Lee, J., Lee, H., & Park, J.-G. (2014). Exploring the Impact of Empowering Leadership on Knowledge Sharing, Absorptive Capacity and Team Performance in IT service. Information Technology & People, 27(3), 366-386. [SSCI] Abstract Purpose – This study empirically investigates the mechanism through which empowering leadership of a team leader might influence the team performance in IT service Design/methodology/approach – The data of 315 individuals collected from 85 different IT projects through online survey is used to empirically test the hypotheses. Findings – The results confirm that team leader's empowering leadership raises the level of knowledge sharing among team members and increase the absorptive capacity of the team, and lead to better team performance. Research limitations/implications – This research theoretically presented and demonstrated the middle- and long-term impacts of empowering leadership resulting from the development of absorptive capacity as the effects of knowledge sharing in an IT project team are produced through absorptive capacity. Practical implications – The findings indicate that more effective in increasing the performance of IT project teams can be to strengthen empowering leadership than to promote traditional charisma or directive leadership. Knowledge sharing at a team level has the direct effect of improving project performance by providing information and knowledge regarding the related project, but on the other hand it contributes to making stronger the path of associating absorptive capacity with project performance Originality/value – The impact of empowering leaderships on team performance of IT project has received less research attention. Little prior research has carried out such an integrated analysis in IT service context. This study contributes to knowledge management research by identifying a key antecedent of knowledge sharing.

Developing and Validating a Citizen-Centric Typology for Smart City Services
Lee, J., & Lee, H. (2014). Developing and Validating a Citizen-Centric Typology for Smart City Services. Government Information Quarterly, 31(sup1), S93-S105. [SSCI] Abstract This study proposes a new typological framework for classifying smart city services. Intentionally focused on citizen-centricity, away from bureaucratic perspectives that most typologies have taken, this typology is derived from marketing and service science literature. The proposed typology consists of four dimensions: mode of technology (automate–informative–transformative), purpose of service (hedonic–utilitarian), service authority (voluntary–mandatory), and delivery mode (passive–interactive). This typological framework is validated with a qualitative exercise of classifying inventories of actual smart city services in practice into the framework. Exercise results revealed that the categories provided are mutually exclusive and comprehensively exhaustive in general, and useful in further conceptualization of new services by identifying gaps in reality. In practice, this typology would be useful in positioning specific smart city service under development in terms of citizen-centricity.Urban planners and administrators may use this framework in understanding the pattern of their service development. Also, this framework may provide a useful guideline for service designer pinpointing the design characteristics of old and newsmart city services from the perspective of users and customers of city services: citizens.

[KCI] IT Professionals’ Career Attitude: Q Analysis of Turnover Intentions
Lee, H. J., Kim, H. B., & Lee, J. W. (2014). IT Professionals’ Career Attitude: Q Analysis of Turnover Intentions. Journal of Korean Society for the Scientific Study of Subjectivity(28), 93-114. Abstract As information technology is becoming the critical resources for organizational competitiveness, appropriate management of IT professionals as human resources in an organization is becoming more and more important. This study explores the different career attitudes exhibited among IT professionals. Twenty four IT professionals conducted Q-analyses of thirty two Q-statements selectively screened and adopted from previous studies on turnover intentions of IT professionals. Component analysis revealed three different types of personal career attitudes among IT professionals. “Consultant” type seems to value highly of the human relationships in their work while “expert” type values highly of the work life balance with more focus on meaningfully maintaining their personal lives than increasing the value of their work. The third type, we named “developer”, values their career most highly and eagers to work for competent organizations so that they can advance their careers. All the IT professionals are concerned about the future of IT professionals in business organization and fair rewards for their technological performance. Limitations and further research are discussed.

[KCI] A Study on Antecedents of Cognitive and Affective Trust Leading to IT Service Project Performance
Yoon, J., Park, J.-G., & Lee, J. (2014). A Study on Antecedents of Cognitive and Affective Trust Leading to IT Service Project Performance. Information systems review, 16(1), 51-71. Abstract This study explores the influence of cognitive and affective trust on IT service project performance. Technology and Business expertise are posited as antecedents for cognitive trust which social bonding and relationship conflict as over for affective trust. Communication is posited as the commons antecedent for both kind of trust. A study was administered among IT Project leading in different projects. Analysis of 169 data point in general supports the research model. For building cognitive trust, Communication is formal to be must important while business expertise the second and technical expertise the third. For affective trust, the influence of antecedent are relatively smaller than the case of cognitive trust. For project performance, Cognitive trust seem to have stronger impact as IT may have direct impact as well as indirect impact via affective trust. Findings trust though the impact is smaller than the cognitive trust. In practice, this means to maintain Balanced approach in fostering trust-cognitive and affective.

[SSCI] An Empirical Analysis on the Determinants of the Length of Ministerial Tenure in Korea, 1980–2008
Hahm, Sung Deuk., Jung, Kwangho., & Lee, Sam Youl. (2014). An Empirical Analysis on the Determinants of the Length of Ministerial Tenure in Korea, 1980–2008. International Public Management Journal, 17(2), 202-223. Abstract The study of the length of ministerial tenure has received some attention by scholars of public management in Western countries. Responding to the lack of empirical research on ministerial duration in non-Western countries, this article empirically examines the determinants of ministerial duration based on the Korean Ministerial Database from 1980 to 2008. The empirical findings are as follows. First, being a female minister decreases the probability of stepping down by 1.78 times compared to a male minister. Second, political democratization after 1987 drastically increases the probability of ministerial stepping down by 3.46 times. Third, confirmation hearings after 2005 decrease the probability of ministerial stepping down by 0.53 times. Based on these empirical findings of the analysis, we can identify distinctive characteristics of ministerial duration in Korea. We argue that as the Korean political system shifts from military or authoritarian rule to democratic rule after 1987, a single five-year presidential term may set a political environment for frequent changes of ministers to allocate political spoils. |
[KCI] Explicating Moderating Effects of Conflict in the Psychological Mechanism in IT Service Engagement
Park, J.-G., Lee, H., & Lee, J. (2014). Explicating Moderating Effects of Conflict in the Psychological Mechanism in IT Service Engagement. Journal of the Korea Society of IT Services, 13(1), 1-21. Abstract In IT service quality research, the relationship between the service quality and clients' satisfaction was the focus of many studies while in relationship quality research, the influence of trust and conflict on relationship commitment seems to be the focus. In this study, these two research streams are integrated and a theoretical research model is proposed consisting of IT service quality, satisfaction, trust and relationship commitment with conflict as a moderator for the overall psychological mechanism. As satisfaction represents emotional response while trust cognitive response, this research model integrated both emotional and cognitive aspects of relationship maintenance in the IT service context. Analysis of data collected from 262 employees of global IT service firm revealed the differential effects of reliability, responsiveness, assurance and empathy on satisfaction and trust. Also, depending upon the level of conflict, the effects of reliability and assurance were found to be moderated. Further analysis revealed more profound mechanism at work relating emotional and cognitive aspects in the psychology of relationship maintenance in IT service context. Practical implications are further discussed in the conclusion. Keywords IT Service, Service Quality, Satisfaction, Relationship Commitment, Trust, Conflict, Relationship Quality |
[KCI] ICT and the Changing Nature of Work: Work Fragmentation
Lee, S., Park, J.-G., & Lee, J. (2014). ICT and the Changing Nature of Work: Work Fragmentation. Informatization policy, 21(1), 35-56. Abstract Information and communication technologies(ICT) allow and force people to work anywhere, anytime using remote databases and application systems available in real-time twenty four hours a day and seven days a week. With the real time nature of ICT, individual work is becoming more and more fragmented. Instead of working on a similar task repeatedly, individuals are required to respond to e-mails and inquiries through social networks, work on planning documents, work on presentation documents, work on spreadsheets, input necessary data on company databases, generate necessary reports from the database, run teleconference, etc., all maybe in a day’s work. Work fragmentation may impact negatively on productivity as the flow is interrupted, but it may increase the productivity by allowing people to handle multiple tasks in a shorter time period. This study explores the types of work fragmentation and their characteristics. An online survey was administered to collect data about work fragmentation and work characteristics including autonomy, complexity, flexibility, usage of ICT, etc. 300 cases were used in the analysis. Analysis of k-mean cluster indicated four different types of work fragmentation: concentrated, temporally distributed, spatially distributed, and fully fragmented.

[SCIE] A Firm's Post-Adoption Behavior: Loyalty or Switching Costs?
Park, J.-G., Park, K., & Lee, J. (2014). A Firm's Post-Adoption Behavior: Loyalty or Switching Costs? Industrial Management & Data Systems, 114(2), 258 - 275. Abstract Purpose – This study aims to investigate the influences of loyalty and switching costs toward a firm’s overall post-adoption behavior in using information system. Design/methodology/approach – A research model is developed around two constructs found in the literature – loyalty and switching costs – that are most critical in firms’ decisions on continued use of the same IS service providing company. It is empirically tested using a survey of IT decision makers in total 102 companies in South Korea. Partial least squares method is used to assess the relationships specified in research model. Findings – The findings suggest that both loyalty and switching costs have positive influences on the continuous intention to use and the inattentiveness of alternatives. Research limitations/implications – Findings are based on a single point cross-sectional survey. To further investigate the continuance of specific IT service firms, triangulation will be necessary with longitudinal and qualitative data concerning the process of decision-making, including political and contractual situation. Originality/value – The study fills the research gap in studying post-adoption behavior at the firm level by empirically testing the duality of loyalty and switching costs.

[SCIE] Communication Effectiveness on IT Service Relationship Quality
Park, J.-G., Lee, S., & Lee, J. (2014). Communication Effectiveness on IT Service Relationship Quality. Industrial Management & Data Systems, 114(2), 321 - 336. Abstract Purpose – This study aims to investigate the effect of communication effectiveness (CE) on service quality (SQ) leading to relationship quality (RQ) in IT service relationships. Design/methodology/approach – CE was decomposed into frequency, bi-directionality and quality of communication while SQ was decomposed into functional and technical qualities, and RQ into trust and relationship commitment. An empirical study is conducted testing the nomological research model consists of these dimensions, using survey method collecting data from 144 subjects. Findings – The findings indicate that good SQ can impact relationship commitment only via the clients’ trust, but not directly. Influence of functional quality is stronger on trust but technical quality also maintains significant impact. Detailed findings imply that, while communication is important element influencing perceptions of SQ, quality of bi-directional communication is more critical than simple but frequent communication. Originality/value – This study explores the direct impact of CE on SQ leading to RQ in IT service context. Previous studies rarely tested the impacts of functional and technical SQ, simultaneously. Findings of this study add values to research on service relations as well as IT services research in terms of differentiating functional and technical service qualities.
