Validation of French and German versions of a Perceived Neighborhood Social Cohesion questionnaire among young Swiss males, and its relationship with substance use

This study main purpose was the validation of both French and German versions of a Perceived Neighborhood Social Cohesion Questionnaire. The sample group comprised 5065 Swiss men from the "Cohort Study on Substance Use Risk Factors." Multigroup Confirmatory factor analysis showed that a three-factor model fits the data well, which substantiates the generalizability of Perceived Neighborhood Social Cohesion Questionnaire factor structure, regardless of the language. The Perceived Neighborhood Social Cohesion Questionnaire demonstrated excellent homogeneity (α = 95) and split-half reliability (r = .96). The Perceived Neighborhood Social Cohesion Questionnaire was sensitive to community size and participants' financial situation, confirming that it also measures real social conditions. Finally, weak but frequent correlations between Perceived Neighborhood Social Cohesion Questionnaire and alcohol, cigarette, and cannabis dependence were measured.

E-cigarette use in young Swiss men : is vaping an effective way of reducing or quitting smoking ?

QUESTION UNDER STUDY: To test longitudinally differences in conventional cigarette use (cigarettes smoked, cessation, quit attempts) between vapers and nonvapers. METHODS: Fifteen months follow-up of a sample of 5 128 20-year-old Swiss men. The onset of conventional cigarette (CC) use among nonsmokers, and smoking cessation, quit attempts, changes in the number of CCs smoked among smokers at baseline were compared between vapers and nonvapers at follow-up, adjusted for nicotine dependence. RESULTS: Among baseline nonsmokers, vapers were more likely to start smoking at follow-up than nonvapers (odds ratio [OR] 6.02, 95% confidence interval [CI] 2.81, 12.88 for becoming occasional smokers, and OR = 12.69, 95% CI 4.00, 40.28 for becoming daily smokers). Vapers reported lower smoking cessation rates among occasional smokers at baseline (OR = 0.43 (0.19, 0.96); daily smokers: OR = 0.42 [0.15, 1.18]). Vapers compared with nonvapers were heavier CC users (62.53 vs 18.10 cigarettes per week, p <0.001) and had higher nicotine dependence levels (2.16 vs 0.75, p <0.001) at baseline. The number of CCs smoked increased between baseline and follow-up among occasional smokers (b = 6.06, 95% CI 4.44, 7.68) and decreased among daily smokers (b = -5.03, 95% CI -8.69, -1.38), but there were no differential changes between vapers and nonvapers. Vapers showed more quit attempts at follow-up compared with nonvapers for baseline occasional smokers (incidence rate ratio [IRR] 1.81, 95% CI 1.24, 2.64; daily smokers IRR 1.28, 95% CI 0.95, 1.73). CONCLUSIONS: We found no beneficial effects of vaping at follow-up for either smoking cessation or smoking reduction.

Les Science studies : de la marginalité thématique à la refondation de la discipline

Dans cet article, nous tentons de mettre en évidence ce qui, progressivement, constitue des points de convergence relativement partagés (l'analyse des controverses, l'attention portée au contenu, la prise en compte des connaissances, des inscriptions, des objets et des instruments dans l'action) qui influent partiellement sur les problématiques et approches d'autres domaines et courants de pensée en sociologie. Des déplacements significatifs ont été opérés qui sont potentiellement porteurs d'effets profonds, encore faudrait-il qu'ils soient repris par d'autres sociologues, ce qui n'a rien d'évident tant ils posent questions. Ainsi, les Science studies (étude sociale des sciences), qui ont longtemps constitué un domaine relativement à part de la sociologie du fait de ses objets d'études, contribue au renouveau des manières de penser et de travailler dans les sciences sociales en ouvrant des champs de questionnement autour de la définition des éléments constitutifs de la société et de l'agency. n this article, we highlight what gradually becomes converging topics and issues (analyzing of controversies, consideration for the content, the objects and the instruments of the action, integration of the issues related to the knowledge) and affects the problematics and approaches into other research fields and currents of thought in sociology. Significant shifts occurred which are potential carriers of profound effects if they would be picked up by other sociologists, which is not obvious due to the profounds debates emerging from theses studies. Thus, the Science Studies, which have long been an area relatively apart from sociology because of its objects of study, participate to the renewal of ways of thinking and working in the social sciences by opening questioning around the definition of the elements of society and the agency.
