I haven't seen that directly. I will speak a bit on the first responder research basis, because we do have a fairly heterogeneous representation of research. There's much more research on police than there would be on fire, for example. Even within that group of first responders, it's difficult to understand their experiences.
There are some intersections between those who are releasing from the military and who then go on to do a public safety position as a second career. That's not an uncommon experience. Again, these are areas that are newer and that have not received a lot of research funding, so we have a lot of work to do there as well.
