  1. 11. Preference Effects in the Treatment of Panic Disorder

    Författare :Martin Svensson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preference effects; Doubly randomised controlled preference trial; ; Panic disorder; Cognitive behavioural therapy; Psychodynamic therapy;

    Sammanfattning : Patient preferences have drawn considerable attention as a potential moderator of treatment outcome. The Doubly Randomised Controlled Preference Trial (DRCPT) in which patients are randomised to a choice between two or more treatments or random assignment to one of these same treatments is considered one of the most rigorous tests of the effects of patient preferences on outcomes.

  3. 12. Statistical Physics of DNA: Melting and Confinement Effects

    Författare :Michaela Reiter-Schad; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; DNA melting; DNA confinement; random walk; Fysicumarkivet A:2015:Reiter-Scad;

    Sammanfattning : Investigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. LÄS MER

  4. 13. Semiparametric survival models for routine register data

    Författare :Frank Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Survival; transformation; clustered; likelihood; random effects; case-cohort; routine register; semiparametric; clustered;

    Sammanfattning : Routine registers offer researchers opportunities to carry out studies of covariate effects on lifetimes of rare diseases otherwise infeasible because of the large cohorts required. Familial relationships necessary for analysis of environmental or genetic factors can be identified by record linking. LÄS MER

  5. 14. Essays on Immigrants' Economic Integration

    Författare :Kerem Tezic; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Second-generation immigrants; educational attainments; early labour-market experiences; competing-risks; graduate employment; calibration; first-generation immigrants; sample-selection in panel data; random effects.;

    Sammanfattning : This thesis consists of five papers, related to each other in terms of study-sample, study-subject or methods used. The first paper is concerned with second-generation immigrants' educational attainments, using the Longitudinal Individual Data-set (LINDA), which gave us the possibility to examine changes over time, from ages 16-17 to 21-22 and to compare second-generation immigrants with a randomly-chosen matched control-group of native Swedes.

  7. 15. First-principles investigations of ordering in binary alloys

    Författare :Moshiour Rahaman; Andrei Ruban; Staunton Julie; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ordering; random; alloys;

    Sammanfattning : The aim of the thesis is to study ordering in binary alloys on the basis of first-principles or {\it ab-initio} techniques employing density functional theory (DFT). The ordering phenomena of materials are of crucial importance for technological applications. LÄS MER
