Quartz sand surface texture analysis has been automated for the first time for forensic application. The derived Basic Image Features (BIFs) provide computer-generated texture recognition from preexisting data sets. The technique was applied to two distinct classification problems; first, the ability of the system to discriminate between (quartz) sand grains with upturned plate features (indicative of eolian, global sand sea environments) and grains that do not exhibit these features. A success rate of grain classification of 98.8% was achieved. Second, to test the ability of the computer recognition system to identify specific energy levels of formation of the upturned plate surface texture features. Such recognition ability has to date been beyond manual geological interpretation. The discrimination performance was enhanced to an exact classification success rate of 81%. The enhanced potential for routine forensic investigation of the provenance of common quartz sand is indicated. 相似文献

Anomie is a highly prominent theoretical construct in macro-social, particularly cross-national, criminological inquiry. Yet despite its prominence, it has proven to be quite elusive with regard to its measurement and, hence, making it nearly impossible to test theoretical hypotheses regarding its predictive efficacy. Although the concept, whether derived from Merton's classic conceptualization or from its current incarnation in the form of institutional anomie as developed by Messner and Rosenfeld, is multidimensional and complex in its theoretical structure, most researchers have attempted to operationalize it through simple, single-item, often surrogate/proxy measures. The present research note attempts to develop a measure that is more consistent with its multidimensional and complex nature. This more complex operationalization is then examined with regard to its efficacy at predicting cross-national levels of both homicide and theft. Our results suggest that that this new operationalization has considerable predictive efficacy, accounting for approximately one third of the variation in the cross-national level of both homicide and theft. 相似文献

Other papers in this edition of the European Journal of Criminal Policy and Research use mainly statistics collected through the European Sourcebook on Crime and Justice Statistics but there are many other
sources of international statistics collected by different agencies for different purposes. This paper critically examines
the main current and planned collections of comparative data within the European community and wider international bodies.
Full Web references are given of available questionnaires and publications where these exist. It also discusses the importance
of comparative data generally and pitfalls in its interpretation and examines the guidelines published by international bodies
to assist with data collection on crime and justice. Finally, the future of comparative data collections is discussed and
recommendations are made. 相似文献

Shifts in the national cultural identity of the US have been reflected in shifts in the US?? dominant constitutional narratives. For the United States, ??inter-legality?? has been less a matter of dealing with alternative non-state legal narratives than of contending with constantly arising and competing narratives about the ??correct?? nature of the ??official?? legal order of the state. The US Supreme Court has claimed to have the ??last word?? in resolving these arguments but because that Court is so often sharply divided and because the Court membership and the nature of its ??last words?? changes so often, where a significant element of the society seeks to advance its ideas and interests, it will often do so in legal and constitutional terms. As the national culture undergoes changes, a competing constitutional narrative may gain ground and even ultimately prevail, at least for a time, and achieve Supreme Court ??endorsement?? for its claims. 相似文献

Although much prior work has examined the influence of extralegal factors on jury capital sentencing decision-making, the influence of defendant sex has been largely omitted from previous investigations. Using propensity score matching methods, the current study analyzes data from the North Carolina Capital Sentencing Project to examine whether “sex matters” in capital sentencing. Findings demonstrated that prior to matching there was a significant difference in the likelihood of receiving the death penalty for female and male defendant cases; however, after matching cases on an array of legal and extralegal case characteristics, these differences were no longer significant. Further results revealed that male defendants’ cases included different aggravating and mitigating factors than female defendants’ cases and that female defendants had limited “paths” to capital trials. Findings suggest that any apparent sex effects that are observed in capital sentencing stem from real differences in the case characteristics found in female and male defendants’ cases rather than any direct effects of defendant sex on jury decision-making. Study limitations and implications for death penalty research are also discussed. 相似文献
