 So, Dr. Mangold, thank you very much for attending the conference. You have been investigating crowd-working and data privacy as a lawyer. So what are the results of your first empirical study? First of all, I think our study showed that German crowd-working platforms partly provide detailed information about the collection of personal data. But we also have to say that there is a great need for further research to get more information about this very important issue of privacy aspects of crowd-working. And this conference is very interdisciplinary, so we have economists, lawyers, information systems people. Why do you think that they should talk to each other? I think it is absolutely necessary that different disciplines come together and to find solutions for the problems that exist because of this phenomenon of crowd-working platforms. And do you think there should be also new regulation or new laws implemented because we are generating all this new data and we have this new phenomenon of crowd-working? And how should it look like? So I think one important aspect in this regard is that the legal status of crowd-workers is unclear at the moment. So we don't know whether crowd-workers are employees or are they self-employed. So maybe one could think about to develop new concepts for an employee data protection law beyond the traditional employee protection law. Thank you very much.
