Abstract: At a recent bushland gravesite that contained a deceased male, a clod of soil displaying a striated toolmark was collected during the excavation of the grave. This clod was preserved, and the mark was cast using Mikrosil?. Shovels and a mattock, which had been discarded by the suspects, were subsequently found at another location. A toolmark comparison identified the hoe end of the mattock head as having produced the striated toolmark. 相似文献

This article forwards an anarchist analysis of the internet as inherently degrading of local community and the possibility of real democracy emerging. The authors suggest that rampant virtuality, based on the eradication of time and space as functional communicative restraints, acts to separate individuals from their face-to-face relationships and localities. They forward that local community is the only forum in which genuine democracy and an ecological society can hope to thrive. The article argues that in asking the question Where do you want to go today?, the internet attempts to create a virtual everywhere, a universalising logic that is to communication what the WTO and globalisation are to economics. Further, the piece forwards a view of technology and society in dialectic relationship with one another, suggesting that democratic tools and a democratic society rely on one another for their emergence. 相似文献

Based on data from the National Longitudinal Study of Adolescent Health (Add Health), the current study was the first to use measures of genetic polymorphisms (DRD2 and DRD4) to empirically examine the onset of crime. Net of the effects of race, age, gender, and low self-control, genetic polymorphisms explained variation in police contacts and arrest, but only among youths in low risk family environments. Moreover, youths with genetic risk factors experienced a later onset than youths without these risk factors. Borrowing from the behavioral and molecular genetics literatures, various interpretations of the findings are discussed as well as a call for increasingly interdisciplinary perspectives in criminology that encompass both sociological and biosocial frameworks. 相似文献

This paper examines the impacts of four abstinence-only education programs on adolescent sexual activity and risks of pregnancy and sexually transmitted diseases (STDs). Based on an experimental design, the impact analysis uses survey data collected in 2005 and early 2006 from more than 2,000 teens who had been randomly assigned to either a program group that was eligible to participate in one of the four programs or a control group that was not. The findings show no significant impact on teen sexual activity, no differences in rates of unprotected sex, and some impacts on knowledge of STDs and perceived effectiveness of condoms and birth control pills 相似文献
