Juuust checking... nope, still Monday. #MondayMotivation
A young Great Spotted Woodpecker with a red crown peeks cautiously out from a hole in a tree, only part of its head and eye visible. Its expression looks wary and slightly resigned, as if checking on something it already knows it won’t like.

Despite the extreme heat today, I went to @w-u-r.bsky.social to celebrate 60 years of Marketing and Consumer Behavior research, followed by the impressive inaugural lecture of Prof. Dr. Ilona de Hooge. Definitely worth the trip!

I highly recommend this very clear, helpful and practical paper on statistical inference with marginaleffects package. I added it to my lab’s “required reading” list.

Last day of #EMAC2026 done. Two solid sessions, a walk down from campus into Bath, and later a proper city walk through the downtown area, Herschel museum, logged a geocache along the way (nice multi!). And a great party to round it off. Good edition!! Heading home tomorrow.

Starting Day 3 at #EMAC2026 with a panel discussion on open science practices in our field with @anamartinovici.bsky.social and others (not on Bluesky 🙂).
Five panel members and a moderator in front of a large projector screen.

Tuesday, I joined about 7,500 colleagues in Amsterdam to strike and protest against the budget cuts in higher education. With a new coalition taking shape, it’s worrying how little attention education gets. Cutting education budgets is so short-sighted! #WOinActie

An pile of books is unfortunately less impressive than a tractor. All the more reason to go all together to The Hague on Monday.
