Perceived organizational diversity and employee behavior

While the impact of organizational diversity on employee work outcomes has received significant research attention, there is a dearth of literature in hospitality settings, particularly in Eastern cultures. Integrating the Social Identity Theory and diversity literature, this study, using data collected from 22 hotels in Taiwan, examined the relationship of perceived organizational diversity with Job Performance (JP), Organizational Citizenship Behaviors (OCB) and Turnover Intention. The results indicated that the level of diversity perceived by hotel employees, significantly influenced employee JP and OCB. Ethnicity status also moderated the relationship between the perception of diversity levels and employee turnover intention. Specifically, a negative relationship between perceived diversity and turnover intention was observed among indigenous employees while a positive relationship was observed among non-indigenous employees.

保密通信中的分形调制技术

分形调制在保密通信中具有广阔的应用前景。介绍了分形调制的原理,讨论了其在多速率分集、抗1/f噪声、抗频率选择性衰落、适用于信道条件复杂的MIMO通信系统等方面的特点。由于作为密钥的小波基任意多,且可根据信道情况在不同的小波基之间跳变,故分形调制具有极强的保密性和抗破译能力。     

几种发射分集OFDM系统信道估计方法性能评估

给出了3种基于发射分集的OFDM系统信道估计方法,分别从训练序列对算法的影响、估计准确度、算法复杂度和算法适用性等方面对各自性能作了分析比较,并进行了仿真.分析比较和仿真结果表明,训练序列对3种算法的影响很大,通过训练序列的正交化设计,LS和EM算法可以得到很大程度的简化;EM算法与LS算法估计精度相当,信噪比较大时,多项式模型算法估计精度要远远高于LS和EM算法;总体上来说,多项式模型算法复杂度最高,EM算法复杂度最低.     

The social value of income information in a model with market power and endogenous variety

The present paper analyzes the value of public information in a general equilibrium economy with imperfect competition. The welfare effects of an improved information system for perfectly competitive economies have been extensively investigated in the published literature. Schlee (2001) shows that the value of information is always negative in exchange economies if an efficient risk sharing mechanism exists. In contrast, in economies with production, better information reduces welfare provided consumers are sufficiently risk-averse ( Eckwert and Zilcha 2000, 2003 ). In the present paper it will be shown that this result is robust if the production sector exhibits monopolistic competition in the Chamberlinian sense. Even so, the inefficiency of equilibria adds further potential for positive welfare effects of improved information. A model is presented where the degree of market imperfection is positively linked to the value of information. If the markup on competitive prices is sufficiently high, the value of information is positive; that is, better information increases economic welfare.     

Norms and Rationality in the Evolution of Economic Systems: A View from Asian Villages

The evolution of economic systems is viewed as a process in which various informal arrangements are experimented with for improving efficiency under changed economic environments, some of which may survive and become established as new social norms. The process is illustrated by a micro case study of Philippine villages. It reveals the ability of peasants subsisting on small farms to resolve a major disequilibrium between labour's marginal productivity and the wage rate resulting from the intro duction of modern rice technology, by creating, on the basis of their traditional experience, an appropriate institution consistent with their cultural norm. Concurrently, large estate farms were seen to arrive at an inferior outcome because of their inability to utilize the peasant community's norm, thereby demonstrating the existence of multiple equilibria

TD-SCDMA系统中一种软件集成智能天线算法

给出了一种采用信干噪比准则的、集成了预多波束天线与LMS自适应天线的软件天线方案,该方案采用开关合并方法,把软件天线输出接到最大输出信噪比的算法输出,实现算法分集.在TD-SCDMA动态模型上对提出的方法进行了仿真,结果表明,采用集成软件天线方案的误码率性能要优于单纯的预多波束天线或LMS自适应智能天线.仿真过程考虑了用户来波方向和用户到基站距离的动态变化,以及功率控制算法和系统同步过程的影响.
