  1. 16. Fearful attention : Investigating event-related potentials in spider phobia

    Författare :Joakim Norberg; Stefan Wiens; Jonas Persson; Harald Schupp; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; phobia; event-related potential; Psychology; psykologi;

    Sammanfattning : Previous studies showed that emotional pictures capture attention. Further, this effect was decreased by manipulating spatial attention. In contrast, studies produced mixed findings for effects of perceptual load on attention to emotional pictures. Emotional pictures can be phobic or nonphobic. LÄS MER

    Sammanfattning : Childhood obesity is a threat to public health worldwide. In Sweden around 15% of children 5-19 years of age are overweight and 3-4 % have obesity. Early prevention is crucial as are effective treatments for children and adolescents who have already developed obesity. LÄS MER

  4. 18. Topics in Complex Analysis and Operator Theory I. The shift operator on spaces of vector-valued analytic functions II. Fatou-type theorems for general approximate identities III. Preduals of Q_p-spaces

    Författare :Marcus Carlsson; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Qp-spaces; Non-tangential limits; Shift operator; Mathematics; Matematik;

    Sammanfattning : This thesis consists of six articles on three different subjects in the area of complex analysis, operator theory and harmonic analysis. Part I - "The Shift Operator on Spaces of Vector-valued Analytic Functions" consists of three closely connected articles that investigate certain operators in the Cowen-Douglas class with spectrum D - the unit disc, or equivalently, the shift operator M_z (multiplication by $z$) on Hilbert spaces of vector-valued analytic functions on D.
