The credit rating industry is a complex and fascinating industry. Its history stretches back more than 150 years and has gradually increased in importance. During its history the dynamics of the industry have changed. The extended-principal-agent model was developed by synthesizing different principal-agent-relationships into one model. This model provides a holistic understanding of the credit rating industry and illustrates the interdependence between the different relationships.

After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.

The construction industry accounted for 19 % of all work-related fatalities in Sweden between 2010 and 2013. The exam report has been done to find out what underlying causes there are to the high number of fatalities and to the occupational statistics of the construction industry. Moreover it has been reviewed what improvements can be done to reduce accidents and fatalities in the construction industry. The report consists of a survey of statistics, laws and regulations affecting the work environment and of literature concerning the subject. It has been conducted an interview and a questionnaire survey at the construction company Asplunds Bygg and an interview with an inspector from the Work Environment Authority.

Calculations of net present value are based on a discount rate, which requires knowledge about the company?s cost of debt. A common way to do this is by observing the company?s credit rating, when no credit rating is given it?s possible to use a synthetic rating model based on quantitative data to estimate a credit rating. Thus, the aim of this study is to increase the understanding of which quantitative data, in terms of key figures, that can be used to explain the given credit ratings for companies from the Nordic countries.In developing the model, key figures found significant in previous studies are being tested for whether or not they are applicable for companies from the Nordic countries.

AimThe purpose of this study has been to help Åtvidabergs FF to find development opportunities by reviewing the internal communication and decision making process within the organization. In this study we have used two models, Johari window and Administrative man.Our study has two main questions. The questions at issues are:? Can Åtvidabergs FF with help of the communication model Johari window identify how the internal communication can improve?? Can Åtvidabergs FF use the Administrative man as a decision model?o Will the use of the model Administrative man lead to better decisions will be made?MethodWe have made a qualitative case study in a positivistic spirit. Data has been collected through half structured interviews.

Sexual dysfunctions concerning women with multiple sclerosis (MS) are common. Since the disease preferably affects young individuals when establishment of family occurs, the result of these problems have a great impact on the individual and her family. The purpose of this literature review is to throw light upon these problems and respond the questions if the nurse may be the right person to give sexual counselling and in which way this may be done. The theoretical framework was Antonovsky´s concept "sense of coherence". The result is presented in four themes: bodily aspects, social aspects, information/counselling, and practical implications for nurses.

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

Aim: The aim is to create a review that examines different forms of massage therapy and their effects on hypertension.Method: Literature review of 10 scientific articles on the subject of massage and its effects on blood pressure. The literature searches were made with PubMed and Cinahl using the keywords "massage therapy", "effects" and "blood pressure".Results: The articles showed that massage had a positive effect in lowering blood pressure. This could be explained by greater extent of relaxation in the participants investigated and an increased activity of parasympaticus and reduced secretion of stress hormones. The articles do not agree on what form of massage therapy is most effective in lowering blood pressure and it is uncertain for how long the effect can remain.Conclusion: Massage is usually seen as a treatment without scientific basis. There is evidence that suggests that massage therapy is an effective treatment for lowering blood pressure.

Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.

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.

This essay examines teaching in source criticism in upper secondary school history education. Two questions are to be answered: 1. What are the conditions like for teaching source criticism? 2. What opportunities for further development in teaching source criticism are there? In order to set a standard for what knowledge and skills in source criticism the students need, I design a four step model for good source criticism based on the historical science.

The society of suburbs is frequently discussed in media, which often focus on the problems related to these areas. The purpose of this Master?s thesis is to examine how Swedish contemporary youth literature may contribute to create, strengthen and articulate social representations of the society of suburbs. The analysis is based upon six youth novels published during 2003 to 2007. The theoretical framework consists of two parts and is based on Anthony Giddens? theories about late modern society in which the youth novels in our study take place, and those living conditions that this society creates.

It is important to ensure and develop the Swedish model for riding schools, since the pupils at a Swedish riding school learn both to ride and to handle horses. There is a pronounced problem of stagnation and in some cases a reduced demand in several of the equine industry sectors including breeding with decreased coverings. The aim of this study was to cast light on how representatives from the horse industry looks at riding schools and their recruitment of horses in the next five years. The research issue was ?Will there be difficulties regarding horse recruitment in 2020 and in that case, what are the consequences?? The results of this work consist mostly of material from a workshop on how the riding school will be affected by reduced breeding in the future.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
