The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

Human-animal interaction is suggested to be a main feature within livestock production. The quality of handling, for instance, appears to be greatly depending on the attitudes and behaviour of the stock people. Various studies have been conducted on relationships between human and animals, but few have looked upon differences in human-animal interaction and attitudes between countries. Two countries often discussed in livestock production are The Netherlands and Sweden. It would be of interest to compare these two countries to find out whether (assumed) differences are reflected in the attitudes between animal handlers.

The purpose of this study is to examine escort-business with a focus on sales of BDSM-services (Bondage and Discipline, Dominance and Submission, Sadism and Masochism). The study is based on qualitative interviews with three informants providing BDSM-services, as well as a survey with 96 men who requested domination of escorts (the survey was carried out by an escort in the 1980s). The analysis of this material resulted in the identification of three themes on which the study centers: The personal experiences of the three escorts, the interaction between the escorts and the clients, and the changes over time when it comes to the performance of BDSM-services. The study has a gender perspective. The important conclusions are that there are several differences between prostitution having a focus on BDSM-services and other prostitution.

Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.

Social media has become an important marketing and communication tool worldwide, mostly through the largest social platforms Facebook and Twitter. With two-way communication via Internet companies has gotten the opportunity to interact and communicate directly with their customers. Facebook has been the focus point through the study because it has shown to be the most efficient and frequently used platform for communication. Our study aimed to confirm how communication via social media actually looks like. To be able to reach the best results, we have conducted the study from a phenomenological approach, which means; usage of qualitative semi-structured interviews to reflect the respondents experience on the phenomenon social media as a communication tool. Social media has shown to be a great way of communicating externally for companies who are willing to spend time engaging in the platform.

During a major part of modernity the concept of identity was something that in many ways was predetermined for the individual. People in general remained in the same social spheres as the generations before, shared common religions and beliefs and where more or less bound to a geographic area. Identity and lifestyle was something that was adapted quite unreflected from habit and tradition. Though, during the cultural modernisation process that took place in the twentieth century, previous shared patterns of interpretation vanished and became individual.  Finding references, constructing an identity and establishing a self became individual.

The aim of this study was to examine how individuals who have left a criminal lifestyle may experience their present life. A symbolic interaction approach was the theoretical framework for this research. Qualitative interviews were conducted with seven individuals who have stated having had and left a criminal lifestyle. The results showed that how individuals experience their present life is highly dependent on individuals? own view of themselves as well as on how others view them.

This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.

The overall purpose of this essay was to provide a better understanding of the importance of discretion for social workers in direct social services. To answer the purpose three questions were formulated: (1) How do social workers define and describe their discretion and their ability to independently accomplish their work? (2) How do social workers experience that workplace organization, policies and economic conditions interact with their discretion and (3) How do social workers experience that the interaction with the client can affect how they use their discretion in the individual case? The method used was qualitative interviews. The theoretical framework was Michael Lipskys (1980) Street-level bureaucracy and the four themes organization, professional role, skills and interaction.The results showed that the respondents, although they did not consider themselves to be affected by the economy still adapted to budget restrictions when they said that they were cost conscious in their work. This adjustment to budget framework could possibly be what made them not feel limited in their work.

In this paper my aim is to understand the trance movement from within as a collective phenomenon. I went to Turkey with my boyfriend David on a trance gathering, a festival called A Total Solar Eclipse Festival. There I did participant observations and interviews.Can Collins theory about interaction ritual be useful to raise the understanding? And is it fruitful to apply the term collective identity?The collective identity is build up by the festival as interaction ritual. It generates solidarity, emotional energy and a sense of belonging.In this paper I discuss different categories and symbols that the collective identity contains of.

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

This thesis examines the interaction between European football and the European Union and if it can generate Europeanization. By using theories of Johan P Olsen and Claudo M Radaelli a theoretical framework was constructed in which Europeanization is seen as an interaction between the European level and the domestic level. The Europeanization is regarded as a two way process with elements of top-down and bottom-up pressures. The study focus on the changes and the actors in the Europeanization process and how the European Union as a top-level and European football as a bottom-level influence each other to European changes. The theoretical framework is used to analyze the Bosman case and the Cotonou agreement's implementation in a Swedish football context.
