• Researching Non-State Actors in International Security – Now Open Access

    The Routledge volume Researching Non-State Actors in International Security: Theory and Practice, edited by Andreas Kruck and Andrea Schneiker, has now been turned into a fully open access book. The book contains chapters on “interpreting texts” (Part I), “establishing causal claims” (Part II), and “doing fieldwork” (Part III). I contributed a chapter on “Qualitative Comparative Analysis and the Study of Non-State Actors” to Part II of the volume. The book’s substantive chapters are complemented by “discussion chapters” where commentators draw together and reflect upon the respective areas of research.

    Many thanks to the editors and other contributors for their efforts turning this into an open access book! I am grateful for the open access funding approved by the University of Erfurt to contribute to this aim.

  • QCA Faculty Workshop, University of Pennsylvania

    Qualitative Comparative Analysis: Research Design and Application

    On April 29-30, I taught a virtual workshop for 13 faculty members of the Perelman School of Medicine at the University of Pennsylvania, who are working on health-related applications of Qualitative Comparative Analysis. The intensive course followed the structure of my QCA textbook, which will be published with Georgetown University Press later this year (information about the book can be found here).

    Dating its foundation to 1740 with Benjamin Franklin as its first president, the University of Pennsylvania is a private Ivy League research university in Philadelphia, Pennsylvania. The Perelman School of Medicine is frequently ranked among the leading medical schools in the world.

    Thanks to everyone involved for turning this into a highly constructive two-day workshop experience!

  • Gastvortrag, Zeppelin Universität

    Am 22. April 2021 habe ich an der Zeppelin Universität am Lehrstuhl für Global Governance von Prof. Andrea Schneiker einen virtuellen Gastvortrag zum Thema “Democracy and War Involvement” gehalten. Nach einem Überblick zu Kriegsbeteiligungen westlicher Demokratien in den vergangenen Jahrzehnten lag der Schwerpunkt auf meiner vergleichenden Studie zum Abzug aus dem Irakkrieg, welche Bedingungen für den Abzug bzw. Verbleib westlicher Regierungen im Irak identifiziert (51 Regierungen aus 29 Demokratien im Zeitverlauf, 2003-2008).

    Herzlichen Dank an Prof. Andrea Schneiker und das Lehrstuhlteam für die Einladung und an die teilnehmenden Studierenden für die sehr engagierte Diskussion!

    Der Artikel im European Journal of International Security ist 2020 erschienen und frei verfügbar (open access). Eine Zusammenfassung findet sich im EJIS-Blog.

  • ISA Annual Convention 2021

    62nd Annual Convention of the International Studies Association, April 6-9, 2021

    At this year’s Annual Convention of the International Studies Association (ISA), I had four program appearances. The conference had initially been scheduled to take place in Las Vegas, but the COVID-19 pandemic made a shift to a virtual format necessary.

    Together with Eugénia da Conceição-Heldt, Omar Serrano Oswald, and Anna Novoselova, we presented a paper on “Survival and Resilience of the UN Joint Inspection Unit“, based on our DFG research project, in a panel on the “Persistence and Resilience of International Organizations”, chaired and discussed by Orfeo Fioretos. I further contributed to the “Foreign Policy Analysis Methods Café“, chaired by Falk Ostermann, and I took part in the roundtable “Qualitative Comparative Analysis in International Relations“, chaired by Tobias Ide. Finally, I also served as chair and discussant in the panel “Statecraft in the 21st Century” (for details on the panels and roundtables, see below).

    Besides these contributions, I also took part in the Business Meeting of ISA’s Foreign Policy Analysis Section and the Editorial Board Meeting of the section’s journal Foreign Policy Analysis (Oxford University Press).

    Overall, the virtual platform worked seamlessly and many of the panels were incredibly well-attended, with about 45 participants in the Methods Café and 30 participants in the panel on International Organizations. Nonetheless, the in-person interaction is surely missing, so let’s hope that next year’s ISA can take place as planned, in Nashville, Tennessee, March 2022!

  • QCA Textbook with Georgetown UP

    Georgetown University Press has finalized the cover for my forthcoming textbook Qualitative Comparative Analysis: An Introduction to Research Design and Application, to be published later this year. More information about the book can be found here.

  • QCA Workshop, University of Lausanne

    Qualitative Comparative Analysis (QCA)

    On January 14-15, I jointly co-taught a workshop on Qualitative Comparative Analysis (QCA) at the University of Lausanne, together with Benoît Rihoux of UC Louvain. Course participants were PhD students of the CUSO network of Western Switzerland (Universities of Lausanne, Fribourg, Genève, and Neuchâtel).

    Many thanks to the people at CUSO for the invitation and organization of the event and to the participants for a constructive workshop!

  • Summer School in Social Science Methods, Lugano 2021

    Qualitative Comparative Analysis at the 25th Summer School in Social Science Methods, 2021

    The workshop program was announced for the 25th Summer School in Social Science Methods, organized by the Swiss Foundation for Social Science Research (FORS) and the Università della Svizzera Italiana (USI). The school is hosted at USI in beautiful Lugano, Switzerland.

    For the third time, I am offering a one-week intensive course on Qualitative Comparative Analysis (QCA) at the Swiss Summer School. The course runs from August 23-27, 2021.

    The course is based on my QCA textbook Qualitative Comparative Analysis: An Introduction to Research Design and Application (Georgetown University Press).

    Course registration will open at the end of January/early February 2021. The opening will be announced through the summer school’s newsletter (sign-up on the registration page).

    Workshop contents

    This workshop gives a thorough introduction to the method of Qualitative Comparative Analysis (QCA), with an emphasis on research design and practical application. Since its inception (Ragin 1987), QCA has gained recognition among social scientists as a case-based research method that is ideally suited to capture causal complexity. This essentially describes a situation where an outcome results from multiple pathways and different combinations of conditions. Moreover, QCA entails a rigorous and systematic comparison of selected cases and their configurations through Boolean logic and a software-based analytical protocol.

    Throughout this workshop, participants will be introduced to the building blocks of QCA, while the course structure follows an ideal-typical research process. The introduction opens with empirical illustrations to show how and for what purposes QCA is being used, before summarizing the method’s key characteristics. This is followed by sessions on causation, causal complexity, and research design, to provide a foundation for thinking about empirical applications. The ensuing sessions engage with the use of QCA as an analytical approach, starting with set theory and concepts like necessary and sufficient conditions, Boolean algebra, truth tables, and fuzzy sets. In calibrating sets, we look into approaches to transform empirical raw data into crisp and fuzzy sets. Next, the course examines various measures of fit that help in evaluating QCA results. The session on set-theoretic analysis puts all of the elements together and shows how empirical data is analyzed and interpreted with QCA. Finally, the workshop closes with sessions on advanced topics, which can be tailored based on participants’ background and research interests. Potential topics include multi-method research design, QCA variants, addressing critiques, and recent developments. The workshop sessions are complemented by illustrations and exercises, using the R Software environment and relevant R Packages.
