Despite its difficulties and inconsistencies in framing those practices andconducts recently unveiled by the press and judicial investigations whichhave caused considerable public discontent, the penal definition ofcorruption still highlights an interesting conceptual diversity across spaceand time that should not be overlooked. Most official discussions about andreferences to corruption and its volume are still framed within these hardparameters. It is, therefore, important to look at the intricacies ofcorruption as a crime in order to understand the virtues and failures ofnational repressive efforts. While crime statistics are of limited use for itsmeasurement, they can nevertheless help to interpret the way corruptionhas been treated through repressive instruments cross-nationally over aperiod of time.The aim of this paper is to assess the dynamics of the various processes ofsetting and revising penal standards to the conduct of office holders and theresults observable from the application of corruption and related offencesacross countries with different legal traditions. 相似文献

The impact of high temperatures (24 to 39 degrees C) and low to moderately high humidities (20 to 70%) on the applicability of TLC systems for drug identification was studied during a 6 month climatologic cycle in Burkina Faso (West Africa). In general, the Rf values as observed on the plates were found to be substantially affected as compared with values obtained at temperate climates. Some TLC systems were more affected than others and the largest deviations of up to 30 Rf units were at low humidities. Tropical conditions also had a negative effect on the reproducibility of Rf values. However, when an Rf-correction procedure was applied, using reference mixtures of known drugs on each plate, accuracy as well as reproducibility of the resulting Rfc values were drastically improved and data thus corrected were found to be compatible with existing TLC data bases developed under moderate climatological conditions. The impact of high to extremely high humidities (70 to 100%) remains to be investigated. 相似文献

Studies of restorative justice programs continue to provide a review of restorative justice practice and impact. While this body of research is growing, many questions remain regarding the impact of restorative justice in reducing crime. By relying on individual and community-level data, the present study examined how offense type and poverty level influenced program completion and recidivism among juveniles in a restorative justice program. This study also examined the relationship between program completion and recidivism. Findings revealed that status offenders in the restorative justice program were more likely to complete the program and less likely to recidivate than status offenders in the comparison group. In addition, property offenders in the restorative justice program were less likely to recidivate than property offenders in the comparison group. Poverty level at the community-level had a significant influence in both program completion and recidivism. 相似文献

This paper describes the analytical methodology for the determination of MDMA, MDA, MDEA and MBDB in oral fluid. After a liquid–liquid extraction, the analysis was carried out by high performance liquid chromatography (HPLC), with fluorescence detection. The detector wavelength was fixed at 285 nm for excitation and 320 nm for emission. The mobile phase, a mixture of phosphate buffer (pH = 5) and acetonitrile (75:25), and the column, Kromasil 100 C8 5 μm 250 mm × 4.6 mm, allowed good separation of the compounds in an isocratic mode in only 10 min. The method was validated and showed good limits of detection (2 ng/mL) and quantitation (10 ng/mL) for all the amphetamine derivatives. No interfering substances were detected. A stability study of these compounds in oral fluid stored at three different temperatures (−18, 4 and 20 °C) over 10 weeks was conducted, showing a time-dependent degradation of the four compounds. 相似文献

Drug trade is widely seen as a phenomenon rather new to the Netherlands. However, at the beginning of the 20th century the Dutch pharmaceutical industries were already extensively involved in the production of both opiates and cocaine, and they went on exporting large quantities of these drugs after the Opium Act (1919) took force. Until the 1960s, arrests were not at all common, and these largely affected minority groups like Chinese opium smokers and black marijuana users. Since then, drug control efforts have increased by leaps and bounds. At first, cannabis was the main target; then the focus turned to heroin, and that was later joined by cocaine. This paper traces the history of the drug trade and drug control in the Netherlands, with emphasis on their development in Amsterdam. The conclusion is reached that, in spite of drastic changes in both drug trade and drug control, certain ideologies, constructs and strategies have remained remarkably stable. 相似文献

Social media is changing not only the atmosphere in which international negotiations take place; it is also changing the very substance of the deals. Because of the pace and proliferation of social media, negotiators must read “weak signals” early on—and anticipate a quickly organized, highly motivated opposition. However, diplomatic negotiators still lack the tools to engage in this sort of anticipatory strategy design. This article examines two recent cases, one involving the Transatlantic Trade and Investment Partnership and the other involving a German Constitutional Court’s ruling on the European Central Bank’s Public Debt Purchasing Program, in which social media had a highly disruptive, unanticipated impact on international negotiations—to the point of forcing negotiators’ hands—and suggests institutional remedies to better anticipate the catalytic impact of advancing technology on diplomatic interactions. 相似文献
