Author Guidelines

Editorial Process

Siembra uses the Open Journal Systems (OJS) as its editorial management system, developed by the Public Knowledge Project (PKP). All manuscripts to be considered for publication must be submitted through this system.

Manuscripts should be submitted fulfilling the issues stated at the "Guide for Authors", The reception of manuscripts does not imply in any way a commitment of publication by the journal. Authors are responsible for including complete and correct information about the manuscript and its authors in the Metadata section.

Authors must include their ORCID iDs to encourage standardized criteria for authorship. If you do not have this iD, you can obtain it free of charge at: https://orcid.org/register 

Initially, the manuscripts will be received by a member of the Editorial Board, who will review manuscripts complies with the aim and scope of Siembra, as well as the journal's guidelines and the minimum quality criteria in terms of writing and content. This review will verify the level of originality by using specialized software (COMPILATIO, URKUND, Unicheck) and existing digital resources for this purpose.

If the manuscript complies with general conditions, it will be sent, in the second instance, to external reviewers, who will review it according to criteria of relevance, currency and importance, quality, clarity of expression and organization, and originality of the data included in the manuscript. The reviewers will recommend its:

• Rejection
• Major revisions
• Publication with minor revisions
• Publication without review

The authors will receive the reports of the scientific reviews anonymously. Once the manuscripts with corrections are received, they will be reviewed again by the external reviewers. We recommend to the authors the submission of their comments to the reviewers along with the revised manuscript, indicating the changes made and/or the aspects they consider not relevant to the observations made by the reviewers.

Siembra reserves the right to make style corrections and editorial changes that will be appropriate to improve the manuscript.

After the acceptance of the manuscript, the text will be formatted and a galley proof in PDF format will be sent to the authors for correction of typography and spelling only.
