Expansion av sökfrågor med Svenskt OrdNät som termkälla
The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.

Det smarta kapitalet : En studie av nyetablerade IT-företags syn på relationen till sitt riskkapitalbolag

How important is their influence in the portfolio company's decision making process? Purpose: The purpose of this study is to give a deeper understanding of the relation between venture capital firms and IT companies in the start-up phase.
Metodutveckling av självskattningsformulär för prestationsmätning av flygledare innan skiftstart
This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.
Barnperspektiv inom socialtjänsten : En kvalitativ undersökning av socialsekreterares hantering av barnets bästa

Ett barn som alla andra? : En intervjustudie om familjehemsföräldrars uppfattningar om etnicitet
This study aims to examine how the interventions for homeless persons in the municipality of Kalmar are organized. The study is based on four half-structured qualitative interviews with both representatives from different instances and also from persons who have experience of being homeless.The theoretical bases we have used to analyze the material are organization theory, specifically the concept of bureaucracy. Our results show that homelessness is not seen as a problem in itself, since the general view is that homeless people often have a complex problem scenario where drug- and alcohol abuse and mental illness are common.It is often the latter that takes priority in the interventions and the housing question is therefore neglected. We also found that social services do not have a satisfactory structure around the organization of the work on homelessness. They do not have any specific device in Kalmar that focus on homelessness issues with the result that the existing units are forced to take care of the work of homelessness.
