6.5. Preprint Policy

The editorial board maintains an open position on preprints and supports the principles of open science. Authors may post their manuscript before, during, or after peer review on recognised preprint servers (SSRN, EconPapers, arXiv, Zenodo, OSF Preprints, etc.). When submitting a manuscript to the journal, authors must disclose any existing preprint version (server, URL, and date of posting). Following acceptance, the editorial board recommends updating the preprint record to include the DOI and full bibliographic reference of the published version. A preprint is not considered a prior publication and does not constitute grounds for rejection.

6.6. AI Use Statement

All authors are required to include a statement on the use or non-use of generative artificial intelligence (AI) tools in the preparation of the manuscript. This statement is mandatory for all submissions, regardless of whether such tools were used.

If AI tools were not used, the following statement must be included: «The authors did not use any artificial intelligence tools in the preparation of this work».

If AI tools were used, authors must specify: the name of the tool and version, the purpose of use (e.g., language editing, grammar checking, literature search), and the extent of use. Example: «During the preparation of this work, the authors used [tool name, version] for the purpose of [purpose]. The authors reviewed and edited the generated content and take full responsibility for the content of the publication».

AI tools may not be listed as authors or co-authors of the article. Responsibility for the accuracy, reliability, and originality of the content remains solely with the human authors.

Deliberate concealment of AI tool usage constitutes a violation of publication ethics and may result in rejection of the manuscript or retraction of a published article.

For further details, see the Journal's AI Use Policy.

7. Aсademic integrity

The editorial board categorically condemns any form of academic misconduct, including: plagiarism (including self-plagiarism); fabrication or falsification of data; duplicate publication; and improper authorship.

All manuscripts are checked for text borrowing using specialized software. Plagiarism is defined as the verbatim or paraphrased reproduction of another author’s text without proper citation, regardless of the extent of the borrowing.

Manuscripts showing signs of plagiarism are rejected at any stage. If plagiarism is detected in a published article, it is subject to retraction in accordance with COPE guidelines.

8. Grounds for Rejection Without Review
