Human Culture and Science: Equality and Inequality as Foundations of Scientific Thought

We argue that the concepts of `human equality' and `inequality' play an important role in the structure of science and philosophy. When the value of `human inequality' predominates, scientific categories are formed in accordance with the principle of `hierarchical differentiation' and concepts remain closely tied to the objects they are referring to. Following Mirowski we define this as the `anthropometric stage' of human thought and development. Contrary, Mirowski's `syndetic stage' refers to societies where the value of `human equality' prevails. Here concepts appear that are universally applicable. However, because of their conventional nature these concepts cannot be `grasped' any longer by human intuition. Between the `anthropometric' and `syndetic' stages, a `lineamentric stage' appears, a period of transition from `human equality' to `human inequality'. Being both a bridge and gap between the two other stages, the `lineamentric' stage contains many contradictions between an `abstract attitude' and `concrete categories'. In this paper we examine the anthropometric, lineamentric and syndetic stages and discuss several examples taken from philosophy, logic, mathematics and physics.

全面建设小康社会时期我国竞技体育发展的战略任务

运用文献资料调研、逻辑分析等方法,分析了在全面建设小康社会的进程中我国竞技体育存在的问题及其所面临的机遇,再次基础上总结出这一新时期我国竞技体育发展的战略任务。结果表明:目前,我国竞技体育还没有完全形成与当前市场经济相适应的管理、训练、竞赛及保障体制,应抓住全面建设小康社会这一战略机遇期,进一步探索"体教结合"的培养模式,加强推进项目实体化改革的力度,加快体育产业发展的步伐,提升竞技体育的国际话语权,最终推动体育强国目标的实现。     

基于人工股票市场的财富分布及演化研究

采用多主体建模的方法构建了一个具有真实股票市场特征的人工股票市场,通过对3类异质投资者信息资源禀赋及交易行为的刻画,展现了市场财富的幂律分布特征,并发现财富分布的基尼系数随着机构投资者初始市场占比的增加而减小。这意味着市场财富会向信息占优的机构投资者手中聚集,但整体财富分布的非均等程度会随着更多机构投资者的加入而减弱。基于以上结论,从优化资源配置公平的角度对中国股票市场提出了相关建议。

一种改进的基于地理位置的无线Mesh网络路由协议

提出了一种基于地理位置的干扰感知路由协议IAPR(Interference Aware Progress Routing),该算法通过感知无线信道的干扰特征对贪婪转发和空洞绕行过程进行改进。在贪婪转发模式下,通过权衡转发距离与链路质量以及信道接入难度实现对下一跳节点的选择,使得分组在保证转发距离的基础上选择更有利于传输的链路;当分组到达了局部最小点时,启用基于竞争的机会式转发。在竞争因素中加入了分组由空洞绕行模式回到贪婪转发模式可能性的因素,在空洞边缘处帮助分组转回到贪婪模式的邻居节点将在竞争中获得最高的优先级,继而获得首先转发的机会。NS2仿真实验结果表明,IAPR路由算法能够更好的实现分组转发,提高分组的传输效率。

Residual income,non‐earnings information,and information content

We extend Ohlson's (1995) model and examine the relationship between returns and residual income that incorporate analysts' earnings forecasts and other non‐earnings information variables in the balance sheet, namely default probability and agency cost of a debt covenant contract. We further divide the sample based on bankruptcy (agency) costs, earnings components and growth opportunities of a firm to explore how these factors affect the returns–residual income link. We find that the relative predictive ability for contemporaneous stock price by considering other earnings and non‐earnings information is better than that of models without non‐earnings information. If the bankruptcy (agency) cost of a firm is higher, its information role in the firm's equity valuation becomes more important and the accuracy of price prediction is therefore higher. As for non‐earnings information, if bankruptcy (agency) cost is lower, the information role becomes more relevant, and the earnings response coefficient is hence higher. Moreover, the decomposition of unexpected residual income into permanent and transitory components induces more information than that of the unexpected residual income alone. The permanent component has a larger impact than the transitory component in explaining abnormal returns. The market and industry properties and growth opportunity also have incremental explanatory power in valuation. Copyright © 2008 John Wiley & Sons, Ltd.
