Submitted manuscripts are not assigned directly to an editor. Instead, editors can decide to take up the responsibility of handling the review process of a paper on a purely voluntary basis. Sometimes an editor with a high expertise in the field of the submitted paper is found quickly through this process, but in other cases no-one on the editorial board takes responsibility for the manuscript, and it is in practice rejected by the secretarial office without giving the author any explanation or scientific justification for the decision.
