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.

The purpose of this essay is to examine what literary heritage teachers communicate in the school subject Swedish at upper secondary school. The overall research question for this work is: Which authors and/or works are mentioned by the teachers in the school subject Swedish at upper secondary school? How well do these authors and/or works answer towards a multicultural perspective? Which factors affect teachers´ selections of texts? Based on this purpose and these research questions, the aim is to answer the didactic question of what.To accomplish the purpose of the study a quantitative method has been used. The survey was conducted in two medium-sized cities in central Sweden, and was answered by 17 teachers. The study shows that the teachers ascribe the Western and Swedish literature great importance.

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..

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..

The purpose of this project is to survey the presence of folk expressions, i.e. proverbs, proverbial expressions, wellerisms and familiar expressions, in some of the realistic children?s books by Astrid Lindgren. The purpose also includes the study of the contextual and pragmatic functions of the expressions as well as how the expressions are integrated into the text by the change of the formulaic standard structure. The contextual and pragmatic function concern when, how and why the expressions are used and who the users of the expressions are.

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..

Syftet med denna studie var att undersöka elevers användning av lösningsstrategier i subtraktion samt lärares och läromedlens framställning av dessa, för att kunna komma fram till hur en framgångsrik undervisning i subtraktion, med fokus på lösningsstrategier, kan se ut. Undersökningen genomfördes i tre klasser i åk 3. Metoder i studien var elevenkät, intervju med lärare och läromedelsgranskning. Data bearbetades med hjälp av en egenkonstruerad begreppsmodell utifrån olika lösningsstrategier. Resultatet visar på en större variation av lösningsstrategier i undervisningen än i elevernas uträkningar.

The purpose of the study is to investigate educators? attitudes and didactic positions on popular culture as a form and a means of children?s learning in preschool. The questions posed in the study are:? How do the educators define popular culture, which examples of popular culture do the educators give?? How do the educators describe the spoken and unspoken rules and positions regarding popular culture in preschool practice?? What are the risks and benefits when including popular culture in preschool, according to the educators?In this qualitative study four educators from different preschools have been interviewed. The preschools take as a starting point different educational philosofies.

Syftet med denna studie är att få ökad insikt om hur förskolelärare uppfattar sitt eget arbete med att främja barns begreppsutveckling inom området volym. Syftet med studien är även att få ökad kunskap om vilka aspekter som påverkar den dagliga verksamheten inom området volym i förskoleklassen. Denna undersökning är baserad på intervjuer med sex förskolelärare, materialet har bearbetats och kategoriserats under fem stycken huvudrubriker som belyser olika aspekter av hur förskolelärarna uppfattar att de arbetar med området volym i förskoleklassen. Vi har valt att belysa denna undersökning ur ett sociokulturellt perspektiv. I vår analys har vi kommit fram till att det finns många olika aspekter som påverkar utformandet av verksamheten i förskoleklassen.

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.

Elektroniska böcker är ett relativt nytt koncept som inte riktigt gjort några stora landvinningar, trots att ny teknik kommit och framsteg görs. Syftet med uppsatsen är att se vilka brister som finns i utlåningssystem för e-böckerna. Med hjälp av en kvalitativ undersökningsmetod tar vi en närmare titt på Malmö och Lunds stadsbiblioteks hemsidor. Intervjuer av bibliotekspersonal och användbarhetstest samt en teorigenomgång är basen för vår undersökning. Med hjälp av detta ville vi se vilka brister som fanns vid utlåning, ur ett användbarhetsperspektiv, och dra våra slutsatser utifrån de resultat vi fått.

This study is about assessment, in particular formative assessment also called assessment for learning. The purpose of this study is to investigate Swedish and South African primary school teachers? views and ideas about this didactic tool. The motives for this investigation are based on the fact that correct used formative assessment supports pupils? learning process and the fact that there are few researches made about this subject in Sweden.

The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.
