Elsevier has defined policies and ethical guidelines that have to be obeyed by authors and editors and Elsevier takes its duties of guardianship over the scholarly record extremely seriously. Upon investigation, the Editors of the Elsevier journals involved found that these concerns sufficiently compelling that they have decided that these papers should be retracted from the journals.
