This research explored the feasibility of using the degradation rate of deoxyribonucleic acid (DNA) in human rib bone to determine the time interval since death. Postmortem human rib samples were surface sterilized and incubated under sterile conditions in either high or low humidity conditions at room temperature for a period of weeks. At selected times, portions of the bone were cut away, and the DNA from these samples was extracted and subjected to strand separating gel electrophoresis. The DNAs in the gels were transferred to a nylon membrane, preserving their relative positions as in the gel, and probed with radioactive total genomic human DNA. Autoradiograms produced were scanned and digitized. When the samples were incubated under identical conditions, the degradation rate of DNA in samples from different individuals appeared very similar. The DNA degradation rate may vary with temperature and humidity more than it varies between individuals. 相似文献

The Effect of Paramilitary Protest Policing on Protestors' Trust in the Police: The Case of the “Occupy Israel” Movement 下载免费PDF全文
The use of paramilitary methods in civil policing tasks has become common in Western police agencies. Despite propositions that such methods should undermine the relationship between the police and the public, the effect of paramilitary policing on public trust in the police has not been empirically tested. In the present study, we examine this question in the context of protest policing, which has become a major concern for Western police agencies. Using a survey of 470 protesters who participated in “Occupy” protest events in Israel in 2012, we find that the perceived use of paramilitary methods has an independent and negative effect on trust, stronger than that of police effectiveness and the “neutrality” component of procedural justice. In‐depth interviews suggest that the significance of paramilitarism may be the result of a sense of alienation and criminalization it elicits among protesters who generally perceive themselves as law‐abiding citizens. 相似文献

Barbara Perry 《Contemporary Justice Review》2013,16(3):231-247
The contemporary phenomenon of ethnoviolence - otherwise known as hate crime - has its roots deeply embedded in the historical persecution of Native Americans by representatives of 'the state and private individuals alike. Genocidal policies and practices of the past have their present counterparts in anti-activist and anti-treaty violence, as well as in isolated acts of violence against individual Native Americans. This paper traces the threads that bind together the (d)evolution from ethnocide to ethnoviolence. 相似文献
