This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Sedan tidigt 90-tal har det pågått en diskussion om den evidensbaserade praktikens vara eller inte vara inom socialtjänsten. Evidensbaserad praktik är en metod där den bästa tillgängliga evidensen, den egna erfarenheten samt klientens preferenser utgör grunden för professionella beslut. För att möjliggöra en sådan praktik måste bedömningar och dokumentation inom socialtjänsten utföras mer standardiserat. Förespråkarna, däribland Socialstyrelsen, menar att arbetets och insatsers effekt måste kunna mätas för att förbättras. Importen av evidensbaserad praktik i socialtjänst är dock förknippat med en rad svårigheter och vissa menar att det är ett hot mot de professioner som finns inom det sociala arbetet.

The purpose of this study was to explore young people's participation and experience of participation in child protection investigations. The study was conducted using qualitative methodology and is based on interviews with four adolescents aged 13-19 years old who have experience of child protection investigations. Our chosen method has made it possible for us get a deeper understanding of young people's own experiences of participation. In order to analyze the material we have used Shiers (2001) model of children's participation, symbolic interactionism, and some concepts relating to shame and pride.The results show that all adolescents have had the opportunity to be heard during the investigations, but it is different to what degree they feel that someone has listened to them.Two of the young people have been involved in their investigation, been listened to and have had impact on the decisions taken. The results indicate that it does not seem to be the external factors, such as how many meetings they have had, or what quality it was on the information, that matters if the social worker did not manage to convey to the young people that what they told was of any importance.

The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.

In 2006 there was a change in LMA (1994:37) that clarified the division of responsibility be-tween the Migration Board and the municipalities, concerning unaccompanied children. The social services should now be utmost responsible for the housing and care of these children, to assure that they gain the same standards and rights as all other children. The aim of this essay has been to examine how the division of responsibility has influenced the work of the social services and how they interpret their responsibility for the unaccompanied children. How do the social services investigate and make decisions concerning these children? Do these chil-dren have the same rights as other children? To answer these questions a legal study was made, followed by qualitative research interviews with four social services that receive unac-companied children.

Bakgrund: Länge har paybackmetoden, nettonuvärdesmetoden och andra diskonteringsmetoder haft en ledande ställning när företag gör sina investeringsbedömningar. Metoderna har fått kritik för att inte ta hänsyn till beslutsfattarnas flexibilitet och på så sätt underskatta värdet av en investering.Syfte: Syftet med uppsatsen är att utreda i vilken utsträckning svenska företag använder sig av reala optioner och förklara varför metoden inte används i större utsträckning. Vidare syftar uppsatsen till att förklara varför användningen skiljer sig mellan USA och Sverige. Ytterligare ett syfte är att undersöka vilka kapitalbudgeteringsmetoder som används i Sverige idag .Metod: I uppsatsen har främst en kvantitativ metod använts i form av en enkätundersökning. Metoden kompletterades senare med den kvalitativa metoden, då i form av en intervju med en användare av reala optioner.Slutsatser: Payback- och DCF-metoden dominerar fortfarande bland de svenska företagen.

The aim of this thesis is to investigate which the main determinants of capital structure in Swedish listed firms are and to identify which incentives lies behind managers choice of capital structure determinants. Further, the study investigates whether the Post Keynesian theory and theories which incorporate behavioral aspects can be used to explain the capital structure decisions or if the traditional Neoclassical theory give an better explanation. We have used a qualitative method to analyze the determinants of capital structure and the managers incentives behind capital structure decision. We conducted a survey which was sent to 83 Chief Financial Managers and financial executives in Swedish firms listed on Mid Cap or Large Cap.

I want to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this project will give us more work during the winter. I also want to take as much material as possible for heating from our farm in order to increase the value of the products from the farm. The project is in a village near us, where we should support a school, a churh, a home for the aged, a kindergarten and a parish hall with heat. In my work I have compared two different alternatives with each other. The first alternative is to put a central heater in one of the buildings, the home for the aged, in which we will burn oat.

The society strives for sustainable development, in the construction industry it is expressed through sustainable building. Energy and LCC analyzes increases the ability to make conscious decisions in the process. A problem in the construction industry is that energy and LCC analysis is not used to the desired extent, as they are perceived as complicated and time consuming. The report aims to achieve a more sustainable building through increased use of energy and LCC analyzes.The goal is to show how BIM can be used to improve the efficiency of the energy and LCC analyzes.The study was conducted with a literature review and a case study to answer which information that is required in a BIM model to perform energy and LCC analyzes. The study also shows which software can be used in BIM based energy and LCC analyzes and how the analyzes can be carried out efficiently.The result shows that effective analyzes may be performed if the BIM-model contains the relevant information for making analyzes.

The purpose of this study was to examine customer attitudes towards flagship stores and how they perceive them. To ascertain this, and obtain answers to the research questions covering the study's main issues, we decided to turn to the customers who recently visited a flagship store.Our background theory is based upon literature from previous research done on the subject in the form of scientific articles and books. We present the theoretical concept that explains how flagship stores are used as a marketing tool and what impact they have on the new market. These will be helpful in answering our questions when we evaluate our results.!A theoretical framework, consisting of three value dimensions, was used as a support throughout the implementation of the study. These three values; hedonic, practical and social, should give us a better idea of what customers experience and what they value when they visit the flagship stores.!The method used in our investigation is of quantitative form, so that it can be feasible on a large crowd to thus contribute to a quantitative result.

The means to political participation at the local level in Sweden are changing and this change is analyzed through a case study. The first aim is to explore the forms of public political participation in Swedish municipal Älvkarleby, namely public question time in local government, citizen motions and open meetings. A part of this is also to analyze he every day contact between citizens and representatives. The second aim concerns the reasons why politicians decide to support these means to participationThe empirical material consists mainly of semi structured interviews with local politicians, civil servants, participating citizens and local press. Official documents such as public minutes are also used in the process of creating an image of local participation.Local political participation is found to be limited but yet having the potential to strengthen democracy, provided that public decision-makers are open to a dialogue with the participants.Using Kjell Arne Røvik's theories of organisational change, the changes in local democracy can be explained as being partly rational, partly symbolic and partly identity shaping political decisions..
