Aiming at the problem on cooperative air-defense of surface warship formation, this paper maps the cooperative airdefense system of systems (SoS) for surface warship formation (CASoSSWF) to the biological immune system (BIS) according to the similarity of the defense mechanism and characteristics between the CASoSSWF and the BIS, and then designs the models of components and the architecture for a monitoring agent, a regulating agent, a killer agent, a pre-warning agent and a communicating agent by making use of the theories and methods of the artificial immune system, the multi-agent system (MAS), the vaccine and the danger theory (DT). Moreover a new immune multi-agent model using vaccine based on DT (IMMUVBDT) for the cooperative air-defense SoS is advanced. The immune response and immune mechanism of the CASoSSWF are analyzed. The model has a capability of memory, evolution, commendable dynamic environment adaptability and self-learning, and embodies adequately the cooperative air-defense mechanism for the CASoSSWF. Therefore it shows a novel idea for the CASoSSWF which can provide conception models for a surface warship formation operation simulation system. 展开更多

The close-in weapon system(CIWS)is a combat system that faces a complex environment full of dynamic and unknown challenges,whose construction and planning require a systematic design method.Multiliving agent(MLA)theory is a methodology for the combat system design,which uses the livelihood degree to evaluate the multi-dimensional long-term operational effectiveness of the system;whereas,there is still no uniform quantization framework for the livelihood degree,and the adjustment methods of livelihood degree need to be further improved.In this paper,we propose the uniform quantization framework for the livelihood degree and detailed discuss the methods of livelihood adjustment.Based on the MLA theory,the multi-dimensional operational effectiveness of the missile-gun integrated weapon system(MGIWS)is analyzed,and the long-term combat effectiveness against the saturation attack is assessed.Furthermore,the planning problem of the equipment deployment and configuration is investigated.Two objectives,including the overall livelihood degree and cost-effectiveness(CE),are proposed,and the optimization method based on genetic algorithm(GA)is studied for the planning problem. 展开更多

Objective: To investigate the biological basis of qi, blood and vessel in immune thrombocytopenia(ITP) patients with syndrome of qi failing to govern blood(SQFGB) based on traditional Chinese medicine.Methods: A total of 52 ITP patients with SQFCB were enrolled and divided into bleeding group(38 cases) and non-bleeding group(14 cases).Bleeding group was further divided into mild qi deficiency group(25 cases) and moderate/severe qi deficiency group(13 cases) based on Chinese Medicine syndrome score.20 healthy volunteer were recruited as control group.The count of platelet(PLT) was taken as the blood related indicator.The expressions of cytokines including IL-1β, IL-17 A, TNF-α, CD40 L, and TGF-β, detected by Aim Plex Multiple Immunoassays for Flow, were taken as the qi related indicators.The expressions of VEGF-A, detected by Aim Plex Multiple Immunoassays for Flow and NO, NOS, and ET-1 detected by ELISA, were taken as the vessel related indicators.Results: As compared to the control group, the count of PLT, taken as the blood related indicator, was significantly lower in ITP group patients with SQFCB(P<0.05).The expression levels of IL-17 A and TNF-α, taken as the qi related indicators, were significantly higher, while those of CD40 L, IL-1β, and TGF-β, also taken as the qi related indicators, were significantly lower in ITP patients with SQFCB, respectively(P<0.05).The expression levels of NO and ET-1, taken as the vessel related indicators, were significantly higher, while the expression levels of NOS and VEGF-A also taken as the vessel related indicators, were significantly lower in ITP patients with SQFCB, respectively(P<0.05).The count of PLT, taken as the blood related indicator, was significantly lower in moderate/severe group than those in mild group(P<0.05).The expression levels of CD40 L and TGF-β, taken as the qi related indicators, were also significantly lower in moderate/severe group than those in mild group, respectively(P<0.05).Conclusion: The count of PLT might be the biological basis of blood.The expressions of NO, NOS, ET-1 and VEGF-A might be the biological basis of vessel.The expressions of IL-1β, IL-17 A, TNF-α, TGF-β, and CD40 L may be the biological basis of qi.The expressions of CD40 L and TGF-β could reflect the degree of qi deficiency in ITP patients based on the theory of qi and blood. 展开更多

In order to find out reasons for local government illegally occupying cultivated land and reduce such acts to ensure China's grain security,this paper made an analysis through building the single person game model for local government's legal or illegal occupation of cultivation land.It reached the conclusion that the benefit obtained by local government from illegal occupation of cultivated land is far greater than cost and punishment of such illegal acts.Illegal act is an optimal choice of local government to maximize its benefits,which is also the major reason for its illegal occupation of cultivated land.Thus,to reduce these illegal acts of local government,it should reduce benefits of local government obtained from illegal occupation of cultivated land,and increase costs for illegal occupation of cultivated land. 展开更多

With respect to different risk preference of an agent in a supply chain, linear-contract models are designed according to the principal-agent theory. The study shows that the risk preference of an agent directly correlates with the incentive compensation coefficient of principal, order quantity of principal and production capability level of the agent. The principal should offer an appropriate incentive contract according to the risk preference of the agent, or choose an agent holding a different risk preference to establish the supply chain. 展开更多

The reorganization of the global production network and the increased mobility of urban-rural elements have accelerated the differentiation of rural spaces,resulting in a trend towards specialization in rural areas.This paper focuses on the concept of specialization,and takes a renowned bonsai specialized village in Guangzhou City,China as a typical case to explore its transformation and development process,action logic and coupling mechanism with the social governance.The results show that:1)the development of rural specialization in Ruiling Village is shaped by several key actors,such as local governments,grassroots organizations,villagers,social organizations,policies,markets and infrastructure.The transfer of these key actors and the reconstruction of actor-networks in different stages have an important influence on the transformation and realization of rural development goals.2)Through subjects-driven,organization management and resource connection,social governance supports the specialization of rural industrial organization,operation,technology and mode.The governance structure shifts from decentralization to networking,refinement and integration.A coupling community of social governance and specialization is created by the social governance system of‘local government-grassroots organizationseconomic cooperatives-villagers’,which links industries,industrial chains and cooperatives.3)Social governance integrates into the value chain extension process of rural specialized development with a central,multi-level organizational structure.It promotes the construction of the whole value chain through organizational planning,resource integration and image shaping,thus realizing the value,branding and organization of the industry,as well as the integration of rural sustainable development and governance mechanism.Social governance has a profound impact on the development of rural specialization in terms of subject,structure and mode,and participates in the construction of the whole value chain of rural areas.This paper provides a new perspective for understanding the coupling effect of social governance in the rural development transformation,and promotes the rural sustainable development and governance. 展开更多

The telecommunications industry has been undergoing tremendous technological changes, and owning to continuous technological advancement, it has maintained sustained prosperity and development. In this paper, the interplay between technology, market and government in telecommunications is discussed briefly, and then we introduce technology and government into the traditional SCP(Structure – Conduct – Performance) paradigm to develop an industry analysis framework called TGM(SCP)(Technology – Government – Market(Structure – Conduct – Performance)). Based on this framework, we present the spiral coevolution model which elaborates on the interaction mechanism of technological innovation with government regulation and market dynamics from the perspective of industry evolution. Our study indicates that the development of the telecommunications industry is the result of the coevolution of technology, government regulation and market forces, and among the three actors, technology is the fundamental driving force. Relative to the "invisible hand"(market) and "visible hand"(government), we conceptualize technology as the "third hand", which fundamentally drives the development of telecommunications industry in coordination with the other two hands. We also provide several policy implications regarding these findings. 展开更多

With the new round of scientific and technological revolution and industrial transformation,China has posited the direction of“new infrastructure”in 2020.As one of the seven major industries of the“new infrastructure”,the charging infrastructure(CI)industry not only supports the upgrade of the new energy vehicle industry but also provides developing platforms for emerging industries,such as wireless charging,energy storage,smart microgrid,and new energy consumption.Therefore,the government’s supporting role is crucial for the CI industry.To effectively explore the effectiveness of government’s subsidy policy in the CI industry and promote its healthy development,we employed a game model and discussed the government's evolution process of different game strategies between CI and battery-swapping station(BSS)operators in this study.First,China's government subsidies for the electric vehicle(EV)industry were classified into CIs and BSSs.The subsidies obtained by the CI operators were operating subsidies,whereas those obtained by BSSs were investment subsidies.Second,a game model was constructed,involving the government,operators,and users.The model used backward induction to seek the refined Nash equilibrium solution for CIs and BSS operators.The Nash equilibrium solution indicated that the optimal investment amount and BSS quantity of the operator were positively correlated with the government subsidy intensity.When the profitability of the operators increased and the amount of the subsidies increased,consumers’willingness to use EVs increased and the policy effects were closely related to the benefits of government management.The decisions made by either the users or the operators were inversely related to the operators’management efficiency.Besides,the subsidy policy was affected by the government management.Therefore,in the implementation stage of the government’s future subsidy policies,the government needs to innovate and improve management effectiveness.The government could use subsidy policies as a driving force for developing the CI industry to build a comprehensive ecosystem of the industry,which is also the next key point for the government to promote the development of the CI industry in the future. 展开更多

In the global environment of pursuing resource regeneration and green environmental protection, more and more wasted clothing need to be solved. In order to make full use of the wasted clothing and save land and soil resources, an idea of wasted clothing's recycling and remanufacturing is put forward. In the new idea a pricing game model is established basing on Stacklberg differential game theory between traditional and remanufactured clothing. In this model, the differences in consumers' willingness to pay and the government's subsidies are considered. Government's optimal subsidy are obtained which ensure not only the interests of manufacturers but also environmental reputation and maximum social benefits. The study is helpful to push the wasted clothing's recycling and remanufacturing plan. It makes some index more precise quantification as government's subsidy, manufacturers and the social benefits. Government and manufactures can make the detailed cooperation plan reference to it. 展开更多

Maltese Local Councils are required to prepare financial reports compliant with International Financial Reporting Standards (IFRS). Through documentary research, this study examined the suitability of this requirement and implications for institutional relationships. This study showed that IFRS statements are problematic to produce and interpret at the local level of government, and that, on their own, they are undermining the control needs of the Central Government. This study highlighted the important role of financial reporting for accountability by showing that the use of financial reporting systems that do not fit the reporting entity may actually lead to avoidance of accountability by mystifying reality. 展开更多

The rising of the great power shock the rest countries. More and more people want to know what is happening in this country and what effect it will bring to the world. At the same time, Chinese people have gradually realized the importance of exchanging information with other countries. Under this motivation, the translation of Chinese materials into English becomes necessary and essential. It is an effective way to present China comprehensively. Among all these materials, Government Work Report is one of the most remarkable ones. The translation of it plays a key role to present the image of China to the world. But, compared with State of the Union address, the translation of Government Work Report contains some problems from the perspective of foreignization and domestication theory. This essay will discuss the differences between these two texts at the lexical, syntactic, and discourse level from the angle of foreignization and domestication theory, and give some suggestions to the translation of Government Work Report. 展开更多

Palmer&Harvey(P&H)is a recent example of a UK corporate failure which raises questions about current corporate governance practice,the quality and integrity of audit reporting,and the“sugar coating”of Annual Reports.P&H is but one example of UK firms currently struggling to survive,or failing.The paper presents some details about the P&H case,and then considers questions about corporate governance practice,and whether it is designed to truly safeguard the interests of stakeholders;it raises questions about conventional audit reporting,and whether it is too limited in its analysis and reporting.The paper recommends a strengthening of corporate governance guidelines and practice within the terms of the current Financial Reporting Council(FRC)review,and a wider adoption of forensic accounting practice and reporting,in part taking account of the impact of behavioural factors in management practice.A wider study is proposed to take this analysis and discussion further. 展开更多

The theory of proximization is an effective discourse strategy to study the speaker’s ability to achieve his own legitimacy or reinforce the other’s illegitimacy,and its superiority can be maximized by means of quantitative and comparative analysis.In this study,we collected reports on Trump’s and Biden’s policies on China to build two small corpora,with a total of 11,030 words in the Trump corpus and 17,566 words in the Biden corpus.The critical discourse analysis is combined with proximization theory.With the help of BFSU Qualitative Coder 1.2,Antconc 3.5.7,and Log-Likelihood and Chi-Square Calculator 1.0,a critical cognitive score of the relevant discourse was conducted from the perspective of proximization theory.It has been found that:(1)Both Trump and Biden administrations resort to a large number of spatial proximization strategies to build ODCs converging to IDCs with China as the ODC,posing a threat to internal physical IDCs;(2)in the use of temporal proximization strategy,both administrations use primarily modal verbs and various entities to construct ODCs that extend indefinitely into the present and future,emphasizing the urgency and the threat of the effect and reinforcing the legitimacy of their actions;(3)in terms of axiological proximization strategy,the two administrations differ greatly from each other,indicating that there are still discursive biases. 展开更多

To investigate the leader-following formation control, in this paper we present the design problem of control protocols and distributed observers under which the agents can achieve and maintain the desired formation from any initial states, while the velocity converges to that of the virtual leader whose velocity cannot be measured by agents in real time. The two cases of switching topologies without communication delay and fixed topology with time-varying communication delay are both considered for multi-agent networks. By using the Lyapunov stability theory, the issue of stability is analysed for multi-agent systems with switching topologies. Then, by considering the time-varying communication delay, the sufficient condition is proposed for the multi-agent systems with fixed topology. Finally, two numerical examples are given to illustrate the effectiveness of the proposed leader-following formation control protocols. 展开更多
