Sedan 1990 och fram till 2009 har en tredjedel av Sveriges biblioteksfilialer lagts ned. Vårt arbete syftar till att studera orsakerna till varför den successiva nedläggningen av folk- och filialbibliotek sker, en frågeställning utan entydiga svar. I arbetet diskuteras olika tänkbara orsaksfaktorer, fokus ligger dock på en fallstudie av Växjö kommuns omstrukturering av sin biblioteksverksamhet. Vi
This study discusses the image of Sweden and Swedish society in Swedish-language instructional material used in the Swedish-language course for immigrants (S.F.I.). As such, the main source material for this study has been different textbooks used as instructional material in the S.F.I. course from 1967-2005. Theoretically, this study takes its inspiration from the branch of discourse analysis kno
Introduction and aim: In SPECT imaging, the finite spatial resolution of the imaging system leads to a blurring of the reconstructed image. Consequently, counts originating from each point in the source distribution will be spread out over a volume in the reconstructed image, leading to spill-over of counts between different structures and distortion of the apparent activity concentration. This pr
Introduction: The purpose of this study was to develop a technique for automatic segmentation based on Fourier descriptors for separating smooth objects from the background in SPECT-images. The aim of the segmentation method was to be able to automatically outline kidneys in SPECT-images of patients undergoing radionuclide therapy with 177Lu-DOTATATE. The potential advantage of combining SPECT- an
Purpose: The main purposes of this study is to a) evaluate the suitability of a Varian aS1000 EPID as a safe quality assurance device for control of machine specific parameters, such as linac output, beam quality and beam symmetry, and b) to investigate the usefulness of the SPC concept for evaluation of the obtained data. Method and Materials: Measurements were performed using a Varian Clinac 23
Radiochromic film, polymer gel and radiochromic plastic are three different kinds of dosimeters developed for radiation therapy. Even though all three types of dosimeters are suitable for optical scanning, the proposed readout method is different for each detector system. In this study, the scanning properties of three optical CT scanners were investigated to determine if they could be developed i
Diffusion MRI is an imaging technique capable of inferring information about the tissue microstructure, based on magnetic resonance imaging (MRI). Diffusion MRI data can be analysed using tractography, a tool able to represent the structure of the white matter (WM) in the brain. Tractography is commonly used qualitatively, but in this report, an algorithm for quantitative tractography was develope
Diffusion tensor magnetic resonance imaging (DT-MRI or DTI) is an imaging technique that is sensitive to the diffusion movement of water contained in tissue. It is used to quantify parameters such as the diffusivity and its directionality. Because diffusion is intimately connected to the tissue microarchitecture DTI is one of the few techniques that can quantify tissue microstructure non-invasivel
Breast tomosynthesis (BT) is a new X-ray modality that reconstructs the breast volume in many slices instead of, as in mammography, showing a single 2D projection of the breast. The slice thickness is typically 1 mm for clinically used BT-units. In screening the review of breast images with BT takes two to four times longer than the review of mammography images. In an effort to reduce the review t
Introduction: Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique for assessment of perfusion. ASL uses magnetically labelled blood water as a diffusible endogenous tracer to measure the perfusion of brain tissue, i.e. the cerebral blood flow (CBF). Traditionally, ASL samples images at a specific point in time allowing the CBF to be calculated using a model o
The purpose is to investigate whether the correlation between equity returns and changes in CDS spreads is stronger for sub-investment grade companies than for investment grade companies in the European iTraxx indices.
The thesis is an attempt to investigate the use of “informal justice as a political method” ( or “IRPM” in short) by the two Swedish right-wing organizations “info14/Fria Nationalister” and “Svenska motståndsrörelsen” using the organizations’ own web-published material for the period of 2000-2009, and to put the organizations’ use of “IRPM” into a Swedish empirical context. The thesis goes about
This study aims to find out the factors that could affect a firm’s RP transactions considering different social situation, extent of economic development and other culture factors. We examine related party transactions of the listed companies in China which stands for the emerging markets and in the U.S. which stands for the developed markets. We expect the conclusion that factors such as firm siz
MC, Machine Corporation, although historically successful is facing challenges as the industry in which they operate is matured. They thus need to find new ways of generating revenues. The service and parts market penetration rate decreases in the Danish market as the machine ages, but the need of service and parts increase why we argue that there is a market potential not being exploited as of to
Purpose: To investigate how consumers understand free services on the Internet. Theories: The research is primarily based upon theories of gift giving. Methodology and analysis: The Internet is not a tangible marketplace and in order to understand the value of the free services online, we used consumers' behavioral accounts to explain how they perceive the free services that are common online.
Syfte: Det första delsyftet med uppsatsen är att undersöka om fonderna i vårt urval har presterat under en 10 års period. För att mäta prestationen har vi använt oss av Sharpekvoten, Treynorindex samt Jensens Alpha. Huvudsyftet med undersökningen är att undersöka om prestationen sedan kan härledas till fondernas organisatoriska egenskaper. Resultaten ska kunna ge bättre vägledning för privata inve
The purpose of this paper is to make a personal reflection of the last year when I have been studying the Master’s Programme in Entrepreneurship at Lund University and the experiences I have had during this time. This paper mainly explores the importance of legitimacy and what you need to do to adapt and maybe change to fit in on a market but also the importance of trust, both within your own orga
The purpose of this study is to gain a deeper understanding about the consumption of contemporary charity in Western society on the example of the Swedish breast cancer charity Rosa Bandet. The study reveals exciting nuances of contemporary charity consumption, among them the glamourisation and disarming of cancer, the commercialisation and merchandisation of charitable giving, the changing role o
Sammanfattning: Syfte: Syftet med detta examensarbete är att förklara hur revisorer ser på risk när de bedömer potentiella klienter. Metod: Ett positivistiskt angreppssätt och en deduktiv ansats, med en kvantitativ metod, har använts för att nå fram till resultat för analysen.

Public Private Partnership, PPP, is a public procurement method involving the private sector used in several countries all over the world, now upcoming in Sweden. The UK, most prominent within this method, states that it offers good value for money, but the economic and financial benefits of PPP are still uncertain and subjects of debate. In order for the projects to be successful and to achieve v
