This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

The aim of this study is to investigate a number of class teachers' thoughts on the use of information and communications technology (ICT) in early literacy learning. The study has been conducted as a qualitative study, interviewing five teachers with the help of an interview guide. Three central questions were posed.What perception do the teachers have about the use of ICT in their tuition?What perception do the teachers have about the pupils' literacy learning in teaching with ICT tools?What perception do the teachets have about teaching and learning by means of ICT when it comes to pupils with reading and writing difficulties/dyslexia?The overall theoretical basis of the study is Vygotskij's sociocultural theory.In conclusion, the result of the study is as follows.Most class teachers feel that the training they have undergone in ICT education was adequate, but they also call for skill development.Most teachers believe that the use of ICT tools provide opportunities to adapt their teaching to pupils' knowledge level. The teachers' opinion is that ICT in teaching is useful for pupils' progress in early literacy learning.Most teachers also believe that ICT tools in teaching can be of some help for pupils with reading and writing difficulties/dyslexia.One obstacle in helping these pupils is lack of time.Therefore, the majority of the teachers hand these pupils over to special education outside the classroom..

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

The purpose of this paper was to study the various organisations that work with drug abusing homeless people in Lund. We have tried to compare the possibilities they have to change the way the homeless people look at themselves. The organisations that we have studied are Aluma, Diakonicentralen, the shelter Piletorp and the social welfare office.The methods used to collect data were interviews with professionals and homeless people as well as reading literature. We have used Ted Goldberg's (docent in social work at the university in Stockholm) theory. He writes that you have to be a significant other to persons with deviant behaviour to be able to help them become a part of the society and to change the way they look at themselves.

AbstractThis paper discusses how system development methods today support communication between system developers and their customers and end users. Today there are many system development methodologies with different aims and emphases. It is difficult, however, to find among these methods those who promote good and effective communication with customers because so many of these are very technically rooted and not as much directed towards the soft aspects of systems development - i.e. Human aspects. Our own experiences tells that a simple interview can be initialized without us having an idea what to ask the customer about or how to structure it up - nonetheless it?s done, but the outcome is just chance.

The purpose of this study was to investigate young teenagers 13-16 reading habits and attitudes concerning todays modern teenage literature especially written for the young teenagers. The study also includes the readers apprehension of the literature and how the target group is reached. The study is based on results from questionnaires, interviews and by compiling summaries of literature relevant to this study. Earlier research has been compared with results from this study. Reflections made by teachers and librarians concerning the youths reading habits are an integral part of the study.

This study is based on my work as a teacher of Swedish language and literature to upper secondary school students, and my interest in developing the teaching of literature by using both new criticism theories and theories of literary perception focusing on reader response. The purpose of the study is to examine the learning process in trying to develop literary competence and to find out how to describe the competence shown by the students. My starting-point is a discussion about literary competence and the theory and model of literary competence by Örjan Torell. In examining literary competence, by how students use their constitutional competence as well as performance and literary transfer competences, Torell´s model shows the possibility and the need for both knowledge of literature and personal reception by focusing on the dialogue between author and reader.The method is qualitative and the empirics are material collected in one senior high school class in the Social Science programme during their second and third year. The material contains written reading logs, written answers to tasks and transcribed recordings of discussions of literature.The analysis shows a variety among the literary competence shown and developed by the students and points to the complexity of understanding the concept of literary competence.

The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden. The students in focus were students with reading and writing difficulties, dyslexia or language difficulties such as an other native language. A total of eight students were interviewed. The interviews were analyzed using thematic analysis.

This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.

Ett av skolans mest utmanade uppdrag kan vara att upptäcka och arbeta med elever med lässvårigheter. Det övergripande syftet med den här översikten är att peka på hur modellen Simple View of Reading kan visa på de färdigheter som krävs vid läsning, svårigheter som kan uppstå och passande moment i arbete med dessa. Genom litteraturöversikten har nio nyutgivna internationella forskningsartiklar granskats för att svara till syftet. Översikten har sökt fokusera på inkludering av artiklar som endast behandlar yngre elever utan funktionsnedsättningar som adhd, apsperger, autism och/eller svårigheter genom tvåspråkighet. Alla artiklar i översikten är vetenskapligt granskade.

Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asset in today?s organizations, and it needs to be protected against both internal and external security threats. In our essay we aspired to find and present suggestions as to how systems developers can include security in the very design based on formalised systems development methods to create systems that are better prepared to meet the security challenges of today.

Den här uppsatsen handlar om vilket synsätt pedagoger, skolledning och den politiska nivån har på elever med läs- och skrivsvårigheter. För att ta reda på rådande synsätt på dessa elever har vi valt att göra en kvalitativ respondentintervju med sex pedagoger, två skolledare samt två personer från stadsdelsförvaltning. För att ta reda på vilket synsätt man har på elever med läs- och skrivsvårigheter. Vår studie syftar till att göra en empirisk undersökning för att skapa oss en bild om vilka rådande synsätt på elever med läs- och skrivsvårigheter som finns inom våra skolområden. Vi har studerat tidigare forskning och historik som kan ligga till bakgrund för rådande synsätt på elever med läs- och skrivsvårigheter.

The objective of the present study was to highlight preschool children?s encounters with children?s literature, in a heterogeneous language context.  The idea was to identify significant features in the linkages between the reading of children?s literature, didactic activities and children?s learning, language development and emergent literacy activities.  Our interest was directed towards the activities connected with read-alouds, as well as the preschool teacher?s perceptions of those activities.  The empiric material was collected by use of participant observations of four read-aloud sessions. After the observations the preschool teacher in charge of the observed read-aloud was in-depth interviewed. In addition, the physical print environment in the actual preschool was observed. The results indicate that the physical and social reading environment interact with each other.  Furthermore, the preschool  teachers? approaches and ways of working with literature does not always optimize the language, literacy and content area  learning opportunities for the children.

The automotive industry is increasingly studying lightweight solution in their designs, also rational production and low costs in materials and manufacturing methods are of great interest. This thesis consisted in the practical evaluation of anchors for sandwich panels. The object was to study loads of shearing and pull out of the plane. The experiments were carried out on panels made up of 1mm aluminium coatings and 50mm extruded polystyrene (XPS) at its core. As the fasteners used simple methods such as blind rivets, screw and glue.

The purpose of this Bachelor thesis is to gain insight into themeaning of the mobile library for its users by investigatingwho the users are, how they use the mobile library, why theyuse the mobile library and what the users want from the bookbus service. The methods used are observations, surveystudy and qualitative interviews.The theoretical framework of the study is based onAndersson?s and Skot-Hansen?s model of the public librarywith its four different library profiles, together with PierreBourdieu´s lifestyle theory where habitus and the concept ofcultural capital are used to analyze the role of the book busin people?s lives.My conclusion is that the mobile library is very important toits users since reading is an important part of their lives andit gives them easy access to books of several genres. Themobile library also functions as a meeting place in the localcommunity and creates a link between urban and rural areas..
