EDITORIAL PROCESS

The editorial process consists of 6 stages:

  1. Manuscript receipt (timeframe varies depending on the author’s compliance with requirements): The goal is to verify that the manuscript meets the specifications of these instructions and that the submitted documentation is complete.
  2. Initial editorial review (maximum 5 business days): The goal is to confirm the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical rigor of the study. At this stage, the manuscript will undergo an electronic plagiarism detection system. Based on this, a decision to reject or send the manuscript for peer review will be made.
  3. Peer review (maximum 30 business days): At least two experts in the field will evaluate the technical and methodological aspects of the research.
  4. Editorial review (maximum 7 business days): The goal is to make a decision based on the peer reviewers’ opinions. The decision may be rejected, major revisions, minor revisions, or accepted. In the case of major or minor revisions, the manuscript will be resubmitted to the initial peer reviewers for reevaluation.
  5. Final editing (6 weeks): The goal is technical and linguistic editing (and translation), galley proof layout, DOI assignment, and author corrections.
  6. Advance 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.



PROOFREADING (PDF) OF YOUR ACCEPTED ARTICLE

The corresponding author will receive the proofs of the article for review and correction of terminology errors or other updates related to data/figures.
