The statement
“It has done away with the position of editor-in-chief. Staffers in Cairo make accept/reject decisions based on reviewers’ comments (with the exception of issues with guest editors)”
in the last paragraph is not exact.
Journals have no Editor-in-Chief while they have a set of Editors to handle the regular submissions . Editors handle the papers assigned to them and choose the referees to start the refereeing process before taking the editorial decision upon reception of the referees´ reports. Also, the assigned editor can reject directly assigned papers , by justified reasons that he /she has to point out, before starting the standard refereeing process.
