Traditional methods of volatile detection used by police typically consist of reliance on canine olfaction. However, dogs have some limitations such as cost of training and time of conditioning. The possibility of using parasitic wasps for detecting explosives and narcotics has been developed. Moreover, wasps are cheap to produce and can be conditioned with impressive speed for a specific chemical detection task. We examined the ability of Nasonia vitripennis Walker to learn and respond to methyldisulfanylmethane (DMDS), a volatile discriminator of cadaver. The training aimed to form an association between an unconditioned stimulus (pupae) and the conditioned stimulus (odor source). After the training, the time spent by conditioned wasps in the DMDS chamber was measured. Statistical analysis showed that the increasing concentrations involved an increase in the time spent in the chamber containing DMDS. This study indicates that N. vitripennis can respond to DMDS, which provide further support for its development as a biological sensor.  相似文献

Internet sales of human remains occur despite the existence of laws prohibiting such action in most jurisdictions. The most popular public platform for online sales, eBay, allows users to postskeletal material for sale, largely anonymously and without much fear of legal repercussions. This survey of skeletal sales was conducted 10 years after the first article published about online human remains sales. A review of current laws reveals that, while many states have laws that restrict any sale of human remains, those laws have questionable deterrent effect. Assessing the skeletal material posted for sale provides law enforcement agencies with a necessary starting point to curtail the sale of human remains through enforcement of existing laws. Ultimately, the goal is to stem the commodification of such items and to recover skeletal material, especially that which may be of archaeological or forensic significance, and provide the proper final disposition for such material.  相似文献

The prevalence of cardiac implantable electronic devices (CIEDs), pacemakers and implantable cardioverter defibrillators (ICDs) is increasing. However, postmortem analysis of CIEDs is not performed routinely. Fourteen consecutive CIEDs were analyzed. The indication for and date of implantation, technical data, CIED reprogramming, heart rhythm disturbances, patient demographics and medical consultations were investigated. Death during the first year after implantation was seen in 54%, whereof 71% consulted a physician within 10 days before death. The time of death was attributed to a particular day in 29%. There was a relationship between CIEDs and cause/manner of death in 50%. Although limited by a small sample size, this study advocates the routine postmortem CIED analysis for forensic and clinical purposes in selected cases. Patients with CIEDs seem to show an increased risk of death during the first year after implantation. The analysis of CIEDs can be helpful in evaluating the time/cause/manner of death.  相似文献

This article examines the potential for new front‐of‐pack (FOP) nutrition labeling initiatives to nudge consumers toward healthier food choices. The libertarian‐paternalist approach to policy known as nudge initially developed by Thaler and Sunstein is discussed, with its emphasis on designing spaces (including the space of the food label) to shape the behavior of individuals while not restricting consumer choice or imposing restrictions or penalties on producers. In the context of concerns over diet‐related chronic diseases and obesity, new FOP interpretive nutrition labels have been proposed or implemented in an attempt to shift consumer dietary choices, including the Multiple Traffic Light labeling system in the United Kingdom and the Health Star Rating system in Australia. We identify some of the characteristics, the underlying nutritional philosophies, and the limitations of these FOP labeling schemes. We suggest that the potential of these schemes is compromised by the coexistence on the food label of many other forms of nutrition information and food marketing. Some alternative ways of labeling and communicating the nutritional quality of foods are also discussed.  相似文献

The purpose of this study was to use a modified Delphi methodology study to identify priority actions that can be taken at the individual, local, and national levels to eliminate the stigma surrounding domestic and sexual violence. An expert panel of national organizational leaders provided input about the nature of the stigma surrounding domestic and sexual violence, as well as strategies to end this stigma. The findings were organized into three themes: (a) the social context of the stigma surrounding domestic and sexual violence; (b) the impact of the stigma on resources for victims and survivors; and (c) strategies for eradicating the stigma surrounding domestic and sexual violence. Implications of the study’s findings for research, practice, and advocacy are discussed.  相似文献

Objectives

This study examines the effectiveness of foot patrol in violent micro-places. A large urban police department deployed foot patrol in micro-places (hot spots) for a period of 90 days for two shifts each day. Our objective is to determine whether this activity impacted violent crime in these hot spots and whether spatial displacement of crime occurred.

Methods

Eight eligible foot beat locations were set by examining crime rates for previous years in order to identify micro-places of high criminal activity. We employed a quasi-experimental design comparing the four treatment to the four control areas, estimating panel-specific autoregressive models for 30 weeks prior to and 40 weeks after the treatment.

Results

Time series models revealed statistically significant reductions in violent crime in the micro-places receiving foot patrol treatment, while no such reductions were observed in the control areas. The deterrent effect, however, was short and dissipated quickly. Control areas did not experience any crime prevention benefit during this time period. No evidence of crime displacement to spatially contiguous areas was detected.

Conclusions

This contributes to the growing body of knowledge that focused police strategies within hot spots impact violent crime. Specifically, the implementation of foot patrol in high crime hot spots led to measurable reductions in aggravated assaults and robberies, without displacing crime to contiguous areas.

ABSTRACT

Ten years after the coming into force of the EU–South Africa Strategic Partnership, this article takes stock of this partnership. Our aim, within this special issue, is to assess the EU’s perspective on its strategic partnership with South Africa, and in particular to look at economic and development cooperation within the partnership and to what extent European expectations of closer engagement have been met. Our analysis shows that economic interests have remained central to bilateral relations and the strategic partnership, even if some potential for economic engagement has remained unexploited. At the same time, the relationship has been quite tense in recent years, as bilateral ‘affection’ at the political level has waned. The implications for the partnership are weighed.  相似文献

This article examines one of the most long-established methods of fund-raising for charitable causes in the UK – public charitable collections – and looks at changing patterns in this method of fund-raising in recent years. There have been changes both in the method of collection, which now extends beyond cash donations collected by unpaid volunteers to direct debits and credit card donations collected by paid collectors, and also in the chosen locations for collections, with a preference for supermarkets and other off-street sites. These changes have brought with them difficulties in the regulation of such collections. The article gives a brief overview of current legislative provisions in the UK and the proposed new measures for England and Wales. It examines some of the practical problems involved with the implementation of legislative provisions, and considers some alternative ways of combating potential fraud.  相似文献
