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

    University dissertation from Karlstad : Karlstads universitet

    Author : Florencia Enghel; Miyase Christensen; Karin Wilkins; Robin Mansell; [2014]
    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.

  5. 5. Modeling the effects of knots in Structural Timber

    University dissertation from Structural Engineering, Lund University

    Author : Christina Foley; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; Byggnadsteknik; Building construction; three-dimensional fiber paradigm; fiber deviation; knots; annual growth layer; material matrix; knot bump; structural timber; load carrying capacity; Materiallära; critical knot; knot distance ratio; local principal material directions; stiffness; materialteknik;

    Abstract : The main purpose of the pursued research is to increase knowledge of the effects of knots in structural timber so that characteristics of weaker timber may be determined and applied to improve current grading techniques. In the process, a three-dimensional fiber paradigm was established, which describes variations of local principle material axes in timber containing knots. READ MORE
