This study aims to promote the safe and healthy development of reading apps, and provide better reading services. [Method/Process] This paper selected the top 10 reading apps as the survey objects, and analyzes the user privacy policies from the aspects of the presentation of privacy policies, the collection of user personal information, the storage of user personal information, the sharing of user personal information, and the service provision for teenagers. And it also analyzes the reading apps' main difficulties in user privacy protection. [Results/Conclusions] Since the implementation of "Regulations on Ecological Governance of Network Information Content" since March 1, 2020, many apps have updated their privacy policies, and the presentation of privacy policies for reading apps has become clearer. The privacy policies of reading apps clearly stipulate that personal information collected and generated in the operation within the territory of the People's Republic of China is stored in China. At the same time, this paper puts forward some thoughts on improving the privacy policy of reading app users, mainly including further clarifying the boundary of user information collection, improving the information sharing specification, and refining the privacy protection policy of teenagers.

The purpose is to provide recommendations and strategies for management departments to formulate policies to reduce academic misconduct. [Method/Process] We obtained cases of revoked academic degree through media news, and retrieved various databases and online reading sharing platforms to find the residual situation of the papers. We also analyzed the papers' academic impact by bibliometrics and altmetrics measurement. [Results/Conclusions] The results show that 75% retracted dissertations and theses were still in databases and online reading and sharing platforms, and 36% of them were retracted. Bibliometrics analysis found that 58% retracted papers were cited, and one-third of which occurred after the retraction. Altmetrics analysis found that 84% papers were uploaded, collected, shared, commented, and reposted. And 24% of them were uploaded after the retraction. Finally, we put forward the governance strategies from the perspectives of research integrity education and academic misconduct punishment.
