There are still six places available to a two-day post-WCSJ2013 study trip to the Estonian research centres in Tallinn and Tartu that the Estonian Association is organising together with the Estonian Research Council.
Here is some brief info on the WCSJ web site: http://wcsj2013.org/post-conference-exkursions/#6, and you can find a more detailed programme in the attached document. Feel free to send the information to your members — and consider taking the trip yourself if you are planning to come to the WCSJ in Helsinki.
Technically, this is not an EUSJA study trip, so you can register to the trip as a part of the registration process on the WCSJ site: http://wcsj2013.org/registration/. I understand that one can also register to the trip after having registered to the conference, by writing to firstname.lastname@example.org.
