The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.

This paper aims to investigate abnormal returns for rivals to bidder targets in connection with the announcement of the bid. The study is based on 38 bids placed between September 2006 - January 2011 and 137 rival firms listed on Nasdaq OMX Nordic. We measure cumulative abnormal returns, CAR, for rival firms through an event study. We find that rival firms earn significant positive CAR in connection with the announcement of the bid. This is in line with the two-sided signaling effect presented by Akhigbe et al.

This is a case study that explores the ways in which implemented university reforms have affected employees in the higher educational sector. Previous research within the research field has mainly focused on policy related consequences of the reforms. This is why a study that brings attention to the ways the reforms have affected employees is sorely needed.The aim with the study is to examine whether there is a discrepancy between formal changes and the ways the employees experience them. The study is based on interviews with 8 lecturers from two universities and the material is analyzed mainly through sociological neo-institutional theories, such as Richard Scott?s theory of the three pillars within an informal institution and Helmke and Levintskys theory of the relationship between formal and informal institutions.The results show that there is a discrepancy between the formal changes and the ways employees perceive them.

Knowledge is frequently discussed in modern society, and has been since ancient Greece. Our goal is to examine the content of two political documents with the desire to point out their visions about how the Swedish school system should be shaped, in relations to knowledge. More precise this essay is going to concentrate on two specific political parties, Folkpartiet and Vansterpartiet and their official programs on the subject school and education, to see what they say about knowledge. The choice is made on the basis that these parties political standings differ most from each other, in the left/right scale in politics. The qualitative analysis takes its main base from Aristotels concepts of knowledge; Episteme, techne and fronesis, and Bernt Gustavssons modern defenitions of them.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
