  2. 11. Changing Swedish sickness insurance : Policies, institutions and outcomes

    Author : Nadja Grees; Joakim Palme; Sven Oskarsson; Axel West Pedersen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sickness insurance; disability pension; Sweden; occupational welfare; policy change; stratification; social policy analysis; non-take-up; Statskunskap; Political Science;

    Abstract : The aim of this thesis is to contribute to welfare state theorising by analysing changing risk protection in Swedish sickness insurance and demonstrate how the understanding of such, and its implications, can be enhanced by strategic methodological choices. When analysing formal policy change in the compulsory sickness insurance system, it is concluded that the Swedish system fulfils almost every aspect of a so called social democratic welfare state, and no institutional shift can be discerned over time.

  4. 12. Diel vertical migration in marine dinoflagellates

    Author : Therese Jephson; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Key words: diel vertical migration; DVM; dinoflagellates; stratification; halocline; thermocline; behavior diel vertical migration; behavior;

    Abstract : Increasing precipitation and surface water temperature due to global change may strengthen stratification in coastal regions, which could influence the behavior of dinoflagellate diel vertical migration (DVM). DVM is a behavioral mechanism by which dinoflagellates can access photosynthetically active radiation near the surface, and nutrients at depth. READ MORE

  5. 13. Characterising turbulent ship wakes from an environmental impact perspective

    Author : Amanda Nylund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; stratification; ship wake; turbulence; methane emission; shipping; energy pollution; environmental impact;

    Abstract : The world’s oceans, especially coastal areas, are intensively trafficked by ships. All these ships exert pressure on the marine environment, through emission to the atmosphere, discharges of pollutants to the water, and physical disturbance through energy input. Of these impacts, energy pollution from shipping has received the least attention. READ MORE

  6. 14. Nonparametric tests for comparing two treatments by using ordinal data

    Author : Helen Wahlström; Elisabeth Svensson; Jan Lanke; Sture Holm; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; change; clinical trial; Monte Carlo; ordered categorical data; paired data; permutation test; Pitman efficiency; power; stratification; ties; visual analogue scale; Wilcoxon-Mann-Whitney statistic; statistik; Statistics; Statistik; Statistics; Statistik;

    Abstract : This thesis concerns four nonparametric tests for comparing two treatments in a randomized controlled clinical trial when the main response variable generates discrete or continuous ordinal data and measurements are made at baseline and follow-up. In the Wilcoxon-Mann-Whitney test (WMW) the baseline values are not taken into account at all, but in the other three tests both baseline and follow-up values are used. READ MORE
