Christopher Keane developed this model of perceived need, self-efficacy, behavior and imitation, joining this to a sandpile model. See chapter 5 of his book for details (2013). The sandpile model itself is known as the Bak–Tang–Wiesenfeld sandpile model.

If you mention this model in a publication, we ask that you include these citations for the model itself and for the NetLogo software:

As usual, much was borrowed from the basic NetLogo program developed by Wilensky.
