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

In this paper, we present a computer-assisted method for facial reconstruction. This method provides an estimation of the facial shape associated with unidentified skeletal remains. Current computer-assisted methods using a statistical framework rely on a common set of extracted points located on the bone and soft-tissue surfaces. Most of the facial reconstruction methods then consist of predicting the position of the soft-tissue surface points, when the positions of the bone surface points are known. We propose to use Latent Root Regression for prediction. The results obtained are then compared to those given by Principal Components Analysis linear models. In conjunction, we have evaluated the influence of the number of skull landmarks used. Anatomical skull landmarks are completed iteratively by points located upon geodesics which link these anatomical landmarks, thus enabling us to artificially increase the number of skull points. Facial points are obtained using a mesh-matching algorithm between a common reference mesh and individual soft-tissue surface meshes. The proposed method is validated in term of accuracy, based on a leave-one-out cross-validation test applied to a homogeneous database. Accuracy measures are obtained by computing the distance between the original face surface and its reconstruction. Finally, these results are discussed referring to current computer-assisted reconstruction facial techniques. 相似文献

Lesions of the brain stem and cerebellum due to nutritional deficiencies are mostly seen in chronic alcohol abuse and more rarely in severe malnutrition. We report the case of a 27-year-old woman, found dead in the family flat. She presented cachexia (167 cm, 25 kg) and multiple hematomas of the limbs. Postmortem examination revealed lesions due to peritonitis. Neuropathological examination showed severe atrophy of the corpus callosum and central neuronal chromatolysis, which are observed in pellagra. Inflammatory colitis or celiac disease was not found. Toxicological analysis was negative, in particular no alcohol absorption. Pellagra, which is due to nicotinamide deficiency, is a disease rarely seen in this country. In this case, nutritional deficiency was the consequence of failure to eat in a context of abuse. The woman was born of an incestuous relationship and presented intellectual retardation due to poor affective relations with her mother. 相似文献

Public transportation policy is analyzed as the output of a complex social system of interdependencies and power relationships linking the central state bodies to various economic and political organizations. The interest groups structure the system by controlling the implementation process. The system works because of cheating—violating the public regulations, but the interest groups need state regulation to protect their privileges.The study of governmental projects is a particularly stimulating form of political analysis. Because it emphasizes both the process and the contents of the activities of public authorities, which is to say the goods and services produced by the State, such a study deals with problems having specific impact on and distinct meaning for individuals. It also allows one to avoid overly abstract speculation on the nature of the State by placing the discussion on a more scientifically fruitful level, that of the effective interactions and exchanges among institutions and groups.Our objective will be to demonstrate the importance of the implementation sequence of public policy, particularly in terms of its effects on the understanding of the definition of alternative solutions. We will concentrate on the way in which an ensemble of systems effects, induced by governmental action conditions both the perception of the problem to which this action is supposedly responding, and the elaboration of decisions to solve the problem. The method employed will be that of suggesting a form of analysis which will discern those fields of force and interaction processes with which decision makers, in this case public authorities, are confronted. The method employed should thus be useful in understanding the process of decision making. 相似文献
