The efficacy of talent selection criteria in the Australian Football League

ABSTRACT

This study investigated the association between talent selection criteria, draft order and match performance in professional Australian Football players. Physical performance results from the Australian Football League (AFL) National Draft combine and non-performance based talent selection criteria were collated for all players drafted in the National Draft with selections 1–80 between 2003 and 2008 (n = 318). Match performance was assessed via the AFL Player Ranking metric that was provided by a commercial statistical provider (Champion Data Pty Ltd). A combination of stepwise multiple regression and linear mixed model analyses examined the influence of National Draft combine physical performance assessments and non-performance based talent selection criteria on draft order and future match performance. Earlier draft selection was associated with Under-18 all Australian team selection, height, Under-18 National Championship participation and indigenous status. The 20 m sprint and state of origin were associated with later draft selection. Under-18 all Australian team selection increased both Player Ranking/game and total Player Ranking. Under-18 all Australian team selection displays efficacy for selecting players with the potential for success.     

与“海象”冰海共舞

寒冷的12月,很多人都应该进入了冬眠或半冬眠状态,足不出户,舒舒服服地蜷缩在被窝里睡懒觉吧。但一些生活在北方的人偏要唱反调,在冰天雪地的户外进行传统的冬季运动——冬泳。这对长期生活在南方的Grace来说确实很不可思议。冬泳究竟有什么魅力,为什么能吸引这么多人参与呢?它对健康真的有那么多好处吗?想知道答案,一起看看本文作者在俄罗斯的冬泳经历。Grace提醒一下,想尝试冬泳的同学务必注意安全哦!     

Rhetorical sensitivity recast: Theoretical assumptions of an informal interpersonal rhetoric

Since it was introduced in 1972, the concept of rhetorical sensitivity has generated much interest among communication scholars. However, the theoretical assumptions underlying the concept remain unarticulated. This essay identifies the assumptions implicit in the concept of rhetorical sensitivity and examines how these assumptions extend traditional rhetorical thought in useful ways to interpersonal communication.     

Using student-generated questions for student-centred assessment

In small groups, medical students were involved in generating questions to contribute to an online item bank. This study sought to support collaborative question‐writing and enhance students’ metacognitive abilities, in particular, their ability to self‐regulate learning and moderate understanding of subject material. The study focused on supporting students to write questions requiring higher order cognitive processes. End‐of‐year formal examinations comprised 25% student‐generated questions (SGQs), while mid‐year examination items were completely unseen. Data were gathered from repeated administration of a questionnaire and from examination results. No statistically significant changes were identified in self‐rated monitoring of understanding and regulation of learning. The activity of generating questions supported students to work collaboratively in developing questions and answers. The bank of questions was appreciated by students as a source of revision material, even though it was not strongly focused on higher order processes. Based on scores, it would appear that many students chose to memorise the question bank as a ‘high‐yield’ strategy for mark inflation, paradoxically favouring surface rather than deep learning. The study has not identified directly improvements in metacognitive capacity and this is an area for further investigation. Continual refinement of the study method will be undertaken, with an emphasis on education of students in developing questions addressing higher order cognitive processes. Although students may have memorised the questions and answers, there is no evidence that they do not understand the information.     

Modeling aspects of print-processing skill: implications for reading assessment

This study examined how well elementary students?? performance on a set of commonly-used reading assessments conformed to a model of automatic print processing. The assessments included measures of word recognition-untimed, word recognition-timed, oral reading accuracy, oral reading rate, silent reading rate, and spelling. The proposed print-processing model, based on the work of Perfetti (1992) and Share (1995), held that contextual reading accuracy is directly related to automatized word knowledge which is directly related to reading rate. Structural equation modeling showed that the performance data had an acceptable fit to the proposed model and to a second, post hoc model in which automatic word recognition is directly related to contextual reading accuracy. However, additional regression analyses tended to favor the initial model. Because the six print-processing components in this study proved to be reliable and related, and because two of the components (word recognition?Ctimed and spelling) are seldom used in conventional reading assessments, the results have important implications for practice.     

Enrollment in Physical Education Is Associated With Overall Physical Activity in Adolescent Girls

Little is known about population-level contributions of school physical education to overall physical activity (PA) in youth. Because PA levels are lower in girls than boys, it is particularly important that the effects of PE programs in adolescent girls be understood. Thus, the purpose of this study was to determine the association of enrollment in physical education and overall physical activity participation in adolescent girls. A measurement protocol was administered to cross-sectional samples of 8th-, 9th-, and 12th-grade girls participating in a school-based PA intervention study (1998–2003). PA was assessed with the 3-Day Physical Activity Recall. Three-way analyses of variance were performed to compare groups formed on the basis of physical education enrollment. For each grade group of girls, those who were enrolled in physical education reported more moderate-to-vigorous PA and more vigorous PA than nonenrolled girls. When activity in physical education classes was deleted, 8th-and 9th-grade physical education enrollees were not more active than nonenrollees; however, 12th-grade physical education enrollees remained more active than nonenrollees. Girls who were enrolled in physical education were more physically active than nonenrolled girls in all three grade levels. These findings suggest that expanded enrollment in physical education may increase American adolescent girls' PA level.     

Domain Specificity,Task Specificity,and Expert Performance

Abstract

Initial performance, final performance, and the amount of learning in 50 trials of the rho test motor performance task were obtained on 120 boys and girls, aged 10 and 14. Initial and final performance showed significant age, sex, and age w/i sex differences. The amount of learning showed no differences.     

Creative pedagogies and collaboration: an action research project

This action research study involves nine elementary school teacher-researchers, one university faculty member, and one graduate student engaged in developing creative pedagogical practices in one elementary school in an urban school in Alabama, USA. Participants found that a teacher’s experience of agency and their ability to work creatively depended upon a clear articulation of structures and the identification of areas of flexibility and possibility. Further, participants endeavored to promote avenues for ongoing communication and collaboration between teachers and the principal with the view that creativity based in communication would sustain transformative dialogues in the school.
