"武科应试器械"考论 总被引:1,自引:1,他引:0
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

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.

A discourse analysis of sports pedagogy regarding the pragmatic turn shows clearly that sports pedagogy has taken up ideas from other disciplines only in a coincidental or haphazard way. Genuine new forms of action or reflection were not recognized or did not show themselves in the discipline outside of common pedagogical discourses. Such resistance concerning concepts from other disciplines shows itself especially clearly in the turns following the pragmatic turn. Only where the “narrative turn” is concerned do we see traces of this discourse in sports pedagogy as well. However, these traces have already faded in the last 10 years. There are two reasons that sports pedagogy does not engage in discourse with other disciplines. Firstly, the obvious value of sport and physical exercise can make it seem unnecessary for sports pedagogy to meddle in the arguments of pedagogic worth experienced in other subjects. Secondly, the discipline still appears to be caught up in the mythology and terminology of German idealism. 相似文献

This article deals with the first years of foundation of the private Deutsche Hochschule für Leibesübungen (DHfL). It focuses on the question of why August Bier’s application for a Doktor der Leibesübungen in 1920 was refused. In the same year the DHfL also made an application for the education in state-run schools which was already task of the state-run Preußische Landesturnanstalt at Spandau. As the DHfL combined this application with its insistence on its autonomous status an application for a Doktor der Leibesübungen had implied financial, conceptual and institutional obligations for Prussia and at the same time a renuncitation of its sovereign rights. This thesis was proved by a comparison between the doctorate in physical education and the doctorate for businessmen at Cologne University. 相似文献
