When looking at a researcher of today it is obvious that he/she is no longer staying at one university or other public or private research centre throughout his/her career, but is moving from one country to another, frequently and for shorter periods of time or is even working (be it sometimes under different statuses) in several countries at the same time. When the researcher of today retires his/her career path has been one of many different employers and can even be one of different statuses (employee, selfemployed,…).
