Democratic deliberation is an aspiration that, in the most favorable conditions, remains difficult to achieve. In divided or multinational societies, the requirements of democratic theory appear particularly daunting. This essay surveys the Canadian debate about democratization and constitutional politics to better understand the significance of democratic deliberation in a concrete case, when principles are evoked in a context where institutions, interests, identities and power also matter. The article proposes to think of deliberation and power politics as closely intertwined and, in fact impossible to separate. Even in the best conditions, multinational deliberations always remain imperfect exercises in practical reason.

The history of Alberta's meatpacking workers is closely connected with the broader historical struggles of the working class in North America. Like their counterparts from the packinghouses in Toronto and Montreal, the workers of Calgary and Edmonton organized and fought for union recognition between 1911 and 1920, thus joining a labour revolt that was spreading throughout Europe and North America in the wake of World War I and the October Revolution. They faced stiff resistance.

À travers l'analyse du conflit étudiant du printemps 2012 au Québec, nous montrons comment les mouvements sociaux peuvent changer, temporairement, le politique. Le politique est entendu ici comme l'ensemble des règles et pratiques individuelles et collectives qui régissent les relations entre les acteurs à propos du gouvernement de la communauté. Plus précisément, nous montrons que le mouvement de contestation a transformé le politique de trois manières. Premièrement, les six mois du conflit étudiant ont créé un nouveau clivage autour duquel la vie politique s'est réorganisée. Deuxièmement, les acteurs partisans et les associations étudiantes ont modifié leurs pratiques et actions quotidiennes, redéfinissant leur mode de relations et leur politique d'alliance. Troisièmement, l'expérience prolongée de la mobilisation a changé le rapport au politique pour les individus mobilisés en bousculant les articulations usuelles entre l'usage de la politique institutionnelle et celui de la politique protestataire.

La scoliose idiopathique est une déformation tridimensionnelle de la colonne vertébrale dont la pathogenèse reste obscure. Cette maladie affecte 2-4% des adolescents de 10-18 ans parmi les garçons et les filles. Il est à noter que les filles sont plus sévèrement affectées et ce en plus grand nombre que les garçons. Les études de jumeaux ont montré que les facteurs génétiques jouent un rôle important dans la scoliose idiopathique de l'adolescent (SIA). Depuis 2010, les études d'association pan génomiques ont été multipliées dans les recherches, visant à trouver des gènes candidats impliqués dans la SIA à travers des examens des polymorphismes nucléotidiques (SNPs). Un test génétique nommé "ScoliScore" a été publié pour essayer de prédire la progression de courbure dans la population caucasienne. Cependant, l'association n'a pas été reproduite dans une grande étude japonaise, soulignant l'importance d'une étude de réplication dans une population caucasienne indépendante. Dans ce contexte, mon projet de maîtrise a permis de génotyper plus de 1,4 millions de SNPs dans une cohorte canadienne-française dans le but: 1) de valider l'association de ScoliScoreTM; et 2) d’identifier les variants génomiques associées à la SIA dans la population québécoise. Notre étude a montré qu’aucun des variants constituant le test ScoliScoreTM n’était associé à la SIA. Ceci suggère que l'absence d'association dans une cohorte japonaise n'est pas due à l'appartenance ethnique. Aussi, nous avons identifié des variants génomiques associés significativement à l’initiation et/ou la progression de SIA dans la population québécoise, suggérant des gènes candidats impliqués dans la pathogenèse de SIA.

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.

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.

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.

L'oxygénothérapie hyperbare (OTH) consiste à soumettre un patient à des taux de pression plus élevés que la pression atmosphérique normale et de lui faire respirer 100 % d'oxygène. Cette approche a été mise à l'essai pour le traitement de nombreuses conditions médicales avec succès dans certains cas alors pour d'autres sa validité reste encore à démontrer. Dans le cas de la paralysie cérébrale son utilisation a soulevé de nombreuses controverses et les études conduites jusqu'alors n'ont pas encore convaincu tous les membres de la communauté scientifique et ce, malgré certains effets positifs mis en évidence. Une récente étude qui a montré des améliorations notables chez des enfants atteints de paralysie cérébrale (PC) traités avec de l'air légèrement pressurisé, de même que chez ceux traités avec un protocole standard pour l'oxygénothérapie hyperbare (l'OTH), est invoquée pour nier l'efficacité de l'OTH. Des considérations politiques et économiques, plutôt que purement scientifiques, jouent un rôle important dans cette controverse. Des recherches systématiques supplémentaires sont requises, mais entre-temps, comme les effets thérapeutiques de cette approche semblent plus importants que ceux des thérapies actuellement acceptées dans le traitement de la paralysie cérébrale, les enfants atteints de cette condition ne devraient pas se faire refuser l'accès à l'OTH.

This paper is an attempt to analyze bonds and their relevance within the confines of economics. They are discussed as both exogenous and endogenous variables. More specifically, the bonds of democratic politics are compared with those of non-democratic politics. It is argued that only those societies that have at their disposition certain kinds of bonds will be able to sustain democracy. It is further argued that the differential effects of democratic vs. non-democratic regimes on the respective bonds are rather weak. But then again, different kinds of democratic institutions might well have an effect on the prevalent bonds found in a society.

In 'Privacy and Politics', Kieron O'Hara discusses the relation of the political philosophy of privacy to technical aspects in Web development. Despite a vigorous debate, the concept remains ambiguous, and a series of types of privacy is defined: epistemological, spatial, ideological, decisional and economic. Each of these has a different meaning in the online environment, and will be defended by different measures. The question of whether privacy is a right is raised, and generational differences in attitude discussed, alongside the issue of whether privacy should be protected in advance, via a consent model, or retrospectively via increased transparency and accountability. Finally, reasons both theoretical and practical for ranking privacy below other values (such as security, efficiency or benefits for the wider community) are discussed.
