    The polaron-like nature of an electron coupled to phonons

    Full text link
    When an electron interacts with phonons, the electron can exhibit either free electron-like or polaron-like properties. The latter tends to occur for very strong coupling, and results in a phonon cloud accompanying the electron as it moves, thus raising its mass considerably. We summarize this behaviour for the Holstein model in one, two and three dimensions, and note that the crossover occurs for fairly low coupling strengths compared to those attributed to real materials exhibiting conventional superconductivity.Comment: 5 pages; contains a summary of single particle results for the Holstein mode

    Talking about Public Service Processes

    Part 5: Participation and eServicesInternational audienceMany discussions enforce the need to encourage Society’s involvement and participation in public issues. This paper moves towards the idea that the use of conversations about public services encourages closer ties between Society and Government. It presents a tool to support discussion and share of information about public service processes. The tool also enables the use of information obtained from conversations to identify service improvements

    Explaining History of eGovernment Implementation in Developing Countries: An Analytical Framework

    No full text
    Part 1: FoundationsInternational audienceThe paper proposes an analytical framework to explain history of e-Government implementation over a certain period of time in the context of developing countries. The framework is built upon General Systems Theory (GST) and Institutional Theory enriched with literature from organizational changes, and information systems/e-Government implementation. Three scenarios of implementation are proposed, each with its own departing worldview (i.e., mechanistic, organic, and colonial systems), isomorphic mechanism, implementation model, and possible impact
