    Sammanfattning : This thesis is a compilation of four papers in which mathematical reasoning is examined in various contexts, in which mathematics is an integral part. It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. LÄS MER

  4. 8. Plasticity of memory functioning : genetic predictors and brain changes

    Författare :Martin Bellander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human cognitive functions are not determined from birth, but are plastic and can be altered by environmental factors. The promising idea of a cognitive intervention that would improve memory functioning has attracted a lot of attention over the last decades. LÄS MER

  5. 9. Characteristics of the functional independence measure in patients with neurological disorders. Measurement through Rasch analysis

    Författare :Åsa Lundgren Nilsson; Göteborgs universitet; []
    Nyckelord :rehabilitation; assessment; measurement; stroke; traumatic brain injury; spinal cord injury; Rasch; item response theory;

    Sammanfattning : The Functional Independence Measure (FIMTM) is an internationally widely used outcome measure, measuring disability in terms of dependence or need of assistance. The aim of this study was to evaluate the structural characteristics of FIMTM using the Rasch model, with regard to scoring function, cross-cultural validity in Europe and cross-diagnostic validity within rehabilitation units in Scandinavia.

  7. 10. Psychometric aspects of obstructive sleep apnea syndrome

    Författare :Martin Ulander; Eva Svanborg; Anders Broström; Göran Kecklund; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Introduction: Obstructive sleep apnea (OSA) is a common chronic disorder consisting of episodes with impaired breathing due to obstruction of the upper airways. Treatment with Continuous Positive Airway Pressure (CPAP) is a potentially effective treatment, but adherence is low. Several potential factors affecting adherence, e.g. LÄS MER
