The rise of resistance against climate policies by Kai Neumann

Whether it is Germany's "Heizungsgesetz" or the European Union's "Renaturation Law" there is a certain pattern how resistance evolves. Recently I was on workation sailing the Baltic Sea observing lots of signs of movements against the implementation of protected natural habitats in the Baltic Sea. The fishing 'industry', the tourism, and the water sports enthusiasts all seem united in their protest against the protection of the Baltic Sea. Fact is, that the Baltic Sea is in an extremely poor condition ca...

Cheap meat trap by Kai Neumann

they want it because others want it ... so others just need to stop wanting it (whether we refer to developed countries or wealthy opinion leaders). btw: the inspiration to this model came from the club party of our sailing club where we get a huge buffet with all sorts of meat and fish and only minor vegetarian alternatives (not as a main dish). Asking the organizers the reaction was, that even the wealthy people of the club expect to eat tasty meat for as little money as possible and that they wouldn't...

Matching data example - calibrating a model by Kai Neumann

While listening to a presentation on the ISDC2023 where they showed a sophisticated way of calibrating parameters of a model to real data I decided to offer a simple solution using the iMODELER's iM-Optimizer. The idea is to minimize the deviation of the model results from the real data using a range() for all variable parameters. Simple as that though of course it also has some limitations.

Wind industry's growth and over-investment archetype by Kai Neumann

just a small model to understand why the stocks from wind energy providers are loosing value ... despite the increase in installations. Peter Senge described the "Growth and underinvestment" archetype - this model rather features the "Growth and over-investment" archetype.

Migration debate in Germany ... and elsewhere by Kai Neumann

Migration has just started and it will become much worse. It is a symptom, a consequence of our exploitation of the world - which sounds idealistic but actually it is a fact that most economists easily agree to. We definitely can't take them all and the better they are are integrated the more will come. There is no silver-bullet to it but some measures (green factors) that we probably have to take all. What is interesting (see the Menu .... Presenter) is that long-term the help for migrants abroad has al...

Die Geschichte wird urteilen - so es eine Zukunft gibt by Kai Neumann

Wir müssen uns gegen den Vorwurf der Ideologie wehren - es ist ein äußerst effektives Meme. Die, die es für die Wahrung von Partikularinteressen streuen, könnten wir "Ego-Trolle" wider dem Gemeinwohl nennen, und die, die es unbewusst aus Schutz vor Veränderungen weitertragen, "Troll-Lemminge". Aber vielleicht gibt es ja noch bessere Bezeichnungen. Transformation an sich braucht dann noch mehr: https://www.know-why.net/model/CuHDpfvLxDg3dHwb5O6XR8Q https://www.know-why.net/model/BBR98dvgyVVsUZHIjIRV7Gg bz...
