Abstract ：

The rapid development of ubiquitous technologies and mobile devices has made ubiquitous commerce (U-commerce) the next business wave. U-commerce enabled merchants with new opportunities to provide personalized services and novel shopping experiences to customers. Applying affordance theory, this study builds a research model that explains the consumer cognitive assimilation process in U-commerce and explores hedonic and impulsive consumption. This study played the U-commerce video for participants before they answered the questionnaires. The empirical results show that context-aware facilitation and social facilitation contribute equally in explaining cognitive assimilation. Meanwhile, cognitive assimilation significantly influences both hedonic consumption and impulsive consumption. This study sheds light on the two important facilitations derived from the U-commerce environment and also reveals the determinants for two types of interesting purchase behaviors in the U-commerce context. © PACIS 2017.

Abstract ：

This paper studies the sequential decision under constraint conditions. This paper studies relation of status data, data quality to decision results, data worth and the rules of the designated solution. This paper uses simulation model, the Bayesian formula and the minimal expectations value principle, analyzes characteristics of data to decision results by changing the value of different model parameters. This paper's differences are constructing sequential decision under constraint conditions, and introducing match variable instead of the single variable, replacing expectations maximum principle with expectations minimum principle. This paper's findings show that high quality and stable solutions depends on the change of which state data and(or) data quality play the leading role. This phenomenon is interpreted through the closure property of status data value and data quality value, and the expected value principle. The merit of this paper lies in that we not only extract and solve one category important but unsighted decision problem, but also construct a set formula to analyze the relation of data to decision quality. Our conslusions are universal to the above decision category and not limited to emergency decision.

Abstract ：

The data and information usually are inaccurate in emergency decision, which influence decision results and quality. The paper aims explore how to determine relation of data quality to decision results and quality in emergency decision-making. The paper methods apply Bayes decision, involve prior and posterior probability. The paper context includes emergency-making generalization model, match function, maximum expected value function, data quality value, sensitivity analysis of data result and quality, inspect a case. The paper contribution and innovation lie in that supplements a new angle and method to explore relation of data quality to decision result and quality

How to build efficient e-markets for agricultural products has been a concern of China. This paper is to explore the agri-food e-markets of China from the aspect of evolutional functions, so as to shed light on the sound development of e-markets. A functional matrix is built based on the literature review of e-markets, and a survey of Chinese agri-food e-markets is conducted. It is concluded that agri-food e-markets of China show a binary scheme, with ordinary e-markets still in a preliminary stage, and bulk e-markets being in a priority to provide most functions. Future development of the ordinary e-markets should focus on providing solutions for settlement and after-sales phases. Bulk e-markets need to make efforts in providing collaborative process management. © 2011 IEEE.

This paper is to tell whether the weighted rating system is efficient to well distinguish the good sellers. It is designed to first test the relationships between weighted ratings and the sellers' sales - tagged price, charged price, sold probability and sold quantity, and then compare the stresses of the relationships under the weighed settings and the unweighted settings. The second biggest Chinese site paipai was chosen, and an identical prepaid card was selected for the study. It is surprising to find that the weight does not greatly matter: (1) the relationships between ratings and the sellers' sales conform to the results of prior literature; (2) no significant changes are made, though the sellers' tagged price showing a marginal slight decrease.

This paper analyzes a differential game model describing the interactions between the government agency and the seller in C2C electronic marketplace and solves it by using Pontryagin maximum principle. We show that the open-loop equilibrium is subgame perfect. The optimum steady-state control strategies of both sides are derived under symmetric and asymmetric information, and results are compared in order to provide guidance for the government to supervise sellers with false behaviors. © 2010 IEEE.
