Kanban : Går metoden att använda för att styra utvecklingsprojekt?
Kanban är en agil metod som härstammar från den japanska Lean-filosofin. Metoden fokuserar på att få ett flöde med så kort ledtid som möjligt. Det ska vara lätt att se flaskhalsar som bildas. Problemen ska sedan lösas innan något nytt arbete påbörjas. Kanban-metoden ska vara enkel och lätt att använda.Syftet med uppsatsen var att ta reda på om Kanban-metoden verkligen är en bra metod att använda sig av för att styra utvecklingsprojekt och om den bidrar till att stödja planering och information.

Det brutna kontraktet : Om den missförstådda genren dokumentärroman och vad som sker när kontraktet mellan författare och läsare upphävs
Abstract The topic of this essay is to show why I regard the non fiction novel as a problematic genre and to compare two popular and famous swedish non fiction novels; Legionärerna (1968) by Per Olov Enquist and Gömda (1995) by Maria Eriksson and Liza Marklund.I start with giving a short introduction to modern genre theory and to non fiction novels as a genre. I also discuss different definitions of non fiction novels by, for example, Rolf Yrlid and Lars-Olof Franzén. Then I discuss Enquist?s Legionärerna and the critics? reception of it. I am also doing the same with Eriksson?s and Marklund?s Gömda before I compare these two novels with each other. My conclusion is that Legionärerna and Gömda have a lot in common although there are some differences.
Självförfattning, läckage och olikhet : Om att kombinera kvantitativ metod och queera teorier i sexualitetsstudier
The aim of this study is to combine queer theories with quantitative methods. In social sciences, queer theories are being widely and increasingly used. Quantitative method is also widely used, and as a traditional method it can be regarded as a cornerstone in social sciences, sociology in particular. However, the two perspectives, queer theories and quantitative method, seem at a first glance to be very different in their understanding of social phenomena. Queer theories have, with some exceptions, mainly focused on qualitative research concerning such phenomena as sexuality, while the field of science is quite diverse.

Media och dess inverkan : exponering av idealiserade könsroller och dess inverkan på unga människor
The purpose of this study is to examine the impact that idealised body images found in media have on the body-image and wellbeing of young men and women. The study was carried out using questionnaires based on the BAQ and HAD scales to examine the participants' views of themselves as well as symptoms of anxiety and depression. Time spent by the participants using different kinds of media, as well as their degree of social support, was used with the purpose of examining relations and differences in body-image between men and women. The questionnaire contained advertising images to examine whether short time exposure had any impact on the participants. In order to determine this, one half of the questionnaires contained idealised body-images, whilst the other half contained images without human objects.

Det implicita avkastningskravet på Stockholmsbörsen: En jämförande empirisk studie med avseende på antalet börsintroduktioner för 1999 och 2012
This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..
Analys av vävnadsprover med endimensionell elektrofores
The following project has been made in collaboration with, Denator AB, a biotechnology enterprise. One-dimensional electrophoreses have been used to analyze protein contents of tissue samples. Tissue samples have been either treated according to the company´s newly developed tissue treatment technique or not treated at all and comparisons between these samples have been made. In order to see differences in protein patterns between samples more clearly, a conversion method has been developed where electrophoresis gel visual patterns are used to produce curves, similar to densitometer curves.Denator AB would like to know if the proteins in their treated samples will change visibly over 48 h when incubated at room temperature. This has been investigated using the above mentioned method.
Nationalbibliografin: en komparativ studie över musikområdet i Norges, Sveriges och Danmarks nationalbibliografier.
The national bibliography is an important tool in information retrieval. Bibliographies as lists of books have existed for centuries, but the national bibliography as we refer to it today, as a directory of the total national imprint, has only existed for about 50 years. The object of this thesis is to investigate music documents in Scandinavian national bibliographies. The method I have used for this investigation is a comparative study of the music departments in the national bibliographies in Norway, Sweden and Denmark. The investigation is performed by answering the following questions: How do Norway, Sweden and Denmark live up to IFLAs Guidelines and recommendations for the national bibliography? Can one discern any differences between the three countries in this area? The documents in focus are sheet music and phonograms.
