The model starts in 1900. In the year 2000 you get the chance to set a new emission target and nominal time to reach it. Your aim is to have atmospheric CO2 stabilise at about 400 ppmv in 2100. From Sterman, John D. (2008) Risk Communication on Climate: Mental Models and Mass Balance. Science 322 (24 October): 532-533. Older version of IM-9283.
Climate Stabilization Task - Older
This model shows the Pharmaceutical New Drug Pipeline based on drug release, approval and patent expiry. This pipeline is then linked to patients switching from older drugs to newer drugs based on proven indications and marketing (indication creep). Based on work by Mark Heffernan on the Australian Pharmaceutical Benefits Scheme for drug subsidy.Conference paper and Larger ithink model
Pharmaceutical Pipeline and Medicines Use
From fighting lions (fight or flight) to fighting feedbacks in complex systems. A single person cutting the Gordian knot to the dynamic complexity of rubik's cube. Think of multiple players with multiple misperceptions of the faces on the cube and conflicting goals about what the desired solution is. Worse still, without an accepted framework we dont even know if it's a cube or another structure. See also policy resistance IM-697
