This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

The aim of this study is to describe and analyze how Bolaget, a paper published by the Swedish alcohol monopoly retailer Systembolaget, constructs issues of alcohol in 18 preventive articles published between 2009 and 2012. More specifically the essay focuses on the consequences of alcohol, as well as its consumers and functions. Systembolaget is a distributor of alcohol and at the same time has an assignment by the state to reduce alcohol-related harm. This double role makes the alcohol prevention of Systembolaget, and their perspective on consequences, consumers and functions of alcohol, an interesting object of study. The theoretical and methodological basis is Fairclough?s critical discourse analysis.

This report is a hermeneutic analytical study of a practical pedagogical situation. For three occasions I observed my own practice as a dance teacher and how a moment, choreographic approach in the governing documents for upper secondary school GY11 was executed in a group of dance students. The part is formulated in the course objectives for the courses on the arts program under the topic Dansgestaltning with focus on choreographic approach. The study is based on a socio-cultural thinking but also takes into account the prevailing gender theories and focuses on how the process of formulation level, through the transformation level is portrayed in the realization level of the dance regarding choreographic approach. The study illustrates educational research from both a dance perspective and a school development perspective.

The purpose of this study was to analyze how the key staff concept is used in residential care for children and young people and which role the key staff concept plays in the organization.The study was based on semi-structured qualitative interviews with six key staff and two managers from two different residential care facilities for children and young people. The theoretical perspective used was the neo-institutional theory and Hasenfeld´s term Human service organizations.One of the conclusions of the study was that the key staff describe that they have a central role when it comes to the treatment of the children. Another conclusion showed the variety of tasks that the key staff have, like the administrative work that they do. They also have an educational role, similar to the one that parents normally have which means that they are responsible of parenting the children. They also described themselves as a link between the children and their social network.

Purpose: To assess awareness and attitudes regarding HPV, HPV-vaccines, use of condom and participation in pap-smear screening among high-school students in Uppsala County. The intention was also to investigate if there were any differences between students at theoretical programmes and vocational programmes.Methods: 608 students from seven high-schools in Uppsala County answered a questionnaire covering demographics, awareness and attitudes regarding HPV, HPV-vaccine, use of condoms and pap-smear tests.Results: A majority of the students had never heard of HPV (86 %, n=521), HPV-vaccine (94 %, n=537) or the link between HPV and cervical cancer (88 %, n=563). Most respondents had a positive attitude towards HPV-vaccine (84 %, n=508), but the biggest obstacle was the high cost (37 %, n=227). The students believed that it was less likely that they would use a condom with a new partner if vaccinated (mean=78, SD=26, p<0.001), or if they or their partner used contraceptive pills (mean=62, SD=32, p<0.001) compared to how likely it was that they would use a condom in general with a new partner. The girls rated the probability that they would participate in a pap-smear screening as relatively low if vaccinated (mean=59 SD=27).

This study aims mainly to investigate what kind of role the public library plays in the regional and local development. The aim is also to investigate how the public library can strengthen the role as a factor of regional and local development. To explore the subject, the study is focused on the Swedish region of Västra Götaland. Three officials along with two policy documents, are included in the study as representatives of the region. Four public library managers are also interviewed but as representatives of the local perspective.

It is clear that media advertising is one of the crucial marketing tools for companies in order to promote their products and services. As we are moving towards more and more economic integration, both on a regional and global scale, the question about standardisation of media advertising has become increasingly important and is nowadays subject to discussion in most international companies. This thesis deals with the issue of standardisation in a region where the process of political, legal and especially economic integration is taking its course, but where cultural and linguistic diversity is still a remaining fact: Europe. The aim of this thesis was to investigate the potential gains from a standardised advertising approach but also to identify its limitations. Especially on a market place like Europe, with its diverse cultural and linguistic background, a fully standardised approach might be difficult to implement.

In Sweden today, more women are still going on parental leave than men. The number of men and women going on parental leave is more equalized than ever before. At the same time the inequalities are still big and more women than men choose to work part time up till the child is eight years old.The aim of the study is through a gender perspective, to investigate the preschool teacher?s thoughts about the daily meetings with parents and the contact during induction. The study is based on the theoretical concepts: gender, norms and gender equality as well as three questions.

The aim of this thesis is to examine the relationship between user education at high schools and the context in which it takes place. In order to accomplish this qualitative interviews have been executed with librarians at five Swedish high schools. The theoretical framework of this thesis is based on the sociocultural perspective and four approaches to user education developed by Olof Sundin. Based on the empirical material six themes have been identified. Each one represents a contextual factor which influences the user education.

The aim of this study is to examine how librarians experience implementations of changes in the physical space of the public library. The study seeks to answer the following questions from the librarians? perspective: What are the underlying reasons for changes in the physical space of the library? What are the important functions of the public library to the community residents? What reactions do librarians get from community residents after changes in the physical space of the public library? The study is based on semi-structured interviews with librarians working at seven small public libraries in Sweden. A model of four library spaces, which was developed by Andersson and Skot-Hansen in 1994 and refined in 2012, is used as a theoretical framework to help analyzing the results. The majority of the libraries are structured according to the older version of the model.

The view on which kind of fiction that should be mediated to the public through the Swedish public library system has since the late 60´s been dominated by what in this Master?s thesis is called: ´the discourse on quality of literary fiction´. The aim of this thesis is to examine to which extent this discourse still plays an active role in the Swedish public library system or if that discourse has been replaced by a more market-led, demand responsive view, where the features of ´quality´ and ´culture´ have been downplayed and replaced by a ´customer?s service view´ on how and why fiction should be mediated to the public. The methodological and theoretical perspective in this thesis is led by the understanding of the discourse analysis in Michel Foucault?s ´The Archaeology of Knowledge´.

The purpose of this essay is to analyze theories about positioning that will create an image of the positioning process, which we later on shall benchmark with other companies way to position their brand. By this, we want to obtain a well-documented work on how Luma Metall AB should work with the positioning on its brand in the future. This essay is based on a qualitative method that is characterized by an abductive approach. The empirical materials we have gathered through interviews with 5 selected persons that are well experienced on the subject have given us important information. We have come to a conclusion how a small company in a B2B market can position itself.

The purpose of this study is to find, understand and discuss the experiences of former employees at SAAB, and present how this can be understood according to my core theoretical concepts, which are participation and identity. The questions asked in the study are based on how the labor is described, characterized and what comes forth as valuable, which is compared to absence of labor work.First, labor is described in an historical and social context, and at the same time related to the core theoretical concept. Second, the methodology chapter is presented, which mainly consists of 11 observations and 10 interviews. Third, the chapter regarding former theory leads to an analysis model, which is used on the empirical material of the study.The result shows that labor work at SAAB primarily is described as important for socializing, security and the possibility to be independent. The tasks at SAAB are described as backbreaking and monotonous, while the lack of labor work influences the physical and mental wellbeing.

The aim of this thesis is to make a contribution to the field of design oriented theory, regarding young children and their way to digital competence. My research question is: How can a preschool with a certain pedagogical ICT-design give the children affordances for media play and for developing a digital competence?The European Parliament points out digital literacy as one of the Key Competences for life long learning. A digital competence is built on basic ICT (Information and Communication technology) skills. Skills you can develop any time during life, weather you are young or old.
