Hi all,
Thanks for all of you who answered. The survey has now ended and I have started to analyze the results that I got quite a lot. Hopefully I can come back with the results in a few weeks.
This is truly an university survey, and I apologize that I haven't been able to comment anything here lately. That is because I went abroad for some weeks and right after that I have been on my summer vacation, also abroad. But as I said, I try to come back with some results for you in a short time. But as this is an university survey, and there is a summer break in our university right now, there will be real progress in the research not until September.
Sorry for the inconvenience.
