Using football cultures as a vehicle to improve mental health in men: the case of the Redcar and cleveland boot room     

Kevin Dixon  Dave Belshaw  Paul Johnson  Darren Flynn 《Sport in Society》2019,22(7):1258-1274

This paper sets out to appraise (from the perspective of members) the impact of a localized, football-based mental health intervention. Commissioned in late 2015, the ‘Redcar and Cleveland Boot Room (BR)’ was implemented in response to mass redundancy in the local area, coupled with regional suicide rates in men that exceed the national average. Interactive discussions with BR members revealed that: (a) the language of football and shared identity were important for initiating and sustaining engagement in the BR; (b) peer-support and mentoring combined with member-led activities were active ingredients of the BR and (c) that the BR was an effective vehicle for building mental health resilience. This evaluation adds to the evidence base on the value of football as a context to engage adult males in community-based interventions targeting mental health resilience.  相似文献   

Kinematic and kinetic analysis of overhand,sidearm and underhand lacrosse shot techniques     

Charles A. J. Macaulay  Pro Stergiou  Darren Stefanyshyn  Luciano Tomaghelli 《Journal of sports sciences》2017,35(23):2350-2356

Lacrosse requires the coordinated performance of many complex skills. One of these skills is shooting on the opponents’ net using one of three techniques: overhand, sidearm or underhand. The purpose of this study was to (i) determine which technique generated the highest ball velocity and greatest shot accuracy and (ii) identify kinematic and kinetic variables that contribute to a high velocity and high accuracy shot. Twelve elite male lacrosse players participated in this study. Kinematic data were sampled at 250 Hz, while two-dimensional force plates collected ground reaction force data (1000 Hz). Statistical analysis showed significantly greater ball velocity for the sidearm technique than overhand (P < 0.001) and underhand (P < 0.001) techniques. No statistical difference was found for shot accuracy (P > 0.05). Kinematic and kinetic variables were not significantly correlated to shot accuracy or velocity across all shot types; however, when analysed independently, the lead foot horizontal impulse showed a negative correlation with underhand ball velocity (P = 0.042). This study identifies the technique with the highest ball velocity, defines kinematic and kinetic predictors related to ball velocity and provides information to coaches and athletes concerned with improving lacrosse shot performance.  相似文献   

The effects of mental fatigue on cricket-relevant performance among elite players     

Darren Veness  Stephen David Patterson  Owen Jeffries 《Journal of sports sciences》2017,35(24):2461-2467

This study investigated the effects of a mentally fatiguing test on physical tasks among elite cricketers. In a cross-over design, 10 elite male cricket players from a professional club performed a cricket run-two test, a Batak Lite reaction time test and a Yo-Yo-Intermittent Recovery Level 1 (Yo-Yo-IR1) test, providing a rating of perceived exertion (RPE) after completing a 30-min Stroop test (mental fatigue condition) or 30-min control condition. Perceived fatigue was assessed before and after the two conditions and motivation was measured before testing. There were post-treatment differences in the perception of mental fatigue (P < 0.001; d = ?7.82, 95% CIs = ?9.05–6.66; most likely). Cricket run-two (P = 0.002; d = ?0.51, 95% CIs = ?0.72–0.30; very likely), Yo-Yo-IR1 distance (P = 0.023; d = 0.39, 95% CIs = 0.14–0.64; likely) and RPE (P = 0.001; d = ?1.82, 95% CIs = ?2.49–1.14; most likely) were negatively affected by mental fatigue. The Batak Lite test was not affected (P = 0.137), yet a moderate (d = 0.41, 95% CIs = ?0.05–0.87) change was likely. Mental fatigue, induced by an app-based Stroop test, negatively affected cricket-relevant performance.  相似文献

Relationships between scores on Stanford-Binet IV and Wechsler preschool and primary scale of intelligence     

Howard Carvajal  Kathleen Hardy  Kathy L. Smith  Kenneth A. Weaver 《Psychology in the schools》1988,25(2):129-131

A kindergarten class of 9 boys and 11 girls took the 1986 Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Preschool and Primary Scale of Intelligence. Of 6 correlations of total scores and subtest pairs, only the correlation of total scores was statistically significant (p<.01).  相似文献

A “Deleterious” Driver: The “First Teacher” Reform in Sweden     

Ian Hardy  Karin Rönnerman 《Scandinavian Journal of Educational Research》2019,63(5):805-818

This article investigates the implementation of the “förstelärare” or “First teacher” reform in Sweden. We draw upon the insights of a superintendent, union official, principal, three First teachers, and two of their colleagues in one school, and recent literature on career development reform. We employ Michael Fullan’s overview of the “right” and “wrong” drivers of educational reform to analyse the extent to which the First Teacher initiative cultivated productive “professional capital.” The research reveals: how broader national policy aims were in clear tension with municipal-wide school development, and school-level development efforts; the perverse effects of a strong focus upon salary on professional conduct; and how an emphasis upon teachers’ roles per se undermined the espoused policy focus on enhancing teaching. The research cautions against the problematic effects of the initiative on more profession-oriented prerogatives, and how more external, “deleterious,” drivers of reform militate against more productive professional capital.  相似文献   

Governing teachers’ work and learning through data: Australian insights     

Ian Hardy 《Cambridge Journal of Education》2019,49(4):501-517

This article reveals the multiple ways in which data are constituted as a vehicle for governing teachers’ work and learning. Drawing on the concept of governance, including in relation to the sociology of numbers, and data from one school in Queensland, Australia, the research reveals how teachers’ work and learning were constituted through practices of: establishing specific ‘targets’, including various ‘audacious goals’ for school and national testing; focusing upon ‘aligning’ all forms of school, regional and national data collected within the school; and participating in various ‘data conversations’ about specific students with senior members of staff. While the research reveals how teachers found such practices beneficial for improving their practice with students, it also shows how this learning was always and everywhere framed within a broader discourse of data, and how this data-centric focus came to constitute what was valued about their work and learning, and that of their students.  相似文献
