As you can imagine, we're trying to deal with people from different cultures and different parts of the world. The IRB has many mechanisms. First, we have an extensive new member training program, which provides for the assessment of evidence. It's not easy to do this type of evidence assessment. We have an extensive, internationally renowned research directorate, which provides objective and impartial evidence on conditions in the countries we deal with. The members have an ongoing professional development program, in which members and research officers who are dealing with cases from a particular country get together to make sure they are fully informed.
One of the challenges we've met very well is the issue of rapidly changing conditions in a country. We all read the paper and see how things happen. We try to make sure our members are fully supported and always up to date on the situations in these countries. It's a challenge, but it's one we have successfully met, one that I expect us to meet in the future. It's the core of what we do.
