1. 1. In search of known unknowns : an empirical investigation of the peripety of a knowledge management system

   Författare :Leon Michael Caesarius; Jan Lindvall; Lars Engwall; Jannis Kallinikos; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; knowledge management systems; knowledge management endeavours; knowledge management; knowledge; knowledge creation; information technology; automating; informating; Business studies; Företagsekonomi;

   Sammanfattning : In their quest to secure their level of competitiveness, organizations have turned their attention to a specific type of information technology (IT) solution referred to as knowledge management systems (KMS). Research recurrently views and defines such system as IT-tools that mainly enable the collection, storing and diffusion of knowledge within the boundaries of the organization. LÄS MER

   Sammanfattning : Diffusion MRI (dMRI) sensitizes the MR signal to the diffusion of water molecules at the microscopic level and thereby non-invasively probes tissue microstructure. This is relevant when determining biological properties of tissues, for example, cancer type and its malignancy. LÄS MER

4. 3. Diffusion of systemic innovations in the construction sector

   Författare :John Lindgren; Stephen Emmitt; Kristian Widén; Fawzi Halila; Jack Goulding; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Sector; Innovation Diffusion; Systemic Innovation; Knowledge Integration; Knowledge Development;

   Sammanfattning : The amount of research dealing with innovation has increased dramatically, construction management research included. This thesis focuses on innovations with inter-organizational effects, systemic innovations, which may radically change and improve the construction process. LÄS MER

5. 4. Perspectives on Knowledge and Growth

   Författare :Ola Olsson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Growth theory; knowledge; human capital; technology; university policy; biogeography; epistemology; long-run development;

   Sammanfattning : This thesis deals with various aspects of the relationship between knowledge and economic growth. It contains a general introduction and five separate essays. Essay I is a literature overview on the appearance of knowledge in modern growth theory. LÄS MER

7. 5. Investigation of Water Mobility using Diffusion-Sensitive MRI: The Role of q-Space Imaging, High b-Values and Diffusion Time

   Författare :Jimmy Lätt; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; kurtosis; high b-value; diffusion; diffusion time; NMR; q-space;

   Sammanfattning : Nuclear magnetic resonance (NMR) diffusometry provides important information about molecular motion on a microscopic scale. The advantage of NMR diffusometry is its ability to characterise microstructures non-invasively. This has made the method important not only in chemistry, biochemistry and materials science, but also in medicine. LÄS MER
