About the journal




The journal DELTA: Documentação de estudos em linguística teórica e aplicada is published by São Paulo Catholic University (Pontifícia Universidade Católica de São Paulo; PUCSP). The journal has been published regularly since 1985, in four yearly issues. Since 2011, publications are exclusively online and since 2021 it has been adapting its publication policies to Open Science Green practices. Authors should refer to the journal as DELTA.



Open Science policies


DELTA follows the Open Access Green practices.

As from February 2024, every author that wishes to submit a manuscript has to fill in a form consenting to open access green practices. Such form is available here and authors have to submit it together with the manuscript. Non-submission prevents the beginning of peer review.



Ethics in publishing


DELTA supports COPE practices. The journal does not accept original research done by its editors, to avoid conflict of interests. It also adopts policies to the use of AI and AI-assisted technologies in scientific writing. Such policies are laid out in the guidelines for authors. The software Turnitin is used to detect plagiarism and self-plagiarism after peer review and before the manuscript is published ahead of print in SciELO Preprints. Studies that involve human beings must submit approval by an accredited Ethics Committee together with the manuscript.



Aims and scope


The journal publishes original research from any area of applied and theoretical linguistics, theoretical or applied. Only new contributions will be considered.



Digital preservation


DELTA follows the standards defined by the SciELO program digital preservation policy.

Editorial policies




If authors wish so, accepted manuscripts, whose final versions are being prepared for publication in an issue of DELTA, will be published at SciELO Preprints. Such manuscripts will receive a DOI to be cited as forthcoming. Manuscripts will be potentially accepted sooner if (1) they have already been hosted in a preprint server acknowledged by DELTA and (2) they have followed some of the suggestions given by peers in the preprint server.



Editorial aim and policy


DELTA: Documentação de estudos em linguística teórica e aplicada publishes original research from any area of applied and theoretical linguistics. Only original unpublished contributions will be considered.

Submissions must fit into one of these categories: Article, Debate, Squib, Overview (critical overview of the state of the art), Book Note and Reviews.

Researchers from countries around the world are invited to submit their papers which will be sent to two anonymous referees from the Editorial Board. In the event of a tie, a third review will be called. If necessary, an ad hoc referee will be invited. Contributions can be submitted in Portuguese, English, or Spanish.



Peer review


DELTA adopts a continuous publication process. The journal reserves the right to reject submissions recommended by reviewers, given the availability of publication within a reasonable time frame. The journal receives a much higher number of submissions than the available spots in future issues. Recommended articles are selected for publication by the editors in view of internal criteria of academic excellence. The editor responsible for the submission will inform the authors of the decision to publish or not the submission recommended by the reviewers. The journal also reserves the right to reject submissions before sending them to reviewers (desk reject), in view of the scope of the work and its quality.

Peer review criteria:

  • compliance with guidelines to authors;
  • relevance and contribution to the area of knowledge;
  • theoretical consistency;
  • methodological consistency;
  • up-to-date bibliographical references;
  • consistency with technical standards.
  • idiomatic academic writing; If the author is not a native speaker of English, we strongly recommend that the manuscript be revised by a native speaker before submission. Non-idiomatic writing may cause your submission to be rejected.

After being submitted to the DELTA’s editorial board, the paper is assigned to an editor who will be in charge of the paper. The editor will determine whether the paper can continue to be evaluated. In case the paper is accepted by the editor, it will be forwarded to two referees. Otherwise, the submission will be desk rejected. In case of contradictory reviews, a third referee will be chosen by the editor to evaluate the paper. The editor has the final word on whether or not the manuscript is accepted. In addition to the reviewers, the editor will take other parameters into account to determine whether or not the paper can be accepted for publication. Papers recommended by referees are not automatically accepted.

Reviewers will be kept anonymous throughout the entire editing process of the work and after its publication. During the submission/editing process, authors will also be kept anonymous. To this end, upon submission, the author(s) must replace any self-citation or co-author citation of the author by XXXXXX, 0000, page ???. In the References section citations must be replaced by. Only after the work has been accepted, the author(s) must complete the anonymized citations.

Manuscripts that have a preprint version, on a platform recognized by DELTA, will be evaluated by one of the journal's editors and may be approved without having to be peer reviewed once more. To that end, the manuscript submitted to DELTA must include a link to its preprint version before the title. The manuscript must be accompanied by a supplementary document with the changes that were made to the preprint version.



Open access


DELTA follows the TOP guidelines to grant access to research data. Such guidelines are provided by SciELO. We reproduce some of these guidelines below.

SciELO. Guia de citação de dados de pesquisa [online, p. 6-7]. SciELO, 2018 [20 de janeiro de 2024]. Disponível em:

Policy on the Use of Artificial Intelligence in International Academic Journals


1. Introduction:

The advancement of Artificial Intelligence (AI) has introduced new capabilities and opportunities in the production and review of academic content. However, this innovation also poses ethical and technical challenges. This policy guides the responsible use of AI in our publication, ensuring the integrity, transparency, and excellence of the research we endorse.

2. Use of AI in Manuscript Submission:

2.1. Authenticity and Originality: Authors employing AI to generate or analyze content must ensure that their work is original and makes a meaningful contribution to the field of study. Furthermore, authors should explicitly state the extent of AI's involvement.

2.2. Declaring the Use of AI: All manuscripts utilizing AI, be it in generation, analysis, or any other capacity, must clearly indicate this in the method and materials sections.

3. Use of AI in Peer Review:

3.1. Assistance, not Replacement: AI can be used to assist reviewers in identifying plagiarism, inconsistencies, or other technical issues. However, the final decision on a manuscript's acceptance remains a human responsibility.

4. Ethics and Responsibility:

4.1. Training and Bias: We recognize that AI algorithms can harbor unintentional biases. We commit to using models trained on diverse data sets and to regularly reviewing our systems to detect and rectify biases.

5. Policy Updates:

Given the rapid evolution of AI technology, this policy will be regularly reviewed to reflect current best practices and ensure that we continue to meet academic standards of excellence.

6. Conclusion:

We advocate for the ethical and transparent use of AI, believing in its potential to enrich academic research while upholding the integrity and trust in our publications. We encourage the academic community to join us in this commitment and to actively engage in the ongoing discussion about AI's role in academia.

Obs.: DELTA keeps the copyright of the papers submitted unless it officially withdraws this right on request. Papers submitted are not to be witdrawn after the process of refereeing starts.
