Background: Plagiarism is considered as serious research misconduct, together with data fabrication and falsification. However, little is known about biomedical researchers' views on plagiarism. Moreover, it has been arguedbased on limited empirical evidencethat perceptions of plagiarism depend on cultural and other determinants. The authors explored, by means of an online survey among 46 reputable universities in Europe and China, how plagiarism is perceived by biomedical researchers in both regions. Methods: We collected work e-mail addresses of biomedical researchers identified through the websites of 13 reputable universities in Europe and 33 reputable universities in China and invited them to participate in an online anonymous survey. Our questionnaire was designed to assess respondents' views about plagiarism by asking whether they considered specific practices as plagiarism. We analyzed if respondents in China and Europe responded differently, using logistic regression analysis with adjustments for demographic and other relevant factors. Results: The authors obtained valid responses from 204 researchers based in China (response rate 2.1%) and 826 researchers based in Europe (response rate 5.6%). Copying text from someone else's publication without crediting the source, using idea(s) from someone else's publication without crediting the source and republishing one's own work in another language without crediting the source were considered as plagiarism by 98, 67 and 64%, respectively. About one-third of the respondents reported to have been unsure whether they had been plagiarizing. Overall, the pattern of responses was similar among respondents based in Europe and China. Nevertheless, for some items significant differences did occur in disadvantage of Chinese respondents. Conclusions: Findings indicate that nearly all biomedical researchers understand (and disapprove of) the most obvious forms of plagiarism, but uncertainties and doubts were apparent for many aspects. And the minority of researchers who did not recognize some types of plagiarism as plagiarism was larger among China-based respondents than among Europe-based respondents. The authors conclude that biomedical researchers need clearer working definitions of plagiarism in order to deal with grey zones.

Recent empirical evidence has demonstrated that research misconduct occurs to a substantial degree in biomedical research. It has been suggested that scientific integrity is also of concern in China, but this seems to be based largely on anecdotal evidence. We, therefore, sought to explore the Chinese situation, by making a systematic review of published empirical studies on biomedical research integrity in China. One of our purposes was also to summarize the existing body of research published in Chinese. We searched the China National Knowledge Infrastructure, Wanfang Data, PubMed and Web of Science for potentially relevant studies, and included studies meeting our inclusion criteria, i.e. mainly those presenting empirically obtained data about the practice of research in China. All the data was extracted and synthesized using an inductive approach. Twenty-one studies were included for review. Two studies used qualitative methods (interviews) and nineteen studies used quantitative methods (questionnaires). Studies involved mainly medical postgraduates and nurses and they investigated awareness, attitudes, perceptions and experiences of research integrity and misconduct. Most of the participants in these 21 studies reported that research integrity is of great importance and that they obey academic norms during their research. Nevertheless, the occurrence of research misbehaviors, such as fabrication, falsification, plagiarism, improper authorship and duplicate submission was also reported. Strengthening research integrity training, developing the governance system and improving the scientific evaluation system were areas of particular attention in several studies. Our review demonstrates that a substantial number of articles have been devoted to research integrity in China, but only a few studies provide empirical evidence. With more safeguard measures of research integrity being taken in China, it would be crucial to conduct more research to explore researchers' in-depth perceptions and evaluate the changes.

Background: Scientific researchers are expected to follow the professional norms in their own domain. With a growing number of scientific publications retracted and research misconduct cases revealed in recent years, Chinese biomedical research integrity is questioned. As institutions educating and training future researchers, universities and the guidance they provide are important for the research quality and integrity of the country. Therefore, through a review of the guidance and policy documents on research integrity in Chinese universities, this work aims to investigate how the professional norms are specified in these documents. Methods: After a stratified sampling, 53 universities were selected. Their guidance and policy documents on research integrity were collected via a web search of their official websites. The search was confirmed by these universities. Then the content of all the collected documents were analyzed using inductive content analysis. Results: 118 active university documents were collected and analyzed. Most of the Chinese universities we investigated had their own guidance or policy on research integrity. They listed principles or examples of desired and undesired academic practices, investigation procedures and punishments of academic misconduct, and put forward measures to promote research integrity. Differences on specific practices and principles were observed between university groups and with European university documents. Conclusion: Despite the discrepancy they have, all these documents were designed to promote research integrity and cultivate a good research environment in Chinese biomedical domain. Nevertheless, there is still room for improvement, for example, through more consultation of international guidance.
