Complexity Science: A Case Study

Underwriting Cycles[1]

In this case study for Complexity Science, we aim to show its value addition through agent based modeling of an important insurance problem, i. e, underwriting cycle.

Sweet and Short Introduction to Complexity Science

End-of-Life Narrative

Canada will soon be passing legislation to allow for physician-assisted suicide.  Sometime over the course of debate between our Parliament and Senate, I found what at the time seemed like a peculiar pattern of woodchips in the back of my pick-up.  It was such an interesting image, I thought I would share it here.  On closer inspection, I discovered that in fact I was looking at hundreds of tiny flower shafts and seeds.…
