Authorship contributions policy

In accordance with good editorial practice for the publication of scientific journals, an "author" of a published work is considered to be a person who has made a significant intellectual contribution to it. In this journal, authors are asked to indicate, when they have not contributed equally, the degree of contribution of each author in a section entitled "Contributing authorship" located at the end of the article, before the list of bibliographical references.

The list of authors should include only those persons who have contributed intellectually to the development of the work. Having helped in the collection of data or having participated in some technique are not in themselves sufficient criteria to be listed as an author. The author of an article must have participated in a relevant way in the conception and development of the article in order to assume responsibility for the contents and must also agree with the final version of the article. In general, the following requirements must be met in order to be listed as an author:

1. Have 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 in question, and
2. Have been involved in the drafting of the text and any revisions, and
3. Have approved the version that is finally published.

This journal declines any responsibility for possible conflicts arising from the authorship of the papers it publishes. follows the decision tree recommended by COPE in the case of a request for a change of authorship of a manuscript received or of an article already published (http://publicationethics.org/files/Spanish%20%281%29.pdf).
