Green IS ? a Systematic Literature Review
This thesis provides a systematic literature review of a selection among current papers andarticles on Green Information Systems (IS). The main focus is on the current state of Green ISin academic research. This study aims at gaining a deeper understanding and a clearer view ofthe state-of-the-art of IS for environmental sustainability research, with the goal of clarifyingthe diffuse idea of what Green IT/IS is, and what differentiates Green IS from Green IT.To support the objective of this study, the articles selected for data analysis were collected byusing a systematic literature review as research and analytical method. Within the thesis, adescriptive angle with an interpretative character is used to analyse the data extracted.A theoretical framework based on concepts from sustainability, Green IS and Green IT isemployed in order to analyse and compare terminologies and frameworks used in the studiedarticles. Furthermore, the different dimensions of sustainability and the various terms used todescribe Green IS are analysed comparatively.The result and analysis are discussed in a conclusion confirming the on-going ambiguity ofthe terms Green IT and Green IS and the transformative power of IS.
Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige
Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.
Utvärdering av energiberäkningsprogram : Att användas i tidigt planeringsstadium för byggnader
The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.
Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn
The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.
Hur tron finner ankarfäste. Pastorers informationssökande i sin andliga tjänst
This Master?s thesis concerns the information behaviour of pastors in nonconformist churches (especially new evangelical and Baptist church communions) in Sweden in their spiritual service to the local parish. The thesis also looks into how the information flow functions in the pastors? context and why the information need appears as it does. The theory used in this study is contextual analysis based on Buckland?s, Weber?s and Patrick Wilson?s theories on authority and power structures.
Skriftspråksskillnader? : En jämförande studie av flickor och pojkars skriftspråk på gymnasienivå
Our society has faced monumental changes and therefore our working life has changed as well. We are now in the twentieth first century and still our labor market is gender-segregated. Today networking is an important part of working life and one cannot emphasize enough the importance of having good connections in your network. Networking is now seen as an important tool when it comes to your career. In the past networking has been the men?s arena and it has almost been seen as a male institution.
Peltierelement - spillvärme till el : Peltier element - waste heat into electricity
The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.
Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.
AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket
The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production.
Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy.
The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.
Konstruera och rekonstruera traditionell kunskap - en diskursanalytisk studie av texter om internationellt utvecklingsarbete
The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.
Idealister eller idioter? : En studie av mediers framställning av Johan Persson och Martin Schibbye under och efter fängslandet i Etiopien
The idea to this bachelor thesis was born after carefully following the coverage of Johan Persson and Martin Schibbye in Swedish media during their imprisonment in Ethiopia from June 2011 to September 2012. Based on our interest we designed two questions to answer throughout the thesis. These are:(1) How are Johan Persson and Martin Schibbye portrayed as journalists in the discussion about them that has taken place in Swedish media?(2) How is the journalistic profession described in the discussion about Johan Persson and Martin Schibbye in Swedish media? To answer these questions we decided to analyse texts that can be defined as the genre of opinion journalism, which all came from Swedish printed media. We have chosen 16 texts to analyse which show the variety of ways to write about Persson and Schibbye in the chosen genre during the chosen period of time. Opinion journalism is what newspapers use to attract readers, as they want to supplement the news coverage with comments and analysis from ?experts?. Persson and Schibbye were imprisoned in Ethiopia in June of 2011, and weren?t released until 15 months later, in September of 2012. To analyse our material we have amongst others used theories regarding social constructionism, representation, discourse, the journalistic identity and the journalistic ideals that exist in Swedish society.
Valresultat och börskurser : En eventstudie om riksdagsvalens effekter på Stockholmsbörsen
Background:It is always fascinating to observe the events that affect the stock market, especially as the numbers of influencing factors are so many and various. Political elections are important events in society and affect the corporate environment in different ways depending on which political party that is in power. This brings up the question of whether political elections are important enough to affect the stock market; and it is this question we intend to analyse in this paper.Purpose:The purpose of this paper is to investigate whether political elections affect the stock market and to discuss the reasons for any possible affect that might be found.Procedure:An appropriate and thoroughly tested method to investigate if an event affects the stock market or not, is to do an event study. Subsequently we chose to do an event study on whether the Swedish general elections in 2002 and 2006 affected the Stockholm Stock Exchange. In order to give the analysis more depth we have also chosen to interview people with knowledge of the stock market.
