This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.

Viral marketing is a marketing tool that is becoming more common in the marketing industry. As people spend more time on the internet via their smartphones, tablets and computers marketers try to find new ways to reach out and connect with consumers. Succeeding with a viral spread is not easy; it's several factors that are important. Viral marketing encourages consumers to recommend and talk about product-related information with each other. So, what should a viral campaign or message contain in order to create this interest among us consumers? There are few empirical studies done in this subject which makes this kind of uncharted territory.

The purpose of this study is to explore active after-school teacher?s perceptions of the concept of meaningful leisure time. The purpose of the study is also to investigate if the interpretations of meaningful leisure time affect the perception of their work roles and after-school teacher?s actual work in a leisure activity. The study also provides an insight into how afterschool teachers perceive their roles in general.

The study aims to contribute knowledge about children's perceptions of the leisure-time as a learning environment. The study can be seen as an attempt to highlight the possible learning in the leisure-time, formally or informally.The study is based on two group interviews with a total of 11 children and was conducted by an interview guide with question areas to be discussed freely so that the children could give as full an answer as possible.Main results of the study show that children feel that they are staying at the leisure-time to get care when their parents are working and that they primarily associate the leisure-time with playing. The results show however that children feel that they learn things when participating in the leisure-time teaches controlled activities.It is possible to draw conclusions about the child actually experienced the leisure-time as a learning environment, but it can be difficult to identify when and how learning actually occurs. However, children do not perceive that there is learning while they play..

In school, pupils learn to critically relate to sources of various texts. In the course of time they also learn how to make references and cite properly. Yet, alarming reports show increasing cheating and plagiarism in colleges and universities. Plagiarism prevention services are used today in Swedish high schools. We are questioning how this relates to the sociocultural perspective and curriculum view of imitation as a natural part of the learning process, communication and language.Material from depth interviews, with four teachers in the school subject Swedish about their theoretical and practical approach to students' writing process and writing development are used to deal with the issues of this thesis.

The Swedish Public Relation industry has gone through a rapid growth in the recent decade. A peculiar, although perhaps not unexpected, development is that former politicians and politically employed individuals to a larger extent have been the subject of recruitment effort from the industry. Simultaneously there has been a public debate concerning the influence on Public Relations and Lobbying over the political agenda. The purpose of this thesis is to widen and deepen the discussion concerning Public Relations consultants. It centers on the individual consultants and takes their competence as the point of departure.

The aim of this study is to look at the way four teachers in, and five workbooks for, the course Svenska 1/A+B in upper-secondary schools include language varieties in their content. The research is based on qualitative and quantitative analyzes of the workbooks, where words and content are examined, and also interviews with the teachers who presents how they work with language varieties in their education. The results show that language varieties are accepted in school-education at the same time as they are, and have been, alienated in a way. The results also show that language varieties are less prioritized than other areas of education in the same subject..

Background: From a public health perspective it is of great interest to prevent the risk of noise induced hearing loss, because in addition to hearing loss, tinnitus and sound sensitivity also may lead to other health problems. About 1,4 million people in Sweden live with some form of hearing loss and 25000 of them are children under the age of 16. Studies have shown that hearing loss among adolescents is increasing and it is often associated with sound environments in their leisure time. Lectures in hearing prevention has been conducted in schools for adolescents but have not reached the desired results. Objective: To enquire caregivers? attitude, behaviour and perceived knowledge about sound exposure and its risks.

The aim of this thesis is to study the phenomenon of read/write OPAC by looking at how students at Pennsylvania University use PennTags in order to influence document descriptions in the library catalogue. The main questions to be answered are to what extent PennTags is being used in different subject areas and what users contribute to document descriptions through tagging in different subject areas. Studying the posts created by a sample of PennTags users from a quantitative approach I try to find out if there is reason to believe that the activity of users and users? possibility to make meaningful contributions are dependent of the subject matter being dealt with in documents described, as anticipated by the theory of pace layering. I find that user interest in influencing the library catalogue through PennTags appears to be low in general, with exception for in the subject areas of the main classes Language and literature and Social sciences in Library of Congress Classification.

Syftet med studien är att få djupare insikt i sångpedagogers syn på Time och Sväng samt hur de didaktiskt arbetar med dessa aspekter. Det saknas mer omfattande forskning inom området. Med detta i behåll har jag för avsikt att få djupare insikt i frågeställningar som rör olika förhållningssätt till hur sångare kan öva upp Time och Sväng samt vad Time och Sväng innebär, generellt och i ett undervisningsperspektiv. Studien har som sin teoretiska utgångspunkt ett sociokulturellt perspektiv med fokus på hur människor använder olika redskap för att kommunicera med sin omgivning.För att få svar på mina frågor har använt mig av en halvstrukturerad intervjuform när jag samtalat med informanterna. Alla informanter i denna studie arbetar idag som sångpedagoger; två av dessa är mer inriktade på jazz medan de andra två är mer inriktade på populärmusik.

Vaginism är ett sexuellt problem som förekommer hos kvinnor och som i tidigare utvärderade behandlingar betraktats som kvinnans problem. Forskning inom området vaginism är begränsad och kunskap om parrelationens roll för vidmakthållandet av problematiken och upplevd relationstillfredsställelse saknas. Studiens syfte var att utforma en parbehandling där kommunikationsinterventionen validering lärs ut som färdighet, utforska om det fanns ett intresse för deltagande, samt utvärdera om behandlingen kan påverka relationskvalitet och individuellt välbefinnande. Studien använde en single subject design där ett par fullföljde behandlingen. Resultatet visar ett begränsat intresse för deltagande och ingen större effekt av interventionen.

I have always been interested in sports, so when it was time to write the paper I chose to write about sports and economic.It has led to this problem: How is the function of management control and planning problems in sports?   Sports clubs are non-profit association and non-profit organizations aim to support members? moral and economic interests.

This study has examined how teachers in Swedish upper secondary schools work to foster a critical perspective through the education in the subject of Swedish. The study is based on qualitative interviews conducted with three teachers, who have given their views on the role of source criticism and critical analysis of literature in the subject of Swedish. Furthermore, they have described how they incorporate these views into their own teaching.The study has shown that the teachers find that source criticism and literary analysis are interconnected, since both depend on a general critical approach, which they both help foster. The main question the study examined was how Swedish education could help foster a critical perspective. The interviewed teachers' ways of working point out a way: teacher C has integrated source criticism and referencing into most of their education, which makes them central to the education in Swedish.

The aim of this study was to search for a link between the subject pictorial studies in means of expression and the ability to communicate in written and spoken language. To do so findings in relevant literature and a few complementing theories was addressed to cast light on interviews made with teachers dedicated to the subject pictorial studies in a subject-integrated curriculum.Interviews were conducted with nine teachers and all but one were teachers in the subject pictorial studies, spread across all of the nine grades in compulsory school. Informants were located in areas of socioeconomically high as well as low status, in central and densely populated areas as well as areas less densely populated. The diverse theoretical background consisted of semiotics, constructivist theory, social constructivist theory and genre theory. Theories and literature partly both contradicted and supported each other, depending on situation and circumstance.No evident conclusion could be made that discriminated one affecting cause from another on speech or writing skills.

The aim of this study is to bring forward four teachers of Arts-education, their statements and reasoning concerning the condition and meaning of the subject of Arts-education along with their statements in relation to theory and earlier research, give voice and insight in their intentions according to what teaching of Arts-education should contribute to.The basis for the study is brought out of the dilemma that there, in the subject of Artseducation is ?crowding of matter? in the nine-year compulsory school, difficulties in selecting the importance of various subjects and different opinions between teachers, due to curriculum being modified in accordance with the development in society. The earlier research that this study relates to shows how teacher?s opinion of different subjects varies. My questions concerning the subject are the following;How do four teachers of Arts-education reason concerning the condition and meaning of the subject of Arts-education?What are the teachers intentions according to what teaching of Arts-education should contribute to?What are the similarities and differences between the statements of the teachers in this study versus the teachers' statements according to previous research?To find answers on my issues and questions I have made interviews with four teachers of Arts-education and have then put their reasoning and statements against theories , which  all concerns the creative process.
