ABSTRACTBackground: Children and adolescents growing up in families where parents have serious problems are exposed to an increased risk of developing poor mental or physical health themselves. In a support group work they can meet other children in the same situation, receive help and support to process their emotions and manage their everyday life.Aim: To investigate if support group work at Trappan can reduce the psychological problems load and increase the experience of life quality, hopefulness and optimism in children and adolescents growing up in families where either addiction or mental illness occur in one of the parents. The purpose was also to investigate if there was any difference between these both child groups regarding psychological problems load, experience of life quality, hopefulness and optimism before and after support group participation.Method: Questionnaire study on children and adolescents of parents with addiction or mental illness. The children participated in support group work at Trappan. The measuring?s were conducted before and after support group participation.Results: In both groups an increased life quality in connection to finished support group participation was observed.

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

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.

Body esteem is the affective aspect of body image, which is shaped by social experience. Compared with men, women have a more negative body image, which is more frequently correlated with depression and dysfunctional thoughts, especially in the case of eating disorders. The purpose of the present study was to examine gender differences in body esteem and its subcategories, and to find out whether there exists a stronger link between negative body esteem and higher levels of dysfunctional thoughts in women. The relationship between body esteem, dysfunctional thoughts and mental illness was examined. Participants were 73 college students doing social sciences and sports training educations.

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.

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 focuses on young adults with mild mental retardation and how their early adult life is a few years after leaving high school. They have grown up in a society where the view on mentally disabled has undergone big changes. Political decisions regarding handicapped, laws, official principles and social reforms have been dominated by the prinziple of normalization.The purpose has been to describe how the young adults themselves experience their life. The questions were: How is the every day life for young adults with mild mental retardation? Do they have asset to community support in order to reach as normal life as possible? How satisfied are they with their life?The investigation is a quality study through interviews with four young adults and their parents.

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 is a qualitative study based on interviews with professionals who are cooperating at a children advocacy center, in swedish called ?Barnahus?. The center, Barnahus, pulls together law enforcement, criminal justice, child protective service, medical and mental health workers in to one coordinated team. Children suspected to be victims of any kind of violence or sexual abuse shall, at Barnahus, be offered coordinated efforts and support all the way from suspicion to possible intervention. The aim of the study is to examine how the participants involved relate to collaboration in Barnahus. The study will also present the success factors and barriers to collaboration that identifies by the participating actors, who are mentioned above.The study will provide insight and understanding of how collaboration can be represented in multiprofessional activities in practice..

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.

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.
