This project was aimed to study the degradation of polystyrene-butadiene-styrene block copolymer (SBS). SBS is used to modify bitumen, the binder in asphalt. From earlier studies it is known that SBS degrades in bitumen, but the degradation products have not been identified. To be able to determine the long term effects of SBS in the environment, degradation products need to be identified. Polystyrene forms rigid blocks with polybutadiene as a rubbery matrix between the ridgid blocks.

On the first of January 2012, a new public authority was formed in Värmland, due to a new legislation on public transport. The first task for the new public authority was to produce a plan for the development of public transport. In order to do so, it had to execute an extensive consultation process about the long-term goals of public transport. The purpose of the thesis is to investigate how a public authority can use a consultation process as a means to clarify accountability and produce unified goals. To answer that, I have done a case study about how the new regional public authority in Värmland for public transport has acted in the process of writing a plan for the development of public transport.

The purpose of this thesis is to examine Skogsstyrelsens event Skogens Dag as an information channel by looking at information use and information behaviour during the communication process of the event. This is done by examining the aims of Skogsstyrelsens information distribution during the event in relation to its outcomes. The evaluation is focused on long term effects on the target group and it is restricted to Skogens Dag in Borås 2005. The question this thesis intends to answer is: How does the event Skogens Dag function as a tool for information distribution? The theoretical background gives an account of the communication process as well as the relevant aspects of marketing, social marketing, campaigns and public relations, as these are communication attempts that can use an event as a medium.

The purpose of this essay was to in a specific project for unemployed youths between 18 and 24 years, from an ecological point of view, examine how the youths experienced their unemployment and also to compare the purpose and structure of the project with the participants' experience.Important questions in my essay were how the unemployment affected the youths' identity and social circumstances, if the participants found the project meaningful, and experienced that they could influence how the project was formed, if the purpose of the project was in accordance with the youths' experience and how the ecological perspective could be used to understand the situation of the youths.To answer these questions one interview was made with one of the employees and five interviews were made with participant youths.The results of the essay was that the youths' experience of the project were very much individual. All of the participants found something in the project meaningful and most of them thought that it was possible to influence the project in some way. Something that both the youths and the employee pointed out as important was the employees and their supporting role..

The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.

In this thesis the pragmatic pedagogy as formulatad by John Dewey is applied to theswedish national campaign Digidel and its work to spread the digital participation among thegeneral public. The purpose of the thesis is to visualize and problematize that differentunderstandings of a problem, lead to different solutions, as lifted in John Dewey´s pedagogy, thatconstitutes the thesis' theoretical framework. The term digital participation is used by the Digidelcampaign, where public libraries take active part to spread digital participation througheducational efforts. By qualitative interviews with four librarians this thesis examines howunderstandings of the term may vary and in turn lead to differenent educational goals, designsand executions. The result shows that basic computer- and Internetskills are seen as either equelto or prerequisites for digital participation and that the digital participant is seen as either apassive recipient or an active participant.

This essay attempts to examine whether it is possible to find a mutual understanding of the concept of drive between Spinoza?s philosophy and Freud?s psychoanalytical theory. Former texts on this subject have given a variety of conclusions: from a radical separation between the two authors to a complete identification between the two. The drive, or the desire which is the term Spinoza uses, has in Spinoza?s philosophy its foundation in the concept of conatus.

This essay is about the planning of Stockholm's border regions (areas on the outskirts of the city) during the first seven years of the 21st century. It describes how planning decisions are made in reality, in respect to a 'green' perspective. By describing what a "markanvisning" is (the right to negotiate with the city about a certain piece of land) and by discussing examples of what has happened with a hundred applications for markanvisning, this essay shows how Stockholm's border regions are planned. In the majority of cases it is the initiative of the future developers that begin the planning and construction processes. Research shows that the application to get a markanvisning in Stockholm does not follow a clear, structured system. However, the existing system in Stockholm does work and it seems like almost all the employees within the municipality, the politicians, and the future proprietors are happy with the current situation. Interviews have been held with key individuals involved in the planning process.

The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.

AbstractThe purpose of this paper is to analyze TPL companies, and their collaboration with their customers from a TPL perspective. The paper intends to get a bigger understanding of their collaboration, advantages/disadvantages and how the collaboration can be improved. The foundation for the paper is obtained through questions that have been created from the chosen theories about supply chain, third part logistic (TPL) and lean production. We have had open interviews with five different conveyers where we have had our questions prepared and during the interviews asked new questions to get more distinct answers. When we subsequently analyzed the empirical material and by chosen theories we have been able to confirm that the collaboration between the TPL companies and their customers is more of a partnership character.
