As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.

  • The text has not been previously published, nor is it before another journal for consideration (or an explanation has been provided in Comments to the Editor).
  • The submission file is in OpenOffice, Microsoft Word, or RTF document file format.
  • The articles put forward for publication may be written in Catalan, Spanish, English, French or Italian. The Editorial Board can evaluate the inclusion of articles in other languages in very exceptional cases.
  • Authors must ensure that: the title of the article, the abstract and keywords are included in at least three languages (English, Spanish and Catalan), or four if the original language of the article is different from these three; the abstract consists of a maximum of 150 words each, organised in a single paragraph, without line breaks; and that 4 or 5 keywords are included.
  • All authors contributing to an original and their details (full name, place of work, e-mail address, ORCID - if this is not available, you can register free of charge at http://orcid.org -) are included in the first submission process. In this regard, authors must attach a Declaration of Authorship in the Comments to the Editor with their application. In this declaration, the authors must inform about the criteria chosen to decide the order of signature of the article, as well as the specific contribution of each of the authors to the article. The Declaration must be signed by each and every one of the authors. No additional authors may be added during the editing process unless there is good cause. The journal is not responsible for the authors that may have been omitted in the submission process.
  • The text is adapted to the stylistic and bibliographic requirements indicated in the Guidelines for Authors.
  • You must ensure, where necessary, that you have the permissions of the rights holders (individuals or institutions) for the publication of the illustrations.
  • Where available, URLs for the references have been provided.
  • Obligations that ensure that authors follow ethical principles in the scientific publication process must be accepted. The authors confirm that they meet the ethical COPE publication criteria or the DOAJ's Principles of Transparency and Best Practices in Academic Publishing.
  • The text is in Times New Roman font, size 12 for the text and size 10 for the notes, double-spaced; and all illustrations, figures and tables are placed in the appropriate places in the text, rather than at the end.
  • Bibliographic references must have a DOI link if they have one.
