Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.  相似文献

Human integration through Olympism education: a pragmatic engagement of youths in a war-torn society     

Samantha Nanayakkara 《Sport, Education and Society》2016,21(4):623-643

This paper delineates the findings of a mixed methods study that investigated how Olympism education could strengthen competencies of human integration through delivery of physical, social, and critical literacy and conflict resolution literacy. The study introduced a curriculum model integrating Olympism values and conflict resolution strategies for the purpose of facilitating human integration. This integrated curriculum model was then tested among a group of young students who represent the two main ethnic groups Sinhalese and Tamils, in a war-torn society in Sri-Lanka. The intervention of this study provided pragmatic involvement for young students as the representatives of the next generation, in order to teach them the convergence and contradictions of perceptions of social reform ideals through sport. Results revealed that conflict resolution strategies combined with Olympism education integrated curriculum intervention significantly improved young students’ conflict resolution competencies, regardless of their gender or ethnicity. This study demonstrated significant gains in the ability of young students to learn about human integration through learning about Olympism within sport and physical education lessons, in regards to effective conflict resolution.  相似文献   

The university brand and social media: using data analytics to assess brand authenticity     

James Pringle  Samantha Fritz 《Journal of Marketing for HIGHER EDUCATION》2019,29(1):19-44

Recent economic pressures have demanded higher education institutions respond with strong, authentic brand promises. This mixed method multi-case study explored the authenticity of common brand promises at three Universities in Canada through Twitter and Facebook postings from February to April 2016 using a cloud-based text and network analytic tool. Our study revealed the content shared on social media channels, while largely trustworthy, was fraught with shades of gray and revealed that sometimes brand promises were used against the university when they appeared disingenuous or threatened institutional norms around equity and social justice. Further, social media strategies are still largely limited to push notification suggesting universities are missing opportunities to strengthen their brand and counter negative messaging. For marketing managers it reinforces investments should be directed toward creating engaging and authentic content that can be expressed through multiple touch-points including social media and this can be monitored through low-cost analytic tools.  相似文献   

Psychosocial correlates of child abuse potential in multiply disadvantaged adolescent mothers     

Budd KS  Heilman NE  Kane D 《Child abuse & neglect》2000,24(5):611-625

OBJECTIVE: This study had two aims: First to examine psychosocial correlates of child maltreatment risk, and second to assess the validity of the CAP Inventory (Milner, 1986) with multiply disadvantaged teenage mothers. METHOD: Participants were 75 adolescent mothers who were wards of the Illinois child protection system. Mothers (aged 14-18) and infants participated in home-based psychosocial assessment of personal and parenting functioning. Group comparisons examined differences for mothers with elevated versus normal versus invalid CAP scores due to faking good. RESULTS: Findings indicated that abuse risk groups differed on emotional distress, social support satisfaction, reading achievement, and years of education, but not on parenting beliefs or quality of child stimulation. Differences favored the normal over the elevated risk group in all significant comparisons, whereas mothers with elevated faking good differed from normals only in lower reading achievement. Multiple regression analysis highlighted emotional distress, support dissatisfaction, and low achievement as significant predictors of greater abuse risk. CONCLUSIONS: Despite sharing multiple disadvantages, adolescent wards are a heterogeneous group who show different levels of psychosocial functioning corresponding to levels of child maltreatment risk. The findings provide support for the concurrent validity and clinical applicability of the CAP Inventory with disadvantaged teenage mothers.  相似文献   

Managing Headship Transitions in U.S. Independent Schools     

Pearl Rock Kane  Justin Barbaro 《Peabody Journal of Education》2016,91(5):616-627

Headship transitions in U.S. independent schools represent critical organizational events that affect multiple school constituencies, including faculty, staff, and students. With recent projections forecasting a high level of impending headship transitions in independent schools, this paper seeks to capture how second-year U.S. independent school heads (n = 16) describe their transition experiences in order to provide insights into how boards, heads, and school communities can provide meaningful supports for their incoming school leaders. Further recommendations for practice and research are also provided.  相似文献   

The relation of multiple-schedule behavioral contrast to deprivation,time in session,and within-session changes in responding     

McSweeney FK  Swindell S  Murphy ES  Kowal BP 《Learning & behavior》2004,32(2):190-201

Pigeons' keypecking was reinforced by food on baseline schedules of multiple variable interval (VI) x VI x and on contrast schedules of multiple VI x VI y. Deprivation of food was varied by maintaining subjects at 75%, 85%, and 95% (+/- 2%) of their free-feeding weights. Positive and negative behavioral contrast were observed. The size of the contrast was not systematically altered by changes in deprivation. Positive and negative contrast were both larger later in the session than they were earlier. Within-session decreases in responding were steeper for the baseline than for the contrast schedules for positive contrast. Within-session decreases were steeper for the contrast than for the baseline schedules for negative contrast. These results were predicted by the idea that different amounts of habituation to the reinforcer during the baseline and contrast schedules contribute to behavioral contrast. The results show that contrast occurs under conditions that reduce the effect of the following component. The results support the assumption that positive and negative contrast are produced by symmetrical theoretical variables.  相似文献   

Language development: A complex,systematic, and natural process     

Janet H. Kane  Karen Sheingold 《Early Childhood Education Journal》1980,8(2):39-54

Conclusions Although we do not understand very well what the processes are that contribute to language development, it is clear that communication plays a central role. As children strive to become increasingly skilled at communicating their ideas (White, 1959), as they have increasingly complex ideas to communicate (Piaget, 1955), and as they encounter an increasingly diverse set of people with whom to communicate (Brown, 1973), they must learn to use language which is richer and more flexible.When children come to school or to a day care center they already know a great deal about language. They have readily and actively mastered words, sentences and forms of communication which they need in their own family and community. In their new environment—the school or center—children's language development can further be fostered by adults who are receptive to children's efforts at communication. Adults who encourage children to use language in new ways, who attend to what children mean to say and who recognize that children's errors are often not mistakes, are likely to play a positive role in children's language development.Janet H. Kane and Karen Sheingold are on the Staff at Bank Street College of Education.  相似文献
