  1. According to Erasmus (on twitter), there is a committee currently investigating the fraud. They are almost done investigating all Smeesters work and are mainly focusing on the research-culture now. They were unable to give an estimate of when they expected to be done.

  2. The first paragraph in english:
    The Erasmus University of Rotterdam has decided to continue research into all publications of former professor Smeesters. This is a result of continuing doubts within the scientific domain about these publications. The Erasmus Medical Center is studying possibilities to judge all publication of Poldermans. With these measures Erasmus University and Erasmus Medical Center want to create as much clarity as possible about the scientific worth of the work of both professors.

    In my opinion both these cases and the Stapel case reflect well on the persistence of Dutch universities to try and stamp out fraud. Hopefully other institutions will take this as a good example.
