Thank you. unfortunately, it seems like RG filtered the links. Can you past them without the dots so that they don't seem like a web address and they're not filtered, please?

I would look at Maylei Blackwell's chapter in Dissident Women, (edsLynn Stephen, Shannon Speed and Rosa Aida Hernandez Castillo). She talks about multi-scalar strategies of social movements in Chiapas-- local and national. You might also look in the geography literature. Blackwell uses the following article: 

Staeheli, Lynn 1994  Empowering political struggle: spaces and scales of resistance. Political Geography 13:387-91.

The place to start is with Mark Granovetter's (1973) The Strength of Weak Ties. Granovetter has given us a way to adequately theorize the whole idea of 'tipping points". What normally happens in the growth of social movements is that, as grievances accumulate, people become more and more willing to see themselves as part of an aggrieved whole. This is usually the result of the further activation of the weak ties between strong social networks, a phenomena often linked with precipitating  events. The best recent research on this was done during the Arab Spring by analyzing the way social media networks were used to by pass official information nets and attempts to restrict data flows among the protesters. It is no wonder that this often surprises the authorities; much of what we do with each other is both below their event horizon and impervious to their attempts at control.

Thank you very much, I had missed these responses.
