The National Institute of Forensic Toxicology, Oslo, receives blood and urine samples from all Norwegian drivers apprehended on suspicion of driving under the influence of alcohol or drugs. In 1983 we received samples from 1446 drug-suspected drivers, out of which 445 underwent toxicological analysis. The drugs found most frequently were tetrahydrocannabinol (THC) (n = 199), diazepam (n = 166) and amphetamine (n = 102). A cautious interpretation of the data indicate that about 200 of the 445 subjects selected for toxicological analysis drove under severe influence of drugs. Because of the high percentage of submitted cases not analysed for drugs, this figure represents a minimum estimate. Compared with the results from 1978, we found a several-fold increase in detections of THC and amphetamine in 1983. The number of diazepam detections did not increase in a similar way, but we estimated that the diazepam detections would have increased 3-fold if we had analysed as frequent for this drug in 1983 as in 1978.  相似文献

A series of fatal motorcycle accidents from a 7-year period (1977-1983) has been analyzed. Of the fatalities 30 were operators of the motorcycle, 11 pillion passengers and 8 counterparts. Of 41 operators 37% were sober at the time of accident, 66% had measurable blood alcohol concentration (BAC); 59% above 0.08%. In all cases where a pillion passenger was killed, the operator of the motorcycle had a BAC greater than 0.08%. Of the killed counterparts 2 were non-intoxicated, 2 had a BAC greater than 0.08%, and 4 were not tested. The results advocate that the law should restrict alcohol consumption by pillion passengers as well as by the motorcycle operator. Suggestions made to extend the data base needed for developing appropriate alcohol countermeasures by collecting sociodemographic data on drivers killed or seriously injured should be supported.  相似文献

The aims of the authors in this paper has been to check the diagnostic ability of the Cathepsin A, B and D concentrations in the skin wound edges to the differential diagnosis between vital and postmortem wounds. We have studied 56 domestic pigs grouped in seven experimental series consisting of 8 animals in each, according to the time (0, 5, 15, 30 min and 1, 3 and 6 h) after the injury. The enzymatic activities were investigated following the methods by Bowen and Davison Biochem. J., 131 (1973) 417-419, Suhar and Marks J. Biochem., 101 (1979) 23-30 and by Anson (modified by Yamamoto, Eur. J. Biochem., 95 (1979) 459-467) for Cathepsin A, B and D, respectively. For the differential diagnosis between vital and postmortem wounds, our results showed that the most useful markers studied are the Cathepsin A and D activities, Cathepsin D that of the first one.  相似文献

The distance between politicians and those they are supposed to represent is substantial. Almost invariably, it is politicians themselves who are made to shoulder the responsibility for this ‘gap’, their actions being demonised. This paper assesses some ‘ordinary’ ethical lapses that politicians are often accused of: lying, breaking promises and being self-serving. It is argued that the public tend to apply double standards when it comes to the moral expectations that they have of their representatives, inasmuch as they far more readily accept ethically dubious actions when they apply to other social and public roles. The moral singularity of the political sphere is called into question, with the effect of helping to narrow the gap between the two categories, and encourage more empathy on the part of the public.  相似文献

ABSTRACT

The Dayton Peace Agreement ended the violence in Bosnia–Herzegovina, however, it also solidified antagonistic political identities leading to the creation of two social contracts: an ‘elite social contract’ involving primarily political elites of the main ethnic groups and an ‘everyday social contract’ involving ordinary citizens trying to manage a complex social and economic environment. The first social contract is hegemonic, however, alternative, non-nationalist views are slowly emerging. Grassroots groups, the surviving remnants of inter-ethnic coexistence, the integrating pull of market forces and the presence of a large diaspora all constitute resources for the creation of a resilient national social contract.  相似文献
