Drugs, alcohol, and criminal behaviour : a profile of inmates in canadian federal institutions

The scientific literature often mentions that there is a statistical connection between alcohol and drug consumption and criminal behaviour. However, there is little information available which would make it possible to quantify this connection, and specify the impact that drugs and alcohol have on criminal behaviour. Consumption of psychoactive substances has two major effects: intoxication and addiction. These effects are related, respectively, to the psycho-pharmacological and economic-compulsive models of the connection between drugs and crime. The first model associates drug use and intoxication with a decrease in cognitive functions and a lack of self-control, leading to aggressive impulses, violence and lack of inhibitions. The second model refers to the huge costs that are associated with being addicted to certain drugs. A person addicted to these drugs would need to engage in lucrative criminal activities in order to pay for them. This article explores and attempts to further define the links between alcohol, illicit drugs and criminal behaviour, taking into account the types of drugs consumed and the types of criminal behaviour displayed.

Comorbid Depression Among Untreated Illicit Opiate Users : Results From a Multisite Canadian Study

This study aimed to describe patterns of major depression (MDD) in a cohort of untreated illicit opiate users recruited from 5 Canadian urban centres, identify sociodemographic characteristics of opiate users that predict MDD, and determine whether opiate users suffering from depression exhibit different drug use patterns than do participants without depression. Baseline data were collected from 679 untreated opiate users in Vancouver, Edmonton, Toronto, Montreal, and Quebec City. Using the Composite International Diagnostic Interview Short Form for Major Depression, we assessed sociodemographics, drug use, health status, health service use, and depression. We examined depression rates across study sites; logistic regression analyses predicted MDD from demographic information and city. Chi-square analyses were used to compare injection drug use and cocaine or crack use among participants with and without depression. Almost one-half (49.3%) of the sample met the cut-off score for MDD. Being female, white, and living outside Vancouver independently predicted MDD. Opiate users suffering from depression were more likely than users without depression to share injection equipment and paraphernalia and were also more likely to use cocaine (Ps < 0.05). Comorbid depression is common among untreated opiate users across Canada; targeted interventions are needed for this population.

La communauté du dehors : imaginaire social et représentations du crime au Québec (XIXe-XXe siècle)

La société québécoise a, comme toutes les sociétés, ses crimes et criminels légendaires. Or, si ces faits divers célèbres ont fait l’objet, dans les dernières décennies, de quelques reconstitutions historiographiques, on connaît beaucoup moins, en revanche, le mécanisme de leur légendarisation, le processus historique et culturel par lequel ils passent du « fait divers » au fait mémorable. C’est d’abord ce processus que s’attache à étudier cette thèse de doctorat, qui porte sur quatre crimes célèbres des XVIIIe et XIXe siècles (le meurtre du seigneur de Kamouraska [1839] ainsi que les crimes commis par « la Corriveau » [1763], par le « docteur l’Indienne » [1829] et par les « brigands du Cap-Rouge » [1834-1835]) : pour chacun de ces cas particuliers, l’analyse reconstitue la généalogie des représentations du crime et du criminel de manière à retracer la fabrication et l’évolution d’une mémoire collective. Celles-ci font chaque fois intervenir un système complexe de discours : au croisement entre les textes de presse, les récits issus de la tradition orale et les textes littéraires, l’imaginaire social fabrique, à partir de faits criminels ordinaires, de grandes figures antagoniques, incarnations du mal ou avatars du diable. Ce vaste processus d’antagonisation est en fait largement tributaire d’une époque (le XIXe siècle) où, dans les sociétés occidentales, le « crime » se trouve soudainement placé au cœur de toutes les préoccupations sociales et politiques : l’époque invente un véritable engouement littéraire pour le crime de même que tout un arsenal de savoirs spécialisés, d’idées nouvelles et de technologies destinées à connaître, mesurer et enrayer la criminalité. Dès les premières décennies du XIXe siècle, le phénomène se propage de ce côté-ci de l’Atlantique. Dans la foulée, les grands criminels qui marquent la mémoire collective sont appelés à devenir des ennemis imaginaires particulièrement rassembleurs : figures d’une altérité radicale, ils en viennent à constituer le repoussoir contre lequel, à partir du XIXe siècle, s’est en partie instituée la société québécoise.

FosteraTM PRRS modified live vaccine efficacy against a Canadian heterologous virulent field strain of porcine reproductive and respiratory syndrome virus (PRRSV).

Vaccination is a useful option to control infection with porcine reproductive and respiratory syndrome virus (PRRSV), and several modified live-PRRSV vaccines have been developed. These vaccines have shown some efficacy in reducing the incidence and severity of clinical disease as well as the duration of viremia and virus shedding but have failed to provide sterilizing immunity. The efficacy of modified live-virus (MLV) vaccines is greater against a homologous strain compared with heterologous PRRSV strains. The objective of this study was to evaluate the efficacy of Fostera PRRS MLV vaccine in protecting against challenge with a heterologous field strain widely circulating in the swine herds of eastern Canada. Forty-six piglets were divided into 4 groups: nonvaccinated-nonchallenged; nonvaccinated-challenged; vaccinated-challenged; and vaccinated-nonchallenged. The animals were vaccinated at 23 d of age with Fostera PRRS and challenged 23 d later with a heterologous field strain of PRRSV (FMV12-1425619). Overall, the vaccine showed some beneficial effects in the challenged animals by reducing the severity of clinical signs and the viral load. A significant difference between nonvaccinated and vaccinated animals was detected for some parameters starting 11 to 13 d after challenge, which suggested that the cell-mediated immune response or other delayed responses could be more important than pre-existing PRRSV antibodies in vaccinated animals within the context of protection against heterologous strains.
