  1. 1. Ledning av fusionsförlopp : en analys av bildandet av Ericsson Information Systems AB

    Författare :Göran Dahlgren; Per Witt; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Fusion är en ofta tillämpad strategi för att nå tillväxt och diversifiering. Omfattande erfarenheter av fusioner har samlats under decennier. Fusionsansträngningarna kröns likväl inte alltid med framgång. Misslyckad samordning i flera fusioner under senare år har förorsakat negativa ekonomiska utfall. LÄS MER

  3. 2. Work stress and overtime work - effects on cortisol, sleep, sleepiness and health

    Författare :Anna Dahlgren; Torbjörn Åkerstedt; Göran Kecklund; Mikael Sallinen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; work stress; overtime work; cortisol; sleep; sleepiness; fatigue; individual differences; within-subjects design; field study; Psychology; Psykologi;

    Sammanfattning : In Sweden the National Bureau of Statistics has reported an increase in stress-related disorders and sleep problems since the mid-1990’s. They also report that the number of hours of overtime worked has increased. LÄS MER

  4. 3. Fine-scale morphology and spectral characteristics of active aurora

    Författare :Hanna Dahlgren; Göran Marklund; Nickolay Ivchenko; Kari Kaila; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aurora; Space physics; Rymdfysik;

    Sammanfattning : Ground-based and in-situ observations of the aurora demonstrate an extreme richness in fine structure, with spatial scales down to tens of metres and time variations occurring on a fraction of a second. To further our understanding of the aurora, it is esssential to understand the mechanisms responsible for the small-scale structuring, since this is an intrinsic property of the auroral plasma.

  5. 4. Multi-spectral analysis of fine scale aurora

    Författare :Hanna Dahlgren; Göran Marklund; Nickolay Ivchenko; Fred Sigernes; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik; Optics; Optik;

    Sammanfattning : The Aurora Borealis is the visible manifestation of the complex plasma interaction between the solar wind and the Earth's magnetosphere and ionosphere. Ground based and in situ measurements demonstrate a prevalence of dynamic fine structure within auroral displays, with spatial scales down to tens of metres and time variations occurring on a fraction of a second.

  7. 5. An ounce of prevention is worth a pound of cure : preventive home visits among healthy seniors

    Författare :Klas-Göran Sahlén; Lars Lindholm; Lars Dahlgren; Carsten Hendriksen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preventive home visits; mortality; care utilisation; senior production; cost effectiveness; realist synthesis; Public health science; Folkhälsovetenskap; hälso- och sjukvårdsforskning; health services research;

    Sammanfattning : The aim of this thesis is to contribute to existing knowledge. If the knowledge is not useful in building society it has limited value. In order to be a tool for decision-makers, Preventive Home Visits (PHVs) are described and discussed according to a realist synthesis approach. LÄS MER
