Well, right now it's more or less just looking at the population afterwards and watching their individual transformation.
If we have one great need, it's to have a more studied analysis of outcomes. We are now talking to a Yale campus in Singapore about having them follow our program and track the outcomes of the students on a more comprehensive basis and more scientifically.
The feedback we get specifically from our NGO partners is that the students have all been profoundly changed. In many cases we see that those who would not have graduated from high school do; those who would not have gone on to college do; many of them have gone on to careers unrelated to photography, to medical school, as an example.
It's not exactly scientific at the moment, but we are hoping to solve that problem.
