ABSTRACT

The present study investigated athletes’ and coaches’ beliefs about the role of athletes’ entourage in deterring or promoting doping. Competitive athletes and coaches in Greece and Australia took part in semi-structured interviews. Our analysis of the interviews produced five main themes: coach influence, peer influence, doping stance, doping stigma, and entourage’s culture. Overall, coaches and peers having a close and trusty relationship with the athletes were considered most influential with respect to doping-related decisions. The majority of the athletes held a strong anti-doping stance but could not articulate why they held this position. This inability could be ascribed to the stigmatization of doping which led to lack of knowledge and anti-doping education. Finally, an anti-doping culture in the athletes’ environment was considered central to an anti-doping stance. The study findings provide valuable information towards a comprehensive understanding of the role athletes’ entourage can play in shaping athletes’ attitudes and decision for doping.  相似文献   

THE SYSTEM OF COORDINATES AS AN OBSTACLE IN UNDERSTANDING THE CONCEPT OF DIMENSION

The concept of dimension, one of the most fundamental ideas in mathematics, is firmly rooted in the basis of the school geometry in such a way that mathematics teachers rarely feel the need to mention anything about it. However, the concept of dimension is far from being fully understood by students, even at the college level. In this paper, we examine whether the Cartesian x-y plane is responsible for student difficulty in estimating the value of the dimension of an object, or is it only students misconceptions about dimension that lead them to a false estimation of the value of the dimension of various objects. A second question discussed in this paper examines whether the system of coordinates acts as an epistemological obstacle or whether it has only a didactical character.  相似文献   

The assessment of intrinsic and extrinsic motivation and amotivation: Validity and reliability of the Greek version of the Academic Motivation Scale

Self‐determination theory provides an integrated conception of school‐ and academic motivation. The theory proposes a continuum comprising three types of motivation: intrinsic motivation (IM), extrinsic motivation (EM), and amotivation (AM), characterised by seven dimensions (IM = to know, to accomplish and to experience stimulation, EM = external regulation, introjection and identification, and Amotivation). The purpose of the present study was to examine the psychometric properties of the Academic Motivation Scale (AMS) with Greek high school students. Two studies were conducted to examine the factorial, construct, concurrent and predictive validity of the scale along with its reliability properties. Confirmatory factor analyses supported the proposed seven‐factor structure. The scale showed satisfactory levels of internal consistency and temporal stability. Additionally, indices of the scale’s construct, concurrent, and predictive validity were in the desired direction. These findings support the use of the Greek version of the AMS for the assessment of intrinsic motivation, extrinsic motivation, and amotivation.  相似文献   

Cross-cultural generalizability of the theory of planned behavior among young people in a physical activity context

The present study tested the cross-cultural generalizability of the measurement and structural parameters of the theory of planned behavior (TPB) among youth in a physical activity context. Pupils from five cultural groups completed measures of attitudes, subjective norms, perceived behavioral control (PBC), and intentions for physical activity. Five weeks later, participants completed self-report measures of physical activity behavior. Confirmatory factor analyses and multisample structural equation models revealed well-fitting models within each sample with minimal variations in the measurement parameters across cultures. There were a few significant cross-cultural differences in the structural relations among the TPB constructs. Attitudes predicted intentions in all samples (beta range = .300 to .550), whereas the effect of the subjective norms on intention was nonsignificant in all but the Hungarian sample (beta = .243). Conversely, the effect of PBC on intentions was significant (beta range = .302 to .573) in all but the Hungarian sample. Findings support the generalizability of the measures and pattern of effects for the TPB among young people in a physical activity context.  相似文献
