  2. 2. Video letters, mediation and (proper) distance : A qualitative study of international development communication in practice

    Author : Florencia Enghel; Miyase Christensen; Karin Wilkins; Robin Mansell; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; development communication; mediation; proper distance; international; video letters; Media and Communication Studies; Medie- och kommunikationsvetenskap;

    Abstract : This study scrutinizes the trajectory of an international development communication intervention aimed at mediating, rendering public and mobilizing processes of reconnection among estranged citizens across the former Yugoslavia. The intervention, which took place between 2000 and 2005 in the wider context of post-conflict international development assistance and peacebuilding operations in the region, was known as the Videoletters project.
