Utmattningsdepression : En studie om det moderna arbetslivets relation till psykisk ohälsa utifrån fem kvalitativa intervjuer
The purpose of this essay is to try to understand the relationship between the structures of modern working life and the development of burnout. By using the method of qualitative interviews we wanted to see if the Effort-Reward Imbalance Model could be applied to the data we had collected. Two questions have been highlighted in our research: ? Is it possible to establish a relationship between the structures of modern working life and the development of burnout among the subjects interviewed? ? Is it possible to explain the development of burnout among our interviewed subjects through the Effort-Reward Imbalance Model? Our theoretical frames are the general theories of the modern society and the modern working life as developed by Anthony Giddens, Ulrich Beck and Zygmunt Bauman. We have also used Johannes Siegrist?s medical-sociological Effort-Reward Imbalance Model (ERI-Model).
Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
Analys av QoS i mellanvaran Meteor
This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.
Religionskunskapsämnet i förändring : en historisk exposé samt nutida jämförelser
AbstractThe purpose with this essay is to present a picture of the changes in religious education in Sweden, and to make comparisons between Denmark?s and the USA?s model about teaching in religion. I have consequently described the historical development, with the beginning of the establishement of the public school, inte the year of 1842. 1919, a new document about the religious education was released, wich result in some major changes. This was in a time were the debate about religion and the Lutheran State Church of Sweden authority was an issue.
Problemet med Sverigedemokraterna : En studie i hur Sverigedemokraterna representeras i två svenska tidningar
The aim of this study was to examine how the political party Sweden Democrats is represented in two Swedish newspapers. The study included a national newspaper and a local newspaper, Aftonbladet and Blekinge Läns Tidning. We studied 35 articles from both papers, from 2005 and from 2009. We analyzed the texts using the linguist Norman Faircloughs (1995) method for discourse analysis. Based on his theories, we created our own model to examine the texts. Our model primarily focused on representation. The study was conducted at a time when Sweden Democrats was given much support in opinion polls and knocked on the door to the Swedish Parliament. The study showed that Sweden Democrats in both newspapers, primarily by descriptions, the choice of interviewees, etc., often are represented as racists.
Modell för idéutveckling
The purpose of this report is to create and develop a model that streamlines and helps the innovationprocess of an idea owner and also in the development of ideas.This model should be able to apply for workshops and in innovation advice or business devlopment. I used the qualitative method in my essay just to get a maximum clear data collection, where the seven respondents were included in the interviews. However, much of the information retrieved from the theory books and research/science articles, in order to answer the research/Sceince question in the best possible way.
En meningsfull fritid : En kvalitativ studie om fritidspedagogers uppfattningar av begreppet en meningsfull fritid och den egna yrkesrollen
The purpose of this study is to explore active after-school teacher?s perceptions of the concept of meaningful leisure time. The purpose of the study is also to investigate if the interpretations of meaningful leisure time affect the perception of their work roles and after-school teacher?s actual work in a leisure activity. The study also provides an insight into how afterschool teachers perceive their roles in general.
En jämförelse av beteende mellan vävande hästar och två icke vävande hästar under liknande förhållanden :
Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable.
Seven weaving horses were included in the study.
Kvalitet i fritidshem : En studie om pedagogers tankar kring kvalitet på en skolas fritidshem
The study aims to contribute knowledge about children's perceptions of the leisure-time as a learning environment. The study can be seen as an attempt to highlight the possible learning in the leisure-time, formally or informally.The study is based on two group interviews with a total of 11 children and was conducted by an interview guide with question areas to be discussed freely so that the children could give as full an answer as possible.Main results of the study show that children feel that they are staying at the leisure-time to get care when their parents are working and that they primarily associate the leisure-time with playing. The results show however that children feel that they learn things when participating in the leisure-time teaches controlled activities.It is possible to draw conclusions about the child actually experienced the leisure-time as a learning environment, but it can be difficult to identify when and how learning actually occurs. However, children do not perceive that there is learning while they play..
Digitizing the Parthenon using 3D Scanning : Managing Huge Datasets
Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.
Public Service Begreppets olika ideal och tolkningar
With this master thesis we wanted to find out in which way the concept of public service is connected to different perspectives, ideals, visions of the future and forms of organizations. The purpose with our thesis was to do an analysis of different concepts regarding to public service. To the analysis of concepts we used Swedish newspapers and analysed the issue of public service that had been discussed in articles written during the last five years. From this material and other papers about public service we developed a model of public service ideals. We wanted to find out what the different perspectives thought about the Swedish television and their commission.
Klassificering och värdering av finansiella instrument : Ett tillförlitlighetsperspektiv
During the financial crisis voices were raised towards the regulatory framework IAS 39 recognition and measurement of financial instruments and pointed out that it was inadequate. The complexity of the framework contributed to the fact that it was difficult to apply. IASB accelerated the modeling of the new to be regulatory framework IFRS 9. In this study we will focus on the reliability of accounting information, which is an important aspect from the stakeholder?s point of view, for example, to be able to make the best decisions the accounting information should be proper.
Från Lev Tolstoj till Joe Wright : En adaptionsstudie av Anna Karenina
This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.
Att identifiera signaler för obestånd i tid
To be able to protect themselves from credit risk, the banks must constantly check the performance of the companies they have lent money to. There are many mathematical models for predicting financial distress. These models use accounting-based ratios, which often are historical and not representative for the present situation. This study describes how the banks do in practice to find signals of insolvency in time and the variables they are observing for doing that.In addition to financial reports which the company sends in to the bank at least once a year, also the relationship between them and information from different information agencies are of great importance to track signals of insolvency. Poor profitability is the primary cause of insolvency.
Time & Sväng i sång
Syftet med studien är att få djupare insikt i sångpedagogers syn på Time och Sväng samt hur de didaktiskt arbetar med dessa aspekter. Det saknas mer omfattande forskning inom området. Med detta i behåll har jag för avsikt att få djupare insikt i frågeställningar som rör olika förhållningssätt till hur sångare kan öva upp Time och Sväng samt vad Time och Sväng innebär, generellt och i ett undervisningsperspektiv. Studien har som sin teoretiska utgångspunkt ett sociokulturellt perspektiv med fokus på hur människor använder olika redskap för att kommunicera med sin omgivning.För att få svar på mina frågor har använt mig av en halvstrukturerad intervjuform när jag samtalat med informanterna. Alla informanter i denna studie arbetar idag som sångpedagoger; två av dessa är mer inriktade på jazz medan de andra två är mer inriktade på populärmusik.
