1. 16. Case-crossover studies of the triggering of disease : myocardial infarction and Ménières disease

   Författare :Jette Möller; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Myocardial infarction; Ménières disease; case-crossover; trigger; physical exertion; anger; sexual activity; life events; misclassification; recall bias;

   Sammanfattning : The general objective of this thesis is to contribute to understanding of the aetiology of myocardial infarction. It focuses on identification and risk-quantification of the factors acting late in the causal chain towards manifest myocardial infarction, so-called triggers, by using the case-crossover design.

3. 17. Modelling the Structural Dynamics of Business Networks : Two Agent-based Models of Supply Networks

   Författare :Sara Shahin Moghadam; Frans Prenkert; Franziska Klügl; Magnus Hansson; Davide Secchi; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business networks; dynamics; Agent-based modelling; structural change; responses; interactions; complex adaptive systems;

   Sammanfattning : This thesis aims at describing and analysing the structural changes of business networks that emerge as a result of change triggers. Despite previous studies, our understanding of the evolution of the network structure and its influencing factors is still limited. LÄS MER

4. 18. Psychological momentum in handball

5. 19. Regulatory mechanisms of amino acid-induced signaling in Saccharomyces cerevisiae

   Författare :Deike J. Omnus; Per O. Ljungdahl; Claudio De Virgilio; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; regulatory mechanisms; nutrient sensing; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

   Sammanfattning : This thesis describes studies aimed at elucidating the molecular mechanisms that regulate the SPS (Ssy1-Ptr3-Ssy5) signal transduction pathway in the yeast Saccharomyces cerevisiae. This pathway is induced by extracellular amino acids and facilitates their uptake. LÄS MER

7. 20. Violence among mentally disordered offenders : risk and protective factors

   Författare :Ulrika Haggård-Grann; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Violence is one of the leading causes of unnatural deaths, and the consequences of violence for victims, victims families, offenders, and society at large involve extensive suffering and monetary costs. Improving strategies to prevent and reduce violence is of great importance, and refining techniques for risk assessments in forensic and correctional settings is assumed to be one way of doing so.
