Background: In recent years, online trolling has garnered significant attention due to its detrimental effects on mental health and social well-being. The current study examined the influence of peer victimization on adolescent online trolling behavior, proposing that hostile attribution bias mediated this relationship and that trait mindfulness moderated both the direct and indirect effects. Methods: A total of 833 Chinese adolescents completed the measurements of peer victimization, hostile attribution bias, trait mindfulness, and online trolling. Moderated mediation analysis was performed to examine the relationships between these variables. Results: After controlling for gender and residential address, the study found a significant positive correlation between peer victimization and online trolling, with hostile attribution bias serving as a mediator. In addition, trait mindfulness moderated the direct relationship between peer victimization and online trolling. Specifically, the effect of peer victimization on online trolling was attenuated when adolescents had high levels of trait mindfulness. The results of the study emphasized the joint role of peer and personal factors in adolescents’ online trolling behavior and provide certain strategies for intervening in adolescents’ online trolling behavior. Conclusion: The results of the study suggest that strategies focusing on peer support and mindfulness training can have a positive impact on reducing online trolling behavior, promoting adolescents’ mental health, and their long-term development. © 2024 The Authors.

This article analyses Chinese traditional evidence theories that have evolved over a long period of time, to explore which theory, between objectivity and relevancy, best represents the basic attribute and logical thread of evidence. These theories are considered in the context of issues arising in evidential adjudication, including： the ＂Mirror of Evidence,＂ truth, the probability of proof standard, the choice between a notion of pursuing 100-percent certainty in adjudication and that wrongful acquittals are better than wrongful convictions, and the statutory proof doctrine comparedwith the system of free proof. Finally, the article presents the framework of and methods for drafting provisions of procedural evidence of the People＇s Court.

In recent decades, log system management has been widely studied fordata security management. System abnormalities or illegal operations can befound in time by analyzing the log and provide evidence for intrusions. In orderto ensure the integrity of the log in the current system, many researchers havedesigned it based on blockchain. However, the emerging blockchain is facing significant security challenges with the increment of quantum computers. An attackerequipped with a quantum computer can extract the user's private key from thepublic key to generate a forged signature, destroy the structure of the blockchain,and threaten the security of the log system. Thus, blind signature on the lattice inpost-quantum blockchain brings new security features for log systems. In ourpaper, to address these, firstly, we propose a novel log system based on post-quantum blockchain that can resist quantum computing attacks. Secondly, we utilize apost-quantum blind signature on the lattice to ensure both security and blindnessof log system, which makes the privacy of log information to a large ***, we enhance the security level of lattice-based blind signature under therandom oracle model, and the signature size grows slowly compared with *** also implement our protocol and conduct an extensive analysis to prove theideas. The results show that our scheme signature size edges up subtly comparedwith others with the improvement of security level.
