  1. 11. Pension Eligibility and Retirement Behavior : Did the 1979 Swedish pension reform affect immigrant retirement behavior?

    Författare :Mikael Ohlson; Mårten Palme; Olof Åslund; Växjö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Retirement; Disability; Immigrants; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : We examine the effects of changed eligibility rules to disability pension by the 1979 Swedish pension reform on immigrant retirement behavior. The reform made disability pension in the form of basic pension available to a wider group of immigrants. LÄS MER

  3. 12. Studies in Estimation of Patterned Covariance Matrices

    Författare :Martin Ohlson; Timo Koski; Dietrich von Rosen; Augustyn Markiewicz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Many testing, estimation and confidence interval procedures discussed in the multivariate statistical literature are based on the assumption that the observation vectors are independent and normally distributed. The main reason for this is that often sets of multivariate observations are, at least approximately, normally distributed. LÄS MER

  4. 13. Essays on Immigrants and Institutional Change in Sweden

    Författare :Mikael Ohlson; Mårten Palme; Per Lundborg; Växjö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; retirement; disability; self-selection; immigrants; wage inequalities; wage discrimination; product market deregulation; competition; naturalization; citizenship; ; economic impact; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of three self-contained essays about immigrants’ experiences in Sweden. They all focus on the interaction between institutional settings and effects on immigrants’ economic conditions. LÄS MER

  5. 14. The use of evolutionary information in protein alignments and homology identification

    Författare :Tomas Ohlson; Arne Elofsson; Sven Hovmöller; Geoffrey J. Barton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein alignment homology sequence profile; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : For the vast majority of proteins no experimental information about the three-dimensional structure is known, but only its sequence. Therefore, the easiest way to obtain some understanding of the structure and function of these proteins is by relating them to well studied proteins. This can be done by searching for homologous proteins. LÄS MER

  7. 15. Characterization of Carbon Oxidation Kinetics for Particulate Matter Reduction Technologies

    Författare :Carolin Ohlson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogeneous catalysis; Carbon – catalyst interaction; Soot oxidation; Particulate filter; Carbon oxidation; Global kinetics; Regeneration; Particulate matter oxidation; DPF;

    Sammanfattning : Transport related emissions of particulate matter (PM) represent a significant health risk and are therefore strictly regulated in most developed countries. An efficient technique to reduce emissions of combustion particles is to capture the particles in a filter, which must be subsequently regenerated by oxidation of the carbonaceous fraction of the PM.
