This study analyzes publishing patterns of the staff of the University of Ibadan College of Medicine, Nigeria, based on a bibliography prepared by the authors. Data-gathering for the bibliography is described. An analysis is made of journals staff published in for the period 1961-1980, focusing on changes in journal order rank, publishing locations, and subject spread. A ranked list of the leading journals for the period 1976-1980 is given, showing the importance of local publishing and pointing to the need for local indexing.  相似文献   

运动员某些生理,生化指标的时间生物学特征探讨   总被引：1，自引：0，他引：1  

简坤林  周蓉晖 《成都体育学院学报》1995,21(1):91-96

对２６名男性运动员的环磷酸腺苷（ｃＡＭＰ）、环磷酸鸟苷（ｃＧＭＰ）、可的松（Ｃｏｒｔｉｓｏｌ）、睾丸酮（Ｔ）在２４小时内的不同时刻的量变的研究，以探讨其时间生物学特征，为运动员选材提供依据。结果发现ｃＡＭＰ、Ｃｏｒｔｉｓｏｌ、Ｔ均表现出明显的近似昼夜节律（Ｐ＜０．０５），ｃＧＭＰ不具有昼夜节律（Ｐ＞０．０５），ｃＡＭＰ的峰相位处于上午８时左右，Ｃｏｒｔｉｓｏｌ、Ｔ的峰相位与ｃＡＭＰ基本同步。可的松的节律稳定性好，可作为判定机能调整幅度的标志节律。  相似文献

Quality of grey literature in the open access era: Privilege and responsibility     

Paola?De?CastroEmail author  Sandra?Salinetti 《Publishing Research Quarterly》2004,20(1):4-12

Conclusions We are living a deep change in the information transfer process involving the different actors of the editorial scene (from authors to editors, web-editors, e-publishers and readers), who occasionally play different roles at the same time (e.g., authors sometimes bypass the editor thus assuming direct responsibilities in the diffusion of documents in the Internet). Furthermore, information producers, managers or seekers often show twofold personalities like Dr. Jekyll and Mr. Hyde. They would like to find all documents free on the Internet and be able to read original, reliable, and high quality information, but they are sometimes reluctant to spread their papers through online nonofficial channels as they care for the impact factor, prestige, and career advancement. It is a revolutionary period in which new and alternative forms of scholarly communication live together with more traditional ones and the future is difficult to define. Recent initiatives of open access—such as Pubmed Central, Public Library of Science, Budapest Open Access Initiative—are contributing to define new trends in the editorial market, challenging the traditional distribution channels, mainly managed by commercial editors, and placing the authors’ role and publication copyrights under severe discussion. In this landscape, GL now has new dignity and becomes closer and closer to innovative scientific publications supported by researchers in view of a generalised movement towards open access. The nuances of grey are becoming lighter and lighter. The questions are many, the answers few, but, in any case, the ethical responsibility of producing and issuing quality documents can never be disregarded.  相似文献   

Using a journal availability study to improve access     

Shaw-Kokot J  de la Varre C 《Bulletin of the Medical Library Association》2001,89(1):21-28

PURPOSE: Identify journal collection access and use factors. SETTING AND SUBJECTS: University of North Carolina at Chapel Hill's Health Sciences Library patrons. METHODOLOGY: Survey forms and user interactions were monitored once a week for twelve weeks during the fall 1997 semester. The project was based on a 1989 New Mexico State University study and used Kantor's Branching Analysis to measure responses. RESULT: 80% of reported sought journal articles were found successfully. Along with journal usage data, the library obtained demographic and behavioral information. DISCUSSION AND CONCLUSIONS: Journals are the library's most used resource and, even as more electronic journals are offered, print journals continue to make up the majority of the collection. Several factors highlighted the need to study journal availability. User groups indicated that finding journals was problematic, and internal statistics showed people requesting interlibrary loans for owned items. The study looked at success rates, time, and ease of finding journals. A variety of reasons contributed to not finding journals. While overall user reports indicated relatively high success rate and satisfaction, there were problems to be addressed. As the library proceeds in redesigning both the physical space and electronic presence, the collected data have provided valuable direction.  相似文献   

PubMed, Internet Grateful Med, and Ovid: a comparison of three MEDLINE Internet interfaces     

De Groote SL 《Medical reference services quarterly》2000,19(4):1-13

Three MEDLINE Internet interfaces are compared: PubMed, Internet Grateful Med, and Ovid MEDLINE. Although these interfaces all search MEDLINE, significant differences exist in terms of their search interfaces, presentation of results, and special features. This paper examines these variations and explores some of the advantages and disadvantages of the three interfaces.  相似文献   

Secondary-school students' motivation for portfolio reflection     

H.L. De Bruin  A.E. Oosterbaan  F.J. Prins 《Irish Educational Studies》2013,32(4):415-431

Several studies concluded that deep reflection is infrequently reached in student portfolios. An explanation for these disappointing conclusions might be that motivation for portfolio reflection determines the quality of reflection. This study aimed to examine the relationship between motivation for using digital portfolios and reflection. Participants were 156 eleventh-grade students in secondary education, whose motivation for composing a digital portfolio was measured by the motivation part of the Motivated Strategies for Learning Questionnaire. Portfolios of 37 of the 156 students were examined in terms of the amount and nature of reflection by means of a coding scheme based on Mezirow's model of transformative learning. On average, one-fifth (19.5%) of the paragraphs in a portfolio contained reflection, and paragraphs with deep reflection were hardly found (0.8%). It was concluded that motivation for composing a portfolio was fair, but not related to the amount and nature of reflection. This exploratory study gives rise to further research into factors that might influence the quality of portfolio reflection.  相似文献
