   Keywords : 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;

   Abstract : 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. READ MORE

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

   Author : Lars Uppvall; Matti Kaulio; Pär Åhlström; KTH; []
   Keywords : 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;

   Abstract : 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.
