This thesis consists of an introduction and four self-contained chapters that address issues of how organizations and institutions should be designed in order to provide adequate incentives and enable coordination. The first essay uses a multi-task principal-agent model to examine two reasons why coordination problems are common when public sector organizations share responsibilities: the incenti
Despite efforts to stimulate the dissemination of green purchasing practices, their uptake in business and industry has so far proven limited. Reasons for the limited progress remain largely unclear. One factor explored in this thesis, is the role of information in the operationalization and dissemination of green purchasing in organizations and supply chains. The importance of knowledge and infor
Obesity is globally prevalent and highly heritable, but its underlying genetic factors remain largely elusive. To identify genetic loci for obesity susceptibility, we examined associations between body mass index and similar to 2.8 million SNPs in up to 123,865 individuals with targeted follow up of 42 SNPs in up to 125,931 additional individuals. We confirmed 14 known obesity susceptibility loci
Background: Although uncomplicated cystitis is often self-limiting, most such patients will be prescribed antibiotic treatment. We are investigating whether treatment of cystitis with an NSAID is as effective as an antibiotic in achieving symptomatic resolution. Methods/Design: This is a randomized, controlled, double blind trial following the principles of Good Clinical Practice. Women between th
Objective: to describe the experiences of immigrant parents of an ultrasound examination in the second trimester of pregnancy, highlighting information, communication, thoughts, feelings and well-being. Methods: An exploratory, qualitative study using in-depth interviews with parents separately. Content analysis was used. A total of nine Farsi-speaking couples, in all 18 persons, who now live in S
The purpose of the thesis is to study whether any special professional norms exist with regard to principals’ leadership of the democratic mission which is presented to the schools. The aim is to identify norms in order to be able to later analyse and understand them. Norms exist in groups of various types, and by using the term “norm” I am addressing the actions of principals, rather than their i
Sulfate adsorption is an important process when modeling the dynamics of recovery from acidification. In the dynamic soil chemistry model SAFE sulfate adsorption is modeled by a pH and sulfate concentration dependent isotherm. This isotherm has been parameterized by fitting it to data from batch experiments on soil samples using multiple linear regression. The soil samples were from the B-horizon
A modelling and simulation study regarding the heat transfer in hot pressing as well as in impulse drying of paper has been performed. The study is focused on modelling the heat transfer from a hot surface to a moist paper sheet and the heat transfer inside the paper sheet. The model is based on solving the equation for unsteady heat transfer by conduction. The model was compared with experimental
