This paper applies Multidimensional scaling techniques and Fourier Transform for visualizing possible time-varying correlations between twenty five stock market values. The method is useful for observing stable or emerging clusters of stock markets with similar behavior. The graphs may also guide the construction of multivariate econometric models.
The goal of this paper is to provide calculation formulas for the possibilistic correlation coefficient and ratio for two marginal possibility distributions of triangular form when their joint possibility distribution is defined by the product t-norm. We will also introduce an alternative definition for the possibilistic correlation coefficient and ratio when their joint possibility distribution is...
Rapid development of the Intelligent Transportation Systems (ITS) has greatly increased the traffic safety. In order to improving the safety status caused by drink driving in China, a questionnaire study was conducted with drink driving behaviors in Beijing to help understand the attitude, subjective norm, perceive behavioral control and intentions of drink driving in Beijing using the theory of planned...
The research tries to investigate the relationship among firm life cycle, managerial overconfidence and capital structure. Making listed companies in China as sample, shareholding owned by manager and its variation as a proxy for the overconfidence, and company listing age as a substitute of corporate life cycle, using OLS and panel data analysis method, we make an empirical analysis on the relationship...

Based on the investigation of 145 listed chemical firms in China, we obtain results (1) environmental disclosures level is significantly associated with environmental performance; (2) environmental disclosures...
In the e-commerce transaction process, varieties of network fraud problems occurred frequently. A C2C service reputation evaluation model under Cloud computing is Proposed. Firstly, the paper analyzes the four factors impact reputation evaluation under the cloud computing environment, and analysis the weights of each factor quantitatively. Secondly, a method to calculate the long-time reputation,...
Based on full investigation and further research of DSM, this paper established comprehensive evaluation index system, adopting fuzzy mathematics and Grey Theory. It established evaluation matrix of ray fuzzy in grey statistics, defining the weight of evaluation index according to grey correlation analysis. Evaluating the effect of DSM according to maximum membership degree principle, furthermore,...
This thesis analyzes the characteristics of cold chain logistics and establishes the index system of the location of logistics distribution center. The gray comprehensive evaluation applies gray correlation analysis as well as the AHP and studies the location of cold logistics distribution center with the organic integration of the two methods. Finally it is proved with the combination of the case.
In the strategic context of enterprise information technology, a reasonable and scientific assessment of the enterprise value-added has become the key issue of the enterprise development. Taking the cooperative effect as the core, the implementation of enterprise information changes the value of the enterprise system to a certain extent. From the perspective of the value chain, information-based business-to-business...
To understand the present situation and the affecting factors of environmental information disclosures (EID) in listed firm from heavy polluting industries, this paper operated an empirical analysis taking 82 Shenzhen exchanges a-share listed firms from heavy polluting industries as a sample. The empirical results show that the level of EID in China's listed firm from heavy polluting industries is...
In order to optimizing the rock mass mechanical parameters of Xi-Luodu hydropower station, the neural network is improved by coupling the partial least-squares regression. And so the coupling method has best explaining ability to the system, Solving the problem that neural network model is not stable and the calculation velocity is slow, and overcoming the bad effect of the many layers relativity...
Along with tourism deepening and tourism scale's unceasing expansion, tourism brings for destination economic impact, environmental impact and socio-cultural impact is increasingly clear that these effects form residents tourism impact integrated perception. The destination resident's support or not has pivotal significance to tourism sustainable development, tourism plan and tourism management. Article...
Expansion of query keywords based on semantic relationship is an effective approach to improve the performance of text retrieval. In this paper, a novel approach for text retrieval is presented. The principle of the approach is to construct a integrated semantic tree, and select candidate keywords from the tree. On the tree, all nodes are weighted based on synonymy, hypernymy, and Mutual Information...
