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.

Today automatic milking systems (AMS) are growing in popularity. In these systems the cows are loose and have to get to the robot and the feed on their own. The cows ranking in this system affect their welfare. In this study data from seven years in an AMS was used and analysed. The aim was to investigate how ranking could affect the behaviour of the cows at milking and at feeding.

In the beginning of the nineties there was a change in how the voluntary sector was perceived, and the significance of their work became reevaluated and more acknowledged. As a result, this sector gained a new and higher interest. The changes and downsizing in the welfare state with economic crises, due to political cutback, made the politicians look fore new solutions. One solution is to encourage cooperation between the public sector and the voluntary sector in order to handle the different needs of individuals.Uppsala community and the voluntary sector are working closely together within a project called ?God Livsmiljö?.

Psittacines and reptiles are exotic animals that are difficult to care for and it requires extra knowledge to make a correct assessment of their wellbeing. An animal welfare inspector, with an education in general animal welfare, may not have a deep enough knowledge of exotic animals to do a proper assessment of the animal?s general condition and its environment. In this paper it was therefore examined if animal welfare inspectors have enough knowledge to do a satisfying inspection of establishments working with selling of exotic animals. A literature study was used to examine difficulties with each species.

Organisation and market orientation of elderly careThis comparative literature study is intended to describe how elderly care is organised and financed in Germany and Sweden. Furthermore, it analyses the degree of competition and market orientation in both countries' care systems. Important aspects in this context are the kinds of measurements which are used on the two markets and the question if there are quasimarkets.The theoretical backgrounds of the study are Esping-Andersen's "Three Worlds of Welfare Capitalism" and Harold Wilensky's convergence theory. Esping-Andersen's theory describes Sweden as a social democratic and Germany as a conservative welfare regime which means that there are different conditions for the development of welfare. The use of Wilensky's theory shows that both welfare systems are converging since the end of the 20th century.

This thesis studies the way valuation of investment properties is conducted in accordance with IAS 40 and how reliable these valuations are. This has been conducted by studying ten Swedish real estate companies listed on the NASDAQ OMX, during the period 2005-2008. The study shows that all companies use valuation models to determine the fair value of investment properties. Two different types of models have been identified. Companies that use the cash flow model show inconsistencies in time horizon, and how they determine the horizon value.

Organic animal husbandry has received a lot of criticism lately. The aim of this literature review was to examine if the rules and principles of organic pig farming give better or worse welfare in comparison to the conventional systems in Sweden. Health, physiology and behaviour have been used as indicators of welfare in this study. This is due to the importance of using more than one indicator in welfare assessments. Studies have shown that organic pigs have more remarks on joints when slaughtered, but these remarks can be reduced by vaccination against erysipelas.

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

In the beginning of the twentieth century in Sweden the laboring class grew and became more established. This entailed both a change in housing conditions and the design of the social policies. The purpose of this study is to show how the Child Welfare Committee in Kalmar conducted its work during 1911-1918. The aim is to show on what grounds they made their decisions and how the interaction between the committee and the families functioned in practice. This will be accomplished by giving examples from the protocols written by Kalmar?s Child Welfare Committee.

How do you do co-operation between government agencies? It is a wide spread view that there can be quite a few hitches in co-operation between agencies. In later years this idea has spread to the media where there has been negative coverage of the social service agencies. This generally applies to cases where children suffer because the right assistance takes too long to co-ordinate or does not get co-ordinated at all between schools, healthcare and social services. The social welfare law dictates that it is the social welfare office duty to co-ordinate the government agencies for the child?s best interest.

Stressful routines for animal handling can reduce immune function and productivity of animals. If stakeholders are handling animals aversively, animals will show increased expressions of fear for humans and higher stress levels which lead to the compromise of animals? welfare. In Ethiopia, there are no legislations to protect animals from suffering or discomfort. The main objective of this study was therefore to analyse welfare of cattle on animal markets in Ethiopia and map out supply chains of animals to these markets.

The purpose of the paper is through a touristic view to see how the zoos have developed to modern zoss and interview Djurens Rätt and Skansen to see their view on "animal welfare". Another part of the paper is to see what the public thinks of animal welfare and if it's crucial when they choose a destination. We used a survey to see if the public has been influenced by any media in the aspect of their view of zoos. By seeing the evolution of zoos to the modern zoo, we can see how society had the power to influence. .

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

The focus of this thesis is on social workers? knowledge in assessing and making decisions in child welfare cases. The primary aim is to identify what skills or knowledge social workers find most useful within child welfare agencies in Swedish municipalities. Six different types of knowledge, social policy and the approach of child welfare cases are perspectives considered in the analysis. The interviews with social workers were held in three agencies in southern Sweden, in 2014.
