New course on generative AI for behavioral science | Statistical Modeling, Causal Inference, and Social Science

A few people have asked for the syllabus from my grad seminar on Generative AI for social science -- just posted it here:

Just checked the raw survey responses to confirm β€”Β we simply got too few respondents in polisci!

Figure 2: Fields vary widely in their consensus around top-5 venues and the general alignment of their prefer- ences. Whether one uses a field-level ranking constructed from the pairwise comparisons of all respondents in a field to predict an individual’s pairwise comparisons (horizontal axis) or assesses the degree to which individuals in a field agree on a top-5 (vertical axis), some fields (e.g. Economics) demonstrate a much more overlapping and organized set of preferences than others (e.g. Computer science).

Academic fields differ in their degree of consensus about what "better" publication venues are β€” here shown both for consensus about the "top 5" and for pairwise choices.

For reasons related to #ICSSI2026, I logged into the equivalent account to @icssi.org over on X, and... wow, it really *is* substantially worse over there.

NSF Intent to Restructure Critical Weather Infrastructure

The US NSF has put out a "dear colleagues" letter that is essentially a yard sale list for @ncar-ucar.bsky.social

It asks questions such as, who'd like to take over some of NCAR's programs? Is anyone interested in commercial use of the Mesa Lab?

If you have thoughts, send them to NSF_NCAR@nsf.gov

And if I recall, Feynman was famous for intentionally doing such a bad job with service work that no one would ever ask him to do it again. So, that's a good sign, right?

You know that annoying NSF form "List every coauthor/co-PI from the last 4y" ?

At @cevianlabs.io we built a free tool that drafts the COI form from your PDF CV in minutes. Check it out πŸ‘‡

Loss of Infectivity of Influenza Virus and SARS-CoV-2 during Aerosol Sampling Our understanding of transmission of influenza virus and other respiratory viruses is limited by the difficulty of detecting infectious viruses in aerosol particles. Most aerosol sampling methods are believed to contribute to virus inactivation, but the magnitude of this sampling artifact is unknown. To investigate this question, we aerosolized influenza A virus (IAV) and SARS-CoV-2 suspended in human saliva into a small chamber (3.7 L). Aerosols settled for 10 min onto either cells or a thin layer of liquid medium that was immediately transferred to cells for plaque assay. Aerosols that deposited directly onto cells led to the formation of 100Γ— more plaque forming units (PFU) compared to aerosols that deposited first into liquid medium. Further experiments ruled out uneven aerosol distribution in the chamber or inefficient virus recovery as causes of this discrepancy. These findings indicate that aerosolized IAV and SARS-CoV-2 lost infectivity by approximately 2 log10 PFU within ∼10 min unless they attached to cells quickly. As natural infection via inhalation occurs by direct deposition of the virus onto cells, we hypothesize that sampling directly onto cells more accurately reflects the potential for exposure to lead to infection.

Our latest paper shows that most aerosol sampling methods may underestimate infectious virus in air. We observed 100x more infectious flu virus and SARS-CoV-2 if it deposited directly on cells (more realistic) rather than in liquid first and then transferred to cells. pubs.acs.org/doi/full/10....

We've alllllmost gotten all the Jan26 ARR reviews in, but I'm still trying to track down new emergency reviewers for papers on the following topics:
1) agents
2) jailbreaking
3) coding
4) RL
5) reasoning
6) LLM for finance
7) AMR
8) alignment
If you can review any (in next 24-48h) please DM me πŸ™πŸ™πŸ™
