The fight against doping is mainly focused on direct detection, using analytical methods for the detection of doping agents in biological samples. However, the World Anti-Doping Code also defines doping as possession, administration or attempted administration of prohibited substances or methods, trafficking or attempted trafficking in any prohibited substance or methods. As these issues correspond to criminal investigation, a forensic approach can help assessing potential violation of these rules. In the context of a rowing competition, genetic analyses were conducted on biological samples collected in infusion apparatus, bags and tubing in order to obtain DNA profiles. As no database of athletes' DNA profiles was available, the use of information from the location detection as well as contextual information were key to determine a population of suspected athletes and to obtain reference DNA profiles for comparison. Analysis of samples from infusion systems provided 8 different DNA profiles. The comparison between these profiles and 8 reference profiles from suspected athletes could not be distinguished. This case-study is one of the first where a forensic approach was applied for anti-doping purposes. Based on this investigation, the International Rowing Federation authorities decided to ban not only the incriminated athletes, but also the coaches and officials for 2 years.  相似文献

Two complimentary studies were conducted to investigate the inter-rater reliability and performance of juvenile justice personnel when conducting the Structured Assessment of Violence Risk for Youth (SAVRY). Study 1 reports the performance on four standardized vignettes of 408 juvenile probation officers (JPOs) and social workers rating the SAVRY as part of their training. JPOs had high agreement with the expert consensus on the SAVRY rating of overall risk and total scores, but those trained by a peer master trainer outperformed those trained by an expert. Study 2 examined the field reliability of the SAVRY on 80 young offender cases rated by a JPO and a trained research assistant. In the field, intra-class correlation coefficients were 'excellent' for SAVRY total and most domain scores, and were 'good' for overall risk ratings. Results suggest that the SAVRY and structured professional judgment can be used reliably in the field by juvenile justice personnel and is comparable to reliability indices reported in more lab-like research studies; however, replication is essential.  相似文献

This essay is concerned with one key problem, namely, whether traditionalist conservatism (mainly in the British tradition) can be considered as an ideology. Some conservative theorists and commentators, have clearly been at pains to distance it from the ideological domain. They argue that conservatism is a natural disposition which embodies the historical tradition, customs and prejudices of a society and cannot, in consequence, be articulated as a body of ideas and values. In this sense, Conservatism cannot be considered to be an ideology like liberalism or socialism. Despite the attraction of such a claim for many of its proponents there are a number of fatal flaws. After unpacking the argument behind the claim the paper contends that the dispositional interpretation (which is a central plank of much traditionalist conservatism) remains inchoate and unsubstantiated.  相似文献

Reformulating the Commons   总被引:2,自引:0,他引:2  
The western hemisphere is richly endowed with a diversity of natural resource systems that are governed by complex local and national institutional arrangements that have not, until recently, been well understood. While many local communities that possess a high degree of autonomy to govern local resources have been highly successful over long periods of time, others fail to take action to prevent overuse and degradation of forests, inshore fisheries, and other natural resources. The conventional theory used to predict and explain how local users will relate to resources that they share makes a uniform prediction that users themselves will be unable to extricate themselves from the tragedy of the commons. Using this theoretical view of the world, there is no variance in the performance of self‐organized groups. In theory, there are no self‐organized groups. Empirical evidence tells us, however, that considerable variance in performance exists and many more local users self‐organize and are successful than is consistent with the conventional theory. Parts of a new theory are presented here.  相似文献
