Can the same publication in two journals can be tollerated? I was a bit surprised that yes according to the Czech Ethical Framework of Research (which is an official govt. document - https://www.msmt.cz/file/35847_1_1/) stating:
"Publication of similar (i.e. redundant) articles can be tolerated in the event that the author sent his/her manuscript to a publisher who for a long period of time made clear that he/she had not accepted and would not probably accept this work (for example the publisher did not communicate with the author). Therefore the author offered his/her work to another publisher although the work was, after all, accepted in both publishing houses and was published twice."
I am now wondering what is the definition of the poor journal communitation? For examples, can be a 3-months limbo of a submission accompanied with no response to author queries considered as a bad communication? It is not so uncommon in my experience...
