Authorship Policy

1.    Authorship Criteria and Author Contributions Policy

Authorship should be limited to individuals who have made a substantial scholarly contribution to the conception, design, execution, data acquisition, analysis, interpretation, drafting, or critical revision of the manuscript. All authors must approve the final version of the manuscript before submission and must agree to be accountable for the integrity and accuracy of the work.

TUJNAS does not permit honorary, gift, guest, or ghost authorship. Individuals who contributed to the work but do not meet the criteria for authorship should be acknowledged in the Acknowledgements section, subject to their consent.

The corresponding author is responsible for ensuring that the author list is complete and accurate at submission, that all authors have approved the manuscript, and that all authors have agreed to the order of authorship. Any request to add, remove, or rearrange authors after submission must be justified in writing and approved by all authors and by the Editor-in-Chief.

For transparency, TUJNAS requires an Author Contributions statement for all accepted manuscripts. The statement should describe the role of each author, for example: conceptualization, methodology, investigation, data curation, formal analysis, writing-original draft, writing-review and editing, supervision, project administration, and funding acquisition.

 

2.    Conflict of Interest and Competing Interests Policy

Authors, editors, and reviewers must disclose any financial, personal, professional, institutional, or other relationships that could reasonably be perceived to influence the submitted work, editorial decision, or peer-review process. Potential competing interests include, but are not limited to, employment, consultancy, honoraria, grants, paid expert testimony, patent applications, stock ownership, personal relationships, academic competition, or institutional affiliations.

All manuscripts must include a Competing Interests statement. If no competing interests exist, authors must state: “The authors declare that they have no competing interests.” Where competing interests are declared, the statement will be published with the article.

Editors and reviewers must decline handling or reviewing manuscripts where a conflict of interest may compromise, or appear to compromise, objectivity and fairness.

 

3.   Funding Disclosure Policy

All authors must disclose all sources of financial support for the research and publication of the article. Funding statements should include the name of the funding agency, grant number, project number, institutional support, or any other financial contribution.

If the research received no specific funding, the manuscript must include the statement: “This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.”

Authors must also declare whether the funder had any role in study design, data collection, data analysis, interpretation, manuscript preparation, or the decision to submit the article for publication. If the funder had no role, this should be clearly stated.

 

4.   Data Availability and Reproducibility Policy

TUJNAS supports transparency, reproducibility, and responsible data sharing. All manuscripts reporting original research must include a Data Availability Statement. The statement should specify where the data supporting the findings of the study can be accessed, including repository name, DOI or persistent link, accession number, or conditions for access.

Authors are encouraged to deposit datasets in recognized public, institutional, or subject-specific repositories whenever ethically and legally possible. Where data cannot be shared because of privacy, confidentiality, ethical restrictions, security concerns, or third-party ownership, authors must clearly explain the restriction and provide information on how qualified researchers may request access when appropriate.

Data, code, materials, and protocols should be cited in the reference list when a persistent identifier is available. TUJNAS may request access to underlying data during peer review or after publication when necessary to verify the integrity of the research.

 

5.   Research Materials, Code, and Protocols Policy

Authors should provide sufficient methodological detail to allow independent verification and, where possible, replication of the work. For studies involving computational analysis, modeling, software, scripts, or specialized code, authors are encouraged to provide the code or workflow in a recognized repository and to cite it in the manuscript.

For laboratory and experimental studies, authors should describe materials, instruments, reagents, calibration procedures, statistical methods, and protocols with enough detail to support reproducibility. Any restrictions on access to materials, code, or protocols must be clearly stated.

 

6.   Use of Artificial Intelligence and AI-Assisted Technologies Policy

Authors must disclose the use of artificial intelligence tools, large language models, or AI-assisted technologies in the preparation of the manuscript, generation of text, editing, translation, image processing, data analysis, code generation, or any other part of the research or writing process.

AI tools and AI-assisted technologies cannot be listed as authors because they cannot take responsibility for the accuracy, integrity, originality, and ethical compliance of the work. Authors remain fully responsible for all content generated or modified with the assistance of AI tools, including the accuracy of references, data interpretation, and absence of plagiarism or fabricated content.

Where AI-assisted tools were used, authors should include a statement such as: “During the preparation of this work, the author(s) used [tool name and version] for [specific purpose]. The author(s) reviewed and edited the output and take full responsibility for the content of the published article.” If no AI tools were used, no statement is required unless requested by the journal.

 

7.   Corrections, Retractions, and Expressions of Concern Policy

TUJNAS is committed to maintaining the accuracy and integrity of the scholarly record. When errors are identified in published articles, the journal will determine the appropriate action based on the nature and seriousness of the issue. Minor errors that do not affect the findings may be corrected through a correction notice. Significant errors that affect interpretation may require a formal correction, editorial note, or further investigation.

Retractions may be issued when there is clear evidence that findings are unreliable because of misconduct or honest error, when the work has been published elsewhere without proper justification, when plagiarism is identified, or when unethical research is confirmed. An Expression of Concern may be issued when an investigation is ongoing and the reliability of the article is uncertain.

All correction, retraction, or expression-of-concern notices will be linked to the original article and will remain part of the permanent scholarly record.

 

8.   Appeals and Complaints Policy

Authors may appeal an editorial decision if they believe that a serious misunderstanding, procedural error, or factual mistake affected the decision. Appeals must be submitted in writing to the editorial office and must include a clear explanation and supporting evidence. Appeals based only on disagreement with reviewers’ opinions or journal priority will not normally be considered.

Complaints related to editorial process, publication ethics, conflicts of interest, peer review, or journal management will be handled confidentially and fairly. The Editor-in-Chief or an assigned senior editor will review the complaint and may consult the Editorial Board when appropriate. The journal’s decision after appeal or complaint review is final.

 

9.   Article-Level Transparency Statements Policy

Each published article in TUJNAS should include standardized transparency statements, as applicable. These statements should include: Author Contributions, Funding, Competing Interests, Data Availability, Ethics Approval, Informed Consent, Consent for Publication, Use of AI-Assisted Technologies, and Acknowledgements.

If a statement is not applicable, authors should state “Not applicable.” If there is nothing to declare, authors should provide a clear negative declaration, such as “The authors declare no competing interests.” This practice increases reader trust and aligns TUJNAS with international journal transparency standards.
