The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.

In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

The aim of this study was to conduct an instrument test of the Canadian questionnaire Alberta Context Tool (ACT) version Long-Term care for Swedish conditions. ACT is designed in order to measure the context in the care environment and different behaviours related to the changes in clinical practice. In total, 159 Licensed Practical Nurses (LPNs) and Registered Nurses (RNs) within municipality care of the elderly were included in the survey. The test included the instrument's reliability and face validity.The reliability test was implemented through calculation of Cronbach´s Alpha, and showed internal consistency for five of the scales of the ACT-instrument with Cronbach´s Alpha values ranging between 0,728 and 0,873. However, three dimensions got lower values (0,558 - 0,683).The analysis was carried out with content analysis and carried out for LPNs and RNs in separate groups.

In this thesis swedish students? worldsviews, in relation to the theory of evolution, were studied. Thirty students from two different schools and cities took part in the survey and four students were later chosen for interviews. The results showed that there are many different types of students and categories in this matter. The study also showed that for some religious students, accepting the theory of evolution was not difficult thus showing that religious students can both believe in God and in the theory of evolution..

This paper deals with the question of neolithisation of Southern Scandinavia. The main goal is to give an overview of three theories regarding how agriculture and livestock breeding was introduced to the Southern Scandinavia. These are as follows: the immigration theory, the socio-economic theory and the historical explanation theory. Furthermore it is investigated which theory has the most probably support in material culture. There are obvious difficulties in interpreting the archaeological material.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

The purpose of the essay has been to examine representations of immigrants in contemporary library and information science research in a Scandinavian context. By analyzing nine articles from the past decade we examine the perceptions that exist in the concepts of multiculturalism, culture, race, ethnicity, religion, gender and whiteness and what role and importance the library as a place is assigned in relation to immigrants as a user group. Our study consists of a qualitative text analysis, a critical oriented close reading method based on critical race and whiteness studies and intersectional theory. We have, with the help of Sara Ahmed´s theories of hegemonic whiteness, demonstrated how multiculturalism is partly presented as something desirable and good, partly as something potentially threatening.The discourse of multiculturalism can be said to express the notions of the other, which in the source material manifests itself by ascribing otherness to immigrants. We have, for example, examined how ethnical and cultural differences are highlighted by a separation of East and West, the library?s educational and assisting role in relation to immigrants as a user group as well as representations of whiteness, gender and clothes.

With this study we aim to learn more about the process in creating an identity onFlashback Forum. We have observed four members of the forum to find what themesdefine thier way of making an identitity. Besides to our empirical material we foundearlier research that could support our study. The methods we used was qualitativesince we wanted to get a deep understandning for their behaviour. We found thattheese three themes were central: Language, Content and the feeling of beingAnonymous.

Background: In Sweden and Norway planned home birth is not included in the health care system. In Denmark women with expected low risk birth have the right to choose home birth. Registrations of home births in the Nordic countries are not completed and women?s experiences of planned home birth in Scandinavian context are not earlier described.Objective: The aim of this study was to describe women?s experiences of planned home birth in the Scandinavian countries.Design: Inductive content analysis. Fifty-three Scandinavian women who have experienced planned home birth have replied an open question in a questionnaire.

Although textbooks are scientifically proven that they are important and central to the school curriculum one should think critically about the content in textbooks - is it really compatible with the curriculum of following the textbook tradition? As a teacher there are different ways to reflect on which textbook to choose. It is important to compare several textbooks with each other and be aware that a textbook should follow the curriculum. A teacher examines many sections/topics in the textbooks, but in this paper only one section will be reviewed among four different textbooks. The section to be compared, in the paper, is the interwar period.

University of VäxjöSchool of Social SciencesBachelor Thesis in Political ScienceTitle: ?Sverigedemokraternas valframgångar 2006 ? En ulv i fårakläder??Author: Emma Haraldsson and Åsa NeuschützTutor: Emil UddhammarThe aim of this study is to explain Sverigedemokraterna?s electoral success in 2006 and the essay assumes that some form of change has occurred. To study this change two hypotheses have been constructed. The first hypothesis concerns the change within Sverigedemokraterna and the second hypothesis concerns the change of the Swedish voters attitudes.Kirchheimers catch-all theory is used to explain the change in Sverigedemokraterna. The catch-all theory states that parties have to change their structure to maximise the number of votes.

This essay presents an alternative approach to the predominant democratic analysis of the European Monetary Union. As the Treaties stipulate the political conduct within Monetary Union and put certain restrictions on the European politicians they are to some extent constitutional in their character. Essential for constitutional theory is the concept of precommitment; according to which a decision is made in t1 purposing to obstruct certain actions in t2. In light of this the aim of this essay is to investigate whether or not delegating monetary responsibility to the ECB can be seen as an example of constitutional precommitment and if so, if this constitutional perspective can add something to the predominant democratic analysis of the EMU. According to the author the EMU is by and large a form of precommitment as the leading politicians in Europe figuratively have tied their hands from intervening in the common monetary policy.

The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.

I denna studie testas tio hypoteser som relaterar till finansiell teori för att se hur väl teorin kan förklara skuldsättningsgraden i små börsnoterade bolag. De teorier som testas är avvägningsteorin (trade-off theory), hackordningsteorin (pecking order theory) samt teorier relaterade till asymmetrisk information och agentkostnader. Testen genomförs med multipel linjär regressionsanalys och de undersökta bolagen är samtliga bolag med färre än 200 anställda på tre av de mindre börslistorna i Sverige. Resultatet visar stöd för åtta av de tio undersökta hypoteserna och är i flera avseenden tydligare än i tidigare studier som testar onoterade små bolag eller ett bredare urval av bolag..
