To be a catalyst for social development, the ubiquitous cell phone must be able to access locally relevant and freely available data. The featured Web extra is a video of Computer's Invisible Computing column editor Albrecht Schmidt discussing the lessons learned from his research project on using mobile phones for education in rural Panama.
This paper analyzes the characteristics of the mobile service industry and focuses on the coopetition of many actors within the industry to explain the nature of the complex and dynamic mobile services. And the paper proposes a value network model to describe the corresponding relationship between service providers and service modules, which can help to understand the sources of value and competitive...
For mobile commerce applications are increasingly accepted, we construct a conceptual model to evaluate the effect of parasocial interaction of adopting mobile commerce application and service. And the technological and individual barriers will moderate the relationship between parasocial interaction and adoption intention.
This research examines the relationships between 3 types of Information Technology (IT) use - Internet use, cell phone use and videogame playing, on children's body weight, academic performance, (grades in school and standardized test scores), social selfconcept and self-esteem.

This paper proposes efficient method of embedding and extraction of data in Black and white pictures. The main focus of this method is on steganography in Black & white pictures. This method uses most of the flippable blocks without enforcing the odd-even features of non-uniform block. This improves the distortion in original image as blocks are remained unchanged and increases the capacity of...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
