Locating experts using social media,based on social capital and expertise similarity

Information and communication technologies boost knowledge activities, both within and across organizations, and in online communities. Determining how to effectively search for and find experts via social media has become a critical issue. Although social capital is a key driver of knowledge contribution, we have not addressed the issue of how to locate experts based on their social capital. Systems designed to locate experts typically recommend such experts based on keywords, thus failing to consider any semantic similarity between their areas of expertise and the problem domain (a.k.a., “expertise similarity”). The system designed and developed in this study recommends experts based on both their social capital and expertise similarity. We measure the social capital of experts based on their consultant service relationships and their friendships. We conduct a field experiment to evaluate user satisfaction and the system’s knowledge-contribution predictive capability. The results show that the proposed system is of high quality and delivers excellent information. Hence, users expressed their intention to use this system. In addition, the positive effect of social capital on the knowledge contribution is verified from the perspective of user behavior.     

A multi-criteria expert decision system for investment decisions: The case of commercial real estate investments in China

Consistent with the rapid growth of the Chinese economy and its commercial real estate (CRE) market, evaluating CRE investments in China is becoming an important application area where a multi-criteria expert decision system can make a significant contribution. We used a multi-criteria expert decision system to evaluate ten actual CRE investments in China. Based on thirty-one industry experts, we identified key decision factors to consider when evaluating different CRE investment projects and determined their importance weights. We then evaluated whether or not the ten CRE investment projects were considered to be successful, taking into account the unique characteristics of each CRE investment project. We finally compared the evaluations for the ten cases with their actual performance using four different performance indicators. The results showed that the evaluations had at least 87.5% accuracy across four different performance indicators. As probably one of the first systematic and in-depth scholarly studies to evaluate CRE investment projects in China, this study contributes to a better understanding of such evaluations and helps CRE investors evaluate CRE investment projects in a more informed fashion.     

论WTO争端解决机制的缺陷及我国的应对措施

WTO争端机制地已经成功地解决了许多国际贸易争端,对世界贸易和投资产生了重大的影响。但机制仍受强权政治的干扰,对发展中国家而言是一个沉重的负担,对此应进行相应的改革完善。中国作为最大的发展中国家应完善立法、加强国际合作,培养法律人才及采取其他的应对措施。     

Name-Based Behavioral Biases: Are Expert Investors Immune?

The market comprises investors with a broad range of expertise. As a result, investors may make decisions differently from one another. Research reveals that investors use name-based heuristics, or short-cuts, including alphabetical ordering (Itzkowitz, Itzkowitz, and Rothbort []), name fluency (Anderson and Larkin [], Green and Jame []), and name memorability (Grullon, Kanatas, and Weston []) when trading stocks, resulting in irrational decisions. Because experts and novices process information differently, name-based biases may not affect all investors equally. The authors test and confirm the hypothesis that, compared to novices, expert investors are relatively immune to name-based biases.

Consensus formation during strategic change

This paper offers a refined conceptualization of consensus formation and demonstrates in three organizations how this conceptualization enables us to uncover new patterns of consensus building. It describes a longitudinal study which investigated consensus formation in three organizations undergoing major strategic change. The study explored whether consensus building occurred during the strategic change and, if so, how. Initial participants of consensus were also investigated as well as changes in the scope of participants in consensus. Consensus building did occur, but contrary to some views less through an increase in the strength of consensus and more through an increase in the scope of consensus. Additionally, initial consensus was not located among members of the top management team, but more within an interest group whose members benefited from the given direction of the change.

Exploring the role of expert power in channel management: An empirical study

Expert power is recognized as a non-coercive source of power, which can be effectively employed in the context of channel management. The paper attempts of look at the impact of expert power on certain channel relationship variables. The behavioral variables considered in the study are the use of behavior-based coordination strategy, use of problem-solving approach for conflict resolution, collaborative communication, cooperation and trust. An empirical study conducted among the computer hardware dealers in India supports the hypothesized linkages between expert power and other relationship variables.     

Group Consensus: The Impact of Multiple Dialogues

The research results on group consensus have been ambiguous within the field of Group Support Systems (GSSs). Some research studies have shown that groups using multiple communication channels produce more ideas, and more unique ideas than groups using a single communication channel. In addition, a second set of research findings have shown that groups using GSSs report group members hold less consensus with the group's decision. This research studies more closely how these two characteristics; communication channel and consensus, interact. Specifically, can less consensus be a function of the choice of channels used in problem solving. The results show that groups using a single communication channel generate more actual consensus than groups using multiple communication channels. Furthermore, the single channel discussions provide more integrative comments and these integrative comments may help explain the difference in consensus. These results suggest that those striving for consensus from group members should consider production methods used to create the information that is to be used in the decision.
