An Analysis of the Factor Structure of Jones’ Moral Intensity Construct

In 1991, Jones developed an issue-contingent model of ethical decision making in which moral intensity is posited to affect the four stages of Rest’s 1986 model (awareness, judgment, intention, and behavior). Jones claimed that moral intensity, which is “the extent of issue-related moral imperative in a situation” (p. 372), consists of six characteristics: magnitude of consequences (MC), social consensus (SC), probability of effect (PE), temporal immediacy (TI), proximity (PX), and concentration of effect (CE). This article reports the findings of two studies that analyzed the factor structure of moral intensity, operationalized by a 12-item Perceived Moral Intensity Scale (PMIS) adapted from the work of Singhapakdi et al. [1996, Journal of Business Research, 36, 245–255] and Frey [2000, Journal of Business Ethics, 26, 181–195]. The two items that were purported to measure CE were dropped due to their inability to effectively tap into the characteristic proposed by Jones. Factor analyses of the remaining 10 items supported a 3-factor structure, with the MC, PE, and TI items loading on the first factor, the PX items loading on the second factor, and the SC items loading on the third factor. These factors were labeled: Probable Magnitude of Consequences, Proximity, and Social Consensus. The authors conclude that moral intensity consists of three characteristics, rather than the six posited by Jones.     

中国入境旅游外汇收入季节调整实证分析

旅游业的行业特点决定了中国入境旅游时间序列的发展趋势中存在明显的季节变动因素及不规则因素.本文利用X-12-ARIMA季节调整方法,把中国入境旅游外汇收入序列具体分解为长期趋势因素、季节变动因素及不规则因素,并对各构成因素作了简要分析,以期能对中国入境旅游业的变动规律给出一个相对客观的认识.     

从混沌理论哲学观对旅游学混沌态及学科体系探讨

从混沌理论哲学观,对旅游学混沌态进行了分析,将其分为"前科学阶段"混沌态和"内在随机性"混沌态,认为旅游学的"内在随机性"决定了旅游学多学科、交叉性的特点.从混沌学的"初值敏感性"理论,阐明了旅游研究应以游客为初始路径的观点.根据混沌理论,确定了体验和服务是旅游系统的两个奇异吸引子,并分析了它们之间的联系与区别.从旅游系统动力机制分析,提出了由体验维、服务维、影响维和信息、技术维等4个维度构成的旅游学科体系框架.     

基于因素分析的区域旅游竞争力评价模型研究

竞争力评价是近年学术研究的热点.本文首先回顾了我国区域旅游竞争力评价的相关研究,然后从分析区域旅游竞争力的影响因素入手,构建一个评价区域旅游竞争力的多层次指标体系,并利用因子分析法对指标体系进行定量分析,建立相应的综合评价模型.     

旅游产品散论

目前学界对旅游产品的概念存在不少分歧,本文择取如下问题加以讨论:旅游产品是否包含媒介要素、是否是一种经历或体验、是否是商品、是否包含目的地出售的实物形态商品以及是否包含旅游资源.本文认为,媒介要素是旅游产品的必要组成部分,不能把旅游产品看作经历或体验,旅游产品是商品,旅游产品中不包含旅游地出售的旅游纪念品等实物形态商品,也不包括旅游资源.本文着重讨论了旅游资源与旅游产品的关系,提出旅游资源不是旅游产品或产品的一部分,而是、也仅仅是旅游产品生产要素中狭义的土地要素.     

跨区域旅游协作因素分析及其机制探讨——以桂西民族地区为例

本文在景区旅游竞争力构成因素研究的基础上,将区域间进行旅游协作相关性密切的要素分为旅游协作决定因素、旅游协作支持因素和旅游协作保障因素3部分,对其作了初步的内涵界定,并采用问卷调查方法对各旅游协作因素的重要性进行了排序.在此基础上,本文选定了桂西民族地区有一定代表性的20多个景区,通过实地考察和资料分析相结合,采取层次分析法对所选样本进行了较为详尽的分析、评定.初步得出了各景区的旅游协作总系数以及根据协作要素的不同层次分析而确定的协作类型,从而为各景区明确自身在区域协作中所处的地位和发展方向、相互间在协作过程中的空间布局及其调整等方面的基础性研究作了尝试性的探讨.     

中俄天然气合作博弈分析

Interdependencies in the Dynamics of Firm Entry and Exit

This paper investigates the interdependence between firm entry and exit from an industrial dynamics perspective. The paper discusses how entry and exit rates in industrial sectors are affected by previous exit and entry rates. Economic theory presents two different approaches to how entry and exit of firms are interrelated, the multiplier effect and the competition effect. This paper intends to investigate which force is the predominant one, for entry and exit patterns, respectively. The empirical analysis is based on data for 25 Swedish manufacturing industries at the 2-digit SIC level, during the period 1991–2000. In the estimation work the study applies a dynamic panel data approach as suggested by Anderson and Hsiao [Journal of the American Statistical Association, 76:598–606, 1981] and Arellano and Bond [Review of Economic Studies, 58(2):277–297, 1991]. With respect to entry, the empirical results support the multiplier effect such that entry stimulates future entry, but also a competition effect such that past exit induces additional entry. With regard to exit, on the other hand, the competition effect rules, implying that previous entry causes subsequent exit and previous exit reduces subsequent exit.
