New Delhi, July 5 (ANI): A search engine named Renrou, which literally means human flesh, is the new judge and jury of angry netizens as it virtually punishes people with unbecoming behaviour. The search engine involves thousands of individuals, all mobilized to dig out facts and expose the baleful glare of publicity. The Internet and conventional search engines are used for the purpose. In 2001, a netizen posted the photo on Mop of a girl, claiming her to be his girlfriend. However, Renrou helped other web users find out that woman was Microsofts model Chen Ziyao, and her personal information was later used to expose that man. A 41-year-old nurse named Wang Jue was suspended from her job when netizens using Renrou dug out her personal details while probing a video that showed her stabbing a kitten in the eyes with her high heels, and crushing its head. There was observed a peak of Renrou searching when a husband whose wife committed suicide because of his betrayal, a man who disrupted torch relay in Paris, and a girl from northeastern China who dared to criticize those affected by the massive earthquake became targets. Those who mistreated the vulnerable are likely to incur the hatred of netizens, Chinese news agency Xinhua quoted an online freelancer nicknamed Ayawawa, who herself was involved in a search for a disloyal husband, as saying. I just want them to be punished, she said, adding that according to Chinese law, such behaviour, although immoral, invite no legal punishment. When a girl from a college in Chongqing municipality said on the Internet that the May 12 earthquake was interesting, her mother and teacher started to receive cursing and threatening phone calls from angry netizens, forcing the girl to suspend her schooling. The China Youth Daily recently surveyed 2,491 netizens, and found 79.9 per cent of them to believed that Renrou search should be regulated. While 65.5 per cent thought it might become a new way of venting anger and revenge, 64.6 per cent said that it was infringing privacy, and 20.1 per cent feared that they could become a target. Ayawawa also agreed that some targets were just scapegoats for netizens to vent their anger in daily life. The survey also revealed that 24.8 per cent of those polled supported legislation to restrict Renrou searches.

working paper 001 理性利己人之间的社会合作博弈模型 : 市场经济体制的微观经济学理论基础探索 武爱 Aiwu5@sina.com.cn 摘 要 :市场经济体制是以市场自由交易为微观基础的体制,市场交易的机制或原理是实行市场经济体制的一个重要理论依据。本文提出一个不同于 Gintis 的合作博弈模型,这个模型主要是以市场经济的交易均衡理论为基础构建的 。研究初步表明:即使是非血缘关系的理性利己人之间也可以通过市场交易的方式实现利己与利他的有机统一,从理论上解释说明了市场经济体制通过交易能够使交易的双方实现互惠互利、共同进化的原因。可以认为市场交易机制——这种理性利己人之间的合作博弈模型正是促进社会分工形成现代化产业、城市化经济的一个由来,也是人类社会能够区别于其他动物得到持续和谐进化的一个理论原因。 关键词 :理性;利己;利他;交易;分工;合作博弈;模型;社会经济学;演化经济学 Social Cooperation Game Model between Rational Agents: The Basic Exploration on the Mechanism of Market Economy Ai WU Aiwu5@sina.com.cn School of Management,Dalian University of Technology,Dalian 116023, China Abstract : Transactions are the most common phenomenon in market economy. But in theoretical research, modeling a transaction is a complex problem unsolved. In this paper, firstly, natural rationality (A) is defined as nonlinear function of agent’s benefit (B) and cost(C). Secondly, two basic definitions of neutrality value system for market economy are constructed: seller value and buyer value. Thirdly, value equilibrium of a bargaining game is modeled when the seller value is equal to the buyer value, and equilibrium price solution in a transaction is obtained. Finally, the relationship between transaction model and social order is analyzed.

Investigations into the dynamics of mine truck operations, elephant foraging and Hamlet 采矿车运作、大象觅食和《哈姆雷特》的动态 研究 文后附上两位教授的中文简历。 Prof. Dr. Kevin Jan Duffy and Prof. Dr. Pavel Yaroslavovich Tabakov of Durban University of Technology, South Africaare visiting my lab during June 24-26. Prof. Duffy is my postdoctoral supervisor. It was amazing that he gave us a talk about math models on three real world systems. At first I could not understand what are the connections between diamond mine trucks, African elephants and the Sharespearean play Hamlet. The After the talk, I gradually grasp the role of mathematical models, which are the only connections among the above irrelevant phenomena. What interests me most is that Kevin is applying the predator-prey .models to study the tension between rationality and emotionality in Hamlet. 我很高兴的邀请到南非德班理工大学的Duffy、Duffy两位教授访问我的实验室,其中Duffy教授是我的博士后导师。在Duffy教授的报告中,唯一能够把钻石采矿车、非洲象和莎士比亚戏剧《哈姆雷特》联系在一起的是数学模型。我很感兴趣的是他用捕食者-猎物模型来研究《哈姆雷特》中理性和感性之间的tension(张力??) Here's the abstract of the talk 以下是报告的摘要: To understand real world systems it is often useful to use mathematical and computational models. At the Centre for Systems Research we use a number of different techniques to help in understanding a variety of real world questions. In this talk we will discuss three of our existing projects which are very different and hope to show that similar mathematical paradigms are useful in describing these systems. The projects are studies of mine haul truck operations, elephant movement ecology and the Shakespearean play Hamlet. 采用数学和计算模型有助于了解真实世界系统。在系统研究中心( Centre for Systems Research ),我们采用许多不同的技术 来帮助了解各种各样的现实世界问题。在这个报告中,我们将讨论我们现有的三个截然不同的项目,希望阐明相似的数学范式对于描述这些系统是有用的。这些项目包括:采矿车运作、大象运动生态学和莎士比亚戏剧《哈姆雷特》。 中文简历: Kevin Duffy教授、博士 南非Durban University for Technology系统研究中心主任,澳大利亚RMIT University数学与地球空间科学学院兼职教授。1982年南非University of Natal数学和心理学学士,1984年University of Natal荣誉学士,1989年University of Natal机械工程硕士,1995年美国University of Virginia生物物理学博士。曾任University of Virginia生物物理学项目组研究助理,University of Natal数学和应用数学系研究助理。主要研究领域是将计算方法和数学模型应用于现实世界,在数学分析,计算机模拟和元胞自动机方面有所专长。主持或参与的研究项目涉及:与生态系统动态相关的动物运动的计算机模拟和数学分析;植物植食者数学模型;动物种群动态的估测模型;群落指示种分析技术;艾滋病系统动态模型;能源利用效率的计算机技术;社会关系数学模型。International Journal of Computers, Systems and Signals编委。曾为Ecological Applications, Ecological Modelling, Natural Resource Modelling, Journal of Ecological Economics and Statistics等刊物审稿。发表论文生物运动分析、动物生态学、机械工程、数学模型等方向的论文34篇。 主要著作: 1)生物运动分析 方向: 1.Dai X, Shannon G, Slotow R, Page B, Duffy K. 2007.
