Using micro-X-ray fluorescence (MXRF), a novel means of detecting fingerprints was examined in which the prints were imaged based on their elemental composition. MXRF is a nondestructive technique. Although this method requires a priori knowledge about the approximate location of a print, it offers a new and complementary means for detecting fingerprints that are also left pristine for further analysis (including potential DNA extraction) or archiving purposes. Sebaceous fingerprints and those made after perspiring were detected based on elements such as potassium and chlorine present in the print residue. Unique prints were also detected including those containing lotion, saliva, banana, or sunscreen. This proof-of-concept study demonstrates the potential for visualizing fingerprints by MXRF on surfaces that can be problematic using current methods. 相似文献

The article explores the extent, the institutional mechanisms and economic consequences of economically motivated bribery in the Norwegian (and British) oil industry. It focuses on corruption directed against middle-level management in the oil companies. The empirical part of the study is partly based on public information collected from court cases, mainly from British courts; and partly based on systematic interviews of security experts in Norwegian and international oil companies, and British and Norwegian police. 相似文献

Homicide-suicide forms a distinct form of homicide. An analysis of cases in the Yorkshire and Humberside region of England between 1991 and 2005 revealed 37 episodes with 42 victims. Previous studies have shown a high rate of use of firearms. Over the last 2 decades firearms legislation has become more restrictive. In this study all assailants were male, mean age 46.8 years. The commonest method of homicide was strangulation (36%) with 16% killed by firearms. This is a reduction compared with a previous study in the same region. All killers who shot their victims killed themselves with firearms. There were no multiple killings with firearms in this study and no stranger killings. Hanging was the commonest method of suicide. During the same period the use of firearms as a method of homicide increased in England and Wales with handguns, the most common weapon. Nationally, suicide after homicide has remained at a similar rate over the half century and is an uncommon phenomenon. Firearms use remains low in both homicide and homicide-suicide episodes in England, and further analysis is required to determine changes in patterns of killing. 相似文献

This research investigates low religiosity as a predictor of violent victimization. The theoretical framework the authors present here posits that religiosity should help structure daily activities in such a way as to (a) limit exposure to offenders by encouraging contact with peers who are less deviant, (b) lessen one's target suitability by inhibiting grievance-causing delinquent activity, and (c) enhance guardianship by fostering stronger bonds with parents and school. Thus, although researchers expect religion to be a bivariate predictor of violent victimization, its influence should be indirect. The authors investigate these claims using two waves from the public-use version of the National Longitudinal Study of Adolescent Health (Add Health). The results indicate that religiosity is a correlate of violent victimization. Consistent with these theoretical claims, the effect of religiosity is not direct, but instead occurs indirectly primarily through its influence on self-reported delinquency and peer deviance. 相似文献
