Method: extinction of social groups (such as agricultural OR)

Interesting article on social group dynamics using a non-linear dynamics model. The interesting thing is can the para,meters be managed to prevent small groups fading away.  Is there a critical mass?

Nonlinear dynamics is invoked to explain a wide range of physical phenomena in which a number of factors play a part.

One of the team, Daniel Abrams of Northwestern University, put forth a similar model in 2003 to put a numerical basis behind the decline of lesser-spoken world languages.

At its heart is the competition between speakers of different languages, and the “utility” of speaking one instead of another.

“The idea is pretty simple,” said Richard Wiener of the Research Corporation for Science Advancement.

“It posits that social groups that have more members are going to be more attractive to join, and it posits that social groups have a social status or utility,” he told BBC News.
