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

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

    Abstract : 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. READ MORE

  4. 2. Immigrant entrepreneurs in a changing institutional context : a mixed embeddedness approach

    Author : Aliaksei Kazlou; Martin Klinthäll; Susanne Urban; Karl Wennberg; Monder Ram; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Immigrant entrepreneurs; Mixed embeddedness; Entrepreneurial process; Institutional change; Invandrarföretagare; Mixed embeddedness; Entreprenörsprocess; Institutionell förändring;

    Abstract : Immigrant entrepreneurs are known to be heterogeneous in terms of available resources and entrepreneurial outcomes. However, this heterogeneity, as well as immigrant entrepreneurs’ embeddedness in social networks and the institutional context of high-income welfare states such as Sweden, remains understudied.

    Abstract : Water is essential for human well-being and healthy ecosystems, but population growth and changes in climate and land-use are putting increased stress on water resources in many regions. To ensure water security, knowledge about the spatiotemporal distribution of these resources is of great importance. READ MORE

  6. 4. From Conceptual Links to Causal Relations — Physical-Virtual Artefacts in Mixed-Reality Space

    Author : Thomas Pederson; Lars-Erik Janlert; William Buxton; Umeå universitet; []

    Abstract : This thesis presents a set of concepts and a general design approach for designing Mixed Reality environments based on the idea that the physical (real) world and the virtual (digital) world are equally important and share many properties. Focus is on the design of a technology infrastructure intended to relieve people from some of the extra efforts currently needed when performing activities that make heavy use of both worlds.
