Authorship and Originality

Originality

The author must ensure that they have written and submitted an entirely original work to the editorial board. All submissions are checked by an automatic plagiarism detection tool, subject to human review.

Authorship should be limited to individuals who have made a significant contribution to the conception, design, execution, or interpretation of the research study. All persons who have made a substantial contribution to a given scientific study should be listed as co-authors. In cases where other individuals have participated in certain essential aspects of a research project, their contribution should be acknowledged, or their names should appear in a list of contributors. The corresponding author must ensure that the manuscript includes only all genuine co-authors, and that all co-authors have reviewed and approved the final version of the manuscript and have given their consent for its submission for publication.

AI tools may not be credited as authors (see Use of Artificial Intelligence Systems below).

Referencing Sources

The use of works and/or phrases from other authors must be carried out in accordance with good academic practice, and such quotations must be clearly identified as such in the appropriate manner (see Guidelines for bibliographic references and citations).

Information obtained from third parties that has not been made publicly available – for example, information received in private communication, such as during a conversation, correspondence, or discussion with others – may under no circumstances be used or published without the explicit written permission of the source of that information.

Information acquired in the course of providing confidential services, such as the peer review of manuscripts or project documentation for funding purposes, may likewise not be used in any way without the express written consent of the author of the material involved in those services.

Use of Artificial Intelligence Systems

Any use of artificial intelligence (AI) systems for assistance – including for data processing, text editing, data visualisation, bibliography formatting, and similar purposes – must be declared and described in detail at the time of the manuscript’s initial submission. Declarations must include the name of AI tool(s), version(s), and description of what the tool did (what task(s) with what extent). IEUSConf uses STM’s Recommendations for a Classification of AI Use in Academic Manuscript Preparation (2025) to help authors define, evaluate, and disclose different kinds of AI contributions in preparing academic manuscripts.

The author remains solely responsible for the quality of all submitted textual and other materials. To avoid any doubt, the presence of false data or statements, inauthentic sources, omissions, inconsistencies, or any other flaws or deficiencies in the submitted texts and/or materials constitutes grounds for immediate rejection of the manuscript and for referral to the relevant ethics bodies.

The author may not claim authorship of any scholarly text, data, plans, or similar materials that have been created, in whole or in part, through the use of generative AI systems. The submission of entirely or partially automatically generated texts or materials for publication in the journal is strictly prohibited.

Submissions and/or Publication of the Same Manuscript in Multiple Journals

The author may not publish manuscripts containing identical or substantially similar text, or describing the same aspects of a single research study, in more than one journal or as the same primary publication. The author must not submit for consideration in another journal any material that has already been published.

The journal’s editorial board must give explicit authorisation in cases of a secondary publication, which must accurately reflect the same data and interpretations as those contained in the primary document. The secondary publication must include a reference to the primary source. 

The above paragraph does not apply to cases of secondary publication through deposit in a non-commercial repository (so-called “green Open Access”) under Article 60, paragraph 2 et seq. of the Bulgarian Copyright and Neighbouring Rights Act (CRRA) and Article 80, paragraph 2 of the Law on the Promotion of Scientific Research and Innovation (LPSRI).

Submitting the same manuscript simultaneously to more than one journal also constitutes unethical behaviour in scholarly publishing and is not permitted.

The above rules likewise apply to translations of the primary publication into another language.
