Mine was too but I read slow…not a great trait in grad school lmao

Yeah, not with the weird moralizing about games. I’m stunned you finished twice in 38 hours though, my first play through was 70-something

PhD students working on topics related to crime & the criminal justice system in the US:

Join us for a research workshop this October! We're bringing y'all together so that you can meet each other, and (selfishly) so the Arnold Ventures CJ team can meet you.

Sign up by August 11! bit.ly/3GUT0De

There's a large group of (mostly online) people who value moral purity over putting in the work to make change. Skeptical of anyone who thinks the answer to society's ills is to withdraw from it completely

Happy to share new paper on "State Actors as Hard-to-Reach Populations"

The secret to Baltimore's extraordinary year This April, Baltimore saw five homicides.

1. We interrupt this programming for some LEGITIMATELY GOOD NEWS

Violent crime in Baltimore has PLUMMETED to historic lows

How did the city do it?

Baltimore adopted a comprehensive set of "woke" policies, treating violence as a public health issue

A huge congratulations to the newly-minted DOCTOR @alyssa-laberge.bsky.social!

Alyssa has worked with me for 7 years, first as a master’s student and then as a PhD student. Her growth as a scholar, teacher, and person has been such a joy to witness.

She’s on to a TT position at UW LaCrosse!

Greatest book on research design for making causal inference in the game. Don’t think there’s a better example of breaking down a bunch of complicated concepts and giving you the tools to apply them (though there are a bunch of other good ones). Check it out if you haven’t yet!

Traffic calming and diversion work well, study after study finds. And not only they reduce traffic deaths and injuries, but they also have no impact on nearby streets because car traffic overall goes down (ie “traffic evaporation”).

Y’all they finally noticed how good I am at the library.

Excellent read. Claims to unbiased, objective, and apolitical research read more as a sterilization aimed at shrugging off criticism than anything good-faith. If open science advocates are serious about trust in science, not just faith in science, this is foundational.

Ineffective reforms are frustrating for both communities and police agencies. It's important to assess the pervasiveness of problems to understand what effective solutions might (or might not) look like. Open access!

Recently published in Journal of Quantitative Criminology with my co-authors Travis Carter and Scott Wolfe: we develop a framework for diagnosing disparities in policing outcomes, including whether they are concentrated or diffuse across groupings (e.g., "bad apples," types of stops, neighborhoods).

Whooooo congrats!

Pictures of pink Cosmic Cherry Petunias

Gorgeous! Petunias are one of my favorites to grow, definitely adding these to the list. We grew Cosmic Cherry Petunias last year and dried the blooms for tea - so gorgeous and bloomed through September, even in Zone 5.

I was in Trio in undergrad. Specifically, Student Support Services. Mr. Winston played a huge role in getting me through undergrad. These programs are small but really matter.

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics. We had 146 teams perform the same research three times, each time with less freedom. What source of freedom leads to different choices and results? papers.ssrn.com/sol3/papers....

Say you’ve got very good causal IDENTIFICATION. Can you say you have causality, can make a causal general claim, and can say what “THE causal effect” is?

NO

We explain why in new article at Journal of Causal Inference.

Michigan’s Great Start Readiness Program yields positive economic return

My new report, on shorter-run economic benefits of Michigan's state pre-K program, was released today by @upjohninstitute.bsky.social . This links to the Research Highlights page, from which you can access the full report: www.upjohn.org/research-hig...

I really liked this idea of using a histogram as a legend in a choropleth map (since land isn't unemployed; people are), so I made a little guide to doing it with #rstats, {ggplot2}, and {patchwork}

My recent paper update got a fair amount of attention on here and so I decided to make a thread!

The paper studies recruitment at major US and European multinationals to quantify the salience of hiring discrimination in access to top jobs and identify its source…🧵

Embracing the process is the absolute antithesis of AI, which puts results above all and constantly forgets to include all the fingers. Because if we don’t love the process, what is even the point of anything?

Heard from two different people today about their NIJ-funded projects that are held up because they have to change survey questions (and go through approval again) to remove refs to gender and ask about bio sex only, two answer options. The studies themselves are not on 'DEI' topics.

Cities speak different dialects but share the same grammar of exclusion. My latest piece explores how everyday warnings—'don't go there,' 'stay away from that neighborhood'—transform segregation from policy into practice, and what we can do about it.

Yeah. Highly recommend you look into NHGIS in the meantime. Inconvenient since you have the code using tigris written but you can get all the same stuff at least. Hopefully someone smarter than me makes a library utilizing NHGIS since *knockonwood* IPUMS is committed to maintaining these records.

NHGIS is my kid, because IPUMS is clearly the GOAT
