Ethical Principles and Publication Policy

The publication policy of the Universal Journal of Mathematics and Applications(UJMA) is based on the improvement and dissemination of information in an impartial and respectful manner. The processes applied in line with this policy directly affect the quality of the studies submitted by authors and affiliated institutions.

UJMA, adheres to national and international standards in research and publication ethics. It complies with the Press Law, the Law on Intellectual and Artistic Works, and the Higher Education Institutions Scientific Research and Publication Ethics Directive. UJMA has adopted the International Ethical Publishing Principles published by the Committee on Publication Ethics (COPE), Directory of Open Access Journals (DOAJ), Open Access Scholarly Publishers Association (OASPA).

The ethical duties and responsibilities listed below are based on the guidelines and policies published as open access by the Committee on Publication Ethics (COPE).

The publication of an article in a peer-reviewed journal is essential for the development of a coherent and respected knowledge network. Peer-reviewed articles support and develop scientific methods. Therefore, it is important for all relevant parties involved in the publishing process, including authors, journal editors, reviewers, and publishing agencies, to agree on the expected ethical behaviors and standards.

1. Ethical Principles

1. Authorship and Contributorship of the Paper

The stated study's authors should only be those who made a major contribution to its idea, design, implementation, or interpretation. Co-authors should be named for everyone who contributed significantly. The corresponding author is the person who adds everyone who contributed to the article according to their contribution rates and is responsible for viewing, approving, and accepting the final version of the article for publication.

Contributorship is the supporting process of article writers in obtaining scientific results. There are many different ways to contribute. For instance, , you can also contribute to an article as a co-author. You can also contribute by helping with a survey.

In all aspects of authorship and contributorship, we follow the COPE principles and recommendations.

2. Conflicts of Interest

Authors: All authors must disclose in their manuscripts any financial or other significant conflicts of interest that may affect some or all of their manuscripts. These explanations should be stated in the article information form.

Reviewers: Since the journal has a double-blind referee policy, referees cannot see the names of the authors. However, if referees suspect any conflict of interest in the article they are evaluating, they must withdraw from the refereeship of the article by informing the editor. In order to prevent conflict of interest, people in the institutions where the article authors are working cannot referee the article.

Editors: Editors must not have a conflict of interest with authors or reviewers. If the editor has any financial or financial support for the article, it should be disclosed. If the editor sends an article to the journal, the process of his article is closed to him until the article process is completed.

3. Journal Policies on Data Access, Sharing, and Reproducibility

It is highly encouraged by the Universal Journal of Mathematics and Applications (UJMA) that authors supply supplemental information and data sets that support the findings presented in their papers. When submitting a scientific manuscript, the editor should be informed of any constraints the author(s) may be subject to.

If the data do not breach human rights or other privacy concerns, UJMA invites the author(s) to share and make them publicly available publicly. Authors are required to cite any data used in their work. Whether the cited data sets were developed by the author(s) or not, they must be listed in the paper's reference list.

4. Data Fabrication and Falsification
Data fabrication: This is about generating research findings.

Data falsification: Manipulating research data to give a false impression. This includes manipulating images (eg, micrographs, gels, radiological images), removing outliers or "inappropriate" results, changing, adding, or skipping data points, etc. are included. Technically the Image can be improved for the readability of the images. However, if there is such an improvement, the editor should be informed when the article is sent to the journal and the article should also be included.

Proper technical manipulation means adjusting the contrast and/or brightness or color balance if applied to the full digital image (not parts of the image).

Improper technical manipulation means darkening, enhancing, deleting an image, and/or adding new elements.

5. Duplicate / Multiple Submission(s)

The papers that are submitted for publication must be original and have never been published before. Authors are required to cite previous work if they have used their own previously submitted or published work as the basis for a submitted paper. They should also indicate how new contributions in addition to previous work are presented in their submitted manuscripts.

6. Intellectual Property

• Authors certify that their submitted manuscript (and any supporting items) are their own intellectual property and the copyright has not been transferred to others.

• Authors attest that the paper complies with JSS authorship criteria and is free of plagiarism, fabrication, falsification, and manipulated citations.

• The author(s) retain ownership of all manuscripts, revisions, drafts, and galleys.

• All interactions, remarks, or reports from reviewers or editors will be kept confidential by authors, reviewers, and editors.

• With the exception of the final published galley(s), reviewers and editors agree to keep all manuscripts, changes, and drafts confidential.

7. Correction, Retraction, Expression of Concern

• If editors minor errors in the published article that do not have an impact on the conclusions, interpretations, or outcomes, they may make adjustments.

• If there are significant mistakes or violations that make the findings and results invalid, the editors may retract the paper.

• Editors may issue a statement of concern if there is a possibility of abusive research or publication by the authors, if there is evidence that the findings are unreliable and the authors' institutions have not investigated the incident, or if the potential investigation seems unfair or inconclusive. COPE and ICJME guidelines are taken into account with regard to the correction, retraction, and expression of concern.

8. Publication of Studies Based on Surveys and Interviews

Aiming to establish ethical assurance in scientific periodicals, UJMA journal adopts the principles of the "Code of Conduct and Best Practice Guidelines for Journal Editors" and the "Code of Conduct for Journal Publishers" published by the Committee on Publication Ethics (COPE). In this scope, the following aspects should adhere to the studies submitted to the journal:

• Ethics committee approval should be obtained for research conducted in all the disciplines that require ethics committee approval, and this approval should be stated and documented in the article.

• For studies requiring ethics committee approval, information regarding the approval (name, date and number of the committee) should be included in the Article Information Form at the end of the article.

The studies that require ethics committee approval are as follows:
• Any research conducted with qualitative or quantitative approaches that requires collecting data from participants.
• Studies conducted on humans,
• Retrospective studies in accordance with the law on the protection of personal data,
Also;
• A statement confirming that an "informed consent form" has been received in case reports,
• Obtaining permission from the owners for the use of scales, surveys or photographs belonging to others,
• A statement confirming that copyright regulations are met for the intellectual and artistic works used.

9. Policy of Publishing Additional or Special Issues

A special issue can be published in our journal once a year upon the request of the Editorial Board. The publication processes of the articles sent to be included in the special issue are the same as the standard processes.

• Additional or Special issue: An issue published in addition to the regular issues of a periodically published journal. It may consist of conference papers or a series of articles focusing on a specific topic.

• Page numbering in the additional or special issue is different from the regular issues.

• The print run of the additional or special issue cannot be more than one-third of the regular issue. The special issues containing conference paper abstracts are not included in this scope.

• Ratios of case reports, compilations, and research articles (excluding conference paper abstracts) published in the additional or special issue will be included in the ratios of articles published in other issues.

• The issues published as a tribute are not accepted as additional or special issues. Their page numbering and organization are the same as the regular issues.

Actions that violate scientific research and publication ethics are as follows:

(Turkish Council of Higher Education [YÖK] Scientific Research and Publication Ethics Directive, Article 4)

Plagiarism: Showing others' original ideas, methods, data, or works as their own work, partially or completely, without reference to scientific rules,

Forgery: Using data that does not actually exist or has been falsified in scientific research,

Distortion: Falsifying the research records or data obtained, displaying the equipment or materials not used in the research as if used, distorting or shaping the results of the research in the interests of the people and organizations that provide support,

Republishing: Presenting repetitive publications as separate publications in academic appointments and promotions,

Slicing: Dividing the results of research into pieces in an improper way or in a way that disrupts the integrity of the research and publishing each one separately to increase the total publication count for academic appointments and promotions,

Unfair Authorship: Including non-contributors in the author list or not including those who have contributed, changing the author's order in an unjustified and inappropriate manner, removing the names of contributors from the work in subsequent editions, using influence to include names among the authors despite not being contributors,

Other ethical violations include:

a) Not specifying the supporting individuals, institutions, or organizations and their contributions in the publications made as a result of research conducted with support.

b) Using theses or studies that have not yet been submitted or have not been accepted as a source without the permission of the owner,

e) Deliberately making a false and ungrounded allegation about the ethical violation,

f) Publishing the data obtained from surveys conducted as part of a scientific study without the explicit consent of the participants or without the permission of the relevant institution if the study is conducted in an institution,

g) Conducting research activities in violation of the related legislation or the provisions on research in the international conventions to which Turkey is a party,

h) Disregarding the obligation to inform and warn the relevant authorities about possible harmful practices related to scientific research.

ı) Not using the data and information obtained from other individuals or institutions in scientific studies to the extent and as permitted, not respecting the confidentiality of this information and not ensuring its protection,

i) Making false or misleading statements regarding scientific research and publications in academic appointments and promotions.
