Our Journal rejects any material that breaks legal requirements regarding plagiarism!

According to the standards of the prevention and detection of academic plagiarism in the scientific and educational papers of employees and candidates for higher education of the V. N. Karazin Kharkiv National University, before submitting the current issue of the Journal to the academic council of the faculty, the editorial board should check all papers accepted for publication. After this, an official conclusion should be prepared about the absence of plagiarism in this issue of the Journal. This conclusion must be signed by the Editor-in-chief.

Variations of plagiarism are:

• copying and publication of papers by other authors;
• verbatim copying of fragments of the text (from a phrase to a set of sentences) from someone else's paper without proper references;
• making minor corrections to the copied material (reformulation of sentences, changing the order of words in them, etc.) without proper quoting;
• excessive use of paraphrases. Paraphrase is a retelling of other people's thoughts, ideas, or text in your own words. The essence of the paraphrase consists in the replacement of words (signs), phraseological units or sentences in the use of any author's scientific paper (stored on electronic or paper media, including posted on the Internet).

The presence of plagiarism in the submitted materials can be checked with the help of the appropriate software and some web-services (like Plagiarism Detector and Grammarly).

The main systems for detecting plagiarism are Strikeplagiarism.

Plagiarism after publication. Procedure for retracting published articles

If plagiarism is detected after publication, the Journal will conduct an investigation. If plagiarism is found, the journal editorial office will contact the author's institute and funding agencies.
