We analyze mobile computing trends in research and practice between the years 2000-2009 with an inductive categorization of 806 articles in nineteen leading academic, crossover, and practitioner outlets. We integrate this categorization with previous research in mobile commerce and e-business in order to provide the most comprehensive categorization to date. Using this categorization, we next investigate trends in the discussion and research on mobile computing. From these trends, we develop a comprehensive framework that addresses both where mobile computing research has been over the past ten years, but also areas of opportunity for future research. Results indicate research is required in the areas of: (a) IT value stream proposition (both within and outside the firm), (b) human-computer interaction (designing usable mobile computing systems), (c) legal/ethical issues surrounding mobile computing-enabled activities, and (d) organizational/societal impact and change precipitated by mobile computing technologies.

Information quality" is arguably the most important information systems construct, and yet there exists no common definition of this construct, or set of recommendations for its appropriate usage and measurement. This paper explores the nature of information quality as a contextual, or fit-based, construct. Using this contingency approach we see that the definition of information quality is dependent on context, and instead of containing a clear maximum (or maxima) is rather comprised of tradeoffs. A call is made for restraint in uniform definition and measurement of information quality, acknowledging its appropriate use based on a specific construct-context fit.

Unhealthy lifestyles cost businesses, governmental organizations, and the U.S. military billions of dollars every year, not to mention intangible costs associated with increased mortality. This study implemented a low-cost cognitive-behavioral motivational intervention to effect behavioral change in high-risk civilian employees working for a U.S. military organization, with accompanying improvement in certain health indicators after 120 days compared with a control group. Our analysis of these results led to two conclusions: first, low-cost cognitive-behavioral motivational treatments can improve both behavior and health, and second, tentative results indicate a fully mediated relationship may exist among the cognitive variables of locus of control and self-efficacy, vice the predicted parallel relationship. Overall, we assert that effective implementation of an intervention like the one used in this study might lower the U.S. Air Force's health care bill by as much as $40 million, improve employee efficiency and mission capability, enable healthier lives, and prevent premature death.
