The second situation is that there is serious self-plagiarism in the paper. Self-plagiarism refers to the author's repeated use of his research results in many papers and publications, without enough labeling and citation. Although these contents are original by the author himself, from the perspective of academic integrity, this kind of behavior is not allowed. Therefore, a paper with self-plagiarism may also be withdrawn.
The third situation is that the paper has the behavior of manipulating the duplicate checking system. Some improper academic actors will bypass the detection of duplicate checking system by modifying the character coding of papers and adding junk words. This behavior is not only a serious challenge to academic integrity, but also a destruction of the duplicate checking system. Once discovered, the relevant institutions will take severe measures, including revoking the qualification to publish papers.
To sum up, the withdrawal of papers is caused by plagiarism, self-plagiarism and manipulation of the duplicate checking system. In order to avoid the rejection of papers, graduate students should always keep in mind the importance of academic integrity, write and quote papers in strict accordance with the norms, and avoid any academic misconduct. In addition, the academic community needs to strengthen the supervision of the withdrawal of papers, establish a more perfect review and audit mechanism, and improve the quality of papers and academic integrity.
