The purpose of the study is to examine how teachers and students believe that graphing calculators affect the teaching of high school mathematics courses. By becoming aware of this, teachers and teacher students have the opportunity to reflect on the use of graphing calculators in their teaching. The empirical base consists of interviews with teachers and a survey among students at two high schools in southern Sweden. The results show that teachers especially consider the graphing calculator as a tool, much like paper and pencil. They use it if and when it is deemed able to contribute in a significant way in their teaching, either to save time and/or to help deepen the understanding of various mathematical concepts and methods.

This study departs from the observation that since the late 1980´s educational programmes for curators have been established and since then expanded greatly. The programmes are part of a process of institutionalization and professionalization of the role of the curator within the international contemporary art field where the role as such has gained much power. Even though many statements have been made about this relatively new phenomenon of curatorial studies, there is a lack of sufficient research. The intention of this study is therefore to examine the educational programmes as such. The selection of 15 programmes has been made with the purpose to include early as well as newly established and to cover a wide geographic area.

Abstract The purpose of the study is to examine how children perceive the relation between play and sex and analyse it from a gender perspective. This by answering the questions: "Is the children?s choice of place, materials and company in play dependent on gender?" and "Is there a significant difference between the sexes and/or ages?" The study was done through twelve focusgroup interviews with three children in each group except two groups of two children in each. Eight boys and nine girls of six years old and nine boys and eight girls of nine years old were interviewed. Boys and girls were interviewed in separate groups and the questions were open ended and followed up.

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

There is a general conception among those who are involved in the school-sector that there is a relation between resources and results. Better qualified teachers, smaller classes and schools with more finacial funding are regarded as better learning and development conditions for pupils (Gustafsson 2008). In spite of these widespread understanding, educational and economic research studies at the beginning of the 20th century had reached the verdict that resources have no bearing on educational results (Gustafsson 2008). The Swedish board of education (Skolverket) have published several reports, studies and surveys regarding the relation between resources and student outcomes.The purpose of this paper is to analyze the message of six publications from the Swedish board of education around the relationship between resources and student outcomes on the basis of the decentralization of the Swedish school in the 1990´s. The central question at issue is whether the Swedish board of education has been consistent in their message about the relationship between resources and results in the six publications between 1994-2009? I have also attempted to answer the resulting questions of my conclusion.This study is based on a qualitative text analysis.

The reason I am writing this essay is due to my curiosity on how children are interested in and how their understanding in geometry is at preschool years.My interest lies in children and arithmetic and especially geometry, which is something I belive that children deal with a great deal in their everyday routines, both in school and at home.What do children do when they work with geometry, and are they aware of what they do? To figure this out, I have taken my findings from three different interviews that I have done atmy preschool with a group of children that have been preselected.I am also curious about whether there is a difference in different types of schools. In this essay I have compared the preschool I work with a Montessori school and a third type of schoolwhere the children spends most of their day´s outdoors called ?Ur och Skur?In my results I can not see any major differences in these three preschools work with mathematics. The childrens knowledge is at a similar level and the work with geometry hasbeen implemented in a similar way..

Denna magisteruppsats handlar om lärande och hur det påverkar individer, projekt och organisationer. EU: s nya satsning på 450 millioner euro, för 2005, visar att fenomenet lärande är ett, i allra högsta grad, aktuellt ämne. Det förs en diskussion om varför lärandet finns och på vilket sätt det inverkar på projektprocessen. Det redogörs även för olika sätt att se på projekt och hur det står gentemot process samt hur stress, tid, kostnad och lärandet står i perspektiv till detta. I undersökningen förs även en diskussion om, på vilket sätt informationsteknologiska projektverktyg kan stödja lärandet..

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

Vi började vårt projekt med grunderna till verktyg för att utveckla spel i 2d. Dessa ämnade vi färdigställa under projektet och med dem utveckla en speldemo. Eftersom vi hade gemensamma visioner om spelutveckling så bestämde vi oss för att samarbeta, och fokusera på våra respektive områden. Med att utveckla egna verktyg ville vi få en större förståelse för de grundläggande mekanismerna av en spelmotor och möjligheten att påverka dessa efter våra specifika behov. Det var också för att hålla koden fri från licensierade komponenter för att i framtiden kunna underlätta distribution..

Organisationer har under den senaste tiden gjort stora ansträngningar för att integrera informationssystem med målsättningen att uppnå en ökad effektivitet men utan större framgång. Vi vill identifiera rådande kritiska framgångsfaktorer och deras påverkan på portallösningar. Utifrån syftet identifierade vi två centrala områden för litteraturstudien, närmare bestämt ?Enterprise Application Integration? (EAI) och kritiska framgångsfaktorer (CSF). Insamling av empirisk data gjordes i form av intervjuer på ett kvalitativt tillvägagångssätt.

Arbetet handlar om hur sex barn i svårigheter med matematik uppfattar sig själva som matematiker, hur de finner att andra uppfattar dem som matematiker och vad det beror på samt hur den matematiska självuppfattningen är hos dessa elever. I studien har jag arbetat kvalitativt med en fenomenografisk ansats, där datainsamlingen skett genom intervjuer, i en år fem klass på en skola i sydöstra delen av Sverige. Resultatet visar b. la. elevernas matematiska attityd, känslor och tillfredställelse.

In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. The Hawking mass is quasi-local and defined by the spin coefficents of Newman and Penrose, so first we give a discussion about quasi-local quantities and then a short description of the Newman-Penrose formalism..

The intention of this final thesis is to examine how to create a schoolyard that inspires children at the age of 6 ? 12 years to play and give them possibility to develop. To get a lot of knowledge in this subject, I have combined studies of literature with practical studies at Hosjöskolan in Falun. During my practical studies I have done interviews, walks in the area with the children and visited other schoolyards. I have based a design proposal for the schoolyard of Hosjöskolan on these studies.

Denna uppsats behandlar vilka negativa konsekvenser som kan uppstå vid outsourcing av digitala tjänster i en service-oriented architecture (SOA) miljö. Uppsatsen behandlar endast negativa konsekvenser i relation till kontrollen över den information som existerar i de tjänster och i de affärsprocesser som utgörs av tjänster som outsourcas. Syftet och resultatet av uppsatsen är en punktlista som presenterar dessa konsekvenser. Empiriskt material har samlats in genom användningen av ett teoretiskt ramverk som varit ämnat att ta reda på vad och hur tjänster är och hur dessa kan kopplas mot outsourcing. Den slutgiltiga punktlistan pekar på flera punkter som kan gå fel om organisationer väljer att outsourca sina tjänster..
