Usage Comparison between an English-Language and a French-Language E-Monograph Collection in a Bilingual Canadian University     

Alain R. Lamothe 《International Information and Library Review》2020,52(2):139-160

Abstract

This article reports the results of a quantitative and systematic analysis comparing usage rates between English-language and French-language e-monograph titles at Laurentian University, Canada. Full-text viewings were collected as usage metrics. English-language e-monographs exhibited medium strength linear relationships between collection size and usage. On the other hand, French-language e-monographs exhibited weak linear relationships between collection size and usage. The French-language e-monograph collection experienced a higher rate of full-text use, relative to size. The cost-per-viewing ratio for the English-language e-monograph collection was higher than those that calculated for the French-language collection.  相似文献   

上海市技术比较优势及其演变分析——基于上海市职务发明专利申请的统计分析   总被引：1，自引：0，他引：1  

俞文华  张俊燕 《中国青年科技》2007,(11):6-16

上海市是我国发明专利申请最活跃和技术创新能力最强的城市之一,充分发挥其技术比较优势,不仅有利于其进一步提升技术创新能力,而且也有利于其代表我国在全球科技竞争中占据制高点。本文在对上海职务发明专利申请进行分技术领域统计的基础上,首先对上海职务发明专利申请态势、技术领域分布及其在全国中的地位进行了分析,其次根据其不同技术领域的显性技术比较优势指数,对其技术比较优势及演变进行了研究,最后对上述分析结果的公共政策含义进行了初步探讨。  相似文献   

Subspace design of low-rank estimators for higher-order statistics     

Ivan Bradaric  Athina P. Petropulu  Konstantinos I. Diamantaras 《Journal of The Franklin Institute》2002,339(2):161-187

Higher-order statistics (HOS) are well known for their robustness to additive Gaussian noise and ability to preserve phase. HOS estimates, on the other hand, have been criticized for high complexity and the need for long data in order to maintain small variance. Since rank reduction offers a general principle for reduction of estimator variance and complexity, we consider the problem of designing low-rank estimators for HOS. We propose three methods for choosing the transformation matrix that reduces the mean-square error (MSE) associated with the low-rank HOS estimates. We also demonstrate the advantages of using low-rank third-order moment estimates for blind system estimation. Results indicate that the full rank MSE corresponding to some data length N can be attained by a low-rank estimator corresponding to a length significantly smaller than N.  相似文献

国内外信息行为博硕论文比较研究     

田丽丽  刘竟 《现代情报》2016,36(12):120-125

以信息行为领域的114篇国内博硕论文和124篇国外博硕论文为样本,从基本情况（学位层次、发表时间、所属机构、学科分布）、信息行为的主体和客体、信息行为的类型、高频关键词、研究方法、研究深度6个方面进行国内外比较研究。结果发现,国内外共同点主要有3点：信息行为主体、客体的广泛性和多样化;相对于其它类型的信息行为而言,信息搜寻行为研究占主导地位;总频次位于前3位的研究方法是调查法、统计分析法和访谈法。国内外主要不同之处在于学位层次、学科分布、信息行为的主体和客体类型、研究深度方面存在差异。最后,对国内未来有志于从事信息行为研究的博硕士研究生提出5条研究建议。  相似文献

The information seeking behaviour of the users of digital scholarly journals     

David Nicholas  Paul Huntington  Hamid R. Jamali  Anthony Watkinson 《Information processing & management》2006

The article employs deep log analysis (DLA) techniques, a more sophisticated form of transaction log analysis, to demonstrate what usage data can disclose about information seeking behaviour of virtual scholars – academics, and researchers. DLA works with the raw server log data, not the processed, pre-defined and selective data provided by journal publishers. It can generate types of analysis that are not generally available via proprietary web logging software because the software filters out relevant data and makes unhelpful assumptions about the meaning of the data. DLA also enables usage data to be associated with search/navigational and/or user demographic data, hence the name ‘deep’. In this connection the usage of two digital journal libraries, those of EmeraldInsight, and Blackwell Synergy are investigated. The information seeking behaviour of nearly three million users is analyzed in respect to the extent to which they penetrate the site, the number of visits made, as well as the type of items and content they view. The users are broken down by occupation, place of work, type of subscriber (“Big Deal”, non-subscriber, etc.), geographical location, type of university (old and new), referrer link used, and number of items viewed in a session.  相似文献
