  1. 1. Knowledge, Product Differentiation and Trade

    Författare :Sara Johansson; Åke Andersson; Börje Johansson; Volker Nitsch; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accessibility; Export; Human Capital; Innovation; Knowledge; Product Differentiation; Product Quality; Regional trade; Economics; Nationalekonomi;

    Sammanfattning : The purpose of this thesis is to analyze the influence of knowledge on the export performance of firms in different regions. More specifically, this study focuses on the impact of knowledge on the structure of regional export flows, in terms of horizontal and vertical product differentiation, as well as the geographical distribution of export flows.

    Sammanfattning : Parkinson's disease (PD) is the second most common neurodegenerative disease and affects 2% of the population over 65 years of age. The disease is characterized by the progressive loss of dopaminergic neurons. Over time, symptoms increase and, in particular, lead to a dramatic slowness of movements. LÄS MER

  3. 3. School choice, space and the geography of marketization- Analyses of educational restructuring in upper secondary education in Sweden

    Författare :Anna Maria Fjellman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; school choice; school market; marketization; space; equity; quasi-market; differentiation; spatial justice;

    Sammanfattning : The main aim of the dissertation is to investigate, analyze and create a research-based understanding of the spatialities of the Swedish school choice in upper secondary education using a socio-spatial framework. The dissertation is comprised of three empirical studies based on six cohorts of register data from The Gothenburg Longitudinal Database. LÄS MER

  4. 4. Evolutionary Processes and Spatial Genetic Variation in Euphrasia stricta on the Baltic Island of Gotland

    Författare :Anna-Karin Kolseth; Brita Svensson; Mikael Lönn; Joop Ouborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; genetic differentiation; regional processes; conservation genetics; AFLP; microsatellites; gene flow; local adaptation; shape analysis; Ekologi;

    Sammanfattning : The identification of processes governing genetic structure at different spatial scales remains a major challenge in evolutionary biology and is of considerable applied interest in conservation biology. In Euphrasia stricta five varieties have been identified (brevipila, gotlandica, stricta, suecica and tenuis) based on differences in habitat, phenology and morphology. LÄS MER

  5. 5. Morphometric differentiation in Papaver radicatum (Papaveraceae) : Geographic pattern and significance for refugial survival theory

    Författare :Eva Selin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Capsule morphology; Geographic pattern; Leaf morphology; Morphometric variation; Papaver radicatum; Refugial survival; Seed shape; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The morphometric pattern of variation among and within Scandinavian populations of the alpine species Papaver radicatum was studied. Results from analyses (including multivariate techniques) of capsule and leaf traits of wild-collected and cultivated plants as well as wild-collected seeds show correlated patterns of variation in capsule traits and partly corresponding patterns of variation between capsule and seed traits.
