I don't agree with some things in this (very sharp) blog post, but it certainly offers a new angle on "AI and academia". Papers will become less valuable, prestigious institutions - more. But also (and here is me thinking) - direct communication unmediated by text. giorgio.gilest.ro/the-weimar-o...

Researchers investigated language change by studying Slovotvir, a Ukrainian website where users propose and rank alternatives for foreign-origin words. The site shows that people prefer shorter words, but not necessarily more common words. In PNAS Nexus: ow.ly/KWGE50ZNzaj
The study used an agent-based model. Diagram of a two-step agent action model. Ukrainian alternatives for the word дедлайн (deadline, a borrowing from English, possibly through Russian) are given as an illustration. In step A, an agent chooses a word based on the number of likes received by that word’s most-liked translation. In step B, after choosing a word, the agent chooses which translation to like based on each translation’s length and number of likes.

a new paper forthcoming in Social Forces! focusing on the killing of George Floyd & the BLM, I study the formation of generations, proposing that formative events can create within-cohort differentiation as much as between-cohort differentiation. read here: tkeskinturk.github.io/imprinting.pdf
Generational Imprinting: How Political Events Shape Cohorts
Contemporary narratives of generational politics propose that formative experiences produce shared political opinions across an age cohort. In this article, I advance a theory of cohortization to challenge that view, arguing that large-scale political events produce differentiation within cohorts as much as differentiation between them. I investigate the implications of this framework through the killing of George Floyd and the subsequent Black Lives Matter protests in 2020, analyzing attitudes toward law enforcement among non-Hispanic White Americans from 2016 to 2024. Using survey data from Cooperative Congressional Election Study, American National Election Study, and the Nationscape, I show that younger and older cohorts diverged after the event, but this differentiation was driven exclusively by young Democrats and Independents. The end result was not a unified generation, but one internally divided along party lines. This finding qualifies theories of generational politics, emphasizing that formative experiences may intensify existing political divisions within cohorts.

"AI" is everywhere nowadays, but 30 years ago similar hype was about everything "computer". I stumbled at this Italian dictionary from 1986 proudly stating on its cover that words in it were sorted by a computer 😁
For the first time, 20,000 Italian words computer-organized into semantic groups and fields of reference.

🎉 New paper (and data) on editorial & peer review at Science and Science Advances, two elite general science journals. With a wonderful team! @samzhang.bsky.social, @nicklaberge.bsky.social, Quinten and @aaronclauset.bsky.social. 1/ www.science.org/doi/full/10....
Screenshot of the title page: 

Elite general science journals shape scientific discourse, public policy, and scientific careers. However, expectations of confidentiality in most editorial proceedings has limited efforts to understand and improve the review process. Here, we describe and release deidentified data on 110,303 manuscript submissions over 5 years at Science and Science Advances, two elite general science journals. Analyzing evaluation dynamics across the initial editorial review and subsequent peer review stages, we find strong selective effects associated with higher institutional prestige, larger team size, and certain topics and countries. Corresponding authors who are men exhibit a small but significant advantage at Science, while authors based in China have a significant disadvantage. These associations are generally stronger in editorial review than in peer review, even as final editorial decisions correlate strongly with reviewer advice. These patterns highlight the complexity of multistage evaluations at elite journals and the importance of open data to better understand them.

This pattern often noticed for cars seems to hold also for furniture... from: europeancorrespondent.com/en/r/how-col...
Bar chart titled 'Furniture lost its colour: Recently purchased IKEA sofas are more likely to be grey than older ones.' It shows the most common sofa colours per year in IKEA catalogues from 1960 to 2021 as a sequence of coloured vertical stripes. Three callouts highlight the trend: green and blue dominate the 1960s; patterned sofas (stripes, dots, checks) take over in the 1990s, shown as dense black-and-tan patterned bars; and 2011 has the most neutral colours ever. Moving left to right, the bars shift from saturated greens, blues and reds in the 1960s-80s, through heavily patterned dark tones in the 1990s, to blacks and whites in the early 2000s, ending in solid grey and taupe shades through the 2010s to 2021.

Very excited to share this preprint from me, @emmatempleton.bsky.social, @lindseytepfer.bsky.social & @thaliawheatley.bsky.social! "Friends and strangers engage in distinct regimes of body motion synchrony during conversation" osf.io/preprints/ps...
 Forms of body motion synchrony. A) Motion quantity synchrony – synchrony in the amount of motion (orange) people engage in over time. This form of synchrony is agnostic to the direction of this movement, may be positive or negative, occurs at varying time lags, and is not specific to matched body parts across members of the dyad. B) Pseudo-synchrony – motion quantity synchrony between people who are not actually interacting. That is, members of different conversations engaging in similar amounts of motion at similar points in the conversation relative to its initiation. And C) directional synchrony – people moving the same body parts in the same direction (or along the same axis in the opposite direction) at the same time (or at some specific time lag). Mechanisms of synchrony. A) Turn-taking, which causes increases in motion around the time of speaker role exchanges, as participants gesture to hand over or take over the floor. B) Conservation of motion in which one participant moves less when the other moves more, holding the total motion quantity relatively constant over time (note that the total amount of motion across the dyad is similar in the two panels, because one person reduces their motion to balance out the increase in the other’s motion). C) Entrainment, in which mutual following of the same conversational script leads to synchronized movement among people who are not directly interacting (i.e. pseudo-synchrony). Greeting gestures such as the handshakes depicted are one acute manifestation of this entrainment. D) Station-keeping, which maintains proxemic distance and eye level between members of the dyad. This mechanism accounts for directional synchrony, particularly between strangers who feel uncomfortable within each other’s personal space.Motion quantity synchrony among friends and strangers. A) Friends displayed significant positive synchrony in total motion quantity at short time lags (< 2.5 s) and B) this effect generalized across the majority of body part pairs (each line represents one pair). For example, one series of points might represent the synchrony between the amount of motion in one participant’s left hand and the other’s right foot. C) Strangers displayed significant positive synchrony in total motion quantity at short time lags (< 1 s) and significant negative total motion quantity synchrony at longer time lags (2.5 – 16.6 s). D) Again, this effect generalized to most body part pairs.Directional synchrony among friends and strangers. A) Among friends, we observed statistically significant directional synchrony in only two body parts (nose and eye) and only in the vertical axis. B) Among strangers, we observed statistically significant directional synchrony in a large number of body parts in the horizontal, vertical, and depth axes.
