I suspect within the living community in question. The scientific model of being an outside observer falls flat in a complex environment, as any self-styled observer is part of it, and can only succeed by realising that. Brings me to action research too. If they're hard to find from outside such a living community that's probably because they don't partake in the academic status games that run separate from those living communities. How would you recognise one if you aren't at least yourself a boundary spanner to the living community they are part of?
