Bakgrund: Aktieindex används världen över som placeringsalternativ, jämförelsemått inom portföljförvaltning och som underlag för portföljoptimering. Forskare har under senare tid ifrågasatt index viktade efter börsvärdet och alternativa viktningsmetoder för index har framtagits som substitut till det kapitalviktade indexet och prestationsjämförelser har gjorts. Studier har främst gjorts i USA och denna studie ämnar göra en liknande undersökning på den svenska marknaden. Syfte: Syftet med vår studie är att undersöka alternativa viktningsmetoder på det svenska aktieindexet OMXS30 och dess historiska prestation under åren 1995-2011 i förhållande till det traditionellt kapitalviktade OMXS30. Syftet är vidare att analysera de alternativt viktade indexen som grund för portföljoptimering enligt Single-Index Model. Genomförande: Fem alternativt viktade index konstrueras i studien där viktningen grundas på fundamentala värden, Sharpekvoter, standardavvikelse, likaviktning och handelsvolym och jämförs prestationsmässigt mot OMXS30. Indexen används sedan vid portföljoptimering enligt SIM där aktiers och portföljers karakteristika analyseras.

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.

Integration is a phenomena that occurs in all societies that experience any form of immigration. This process is dependent on how we analyze, both the groups of immigrants, and how we analyze the society in which they becoming integrated.Intersectionality is one method of analyzing this framework. By applying the categories: gender, class and race on the integration process, we get a more complex picture of the subject. Therefore we also become more able to adjust the actions and arrangement around the different questions of inte-gration.In this essay I try to explain what the intersectionality is, how it is used and how it can apply in integration as a specific subject. I also apply the intersectionality model on different policy documents from Malmö, Vellinge and Landskrona to find out if they show any awareness of this model both explicitly and implicitly..

This essay examines upper secondary school pupils as well as the Swedish National Agency for Educations views on the education in subject of religion. How they describe its purpose, what content the topic should address, how the education should be implemented and what influence the pupils should have over their own studies. This to examine how the views of pupils and the Swedish National Agency of Education correlate and to analyze how it possibly can affect the pupil?s motivation. The survey is conducted by semi-forging tured interviews and text analysis in order to ascertain the pupils and the Swedish National Agency of Educations opinions on the issues.

Swedish students' knowledge of mathematics has deteriorated in recent years. Teaching of mathematics is therefore starting point in an ongoing discussion among researchers, school leaders, politicians, teachers and others, who all thinks they know best about how teaching should be designed to the greatest extent possible to raise students' proficiency levels in the subject. Teachers' practices have long been the focus of discussions and views on these differ. The purpose of this paper is therefore to study students 'conceptions of mathematics and mathematics teaching, with teachers' methods and tools of focus, in relation to previous research on the subject. The method used was a survey of students in secondary school and a textual analysis of previous studies on the subject.As revealed by the survey was that the textbook has a big advantage in mathematics education in Sweden today.Many students are not accustomed to working in a different way and thereforedoes not know either what the alternative approach entails.

AbstractBachelor essay in Pedagogy by Johan Lidén &Kristian Sagfors, 2011."Genus i gymnasieskolan: En oengagerande fråga?".Supervisor: Zeki YalcinGender and gender equality in our school system has throughout the years become a well researched subject, however most of that research has focused on the lower levels of compulsory school. The upper secondary school has not gotten the same attention.We have chosen to explore how social science teachers in upper secondary school treat the subject of gender and gender equality, what strategies they apply in the classroom and how their pupils respond to the subject.We wanted to get access to their classrooms so we could do an ethnographical study to find the answers to how their lessons were planned and executed, if different teachers made different didactic choices depending on the orientation of the class. As our work progressed we ran in to an interesting problem which ultimately made us rethink the purpose of this paper.In our pursuit of respondents we contacted many schools by e-mail and later visited the schools to find participants. This proved difficult as we were met with a wall of silence and lack of interest.

This literature study assembles current knowledge about CODD (Contagious Ovine Digital Dermatitis). The aetiology of this disease is not completely known and to obtain a manageable overview, this study aims to summarize the knowledge from published studies and shed light on the subject. Search for literature on the subject has been made in the Web of Knowledge, PubMed and Google Scholar, and has been compiled in this paper. Footrot and ovine interdigital dermatitis are differential diagnosis of CODD and they possibly have a common role in the emergence of CODD. Several studies have drawn parallels to bovine digital dermatitis.

Löpekonomi är en viktig faktor för prestation hos löpare. En person med en god löpekonomi kan springa en given sträcka snabbare eller springa längre vid en konstant hastighet. När en sena sträcks ut lagras energi i vävnaden som sedan utnyttjas vid den efterföljande koncentriska kontraktionen i löpsteget. Detta fenomen kallas stretch-shortening cykeln (SSC). Det finns en stark korrelation mellan att på ett effektivt sätt använda sig av SSC och ha en god löpekonomi.

The purpose of this essay is to analyze and understand the effects that a recession can have on a company?s marketing department. In times of a recession most companies have less means to promote their products to their target market and to build their brand. This means that cutting the marketing budget will show some effects on today?s way of marketing.

The 3:12-provisions are part of a legal system specified for owners of close corporations (companies owned and managed by a small group of businesspeople), for taxation of capi-tal gains and dividend. The reason for special rules for the taxation of these owners is to prevent them from transforming their income, to only be subject of the lower taxation of capital gains, instead of income of service. Since the rules were put in force, they have been subject to several changes. The most recent changes took effect on the 1 January 2006. They involve a higher importance for the rule of salary-based taxation.

The purpose of this Bachelor's thesis is to study the reasoning behind classification, cataloging and shelf arrangement of nonfiction graphic novels in public libraries. The aim was to examine which aspects of accessibility influence in which collection nonfiction graphic novels are placed.With qualitative semi-structured interviews we learned how six librarians motivated their choices concerning nonfiction graphic novels. We also interviewed a cataloger from Bibliotekstjänst to examine how nonfiction graphic novels are classified. In our analysis we compared our results to theories and practices concerning alternative shelf arrangements in libraries and legitimization of graphic novels. We found three types of shelf arrangements for nonfiction graphic novels: graphic novel shelf, nonfiction classification code and a mix of the two.

Idag går utvecklingen mot alltmer distribuerade IT-system där en grupp datorer kommunicerar med varandra. Detta gäller för sökmotorer, beräkningsintensiva miljöer och även för den svenska försvarsmaktens ledningssystem.För att systemen ska kunna kommunicera så flexibelt som möjligt vill man ofta att kommunikationen ska ske enligt standardiserade protokoll vilka är oberoende av datorplattform, programmeringsspråk och transportprotokoll. Ett koncept som kan användas för denna sorts kommunikation är Web Services vilket är ett koncept där meddelanden skickas XML-formaterade över valfritt kommunikationsprotokoll.För att möjliggöra utbyte av känsligt data som inte får nås av obehöriga måste kommunikationen stöttas av ett flertal viktiga säkerhetsfunktioner. En av dessa funktioner är användarautentisering vilket innebär att användarens identitet kan verifieras.För att möjliggöra användarautentisering kan digitala certifikat och asymmetriska kryptooperationer användas, denna typ av operationer är prestandakrävande varför ?Single Sign On? eftersträvas.

The aim of the "Green forest management plans" is to help forest owners to reach the environmental goal of the forestry act. But are they able to do that? Is it possible to plan preservation of species on single estates? How do single-estate-plans differ from a landscape analysis and how can the landscape approach be used in operative planning? This work was initiated to give an answer to these questions. This study was made in a landscape of 4200 ha in Östergötland county, south-eastern Sweden. A lanscape analysis was made and then compared to the Green forest management plans in the same area. The nature conservation areas (areas that were set aside to be managed with environmenatl goals) differed quite a lot between the two alternatives.
