1. Coordinated control of Multi-Stage Inventory System
Sammanfattning : This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. LÄS MER
2. Speciation and Metabolic rate : Insights from an avian hybrid zone
Sammanfattning : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. LÄS MER
3. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses
Sammanfattning : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. LÄS MER
4. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight
Sammanfattning : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. LÄS MER
5. Misplaced Concreteness and Concrete Places : Critical Analyses of Divergent Discourses on Sustainability
Sammanfattning : This dissertation critically examines the tension between mainstream and counterpoint perspectives on sustainability on the basis of analyses of four approaches to this issue: environmental economics, ecological economics, adaptive management, and bioregionalism, which are presented as successive attempts to challenge mainstream, modernist perspectives on socio-ecological relationships. The different worldviews and identity constructions associated with the two extremes in this spectrum of approaches are examined on the basis of interviews with environmental economists and bioregionalists in California.
