Automatic query expansion has long been studied in information retrieval research as a technique that deals with the fundamental issue of word mismatch between query and document. The purpose of this thesis is to compare the retrieval effectiveness of different strategies for automatic query expansion. The strategies are based on local analysis of the corpus and use statistical information from the local document set to extract terms that suppose to adapt themselves to each individual search and therefore appear to be searchonyms to the index terms. The strategies compared are: association clusters, metric cluster and scalar cluster. Baseline queries of 24 topics are expanded using terms from the different clusters and searches are made.

With good knowledge about the disease and the treatment, the fear and worry of children and parents can be reduced. Children may be helped by painting to express their experiences. In order to have a good care, the care-personnel need to see and understand what the children need. It is important to live an as regular life as possible during the disease and its treatment. The aim of this study was to elucidate how children experience chemotherapy in conection with their cancer disease.

During recent years, the trend of Swedish students? negative performance and results in mathematics has been discussed. It is agreed that a change in teaching methods is necessary in order to solve this issue. Thus we found it interesting to take a closer look at an alternative way of teaching. The purpose of this study was to find out what teachers and students associate concrete mathematics with and make a comparison between them.

I detta arbete har samband mellan personlighetsdrag definierade enligt Femfaktor-modellen gentemot strategier för lärande och erhållna betyg undersökts.  53 gymnasieelever på naturvetarprogrammet samt 6 lärare deltog i studien. En tidigare rapporterad association mellan höga idrottsbetyg och extraversion (t.ex. hög självsäkerhet, mera utåtriktad, mer spänningssökande) var statistiskt signifikant även i denna studie.  Två andra personlighetsdrag, vänlighet/värme samt känslomässig stabilitet, visade även signifikans, p<0,05, gentemot höga betyg i biologi/kemi. Hypotesen att lärare tenderar att ge högre betyg till elever som har likande personlighetsdrag som de själva kunde inte verifieras i denna studie. I studien fanns exempel på lärare som gav högsta betyg till elever vars personligheter i vissa avseenden var motsatta lärarens.Då personlighetsdrag ställdes gentemot lärande, både i enkät och intervjuer, pekade resultaten på att elever har olika strategier för att underlätta sitt lärande och det som fungerar för en elev kan vara ineffektivt för andra. Detta understryker vikten av att läraren varierar undervisningen så att inte bara en strategi för lärande premieras..

This master?s thesis aims at examining and structuring different viewpoints concerning the assignments of the Swedish public library system. The method used is ideology analysis.The main questions are: what are the overriding goals connected to each of the different assignments? How are these goals motivated? By which means are the goals to be reached? And how does our analysis relate to earlier research on the assignments of the Swedish public library? The thesis can be said to consist of three main parts. Part one is a theoretical framework introducing the concept ?ideology analysis? and the concept ?schools of thought?.

This is a discourse analysis of three WebPages which topic is sexual information. Our purpose is to examine the WebPages RFSL (The Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights), RFSU (The Swedish Association for Sexuality Education) and UMO (Reception for young people) from a queer theoretical perspective and illustrate how they discuss the subjects? gender, sexual preference and sexual limits. Our questions are; what information about gender, sexual preference and sexual limits are presented on the WebPages RFSU, RFSL and UMO, and what similarities and differences can be identified and how can these be analyzed from a queer perspective? Our material was collected from the three WebPages and categorized according to three topics of interest; gender, sexual preference and sexual limits.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.

This essay aims to broaden the understanding of intolerance towards people with religious and/or cultural Islamic association or background. This thesis has intolerance and Islamophobia as central components and starts with the question: In what manner do twelve pupils talk about Islam and Muslims in their third year of the vocational program, in small towns and in the countryside? The survey took place in the south of Sweden in a rural municipality where a total of twelve students from the industrial, electricity and vehicle program in the Swedish gymnasiums participated in two separate focus group interviews. The essay will use an intersectional analysis to see where the students position themselves and Muslims in relation to each other and to society. The essay also contains a comparison of Islamophobia in the country side and in the city environment.

States have sovereignty in deciding how to tax business profits. If two states wish to tax the same profit that belongs to the same taxpayer, double taxation will arise. The increasing number of multinational companies gives rise to double taxation problems and the states have to co-operate to find out how to avoid such problems. The OECD Model Tax Convention includes an article in how to determine the rights to tax business profits. This article has been a subject of discussion and a committee of the OECD has been working to develop a new article 7.The work in proposing this new article has had as its aim to reassure that the interpretations of this regulation is made in the same way.

In 1985 the Swedish Association of Local Authorities and Regions published a paper on recommended depreciation time on capital assets for the public sector. This paper should only be seen as guidance, but many municipals use it without any further investigations. Swedish municipals are not like private companies; one very distinguished difference is that they are not allowed to make any profit. The municipals in Sweden are regulated by the constitution law which means that they can not go bankrupt. The public and the private sector have different legislations that result in different ways on how they for example treat depreciations.

The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.
