Adaptiv stämning : En bedömning av acceptabilitet och tonkvalitetsuppfattning
This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the standardized western tuning, the equal tempered tuning. This study investigates preferences for these two musical tuning systems, depending on whether the tunings are presented on a piano or with woodwind instruments. A listening test was done with students at the Falun Conservatory of Music, including both a vertical listening (intervalls) and a horizontal listening (cadenses and musical compositions) of Hermode tuned musical material. Overall the results showed no significant preferences for either tuning system irrespectively of what instrument it was presented with.
Den viktiga barnlitteraturen : Om förskollärares uppfattningar kring normkritisk barnlitteratur
The purpose of this study is to find out what preschool teachers think about antisocial children's literature. Based on five qualitative interviews with teachers at a preschool that works with a standard critical approach. In order to fulfill my purpose with this study, I focused on how these teachers felt that it was important to use the standard critical children's literature in preschool. I wanted to find out what the teachers' thoughts were on the concept of standard critical children's literature and how and whether they use it in their daily activities. When I analyzed the results of my interviews I used the queer theories that include standard critical pedagogy and literature in preschool.
När strategi blir design : Företags drivkrafter bakom grafiska profilbyten
Graphic profiles are a part of companies? brand expressions. The graphical values reflect the brand values the business wants to convey. They consist of different graphic elements such as logo, company sign, colour schemes, templates, rules, fonts, pictograms, formats and references to how different graphic elements should look, for example, business cards, signs and materials for websites. This thesis aims to examine why firms choose to replace their graphic profiles by studying their underlying motivations.
Bedömningsunderlag för användning av restprodukter i
vägbyggnad: med fördjupning inom aspekten ekologi
Traditionellt sett har vägsektorn främst använt jungfruliga resurser som konstruktionsmaterial. Intresset för alternativa material ökar dock och detta leder till att det blir allt vanligare att restprodukter används som konstruktionsmaterial.´ I dag saknas det enhetliga modeller, med allmän acceptans, för att bedöma en restprodukts lämplighet som konstruktionsmaterial i vägbyggnad. Detta innebär att det i varje enskilt fall tas fram ett bedömningsunderlag som anses vara lämpligt. För att bedöma ett materials lämplighet bör ett faktaunderlag inom en rad olika aspekter samlas in. De aspekter som kan vara aktuella kan delas in i Användning och Omgivning.
Kvinnligt+flicka/manligt+pojke=traditionella könsmönster : en semiotisk bildanalys av grundskolans tidigare års matematikböcker
This essay focuses on the pictures in mathematics books for elementary school. The purpose was to see if images in mathematics books for elementary school show traditional gender roles.The aim of the essay has been broken down into following research questions:Vilka färger förknippar de olika matematikböckerna till pojkar/män respektive flickor/kvinnor?How many times were girls/women and boys/men illustrated in the mathematics books?What behavior is associated with masculinity and femininity?Which colours are associated with boys/men and girls/women in the mathematics books?I used a semiotic image analysis method to study the pictures presented in the mathematics books. The theories in this essay were used to see how society makes girls become girls and boys become boys and in what ways the genders are portrayed in relation to each other. In addition, the theories include the question of whether a specific colour is given to a specific gender? The analysis evidently confirmed that the images in the mathematics books demonstrated traditional gender roles.

"Barn är viktigare nu på något vis" : En kvalitativ studie om hur fem pedagoger resonerar och praktiskt arbetar med barns inflytande och delaktighet i förskolan
The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.
Modersmålsundervisning, läs- och skrivutveckling i Sameskolan : Lärares erfarenheter och arbetsformer
The overall aim of the study was to take part of teachers' experiences and work force mother-tongue education and literacy development in the Sámi School. The study was conducted through interviews with twelve teachers who teach at two Sámi schools. The focus has been on looking how to work with native speakers teaching at the Sámi School, what factors promote / hinder students' development of their first or second language, and the importance of collaboration between the schools` various professions work with multilingual students reading and writing skills. Through interviews of various categories of teachers, I have tried to visibility problems of the education of minority language children and their reading and writing skills. I discuss the teaching, the importance and the lack / availability of communication and consensus between different categories of teachers.

Effektiv provningsmetodik för växelföringsdamasker
Completed durability testing of gearshift gaiters at Kongsberg Automotive in Mullsjö, is sometimes leading to discussions regarding whether or not a gaiter is supposed to be a pass or a fail. That is because the current pass/fail-criterion are a bit vague. A durability test takes around 4-5 weeks to complete which is a long time if the tested material does not pass the test and a new material has to be tested instead. Stricter pass/fail-criterions and a faster testing method for the materials are therefore desired.In order to develop a durable pass/fail criteria, seven already judged gaiters were chosen. Every one of the gaiters was put through detailed analysis, after which there were a new assessment of the gaiters.
Representeras ditt yrke? : - en kvantitativ studie om vilka yrken som representeras mest respektive minst i facktidskriften DIK-forum
The aim of our study has been to see how DIK-forum represents the occupational groups that are represented in the frames of the trade journal. We have, to find out the phenomenon, done a content analysis by looking into 18 numbers of DIK-forum from year 2006 and 2007. The 18 strategically chosen journals was enough to give us a statistic result that we later on could generalize over those two years of DIK-forum. Totally there were 818 articles, news items and vacant advertisements that made the central point of this study. By these materials have we studied the representation of the occupational groups to find out if there were any over- and/or under represented groups, and also if the publications of the material were directed to the students or to the occupational groups in these trade journals.In our study the results shows that the trade journal DIK-forum does not represent all the occupational groups at the same level.
