This paper proposes a feature fusion network model Bert-TextLevelGCN based on BERT pre-training and improved TextGCN. On the one hand, Bert is introduced to obtain the initial vector input of graph neural network containing rich semantic features. On the other hand, the global graph connection window of traditional TextGCN is reduced to the text level, and the message propagation mechanism of global sharing is applied. Finally, the output vector of BERT and TextLevelGCN is fused by interpolation update method, and a more robust mapping of positive and negative sentiment classification of public opinion text of “Tangshan Barbecue Restaurant beating people” is obtained. In the context of the national anti-gang campaign, it is of great significance to accurately and efficiently analyze the emotional characteristics of public opinion in sudden social violence events with bad social impact, which is of great significance to improve the government’s public opinion warning and response ability to public opinion in sudden social security events. .展开更多

Then we present a new identity based signcryption scheme using quadratic residue and pairings over elliptic curves. It combines the functionalities of both public verifiability and forward security at the same time. Under the Bilinear Diffie-Hellman and quadratic residue assumption, we describe the new scheme that is more secure and can be some-what more efficient than Libert and Quisquater’s one.展开更多

The theory of risk society points out that the traditional system of hierarchical management should be transformed into the governance system led by government and participated in by multiple parties to avoid and reduce risk in modern society. In order to achieve modernization of the national governance system and capacity,we have to deal with these two important subjects,that is,what can we learn from the Western risk society theory and how to establish a scientific and efficient public security risk management system based on the characteristics of modern public security risk.展开更多

Nowadays, the human society has evolved to a relatively advanced stage, and along with society progress, complicated social relationship and environment will result in more dangerous elements, thus bringing in more risks. This paper introduces the public security crisis management model based on diversified cooperation in detail from the concept of public security crisis and puts forward safeguard mechanism construction for enhancing the crisis management under diversified cooperation in a brief manner, thus improving the efficiency of crisis management under diversified cooperation.展开更多

Since the 21th century, all walks of life have paid more attention to the public security administration in China, along with the deepened implementation of the reform and opening-up policy and the rapid development of economic construction and the effects from the outbreak of the SARS crisis and the frequent occurrence of many coal mine security accidents, etc. In this process, the non-traditional security issues and man-made crisis are gradually becoming the main threats currently to the public security of China, because the conflicts of interest and the social contradictions overlap and the social crisis such as cadres-masses and police-masses conflicts is being aggravated. At present, the Ministry of Public Security of China is pushing forward a community policing reform and great numbers of community polices in community policing administration will directly confront with the challenges of the public security administration complexity, and therefore, the promotion of community policing urgently needs the innovation of administration concept.展开更多

Then, the paper puts forward some designs on structure of the Chinese urban public security system structure. This paper is of the opinion that at present the management of urban public security concerning unexpected incidents should be strengthened. The effective way is to set up the sound urban public security system, urban public security mechanism and related laws and regulations.展开更多

We determine the level of investment in information security and attacking intensity when agents react in a non-coordinated manner and compare them to the case of the system’s coordinated response undertaken under the guidance of a steward. We show that only in the most well-designed institutional set-up the presence of the well-informed steward provides for an increase of the system’s resilience to attacks. In the case in which both the information available to the steward and its policy instruments are curtailed, coordinated policy responses yield no additional benefits to individual agents and in some case they actually compared unfavourably to atomistic responses. The system’s sustainability does improve in the presence of a steward, which deters attackers and reduces the numbers and intensity of attacks. In most cases, the resulting investment expenditure undertaken by the agents in the ecosystem exceeds its Pareto efficient magnitude.展开更多
