The aim of this study was to quantify movements of Super 12 rugby players in competition because information on elite rugby players' movements is unavailable. Players were categorized into forwards [front (n = 16) and back row (n = 15)] and backs [inside (n = 9) and outside backs (n = 7)] and their movements analysed by video-based time motion analysis. Movements were classified as rest (standing, walking and jogging) and work (striding, sprinting, static exertion, jumping, lifting or tackling). The total time, number and duration of individual activities were assessed, with differences between groups evaluated using independent sample t-tests (unequal variances), while differences between halves were assessed with paired sample t-tests. Forwards had 7:47?min:s (95% confidence limits: 6:39 to 8:55?min:s, P<0.01) more time in static exertion than backs, but backs spent 0:52 (0:34 to 1:09, P = 0.01) min:s more time sprinting than forwards, and had a 0.7 (0.3 to 1.2, P = 0.01) s longer duration of each sprint. Forwards spent 7:31 (5:55 to 9:08) min:s more time in work activities (P = 0.01) and had 2.1 (1.3 to 2.8) s longer work durations (P<0.01) than backs. The results indicate frequent short duration (<4?s) work efforts followed by moderate duration (<20?s) rest for forwards, and extended (>100?s) rest duration for backs. High-intensity efforts involved static exertion for forwards (mean?±?standard deviation frequency = 80?±?17) and sprinting for backs (27?±?9). In conclusion, after nearly a decade since becoming professional, elite rugby union is still characterized by highly intense, intermittent movement patterns and marked differences in the competition demands of forwards and backs.  相似文献

This study examined determinants of underachievement as perceived by 148 Black fifth‐and sixth‐grade students in an urban school district. Explored were the respective influences of social, psychological, and cultural determinants of underachievement as perceived by Black students in three different academic programs (gifted, above‐average, and average). Students were placed into groups based on profiles of achievement behavior (Types I through V) and compared relative to their perceptions and attitudes. Findings from the statistical analyses (frequency analyses, t‐tests, analyses of variance, and multiple regression) suggest that psychological factors played the greatest role in underachievement or poor achievement motivation, and that underachievement behaviors were noted among all students, irrespective of their academic program. Implications and recommendations are suggested for educators working with gifted, above‐average, and average Black students in urban areas.  相似文献

Throughout their lives, individuals accumulate and apply lessons learned from instruction and experience. It is unclear how they transfer these lessons to become accomplished in their fields. In this exploratory study, we develop grounded hypotheses about the relationship of transfer to accomplishment. Selected individuals told stories about what they learned that influenced their major accomplishments, their sources, and timing. Findings indicate that individuality is magnified on the road to accomplishment, although shared lessons were evident. Attitudes and values, adopted and applied, seemed to play a special role in the passage from transfer to accomplishment.  相似文献

Recent education policy places a heavy emphasis on parents in relation to students' success at school. This paper explores how parents and teachers account for school success. Using membership categorisation analysis, it interrogates data collected in different interview situations across sites over a period of 20 years. The analysis shows how parents and teachers use talk as moral work to conversationally constitute particular agreed versions of the category ‘parent’. This category is interactively assembled through the use of category-bound attributes that construct deficit discourses of parents that explain student achievement. The analysis demonstrates that parents are complicit with teachers in producing versions of being a good parent wherein they are held responsible for their children's school success and that minimises the responsibility of the school. These findings raise questions both about who is responsible for schooling and about current contradictory policy emphases on parent and teacher responsibility for school success.  相似文献

The popular narrative of Wisconsin’s collective bargaining battle started out being about money. Should public employees pay more toward their healthcare? Can school districts offset state aid cuts using the additional revenue from employee healthcare contributions? Does collective bargaining have a cost? This article gives an overview of Wisconsin school boards, explains exactly how Act 10 increased their power, demonstrates why and how improved school board governance can have an impact on student achievement, reviews the changes Wisconsin school boards are making because of Act 10, and provides policy recommendations to improve both board governance behaviors, and the quality of policies enacted by school boards in the postcollective bargaining era.  相似文献
