 Oh, my current PhD research is about Brazil, the role of Brazil in global postal communications. And what I see is that during the 19th century, Brazil made some effort to escape from the Bibilateral Postal Treaties model and to engage in a multilateral postal arrangement that is emerging with the UPU. And this is the scope of my presentation today and is also the scope of my ongoing research agenda. I don't know if it changed something for the public in general, because as statistic data shows me, the volume of correspondence between Brazil and places in Europe and United States remains the same, but I think UPU set some arrangements, particularly accountability arrangements that implied in an undepthedness, crescent undepthedness of Brazilian postal system in relation to UPU and especially French postal system. That is the thing that statistical and financial data shows me that I need to go further in my research in order to understand this undepthedness.
