Wissenschaftliche Umfragen können keine aussagekräftigen Ergebnisse liefern, wenn ihre Datenqualität durch fehlende oder verfälschte Antworten beeinträchtigt wird. Eine Herausforderung der Sozialforschung besteht darin, solche Fehlerquellen zu erkennen und zu kontrollieren. Der Band präsentiert Erkenntnisse und Methoden zur Behandlung von Unit Nonresponse, Missing Data und verschiedene Arten von Messfehlern im Kontext von Web und Mixed-Mode Panel, Mobile Web und Faceto-Face-Befragungen.

Religious texts of various literary genres reveal the transforming expressions of piety from medieval times to the early modern period.

The linguae& litterae series, edited by Peter Auer, Gesa von Essen and Werner Frick, documents the research activities of the School of Languageand Literature of the Freiburg Institute for Advanced Studies (FRIAS). These research activities in literary studies and linguistics are characterized by an approach that is theoretically and methodologically “state of the art” and interdisciplinarily open. In linguistics the accent is on the corpus-based, quantitative and qualitative investigation of language; in literary studies the focus is on the comparative, transdisciplinary analysis of literary phenomena in their cultural contexts. At the same time the series deals with the productive interfaces and synergies between modern linguistics and literary studies (as well as the humanities, social and natural sciences with which they interact). It seeks a new, contemporary reformulation of the humanities research curriculum and its problem and concept orientation for the future. The series has a clear international orientation - each volume is multilingual, containing German, English and French contributions and, depending on the volume, articles in Italian or Spanish as well. Each individual volume is peer reviewed by an international editorial board. Each year 2-4 volumes are published.

The series Texte und Textgeschichte [Texts and Textual History] set up by the Würzburg research group on ‘Medieval Prose’ under its leader Kurt Ruh contains editions and studies of widely disseminated high-impact late medieval German functional texts. They are prepared and presented with an emphasis on the communicative function of literature, the mutual interaction of author, writer and public. This involves taking primary account of textual mutations in the course of transmission; the methodological objective of each of the editions is to present these editorially in an optimum manner (textual transmission methodology). The studies are directed in each case at the particular circumstances of the transmission - textual geography, chronology and sociology - process the sources and trace the impact of the texts.
