Time motion analysis of 2001 and 2002 super 12 rugby     

Duthie G  Pyne D  Hooper S 《Journal of sports sciences》2005,23(5):523-530

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   

EditorialKeeping information centre stage amid changing scenery     

Maria J Grant 《Health information and libraries journal》2010,27(2):91-92

With conference season upon us, consideration is given to the importance of subject‐specific and library association conferences. The biennial Health Libraries Group (HLG) conference meets both these criteria and takes place in Greater Manchester in July. The conference provides an opportunity for peer‐to‐peer learning, identifying new trends and professional rejuvenation. An open invitation is given to attend the Health Information and Libraries Journal‘Writing for Publication’ workshop at the HLG conference. An overview of three bursaries available from the Health Libraries Group and Library and Information Research, both groups of the UK Chartered Institute of Library and Information Professionals (CILIP) is provided. The bursaries offer opportunities to cover the costs of registration and travel expenses to national and international conference.  相似文献   

A Case Study of Needs Assessment in Teacher In-Service Development     

Heidi L. Schnackenberg  Krista Luik  Yael C. Nisan  Colleen Servant 《Educational Research and Evaluation》2013,19(2-3):137-160

In 1996, The Ministry of Education of the Province of Quebec authorized a plan to support the integration of new information technologies and communications (NTIC) in its schools. An expenditure of $318 million dollars was announced for the purchase and upgrade of hardware and software. In response to this initiative, The Concordia University Centre for the Study of Learning and Performance (CSLP) approached the Quebec schoolboards, proposing partnerships between them and the Centre to facilitate the integration of these technologies into pedagogical practices. This article describes a needs assessment performed by the university in two Quebec elementary schools. The collected data revealed that teachers are currently using computers primarily for word processing and to prepare report cards. While they are somewhat dissatisfied with previous professional development, they are still highly interested in receiving training on how to better incorporate technology into their pedagogical practices. General recommendations and a workshop are outlined.  相似文献   

Young offenders in New South Wales,Australia and the need for remedial sexual health education     

Grant Mistler  Kristie Kirkwood  Emily Potter 《Sex education》2013,13(4):439-449

The 2005–2008 Australian National Sexually Transmissible Infections Strategy identifies young people as a key target group in need of sexual health education, screening and management. For young people who are in contact with the New South Wales (NSW) juvenile justice system, a dire need for remedial sexual health education exists. NSW young offenders indicate initiation of sexual activity at a younger age than their peers, higher numbers of sexual partners, infrequent condom use and higher rates of sexually transmitted infections. They also report family instability, poor accessing of health services, and low school attendance: all factors that result in poor sexual knowledge and health outcomes. An examination into the cognitive profile of these young offenders indicates remedial education for this group may require a dual approach in order to redress their specific circumstances and needs. The first approach should target young offenders who simply missed out on stages of sexual health information in the school curriculum. The second approach requires a tailored teaching methodology more appropriate for a group with atypical cognitive profiles. Both approaches need to engage an educative model that acknowledges that these disadvantaged young people are already sexual active; and that many did not have the benefit of an informed or consensual decision making processes. More importantly, the tailoring of a sexual health education program to these young people needs to resonate with teaching to a cognitively distinctive population who have experienced higher than usual rates of alcohol and other drugs abuse, and higher than usual episodes of physical and emotional abuse and neglect.  相似文献   

Fact or folklore? Exploring “Myths” about outdoor education accidents: Some evidence from New Zealand     

Grant Davidson 《Journal of Adventure Education & Outdoor Learning》2013,13(1):13-37

Abstract

This paper provides analysis on the frequency and nature of accidents and near accidents that have occurred in larger outdoor education centres in New Zealand. This is the first time that information of this type has been collected and analysed in New Zealand.

All 25 of the known outdoor education organisations employing three or more full-time staff were invited to participate in a study that would extract and review data from their records about accidents and near accidents. Twelve agreed to participate.

The data collected is analysed in the context of various myths that are often heard referred to by the outdoor education community. These are that: 1. i.focusing on minor incidents prevents major accidents occurring,

2. ii.selecting activities with high perceived risk but low real risk reduces exposure to accidents,

3. iii.more accidents occur while under the supervision of male rather than female instructors,

4. iv.accidents are more likely in the afternoon than the morning, and

5. v.outdoor education is dangerous compared to other risks in life.

The results lend some support to the factual nature of “myths” iii and iv, but help consign “myths” i, ii and v to the category of folklore. These results provide insights that may assist in developing strategies to improve safety in outdoor education.

In view of the current size and importance of the outdoor education sector in New Zealand and its likely future growth, one of the main recommendations arising from this study is for the establishment of a national system to formally record and report incidents and accidents.  相似文献   

China's recruitment of African university students: policy efficacy and unintended outcomes     

Heidi Østbø Haugen 《Globalisation, Societies & Education》2013,11(3):315-334

This article explores how Sino-African relations are affected by the growing number of Africans who pursue higher education in China. China actively recruits African university students in order to increase soft power and generate income from the export of education services. Semi-structured interviews with African university students suggest that China fails to reach these policy objectives because the students are disappointed with the quality of the education they receive. However, the students engage in trade and contribute to the fast-growing export of Chinese products to African markets, thereby reinforcing the ties between China and Africa in unintended ways.  相似文献   

Mixed Mode Latent Class Analysis: An Examination of Fit Index Performance for Classification     

Grant B. Morgan 《Structural equation modeling》2013,20(1):76-86

This Monte Carlo study examines the performance of fit indices commonly used by applied researchers interested in finite mixture modeling for the purposes of classification. Conditions for the simulation study were selected to reflect conditions found in applied educational and psychological research. The factors included in the investigation were metric level of indicators, sample size, and class prevalence. All models contained a combination of categorical and continuous indicators. All categorical indicators were dichotomous, and continuous indicators were normally distributed. The fit indices examined were Akaike’s information criterion, Bayesian information criterion (BIC), sample size-adjusted Bayesian information criterion (SSBIC), integrated classification likelihood criterion with Bayesian-type approximation, and Lo–Mendell–Rubin likelihood ratio test. Overall, SSBIC tended to identify the correct solution with higher frequency than other indices. BIC tended to identify the correct solution with higher frequency than the other indices in models with more continuous than categorical indicators, or when rare classes were absent.  相似文献   

Fostering partnerships with families: academic service-learning in the Little Village     

Mary Knight-McKenna  Heidi L. Hollingsworth  Nicole Ammerman 《Journal of Early Childhood Teacher Education》2013,34(2):57-73

ABSTRACT

Strong family-teacher partnerships increase family engagement, promoting positive outcomes for children. Early childhood educators need knowledge, skills, and dispositions for establishing strong, meaningful partnerships with diverse families. This research investigated the impact of academic service-learning (ASL) on undergraduate students’ knowledge, skills, and dispositions for partnering with culturally and linguistically diverse families to promote young children’s early academic learning. Participants included nine undergraduates in an early childhood teacher preparation course, ten culturally and linguistically diverse families, and thirteen 2- to 5-year-old children. In this mixed-methods study, written student ASL reflections, pre- and post-ASL student surveys, and parent evaluations were analyzed. Three themes emerged from the analysis: (1) Students entered the ASL experience with excitement and a mostly positive approach; (2) Early to mid-semester, students articulated a high degree of nervousness and discomfort as well as challenges to partnership-building, yet also noted family interest and engagement; and (3) Mid- to late semester, most students expressed their growing confidence in their own skills for relating to diverse families, and identified family strengths. Our findings support ASL as an effective teacher-preparation pedagogy to help students build family-teacher partnerships.  相似文献

Politics,Paradoxes and Pragmatics of Happiness     

Grant Duncan 《Culture, Theory & Critique》2013,54(1):79-95

European leaders and the popular media have shown a new-found interest in happiness as a socio-political value and goal. A growing body of research attempts to identify the conditions under which humans experience the highest levels of happiness, life-satisfaction or subjective well-being. This essay examines what makes a contemporary science and politics of happiness possible by taking a critical look at such efforts to define, measure and promote happiness, while seeking out a range of diverging, often paradoxical, cultural discourses of happiness. The essay covers the following themes: happiness is attainable; happiness is lost; happiness is obligatory; happiness is impossible; and, happiness is inauthentic. The essay critically examines political uses of the word happiness, disrupting received opinions about this contested term.  相似文献
