考虑残值变化和顾客异质性的零售商定价与库存决策

本文研究策略型消费者对零售商的定价和库存决策的影响。与以往的研究假设残值固定不变,且消费者均为策略型消费者不同的是,本文考虑了顾客的异质性以及残值由清仓期库存决定这一特点。本文的研究表明:在消费者均为策略型消费者,且清楚零售商将采取残值定价策略的情况下,零售商可以通过数量保证策略来提高自身的期望利润,降低库存订货量。在考虑顾客异质性的条件下,当零售商采取估值定价策略时,零售商的最大期望利润与短视型消费者在市场上的比例成正相关。并且,存在一个唯一的阈值点,当短视型消费者在市场上的比例高于这一阈值点时,估值定价策略优于保留价格定价策略,反之,则保留价格定价策略更优。     

考虑竞争者进入威胁的易逝品动态定价机制

本文研究了同时考虑竞争者进入威胁和消费者行为的易逝品的动态定价机制.依据策略性和忠诚性两个维度,将市场中的消费者分为策略型忠诚者、策略型转换者、短视型忠诚者和短视型转换者四种类型.建立了在位企业、竞争企业与策略消费者间的两阶段动态博弈模型,通过均衡求解与分析,探讨了在位企业和竞争企业的最优价格机制以及消费者行为对企业定价行为和均衡收益的影响,深入分析了竞争者的进入行为对在位企业定价和收益的影响,以及消费者策略行为和转换行为与竞争者进入行为间的交互作用机制.研究表明:在位企业可以依据策略消费者的比例,采取智能的动态定价机制,实行或放弃对策略消费者的跨期价格歧视,最大化自身收益;消费者策略行为会降低在位企业的绩效却能够提高竞争者的绩效;竞争者的进入并非总是对在位企业不利,在一定条件下,竞争者的进入有利于提高在位企业的绩效;在位企业通过多种方式培养自己的忠实顾客,不仅能够应对竞争者的进入威胁而且能够缓解消费者策略行为的负面影响.     

顾客心理安全感对网络服务消费行为作用的实证研究

尝试把心理安全感概念引入网络消费行为解释中,探究顾客心理安全感对消费行为的作用。利用结构方程路径分析,发现消费者心理安全感在感知风险和消费行为间具有中介作用,且顾客感知风险对消费行为不具有直接效应,故认为当顾客感知风险带来顾客心理安全感缺失时会影响消费行为。研究结论深化了感知风险对消费行为作用机理的认识,对指导网站服务营销的针对性,寻求促进网络消费的措施和方法具有理论意义。

电子商务环境下的消费者行为研究

本文首先分析了电子商务环境下消费者行为相对于传统的商业模式所表现的特点:消费市场的细分化、服务需求的主流化、选择范围的扩大化和购买行为的理性化、生产和流通循环的直接化;然后分析了影响消费者网上购买行为的宏观和微观因素,最后建立了电子商务环境下的基于计划行动理论的消费者行为模型。     

Prevalence and risk and protective factors associated with HIV-related behavior among transgender people in Hong Kong

Abstract

This paper presents findings from the first large-scale quantitative study into HIV-related behavior among transgender people in Hong Kong. A survey of 195 transgender people found that only one-third of those who had engaged in sexual behavior in the past 3?months reported consistent condom use. Stable relationships, beliefs in low HIV transmission risk, and condom inaccessibility were cited as reasons for inconsistent condom use. The HIV testing figures were also strikingly low. This study demonstrates an urgent need for addressing HIV issues among transgender people in Hong Kong as there are currently no such specific services.     

Body image,self-esteem,and behavioral risk for chronic disease among college students: Additional evidence for integrated prevention

Abstract

Objective: To examine associations between two body image constructs (body appreciation and body satisfaction) and five health behaviors (diet, physical activity, weight management, tobacco exposure, and alcohol intake) associated with risk for chronic disease, controlling for self-esteem. Participants: Three hundred and forty-four college students enrolled at a large, public university in the southeastern US. Methods: Students completed an online survey composed of measures of body appreciation, body satisfaction, self-esteem, and frequency of engagement in preventive health behaviors. Hierarchical linear regression models were used to assess relationships between constructs. Results: Body appreciation, but not body satisfaction or self-esteem, significantly and positively predicted engagement in diet-, physical activity-, and weight-related health behaviors. No associations were found for substance use outcomes. Conclusions: Results illuminate health risks among college students and provide additional evidence to support the development of holistic preventive interventions that simultaneously address aspects of mental and physical health among college students.     

论审美活动的历史沉沦

西方美学的根本失误在于以“理性图式”取代了“审美图式”。中国美学的根本失误在于以“伦理图式”取代了“审美图式”，后现代美学的根本问题存在于以“欲望图式”取代了“审美图式”，它本质上是一种“被理性异化的欲望本身”。这是中西美学走向其历史沉沦的根本。
