In this study we rely on the functionalist perspective of human behavior and propose and test a balanced model of the antecedents of online game addiction among adolescents, which simultaneously focuses on motivating, and prevention and harm reduction forces. First, a sample of 163 adolescents was used for validating and refining a survey instrument. Second, survey data collected from 623 adolescents were analyzed with Partial Least Squares techniques. The findings point to several functional needs (e.g., need for relationship and need for escapism) that drive online game playing and addiction, as well as to several prevention and harm reduction factors (e.g., education, attention switching activities) that reduce game playing time and alleviate online game addiction. The effects of motivation and prevention factors on online game addiction are often partially mediated by online game playing. Implications for research and practice are discussed.

Focussing on diabetes, the paper explores the value proposition of wireless technology in enhancing patient
self-management and quality of life. Diabetics’ non-compliance with prescribed treatment plans mandates the adoption of advanced tools that can support patients through automated functions (e.g., notification reminders for taking medication), decision-support (e.g., analysis of self-test data and feedback), and anytime/anywhere communication and intervention capability (e.g., emergency consultation by healthcare practitioner). A cost-benefit analysis for the mobile self-management of diabetics suggests time and financial savings for both patients and the healthcare providers.

The Internet is believed to be a viable means for enabling and facilitating these supply chain interactions. As such, commercial web-based services that support negotiation processes have emerged (i.e., e-negotiation services). Even though these services have promising benefits for supply chain participants, they have not been accepted by most business users. Current e-negotiation studies fail to capture the substantive reasons of this low acceptance as they typically ignore real-world aspects of commercial negotiations. As such, this study argues that an action research approach is a plausible means to study this issue, and to drive changes in the e-negotiations services market. Accordingly, a research plan is outlined with guidelines and recommendations for future action research projects.

Thus, it is essential to conceptualise such mechanisms, and provide guidelines for their investigation. To this end, this paper: presents the concept of Online Dispute Resolution (ODR) services; outlines a user-centric agenda for future research in this domain. This agenda breaks this important research endeavour into manageable areas of systematic exploration, and paves the way for a better understanding of user interaction with ODR services.

In this paper, we analyze the potential risks of mobile devices loss and theft and summarize the countermeasures that can be used to cope with such risks. Based on protection motivation theory, we propose a research framework to investigate the factors that affect users' behavior to cope with the risk of mobile devices loss and theft.

A computer-based simulation was developed that describes the flows of patients and kidneys. This model provides information at various time points about the number of patients in the system who are awaiting transplants, the number of kidneys available for transplantation, the number of transplantations performed for each matching algorithm, and the number of kidneys discarded (when applicable), as well as the means and standard deviations of the HLA-match scores, number of days from registration to transplantation, and number of days (from registratio...

They often knowingly engage in certain insecure uses of IS and violate security policies without malicious intentions. Few studies, however, have examined end user motivation to engage in such behavior. To fill this research gap, in the present study we propose and test empirically a nonmalicious security violation (NMSV) model with data from a survey of end users at work. The results suggest that utilitarian outcomes (relative advantage for job performance, perceived security risk), normative outcomes (workgroup norms), and self-identity outcomes (perceived identity match) are key determinants of end user intentions to engage in NMSVs. In contrast, the influences of attitudes toward security policy and perceived sanctions are not significant. This study makes several significant contributions to research on security-related behavior by (1) highlighting the importance of job performance goals and security risk perceptions on shaping user attitudes, (2) demonstrating the effect of workgroup norms on both user attitudes and behavioral intentions, (3) introducing and testing the effect of perceived identity match on user attitudes and behavioral intentions, and (4) identifying nonlinear relationships between constructs. This study also informs security management practices on the importance of linking security and business objectives, obtaining user buy-in of security measures, and cultivating a culture of secure behavior at local workgroup levels in organizations.
