Very happy to have people from our @ldnsocmedobs.bsky.social attend the DSA40 Data Access Days organized by @dsa40collaboratory.bsky.social. With threats to our online and political safety in the rise, access to platform data for independent and academic researchers is more important than ever.
🇩🇪 Hello from Berlin!
📍This week, LSMO is at the #DSA40 Workshop, thanks @dsa40collaboratory.bsky.social for the invitation!
🤝 We’re here to connect with other academics to learn more about how to access platform data for research via DSA & to advocate for better data access more generally

🚨New Publication @thejop.bsky.social We study who sets the issue agenda of state policymakers in the US. We find a mixed picture: they respond to shifts in attention by members of Congress, but also to the constituents in their states, particularly their own party supporters.
Amid growing DC gridlock, state legislatures play a vital role in shaping policy. But how do state lawmakers decide which issues deserve their attention? Our new @thejop.bsky.social paper is the first large-scale multi-state analysis exploring this question

The courts ruled that X must urgently grant us access to their publicly available data via their API. This access is critical for our analysis of online public discourse ahead of the upcoming German elections.

Lots of voices are concerned about Elon Musk’s attempts to meddle in German and UK politics. The question is: what do people actually make of this? YouGov Germany has some recent data: In both, the public are assessing Musk’s interference negatively.
