As the boundaries of forensic DNA profiling continue to expand, less obvious sources of biological evidence are being collected at crime scenes for DNA profiling. One example is the recovery of biological evidence from common drink containers, such as bottles and cans, which have been found at crime scenes. There are many variables that may have an impact on recovering a DNA profile from such exhibits. In this research, the effects of person to person variation, time, type of drink (including alcoholic and non-alcoholic beverages), and type of drink container, were assessed for their impact on the major analytical outcomes of the DNA process. The results show that the alpha-amylase activity varies from individual to individual and is reduced in the presence of some alcoholic drinks. A reasonable DNA yield was obtained from all samples, however, the concentrations exhibited significant person to person variation. The type of drink container influenced the DNA yield with cans giving a higher yield than bottles of the same drink type. To a reduced extent the presence or absence of alcohol affected the overall DNA yield and when partial or failed DNA profiles were produced they were more likely to be associated with alcoholic drinks than non-alcoholic drinks. 相似文献

Since the US identified North Korea as part of the “axis of evil,” the forecast for North‐South Korean relations has worsened. However, this article suggests that contrary to popular opinion, the advent of the six‐party talks may prove surprisingly conducive to the improvement of inter‐Korean relations. Three tactical moves seem currently open to North Korea: threatening the use of force in an effort to stall international pressure; attempting to mend diplomatic relations with the US; or the initiation of closer ties with Seoul, with the good offices provided by Beijing. The last option may prove to be the best from a North Korean point of view and may be the first step towards achieving the longed‐for Korean reunification. 相似文献

This prospective study used 3 years of longitudinal data to explore relationships among intimate partner violence (IPV), perceived emotional and material social support, employment stability, and job turnover among current and former female welfare recipients in the immediate post-welfare reform era. Higher levels of current IPV and lower levels of current social support predicted less stable future employment; however, current employment stability did not predict either future IPV or future social support. Current social support did not predict future IPV, and perceived social support did not mediate the relationship between IPV and employment stability during a 3-year period. 相似文献

Development and Assessment of Postcranial Sex Estimation Methods for a Guatemalan Population 下载免费PDF全文
This study tests whether postcranial sex estimation methods generated from Hispanic, and mainly Mexican samples, can be successfully applied to other increasingly common migrant populations from Central America. We use a sample of postcranial data from a modern (1980s) Guatemalan Maya sample (n = 219). Results indicate a decrease in classification accuracies for previously established univariate methods when applied to the Guatemalan study sample, specifically for males whose accuracies ranged from 30 to 84%. This bias toward inaccuracies for Guatemalan males is associated with the smaller skeletal sizes for the Guatemalan sample as compared to the samples used in the tested sex estimation methods. In contrast, the tested multivariate discriminant function classification yielded less sex bias and improved classification accuracies ranging from 82 to 89%. Our results highlight which of the tested univariate and multivariate methods reach acceptable levels for accuracy for sex estimation of cases where the region of origin may include Guatemala. 相似文献

In these two fine contributions to the relatively small body of empirically‐grounded theoretical accounts of law, Fred Schauer and Richard McAdams focus on the two key elements of any legal system: the coordination of conduct that individuals have an incentive to engage in if they believe others will also, and the coercive force that is needed to deter conduct when coordination incentives are absent or insufficient. Both contributions deepen our understanding of the dynamics of coordination and coercion. But both also focus primarily on the concept of law as a set of rules generated and enforced exclusively by government. In this comment, drawing on recent work with Barry Weingast, I emphasize the importance of extending the scope of analysis to include settings in which governments are missing or weak and where legal order has not yet been achieved or stabilized—the challenge that faces many poor and developing countries around the world and the challenge that today's advanced legal regimes overcame historically. In our account, coordination and coercion are not substitute mechanisms, but are deeply linked: prior to the establishment of wealthy stable governments (and perhaps even in the presence of such governments), coercive penalties are delivered only if the decentralized application of punishment by ordinary individuals is successfully coordinated and incentivized. 相似文献
