1. 11. Inequality, Health, and Smoking

   Författare :Gustav Kjellsson; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Health Inequality; Inequality measurement; Smoking; Survey Methods; Health survey; Hospitalization; Recall error; Recall periods; Concentration index; bounded variables;

   Sammanfattning : This thesis consists of five self-contained, yet related, research papers, which all contribute to the economic literature on socioeconomic differences in health and health related behavior. The first two papers provide a compass in the discussion of how to measure health inequality and, more specifically, how to adjust measures and concepts when moving from an unbounded income variable to a bounded (or binary) health variable.

3. 12. On specification and inference in the econometrics of public procurement

   Författare :David Sundström; Kurt Brännäs; Sofia Lundberg; Michael Visser; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; auctions; dependent variable transformation model; green public procurement; indirect inference; instrumental variable; latent variable; log-generalized gamma distribution; maximum likelihood; measurement error; non-linear least squares; objective effectiveness; orthogonal polynomial regression; prediction; simulation estimation; structural estimation; nationalekonomi; Economics; Econometrics; ekonometri;

   Sammanfattning : 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. LÄS MER

5. 14. Prediction of Medical Device Usability Problems and Use Errors - An Improved Analytical Methodical Approach

   Författare :Lars-Ola Bligård; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Methodological Research; Usability; Human Error; Medical Equipment;

   Sammanfattning : The aim of medical care is to make people healthier, and this is pursued with great success today. Unfortunately, medical care also entails injuries to certain patients. Some of these injuries are caused by use errors. Research has shown that lack of usability of medical equipment is a strongly contributing cause of use errors. LÄS MER

7. 15. Geophysical 3D models of Paleoproterozoic Iron Oxide Apatite mineralization’s and Related Mineral Systems in Norrbotten, Sweden

   Författare :Oskar Rydman; Maxim Smirnov; Thorkild Maack Rasmussen; Tobias Bauer; Niklas Juhojuntti; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Magnetotellurics; 3D Inversion modelling; Classification; Potential fields; Mineral system; Petrophysics; mineral exploration; common earth modeling; iron oxide-apatite; Northern Norrbotten ore province; Tillämpad geofysik; Applied Geophysics;

   Sammanfattning : The Northern Norrbotten ore district hosts a multitude of Sweden’s mineral deposits including world class deposits such as the Malmberget and Kirunavaara Iron oxide apatite deposits, the Aitik Iron oxide copper gold deposit, and a multitude of smaller deposits. Northern Norrbotten has been shaped by tectonothermal events related to the evolution of the Fennoscandian Shield and is a geologically complex environment. LÄS MER
