Question:"Does the market possess perfect information as the efficient market hypothesis says?""Is there any significant relationship between the abnormal stock return on the ex ? day and the dividend?" Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex ? day and try to figure out if abnormal returns occur on the portfolio during dividends.Methodology:The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 ? 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days.

Today many companies are global and can exist all over the world. It is more common that projects are conducted in different locations, from various cities in a country to nations in different parts of the world. To manage projects both traditional practices such as the Waterfall method and new flexible methods known as agile methods are used. How is the process affected when a project is distributed, when the team is scattered in different places? This makes it difficult to create a good project, something we will discuss and try to find solutions for.

Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.

In today?s society there is an ongoing debate concerning gender distribution amongst the top executives and there is a clear distinction between the men and women in leading positions. The reason for this can be because men and women to a certain degree conduct leadership differently. It is said that men are more focused on task oriented leadership while women seem to focus on a relation oriented and more interactive leadership. A leader?s success could be due to his or her ability to set up and use a network.

Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.

Vocal technique and interpretation are the key elements of voice training. Thepurpose of this article is to investigate what vocal technique and interpretation meanto teachers and students and how they would describe the relationship between thetwo. The questions at issue, intended to be answered in this article, are the following:What is the relationship between vocal technique and interpretation? How should theteaching be structured for the students to experience progress on the musical plane?What role does the teacher have in the musical development of the student?This is a qualitative survey and the methods of investigation are semi-structuredinterviews and classroom observations. Presented in the article are a number ofresearchers and writers whose thoughts on the subjects have gained great importanceto vocal teachers and students, as well as leading the research on the voice and itsfunctions forward to higher grounds.

Over the past twenty years, the cooperation within the European Union (EU) has strengthened and expanded with both more number of Member States and stronger influence on international politics. The unique character of the Union and its ability to enforce peace and humanitarian intervention has attracted attention in political science. This prominent position of the Union is perceived by many scholars who often hold this derived from the Union's influence in international relations. Various terms have been used to define the powers of the Union. The British researcher Ian Manners states that the unique identity of the Union in the international arena is formed by its normative power.  An important policy area within the Union is the environmental cooperation.

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

Internet's entry into our home has changed our communication capabilities. As a result more and more services in the digital world are available. Besides e.g. shopping, gaming and general information, different social networks now offer preventive and therapeutic health-oriented services. When being asked by several young people, with whom I have been working in a clinical setting, to offer conversations over the Internet that enables both to see and to hear each other in real time, I decided to conduct a pilot study which is presented in this paper. The aim was to investigate the feasibility of offering supportive therapy using video calls over the Internet.

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

The purpose of this study has been to examine reading habits and the use of the library by pre­school teachers in a mainly multicultural community, and also explore to what extent activities in the local library are aimed at preschoolers.The study used a sociocultural approach based on Vygotsky?s theories of learning and development and Söderbergh?s theory of early childhood language development, and was carried out during the summer 2009. The methodology used was both quantitative and qualitative, with a combination of questionnaires and interviews. Questionnaires were sent out to each section of the municipal pre­schools within the catchments area of the local public library in a multicultural suburb of Uppsala. Three short interviews were carried out with staff at the local and main library branches, as well as library staff at the County Council.The results show that, although preschool teachers find reading important in their work, many teachers read spontaneously and/or sporadically.

The Master Thesis has been carried out in cooperation with Silva Sweden AB and the objective was to develop a new product concept within the product category for everyday exercise. The purpose of the thesis was to use and analyze methods and tools which aid creativity and concept creation in order to make method recommendations for future projects.During the thesis a number of customer needs were identified, which in turn were translated into 20 concepts. On a concept decision meeting a pedometer-based concept was chosen for development. The new pedometer is in addition to counting steps also able to measure and calculate the user?s total climbed height during a day and present this graphically in comparison to famous monuments or distances.

The new accounting standards IFRS and IAS was implemented in January 2005, the purpose was to harmonize accounting standards world wide. As a result of these new rules the real estate companies are allowed to appraise real estates assets at market value. It has long been debated whether this appraisal fulfils the requirements for relevance, reliability and comparability.The paper attends to how banks control the information given by the real estate companies in the process of credit granting. As an introduction we describe the purpose of accounting and the problematic´s about appraisals with market values. Further on there is a discussion on which factors are taken into consideration when banks grant credits.The study is built on interviews at three different commercial banks.
