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.

Natten mellan den 19 och 20 mars 2003 inledde koalitionstrupper Operation Iraqi Freedom. Detta var slutet på det som kom att gå till historien som Irakkrisen.30 år tidigare formulerade Graham Allison en teori, i form av tre modeller, för att förklara utrikespolitiskt agerande utifrån Kubakrisen. Vi har prövat huruvida Allisons teori fortfarande kan förklara utrikespolitiskt agerande genom att pröva den på Irakkrisen. Detta har operationaliserats genom en systematisk genomgång av tillgängligt material som behandlar uppsatsämnet.Efter att ha betraktat Irakkrisen utifrån Allisons tre olika modeller kan vi konstatera att teorin fortfarande är bärkraftig. Dock behövs viss komplettering till den 30 år gamla teorin ? i form av en inrikespolitisk analys, bredare organisationsanalys samt en djupare value- och beliefsystem-analys ? för att kunna åstadkomma en fylligare undersökning som förenar Allisons modeller med dagens verklighet..

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Studien har handlat om att ta fram riktlinjer för hur extrahering, transformering och inladdning (ETL) av kreditbedömningsinformation bör göras när det kommer till att införa ett Data Warehouse (DW). Ett kvalitativt angreppssätt har använts med både en fallstudie och en intervjustudie, där fallstudien genomfördes med Asitis AB som är en systemleverantör förfinans- och reskontrafinansiering (factoring) för att undersöka potentiella affärsmöjligheter med ett DW med kreditbedömningsinformation. Intervjustudien användes för att samla in värdefull information från individer inom alla berörda problemområden, och användes sedan i fallstudien. Resultatet var både framgångsfaktorer och fallgropar för ETL-processen med kreditbedömningsinformation som kan fungera som stöd för organisationer med detta behov. Det har visat sig att ETL-processen för kreditbedömningsinformation utgör ett område med stor potential för affärsmöjligheter, där det krävs hög kompetens, domänkunskap, proaktivitet och juridisk kunskap vid genomförande av ETL-processen..

The purpose of this essay is to present, from a theoretical framwork about regional democracy, possible methods to handle the regional democratic problems in Östergötland in Sweden and to investigate the opinion of the political parties regarding this issue. Both the national and the local/regional level are investigated. The contents of the essay is based on literature studies and interviews of politicians in Östergötland. Regional democratic problems that is discussed are the political responsibility and the power distribution between the political actors on the regional level. A solution of the problem could be to organize the regional society structure in accordance with one of the following organization models"Statligt regionalt ansvar","Kommuner i samverkan"or"Regionalt folkstyre".

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: Can nutritional support contribute to the healing of pressure ulcers in elderly patients?Author: Anton Kinnander, Sandra SmidelikSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 12-04-11Background The number of elderly patients with co-morbidity is increasing in the western world. It is therefore reasonable to predict increasing incidence and prevalence of pressure ulcers. One study, published 2009, found that as many as 59 % of geriatric patients within the Swedish health care system had developed pressure ulcers. Symptoms vary from mild erythema to severe deep tissue damage and development of pressure varies from hours to weeks.

The objective of this literature study was to describe how the school nurse can adopt the salutogenic perspective in her health promoting work. The articles were examined in order to identify what was written about the school nurse?s work from the salutogenic perspective. In parallel, Eriksson?s, Orem?s, and Newman?s nursing theories were examined from the same perspective.

This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.

The purpose of this essay is to examine whether the descriptions of Stalin's terror in history textbooks for high school changed from the 1950s until the 2010s. Since previous research shows that textbook content is influenced from different directions and that it dominates in teaching, therefore I want to find out what similarities and differences that exist in the textbooks. The survey is based on a qualitative approach because I want to have a profound picture of the descriptions of Stalin's terror. The results of the survey show that the number of casualties and the descriptions on the famine has changed over time. Furthermore, textbooks also found it difficult to distinguish between terror, politics and ideology.

AbstractTheoryWhich education model has the ultimate learning potential? According to Olga Dysthe a varied education predominated by a dialogical nature is the best way of teaching.PurposeMy main purpose in this essay has been to investigate three different ways of education models and decide, on the basis of Dysthes? model, whether they can be classified as a monological or a dialogical model.I have also investigated if the thesis of Dysthes, ?The teachers view of knowledge determines the choice of teaching method?, is anchored in the reality.Furthermore, I have surveyed how the teachers educate concerning democracy. For example, on the basis of certain rules, are all sudents able to make the selves heard in a classroom that is characterized as dialogical? In such a classroom the teacher works whith activities to involve everyone and according to Dysthe, democracy is an attitude rather than a political system. Democracy is necessary in a classroom that is classified as dialogical.ResultThe essay is exclusively qualitative and builds upon interviews with three teachers on different upper secondary social schools witin the Gothenburg area.My results indicate that the teathers way of educating totaly differs from each others and that the thesis of Dysthe can be applied on only two out of three cases.

ENGLISH SUMMARYTitle:The ambiguous scorePresenting romantic piano pieces from simplified scoresIn this essay, I have investigated if different types of simplified scores ? scores whose musical structure are clearer compared to the original ? can stimulate a more artistic interpretation as well as a more linear understanding of the piece. My analysis also investigates what kind of impact these kinds of scores have on memorization.The music is derived from the romantic piano repertoire and the subjects are six university-level music students. Half of them were placed in a reference group, and only received the original scores, while the others also received the altered versions. I used both reduced scores where notes were removed in order to emphasize the linear structure and scores where the pitch notation was the same as in the original , but the notes were grouped differently.The result indicates that those having access to multiple versions had a positive impact on the musical interpretation.

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

The purpose of this essay is to investigate how people can return from a marginalized position and become a part of society. Also how a model for returning from a marginalized position should be formed. The intention is to make a contribution to those in society that are helping people to return from marginalized positions. The survey is based on 5 thematic qualitative interviews on individuals that have returned from homelessness, criminality, drug abuse and prostitution. The main results of the investigation are that those who took part in it started their role exit with a turning point.

Since 1996 the Swedish households have ten folded their volume of loans for own homes that is attached to a floating interest rate. Also in 1996 the Swedish electric market was deregulated. These two facts have increased the volatility in the household expenses for these two commodities. This thesis studies the risk for homeowners attached to the exposure against the electric and the credit market. The risk model used is Cost-at-Risk which is usually used by public authorities for analysing the risk involved with national debt.

The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
