  1. 1. Derivation and BRST Quantization of Models for Spinning Relativistic Particles

    Författare :Ulf Mårtensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with the construction of models for spinning relativistic particles and their covariant quantization within a BRST framework. In the first part the ideas and methods which constitute the background to the papers are reviewed, and a summary of the main results obtained therein is given. The second part consists of the papers. LÄS MER

  4. 3. Drömmar om något bättre : Om managementmodeller, mätningar och människor

    Författare :Maria Mårtensson; Ulf Johanson; Anders W Johansson; Magnus Söderström; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; managementmodeller; mätning; människor; balanserat styrkort; intellektuellt kapital; knowledge management; politisk aritmetik; Business studies; Företagsekonomi; Business administration; Företagsekonomi; Industriell ekonomi och organisation;

    Sammanfattning : For several years I have, from a management control perspective, followed the development and application of several popular management models, for example, the knowledge management, balanced scorecard, and intellectual capital models. This thesis, comprising four papers and an extended covering paper, contributes to the management control field by discussing and problematizing management models and how they describe humans by means of measurement.

  5. 4. Hope and life-struggle : patients' experiences with Transcatheter Aortic Valve Implantation

    Författare :Karin Olsson; Åsa Hörnsten; Ulf Näslund; Jan Mårtensson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; transcatheter aortic valve implantation; experiences; coping; decision-making; health-related quality of life; symptoms; function; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : The overall aim of this thesis is to explore experiences and self-reported outcomes from Transcatheter Aortic Valve Implantation, TAVI, among people with severe aortic stenosis. The thesis includes four studies. Study I-II are based on interviews performed the day before TAVI and Qualitative Concept Analysis was used for analysis. LÄS MER
