PUBLICATION ETHICS & MALPRACTICE STATEMENT

Publication ethics are kept in the course of publication processes in Gazi Journal of Engineering Sciences (e-ISSN 2149-9373) to assure the best practice guidelines and hence it is crucial for the journal’s editors, authors, and peer reviewers to abide by the ethical policies. Gazi Journal of Engineering Sciences conforms to the principles below that are described by COPE’s Code of Conduct and Best Practice Guidelines for Journal Editors (https://publicationethics.org/resources/code-conduct) and not only transparency principles, but also best practice in scholarly publishing pointed out by the Committee on Publication Ethics (COPE).

Objectivity:
Editor-in-chief & section editors of the journal are account for deciding which of the manuscripts submitted to the journal ought to be published. In this process, the authors of the manuscript are not distinguished based on his/her race, ethnicity, gender, religion and citizenship by the editors. Editors´ decision to accept, revise or reject a manuscript for publication should be based merely on the importance, originality and clarity of the manuscript, and also convenience of the study performed in manuscript to the coverage of the journal.

Confidentiality:
Editor-in-chief and section editors staff must not reveal any information about a submitted manuscript to anyone but the corresponding author, reviewers/potential reviewers and the publishing personnel. Editors will assure that all material submitted by authors remains confidential during the review process.

Conflicts of interest & Disclosure:
Unpublished materials disclosed in a submitted manuscript must not be utilized in any reviewers’ own studies without express written permission of the author. Exclusive information or opinions attained from peer review process must be maintained confidential and not used for personal benefit. Reviewers ought not to take into account manuscripts in which they have conflicts of interest deriving from competitive, collaborative or other relationships/connections with any of the authors, companies or institutions linked to the articles.

Peer review process:
The editor-in-chief/section editors must assure that a double-blind peer review process is effectively performed for each manuscript submitted to the journal system.
Management of unethical behaviour(s)
Before being sent a manuscript to reviewers, it is checked in terms of similarity by iThenticate and similar applications to explore the plagiarism. If the similarity rate is over 20%, the article is directly rejected and returned.
The editors, together with the publisher(s), should take rationally responsive measures when ethical complaints have been presented regarding a submitted manuscript or published article.

DUTIES OF AUTHOR(S)

Authorship of the paper:
Authorship should be narrowed to those who have made a vital contribution to the reported study including conception, execution, design and interpretation. All authors made significant contributions to the submitted manuscript should be listed as co-authors.

Originality and plagiarism:
The authors are responsible for the content, language and originality of the manuscript they submitted. The authors should assure that they have composed their original works entirely, and if the authors have used the study and/or words of other authors, that this has been conveniently cited or quoted. Plagiarism takes many forms varying from “passing off” someone´s paper as the authors’ own paper to copying or paraphrasing important parts of someone´s paper (without attribution), to claiming results from research performed by others. Plagiarism in all its forms comprises unethical publishing behaviour and is inadmissible. Before being sent a manuscript to reviewers, it is checked in terms of similarity by iThenticate to explore the plagiarism.

Acknowledgement of funding sources:
All funding sources for the research reported in the manuscript should be acknowledged thoroughly at the end of the manuscript before references.

Disclosure and conflicts of interest:
All authors should reveal in their manuscript any financial or other substantive conflicts of interest which may be construed to affect the findings or interpretation of their manuscript. All financial support sources for the project should be disclosed as well. Disclosed examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Potential conflicts of interest should be declared at the earliest stage possible.

Reporting standards:
Authors of the manuscript should present an accurate explanation of the study conducted and an objective discussion of its importance. Underlying data should be accurately given in the manuscript. A paper should include sufficient detail and references to allow other researchers to repeat the study. Tricky or knowingly imprecise statements form unethical behaviour and are unacceptable. Review and professional publication articles should also be precise, original and objective, and editorial opinion works should be described overtly as such.

Data access & retention:
Authors might be asked to ensure the raw data in connection with a paper for the editorial review process, and should, in any event, be prepared to keep in such data for a moderate time after publication.

Multiple, redundant or concurrent publication:
Submitted manuscripts must not be under consideration of any other journal. Submitting the same manuscript to more than one journal concurrently comprises unethical publishing behaviour. The authors must also assure that the article has not been published elsewhere before.

Principal errors in published studies:
When an author corresponds to a significant error or inaccuracy in his/her own published work, it is the author´s obligation to notify swiftly the journal editor or publisher and cooperate with the editor to withdraw or correct the paper.


DUTIES OF REVIEWERS
Reviewers should review and send the review comments in the due time period. If the manuscript is not in the reviewer’s field of interest, then the manuscript must be sent back to the editor so that the other reviewers can be assigned without losing time.

Contribution:
Reviewers are the main members contributing to the quality of the journal being a peer-reviewed one. The reviewers who feel unqualified to review the received manuscript must swiftly notify the editor and reject to review that manuscript.

Confidentiality:

Objectivity standards:
Reviews should be objectively performed. Personal criticism of the author is unsuitable. Referees should frankly express their aspects with supporting arguments.

Acknowledgement of sources:
Reviewers should describe relating published study which has not been cited by the authors. Any statement that an observation, derivation, or argument had been previously reported should be accompanied by the relevant citation. A reviewer should also point out to the editor’s attention any vital resemblance or coincide between the manuscript under consideration and any other published paper of which they have personal information.

Disclosure & conflict of interest
Reviewers should not take into account the manuscripts in which they have conflicts of interest derived from competitive, collaborative, or other relationships/connections with any of the authors, companies or institutions linked to the manuscripts.
