  3. 2. Hastily Formed Networks och lokal egenmakt : En fallstudie utifrån implementeringen av en proaktiv katastrofledning i Indonesien

    Magister-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaper

    Författare :Camilla Andersson; [2014]
    Nyckelord :Organizational communication; Hastily Formed Network; proactive disaster management; local empowerment; bottom-up; micro commitment; learning organization.;

    Sammanfattning : The overall aim of this thesis is to, through a case study of a local disaster organization, study the prerequisites for building functional Hastily Formed Networks in disasters and also how HFN:s can be linked to a proactive disaster organization.The study looks upon HFN:s from the organizational, cognitive aspects of communication – not the network/information technology – and focus on the issue of local empowerment.
