<正>在法医学亲子鉴定和个体识别中,Y染色体STR基因座(Y-STR)具有独特的优势,主要是由于其男性伴性遗传的特点[1-2]。在一些强奸案件的鉴定中,YSTR分型可以提供男性嫌疑人的遗传信息,并且基因分型结果不受女性成分的影响[3]。此外,Y-STR基因座缺乏重组,具有独特的单倍型特征,在了解人类群体特征和进化等方面具有重要的作用[4]。本研究拟调查获得中国辽宁汉族群体27个Y-STR基因座的遗  相似文献

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

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

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

审判过程并非仅仅是为了"查明真相"。自从美国的法律系统开始使用科学证人以来,法律领域就面临着混乱的局面。自从Frye规则到Daubert标准再到Kumho Tire标准,乃至发展为修改后的《联邦证据规则》702条,尽管法律系统经历了上述诸多努力,人们仍然不会相信法律系统能够从科学信息中获得预期的收益。科学主张和理论或真或假,它们的真或假是一个客观的问题。法律裁决可以断定法律真理为真,也可以断定"所谓的科学真理"为真。只有科学命题所描述的自然界现象和事件的性质——而非有关证据可靠性的法律裁决,也非法庭上的论证和交叉询问——能够证明真的科学命题为真,证明假的科学命题为假。  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

With increasing access to information and communication technologies such as the Internet, Ethiopia has recently taken responsive legislative measures. One such legislative measure is enactment of cybercrime rules as part of the Criminal Code of 2004. These rules penalize three items of computer crimes namely hacking, dissemination of malware and denial of service attacks. The cybercrime rules are however slightly outdated due to changes that have occurred in the field of cybercrime since the enactment of the Code. The surge of new varieties of cybercrimes previously uncovered under the Code and the need to legislate tailored evidentiary and procedural rules for investigation and prosecution of cybercrimes have recently prompted the Ethiopian government to draft modern and comprehensive cybercrime legislation, but the draft law still needs further work on cybercrimes in light of other major legislative developments at regional and national levels. This article closely examines major developments in cybercrime law and practice in Ethiopia since the enactment of the first set of cybercrime rules and proffers recommendations towards a unified cybercrime regime.  相似文献

This article considers sentencing in the Netherlands and in particular the changes that have been introduced since the 1980s, both in the adult and in the juvenile justice system. Several questions will be treated in the article. Sentencing in the Netherlands in the last two decades is analysed and some explanations for the changing trends are presented. Results indicate that the Netherlands is following a general pattern, prevalent in Europe and the US, of more punitive and repressive punishment. Also, the extent to which new sentencing options, such as community sanctions have made a difference to the upward trend in imprisonment, will be analysed. In an effort to reduce the costs of the system new policies are being developed, introducing both 'front door' and 'back door' varieties in sentencing. These will lead to some important and radical changes in the criminal justice system.  相似文献
