Den amerikanska subprimekrisen i ett historisktteoretiskt perspektiv : En undersökning om hur USA:s subprimekris överensstämmer med Kindlebergerstolkning av Minskys modell
This paper aims to analyze the effect of the American Subprime crisis of 2007 through the perspective ofHaynes Minsky?s model according to Charles Kindleberger. The investigation revolves how the anatomyof a financial crisis develops and how it is applicable to the Subprime crisis. More specific conclusionsare derived from applying Minsky?s model to the three largest American indices; Dow Jones industrialaverage, S&P500 and NASDAQ.To deepen the analysis the Case-Shiller home price indices acts as a second parameter tocompliment Minsky?s perspective with Robert J.
Det är inte bara verkligheten som räknas : Hur uppfattas miljöer i 2D och 3D?
Being able to take a decision on an area you've never seen is a difficult task. It is also complicated to introduce an environment in the best way to benefit its purpose. This study focuses on the differences people notice between 2D and 3D models. To make it more concrete, the study has been linked to a case study called Ha?lsans va?g 255.

Hus på väg : En kostnadsstudie över flyttning av tre enfamiljshus
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.
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
Black-Scholes : En prissättningsmodell för optioner
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.
En kritisk diskursanalys av svenska dags- och kvällstidningars framställande av ADHD
The aim of this study is to examine how ADHD is discussed in the Swedish mass media. We have examined 21 articles from Aftonbladet, Expressen, Dagens Nyheter, Göteborgs-Posten and Svenska Dagbladet. All articles are reviewed from the newspapers online edition.Theories used are Erving Goffman?s theory of Stigma and Michael Foucault´s theory of categorization as well as Göran Palm's, Renée Skogersson's and Anders R. Olsson's theories about mass media.
Essence of Decision: Explaining the War on Iraq
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..
Skillnader i energiåtgång och muskelaktivering vid gång utan stavar och med olika typer av stavar
Background: Patients who deliberate self harm often feel disappointed with the health care. The consequence of this may be that the patient avoid to seek help after self harming. Nurses' often experience these patients to be difficult and hard to deal with. Both patients' and nurses' thoughts about the situation may affect the situation in a negative way. A good relationship between the caregiver and patient is important.
Bibliotekariebilder i dagens platsannonser. En diskursanalys.
The aim of this Masters thesis is to examine the librarian discourses that can be identified in the job advertisements of today, to examine how the discourses differ and also how these discourses might influence the librarian profession and its status. The method of investigation is a qualitative analysis of printed sources, using Ernesto Laclaus and Chantal Mouffes discourse theory as well as the theory of professions as a theoretical base. The thesis shows that two discourses can be identified in job advertisements for 2004, one public librarian discourse and one scientific librarian discourse. The major difference between the two discourses are work tasks where the public librarian discourse very often contains areas of responsibility and development work, whereas the scientific librarian discourse often contains administrative work tasks. Other differences include a great demand for driving licences and an interest in children and youth in the public librarian discourse, something which is not asked for at all in the scientific librarian discourse where there is a great demand for knowledge of languages instead.
Utvärdering av laddningskoncept för lastbilsbatterier
When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.
Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system
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.
Klassificering och värdering av finansiella instrument : Ett tillförlitlighetsperspektiv
During the financial crisis voices were raised towards the regulatory framework IAS 39 recognition and measurement of financial instruments and pointed out that it was inadequate. The complexity of the framework contributed to the fact that it was difficult to apply. IASB accelerated the modeling of the new to be regulatory framework IFRS 9. In this study we will focus on the reliability of accounting information, which is an important aspect from the stakeholder?s point of view, for example, to be able to make the best decisions the accounting information should be proper.
