Time and crime: The link between teenager lifestyle and delinquency

This paper—based on data from a national survey of 14 and 15 year olds and their parents in England and Wales—examines the relationship between teenager lifestyles and activity patterns and self-report offending. The legal ways in which teenagers spend their time show consistent relationships with involvement in crime. Offenders and nonofienders differ markedly on both general and specific measures where they go, whom they are with, and what they do. Consistent with models of criminal behavior based on group processes, these differences in activity patterns also extend to a number of the major correlates of delinquency whose effects on crime are typically conceived in lifestyle terms. These results further indicate that the link between activity patterns and delinquency is different between males and females in the age group surveyed.     

Genetic variation in hemp and marijuana (Cannabis sativa L.) according to amplified fragment length polymorphisms

Cannabis sativa L. (Cannabaceae) is one of the earliest known cultivated plants and is important in the global economy today as a licit and an illicit crop. Molecular markers distinguishing licit and illicit cultivars have forensic utility, but no direct comparison of hemp and marijuana amplified fragment length polymorphism (AFLP) has been made to date. Genetic variation was surveyed in three populations of fiber hemp and a potent cultivar of marijuana using AFLP markers. Ten primer pairs yielded 1206 bands, of which 88% were polymorphic. Eighteen bands represented fixed differences between all fiber populations and the drug cultivar. These markers have practical utility for (1) establishing conspiracy in the cultivation and distribution of marijuana, (2) identifying geographic sources of seized drugs, and (3) discriminating illegal, potent marijuana cultivars from hemp where the cultivation of industrial hemp is permitted.     

The Motivation Behind Serial Sexual Homicide: Is It Sex,Power, and Control,or Anger?*

Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.     

Sex determination using nonmetric characteristics of the mandible in Koreans

The mandible is the largest and hardest facial bone and retains its shape better than other bones in the forensic and physical anthropologic field. The mandible can be used to distinguish among ethnic groups and between sexes. We examined the morphological characteristics of the mandibles of 102 Koreans of either sex. Of 13 nonmetric items of the mandible, the characteristic that best allowed the sexes to be distinguished was the contour of the lower border of the mandible: rocker-shaped mandibles predominated in males (68.1%), whereas most females (84.6%) exhibited a straight mandible. In addition, the mental region was shaped differently between the sexes: the shape of the chin in most males was generally bilobate or square (91.7%), whereas the chin in females was either square (45.5%) or pointed (54.5%). In this study, the positive predict values of male and female were 92.5% and 73.7%, respectively. Therefore, the nonmetric method used to analyze the mandible in this study can be used for sex discrimination.     

The Gender Gap among Teen Survey Respondents: Why are Boys more Likely to Report a Gun in the Home than Girls?

It is a reliable though unexplained feature of national surveys that include items on gun ownership that wives are less likely to report a gun in the home than husbands. In this article we extend the inquiry regarding this gender gap in reporting of household guns to include adolescent children (age 12–17 years). The California Health Interview Survey of 2001, the largest-ever state survey of its kind, includes over 4000 marital households in which both a parent and adolescent child were interviewed and asked whether there was a gun in the home. There is little “age gap” in reporting—California teens are almost as likely to say that there is a gun as are their parents—but there is a gender gap among both the teens and their parents. We also find a large gap in personal experience with guns—boys are three times as likely to report hunting or shooting with a family member than girls. This difference in experience fully accounts for the gender gap in reporting. The relevance of these findings for the interpretation of survey data is clear. Whether there is a gun reported in a home depends to a remarkable extent on which member of the household is asked the question. Hence, the method of selection of respondent(s) from within a household will affect estimates of the patterns and prevalence of gun ownership, and, potentially, the accuracy of case–control studies that use self-report information about guns in the home.

考古样品中Amelogenin同源基因的提取和检测

目的利用人类性染色体Amelogenin同源基因在X、Y染色体上序列长度的差异,选择设计引物,对考古样本进行古DNA性别信息研究。方法采用苯酚/氯仿-二氧化硅-超滤离心方法提取东岭墓葬群殉人骨骼、牙齿古DNA,PCR扩增,非变性聚丙烯酰胺凝胶电泳(PAGE)分离和检测古DNA扩增片段。结果8个墓葬16个样品中有7个样品出现阳性扩增检测,目标基因片段清楚,男性为二条带(X、Y),女性为一条带(X),牙齿样品检测成功率优于骨骼样品。结论改进的苯酚/氯仿—二氧化硅—超滤分离法是较好的古DNA提取方法,具有降低PCR抑制剂、消耗成本低和提取成功率高等特点。基于人类X、Y染色体Amelogenin同源基因的古DNA性别分析方法可成为分子考古重要的技术方法。     

论经济纠纷与经济犯罪交叉案件的处理原则——先刑后民原则的适用

“先刑后民”是司法实践中公安、司法机关处理经济纠纷与经济犯罪交叉案件的原则之一。目前,立法上关于经济纠纷与经济犯罪交叉案件处理标准的规定过于抽象,导致司法实践中公安、司法机关对“先刑后民”原则适用较为混乱。因此,应当从明确适用标准和健全移送机制两方面完善“先刑后民”原则在经济纠纷与经济犯罪交叉案件中的适用规则。
