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.

The purpose of this study is to examine whether there are any key factors for success to look for in launching a new business that affects the subsequent performance of the venture. Further on, the study will examine if there are any differences between believed and actual factors for success for an entrepreneur and the key factors for success given by existing theory. The purpose of looking in to the assumed gap between existing theory and entrepreneurs? believed and actual factors is to distinguish factors that make start-ups evolve. It is then important to investigate how they have worked with their business start-up and how they have worked with key factors for success in order to understand the impacts of their decisions.

Purpose: The purpose of this thesis is to examine whether some periods of declines in Swedish real credit can be explained by a credit crunch. Is it further possible, with these results, to do any conclusions about the banks behaviour in the on going financial crisis that has shadowed the country since 2007/2008? Method: A credit crunch is here defined as a period of supply-side restrictions on loans which doesn?t reflect the ongoing interest rates. By estimating a supply and demand function with a disequilibrium model the excess demand- and supply for credit due to different periods can be calculated. Conclusion: A credit crunch has been present during a period after the banking crisis of early 1990?s.

The executives of a firm possess considerable influence over a company's financial reports. The numbers can be adjusted in a favorable direction by engaging in Earnings Management, which harms the reliability of the financial reporting. Previous research suggests that Earnings Management can differ between genders. In recent years the debate about a woman's role in the business world has received generous attention in media. Moreover, the presence of women in leading positions has become a relevant issue for firms.

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

Objective: The papers objective is to create a deeper understanding for whether or not cultural and psychic distance affects corporate establishments in the EU.Method: The results have been gathered through intense data collection through interviews with ScaniaAB and Business Sweden. There has also been extensive research of 36 different companies and their first establishments in different countries. We have then analyzed the results through cultural and psychic distance and through Uppsala University's internationalization process model.Conclusion: The conclusions of this paper are:Corporate establishment often occurs in neighboring countries because of the similarity to the domestic markets which contribute with a greater security.Since the introduction of the EU single market, corporate establishments have become easier within the single market.The cultural and psychic distance does exist within the EU, however the internal market decreases these distances and the impact on corporate establishments.The market commitment is essential to the corporates survival within the new market.Cultural and psychic distance affects small firms more often since their lack of network and experience.Cultural and psychic distances are two different but related phenomena..

Background: The development of the Swedish demography is one of the most important social and economic changes ever in Swedish history. Society as well as business is facing an age chock since almost every other company owner is over 50 years old. The complexity of managing a successful succession is pointed out as a major threat to the Swedish economy by the organization Svenskt Näringsliv.Purpose: The purpose with this master thesis is to identify and analyze critical success factors for a successful succession from a going concern perspective.Research method: By using the strong aspects from the quantitative as well as the qualitative method, high level of order and systematic could be reached, without loosing too much details and depth in this particular research. The empirical data was gathered by a digital survey sent to 3000 companies. The quantitative research was complemented by 6 qualitative interviews to increase depth and reliability.Results: The study shows that there is a great incongruence between the expected problems associated to the succession and the actual outcome.

The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish Riksbank use. The difference between my analyse and theirs is that we use different periods..

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 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).

This study aims to investigate how value is constructed in horse business, in order to increase knowledge and contribute to development of theory in this field. This is important since the horse plays a significant role in the rural development in Sweden. The study assumes that value is something created through relationships in the social network. Therefore theories of sensemaking are combined with a discourse analytic method. By interviewing customers to two companies, one with orientation on trotting horses and one with orientation on showjumping horses, it was found that value is constructed through retrospective stories.

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.

Outsourcing, förflyttning av funktioner till extern part som tidigare funnits i företaget, är ett fenomen som under de två senaste årtiondena har vuxit starkt i världen. Outsourcing har möjliggjort för företag att fokusera på sin kärnverksamhet och därmed erhålla konkurrensfördelar. Business Process Outsourcing är en kategori inom detta område, som innebär att företaget outsourcar hela eller delar av sin ekonomifunktion. Användandet av Business Process Outsourcing har ökat bland de svenska företagen under de senaste åren. Det finns mångtydiga förklaringar till denna framväxt, där en förklaring är att det är en trend.

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
