Since 1998, over 5500 people have died while attempting to cross the U.S.–Mexico border without authorization. These deaths have primarily occured in the Arizona desert. Despite the high volume of deaths, little experimental work has been conducted on Sonoran Desert taphonomy. In this study, pig carcasses were used as proxies for human remains and placed in different depositional contexts (i.e., direct sunlight and shade) that replicate typical sites of migrant death. Decomposition was documented through daily site visits, motion-sensitive cameras and GIS mapping, while skeletal preservation was investigated through the collection of the remains and subsequent faunal analysis. Our results suggest that vultures and domestic dogs are underappreciated members of the Sonoran scavenging guild and may disperse skeletal remains and migrant possessions over 25 m from the site of death. The impact of scavengers and the desert environment on the decomposition process has significant implications for estimating death rates and identifying human remains along the Arizona/Mexico border.  相似文献

The paper’s aim is to show to EU policy makers, academics, journalists and the general public what the available information tells us about crime levels, trends in crime and public opinion about crime among Member States. The paper centres on an analysis of current trends on crime levels and trends based on the data available both from victimisation surveys and police statistics. The victimisation survey source is the published data collected in the International Crime Victimisation Survey. A separate analysis based on the Eurobarometer was also carried out. Data on police statistics present two separate sources i.e. the Council of Europe Sourcebook and the crime data published annually by the UK Home Office. These two sources both add considerable value to the raw police statistics by their choice of data, their commentary and their technical explanations and definitions. The paper compares data on three crime types (robbery, domestic burglary and theft of a motor vehicle) across the 15 Member States of the European Union (as in 2003). These three types were selected in line with the priorities of the EU Commission and as types of crime that are a major concern for EU-citizens. The paper has been modified from a report produced by the European Crime prevention network for the EU Directorate of Justice and Home Affairs with the permission of the EU. The members of the network are listed in the appendix.  相似文献

The present research examined the extent to which feeling respected, versus feeling disrespected, influences people's willingness to contribute to the public good. Further, it was investigated why such a positive effect of respect should occur. The findings showed that respect indeed had a positive influence on contributions. In addition, it was shown that respect also positively influenced people's feelings of belongingness and that this feeling was found to mediate the effect of respect on contributions. These findings thus indicate that research on social decision-making, and more specifically social dilemmas, has to start devoting more attention to people's noneconomic motives that are independent of outcome concerns when explaining the act of cooperation.  相似文献

This paper critically examines the first attempt to offer general statutory protection to United Kingdom whistleblowers. Despite some useful provisions, the paper concludes that the bill is retrogressive, unsophisticated and narrow; and that it will be the legal profession not employees of conscience who will benefit from this instrument if it passes into law. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

This study was designed to analyze the effects of the environment and substrata on the quality of deoxyribonucleic acid (DNA) isolated from evidentiary specimens. The quality of DNA isolated from actual casework specimens was determined by measuring its size by agarose gel electrophoresis. The information obtained could be used to predict the suitability of the DNA in the samples for restriction fragment length polymorphism (RFLP) analysis. The evidentiary specimens chosen for DNA were classified according to substrate (scrapings, plastic bags, synthetics, denim, and carpet) and according to a subjective evaluation of the condition of the stain (soiled, damp, or putrefied) and to its size (small or large). The results show that DNA of sufficient quality and high molecular weight (HMW) can be reliably isolated from bloodstains deposited on evidentiary items which have an unknown environmental history and which have dried onto a variety of substrata. Subsequent RFLP analysis of a selected number of these samples verified that the DNA was suitable for this type of analysis.  相似文献

An isoelectric focusing method is described for typing salivary amylase in liquid saliva and saliva stains. The estimated gene frequencies in a British population, calculated on the basis of three alleles operating at a single locus, were Amy 1, 0.909; Amy 2, 0.065; Amy 3, 0.026. This system may be useful in forensic investigations.  相似文献

The purpose of this study is to examine the participation of criminology and criminal justice graduate departments at the 1977-1979 American Society of Criminology meetings. Results show that institutional prestige. not productivity, is the leading predictor of meeting participation. In addition, meeting participation does not appear to be influenced by meeting site. Finally, it is suggested that criminologists focus more attention upon professional activities in order to facilitate our understanding of criminology as a science.  相似文献

The effects of changes in the minimum drinking ages in various North American jurisdictions are reviewed. The research suggests that although most teenagers have experimented with alcohol, the rates of alcohol consumption and alcohol-related traffic collisions can be increased and decreased with the drinking age control legislation.  相似文献

This article approaches a position of delving into the thoughts of those who commit murder serially. The information comes from a variety of sources which include research literature, theory examination and most importantly, serial murderers themselves. More than 400 cases of serial fatal violence as well as interviews with incarcerated serial killers were utilized. Important issues such as locus of motives, expected gains, victim selection processes, planning of the event, the murder event itself, and organization and disorganization of the kill are also discussed. While admitting that serial killers have never been rehabilitated, a call is directed toward a better understanding of the mind of the serial murderer.  相似文献
