They're not exactly specialist agencies but they have a great deal of experience and they have a commitment to a certain kind of research, and they have, I mean we've had our run-ins with them as it were, but they have listened, and they've supported some of our work as well , and I think that they in time will provide a kind of model as it were for a number of erm perhaps less experienced agencies throughout the world, newly set-up ones, as to how it is possible to do consistently good logical rational work in the face of the chaos that a disaster produces.
