There are several studies. We've conducted one, and the University of California at Berkeley has conducted another one. I think the UN has several studies. Of course it's difficult to interview minors and children, and the studies are secondary in the sense that you go in and you look at families to see what's happened.
Oftentimes these children are more vulnerable than other children in the family because of the stigma associated with the rape. Oftentimes they're not accepted back by the fathers or the husbands and by the parents, which means that often these children are not able to go to school or even nutritionally receive the same food within a household.
This is why it's really important to have programs that address the specific vulnerability for these children, and again why we're focusing on this and why we're trying to encourage others to do so as well.
