qualitative investigations of a single group, state, or region. A growing number of studies, however, have used quantitative techniques to assess the hypothesis that the number of militia groups by state covaries with structural and cultural forces. We outline a number of concerns with the validity of the counts, conducted by the Anti‐Defamation League and the Southern Poverty Law Center, used by these studies. We re‐estimate models from previous studies using the four alternative measures of these groups employed in prior studies. We find that many inferences drawn for identical theoretical models differ based upon the measure used. These discrepancies apply not simply to tangential control variables but to indicators of key theoretical constructs. In other words, the decision as to whether or not a particular theoretical framework receives empirical support often depends upon which measure of the dependent variable is used. This suggests that the inconsistent findings in prior research may be due to measurement error and makes it difficult to assess the validity of the conclusions drawn from these studies. It is important to be aware of these weaknesses since scholars studying political crimes and related phenomena often use information from similar sources, making this specific example relevant to a more general area of research.     

Social Construction： the Reconstruction of China＇s Interests Pattern in Two--way of Movement

在社会转型初期,自由市场逻辑主导下的社会变革激发了社会活力,释放出了巨大能量,但也因利益在社会成员中的不均衡分布而产生对经济发展公平性的质疑。伴随市场力量的不断强大,社会自我保护力不断增强,使得社会矛盾呈愈演愈烈之势。在世界社会治理机制由一元向多元转变的趋势下,中国也开启了社会治理机制的变革之路,其核心议题在于建构何种国家、市场与社会力量的分配格局。这对于深化中国社会转型进程,实现社会稳定有序,奠定社会管理的社会基础具有十分重要的意义。然而,如何进行社会建设,不能给出简单的、想当然的结论,而需要挖掘其背后的支配逻辑——双向运动,以此重塑国家、市场与社会三者之间的关系。     

新媒体在“太阳花学运”中的动员与支持作用

2014年3月18日,台湾部分反对两岸服务贸易协定的学生占领“立法院”,从而引发震动全岛的“太阳花学运”。学运组织者和参与者广泛利用新媒体传播工具来发布和散播反对意见,建构反服贸集体意识,建立学运动员网络,获取国际支持,筹措行动资源,支持各项行动的组织和管理,对于学运的发动和开展发挥了不可或缺的作用。本文首先阐述新媒体的传播特性及其社会应用,继而着重对新媒体在此次学运过程中的作用和影响进行分析,最后探讨新媒体本身所固有的局限性。

Genetic variation of different Peruvian populations using 23 autosomal STR markers

In the present study the genetic variation of different Peruvian populations was investigated. The samples for this study were obtained from 669 individuals distributed among 11 populations from Peru. All samples were analyzed using 23 autosomal STR markers. The Arlequin v3.5.2.2 software was used to determine the genetic distances (Fst) of the studied populations. Notable population substructure was detected between some populations.
