  3. 2. Tartrate resistant acid phosphatase in the immune and nervous system : distribution and pathophysiological implications

    Författare :Pernilla Lång; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tartrate resistant acid phosphatase (TRAP) belongs to the family of purple acid phosphatases (PAP). It is a glycoprotein synthesized as a monomer with low enzyme activity containing a redox active diiron centre in the active site. Post-translational proteolytic processing of this monomer into a dimeric protein increases the enzyme activity. LÄS MER

  5. 4. Short- and Long-Term Influences of Education, Health Indicators, and Crime on Labor Market Outcomes : Five Essays in Empirical Labor Economics

    Författare :Elisabeth Lång; Ali M. Ahmed; Judy Rich; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; health indicators; crime; labor market outcomes; family background; twins; field experiments;

    Sammanfattning : The objective of this thesis is to improve the understanding of how several individual characteristics, namely education (years of schooling), health indicators (height, weight, smoking, alcohol consumption, and exercise), criminal behavior, and crime victimization, influence labor market outcomes in the short and long run. The first part of the thesis consists of three studies in which I adopt a within-twin-pair difference approach to analyze how education, health indicators, and earnings are associated with each other over the life cycle.

  7. 5. Income and Fuel Price Elasticities of Car Use

    Författare :Carl Berry; Maria Börjesson; Elisabeth Lång; Rob Hart; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Income elasticity; Fuel price elasticity; Car use; Car ownership; Registry data; Discrete-continuous model;

    Sammanfattning : Understanding how car travel and ownership respond to income and fuel prices, and how that response varies between households is crucial for car use policies and forecasts. This thesis, consisting of two papers, aims to investigate this by estimating the intemporal income and fuel price elasticities of car use using micro registry panel data on all Swedish households from 1998 to 2018.
