1. Teaching for the learning of additive part-whole relations : The power of variation and connections
Abstract : In this thesis, results from four empirical studies and a re-analysis are synthesized with what can constitute a structural approach to teaching and learning additive part-whole relations among learners aged four to eight years. In line with a structural approach to additive relations, the relations of parts and whole are in focus from the outset and are seen as the basis for addition and subtraction (Davydov 1982; Neuman, 1987).

2. People in Between : Ethncity and Material Identity, a New Approach to Deconstructed Concepts
Abstract : In questions concerning ethnicity and cultural identity in prehistory, there is a great divide between the conclusions maintained on a theoretical level of discussion and the interpretations given to material remains, when these theories are practiced on the archaeological material. Inherited scientific and political structures, usage and ideas contribute to our understanding of ethnicity and the everyday use of the concept, and influence archaeological interpretations.

3. Variation Simulation Customized for Composites by Including FEM Simulations of Orthotropic Lamina
Abstract : The use of composite materials is increasing in many fields of production. Composite manufacturing, as well as other fields of production, suffers from uncertainties resulting in products that deviate from the specification. Geometry assurance is a common procedure used to keep the variations in product assemblies under control. READ MORE
