    Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER

  2. 2. Prometheus at the wheel : Representations of road transport informatics

    Författare :Oskar Juhlin; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnography; engineering; representational practice; testing; technical demonstration; constructivism; road transport informatics; intelligent transportation systems; situated practice; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The dissertation deals with the challenge of developing information technology for road transport, a field often referred to as Road Transport Informatics. Oskar Juhlin studies in particular how engineers cope with the contingent and social aspects of the design process and of road use. LÄS MER

  3. 3. Mainstreaming passive houses : A study of energy efficient residential buildings in Sweden

    Författare :Johan Niskanen; Harald Rohracher; Ann-Sofie Kall; Christian Koch; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; passive house; mainstreaming; sustainable innovation; technology deployment; socio-technical transition; passivhus; mainstreaming; hållbara innovationer; teknikspridning; socio-teknisk omställning;

    Sammanfattning : The passive house concept has become increasingly popular in the building sector in the lost twenty years ond is deemed to ploy on important role in aligning the housing sector with climate and environmental policy objectives. However, for such buildings to ploy this port they need to be more widespread, more common and more accepted by mainstream actors and institutions. LÄS MER

  4. 4. Actor roles, knowledge types and the role of patenting for progressing sustainable technologies: A case study of demonstration projects

    Författare :Sofia Nordqvist; Johan Frishammar; Hans Hellsmark; Luleå tekniska universitet; []

    Sammanfattning : The transition towards a bioeconomy is one of the greatest challenges of our times, and dependent upon radical innovations and the replacement of fossil-based technologies with clean and more sustainable ones. This is however not done in a jiffy since key underlying process technologies are underdeveloped and also contradict with the prevailing socio-technical regime. LÄS MER

  5. 5. Preparing for takeoff : Analyzing the development of electric road systems from a business model perspective

    Författare :Stefan Tongur; Mats Engwall; Fredrik Lagergren; Henrik Blomgren; Lars Coenen; KTH; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Electric road systems ERS ; business models; socio-technical change; sustainable transition; strategic niche management; Industrial Economics and Management; Industriell ekonomi och organisation;

    Sammanfattning : Electric road systems (ERS) are road transportation systems based on technologies that support electric power transfer from roads to vehicles in motion. Transition toward alternative technologies, such as ERS, is necessary in order to achieve the sustainability goals in road transportation. LÄS MER
