This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

The aim of this essay is to examine the ambivalence that I consider work of solidarity carried out from majority position to be associated with, and whether it makes sense to understand the relationship between majorities and minorities involved in this work by using the concepts of race and whiteness. Through Ruth Frankenbergs work on white women and race I consider whiteness to be a racialized position, and through Sara Ahmeds phenomenology of whiteness, which describes racialization as made through the orientation of bodies, I investigate how this racialized position is shaped and maintained by the solidarity work. The study is based on qualitative interviews with four White women engaged in two organizations that works on integration of female immigrants through creating jobs in a cooperative and through educating in national and familial democracy. The work of solidarity told of by the interviewees seems to produce racialized notions about immigrated people of color, which acts as a counterpart to the whiteness that the interviewees themselves possess. At the same time, the work also challenge this binary division, especially by incorporating the non-white women in what in this essay is called "the white world"..

The purpose with this study is to inquire how a number of active preschool teachers use music in their Daily work with children. It also looks at the meaning they think music can have to the whole group of children, especially in terms of solidarity and interaction in the group. In order to study this I chose to use questionnaires as the method. These questionnaires consisted of open questions to enable longer answers from de participants in an effort to hear their thoughts and get their point of view. The result of this study shows that all of the participants seem to have good experiences from musical activities with the preschool children.

During my one year master in pedagogic science, I was frequently given the impression that depicts the pedagogue?s profession as a rather transcendent talent or, more precisely, a matter of having ?it? or not. It seemed to me, as if the communicative part of the teacher?s specialised skill was more or less undefined in the description of what makes the pedagogue a professional pedagogue. On those premisses, I was led to the aim of this study, which is pursuing the very essence of the profession by discussing how five teachers validate their Daily work from a habermasian perspective on communication, society and pedagogy.

The Swedish system of environmental quality objectives is a so-called MBO, Management By Objective and has the purpose to guide the Swedish society towards sustainable ecological development. The system involves the whole society from the parliament and the government down to individual citizens. At the regional level, it is the county administrative boards that are responsible for the work with the system of environmental objectives. At the County Administrative Board of Västmanland County, it is the environmental unit who is in charge of work with the environmental objectives and they want input for how to improve their work with the environmental objectives, both internally at the Administrative Board and externally with external parties.The main purpose and goal of the study is to present the work of four other county administrative boards regarding their work with the environmental quality objectives and to identify external parties? opinions of how they want the County Board of Västmanland county to work with them in this matter.The work is designed as a case study of four county councils, where the environmental objectives coordinators at the four county administrative boards were interviewed about their work with environmental quality objectives.

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

The purpose of this study is to investigate whether the employability of newly graduated social workers is affected by the Supervised Practical Work Experience performed during the educational program. Four main questions were developed in order to establish an educated and concise theory: Does the newly graduated social worker?s choice of a specific Supervised Practical Work Experience affect their employability? Does the structure of the Supervised Practical Work Experience affect newly graduated social worker?s employability? What specific skills do employers within social work consider important for their organization? Is there a difference in how the representatives of various organizations within social work answer the aforementioned questions? The study was conducted through six qualitative semi-structured interviews. The people being interviewed work either as employers or recruiters in organizations from different areas within social work. Theories concerning organization and symbolic interactions were used during the analysis of the results.

This report shows a qualitative study on how six young adults in the ages between 20-30 who are students at Linnaeus University in Kalmar percieve their news consumption habits and their use of news media on digital platforms. The aim of the study is to examine whether the six students feel the strogest connection with the press where they were raised or where they currently live, why they choose to use the media platforms they do and what meaning the use of the media bare to the students. We have seen a lack of information concerning why young people choose to consume news online instead of in printed media.The study is focused on theories concerning what affects people in their choice of media platforms and channels. This report shows that geographic nature, the quality of the content and which political ideology the daily press is founded on does not affect the respondents choice of media. Our study shows that the most important factor for the respondents is that the platform is easily accesssible and flexible.

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their Daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

The purpose of this study was to investigate to what extent  young adults use media to create the image of themselves. The questions we wanted to answer was as follows: what does the media use of young adults look like compared to their attitudes towards media content; what awareness do they have of other young adults attitudes concerning media content; and finally, how do these attitudes affect their own media use?Media consumption is a great part of  the daily lives of young adults living in Sweden: the national  average media consumption is seven hours a day, for 15-24 year olds. This provides a new way for young adults to express their identity - by showing their use of different media content, they can change other's perception of themselves.The method we used in our study was a combination between a quantitative and a qualitative method. We first made a survey in three classes with senior year high school-students, in a Swedish school.
