This thesis examines the emissions costs of Swedish aviation and their degree of internalisation under current economic instruments. The results show that the degree of internalisation spans from practically zero for a long-haul flight to 6 per cent for a typical domestic flight, where the climate cost, including high-altitude impact, makes up the main part of the cost. To inform evaluation of the consequences of this underinternalisation, or attempts to correct for it using price instruments, the price and income elasticities of international leisure air travel from Sweden are estimated using household expenditure data and two different price measures. The resulting elasticities are very high ? 2.03 or 2.04 for the income elasticity and -2.53 or -1.88 for the price elasticity ? and should be interpreted cautiously due to data limitations, especially for the price elasticities.

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.

There is two dairy farms in Sweden with ability to be opened on both long sides, one outside Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results or not enough literature about natural ventilation and especially on this kind of air inlet, makes my tests very interesting not only on Alnarp, but among other companies. I would like to find out if there is any air movements direct on the cows, how high/low temperature, air humidity, light intensity and noise standard inside the barn. Does Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could this system become the new dairy barn instead of the conventional barns in Sweden? I am going to focus on the animals environment, after all they are the one who is going to spend the most of the time in the barn. I used five electrical loggers distributed inside the barn to measure the temperature and one of the loggers measured the air humidity, every 15th minute. One logger were placed on the outside which measured both temperature and air humidity.

This thesis treats the development of the European Union asylum- and migration politics and the EU member states transfer of authority to the European Union. The main purpose has been to look closer with the use of the application of theory of neofunctionalism and liberal intergovernmentalism on the European Union case. The focus will be to answer the following questions: How has the political development within EU asylum and migration policy developed through the period of The Single European Act to the ratification of the Stockholm program? And how can the chosen theory explain European countries transfer of national decision regarding asylum policy in favor of a supranational European asylum policy? Based on the available material of European Union programs and harmonization measures for this area I have attempted to understand to what extent the European Union?s development in the area of the asylum and migration politics can be explained through the theories of neofunctionalism and liberal intergovernmentalism. The result of my analysis is confirmation of the European Union development of the area of the asylum and migration policy and also a series of explanations according to the theories regarding the member states transfer of authority to the EU.

This thesis examines the effects of proximity operators and query expansion with synonyms on retrieval performance. The queries were expanded with synonyms and structured with proximity operators where the permitted distance between terms varied from 1 to 3. The expansion terms were selected from the online lexical reference system WordNet. Initial query terms were selected from 28 topics that contained compound words and were chosen on the basis of their expandibility. The English morphological analyser ENGTWOL was used for normalization of query terms.

Assessing the outcome of corporate responsibility is often argued to be complicated due to long-term effects and qualitative aspects. Epstein (2008, p.261) establishes that: ?Though many think that sustainability is too difficult to measure, companies have found that unless the impacts are measured, they are commonly ignored in the resource allocation process?. Corporate responsibility is often referred to as a business case, i.e., that social and environmental concern add value to the business (Heikkurinen, 2010; Porter & van der Linde, 1995). Hence, for corporate responsibility to be a business case a strategy, corporate structure and systems, programmes and actions linked to performance measures need to be in place to assess the outcome; environmental, social as well as financial.

In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Most scientists believe that in the good times the peasant had the opportunity to follow fashion. Virestad parish does not follow fashion. My purpose is to try to understand something of the mechanism that made Virestad do so: that I will do by analyzing the results in relation to the concept of status. My main source is estate inventories. Here I examine the status markers and differences in what they invested in clothes and jewelry in relation to the estate's proceeds.The lower the balance, the more percentage they need to put on clothes.

The purpose of this study was to describe and analyses educators? experiences of reflective conversations in their teams and part of teams in relation to their work with pupils in need of special support. Ten educators representing ten different teams have been interviewed since all had experiences of working in teams and working with pupils in need of special support. Focus has been on the educators? experiences of the organisation, the effects of the reflections and the need to develop the reflective conversations in their teams and part of teams.

ABSTRACTBackground and aims: Nutrition is a part of the medical treatment, and also a part of the nursingcare. In spite of this, malnutrition is a common problem in the health care sector. Studies show thatnurses have too little knowledge about nutrition and malnutrition and that nutrition has low priorityin the daily work. The aim with this study was to find out the nurses self-reported knowledge aboutand their attitudes towards malnutrition, nutrition screening, prevention and treatment of patientswith malnutrition.Methods: A questionnaire was handed out to 65 nurses in two different care units and 36questionnaires were answered.Results: The respondents from the two care units self-reported their knowledge about nutrition andmalnutrition low. Most of the respondents stated to have a big need of education about nutritionscreening and more than half of the respondents stated that they have a need of education forprevention and treatment of malnutrition.

Bakgrund och problem: Med den ökande efterfrågan på vård men med begränsade möjligheter att utöka sjukvårdens resurser finns ett stort behov av förbättringskunskap inom vården. Det är allt vanligare att sjukvården hämtar inspiration till förbättringsarbete från industrin i syfte att öka effektiviteten och hålla en hög kvalitet.Syfte: Studiens syfte är att beskriva och analysera hur intensivvårdsavdelningen (IVA) på Danderyds sjukhus arbetar med löpande förbättringsarbete samt att baserat på analysen ge rekommendationer om hur detta arbete kan utvecklas. Ett bisyfte är att inom ramen för IVA:s förbättringsarbete undersöka det stöd från kvalitet- och verksamhetsutvecklingsfunktionen på Danderyds sjukhus som IVA kan nyttja och att ge förslag på hur detta stöd kan utvecklas.Metod: Denna kvalitativa fallstudie genomfördes på intensivvårdsavdelningen (IVA) vid Danderyds sjukhus. Datainsamlingsmetoderna som användes är semi-strukturerade intervjuer, dokumentstudier och observation. Analysen skedde genom mönsterjämförelse.Resultat: Det främsta förbättringsarbetet som genomfördes på IVA var genom förbättringsteam med ansvar över att utveckla vissa områden inom vården.

Since the role of the libraries as merely a place for loans has decreased, the importance of giving the visitors a total experience has increased.The aim of my thesis was to investigate whether a change in the sound environment at the library of Jokkmokk could generate more satisfied visitors, whether they are borrowers or use the library for other purposes. The change in the sound environment was to be effected by means of a background sound experiment in the magazine room at the library. Action research was used as a research strategy and observations and interviews as method to collect data.The experiment was conducted with two selected sounds of nature: birdsong and a rippling brook. The observations and interviews were executeted in three stages: 1. Without any background sound.
