The study proceeds from a phenomenom called co-creation. If value can be created, it is logic to asume that it also can be destroyed. This phenomenom has earlier not been applied to long-term relationships such as business to business. In a business relationship it is important to identify factors, that leads to co-destruction, to be able to prevent them from appering. The purpose of this study is to identify which factors leads towards co-destruction.The study have used theories from Echeverri & Skålén (2011) which has designed a model explaning the outcome of co-creation and co-destruction.

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

Background: Most acts of violence in a psychiatric ward are directed towards the nursing staff. Aggressive behaviour often stems from feelings of frustration and powerlessness in patients while committed and therefore having limited liberties. To avoid an escalation of a hostile situation, it is important that the nursing staff applies the kind of encounter that will yield a positive outcome. Aim: The aim of this literary study is to elucidate the possible encounter the nursing staff can apply when encountering a hostile patient in psychiatric care. Method: The literary study is based on twelve scientific articles.

Electrooculogram (EOG) data was used to develop, adjust and validate a method for drowsiness detection in drivers. The drowsiness detection was based on changes in blink behaviour and classification was made on a four graded scale. The purpose was to detect early signs of drowsiness in order to warn a driver. MATLAB was used for implementation. For adjustment and validatation, two different reference measures were used; driver reported ratings of drowsiness and an electroencephalogram (EEG) based scoring scale.

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

This work is meant to contribute to the research of adaptation studies by focusing on a special case: the transformation of a fictional diary into a movie. In order to sustain the form of the literary source the adaptation to movie requires certain strategies. Först of all, the diary genre is characterized by a one-dimensional narration. Second, diaries only supply a few written dialogues, hence this "void" has to be compensated and filled by media specific measures. Third, the investigated diary is a story of individualization and emancipation of a single woman.

The purpose of this thesis was to explore how Swedish librarians working with educational matters In Swedish: studiebibliotekarier experience his/her pedagogic work in the context of a public library. My intention was thus to reach an understanding of how they experienced their educational work. The following questions were asked: 1 How do the librarians experience the physical environment created for their students? 2 How do the librarians experience the co-operation with others involved in their work? 3 How do the librarians experience the formal task that he/she now is given? 4 How do the librarians experience their own pedagogic qualifications regarding the demands that are made upon them by the students? I have interviewed six librarians and incorporated theories on pedagogic roles in an educational context. I reached the conclusion that these librarians believed the environment to be important for the outcome of the students success with their studies.

The aim of this study is to look at the environmental effect on toddlers? social interactions during free play in two older and two newer preschools. Furthermore, we would like to investigate four preschool teachers? thoughts about the indoor environment when it comes to toddlers? interaction during free play.Qualitative methods containing interviews of the preschool teachers and observations of the children during their free playtime have been used to help us reach our conclusions. In addition, our theoretical conclusions have been derived from both the sociocultural perspective and the environmental psychology perspective.Our results have shown that variations in the preschool environment are of importance in the outcome of toddlers? different social interactions.

The aim of the study was to illustrate how music therapy can be used in the care of patients with schizophrenia and other psychotic illness.The method used was a literature review. Scientific articles were searched in PubMed, Cinahl, PsycINFO och Scopus databases with an outcome of ten articles, with in total 330 participants, that underwent quality and outcomes analysis.The results showed that music therapy could provide potential improvement in the patients' social functions and that it could also improve negative, some positive and general schizophrenia and psychotic symptoms in some patients. The form of music therapy used was often creative music activities with music therapist, with or without structure, or individually customized. The length of treatment varied widely. It was not possible to draw conclusions about which type of music therapy was best.

The aim of this essay is to study five teachers' perceptions and experiences of a multicultural class. I want to find out how they relate to intercultural education and how they experience that they may apply it.Sweden is a multicultural society. This fact is even reflected in the school and this imposes on teachers finding new ways to educate and prepare their students for the multicultural society.I chose to carry out a qualitative survey and interviewed five teachers having contact with a multicultural class. The study also offers suggestions to future teachers who can benefit from it in terms of adopting convenient attitudes in multicultural classes with better understanding.The outcome reached shows that the interviewed teachers try to make use of intercultural pedagogy by addressing differences between students, adapting teaching to supply for the needs of students, and also by having good contact with parents. But teachers also experience difficulties.

Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

In this comparative study, intelligibility (as measured by SWINT; SwedishIntelligibility Assessment) and self-rated communicative ability (as measuredby SOK; a self-report questionnaire concerning communication) were investigatedin 29 young adults with repaired cleft lip and palate (CLP) and in 50 age-matchedcontrols. The purpose of the study was to investigate if the outcome of these measuresdiffered between groups and/or with regard to sex, and also to identify possiblecorrelations between SOK and SWINT. Results show that young adults withrepaired CLP had a more positive attitude towards their communicative ability thancontrols, as did men with repaired CLP compared to male controls. Intelligibilitydid not differ between the two groups. A correlation between degree of intelligibilityand self-rated communicative ability was found in young adults with repairedCLP.

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.
