In my utopian vision of the future, instead of offloading all the pointless, annoying work tasks (like reports that none one will read and needlessly opaque forms) to robots, we restructure work and society so that the pointless tasks don't happen at all.

You can't... repeal... a scientific finding. At that point it's just called lying about it.

β€˜I'm Not Giving ICE Another Dime’: Schiff Says Republicans Who Vote To Give ICE More Funding Will β€˜See More Americans Die’ Sen. Adam Schiff also argued the money funded to DHS has been β€œwasted hand over fist."

ICE and CBP must not receive another cent while people are being killed, beaten, and kidnapped in the streets.

Across America and the world, people are realizing it’s not possible to appease America’s dictator.

The only way to deal with him is to stand up to him β€” and the only way to stand up to him is by joining together against him.

It's time for a massive general strike across the country.

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

A reminder to the news media: β€œconflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

I don’t want to hear anything from an elected official unless it’s a plan to defund the DHS and impeach Noem, Bovino, etc. No texts. No emails. No talk about the economy. Step up or step off.

he main phone number for the U.S. Congressional Switchboard, a central point to reach Senators and Representatives, is (202) 224-3121, allowing you to connect with your elected officials to discuss issues, find their offices, or get general Capitol Hill information. You can also find direct contact information and legislative details on official sites like House.gov and Congress.gov to communicate with your specific Representative or Senator about bills and concerns

No science or nature today. ICE just murdered another person in my home state, an ICU nurse working with vets & now they're trying to frame him for the action . All because ICE is angry & afraid of the 50000 Minnesotans who marched yesterday. If you're not calling Congress you're letting them down

Tip for Californians- @padilla.senate.gov doesn’t allow VM at his DC office during non business hours (which seriously??) but you can leave a message at a local office. Neither CA Senators ever have people answering the phones in my experience at any office even during business hours.

Trump threatens to invoke Insurrection Act, send troops into Minneapolis over anti-ICE protests President Donald Trump threatened to "institute the Insurrection Act" in Minneapolis Thursday morning to quell protests in opposition to immigration enforcement.

Minnesota needs ICE to leave, not an escalation that brings additional federal troops beyond the 3,000 already here. My priority is keeping local law enforcement focused on public safety, not diverted by federal overreach. www.kare11.com/mobile/artic...

No one in America is safe from ICE. They are taking our freedoms. ICE agents who are committing crimes must be prosecuted.

ICE is shooting mothers in the face and breaking down people’s doors without warrants. I won’t support a spending bill that doesn’t rein in Trump’s masked, poorly trained ICE agents terrorizing American citizens.

Increase in productivity since 1979: 87%

Increase in hourly pay since 1979: 32%

Just so happens that ~25% of workers were unionized in 1979. Today? 10%.

As unions declined, the super-rich have taken a larger share of wealth generated by labor. We must build back union power.

Casual reminder that the myth of β€œpulling yourself up by your bootstraps” is a cruel hoax designed to convince poor people from all walks of life that the injustices they face are a result of their own actions, rather than an oppressive system rigged against them.

High-stakes exams inflate a gender gap and contribute to systematic grading errors in one introductory physics series A study in introductory physics suggests high-stakes exams are causing a gender gap, rather than measuring it.

Our new research indicates that the gender gap in intro physics is an artifact correlated with the β€œstakes” associated with physics exams and is therefore NOT due to differences in preparation or understanding. πŸ§ͺ🧡 #acadmicsky #HigherEd #EduSky #STEMed link.aps.org/doi/10.1103/...

This thread illustrates why it’s so important to think about grades and grading from the student perspective.

In this study, the retake opportunities were built into regular class time. Students who didn’t want to take advantage of the opportunity would just leave class early. Perhaps that makes a difference.

It’s potentially the same phenomenon, but- If stakes cause anxiety and anxiety causes the gender gap - which thing actually causes the gap? Instructors can control stakes- but they can’t necessarily control anxiety. Exam Stakes are a course structure causing a bias against women. We can change this.

Lowering exam stakes could cut the gender grade gap in physics, finds study – Physics World The gender gap in exam results was much larger in the high-stakes classes that did not allow retakes

We also got a nice write-up by Physics World! @physicsworld.bsky.social

These 3 independent results can all be explained by the hypothesis that exam stakes introduce a bias (measurement error) against women in intro physics, and that course structures (retake options, or lower stake assessments) can eliminate them. 🫳🎀

Finally, controlling for quiz grades (arguably the best predictor of success on a final exam) did not remove the gender gap on the final exam. Said plainly: for women and men who have the same quiz scores, women would perform lower on the final exam.
