The objective of this guide is twofold. First, it shall enable interested readers to understand and reproduce the process of collecting author-specific citation metrics and publication data from the Thomson Reuters Web of Science and Scopus databases that is adopted in Andreoli-Versbach and...

A relevant question for the organization of large scale research assessments is whether bibliometric evaluation and informed peer review where reviewers know where the work was published, yield similar results. It would suggest, for instance, that less costly bibliometric evaluation might - at...

Die ökonomische Beurteilung von Vorgängen auf dem Arbeitsmarkt erfordert eine solide und aussagekräftige Datengrundlage. Eine Kerngröße zu deren Verständnis bilden Stundenlöhne. Stundenlöhne erklären beispielsweise, ob und in welchem Umfang Menschen arbeiten und konsumieren, warum und...
