Att mäta fattigdomsbekämpning - En studie av social performance-rapportering inom mikrofinans
This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.
Utvärdering av effektstyrningssystemet EnergiDirigent® ur ett miljöperspektiv
Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.
Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme

Case Pöyry Sweden AB : Miljöprestandaindikatorer för ett tjänsteföretag
The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.
Utredning av fastighetsel i ett äldre och ett ombyggt flerbostadshus i Gävle
The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..
Miljö eller avkastning? : en investeringsjämförelse mellan gammal och ny energi
The purpose with this study is to investigate funds that are environmentally friendly. Environment issues has become a large subject that affects all aspects in today?s society. It is a global issue which has affected the awareness of environmentally friendly products and its benefits for the environment.How has this awareness affected the financial market? In this study the authors have looked at six environmentally sound funds and six energy funds to answer the question if it´s better to have your money in traditional energy or in renewable energy.This study is made in an quantitative way, the data has been gathered from the internet database Morningstar. The energy funds have had its biggest assets in companies dealing with oil, and the environmentally sound funds have had its biggest assets in renewable energy. Bye looking at the different funds rate of return and relating that to risk managing theories of Sharpe and Treynor, the authors compared the two types of funds.During the period that was looked at during this study ( third quarter of 2007 until third quarter 2010) the energy funds outperformed the environmentally sound funds in every aspect. .

Operation Moked : Sexdagarskriget ? Överraskning inom de israeliska luftoperationerna
The research regarding the six day war and the aerial operations named Operation Moked is extensive but there are certain shortcomings in the research that examines both the operation and the principle of surprise.The aim of this paper is to contribute to this research by utilising existing military theories on the principle of surprise in order to identify indicators that are representative of surprise. These indicators are thereafter used in a study of Operation Moked in order to examine the extent of in which the principle was utilised.The result of this research goes to show that the principle of surprise was utilised in great extent by Israel during Operation Moked..
Republicans in the White House - Hard times for Soft Power? En teoriprövande studie om skillnaderna i soft power mellan demokratiska och republikanska administrationer
According to many scholars America's soft power is in decline, a power resource whose importance has been increasing in world politics. This makes it interesting to examine if there is a difference between how Democratic and Republican administrations wield their soft power.This thesis is a hypothesis-testing study and the purpose is to test the hypothesis that Democratic administrations, to a greater extent than Republican, can create, utilize and defend soft power. My thesis is based on Joseph Nye's theory of soft power and the focus of this study is the aspects of the foreign policy resources. In order to measure this concept I have made my own operationalization where five different indicators serve as my guidance. I use the method of least likely-cases to select and motivate the administrations being tested, which gives me a comparative study of the Democratic administrations of Lyndon Johnson and Bill Clinton and the Republican administration of George H.
Enegiutredning Hotell Princess
This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.
