2. 1. Strategic Interactions among Swedish Local Governments

   Author : Karin Edmark; Matz Dahlberg; Sören Blomquist; Jan Brueckner; Uppsala universitet; []
   Keywords : Economics; Strategic Interactions; Spatial Interactions; Tax Competition; Welfare Competition; Fiscal Federalism; Nationalekonomi;

   Abstract : Essay 1 (with Matz Dahlberg) investigates if local governments react on the welfare benefit levels in neighbouring jurisdictions when setting their own benefit levels. The IV estimates indicate that there exists a "race-to-the-bottom" and that the effect is economically as well as statistically significant. READ MORE

4. 2. Non-local behaviour from local interactions

   Author : Thomas Kvorning; Thors Hans Hansson; Ady Stern; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Abstract : With the discovery of the quantum Hall effect more than thirty years ago, a whole new field emerged—that of topological quantum matter. This field is now a very mature one, and many different aspects are covered in the literature. READ MORE

5. 3. Species interactions and community structure

   Author : Peter Frodin; Technology and Social Change (WTS) Centre for Work; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; spatial structure; local stability; enrichment; species interactions; Community structure; population dynamics;

   Abstract : In this theses I have focused on how the mechanisms of species interactions affect community structure. It is well known that certain species may have a particularly strong influence on the structure of a community. What is not fully understood is how to characterize these species that have such a strong impact on community structure. READ MORE

6. 4. Cascading extinctions in food webs : local and regional processes

   Author : Anna Eklöf; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cascading extinctions; complexity; connectance; dispersal; food web; local dynamics; regional dynamics; resistance; spatial structure; species loss;

   Abstract : Ecological communities all over the world are loosing biodiversity due to different kinds of human activities and there is an urgent need of understanding how those losses affect the function of the ecosystems on which we all depend. The community's response to species losses is likely to depend on both the structure of the local community as well as its interactions with surrounding communities. READ MORE

7. 5. Modulating magnetic interactions : in metamaterials and amorphous alloys

   Author : Nanny Strandqvist; Björgvin Hjörvarsson; Alexei Vorobiev; Sean Langridge; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; interlayer exchange coupling; superlattice; mesospins; magnetic nanostructures; emergence; amorphous alloys; CoAlZr; FeZr; Fysik; Physics;

   Abstract : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. READ MORE
