This chapter discusses how performance is measured in science, such as through the role of citation metrics. Next, the chapter discusses the pros and cons of bibliometric indexes, and of ‘impact factor’, which was introduced by Eugene Garfield in 1955 but not widely used until twenty years later. The various ways that journals attempt to improve their impact factors, and how this will affect science, are also examined. Besides impact factor, the role played by indicators in evaluating scientists, such as the recently introduced h-index, is explored. Finally, fashions and trends in science are touched upon, illustrated with personal anecdotes from the author.

Citation Metrics

The idea that curiosity and discovery can be transcribed into rankings strikes at the very heart of science. The emerging norm of replacing scientific content with numbers is leading to an “impact factor syndrome,” whereby metrics influence both where interesting and important research is published and how committees evaluate scientists and science. This chapter discusses different citation metrics and why the scientific community increasingly looks to them as measures of impact.

Citation Metrics

Background: Despite exponential growth in Indian research, Indian journals have low impact factors. A previous study by one of the authors (CA) of this paper showed that articles published in the Indian Journal of Psychiatry (IJP) under-referenced previously published relevant papers in the same journal. Based on this, we decided to investigate the citation characteristics of contemporary scientific articles published in the Indian Journal of Psychological Medicine (IJPM). Methods: The citation characteristics of scientific articles published in 2018 (Vol 40, issues 1–6) in the IJPM were examined to determine how well the authors cited relevant articles published during the past ten years in the IJPM and the IJP. Results: There were 145 and 142 citation-worthy articles in the IJPM and the IJP, respectively; of these, 85.5% and 65.5%, respectively, had not been cited. Conclusions: Authors publishing in the IJPM under-reference previous relevant research published in the IJPM and IJP. This suggests unawareness of, deliberate disregard of, or even disdain for prior Indian research in the field. Additionally, if Indian researchers do not cite previous Indian research in the field published in Indian journals, the citation metrics of Indian journals will not grow.

AIM: To explore the global trends and focus of glaucoma research from 2009 to 2018. METHODS: Searching for glaucoma-related articles published in Science Citation Index Expanded (SCIE) database during 2009-2018, and describing the distribution of the published year, countries, authors, institutions, funding agencies, journals, impact factor, citation and hot research topic of articles by using bibliometric methods. Meanwhile, we compared some of these indicators over two five-year periods, from 2009 to 2013 and from 2014 to 2018. RESULTS: A total of 19 609 glaucoma-related articles were retrieved and the global SCIE articles have increased yearly from 2009 to 2018. The USA was the pioneer which has made great contributions. China kept the second place and the number of publications has increased rapidly between 2014 and 2018. The author with the highest number of publications was Weinreb, RN. Co-occurrence maps were built amongst the top 50 authors or the top 50 institutions with the most articles, which visualize the closer collaboration of international authors or institutions. The journal Investigative Ophthalmology & Visual Science has published the most papers. Glaucoma literature with an impact factor of 3-5 points accounted for the largest proportion (28.96%). The most frequently cited paper had 798 citations. The top three hot areas on glaucoma were intraocular pressure, optical coherence tomography (OCT) and retinal ganglion cells. And trabecular meshwork, primary angle-closure glaucoma and Spectral-domain OCT have become new hot research topics in recent five years during 2014-2018. CONCLUSION: Bibliometric analysis is an effective method to describe the global literature on glaucoma. In a 10-year literature survey from 2009 to 2018, global glaucoma research has developed in a balanced manner, and the cooperation between various institutions and teams has become closer. Glaucoma-related pathogenesis research, imaging examinations of OCT and surgery therapy have attracted most attention.

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.
