This is latest blog post on the upgrade or transfer process for doctoral candidates:
"The document submitted as part of an upgrade or transfer process in a doctorate is a particular genre of writing that is sometimes underplayed by doctoral students. As a genre, it represents, among other things, a cogent proposal of your doctorate, its potential implications, and the context of your study. When done effectively, it’s a great way to conceptualise your study: the what, why, how, and so what of it. It addresses why your project is a worthwhile doctoral study, and why YOU are the one who should carry it out."
