L’apport du capital social, familial, personnel et délinquant à l’explication de la relation entre alcool, drogues et violence chez les jeunes

Cette étude s’inscrit dans le cadre plus large des travaux menés par le groupe de recherche Drug, Alcool and Violence International (DAVI) qui cherche à préciser la nature des liens qui se tissent entre l’alcool, les drogues et la violence chez trois groupes de jeunes - étudiants, décrocheurs, contrevenants - des villes de Montréal, Toronto, Philadelphie et Amsterdam. Elle explore plus spécialement les dimensions du capital social, familial, individuel et délinquant comme étant des voies d’explication possibles de la relation constatée entre la consommation d’alcool et de drogues et la manifestation de gestes de violence chez les jeunes de la grande région montréalaise fréquentant le milieu scolaire secondaire. Trois objectifs spécifiques de recherche sont poursuivis soit : 1) déterminer, à travers une recension des écrits scientifiques, les modalités formant les dimensions du capital social, familial, individuel et délinquant; 2) cerner empiriquement dans les données, quelles sont les modalités à disposition permettant de rendre compte de la contribution du capital social, du capital familial, du capital individuel et du capital délinquant dans l’explication de la relation alcool/drogues et violence chez les jeunes; et 3) vérifier si les dimensions à l’étude influencent a) la consommation par les jeunes d’alcool et de drogues; b) la manifestation par eux de comportements délinquants, et plus spécialement de comportements violents, et c) la relation entre alcool, drogues et violence chez les jeunes fréquentant le milieu scolaire secondaire montréalais en fonction de ces dimensions. L’échantillon de type aléatoire est composé de 995 répondants (garçons et filles ) qui se répartissent dans huit écoles secondaires francophones et deux écoles secondaires anglophones provenant des secteurs public ou privé et de milieu favorisé ou défavorisé se trouvant sur les territoires des villes de Montréal, Laval et Longueuil constituant « la grande région de Montréal ». Les participants devaient répondre à un questionnaire composé de 138 questions dont la grande majorité sont fermées. Les données sociodémographiques caractérisant le jeune et son environnement, ses rapports avec sa famille, ses amis, l’école, son quartier, sa consommation d’alcool et de drogues, l’existence dans sa vie de comportements violents dont il aurait été auteur ou victime, la manifestation de gestes de délinquance ou de troubles de comportement sont les principales dimensions de la vie du jeune sondées par le questionnaire utilisé. D’entrée de jeu, spécifions que peu importe les substances consommées, très peu d’étudiants en font un usage problématique et que l’on ne note aucune propension à la délinquance chez la majorité des élèves de l’échantillon En somme, les analyses amènent à conclure à l’existence de relations statistiquement significatives entre la consommation d’alcool, de marijuana et de drogues dures et la propension à la délinquance et aux troubles de comportement, ces relations étant de force variable allant de modérée à forte. Toutefois, il faut bien noter que ces relations ne touchent qu’un petit nombre des élèves du secondaire participant à notre étude, comme ce fût le cas dans d’autres études. Plus spécifiquement, le capital familial paraît influencer seulement la consommation de marijuana. Ainsi, plus le degré de supervision parentale diminue, plus la fréquence de consommation de marijuana augmente. Le capital individuel produit un impact plus important sur la consommation d’alcool, de marijuana et de drogues dures, les troubles de comportement, et la propension à la délinquance. Ainsi, plus le capital individuel est affecté négativement, plus la consommation d’alcool, de marijuana et de drogues dures de même que la propension à la délinquance et aux troubles de comportement seront importants. Le capital social, quant à lui, explique davantage la consommation de marijuana que la consommation d’alcool et de drogues dures ou encore la manifestation de troubles de comportement et la propension à la délinquance. Finalement, le capital délinquant paraît influencer la consommation d’alcool, de marijuana et de drogues dures. Son influence se fait ressentir également, mais dans une moindre mesure, sur la manifestation de troubles de comportement et la propension à la délinquance. À notre grande surprise, la dimension du capital familial qui se révèle être particulièrement influente dans les écrits scientifiques ne ressort pas dans nos analyses comme nous l’avions envisagé. Nous attribuons cet état de fait aux limites imposées par l’utilisation d’une banque de données constituée initialement à d’autres fins que celles visées dans notre étude, et dans laquelle les facteurs reliés au capital familial, identifiés dans les écrits, n’étaient pas tous présents. Nul doute à que la consommation de substances psychoactives et la propension à la délinquance et aux troubles de comportement sont des comportements présents dans la population juvénile. Les modèles généralement utilisés pour expliquer les comportements déviants à l’étude ne produisent pas de résultats probants en ce qui concerne les écoliers, une population de jeunes d’ailleurs rarement étudiée à cet égard. Le modèle d’explication au cœur de nos analyses, mettant à contribution les dimensions du capital social, familial, individuel et délinquant, paraît prometteur surtout en ce qui concerne le capital délinquant, et ce, en dépit des limites imposées par la banque de données utilisée. À la lumière des résultats obtenus, il semble que l’explication de la cooccurrence de la consommation de substances psychoactives et de la propension à la délinquance et aux troubles de comportement soit multifactorielle. Les principaux facteurs contributifs sont ceux du capital délinquant pour la consommation d’alcool, de marijuana et de drogues dures de même que pour la propension à la délinquance alors les troubles de comportement se révèlent davantage expliqués par les facteurs composant le capital individuel. Nous estimons que la combinaison des dimensions du capital familial, individuel, social et individuel constitue une voie d’explication prometteuse de la relation alcool/drogue et violence chez les jeunes. Il nous apparaît dès lors qu’un instrument de collecte de données spécifiquement conçu pour en explorer le potentiel explicatif devrait être à la base de prochaines recherches en ce sens.

La ricerca e il gruppo esperienziale nell’ambito del progetto “www…parliamonepure.it” realizzato nel carcere di Castelvetrano (TP)

Nel panorama nazionale si discute poco degli autori dei reati sessuali, infatti l’attenzione dell’opinione pubblica e dei diversi attori sociali è più rivolta alle vittime dei reati sessuali. Ancora poco si affronta il problema legato al trattamento dei pedofili e dei violentatori di donne, nonostante l’argomento meriti approfondimenti anche in ambito penitenziario. Appare necessario ed opportuno individuare, nell’ambito del lavoro trattamentale, un modello operativo finalizzato alla ricerca di strategie che orientino il condannato per reati sessuali verso un percorso di analisi degli agiti. Ciò assume una rilevanza particolare nel trattamento dei detenuti sex offenders, pur riconoscendo la valenza del percorso trattamentale rivolto a qualsiasi tipologia di detenuti. L’esperienza realizzata presso la Casa Circondariale di Castelvetrano, descritta nel presente articolo, ha consentito, attraverso l’uso di una metodologia di lavoro di gruppo, di rilevare a carico dei soggetti partecipanti un quadro di consistente difficoltà nei percorsi di approfondimento e di analisi personale. In Italy, there has been little discussion about sex offenders. In fact, public and social actors’ attention has focused more on the victims of sex crimes rather than on criminals, so little importance is given to resocialization programs for paedophiles and rapists, even if this topic is worth exploring particularly in prisons. In the treatment phase, it is necessary and considered appropriate to identify an operational model aimed to orientate the sex offenders towards a process of analysis of their deviant behaviours. Through the methodology of the experiential group, the project carried out at Castelvetrano prison has highlighted the severe difficulties in personal analysis encountered by the sex offenders involved.

Matrimonio y vida cotidiana en el gravamen central costarricense (1851-1899)

ResumenEstudio basado en fuentes del Archivo de la Curia Metropolitana. Analiza la doctrina de la Iglesia Católica respecto al matrimonio, cómo son las relaciones matrimoniales en el gravamen central en la segunda mitad del S. XIX, los roles asignados al marido y a la mujer, así como las principales desviaciones: servicia, adulterio y problemas ocasionados por el alcoholismo.AbstractThis article is based on sources from the archives of the Catholic Church. It focuses on the doctrine of the Catholic Church regarding marriage, and on actual marital relations in the central graven of Costa Rica, during the second half of the nineteenth century, It also includes a discussion of the roles assigned to husband and wife, as well as the main deviant behaviours: extreme cruelty, adultery and problems caused by alcoholism.

Crystallisation behaviours of Al-based metallic glasses: Compositional and topological aspects

The different types of thermal crystallisation behaviours observed during continuous heating of M-based metallic glasses have been successfully associated with the topological instability. criterion, which is simply calculated from the alloy composition and metallic radii of the alloying elements and aluminium. In the present work, we report on new results evidencing the correlation between the values of X and the crystallisation behaviours in Al-based alloys of the Al-Ni-Ce system and we compare the glass-forming abilities of alloys designed with compositions corresponding to the same topological instability condition. The results are discussed in terms of compositional and topological aspects emphasizing the relevance of the different types of clusters in the amorphous phase in defining the stability of the glass and the types of thermal crystallisation.

Do simple prudent health behaviours protect men from myocardial infarction?

Background We tested whether behaviours such as discarding obvious fat on meat, cessation of smoking, avoidance of passive smoking, habitual use of reduced fat milk, prudent consumption of alcohol and regular but moderate physical exercise are associated with a reduction of cardiovascular risk. Methods This was a population-based case-control study done in Perth, Western Australia. The cases (n = 336) were men aged 27-64 years with a first-ever acute myocardial infarction (AMI) during the period 1992-1993, and who survived at least 28 days. The controls (n = 735) were participants in a population-based survey of cardiovascular risk factors conducted during May-November 1994. Both groups completed the same questionnaire and the data were analysed with multiple logistic regression using backward elimination technique. Results Among men aged 27-64 years simple measures such as participation in non-vigorous exercise (odds ratio [OR] = 0.5, 95% CI : 0.4-0.7), and avoidance of added salt (OR = 0.6, 95% CI : 0.4-0.9) are associated with significant and Important protection from AMI. Conclusion After 25 years of falling mortality in Australia, lifestyles can still be significantly improved to reduce heart disease even further.

Patterns of alcohol consumption in young Australian women: socio-demographic factors, health-related behaviours and physical health

Objective: To determine which sociodemographic factors. health-related behaviours and physical health conditions are associated with non-drinking, binge drinking and hazardous/harmful drinking in young Australian women. Methods: Cross-sectional data were obtained from the baseline survey of 14,762 young women (aged 18-23 years) enrolled in the Women's Health Australia study in 1996. Associations between a range of drinking patterns and sociodemographic factors, health-related behaviours and health conditions were examined. Results: Half the women were 'low intake' drinkers, a third 'rarely drank' and 9% were non-drinkers; however, 70% reported binge drinking with one-quarter of the binge drinkers doing so at least weekly. Nondrinkers were more likely than drinkers to be married, pregnant, non-smokers, born in non-English speaking countries, to live in the Northern Territory, and to have lower levels of education, employment, and private health insurance. Low intake/binge weekly' drinkers (12%) and 'hazardous/ harmful' drinkers (5%) were more likely than 'low risk' drinkers to be unmarried; to live in shared accommodation, alone or with their parents; to live in rural or remote areas; to have ever had any sexually transmitted infection; to be current smokers or ex-smokers and to have used unhealthy weight-control practices. Conclusions: The results confirm findings from other countries about the importance of social conditions as determinants of alcohol consumption by young women. Implications: Health promotion to reduce young women's alcohol consumption needs to be carefully targeted to take account of their demographies, living environments and beliefs.

Sexual behaviours and the risk of head and neck cancers: a pooled analysis in the International Head and Neck Cancer Epidemiology (INHANCE) consortium

Background Sexual contact may be the means by which head and neck cancer patients are exposed to human papillomavirus (HPV). Methods We undertook a pooled analysis of four population-based and four hospital-based case-control studies from the International Head and Neck Cancer Epidemiology (INHANCE) consortium, with participants from Argentina, Australia, Brazil, Canada, Cuba, India, Italy, Spain, Poland, Puerto Rico, Russia and the USA. The study included 5642 head and neck cancer cases and 6069 controls. We calculated odds ratios (ORs) of associations between cancer and specific sexual behaviours, including practice of oral sex, number of lifetime sexual partners and oral sex partners, age at sexual debut, a history of same-sex contact and a history of oral-anal contact. Findings were stratified by sex and disease subsite. Results Cancer of the oropharynx was associated with having a history of six or more lifetime sexual partners [OR = 1.25, 95% confidence interval (CI) 1.01, 1.54] and four or more lifetime oral sex partners (OR = 2.25, 95% CI 1.42, 3.58). Cancer of the tonsil was associated with four or more lifetime oral sex partners (OR = 3.36, 95 % CI 1.32, 8.53), and, among men, with ever having oral sex (OR = 1.59, 95% CI 1.09, 2.33) and with an earlier age at sexual debut (OR = 2.36, 95% CI 1.37, 5.05). Cancer of the base of the tongue was associated with ever having oral sex among women (OR = 4.32, 95% CI 1.06, 17.6), having two sexual partners in comparison with only one (OR = 2.02, 95% CI 1.19, 3.46) and, among men, with a history of same-sex sexual contact (OR = 8.89, 95% CI 2.14, 36.8). Conclusions Sexual behaviours are associated with cancer risk at the head and neck cancer subsites that have previously been associated with HPV infection.

Involvement of median raphe nucleus 5-HT1A receptors in the regulation of generalized anxiety-related defensive behaviours in rats

Changes in 5-HT1A receptor-mediated neurotransmission at the level of the median raphe nucleus (MRN) are reported to affect the expression of defensive responses that are associated with generalized anxiety disorder (e.g. inhibitory avoidance) but not with panic (e.g. escape). The objective of this study was to further explore the involvement of MRN 5-HT1A receptors in the regulation of generalized anxiety-related behaviours. Results of experiment 1 showed that intra-MRN injection of the 5-HT1A/7 receptor agonist 8-OH-DPAT (0.6 nmol) in male Wistar rats impaired the acquisition of inhibitory avoidance, without interfering with the performance of escape in the elevated T-maze test of anxiety. Pre-treatment with the 5-HT1A receptor antagonist WAY-100635 (0.18 nmol) fully blocked this anxiolytic-like effect. As revealed by experiment 2, intra-MRN injection of 8-OH-DPAT (0.6, 3 or 15 nmol) also caused anxiolytic effect in rats submitted to the light-dark transition test, another animal model that has been associated with generalized anxiety. In the same test, intra-MRN injection of WAY-100635 (0.18, 0.37 or 0.74 nmol) caused the opposite effect. Overall, the current findings support the view that MRN 5-HT neurons, through the regulation of 5-HT1A somatodendritic autoreceptors, are implicated in the regulation of generalized anxiety-associated behaviours.
