Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys
The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010.
More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.
En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet
The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which Measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred Measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to Measure relative recall have been performed but they all suffer from different defects.
Amning som preventiv åtgärd mot plötslig spädbarnsdöd : En litteraturstudie
ABSTRACTObjectiveThe aim of this study was to determine if and what kind of scientific evidence there is for the advice that breast-feeding can reduce the risk of sudden infant death syndrome (SIDS). The aim was to investigate research on the subject published in the last 15 years.MethodA systematic review without meta-analysis with relevant original articles published in the last 15 years.Main resultsAfter searching for articles 26 relevant articles were used for this study and two were excluded because of poor quality. Mixed results were shown on breast feeding and the risk of SIDS. Breast-feeding seems to have some protective effect but can?t be separated from known risk factors of SIDS.Plain language summaryBreast feeding can be regarded as a preventive Measure against SIDS.
Piotroski ur ett riskperspektiv : En empirisk studie av 3- samt 4-faktors CAPM
An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) Measure of financial performance, F_SCORE.
Övervikt och fetma hos barn och ungdomar : Orsaker, konsekvenser och åtgärder
The purpose of this essay was to get some knowledge about how the situation was for children with overweight and obesity. I wanted to examine what experience about causes, consequences and Measure the professionals, who meets children in different situations in their daily work had, and I wanted to find out which explanations current research had about the problem.The knowledge I have acquired during my work with this paper about the problem was that it was depending on many different factors on various stage in the child's life which influences and interacts with the child in its development. The risk that a child would develop overweight was amongst other things depending on the child's eating- and exercising habits.This habit was formatted for example by the circumstances in the family, availability of sweets/food and the choice of leisure time activities.The consequences for the overweight/obese children could be that the child did not manage to keep up with its friend's physical activities which led to a sense of rejection, risk of being bullied by friends, the risk of a damaged physical and psychic health. The problem was not easy to Measure and all of the studies demonstrated that parental involvement is necessary in an effective treatment of childhood obesity..
DEHP - från mjukgörare till hormonstörande
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate Measure for phosphorus.
Nationell Moralsyn? : Om betydelsen av nationell tillhörighet för ungdomars moral.
Denna undersökning syftar till att undersöka nationella skillnader i moralutveckling och innehåll i moraliskt resonemang. Studien omfattar 445 svenska och 148 amerikanska ungdomar i åldern 14-19 år. De svenska fpp är hämtade från högstadium och gymnasium i Stockholmsområdet, och de amerikanska från två katolska privatskolor i New York. Dessa tog del av ett moralfrågeformulär av Gibbs (Gibbs & Widaman, 1982; Socio-moral Reflection Measure; SRM) som är en reviderad version av Kohlbergs intervjumetod för bedömning av en individs moralutveckling och kvalitativa, moraliska synsätt i frågor rörande moral. Vid analysen förelåg inga nationella skillnader i moralutvecklingsnivå.
Vanebeteende - Det lojala beteendet?
The Swedish sports retail industry has experienced extensive growth during the last decade, and this has attracted new entrants to the market, both start-ups and international followers. This has inevitably put more pressure on incumbents, which are now confronted with major challenges as how to retain their customers and market shares. Customer loyalty has been proved to be an important factor for customer retention and proposed to constitute inertia of switching behavior. In light of this problematization, the purpose of this study is to describe the underlying factors of loyalty and whether purchase habits could further explain customer loyalty. The aim is also to understand the strategic implications of the factors involved.
Att mäta generell skam : En analys baserad på Raschmodellen
The purpose of this paper was to investigate whether Suzanne Retzinger?s linguistic cues for shame and verbal behaviors for hiding shame could be used to Measure shame in surveys based on Thomas Scheff?s theory of shame. I created a Measurement instrument consisting of 30 statements, which were all meant to Measure general shame.The instrument was administrated to 180 respondents studying at Karlstad University, of whom 4 respondents were removed from the data set due to lack of standardization. With the polytomous rasch model used for the analysis, data from 176 respondents were analyzed, of whom 124 respondents were female and 52 were male.The result showed that the Measurement instrument?s statements should not be used together because the analysis indicated multidimensionality.

Utvärdering av ett värmepumpsystems prestanda till en HWC-tvättmaskin : Med fokus på fläktvarvtal och köldmedieflöde
This report was performed in order to evaluate a new technological Measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.
Bäckmans stenhuggeri AB : Möjligheten att skapa ett nytt segment inom stenbranschen
The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for Measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to Measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.
Kombinationsbruk, talltimmer och vilt?
When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.
Kosovo - Självständighetens betydelse och möjligheter : En fallstudie i demokratiutveckling
The aim of this study is to examine the democratization process of Kosovo in the years after the countries independence was assured. Two central questions for the case study consist of whether a democratic improvement in the country has occurred and which factors, positive and negative, are present to further improve or impede the democratizationprocess. The study builds upon two central definitions, democratic states and democratization in order to gain theoretical background to be able to Measure these two quite abstract expressions. A socioeconomic model is used to Measure favorable or negative developments within Kosovos society and the findings of this model confirms the hypothesis of modernization theory, namely that increased socioeconomic development increases the chance of a positive democratizationprocess. There has been a positive democratic development aswell as socioecomic progress but since the nature of this study is merely descriptive and not explanatory, it doesnt make claims on the explanatory power of modernization theory.
