延边朝鲜族饮食文化与旅游业发展研究

饮食文化是旅游餐饮业发展的灵魂支撑。延边拥有丰富的朝鲜族饮食文化资源,不仅为民族餐饮发展带来了不竭动力,也丰富了延边旅游文化资源。但延边朝鲜族饮食文化和企业文化培养不够完善,延边饮食文化旅游资源开发不成体系,民族餐饮业难以进行品牌建设,延边文化旅游特色明显却不被旅游者深刻体会。从而应提高延边旅游产品的服务质量,促进各民族之间饮食文化交流,弘扬延边朝鲜族饮食文化,拉动延边民族餐饮经济发展,形成延边地区支柱性产业链。     

Competition and Market Structure Reconsidered

A number of models of oligopoly in which long-run equilibrium is given by zero profit are extended to examine further the extent to which the number of firms increases indefinitely with market size. The limitations of the modelling framework are critically assessed with particular emphasis on the neglect of competition through vertically integrated economic processes. As an alternative, it is suggested that competition and industrial structure would be better studied by differentiating vertically between the different “systems of provision” through which particular goods are supplied, taking account of the integral connections between chains of economic activity, rather than generalizing across sectors and the competition within them.     

Confirmatory factor analyses of the children’s attitudes and behaviors towards animals scale in two eastern cultural contexts

The purpose of the present study was to investigate the factor stability of the Children’s Attitudes and Behaviors Towards Animals Scale (CABTA) across two eastern contexts: China and Malaysia. Confirmatory factor analyses (CFAs) were conducted on data collected from 700 Chinese mothers and 700 Chinese fathers, and 385 Malay parents of children aged 6–12 years. The CFA results suggested that the model was a good fit for both the Chinese and Malaysian responses. Furthermore, invariance testing showed that although there was factor loading invariance across cultures, the assumption of intercept invariance did not hold. This suggests that although the scale is suitable for use in both cultures, mean comparisons across contexts could be problematic. The internal reliabilities for the Typical and Malicious cruelty subscales were adequate across the samples. All findings show that the CABTA is a promising scale for international use.

中国上市公司的债务融资分析——基于理论与实证的视角

本文在实证上，通过模型筛选．采用固定影响变截距计量模型，考察了上市公司债务融资的影响因素。在实证得出的时期影响基础上，本文进一步从理论上构建了上市公司债务融资与资金成本的财务动态稳定性分析框架，发现在一定的条件下，当公司销售增长率大于资金成本率时，存在鞍点路径保证公司债务水平和资金成本率趋于某一水平，从而使公司财务保持稳定状态。基于以上实证与理论研究，本文最后得出若干结论。     

The foundations of the Tableau Économique in Boisguilbert and Cantillon

The aim of this article is to demonstrate that, despite the evident differences in form which exist between the work of Boisguilbert and that of Cantillon, the two authors use a similar theoretical framework, which provide the basic principles of the Tableau Économique. More precisely, it will be argued that, in this matter at least, there is sufficient evidence to indicate that Cantillon was influenced by Boisguilbert to some degree.     

AN ANALYSIS OF THE MOST INFLUENTIAL ARTICLES PUBLISHED IN TOURISM JOURNALS FROM 2000 TO 2007: A GOOGLE SCHOLAR APPROACH

This research note reports a study that analyzed the 100 most influential articles, which is operationalized as the most cited publications published in tourism journals from 2000 to 2007. A Google Scholar‐based software system was developed in Java to retrieve the citation information. The empirical findings show that 10.16% of the citations were from Institute for Scientific Information‐listed (ISI) journals, and that 71.64% of them were from neither ISI nor tourism journals. The most popular topics covered by these articles were psychology and tourist behavior, followed by destination image and marketing. This article contributes to the literature by providing an alternative means of assessing the impact of research into tourism.
