    Sammanfattning : Paper [I] studies equality of opportunity in Sweden. The distinction between circumstances that constrain an individual’s opportunities and the individual choices also affecting a particular outcome is the main idea of theories of equality of opportunity. LÄS MER

  2. 2. Specifying the Heterogeneity in Children with ADHD : Symptom Domains, Neuropsychological Processes, and Comorbidity

    Författare :Cecilia Wåhlstedt; Gunilla Bohlin; Björn Lyxell; Uppsala universitet; []
    Nyckelord :ADHD; Heterogeneity; Hyperactivity Impulsivity; Inattention; Neuropsychological Pathways; Comorbidity; Psychology; Psykologi;

    Sammanfattning : Heterogeneity in children with Attention Deficit Hyperactivity Disorder (ADHD) symptoms is a well-known phenomenon. Empirically, this heterogeneity is evident in at least three different respects: expression of the two ADHD symptom domains (hyperactivity/impulsivity and inattention), neuropsychological impairments, and comorbid behavior problems.

    Sammanfattning : Cellular resistance to chemotherapy is a major cause of treatment failure in acute myeloid leukaemia (AML) and still the majority of the patients die from their disease. Drug resistance 1s multifactorial, the most studied mechanism being multidrug resistance (MDR), mediated by the P-glycoprotein (Pgp). LÄS MER

  4. 4. Aspects of heterogeneity : effects of clear-cutting and post-harvest extraction of bioenergy on plants in boreal forests

    Författare :Marcus Åström; Christer Nilsson; Katherine Frego; Umeå universitet; []
    Nyckelord :aspect; clear-cutting; disturbance; habitat quality; liverworts; logging residues; mosses; resilience; slash; slope; topography;

    Sammanfattning : Abstract. The objectives of this thesis are to evaluate (1) the influence of slope aspect on boreal plant responses to clear-cutting and (2) the effects of post-harvest extraction of bioenergy (logging residues or slash) on plant composition, richness and performance in clear-cuts.
