All copyrights remain with the author. The author grants The editorial office a free license to use the work under the Creative Commons terms. The publisher grants permission for the reprinting of the text published in the journal, provided that the original place of publication is cited.

All submitted typescripts are considered privileged information and have to be treated as such. Reviewers (also those who declined a review invitation) and editors are instructed to treat submissions in strict confidence, and are expected to maintain confidentiality of a typescript’s contents, except for its author, editorial staff and the editor, unless with the consent of the Editor-in-Chief. They are forbidden to reveal the information to anyone and in any form.

Reviews should be made objectively, and feedback should be clearly formulated so that authors can use it to improve their texts. Personal criticism of the authors is inappropriate.

Reviewers, to the best of their knowledge, should indicate published works that have not been cited by the authors.

The reviewer should notify the editors of any significant similarity of the typescript to any other text (published or unpublished) of which he has knowledge.

A reviewer who has a conflict of interest resulting from competition, cooperation or other relations or connections with any of the authors, organisations and institutions related to the typescript should immediately notify of the fact the Journal’s Editors.

Unpublished materials disclosed in the submission may not be used in the reviewer’s own research without the clear written consent of the authors.

Authors may be requested to provide (in digital form) the output data from the research together with the typescript for review. They should also be prepared to make data public, if possible. Authors should ensure that such data is available to other professionals for at least 10 years after publication, preferably through research data repositories (institutional or domain-specific).

The author of the article is considered to be the person who made a significant contribution either to the conception, or analysis and interpretation of the data; drafted the original typescript or revised it critically for important intellectual content; decided on the final version of the paper and agreed to its submission for publication. 

All persons who participated in the preparation of the text or the preceding research should be listed together with the nature of their contribution. The corresponding author should ensure that all co-authors have seen and approved the final version of the typescript and agreed to its submission for publication.

The contributed text has to adhere to the principles of ‘ghostwriting firewall’, based on the guidelines for academic journals. 

All disclosed cases of ghostwriting (hidden contribution by the authors or writing the text on request) and guest authorship (adding to the list of authors of people whose contribution to the text was negligible) will be made public on the websites of our Journal. The organisational unit employing the author will also be informed about this fact.

In justified cases, the Editorial Board may request a declaration of the author’s or authors’ contribution in accordance with the principles of the ghostwriting firewall.

Authors may be asked to submit a declaration on the sources of financial means for financing the publication, contribution from research institutions, associations and other entities (financial disclosure).

Any changes to the information about the authorship require the written consent of all interested parties. Such consent should be expressed by each of them separately, in an e-mail addressed directly to the Editor-in-Chief of the Journal. The consent of each of the authors to change the information about the authorship of the submitted article or of an already published article must be in the form of a written statement.

In the event that the author hides the co-authors of the text or discloses guest authorship cases in already published articles, the possible costs of editorial changes shall be borne by the author of the publication.
