Stamatoula Pylarinou Sarantos Kapidakis 《Health information and libraries journal》2020,37(2):152-157
In this paper, Stamatoula Pylarinou with her supervisor Prof. Sarantos Kapidakis reports on an analysis of bibliographic data of the publications of Greek hospital personnel, conducted as part of Stamatoula’s doctoral research in the Department of Archive, Library and Museum Sciences at the Ionian University in Corfu, Greece. Using freely available data, they demonstrate the questions posed and the insights gained from the analysis of the scientific publications of personnel of public hospitals in Greece, in particular amid the years of austerity in Greece. With regard to impact on practice, they suggest that these procedures for the processing of medline /PubMed bibliographic data can improve communication among hospital librarians and administration or patients, adding value to their duties and enhancing the information and services they can provide.

The purpose of this study was to examine the impact factor of cognitive psychology journals indexed in the Science and Social Sciences edition of Journal Citation Reports (JCR) database over a period of 10 consecutive years. Cognitive psychology journals were indexed in 11 different subject categories of the database. Their mean impact factor ranged from 1.580 to 2.526. In relation to the subject categories of the Social Sciences edition, cognitive psychology journals were placed between the fourth and the sixth position for the years 2007–2009. Lower positions were observed in relation to the categories in the Science edition. Calculation of the intraclass correlation coefficient showed that cognitive psychology journals were relatively stable in the examined period. 相似文献

SciVerse is the new combined portal from Elsevier that services their ScienceDirect collection, SciTopics, and their Scopus database. Using SciVerse to access ScienceDirect is the specific focus of this review. Along with advanced keyword searching and citation searching options, SciVerse also incorporates a very useful image search feature. The aim seems to be not only to create an interface that provides broad functionality on par with other database search tools that many searchers use regularly but also to create an open platform that could be changed to respond effectively to the needs of customers. 相似文献
