The competition and equilibrium analysis of LCD TV and PDP TV

This study has investigated the dynamic competitive relationship between PDP TVs and LCD TVs by means of their quarterly shipments. The renowned Lotka-Volterra competition diffusion model has been adopted to conduct the empirical analysis with the Lyapunov function to carry out equilibrium and stability analysis, and estimate the domain of attraction which describes the trend and phenomenon of TV shipments. The results illustrate that there is good fitting performance while adopting this model. The competitive relationship can be viewed from the perspective that the LCD TV is the prey while the PDP TV is the predator. The possibility, nevertheless, for dropping the price of LCD TVs is an advantage of the attractiveness of the product which can be noted in higher growth rate than PDP TVs. With respect to the equilibrium stability analysis and estimated domain of attraction, 40- to 49-inch PDP TVs will not disappear from the market, but will generate a stable equilibrium with LCD TVs and sales volume presents simultaneous increase or decrease. In the supply and demand analysis, LCD TVs present a surplus of supply from 2008; therefore, how to conduct appropriate inventory management will be an emerging issue.     

纠正市场失灵的对策分析

改革开放以来,随着市场经济的发展,我国出现了市场失灵的现象。真正做到有效地弥补市场失灵,还要靠政府通过发挥经济职能来做到。针对市场失灵表现的五个方面:垄断性失灵,外部效应,公共产品的提供,失业、通货膨胀和经济失衡以及收入分配问题,政府应该提高效率,有效治理失业、通胀和经济失衡,增进公平的职能调节收入分配,主要是运用收入再分配来弥补市场失灵。     

Effects of mentoring functions on receivers' organizational citizenship behavior in a Chinese context: A two-study investigation

This research examines the relationship between mentoring functions received by employees and their organizational citizenship behavior (OCB), and the moderating effects of perceived quality relationships with mentoring function providers in China. Results of Study 1 from a sample of 385 supervisor-subordinate dyads reveal that role modeling received by protégés positively relates to their OCB, and perceived mentoring relationship quality moderates the association between career support received and protégés' OCB. Moreover, nonprotégés and protégés who receive high levels of overall mentoring functions perform more OCB than protégés who receive low levels of mentoring functions. Results of Study 2 from 258 supervisor-subordinate dyads show that role modeling received by subordinates positively relates to their OCB directed at individuals (OCBI) and at the organization (OCBO) while career support received positively relates to OCBO. Additionally, leader-member exchange moderates the linkages of role modeling with OCBI and OCBO.     

我国政府转型与经济增长的实证分析

以1978—2008年的统计数据为依据,从我国财政支出及其结构的角度出发,描述我国改革开放以来政府职能的转变。对许多学者所认为的投资对经济增长的拉动作用会逐渐减弱以及城乡收入差距拉大的解决方案是增加财政中的支农支出进行实证分析,得出与一般理论相违背的结论,在此基础上提出我国政府职能转变应从转变经济增长方式,实现社会公平、公正方面入手。     

中国企业内部资本市场的功能、陷阱及其法律规制

中国现阶段内部资本市场具有优化融资渠道、催化产业整合以及改进公司治理的功能,但由于信息不对称及代理问题而存在利益侵占、过度投资、风险扩散以及低效率补贴等诸多潜在陷阱。完善的法律规制体系将有助于减少机会主义的内部资本市场运作所带来的负面效应。

The Benefit Function Approach to Modeling Price-Dependent Demand Systems: An Application of Duality Theory

In this article, we advocate more extensive use of the benefit function in specifying price-dependent or inverse demand models. We demonstrate how duality theory may be used to establish the interrelationships between the Marshallian (or Hicksian) inverse demands and Luenberger's adjusted price functions, allowing estimable inverse demands to be derived directly from a benefit function. We estimate two systems of inverse demands for Japanese quarterly fish consumption. Results indicate that the procedures and methods employed here appear promising, and may prove beneficial for quantity and welfare analysis when modeling systems of inverse demand functions.     

Turbo码的Taylor-Log_MAP译码算法

以Turbo码基本理论和算法为基础,依据无线信息传输的实际要求和Taylor级数的基 本原理,提出了一种Turbo码的Taylor-Log-MAP高效译码算法。该算法对基本的Log-MAP 算法中K运算利用Taylor级数进行展开,针对实际的信道需求对展开式进行截断,实现了Tur bo码 的最佳译码。与传统的对数域最大后验概率译码算法相比,该算法基本保持了优良的译码 性能,同时避免了复杂的对数运算,减小了运算量。仿真结果表明,与现 有的RS码性能相比,使用Turbo码可以获取5 dB的信噪比增益。
