Kim, Jea-hyun ; Kim, Jong-ki ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 1~19
DOI : 10.5859/KAIS.2015.24.3.1
Purpose This study discusses the contradictory behavior of smart-phone users who consider security is important, but they do not follow the security recommendations. We found through literature research that this contradictory behavior is resulted from a low level of efficacy. Design/methodology/approach Research hypotheses were set based on Extended Parallel Process Model, Control Theory, and Self Efficacy Mechanism. The data were collected from undergraduate students. Total of 178 data were used for the analysis. Findings Results of the analysis, first, showed that the relationship between threat and security attitude varies with the level of coping efficacy. Second, showed that the relationship between threat and fear does not vary with the level of coping efficacy. Both the groups with high coping efficacy and low coping efficacy had a statistically significant effect on the relationship between threat and fear.

Shao, Zehua ; Koh, Joon ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 21~46
DOI : 10.5859/KAIS.2015.24.3.21
Purpose Social Network Service (SNS) users feel fatigue in process of using open type of SNS like Facebook and Twitter. Compared to the open SNS, the closed SNS takes an closed form to prevent privacy exposure, and they are more practical and advantageous to form deeper social relationships. This study attempt to examine the effects of the mobile closed SNS characteristics (such as usefulness, playfulness, perceived security, psychological privacy, social influence, and belonging) on the users` continuous SNS usage intention. Design/methodology/approach This study used a mixed methodology combining in-depth interviews and empirical validation to investigate the effects of the mobile closed SNS characteristics on the continuous SNS usage intention of users. Findings Analytical results from a survey of 210 mobile closed SNS users showed that except perceived security, the effects of the five SNS characteristics on continuous SNS usage intention were significant. These findings contribute to improving the quality of mobile closed SNS services and suggesting SNS related marketing strategies.
Customer Participation into Business Ecosystems and Psychological Ownership: DaumKakao and Facebook Ecosystems
Joo, Jae-hun ; Shin, M. Minsuk ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 47~74
DOI : 10.5859/KAIS.2015.24.3.47
Purpose By participating in the business ecosystems, customers make both positive and negative impacts in the ecosystem. In particular, users of platform businesses participate in the business ecosystem as partial employees who voluntarily create and manage content. According to the organizational behavior literature, employees` psychological ownership toward the organization has an influence on the organizational competitiveness. Thus, with an assumption that customers gain psychological ownership toward the business that they participate in, it is important to analyze the process and the factors that influence their psychological ownership. This study proposes a research model that describes the process: customers undertake customer socialization, which then lead them to participate in the business-level and the business ecosystem-level activities. Through the participation, customers gain psychological ownership toward the business. Design/methodology/approach Based on a structural equation model, this study analyzes the data regarding the factors in the research model. Data was collected by surveying college students who represent themselves as Facebook and DaumKakao users. By analyzing the collected data, the relationships are validated between customer socialization and customer participations (i.e., both business-level and business ecosystem-level participation), and between the participations and customers` psychological ownership. Findings Based on the validation, this study confirms the importance of managing customers` psychological ownership and offers customers` participation by their socialization as a solution for increasing customers` psychological ownership. Also, this study proposes the business ecosystem research model as the general research framework for future research and expands the scope of strategic management from the individual level strategy to the business ecosystem wide perspective.
User`s Regret on Update Decisions of Mobile Applications
Park, Sang-Cheol ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 75~94
DOI : 10.5859/KAIS.2015.24.3.75
Purpose While new versions of mobile applications could offer users better computing environment, users are not always comfortable with them for various reasons. Considering making update decisions is important task for users, it is crucial for us to understand users` behavior and attitude on app updates. The purpose of this study is to explain why mobile users succumb to both reactance toward the update and satisfaction to the current version, ultimately leading them to feel the regret by employing three theoretical perspectives including regret theory, status quo bias theory and the dual model. Design/methodology/approach Survey data collected from 204 mobile users was used to test the research model using partial least squares analysis. The results have shown that both reactance toward the update and satisfaction to the current version have negative impacts on individuals` decisions to update, which leading to their regret after updating the applications Findings By integrating both status quo bias and regret theory in the model, this study tried to explain why mobile users feel regret in application update settings. More specifically, this study has proposed a novel framework that introduces an individual`s update decision on mobile applications.

Son, Dal-Ho ; Yoo, Seong-Pil ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 95~114
DOI : 10.5859/KAIS.2015.24.3.95
Purpose: This study was tried to investigate a structural relationship among key impacting factors and usage in SNS of government institutions. It was designed to research the processing property of SNS, the emotional property of SNS, and the service property of SNS for the SNS usage. Based on the research framework from the relationships among intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions` SNS, the empirical research model and the hypotheses were established. Design/methodology/approach: Data for empirical study were collected from 453 of total distributed 500 by the structured questionnaire survey with SNS users of government institutions. The analysis was performed from effective 432 data, and the sample was mainly consisted of men, the thirty-old, and salesmen. Findings: The results showed that the emotional and service properties in intrinsic characteristics of SNS have a significantly positive effect to the value perception and the security variable in social psychological characteristics has a significant positive effects to the trust. Finally, the value perception has positive effects on both trust and use intention of government institutions` SNS. Meaning of these results is that intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions` SNS have a significant effect on SNS usage.

A Re-analysis of the Effects of Individual Personality and Idea Stimulation on Idea Generation Performance
Jung, Joung-Ho ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 133~154
DOI : 10.5859/KAIS.2015.24.3.133
Purpose This study re-analyzes Jung 2012`s data using the time interval based analysis to examine if the process of idea generation is in good currency throughout the ideation sessions. In this way, the relationship between extraversion-introversion personality trait and ideation performance in the context of computer-mediated idea generation can be better understood. Design/methodology/approach A
factorial design was used, crossing personality differences (extraversion and introversion) with the degree of stimuli (0, 20, 40, and 80 high-quality ideas). Participants were randomly assigned to one of eight treatment conditions. The group simulator is used to measure individual level performance. The number of unique ideas generated by individuals and the exact time stamp when each idea was submitted were analyzed to compare performances. Findings The results show that introverts` performances significantly drops after about the middle stage of the ideation session, whereas extraverts do not seem to feel time constraints throughout the ideation session, resulting in superior divergent thinking, which is a major key to understand creative productivity in the problem-solving process. Since extraverts tend to yield a larger pool of ideas, another interpretation is that group composition with extraverts compared with introverts may create a logically larger group, which is important to improve the performance of idea generation group.

Lee, WoongKyu ;
The Journal of Information Systems, volume 24, issue 3, 2015, Pages 155~169
DOI : 10.5859/KAIS.2015.24.3.155
While information technology(IT) users` behaviors has been considered one of the most important research topics and studied in very many ways, `non-use` has not been focused as a research topic. However, understanding non-use provides new insights for analyzing and understanding the essential nature of IT uses with wider frames and more qualitative dimension. The objective of this study is to provide some guidelines for studying non-use. For this purpose, the previous studies for non-use were reviewed focusing on resistance, suggested potential research issues and some research methodologies based on grounded theory.
