That's definitely an interesting option, given all the great CSS research going on in the Baltics. We're taking our first baby steps at the moment, but this is surely something that we'll keep in mind as we consolidate the structure, and will bring up with the Society's members.

Our recent work (with Veronica Jude, @lajello.bsky.social, and @cerenbudak.bsky.social) on U.S. union Facebook messaging got featured by @poweratwork.bsky.social:

TikTok and the likes transformed how we spend time on our phones. But do they increase mobile use, or just reshuffle what we already do?

We find that adopting TikTok increases total mobile usage and shortens breaks from the phone.

Latest out: Fairness in infectious disease modeling. Great collaboration with Yuhan Li, @ngozzi.bsky.social @mtizzoni.bsky.social www.medrxiv.org/content/10.1...

New preprint: More is different for AI multi-agent systems - but what does more mean?

arxiv.org/abs/2510.22422

With @ariel-flint.bsky.social, @lajello.bsky.social and Romualdo Pastor-Satorras.

How does online communication adapt to organizational context?

In a new pre-print with @cerenbudak.bsky.social and @lajello.bsky.social, we study US labor unions’ Facebook use of discourse frames around wins and losses in representation elections. 🧵
