University of Lleida's Academic Regulations on Doctoral Courses

Article 28. Theses submitted as papers

28.1 At the time such a doctoral thesis is submitted, it must contain at least four papers, of which at least two must have been published or accepted. Proof of such must be submitted with the thesis that the academic committee of the doctoral programme is to review.

28.2 Only papers published less than four years before the submission of a thesis will be accepted, in which the trainee researcher must be the first or second author. Of the articles published or accepted, at least two must have been published in journals that occupy relevant positions (quartiles 1, 2 and 3) in the science or social science editions of the Journal Citation Reports. Likewise, journals will be accepted that occupy the same quartiles on the portal SCImago Journal & Country Rank according to subject category, as well as journals found on databases such as the Science Citation Index (SCI), Social Science Citation Index (SSCI), Arts & Humanities Citation Index (A&HCI), Scopus and the Carhus plus lists (A or B). A document must be submitted to the thesis supervisor describing the status of each of the papers (published or accepted) and the impact index of each of the papers that form part of the thesis.

28.3 Papers that have co-first authorship may not form part of a doctoral thesis. In the case of co-authorship, the trainee researcher must provide a document signed by the other authors of a paper in which the following appears:

- a declaration stating that the paper has not been included in any other doctoral thesis

- an authorisation from the co-authors who are not PhD holders for the trainee researcher to include it in her/his thesis



When submitting the thesis online, it is necessary to provide the declarations and resignations of the co-authors of the articles that are part of the thesis:
