Large companies in today?s business environment are to a great extent depending on their credit score by rating institutes like Moody?s and Standard & Poor?s. There is however indications that these big institutes are not always rating companies accurately. This is why this thesis aims at developing a new credit rating model, CRITA-Score, with the objective of determining a company?s financial health more accurately.

The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).

Nordic Marine Sauna AB has, since 2005, designed, manufactured and sold floating saunas. Theproduct are characterised by a well thought thru and appealing design and its high quality. Thecompany is now intending to open a new business area by starting a subsidiary, NordicSubmarine Sauna AB, which will design submerged saunas. The expected customers are leisureand conference centres as well as customers that seek an experience out of the ordinary.Due to the products technical complexity a master thesis was adverted. The task was to do aninvestigation whether such a product is technically viable.The job involved research of existing products and constructions material as well as designingthe product with CAD and FEM-programs.

This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.

The aim of our thesis was to describe how the connection between co-dependent relatives and the alcohol-dependent influences the family into changes in their teamwork.Our purpose was also to answer the following questions: How is it living with an alcoholic? Are there any differences in how men and women feel and behave in their relationship with an alcoholic? Are factors like cultural belonging, genre or social class important for how the co-dependent relatives feels and behaves and handle their co-dependency?To answer these questions we made twelve thematic qualitative interviews with six adult children to alcoholics and six people married to alcoholics. We compared the results of these interviews with earlier research. We also applied System Theory and Goffman's Role Theory, as well as Bourdieu´s Capital and Habitus concept.We believe that co-dependency is a family divergence that is very similar to family disease, but that a change in attitude can trigger recovery. According to the interviews many spouses stand by their alcoholic husbands and do actions that perpetuate the alcoholic dependence and thereby hold back any recovery.

Does the country people live in affect the probability of them experiencing happiness? Can a country variable in an ordinal regression model be affected when microeconomic and macroeconomic factors are added to the model? The possible outcomes are either that the country variable affects less when the additional predictors are added to the model, or that they stay the same. The micro data is collected from the European Social Survey database, the macro data is collected from the World Bank. The country variable becomes less substantial when additional variables are added to the model. The variable with the most influence over expected happiness apart from the country variable is whether the individual often socializes with friends or not.

This study aims to further Work-family conflict research for Social Workers by providing insight into what kind of impact the job role of social workers in Sweden has on their private lives and how they deal with it. The study operates from a qualitative approach and is based on three focus group-interviews and three semi-structured interviews with people working in different fields of social work. The empirical material has been analyzed through the Dramaturgical Perspective and Frame concept of Erving Goffman. The results of this study show that the job role impacts the psychological well-being of social workers, their family life and their social life to varying degrees, mainly due to organizational and client-based aspects, often resulting in role-conflicts and a lack of energy in their private lives. The primary strategies were found to be conversing with colleagues, spending time alone, embracing hobbies and having a clear understanding of individual responsibility. .

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

In the 1960?s, Paul Hersey and Ken Blanchard developed a theory called Situational Leadership. Situational Leadership is a model where the leader analyses the needs of the situation and the needs of the people to be led. After analysing the situation, decision is made on what leadership style to adopt. The Situational Leadership model was developed in a company environment.

This master thesis is looking into the stories on the internet forum www.resedagboken.se. The stories of Swedish teenaged exchange students in the U.S. are studied and the main purpose is to see both what they are writing about and the reason for why they are spending their time writing down their experiences in a public forum.Even though most of the teenagers here are writing with a specific audience in mind, all the stories are free to anyone to take part of and this causes a difficult position for the teenagers who often seem to forget the public point of view when they are telling about their personal lives.The study is divided into two parts. The first one looks into the content of the stories and the other one focuses on the storytellers and their reasons for writing. The teenagers are writing both a lot about their everyday lives in their new environment, but also a lot of things to keep in touch with what their friends and family in Sweden are doing.

The study explored how a model for conversation partner trainingworked for family members of people with Parkinson's disease. Participants inthe study were three dyads consisting of persons with PD and their carers. Thepurpose of the study consisted in finding out whether the participantsexperienced a change in communication after the intervention, and in findingout if this potential change could be observed in the conversation. The resultsshowed that 4/6 participants experienced an improvement in communicationafter the intervention. This improvement was however not observed in theconversation.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

Background: Children in our present society spend more time sedentary, and food has become more accessible. It is important to pay attention to obese children, because of the risk for serious diseases in the future. Obesity can also cause mental suffering for the child. Aim: The aim of this study was to describe the nurse?s care of obese children.

The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.

Since 2003 Saudi Arabia is under attack from domestic Al Qaida-cells which, by random shootings of westerners and bombings of compounds and official state buildings, is trying to challenge the stability of the royal regime. According to Al Qaida, the Royal family is attacked because of their friendly relations to the US and for not implementing Islam in the Saudi society as profound as they ought to. Political analyst finds it obvious that the Islamic Al Qaida-cells by terrorism is trying to erode the stability in the kingdom.An important foundation for stability for any government is legitimacy. The aim of this thesis is to examine the royal legitimacy strategy in the state bureaucracy of Saudi Arabia. The question at issue is: how has the royal family constructed the civil, military and religious bureaucracies to maintain and promote stability and legitimacy?The thesis focuses on the on three different units within these three bureaucracies and it surveys the way they are staffed and organized to strengthen and maintain legitimacy for the royal family.
