Each submitted article is preliminarily reviewed, in order to verify if it fulfils the criteria of a scientific paper (the adequacy of the topic involved, the general organization of the article, the accuracy of the references etc.) and the publication guidelines (the general formatting, the author’s full name and affiliation, the abstract in a foreign language etc.). Each article accepted after this first selection is reviewed by two independent referees, selected according to their specific field of interest and to the article’s topic, within the „double blind peer-review” process (ensuring the authors’ as well as the referees’ anonymity). If necessary, the paper will be evaluated by a third referee, providing a differentiating review of the material. If the referees agree that the respective contribution fulfils the scientific criteria for being published, the author will receive in maximum four months the observations and the critical remarks; therefore, the author needs to send a new version of the paper, revised. This one will be verified again by a member of the editorial board. If the referees agree that the respective contribution does not fulfil the scientific criteria for being published, they send a report to the author, in which they explain their decision.
