"Holding my dad’s hand: a photographic essay" https://observer.co.uk/culture/photography/article/holding-my-dads-hand-a-photographic-essay "Cultural taboos about men holding hands mean fathers and sons rarely do so as adults. But when Valery Poshtarov set out to take portraits of this connection the results were both touching and telling"

"Les résultats confirment qu’à niveau de diplôme, âge, secteur d’activité, profession et autres caractéristiques observables données, l’absence d’autonomie au travail renforce nettement l’abstention aux élections. Pour les salarié.es qui votent, la possibilité de s’exprimer sur leur travail dans le cadre de réunions formelles contribue à orienter leur vote vers les candidats du centre (macroniste) ou de gauche, et les éloigne du vote RN" https://ires.fr/wp-content/uploads/2024/02/DdT_T_Coutrot_2024_2.pdf
"Une hypothèse un peu malveillante serait d’y voir une sorte de racisme refusant aux Chinois la capacité d’égaler les Européens ou les Américains dans l’activité scientifique.

"Japan is often seen as one of the safest countries in the world, but that same strict order comes with laws that can catch people off guard. Something as small as getting into a heated argument in public, accidentally taking an item you didn’t pay for, overstaying a visa, or even grabbing someone else’s umbrella or bike thinking it was yours can escalate further than you could imagine" https://sundaicity.com/blogs/getting-arrested-in-japan
"For the first time in my life, I genuinely do not know what academia will look like in five years. Even if progress stalls completely and we are stuck with the current models forever, the changes already in motion will transform my field of academic research and publishing beyond recognition. The status quo is unsustainable. It may take time, because academia is the most dispositionally conservative institution on the planet. But it will change" https://www.popularbydesign.org/p/academics-need-to-wake-up-on-ai?triedRedirect=true

"More than a century before Japanese whisky became one of the most coveted spirits in the world, a young merchant in Osaka had a simple observation: the wines and liquors being imported from Europe didn’t suit Japanese tastes.

"Even recruiters will admit it’s fair to wonder. The CEO of a hiring platform said last fall that his industry is in “an AI doom loop”: HR departments complain of a wave of AI-generated job applications, prompting the need for more AI filters.
