The aggressive immigration raids we now see across the nation began 10 months ago in California's Central Valley. Their impact on children, families, and communities is an important & active area of research I'm pleased my study of the initial raid's early impact on students is now out in @pnas.org

Hmm, I also don't know what it means, but I know how to make your kids stop using it at home, fellow parents. Adopt it and let it slip casually into conversations with your kids.😉 www.theguardian.com/education/20...

It might be hard to convey to people outside economics just how seismic this is. The Trump effect has most certainly arrived to US academia.

Real change in public expenditures on higher education, 2008 to 2023, selected countries that actually publish the damn data. UK is worst here, but note this does not include RAB (projected future loan forgiveness, basically). If RAB is included...UK would still be last.

Trump does shit every day that should get him impeached. But illegally punishing an entire country — and any Americans who use products or do businesses with anyone in Brazil — because it’s prosecuting its former president for attempting a violent coup is among the worst things he has done.

I left Ireland and moved to New York in 1997. Decades on, what the US has become has broken my immigrant heart. It also baffled me, until I began to piece together Gen X memories of apartheid South Africa.

I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior. (There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)

After extensively studying the strategies implemented by Bolsonaro's government to undermine public administration, I can confidently assert that these tactics follow a tested playbook. This approach has been employed by various governments globally and is now being adopted by the Trump admin. +
