A fuzzy comprehensive evaluation algorithm for analyzing electronic word-of-mouth

This study evaluates tourism experiences shared through electronic word-of-mouth (eWOM) across four Chinese attractions. The objective is to develop a framework for evaluating eWOM by constructing an indicator system and implementing an analytic hierarchy process with the use of a fuzzy comprehensive evaluation algorithm. This framework is achieved by mapping more than 6000 websites related to Chinese tourism attractions and filtering over 200,000 useful reviews to measure service performance. Results indicate that ecological–biological attractions failed to make tourists feel “very satisfied” in various aspects, such as overall evaluation, infrastructure, traffic, natural environment, and social environment. Overall, the study contributes by presenting a framework that can be adopted by tourism researchers and industry practitioners to understand tourist preferences and evaluate service performance to improve service quality.     

论品牌竞争力的来源及其形成过程

品牌的本质是企业与消费者之间的无形契约,品牌反映的关系是企业与消费者之间的契约关系。本文从竞争力的经济学解释入手,分析并指出品牌差别优势是品牌竞争力的源泉,要素优势转化是品牌差别优势形成的关键,顾客感知是品牌优势通向品牌竞争力的桥梁。     

基于网络层次分析法的区域软实力评价——以江苏省为例

基于国内外软实力研究文献,考虑各指标间的交互影响、指标的数据获取和量化等因素,构建了包括三级指标的区域软实力评价指标体系,并利用网络层次分析法对江苏省的软实力进行评价。研究结果表明:江苏省的综合软实力排名为全国第二,这主要得益于其区域文化、科技创新能力以及和谐度的排名靠前,而扩散度、人口素质、区域环境以及公共服务的得分偏低。据此提出强化江苏省综合软实力的相应措施:应进一步强化各类传媒的扩散作用、完善公共服务体制以及优化投资以及居住环境等。     

Two early Swedish debates about Wicksell's cumulative process

The paper contains a survey and analysis of two debates between Wicksell and a number of Swedish economists concerning the cumulative process. The debates illustrate various problems with the analytical formulation of the cumulative process and how these problems were dealt with by the participants. Inter alia the institutional framework (inside versus outside money), excess demand or interest gap as an engine of inflation, the natural and the normal rate of interest, the relationship between the real and the monetary parts of the economy and price expectations are discussed in the paper.

Monitoring the mean and the variance of a stationary process

We deal with the problem of how deviations in the mean or the variance of a time series can be detected. Several simultaneous control charts are introduced which are based on EWMA (exponentially weighted moving average) statistics for the mean and the empirical variance. The combined X − S² EWMA chart is extended to time series. Further simultaneous charts are considered. The comparision of these schemes shows that the residual attempt must be favored if a variance change is present.
