Spencer Foundation joins Kapor Foundation, the William T. Grant Foundation, and the Alfred P. Sloan Foundation to launch a rapid response bridge funding program (up to $25,000) for education scholars impacted by the abrupt grant cancellations by the National Science Foundation (NSF)! #AcademicSky

Rapid Response Bridge Funding Program

In the face of recent abrupt shifts in federal funding for education research, including large-scale terminations of National Science Foundation (NSF) research grant awards, we have developed a rap...

We’re hiring postdocs to join my lab at UNC. If you’re interested in adolescence, brain, and social development, DM me. Our work incorporates fMRI, social media, and longitudinal methods. We study risks and opportunities in adolescence. If you’re at #SRCD2025 and want to meet, please reach out!

My dear health equity peers, the Robert Wood Johnson Foundation is doubling down on their DEI efforts. 💪🏽 Here’s a grant opportunity tinyurl.com/3pnxhy2d with a rapid response option those whose “health equity research projects have lost federal funding.” ⭐️ Please share ⭐️

Research to Advance Racial and Indigenous Health Equity

504 plans are how kids can carry EpiPens or make sure their classroom is peanut free. It’s how kids with diabetes can use insulin. It’s how kids with mobility issues can have more passing time or use an elevator. An attack on 504 is an attack on everyone. Listen to @lollardfish.bsky.social.

NEW: On Section 504. "Attacks on any one group will be used as a wedge to attack all of us. You may not personally know any trans people, and you may even be uncomfortable with the idea ... but letting this attack go forward will eventually hurt you and the things you love, too." /1

NOAA is reportedly on the DOGE chopping block. The National Weather Service, which is part of NOAA, provides life saving weather forecasting in the US. A study found that for every $1 invested in NWS, it produces $73 in value to Americans. Again, this isn't about efficiency.

New preprint with @winterstat.bsky.social and Ellen Fitzsimmons on ordinal factor analysis, where the latent variables are scaled so that they generally take values from 1 to # of ordered categories. The scaling is intuitive because it is what you use when you treat ordinal variables as continuous.

Identification and Scaling of Latent Variables in Ordinal Factor Analysis

Social science researchers are generally accustomed to treating ordinal variables as though they are continuous. In this paper, we consider how identification constraints in ordinal factor analysis ca...
