Online game addiction has become a common phenomenon that affects many individuals and societies. 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.

Disease management facilitated through information technology could mean a step forward towards a more effective and efficient care of patients afflicted with chronic illnesses. 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.

1) To develop a computer-based simulation to prospectively study the impacts of explicitly incorporating different equity criteria into the process of allocating kidneys to recipients, given the scarcity of this resource. 2) To assess the tradeoffs between systems that allocate kidneys based only on medical criteria, systems that allocate kidneys based only on equity criteria, and systems that consider both medical and equity criteria. 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...

This study uses an artificial neural network model to forecast quarterly accounting earnings for a sample of 296 corporations trading on the New York stock exchange. The resulting forecast errors are shown to be significantly larger (smaller) than those generated by the parsimonious Brown-Rozeff and Griffin-Watts (Foster) linear time series models, bringing into question the potential usefulness of neural network

Websites nowadays are an important and popular source of publicly available information. However, due to their exploding scale and complexity, overcoming information overload to find relevant information is a major challenge. In addition to website maps and search engines, self-adaptive websites or websites with intelligent navigation aid are very useful tools in addressing this issue. In this paper, a navigation graph-based recommendation system is proposed, in which the navigation patterns of previous website visitors are utilized to provide recommendations for newcomers. The performance of the proposed recommendation algorithm is tested using the data collected from a real world website. Experimental results reveal that the proposed system can yield satisfactory recommendations, especially to the visitors in their early navigation steps.

Widespread interest in the evaluation of human-system interfaces has led to the development of various techniques in usability engineering. Usability evaluations are usually carried out on interface prototypes. However, if the design involves hardware implementation, such as a special keypad or a control panel layout, producing hardware prototypes for evaluation can be expensive and time-consuming. One solution to this problem

ABSTRACT Marketing stimuli such as free trial has been widely used to increase user acceptance and intention to purchase information services. Information technology (IT) acceptance theories, such as the technology acceptance model and the unified theory of acceptance and use of technology, have been widely used to explain information system (IS) usage. These theories, however, do not explicitly consider the effect of marketing stimuli that would influence and shape user beliefs, attitude and behavior towards the use and purchase of new IS/IT. Echoing calls for advancing knowledge in technology acceptance, we propose a theoretical model based on expectation conformation theory to investigate the effect of marketing stimuli in the form of free trial and price of using IS on consumers’ acceptance decision process. In this study, free trial of mobile newspaper is used as the research context. A survey sample of 192 responses is used to test the model. Results suggest that the trial experience has an impact on post-trial beliefs and attitude. Perceived fee also has an effect on the acceptance of the information service when the users need to pay for the service.
