The relative efficacy of different forms of knowledge of results for the learning of a new relative timing pattern

The goal of the present study was to determine the relative efficacy of verbal and auditory knowledge of results for promoting learning of a new constrained relative timing pattern. In a series of four experiments we compared the efficiency of verbal knowledge of results to that of auditory knowledge of results. The results of all four experiments revealed that verbal knowledge of result is a very effective source of information to promote learning of a new imposed relative timing pattern. Auditory knowledge of results favoured learning of a new relative timing pattern in a very limited set of circumstances. In the present study, this was only the case when movement velocity remained constant from one segment of the task to the next and if it resulted in an unfamiliar temporal pattern. The results of all four experiments also provided evidence that movement parameterization and relative timing are independent processes that can be developed in parallel.     

Group identity and peer relations: A longitudinal study of group identity,perceived peer acceptance,and friendships amongst ethnic minority English children

This research examined whether peer relationships amongst ethnic minority status children reflect the social groups to which children belong and the degree to which they identify with these groups. A longitudinal study was conducted to investigate the influence of group identities (i.e., ethnic and national) on children's perceived peer acceptance and preference for same‐ethnic friendships. Measures of ethnic and English identification, perceived peer acceptance, and friendship choice were administered to 207 south‐Asian English children, aged between 5 and 11, at two time points 6 months apart. In line with predictions, longitudinal analysis showed that bicultural identification (i.e., higher ethnic and English identity) was related to higher perceived peer acceptance and less preference for same‐ethnic friendships. Importantly, as hypothesized, this finding was limited to the older children with more advanced social‐cognitive abilities. The results suggest that older children who adopted a bicultural identity were able to strategically ‘flag’ their multiple group identities, within their multicultural peer groups, to obtain acceptance amongst the maximum number of peers and show less preference for same‐ethnic friendships. This study extends previous peer relations research, which has typically focused on individual social deficits or classroom norms, by showing that group identities influence peer relationships amongst ethnic minority status children.     

Conflits et stratégies suscités par l'innovation

L'auteur examine les raisons des résistances induites par le changement technique en insistant sur la dévalorisation du statut des personnes touchées. Puis il présente la tentative de formalisation des organisations par l'informatique centralisée avant de montrer que l'acceptation de l'innovation passe par une négociation ménageant les objectifs défendus par les utilisateurs. Mais l'exécutant peut aussi s'approprier la technique et l'exploiter pour développer une stratégie de pouvoir. Des exemples sont pris dans des domaines variés: industrie, enseignement, administration, politique, agriculture, secteur médical.
This article examines the reasons of resistances caused by technical change with a special emphasis on status devaluation of persons concerned. The author continues with a discussion of management's attempt to control the work process in introducing centralized computer-based information systems, before arguing that innovation acceptance calls for a negotiation saving user's aims. But workers can also appropriate the technology and exploit it to develop a power strategy. Examples are chosen in a variety of sectors: industry, teaching, administration, politics, agriculture, medicine.     

Changing Rates of Suicide Ideation and Attempts Among Inuit Youth: A Gender‐Based Analysis of Risk and Protective Factors

Inuit in Canada currently suffer from one of the highest rates of suicide in the world. The objective of this study was to explore the prevalence of suicide ideations and attempts among 15–24 year olds living in Nunavik, Québec, and to explore risk and protective factors of suicide attempts as a function of gender. A cross‐sectional survey was conducted in 2004 across Nunavik. Univariate and multivariate logistic regressions were conducted. A total of 22% of young males and 39% of females adults reported past suicidal attempts. Gender differences were observed in relation to associated risk and protective factors as well as degree of exposure to risk factors. Suicide prevention must include alcohol and drug prevention programs and rehabilitation services, interventions to reduce physical and sexual violence and their long‐term impacts on Inuit youth, as well as exposure to culturally meaningful activities.
