The role of standards in innovation and diffusion of broadband mobile services: The case of South Korea

We explore the evolution of the mobile infrastructure in South Korea through the lens of actor network theory. In particular, we analyze the roles of standards in promoting, enabling and constraining innovation in broadband mobile services over a 10-year period. During this period, Korea moved from the position of a follower to the forefront of the mobile computing revolution by erecting one of the world's most advanced broadband mobile infrastructures. Our study shows how CDMA standards shaped specific configurations of actor networks that enabled the fast and aggressive development and deployment of 2G mobile infrastructures and a rapid transition to 3G services. These actor networks span three separate and critical realms of activities: the regulatory regime, the innovation system, and the market place. Our in-depth case analysis shows how specific connections and events across these three realms promoted the rapid expansion and deployment of mobile services in Korea. Our study suggests that successful innovation and diffusion of broadband mobile services are collective achievements and firms need to deploy strategies that enable them to mobilize broad socio-technical networks that include technological, institutional, political and financial resources. At the heart of such strategies, standards play critical roles as they mediate different interests and motivations among participating actors. © 2005 Elsevier B.V. All rights reserved

The purchasing performance of organizations using e-marketplaces

We apply transaction cost economic theory and perspectives in an empirical test regarding purchasing performance using electronic marketplaces. Basically, buyers can purchase products either by hopping across multiple electronic marketplaces or maintaining close relationships with a particular electronic marketplace. We investigate which is more beneficial for a buyer organization's purchasing performance in terms of price reduction and purchasing efficiency. We undertake this task by developing hypotheses and a research model and subjecting them to testing and analysis using the purchase of maintenance, repair and operations products in a large and important market, South Korea. © 2008 British Academy of Management

ERP alignment for positive business performance: Evidence from Korea's ERP market

This paper aims to examine conditions under which investment in enterprise resource planning (ERP) has a positive influence on business performance. Our empirical analysis on Korean firms that invested in ERP systems reveals how organizational integration modes need to be aligned with ERP systems for positive results from the ERP investment. Organizational integration modes refer to simultaneously used methods -people, standardization, and centralization - by which an organization coordinates and controls the activities of different departments within the same organization. The degree of alignment between ERP and integration modes is determined by the clarity of the ERP objectives, and positive results in terms of operational efficiency are correlated with the degree of alignment between ERP and these three integration modes

Consensus of corporate e-Learning system stakeholders regarding the satisfaction of end-users

The purpose of this study is to call attention to the consensus of stakeholders of corporate e-Learning system regarding success. We identified the critical success factors (contents, technical features, management, and organizational support) as major components of corporate e-Learning systems and questioned whether stakeholders' consensus on the importance of these components facilitates the implementation of these components to achieve good quality or well. We also questioned whether the influence of these components on user satisfaction could be moderated by contextual factors. Based on empirical testing of 18 e-Learning user companies, we verified that the consensus of stakeholders regarding the importance of content, technological features, and organizational support has a positive influence on the perceived quality of these factors in their e-Learning systems, which in turn is positively related to user satisfaction. The learning subjects and learning style did significantly moderate the influences of these perceived qualities on user satisfaction.Chin. Univ. Hong Kong, Li Fung Inst. Supply Chain Manage./Logist

The visual characteristics of avatars in computer-mediated communication: Comparison of Internet Relay Chat and Instant Messenger as of 2003

This research focuses on computer-mediated communication where users are represented by a graphical avatar. An avatar represents a user's self-identity and desire for self-disclosure. Therefore, the claim is made that there is a relationship between the characteristics of media and the choice of avatar. This study supports the claim by examining the difference between Internet Relay Chat (IRC) avatars and Instant Messenger (IM) avatars as of 2003 when both media had distinct characteristics and popular avatar service in Korea. Users of IRC are generally anonymous and involved with topic-based group discussions, whereas users of IM are known by their "real" names and communicate via one-on-one chitchatting. We found that avatars as symbols for users can have different characteristics in terms of self-identity and self-disclosure in different media. Gender is found to have significant moderation effect on avatar usage, whereas age is shown to have a mixed moderation effect. © 2006 Elsevier Ltd. All rights reserved

Electronic word-of-mouth, box office revenue and social media

We investigate how electronic word-of-mouth through different types of social media impacts of box office revenue across different phases of movie screening based on Roger's innovation diffusion model. We collected daily electronic word-of-mouth for movies from February to October 2012 from Twitter, Yahoo! Movies, YouTube, and blogs. The results indicate that Twitter influences on box office revenue were greater in the initial stage of a movie's opening, because of its high immediacy and diffusion characteristics. Yahoo! Movies was more influential in the late stage of a movie's opening because of high persuasion characteristics. Since blogs and YouTube contain characteristics of mass media and interpersonal communication media, we found that there were no differences for the impacts of blogs and YouTube on box office revenue between the initial and later stages.

The facilitation of stakeholder consensus for the success of corporate e-learning systems

This study examines corporate e-learning systems in terms of the role of stakeholders and end-user satisfaction. The study identifies possible Critical Success Factors (CSFs) in e-learning systems (content, technical features, management, and organisational support) and tests whether a consensus occurs among stakeholders that these factors facilitate successful implementation. The study shows that stakeholder consensus on the importance of these factors has a positive influence on perceived implementation quality in e-learning systems, which in turn is positively related to user satisfaction. The paper concludes with key implications of this finding for business and management. Copyright © 2013 Inderscience Enterprises Ltd

A multilevel analysis of the effect of group appropriation on collaborative technologies use and performance

This study develops a comprehensive model to predict and explain the use of collaborative technologies (CT) and the task performance of individual users as a result of using CT. The integrated model attempts to capture how the individual user's extent of use of CT is a function of both the technical features and the structures embedded within or created by the interactions among the technology, group, and organization. The model developed is tested using data collected from a national bank with 279 members working in 40 different workgroups. A hierarchical linear model (HLM) is used to test the hypotheses generated from the model. Results show that our integrated model provides a more complete explanation of the use of CT and task performance beyond those of the individual-level factors. The study is an early effort to develop an integrated theory to provide comprehensive insight into individual use of CT in a group or organizational context. © 2012 INFORMS
