  1. 1. Modeling Driver Behavior : A Control Theory Based Approach

    Författare :Katja Vogel; Lars Åberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the project, which led to this thesis, was to suggest a micro-level driver behavior model, which would allow estimating the effects of safety measures on road traffic safety. The empirical research on driver behavior should be conducted in urban areas, because they are much less explored than rural areas, even though most non-fatal accidents occur in urban areas. LÄS MER

  3. 2. International and export behavior of firms : a critical review and empirical assessment

    Författare :Dafnis Coudounaris; Arthur Money; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industriell marknadsföring; Industrial Marketing;

    Sammanfattning : The current thesis examines exporting as a leading discipline in International Business and sheds light into various exporting issues which have not been thoroughly investigated in the past. The thesis is divided into two parts. The first part includes two studies based on literature review, specifically on International Management and Exporting. LÄS MER

  4. 3. Critical Phenomena and Exchange Coupling in Magnetic Heterostructures

    Författare :Martina Ahlberg; Gabriella Andersson; Björgvin Hjörvarsson; Steve Bramwell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phase transitions; critical behavior; 2D XY model; MOKE; magnetic thin films and superlattices; amorphous multilayers; magnetic proximity effects; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : The continuous phase transition in thin magnetic films and superlattices has been studied using the magneto-optical Kerr effect (MOKE) and polarized neutron scattering (PNR).  It has been shown that the critical behavior of amorphous thin films belonging to the 2D XY universality class can be described within the same theory as crystalline sample.

  5. 4. Overall Accessibility of Public Transport for Older Adults

    Författare :Catherine Sundling; Mats E. Nilsson; Birgitta Berglund; Leslie R. Pendrill; Ragne Emardson; Bo Edvardsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; older persons; critical incidents; critical reactions; travel behavior; accessibility; functional limitation; functional ability; barrier; facilitator; public transport; railway travel; Psychology; psykologi;

    Sammanfattning : This thesis is based on four studies that explore accessibility for older adults during whole trips by public transport. The overall goal was to gain knowledge of the interrelationships among key variables and to develop a conceptual model of the overall accessibility of public transport. LÄS MER

  7. 5. Individual differences in behavior, neurochemistry and pharmacology associated with voluntary alcohol intake

    Författare :Shima Momeni; Erika Roman; Bo Söderpalm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intermittent access; multivariate concentric square field; open field; risk assessment; risk taking; individual difference; behavior; strain variation; endogenous opioid system; naltrexone; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Alcohol use disorder is a worldwide public health problem and is a disorder with substantial individual variation. There are suggested links between various behavioral traits, comorbid psychiatric diseases and excessive alcohol consumption. LÄS MER
