Abstract Purpose The purpose of this study is to modernize previous work on science overlay maps by updating the underlying citation matrix, generating new clusters of scientific disciplines, enhancing visualizations, and providing more accessible means for analysts to generate their own maps. Design/methodology/approach We use the combined set of 2015 Journal Citation Reports for the Science Citation Index (n of journals = 8,778) and the Social Sciences Citation Index (n = 3,212) for a total of 11,365 journals. The set of Web of Science Categories in the Science Citation Index and the Social Sciences Citation Index increased from 224 in 2010 to 227 in 2015. Using dedicated software, a matrix of 227 × 227 cells is generated on the basis of whole-number citation counting. We normalize this matrix using the cosine function. We first develop the citing-side, cosine-normalized map using 2015 data and VOSviewer visualization with default parameter values. A routine for making overlays on the basis of the map (“wc15.exe”) is available at http://www.leydesdorff.net/wc15/index.htm. Findings Findings appear in the form of visuals throughout the manuscript. In Figures 1–9 we provide basemaps of science and science overlay maps for a number of companies, universities, and technologies. Research limitations As Web of Science Categories change and/or are updated so is the need to update the routine we provide. Also, to apply the routine we provide users need access to the Web of Science. Practical implications Visualization of science overlay maps is now more accurate and true to the 2015 Journal Citation Reports than was the case with the previous version of the routine advanced in our paper. Originality/value The routine we advance allows users to visualize science overlay maps in VOSviewer using data from more recent Journal Citation Reports.

W artykule przeanalizowano publikacje polskich naukowców indeksowane w Social Sciences Citation Index. Wzięto pod uwagę wszystkie artykuły oraz artykuły przeglądowe z lat 2009-2015 (N = 6109) opublikowane w 1799 czasopismach. Każdemu czasopismu przyporządkowany został odpowiedni kwartyl Impact Factora na podstawie danych z Journal Citation Reports. Badanie pokazało, że polscy naukowcy publikują coraz więcej artykułów w czasopismach z części A „Wykazu czasopism punktowanych” i jednocześnie coraz częściej wybierają czasopisma z I lub II kwartyla Impact Factora.

The article explores bibliometric features of the Serbian psychology journal Psihologija in the 2001-2012 period. Several basic indicators of the journal?s impact were generated and compared between two periods, before and after 2007 when Psihologija was included in Social Sciences Citation Index (SSCI). Journal?s output was evaluated in regard to other psychology journals included in SSCI in the same year. The results have shown that Psihologija?s impact factor has raised following the increased internationalization of the journal, quantified as the proportion of articles published in English and/or written by foreign authors. However, Psihologija and other South East European (SEE) journals still lack a solid international communication network, which is reflected in the absence of related journals and large proportion of citations from local authors. The article concludes with several suggestions for authors, journal editors, and science policy institutions.

Zusammenfassung.Hintergrund: Die Häufigkeit pflegewissenschaftlicher Beiträge aus dem deutschsprachigen Raum in Zeitschriften mit hohem Impact Factor gibt Hinweise auf die Teilhabe der Disziplin am internationalen Diskurs. Bisherige Analysen beschränken sich auf pflegewissenschaftliche Zeitschriften. Diese konstatieren eine Unterrepräsentanz experimenteller Studien und klinischer Themen. Ziel: Identifikation und Analyse der Publikationen von im deutschsprachigen Raum ansässigen Pflegewissenschaftlerinnen/Pflegewissenschaftlern in internationalen pflegerelevanten High Impact Journals. Methode: Mittels Journal Citation Reports wurden pflegerelevante Zeitschriftenkategorien identifiziert, in denen die nach dem 5-Jahres-Impact-Factor höchsten 10 % der Zeitschriften der Jahre 2010 bis 2014 ausgewählt wurden. Der Einschluss der Publikationen und die Datenextraktion erfolgten durch zwei unabhängige Personen. Ergebnisse: Durchsucht wurden 106939 Publikationen aus 126 Zeitschriften. Eingeschlossen wurden 100 Publikationen, an denen 114 Pflegewissenschaftler/-innen aus dem deutschsprachigen Raum insgesamt 229 Mal beteiligt sind. Insgesamt 42 % sind Beobachtungsstudien, 11 % sind experimentelle Studien. Die berichteten Themen sind mehrheitlich klinisch orientiert (55 %). Über 50 % sind in den letzten zwei Jahren publiziert worden. Schlussfolgerungen: Das pflegewissenschaftliche Publikationsaufkommen aus dem deutschsprachigen Raum in High Impact Journals ist gering. Eine Zunahme über den Beobachtungszeitraum ist zu verzeichnen. Im Gegensatz zu früheren Analysen zeigt sich ein höherer Anteil klinischer Forschung.

The impact factor is a measure of the frequency with which the “average article” in a journal has been cited in a particular year or period (Journal Citation Reports; http://jcr.isihost.com). Specifically, it is the ratio of the number of articles from the journal cited over a given time period to the number of articles published by that journal during the same period. It is an objective measure of the journal’s importance, especially when compared to others in the same field. The purpose of the present study was to compare the impact factor of APAQ to 11 other journals in sport science, special education, and rehabilitation. The impact factor of APAQ compares quite favorably to most other journals in sport science, special education, and rehabilitation. However, it is strikingly different in 1998 and 1999, and therefore scholars should monitor it closely in the next few years while remembering it is only one estimate of journal prestige.

The 21st century has witnessed vast amounts of research into blended learning since the conception of online learning formed the possibility of blended learning in the early 1990s. The theme of this paper is blended learning in mainstream disciplinary communities. In particular, the paper reports on findings from the last two decades which looked at origination, development and future of blended learning through articles and other research publications. Based on over thirty journal articles indexed in Social Sciences Citation Index and other important databases, coupled with other related publications, this study explored the definition, advantages and problems of blended learning, arriving at the conclusion that more deficits may exist in either sole online or classroom learning compared with blended learning which combines both approaches although there may still be a certain number of disputes over blended learning. Educational and non-educational institutions may be wise to innovate their pedagogy towards a blended mode despite economic costs and other possible losses.
