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

Abstract George Brown Goode, a former Assistant Secretary of the Smithsonian in the late 1880s, said that the nature of museum work is not only knowledge creation, but also knowledge dissemination, and, ultimately, learning: “The museum likewise must, in order to perform its proper functions, contribute to the advancement of learning through the increase as well as through the diffusion of knowledge” (1991, 337). Elaine Heumann Gurian noted that: “The use of the Internet will inevitably change museums. How museums respond to multiple sources of information found on the Web and who on staff will be responsible for orchestrating this change is not yet clear. The change, when it comes, will not be merely technological but at its core philosophical” (2010, 95). The catalyst for this change—and for accelerating the pace of change—is Web 2.0.  相似文献

This sub‐study is part of a longitudinal naturalistic investigation monitoring the social behaviour of young children (3‐8‐year‐olds) before and after the arrival of broadcast television in St Helena, South Atlantic.

Children's free‐play behaviour in first school playgrounds was videotaped in 1994 (pre‐tv), and in 1995 and 1996 (post‐tv), and then coded and analysed by trained observers. Findings showed no significant differences in children's behaviour either across the availability of broadcast television (i.e. CNN) or with the addition of further channels (CNN plus others).  相似文献

Acknowledging the realities and responsibilities of power is a precondition to using it wisely. The claim that there has been a shift in power away from the formal providers of education towards the individual consumer is one that needs closer investigation. This paper uses the mathematics of cooperative multiperson game theory to analyse the relative strengths of the various representative groupings on three different models of school governing bodies. Only a basic knowledge of mathematics is assumed as the various coalitions are analysed and compared, and conclusions drawn about the relative power of major and minor factions. Voting strategies, suggested payoffs for winning coalitions and implications for committee-forming are fully examined. The paper is based on the author's direct experience of school amalgamations in the border region of Ireland. An extended consideration of the theory of voting in multiperson games can be found in his book Decision-Making and Game Theory (2002, Cambridge University Press).  相似文献

The temporal discounting literature has demonstrated that the loss in value for delayed outcomes is most accurately modeled using a hyperbolic discounting equation. The hyperbolic-shaped function not only describes the shape of discounting for monetary outcomes, but also for other tangibles, such as alcohol, candy, CDs, erotica, cigarettes, cocaine, books, and DVDs. Furthermore, this hyperbolic shape has important theoretical implications. Despite the broad list of outcomes that are hyperbolically discounted, one class of outcomes has only recently received attention: social interactions. For the present study, we used standard binary-choice discounting procedures to explore the function that most accurately describes the change in value of delayed social interactions. The results from the present study suggest that, for 93 participants, the same equations (exponential, hyperbolic, and hyperboloid) used to describe the discounting of nonsocial commodities also describe the relation between delay and the value of social interaction. Similar to previous findings for nonsocial outcomes, the hyperbolic-shaped models provide a fit to the data superior to that of the exponential model.  相似文献

本文解读了德里达对康德和席勒论现代大学起源的著作的阐述,表明那些试图监督和掌控当代大学的理论立场本身也不知不觉地遭到了解构和颠覆.接着,文章考察了当今两个把文科当作现代大学守卫者和监督者的例子.两者都成为德里达辨别出来的解构置换类型的牺牲品.文章还讨论了德里达本人对现代法国大学的制度性干预背后的不同理由.该讨论引向本文的结论,即我们应该像为社会科学和自然科学的纯粹研究辩护一样为人文科学中的纯粹研究辩护,但不应该把经典文科提升到享受特权的优越地位.  相似文献

Young children with autism spectrum disorder (ASD) are increasingly being included in early childhood classrooms that include typically developing peers and in general education classrooms once they enter school. Many of these learners have the requisite academic skills to be successful, yet their social communication and behavioral challenges often impede their successful inclusion in general education settings. The challenges educators may experience when interpreting and responding to some behaviors exhibited by young students with ASD are explored and analyzed using an illustrative case vignette of a Kindergarten child with ASD. Recommendations for analyzing the communicative function of children’s behavior and for embedding social communication opportunities in inclusive classroom settings are described.  相似文献
