This journal considers an author of a published work to be a person who has made a significant intellectual contribution to it. Following the guidelines of the Committee on Publication Ethics (COPE), to appear as an author the following requirements must be met:
1. Having participated in the conception and design, or in the acquisition of the data, or in the analysis and interpretation of the data of the work that has resulted in the article.
2. Have participated in the writing or critical review of the text.
3. Having approved the version that will finally be published.
Those who do not meet these three criteria can only be recognized in the acknowledgments. To avoid the risk of fictitious or usurped authorship, it is recommended that, at the time of sending the document, all authors agree on their contributions and the order in which they will appear in the list of co-authors.
To specify the contribution of each author to the work, it is recommended to use the criteria established by the CRediT taxonomy (Contributor Roles Taxonomy):
• Conceptualization – Ideas; formulation or evolution of the general objectives and goals of the research.
• Data Curation – Management activities to annotate (produce metadata), cleanse data, and maintain research data (including software code, where needed to interpret the data itself) for initial use and subsequent reuse.
• Formal analysis – Application of statistical, mathematical, computational or other formal techniques to analyze or synthesize study data.
• Acquisition of funds – Acquisition of financial support for the project leading to this publication.
• Research – Conducting an investigation and research process, specifically conducting experiments, or collecting data/evidence.
• Methodology – Development or design of the methodology; model creation.
• Project administration – Responsibility for management and coordination of the planning and execution of the research activity.
• Resources – Supply of study materials, reagents, materials, patients, laboratory samples, animals, instrumentation, computer resources or other analysis tools.
• Software– Programming, software development; computer program design; implementation of computer code and supporting algorithms; test existing code components.
• Supervision – Responsibility for supervision and leadership in the planning and execution of research activities, including external mentoring of the core team.
• Validation – Verification, either as part of the activity or separately, of the overall replicability/reproducibility of the results/experiments and other research products.
• Visualization – Preparation, creation, and/or presentation of published work, specifically data visualization/presentation.
• Writing – original draft – Preparation, creation and/or presentation of the published work, specifically the writing of the initial draft (including substantive translation).
• Writing – review and editing – Preparation, creation and/or presentation of the published work by the members of the original research group, specifically critical review, comment or review – including the stages before or after publication.
The contribution of each of the authorships will be stated at the end of the article in a note called 'Declaration of authorship contribution'. In the absence of this, the journal will apply 'Equal contribution' norm (EC)
To determine the order in the signature of the article, the authors can use any of the three most common practices:
• 'First-last-author-emphasis' approach (FLAE): the first signature and the last are equally important. Among them, it is considered that the order of signing indicates decreasing contributions.
• 'Sequence-determines-credit' approach (SDC): the order indicates the importance.
• 'Equal contribution' norm (EC): the alphabetic sequence is used to recognize similar contributions or to avoid disputes in collaboration groups.
The opinions and facts contained in each article are the sole responsibility of their authors, as well as the ethical suitability of the article. In addition, they must make it explicit that the text is their own and that the intellectual property rights of third parties are respected in it. It is also your responsibility to ensure that you have authorization to use, reproduce and print material that is not your property/authorship (charts, graphs, maps, diagrams, photographs, etc.). The authors, by submitting an article, accept that it is original and that it has not been submitted for consideration, nor has it been published in any other journal.
To eliminate name confusion and ensure ad attribution

To eliminate name confusion and ensure proper attribution of publications and citations correctly, this journal requires the ORCID ID for all authorship. Although it cannot by itself guarantee a secure identity, adoption of the ORCID is one more check against identity fraud by perpetrators.

changes in authorship

Any addition, deletion or rearrangement of names must be done before the manuscript has been accepted and only with the approval of the journal editor.

To request this change, the author will send to the editor:

the reason that justifies the request to modify the list of authors.
the written confirmation of all the authors expressing their agreement with the incorporation, deletion or rearrangement. In the case of the addition or deletion of an author, confirmation of the affected authorship must also be included.

In an already accepted manuscrit, the addition, deletion or rearrangement of authors will not be considered. If the manuscript has been published in an online version, requests for corrections also will not be considered.

Conflict of interest of the authors

The most easily identifiable conflicts of interest are economic relationships such as direct employment, payment for consultancies, participation in companies, fees, authorship of patents or payments for conferences. However, there may also be conflicts of interest arising from friendships, intellectual rivalries, academic competitions or beliefs. When submitting an article for publication, all authors are responsible for declaring any financial or personal relationship with any public or private entity that could (intentionally) influence the results of their work. Similarly, authors must declare any non-financial relationship that could cause a conflict of interest in their manuscript (personal, academic, ideological, intellectual, political or religious).

Conflicts of interest, both financial and non-financial, must be disclosed at the time the article is submitted. The idea is not to prevent authors with potential conflicts of interest from publishing; it is that such conflicts can be clearly identified, so that the readers can judge if the authors could be affected by some predisposition and this could influence the work.

A note called 'Conflict of interest' will be published at the end of the article. In case of absence, the note will show 'None'.
