1. 1. The Governance of Missing Asylum-Seekers in Sweden : Managing "Missingness" Through Different Technologies of Power

   Författare :Anna Hammarstedt; Mark Rhinard; Tom Lundborg; Charlotte Wagnsson; Mark B. Salter; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; missingness; Swedish asylum regime; asylum-seekers; Foucault; technologies of power; internationella relationer; International Relations;

   Sammanfattning : For a highly controlled and comprehensive welfare state such as Sweden, one can assume that incorporating populations into a system of bureaucratic management (and keeping them there) is paramount to its overall functioning. Either subjects are incorporated into the system and thereby managed, or subjects are expelled from the system and no longer managed. LÄS MER

3. 2. Biomarkers and psychological stress in amyotrophic lateral sclerosis

   Författare :Ulf Kläppe; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a complex and progressive neurological disorder that causes a wide range of symptoms, including muscle weakness, mobility impairment, and marked functional decline. Unfortunately, there is currently no known cure for ALS, and median survival time is between two to four years, although this varies considerably between individuals. LÄS MER

4. 3. Uncertainty intervals and sensitivity analysis for missing data

   Författare :Minna Genbäck; Xavier de Luna; Elena Stanghellini; Arvid Sjölander; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; missing data; missing not at random; non-ignorable; set identification; uncertainty intervals; sensitivity analysis; self reported health; average causal effect; average causal effect on the treated; mixed-effects models; Statistics; statistik;

   Sammanfattning : In this thesis we develop methods for dealing with missing data in a univariate response variable when estimating regression parameters. Missing outcome data is a problem in a number of applications, one of which is follow-up studies. LÄS MER

5. 4. Interpretable machine learning models for predicting with missing values

   Författare :Lena Stempfle; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; missing values; Machine learning; healthcare; interpretable machine learning;

   Sammanfattning : Machine learning models are often used in situations where model inputs are missing either during training or at the time of prediction. If missing values are not handled appropriately, they can lead to increased bias or to models that are not applicable in practice without imputing the values of the unobserved variables. LÄS MER

7. 5. Computational statistical methods for genotyping biallelic DNA markers from pooled experiments

   Författare :Camille Clouard; Carl Nettelblad; Lars Rönnegård; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The information conveyed by genetic markers such as Single Nucleotide Polymorphisms (SNPs) has been widely used in biomedical research for studying human diseases, but also increasingly in agriculture by plant and animal breeders for selection purposes. Specific identified markers can act as a genetic signature that is correlated to certain characteristics in a living organism, e. LÄS MER
