The editorial process consists of 6 stages:

1. Reception of the manuscript (indeterminate, depending on whether the author meets the requirements): its objective is to verify that the manuscript complies with the specifications of these instructions for authors and that the submitted documentation is complete.

2. Initial editorial review (maximum 5 business days): its objective is to corroborate the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical soundness of the study. At this time, it will be submitted to an electronic plagiarism detection system. Derived from this, a rejected opinion may be obtained, or it will be sent for review by peer researchers.

3. Review by peer researchers (maximum 30 business days): the opinion of at least two experts in the area in question will be obtained, who will evaluate the technical and methodological aspects of the investigation.

4. Editorial review (maximum 7 business days): its objective is to make a decision based on the opinion of peer reviewers. The opinion can be rejected, major changes, minor changes or accepted. In the case of major or minor changes, it will be submitted again for evaluation by the initial peer reviewers.

5. Final edition (6 weeks): its objective is the technical and linguistic edition (and translation), layout of galleys, DOI assignment, and correction by the author.

6. Advanced publication: All manuscripts will be published ahead of print on the journal's website as soon as they complete the editing process, until they are incorporated into a final issue of the journal.



The corresponding author will receive proofs of the article for revision and correction of terminology errors, or any other updates related to facts/figures. As the article will already have been edited according to the journal’s internal editorial guidelines, style corrections will not be accepted. The corresponding author will receive an email with the article in PDF format, on which they can leave their comments. Authors will need to have Adobe Reader (version 9, or a later version), downloadable for free). For other system requirements, please visit the Adobe website.
