   Sammanfattning : Fatigue is an individual and subjective sensation interfering with daily living for patients with several chronic conditions. Systemic lupus erythematosus (SLE) is characterized by inflammation in different organs combined with immunological abnormalities. LÄS MER

3. 2. Extinctions and Ecosystem Stability

   Författare :Susanne Pettersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; structural stability; ecosystems; interaction structure; Generalised Lotka-Volterra; complexity; local stability; dynamical systems; stability;

   Sammanfattning : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. LÄS MER

   Sammanfattning : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. LÄS MER

5. 4. Powered mobility device use: participation and accessibility

   Författare :Cecilia Pettersson; Susanne Iwarsson; Åse Brandt; Eva Månsson Lexell; Aktivt och hälsosamt åldrande; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autonomy; environmental barrier; focus groups; housing adaptation; housing enabler; independence; mobility; mobility-related participation; occupational therapy; powered scooter; powered wheelchair; spinal cord injury; Occupational therapy;

   Sammanfattning : This thesis elucidates the use of powered mobility devices in a Swedish context. The overall aim was to increase and deepen the knowledge on powered mobility device use in relation to participation and accessibility in different environments and among different user groups, with a specific focus on independence and autonomy.

7. 5. Multiple Kernel Imputation : A Locally Balanced Real Donor Method

   Författare :Nicklas Pettersson; Daniel Thorburn; Susanne Rässler; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian Bootstrap; Boundary Effects; External Information; Kernel estimation features; Local Balancing; Pólya Sampling; statistik; Statistics;

   Sammanfattning : We present an algorithm for imputation of incomplete datasets based on Bayesian exchangeability through Pólya sampling. Each (donee) unit with a missing value is imputed multiple times by observed (real) values on units from a donor pool. The donor pools are constructed using auxiliary variables. LÄS MER
