Does multiple office-holding generate an electoral bonus? Evidence from Belgian national and local elections

Traditionally, scholars have assumed that multiple office-holding (i.e. the combination of a local and national directly elected political mandate) leads to an enhanced electoral performance. Although the prospect of electoral benefits for such a mandate combination seems plausible, it remains unclear whether accumulating a national and local mandate does indeed provide an additional boost compared to holding either one prior to the election. Previous studies have only offered limited support for this assumption. For instance, they have focused exclusively on French national elections. This article, however, scrutinises whether dual mandate-holding pays off individually, for the candidate, as well as collectively, for the list as a whole in both Belgian national and local elections. The results here strongly suggest that cumul des mandats does not yield an additional electoral reward compared to single office-holders, contradicting both theoretical presumptions and normative beliefs.     

Radiological, forensic, and anthropological studies of a concrete block containing bones

Multidisciplinary forensic, anthropological, and radiological studies of bone fragments encased in a concrete block were carried out to determine whether or not the bones were human. Multislice computed tomography (MSCT) investigation was performed before the bones were removed from the concrete. MSCT study pinpointed the location of the bone fragments within the concrete block, which was helpful for their extraction and recovery, and identified most of their types and nature. Osteological study on dry bones provided more accurate identification of the bones and of their side. According to both methods, the human skeletal remains were compatible with those of a child, aged 8-13 years old, with a minimum height of 128 cm. Neither investigation identified sex or racial phenotype. Both studies identified the skeletal remains as consisting of two animal and five human bones. Furthermore, both methods revealed that the concrete completely encased bones, suggesting a secondary burial.     

Study of the correlation between psychiatric and psychological diagnoses in sample offenders

This study deals with the frequency with which expert psychiatrists and psychologists make structural or nosographic diagnoses within the context of expert assessment.Thus, the rates of concordance between psychiatrists and psychologists in both types of diagnoses will be assessed.To do so, the level of inter-observer agreement on diagnoses between 1990 and 2003 was studied retrospectively in France through psychiatric and psychological assessments of 505 male offenders. The assessment of the correlation rates was carried out using the Kappa coefficient.The results show a range of 0.55 to 0.71 in inter-observer (psychiatrists vs psychologists) agreement for structural diagnoses, and 0.51 to 0.89 for nosographic diagnoses.In addition, a marked correlation between psychiatrists and psychologists may be noted regarding abstention in both structural (k = 66) and nosographic (k = 73) diagnoses. In fact, recommendations are made for improvement in the consistency of offender assessment in the psycho-legal French context.     

Use of forensic investigations in anti-doping

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.     

The household effect on electoral participation. A contextual analysis of voter signatures from a French polling station (1982–2007)

We use electoral participation data coded from signature lists to show that patterns of voter turnout, be they related to average participation, versatility or precise moments of voting, are strongly related to what we call “electorate households”, i.e. groups of voters registered in the same polling station and living together. Each household tends to be homogeneous, at levels much higher than chance would explain, so that modelling individual participation without taking this household effect into account ignores much of what actually happens. The status in the household also plays an important role among individual factors of voter participation. Not only do people who live together often participate together, but the precise shape of their relationships influences their behaviour.     

Validation of Large White Pig as an animal model for the study of cannabinoids metabolism: application to the study of THC distribution in tissues

This study presents a new animal model, the Large White Pig, which was tested for studying cannabinoids metabolism. The first step has focused on determination of plasma kinetics after injection of Delta(9)-tetrahydrocannabinol (THC) at different dosages. Seven pigs received THC by intravenous injections (50, 100 or 200 microg/kg). Plasma samples were collected during 48 h. Determination of cannabinoids concentrations were performed by gas chromatography/mass spectrometry. Results showed that plasma kinetics were comparable to those reported in humans. Terminal half-life of elimination was 10.6 h and a volume of distribution of 32 l/kg was calculated. In a second step, this model was used to determine the kinetic profile of cannabinoids distribution in tissues. Eight Large White male pigs received an injection of THC (200 microg/kg). Two pigs were sacrificed 30 min after injection, two others after 2, 6 and 24 h. Different tissues were sampled: liver, kidney, heart, lung, spleen, muscle, fat, bile, blood, vitreous humor and several brain areas. The fastest THC elimination was noted in liver tissue, where it was completely eliminated in 6 h. THC concentrations decreased in brain tissue slower than in blood. The slowest THC elimination was observed for fat tissue, where the molecule was still present at significant concentrations 24 h later. After 30 min, THC concentration in different brain areas was highest in the cerebellum and lowest in the medulla oblongata. THC elimination kinetics noted in kidney, heart, spleen, muscle and lung were comparable with those observed in blood. 11-Hydroxy-THC was only found at high levels in liver. THC-COOH was less than 5 ng/g in most tissues, except in bile, where it increased for 24 h following THC injection. This study confirms, even after a unique administration, the prolonged retention of THC in brain and particularly in fat, which could be at the origin of different phenomena observed for heavy users such as prolonged detection of THC-COOH in urine or cannabis-related flashbacks. Moreover, these results support the interest for this animal model, which could be used in further studies of distribution of cannabinoids in tissues.
