As part of the project Impaired Motorists, Methods of Roadside Testing and Assessment for Licensing (IMMORTAL) under the European Commission's Transport RTD Programme of the 5th Framework Programme [I.M. Bernhoft, Drugs in accidents involved drivers in Denmark, D-R4.3 of the project Impaired Motorists, Methods Of Roadside Testing and Assessment for Licensing (IMMORTAL), www.immortal.or.at, 2005], a study regarding drugs in accident-involved drivers was carried out in Denmark. The main objectives of this study were: (1) to collect and analyse samples from injured drivers for the presence of drugs; (2) to give an indication whether drugs may have contributed to traffic accidents; and (3) to get information on the drug-positive drivers and their drug use. This paper focuses on objective 1. Injured drivers who were treated in hospital were asked to give a saliva sample, a blood sample or both. The samples were screened for the following substances: opiates, amphetamines, methamphetamines, incl. MDMA (ecstasy), cannabinoids and metabolites, cocaine and metabolites and benzodiazepines. Screenings were carried out by means of Cozart Microplate EIA kit. Positive screenings were confirmation analysed by gas chromatography–mass spectrometry (GC–MS) or liquid chromatography/tandem mass spectrometry (LC/MS/MS). In total, 26 out of 330 patients were confirmed positive for one or more of the six drug groups. However, three patients were excluded from the survey for various reasons. Of the remaining 23 drug-positive patients 15 were found positive for one drug group, and in five of these cases alcohol was present in a concentration over the legal limit in Denmark (0.05%). The other eight patients were found positive for two drug groups, and in four of these cases, alcohol was also present in a concentration over the legal limit. Alcohol was found both in combinations with medicinal drugs, with illegal drugs and with both. Based on the saliva or blood concentrations, we estimate that there is a strong suspicion of impairment in 9 out of 23 cases, and in another six cases it was likely that the drivers were impaired. 相似文献

德国土地征收中的公共利益 总被引:2,自引:0,他引:2
德国《基本法》第14条将所有权作为宪法基本权利予以保护。该条公共利益条款的本质出发点是保护私人所有权。公共利益概念在德国土地征收法上依据通说认为应作狭义理解,非所有公共利益均可满足征收法上的要件。部门法对公共利益有明确规定。学说和实务界对公共利益概念主要在负面达成了一致。就所谓的商业征收并未一般性否定。公共利益本身也与征收的必要性紧密相关。 相似文献

20世纪70年代由于监狱人满为患,重新犯罪率持续不降,很多国家开始在行刑领域进行改革。其基本内容包括:拓宽行刑目的,从矫正目的论发展到矫正、惩罚、帮助罪犯重返社会与剥夺多元目的论;改革监狱管理制度,从实施累进处遇制发展到推行危险管理制度;变革矫正制度,将"传统矫正"制度发展为"项目矫正"。我国需要研究国际社会在行刑领域的行刑变革理论与实践。 相似文献

There were 13,176 roadside drug tests performed in the first year of the random drug-testing program conducted in the state of Victoria. Drugs targeted in the testing were methamphetamines and Δ9-tetrahydrocannabinol (THC). On-site screening was conducted by the police using DrugWipe®, while the driver was still in the vehicle and if positive, a second test on collected oral fluid, using the Rapiscan®, was performed in a specially outfitted “drug bus” located adjacent to the testing area. Oral fluid on presumptive positive cases was sent to the laboratory for confirmation with limits of quantification of 5, 5, and 2 ng/mL for methamphetamine (MA), methylenedioxy-methamphetamine (MDMA), and THC, respectively. Recovery experiments conducted in the laboratory showed quantitative recovery of analytes from the collector. When oral fluid could not be collected, blood was taken from the driver and sent to the laboratory for confirmation. These roadside tests gave 313 positive cases following GC–MS confirmation. These comprised 269, 118, and 87 cases positive to MA, MDMA, and THC, respectively. The median oral concentrations (undiluted) of MA, MDMA, and THC was 1136, 2724, and 81 ng/mL. The overall drug positive rate was 2.4% of the screened population. This rate was highest in drivers of cars (2.8%). The average age of drivers detected with a positive drug reading was 28 years. Large vehicle (trucks over 4.5 t) drivers were older; on average at 38 years. Females accounted for 19% of all positives, although none of the positive truck drivers were female. There was one false positive to cannabis when the results of both on-site devices were considered and four to methamphetamines. 相似文献

The frequency of medico-legally examined fatal poisonings in 2007 among drug addicts was investigated in five Nordic countries; Denmark, Finland, Iceland, Norway, and Sweden. The number of deaths, age, sex, place of death, main intoxicant, and other drugs present in blood samples were recorded to obtain national and comparable Nordic data, as well as data to compare with earlier studies in 2002, 1997, and 1991. Norway had the highest incidence of drug addict deaths by poisoning followed by Denmark, with 8.24 and 6.92 per 100,000 inhabitants, respectively. The death rates in Finland (4.02), Iceland (4.56), and Sweden (3.53) were about half that of Norway and Denmark. Compared with earlier studies, the death rates were unchanged in Denmark and Norway, but increased in Finland, Iceland, and Sweden. In all countries, fewer deaths (29-35%) were recorded in the capital area compared with earlier studies. Females accounted for 11-19% of the fatal poisonings. Iceland deviates with a more equal distribution between men and women (40%). Deaths from methadone overdoses increased in all Nordic countries, and methadone was the main intoxicant in Denmark in 2007, accounting for 51% of the poisonings. In Norway and Sweden, heroin/morphine was still the main intoxicant with a frequency of 68% and 48%, respectively. In Iceland, 3 deaths each were due to heroin/morphine and methadone, respectively. Finland differs from other Nordic countries in having a high number of poisonings caused by buprenorphine and very few caused by heroin/morphine. The total number of buprenorphine deaths in Finland doubled from 16 in 2002 to 32 in 2007, where it constituted 25% of deaths. The general toxicological screening program showed widespread multi-drug use in all countries. The median number of drugs per case varied from 3 to 5. The most frequently detected substances were heroin/morphine, methadone, buprenorphine, tramadol, amphetamine, cocaine, tetrahydrocannabinol, benzodiazepines and ethanol. 相似文献

In this paper, we reply to Taylor''s (2015) peer commentary on consent-in-escrow. Specifically, we clarify the utility of this novel approach, the way in which it minimizes risks to participants, and how it differs from existing opt-out methods. We further explore its potential use in fields beyond disaster research. 相似文献

在认定黑社会性质组织时,应内看其组织特征,外看其行为特征。黑社会性质组织通常在一定区域或行业范围内,以暴力为后盾,通过使用或威胁使用暴力等手段,依靠犯罪组织的淫威大肆进行敲诈勒索、欺行霸市、寻衅滋事、故意伤害等违法犯罪来获利。具备政治保护伞是黑社会性质组织的重要特征,在反黑实践中要加大打击政治保护伞的力度。现阶段境外黑社会组织对广东的渗透具有很强的侵财性和暴力性,或自设炉灶,或勾结境内不法分子和犯罪团伙,形成一股罪恶地下势力,对渗透地社会秩序、人民生命财产安全有着极大的危害。 相似文献

A 34‐year‐old man with manic‐depressive disorder was found dead sitting in a vehicle with a hose running from the exhaust pipe to the cabin. Numerous suicide notes were found inside his house. At autopsy, the decedent was wearing jeans and a long‐sleeved windcheater. Upon removal of his clothes, a series of messages were also found written on the legs and forearm. Death was due to carbon monoxide toxicity with a blood level of carboxyhemoglobin of 84%. Skin messages represent a rare form of suicide note that may suggest that a suicide has not been planned, as the decedent may have used the nearest surface to write on. This case demonstrates, however, that skin messages may be more organized, being written prior to dressing and setting up the fatal episode. They also may compliment other notes and messages. 相似文献
