PLAGIARISM AND ETHICAL MISCONDUCT
Journal of International Relations Studies is extremely sensitive about plagiarism. All submissions are screened by a similarity detection software (iThenticate by CrossCheck) at any point during the peer-review and/or production process.

Even if you are the author of the phrases or sentences, the text should not have unacceptable similarity with the previously published data. When you are discussing others' (or your own) previous work, please make sure that you cite the material correctly in every instance.

Authors are strongly recommended to avoid any form of plagiarism and ethical misconduct that are exemplified below.

Self- plagiarism (text-recycling): Overlapping sections or sentences with the author’s previous publications without citing them. Even if you are the author of the phrases or sentences, the text should not have unacceptable similarity with the previously published data.
Salami slicing: Using the same data of a research into several different articles. Reporting the same hypotheses, population, and methods of a study into different papers is not acceptable.
Data Fabrication: It is the addition of data that never occurred during the gathering of data or the experiments. Results and their interpretation must be based on the complete data sets and reported accordingly.
Data Manipulation/Falsification: It means manipulating research data with the intention of giving a false impression. This includes manipulating images (e.g. micrographs, gels, radiological images), removing outliers or ‘inconvenient’ results, changing data points, etc.

In the event of alleged or suspected research misconduct, e.g., plagiarism, citation manipulation, and data falsification/fabrication, the Editorial Board will follow and act according to COPE flowcharts.

Please check Table 1 for the limitations for Original Articles. For Turkish articles, authors must provide an English abstract, keywords, and extended abstract. For English articles, authors must provide a Turkish abstract and keywords.

Letters to the Editor: A "Letter to the Editor" is a type of manuscript that discusses important or overlooked aspects of a previously published article.

Readers can also use the "Letter to the Editor" format to share their comments on published manuscripts. The text of a "Letter to the Editor" should be unstructured and should not include an abstract, keywords, tables, figures, images, or other media. The manuscript that is being commented on must be properly cited within the "Letter to the Editor."

Book Reviews and Critiques: The journal welcomes reviews of contemporary and noteworthy books within the journal's scope, provided that they have been reviewed by an external expert on the relevant topic.

Please refer to Table 1 for the limitations of Book Reviews.

Table 1. Limitations for each manuscript type

*Word limit should not include the abstract, references, tables, and figure legends.

Tables
Tables should be included in the main document, presented after the reference list, and they should be numbered consecutively in the order they are referred to within the main text. A descriptive title must be placed above the tables in title case in italics. Abbreviations used in the tables should be defined below the tables by footnotes (even if they are defined within the main text). Tables should be created using the “insert table” command of the word processing software and they should be arranged clearly to provide easy reading. Data presented in the tables should not be a repetition of the data presented within the main text but should be supporting the main text.

Table Examples in APA Format

Figures and Figure Legends
Figures, graphics, and photographs should be submitted as separate files (in TIFF or JPEG format) through the submission system. The files should not be embedded in a Word document or the main document. When there are figure subunits, the subunits should not be merged to form a single image. Each subunit should be submitted separately through the submission system. Images should not be labeled (a, b, c, etc.) to indicate figure subunits. Thick and thin arrows, arrowheads, stars, asterisks, and similar marks can be used on the images to support figure legends. Like the rest of the submission, the figures too should be blind. Any information within the images that may indicate an individual or institution should be blinded. The minimum resolution of each submitted figure should be 300 DPI. To prevent delays in the evaluation process, all submitted figures should be clear in resolution and large in size (minimum dimensions: 100 × 100 mm).
