This study examined the occurrence of color in dissertations and theses produced at the Pennsylvania State University over a nine year period. Since the most common preservation method for dissertations and theses is monochromatic microfilming, traditional treatment may result in a loss of information encoded in color in these resources. Results indicate a significant increase in the use of color over the time period studied. Variations in the amount of color use by discipline were also observed. Implications related to monochromatic microfilming and recommendations for long term preservation are discussed.  相似文献

以儿科、外科、内科、放射、口腔5个学科发文最多的10位专家为研究对象,对这些高产作者在中文期刊和SCI期刊发表论文的情况进行对比分析。数据显示:1)2000—2012年,本研究的目标作者在SCI收录期刊发表论文的数量低于万方数据库,国内科学领域主要的学术交流平台仍是中文期刊。2)目标作者在SCI收录期刊发表论文呈逐年上升趋势,而我国的中文期刊发表的论文,在2006年进入平台期,随后呈下降趋势。2012年,5个学科SCI论文与中文期刊论文篇数基本相等。3)目标作者的SCI论文的被引频次中37.96%为国内作者引用。4)与中国科技论文外流整体情况比较,医学优秀论文外流更为严重。  相似文献

林业类科技核心期刊文献引用研究   总被引:1,自引:0,他引:1  
为全面、深入分析文献引用对林业类科技核心期刊质量的影响,通过资料分析,采用数理统计方法,选择同一层次的5家林业类科技核心期刊,对其2014年全年的参考文献的引用情况(篇均引文量、引文类型、引文语种、引文的时效性、期刊自引率)进行统计和分析.结果表明:5家期刊参考文献的引用情况不尽相同,篇均引文量需要提高;参考文献来源类型主要是期刊;语种以中文为主,其次是英文,其他语种引用比较少;参考文献时效性和期刊自引率控制较为合理,但有提升空间.通过统计数据分析,希望期刊编辑重视刊发文章引文的各项指标,从而提高刊发文章质量.  相似文献

Given the thousands of theses and dissertations (TDs) that are produced each year, and their role in advancing their disciplines, it is well worth disseminating them as widely as possible. A great leap forward in increasing TD distribution has been the electronic theses and dissertations (ETDs) movement. ETD information in catalogs provides valuable basic access, especially when bibliographic records are contributed to large databases. While these bibliographic records can be created automatically by harvesting author-supplied metadata from ETDs, for fuller access, cataloger mediation is needed to remove errors and numeric entities; plus name authority control. Fullest access entails subject analysis.  相似文献

分析博硕士学位论文的上网入库和再发表牵涉到的一系列相关问题。认为:根据《著作权法》对公开发表的界定,博硕士论文答辩后的缴存或者商业性开发是公开发表,但是对博硕士论文的合理使用以及授权并不是出版,其再发表不适用"一次用尽"原则;博硕士研究生应积极配合公益缴存以及合法机构的商业性开发;为充分发挥博硕士学位论文的学术价值,应鼓励其再发表。  相似文献

This study investigates the decay and half-life of online citations cited in four open access journals published between 2000 and 2009. A total of 1158 online citations cited in 1086 research articles published in two science and social science journals spanning a period of 10 years (2000–2009) were extracted. Study found that 24.58% (267 out of 1086) of articles had online citations and these articles contained a substantially very less number of online citations (2.98%) compared to previous study results. 30.56% (26% in Science and 52.73% in Social Science) of online citations were not accessible and remaining 69.44% of online citations were still accessible. The ‘HTTP 404 error message-page not found’ was the overwhelming message encountered and represented 67.79% of all HTTP message. Domains associated with .ac and .net had higher successful access rates while .org and .com/.co had lowest successful access rates. The half-life of online citations was computed to be approximately 11.5 years and 9.07 years in Science and Social science journal articles respectively.  相似文献

This paper evaluates the status of digitization in 30 Nigerian university libraries with a view to identifying the status, progress, prospects and challenges to digitize library materials and form the basis of providing a roadmap to successful execution of digitization projects. The study assessed the status of digitization of past question papers, theses and dissertations in Nigerian university libraries from May to September 2006 through a self-administered questionnaire, site visits and interviews. It was found that, though there are automation services in those universities, there is no digitization of these materials mentioned in the surveyed institutions. The major obstacles militating against digitizing in the university libraries include lack of funds, lack of appropriate facilities, lack of skilled manpower and lack of constant electricity supply. Respondents were anxious to have the services to commence because of their importance in facilitating teaching, learning and research.  相似文献

Using 17 open-access journals published without interruption between 2000 and 2004 in the field of library and information science, this study compares the pattern of cited/citing hyperlinked references of Web-based scholarly electronic articles under various citation ranges in terms of language, file format, source and top-level domain. While the patterns of cited references were manually examined by counting the live hyperlinked-cited references, the patterns of citing references were examined by using the cited by tag in Google Scholar. The analysis indicates that although language, top-level domain, and file format of citations did not differ significantly for articles under different citation ranges, sources of citation differed significantly for articles in different citation ranges. Articles with fewer citations mostly cite less-scholarly sources such as Web pages, whereas articles with a higher number of citations mostly cite scholarly sources such as journal articles, etc. The findings suggest that 8 out of 17 OA journals in LIS have significant research impact in the scholarly communication process.  相似文献
