Dr. Anamaria Dutceac Segesten, Associate Professor in Strategic Communication at Lund University, joins a discussion of cross-cutting expression and its implications for digital campaigning on Facebook.

Finally, we discuss what topic models of the Brexit debate around Facebook can reveal about how and what Facebook users discussed around the referendum. Links to the paper and supplementary material: Reconceptualizing Cross-Cutting Political Expression on Social Media: A Case Study of Facebook Comments During the 2016 Brexit Referendum (2023)Supplementary Material
