1. On Young tableau involutions and patterns in permutations
Abstract : This thesis is dealing with the combinatorics of permutations in three different aspects. In the first two papers, two flavours of pattern avoiding permutations are examined and in the third paper Young tableaux, which are tightly related to permutations via representation theory, are studied.

2. The Diamond Lemma for Power Series Algebras
Abstract : The main result in this thesis is the generalisation of Bergman's diamond lemma for ring theory to power series rings. This generalisation makes it possible to treat problems in which there arise infinite descending chains. READ MORE

3. On specification and inference in the econometrics of public procurement
Abstract : In Paper [I] we use data on Swedish public procurement auctions for internal regularcleaning service contracts to provide novel empirical evidence regarding green publicprocurement (GPP) and its effect on the potential suppliers’ decision to submit a bid andtheir probability of being qualified for supplier selection. We find only a weak effect onsupplier behavior which suggests that GPP does not live up to its political expectations. READ MORE

4. Technology use in everyday activities among older adults with mild cognitive impairment : a study of changes over time and views on technology as support
Abstract : The overall aim of this thesis was to provide new knowledge of everyday technology (ET) use and functioning over time, as perceived by persons with cognitive decline due to mild cognitive impairment (MCI). A secondary aim was to increase knowledge about their views on technology as part of and as potential support in everyday life. READ MORE

5. Transition Metal Nitrides : Alloy Design and Surface Transport Properties using Ab-initio and Classical Computational Methods
Abstract : Enhanced toughness in brittle ceramic materials, such as transition metal nitrides (TMN), is achieved by optimizing the occupancy of shear-sensitive metallic electronic-states. This is the major result of my theoretical research, aimed to solve an inherent long-standing problem for hard ceramic protective coatings: brittleness. READ MORE
