Purpose: During the last years Real Options have been established in many areas of the day-to-day business. Recent literature also tries to address Supply Chain problems with option theory, since an efficient Supply Chain increasingly gains in importance as a significant competitive advantage. This thesis tries to answer the question, if Real Options can mitigate the costs induced by the Bullwhip Effect as one of the major problems in Supply Chains. Methodology: The authors of the thesis used a deductive approach. Based on a theoretical model utilizing Real Option contracts and under the usage of a randomly created dataset the influence of the Bullwhip Effect on the company?s business and financial structure is examined and subsequently analyzed.

Syftet med detta arbete är att analysera hur Ringhals reaktor II kan ersättas med hållbar energiproduktion. Detta görs genom att analysera vilka produktionstekniker som är kommersiellt gångbara i Sverige. Sedan analyseras dessa utifrån dess geografiska och tekniska begränsningar i regionen Västra Götaland och Halland för att bestämma hur den nya energimixen kan utformas. Utifrån energimixen simuleras sedan energiproduktionen i elzon 3, SE3, under varje timme över ett år för att undersöka om den nya produktionen kan möta efterfrågan och huruvida elnätet kommer att belastas hårdare på grund av eventuell ökad transmission till/från andra delar av landet. Från energimixen beräknas även vad produktionskostnaden för elektriciteten blir för den alternativa produktionen. Resultatet visar att den föreslagna energimixen klarar av att ersätta energiproduktionen från Ringhals reaktor II med endast en marginell ökning i transmission till/från regionen.

Surveys show that consumers tend to avoid traditional marketing channels, leading the practitioners to use earned media channels through public relations (PR). This has also led to the use of covert PR. To understand the use of this communications method, the purpose of this thesis is to study campaigns, which have gained transmission in social media, by investigating how practitioners of three different campaigns motivate the choice to use covert PR.The study is based on a hermeneutic methodology and has an abductive approach. It is carried out by semi-structured elite interviews with six contributors of three different campaigns, using covert PR. The primary data consists of the empery of the interviews, while the secondary data consists of a theoretical framework of excellence in public relations, the PR practice and viral messages.The result of the study indicates the point of view that covert PR has given the campaigns a wider reach.

This study examines how the stock prices are affected when articles, which negatively describe the companies? incentive programs, are published. According to the efficient market hypothesis, only new information should have an effect on the stock price. Furthermore, this study aims to examine whether this reaction is dependent of the economic climate. During the period of September 2005 to September 2009, stock price data was collected from the NasdaqOMX stock exchange and 75 articles were gathered from leading Swedish newspapers.

The thesis is aiming to investigate what happens in the customer-service worker interaction when the service worker is wearing religious attributes. In order to operationalize this the Muslim head scarf, hijab, is chosen as stimuli. Reviewing previous research and theory in this field, it is clear that people have a preference for people that they perceive to be like themselves, this is referred to as homophily. Further on, the study investigates the ethnicity dimension of the service worker customer interaction. Theoretical areas of attractiveness and color are also investigated.

The purpose of this study is to examine the expiration day effect on a stocks volatility due to stock option expiration, which is every third Friday in the month on Stockholm stock exchange. Volatility is the standard deviation of a stock. It measures the uncertainty about a stocks future movement. When volatility increases, the chance or probability of a stock going up or down increases. It?s a common rumor among stock traders that stock volatility tends to increase nearby expiration day.

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

Syftet med studien var att undersöka huruvida utsattheten för ?sunk cost-effect? och förankringseffekten ökade vid intuitivt processande jämfört med analytiskt processande. Deltagarna i studien var 78 studedenter vid psykologiska institutionen vid Göteborgs Universitet. Datainsamlingen gjordes genom en pappersenkät. En 2 × 2 - vägs ANOVA avseende bias och process gjordes för både ?sunk cost effect? och förankringseffekten i en mellanindividdesign.

This quantitative study aims to investigate whether there is a difference in the effect of the policy rate on the price per square meter for condominiums between small and large cities in Sweden. The study encompasses a total of seven Swedish municipalities, of which three located in large cities and four in small cities. Data regarding housing sales and additional variables have been collected for all municipalities, and the price per square meter is the dependent variable in the regressions performed on the dataset, which constitutes the empirical basis of the study. The aim is further to contribute to an increased understanding of how the effect of the policy rate might differ between Swedish cities and why. The results of the study show significant differences in how the policy rate affects the price per square meter in a small city compared to a large city, with the effect being greater in the latter.

Antalet järnvägstunnlar i tätbebyggda områden kommer att öka de närmaste 20 åren. Därför finns behov av bra förutsägelser om vibrationer och ljud orsakade av tåg i fastigheter utmed de planerade tunnelsträckningarna. Förståelsen för hur tåginducerade vibrationer propagerar i bergmassan är i dagsläget begränsad. Eventuella för- och nackdelar med bergets och sprickors egenskaper kan då inte utnyttjas optimalt. Syftet med detta examensarbete är att studera hur lågfrekventa vågor propagerar genom (i) en godtyckligt orienterad spricka samt (ii) multipla parallella sprickor.

A zoonosis is a disease or infection that is naturally transmitted between vertebrate animals and humans. The majority of infectious diseases that affect humans are zoonoses. Environments where wild animals, domestic animals and humans live in close proximity with no or small boundaries in the ecological system favor the transmission of diseases between animals and humans. The above described situation is more common in low income countries, where humans and animals live in high density and zoonoses are generally more common. The study was conducted in Cambodia.

In recent years cognitive training in order to improve cognitive abilities have becomeincreasingly popular and a lot of research has been conducted within this field. The natural agingprocess has a negative effect on many of our cognitive abilities and this relationship also has a strongconnection with hearing loss. Elderly with hearing loss is therefore a group that could benefit fromcognitive training. Objective: The purpose of this study was to investigate different types of cognitivetraining directed towards working memory in older adults and to examine the results observedregarding efficacy of this type of training and its transfer effect. Method: A literature reviewconsisting of 17 scientific articles published between 2005-2014.

This essay aims to examine how the synthetic non-human subjects, EDI and Legion, are constituted in terms of their bodies, gender, desire and emotion, in the gaming series Mass Effect. In a close-gaming method I also want to explore in which way the gamer can effect or even change the expressions of the body, gen­der, desire, and emotion made by the synthetic non-human subjects. In order to do this I use Judith Butlers and Sara Ahmeds queer theory, and Donna Haraways cyborg feminism. I concluded that EDI em­braces her embodiments and is given a highly sexualized female body, being more of a woman than a machine. While Legion is rather embracing disembodiment and is given a non sexualized, androgynous male body, be­ing more of a machine than a man.

This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets, treatment in which, nutrient solution was based on Vortex-treated water was compared with an control using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and internodal length were significantly different in tomato plants grown in Vortex-processed water compared with the untreated control.

Skolverket menar att populärkultur, däribland dataspel, är användbara verktyg för att nå elevernas livsvärldar i religionskunskapsundervisningen.Den här uppsatsen undersöker den religionsdidaktiska potentialen hos Mass Effect-spelen i gymnasieskolan utifrån följande frågeställningar:Får rätt och fel handling något utrymme i Mass Effect? På vilket sätt? Vad är rätt och fel i spelkontexten?Kan Mass Effect fungera som stödstruktur för att arbeta med stoff och förmågor som är en del av religionskunskapens etikundervisning och i sådana fall på vilket sätt?Spelkontexten utforskas genom en analys av hur spelens Paragon/Renegade-system bedömer olika handlingar. Systemet jämförs med plikt-, konsekvens- och dygdetiska förhållningssätt; dessa är etiska modeller som tas upp av styrdokumenten. En av spelens beslutssituationer granskas också utifrån en beslutsmodell och styrdokumentens etiska modeller bidrar här med teoretisk och kursplanemässig förankring.Undersökningen visar att flera av de områden som ska ingå i gymnasieskolans etikundervisning kan beröras genom att låta olika element i Mass Effect-spelen möta ämnets stoff. Processen verkar ur ett didaktiskt perspektiv både berikande för spelkontexten och illustrerar komplexiteten hos etiska modeller och fattandet av etiska beslut.
