    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Test construction; test validity; measurement; drivers; self-confidence;

    Abstract : The overall aim of this thesis was to develop and validate a self-report instrument for perceived driver competence. The thesis includes six papers and a summary. READ MORE

  5. 3. Criterion-referenced measurement for educational evaluation and selection

    Author : Christina Wikström; Widar Henriksson; Roger Murphy; Umeå universitet; []
    Keywords : Assessment; Competition; Criterion-referenced; Education; Evaluation; Grading; Grade inflation; Measurement; Selection; Validity; Beteendevetenskapliga mätningar; pedagogik; Education;

    Abstract : In recent years, Sweden has adopted a criterion-referenced grading system, where the grade outcome is used for several purposes, but foremost for educational evaluation on student- and school levels as well as for selection to higher education. This thesis investigates the consequences of using criterion-referenced measurement for both educational evaluation and selection purposes. READ MORE

  6. 4. Physics-based modelling and measurement of advanced manufacturing machinery’s positioning accuracy : Machine tools, industrial manipulators and their positioning accuracy

    Author : Nikolas Alexander Theissen; Andreas Archenti; Edward P. Morse; KTH; []

    Abstract : Advanced manufacturing machinery is a corner stone of essential industries of technologicallydeveloped societies. Their accuracy permits the production of complexproducts according to tight geometric dimensions and tolerances for high efficiency,interchangeability and sustainability. READ MORE

  7. 5. Measurement and prediction of outcome. Application in fusion surgery for chronic low backpain. The Swedish lumbar spine study

    Author : Olle Hägg; Göteborgs universitet; []
    Keywords : Chronic low back pain; clinical outcome; global assessment; measurement; ; minimal clinically important difference; pain drawing; physical disability; predictors.;

    Abstract : Background: Outcome of surgery for chronic low back pain should be documented ina standardised and reproducible fashion to establish evidence of its benefit. Measurement of outcome requires validated instruments, which have the ability to detect functionalchanges perceived as beneficial by the patient. READ MORE
