"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.

Critical communication pedagogy and service learning in a mixed-method communication research course
ABSTRACTCourse: Mixed-Method Communication Research MethodsObjective: The purpose of this semester-long activity is to provide students with opportunities to cultivate mixed-method communication research skills through a social justice-informed service-learning format. Completing this course, students will be able to: recognize the unique strengths of quantitative and qualitative research methods; locate, evaluate, and utilize scholarly literature for a literature review; conduct an original research project using quantitative and qualitative research methods to gather and analyze data; and raise self and community awareness about a social issue through collaboration with a community organization. 相似文献

This study examined the skill involvements of three positional groups across a junior representative rugby league season. Data were collected from 45 rugby league players (mean ± SD; age = 16.5 ± 1.0 years) currently participating in the Harold Matthews and SG Ball Cup. Players were subdivided into hit-up forwards, adjustables and outside backs. The frequency (n · min?1) of offensive, defensive and overall involvements was coded for each group using a notation system and a practical coach skill analysis tool. Multivariate analysis of variance (MANOVA) revealed a significant effect of playing position on skill involvements (F = 9.06; P < 0.001; ES = 0.41). Hit-up forwards performed a significantly greater frequency of offensive (0.31 ± 0.10), defensive (0.42 ± 0.15) and overall involvements (0.74 ± 0.19) when compared to adjustables (0.20 ± 0.08, 0.28 ± 0.08 and 0.52 ± 0.15, respectively) and outside backs (0.20 ± 0.12, 0.11 ± 0.07 and ± 0.31 ± 0.17, respectively). Further, adjustables performed a significantly greater number of defensive (0.28 ± 0.08) and overall involvements (0.52 ± 0.15) when compared to outside backs (0.11 ± 0.07 and 0.31 ± 0.17, respectively). The findings of this study suggest that it is important to consider a junior player’s positional group when analysing their skill involvements. Information gained from this study could assist in the design of specific training methodologies for junior rugby league players in high-level talent development programmes. 相似文献

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
