Ethical Principles and Publication Policy
This guide was prepared by the Hagia sophia Journal of Geometry (HSJG) to draw attention to the compliance of publishers, editor-in-chief, editors, reviewers, and authors with ethical principles and scientific data. The editorial board follows the guidelines of the Journal Editors Practice Guide published by the International Ethical Principles and Publication Policy Publication Ethics Committee (Committee on Publication Ethics, 2011) and aims to maintain scientific integrity, transparency, and ethical practices across all phases of the publication process.

The journal routinely screen article submission for plagiarism.

Editor-in-Chief and Editors

  • Editor-in-chief and editors do not share information about the article with anyone except the author/authors, language, spelling, layout and other publication editors. Editors evaluate articles regardless of the author's/authors' ethnic origin, gender, nationality and religious beliefs.

  • Editor in chief and editors evaluate the article by paying attention to scientific and ethical values and make a final decision. It is the responsibility of the editor-in-chief and editors to take the necessary measures in order to select the reviewers suitable for the study, to have no interest relationship between the authors and the reviewers, and to evaluate the work by the reviewers in an impartial and scientific manner.

  • Editor-in-Chief and editors examine the publication according to the relevant rules with and make a decision if any situation contrary to publication ethics is detected or any situation is reported. If a contradiction is detected, it publishes a statement regarding this publication.

Reviewers

  • The reviewers evaluate the articles by paying attention to rules such as confidentiality, impartiality, conflict of interest, and ethical principles, without allowing the author' /authors' gender, religion, nationality to influence the assessment.

  • If the article reviewed article is similar to a previously published study, the relevant evidence should be reported by the reviewer and the situation should be reported to the editors.

  • If the reviewers notice quotations or methods used in the study without reference, they should inform the author. Articles are evaluated by at least two referees by applying blind refereeing.

Authors

  • Plagiarism, concealment of conflict of interest, plagiarism, forgery, distortion, duplication, slicing, unfair authorship, virtual or shadow authorship, gift authorship, honorary authorship are considered ethical issues.

  • Compliance of the articles with ethical rules is under the responsibility of the author / authors.

  • If dangerous substances or substances, unusual materials or procedures were used during the preparation of the scientific study sent to the journal, these issues should be explained in detail in the study.

  • If the subject, guinea pig, healthy or sick individual has been used in the scientific research, the reasons for use should be clearly stated.

  • It should also be ensured that all necessary permits have been obtained and that volunteerism is essential.

  • While conducting scientific research, sufficient and relevant resources should be given about the study.

  • The article sent to the journal must be original, it must not be published elsewhere before, and must not be evaluated elsewhere and in another language.

  • Each of the article authors must contribute significantly to the article, and the person or persons who do not contribute to the article should not be added to the article as an author.

  • No author additions or deletions are made while the article is being evaluated or after the article has been accepted.
