    Sammanfattning : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.

    Sammanfattning : Informations- och kommunikationstekniken har för många människor blivit en naturlig och viktig del i deras dagliga liv. Den öppnar för stora möjligheter men kan också innebära stora omställningar för människor. En återkommande fråga i den allmänna debatten är om alla människor i samhället kommer att kunna ta del av denna teknik. LÄS MER

  4. 3. Socialt entreprenörskap – informations- och kommunikationsteknologi för lokal handlingsgemenskap

    Författare :Claus Persson; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social learning; democracy; discussion; dialogue; virtual community; participative action; community of action; e-participation; e-democracy; ICT; social entrepreneurship; ethics;

    Sammanfattning : The theoretical findings of the thesis is composed of three parts, it consists of (i) a framework for social entrepreneurship, (ii) some pitfalls and success factors and (iii) a perspicuous design guide. These findings was a result of field research during a long time – more than 5 years, 2000-2005 – and the scientific purpose was to give a broad description and understanding of the research problem, which was: How should (i) social, (ii) pedagogical and (iii) technical components be arranged and aligned in a process to develop, uphold or vitalize a social and learning context by help of ICT-supported dialogue and discussion – e-democracy and e-participation – between ordinary participants/members and their representatives? The thesis describes a dialogue and discussion-based social entrepreneurship for the development and use of a similar like socio-technical ICT-artifact. LÄS MER
