Les gangs en Suisse : délinquance, victimisation et facteurs de risque

Abstract Gang membership constitutes one of the strongest risk factors of delinquency. Research on this topic found that gang members commit more offences in general and are particularly more prone to violent offences than other juveniles. Indeed, they are responsible for approximately 50 to 86% of the total offences perpetrated by juvenile offenders. In Switzerland, as in other European countries, there is a reluctance to use the term of gang to talk about delinquent youth groups. However, this term implies many stereotypes that do not apply to the majority of juvenile American gangs. Thus, it appears that some delinquent youth groups in European countries can be described as gangs. This manifestation of juvenile delinquency is increasingly studied by European researchers, whose studies demonstrate the high level of delinquency committed by gang members. This research assesses the proportion of gangs in Switzerland and their level of involvement in delinquency. Victimization of gang members as well as risk factors of gang membership are also analyzed. For this research, data of two self-reported juvenile delinquency surveys were used, namely the survey of "les jeunes et l'insécurité" and the second wave of the International Self-Reported Delinquency Survey (ISRD-2). The first survey took place in the canton of Vaud among 4'690 teenagers, and the second one was conducted across Switzerland by interviewing 3'648 teenagers aged 12 to 16. The results from the ISRD-2 survey show that 4.6% of young Swiss belong to a gang, whereas this is the case for 6.5% of teenagers in the canton of Vaud. About a third of the gang members ara girls. A strong link between the commission of offences and gang membership was found in both surveys. A teenager who does not belong to a gang commits on average 1.9 offences per year, whereas this number increases to 7.2 offences for teenagers who have delinquent peers and to 16 offences for gang members. The risk of victimization is also stronger for a gang member than for a non-gang member, as it is 4 to 5 times higher for assaults and robberies. International comparisons based on the ISRD-2 survey have been conducted, highlighting the high level of delinquency of gang members and their vulnerability to victimization. Risk factors of gang membership include the influence of accessibility to drugs in the neighbourhoods, the lack of self-control of the teenagers and their consumption of cannabis. Résumé Un des facteurs de risque les plus importants de la délinquance juvénile est l'appartenance à un gang. Les recherches faites sur cette problématique indiquent que les membres de gangs commettent plus de délits et des délits plus violents que les autres jeunes et qu'ils sont responsables d'environ 50 â 86% des actes délinquants perpétrés. En Suisse, tout comme dans d'autres pays européens, une réticence existe à utiliser le terme de gang pour parler des bandes de jeunes délinquants. Pourtant, ce terme implique de nombreux stéréotypes qui ne correspondent toutefois pas à la majorité des gangs américains. Ainsi, il apparaît que certaines bandes de jeunes délinquants présentes dans des pays européens peuvent être qualifiées de gangs. Cette manifestation de ta délinquance juvénile est de plus en plus étudiée par les chercheurs européens qui démontrent également la sur-criminalité de leurs membres. I La présente recherche évalue dans quelle proportion tes membres de gangs existent en Suisse et Quel est leur niveau d'implication dans la délinquance. Leur victimisation ainsi que les facteurs de risque de l'affiliation à de tels groupes y sont également analysés. Pour ce faire, les données de deux enquêtes ont été utilisées, à savoir l'enquête des jeunes et de l'insécurité portant sur 4'690 élèves de 8'? et 9*? année scolaire du canton de Vaud, ainsi que la deuxième vague du sondage de délinquance auto-reportée portant sur 3'648 jeunes suisses ayant entre 12 et 16 ans (ISRD-2 -International Self Reported Delinquency-). Ainsi, 4.6% des jeunes suisses, selon la recherche de l'ISRD-2, et 6.5% des jeunes vaudois, selon l'enquête des jeunes et de l'insécurité, appartiennent à un gang ; un tiers des membres étant de sexe féminin. Un lien fort entre la commission de délits et l'affiliation à un gang a été mis en évidence dans les deux enquêtes. Un adolescent qui ne fait pas partie d'un gang commet en moyenne 1.9 délits par année, un jeune qui a des pairs délinquants en commet en moyenne 7.2, alors que la moyenne annuelle des jeunes qui appartiennent à un gang s'élève à 16. Le risque de devenir victime est également plus important lorsqu'un jeune fait partie de tels groupes, puisqu'il est 4 à 5 fois plus élevé pour les agressions et les brigandages. Des comparaisons internationales, basées sur l'enquête de l'lSRD-2, ont pu être effectuées, mettant en exergue la sur-criminalité des membres de gangs ainsi que leur vulnérabilité face à la victimisation. Des facteurs de risque de l'affiliation è un gang, tels que l'influence de l'accessibilité à la drogue dans les quartiers où habitent les jeunes, le manque d'autocontrôlé de ces derniers ou leur consommation de cannabis ont été relevés

Editorial research and the publication process in biomedicine and health: Report from the Esteve Foundation Discussion Group, December 2012.

Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

The UniProt-GO Annotation database in 2011.

The GO annotation dataset provided by the UniProt Consortium (GOA: http://www.ebi.ac.uk/GOA) is a comprehensive set of evidenced-based associations between terms from the Gene Ontology resource and UniProtKB proteins. Currently supplying over 100 million annotations to 11 million proteins in more than 360,000 taxa, this resource has increased 2-fold over the last 2 years and has benefited from a wealth of checks to improve annotation correctness and consistency as well as now supplying a greater information content enabled by GO Consortium annotation format developments. Detailed, manual GO annotations obtained from the curation of peer-reviewed papers are directly contributed by all UniProt curators and supplemented with manual and electronic annotations from 36 model organism and domain-focused scientific resources. The inclusion of high-quality, automatic annotation predictions ensures the UniProt GO annotation dataset supplies functional information to a wide range of proteins, including those from poorly characterized, non-model organism species. UniProt GO annotations are freely available in a range of formats accessible by both file downloads and web-based views. In addition, the introduction of a new, normalized file format in 2010 has made for easier handling of the complete UniProt-GOA data set.

Religious beliefs in schizophrenia: Their relevance for adherence to treatment

The study examined how religious beliefs and practices impact upon medication and illness representations in chronic schizophrenia. One hundred three stabilized patients were included in Geneva's outpatient public psychiatric facility in Switzerland. Interviews were conducted to investigate spiritual and religious beliefs and religious practices and religious coping. Medication adherence was assessed through questions to patients and to their psychiatrists and by a systematic blood drug monitoring. Thirty-two percent of patients were partially or totally nonadherent to oral medication. Fifty-eight percent of patients were Christians, 2% Jewish, 3% Muslim, 4% Buddhist, 14% belonged to various minority or syncretic religious movements, and 19% had no religious affiliation. Two thirds of the total sample considered spirituality as very important or even essential in everyday life. Fifty-seven percent of patients had a representation of their illness directly influenced by their spiritual beliefs (positively in 31% and negatively in 26%). Religious representations of illness were prominent in nonadherent patients. Thirty-one percent of nonadherent patients and 27% of partially adherent patients underlined an incompatibility or contradiction between their religion and taking medication, versus 8% of adherent patients. Religion and spirituality contribute to shaping representations of disease and attitudes toward medical treatment in patients with schizophrenia. This dimension should be on the agenda of psychiatrists working with patients with schizophrenia.

Early tailored assertive community case management for hard-to-engage adolescents suffering from psychiatric disorders: an exploratory pilot study.

AIM: The study aims to evaluate the effects of assertive community treatment (ACT) on the mental health and overall functioning of adolescents suffering from severe psychiatric disorders and who refuse any traditional child psychiatric care. There are a few studies evaluating the effects of ACT on a population of adolescents with psychiatric disorders. This short report highlights the impact of an ACT programme tailored to the needs of these patients, not only as an alternative to hospitalization, but also as a new form of intervention for patients that are difficult to engage. METHODS: The effect of ACT on 35 adolescents using the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) as a measuring tool in pre- and post-intervention was evaluated. RESULTS: The results show that the intervention was associated with a significant improvement on the HoNOSCA overall score, with the following items showing significant amelioration: hyperactivity/focus problems, non-organic somatic symptoms, emotional symptoms, scholastic/language skills, peer relationships, family relationships and school attendance. CONCLUSION: ACT appears as a feasible intervention for hard-to-engage adolescents suffering from psychiatric disorders. The intervention seems to improve their mental health and functioning. This pilot study may serve as a basis to prepare a controlled study that will also take the costs of the intervention into account.

Transition to parenthood: The role of social interaction and endogenous networks

Empirical studies indicate that the transition to parenthood is influenced by an individual's peer group. To study the mechanisms creating interdepen- dencies across individuals' transition to parenthood and its timing we apply an agent-based simulation model. We build a one-sex model and provide agents with three different characteristics regarding age, intended education and parity. Agents endogenously form their network based on social closeness. Network members then may influence the agents' transition to higher parity levels. Our numerical simulations indicate that accounting for social inter- actions can explain the shift of first-birth probabilities in Austria over the period 1984 to 2004. Moreover, we apply our model to forecast age-specific fertility rates up to 2016.

A quasi-randomized group trial of a brief alcohol intervention on risky single occasion drinking among secondary school students.

OBJECTIVES: To show the effectiveness of a brief group alcohol intervention. Aims of the intervention were to reduce the frequency of heavy drinking occasions, maximum number of drinks on an occasion and overall weekly consumption. METHODS: A cluster quasi-randomized control trial (intervention n = 338; control n = 330) among 16- to 18-year-old secondary school students in the Swiss Canton of Zürich. Groups homogeneous for heavy drinking occasions (5+/4+ drinks for men/women) consisted of those having medium risk (3-4) or high risk (5+) occasions in the past 30 days. Groups of 8-10 individuals received two 45-min sessions based on motivational interviewing techniques. RESULTS: Borderline significant beneficial effects (p < 0.10) on heavy drinking occasions and alcohol volume were found 6 months later for the medium-risk group only, but not for the high-risk group. None of the effects remained significant after Bonferroni corrections. CONCLUSIONS: Group intervention was ineffective for all at-risk users. The heaviest drinkers may need more intensive treatment. Alternative explanations were iatrogenic effects among the heaviest drinkers, assessment reactivity, or reduction of social desirability bias at follow-up through peer feedback.

A test of Jessor's problem behavior theory in a Eurasian and a Western European developmental context.

PURPOSE: The current study tested the applicability of Jessor's problem behavior theory (PBT) in national probability samples from Georgia and Switzerland. Comparisons focused on (1) the applicability of the problem behavior syndrome (PBS) in both developmental contexts, and (2) on the applicability of employing a set of theory-driven risk and protective factors in the prediction of problem behaviors. METHODS: School-based questionnaire data were collected from n = 18,239 adolescents in Georgia (n = 9499) and Switzerland (n = 8740) following the same protocol. Participants rated five measures of problem behaviors (alcohol and drug use, problems because of alcohol and drug use, and deviance), three risk factors (future uncertainty, depression, and stress), and three protective factors (family, peer, and school attachment). Final study samples included n = 9043 Georgian youth (mean age = 15.57; 58.8% females) and n = 8348 Swiss youth (mean age = 17.95; 48.5% females). Data analyses were completed using structural equation modeling, path analyses, and post hoc z-tests for comparisons of regression coefficients. RESULTS: Findings indicated that the PBS replicated in both samples, and that theory-driven risk and protective factors accounted for 13% and 10% in Georgian and Swiss samples, respectively in the PBS, net the effects by demographic variables. Follow-up z-tests provided evidence of some differences in the magnitude, but not direction, in five of six individual paths by country. CONCLUSION: PBT and the PBS find empirical support in these Eurasian and Western European samples; thus, Jessor's theory holds value and promise in understanding the etiology of adolescent problem behaviors outside of the United States.

Predictors of onset of cannabis and other drug use in male young adults: results from a longitudinal study.

BACKGROUND: The use of cannabis and other illegal drugs is particularly prevalent in male young adults and is associated with severe health problems. This longitudinal study explored variables associated with the onset of cannabis use and the onset of illegal drug use other than cannabis separately in male young adults, including demographics, religion and religiosity, health, social context, substance use, and personality. Furthermore, we explored how far the gateway hypothesis and the common liability to addiction model are in line with the resulting prediction models. METHODS: The data were gathered within the Cohort Study on Substance Use Risk Factors (C-SURF). Young men aged around 20 years provided demographic, social, health, substance use, and personality-related data at baseline. Onset of cannabis and other drug use were assessed at 15-months follow-up. Samples of 2,774 and 4,254 individuals who indicated at baseline that they have not used cannabis and other drugs, respectively, in their life and who provided follow-up data were used for the prediction models. Hierarchical logistic stepwise regressions were conducted, in order to identify predictors of the late onset of cannabis and other drug use separately. RESULTS: Not providing for oneself, having siblings, depressiveness, parental divorce, lower parental knowledge of peers and the whereabouts, peer pressure, very low nicotine dependence, and sensation seeking were positively associated with the onset of cannabis use. Practising religion was negatively associated with the onset of cannabis use. Onset of drug use other than cannabis showed a positive association with depressiveness, antisocial personality disorder, lower parental knowledge of peers and the whereabouts, psychiatric problems of peers, problematic cannabis use, and sensation seeking. CONCLUSIONS: Consideration of the predictor variables identified within this study may help to identify young male adults for whom preventive measures for cannabis or other drug use are most appropriate. The results provide evidence for both the gateway hypothesis and the common liability to addiction model and point to further variables like depressiveness or practising of religion that might influence the onset of drug use.

Congenital disorder of glycosylation type Id (CDG Id) : phenotypic, biochemical and molecular characterization of a new patient

Rapport de synthèseLes troubles de la glycosylation (Congenital Disorders of Glycosylation, CDG) regroupent une famille de maladies multi-systémiques héréditaires causées par des défauts dans la synthèse de glycoconjugés. La glycosylation est une réaction enzymatique consistant à lier de façon covalente un glucide à une chaîne peptidique ou une protéine. Il existe deux types de glycosylation. La N-gjycosylation est l'addition de glucides aux chaînes peptidiques en croissance dès leur entrée dans la lumière du réticulum endoplasmique. Elle s'effectue sur les futures glycoprotéines membranaires et conduit à des chaînes de sucres courtes et ramifiées. La O-glycosylation est l'addition de glucides au niveau des résidus hydroxylés des acides aminés sérine et thréonine des chaînes peptidiques déjà présentes dans la lumière de l'appareil de Golgi. Elle est, dans la plupart des cas, effectuée sur îes protéoglycanes et conduit à des chaînes de sucres longues et non ramifiées. La classification des CDG repose sur le niveau de l'étape limitante de la glycosylation. Les CDG de type 1, plus fréquents, regroupent les déficits enzymatiques se situant en amont du transfert de Poligosaccharide sur la chaîne peptidique. Les CDG de type 2 regroupent ceux ayant lieu en aval de ce transfert. Parmi les nombreux différents sous-types de CDG, le CDG de type ld est causé par une anomalie de la mannosyltransferase, enzyme codée par le gène ALG3 (chromosome 3q27). Jusqu'à ce jour, six patients atteints de CDG ld ont été reportés dans la littérature. Notre travail a permis de décrire un septième patient et d'affiner les caractéristiques cliniques, biologiques, neuroradiologiques et moléculaires du CDG ld. Notre patient est notamment porteur d'une nouvelle mutation de type missense sur le gène ALG3. Tous les patients atteints de CDG ld présentent une encéphalopathie progressive avec microcéphalie, retard psychomoteur sévère et épilepsie. Une ostéopénie marquée est présente chez certains patients. Elle est parfois sous diagnostiquée et révélée uniquement lors de fracture pathologique. Les patients atteints de CDG ld présentent également des traits dysmorphiques typiques, mais aucune atteinte multi-systémique ou anomalie biologique spécifique n'est retrouvée telle que dans les autres types de CDG. Le dépistage biochimique des troubles de la glycosylation se fait par une analyse simple et peu coûteuse qui est l'analyse de la transferrine sérique par isoelectrofocusing ou par électrophorèse capillaire. Un tel dépistage devrait être effectué chez tout patient présentant une encéphalopathie d'origine indéterminée, et cela même en l'absence d'atteinte multi- systémique. Notre travail a été publié sous forme d'article de type « short report », peer-reviewed, dans le Journal of Inherited Metabolic Diseases. Le Journal est une révue spécialisée du domaine des erreirs innées du métabolisme. S'agissant d'un seul patient rapporté, l'article ne montre que très synthétiquement le travail effectué, Pour cette raison un complément à l'article avec matériel, méthodes et résultats figure ci-après et concerne la partie de recherche moléculaire de notre travail. La doctorante a non seulement encadré personnellement le patient au niveau clinique et biochimique, mais a plus particulièrement mis au point l'analyse moléculaire du gène ALG3 dans le laboratoire de Pédiatrie Moléculaire pour la première fois ; cela a impliqué l'étude du gène, le choix des oligonucleotides et l'optimisation des réactions d'amplification et séquençage.

Effects of communication training on real practice performance: a role-play module versus a standardized patient module.

This study investigated the effectiveness of modules involving standardized patients and role-plays on training communication skills. The first module involved standardized patients and an Objective Structured Clinical Examination (OSCE); the second module consisted of peer role-plays and a written examination. A randomized posttest-only control group design with first-year nursing students was used. The intervention group received one-to-one communication training with direct oral feedback from the standardized patient. The control group had training with peer role-playing and mutual feedback. The posttest involved students' rating their self-efficacy, and real patients and clinical supervisors evaluated their communication skills. No significant differences were found between self-efficacy and patient ratings. However, the clinical supervisors rated the intervention group's communication skills to be significantly (p < 0.0001) superior. Assessments by clinical supervisors indicate that communication training modules including standardized patients and an OSCE are superior to communication training modules with peer role-playing.

A systematic review of longitudinal population-based studies on the predictors of smoking cessation in adolescent and young adult smokers.

OBJECTIVE: To describe the determinants of self-initiated smoking cessation of duration of at least 6 months as identified in longitudinal population-based studies of adolescent and young adult smokers. METHODS: A systematic search of the PubMed and EMBASE databases using smoking, tobacco, cessation, quit and stop as keywords was performed. Limits included articles related to humans, in English, published between January 1984 and August 2010, and study population aged 10-29 years. A total of 4502 titles and 871 abstracts were reviewed independently by 2 and 3 reviewers, respectively. Nine articles were retained for data abstraction. Data on study location, timeframe, duration of follow-up, number of data collection points, sample size, age/grade of participants, number of quitters, smoking status at baseline, definition of cessation, covariates and analytic method were abstracted from each article. The number of studies that reported a statistically significant association between each determinant investigated and cessation were tabulated, from among all studies that assessed the determinant. RESULTS: Despite heterogeneity in methods across studies, five factors robustly predicted quitting across studies in which the factor was investigated: not having friends who smoke, not having intentions to smoke in the future, resisting peer pressure to smoke, being older at first use of cigarette and having negative beliefs about smoking. CONCLUSIONS: The literature on longitudinal predictors of cessation in adolescent and young adult smokers is not well developed. Cessation interventions for this population will remain less than optimally effective until there is a solid evidence base on which to develop interventions.

Cannabis Dependence in Swiss Adolescents Exploration of the Role of Anxiety, Coping Styles, and Psychosocial Difficulties

This naturalistic cross-sectional study explores how and to what extent cannabis dependence was associated with intrapersonal aspects (anxiety, coping styles) and interpersonal aspects of adolescent functioning (school status, family relationships, peer relationships, social life). A convenience sample of 110 adolescents (aged 12 to 19) was recruited and subdivided into two groups (38 with a cannabis dependence and 72 nondependent) according to DSM-IV-TR criteria for cannabis dependence. Participants completed the State-Trait Anxiety Inventory (STAI-Y), the Coping Across Situations Questionnaire (CASQ), and the Adolescent Drug Abuse Diagnosis (ADAD) interview investigating psychosocial and interpersonal problems in an adolescent's life. Factors associated with cannabis dependence were explored with logistic regression analyses. The results indicated that severity of problems in social life and peer relationships (OR = 1.68, 95% CI = 1.21 - 2.33) and avoidant coping (OR = 4.22, 95% CI = 1.01 - 17.73) were the only discriminatory factors for cannabis dependence. This model correctly classified 84.5% of the adolescents. These findings are partially consistent with the "self-medication hypothesis" and underlined the importance of peer relationships and dysfunctional coping strategies in cannabis dependence in adolescence. Limitations of the study and implications for clinical work with adolescents are discussed.

Leadership at the upper echelons : three essays

"IT'S THE ECONOMY STUPID", BUT CHARISMA MATTERS TOO: A DUAL PROCESS MODEL OF PRESIDENTIAL ELECTION OUTCOMES. ABSTRACT Because charisma is assumed to be an important determinant of effective leadership, the extent to which a presidential nominee is more charismatic than his opponent should be an important determinant of voter choices. We computed a composite measure of the rhetorical richness of acceptances speeches given by U.S. presidential candidates at their national party convention. We added this marker of charisma to Ray C. Fair's presidential vote-share equation (1978; 2009). We theorized that voters decide using psychological attribution (i.e., due to macroeconomics and incumbency) as well as inferential processes (i.e., due to leader charismatic behavior) when voting. Controlling for the macro-level variables and incumbency in the Fair model, our results indicated that difference between nominees' charisma is a significant determinant of electoral success, particularly in close elections. This extended model significantly improves the precision of the Fair model and correctly predicts 23 out of the last 24 U.S. presidential elections. Paper 2: IT CEO LEADERSHIP, CORPORATE SOCIAL AND FINANCIAL PERFORMANCE. ABSTRACT We investigated whether CEO leadership predicted corporate financial performance (CFP) and corporate social performance (CSP). Using longitudinal data on 258 CEOs from 117 firms across 19 countries and 10 industry sectors, we found that determinants of CEO leadership (i.e., implicit motives) significantly predicted both CFP and CSP. As expected, the most consistent positive predictor was Responsibility Disposition when interacting with n (need for) Power. n Achievement and n Affiliation were generally negatively related or unrelated to outcomes. CSP was positively related to accounting measures of CFP. Our findings suggest that executive leader characteristics have important consequences for corporate level outcomes. Paper 3. PUNISHING THE POWERFUL: ATTRIBUTIONS OF BLAME AND LEADERSHIP ABSTRACT We propose that individuals are more lenient in attributing blame to leaders than to nonleaders. We advance a motivational explanation building on the perspective of punishment and on system justification theory. We conducted two scenario experiments which supported our proposition. In study 1, wrongdoer leader status was negatively related to blame and the perceived seriousness of the wrongdoing. In study 2, controlling for the Big-Five personality factor and individual differences in moral evaluation (i.e., moral foundations), wrongdoer leader status was negatively related with desired severity of punishment, and fair punishments were perceived as more just for non-leaders than for leaders.
