 Good afternoon. We're starting slightly late so we're going to have to try and catch up on time and we have such a very rich panel that I want to make sure that there's also some time for you to ask questions and share perspective. This is a session talking about measuring quality of life or measuring happiness, measuring the things that are important that we've been talking about this morning. So what we're going to do is something slightly different from what you've seen earlier in the day. We're going to invite the various speakers to address you or from the podium but once they've finished with their presentation we're going to actually bring a fleet of chairs up there so that you can see all the speakers and they can have a better conversation with all of you. If you look at the program we're going to start with Richard Senate and then we're going to follow on with several other speakers but without further ado let me make sure that we start as soon as possible. May I invite Richard Senate from the School Professor of Social and Cultural Theory Emeritus from LSE to address us.
