The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Denna rapport ger en bild av vilka olika saker byggherrar i Sverigeanvänder sig av idag för att öka den sociala hållbarheten. De projektsom studerats är Bygga om Dialogen i Malmö, Älvstaden i Göteborg,Vivalla i Örebro och föreningen Byggemenskap.Genom att intervjua en person från varje område studeras likheteroch skillnader i hur man arbetat med den sociala hållbarheten vidbyggnation. I Malmö och Örebro studeras arbetet med att öka densociala hållbarheten vid renoveringsobjekt, hur får de hela områdensom länge haft ett dåligt rykte att bli socialt hållbara där stort fokusligger på att anställa långtidsarbetslösa.I Göteborg och i föreningen Byggemenskap fokuserar man på attföra in den sociala hållbarheten vid nybyggnation och hur vi kan byggahyresrätter som har en lägre hyra än nybyggda lägenheter i dagslägethar..

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

Apple has since their launch of the Iphone series created a billion dollar business with the market place Appstore. Third-party apps have disrupted the mobile industry, attracted a high number of developers and set the standard for the industry. Despite success, this market has yet not been the topic of any academic study, a fact that makes this thesis important. Under the assumption that apps can be regarded as a service, traditional service marketing theories have been applied with the research goal to map existing business models, evaluate revenue potential and understand best practices of marketing techniques. A series of qualitative interviews with representatives from the difference business models, backed by secondary data describing the domain shows how the Appstore has evolved over time and which marketing practices that appear successful.

With increasing wine consumption and a growing assortment at available to Swedish consumers, there is an interest in understanding the decision making process of Swedish wine consumers. In this thesis the expert phenomenon is studied with respect to wine through wine critic reliability: grading objectivity, understanding the process of wine criticism and possible critic influence on consumer behavior. Two studies were performed; a qualitative in-depth session of interviews with industry connoisseurs and a quantitative analysis of 589 online wine reviews. Our results indicate that wine reviews are highly subjective and defy prediction through analysis of external variables. Critics are likely to judge differently based on what information they have at hand, suggesting that expectations affect grading.

Scania?s discount rate - the return requirement of investments - refers to Scania?s WACC or weighted average cost of capital. The capital markets return requirement on equity and the credit market interest cost of borrowing is weighted to become the single discount rate, the WACC. The purpose of this study is to investigate which asset pricing model of APT and CAPM Scania should use in their WACC calculations. The company now uses a group WACC of 11 percent which is used in all company levels.

Syfte Studiens syfte är att utvärdera internprissystemet på Blekingesjukhuset i Karlskrona. Metod Uppsatsen är en fallstudie av internprissystemet på Blekingesjukhuset i Karlskrona. För att tillföra en viss bredd till utvärderingen utgörs vårt empiriska material av intervjuer med såväl verksamhetschefer, planeringsstrateg, controllers samt sjukhusets ekonomidirektör. Med avsikt att underlätta presentationen av studiens resultat och utvärderingen, som sådan, har vi utformat en utvärderingsmall baserad på den information som samlats in under våra intervjuer. Slutsatser Studien pekar på att sjukhuset använder internprissystemet i syfte att skapa kostnadsmedvetenhet bland de anställda, för att på så sätt förhindra överkonsumtion av tjänster som utförs internt.

Denna studie jämför hur Capital Asset Pricing Model (CAPM) och Fama-French trefaktorsmodell förklarar och förutspår avkastning på en global aktiemarknad. CAPM utgår ifrån att investerarna förväntar sig en riskfri ränta adderat marknadspremien multiplicerat med företagens exponering mot marknaden. Fama-Frenchs är en utvidgning av CAPM modellen, där företagens storlek och book-to-market-värde läggs till som förklarande variabler för avkastning. Genom regressionsmodeller och prediktioner för portföljer indelade i storlek och book-to-market jämförs modellerna. Fama-French tycks vara genomgående bättre på att förklara och förutspå avkastning under perioden 1990m07-2013m02 för samtliga portföljer, förutom portföljen för stora företag med medelhögt book-to-market värde.

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

Titel: Internprissättning ? skattekonsekvenser av internprissättning i multinationella koncernerProblem: Beskattningsåret 2007 infördes en regel med krav på att företag i intressegemenskap måste dokumentera grunden för sin internprissättning. Organisation for Economic Co-Operation and Develoment har givit ut en samling rekommendationer kring detta. Denna samling behandlar dels förkommande dokumentationskrav men även modeller för hur internprissättning skall upprättas. Ovanstående har utmynnat i följande frågor.

This thesis examines the emissions costs of Swedish aviation and their degree of internalisation under current economic instruments. The results show that the degree of internalisation spans from practically zero for a long-haul flight to 6 per cent for a typical domestic flight, where the climate cost, including high-altitude impact, makes up the main part of the cost. To inform evaluation of the consequences of this underinternalisation, or attempts to correct for it using price instruments, the price and income elasticities of international leisure air travel from Sweden are estimated using household expenditure data and two different price measures. The resulting elasticities are very high ? 2.03 or 2.04 for the income elasticity and -2.53 or -1.88 for the price elasticity ? and should be interpreted cautiously due to data limitations, especially for the price elasticities.

Syftet med denna uppsats var inledningsvis att redogöra för de allmängiltiga internprissättningsmetoderna, motiven bakom dessa och undersöka vilka som används av svenska multinationella koncerner. Avsikten var vidare att beskriva de kommande dokumentationskraven avseende internprissättning samt dess förväntade inverkan på efterlevnaden av armlängdsprincipen och företagens strategi för koncernintern handel. Resultatet visade att interhandel främst skedde med varor, men i viss mån även tjänster, varumärken och patent. Merparten av de tillfrågade använde sig företrädesvis av metoden rådande marknadsprissättning, dock förkom också uppskattat marknadspris, självkostnad samt självkostnad plus vinstpålägg. Hälften av de tillfrågade koncernerna var medvetna om den föreslagna förändringen av dokumentationskraven vid intern handel.
