  1. 1. Sensitivity Analysis of Untestable Assumptions in Causal Inference

    Författare :Mathias Lundin; Xavier de Luna; Maria Karlsson; Sune Karlsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Observational studies; semiparametric regression; unconfoundedness; Causal inference; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : This thesis contributes to the research field of causal inference, where the effect of a treatment on an outcome is of interest is concerned. Many such effects cannot be estimated through randomised experiments. For example, the effect of higher education on future income needs to be estimated using observational data. LÄS MER

  2. 2. Infinitely Demanding Entrepreneurship

    Författare :Mathias Karlsson; Martyna Sliwa; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; entrepreneurial practices; social change; ethics; politics; infinitely demanding; autonomous spaces; responsibility; faithless faith; humour; ethnography; Simon Critchley; philosophy; entrepreneurship; sustainability; entreprenörskap; samhällsförändring; etik; politik; oändligt krävande; autonoma utrymmen; ansvar; trolös tro; humor; etnografi; Simon Critchley; filosofi; hållbarhet; Ledarskap; entreprenörskap och organisation; Ledarskap; entreprenörskap och organisation;

    Sammanfattning : In both the study and the practice of entrepreneurship, the phenomenon of entrepreneurship is recurrently put forward as a key, or even the key, to resolving many of today’s social, ecological, and economic challenges. However, research shows that entrepreneurs who pursue social change risk overlooking or excluding certain worldviews, values, and ways of living. LÄS MER

  3. 3. On evaluation of organ damage in perinatal asphyxia : an experimental and clinical study

    Författare :Mathias Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Perinatal asphyxia; hypoxia-ischemia; hypothermia; pig; lactate dehydrogenase; aminotransferases;

    Sammanfattning : Leakage of intracellular enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) signalling multi organ dysfunction (MOD) is seen together with hypoxic ischemic encephalopathy (HIE) after perinatal asphyxia. Hypothermia (HT) can attenuate HIE following perinatal asphyxia and hypoxia-ischemia (HI) but the neuroprotective efficacy falls dramatically the longer the delay in initiating HT. LÄS MER

  4. 4. Mapping and annotating the mammalian body-wide protein-coding gene expression

    Författare :Max Karlsson; Mathias Uhlén; Linn Fagerberg; Julio Saez-Rodriguez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein; protein-coding; genes; annotation; atlas; scRNA-Seq; RNA-Seq; transcriptomics; proteomics; Biotechnology; Bioteknologi;

    Sammanfattning : A central aim of fundamental research is to create conditions necessary for fueling further research and innovation. Our understanding of basic biology is central for future developments of tools for diagnosing, monitoring, and treating disease. LÄS MER

  5. 5. Numerical and experimental study of confluent jets supply device with variable airflow

    Författare :Harald Andersson; Bahram Moshfegh; Mathias Cehlin; Fredrik Karlsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Air distribution system; Air supply device; Ventilation performance; Indoor air quality; Thermal comfort; Experimental study; Laser Doppler Anemometry LDA ; Computational fluid dynamics CFD ; Shear stress transport SST k – ω ; confluent jets; luftdistributionssystem; tilluftsdon; ventilationsprestanda; inomhusluftkvalitet; termisk komfort; experimentell studie; Laser-Doppler-anemometri LDA ; Computational fluid dynamics CFD ; turbulens model SST k – ω ; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : In recent years, application of confluent jets for design of ventilation supply devices has been studied. Similarly, numerus studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER
