Mental toughness (MT) is considered a necessary ingredient for high-level performance. Unsurprisingly, scholarly interest in the development of mental toughness has increased over the past decade, with much of this work informed by qualitative designs. No study to date has systematically reviewed and integrated this body of qualitative research on MT development. The primary purpose of this study was to create an integrated theoretical framework that incorporates extant MT development research in sport and performance settings. Three subsequent aims were to (a) systematically review and evaluate the qualitative literature regarding key developmental factors and processes for MT; (b) synthesise knowledge of key developmental factors and processes for MT; and (c) generate an integrated framework that can inform future research and advancement in theory with regard to MT development. Following a systematic search of online journals, search engines, and databases, 10 papers met the criteria for inclusion and were retained. These studies served as the primary data for meta-data, meta-method, and meta-theory analyses, which were integrated using a meta-synthesis approach. Four key themes were identified from the existing qualitative evidence: personal characteristics, interactions with environment, progressive development, and breadth of experience. These unique themes were integrated with existing theory to propose a bioecological model of MT development that encompasses interdependent interactions among the person, proximal processes, context, and time. We describe how this model can be used as a heuristic for research and practice, and underscore the importance of methodological diversity for future work on the development of MT. 相似文献

Controversy continues whether curveballs are stressful for young baseball pitchers. Furthermore, it is unproven whether professional baseball pitchers have fewer kinematic differences between fastballs and off-speed pitches than lower level pitchers. Kinematic and kinetic data were measured for 111 healthy baseball pitchers (26 youth, 21 high school, 20 collegiate, 26 minor league, and 18 major league level) throwing fastballs, curveballs, and change-ups in an indoor biomechanics laboratory with a high-speed, automated digitising system. Differences between pitch types and between competition levels were analysed with repeated measures ANOVA. Shoulder and elbow kinetics were greater in fastballs than in change-ups, while curveball kinetics were not different from the other two types of pitches. Kinematic angles at the instant of ball release varied between pitch types, while kinematic angles at the instant of lead foot contact varied between competition levels. There were no significant interactions between pitch type and competition level, meaning that kinetic and kinematic differences between pitch types did not vary by competition level. Like previous investigations, this study did not support the theory that curveballs are relatively more stressful for young pitchers. Although pitchers desire consistent kinematics, there were differences between pitch types, independent of competition level. 相似文献

In this article Grande argues that American Indian intellectualism and its central concerns - sovereignty and self-determination - have been ignored, obscured, and impeded by dominant modes of educational theory. More specifically, she argues that current obsessions with identity theory and formation work to deny the critical difference of American Indians as tribal peoples of distinct nations with sovereign status and treaty rights. Dominant modes of identity theory, thus, work to obscure the real sources of oppression of Indigenous peoples, substituting radical social transformation with a politics of representation. In working to address the inner contradictions between dominant modes of identity theory and American Indian tribal subjectivity, Grande employs the use of narrative, examining the text of her own identity formation through the lenses of differing modes of identity theory, namely essentialist, postmodern, and critical identity theories. She analyzes the potential of each theory to produce transformative knowledge and inform the discourse on American Indian identity and intellectualism. The author ends with a discussion of the need for a critical Indigenous theory of tribal identity and liberation, for a collectivity of critique that ultimately forms the foundation for a new Red Pedagogy. 相似文献

This paper addresses the perceived consequences of the Chilean national teacher evaluation system. We interviewed 57 school leaders in 30 schools across 10 municipalities about effects and uses of the assessment in their schools. Results show that in the large majority of schools our interviewees observe positive effects such as increased teamwork and internal reflection processes based on the assessment results. Reports about effects at teacher level far outnumber institutional effects, and are mixed. In all schools our interviewees report on teachers’ negative emotions and work overload due to the assessment process, but also about their internalization of the underlying professional standards. The paper analyzes differences among schools and offers suggestions for the development of large-scale standardized teacher evaluation systems. 相似文献
