This study reports an evaluation of the Drink-Impaired Drivers program in the English and Welsh probation service. Participants were adult male offenders who had been convicted of a drink-driving offence and were serving community sentences. The 1-year drink-drive reconviction rates were compared for offenders who completed the program, offenders who started but did not complete the program, and a comparison group who were not allocated to the program. At 1-year follow-up, there was no reconviction among offenders who had completed the program. Multivariate analysis showed that the noncompleters had a significantly higher rate of reconviction than the completers and comparison group. 相似文献

Non-destructive identification and subsequent age estimation of blood stains are significant steps in forensic casework. The latter can provide important information on the temporal aspects of a crime. As previously shown, visible spectroscopy of blood stains on white backgrounds can successfully be used for their identification and age estimation. The use of this technique however, is hampered by dark backgrounds. In the present study the feasibility to use near infrared (NIR) spectroscopy was evaluated for blood stain identification and age estimation on dark backgrounds. Using NIR reflectance spectroscopy, blood stains were distinguished from other substances with 100% sensitivity and 100% specificity. In addition, Partial Least Squares Regression analysis was applied to estimate the age of blood stains on colored backgrounds. The age of blood stains up to 1 month old was estimated successfully with a root mean squared error of prediction of 8.9%. These findings are an important step toward the practical implementation of blood stain identification and age estimation in forensic casework, where a large variety of backgrounds can be encountered. 相似文献

A collaborative study on Raman spectroscopy and microspectrophotometry (MSP) was carried out by members of the ENFSI (European Network of Forensic Science Institutes) European Fibres Group (EFG) on different dyed cotton fabrics. The detection limits of the two methods were tested on two cotton sets with a dye concentration ranging from 0.5 to 0.005% (w/w). This survey shows that it is possible to detect the presence of dye in fibres with concentrations below that detectable by the traditional methods of light microscopy and microspectrophotometry (MSP). The MSP detection limit for the dyes used in this study was found to be a concentration of 0.5% (w/w). At this concentration, the fibres appear colourless with light microscopy. Raman spectroscopy clearly shows a higher potential to detect concentrations of dyes as low as 0.05% for the yellow dye RY145 and 0.005% for the blue dye RB221. This detection limit was found to depend both on the chemical composition of the dye itself and on the analytical conditions, particularly the laser wavelength. Furthermore, analysis of binary mixtures of dyes showed that while the minor dye was detected at 1.5% (w/w) (30% of the total dye concentration) using microspectrophotometry, it was detected at a level as low as 0.05% (w/w) (10% of the total dye concentration) using Raman spectroscopy. This work also highlights the importance of a flexible Raman instrument equipped with several lasers at different wavelengths for the analysis of dyed fibres. The operator and the set up of the analytical conditions are also of prime importance in order to obtain high quality spectra. Changing the laser wavelength is important to detect different dyes in a mixture. 相似文献

Preliminary research suggests that child abuse is indirectly associated with female-perpetrated intimate partner violence
via posttraumatic stress disorder (PTSD) symptoms and anger. To date, however, no known studies have investigated these relationships
for physical and psychological dating violence within a female college sample. Therefore, the purpose of the current study
was to examine the impact of child abuse history, PTSD symptoms, and anger arousal on female-perpetrated physical and psychological
dating violence. Female undergraduates (N = 496) completed measures of child abuse, PTSD symptoms, anger arousal, and dating violence perpetration as part of a larger
trauma and violence study. Results indicated that child abuse directly predicted female-perpetrated physical and psychological
dating violence and indirectly impacted female-perpetrated physical and psychological dating violence via PTSD symptoms and
anger arousal. The direct relationships between PTSD symptoms and female-perpetrated physical and psychological dating violence
were nonsignificant after controlling for the effect of anger arousal. 相似文献

Though still relatively infrequent, the issuing of dissenting and concurring opinions is becoming more common in international investment arbitration. This paper reviews the reasons for delivering separate opinions envisaged in the bibliography on investment arbitration, comparing these with practices in the related area of commercial arbitration. Fourteen recent separate opinions appended to ICSID arbitration awards and decisions are then analysed to determine how the arbitrators themselves explain why they have taken the drastic step of issuing a separate opinion. Potential areas of convergence between investment arbitration and commercial arbitration practice will be addressed. 相似文献

In R (on the application of Friends of the Earth Ltd and others) v Heathrow Airport Ltd the UK Supreme Court allowed an appeal against the Court of Appeal's decision that there had been a series of legal errors in the designation of the Airport National Policy Statement. This case note analyses the case from an ‘internal’ doctrinal perspective and argues that the Supreme Court could have engaged more explicitly with the legal issues that arise from climate change legislation for administrative law adjudication. For courts to adjudicate well in such circumstances they need to be prepared to develop administrative law doctrine, particularly in light of the issues of integrating climate change into public decision-making and of scientific/policy uncertainty which lie in the background of climate change legislation. 相似文献

In many established democracies, partisan attachments play a central role in guiding citizens’ attitudes as well as their political behaviour. Most importantly, partisanship has an effect on what party citizens vote for on Election Day. In general, highly politically sophisticated citizens are more likely to identify with a party compared to the less politically sophisticated. This article argues that the strength of an individual’s partisan attachment varies considerably over time. More specifically, it finds that party attachments are stronger when Election Day is close. The less politically sophisticated in particular benefit from such an effect and develop stronger attachments at election times. 相似文献
