The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

The information technology development that has occurred over the past decade has broughtmajor changes into people?s lives. We have gotten used to being constantly connected to theInternet and always having access to information through mobile technology. This has led tochanges in education and more and more courses have become available through Internet. Theseweb-based educations are nowadays very common in schools and in the business world as theyprovide increased flexibility for the user.Habiliteringen Lundbystrand has seen the potential in this kind of education and believes this isan opportunity for them to rationalize their work by replacing parts of their education for parentswith a web-based education.

The purpose of this Master's thesis was to examine how and what trainee teachers are being taught about information seeking and school libraries related to problem-based teaching method in compulsory school. The questions at issue were: How have trainee teachers learned about information seeking? How have trainee teachers learned about using school libraries? We also wanted to know which education they have got in information seeking and school libraries. We examined this through both literature and empirical studies. We used a qualitative method in order to answer the questions at issue.

The purpose of the study was to examine how exercise of authority social worker´s view and work with normality has changed. Together with the role of changes in society, as LSS (Act concerning Support and Service for Disabled), user influence and the principle of normalization had in this context. The material has been collected through a qualitative method with semi-structured interviews which were held with eight social workers. Three of them had not been active within the field of this study for more than ten years and five of them are currently working. The collected material was analyzed through the theoretical perspective social constructivism and the theoretical concept case management.

The purpose of this Master?s thesis is to study how well the online catalogue of The Music Library of Sweden works when ordinary users are searching for sheet music. The issues studied are: Why do the users fail to find the sheet music they are looking for? Do the users take advantage of the possibilities that the classification codes of the SAB system offer? If not, why?The source material of the study is 144 comments from a user questionnaire about the online catalogue and, in addition, the search log for one day (513 queries). The comments were sorted into seven groups depending on the type of information need, for example searches for certain instrumentation or genres and problems with spelling.

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

In relation to the development of IT-products it is very important that the software supplier is aware not only of the target group but also the field of application. Usability should characterize the whole IT-design process as, in relation to this context, design includes more than merely those aspects which are visible to and thus can be interpreted by the naked eye. The study examines the specific qualities and properties that substantiate the usability and the demands that a customer rightfully expects from an IT-product. The user and the customer are highlighted in the same context in order to demonstrate that it is through the customer that an IT-product is defined as being useful. Thus, from this perspective, the user and customer can be considered as being the same person.

Boverket har huvudansvar för att skapa en portal för samhällsplanering som ska kunna förse kommuner, landsting, företag och privatpersoner med olika typer av kartinformation. Denna portal kallas Planeringsportalen och som ett led i dess utveckling hölls ett designmöte i april 2007. Inför mötet gjordes en analys av diverse förebilder för att beskriva de goda designlösningar som finns i genren WebGIS, enligt förlaga från Lundberg, Holmlid och Arvolas (2007) arbete. Uppsatsen beskriver hur dessa designlösningar kan användas i designen av Planeringsportalen tillsammans med en redogörelse för hur förebilder kan bidra till en bättre designprocess. Genren representeras i arbetet av webbplatserna Eniro, Norge digitalt, RATP samt Mapquest som alla studerats enligt ett formaliserat förfarande.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

The purpose of this Master?s thesis is to perform a user oriented evaluation of the International Library?s website. The questions posed in this study are; for what purpose do the users in this study turn to the International Library?s website; what does the users information searching process consist of when visiting the site; how does navigation, layout and content effect the users satisfaction with the website; do the users in this study consider that the International Library?s website can be improved and if so, how? The study was performed with a user oriented approach where six qualitative interviews with librarians who use the website were conducted. These interviews were analysed using Brenda Dervin?s Sense making-theory and Leclercq?s theory about user satisfaction.

The purpose of this essay is to identify how the drug user is portrayed in motion pictures. My main questions are: How is the drug use described? How is the male and female drug user depicted? How may the movies contribute to the construction, reproduction and change of gender? The method I use in my research is a qualitative, selective discourse- analysis of a number of movies prominently portraying drug use. A gender perspective is also applied on this paper.The main result of the study is that I have found that the great majority of the analyzed films portray drug use as means for something else. Drug use is often portrayed in the beginning as heavenly but changes to be depicted as problematic.

Bakgrund och problemformulering - Vi har valt att studera och analysera i vilket avseende det sker user innovation på ett forum skapat av företaget Salesforce. Forumet är ett brand community för användare som utvecklar Salesforce tjänster. Frågeställningarna behandlar om det sker olika typer av user innovation och vad det är som driver användarna till att innovera på det forum vi har valt att studera. Vår studie syftar till att bidra med en bredare kunskap och förståelse kring ämnet då det finns begränsad forskning kring user innovation inom online brand communities idag.Teori - Begreppet brand communities förklaras utifrån Muniz och O?Guinns (2001) synsätt som innebär att ett online brand community är en samlingsplats på internet dedikerat till ett specifikt varumärke.

The aim of this Master's thesis is to examine the contemporary educational tasks of the Swedish public library as they manifest in Swedish library journals. Our main question at issue is: Which educational discourses are there? And in relation to our main question: how do the concepts of information literacy, lifelong learning and adult education relate to each other? Is there an antagonism between the public library's duty to supply fiction as opposed to non-fiction? and: What are the consequences of these discourses in the service provided by the library?Our theoretical starting-point is the discourse theory as proposed by Ernesto Laclau and Chantal Mouffe. We analyse 39 texts from four Swedish library journals: Ikoner, bis, DIK-forum and Biblioteksbladet. The analysis is done in two phases.
