Video surveillance plays a vital role in maintaining the social security although, until now, large uncertainty still exists in danger understanding and recognition, which can be partly attributed to intractable environment changes in the backgrounds. This article presents a brain-inspired computing of attention value of surrounding environment changes with a processes-based cognition model by introducing a ratio valueλof EC-implications within considered periods. Theoretical models for computation of warning level of EC-implications to the universal video recognition efficiency are further established. Imbedding proposed models into the online algorithms is suggested as a future research priority towards precision security for critical applications and, furthermore, schemes for a practical implementation of such integration are also preliminarily discussed.

Xi Chen explores the question of why there has been a dramatic rise in and routinization of social protests in China since the early 1990s. Drawing on case studies, in-depth interviews and a unique data set of about 1,000 government records of collective petitions, this book examines how the political structure in Reform China has encouraged Chinese farmers, workers, pensioners, disabled people and demobilized soldiers to pursue their interests and claim their rights by staging collective protests. Chen suggests that routinized contentious bargaining between the government and ordinary people has remedied the weaknesses of the Chinese political system and contributed to the regime's resilience. Social Protest and Contentious Authoritarianism in China challenges the conventional wisdom that authoritarian regimes always repress popular collective protest and that popular collective action tends to destabilize authoritarian regimes.

Information-sharing behavior is affected by identity recognition perception. The current study aims to delve into the impact of familiarity and anonymity on information-sharing behavior, and the mediating role of intrinsic motivations on WeChat Moments. We hypothesized a mediator role of intrinsic motivations in the relationship between an individual’s perceptions and information sharing. Based on the self-determination theory, a model was created and tested using a sample of 531 frequent users. In this study, these users were asked to use WeChat Moments, the most popular mobile private social networking site in China. The results demonstrate the significance of familiarity and identifiability in an interpersonal relationship, when using social networking sites. Moreover, the influence of perceived anonymity on information-sharing behavior, which is entirely mediated by intrinsic motivation has been validated from an empirical perspective. Our findings extend previous studies by showing the totally mediated effect of perceived anonymity on information-sharing behavior on WeChat Moments and the influential mechanism of intrinsic motivation. The results will inform researchers about the importance of incorporating the interpersonal structural features and intrinsic motivation of social networking sites into future studies on online information-sharing behavior. Important ways to promote attention and share information involve building a familiar relationship with communities and equipping oneself with off-line relations. Final indications for future developments are provided, with a special emphasis on the development of these findings in various social networking sites contexts.
