'Dependency' or disabilty?

The attached article appeared in the Winter 2011 issue of the journal Soundings http://www.lwbooks.co.uk/journals/soundings/current.html It develops some of the material from the Compass conference presentation on this site http://lartsocial.org/node/2#overlay-context=node/2 in more detail. Thanks to Jonathan Rutherford for commissioning it, and to Sue Marsh and Kaliya Franklin for assuring me there was an audience for it.
