Lifelines of young people with a history in residential care: A qualitative investigation from a complex systems perspective Care for youngsters in residential settings is often disorder focused rather than based on a holistic understanding of their unique developmental hist…

What would a qualitative methodology for complex systems research into psychopathology look like?

Maybe this could be an option... Very fond of the innovative and creative work done by first author Rineke Bossenbroek.

Vakbonden: 9 december demonstratie tegen ‘sloop’ hoger onderwijs Er komt opnieuw een actie tegen de bezuinigingen op het hoger onderwijs op 9 december.

Terwijl het deze campagne nauwelijks gaat over onderwijs, stemde vandaag een rechtse meerderheid in de Eerste Kamer in met nieuwe bezuinigingen.

Weer met hulp van het CDA.

Hopelijk neemt iedereen met hart voor onderwijs of opgroeiende kinderen, dit mee in het stemhokje.

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.

Beste bestuurders,hoogleraren & hoofddocenten, teken deze petitie: lnkd.in/eRFpyiHw tégen procentuele inflatiecorrecties die loonverschillen almaar vergroten.

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 ...

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'!

Thanks to @cuijingmeng.bsky.social for helping with uploading

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 have a Dutch word in mind, I hope this is a sensible translation)

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.

Super happy and excited to share that our manuscript (with Fred Hasselman, @molthof.bsky.social , and Anna Lichtwarck Aschoff) has been accepted by the Journal of Psychopathology and Clinical Science! 🥳

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."

... 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.

We combined affect dynamics with contextual data and qualitative information from data viewing sessions with participants in order to study whether non-stationarity may signal transitions...
