1. 6. Misplaced Concreteness and Concrete Places : Critical Analyses of Divergent Discourses on Sustainability

   Författare :Carina Borgström Hansson; Humanekologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; Economics; Mainstream and counterpoint; Discourse; Place; Adaptive management; Genuine savings; Ecological footprint; Ecological economics; Bioregionalism; Sustainability; Environmental economics; Human ecology; Misplaced concreteness; economic theory; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

   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.

4. 8. On the value of land

   Författare :Stefan Hellstrand; Jinyue Yan; Pontus Cerin; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The issue of sustainable development is once again moving the production factor land into the focus of economic theory and practise. There are three production factors, capital, labour and land. Land is a synonym to ecosystems. During the major part of the 20th century land in economic theory has been handled as a peripheral issue. LÄS MER

5. 9. Aspects of Energy Resource Management

   Författare :Tomas Kåberger; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bio-energy; value; interdisciplinary; life-cycle analysis; tax-shift; resource; energy; electricity;

   Sammanfattning : Energy resource management requires input from many disciplines. The three first papers in this thesis deals with the use of physical terms in the interdisciplinary process where inputs from different disciplines are handled together. LÄS MER

7. 10. Spatial Spread of Organisms : Modeling ecological and epidemiological processes

   Författare :Tom Lindström; Uno Wennergren; Colleen Webb; Linköpings universitet; []
   Nyckelord :Spatial kernel; Spatially explicit modeling; Disease transmission; Animal movements; NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : This thesis focuses on the spread of organisms in both ecological and epidemiological contexts. In most of the studies presented, displacement is modeled with a spatial kernel function, which is characterized by scale and shape. These are measured by the net squared displacement (or kernel variance) and kurtosis, respectively. LÄS MER
