1. 1. Families of cycles and the Chow scheme

   Författare :David Rydh; Dan Laksov; Martin Olsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Families of cycles; Chow scheme; Hilbert scheme; zero-cycles; divided powers; symmetric tensors; symmetric product; Weil restriction; norm functor; Algebra and geometry; Algebra och geometri;

   Sammanfattning : The objects studied in this thesis are families of cycles on schemes. A space — the Chow variety — parameterizing effective equidimensional cycles was constructed by Chow and van der Waerden in the first half of the twentieth century. Even though cycles are simple objects, the Chow variety is a rather intractable object. LÄS MER

   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backcasting; decision processes; ecodesign; integrated; product development; sustainability principles; sustainable product development; strategic sustainable development;

   Sammanfattning : Product development is a particularly critical intervention point for the transformation of society towards sustainability. Current socio-ecological impacts over product life-cycles are evidence that current practices are insufficient. LÄS MER

5. 4. The Collaborative Challenge of Product Development : Exploring Sustainable Work Systems Through Critical Incidents in R&D Alliances

   Författare :Lars Uppvall; Matti Kaulio; Pär Åhlström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R D Alliances; product development; sustainable work systems; critical incident technique; operational work; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : The aim of this thesis is to empirically study challenges and opportunities in the operational work in contract-based R&D alliances in order to increase the understanding of this type of work system and explore how these work systems could be sustainable. Based on the concept of sustainable work systems, this thesis addresses issues of how work in R&D alliance should support both the competitiveness of the firm as well as regeneration of human resources.

7. 5. Empirical essays on unemployment and business cycles

   Författare :Erik Hegelund; Rodney Edvinsson; Fredrik N G Andersson; Josef Taalbi; Jan Ottosson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; business cycles; Okun’s law; unemployment; capital formation; temporal disaggregation; band spectrum regression; wavelet analysis; ekonomisk historia; Economic History;

   Sammanfattning : This dissertation examines business cycles in Sweden, and the patterns in and driving forces of short- and long-term movements in unemployment in a selection of high-income countries throughout the 20th century. While this has been studied numerous times before, this dissertation starts from the point of view that there is no consensus in social science on how to understand these phenomena. LÄS MER
