 We show in particular that the model can give rise to many diverse qualitative dynamics : ephemeral or limited-duration social movements-referred to as "riots"-in the tension inhibiting case, and persisting social movements-lasting upheavals-in the tension enhancing case, as well as other more complex behaviors in some mixed cases .
