移动内容服务持续改善对持续使用意向影响的实证分析

With the development of intelligent termi-nals and mobile applications, the influence of continu-ous improvement on mobile content services to the continuance use intention is more and more signifi-cant. Based on the expectation-confirmation theory and information system continuance use theory, this paper proposes a mobile content continuance use model and puts forward related assumptions under the mobile commerce environment by introducing the continuous improvement variables. Questionnaire data are collected from 219 mobile content service users for research, and the hypothetical model is validated by the structural equation modeling. Results show that the information system continuance use model is still valid under the mobile commerce environment, and the continuous improvement on mobile content serv-ices have positive impacts on user's expectations after they have experienced certain mobile content services.

Consumer preferences of attributes of mobile payment services in South Korea

The widespread diffusion of mobile devices has led to a new method of value transfer that retains the features of mobile devices: mobile payments. Many researchers have investigated consumers’ responses to mobile payment services, which is a key indicator of the success of a service, and have examined determinants of consumer adoption. Although many studies have addressed consumer adoption of mobile payment services, only the general and abstract factors affecting adoption (e.g., perceived usefulness) have been intensively investigated. However, these studies have rarely examined the idiosyncratic and concrete aspects of mobile payment services. To improve our understanding of why consumers adopt certain mobile payment services, this study investigated consumers’ evaluations of the explicit attributes of the services. Three hundred seventy-three consumers of mobile payment services participated in an online conjoint survey. Their preference structure was generated from a conjoint analysis including five service attributes (mobile payment platform, assurance policy, mileage program, authentication method, and affiliated stores), which were identified through a literature review and focus group discussion. The results showed that an assurance policy is the most critical factor influencing consumers’ choices, and a mileage program is considered to be as imperative as the platform. We also compared the findings by two consumer clusters (safety seekers vs. platform adherers), which were classified by preference. Because this study examines concrete and specific attributes of mobile payment services beyond abstract and general adoption factors, it provides insights into consumers’ actual adoption of services.

OMA DM‐based remote software fault management for mobile devices

Mobile devices (e.g. mobile handsets or PDAs) have gained much functionality and intelligence with the growth of mobile network technologies and the increased use of mobile services. As a consequence, mobile devices have become more complex and many related problems have occurred. Specifically, sudden rebooting and freezing problems caused by software faults decrease the availability of the mobile device and cause inconvenience to end‐users. To solve such problems, academia and industry have focused on Open Mobile Alliance (OMA) Device Management (DM); this method is the international de facto standard for mobile device management. In this paper, we propose a software fault management method to remotely determine and correct problems of mobile devices based on OMA DM. We present a definition of management objects and a method to collect them from mobile devices using the OMA DM protocol. We also present a method for debugging and correcting software faults using the collected information. Finally, we present a prototype implementation and performance evaluation to validate our proposed method. Results of the performance evaluation show that our proposed method is efficient and scalable in regard to network traffic overhead and response time. Copyright © 2009 John Wiley & Sons, Ltd.
