- Abstract
- Purpose Public attitudes towards COVID-19 and social distancing are critical in reducing its spread. It is therefore important to understand public reactions and information dissemination in all major forms, including on social media. This article investigates important issues reflected on Twitter in the early stages of the public reaction to COVID-19. Design/methodology/approach A thematic analysis of the most retweeted English-language tweets mentioning COVID-19 during March 10-29, 2020. Findings The main themes identified for the 87 qualifying tweets accounting for 14 million retweets were: lockdown life; attitude towards social restrictions; politics; safety messages; people with COVID-19; support for key workers; work; and COVID-19 facts/news. Research limitations/implications Twitter played many positive roles, mainly through unofficial tweets. Users shared social distancing information, helped build support for social distancing, criticised government responses, expressed support for key workers and helped each other cope with social isolation. A few popular tweets not supporting social distancing show that government messages sometimes failed. Practical implications Public health campaigns in future may consider encouraging grass roots social web activity to support campaign goals. At a methodological level, analysing retweet counts emphasised politics and ignored practical implementation issues. Originality/value This is the first qualitative analysis of general COVID-19-related retweeting.

- Abstract
- Die Häufigkeit von Zitierungen wissenschaftlicher Publikationen kann in erster Näherung als Maßstab für ihre inhaltliche Qualität gelten. Die Journal Citation Reports (JCR) des ISI ordnen über die Auszählung von Referenzen aus mehreren tausend Fachzeitschriften durch diverse bibliometrische Indikatoren Zeitschriften einen bestimmten Wert zu. Der Aufbau der Datensammlung sowie die verwendeten Indikatoren werden näher beschrieben. 2 Methoden werden vorgestellt, mit denen in Anwendung der JCR eine Menge von Kernzeitschriften für ein Fachgebiet ermittelt werden kann. Probleme der Zuverlässigkeit bei der Sammlung und Verarbeitung der Zitierdaten durch die JCR werden dargestellt. Die Anwendbarkeit einer Zitatenanalyse für den Bestandsaufbau bei Fachzeitschriften wird untersucht. Sie kann zur Entscheidungsfindung beitragen, andere Methoden aber nicht ersetzen

- Blaise Cronin hat 2013 die Frage formuliert, ob es so etwas wie einen Kanon der Informationswissenschaft gibt. Er schlägt vor, zur Ermittlung des Kanons auch Namens- und Sachregister von einschlägigen Lehrbüchern informetrisch auszuwerten. Untersucht wurden englischsprachige Publikationen aus der Kategorie Information Science & Library Science der Fachdatenbank Web of Science sowie neun ausgewählte Lehrbücher der Informationswissenschaft. Im Web of Science wurden über 324.000 Publikationen ermittelt. Im Rahmen der szientometrischen Analyse wurden Zitationen, Publikationen und Themen ausgewertet. Zusätzlich zur klassischen Auswertung der Datenbankdokumente wurde erstmals eine Registeranalyse bei den Lehrbuchdokumenten durchgeführt. Die unterschiedlichen Ergebnisse wurden zusammengefasst, um einen gemeinsamen Kanon der Informationswissenschaft bilden zu können.

- Abstract
- Die Messung wissenschaftlicher Leistung hat gerade in Zeiten knapper öffentlicher Budgets Konjunktur. Wissenschaftliche Indikatoren zeichnen sich dadurch aus, dass nicht mehr einzelne Experten ihre subjektive Einschätzung über den Zustand der Wissenschaften abgeben, sondern die Summe dessen, was die Wissenschaft selbst produziert hat, so analysiert wird, dass ein objektives' Bild der Wissenschaft entsteht'. Zudem könnte mit der öffentlichen Diskussion etwa von Rankinglisten eine demokratische Steuerung des Wissenschaftsbetriebs erreicht zu werden'. Andererseits kann seriöse Forschung, die langfristige Forschungsziele in unspektakulären Schritten stützt, die unkonventionell Wissenschaft betreibt oder die Methodenkritik ernst nimmt, hierdurch benachteiligt werden. In unserer wissenschaftlichen Kommunikation wird es zunehmend schwerer, Wissenschaftsinhalte, Wissenschaftseinheiten und Wissenschaftsauswirkungen zu definieren oder gar ursächlich zuzuschreiben. Eine Bibliometrie, die sich als eine Wissenschaft von der Messbarkeit und Aussagekraft der wissenschaftlichen Prozesse und Produkte versteht, wird genau dort wieder anzusetzen haben, wo sie einst begonnen hat: nämlich bei der Hinterfragung dessen, wie Wissenschaftlichkeit und Forschungsfortschritt sich objektiv ausdrückt und wie dies 'unobstrusiv' ermittelt und sozialverträglich kommuniziert werden kann.

- Abstract
- Im vorliegenden Beitrag untersuchen wir die Beziehung zwischen Zitaten, Downloads und sog. Lesehäufigkeiten des sozialen Literaturverwaltungssystems "Mendeley" anhand der beiden Volkswirtschaftslehre-Zeitschriften "Journal of Environmental Economics and Management" und "Journal of Financial Economics". Trotz Ähnlichkeiten bei den Häufigkeitsverteilungen, konnten wir großteils nur mittlere (Rang)Korrelationen zwischen den drei Zeitschriftenindikatoren berechnen. In den drei Top-10 Rankings kam es zur Überschneidung von nur drei Publikationen. Deutliche Unterschiede gibt es bei den Alters- und Nutzerstrukturen. Während der Großteil der Mendeley-Nutzer Studierende sind, ist der Anteil der Professoren relativ gering. Durch die Mendeley-Profile kann ermittelt werden, aus welchen Disziplinen die Leser einer Zeitschrift kommen. Dies lässt vor allem bei interdisziplinären Zeitschriften wie "Journal of Financial Economics" interessante Rückschlüsse zu. Ähnlich wie bei Zitaten, gibt es auch bei Downloads und Lesehäufigkeiten disziplinspezifische Unterschiede.
