Cross-Media Integration of QR Code: A Preliminary Exploration

ABSTRACT

This study examines the effectiveness of Quick Response (QR) code loyalty campaigns in two phases. In Study 1, qualitative perceptions of QR code are examined through key informant focus groups. Participants express their positive as well as negative opinions about the use of QR code. In Study 2, we examine the effectiveness of QR code loyalty campaigns in “winning back” inactive customers in terms of repeat purchases. The study manipulates information privacy concerns, level of involvement, and timing of rewards. Results from a scenario-based experiment suggest that when consumers are concerned with privacy disclosure, delayed rewards, rather than immediate rewards, induce greater loyalty among inactive consumers. By the same token, a low-involvement service, rather than a high-involvement service, is likely to develop greater loyalty. Furthermore, there is a significant interaction effect between the timing of the reward and the level of involvement. However, when consu
 mers are not concerned with privacy, neither main effects nor interaction effects are observed. In closing, implications are discussed while limitations are recognized and future research is suggested.

Keywords: QR code; loyalty; mobile device; privacy concerns; reward

Antecedents and Distinctions between Online Trust and Distrust: Predicting High- and Low-Risk Internet Behaviors

Yong-Sheng Chang Tamkang University, New Taipei City, Taiwan

Shyh-Rong Fan Hsiuping University of Science and Technology, Taichung City, Taiwan pp.149-166

ABSTRACT

While previous studies have investigated the determinants and consequences of online trust, online distrust has seldom been studied. Assuming that the positive antecedents of online trust are necessarily negative antecedents of online distrust or that positive consequences of online trust are necessarily negatively affected by online distrust is inappropriate. This study examines the different antecedents of online trust and distrust in relation to consumer and website characteristics. Moreover, this study further examines whether online trust and distrust asymmetrically affect behaviors with different risk levels. A model is developed and tested using a survey of 1,153 online consumers. LISREL was employed to test the proposed model. Overall, different consumer and website characteristics influence online trust and distrust, and online trust engenders different behavioral outcomes to online distrust. The authors also discuss the theoretical and managerial implications of the
  study findings.

Keywords: trust, distrust, prospect theory, low- and high-risk Internet behaviors

The life cycle of open source software development communities

ABSTRACT

Drawing from the concept of entropy in open systems theory, this article contributes to organizational theory by illuminating organizational life cycle theory and exploring open source software development communities (OSSDC) with quantitative longitudinal data. In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online co
 mmunities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Keywords: Online communities; open source software development; life cycle.

Understanding the Acceptance of Mobile Health Services: A Comparison and Integration of Alternative Models

ABSTRACT

The advancement of mobile technology and the increasing importance of health promote the boom in mobile health services (MHS) around the world. Although there have been several studies investigating the health technology acceptance behavior from a variety of theoretical perspectives, they have not provided a unified understanding. To fill this research gap, this paper: (1) reviews the health technology acceptance literature and discusses three prominent models (e.g., the technology acceptance model, the theory of planned behavior or the unified theory of use and acceptance of technology, and the protection motivation theory), (2) empirically compares the three models, and (3) formulates and empirically validates the unified model in the context of mobile health services. In the unified model of health technology acceptance, we propose that users’ intention to use mobile health services is determined by five key factors: performance expectancy, effort expectancy, social infl
 uence, facilitating conditions, and threat appraisals. The results show that the unified model outperforms the three alternative models by significantly improving the R-squares. Finally, the implications for theory and practice are put forward.

Keywords: mobile health; technology acceptance model (TAM); protection motivation theory (PMT); theory of planned behavior (TPB); the unified theory of use and acceptance of technology (UTAUT)
