从体育文化角度对古代“武科”考试内容、应试器械等进行系统研究。结果显示:“武科”,又称“武举”,创立于唐武则天长安二年(702年),废于清末光绪二十七年(1901年8月29日),历经一千二百年。考试分外场(以长垛、马射、步射、刀术、枪术、翘关等体育项目为主)和内场(策论)。唐“武科”主要外场器械为弓箭,辅从刀、枪等。宋以弓箭刀枪为主同时将弩踏等作为考试项目。明代“武科”项目沿袭唐宋,外场器械未有变化。清代开始增加了“技勇”项目,分别为开硬弓、舞大刀、掇石。课题研究旨在为我国民族传统体育学的长足发展提供实质性的理论文献资料。  相似文献

Can constrained relevance feedback and display strategies help users retrieve items on mobile devices?

Searching online information resources using mobile devices is affected by small screens which can display only a fraction of ranked search results. In this paper we investigate whether the search effort can be reduced by means of a simple user feedback: for a screenful of search results the user is encouraged to indicate a single most relevant document. In our approach we exploit the fact that, for small display sizes and limited user actions, we can construct a user decision tree representing all possible outcomes of the user interaction with the system. Examining the trees we can compute an upper limit on relevance feedback performance. In this study we consider three standard feedback algorithms: Rocchio, Robertson/Sparck-Jones (RSJ) and a Bayesian algorithm. We evaluate them in conjunction with two strategies for presenting search results: a document ranking that attempts to maximize information gain from the user’s choices and the top-D ranked documents. Experimental results indicate that for RSJ feedback which involves an explicit feature selection policy, the greedy top-D display is more appropriate. For the other two algorithms, the exploratory display that maximizes information gain produces better results. We conducted a user study to compare the performance of the relevance feedback methods with real users and compare the results with the findings from the tree analysis. This comparison between the simulations and real user behaviour indicates that the Bayesian algorithm, coupled with the sampled display, is the most effective.

Combined individual scrummaging kinetics and muscular power predict competitive team scrum success     

Andrew Green  Chloe Dafkin  Samantha Kerr  Warrick McKinon 《European Journal of Sport Science》2017,17(8):994-1003

Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.  相似文献

A Peer‐tutoring Scheme to Support Independent Learning and Group Project Work in Mathematics     

Ken Houston 《Assessment & Evaluation in Higher Education》1996,21(3):251-266

A peer‐tutoring scheme was introduced to an undergraduate mathematics module. This was to provide a learning support for an independent learning programme. These student support groups also functioned as task groups for group project work. In the independent learning programme, students were directed to read selected passages of text, to attempt certain exercises and to devise peer assessment tasks. For some of the sessions senior students were present and functioned as additional peer tutors. To assess the students’ attitudes to the peer‐supported independent learning programme, an Attitudes to Peer‐tutoring Questionnaire was constructed. The results show that the students readily accepted the need to work in groups and to support one another. Overall, 78% felt that they could work easily without pressure and that the sessions were not a complete waste of time. However, 65% of the students did not appear to enjoy the independent learning sessions and felt that they preferred to be responsible only for their own learning.  相似文献
