This is very timely! We looked into the posting/moderation anomalies last week in the US. Special kudos to @benguinaudeau.bsky.social @solmg.bsky.social and @kengchichang.bsky.social. An outage rather than targeted censorship is what makes the most sense in this case, we’ll stay vigilant.

🌐 📲 With international collaborators, the Observatory’s director @andreucasas.bsky.social revisited recent “TikTok censorship” claims after the TikTok USDS takeover

➡️ Detailed information about the analysis available: goodauthority.org/news/was-the...

Was there censorship on TikTok after the U.S. takeover?
A TikTok outage more likely explains recent anomalies – there’s no evidence of larger platform changes so far.

The candidate will also have the opportunity to work in other international projects, with societal partners and policymakers, network with top scholars in the field, and the opportunity to teach in our department from the second year onwards.

Andreu Casas @andreucasas.bsky.social · Sep 29
The candidate will join a very exciting work environment, work side by side with me and the team in our central London location, and have access to funding for conferences, training, and data collection, on top of the stipend. Help me spread the word!

I hope I’m wrong and the UK government is still committed to transparency, academic access to tech/platform data, and independent/external scrutiny of the impact of these products on society. Time will tell I suppose. Meanwhile, we’ll keep advocating for what we think is right.

andreucasas.bsky.social
Andreu Casas @andreucasas.bsky.social · Sep 27
The Memorandum of Understanding from the UK government about the deal I fear confirms some of these suspicions, with language such as “advancing pro-innovation AI policy frameworks and efforts to support U.S. and UK-led AI technology adoption” (full memo here: lnkd.in/dw3NYvGz).

The US-UK tech deal last week left me worried. There was already a feeling the UK government was abandoning the idea of regulating tech companies/platforms, to facilitate trade deals with the US, incl legislation for better academic data access, and external scrutiny of tech products and platforms.

We went to Berlin this week to learn more from our peers about ways to leverage DSA to access platfrom data and conduct relevant research, and to keep building a coalition to advocate for this topic in the EU, the UK, and everywhere.

Andreu Casas @andreucasas.bsky.social · Sep 27
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

And as usual, the highlight of the week was to learn about the participants’ projects and to discuss with them how to take them to the next level. Here a few pictures from our traditional final session “Slides with Slices” 🍕 where participants presented the projects they worked on during the week.

Thanks @gesistraining.bsky.social for having me again. @marlenemauk.bsky.social @verenakunz.bsky.social and the team always make me feel at home in Mannheim for one week a year. Is Mannheim growing on me? 🤔

🥰I had so much fun again teaching computer vision and other computational methods to these bright social scientists this week. (Un)supervised classification, image encoding, content similarity, object detection, face detection/analysis, muldimodal modeling, video data, etc., you name it!

To junior scholars, the Observatory is the perfect home for computational social scientists to grow and shine! I’ll be soon recruiting a data engineer, PhD, and 2 postdocs, for our new offices in Bedford Square. To academics/orgs working in this area, we are eager to collaborate, please reach out!

Andreu Casas @andreucasas.bsky.social · Sep 16
Additionally, the Observatory will engage with key stakeholders in this area (@ofcom.bsky.social, @electoralcommission.org.uk, platforms, and others) to promote evidence-based policymaking in this area. Stay tuned for a first public event that we are putting together for the first week of December.

You'll be able to master all of these and more, with a combination of lectures, hands on sessions where code is provided, and with one-on-one consulting sessions. Students will also work on a project throughout the week. Bring your own data and project, and use that week to take it to the next level

Friday (11:20-13:00: 1A.12) Large Visual Language Models for Supervised Multimodal Classification in Political Science Research. We compare 2 VLMs to 6 other supervised classifiers (incl. LLMs: Llama2&3), across 2 datasets and 10 tasks. VLMs outperform all models across all tasks, w. some caveats.

Thursday (13:10-14:50: 1A.13): Moderation of Political Content on YouTube during the 2024 US Election. I tracked 20k channels and 6mil videos. Conservatives suspended more often, but also post most of hateful/misinfo. No difference in visibility, w. higher engagement for conservatives.
