The purpose of this paper is to study whether or not stock returns increase abnormally over month ends on the Swedish stock exchange. Previous research has proven an international so called ?Turn-of-the-Month? effect where stock returns increase significantly over a few days around month ends. If the effect exists, it is a violation of Fama?s Efficient Market Hypothesis.

The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological restoration-project in a forest landscape.

Does goodwill affect the cost of capital? Goodwill is an asset which is characterized by much uncertainty regarding both what it is and how much it is really worth. Based on economic theory about information risk and principal-agent problems as well as theory regarding the cost of capital we test for the hypothesis that debt and equity investors perceive goodwill as something risky and hence demand compensation for taking on this extra risk. The proxies used for the cost of capital are cost of debt, beta and the EP-ratio. On a general level we find that increasing the level of goodwill seems to result in higher cost of capital as represented by the three proxies.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Title: A study about the purchasing process of ITLevel: Master thesis in Information Technology and Business Administration, 15 hp, EIK024Authors: Emelie Johanson and Mikael LindströmTutor: Peter Ekman, Mälardalens HögskolaKeywords: IT-investment, purchase, decisionProblem: In the last decades the amount of IT investments increased and has become an important resource within most organizations. IT gives the ability to compete and could also be a condition for many to be able to compete. In different businesses it could vary in where they put their focus when they choose an IT investment. This thesis examines how the purchase process of IT looks. How does processes differs in a bigger company versus a smaller company? From these two perspectives this study examined these research questions: Who makes the decisions whether or not an IT solution should be purchased? What aspects decide when companies are to choose between different IT solutions? Where in the purchase process do problems usually emerge?Purpose: The purpose of this thesis is to describe and analyze the purchasing process of IT from a business perspective.

This study analyses the economic consequences due to ethanol production in Eastern Sweden. The analyses consider the cooperative and the farmers as one vertically integrated company. The area that found the market in this study is illustrated in figure 1. The analyses assume that all members act jointly with the objective of maximizing joint profits at the farm level as well as at the cooperative firm. A mathematical model is created to calculate the optimal use of arable land.

The organisation of the municipalities is based on the principle of representation. It has previously been impossible to give the citizens more influence through direct democracy, but the information technology gives new possibilities and the choice of democracy model might no longer be obvious. Representation can be interpreted in many ways and there is a need for a more distinct definition of the rule that the municipalities shall be governed according to the principle of representation. It should also be further investigated how the new technology can be used to increase the use of direct democracy. The municipalities ought to work to supplement the representation with direct democracy in the form of active discourse with the citizens.

It´s important when you are about to build a new stable or just increasing your production that you choose the right housing system and that it fits your own farm. In this study I have put together facts about different housing system for fattening bulls in order to get a clearer picture of witch system is the most suitable for my own farm depending on the conditions I have. The background of this work is my own interest for breeding bulls and I will hopefully increase my own production. Due to this I wanted to learn more and increase my knowledge about different housing systems. Through a literature study I have found out the facts about the housing systems I find suitable for housing bulls.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Title: Social media as a communication tool - A case study on social media influencecorporate cultureLevel: Final assignment for Bachelor degree in Business and EconomicsAuthor: Jessika Klintsbacka & Oskar BergeSupervisor: Pär Vilhelmsson, Ernst Hollander & Maria Fregidou-MalamaDate: 2014-06-13Purpose of Study: The aim of this study is to inquire into Swedish companies internalcommunication, their approach to social media as an internal communications tool, and if itaffects the corporate culture.Method: The study is a multiple case study with a qualitative research design. The study'sinterview questions were designed by a operationalization of based on theory in the areas ofinternal communication, corporate culture and social media. The interviews took place inApril 2014. The interviews were recorded and then analyzed to bring out the similarities anddifferences between the companies.Results & Conclusion: The study shows that Swedish companies corporate cultures haveconnections with internal communication, and implementation of social media as acommunications tool. The study found that connections to companies with a comprehensiveone-way positive consider social media as alternative communication tool to strengthen theunity and community within the company.Suggestion for further research: One of the study's three companies is owner-led and thiscompany showed a high level of corporate culture.

This is a literature review of how the climate change affects the forest growth innorthern Sweden. The temperature will rise about 5 °C with the largest increase in thewinter season (December - February) and the CO2level in the atmosphere is expected tobe doubled. Precipitation patterns will change and increase with 25-35 % and theprecipitation will be in form of rain rather than snow. Today the forests in northernSweden are entirely dominated by coniferous stands. This may shift with the climatechange and results in a larger number of deciduous trees, preferably birch will becomestronger and grow better and faster.

The purpose of this essay was to increase the knowledge of and understanding about how teenage girls form their attiutdes towards sexuality and relations. The focus has been on discussing the research-question from four factors of influence chosen by the writers; sexual education, media, friends and family. Our intention with the study was also to take part of the teenagegirls´thoughts, attitudes and opinions in the matter, which is to keep the discussion on a structural level. The study is based on qualitativ interviews, in so called focusgroups, with all toghether eight girls in the ages 14-15 years, students in the ninth grade. The study has a postmodern feministic approach combined with a fenomenological and hermeneutic position.
