En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller
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.
Bestämmelsen om utvidgat förverkande och dess gränser
Abstract Many researchers in social work believe that in today's society require the interaction between organisations takes place on social problems. This study examined the interaction between the police, social services and schools.The purpose of this study are as follows; the aim is to investigate the interaction between social services, the police and schools about young people aged 12-18 years who are at risk for abuse and crime.My questions are: How do the different professions interact regarding young people at risk for abuse and crime? How do they meet young people in their daily work? What obstacles can the different professions see in interaction? What effects do the different professions see in interaction?The study is a qualitative study conducted with semi-structured interviews. Respondents have been two from each organisation.The theory used in the analysis of empirical data is new-institutionalismen. New-institutionalism is a theory developed from organizational theories.
Fonders avkastning -en variabelanalys av fonders avkastning under ekonomisk upp- och nedgång
Vårt syfte är att ta reda på mer om vad som påverkar fonders avkastning och om detta skiljer sig åt i ekonomisk uppgångs- respektive nedgångsperiod. För att uppfylla vårt syfte har vi använt oss av regressionsanalyser med avkastning som beroendevariabel och variablerna: standardavvikelse, beta, storlek, TKA och omsättningshastighet som förklarande variabler. Vi har använt portföljvalsteori med dess ingående variabler avkastning och risk. Även begrepp som CAPM och beta gås igenom. Detta följs av det aktuella forskningsläget inom ämnet.

A further aim was to identify predictive risk factors for falls. Design: A cross-section study with a descriptive, comparative and correlative design based on a questionnaire was used. Participants: The participants were recruited from Uppsala and Västmanlands county. A random selection on 525 individuals was done, from a population based sample, in the detailed municipalities.
Ledarskap inom ramen för ett systemutvecklingsprojekt : fokus på en arbetsprocess med stöd i Vattenfallsmodellen
Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.
Analys av parathormon och joniserat kalcium i blod hos hund :
The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.
"Världens bästa reklamfilm" : En studie i hur reklamfilmerna från ICA är konstruerade för att locka kunderna till konsumtion
This paper sets out to investigate how companies can create advertisement that focus not only on selling but also on entertainment. The research is based on seven TV-commercials produced by the Swedish food chain ICA. The commercials were analyzed according to the methods of discourse analysis, semiotic analysis and rhetorical analysis. Furthermore, the research compares the analysis made with the thoughts and ideas of Tobias Karlsson, Head of marketing and communications development at ICA to find out how the comprehension of the commercials correlate with the original intentions made by the company.The study shows that ICA creates a commercial that contains the perfect mix of rhetorical approaches, communication strategies and entertainment mixed with gravity. The study also shows that ICA fails with its primary goal which is to sell selected products; however, by producing the entertaining commercials, they manage to strengthen their brand.
Hälsa och hälsorelaterat beteende : En undersökning av beteendets betydelse för den självskattade allmänna hälsan
An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.

Systematisk risk och avkastning på en volatil samt stabil marknad : En undersökning på den svenska aktiemarknaden
Background: Since the early 60?s, the CAPM or Capital Asset Pricing Model, has been an invaluable tool for assessing an asset's expected return, assuming that the asset is added to an already well-diversified portfolio of assets. CAPM theory assume that the unsystematic risk can be diversified and that the systematic, market-specific, risk is determined by the Beta value, from the Greek ?. An investor who takes big risks expect higher returns.One of the CAPM?s basic assumptions is that disruption in the market is not taken into account.

ADHD som meningsskapande diskurs : om ADHD i socialt arbete i kriminalvården
The aim of this study is to discuss the diagnosis ADHD as a meaning-making discourse that is something more than just a diagnosis with a set of symptoms. I aim to discuss that the diagnosis is productive and can be seen as a means to control and to comfort individuals.
