A new study confirms what I’ve known for years: ambivalent ties (relationships w/ intermittent stress + support) may accelerate aging *more* than purely negative ones. Half-and-half ties (like with dysfunctional family) can be the most damaging. Very validating! pubmed.ncbi.nlm.nih.gov/40475146/

Excited to share my paper published in ASR on unemployment and suicide!! Using big administrative data on suicide, we show that unemployed people are more likely to die by suicide, but their suicide risk is lower when and where more people are unemployed. journals.sagepub.com/doi/10.1177/...

All she did was write an op-ed. That's it. One of my past mentees is a current international student at Tufts. This is absolutely terrifying.
Video of the international student at Tufts being arrested by "federal authorities" in Massachusetts has been released and it's terrifying.

They're not even uniformed officers. Just secret police thugs in hoodies and masks.

Shame. This is happening across essential institutions: media, Congress, law firms, & now universities. Instead of standing up to illegal authoritarian power grabs, they capitulate, hoping the threat will pass. It won’t. And as the rule of law & the constitutional order die, so does our democracy.
"A Columbia senior administrator said the school considered legal options ...but ... the ... government has so many available levers to claw back money, it would be a difficult fight. Additionally the school believed there was considerable overlap between needed campus changes and Trump’s demands."
This is a shameful moment in the history of the American university.

A US-born citizen was walking near Chicago in January. ICE snatched him off the street, handcuffed him, threw into a van. His wallet, which contained his ID, was confiscated. He was detained for 10 hours before being released without a record of what occurred.
