Consumers’ responses to ambivalent online hotel reviews: The role of perceived source credibility and pre-decisional disposition

Electronic word-of-mouth (eWOM) is prevalent in today's lodging market and has potential to influence consumers’ decision making. This study investigated how the presence of online reviewers’ personal identifying information (PII) may affect consumers’ processing of ambivalent online hotel reviews and hotel booking intentions. The results of an experiment with a sample of 274 undergraduate students indicate that the presence of PII positively affects the perceived credibility of the online reviews. When coupled with ambivalent online reviews, the presence of PII significantly lowers consumers’ hotel booking intentions.     

虚拟集群式旅游供应链模型构建研究

文章基于旅游供应链理论研究动态与现代信息技术发展态势,提出以信息拉动式为特征的在线旅游供应链(e-tourism supply chain)的理念。从集群式供应链视角,分析了虚拟集群式旅游供应链建立的动因,构建了虚拟集群式旅游供应链理论模型。文章通过创新旅游供应链研究视角,借鉴产业集群与供应链管理耦合研究理论,试图在赛博空间(Cyberspace)里,构建起虚拟集群式旅游供应链的理论框架,可分成4个部分:(1)旅游者信息链,是围绕着每个旅游者需求信息的一条"信息拉动式供应链",在此基础上形成旅游企业旅游服务大规模定制链;(2)旅游服务定制链,旅游企业在以"旅游者"为中心的信息链上提供即时响应、即时采购、即时生产、即时销售的敏捷制造服务,同业性旅游企业合作服务于旅游者;(3)信息共享平台,包括旅游者需求汇集、统计、分流平台,旅游企业沟通平台和旅游评价平台;(4)专业化辅助企业,具有弹性专精的优势,缓解大规模标准通用化服务提供和市场的定制化随机要求(stochastic demand)之间的矛盾,满足了旅游者对定制化旅游服务需求。

矿量分级制式观念有待创新

始自1909-1910年通行各国的多种矿量分级制式,在原则上是都以所谓地质信息的可靠性为标志。本文所倡议的矿量分级制式,将以总开发效益的可靠性为标志另行构筑,它能使矿块级别-吨位-品位指标的内在联系从幕后走到前台,使勘查者的各级矿量与开采者的三级矿量贯通一气。级差品位指标制在国内运行四十多年的成效,就是在块段吨位足够大的前提下尊重级别-品位依存关系的例证。     

分布式地矿点源信息系统的构件化体系结构设计

应用数据集市技术、分布式构件技术以及Java技术,本文提出了一种以Internet为运行平台的新的分布式地矿点源信息系统设计方案。文中从数据库体系结构和应用系统的体系结构方面,探讨其构件化体系结构设计的原理与方法。实践结果表明,这种新的设计方案可以使该系统的新一代产品以更低的代价发挥更大的效益。     

A field experiment investigating age discrimination in four European labour markets

In a field experiment investigating age discrimination, pairs of men, aged 27 and 47, inquired about employment as waiters in towns across England, France, Germany and Spain. Statistically significant discrimination against the older waiter was found in all four countries, but it was considerably higher in France and Spain than in England and Germany.     

Innovation and the precautionary principle

Recent environmental policies favour the polluter pays principle. This principle points out the pollutant financial liability for the eventual incidents induced by his activities. In this context, we analyse the decision of an agent to invest in new industrial activities, the consequences of which on human health and the environment are initially unknown. It is not possible for him to delay investing, but the agent has the opportunity to acquire information and to reduce the cost of an accident. This allows the agent to reduce uncertainty regarding dangers associated with the project and to limit potential damages that it might cause. However, the agent's chosen level of these actions may be considered as insufficient and not acceptable by society as response in the face of a possible danger. Precautionary state regulation may then be introduced. We appreciate that this regulation may slow down innovation and may favour innovation in countries with less safety requirements. We find that the agent may get around the goal of the regulation by ignoring the information on the dangerousness of its project. We then propose some policy tools which stimulate innovation and impose a certain level of risk considered as acceptable for society to the agent. Finally, we use a numerical analysis based on the Monsanto Company for studying the agent's behaviour with different regulatory frameworks.     

基于熵权理论的上市公司透明度评价研究

根据熵权法的基本原理,构建了上市公司透明度评价体系,并运用实证研究的方法,以2004年深交所信息披露考核结果为优秀和不及格的公司为研究样本,考察了代表公司特征和公司治理结构特征的9个指标与上市公司信息透明度的关系,并对样本公司透明度进行了综合评价.     

信息产业发展水平综合评价体系研究

科学地分析信息产业发展水平是制定信息产业相关政策的重要基础。通过对信息产业发展阶段特征的综合分析,提出了一套科学的信息产业发展水平评价指标体系,运用层次分析法对评价指标进行综合分析,对国家信息产业发展水平作出了基本评价。通过对12个国家信息产业发展水平进行综合评价,对不同国家信息产业发展水平进行聚类分析,从而分析总结出信息产业各个发展层次的主要特征,为进一步制定信息产业发展的相关战略和政策提供了理论依据。     

非对称信息下权力运行与监督制约中的“诺思悖论”

权力主体拥有信息优势。权力主体之所以拥有信息优势,是因为他更接近信息源,同时由于人本性所具有权力倾向动机所产生的信息垄断。而监督制约是监督主体针对权力主体的权力运行所采取的约束手段,监督主体处于维护权力正确运行的被动而且明显的信息劣势地位,但也具有自己的相对独立性。在这种情况下,权力主体与监督主体之间存在严重的非对称信息问题。从这种非对称信息大格局下审视权力运行与监督制约,实际上可以把问题扩展为权力主体与监督主体所拥有的信息不对称状态下存在"诺思悖论"问题。然而,权力主体与监督主体非对称信息的体制性根源究竟何在?其相悖的社会动力机制又是怎样的?诸如此类的问题,都迫切需要作进一步的探讨。正是基于这样一种思考,本文拟在现有理论的基础上,尝试利用信息经济学的观点作为观察问题的新视角,予以对问题的剖析,并探求解决其困难的可能路径,这就是本文考察权力运行与监督制约问题的理论和方法。
