Purpose: The number of retracted papers from Chinese university-affiliated hospitals is increasing, which has raised much concern. The aim of this study is to analyze the retracted papers from university-affiliated hospitals in China’s mainland from 2000 to 2021. Design/methodology/approach: Data for 1,031 retracted papers were identified from the Web of Science Core collection database. The information of the hospitals involved was obtained from their official websites. We analyzed the chronological changes, journal distribution, discipline distribution and retraction reasons for the retracted papers. The grade and geographic locations of the hospitals involved were explored as well.Findings: We found a rapid increase in the number of retracted papers, while the retraction time interval is decreasing. The main reasons for retraction are plagiarism/self-plagiarism(n=255), invalid data/images/conclusions(n=212), fake peer review(n=175) and honesty error(n=163). The disciplines are mainly distributed in oncology(n=320), pharmacology & pharmacy(n=198) and research & experimental medicine(n=166). About 43.8% of the retracted papers were from hospitals affiliated with prestigious universities. Research limitations: This study fails to differentiate between retractions due to honest error and retractions due to research misconduct. We believe that there is a fundamental difference between honest error retractions and misconduct retractions. Another limitation is that authors of the retracted papers have not been analyzed in this study.Practical implications: This study provides a reference for addressing research misconduct in Chinese university-affiliated hospitals. It is our recommendation that universities and hospitals should educate all their staff about the basic norms of research integrity, punish authors of scientific misconduct retracted papers, and reform the unreasonable evaluation system.Originality/value: Based on the analysis of retracted papers, this study further analyzes the characteristics of institutions of retracted papers, which may deepen the research on retracted papers and provide a new perspective to understand the retraction phenomenon. 展开更多

Recently, the editorial office received a requisition from one of the co-corresponding authors of an article published in Zoological Research in 2003. This researcher claimed he was not informed that he was listed as an author during the entire manuscript submission and publication process. Moreover, he had a concern about the reliability of the data in the paper. Therefore, he would like to withdraw his authorship of this particular article or withdraw this article entirely. The editorial office forwarded the letter to the other authors to collect comments, and the first author completely denied the co-corresponding author's claim of unawareness of authorship by providing archived emails between them. Setting aside what really happened 13 years ago, in this case, it may be interpreted that either this cocorresponding author himself is announcing his honorary authorship (either by passively being added to the byline or actively accepting the offer) in this article, or is trying to avoid taking (potential) responsibility regarding the research content by using honorary authorship as a defense. Meanwhile, the first author has been accused of offering honorary authorship to a senior researcher. 展开更多

Using the method of analogy, this paper built the social information field, information field force model and the information diffusion dynamics model to study the dynamic mechanism and the law of the movement regarding how misconduct information moves among nodes in the web forum. It also constructed the web forum misconduct information diffusion complex network simulation model to study the diffusion intensity of misconduct information and its influencing factors. The conclusion is that, under the force of the field, the information flows from the high potential node to the low potential node, during which resistance is generated inside and outside the diffusion channel. In the complex network of the web forum, the diffusion intensity of misconduct information displays an increasing trend as the possibility of reconnection among broken nodes becomes higher. The main factor that determines the diffusion intensity of the misconduct information is the average shortest path. It also increases when the interaction frequency turns higher. 展开更多

In recent years,academic misconduct has been frequently exposed by the media,with serious impacts on the academic community.Current research on academic misconduct focuses mainly on detecting plagiarism in article content through the application of character-based and non-text element detection techniques over the entirety of a manuscript.For the most part,these techniques can only detect cases of textual plagiarism,which means that potential culprits can easily avoid discovery through clever editing and alterations of text content.In this paper,we propose an academic misconduct detection method based on scholars’submission behaviors.The model can effectively capture the atypical behavioral approach and operation of the author.As such,it is able to detect various types of misconduct,thereby improving the accuracy of detection when combined with a text content analysis.The model learns by forming a dual network group that processes text features and user behavior features to detect potential academic misconduct.First,the effect of scholars’behavioral features on the model are considered and analyzed.Second,the Synthetic Minority Oversampling Technique(SMOTE)is applied to address the problem of imbalanced samples of positive and negative classes among contributing scholars.Finally,the text features of the papers are combined with the scholars’behavioral data to improve recognition precision.Experimental results on the imbalanced dataset demonstrate that our model has a highly satisfactory performance in terms of accuracy and recall. 展开更多

DEAR EDITOR: We read the publication by Liu (2016) on authorship misconduct with a great interest. In fact, the authorship misconduct is no uncommon and has to be managed, Liu (2016) noted that "Proper authorship embodies honesty, integrity, fairness and transparency, which surely are the very essence of any scientific pursuit." Due to the present requirement on academic publication to support academic rank, several forms of authorship misconduct can be seen. Of interest, 展开更多

Unethical behavior among university students such as cheating and plagiarism has weakened the character of honesty in education. This fact has challenged those who perceived education as a holistic process of internalizing values and norms that lead to the formation of students' moral principles and moral behaviour. Educators have played the role of ensuring the students to internalize and realized moral values and norms. A study of 360 students of the second semester who enrolled at the course of "ethical and personal development" at Atma Jaya Catholic University in Indonesia showed that unethical behavior such as cheating and plagiarism were rarely done. However, a deep look at the reason the students did academic dishonesty has prompted the permissiveness of student's moral life. This study proves that academic integrity among university students is worrisome, and it is worsened by the fact that they were enrolled in the course of "ethical and personal development". Seriously taking into consideration the strong desire of students to change the culture of academic misconduct, the authors argue that an educational model which is not oriented excessively to cognitive performance is needed. The authors argue that this position has to be practiced in line with the involvement of "clean" students who are involved as role models in influencing the formation of student awareness and ethical behavior. 展开更多
