A comprehensive epidemiological study of the involvement of cannabis and ethanol in motor vehicle fatalities in the Province of Ontario, Canada, is described. The study is based on toxicological analyses of blood and, when available, urine specimens. Ethanol was determined by headspace gas chromatography (GC). For cannabis, the methods employed were radioimmunoassays (RIAs) for screening and gas chromatography/mass spectrometry (GC/MS) for the determination of delta-9-tetrahydrocannabinol (THC) in blood. The study sample consisted of 1169 drivers and 225 pedestrians. THC was detected in the blood of 127 driver victims (10.9%) in concentrations ranging from 0.2 to 37 ng/mL, with a mean of 3.1 +/- 5.0 ng/mL. Ethanol was found in 667 driver victims (57.1%), in concentrations ranging from 9 to 441 mg/100 mL, with a mean of 165.8 +/- 79.5 mg/100 mL. For pedestrians, the incidence of THC and ethanol in the blood was 7.6 and 53.3%, respectively. The incidence of THC in the driver victims in this study constitutes an approximately threefold increase over the results of an Ontario study completed in 1979. At least a part of the increase may be attributed to interstudy differences in analytical methodology for cannabinoids.  相似文献

The deterioration of police/citizen relations has had a major impact on the administration of justice. Mutual suspicion, hostility, distrust, and fear have resulted in minimal citizen cooperation and, consequently, an increase in police use of aggressive enforcement procedures. These procedures adversely affect the police as well as the citizenry. Use of aggressive enforcement has two salient consequences: it isolates the police from the citizen, and it generates occupational solidarity among police personnel. Solidarity subsequently increases police/citizen polarization. The process, thus, is circular. The purpose of this study is to empirically investigate the determinants of social isolation and occupational solidarity.To investigate these determinants, a multivariate, multistage conceptual model was developed and analyzed. The findings suggest that the conceptual model, save two minor modifications, fits the data. Policy implications based on these findings are presented and discussed.  相似文献

Landmark reforms     
After more than one hundred years, the future of a unified Probation Service looks bleak in the face of current proposals by the Ministry of Justice to open up the market for rehabilitation services to new providers from the private, voluntary and community sectors.  相似文献

This paper contributes to the normative debate over capital punishment by looking at whether the role of executioner is one in which it is possible and proper to take pride. The answer to the latter question turns on the kind of justification the agent can give for what she does in carrying out the role. So our inquiry concerns whether the justifications available to an executioner could provide him with the kind of justification necessary for him to take pride in what he does. If they cannot, I argue, this sheds some light on their adequacy as justifications. The main argument of the paper is that social control arguments for the death penalty fail to provide an adequate justification. I also give some consideration to retributive justifications. The argument is developed through close attention to the depiction of Albert Pierrepoint in the film, Pierrepoint: The Last Hangman.  相似文献

This article argues that applying the Bayesian logic of process tracing can improve intelligence estimates, appraisals of alternative policy options, and reassessments of whether policies are working as planned. It illustrates these points by demonstrating how more systematic use of this logic could have improved each of these three elements of policymaking regarding the 2003 US military intervention in Iraq.  相似文献
