The goal of this essay was to study if the way gaming review sites presented their review evaluation has any influences the level of product involvement in the users it attracts. The assumption we did during the essay was that there was a connection between user?s level of product involvement and the quality of the community. To test this assumption we started out by performing observations on the comment sections in three gaming news sites which varied in their method for evaluating games. The result of these observations showed a significantly higher community quality in one of the websites.

Detta arbete är en variationsteoretisk studie i hur elevers lärande i naturvetenskap påverkas av undervisningens utformning. En så kallad ?learning study? utfördes med två grupper ur en femteklass. Grupperna undervisades i två omgångar med utvärdering och utveckling av undervisningsmaterialet mellan. Elevernas för- och efterförståelse kartlades med hjälp av intervjuer och grupperna jämfördes med avsikt att undersöka hur de olika undervisningstillfällenas utformning påverkade elevernas lärande.

Our study emanates from a socio?cultural perspective on learning and aim to describe and comparetwo different upper secondary school classes and their work with information literacy as a socialpractice in project work and their use of ICT (information and communication technologies). Thequestions at issue in the study are; how the pupils handle information seeking processes, whatdifferences and similarities can be observed in the two social practices and which consequences thesedifferences have in an project work environment.Our choice of research methods to collect data consists of both observations and interviews withpupils and teachers. The interviews performed in the study can be categorized as qualitativeinterviews, and in addition we recorded and took notes during the interviews and transcribed thematerial.The study shows the importance of a good learning environment when it comes to working withinformation seeking processes, that the instructor?s role is of outmost importance and that the pupilsfundamental knowledge of information seeking processes and their information literacy are keysuccess factors when it comes to project work linked to ICT to be productive.

Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.

Regarding school-teaching most people have had the traditional idea that the teacher is the owner of all knowledge and the student is the receiver of that knowledge. Tradition tells us that the way the student receives the knowledge has been by listening, repeating, reading and memorizing what the teacher has taught. Research about teaching from the last decades show that there are other strategies, ways, and qualitys for helping students in learning. One of those ways is by integration of different school subjects.According to research every human being creates her own knowledge based on personal experiences. Johan Krantz and Pelle Persson (2001) wrote that learning is a process with experiences, ideas and opinions.

The purpose of this thesis is, from a self directed learning perspective, to investigate the support of public libraries and genealogy associations of genealogists' own research, i.e. their search for ancestors as well as their possibilities to broaden their history outlook. Accordingly, five public librarians and five genealogy representatives in the west of Sweden have been interviewed regarding the support that can be offered to genealogists. The investigated support to genealogists in their own research is about working environment, literature and material, activities and the cooperation between public libraries and genealogy associations. In this thesis conclusions are merely drawn from a self-directed learning perspective, a perspective where also different forms of support are being recommended by scientists.

In school there are many pupils with Swedish as their second language and these pupils often have less basic condition compared with pupils with Swedish as their mother tongue and the most common root cause is lack of language knowledge, also the time spent in Sweden matters.I have trough questionnaires and literature studies investigated if there, for pupils with Swedish as their second language, is an easier way to figure out how to read and write in Swedish using fiction literature as learning material compared with ordinary ways.In the questionnaires that I performed participated a number of teachers that teach Swedish as a second language. These teachers all work in schools with a big share of pupils with Swedish as a second language.I also tried to evaluate if there was a difference between teachers with a graduation in Swedish as second language compared with these who don?t have a graduate but still work with these pupils.The result shows that I discovered that only the graduated teachers have used fiction literature as a learning material in the daily work and have experienced good results from the pupils, they also knew why they used fiction literarture for reading and writing training.As a teacher it is very important to have the knowledge regarding children that have Swedish as a second language, to be able to support them in a correct way.Despite the pupil can?t speak or read the new language, it has feelings and knowledge about the circumstances that they can?t express.The teachers mission is to knew and have understanding for these circumstances.Keywords: Pupils with Swedish as second language, learning to read and write, fiction literarture, school..

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

The aim of this thesis is to study preschool-teachers? experiences from using the computertablet as a tool for learning and teaching, in order to gain knowledge of how the integrationalprocess of information and communications technology (ICT) in preschool has progressedsince its instatement. The background that caused interest to make this study was the rapidprogression of the use of ICT-tools in childrens? everyday lives and the troubles that havesurrounded the process of integrating these tools into preschool-practices. The theoreticalbasis for the analysis of the research lies within the socio-cultural perspective.

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

When a person arrives at the emergency ward at the Uppsala University Hospital with his or her symptoms he or she explains the problems and then a priority process starts. The staff evaluate at which emergency level the patient is located in a model called Triage. The Triage model helps to decide the priority need and is based upon templates which point out in which of the 5 categories a patient is to be placed, to eliminate any future risk regarding his or her health. A lower triage level means lower priority but implies better health when the evaluation takes place. To obtain optimal effect of the Triage model the evaluation of symptoms must be reproducible so that patients with the same symptoms are placed at the same triage level regardless of whom among the staff conducts the evaluation. The purpose of the study was to see if the resources are allocated based on priority level of the patients.
