  1. 1. Tid till förfogande : Förändrad användning och fördelning av undervisningstid i grundskolans senare år?

    Författare :Mikaela Nyroos; Lisbeth Lundahl; Anders Lidström; Mikael Alexandersson; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; School autonomy; time allocation; time use; pupil influence; pupil individualisation; teacher work; change.; Pedgogical work; Pedagogiskt arbete;

    Sammanfattning : The Swedish education system has undergone decentralisation and deregulation since the late 1970s. The 1999 parliamentary resolution for a 5-year experiment of increased school autonomy in time allocation, was a late step in this development. LÄS MER

  2. 2. Challenges in Partially Automated Driving : A Human Factors Perspective

    Författare :Ignacio Solís Marcos; Katja Kircher; Alejandro Galvao; Tuomo Kujala; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Partial automation; human factors; event-related potentials; cognitive underload; task interference; additional task; automation experience; automation trust; Partial automation; mänskliga faktorer; Eventrelaterade potentialer; kognitiv underbelastning; arbetsstörningar; sidouppgift; automatiseringserfarenhet; automatiseringsförtroende;

    Sammanfattning : The technological development in recent years is currently reflected in the implementation of more and more advanced driver assistance systems (ADAS). A clear example is found in the automated driving systems being marketed today. LÄS MER

  3. 3. lac of Time : Transcription Factor Kinetics in Living Cells

    Författare :Petter Hammar; Johan Elf; Antoine van Oijen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription factor; lac operon; facilitated diffusion; single molecule imaging; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. LÄS MER

  4. 4. Workload transitions and stress : changes over time

    Författare :Erik Prytz; Mark Scerbo; USA VA Norfolk Old Dominion University Department of Psychology; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; human factors; workload transition; stress; workload;

    Sammanfattning : Workload transitions are situations where operators are suddenly confronted with levels of workload substantially different from previously established levels. Workload transitions may affect the operators' state of stress and coping behaviors but previous research has not conclusively demonstrated the nature of those. LÄS MER

  5. 5. Beyond the established risk factors of myocardial infarction : lifestyle factors and novel biomarkers

    Författare :Patrik Wennberg; Jan-Håkan Jansson; Mai-Lis Hellénius; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lifestyle factors; physical activity; commuting activity; leisure time physical activity; occupational physical activity; snuff use; haemostatic markers; inflammatory markers; myocardial infarction; epidemiology; primary prevention.; Family medicine; Allmänmedicin; Family Medicine; allmänmedicin;

    Sammanfattning : Age, male sex, hypertension, smoking, diabetes, dyslipidaemia, and obesity are considered as established risk factors for cardiovascular diseases. Several of these established cardiovascular risk factors are strongly influenced by lifestyle. LÄS MER
