Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.

Annual reports are by many considered to be companies primary way to inform their world where the CEO's words are read most carefully by shareholders. The purpose of this paper is to examine the design of the CEO's words in annual reports in light of the financial crisis in 2008. The study seeking explanations for change, similarities and differences in the various texts based on three themes which are results, future and confidence. In this qualitative study five CEO's words are explored by means of a discourse analysis, all from large Swedish industrial companies listed on the Stockholm Stock Exchange. Some of the results shown is that the CEO tends to talk about the company's results in a self-serving manner and CEO speaks more aboutm the results before than after the crisis.

It has become more and more common that companies in the service sector are beginning to understand their own effect on the environment and thus the need to contribute to a sustainable development through acting in a deliberate way. Serious environmental work can help a company to improve their image and in that way win competitive advantage that leads to improved profitability. In a short time perspective, adjustment to the environment is an opportunity to gain competitive advantage and an opportunity to develop a profile. In a long time perspective it is about survival. The environmental work has become a sequel to the work with quality.

This study includes a life cycle assessment, LCA, on an ecological produced cotton shirt for the company Reflective Circle, which designs ethical and ecological clothes.Initially were cotton farming and textile production studied to gather basic knowledge about the processes. Since this shirt is being ecological produced in the whole production chain, we studied what an ecological production means, but also how a conventional production works. When this was done we could start to discuss the differences and similarities between the production of the shirt and general conventional production.When the LCA was first initiated, the main focus was on the green house gas emissions from the manure at the cultivation. Thereafter the process steps such as picking, ginning, carding, spinning, weaving and sewing were being studied. The picking is done by hand, but the rest of the processes are handed by machines which consumes energy.

In Sweden there is a large interest in renewable energy but the market for solar power is still small compared to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish farmer to produce electricity and there is an interest among the farmers. The agricultural branches in Sweden most suitable for solar power are pig production and poultry due to the even electricity need throughout a year. Swedish pig farmers are going through a period of unsteady profitability which makes it interesting to see whether producing their own electricity can affect the economic situation.

This study has investigated what makes a business relation satisfactory. The purpose is to distinguish the factors that are relevant to a functioning cooperation relationship between sawmills and DIY-stores.

This paper presents empirical evidence on the determinants of interest rate swap spreads in Sweden during the period 1999-2003. The results suggest that the spread between STIBOR and the general collateral repo rate is positively related to shorter maturity swap spreads. The risk premium associated with commercial bonds is positively related to swap spreads of all maturities. A negative relationship is observed between the term structure of interest rates and swap spreads. The short-term interest rate is positively related to spreads with shorter maturities.

Studien undersöker spelares sociala upplevelse inom online dataspelet World of Warcraft (Blizard entertainment 2004). Detta görs genom att studera de designförändringar som sker med verktyget "Guild" från 2004 fram tills Juni 2013.Verktyget "Guild" är avsett för att ge spelare ett sätt  att skapa grupper, så kallade "guilder" som kan närmast efterlikna föreningar inom verkliga livet. Studien har haft som syfte att försöka förstå den sociala interaktionen som kan äga rum i olika "Guilder". Det är sedan planerat att använda sig av Simmels teori om interaktion och artikeln "The Metropolis and Mental Life? (1903) för att förstå spelarens upplevelse.
