This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

The aim with this study was to learn about the experiences of field workers and welfare officers in the field of possible self-harm behavior among young people.Our problem was: Do field workers and welfare officers treat young people with deliberate self-harm differently and - How do field workers and welfare officers describe deliberate self- harm?Our study was conducted through qualitative semistructured interviews with twelve interviewee?s.The result of this study shows that there is a difference in how young people with self-harm behavior are being treated - based on their gender.One possible cause for this result could be the old tradition mindset of viewing boys and girls differently ? and thus, treating them differently when they seek help.Our study shows there is a possibility of treating boys and girls differently ? which shows that we made a thought-provoking point.

Genom litteraturstudier samt praktiskt arbete med förbättringar av programvaran File Secure har ett antal lämpliga designmönster för konfigurationshantering i Java identifierats och applicerats. Den typ av konfigurationshantering som här avses innefattar inläsning från en databas till en objektrepresentation, samt ett grafiskt gränssnitt som låter användaren modifiera datat. Det antas att mängden data är förhållandevis liten, vilket har gett upphov till vissa förenklingar. Resultatet av arbetet presenteras i form av ett mönsterspråk för konfigurationshantering, innefattande designmönstren Domain Model, Active Record och det befintliga mönsterspråket Model - View - Controller. Detta kan appliceras i många olika sorters system..

Syftet med denna studie är att undersöka om det finns ett samband mellan opredicerbara föräldrar och förekomsten av både interna och externa beteendeproblem hos ungdomar. I studien undersöks interna beteendeproblem såsom låg självkänsla och depression samt de externa beteendeproblemen brottslighet och aggression. Studien baseras på 1018 ungdomar i åldrarna 13- 15 år. Studien utgår från en enkätundersökning där fem olika skalor används för att mäta ungdomarnas självkänsla, depression, brottslighet och aggression samt hur konsekventa deras föräldrar är. Resultaten visar i allt väsentligt att de ungdomar som har både interna och externa beteendeproblem är de som rapporterar högst i opredicerbarhet hos sina föräldrar..

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

AbstractThe purpose of this study is to explore the organizational culture within the corporation The Body Shop. I have been working with two different question formulations. The first is to answer how the culture can be described. To answer this I have been using Edgar H. Scheins theory of cultural levels.

Due to the forest industry downsizing, many communities in rural forest regions in Canada and Sweden are facing problems to survive. In order to create community sustainability, resilience and well-being in remote forest regions, the view on the forest resources has shifted towards multiple use, through the concept of sustainable forest management (SFM). Beside the economic and ecological elements of sustainability, the social forest values are needed, contributing to the human well-being, local participation, stakeholder collaboration, human rights and cultural connection. In this thesis the embodiment of the social component of SFM within Prince Albert Model Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners and facing similar challenges as rural boreal forest regions, the two model forests are compared through analysis of projects and activities, conducted interviews and organization documents. Looking at projects mentioned as successful by the interviewees, they all have elements from the social values of SFM. The direction can be explained by the introduction of the Forest Communities Program in Canada, demanding the Model Forests to work towards community stability and resilience, the Model Forest organization concept itself and the way global focus are increasing around social forest values. In the future, it may be important that the role of the MFs enable some kind of political authorization and legitimacy in order to improve conflict solving and indigenous rights equality.

Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

There are many kinds of joint operations and combinations of combined arms. This thesis puts its focus on Close Air Support, CAS. Throughout history there have been several cases of success, regarding these kinds of operations, but also failure. Much can be taught from organizational behaviour studies, applied on these military organisations in their cooperation with each other. The purpose of this thesis is to analyze the cooperation between the Swedish army and air force to determine the functionality of their process.

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

Artificiella ekosystem är en tillämpning av artificiell intelligens som har funnits länge. Användningsområden för artificiella ekosystem innefattar främst biologiska simulationer men även andra typer av simulationer förekommer. Genom att simulera individuella djur blir den artificiella intelligensens uppgift att styra djurens beslut utifrån dess individuella förutsättningar och kamp för överlevnad. Detta arbete behandlar frågeställningen vilken beslutsalgoritm som är bäst lämpad att för att använda till ett artificiellt ekosystem i ett spel. Två beslutsalgoritmer jämförs, en dynamisk som bygger på maskin inlärning och en statisk som inte är kapabel att lära eller minnas.

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

In the thesis we have shown that it is possible with current technology, to buildneighborhoods that are largely self-sufficient. We have obtained some information aboutongoing work in the field of energy efficient buildings and active house which we have usedto develop a model. The feasibility study for Ranagård we have e.g been forced tofollow laws on groundwater covered, resulting in the construction of basements for singlefamilyhome is not possible. The model that we have built up overtime has been the central part of the work. The model illustrates very well what an activehouse neighborhood means and potential of such an area.

The purpose of this paper has been to examine the ways in which professionals describe their work with pregnant drug-addicts. The paper raises the following questions;· How does the deviant behavior, that using drugs during pregnancy can be described as, affect the professionals in their work with pregnant drug-addicts?· How do the professionals experience their own role, and the roles of other professionals?· In what ways do they work in order to reach a favorable result with these clients?The paper is based on qualitative material, gathered through 14 interviews with professionals. By using theories of deviant behavior and attachment-theory between a child and its mother, our intention was to analyze the empirical results.From our interviews we have learned that the professionals consider some factors as more important than others for a favourable result in their work with pregnant drug-addicts. Such factors are for example the significance of a cooperation between different authorities and ethical awareness in meeting with the client..
