Some researchers call it a fully nonlinear Boussinesq model. Different degrees of complexity of G-N theory are distinguished by ＂levels＂ where the higher the level, the more complicated and presumably more accurate the theory is. In the research presented here a comparison was made between two different levels of G-N theory, specifically level II and level III G-N restricted theories. A linear analytical solution for level III G-N restricted theory was given. Waves on a planar beach and shoaling waves were both simulated with these two G-N theories. It was shown for the first time that level III G-N restricted theory can also be used to predict fluid velocity in shallow water. A level III G-N restricted theory is recommended instead of a level II G-N restricted theory when simulating fullv nonlinear shallow water waves.展开更多

From political perspective, this thesis will take the popularity of Yu Hua’s works in US into account to analyze and explore how cultural soft power, has impacts on translation activities, especially translation direction and source text selection.展开更多

Understanding the relational structure of collaborative community policing is necessary to pinpoint the pattern of interactions among key actors involved in community policing and improve the effectiveness of network governance. Based on 234 surveys of citizens of S Community in Beijing from April 2017 to May 2017, this paper empirically examines the characteristics of formal network and informal network of citizen participation in the collaborative community policing. Beijing is widely known for its active involvement of neighborhood volunteers in different types of community policing. We focused on four different types of interpersonal work relationships in this study： workflow, problem solving, mentoring and friendship, among resident committees, neighborhood administrative offices, media, police station, business security personnel, neighborhood volunteers, and security activists. The nature of relationships between individuals in networks can be treated as from instrumental ties to expressive ties. Expressive ties cover relationships that involve the exchange of friendship, trust, and socio-emotional support. We extended this intra-organizational insight into a community policing inter-organizational context. The collaborative network showed the trend of the distributed network. The clustering analysis showed that in the workflow network, we should make thll use of the close interaction between the citizens and activists in the community. Meanwhile, in the problem-solving network, mentoring network and friendship network, interactions between citizens and neighborhood committee are weak.展开更多

Thus, this article aims to propose a study methodology to develop strategies for promoting technological innovation, to answer the research question： What actions to leverage the innovative potential of a region？ Data were collected through qualitative and quantitative approaches. The study was characterized as exploratory, descriptive, and inventory. The study sample was composed of the industrial spectrum of Francisco Beltrao region. Innovation indexes were identified companies operating in areas of greatest economic importance. Representatives of the companies were interviewed for the researcher could analyze their knowledge of the laws that encourage innovation and actions imposed by the interested parties and the municipal government. Interested parties were also interviewed to verify the effectiveness of actions. The main results indicated a low overall rate of innovation of companies in the Francisco Beltrao region. Another point was the very low number of companies they knew about laws and incentives. The higher content of knowledge of these laws and actions of stakeholders were among the companies participating in the single business hub of the city looking for technological innovation. The main conclusions brought proposed strategies to promote technological innovation.展开更多

In this paper, we mainly study the global behaviors of discrete-time epidemic model in heterogenous networks. By theoretical analysis, we show that the model can be characterized by the basic reproduction number R0. When R0 is smaller than unit, the disease-free equilibrium is globally stable, while R0 is larger than unit, the unique positive equilibrium is globally attractive.展开更多
