Investigation de liens de parenté à l'aide de l'ADN: lecture différentielle de rapports d'expertise

De nos jours, l'ADN apparaît fréquemment dans les affaires judiciaires et la littérature spécialisée. L'évaluation de ce type d'indice est vaste. En général, les débats restent toutefois assez théoriques. Dans la présente contribution, deux types courants d'analyse sont abordés, l'ADN nucléaire et l'ADN mitochondrial, dans le cadre d'une recherche en demi-fraternité. Deux rapports d'expertise seront décortiqués ligne par ligne pour en offrir une lecture critique et cerner la fiabilité et l'utilité des conclusions apportées par les experts.

Source inference of exogenous gamma-hydroxybutyric acid (GHB) administered to humans by means of carbon isotopic ratio analysis: novel perspectives regarding forensic investigation and intelligence issues.

γ-Hydroxybutyric acid (GHB) is an endogenous short-chain fatty acid popular as a recreational drug due to sedative and euphoric effects, but also often implicated in drug-facilitated sexual assaults owing to disinhibition and amnesic properties. Whilst discrimination between endogenous and exogenous GHB as required in intoxication cases may be achieved by the determination of the carbon isotope content, such information has not yet been exploited to answer source inference questions of forensic investigation and intelligence interests. However, potential isotopic fractionation effects occurring through the whole metabolism of GHB may be a major concern in this regard. Thus, urine specimens from six healthy male volunteers who ingested prescription GHB sodium salt, marketed as Xyrem(®), were analysed by means of gas chromatography/combustion/isotope ratio mass spectrometry to assess this particular topic. A very narrow range of δ(13)C values, spreading from -24.810/00 to -25.060/00, was observed, whilst mean δ(13)C value of Xyrem(®) corresponded to -24.990/00. Since urine samples and prescription drug could not be distinguished by means of statistical analysis, carbon isotopic effects and subsequent influence on δ(13)C values through GHB metabolism as a whole could be ruled out. Thus, a link between GHB as a raw matrix and found in a biological fluid may be established, bringing relevant information regarding source inference evaluation. Therefore, this study supports a diversified scope of exploitation for stable isotopes characterized in biological matrices from investigations on intoxication cases to drug intelligence programmes.

Organização Criminosa e Actividade Criminal: Implicações da Estruturação do Gangue

A investigação acerca dos gangues, da sua organização e da sua influência no comportamento dos seus membros tem vindo a aumentar ao longo dos últimos anos. Contudo, a maioria dos estudos centra-se nos factores que levaram os indivíduos a integrarem um gangue, limitando assim a nossa compreensão acerca desta matéria. Com esta finalidade, foram realizadas entrevistas semi-estruturadas a 47 elementos de gangues, abordando não só as suas histórias de vida, mas também a relação entre a estrutura e organização do gangue e variáveis comportamentais como o envolvimento em crimes violentos, venda de drogas, vitimização e auto-controle. Os resultados demonstram a existência de diferenças claras entre membros de gangues organizados e membros de gangues desorganizados, no que concerne aos seus crimes cometidos, a venda de drogas, e à vitimização a que estão sujeitos. Verifica-se ainda que membros de gangues organizados procuram mais o risco e evidenciam menos respeito pelas outras pessoas. Em suma, mesmo baixos níveis de organização do gangue são relevantes para o comportamento dos indivíduos que os integram, sendo que uma maior organização do gangue está relacionada com um aumento significativo de ofensas e de vitimização.

An investigation of the relationship between job characteristics and the gender wage gap

This paper re-examines gender wage differences, taking into account notonly worker characteristics but also job characteristics. Considerationof a wide set of job quality indicators can explain a fraction of thewage gap that would otherwise be attributed to pure wage discrimination.In any case, the fraction of the wage gap that remains associated todifferential rewards for identical factors across sexes is stillsubstantial. Our results suggest that in order to avoid overestimationof the fraction of the wage gap attributable to discrimination, it isnecessary to control for job characteristics.
