A study was performed to acquire urine, serum and oral fluid samples in cases of suspected driving under the influence of drugs of abuse. Oral fluid was collected using a novel sampling/testing device (Dr?ger DrugTest System). The aim of the study was to evaluate oral fluid and urine as a predictor of blood samples positive for drugs and impairment symptoms. Analysis for cannabinoids, amphetamine and its derivatives, opiates and cocaine was performed in urine using the Mahsan Kombi/DOA4-test, in serum using immunoassay and gas chromatography-mass spectrometry (GC-MS) confirmation and in oral fluid by GC-MS. Police and medical officer observations of impairment symptoms were rated and evaluated using a threshold value for the classification of driving inability. Accuracy in correlating drug detection in oral fluid and serum were >90% for all substances and also >90% in urine and serum except for THC (71.0%). Of the cases with oral fluid positive for any drug 97.1% of corresponding serum samples were also positive for at least one drug; of drug-positive urine samples this were only 82.4%. In 119 of 146 cases, impairment symptoms above threshold were observed (81.5%). Of the cases with drugs detected in serum, 19.1% appeared not impaired which were the same with drug-positive oral fluid while more persons with drug-positive urine samples appeared uninfluenced (32.7%). The data demonstrate that oral fluid is superior to urine in correlating with serum analytical data and impairment symptoms of drivers under the influence of drugs of abuse.  相似文献

Poppy seeds contain morphine in different amounts. Reported concentrations are up to 294 mg morphine/kg poppy seeds. Since penalties based on Street Traffic Law (parapgraph 24a StVG) in Germany (administrative offence) require definitive proof of morphine in blood samples, and the "Grenzwertkommission" in consultation with the Ministry of Transportation recommended a threshold of free morphine of 10 ng/mL, the question arose whether the consumption of poppy seeds can lead to a blood concentrations equal or higher than 10 ng/mL of free morphine. Therefore, five volunteers ate poppy seed products (50 mg morphine/kg poppy seeds). In urine, all on-site tests were enzyme immunologically positive for opiates and were positive to morphine by GC/MS. All the blood samples were negative to morphine by EIA and to free morphine by GC/MS. However, after hydrolysis, morphine was detected by GC/MS in all cases. Accordingly, in Germany, penalties based on parapgraph 24a StVG are not likely to cause road users any concerns should they have consumed poppy seeds. Driver Licensing Authorities, however, should be advised of this problem to avoid unjustified legal measures.  相似文献

Zusammenfassung  Die genetische Vielfalt ist oft übersehenes Schutzgut des Naturschutzrechts. Sie ist der Grund, warum zunehmend gefordert wird, Anpflanzungen nur mit gebietseigenem Pflanzmaterial durchzuführen. Rechtliche Probleme stellen sich hier an der Schnittstelle von Naturschutz- und Vergaberecht. Soll n?mlich bei der ?ffentlichen Auftragsvergabe zur Anpflanzung von Geh?lzen oder beim Einkauf von Pflanzmaterial nicht gegen vergaberechtliche Vorschriften versto?en werden, bedarf es hinreichender, im Naturschutzrecht verwurzelter Gründe, um ?ffentliche Ausschreibungen ausschlie?lich auf gebietseigenes Pflanzmaterial einzuengen. Diesen naturschutzrechtlichen Verpflichtungen geht der vorliegende Beitrag nach.  相似文献

Prices in illegal drug markets are difficult to predict. Based on qualitative interviews with 68 incarcerated drug dealers in Norway, we explore dealers’ perspectives on fair prices and the processes that influence their pricing decisions. Synthesized through economic sociology, we draw on perspectives from traditions as different as behavioral economics and cultural analysis to demonstrate how participants in illicit drug distribution base their pricing decisions on institutional context, social networks, and drug market cultures. We find that dealers take institutional constraints into consideration and search for niches with high earnings and low risks. The use of transactions embedded in social networks promotes a trusting form of governance, which enables strategic network management and expedient distribution but also uncompetitive pricing. Finally, dealers’ pricing decisions are embedded in three different cultures narratives: business, friendship, and street cultural stories, with widely varying implications for prices. Our findings demonstrate how an economic sociology of illicit drug distribution can extend insights from behavioral economics and cultural studies into a coherent criminology of illegal drug markets.  相似文献

The Euro zone was caught unprepared by the financial crisis originating in the USA followed by the recession. Severe flaws in the designs hidden by the ??good?? years surfaced calling for action. After a good deal of fumbling, the Euro zone moves towards a fiscal union anchored in acceptance of a ??German?? economic model??low inflation, low deficits, and debts. The Euro will survive with two major changes. The integration will be stronger and the core countries in the Euro zone will exercise stronger leadership raising awkward policy decision for the skeptical members of the EU, but outside the Euro.  相似文献

Scholars traditionally claim that unanimity rule is more capable of producing Pareto optimal outcomes than majority rule. Dougherty and Edward (Public Choice 151(3):655–678, 2012) make the opposite claim assuming proposals are either random, sincere, or strategic. We test these competing hypotheses in a two-dimensional framework using laboratory experiments. Our primary results suggest: (1) majority rule enters the Pareto set more quickly than unanimity rule, (2) majority rule leaves the Pareto set at the same rate as unanimity rule, and (3) majority rule is more likely to select a Pareto optimal outcome than unanimity rule at the end of the game.  相似文献

A recent change in Danish cannabis control policy has had significant implications for the structure of the retail-level cannabis market in Copenhagen. A process of restructuring following an crackdown on ‘Pusher Street’ has involved at least four people getting shot and killed in what police describe as struggles for market shares. Combating the retail cannabis market was a top three priority for the Copenhagen police. The shift in policy started in 2004 when possession for personal use was up-penalized, from a discriminatory warning to an obligatory fine of 70 euros which was quadrupled in 2007. The law was immediately followed by an extensive police crackdown on Christiania’s open retail-market. Christiania has had a cannabis market for 32 years. As cannabis use rates rose throughout the ‘90’s the market flourished. On a given day it’s estimated turnover was around 20 k, about twothirds of the total market in Copenhagen. On the 16th of May 2004 police raided ‘Pusher Street’ and arrested 60 dealers and their helpers along with 20 people accused of forming an organized lookout corps. After the initial raid police implemented a zero-tolerance zone in the area and targeted users in a deterrent effort issuing a total of 4834 fines in a year. Maintaining the zero tolerance zone has so far involved 12 big confrontations with the inhabitants of Christiania. 114 police officers have been injured and 29 formal complaints of police conduct have been lodged with the State Attorney. Following the crackdown the cannabis market adapted by dispersing and applying new methods for retail dealing.  相似文献

The following is an exchange concerning the concept of ‘illiberal moderates’ and its implications for a new global architecture as well as for a worldview that sees the evolution of a global core of shared values which favour domestic and international security, in sharp contrast to the ‘clash of civilizations’ thesis. The original statement was published in the Cambridge Review of International Affairs (Etzioni 2006). A more extensive treatment can be found in Part III of Security first: for a muscular, moral foreign policy (Etzioni 2007b), which examines texts of four religious and two secular belief systems as well as review of relevant public opinion polls and ‘traveller notes’. Here follows a brief summary of the main thesis, followed by comments from prominent scholars and Etzioni's response to these comments.  相似文献
