Is There a Relationship Between Street Heroin Purity and Drug‐Related Emergencies and/or Drug‐Related Deaths? An Analysis from Vienna,Austria* 总被引:2,自引:0,他引:2

This study examines the quality of street heroin seized in Vienna in 1999 and whether there was a relationship between the purity of street heroin and the number of heroin-related emergencies as well as the number of heroin-related deaths. Street heroin confiscated by the Viennese police, run-sheets of drug-related emergencies, and postmortem reports of drug-related deaths in Vienna in 1999 were analyzed. A total of 415 retail samples with a total weight of 128.02 g contained a median percentage of 6.5% diacetylmorphine (range: 0.0-47.0%). All the samples contained a diluent, mainly lactose, as well as adulterants, such as caffeine and/or paracetamol. During the study period, 75 heroin-related deaths and 387 heroin-related emergencies were registered in Vienna. Time-series analysis revealed no statistically significant relationship between the rate of heroin-related incidents and the diacetylmorphine concentration of street heroin samples confiscated in Vienna in 1999. The widely held belief that the number of heroin-related deaths could be explained simply through fluctuations in the purity of street heroin could not be substantiated, even though the results of this study do not rule out an association between the purity of heroin and heroin-related deaths/emergencies. 相似文献

Objectives
An important indicator of discrimination in the criminal justice system is the degree to which race differences in arrest account for racial disproportionality in prisons (“accountability”). A recent National Academy of Sciences (NAS) study raised concerns by reporting low and declining estimates of accountability. Our improved measure accounts for unreported Hispanic arrestees. We measure accountability at intermediate stages, including commitments to prison and time served. We also use victim reports to extend accountability from arrest to differential involvement in violent crimes.Methods
Our methods utilize information on self-reported racial identity of Hispanic prisoners to provide more accurate comparison with the race of arrestees. We also assess accountability for 42 individual states and 4 regions.Results
Our national estimate of accountability is close to previous estimates and much higher than those in the NAS report. Accountability is high for the serious violent crimes of murder and rape, and low for drug trafficking, drug possession, weapons, and aggravated assault, which involve more discretion in arrest, labeling and charging.Conclusions
Our more accurate accountability results contradict the NAS report of low and declining accountability. Regional accountability estimates show no consistently stronger or weaker region. We also show a corrected national estimate of the ratio of black-to-white incarceration-rates has dropped from 6.8 in 1990 to 4.7 in 2011, an important correction to concerns of increasing discrimination. Reports of offenders’ race by victims and arrestees’ race are found to be close, supporting use of arrest as an indicator of involvement in violent crimes.133.

Im deutschen Umweltrecht finden sich an verschiedenen Stellen Sonderregelungen für Vorhaben der Landesverteidigung. Ausgehend von der Fragestellung, welche Vorhaben hiervon erfasst sind, werden nachfolgend die wichtigsten dieser Sonderregelungen vorgestellt. Die Untersuchung beschränkt sich dabei auf Bestimmungen zum medialen Umweltschutz, der die klassischen Umweltmedien Boden, Wasser und Luft zum Regelungsgegenstand hat

To meet its obligations accepted in the Kyoto Protocol cost effectively, the European Union introduces a scheme of Greenhouse Gas Allowance Trading for its member states. This paper evaluates the cost effectiveness, ecological accuracy and dynamic incentives of this approach.The EU-emissions trading constitutes an important shift in the paradigm of environmental policy, from command and control to a market based approach. Still, the EU-system does not fully realize the economic potential of the transferable discharge permit policy. Especially, the limited scope of trading regarding geography, pollutants, sectors and activities reduces the quality of the system. Moreover, the EU-Directive is unspecific in many respects and it leaves many decisions defining the rules of the game to the individual member state. Uncertainty and heterogeneity increase transaction cost and thereby hamper the effectiveness of the system.JEL Classification: Q54, Q58, K32 相似文献
