The City of Ottawa posted the raw speed data from before and after Doug Ford banned speed cameras and the effect is so obvious it's not even necessary put a line marking when that happened. This chart shows the percentage of drivers going 15km/h or more over the posted limit.

Chapter 5: @martinarvidsson.bsky.social, Hedström, Jarvis & @marckeuschnigg.bsky.social on the intersection of Analytical Sociology and Computational Social Science. Computational tools are most powerful when used to identify and test mechanisms, not just describe or predict aggregate patterns.

In Chapter 4, Ralph Schroeder of @oii.ox.ac.uk argues that CSS needs a stronger theory, not just better data. He proposes an AI-driven model of media agenda-setting that links media visibility, public attention, and political change. A big step toward cumulative media theory.

The choice is impeachment and removal or calamity for the United States. I don't see how anybody watching Trump's speech in Davos can draw any other conclusion. He's a senile madman.

This paper shows welfare programs alleviating health shock can reduce crime. It makes case poverty scholars have long made about the negative costs of poverty to society. The societal costs of crime need to be factored into benefit-cost analyses of poverty reduction programs.

New paper out with @kchihaya.bsky.social and @eduardotapia.bsky.social. We show how a tendency to move near kin can preserve patterns of segregation, using a combination of discrete choice models and micro-simulations applied to the case of immigrants and their descendants living in Stockholm.

“Kin Propinquity, Residential Mobility & Segregation”: @benjarvis.bsky.social, @kchihaya.bsky.social & @eduardotapia.bsky.social examine ancestry & segregation; they find ancestry sorting effects are 3X greater than kin propinquity effects. @iasliu.bsky.social read.dukeupress.edu/demography/a...

it is *critically* important now for Dems to create a climate in which there is a threat of punishment once power is switched. The more we can create a threatening shadow of the future, the greater the probability of preventing harm in the present

New article w/ @jenjirayahirun.bsky.social: Exogamous 2nd gen immigrants in Sweden live further from parents than do endogamous immigrants, but closer than natives. But in terms of residential choices, exogamous immigrants are least likely to move near parents.

The Swedish Foundation for Strategic Research has a call for grant proposals for US-based researchers with Swedish citizenship or a degree from Sweden who want to move to a Swedish university. SEK 15 million over 5 years. Aimed at science and tech, so maybe a CSS researcher?

Amazing. Right out in the open: "universities are free to do research as long as they're sympathetic to the administration." I want to personally play this clip in the face of every fucking clown who spent the last several years pretending that the left is the "real" threat to free speech.

Linda McMahon: "Universities should continue to be able to do research as long as they're abiding by the laws and in sync, I think, with the administration and what the administration is trying to accomplish."

👇🎯 Been saying this for years. But it's actually worse than this. They think we are less worthy of actual citizenship & openly suggest that our votes shouldn't count, & they pay absolutely no consequences for this in the National Conversation™️: bsky.app/profile/mcop...

Conservatives kvetch all the time about how liberals hold rural areas in distain but no one in this country hates anyone more than Republicans hate cities.

It's been a couple wks since the various reports of Trump's incursions at the LoC. In that time, I've been backing up the OCR text of Chronicling America, just in case I documented my process on my blog. Just sharing in case others want/need to back up Chron Am for their own peace of mind

Some sad confirmation from @bcgl.bsky.social while I was at UW last week—the National Digital Newspaper Program—which builds Chronicling America—has been shut down Historical newspapers are probably the archival material most used by the general public—for genealogy, local history—it’s such a loss

A major escalation of the ongoing weaponization of the federal government against institutions that are deemed insufficiently obedient. This isn't about Harvard, specifically: This is an authoritarian regime weaponizing the state to force civil society institutions into submission.

I’m old enough to remember the IRS “scandal” from the Obama administration that the GOP fed to a thirsty media, parlaying it into reams of tedious coverage and hackneyed “news analysis”. Every accusation is a confession for these malign mungers.

I.R.S. Is Said to Be Considering Whether to Revoke Harvard’s Tax-Exempt Status

The move would be a major escalation of the Trump administration’s attempts to choke off federal money and support for the leading research university.

There are serious concerns about the data validity of the income measurement of the EU-SILC in Hungary after 2017. The numbers reek of manipulation to make the Orban government appear better at fighting poverty than it actually is. This is serious, as it undermines trust in the whole data set.

Lili Vargha@lilivargha.bsky.social · last yr.

Anomalies & data problems are found in the Hungarian EU SILC income data from around year 2017. It is very likely that the data was manipulated to decrease the poverty rate. Annamaria Tatrai and Andras Gabos conducted a very thorough investigation of the issue: www.valaszonline.hu/2025/04/01/e...

I've already had two federal grants terminated and face a 33% pay cut due to future terminations. It's painful, but not as painful as the conversations I'm having every day with brilliant trainees in graduate school and postdoctoral positions who see little future for themselves in US science.

www.nytimes.com/2025/04/03/o... Really important piece to share widely. Too many Americans don’t know how severe a threat this Administration poses to our scientific infrastructure, global leadership, and health security
