Introduction
I am a postdoctoral research and teaching assistant at the division of media psychology and effects. From 2009 to 2017 I was engaged in the NCCRdemocracy, overseeing quantitative content analyses and linkage studies investigating the effect of media content on citizens. In this project, a series of tools for computer-assisted content analyses were developed. In a second tier of my research, I focus on computational social science and the development and application of novel methods to tackle a wide variety of data. These projects include (but are not limited to) automated content analyses, agent-based modeling, simulation studies, pattern detection and noise reduction in complex data, seqence and cluster analysis, and data management.

Article
Linkage analyses use data from panel surveys and content analyses to assess media effects under field conditions and are able to close the gap between experimental and survey-based media effects research. Results from current studies and simulations indicate, however, that these studies systematically under-estimate real media effects as they aggre...
Preprint
The study explores how news messages carrying parts of the populist ideology contribute to a polarization of public opinion about populism. It combines a content analysis of news coverage on two policy areas (N = 7,119 stories) with a two-wave panel survey (N = 2,338) in four European metropolitan regions (Berlin, Paris, London, Zurich). In three r...
Chapter
This volume assembles a wide range of perspectives on populism and the media, bringing together various disciplinary and theoretical approaches, authors and examples from different continents and a wide range of topical issues. The chapters discuss the contexts of populist communication, communication by populist actors, different types of populist...
Article
Right-wing populism has a long tradition in Switzerland. Nevertheless, only little is known about how populist messages in the media contribute to the success of the Swiss People’s Party (SVP) and to the acceptance of the party’s anti-immigration policies. In this study, we combine data from a large media content analysis (including newspapers and...
Chapter
Die Kommunikationswissenschaft hat zunehmend Zugriff auf umfangreiche und feingliedrige Beobachtungsdaten, mit denen unter an- derem Prozesse der Mediennutzung, -rezeption und -wirkung beschrieben werden. Neue Erhebungsmethoden erlauben es etwa, das Online-Verhalten von MediennutzerInnen (z. B. die Kommunikation auf Twitter), die phy- siologischen...
Article
Full-text available
In various branches of the social sciences, agent-based models (ABMs) have long been applied to enhance researchers’ understanding of complex systems and processes. However, in communication science, this approach is rarely used. In this article, we argue that ABMs have the potential to advance communication research in general, and computational c...
Article
The rising voter support for populist parties in Western Democracies in recent years has incited academic interest in populist voters and attitudes connected to the voting propensity of populist actors. In line of this research, numerous scales to measure populist attitudes among voters have been proposed. In most cases, however, the measurement of...

Article
Full-text available
The success of populist political actors in Western democracies and the dramatization and emotionality of political communication in news media have been the object of several theoretical and empirical studies in the past decade. It has been argued that the mediatization of politics and the convergence of populist and tabloid communication styles f...
Article
The persuasiveness of right-wing populist communication has become a widely discussed topic; it is often assumed that such messages might foster anti-immigrant attitudes among citizens. The present study explores the effects of the different components of right-wing populist communication—anti-immigrant messages, populist content, and populist styl...
Article
Full-text available
In the wake of the recent successes of populist political actors and discussions about its causes in Europe, the contribution of the media has become an issue of public debate. We identify three roles—as gatekeepers, interpreters, and initiators—the media can assume in their coverage of populist actors, populist ideology, and populist communication...

Full-text available
Ein Teil des Erfolgs populistischer Bewegungen ist ihrer Kommunikation und Präsenz in den Medien geschuldet. Journalist_ innen geben populistischen Akteuren nicht nur eine Bühne für ihre Themen, sondern schließen sie zum Teil vom politischen Diskurs aus oder kritisieren sie stärker als andere politische Akteure. Genauso können Massenmedien auch zu...
Presentation
Full-text available
In recent years, communication scholars from different fields have been proposing many new theoretical and empirical models concerning reinforcing spirals in media use, effects, and content. The statistical models used to test these theories are, however, far from consensual to date and leave researchers with a plethora of decisions in their config...

In the wake of the recent success of populist political actors and causes in Europe, the role of the media in the promotion of populism has become an issue of public debate. We understand populism as a thin ideology that is articulated discursively by political and media actors and focus on two ideational constituents of media populism, namely ‘peo...

Full-text available
In empirical linkage analyses, panel surveys are linked to parallel media content analyses to explain opinion dynamics by media effects on individuals. In these analyses, however, media content is temporally aggregated and complex short-term reactions to media and the social environment are not taken into account. In this study, we perform a linkag...
Article
Full-text available
Theoretically, populism has been conceptualized as a political ideology with three sub-dimensions: anti-elitism attitudes, a preference for popular sovereignty, and a belief in the homogeneity and virtuousness of the people. However, empirical research to date has treated populist attitudes as a unidimensional construct. To address this issue, we p...

Article
In their daily routine, all citizens partake, albeit not always consciously, in mass communication. This communication takes place in various channels, such as newspapers, magazines, television, billboards, and social media sites. It even occurs indirectly via discussions with other media users. Extensive research over the past decades has shown th...

Die zunehmende Vernetzung über Soziale Netzwerkdienste (SND) bringt neue Formen der politischen Partizipation mit sich. So wurden in vergangenen Jahren Facebook-Gruppen (FG) von Protestgruppen und Interessensgemeinschaften verwendet, um zu mobilisieren und Diskussionen anzuregen. In diesem Artikel werden politische FG anhand eines konkreten Falles...

Der Umgangston in den Kommentar-Threads von Online-Medien und Facebook-Seiten weist nur selten auf einen konstruktiven und offenen Diskurs hin. Viele Diskussionen werden von aggressiven, beleidigenden oder extremistischen Kommentaren gestört und Benutzer werden persönlich angegriffen. Eine aktuelle parlamentarische Enquete in Österreich befasst sic...
Thesis
Die manuelle Inhaltsanalyse ist trotz der fortschreitenden Digitalisierung auch heute noch die zentrale Erhebungsmethode in der Kommunikationswissenschaft. Obschon automatische Verfahren günstiger und effizienter wären, wird nur ungern auf die Lesekompetenz und Verlässlichkeit menschlicher Codierer verzichtet. Während diese Entscheidung in vielen F...

Chapter
Werden Texte detailliert inhaltsanalytisch untersucht, um beispielsweise die Rolle von Akteuren im Wahlkampf oder den semantischen Gehalt einer Debatte zu erfassen, so steht der Forscher häufig vor dem Problem, innerhalb einer Analyseeinheit (z.B. dem Text als Ganzes) mehrere getrennt zu erhebende Analyseeinheiten (z.B. Akteure oder Argumente) erhe...
Chapter
Die Methode der Inhaltsanalyse als zentrale Erhebungsmethode in der Kommunikationswissenschaft ist umfassend dokumentiert, z. B. bei Merten (1995), Früh (2001) oder Rössler (2010), im anglo-amerikanischen Sprachraum Krippendorff (2009) oder Neuendorf (2010). Beschrieben werden besonders Aspekte der Projektplanung, der Codebucherstellung sowie Ablau...
Article
Media coverage of public debates has been shown to exhibit long phases of reduced media attention which are eventually interrupted by sudden attention bursts. These attention bursts increase the salience and perceived importance of an issue in the public and may exert an influence on political decisions. Therefore, the question for the causes of th...
Book
Die Inhaltsanalyse ist für die Kommunikationswissenschaft die genuine Erhebungsmethode. Nur inhalts­analytisch lassen sich Medieninhalte empirisch erfassen und analysieren und nur inhaltsanalytisch kann demnach eine Antwort auf die Frage gefunden werden, mit welchen potenziell beeinflussenden Inhalten der Rezipient, überhaupt in Kontakt kommt. Mit...
Chapter
Die schnell wachsende Verfügbarkeit von elektronischen Texten, seien dies digitale Ausgaben von Zeitungen, Formen nutzergenerierter Inhalte in Online-Medien oder Textnachrichten in sozialen Netzwerkdiensten, führten in den letzten Jahren zu intensiven Bemühungen, Verfahren der computergestützten Inhaltsanalyse für diverse Fragestellungen der Kommun...
Conference Paper
Die Medienwirkungsforschung arbeitet mit einer Reihe von Theorien, welche beobachtete Effekte als emergente Ergebnisse einer Reihe unbeobachteter Einzelschritte beschreiben. So werden in der Unterhaltungsforschung kontinuierliche Appraisals während der Rezeption eines Films für die Entstehung von Unterhaltung verantwortlich gemacht (Wünsch 2006), d...

Conference Paper
Full-text available
Most online news media today enable and encourage their readers to comment on published content and discuss covered issues. Spontaneous discussions on these platforms among anonymous and intrinsically involved citizens have a high potential for public deliberation. This potential, however, may be lowered in practice by the behavior of the discussan...
Conference Paper
Eine der zentralen Fragestellungen in der Kommunikationswissenschaftlichen Forschung ist: "Wie berichten die Medien über das Thema XY?". Diese Frage ist sowohl direkt für die Erforschung der Medienrealität, als auch indirekt für die Medienwirkungsforschung (in Zusammenhang mit Befra-gungsdaten), für die politische Kommunikatorforschung (im Zusammen...
Conference Paper
The study investigates the quality of media debates on unemployment in six European countries – Germany, the United Kingdom, France, Italy, Switzerland, and Denmark. Because there exist different normative conceptions of the democratic process (e.g., liberal and deliberative theories), the quality of media debates can be measured according to diffe...
Conference Paper
Full-text available
In the analysis of communication events such as elections, public debates, business communication or campaigns, contingency analyses have become a widely used tool in recent years. By means of analysis of co-occurrence patterns of words, objects or broader semantic elements, the contents of complex communication events may be summarized to few sub-...
Chapter
Standards werden unter anderem auch in der komparativen (auch kulturvergleichenden) Forschung diskutiert. In diesem speziell auf den Vergleich zwischen Nationen oder Kulturen ausgerichteten Forschungszweig wird ein Problem virulent, das zumindest implizit nahezu jeder Art von empirischer Forschung zugrunde liegt1: Inwiefern sind die Resultate solch...
Article
Answering the call for nonexperimental framing effects research, this article analyzes the effects of news frames on citizens’ political cognitions using data derived from a campaign on the naturalization of immigrants. A content analysis of TV and newspaper coverage was combined at the individual level with answers to open- and closed-ended panel...

Die Vorbereitung von Inhaltsanalysen, Befragungen und Experimenten, bei denen ein bestimmter thematischer Fouks gewählt wird, bedürfen einer Auseinandersetzung mit dem Inhalt des gewählten Themas in der öffentlichen Diskussion, um relevante Themenbereiche, Akteure und Entwicklungen zu erkennen und bei der Erstellung des Instruments oder Stimulus’ b...
Chapter
Trotz seines theoretisch vorhandenen Potentials zur Förderung der Demokratie schien das Internet in den letzten Jahren gerade die jugendlichen Nutzer immer weiter von der Politik zu entfernen. Sie wurden als desinteressiert, apathisch oder politikverdrossen bezeichnet und Befragungen wiesen auf eine sinkende politische Partizipation, online wie off...
