Elite rugby union teams currently employ the latest technology to monitor and evaluate the physical demands of training and games on their players. Tackling has been shown to be the most common cause of injury in rugby union, yet current player monitoring technology does not effectively evaluate player tackling measurements. Currently, to evaluate measurements specific to player tackles, a time-consuming manual analysis of player sensor data and video footage is required. The purpose of this work is to investigate tackle modeling techniques which can be utilised to automatically detect player tackles and collisions using sensing technology already being used by elite international and club level rugby union teams. This paper discusses issues relevant to automatic tackle analysis, describes a technique to detect tackles using sensing data and validates the technique by comparing automatically detected collisions to manually labeled collisions using data from elite club and international level players. The results of the validation show that the system is able to consistently identify collisions with very few false positives and false negatives, achieving a recall and precision rating of 0.933 and 0.958, respectively. The aim is that the automatically detected tackles can provide coaching, medical and strength and conditioning staff with objective tackle-specific measurements, in real time, which can be used in injury prevention and rehabilitation strategies. 相似文献

To date, few scholars have examined organisational change in the sport industry, with the majority focusing on forces driving change. Only a handful have investigated responses to change, primarily centering upon factors contributing to resistance. Historically, most work in measuring attitudes has placed them on a bipolar continuum ranging from negative to positive. Recently, though, researchers have presented data to support an indifference-ambivalence attitudinal dimension characterised by evaluative tension. There have been few studies, however, that have examined ambivalence towards organisational change. Therefore, this research was undertaken to investigate ambivalence towards organisational change in a Football Championship Subdivision intercollegiate athletic department in the U.S. Through a case study, we demonstrate that ambivalence was a salient response to change, and that intrapersonal conflict, perceived lack of institutional support, managerial turnover, and previous negative experience with change served as antecedents. We then highlight the theoretical and practical significance of our study. 相似文献

Two studies investigated children's metacognition about everyday reasoning, assessing how they distinguish reasoning from nonreasoning and "good" reasoning from "bad." In Study 1, 80 1st graders (6-7 years), 3rd graders (8-9 years), 5th graders (10-11 years), and adults (18+ years) evaluated scenarios where people (a) used reasoning, (b) solved problems with nonreasoning approaches, or (c) reacted appropriately but automatically to events. All age groups distinguished reasoning from type (b) nonreasoning cases, but age-related improvement occurred for type (c) cases. Study 2 tested 160 1st, 3rd, 5th graders' and adults' evaluation of good and bad reasoning processes, finding 2 developmental changes: initial improvement in discriminating thinking processes by 3rd grade, and emergence of an adult-like, process-focused (vs. outcome-focused) concept of thinking quality by 5th grade. 相似文献

We evaluated the effects of one year of schoolwide cluster grouping on the academic achievement growth of gifted and non-identified elementary students using a piecewise multilevel growth model. Scores from 186 non-identified and 68 gifted students’ Measures of Academic Progress Reading and Math scores were examined over three school years. In 2008–2009 within-class ability grouping was used. In 2009–2010 schoolwide cluster grouping was implemented. In 2010–2011 students once again were grouped only within classrooms by ability and students identified as gifted were spread across all classrooms at each grade level. Results suggest that schoolwide cluster grouping influenced student performance in the year following its implementation, but only for mathematics and not the area of reading. 相似文献

Seventy‐seven new academics – 59 at a large, public university in the UK and 18 at a medium‐sized, private comprehensive university in the USA – were asked to read an extract of an article on the scholarship of teaching and learning (SoTL) and mark the text according to categories of difficulty or dislike. Analysis of the data revealed six main linguistic barriers in the text: specialist vocabulary, passive constructions, pronouns, figurative language, derivations and poor editorial standards. These barriers were similar at both institutions, suggesting they apply across different contexts. Contrary to expectations, no conclusive disciplinary‐based distinctions were detected. Implications for both readers and writers are explored and proposals are made for developing a literary style in SoTL literature that is simultaneously accessible and credible. Soixante‐dix‐sept nouveaux enseignants – cinquante‐neuf provenant d’une université publique britannique de grande taille et dix‐huit provenant d’une université privée américaine de taille moyenne – ont lu l’extrait d’un article portant sur le scholarship of teaching and learning (SoTL) et ont identifié les parties qu’ils jugeaient difficiles ou qu’ils n’appréciaient pas. Une analyse des données révèle la présence de six barrières linguistiques principales dans le texte: le vocabulaire spécialisé, les constructions passives, les pronoms, le langage figuratif, les dérivations et des standards de rédaction de piètre qualité. Ces barrières étaient similaires dans le cas des deux institutions, ce qui suggère qu’elles sont applicables dans des contextes différents. Contrairement aux attentes, aucune distinction reposant sur les disciplines permettant de tirer des conclusions n’a pu être détectée. Les implications pour les lecteurs et les rédacteurs sont explorées et des propositions visant à développer un style littéraire pour la documentation portant sur le SoTL qui soit à la fois accessible et crédible sont formulées. 相似文献

Inclusive education has been introduced through a number of policy developments in Malaysia over the last 10 years but there is little research investigating the extent and nature of inclusive education for preschoolers with special educational needs (SEN). This study surveyed both regular and special education teachers in Malaysian integrated preschools asking them about the level and nature of inclusion taking place in their preschools and their perceptions and beliefs about inclusion. There was little evidence of practices of inclusion taking place. Both regular and special educators agreed that SEN should be educated alongside their peers in a school but were unlikely to agree that the SEN students should be in the same classroom. Factors identified as influencing inclusion included school culture, skills and competency, guidance and information, workload and students' disabilities. More guidelines and support are required for successful inclusion in Malaysian integrated preschools. 相似文献

ABSTRACTUndergraduate research experience has been shown to enhance student learning and improve persistence in science, technology, engineering, and mathematics (STEM). Researchers studying undergraduate research experiences have largely focused on student outcomes and have seldom investigated the outcomes of graduate and postdoctoral mentors. Here, we report a non-credit, year-long mentor professional development program designed for graduate students, postdoctoral scholars, and research staff in STEM. Mentors attended a series of six interactive and discussion-based workshops and mentored first-year undergraduate students in independent summer research projects. We report evaluation findings for three mentor cohorts using a combination of qualitative analysis of mentoring philosophies and quantitative assessment of pre- and post-surveys about mentoring objectives and skills. Results indicate that mentors gained self-efficacy in some objectives and skills. However, many other objectives and skills remained unchanged. We explore possible explanations for the lack of more broad-scale gains across survey items and present ideas for program improvement. 相似文献

As universities prepare educational leaders for twenty-first century schools, the quality and authenticity of the internship experience require both the strengths of university faculty and the expertise of practitioners to create authentic experiences that seek to bridge the theory-to-practice divide. One mechanism to achieve this is through quality mentorship by school- and central-office-based personnel during the internship experience. A central aspect of this professional relationship is the ability for the mentor to provide access to quality activities that will prepare the aspiring leader for his/her first administrative position. This exploratory study examined language utilized by interns in their time logs as well as information gleaned from preliminary surveys of both interns and mentors upon completion of their experience. Findings revealed the complexity of language analysis and revealed a need for understanding activities of interns and interactions with mentors in a contextual fashion. 相似文献

Many secondary schools are now establishing Nurture Groups, an intervention primarily designed for infant school-aged children. However, there is little research indicating that this intervention can be applied effectively to secondary settings. The main aim of this research was to explore how Nurture Groups are implemented into the secondary sector and whether they can be a beneficial intervention for children with social, emotional and behavioural difficulties. The implementation of three secondary school Nurture Groups was examined through the views of 17 secondary school staff and eight parents using focus groups, and six children who had attended the Nurture Groups through individual interviews. Findings indicated that secondary school Nurture Groups can be a valued resource and have benefits for young people. However, they often have a different emphasis from those originally devised by Boxall, because of the developmental differences between sectors. Recommendations for secondary school Nurture Group practitioners are provided. 相似文献
