The appeal of sustainability in luxury hospitality: An investigation on the role of perceived integrity

This research investigates the effect of a luxury hotel's marketing communication strategy on consumers' willingness to book a room. In particular, the article compares two types of communication message: one that mainly highlights the hotel's attention to environmental sustainability and the other that focuses on customer service. The paper tests the hypothesis that a sustainability-focused communication leads to a higher willingness to book a room (compared to the customer service-focused strategy) because it increases consumers' perceptions about the hotel's integrity. Moreover, the study proposes that consumers' dispositional environmental concern magnifies this effect. One online and one realistic field experiment provide empirical evidence for the research hypotheses. This article contributes to the literature on sustainable luxury tourism and hospitality by proposing a novel theoretical framework, grounded in perceived hotel integrity, to explain why consumers might react positively when learning that a luxury hotel is committed to sustainability.     

高科技社会我国风险沟通重塑

高科技社会衍生“人为风险”，西方发达高科技国家倡导新型风险沟通，而后发场域由于系统落差，呈现出迟滞型风险沟通。通过构建全球化高科技风险社会、全球本地化风险沟通的新分析框架，发现高科技社会我国风险沟通面临着风险的社会放大、气泡结构、路径互动阙如、手段叠加、目标战略缺失、过程碎片化等迟滞困境。通过创新理念、吸纳型风险沟通、复合式路径、平衡化手段、连续统、政府学习和政府职能的“七位一体”再造，可有效重塑高科技社会我国风险沟通，推进国家风险治理体系和治理能力现代化。

无限缓存下自相似网络通信量复用策略

研究了自相似网络通信量的统计复用策略。首先讨论了在采用FIFO(First In First Out)服务策略且缓存趋于无限大时，满足一定溢出概率要求的统计复用带宽要求，然后对这种情况进行了仿真分析。研究表明网络通信量的自相似特性对复用增益有较大的影响，并且自相似性越强、复用通信量数量越大，所取得的复用增益越大，这对于网络设计是很重要的。

Modelling exchange of probabilistic opinions

Summary. This paper studies how communication or exchange of opinions influences correlation of beliefs. The paper focuses on a situation in which agents communicate with each other infinitely many times without observing data. It is an extension to the ‘Expert Problem’ in Bayesian theory, where the informational flow is asymmetric. Moreover, this paper generalizes the existing literature of communication that employs the common prior assumption (CPA) by allowing for heterogeneous beliefs. Some basic convergence results are shown in contrast with the results obtained under the CPA. Furthermore, several economic implications of the basic results are provided.
