  1. 16. Modeling and simulating inhibitory mechanisms in mental image reinterpretation : towards cooperative human-computer creativity

    Författare :Rita Kovordanyi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : With the accelerating development of computer and software technology, human-computer cooperation issues are becoming more and more centered on the human user's abilities and weaknesses. The cognitive characteristics of visual communication and reasoning, and how these affect the way users take advantage of the richness of visually represented information comprise one area which needs to be further explored within this context.

  3. 17. Mechanisms for leukocyte-mediated adjustment of endothelial barrier function

    Författare :Narinder Gautam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Inflammation; leukocyte extravasation; endothelial cells; vascular permeability; plasma leakage integrin signaling; heparin binding protein; contact phase; bradykinin.;

    Sammanfattning : Extravasation of polymorphonuclear leukocytes (PMN) and associated plasma exsudation are key events in the inflammatory process. The mechanism by which activated PMN may induce increased vascular permeability for macromolecules is not fully understood but crucially dependent on an intact leukocytic beta2 integrin (CD11/CD18) adhesion receptor function.

  4. 18. Genetic factors affecting pregnancy duration in humans

    Författare :Jonas Bacelis; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genomics; GWAS; Mendelian randomization; causal inference; preterm birth; pregnancy; gestation; height; text mining;

    Sammanfattning : This thesis investigates the mechanisms behind human pregnancy duration. Too short gestation is a direct cause of perinatal, neonatal, and infant mortality. Deviation from normal pregnancy length is also associated with a child's morbidity, even in the adulthood. LÄS MER

  5. 19. Models for Additive and Sufficient Cause Interaction

    Författare :Daniel Berglund; Timo Koski; Helga Westerlind; Ola Hössjer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Causal Inference; Sufficient Cause; Potential Outcomes; Counterfactual; Additive Interaction; Interaction; MFPO; ICI; Logistic Regression; Linear Odds; Public Health; Interventions; Probabilistic Potential Outcome; Matematisk statistik; Mathematical Statistics;

    Sammanfattning : The aim of this thesis is to develop and explore models in, and related to, the sufficient cause framework, and additive interaction. Additive interaction is closely connected with public health interventions and can be used to make inferences about the sufficient causes in order to find the mechanisms behind an outcome, for instance a disease.

  7. 20. Violent natural resource conflicts : From definitions to prevention

    Författare :Marie K. Schellens; Belyazid Salim; Stefano Manzoni; Silja Bára Ómarsdottir; Päivi Lujala; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural resource conflicts; natural resources; violent conflict; criticality; definition; predictive modelling; early warning; causal network; prevention; Physical Geography; naturgeografi;

    Sammanfattning : General scientific consensus is growing that natural resources play an important role in violent conflicts. Both scarcity and abundance contribute to violent conflict, depending on the socio-economic and political conditions at play. LÄS MER
