About 35 years ago the WHO advocated that countries with injecting drug users should introduce the so-called needle exchange programs (NEP) to curb the spread of infection by blood-borne diseases. In Sweden the first NEP started 1985 in Lund, but the program was extremely controversial in a country with such a restrictive drug policy like Sweden.The study you are about to read shall process this controversy, when a NEP opened in Stockholm, by analyzing the articles published in the newspapers Dagens Nyheter and Svenska Dagbladet. By using discourse analysis as a processing tool we?ll try to see the difference between the two chosen newspapers. We will identify and analyze the different participant?s, such as doctors, politicians, user associations and media, arguments in the needle exchange issue.

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

This thesis aimed to study the interaction between an educational technology system and its users and give suggestions for design improvements. The technology system is called EDIT (Educational Development through Information Technology) and has been developed and applied at Linköping University?s Faculty of Health Science. EDIT supports Problem Based Learning and enables scenarios to be presented through the World Wide Web. The study was divided into two parts.

Most major companies today have a visual identity. It answers questions like: which font do I use? and when can I use the logo or not? Westinghouse Nuclear Fuel in Västerås have a visual identity but no guidelines for the employees to follow. Further-more, rollups and rollup handouts produced by Westinghouse are not mentioned in the visual identity. ?erefore the external information from Westinghouse is someti-mes, both by employees and customers, perceived as not uniform.

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.

The public library is an institution that throughout history has been associated with anumber of social codes, that seem to be deeply rooted in the minds of the public. Thesecodes regulates how users act and interact in the library environment and as a library useryou have to obtain knowledge about these social codes.This master's thesis aims at studying how these codes are transferred to children in the earlyschool-age, how children react to the social codes and what effects they have on thechildren's development into library users.The empirical material used in this study consists of observations and interviews. Theobservations are conducted during two school classes visits to a public library and focuseson the interaction between librarians, the children and their teachers, and the interviewswere conducted with the two librarians responsible for the library visits.The theories used in this master's thesis consists of symbolic interactionism, in the form oftheories by George Herbert Mead and Erving Goffman, Peter L. Berger and ThomasLuckmanns theories regarding the concept of institutions. Another theory that's used in thismaster's thesis is the one concerning the social aspects of information literacy focusing onthe concept of epistemic communities as presented by Kimmo Tuominen, Reijo Savolainenand Sanna Talja.The result of this study is that the social codes are communicated to the children primarilyby the teachers rather than the librarians.

In this Master's thesis we investigate the collection management regarding fiction for adults. The apprehension of fiction has changed over the years. From the beginning it was considered to be mostly educational rather than being the purpose of entertainment. As for today these views are not opposites to each other. Regarding this we discuss the problem concerning terms of quality.

In this thesis we have developed a framework of features associated with eCommerce platforms and then defined them. Thanks to our interviews with eCommerce-developers, we have been able to define multiple eCommerce features with the focus on an owner?s perspective. Much of the previous research in the area, takes a user perspective when the functionality of eCommerce-platforms have been assessed and evaluated. We have therefore taken an owner?s perspective in the evaluation of eCommerce platforms and therefore produced a suggested framework with key features associated with the owner's functions.

Today it is not unusual to use a secondary screen to accompany a primary screen. The possibility to integrate these two in the form of an application for the secondary screen have long been possible but have not been developed to full potential. This thesis aims to study the use of the extra information and functions this type of application would make possible and how this type of application could be used.For this study a prototype-application including a real time newsfeed and a static menu for a specific episode of a Tv-series was created based on the information collected in an online survey. The application was tested on a number of people who got to evaluate the experience in short interviews and were given the possibility to recommend changes in the application.The result after the study showed the people where torn about what kind of information would best fit the application but showed over all that a dynamic newsfeed with information continuously updated with the episode where most appreciated. The problem with the difference in interest around the categories would be solved first and foremost by the application being configurable so that every single user has the possibility to choose which kind of information to be updated in the newsfeed.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

The purpose of our study was to identify and present experiences encountered by parents with a child with diagnosis. Those narratives are made open for the public. Data has been collected through ten interviews with parents having children with a diagnosis. These interviews have also been complemented by interviews with one child and one youth. The parents and the children who have been interviewed, all have their own stories and experiences of how it is to live with a diagnosis in the family and for all families there are different diagnosis.

When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

This paper aims to examine the mother tongue subject and it´s existence and condition in a school located in the south of Stockholm. I have performed interviews with four teachers about their opinions and attitudes regarding the mother tongue subject in the school were they work. Two of the teachers are teachers in social studies and two of them are teachers in the mother tongue subject. My aim is also to examine whether an interest exists among the teachers to collaborate in between the subjects and what possibilities and conditions such collaboration would have in effect. I have applied a qualitative method based on personal interviews with semi-structured questions as my data acquisition method.

The aim of this master´s thesis is to examine how librarian´s views of the users can vary for different types of materials in public libraries. We have seen that literature and reading are the central parts of the libraries in Sweden. All other types of media are traditionally seen as complements and in focus for the study is feature film as an example of these other medias. We examine policy documents to see the official view of the general target group of the libraries and compare it to the view of the users of feature films as expressed by the librarians. The study includes several different types of empirical materials such as interviews, observations and documents and the method used is case studies.
