The aim of this thesis is to examine one part of Amazon.coms recommender systems: Similar Items. The purpose is also to show the difficulties with subject access, i. e. to find a similar book to the one you just read; problems with traditional systems versus the usefulness with recommender systems like Amazon.coms Similar Items. Similar Items presents a set, a cluster of related items to a given item based on customers co-purchase.

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Bullying is a widespread problem that currently exists in many places and in different age groups. In our paper we intend to focus on bullying in adult life. As many as 340,000 adult persons are subjected to victimization in the form of bullying, which is about 9 % of the working population. Between 100 and 300 cases of all suicides committed in Sweden can be linked to bullying. Bullying is a social problem that should be taken more seriously than it does.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

In this master thesis I investigate different views on literary quality in two quite different library journals; Biblioteksbladet and Bibliotek i Samhälle. One aim of the study is to see whether the ambiguity of the term literary quality is considered. Since there is no universally accepted definition of literary quality to be found the analysis is inspired by discourse analysis. This theoretical frame work starts off in the assumption that our views of the world are much dependent the way we describe it. The work of Finnish scholar Sanna Talja is presented and the results of this thesis are compared with the three perspectives on music culture that are presented in her book.

The Iron Age cemetery at Tuna in Badelunda parish, Västmanland, is a complex and unique burial ground used for only 69 graves during a period of roughly 700 years, between 300 - 1050 AC. The individuals buried at Tuna show an impressive variety of gravegods as well as stonesettings formed above the grave. Who where these people that were cremated at Tuna, among the mysterious women in the boats and the rich women in grave X? As we study the graves of the cremated individuals we reach a new understanding of the cemetery; from its social structure down to every individual. Through the analysis of the stonesettings, gravegods and bones we see a how these subjects, when analysed, show a picture of the individuals and social structure of the cemetery.

The Christianisation of Sweden is not much about religion. Instead, there is much to be gained by looking at it as a colonial situation with changing social identities and power structures. This is evident by the prevalence of hybridisations in the archaeological material.Some of the material categories that show the clearest example of changes are the burials from the 9th century up until about AD 1200. This is exemplified by two different Iron Age burial sites in Stockholm county, Uppland, Sweden: RAÄ 59, Valsta, in Norrsunda parish and RAÄ 40, Lilla Ullevi, in Bro parish; They both show hybridisation by involving older elements with newer ones during a time period when the church was not quite established in the region yet.The Christianisation of Sweden is a colonial situation, but the research tradition has often also used a colonial lens from the 19th and early 20th century in its approach to the period. This means that the same questions, interpretations and conclusions, often based on written sources, have been continuously reused for a long time, which has had consequences for the archaeology in Sweden..

This study is about how eurhythmic teachers create a comfortable and educational environment in their classrooms. In other words how they create a healthy working environment. Four teachers were chosen for the study, one of them male. I?ve used qualitative interviews because I believe it's the best method to collect information that illustrates what a teacher's working situation looks like and what he/she does to realize their own ideas.

Aim: The aim of this study was to investigate how women who have incurred ACL injury for more than 10 years ago, feel that the injury affects them today.Method: A qualitative semi-structured interview survey with five women who 10- 28 years ago incurred the anterior cruciate ligament injuries when playing handball or soccer has been performed. The study has been inspired by a phenomenological concept of science, mainly by life-world concept. Data were analyzed using qualitative content analysis.Main result: Some informants have experienced severe loss of physical ability in both daily living situations and in training, while others did not appreciably felt impacted in daily living and experienced great opportunities for physical activity. Limitations which emerged were restrictions in movement, joint stiffness, pain, swelling, and crepitations that led to the loss of physical ability. One respondent had been diagnosed with advanced osteoarthritis.

AbstractThe purpose of my study is to examine the experiences and opportunities to support teachers in preschool to help children in vulnerable environments, a good self-esteem. Hindberg (1999) writes that of all children today are growing up in Sweden, so ten percent live in families where there is abuse. According Pousette (2011) as the National Public Health Institute has a new appreciation for families where there is hazardous and this means that drinking or abused so much that it can become an addiction. They appreciate the investigation that twenty percent of all children in Sweden are growing up in these conditions.The results show that teachers' work is about building a sense of security in the children, both the teacher and the environment. It also shows that teachers believe that it is important to work with the self-esteem of all children, but especially children living in abusive families.

The purpose of this thesis is to analyze equalities/inequalities between the Danish and Swe-dish immigration policy based on Habermas theory about openings/closures and analyze the reasons to the differences between Danish and Swedish immigrant policy. Therefore this study has two question formulations, the first one was "Is there any equalities/inequalities between the Danish and Swedish immigration policy based on Habermas theory of openings and closings?" and the second was "Why are there equalities/inequalities between the Danish and Swedish immigration policy?" The results show that based on Habermas theory there are equalities between the Danish and Swedish immigration policy. On the question why, the re-sults show us that the factors who give the difference are work, people?s attitude to immi-grants and party politics.Keywords: Denmark, Sweden, Immigration policy, opening, closing..

The purpose of this study is to investigate the managers? perspective on leadership in relation to the motivation of the employees by an example of a manning and recruitment agencies. This is implemented by framing of two questions; What kind of leadership can be identified by middle managers to motivate their employees? Which motivation factors are relevant to employees based on the perspective of the managers? To answer the question and identify leadership strategies and motivational factors and the relationship in between, we have conducted eight interviews with persons who hold a middle management position. Through a qualitative investigation we have been able to go into depth and had access to these managers reflections, thoughts and experiences.
