The purpose of this thesis is to compare five different ranking algorithms for query expansion. The algorithms compared are f4, f4mod, porter, wpq, and emim. This is done using a TREC collection, a selection of topics, and relevance judgements. Relative recall is measured before and after the expansion of the query. The study shows that all of the algorithms manage to increase the relative recall, f4 being the one most successful..

In this essay, I interview six users from the website darkside.se, which is an internet community for BDSM practitioners. I?m using Judith Butlers theorys about performativity and heteronormativity, Gayle Rubins model the charmed circle; of which sexualities is regarded as approved and which is not, and Fanny Ambjörnssons explenation of queer theory. With the interviews as my material, I investigate how sex and gender is produced and used in BDSM and at Darkside. I discuss trans, heteronormativity, sexism and hierarchies of power related to sex and gender, in BDSM and at Darkside.

For centuries inbreeding has been used to refine traits in dogs, making desired traits more hereditary and thereby, different breeds have been invented. Breed standards have been written for each of these breeds, describing in detail the different characteristics of each breed. When humans start to choose which animal to breed from, so called artificial selection, taste is put before function and the laws of nature, the natural selection, cease to apply. During this development, pedigree dogs have gone towards more and more extreme exterior characteristics and the dogs may have inherited various, more or less, severe problems for example compromised vision, impaired ability to move and difficulties to breathe. However they can still survive and reproduce because humans provide them with the conditions to do so.

Denna kvalitativ intervjustudie, söker en förståelse kring fenomenet sex som självskadebeteende. Självskadebeteende har studerats och definierats, men sex som ett självskadebeteende är inte inkluderat som ett begrepp i dessa vetenskapliga studier (Zetterqvist, 2014; Nock, 2014; Klonsky 2009). Däremot har psykologer, organisationer och andra professionella tolkat och definierat fenomenet som att det existerar (Sjöström, 2012; Landgren 2015; Jonsson och Mattson, 2013; Tjejouren 2015; MUCF, 2013). Genom intervjuer med tre olika personer som kommer i kontakt med sex som självskadebeteende, kombinerat med tidigare forskning, visar denna studie att sex kan användas som självskadebeteende och att det görs i syfte att hantera (coping) ångest och andra negativa känslor. Tidigare trauman och/eller en dysfunktionell familjedynamik kan leda till att en individ utvecklar icke fungerande strategier för att hantera potentiella dåliga känslor. Individerna vänder sig till sexuella destruktiva beteenden som en affektregleringstrategi.

The purpose of our essay is to investigate the trust in accountants. The method we used to investigate the trust was a survey and a questionnaire was used to collect the data. The data was gathered from three different groups, shareholders, lenders and tax authority. When we analysed the data we found out that the groups trust in accountants were neither strong nor weak. The results can be generalized on all the three groups because the observations were scattered around the means and we used random selection to collect the data.

Online dating and ?People nearby applications? (PNA) has become more popular in today?s society. With PNA you can easily find people who are nearby you that you can socialize with and maybe even meet.

We also had a group interview with five Badoo users about their usage of the application.

Nordic Summer Evening is a theoretical painting, today an important icon of Nordic art from the turn of the century. The purpose of this essay is to analyse the painting, and to investigate and identify its declaration of program, and in a wider context, the emergence of a program of the nationalistic art at the turn of the last century. The essay also investigates how the painting has become more popular throughout the century, and why Americans tend to see the painting as an exposé over a quarrel, filled with sexual tension, while Swedes tend to make a point out of the harmony and stillness of the painting..

The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Nina Johansson starts her essay by making some examples of dreams to show the diversity of the ?dream world?. She speaks of how all humans dream, that it ties us together. She wants to translate the ?feeling of dreams? into wearable objects, and to be able to do that, she must try and describe what that feeling consists of.

När det på 1990-talet uppmärksammades att barn kunde utsätta andra barn för sexuella övergrepp stod behandlingspersonal handfallna. Detta var något som det aldrig tidigare pratats om och ingen visste hur man egentligen skulle tackla problemet. Tack vare Rädda Barnen, Börje Svensson och Anders Nyman kunde ett behandlingsarbete utvecklas. Svensson och Nyman startade upp Rädda Barnens Pojkmottagning och tog emot både flickor och pojkar med sexuella problembeteenden. Efter att denna målgrupp uppmärksammades började så sakterliga utvecklingen av behandlingsmodeller.

Today endless choices exist for a customer in the grocery store in terms of information, products, brands and prices. Consequently, it is important for retailers and brand owners to gain insights in how they can manage to break through the clutter to reach the customer. Displays that include some kind of motion element are assumed to possess an attention grabbing ability, which is a necessary first step in influencing the customer?s decision making. Therefore we have explored whether so called dynamic displays are efficient in grabbing attention and influencing customer behaviour.

The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma. Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.

The purpose of this investigation was to study what students in in the first year of the social science program in high school think about the guidance they had access to during their time at primary school. This is to ensure that it the guidance students are entitled to and contribute to the development of the business. The survey was conducted at two different high schools in southern Sweden. A total of 57 students participated in the survey. The results show that 46 and 29 percent of students at the two schools did not feel they had the information they needed for their upper secondary school The results proving what previous research reached that students selection process can lead to stress and uncertainty associated with the choice to high school. The results of the present study showed that girls in particular have high standards for themselves and experience stress and anxiety associated with their selection to a greater extent than boys.

This masters thesis examines the reading environment during "booktalk", with special reference to a reading project in compulsory comprehensive and upper secondary schools in Stockholm. The main question is: What does the reading environment look like during booktalk? Three questions are asked: Which factors affect the reading environment? Which are the conditions concerning book selection and book availability? How do the librarians perform as enabling adults? Different groups of pupils, together with their teachers and the librarian, are studied during booktalks in five schools. The study uses a qualitative approach, which takes the form of open observations during 15 booktalks and one interview with the two librarians involved in the project and studies of literature. The theoretical framework is Aidan Chambers theory relating to reading environment and its effects upon the reading process.
