Purpose – The purpose of this paper is to : first, examine information systems (IS) infusion from a user commitment perspective, and second, examine the formation of user commitment toward the use of IS in terms of job design. Design/methodology/approach – This study adopts a survey approach with structural equation modeling to test the developed research model and hypotheses. Findings – A survey of 236 enterprise system users shows that user commitment has a positive effect on IS infusion. User commitment, in turn, is influenced by task technology fit, technology self-efficacy, and task autonomy. Further mediation and direct effects to IS infusion are explored. Research limitations/implications – This study offers implications for research, such as explaining a driver of IS infusion; and extending commitment theory by finding antecedents of user commitment. Practical/implications – The results of this study offer suggestions to management on how to improve IS infusion in terms of user commitment and, consequently, how to develop user commitment based on the socio-technical system (STS) design. Social/implications – The study highlights the critical impact of technology autonomy on IS infusion. An individual user’s authority in using and regulating the system is required for IS infusion. Originality/value – This study has proposed a theoretical model of IS infusion based on commitment and socio-technical job design factors. © 2016, © Emerald Group Publishing Limited. Source

Although understanding the role of users' overall active behavior on a social networking site (SNS) is of significant importance for both theory and practice, the complexity and difficulty involved in measuring such behavior has inhibited research attention. To understand users' active behaviors on an SNS, it is important that we identify and classify various types of online behaviors before measuring them. In this paper we holistically examine users' active behaviors on an SNS. Toward this end, we conduct three studies. First, we classify active behaviors on an SNS into four categories using the Delphi method. Then, we develop a measurement model and validate it using the data collected from an online survey of 477 SNS users. The measures of the developed instrument exhibit satisfactory reliability and validity and are used as indicators of the latent constructs. This instrument is then used in a predictive model based on commitment theory and tested using data from 1,242 responses. The results of data analysis suggest that affective commitment and continuance commitment are good predictors of overall active behavior on an SNS. This study complements the existing research on social media, cocreation, and social commerce. Most important, this study provides a theoretically sound measurement instrument that addresses the complex characteristic of overall active behavior on an SNS and which should be useful for future research. The findings of this study have important implications for practice as they highlight managing and stimulating users' active behaviors on an SNS. Copyright © Taylor & Francis Group, LLC. Source

The usage of mobile Internet service has been on the rise as more people become to use mobile devices. WiMAX, a mobile Internet service, was first commercialized in Korea in 2006. However, after first six months, a number of users discontinued the service and switched to other Internet services. Because customer retention is important for the success of any business, this research examines the factors that affect the continued usage of mobile Internet service. A user of a mobile Internet service is both a user of technology and consumer of services. Therefore, to examine the continued usage of mobile Internet service, the authors combine the value adoption model, representing the service consumer perspective, with the information systems continuance model, representing the technology user perspective. The study is conducted in the context of WiMAX. The data was collected from 200 WiMAX users. The model developed in this study is a unique contribution to theory as it discusses the continued adoption of a commercial information system. Copyright © 2013, IGI Global. Source

A number of mobile services providers are promoting their new product by leveraging upon customers' recognition of their existing product. However, the effectiveness of such leveraging is yet to be studied systematically, especially in an emerging mobile services context. The current study examines the factors that determine the effectiveness of cross-category promotions of mobile services. On the basis of the theory of brand extension, an adoption model which reflects customers' attitude shift from parent mobile product to the promoted new mobile product was developed and empirically tested against data collected from 545 China Mobile's mobile instant messenger users. Structural equation analysis results indicate that consumers' attitude towards parent mobile product influences their attitude towards the promoted new mobile product both directly as well as indirectly through perceived fit. Consumer trust also plays an important role in the process of customers' evaluation of cross-category promotions of new mobile services. Copyright © 2013 Inderscience Enterprises Ltd. Source

From the perspective of perceived differences in technology and value between mobile commerce and Internet-based electronic commerce, the study establishes the model of consumers' usage transfer behaviour from online to mobile channel. Based on a sample of 323 respondents, we conduct logistic regression analysis. The results indicate that perceived differences in technology, namely, perceived differences in end user devices and communication network, have significantly positive impacts on transferring usage from online to mobile channel. The results also show that perceived differences in value, that is, perceived differences in convenience perceptions, personalisation perceptions, and risk perceptions, influence consumers' usage transfer from online to mobile channel significantly. Among all the factors, the effect of perceived difference in risk perceptions is negative. Managerial implications for practitioners and researchers are discussed to promote consumers' usage transfer from online to mobile channel and enhance consumers' use of mobile services.
