    Abstract
    Die Publikationslandschaft der Erziehungswissenschaft ist durch eine enorme Breite undVielfalt sowie zahlreiche Verbindungen in benachbarte Felder gekennzeichnet. Aktuelle Analysen zum Publikationsverhalten von Erziehungswissenschaftlern zeigen, dass diese Hunderte von verschiedenen Zeitschriften und Verlagen zur Veröffentlichung nutzen. Um aus dieser Fülle an Publikationsorten die bedeutendsten zu ermitteln, wird ein neuer Ansatz zur Zeitschriftenbewertung, der "publication power approach" von Holsapple, auf die deutsche Erziehungswissenschaft übertragen. Dieser Ansatz basiert auf dem Publikationsverhalten von Forschern an ausgewählten Institutionen und stellt eine Alternative zu Expertenbefragungen und Zitationsanalysen dar. Der Beitrag stellt wesentlich Ergebnisse zur "publication power" von Zeitschriften und Verlagen der Erziehungswissenschaft vor und diskutiert Vor- und Nachteile dieses Ansatzes im Vergleich zu den herkömmlichen Bewertungsmethoden.

    Abstract
    Die Titel wissenschaftlicher Veröffentlichungen sind von besonderer Bedeutung. Wir haben fast 20 Millionen wissenschaftliche Artikel untersucht und den Anteil von Artikeln mit einem Fragezeichen am Ende des Titels im Laufe der letzten 40 Jahre analysiert. Unsere Studie beschränkte sich auf die Disziplinen Physik, Lebenswissenschaften und Medizin. Dabei haben wir eine deutliche Zunahme der Fragezeichen-Artikel von 50 Prozent auf mehr als 200 Prozent feststellten können. Vor diesem Hintergrund werden im vorliegenden Beitrag die grundsätzlichen Funktionen und Strukturen der Titel wissenschaftlicher Publikationen untersucht. Wir gehen davon aus, dass Marketing-Aspekte die entscheidenden Beweggründe sind für die zunehmende Nutzung von Fragezeichen-Titeln bei wissenschaftlichen Publikationen.
