The beta value is frequently described in theory and is a well known factor to quantify the systematic risk in shares through the CAPM model. Initially, this study describes the advantages and difficulties with the estimating process and the problematic nature of the assumptions and descisons included in published beta values.An alternative method, Bottom-up beta, to estimate the beta value that probably has not been tested under Swedish circumstances is applied. The problems and decisions that have to be made to derive an alternative value are studied in detail through six separate steps. I have chosen nine companies at the Stockholm Stock Exchange where this method is used. The result showed that the systematic risk were higher at five shares and lower at four, compared to the published values.Finally there is a discussion about the practise, usefulness and opinions concerning how to estimate and interpret the beta value to determine the expected return..

Objective To study if the Swedish venture capitalists consider business plans in their screening process, and in such case, what aspects they evaluate in order to develop a targeted template for Swedish entrepreneurs. A secondary objective is to describe what other factors Swedish venture capitalists evaluate as a part of their assessment. Methodology The method, which has been used in order to test the objective, has been carried out through extensive literature and article studies, interviews, and distribution of a short and comprehensive questionnaire to a multiplicity of venture capitalists throughout Sweden. Conclusion Generally, the findings of this thesis suggest that a business plan should include elements such as a summary of important elements, a thorough market analysis, financial information, exit strategy, and the risks associated with the project. The empirical material also reveals that venture capitalists also evaluate factors such as ownership influence, the entrepreneur?s industry knowledge, product knowledge and the personal chemistry in their evaluation process.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

Studien utforskar hur min livsvärld påverkades och förändrades då jag undersökte mina strategier för saxofonövning. Utgångspunkten för studien utgår från instuderingen som gjordes av Paul Bonneaus stycke Suiet pour saxophone alto et piano och de loggboksanteckningar som skrevs i samband med varje övningspass. Denna kvalitativa studie genomfördes utifrån ett livsvärldsperspektiv som kommer ur den fenomenologiska filosofin. Analysen av instuderingsprocessen kretsade kring mina reflektioner över hur jag ser på övning utifrån min livsvärld. I resultatet framkommer ett mönster som visar en övergång från negativt tänkande till mer positivt tänkande.

The web has evolved much through the years. From being a place where author and reader were clearly distinguished, it now invites everyone to take part in the development of both content and technology. Social services are central in what is called Web 2.0. Wikis, blogs and folksonomies are all examples of how the users and their communities are key to the development of services. Collaborative writing, tags and API:s are central.

The purpose of this study is to illustrate how three schools work with special education needs, what they consider is special education needs and what measures they put in for the student to achieve the goals. I will also study how the evaluation and the follow-up of the individualized education program work at the schools.The empirical material consists of all active programs in grades 7, 8 and 9, together with and interviews with special education teachers and the principal at each school. The results are compared with similar previous researches and analysed by two dominant perspectives of school difficulties.The result shows that it is mainly the critical perspective that dominates the individualized education program. The student is the carrier of the problem and is excluded in many cases from the other students in the class. These measures are different compensatory accommodations for the student in order to catch up with other students..

The aim of our study is to explore the thoughts and beliefs held by the professionals who work with the sentence youth service for young offenders, and how they feel about the same.How is the sentence youth service perceived from a professional perspective? How does the concurrence look like between the police, the social services and the prosecutor, when it comes to young offenders? What kind of difficulties/challenges do the professionals see in the possibility to effect the sentence youth service?The study is based on a qualitative method. The data consists of seven semi-structured interviews with two police officers, four social workers and one prosecutor.The results of our study indicate that youth service is a good sentence for young first-time offenders; the study also indicates that concurrence between the different professions is a success factor; furthermore the study revealed that it was very difficult finding adequate working places..

This is a study of how four teachers work with pupils? early literacy learning. Interviews were conducted with two teachers who chose to use a specific method, Writing to Read (WTR), for teaching pupils to read, and with two teachers who had not chosen a specific method. The aim of the study was to compare how the teachers worked, their motives for their choice of method, and the ideas the teachers have about early literacy learning. To see whether the teachers? choice of method was related to the individualization of the teaching and their views of pupils? learning in interaction, Vygotsky?s theories about children?s learning have been used.

The purpose with this review is to investigate evidence-based practice (EBP), and which arguments are used to justify EBP. The year of 2006 Bergmark and Lundström published an article regarding the problems concerning EBP. They are discussing that several different definitions of EBP are existing, which they mean can lead to difficulties using the EBP-methods in real life. In this study six articles, from the years 2007-2011, have been analyzed using Mertons structure-functional theory and Lipskys theory of street-level bureaucracy. Different definitions of EBP are discussed in the articles and there seem to be a need to clarify the concept.

This study aims to examine preschool teachers' thoughts about the child libraries functions. The purpose is to highlight preschool children's early read and writing skills, before they even can read and write, which is a theory called emergent literacy.This is made by conducting five qualitative interviews, with the intention to investigate how the preschool teachers think about the cooperation and the function of the child library, partly for their own work with the children and partly for their organization. By using a tablechart which shows each preschool teachers mostly common thoughts in the interview and by using a model based upon Harrysson and Joelsson (2006) model, which shows the functions of the public library in the society. The results of the study are presented in the four categories of the model which are; to borrow, to learn, to ask and to find, to reside. These are functions that the preschool teachers see with the library, for their work with the childrens' early literacy.

Ulf Lundell is one of the most famous songwriters and authors in Sweden. He has written fifteen works of fiction and they?ve all same theme ? a lonely man trying to look into his own past life. They are all built on a character, writing from an I-perspective, having a bit of Lundells own biography in there?s personality. The aim of his thesis is to find out how Ulf Lundell presents him self in his fictive characters, and will trace the authors development from a psychological point of view.

Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.

LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.

The purpose of this report is to investigate teachers views of whether pupils with Asperger Syndrome, autistic symptoms or ADHD shall go in ordinary classes or special groups. The study tells you about what difficulties these pupils often have, what adjustments they need in their schoolsituation and the positive and negative effects of joining a special group.A teacher for special needs, two teachers in special groups and two teachers in ordinary classes have been intervjued and earlier made researches have been studied.The conclusions of this study are that the decision of whether a pupil shall go in a normal class or a special group must be made individually. Most pupils who are capable to profit from the training in a normal class and pass their examination, shall go in a normal class. The greater part of the recommended adjustments are possible to do in a normal class. But it requires more resourses and teachers with better knowledges about theese handicaps..
