The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.

This essay is a philosophical investigation of the relation between children and their play. My aim is to see if children are autonomous when it comes to their play. Is there a moral boundary between those who take part in the play and those who do not? This topic is especially important when it comes to the moral status of a child in the Swedish pre-school. How should educationists act when it comes to children?s play?  Through an analysis of the notions of play and autonomy I show that play can be understood as something of a moral value to the child and if children should be seen as autonomous when it comes to their play.

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

The purpose of this Masters thesis is to compare the scheme structure of two national classifications system, namely the Swedish SAB system and the German ASB. It has been assumed that there are no major differences between the two models of classification systems or the main classes into which documents are placed. The classification theory and subject analysis, which form the basic theory on which my research is based, are taken from Dahlberg, Langridge and Rowley. A comparison of 30 monographs classified in the SAB system Sveriges allmänna biblioteksförening and in the German ASB system Allgemeine Systematik für öffentliche Bibliotheken showed that the classification structure was primarily responsible for determining where a particular document was placed. However, despite the fact that the subject in various documents may be similar, my research will demonstrate that the structure of the two codes also depends on different interpretations of the main subject in a document.

The aim of this paper is to examine the actualities of Information Practicefor single women whose parentage has been made possible through assistedreproduction, which places these parents in a norm-breaking position.Study issues related to parents? perceptions of information needs areinvestigated, as is the process of information retrieval and library usageas well as the obstacles and opportunities facing parents in search ofinformation related to their own family constellation. To this end, theoriesby Tom Wilson, Reijo Savolainen and Elfreda A. Chatman have been usedas a model of selection. Empirical data have been gathered from interviewswith eight single women, whose parentage has been made possible throughartificial insemination or IVF with sperm from an open or anonymousdonor.

The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.

Elektronisk affärskommunikation har kommit att influera den privata företagsamheten i allt högre grad. Syftet med denna rapport är att ta reda på hur den privata företagsamheten i Skaraborg använder sig av elektronisk affärskommunikation. Rapporten baserar sig på intervjuer som har gjorts med åtta privata företag inom skilda branscher i Skaraborg. Intervjuerna är uppdelade i fem olika delar, presentation av företagen, e-närvaro, e-handel, e-business samt för- nackdelar och övriga kommentarer.Resultatet som framkom ur undersökningen var att de undersökta företagen har kommit olika långt vad det gäller utveckling och användning av elektronisk affärskommunikation. E-mail och hemsida har nästintill samtliga undersökta företag, men hur pass stor del av de anställda som kan använda sig e-mail samt hur de undersökta företagen använder sig av sin hemsida skiljer sig markant..

This essay is about the engineer platoon. The engineer platoon has many different tasks and from my own experience sometimes too many. The platoon is able to build bridges, clear mines and to perform all kinds of construction work in rural or in urban terrain.In this case study I compare goals/demands for the battalion to goal?s set up for the company and finally what effects this has on the engineer platoons abilities. The main question is, if the engineer platoon really can solve all tasks given to them in the document TOEM? Abilities such as effect, protection and movement are the bearing parts of the case study.The materials I have analyzed are mostly from documents published by The Swedish Armed Forces.

Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites. The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.

The purpose of this thesis is to compare mass digitization and qualitative digitization, to see how the digitization process and the digitalized material differ. The study emanates from the mass digitization as it is performed at the National Library in Norway, and the qualitative digitization at the Royal Library in Sweden. The method used is document studies combined with mail interviews. The focus is upon the practical operation, to which counts: ?purpose & selection?, ?preparation, image capturing and processing?, ?metadata & text encoding?, ?quality assessment?, ?storage of digital originals and copies? and ?display?.

This two years master?s thesis in Library and Information Sciences aims to investigate and put the services of 118100 Svar På Allt (SPA, an SMS mobile question and answer service) and Fråga biblioteket (FB, a library operated e-mail reference service) into the context of the reference encounter. Questions sent to SPA and their subsequent answers are analysed, and part of these questions are forwarded to FB for comparative studies. Both of the formats are compared to the reference encounter as a whole. The framing of the question originates in the assumption that there may be a need for further negotiation of the questions submitted to the aforementioned formats.

I detta examensarbete undersöktes hur ett kemiprov inom området kemisk jämvikt utformades och bedömdes på en gymnasieskola i Mellansverige. De två lärarna som utformade och bedömde provet intervjuades och fick svara på frågor via e- mail. Både intervjudata och frågorna via e-mail kategoriserades med hjälp av Selgheds (2006) kategorier rörande synsätt på betygsystemet. Resultatet visade att lärarna har olika synsätt på både provets utformning och bedömning trots att dem tillsammans konstruerat både prov och facit. Lärarna täckte med detta prov flera av de kända missuppfattningar som den didaktiska forskningen funnit, även om det inte var på ett systematiskt sätt.
