Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.
Äldre iraniers upplevelser på ett iranskt äldreboende : När frustation blir en del av livet
SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.
Epiphytic lichens associated with different traffic intensities along the highway E4
Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.
The Impact of Special Dividend and Redemption Announcements on the Swedish Stock Market
The aim with this study is to investigate the market reactions to announcements of special dividends and redemptions in Sweden and thus if these announcements can signal information. This study is an event study, where the event is the day of the announcement of a suggestion regarding issuance of special dividends or redemptions. The abnormal returns were estimated for two samples with the market adjusted returns model, one including special dividend announcing firms and the other redemption announcing firms. The signalling hypothesis and the hypothesis of a tax induced clientele effect are the most important hypotheses for this study. The efficient market hypothesis is another theoretical base that may explain the market reactions to the studied announcements, especially the pre-announcement activities that may occur.
Skogsmarksgödsling : en ekonomisk analys av olika gödslingsstrategier för ett skogsinnehav i norra Sverige
The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization.
The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.

Since it is a case study the findings can not be considered as general, but they can hopefully contribute the pedagogical discussion and future research.The findings show that there exists a difference between the expectations on policy level on the one hand and on the team level on the other hand.
Samspel mellan IT-avdelningen och affärsverksamheten : En studie av attityder
IT has become more evident in most organisations and has grown to be a part of the infrastructure rather than a tool for competitiveness. Therefore focus should now lie on how IT is adjusted to the business rather than on the usage of IT. To make the best use of IT in the business the CIO needs to start think more business-oriented instead of as before, technology-oriented. To develop the IT-department in that direction the IT-staff need to start cooperate with the business and gain knowledge about stakeholders, markets and the way of working for other staff members in the business.With this as a basis, the purpose of this thesis is to investigate attitudes regarding cooperation between the IT-department and the business and if there is any difference if the CIO has business related background or not.To fulfil the purpose a quantitative investigation with the help of surveys was conducted. The sample consisted of 18 companies with 100-200 employees in the area of Jönköping.
Geokemin inom osorterade cirklar : Analys av tungmetallers distribution inom jordprofiler tagna från Abiskoområdet, nordvästra Sverige
The Arctic region appears as a pristine remote environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).

Talsyntesen ? Dyslektikerns glasögonoch ett stöd för många läs- och skrivsvaga
According to the National Agency for Education 06-06-2010 are approximately 115 000 students graduating from Secondary School in the year of 2010.Out of these students, we know that thousands of them are hampered by reading and writing disabilities in various degrees. Have these students been given the best support needed when it comes to writing and reading?Compensation may be perceived as a goal for the pupil to catch up with the rest of the educational group or as a vehicle to go round the difficulties. In Sweden, diagnosed dyslexics are not allowed to use speech synthesis, a compensatory technical aid, during the 9th degree national tests.This study?s purpose is to discover if the usage of speech synthesis during the national test of Swedish and reading comprehension might work as a motivation booster for the students and consequently increase their test scores.This is a quantitative study including study including 15 pupils with diagnosed reading and writing disabilities.
