    Författare :Maria Alm; Johan Hedrén; Lars Ingelstam; Eva Sandstedt; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; siting conflicts; sociotechnical systems; discourse analysis; space; place; practices; inclusion; exclusion; patterns of arguments; lokaliseringskonflikter; sociotekniska system; diskursanalys; plats; rum; praktiker; inneslutningar och utestängningar; mönster och utsagor; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Facility siting conflicts are increasing in our society. This is a study of a HVDC-link between Blekinge, Sweden and Slupsk, Poland called The SwePol Link. This link has transferred electricity between the two electricity systems since the year 2000 and the decision making process can be described as a struggle between conflicting interests. LÄS MER
