The Effects of Self-Congruity and Functional Congruity on e-WOM: The Moderating Role of Self-Construal in Tourism
Yang, Qin ; Lee, Young-Chan ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 1~23
DOI : 10.5859/KAIS.2016.25.1.1
Purpose Self-congruity deals with the effect of symbolic value-expressive attributes on consumer decision and behavior, which is the theoretical foundation of the "non-utilitarian destination positioning". Functional congruity refers to utilitarian evaluation of a product or service by consumers. In addition, recent years, social network services, especially mobile social network services have created many opportunities for e-WOM communication that enables consumers to share personal consumption related information anywhere at any time. Moreover, self-construal is a hot and popular topic that has been discussed in the field of modem psychology as well as in marketing area. This study aims to examine the moderating effect of self-construal on the relationship between self-congruity, functional congruity and tourists` positive electronic word of mouth (e-WOM). Design/methodology/approach In order to verify the hypotheses, we developed a questionnaire with 32 survey items. We measured all the items on a five-point Likert-type scale. We used Sojump.com to collect questionnaire and gathered 218 responses from whom have visited Korea before. After a pilot test, we analyzed the main survey data by using SPSS 20.0 and AMOS 18.0, and employed structural equation modeling to test the hypotheses. We first estimated the measurement model for its overall fit, reliability and validity through a confirmatory factor analysis and used common method bias test to make sure that whether measures are affected by common-method variance. Then we tested the hypotheses through the structural model and used regression analysis to measure moderating effect of self-construal. Findings The results reveal that the effect of self-congruity on tourists` positive e-WOM is stronger for tourists with an independent self-construal compared with those with interdependent self-construal. Moreover, it shows that the effect of functional congruity on tourists` positive e-WOM becomes salient when tourists` self-construal is primed to be interdependent rather than independent. We expect that the results of this study can provide important implications for academic and practical perspective.

Choe, Jong-min ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 25~47
DOI : 10.5859/KAIS.2016.25.1.25
Purpose In this study, the relationships among environmental information exchange with suppliers(EIES), green collaboration with suppliers, green learning by environmental information, the adoption of green supply-chain management techniques(AGSMT) (i.e., the green purchasing, product design and production, and the recovery of extra facilities and inventories), environmental performance, and the organizational performance of a firm were empirically investigated. Design/methodology/approach Data for this study were drawn from a survey of the current status of EIES levels and AGSMT usage observed in Korean manufacturing firms. In total, 500 organizations were randomly selected from a population of about 1,000 firms that are listed on the Korean stock market. In order to collect empirical data, this research administered questionnaires with the sample firms. Only chief production executives were selected as respondents. A questionnaire with a cover letter was mailed to each respondent. The survey was conducted during a 3-month period between March 2015 and June 2015. Finally, 78 valid data of the sample firms were collected. Findings The results of this study showed that EIES positively affects the green corporation and learning. According to the results, it was observed that both green corporation and green learning have a positive impact on the levels of AGSMT(i.e., the green purchasing, product design and production). It was also demonstrated that AGSMT has a direct positive impact on environmental performance. In examining the effects of environmental performance on the organizational performance of a firm, significant impact was found.

DOI : 10.5859/KAIS.2016.25.1.49
Purpose Though many information systems researchers have made various attempts to investigate the relationship between information technology capability and firm performance from diverse perspectives, we have not come to a conclusion yet with some mixed results. In this research, focusing on the adoption of Enterprise Resource Planning (ERP) systems by firms as a proxy measure for information technology capability, we reexamine whether the association is significantly positive. Design/methodology/approach Previous research on this topic had some limitations to the samples and analysis method. Some research focused only on the 1990s or early 2000s, and other studies failed to adequately compare the impact of ERP adoption on firm performance between the treatment group and the control group. In this research, extending previous analysis approaches with the matched sample comparison of IT leaders and the control group, we attempt to apply propensity score matching in combination with difference-in-difference analysis with a sample of Korean firms that adopted ERP systems in the late 2000s. We match ERP adopters and non-adopters with propensity score matching and compare their financial performance with difference-in-difference estimation between the pre- and post-adoption periods. Findings According to our analysis, we find no positive and significant relationship between ERP adoption and firm performance in profit ratios. This research shows that, contrary to the era of proprietary information systems, standardized information systems today have no additional competitive advantages over competitors.
Moderating Effects of Online Platform Business Ecosystems between Customer Participation and Psychological Ownership: A Comparison of Kakao and Facebook Ecosystems
Joo, Jaehun ; Shin, M. Minsuk ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 75~104
DOI : 10.5859/KAIS.2016.25.1.75
Purpose The business ecosystem perspective offers a new lens in which to view customers. Customers as the member of business ecosystems influence firms by participating in both the firm level activities and the business ecosystem level activities. For example, customers participate in the business ecosystems by forming interest groups, allowing their voice to be heard the within business ecosystems. Customers can also, turn public opinion around and foster the business ecosystems favorable to firms. On the other hand, as an extreme case of customer participation, customers can engage in community activities to boycott the purchase of products or services from certain firms or business ecosystems. Design/methodology/approach This study views content creation and feedback activities as customer participation in the firm level. On the other hand, word-of-mouth (WOM) and boycott activities are considered as customer participation in the business ecosystem level. This study presents a research model regarding the relationships among customer socialization, customer participation, and psychological ownership. The proposed model is validated through an empirical analysis on online platform business ecosystems. Findings When the two business ecosystems are compared, different results were drawn. In the Facebook ecosystem, boycott and psychological ownership did not have a significant relationship. However, in the Kakao ecosystem, the two had a significant positive relationship. The mediating effect of the business ecosystem type sheds a light on the mission, purpose, vision, and other values associated with the theory of the business on the customer-firm relationship. Further implications for theory and practice were discussed in this study.

Noh, Mijin ; Hwangbo, Choong ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 105~134
DOI : 10.5859/KAIS.2016.25.1.105
Purpose First, this study examines the relationship between characteristics of smartphone banking and trust of smartphone banking. Second, this study investigates the impact of perceived benefit on the trust and usage intention of smartphone banking. Finally, this study considers moderating effect of service quality in the relationships between perceived benefit and trust and usage intention of smartphone-based mobile banking. Design/methodology/approach This research uses the survey method to test its hypotheses, the survey population is smartphone baking users. A software tool called AMOS 17.0 used to analyze the research model. Findings The results showed that characteristics of smartphone banking channel like compatibility, timeliness, and mobility had a positive effect on the trust of smartphone banking. The device familiarity showed a significant positive impact on trust of smartphone banking. While the service quality moderated the relationship between trust and usage intention of smartphone banking, moderating effect of service quality in the relationship between perceived benefit and its usage intention was not significant. The results of this study could provide a theoretical framework to explain customers` decision of smartphone banking and practical implications for banking venders.

DOI : 10.5859/KAIS.2016.25.1.135
Purpose Virtual communities change the way people communicate and share information. The purpose of this paper is to find how internet social capital and individual motivations influence the information sharing in virtual communities. This study considers the social capital theory, individual motivations, information sharing, and community promotion to construct a theoretical model. Design/methodology/approach Social capital focuses on three dimensions that include 6 factors: social interaction ties, centrality, shared language, shared vision, trust and reciprocity. Individual motivations include 2 factors: reputation and enjoy helping. To confirm the research model and the hypotheses, 426 effective questionnaires were used for the final analysis. Findings The result of data analysis demonstrates that social interaction ties, centrality, shared language, trust, and reciprocity were significant in affecting information sharing behaviors. However, reputation, enjoy helping, and shared vision does not appear to have a significant influence on information sharing behaviors. The information sharing was positively related to community promotion.
Solving the Constrained Job Sequencing Problem using Candidate Order based Tabu Search
Jeong, Sung-Wook ; Kim, Jun-Woo ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 159~182
DOI : 10.5859/KAIS.2016.25.1.159
Purpose This paper aims to develop a novel tabu search algorithm for solving the sequencing problems with precedence constraints. Due to constraints, the traditional meta heuristic methods can generate infeasible solutions during search procedure, which must be carefully dealt with. On the contrary, the candidate order based tabu search (COTS) is based on a novel neighborhood structure that guarantees the feasibility of solutions, and can dealt with a wide range of sequencing problems in flexible manner. Design/methodology/approach Candidate order scheme is a strategy for constructing a feasible sequence by iteratively appending an item at a time, and it has been successfully applied to genetic algorithm. The primary benefit of the candidate order scheme is that it can effectively deal with the additional constraints of sequencing problems and always generates the feasible solutions. In this paper, the candidate order scheme is used to design the neighborhood structure, tabu list and diversification operation of tabu search. Findings The COTS has been applied to the single machine job sequencing problems, and we can see that COTS can find the good solutions whether additional constraints exist or not. Especially, the experiment results reveal that the COTS is a promising approach for solving the sequencing problems with precedence constraints. In addition, the operations of COTS are intuitive and easy to understand, and it is expected that this paper will provide useful insights into the sequencing problems to the practitioners.

Lee, Woong-Kyu ; Park, Jin-Hoon ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 183~200
DOI : 10.5859/KAIS.2016.25.1.183
Purpose Although many users change their smartphone, most may be inclined to continue using incumbent smartphone series instead of switching to new brands. Brand loyalty and switching costs are major determinants of inclinations toward incumbent smartphones. This study addresses the research question, "what roles brand loyalty and switching costs play in the purchase of new smartphones?". Design/methodology/approach A research model consisting of six hypotheses for explaining purchase intentions toward new smartphone was proposed considering inclinations toward incumbent brands. The research model was empirically tested based on purchase intentions toward the LG smartphone brand G4, employing a sample of 177 university students in Korea. The data were analyzed using the PLS technique. The results provide support for all hypotheses. Findings First, perceived inclinations toward incumbent smartphone, brand loyalty and switching costs, explained the purchase of new smartphones as well as the perception of new smartphone. Second, brand loyalty was found to play the role of moderator between switching costs and relative advantage in the purchase of new smartphone. Third, perceived aesthetics and price value had considerable influence on the purchase of brand-new smartphone.

Chae, Seong Wook ; Kang, Youn Jung ;
The Journal of Information Systems, volume 25, issue 1, 2016, Pages 201~223
DOI : 10.5859/KAIS.2016.25.1.201
Purpose As social network games (SNG) enjoy rapid growth in the market and become a major sector of the gaming industry, it is of great interest to examine the how users continuously use SNG. In SNG, the users` social interaction is the most prominent advantage of the social network, as well as the entertainment afforded by the game. This study explores the relationship between altruism, which is considered the most prominent characteristic of SNS, and the continuance usage intention, as well as the moderating role of social capital. Based on social capital theory and organizational citizenship behavior, this research model considers social bonding and bridging that are divided by social capital. Design/methodology/approach An AMOS analysis based on survey data from 223 SNG users indicated that SNG with greater altruism enhance social capital (social bonding, social bridging), which is related to the user`s satisfaction and the continuance intention of SNG. Findings Social bonding is positively related to the user`s satisfaction with SNG. In other words, social bridging positively affects the continuous usage intention of SNG. These findings help managers in developing and implementing altruistic relationships and social capital for continuous usage of SNG.
