   Sammanfattning : The aim of this thesis is to study trust in military leaders. Empirical data was gathered through interviews and questionnaires with military personnel mostly from Sweden, but also from four other European countries. LÄS MER

3. 12. Brain networks in time : deriving and quantifying dynamic functional connectivity

   Författare :William Hedley Thompson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Studying the brain’s structure and function as a network has provided insight about the brain’s activity in health and disease. Networks in the brain are often averaged over trials, frequency and time and this is called functional connectivity. This thesis aims to extend the analyses beyond these assumptions and simplifications. LÄS MER

4. 13. Cross-functional brain imaging of attention, memory, and executive functions : Unity and diversity of neurocognitive component processes

   Författare :Petter Marklund; Lars Nyberg; Akira Miyake; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human memory; executive functions; prefrontal cortex; sustained and transient neural activity; declarative long-term memory; attention; working memory; functional neuroimaging; cognitive control.; Psychology; Psykologi;

   Sammanfattning : The central theme of the present thesis revolves around the exploration of similarities and differences in brain activity patterns invoked by the component processes underlying mnemonic, executive and attentional functions. The primary aim was to identify and functionally characterize commonly recruited brain regions in terms of shared component processes, which has been a largely neglected area of research in cognitive neuroscience.

5. 14. Flip Zooming. The development of an information visualization technique

   Författare :Staffan Björk; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information visualization; human-computer interaction; flip zooming; human-computer interaction;

   Sammanfattning : This thesis describes the development of a Focus+Context information visualization technique called Flip Zooming. Based on two initial examples of the technique, the work reported here expands the description and functionality of the technique by the development of a number of applications as well as by some theoretical contributions.

7. 15. Chemistry: content, context and choices : towards students' higher order problem solving in upper secondary school

   Författare :Karolina Broman; Eva Silfver; Dan Johnels; Judith Bennett; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; chemistry education; upper secondary students; meaningful learning; higher order thinking; problem solving; context-based learning; interest; educational choice; identity; kemididaktik; didactics of chemistry;

   Sammanfattning : Chemistry is often claimed to be difficult, irrelevant, and uninteresting to school students. Even students who enjoy doing science often have problems seeing themselves as being scientists. This thesis explores and challenges the negative perception of chemistry by investigating upper secondary students’ views on the subject. LÄS MER
