Containment and denial: raising awareness of unconscious processes present when teachers are working with children and families where there is domestic abuse     

Gemma Ellis 《Educational Psychology in Practice》2018,34(4):412-429

This paper reports a small-scale, mixed methods research project exploring the perceptions and experiences of primary school teachers regarding domestic abuse. The paper focuses on the psychoanalytic concepts of containment and denial present in such situations. Questionnaire findings suggested that there was a significant difference between teachers who had attended relevant training and those who had not in their confidence levels in 1) responding to disclosures, and 2) recognising whether a child was exposed to domestic abuse (n = 165). Semi-structured interviews, analysed using thematic analysis, were carried out with experienced teachers (n = 8). Four overarching themes were identified: emotional factors of the teacher’s role; working within the school system; the relationship with the child and family; and uncertainty about what teachers need to know. Findings are discussed in relation to the psychoanalytic concepts of containment and denial. Implications for practice, identifying the roles of unconscious processes and holistic containment, are discussed.  相似文献

The association between fundamental athletic movements and physical fitness in elite junior Australian footballers     

Carl T. Woods  Ian McKeown  Justin Keogh  Sam Robertson 《Journal of sports sciences》2018,36(4):445-450

This study investigated the associations between fundamental athletic movement and physical fitness in junior Australian football (AF). Forty-four under 18 players performed a fundamental athletic movement assessment consisting of an overhead squat, double lunge, single leg Romanian deadlift and a push up. Movements were scored on three assessment criterions using a three-point scale. Additionally, participants performed five physical fitness tests commonly used for talent identification in AF. A Spearman’s nonparametric correlation matrix was built, with correlation coefficients being visualised using a circularly rendered correlogram. Score on the overhead squat was moderately positively associated with dynamic vertical jump height on left (r_s = 0.40; P ≤ 0.05) and right (r_s = 0.30; P ≤ 0.05) leg take-off, stationary vertical jump (r_s = 0.32; P ≤ 0.05) and negatively associated with 20-m sprint time (r_s = ?0.35; P ≤ 0.05). Score on the double lunge (left/right side) was moderately positively associated with the same physical fitness tests as well as score on the multistage fitness test. Results suggest that improvements in physical fitness qualities may occur through concurrent increases in fundamental athletic movement skill, namely the overhead squat and double lunge movements. These findings may assist with the identification and development of talent.  相似文献

Contraction force specificity and its relationship to functional performance     

Nigel Harris  John Cronin  Justin Keogh 《Journal of sports sciences》2013,31(2):201-212

Abstract

Best practice for improving strength and power through resistance strength training has been the subject of much research and subsequent conjecture. Much of the conjecture can be attributed to methodological discrepancies. The type of dynamometry used in testing, the training experience of research participants, the specific technique employed in a lift, and the methods of collection and calculation all impact on the final variables of interest. This review examines contraction force specificity by first addressing the methodological issues surrounding our interpretation of the results. Then we address the kinematics and kinetics associated with single and multiple repetitions in relation to the development of strength, power, and functional performance. This discussion provides the delimitations for analysis of subsequent training studies. Finally, recommendations are formulated with the aim of assisting assessment and training practice as well as providing directions for future research. The results of this review suggest that the enhancements in performance resulting from resistance training are context specific in experienced resistance-trained participants. Thus, specific conditioning could be required to achieve improvements in functional performance in this group.  相似文献   

Does self-determined motivation interact with environmental contexts to influence moderate-to-vigorous physical activity during a girls’ youth sport camp?     

Justin M. Guagliano  Gregory S. Kolt  Richard R. Rosenkranz  David A. Dzewaltowski 《Journal of sports sciences》2013,31(23):2720-2725

ABSTRACT

Objective: To explore whether basketball player’s self-determined motivation interacts with environmental contexts and coach training to influence percentage time in moderate-to-vigorous physical activity (%MVPA). Methods: A secondary analysis of data from 76 girls (mean ± SD, 10.5 ± 1.0 years) was conducted. Players were classified as high self-determined motivation (HSDM) or low self-determined motivation (LSDM) and randomised to trained (intervention) or untrained (control) coaches. Training included 2 workshops on strategies for activity-promoting practices. Girls were exposed to environmental contexts (practices and games) led by a trained/untrained coach (depending on arm) and one without coaches (free time) daily. Girls wore accelerometers each day. Using mixed random-effects models, the influence of motivation, context and training on %MVPA was analysed. Results: Trained coaches’ practices were associated with the greatest %MVPA with no difference between HSDM and LSDM players (38.28 ± 1.77%; 37.64 ± 1.80%; p = 0.66). HSDM players had significantly greater %MVPA versus LSDM players during untrained coaches’ practices (23.58 ± 1.77%; 20.51 ± 1.78%; p = 0.03). During games with trained coaches, HSDM players had greater %MVPA compared to LSDM players (23.79 ± 1.76%; 18.56 ± 1.74%; p < 0.001). No between-group difference in %MVPA during free time was found (12.85 ± 0.82%; 13.39 ± 0.84%; p = 0.64). Conclusion: The impact of individual differences in self-determined motivation on %MVPA during practices was attenuated when coaches were trained to implement activity-promoting practices.  相似文献   

Effects of a short-term pre-season training programme on the body composition and anaerobic performance of professional rugby union players

Abstract

Pre-season rugby training develops the physical requisites for competition and consists of a high volume of resistance training and anaerobic and aerobic conditioning. However, the effects of a rugby union pre-season in professional athletes are currently unknown. Therefore, the purpose of this investigation was to determine the effects of a 4-week pre-season on 33 professional rugby union players. Bench press and box squat increased moderately (13.6 kg, 90% confidence limits ±2.9 kg and 17.6 ± 8.0 kg, respectively) over the training phase. Small decreases in bench throw (70.6 ± 53.5 W), jump squat (280.1 ± 232.4 W), and fat mass (1.4 ± 0.4 kg) were observed. In addition, small increases were seen in fat-free mass (2.0 ± 0.6 kg) and flexed upper-arm girth (0.6 ± 0.2 cm), while moderate increases were observed in mid-thigh girth (1.9 ± 0.5 cm) and perception of fatigue (0.6 ± 0.4 units). Increases in strength and body composition were observed in elite rugby union players after 4 weeks of intensive pre-season training, but this may have been the result of a return to fitness levels prior to the off-season. Decreases in power may reflect high training volumes and increases in perceived of fatigue.  相似文献   

Effect of cluster set configurations on power clean technique

Abstract

The purpose of this investigation was to examine the effects of cluster set configurations on power clean technique. Ten male, recreational weightlifters performed three sets of six repetitions at 80% of one repetition max with 0 (P0), 20 (P20) or 40 seconds (P40) inter-repetition rest. During the first and second set of P0, the catch and first pull were in a more forward position during repetition 6 as compared to repetition 1, respectively. During the second set of P40, differences in horizontal displacement were found between repetitions 1 and 6 for the second pull and the loop. During the third set of P40, differences in horizontal displacement were found between repetitions 1 and 6 for the first pull, transition, and beginning of the second pull. No differences in horizontal displacement were found between repetitions 1 and 6 during P20. During each set of P0, vertical displacement decreased between repetitions 1 and 6 (1.02 ± 0.07 m vs. 0.94 ± 0.06 m; Mean ± s). Cluster set configurations led to the maintenance of vertical displacement throughout all sets. The results demonstrate cluster set configurations with greater than 20 seconds inter-repetition rest maintain weightlifting technique to a greater extent than a traditional set configuration.  相似文献   

Repurposing children’s television for the classroom: teachers’ use of “square one tv” videocassettes     

Milton Chen  Jan Ellis  Karen Hoelscher 《Educational technology research and development : ETR & D》1988,36(3):161-178

This study investigated whether a major new children’s television series on mathematics, produced primarily for an at-home audience, could be “repurposed” for classroom use. Segments were selected from the PBS children’s series, “Square One TV,” and edited into 30 videocassettes organized by curriculum topics. Teachers in two public elementary schools in Cambridge, Massachusetts, used the cassettes over a 10-week period. Both qualitative and quantitative data were collected, including teacher interviews, teacher journals of classroom use, researcher observations, a survey of student attitudes toward mathematics, and student interviews. Teachers found the reformatted cassettes to be useful motivational and instructional resources, especially in demonstrating connections between mathematical ideas and real-world situations. A videotape of teacher and student responses is available from the authors. This paper written while Dr. Chen was an assistant professor at the same school, won the Instructional Video Paper Competition marking the 25th anniversary of the Agency for Instructional Technology, Bloomington, Indiana.  相似文献
