Yeah, that one says it all. Much more TPL both inside and outside compared to the other things. We knew it all along!

they can be formalized mathematically. Otherwise, mathematical formalism may impede rather than expedite the exploration of very “real” problems”." (Von Bertalanffy, 1973, p. 420).

“Today mathematical system theory is a rapidly growing field, but it is natural that basic problems […] are approached only slowly and presumably will need novel ideas and theories. “Verbal” descriptions and models are not expendable. Problems must be intuitively “seen” and recognized before...

I didn't see the term relational psychiatry here, although many of his ideas made me think of De Haan's Enactive Psychiatry (which I would call relational). Although I often think about Enactive Psychiatry, so that may just be me.

Go to your university library, search for old books (at least 50 years ago) on your research topic, find out that, in a way, everything is in it already.
Much recommended.

Onderstaande grafiek toont dat de best betaalden op de universiteit er sinds 2002 €3000 per maand méér bij kregen dan de slechtst betaalden!
Beste bestuurders,hoogleraren & hoofddocenten, teken deze petitie: lnkd.in/eRFpyiHw tégen procentuele inflatiecorrecties die loonverschillen almaar vergroten.

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'!
Eerlijkere loonverdeling in het hoger onderwijs
Zeker nu minister Bruins van OCW de grootste bezuinigingen op het hoger onderwijs in decennia heeft aangekondigd is het essentieel dat de sector zich niet tegen elkaar uit laat spelen en solidair met ...

Wow, that's bad and crooked* of them to accuse you. They should reread your paper. Also, I find it very naive of them to think that you can just do science on nameless unspecified shared variance without making it a reality.

I couldn't follow the viewpoint when reading it - thanks for the clarification here. My 2 cents: I think reification is best understood as a sociological phenomenon: the language game around p. These authors make it a personal opinion/act - again distracting from possible consequences.

Mijn eerste bericht op dit platform: "Universiteiten hebben een voorbeeldfunctie. Met de aankomende bezuinigingen is dit hét moment om te stoppen met procentuele loonsverhogingen die inkomensverschillen vergroten en de sterkste schouders spekken."

De universiteit kan daarmee voorleven dat de sterkste schouders de zwaarste klappen moeten opvangen, schrijft Laura Batstra.

... and whether outlying values may signal recovery from perturbations. At least in these cases, they do, which means that non-stationarity and outlying values should not by default be regarded as methodological problems as they may signal meaningful and relevant phenomena worth studying.
