    Nyckelord :Data mining; resilience measure; attribute selection; error rate; classification; Datautvinning; resiliensmått; attributval; simulering; felfrekvens; klassificering;

    Sammanfattning : This study uses a simulation to gather data regarding a payment disruption. The simulation is part of a project called CCRAAAFFFTING, which examines what happens to a society when a payment disruption occurs. LÄS MER

  7. 5. Att gestalta en mördare : En studie om mediernas gestaltning av Thomas Quick

    Kandidat-uppsats, Karlstads universitet/Institutionen för geografi, medier och kommunikation

    Författare :Viktoria Nilsson; Emma Båld; [2015]
    Nyckelord :mediepåverkan; attribut; Thomas Quick; mediegestaltning; medier och brott;

    Sammanfattning : Media has a big actuating power over the public opinion. The image of reality that media choose to reproduce will affect the recipient view of reality. The case about Thomas Quick and its associated news coverage has been used as an example to illustrate the problematization regarding media imag-es and media framing attempt. LÄS MER
