肖谋文  姚春立  谢小龙 《山东体育学院学报》2006,22(1):3-5

通过对我国体育体制的结构分析，剖析了我国体育举国体制呈现的基本特点，认为举国体制的形成是因为资源不足和政治上的高度集权。随着社会的发展，举国体制的改革成为必然，但改革是渐进式的。在改革的过程中，要处理好政府和市场、体育系统内部与系统外部等几个方面的关系，并提出了一些探索性思考。  相似文献

采用文献资料和实证调查等研究方法,对我国体育新闻传播教育状况进行研究。认为:由于新闻事业和体育事业的迅猛发展以及国家教育政策的调整,使我国体育新闻传播专业办学规模不断扩大,呈现报考和招收人数持续上升与体育新闻传播专业教育“硬件不硬、软件太软”的矛盾。提出:应遵循体育新闻传播教育的办学规律,进一步整合资源,调整结构,加强软、硬件建设,提高教学质量,实现体育新闻传播教育的可持续发展。  相似文献   

The impact of digital technology on archival science     

Luciana Duranti 《Archival Science》2001,1(1):39-55

Archival science is to be regarded as a system. The properties of that system can be investigated and integrated. The methodology to do so has been tested in two research projects which are presented in this article as examples of the way in which the view of archival science as a system supports the development of new knowledge and as a demonstration of the stability of archival theory. This article presupposes that the archival discipline is also a “science”. Many have argued against the idea on the basis of a common perception that a science is a type of study entirely objective by virtue of the rigorous manner in which it is carried out and the restricted range of topics to which it applies. In fact, the activity of science is based upon a complex framework of assumptions that make it possible for the landscape of the scientific endeavour to be redrawn over time, and, while striving towards objectivity, considers it to be an unattainable ideal.  相似文献   

A Corpus-Based Learning Method of Compound Noun Indexing Rules for Korean     

Jee-Hyub Kim  Byung-Kwan Kwak  Seungwoo Lee  Geunbae Lee  Jong-Hyeok Lee 《Information Retrieval》2001,4(2):115-132

In Korean information retrieval, compound nouns play an important role in improving precision in search experiments. There are two major approaches to compound noun indexing in Korean: statistical and linguistic. Each method, however, has its own shortcomings, such as limitations when indexing diverse types of compound nouns, over-generation of compound nouns, and data sparseness in training. In this paper, we propose a corpus-based learning method, which can index diverse types of compound nouns using rules automatically extracted from a large corpus. The automatic learning method is more portable and requires less human effort, although it exhibits a performance level similar to the manual-linguistic approach. We also present a new filtering method to solve the problems of compound noun over-generation and data sparseness.  相似文献   

Measuring Search Engine Quality   总被引：12，自引：3，他引：9  

David Hawking  Nick Craswell  Peter Bailey  Kathleen Griffihs 《Information Retrieval》2001,4(1):33-59

The effectiveness of twenty public search engines is evaluated using TREC-inspired methods and a set of 54 queries taken from real Web search logs. The World Wide Web is taken as the test collection and a combination of crawler and text retrieval system is evaluated. The engines are compared on a range of measures derivable from binary relevance judgments of the first seven live results returned. Statistical testing reveals a significant difference between engines and high intercorrelations between measures. Surprisingly, given the dynamic nature of the Web and the time elapsed, there is also a high correlation between results of this study and a previous study by Gordon and Pathak. For nearly all engines, there is a gradual decline in precision at increasing cutoff after some initial fluctuation. Performance of the engines as a group is found to be inferior to the group of participants in the TREC-8 Large Web task, although the best engines approach the median of those systems. Shortcomings of current Web search evaluation methodology are identified and recommendations are made for future improvements. In particular, the present study and its predecessors deal with queries which are assumed to derive from a need to find a selection of documents relevant to a topic. By contrast, real Web search reflects a range of other information need types which require different judging and different measures.  相似文献

对近25年来中外体育概念研究的比较   总被引：20，自引：2，他引：18  

董杰 《体育与科学》2001,22(2):31-35

本文对中外近25年体育概念的研究进行了回顾与比较,将中外体育概念研究分为3个阶段.在不同的研究阶段,先后确立了体育是教育的组成部分,体育是文化的组成部分,人的发展与社会需要在体育中具有高度的一致性,从中发现体育的内涵不断扩大,人,成为体育概念研究的主体.值得借鉴的是,国外在对体育概念进行研究时,非常注重历史继承性和批判性,界定研究范围,具体情况具体对待,同时注意玩、游戏、娱乐、体育、竞技、运动和工作等之间的相互关系.  相似文献

伴随着经济一体化进程,我国竞技体育后备人才的培养受投资主体单一及竞赛制度的制约,各省市之间各自为政、封闭的后备人才培养体系效益较低。应该以国家“奥运战略”为目标,加强各省市体育后备人才培养合作,以发挥比较优势并提升整体竞争优势,为国家培养更多的高水平竞技体育后备人才。  相似文献
