    Trust-Building through Social Media Communications in Disaster Management

    open4Social media provides a digital space – a meeting place, for different people, often representing one or more groups in a society. The use of this space during a disaster, especially where information needs are high and the availability of factually accurate and ethically sourced data is scarce, has increased substantially over the last 5-10 years. This paper attempts to address communication in social media and trust between the public and figures of authority during a natural disaster in order to suggest communication strategies that can enhance or reinforce trust between these bodies before, during and after a natural disaster.openM.

    Why Information Matters: A Foundation for Resilience

    Get PDF
    Embracing Change: The Critical Role of Information, a research project by the Internews' Center for Innovation & Learning, supported by the Rockefeller Foundation, combines Internews' longstanding effort to highlight the important role ofinformation with Rockefeller's groundbreaking work on resilience. The project focuses on three major aspects:- Building knowledge around the role of information in empowering communities to understand and adapt to different types of change: slow onset, long-term, and rapid onset / disruptive;- Identifying strategies and techniques for strengthening information ecosystems to support behavioral adaptation to disruptive change; and- Disseminating knowledge and principles to individuals, communities, the private sector, policymakers, and other partners so that they can incorporate healthy information ecosystems as a core element of their social resilience strategies

    Crisis Informatics: Perspectives of Trust – Is Social Media a Mixed Blessing?

    Get PDF
    This paper highlights one of the key concerns in the emerging area of crisis informatics: issues of trusted information in crises/disasters and how the unregulated nature of social media affects information creation and dissemination. Deciding which information providers to trust and what sources of information to trust in crises is critical as acting upon trusted information can shape and influence the nature of the crisis. Social media is a powerful tool for sharing information during crises and can be used to improve emergency management capabilities, however, it has the power to misinform and to hinder response efforts

    Economic and Workforce Development Task Force Report, August 2008

    The 2008 disasters devastated businesses, farms, homes, schools, non-profit institutions, entire communities, and people’s lives across the state of Iowa. The Rebuild Iowa Advisory Commission (RIAC) is charged by the Governor to guide the state’s recovery and reconstruction process. The Economic and Workforce Development Task Force is respectfully submitting this report to be included and considered in the deliberations of the RIAC. While economic and workforce development are two issues that are inextricably linked and critical to Iowa’s rebuilding strategies, each also requires extraordinary attention in determining what needs to be considered in the very immediate and longer-term recovery

    Named data networking for efficient IoT-based disaster management in a smart campus

    Disasters are uncertain occasions that can impose a drastic impact on human life and building infrastructures. Information and Communication Technology (ICT) plays a vital role in coping with such situations by enabling and integrating multiple technological resources to develop Disaster Management Systems (DMSs). In this context, a majority of the existing DMSs use networking architectures based upon the Internet Protocol (IP) focusing on location-dependent communications. However, IP-based communications face the limitations of inefficient bandwidth utilization, high processing, data security, and excessive memory intake. To address these issues, Named Data Networking (NDN) has emerged as a promising communication paradigm, which is based on the Information-Centric Networking (ICN) architecture. An NDN is among the self-organizing communication networks that reduces the complexity of networking systems in addition to provide content security. Given this, many NDN-based DMSs have been proposed. The problem with the existing NDN-based DMS is that they use a PULL-based mechanism that ultimately results in higher delay and more energy consumption. In order to cater for time-critical scenarios, emergence-driven network engineering communication and computation models are required. In this paper, a novel DMS is proposed, i.e., Named Data Networking Disaster Management (NDN-DM), where a producer forwards a fire alert message to neighbouring consumers. This makes the nodes converge according to the disaster situation in a more efficient and secure way. Furthermore, we consider a fire scenario in a university campus and mobile nodes in the campus collaborate with each other to manage the fire situation. The proposed framework has been mathematically modeled and formally proved using timed automata-based transition systems and a real-time model checker, respectively. Additionally, the evaluation of the proposed NDM-DM has been performed using NS2. The results prove that the proposed scheme has reduced the end-to-end delay up from 2% to 10% and minimized up to 20% energy consumption, as energy improved from 3% to 20% compared with a state-of-the-art NDN-based DMS
