A Structural Model to Examine How Destination Image,Attitude, and Motivation Affect the Future Behavior of Tourists

This study examines a behavioral model of wetlands tourism using variables of destination image, attitude, motivation, satisfaction and future behavior for tourists at Cigu, Sihcao and Haomeiliao in southwestern Taiwan. Empirical results indicate that destination image directly affects satisfaction and indirectly affects future behavior. Tourist attitude directly affects satisfaction and indirectly affects future behavior, while tourist motivation directly affects satisfaction and indirectly affects future behavior. Tourist satisfaction had a significant influence on future behavior, and satisfaction proved a significant mediating variable within this behavioral model.     

基于顾客网络评价的高星级酒店服务质量研究——以南京市五星级酒店为例

论文选取携程网的顾客评价数据,运用单层次模糊综合评判方法,对南京市14家五星级酒店的服务质量逐一进行评价。评价结果显示,4家酒店服务质量评价为＂较好＂,其他酒店服务质量评价均为＂非常好＂,这表明南京市五星级酒店的总体服务质量较好。论文同时分析了五星级酒店服务质量存在的问题,发现问题主要存在于客房、服务、餐饮和总体设施等方面。文末提出了酒店服务质量的改进建议。

行列式的计算方法与技巧

在高等代数中,行列式的求解是非常重要的,直接计算行列式往往是困难和繁琐的,特别当行列式的元素是字母时更加明显,因此熟练地掌握行列式的计算方法是非常重要的.行列式的重点是计算,应当在理解阶行列式的概念,掌握行列式性质的基础上,熟练正确地计算三阶,四阶行列式,也会计算简单的阶行列式的值.计算行列式的基本方法是:按行(列)展开公式,通过降阶来实现.但在展开之前往往先通过对行列式的恒等变形,以期新的行列式中能构造出较多的零或有公因式,从而可简化计算.     

基于控制单元水平的污染物负荷分配研究

污染物负荷分配方法既要考虑分配方案的公平性,又要考虑方案的可操作性。以太湖流域常州市控制单元为例,将环境容量最终分配到点源为目的,提出控制单元-行业-点源为核心的水环境容量3层分配体系,将各层分配视为既有联系又有区别的对象。在控制单元层面上实现点源污染与非点源污染削减量的分配;在行业层次上,主要考虑行业间差异对削减量进行分配;在企业层,为提高分配方案的可执行性,主要针对污染大户进行分配,使用基尼系数法对分配方案的公平性进行评价。结果表明,3层分配体系客观反映了分配量和指标之间机理和逻辑上的定量联系,以及减少污染物总量分配的主观性,为区域性水环境容量分配提供了科学的方法。     

为循环流化床锅炉运行“把关”

循环流化床锅炉以其具有热效率较高、运行稳定、操作简单、燃料适应性广、污染物排放量低的独特优点,是国内外目前竞相发展的燃煤技术。循环流化床锅炉在在实际运行中暴露出不少问题。运行周期短、点火难、的问题,笔者通过近几年来对国产循环流化床锅炉运行、技改和现场调试的经验,对循环流化床锅炉运行调试作一下简述,希望能对锅炉运行人员有所启发。     

Antecedents and Consequences of User Coproduction in Information System Development Projects

Based on a coproduction concept highlighted by service‐dominant logic, this study attempts to understand the antecedents and consequences of user coproduction in information system development projects. As a key contribution, we posit that user coproduction is influenced by social capital between users and developers; we then postulate that user coproduction determines the project outcomes. Paired data collected from both user representatives and developers by using a survey approach was used to test proposed hypotheses. The results showed that user coproduction has a positively significant influence on project outcomes, and social capital between user representatives and developers is also associated with user coproduction.     

浅析建筑企业施工管理费费率的确定

建设工程工程量清单计价规范(GB50500-2008)已于2008-12-01正式实施,规范对清单模式下的投标抱价活动中相关术语做了相应界定,其中将标底正式更正为招标控制价。招标控制价的界定,为招投标活动的合理有效进行铺平了道路。对投标人来说,接踵而来的是投标报价让利问题。如果投标人对自己施工过的项目的管理费用没有具体的量化指标,在施工竟标中将处于劣势。本文站在投标人立场,讨论施工企业管理费率的合理确定问题。     

西方经济学的微观需求理论体系及相关政策启示

在当前全球经济衰退的背景下,需求管理成为各国政府最为关注的核心政策内容,依据便是占据经济学主流地位的凯恩斯主义宏观需求理论,而该理论更深层次的基础是微观需求理论。本文按照理论发展的内在逻辑,梳理了微观需求理论体系,包括消费者的消费需求理论、市场结构理论、生产要素需求理论等局部均衡理论,还包括总体均衡、福利经济学以及市场失灵等理论。这些理论深入、细致地揭示了需求的本源涵义,给予我们重要的政策启示。     

VIX option pricing

Substantial progress has been made in developing more realistic option pricing models for S&P 500 index (SPX) options. Empirically, however, it is not known whether and by how much each generalization of SPX price dynamics improves VIX option pricing. This article fills this gap by first deriving a VIX option model that reconciles the most general price processes of the SPX in the literature. The relative empirical performance of several models of distinct interest is examined. Our results show that state‐dependent price jumps and volatility jumps are important for pricing VIX options. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:523–543, 2009
