En komparativ litteraturstudie av olika termkällor för query expansion

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

Pedagogiskt arbete på folkbibliotek. En hermeneutisk studie av Biblioteksbladet under trettiotalet, sextiotalet och nittiotalet.

The aim of this masters thesis is to examine how the educational work of the Swedish public library was regarded in the Swedish library journal Biblioteksbladet at three different periods of the twentieth century, i.e. the thirties, the sixties and the nineties. Using a theoretical framework from the field of professionalization and a methodological framework of hermeneutics, it is shown that the educational work of the thirties can be described as having a focus on free learning whereas the educational work of the sixties can be described as having a focus on public utility. The educational work of the nineties focuses on the information seeking process of the user. It is noted that this development during the century can be understood as a shift of the cognitive authority of the public librarians.

Stabil växelkurs och låg inflation - Inbördes oförenliga? En studie av implikationerna av en real appreciering

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

Leadership is largely characterised by emotional communication, which together with personnel costs were the main focus of the research.

Risk för bostadsägare - en analys av risken vid förändringar av ränta och elpris

Since 1996 the Swedish households have ten folded their volume of loans for own homes that is attached to a floating interest rate. Also in 1996 the Swedish electric market was deregulated. These two facts have increased the volatility in the household expenses for these two commodities. This thesis studies the risk for homeowners attached to the exposure against the electric and the credit market.

?Det känns som en barnavdelning, det är ingen ungdomsdel liksom?: Ungdomar och det egna biblioteksrummet

The aim of this bachelor thesis is to find out how young adults experience the library and the space that they have access to. I used semi-structured interviews to find out about this and interviewed eight youths between the ages of 15 and 18 in a medium sized city in the province of Västra Götaland in Sweden. I then analyzed the material with the help of Goffman?s theory about front stage and back stage. I also did a small comparison with results from previous studies.The result showed that the youths generally liked the library and the staff but they had opinions on some issues.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

En bibliotekshermeneutik : Om skrivandets förutsättningar i Martina Lowdens Allt

This paper analyzes Allt, Martina Lowden's novel from 2006, from a media discursive perspective. The theoretical framework consists of Michel Foucault's discourse analysis, Friedrich Kittler's research on hermeneutic reading, and N. Katherine Hayles's studies of pattern?randomness controlled meaning production. Various examples on how communication technology influences the narrator?s act of writing illustrate the medial discourse surrounding the body of Allt.

Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

Lövsuccessioner i sluttningar längs nedre Umeälven :

Secondary deciduous forests, which have their origin in earlier pasture- and meadow-land in slopes along the lower reaches of the Ume river, are thought to contain high nature conservation values, in spite of a relatively low age. The aim of this study was to clarify how factors as historical use, exposition, disturbance dynamics and successional age influences the conservation values in these types of riparian forests and how this can be implicated in the practical work with conservation and management at Umeå municipality. Sample plots were placed in seven stands with a variation of their historical use, exposition, disturbance dynamics and age of succession. Conservation values as structure, tree-regeneration, abundance and composition of vascular plants, amount of dead wood and the abundance of signal-species were measured and registered. The species composition and especially the composition of tree species, differed between forests with different exposition and different historical use.
