Bulking Up (Identities): A Communication Framework for Male Fitness Identity     

Phillip E. Wagner 《Communication quarterly》2017,65(5):580-602

The goal of this interview study is to build upon a rich history of masculinities research, complicating the arenas in which masculinity is communicated, performed, negotiated, and enacted. Using Hecht’s communication theory of identity, analysis of this data reveals that men pursuing fitness find misalignment between the personal, relational, and enacted frames. Consequently, they engage in a host of discursive strategies to manage the uncertainty that is produced by these identity gaps. This study identifies three: excessive body discipline, forceful negotiation, and constant comparison. By exploring these gaps and strategies, this study aims to situate fitness as a space ripe for the production of identity work and as an intersectional identity element.  相似文献   

Changing personal epistemologies in early childhood pre-service teachers using an integrated teaching program   总被引：1，自引：0，他引：1

This study investigated changes in pre-service teachers' personal epistemologies as they engaged in an integrated teaching program. Personal epistemology refers to individual beliefs about the nature of knowing and knowledge and has been shown to influence teaching practice. An integrated approach to teaching, based on both an implicit and explicit focus on personal epistemology, was developed by an academic team within a Bachelor of Education (Early Childhood). The teaching program integrated content across four units of study, modelling personal epistemologies implicitly through collaborative reflexive practice. The students were also required to engage in explicit reflections on their personal epistemologies. Quantitative measures of personal epistemology were collected at the beginning and end of the semester using the Epistemological Beliefs Survey (EBS) to assess changes across the teaching period. Results indicated that pre-service teachers' epistemological beliefs about the integration of knowledge became more sophisticated over the course of the teaching period. Qualitative data included pre-service teachers' responses to open ended questions and field experience journal reflections about their perceptions of the teaching program and were collected at the end of the semester. These data showed that pre-service teachers held different conceptions about learning as integration, which provided a more nuanced understanding of the EBS data. Understanding pre-service teachers' epistemological beliefs provides promising directions for teacher preparation and professional enrichment.  相似文献   

The influence of hydration on anaerobic performance: a review     

Kraft JA  Green JM  Bishop PA  Richardson MT  Neggers YH  Leeper JD 《Research quarterly for exercise and sport》2012,83(2):282-292

This review examines the influence of dehydration on muscular strength and endurance and on single and repeated anaerobic sprint bouts. Describing hydration effects on anaerobic performance is difficult because various exercise modes are dominated by anaerobic energy pathways, but still contain inherent physiological differences. The critical level of water deficit (approximately 3-4%; mode dependent) affecting anaerobic performance is larger than the deficit (approximately 2%) impairing endurance performance. A critical performance-duration component (> 30 s) may also exist. Moderate dehydration (approximately 3% body weight; precise threshold depends on work/recovery ratio) impairs repeated anaerobic bouts, which place an increased demand on aerobic metabolism. Interactions between dehydration level, dehydration mode, testing mode, performance duration, and work/recovery ratio during repeated bouts make the dehydration threshold influencing anaerobic performance mode dependent.  相似文献

Abilities and skill acquisition: A latent growth curve approach     

Manuel C. Voelkle  Werner W. Wittmann  Phillip L. Ackerman 《Learning and individual differences》2006,16(4):303-319

The relationship between abilities and skill acquisition has been the subject of numerous controversies in psychology. However, while most researchers implicitly or explicitly accept the idea that abilities and skill acquisition should be related, empirical research has failed to provide evidence for a consistently strong correlation between the two constructs. Based on the reanalysis of a study on skill acquisition using the air traffic controller task TRACON [Ackerman, P. L., Kanfer, R., and Goff, M. (1995). Cognitive and Noncognitive Determinants and Consequences of Complex Skill Acquisition. Journal of Experimental Psychology. Applied, 1(4), 270–304], it will be shown how latent growth curve modeling can help to gain a better understanding of the relationship between human abilities and skill acquisition. A brief introduction into the basic concepts of latent growth curve modeling will be given, particularly with regard to the advantages for the analysis of skill acquisition and its determinants. The goal is thereby to provide evidence for a much closer association than commonly assumed and to offer a new, differential, perspective formerly obscured by traditional between-subject analyses.  相似文献
