- Abstract
- Die Karte stellt für die deutschen Universitäten und einige zu Vergleichszwecken ausgewählte außeruniversitäre Forschungseinrichtungen vier bibliometrische Kennzahlen auf Grundlage von zbMATH-Daten dar: Die Zahl der 2010 publizierten Arbeiten (links oben) und ihre gesamten zugehörigen Zitationen (links unten) sowie die Zahl der 2014 publizierten Arbeiten (rechts oben) und ihre gesamten zugehörigen Zitationen (rechts unten). Die Zusammenfassung auf Universitätsebene begründet sich damit, dass mathematische Arbeiten an einer Universität ggf. von Mitgliedern verschiedener Einrichtungen und/oder Fakultäten geschrieben werden. Die unterschiedliche Struktur der einzelnen Universitäten macht einen Vergleich von Einzeleinrichtungen sehr aufwändig. Zu beachten ist auch, dass die inhärente Fehlerquote sowohl bei der Zuordnung von Referenzstrings zu Arbeiten als auch von Arbeiten zu Autoren und Institutionen sich bei den Gesamtzahlen zu einer Abweichung von bis zu 20 % kumulieren kann. Die Jahre 2010 und 2014 wurden gewählt, da zum einen nach vier Jahren ein signifikanter Anteil der Zitationen relativ zum Publikationswachstum verfügbar ist (vgl. Abb. 4 auf S. 211), zum anderen für 2014 zumindest die Publikationsdaten einschließlich gedruckter Konferenzbände weitgehend vollständig erfasst sind (s. Anmerkung 2 auf Seite S. 213).

- Abstract
- The Matthew effect has that recognition is bestowed on researchers of already high repute. If recognition is measured by citations, this means that often-cited papers or authors are cited more often. I use the statistical theory of the growth of firms to test whether the fame of papers and authors indeed exhibits increasing returns to scale, and confirm this hypothesis for the 100 most prolific economists.

- Abstract
- Bibliometrische Daten werden heute zunehmend in der Evaluation von Forschungsergebnissen benutzt. Diese Anwendungen reichen von der (indirekten) Verwendung bei der Peer-Evaluation von Drittmittelanträgen über die Beurteilung von Bewerbungen in Berufungskommissionen oder Anträgen für Forschungszulagen bis hin zur systematischen Erhebung von forschungsorientierten Kennzahlen von Institutionen. Mit diesem Dokument will die DMV ihren Mitgliedern eine Diskussionsgrundlage zur Verwendung bibliometrischer Daten im Zusammenhang mit der Evaluation von Personen und Institutionen im Fachgebiet Mathematik zur Verfügung stellen, insbesondere auch im Vergleich zu anderen Fächern. Am Ende des Texts befindet sich ein Glossar, in dem die wichtigsten Begriffe kurz erläutert werden.

- Abstract
- Presents a quantitative anaylsis of 100 references retrieved on the information use and needs of humanities researchers, consisting of journal articles (57%), dissertations (26%), conference proceedings (11%) and books (6%). 3 journal titles were found to contribute more than a third of the articles on this subject. About 88% (23) of the dissertations are doctoral theses submitted to universities in the USA. about 51% of the retrieved items were published between 1980-1989 which form the peak of studies in this area and the situation stabilizes to an average of about 2 studies a year in the post 1990 years. The bulk of the studies is about characteirstics of information sources used and of these citation studies are predominant. Information needs and use in the field of literature, history and music (62%, 41) constitute the majority of studies in this area. The review studies come under 3 categories; the library and humanities scholars; research and information seeking behaviour of the humanities researchers and the characteristics of sources used

- Abstract
- Counts of tweets and Mendeley user libraries have been proposed as altmetric alternatives to citation counts for the impact assessment of articles. Although both have been investigated to discover whether they correlate with article citations, it is not known whether users tend to tweet or save (in Mendeley) the same kinds of articles that they cite. In response, this article compares pairs of articles that are tweeted, saved to a Mendeley library, or cited by the same user, but possibly a different user for each source. The study analyzes 1,131,318 articles published in 2012, with minimum tweeted (10), saved to Mendeley (100), and cited (10) thresholds. The results show surprisingly minor overall overlaps between the three phenomena. The importance of journals for Twitter and the presence of many bots at different levels of activity suggest that this site has little value for impact altmetrics. The moderate differences between patterns of saving and citation suggest that Mendeley can be used for some types of impact assessments, but sensitivity is needed for underlying differences.

- Abstract
- In einer industriellen IuD-Stelle konnte auf der Basis vorhandener Langzeitstatistiken die funktionale Abhängigkeit der Literaturnutzung vom Alter der Literatur - in Form von Kopien aus Fachzeitschriften und von SAE-Berichten - mathematisch beschrieben und für die Praxis anwendbar gemacht werden. Grundlagen und Ermittlung der Basisdaten, deren Aufbereitung für eine mathematische Verarbeitung und ihre Darstellung als logarithmische Funktion werden erläutert. Die aus der Regelungstechnik bekannte Sprungantwortfunktion ist von der Sache her anwendbar und beschreibt das Phänomen plausibel. Die für ausgewählte Jahrgänge der betrachteten Literaturarten gefundenen Gleichungen werden in ihren Parametern diskutiert. Anhand der Resultate der Arbeit ergibt sich die Möglichkeit, eine Alterungskurve mit nur einer Zählung (statt der drei mathematisch erforderlichen) abzuschätzen. Ein Vergleich mit derBestimmung der Alterung der Nutzung auf der Basis der Zitatenanalyse zeigt, dass beide Verfahren kompatibel sind.
