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

An Ironic Imbalance: Coaching Opportunities and Gender in Women’s Artistic Gymnastics in Australia and New Zealand     

Roslyn Kerr  Georgia Cervin 《国际体育史杂志》2016,33(17):2139-2152

Abstract

Women’s Artistic Gymnastics (WAG) is a sport designed specifically for women. With roots in ballet, calisthenics and eugenics, it was meant to showcase femininity, beauty, and encourage healthy bodies for motherhood, therefore offering socially acceptable sporting opportunities for females. This paper considers whether such sporting opportunities extended to female coaches. We examine the recruitment patterns in relation to gender of some of the top coaches in Australia and New Zealand since the 1980s, who are predominantly migrants. Using archival sources, interviews and personal experience, this paper argues that while so-called feminine or artistic sports can offer greater opportunities for female coaches, WAG in Australia and New Zealand remains dominated by male coaches, who have held the majority of the head coach positions and in many cases, been actively recruited from overseas. The few females who have been employed in top positions have been appointments of ‘convenience’ rather than reflective of a shift away from these gendered employment patterns. Thus, while its creation as a specifically feminine sport may lead WAG to be viewed as a site of increased opportunities for women coaches, deeper exploration reveals an unresolved tension between the use of male and female coaches.  相似文献   

Operationalizing and validating disciplinary literacy in secondary education     

Hiller A. Spires  Shea N. Kerkhoff  Abbey C. K. Graham  Isaac Thompson  John K. Lee 《Reading and writing》2018,31(6):1401-1434

The goal of this study was to define the construct and establish the validity of disciplinary literacy, which has recently gained attention from the implementation of the Common Core State Standards (National Governors Association Center for Best Practices & Council of Chief State School Officers in Common Core State Standards for English language arts & literacy in history/social studies, science, and technical subjects [PDF]. Authors, Washington, DC, 2010). After defining disciplinary literacy in the four core disciplines of English language arts, science, history and social studies, and mathematics, scales were developed and administered to a snowball sample of professionals nationwide, with 857 respondents. The data showed evidence of disciplinary literacy as a multidimensional construct with three related factors: source literacy, analytic literacy, and expressive literacy. Based on EFA and CFA results, we can conclude that there are at least three types of literacy in operation among the four core disciplines. The three factors of literacy varied significantly by the four core disciplines of English/language arts (ELA), science, history and social studies, and mathematics, supporting the notion that each discipline uses literacy uniquely. This is the first study of its kind to attempt to define, quantify, and validate the construct of disciplinary literacy.  相似文献

Growing up in a tourist destination: developing an environmental sensitivity     

Antonia Canosa  Anne Graham  Erica Wilson 《Environmental Education Research》2020,26(7):1027-1042

Abstract

This paper explores how the socio-cultural milieu of a community may foster a sense of environmental stewardship among children and young people. Ethnographic fieldwork, carried out in a popular tourist destination in Australia, revealed that the overt impacts of tourism activity such as littering provoke negative feelings among children and young people; these perceptions can in turn translate into a sensitivity towards the environment. While debated in some circles, a Significant Life Experiences (SLE) lens is useful in understanding children and young people’s lived experiences of – and sensitivity to - environmental issues in the communities where they are raised. SLE is employed in this article to explore how a sense of stewardship towards the environment is developed among children and young people growing up in a tourist destination. Findings suggest they actively contribute to protecting the environment in a variety of ways from regular beach clean ups and educating visiting tourists to participating in rallies and anti-development protests.  相似文献   

‘Education for equality’ and ‘education for life’: examining reading literacy and reading interest in Papua New Guinea primary schools1     

Sarah Hopkins  Graham Ogle Corresponding author  Lisette Kaleveld  John Maurice  Betty Keria  William Louden 《Asia-Pacific Journal of Teacher Education》2005,33(1):77-96

Reading literacy and reading interest was examined in four primary schools in Papua New Guinea: in an international, suburban, settlement and village school. In this paper we present a summary of findings located within a local context and examine the implications as viewed through two lenses. From an ‘educational for equality’ perspective, the findings suggest a critical need to re‐evaluate the use of national testing to select children for further education and address the serious shortage of reading books in school libraries. From an ‘education for life’ perspective, the findings indicate a continuing need for community‐based actions together with innovative teacher education programs aimed at developing ways of strengthening the connections between home and school.  相似文献   

Improving the compositions of students with learning disabilities using a strategy involving product and process goal setting.     

S Graham  C MacArthur  S Schwartz  V Page-Voth 《Exceptional children》1992,58(4):322-334

This study was conducted to determine if a planning and writing strategy would improve the essay writing of students with learning disabilities. Four participants were taught a strategy designed to facilitate the setting of product and process goals, generation and organization of notes, continued planning during writing, and evaluation of goal attainment. Training effects were investigated using a multiple probe design across subjects. Strategy instruction had a positive effect on students' essay writing performance and knowledge of the writing process, and effects were maintained over time.  相似文献

A Comparative Sociology of School Knowledge     

John Shepherd  Graham Vulliamy 《British Journal of Sociology of Education》1983,4(1):3-18

Despite a recently renewed theoretical interest in both North America and in Britain in the sociology of school knowledge, we still have little, if any, comparative empirical material from these two continents. This paper reports the findings of a sociological study, designed to replicate the previous English empirical work by Vulliamy, into music teaching in Ontario high schools. Unlike in England, no overt culture clash was found in Ontario schools between ‘school’ music and ‘students’ ‘ music, both because of the wider scope of ‘what counts as school music’ in Canada and because music is not a compulsory school subject there. However, by focusing upon the deep structure of the pedagogical process, as opposed to surface features of classroom interaction, it is argued that particular ideologies of the dominant musical culture are transmitted in very similar ways in both contexts. What is shared is a conception of music as equatable with musical notation. The ideological significance of this is pinpointed in an analysis of the structurally homological relationship between different musical languages and the social/‐cultural contexts of their creation. The processes of school music teaching not only contribute to the legitimation of a dominant musical ideology, but also to much more pervasive ideological assumptions underpinning capitalist societies.  相似文献
