Reflexion on thorium reactors by Kai Neumann

this is just a first scetch of a cause and effect model ... if you look at the matrix of the factor thorium reactor you will recognize that this model is dominated by balancing feedback loops (...) you may contact me (kai@ilsa.de) to get a copy of the model or even to collaboratively model it with me and others in any way: many insights and happy modeling Kai

Solution: A healthy environment on earth by Kai Neumann

A model exploring the challenge of less pollution This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the measures for a healthier environment using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. I...

Solution: Where do our vegetables come from by Kai Neumann

A model explaining the basic loops of agriculture This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the sustainability of farming using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. When we cont...

Winning the Fairphone: a collaborative model on the development of house (real estate) prices by Kai Neumann

This is a collaborative qualitative model on the development of prices for real estate (houses, apartments etc.). While there is already a collaborative model on the development of stock markets (https://www.know-why.net/collab?id=CzSkr0IaGNcHWA9aGfE0Y-A) I would like to gain more insights on house prices as well. Background: while the population is shrinking we still see a boom in the construction of new houses. I thought that this was only because of low interests but experts told me a couple of demogr...

Joint Report - case study 1: Impact of GMT on resource scarcity by Ulli Lorenz

“Possible impacts of global megatrends on resources scarcity (general concept from the perspective of northern Europe)”This model is the basis for the case study 1 of the report: "Impact assessment of global megatrends - Two case studies connecting global megatrends to regional topics" by UllrIch Lorenz and Hördr V. Haraldsson The case study 1 examines the general mechanism of resource scarcity. The global megatrends – as described in the State of environment report 2010 – are included in the model as we...

The price of sustainability by Kai Neumann

Being tired of the complaints that renewable energy is expensive, that we cannot afford the conservation of natural habitats, that not all people can purchase organic products, that our industry looses jobs, our citizens cannot bear the burden of the costs of sustainable solutions, and so forth I started this model. As it turned out it is not as easy as I thought. My original assumption was that any additional expenses should - with a high domestic value creation compared to the import of fossil fuels - ...

Systemic view on terror threats after Paris by Kai Neumann

Just the start of a small model on the basic interconnections behind the growing threat of terror. You may use the collaborative link to edit the model or provide a complete new model.

General model on transition, tipping points and crossing the chasm by Kai Neumann

Just a small general model on tipping points (using the Bass function that can be found e.g. in Sterman's 'Business Dynamics'). The model distinguishes between first movers, early adopters and the tipping point (Malcolm Gladwell) of an adaption by the majority of potential adopters. Getting from early adopters to the majority can be named 'crossing the chasm' (by G.A. Moore). The model can be used for both, explorative qualitative modeling of factors the hinder and foster the tipping point, or a continua...
