Authorship and Contributions Policy (CRediT)

Revista Científica El Capacho requires that the authorship of each article faithfully reflect who did what. Signing a work confers credit, but it also carries public responsibility for its content; the journal therefore asks that contributions be declared explicitly and verifiably, rather than inferred from the order of the names.

Authorship Criteria

An author is recognised as such where all four of the following conditions are met: having made a substantial contribution to the conception or design of the study, or to the acquisition, analysis or interpretation of the data; having taken part in drafting the manuscript or in critically revising it with relevant intellectual input; having approved the final version submitted for publication; and accepting responsibility for the integrity of the work as a whole, undertaking that questions relating to the accuracy of any part will be investigated and resolved.

Anyone meeting only the first criterion is not an author. Obtaining funding, routine data collection, the administrative supervision of a group or the mere holding of a post do not in themselves constitute authorship. Such contributions are recognised in the Acknowledgements.

Contribution Statement under CRediT

Every manuscript must include a contribution statement drawn up using the CRediT taxonomy (Contributor Roles Taxonomy). The statement is placed at the end of the text, before the reference list, and is published in full in the final article. Each signatory must be assigned at least one role, and the same role may correspond to several people.

The fourteen roles of the taxonomy are as follows:

Conceptualization: formulation of the ideas, aims and overarching research goals.
Data curation: management, annotation, cleaning and maintenance of the data for initial use and later reuse.
Formal analysis: application of statistical, mathematical, computational or other techniques to analyse the data.
Funding acquisition: securing the financial support that made the project possible.
Investigation: conducting the study, in particular running the experiments or collecting the data.
Methodology: development or design of the methodology and creation of the models used.
Project administration: management and coordination of the planning and execution of the work.
Resources: provision of materials, reagents, instruments, patients, samples or other analysis tools.
Software: programming, code development, implementation and testing of the computational components.
Supervision: leadership responsibility and oversight of the execution of the research, including mentorship of the team.
Validation: verification of the reproducibility of the results and of the overall reliability of the experiments.
Visualization: preparation and presentation of the published work, in particular figures and data visualisation.
Writing — original draft: preparation and writing of the initial draft of the work.
Writing — review and editing: critical review, commentary and correction of the text at any stage.

Example statement: "Conceptualization: A. P.; Methodology: A. P. and B. R.; Formal analysis: B. R.; Investigation: B. R. and C. S.; Writing — original draft: A. P.; Writing — review and editing: A. P., B. R. and C. S.; Supervision: A. P."

Corresponding Authorship

The manuscript must identify the person responsible for correspondence, who acts as the point of contact with the journal throughout the editorial process and after publication. This person warrants that all signatories have approved the version submitted and the contribution statement, and is the recipient of the requests for access to data provided for in the Open Data Policy.

Order of Authorship and Changes

The order of signature is agreed among the authors and should reflect their level of participation. The journal does not intervene in that agreement, but neither does it accept unilateral changes to it.

Any change in authorship after submission —adding or removing a person, or altering the order— requires a request to the editorial team explaining the reason for the change and carrying the express written consent of everyone affected, including the person being added or removed. Requests made after acceptance will be considered with particular caution and, if accepted once the article has been published, will be recorded through a public corrigendum.

Group Authorship and Collaborations

Where the work originates from a group or consortium, it may be signed with the collective name, provided that the individuals taking responsibility for the content are named and that the full composition of the group is listed in the article. Those named must meet the authorship criteria and declare their CRediT contributions.

Practices Not Accepted

The journal rejects and treats as a breach of publication integrity honorary or courtesy authorship, consisting in including someone who has not contributed substantively; ghost authorship, which omits someone who did contribute; the sale, purchase or transfer of authorship positions; and the inclusion of a person without their knowledge or consent. Where any of these practices is detected, the manuscript is rejected or, if already published, the Retraction Policy is applied, with notification to the authors' institutions where appropriate.

Artificial Intelligence and Authorship

Generative artificial intelligence tools cannot be listed as authors, because they cannot assume public responsibility for the content or approve a final version. Their use must be declared under the terms of the Artificial Intelligence Use Policy, in a section of its own and not as a CRediT role.

Entry into Force

This policy applies to manuscripts received on or after its date of publication. Submissions already in the editorial process on that date continue to be governed by the conditions in force when they were received.
