This subject is the title of an ongoing research at the AMA. Actually 4 students are involved and we are looking for more ideas, helping hands, but above all, a great thesis topic for you! There is a lot to tell about this topic, so if you are interested in the subject take contact with me "werner.jacobs@hzs.be" for detailed information. I will bring you in contact with the students who are actually working on the topic, so they can share their experience with you.
