  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.

  3. 2. Mellan orten och kalifatet : En studie om utresandefenomenet

    Författare :Sara Johansson; Björn Johansson; Göran Larsson; Marcus Herz; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Islamic State; Radicalization; Foreign fighters; Especially vulnerable areas; Territorial stigmatization; Social representations; Moral disengagement; Social Work;

    Sammanfattning : Starting 2011, many travelled from other countries to support different parties of the Syrian revolution. Many came from Sweden, and many joined the Islamic State. Swedish “Syria travellers” often came from areas labelled as [especially] vulnerable. LÄS MER

  4. 3. Algorithmically Guided Information Visualization : Explorative Approaches for High Dimensional, Mixed and Categorical Data

    Författare :Sara Johansson Fernstad; Mikael Jern; Jimmy Johansson; Jane Shaw; Matthew O. Ward; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information visualization; data mining; high dimensional data; categorical data; mixed data;

    Sammanfattning : Facilitated by the technological advances of the last decades, increasing amounts of complex data are being collected within fields such as biology, chemistry and social sciences. The major challenge today is not to gather data, but to extract useful information and gain insights from it. LÄS MER

  5. 4. Geometrical controls on spectral induced polarization in time and frequency domain

    Författare :Sara Johansson; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral induced polarization; Microstructure; Electrical properties; Tomography; Multiscale;

    Sammanfattning : What can we learn by transmitting electrical currents through electrodes in the ground? Geophysical methods can help us to locate the bedrock, valuable mineral ores, remains of ancient buildings and many other secrets hiding below the surface. However, it is not only the universal interest for the unknown that drives the geophysical research forward. LÄS MER

  7. 5. From microstructure to subsurface characterization. Spectral information from field scale time domain induced polarization

    Författare :Sara Johansson; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geofysik; Inducerad Polarisation;

    Sammanfattning : A large variety of subsurface infrastructure projects of different types can gain valuable information from tomographic measurements of subsurface physical properties. With resistivity and time domain spectral induced polarization (IP), the distributions of the conductive and capacitive properties of the subsurface are obtained. LÄS MER
