  2. 1. Essays on earnings formation, labor market dynamics, and taxation

    Author : Johan Holmberg; Thomas Aronsson; Gauthier Lanot; Johan Lundberg; Mette Ejrnæs; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Earnings dynamics; inequality; unemployment; social insurance; economic crises; taxation; Economics; nationalekonomi;

    Abstract : Chapter [I] analyses the dynamic properties of life-cycle earnings of men and women in Sweden by fitting a model to the covariance structure of earnings. We find that the financial crisis of 2008 did not have any major impact on the variability of earnings and that the upward trend in permanent earnings inequality observed in Sweden during the 1990s does not continue in the 2000s.

  4. 2. Galactic Structure Revealed by Space Astrometry

    Author : Johan Holmberg; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomi; cosmic chemistry; Galactic structure; Milky Way Galaxy; Galactic kinematics and dynamics; Galactic chemical evolution; moving groups; solar neighbourhood; dark matter; astrometry; Hipparcos; space research; Astronomy; rymdvetenskap; kosmisk kemi; Space technology; Rymdteknik; Fysicumarkivet A:2001:Holmberg;

    Abstract : This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically.

  5. 3. A Study of Propane and Propene Ammoxidation over the Mo-V-Nb-Te-Oxide System

    Author : Johan Holmberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; TEM; TPR; XPS; XRD; XANES; Chemical technology and engineering; SEM; FTIR; BET; TiO2; SiO2; Al2O3; supports; substitution; synthesis; Mo-V-Nb-Te-Ox catalysts; acrylonitrile; propene; Ammoxidation; propane; symbiosis;

    Abstract : The ammoxidation of propane is commonly regarded as being the future route for producing acrylonitrile, and the Mo-V-Nb-Te-oxide system studied here has thus far been seen as the most promising candidate for achieving this. Yields of up to 62% have been presented very elegantly in the patent literature. READ MORE

  6. 4. Dizziness and fear of falling: A behavioural and physiological approach to Phobic Postural Vertigo

    Abstract : Dizziness is a common problem and it often co-exists with anxiety. Level of anxiety is the best predictor of handicap for dizzy patients. There is diagnostic controversy and few treatment programs for such patients. READ MORE

  7. 5. Ephrins off the beaten path

    Author : Johan Holmberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The Orchestration of cell-cell interactions is crucial to the developing embryo and the adult organism. Intercellular communication is to a large extent controlled by signalling events downstream of receptor tyrosine kinases (RTKs). Ligands for RTKs are often soluble and confer long distance information to the receptor expressing cell. READ MORE
