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.
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.
The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems
Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.
Buzz : Med individen som insats
abstract buzz marketing, the phenomena Have you ever thought about why the small French pastries called macarons suddenly became so extremely popular? Soon they were seen everywhere in the media, on every celebrity party and shortly after of course on every Swedish person?s cake dish. Could it be that a trendy it-girl happened to mention these lovely creations in her blog?What (or who) is it really that decides and controls what is popular and what is going to sell? If one individual can influence a whole group of followers it is definitely something marketers should take advantage of. One cannot any longer rely on traditional advertising, one needs to be more creative and rethink the possibilities to get through the media noise.

Additionally we compared various categories such as gender and age to discover any patterns within the groups.There is a clear conflict in the answers given by the group we studied, between the desire to have access to all the information and experiences Internet has to offer and the desire to protect youth from inappropriate content and/or influences from unknown sources.

Livet på gamla dar': en kvalitativ studie kring äldre personers livskvalitet.
The aim with our paper has been to get a picture of which factors one of the heterogeneous group that we've chosen of old persons, 75-90 years, in Scania, in south Sweden, have experienced to be of importance for their life quality today and what they wish to preserve of their actual life style when they eventually shall use the elderly care. Also how their individual life course has influenced their experience of the quality of life.We found this subject interesting as the group of old people in the society is constantly increasing and when the group becomes bigger, then greater demands will be put on the elderly care. We have proceeded from a standpoint that all people are unique individuals and that people become what they are from their life histories and from the choices they have made during their life. We have used the life course theory that says that one should see the individual in his/her wholeness and the whole life history of a person in order to understand him/her. We have also studied earlier research concerning the different determinants of the life quality.
