  1. 11. Ämneskonstruktioner i ekonomismens tid : Om undervisning och styrmedel i modersmålsämnet i svenska och danska gymnasier

    Författare :Bengt Sjöstedt; Malmö högskola; []
    Nyckelord :subject constructions; governing system; governing document; subject of Swedish; subject of Danish; recontextualisation; frame factors; codes; determinants; subject didactics; Basil Bernstein; economism; new public management; trajectories; the teching and learning of Swedish; educational sciences;

    Sammanfattning : Under vilka villkor formar en dansklärare och en svensklärare sin pedagogiska gärning? Utifrån vilka ideal och organisatoriska förutsättningar möter de sina elever? Bengt Sjöstedt presenterar i denna doktorsavhandling i svenska med didaktisk inriktning sina svar på dessa frågor. Till grund för hans slutsatser ligger omfattande studier av undervisningen i skolämnena danska och svenska i gymnasiemiljöer i Danmark respektive Sverige. LÄS MER

  3. 12. Towards a sustainable automotive industry : experiences from the development of emission control systems

    Författare :David Bauner; Staffan Laestadius; Lee Schipper; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolutionary economics; environmental innovation; trajectories; co-evolution; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : From the mid-1970s and on, the contribution to air pollution of carbon monoxide, hydrocarbons and nitrogen oxides from gasoline passenger cars in the developed world has been reduced through co-evolution of regulation and commercial introduction of catalytic emission control technology, now part of hundreds of millions of cars, trucks and buses worldwide. This dissertation is a disaggregated study of the global introduction of catalytic emission control technology as a measure to reduce local air pollution. LÄS MER

  4. 13. Smoking cessation in Sweden - gender, pathways, and identity

    Författare :Tove Sohlberg; Jan Blomqvist; Pekka Hakkarainen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Smoking; smoking cessation; Sweden; gender; pathways; identity; socio-demographic background; socio-economic factors; trajectories; factor analyses; interviews; Sociology; sociologi;

    Sammanfattning : Research on smoking has to a great deal been conducted within a public health or a medical context, or focused on policy making. Fewer studies have taken their point of departure in a social sciences context, and still fewer have analysed why individuals start and cease to smoke, and how and why smoking patterns on an aggregate level change over time and vary between different population groups.

  5. 14. Physics-based Modelling for Aircraft Noise and Emission Predictions

    Författare :Evangelia Maria Thoma; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurements; trajectories.; emissions; interdependencies; FDR; turbofan engine; aircraft noise; physics-based modelling;

    Sammanfattning : Starting from semi-empirical noise source models for the aircraft and 4D trajectory computations, this work focuses on the environmental assessment of scenario studies regarding technology evaluation and procedural planning. Extensive work was performed on improving and validating the existing tools. LÄS MER

  7. 15. Evolutionary trajectories of Klebsiella pneumoniae : From experimental biofilm evolution to a hospital outbreak

    Författare :Greta Zaborskytė; Linus Sandegren; Vaughn S. Cooper; Uppsala universitet; []
    Nyckelord :Klebsiella pneumoniae; evolution; experimental evolution; biofilms; infection; bacterial pathogens; Mikrobiologi; Microbiology;

    Sammanfattning : Bacterial evolution is closely intertwined with our lives. As their hosts, we shape how bacteria evolve by imposing numerous selective pressures during the time bacteria spend in our bodies. As a result, they adapt in various ways to colonize us or infect us better. LÄS MER
