The concept of the transfer of kinetic energy (KE) sequentially through the human body from proximal to distal segments is
an influential concept in biomechanics literature. The present study develops this area of research through investigation
of segmental sequencing of the transfer of KE by means of computer simulation. Using a musculoskeletal computer model previously
developed by the authors, driven using three-dimensional kinematic data from a single elite male golfer, combined inverse
and forward dynamics analyses enabled derivation of KE. Rigid body segments of torso, hips, arms and clubhead were examined
in line with previous literature. Using this method a driver swing was compared to a 7 iron swing. Findings showed a high
level of correlation between driver and iron peak KE and timing of peak KE relative to impact. This seems to indicate equivalent
trunk and arms linear velocity, thus force applied, for an iron shot and a driver shot. There were highly significant differences
between KE output for body segments for both clubs. In addition, peak KE magnitudes increased sequentially from proximal to
distal segments during swing simulations for both the driver and 7 iron. This supports the principle of the summation of speed.
However, timing of peak KE was not sequential from proximal to distal segments, nor did segments peak simultaneously. Rather,
arms peaked first, followed by hips, torso and club. This seems to indicate a subjective optimal coordination of sequencing.

An online survey of workload activities was circulated to academics across Australia seeking estimates for the time to undertake a range of academic-related tasks associated with teaching, research and service. This article summarises the most important findings from the teaching data of the 2059 respondents. This detail of workload data has not been reported before across the Australian university sector. The findings showing that most academics work more than 50 h per week are consistent with previous studies. Although the estimates of the individuals varied greatly, statistical inquiry indicated the median time required does not vary by experience and online teaching generally requires more preparation time than on-campus teaching. The paper proposes this methodology as a credible means to derive realistic time-based standards for other aspects of academic work and will assist university managers by providing an external benchmark upon which to develop local academic workload models. 相似文献

Neoliberal reforms in higher education have resulted in corporate managerial practices in universities and a drive for efficiency and productivity in teaching and research. As a result, there has been an intensification of academic work, increased stress for academics and an emphasis on accountability and performativity in universities. This paper critically examines these developments in institutions and draws on evidence from universities across the sector and a detailed case study in one university to identify the impacts of these changes on academic work. Given its ubiquity and the link of academic productivity to institutional experience, the paper argues that assumptions underpinning academic performance management need to be rethought to recognise the fundamentally intrinsic motivational nature of academic work. The paper explores the effects of performance management on individual academics as a case study in one institution and proposes a re-design of academic performance management to improve productivity based on the evidence. 相似文献

This discussion paper considers the identification and definition of the ‘characteristic spirit’ of publicly managed schools in the Republic of Ireland. Some international approaches to values in publicly funded schools are introduced along with relevant contextual aspects of Irish education including the cultural diversity and secularisation of modern Irish society. The Irish Education Act (1998) gives ultimate responsibility for school values and ‘characteristic spirit’ to the school ‘patron’, a role legally separate from that of school ownership and school management. The underlying values of privately managed faith-based schools are well established. However, the ‘characteristic spirit’ of publicly managed Education and Training Board schools remains largely undeveloped. Appropriate responses to this challenge are identified and discussed. 相似文献

Since being adopted by The English Football Association as the preferred format of football to be played by children aged 10 and under, mini soccer has evolved and expanded into a popular activity for children. Yet little is known about the experiences of those participating in the game. In addition, adult-organized activities such as mini soccer are increasingly seen by parents and adults as suitable pursuits for their children to participate in. Yet the perspective of the child participating in mini soccer, as with many other activities, is largely ignored in academic literature. This is especially true in the social sciences, where research has historically been done ‘on’ children, rather than ‘with’ children. In this study, we seek to address this imbalance by including children as active participants in the research process. In doing so, we devised a methodology based on audiovisual methods to create participatory conditions between children and researchers interested in investigating their experiences of mini soccer in England. Children were asked to identify aspects of their experience which they felt were noteworthy to create video recordings of critical incidents that directly involved them participating in mini soccer. These were used as a discussion tool in focus groups to explore how and why children felt the incidents were critical, and how their experience of them shaped their participation. The methodology employed helped capture children’s differentiated views of the same incidents, and highlighted the diversity of their experiences. It is recommended that similar audiovisual methodologies are employed to inform future policy and strategy development in grassroots football that includes children as participants. 相似文献

OBJECTIVE: There are three general objectives: First, to determine the number of reports of abuse made by teachers, their knowledge of child abuse laws and reporting procedures, and their perceived deterrents in reporting abuse; second, to determine if there were gender or ethnic differences in reporting; and third, to evaluate teachers responses to case vignettes. METHOD: A survey of 197 teachers was conducted. They were given a questionnaire that included demographic information, knowledge of child abuse laws and procedures, and two scenarios of legally reportable child abuse. RESULTS: Seventy-three percent of this sample reported that they had never made a report of child abuse, while those who had made reports made an average of one report. Only 11% of teachers reported that there were instances in which they believed abuse may have occurred, but failed to report. Additionally, these teachers felt that their pre- and post-service training did not adequately prepare them for abuse reporting. The most common reasons cited for not reporting abuse were fear of making an inaccurate report, feeling as though child protective services do not help families, and no apparent physical signs of abuse. There were no gender differences in reporting. The teachers' responses to the case vignettes were not consistent with their previous reports. CONCLUSIONS: In general, most teachers reported having never made a child abuse report. Although only a small percentage of teachers reported failing to report abuse, when presented with legally reportable case vignettes, many failed to report. The majority of teachers report receiving inadequate training in child abuse signs, symptoms, and reporting procedure. There is an obvious need for more education for teachers that addresses their perceived deterrents and aids them in feeling more confident in making reports of child abuse. 相似文献

Within a European context, facilitating the increased participation of marginalized groups within society has become a cornerstone
of social policy. In higher education in Ireland this has generally involved the targeting for support of individuals representing
groups traditionally excluded on the grounds of socio-economic status. More recently, people with disability have been included
in this consideration. This approach has tended to focus on physical access issues and some technical supports. However, access
is multi-faceted and must include a review of pedagogic practices, assistive provision (technological and personal), student’s
engagement with their workload (e.g. recording) and evaluation procedures: achieving accreditation levels commensurate with
ability.
This small-scale Irish study examined the experiences of two groups of young people with physical disabilities and with dyslexia
in two higher education institutions. It was apparent that for students with physical disabilities and with dyslexia, assessment
practices were fraught with additional limitations. Assessment practices were mediated for these students through the physical
environment, the backwash effect of assessment on curriculum, the availability and use of assistive technology, and through
the attitudes of staff and students. It can be concluded that access issues within higher education have been inadequately
conceptualized and as a result failed to address fundamental issues around assessment for students with physical disabilities
and with dyslexia. 相似文献

This article addresses the distinctive role that artists play in education. Although there has been a growing body of research internationally into artists involved in teaching and learning processes, the practice of artists in education in Ireland has developed in an uneven and sometimes disjointed manner. The field of ‘arts in education’ and issues surrounding its policy and practice in Ireland are investigated here. This article takes music as a focus in examining musicians' engagement in educational partnerships. Discussions around the role of artists in educational settings, successful partnerships and professional development are presented. Interviews carried out with a purposive sample of eight musicians are thematically analysed to provide meaningful insight into these debates drawn from actual practice. In this way, the article contributes to developing research into arts in education and, more specifically, music in education. In doing so, it hopes to underpin future policy, practice and stimulate further research in this area. 相似文献
