On Quantum Team Games

Recently Liu and Simaan (2004) convex static multi-team classical games have been introduced. Here they are generalized to both nonconvex, dynamic and quantum games. Puu's incomplete information dynamical systems are modified and applied to Cournot team game. The replicator dynamics of the quantum prisoner's dilemma game is also studied.

Dynamic models of segregation†

Some segregation results from the practices of organizations, some from specialized communication systems, some from correlation with a variable that is non‐random; and some results from the interplay of individual choices. This is an abstract study of the interactive dynamics of discriminatory individual choices. One model is a simulation in which individual members of two recognizable groups distribute themselves in neighborhoods defined by reference to their own locations. A second model is analytic and deals with compartmented space. A final section applies the analytics to ‘neighborhood tipping.’ The systemic effects are found to be overwhelming: there is no simple correspondence of individual incentive to collective results. Exaggerated separation and patterning result from the dynamics of movement. Inferences about individual motives can usually not be drawn from aggregate patterns. Some unexpected phenomena, like density and vacancy, are generated. A general theory of ‘tipping’ begins to emerge.     

论《赵氏孤儿》的悲剧快感

《赵氏孤儿》是著名的古典悲剧,给人带来悲的世界,但这种悲不是绝望的悲,是一种给人奋发向上的悲。悲剧中既有痛感的体现,也有一种快感在其中。讨论《赵氏孤儿》戏剧的悲剧快感,主要从韩厥两难处境、屠岸贾的过场作用对《赵氏孤儿》加以审美的分析和提炼,从艺术自身的角度看待《赵氏孤儿》方能体会到它长久不衰的魅力。     

西藏农村人力资本投资困境分析

农村人口综合素质整体不高,日益成为西藏农村反贫困和可持续发展的重要制约因素之一,加大人力资本投资日益迫切.文章提出没有基于本地化的农村办学思路,师资队伍整体落后与教育质量不高长期并存,教育投资观念偏差根深蒂固,基层卫生服务能力薄弱及健康知识普及严重不足等是当前西藏农村人力资本投资存在的诸多困境,并指出尽快优化教育发展结构、突出师资队伍建设、加强成人培训力度、关注妇女儿童健康是提高农村人口发展能力的重要途径.     

Nationalism Reflected in Barometer Rising

Hugh MacLennan is a famous Canadian novelist and essayist. In his long literary career, he wrote a great number of works and gained many literary honors. But above all, he is a writer, focusing on national issues of Canada, which is well demonstrated by his first novel-Barometer Rising, in which nationalism abounds. This paper covers three parts. Chapter one is mainly about Hugh MacLennan, his first work Barometer RAsing as well as the introduction to nationalism and MacLennan＇s contribution in fiction in this respect. Chapter two focuses on nationalism in his first novel. The last chapter is the conclusion part in which we know that well awakened, the Canadians are striving to pursue their real independence and stares on the international stage.     

Spatial prisoner’s dilemma games with increasing size of the interaction neighborhood on regular lattices

We studied the evolution of cooperation in the prisoner’s dilemma game on a square lattice where the size of the interaction neighborhood is considered. Firstly, the effects of noise and the cost-to-benefit ratio on the maintenance of cooperation were investigated. The results indicate that the cooperation frequency depends on the noise and cost-to-benefit ratio: cooperation reaches a climax as noise increases, but it monotonously decreases and even vanishes with the ratio increasing. Furthermore, we investigated how the size of the interaction neighborhood affects the emergence of cooperation in detail. Our study demonstrates that cooperation is remarkably enhanced by an increase in the size of the interaction neighborhood. However, cooperation died out when the size of the interaction neighborhood became too large since the system was similar to the mean-field system. On this basis, a cluster-forming mechanism acting among cooperators was also explored, and it showed that the moderate range of the neighborhood size is beneficial for forming larger cooperative clusters. Finally, large-scale Monte Carlo simulations were carried out to visualize and interpret these phenomena explicitly.
