Composantes culturelles du développement du raisonnement technique chez les enfants d'âge préscolaire lors de substitutions instrumentales

Cette recherche vise à définir le rôle du milieu culturel dans la substitution d'un outil par un autre instrument dans trois tâches techniques quotidiennes: découpage, dévissage, clouage. Trois catégories de sujets (n = 180) d'âge préscolaire (milieu: gitan, technicien, “favorisé”) ont été testées dans deux conditions expérimentales de substitution: (1) les sujets ont à choisir un instrument adéquat parmi les substituts (11 objets proposés) socialement marqués par leur usage courant; (2) les sujets sont invités à remplacer l'outil manquant par un objet non investi de significations sociales particulières. Les résultats montrent une supériorité générale du milieu gitan dans les deux conditions expérimentales; surtout dans la mesure où le substitut proposé ne se trouve pas investi par les valeurs culturelles propres au mode de vie du groupe social.     

Health Beliefs and Illness Perceptions as Related to Mammography Uptake in Randomly Selected Women in Greece

Previous research has shown that, although routine mammography screening can reduce mortality from breast cancer, the use of annual mammography screening remains well under 65%. In an effort to determine the factors that are associated with women’s mammography behaviors, this study used the health belief model and the common-sense model of self-regulation as the theoretical frameworks to explore health beliefs, illness representations, and women’s mammography practice. Data were obtained from a nationally representative sample of 408 Greek women, 40 years of age or older, with no personal history of cancer. Three dependent variables were considered: recent mammography, repeat mammography, and no mammogram during lifetime. Predictors included socio-demographic and medical variables, perceived benefits of mammography screening, perceived barriers to mammography screening, self-efficacy, as well as illness perceptions. Multivariate analyzes indicated that never having had a mammogram was more likely for women who perceived fewer benefits and more barriers to mammography screening, had more negative emotional representations of breast cancer, and had no private health insurance coverage. Factors associated with recent mammography were younger age, a good knowledge of the recommended mammography screening interval, a family history of breast cancer, and use of patient reminders for next mammogram. Adequate knowledge about the recommended mammography screening interval and higher values for breast cancer worry were associated with an increased number of repeat lifetime mammograms. Implications of the results and suggestions for future research are outlined.     

The Effectiveness of Teaching a Life Skills Program in a Sport Context

This research examined the role of attraction to one's team in predicting alcohol and marijuana use among intercollegiate athletes. Attraction to team and alcohol-related information were collected via an online survey and marijuana use-related information was gathered in a live setting. We investigated the influence of attraction to one's team above and beyond the influence of gender and perceived norms, and attraction to team as a moderator of these relationships. Attraction to one's team accounted for significant variance in marijuana use, and alcohol-related consequences after controlling for alcohol consumption. Regression analyses revealed significant interactions between gender, attraction to team, and norms in predicting alcohol and marijuana use. Stronger attraction to one's team may increase alcohol use but decrease marijuana use among male athletes, suggesting the importance of attraction to team when developing interventions for athletes.     

Innovation across cultures: Connecting leadership,identification, and creative behavior in organizations

Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.     

Regulatory foci and organizational commitment

We use regulatory focus theory to derive specific predictions regarding the differential relationships between regulatory focus and commitment. We estimated a structural equation model using a sample of 520 private and public sector employees and found in line with our hypotheses that (a) promotion focus related more strongly to affective commitment than prevention focus, (b) prevention focus related more strongly to continuance commitment than promotion focus, (c) promotion and prevention focus had equally strong effects on normative commitment. Implications of these findings for the three-component model of commitment, especially the ‘dual nature’ of normative commitment, as well as implications for human resources management and leadership are discussed.     

Youth sport motivational climate and attitudes toward migrants’ acculturation: The role of empathy and altruism

Previous research has shown that an empowering motivational climate in organized sport has been linked to attitudes favoring migrants’ integration. The purpose of the present study was to further test the relationship between motivational climate and acculturation attitudes, and to explore the role of prosocial skills as potential mediators of this relationship in adolescent athletes from the host population. Participants were 338 (13.61 ± .95 years of age) Greek adolescents (167 girls) participating in organized sport. Participants’ acculturation attitudes, prosocial skills, and perceptions of the coach-created motivational climate were measured. Analysis of structural models revealed that an empowering motivational climate was positively related with prosocial skills, reflecting empathy and altruism, which in turn were positively linked with acculturation attitudes favoring migrants’ integration. The results of the present study replicate previous findings regarding the links between empowering motivational climate and acculturation attitudes, and further, provide evidence that prosocial skills such as empathy and altruism mediate this relationship.     

The Relationships Between Athletes’ Perceptions of Coach-Created Motivational Climate,Self-Talk,and Self-Efficacy in Youth Soccer

The purpose of this study was to explore the mediating role of self-talk in the relationship between athletes’ perceptions of coach-created motivational climate and athletes’ self-efficacy. Two hundred eighty-nine youth soccer players (M = 11.63 years, SD = 1.55 years) completed the Automatic Self-Talk Questionnaire for Sport, the Empowering and Disempowering Motivational Climate Questionnaire, and a self-efficacy measure for soccer. The results showed that only positive and not negative self-talk mediated the relationship between empowering motivational climate and self-efficacy, whereas no relationship emerged between disempowering climate and self-efficacy, highlighting the role of self-talk explaining this relationship.     

Development and validation of the attention questionnaire of rehabilitated athletes returning to competition

The present study describes the development and validation of an instrument designed to examine athletes' selective attention returning to competition following a musculoskeletal injury--the attention questionnaire of rehabilitated athletes returning to competition (AQ-RARC). Using a sample of 186 rehabilitated athletes, exploratory factor analysis revealed a 10-item model that examines functional attention and distraction attention. Confirmatory factor analysis further supported the factorial validity of the AQ-RARC with another sample of 184 rehabilitated athletes. The two subscales have good internal consistency and test-retest reliability. The concurrent and discriminant validity of the new instrument were confirmed by examining correlations between the AQ-RARC with other constructs. It is concluded that the AQ-RARC is a valid and reliable instrument that can be used for clinical and research purposes.     

Towards Automating Decision Aiding Through Argumentation

Decision aiding can be abstractly described as the process of assisting a user/client/decision maker by recommending possible courses of his action. This process has to be able to cope with incomplete and/or inconsistent information and must adapt to the dynamics of the environment in which it is carried out. Indeed, on the one hand, complete information about the environment is almost impossible, and on the other hand, the information provided by the user is often affected by uncertainty; it may contains inconsistencies and may dynamically be revised because of various reasons. The aim of this paper is to present a model of the decision aiding process that is amenable to automation. The main features of the approach is that it models decision aiding as an iterative defeasible reasoning process, and it uses argumentation for capturing important aspects of the process. More specifically, argumentation is used for representing the relations between the cognitive artefacts that are involved in decision aiding, as well as for modelling the artefacts themselves. In modelling the cognitive artefacts, we make use of the notion of argument schemes and specify the related critical questions. More specifically, the work reported here aims at initiating a systematic study of the use of argumentation in future decision aiding tools. Our ambition is twofold: (i) enhance decision support capabilities of an analyst representing explicitly and accountably the reasons for which he recommend a solution for a decision maker and (ii) enhance decision support capabilities of an (semi) automatic device to handle (at least partially) the dialogue with the user.
