One of the largest publishers of scientific journals is retracting 60 papers after an internal investigation found that they had been part of an orchestrated ring of fraud. In a statement released last week, Sage Publications said that it had uncovered a series of papers published in the Journal of Vibration and Control between 2010 and 2014 that had been sent to be peer reviewed by people using false identities. Sage believes that the ring is centered on the work of Peter Chen, from the National Pingtung University of Education, and potentially others from his university. In a statement to Retraction Watch, Sage explains that it uncovered at least 130 email accounts used to circumvent its system of peer review.
