Smartphones
Many of the research approaches to smartphones actually regard them as more or less transparent points of access to other kinds of communication experiences. That is, rather than considering the smartphone as something in itself, the researchers look at how individuals use the smartphone for their communicative purposes, whether these be talking, surfing the web, using on-line data access for off-site data sources, downloading or uploading materials, or any kind of interaction with social media. They focus not so much on the smartphone itself but on the activities that people engage in with their smartphones
Insights in the cost of continuous broadband Internet on trains for multi-service deployments by multiple actors with resource sharing
The economic viability of broadband Internet services on trains has always been proved difficult, mainly due to a high investment cost and low willingness to pay by train passengers, but also due to unused opportunities such as non-passenger services (e.g. train performance monitoring, crew services) and optimization of the resources consumed to offer Internet services. Evaluating opportunities to improve the return on investment is therefore essential towards profitability of the business case. By efficiently sharing resources amongst services, costs can be pooled over several services in order to reduce the investment cost per service. Current techno-economic evaluation models are hard to apply to cost allocation in a multi-service deployment with multiple actors and resource sharing. We therefore propose a new evaluation model and apply it to a deployment of Internet services on trains. We start with a detailed analysis of the technical architecture required to provide Internet access on trains. For each component, we investigate the impact by the different services on resource consumption. The proposed techno-economic evaluation model is then applied in order to calculate the total cost and allocate the used and unused resources to the appropriate services. In a final step, we calculate the business case for each stakeholder involved in the offering of these services. This paper details the proposed model and reports on our findings for a multi-service deployment by multiple actors. Results show important benefits for the case that considers the application of resource sharing in a multi-service, multi-actor scenario and the proposed model produces insights in the contributors to the cost per service and the unused amount of a resource. In addition, ex-ante insights in the cost flows per involved actor are obtained and the model can easily be extended to include revenue flows to evaluate the profitability per actor. As a consequence, the proposed model should be considered to support and stimulate upcoming multi-actor investment decisions for Internet-based multi-service offerings on-board trains with resource sharing
Toward Universal Broadband in Rural Alaska
The TERRA-Southwest project is extending broadband service to 65 communities in the
Bristol Bay, Bethel and Yukon-Kuskokwim regions. A stimulus project funded by a combination
of grants and loans from the Rural Utilities Service (RUS), TERRA-Southwest has installed a
middle-mile network using optical fiber and terrestrial microwave. Last-mile service will be
through fixed wireless or interconnection with local telephone networks.
The State of Alaska, through its designee Connect Alaska, also received federal stimulus
funding from the National Telecommunications and Information Administration (NTIA) for tasks
that include support for an Alaska Broadband Task Force âto both formalize a strategic broadband
plan for the state of Alaska and coordinate broadband activities across relevant agencies and
organizations.â
Thus, a study of the impact of the TERRA project in southwest Alaska is both relevant and
timely. This first phase provides baseline data on current access to and use of ICTs and Internet
connectivity in rural Alaska, and some insights about perceived benefits and potential barriers to
adoption of broadband. It is also intended to provide guidance to the State Broadband Task Force
in determining how the extension of broadband throughout the state could contribute to education,
social services, and economic activities that would enhance Alaskaâs future. Results of the
research could also be used proactively to develop strategies to encourage broadband adoption,
and to identify applications and support needed by users with limited ICT skills.Connect Alaska.

Exploring the democratic potential of online social networking: The scope and limitations of e-participation
Copyright © 2012 by the Association for Information Systems.The availability and promise of social networking technologies with their perceived open philosophy has increasingly inspired citizens around the world to participate in political activity on the Web. Recent examples range from opposing public policies, such as government funding cuts, to organizing revolutionary social movements, such as those in the Middle East and North Africa. Although online spaces create remarkable opportunities for various forms of political action, there are concerns over the power of existing institutions to control and even censor such interaction spaces. The objective of this article is to draw together different insights on the online engagement phenomenon, highlighting both its potential and limitations as a mechanism for fostering democratic debate and influencing policy making. We examine recent examples from Europe, the Middle East and Latin America. Finally, we summarize the implications of our work and outline directions for further research
