In the interest of ensuring that the journal's ethics policy is reflected in the final published versions, all manuscripts will include final declarations, most of which are mandatory in nature. These statements are described below:

1. Author contributions (mandatory for co-authored articles)

The contributions of each author must be clearly recorded according to the CRediT taxonomy, which includes 14 criteria to identify the roles played. Example:

Juan Suarez: conceptualization, formal analysis, research, resources, supervision, writing (original draft), writing (revision/proofreading).

You can consult the CRediT taxonomy at: https://credit.niso.org.

2. Funding (mandatory)

Any funding received by the authors must be declared, or, failing that, the absence of funding must be indicated.

3. Conflicts of interest (mandatory)

Authors must declare any conflict of interest that may have influenced the research or the contents of the manuscript, complying with the ICMJE format provided by the journal.

4. Ethical implications (mandatory)

If the research involves personal information, animal or human experimentation, or any other relevant ethical issues, these should be declared, and, if necessary, evidence of ethical approval or informed consents should be provided. Also, these ethical implications should be mentioned in the methodology of the manuscript, explaining how they were taken into account in the development of the research.

5. Declaration of use of artificial intelligence (AI)

If any generative artificial intelligence tools (such as ChatGPT) were used in the preparation of the article, the author must declare:

• The type of AI tool used.
• The purpose for which it was used.
• In which section of the manuscript it was applied.
• At what stage of the research was it used (e.g., Conceptualization/Planning, Execution/Technique, or Evaluation/Analysis).
• How the AI-generated content was reviewed and verified.

6. Acknowledgments (optional)

The authors may include acknowledgements to persons or institutions that have contributed significantly to the research or to the publication of the manuscript. However, since this is an acknowledgment rather than a dedication (as is sometimes included in graduate work or books), acknowledgements of a private, personal or general nature will not be accepted; acknowledgements should acknowledge the contribution of third parties who have actually contributed to or facilitated the research or the preparation of the manuscript.
