How can I improve my chances of receiving PhD funding (UK, Anthropology)? I have been accepted to UCL and Oxford for a PhD in anthropology, however I have not been offered funding for either position. I am considering reapplying next year and I would like to know how I can improve my chances of securing funding. I already have experience as a research assistant for my MSc supervisor, and she has acknowledged me in a recent paper. I have also presented at a conference, though I have not published the paper. Would publications improve my chances, even if not in top tier journals? What other things could I do to make my application stand out to funding committees?

I should add that this is my second attempt - I was in the same situation last year when I applied only to Oxford for a PhD, gaining acceptance without funding. I received my MSc from Oxford, with an overall grade of 67 and a distinction in my thesis.
Funding is extremely scarce, especially in Britain. Since you have been accepted, I would write to the person who you suspect would be your adviser if you matriculated and ask them for advice. The program clearly has an interest in bringing you in. They may be able to find fellowships or paying jobs within the university that can help you financially.
