1. Incentives and Forest Reform: Evidence from China
Sammanfattning : Chapter I: Forest Devolution Reform in China: A Trigger for Investment or Deforestation? I investigate whether and how the devolution of forestland to households in China triggered investment in forestland, and its effect on forest resource conditions. The investment analysis is based on a panel dataset of a two-round survey of 3,000 households in eight provinces before and after the implementation of the forest devolution reform, while the analysis of resource conditions is based on satellite imagery on forest cover and vegetation during 2001-2012.

2. Long-range decision models in mining
Sammanfattning : Decision models for optimizing decisions in mining. Two principal models are presented:1) For optimizing the rate of production in a mine2) For optimizing the cut-off grade. The models are based on dynamic programming and simulate the economic consequences of alternative decisions. Computer programs containing the models are presented. LÄS MER
3. Oral health-related quality of life and young adults
Sammanfattning : The aims were to describe and analyse measures for oral health-related quality of life (OHRQOL) from a Public Health perspective and to determine young adults' views on dental care. The methods used included one literature review (Paper I) and one empirical study with qualitative design (Paper II). LÄS MER
4. Estimation of state and identification of complex modulus based on measurements om a bar traversed by waves
Sammanfattning : Estimation of state and identification of complex modulus based on measurements on non-uniform rods and beams have been studied theoretically and experimentally. Two principal cases were studied. In the first case, the material properties are fully known and the state at a section is to be estimated. LÄS MER
5. Aspects on the lacrimal drainage function
Sammanfattning : The aim of this project was to increase the knowledge on the function of the lacrimal passages. For this purpose, a quantitative test for the lacrimal drainage function is established: the drop test. Two principal parameters are introduced: the lacrimal drainage capacity and the blink output.
