Naast didactische bedenkingen, is mijn grootste probleem met de huidige lichting aan invulboeken dat de aan te brengen inhoud te vaak slordig, onvolledig tot fout beschreven staat. Zonder zorgvuldigheid in leermateriaal, kan je geen zorgvuldigheid aanleren.

I'm grateful for receiving the Ulrich L Rohde Award for my work in Maia SDR, and happy for having met many friends and made new ones at Friedrichshafen. Since there was interest in the paper I submitted to the SDRA proceedings, I have uploaded a preprint: https://t.co/f4R9vEbyWm

Zal Colruyt ook de honderden miljoenen euro's aan subsidies terugbetalen die ze van de belastingbetaler kreeg om haar windmolenparken op te richten en uit te baten, nu ze deze doorverkoopt voor 1,55 miljard euro aan het Japanse JERA Green?
