Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.  相似文献

Defining risk   总被引:6,自引:0,他引:6  
Risk is the focal topic in the management of many activities and technologies. For that management to be successful, an explicit and accepted definition of the term risk is essential. Creation of that definition is a political act, expressing the definers' values regarding the relative importance of different possible adverse consequences for a particular decision. Those values, and with them the definition of risk, can change with changes in the decisionmaker, the technologies considered, or the decision problem. After a review of the sources of controversy in defining risk, a general framework is developed, showing how these value issues can be systematically addressed. As an example, the approach is applied to characterizing the risks of six competing energy technologies, the relative riskeness of which depends upon the particular definition used.  相似文献

This paper examines the participation of member states of the Caribbean Community (CARICOM) in the World Trade Organisation (WTO)’s dispute settlement system and its associated negotiations. In so doing, it highlights the dispute settlement system’s important contribution to the WTO and the need for CARICOM member states to engage more actively with this aspect of the WTO’s work. The paper concludes by articulating some of the lessons learnt from CARICOM member states’ experiences to date and offering some concrete suggestions on how the region can improve its current record of engagement.  相似文献

Correctly assessing heart weight can be critical at postmortem examination. The current international guidelines advocate using the short-axis method in dissecting the heart and the heart weighed when the blood is emptied. However, it did not specify at what point the heart should be weighed or how the blood should be emptied. This study compared heart weights at three different time points during the heart examination (immediately after dissecting out of the pericardial sac with blood still in chambers, blood washed/removed from heart chambers without the heart opened, and the heart completely opened, blood emptied, and pad dried). This was to illustrate the variation in measurement and potential errors when the heart is weighed at different time of dissection. The results show that there were statistical and clinical significant differences between the heart weights at each weighing points. We recommend the heart to be completely dissected with any blood and residual washing/rinsing water emptied before being weighed. Although performed in this study, the effect of pad drying the heart on heart weight was not explored and was a limitation in this study.  相似文献

This article focuses on the discursive construction in Britain of a middle-class moral panic occasioned by the distress caused to self-styled 'responsible mortgage borrowers' by falling house prices. In the context of the move towards asset-based welfare the sub-prime crisis manifested itself most obviously in the popular consciousness as a threat to housing market wealth. The Labour government used the political space opened up by the narrative of middle-class moral panic in order to protect banks' balance sheets from the consequences of their own failed investments in mortgage-backed securities. The ensuing arrangements immunised banks from the implications of market self-regulation in the first-phase response to the sub-prime crisis while simultaneously allowing them to continue to impose the experience of market self-regulation on their customers. An increasingly asymmetric approach to banking regulation has arisen analogous to that which Karl Polanyi associated with the contradictory co-existence of market and non-market forms.  相似文献
