The language of submission and publication is English. Contributors whose native language is not English should have their manuscripts read by a native speaker before submission. Authors are required to submit abstracts in both English and their mother tongue. Occasionally, an article may be submitted in the author’s mother tongue provided the topic is particularly relevant for the language in question and that title, abstract, keywords and all bibliographical references are given in English.

Each submission must be accompanied by a short biographical note on the author(s), between 100 and 150 words, including affiliation and address of correspondence.
