  1. 6. Exploring and modeling response process data from PISA : inferences related to motivation and problem-solving

    Författare :Erik Lundgren; Hanna Eklöf; Inga Laukaityte; Per-Erik Lyrén; Samuel Greiff; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; response processes; large-scale assessments; motivation; problem-solving; computational modeling; Bayesian modeling; didactics of educational measurement; beteendevetenskapliga mätningar;

    Sammanfattning : This thesis explores and models response process data from large-scale assessments, focusing on test-taking motivation, problem-solving strategies, and questionnaire response validity. It consists of four studies, all using data from PISA (Programme for International Student Assessment) data. LÄS MER

  3. 7. Outcome in psychiatric outpatient services : reliability, validity and outcome based on routine assessments with the GAF scale

    Författare :Per Söderberg; Stefan Tungström; Bengt-Åke Armelius; Odd E. Havik; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; reliability; validity; outcome; effectiveness; clinical; significance; GAF scale; DSM-IV; outpatients; psychiatry; dose response; services; Psychology; Psykologi;

    Sammanfattning : The general aim of the studies presented in this thesis is to investigate the possibility of using clinical data to measure outcomes in psychiatric outpatient services. The specific aims are to investigate whether routine clinical assessments and ratings are reliable and have adequate validity, and then to use these data to calculate treatment outcomes and explore factors that affect these outcomes.

  4. 8. Cross-scale mechanisms and adaptation strategies in Small-Scale Fisheries

    Författare :Blanca González-Mon; Maja Schlüter; Beth Fulton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small-Scale fisheries; networks; agent-based modelling; trade; migration; mobility; diversification; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Small-Scale Fisheries (SSF) are increasingly facing shocks and changes that affect their capacity to provide food and maintain the livelihoods of millions of people who depend on fishing activities. At the same time, SSF influence and are influenced by interactions across scales, where interdependencies between different places are increasingly evident. LÄS MER

  5. 9. End-Shield Bridges for High-Speed Railway : Full scale dynamic testing and numerical simulations

    Författare :Hesham Elgazzar; Jean-Marc Battini; Mahir Ülker-Kaustell; Morgan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed railway; end-shield bridges; structural dynamics; soil structure interaction; full scale bridge testing; controlled forced excitation; hydraulic bridge exciter; frequency response function; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.

  7. 10. Effects of high sugar concentrations in production scale bioreactor : a scale-down study of s. cervisiae

    Författare :Stefan George; KTH; []
    Nyckelord :;

    Sammanfattning : Substrate concentration gradients exist in large-scalebioreactors, due to a combination of insufficient mass transferand mixing, and microbial activities. Zones with high substrateconcentration may arise close to a feed point. It is largelyunknown to what extent these gradients influence themicroorganisms and what the microbial response might be.
