We were just notified that our contract to UCSD and Scripps Research to support wastewater surveillance in San Diego (searchcovid.info) was terminated immediately for the same reasons 👇. That means no more genomic wastewater surveillance, and our proposed extensions to measles, Hep A, others, gone.

Als jij hoogleraar of uhd bent, dan is jouw salaris er in de afgelopen jaren honderden euro’s meer per maand op vooruit gegaan dan dat van veel van je collega's. De boodschappen zijn echter voor iedereen evenveel duurder geworden. Teken daarom deze petitie voor 'centen in plaats van procenten'!

Om de eigen kleine belangen weer relevant te maken in de huidige geopolitieke onrust, claimt BBB dat krimp vd veestapel de (internationale) voedselzekerheid bedreigt. Maar het tegendeel is waar: onze vee-industrie draagt bij aan voedselschaarste. Dieren eten meer calorieën dan ze leveren.

Bij sociale huur denken we aan subsidie. Bij villa's denken we aan 'hard werken'. Jaarlijks subsidieert de overheid eigenwoningbezit met €14 miljard. Ruim twee keer meer dan de €6 miljard huurtoeslag. Dat is een herverdeling van arm naar rijk. Nederland kent hierdoor een netto subsidie op vermogen.🧵

"It does not make sense to think of our judgements as being estimates of ‘true’ probabilities." David Spiegelhalter's excellent introduction to the nuances and intricacies of probability. doi.org/10.1038/d415... #Methodology #Statistics #Probability 🧪
There is a limited range of well-controlled, repeatable situations of such immense complexity that, even if they are essentially deterministic, fit the frequentist paradigm by having a probability distribution with predictable properties in the long run. These include standard randomizing devices, such as roulette wheels, shuffled cards, spun coins, thrown dice and lottery balls, as well as pseudo-random number generators, which rely on non-linear, chaotic algorithms to give numbers that pass tests of randomness. In the natural world, we can throw in the workings of large collections of gas molecules which, even if following Newtonian physics, obey the laws of statistical mechanics; and genetics, in which the huge complexity of chromosomal selection and recombination gives rise to stable rates of inheritance. It might be reasonable in these limited circumstances to assume a pseudo-objective probability — ‘the’ probability, rather than ‘a’ (subjective) probability. In every other situation in which probabilities are used, however — from broad swathes of science to sports, economics, weather, climate, risk analysis, catastrophe models and so on — it does not make sense to think of our judgements as being estimates of ‘true’ probabilities. These are just situations in which we can attempt to express our personal or collective uncertainty in terms of probabilities, on the basis of our knowledge and judgement.

Didier Raoult now published a 'preprint' claiming I am 'close' to Gates Foundation - citing a France Soir article as the reference. He also suggests that my poor facial recognition skills are linked to autism, with 'serious psychosocial consequences'. What a sad man. hal.science/hal-04795904/
Highlighted text from the article:

"This platform has been widely used by Elisabeth Bik, a biologist with a scientific background who has a self-proclaimed "fraud hunter" whose funding for this activity is totally obscure and is close to the Bill and Melinda Gates Foundation (9). She recently confessed in an interview (10) , she was a victim of face blindness also call prosopagnosia, a condition link to autism in 36% of cases (11) and which may have serious psychosocial consequences. She said his brain has the uncanny ability to spot retouched or doctored images in a fraction of a second. She explains that his neurons, by a strange mechanism, launch themselves in search of repetitive patterns, replicated angles, points or similar lines scattered throughout the pages. She manages to spot copy-paste even when an academic has taken care to flip the original image or edit it in Photoshop (10). "Before, I thought everyone was like me...". “I only recently realized that I had some kind of special ability. ». This donation will push her to flush out scientific fraud using the PubPeer platform."
