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

Mergers are common phenomena in higher education institutions. Improving educational quality is typically one of the stated goals of university mergers. Yet, little information exists about how merging institutions approach this goal. This paper presents results from a study of planning documents created prior to four mergers in the Finnish higher education system. These documents show that there was little concrete attention given to the educational issues related to the mergers. Most attention was placed on administrative issues and issues related to research. When educational issues were mentioned, it was almost always in the form of vague goals with few details provided about how the goals were to be reached. We conclude that this lack of attention to the educational aspect of mergers is a significant weakness of the planning process in these mergers. 相似文献

In England children must start school after their fifth birthday, but it is common for children to start when they are four in what is known as the Reception class. The Performance Indicators in Primary Schools (PIPS) project collected data on 1700 pupils’ early mathematics and pre/early reading levels at the start and end of their Reception year. The on‐entry assessment proved to be a good predictor of performance in reading and mathematics at the end of reception and the progress which each child made was estimated. This progress was found to vary considerably between schools and the variation was much greater than that typically found in school effectiveness studies. The data provided a unique opportunity to compare the progress of children who had, and had not, been to school. The Reception year was found to have had a major impact on the literacy and numeracy of children. Multi‐level models were employed for the analysis and from the models Effect Sizes were computed to assist in comparing the importance of variables in the study. This approach provides a mechanism for comparing the findings of school effectiveness studies with experimental studies and meta‐analyses. 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
