Computational Conflict Research, a book co-edited with Jan Lorenz, Luis G. Nardin, Davide Natalini and Adalbert F.X. Wilhelm was just published in the series "Computational Social Sciences" at Springer Nature. It brings together a set of original studies that investigate conflict at various geographic scales and degrees of intensity and violence. Methodologically, it covers a variety of computational approaches from text mining and machine learning to agent-based modelling and social network analysis. Most of the contributions to the book resulted from research started at the first BIGSSS Computational Social Science Summer School that we organized at Jacobs University Bremen in 2018. The book is open acess and can be downloaded for free.
A new article, titled "Transnational Social Practices: A Quantitative Perspective", co-authored with Céline Teney, was just published in Emerging Trends in the Social and Behavioral Sciences. Transnational social practices (TSP) can be defined as sustained linkages and ongoing exchanges between individuals across national borders. Over the last decades, TSP have not only become more common, but they have also developed into an increasingly salient subject of quantitative sociological research. After highlighting seminal foundational research, we introduce a set of salient topics in this emerging strand of research, including the social stratification of TSP, the link between TSP and cosmopolitan attitudes, and the issue of classifying TSP into meaningful subdimensions. We conclude with a discussion of several avenues for future research, including the relation between TSP and the increasing societal polarization between “locals” and “globals,” the need to go beyond the field's current Eurocentrism to study TSP comparatively in all parts of the world, and the prospects of methodological and technical advances in research on TSP, including network‐analytic approaches and geo‐tagged digital‐trace data.

The paper "The Power of Contact: Europe as a Network of Transnational Attachment", coauthored with Jan Delhey, Monika Verbalyte, and Auke Aplowski, has just been published online first at the European Journal of Political Research. A free pre-print version is available here.
In this article, we propose transnational attachment as a novel indicator of sense of community in Europe, arguing that this hitherto neglected dimension is substantially and structurally different from alternative ones such as cross-border trust and identification. Combining Eurobarometer 73.3 data on ties between all EU-27 countries with further dyadic data, we show empirically that the European network of transnational attachment has an asymmetric core-periphery structure centered around five extremely popular countries (the UK, France, Germany, Italy, and Spain). In line with transactionalist theory, cross-border mobility and communication are strongly related to transnational attachment. Furthermore, we demonstrate that the network of transnational attachment is much denser among those with a higher than among those with a lower level of education. Our results suggest that offering European citizens incentives to travel to peripheral countries may help counterbalance the current asymmetric structure of transnational attachment, thereby increasing Europe’s social cohesion.
