Risk och osäkerhet i vindkraftsinvesteringar : Hur företagens investeringsbedömning påverkas av deras syn på risk och osäkerhetsfaktorer
Nyckeln till ett framgångsrikt och värdefullt företag är att göra bra investeringar eftersom det är investeringarna som skapar den avkastning som dess ägare får som ersättning (Froot, et al., 1994). Om företaget strävar efter att göra värdemaximerande investeringar måste de därför bedöma vilka investeringar som kan tänkas generera en avkastning som är större än kostnaden för kapitalet som investeras (Brealey, et al., 2014). Detta är den teoretiska grundregeln för all investeringsbedömning (Brealey, et al., 2014). Men eftersom framtiden är fylld av risk och osäkerhet är bedömningen av en investerings ekonomiska värde ingen enkel sak (Sandahl & Sjögren, 2005).I företagens strävan att tämja denna risk och osäkerhet har Mikes (2009;2011) identifierat två olika kulturer, den beräknande kulturen och den visualiserande kulturen. Dessa kulturer präglas av sin syn på vad som är meningsfullt att sannolikhets bedöma och vad som inte är meningsfullt att sannolikhets bedöma (Mikes, 2011).
Vardagsmat eller domedag? Marknadsföring av ekologiska varor genom svaga och starka rädslor
In a time when concern for the environment is a topic that is met with both love and hatred, organic goods and services become increasingly common on the market. Communication efforts with the purpose of increasing the proportion of organic products consumed are being conducted by both private and public actors. However, achieving attitudinal and behavioral change within complex areas such as this comes with many difficulties.Within public opinion change, a common way of achieving a change in behavior is to use fear appeals and scare tactics. Earlier studies have shown that messages prompting a low level of fear can be more effective than messages prompting a high level of fear, since a high level of fear tends to raise defense mechanisms in the consumer. The purpose of this essay is to examine whether fear and defense mechanisms is a problem when it comes to making consumers choose organic products, as well as studying whether messages prompting low levels of fear are more effective than those prompting high levels of fear.This quantitative study is conducted in the form of a questionnaire-based experiment, comparing the effectiveness of two messages prompting different levels of fear.
BIM Building Information Model : Hinder & Drivkraft
The construction industry is a costly business such in respect of capital for most construction defects which then require rework, tear down and rebuild again. This study is meaningful awareness of tools that can reduce this best through communication and information sharing between the parties. The construction industry is known as temporary projects organizations, where the construction project consists of several actors who have to communicate and share information between them to avoid mistakes later in the build time. These actors are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to create a routine for the association and the shattering of these actors. To implement such behavior using a tool such as BIM in the industry whose size perhaps is indescribable may be a very hard task. BIM (Building Information Model) could be seen as the solution to this problem because it acts as a portal where the actors involved must sign in and communicate, share information, and eventually create a behavior, a routine for this association and division of the actors following the end of the project. The technology could help the involved from the beginning of the project, already in the model stage, break down and prevent any construction barriers when the building has been placed in the works.
Value at Risk med Extremvärdesteori - En Studie av Råvaror
Det idag väldigt populära riskmåttet Value-at-Risk (VaR) kan beräknas på många olika sätt. En metod som använder sig av extremvärdesteori (EVT) för att estimera VaR utvecklades under 1990-talet som ett alternativ till de traditionella VaR metoderna. EVT fokuserar på fördelningens svans, eftersom det är här de extrema observationerna uppträder. I denna studie undersöker vi hur framgångsrik extremvärdesmetoden är när det kommer till att estimera VaR för råvaror, en typ av tillgång som karakteriseras av att vara extremt volatil och därmed speciellt svår att riskbedöma. Våra resultat pekar på att extremvärdesteorin erbjuder ett intressant alternativ när man önskar att estimera VaR för volatila råvaror.
Förekommer kränkande behandling? : En kvalitativ studie av förskolebarn och pedagoger.
The following paper is about degrading treatment in preschools and the essay discuss degrading treatment according to the Swedish school law, in preschools and the chosen focus for this study is three to four year old children.

The questions for this study are: Can children proceed with degrading treatment towards each other? Which conflicts evolve through children?s interactions? Can children in pre-schools have a degrading behavior? To answer these questions participant observation at two preschools and interviews with four preschool teachers were chosen as method. The perspective of this paper is based on the view on children as actors, which is used to acknowledge and enhance the possibilities of letting the children?s own voices be heard.
IP-telefoni - En explorativ studie om vad som påverkar konsumenters användande av IP-telefoni
Despite the fast growing development of IP-telephony services, only a small number of people in Sweden use them. Of the total amount of fixed telephony subscriptions, maximally five percent are based on IP-technology. Through an exploratory study, the main purpose with this thesis is to identify factors that influence the use of IP-telephony on the consumer market, and the factors? internal relationships. The thesis also has two sub-purposes: firstly, chart the supply of IP-telephony services and secondly, discuss what IP-telephony services that are requested by today?s customers in the future.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?
In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.
Hellre överkvalificerad än undersysselsatt - om övergångsfrekvensen till högre utbildning i Sverige under 80 år
This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.
Livsstil och livskvalitet året efter avslutad hjärtrehabilitering : en enkätstudie
ABSTRACTBackground: To be stricken with a cardiac infarction is among other things linked to different risk factors. Many studies show that the participants in cardiac rehabilitation programs learn to deal with the risk factors, increase their quality of life and lessen the risk for re-infarction.Objective: To describe the lifestyle and perceived quality of life of the individuals after having participated in cardiac rehabilitation program and to see if they had maintained their results up to a year after having a cardiac infarction.Method: The 19 individuals who had participated in cardiac rehabilitation in 2010 after having had a cardiac infarction were asked to participate in the study. Everyone agreed to participate. The study was made analyzing the surveys, one a locally made, that the individuals had filled out four and eight months after cardiac infarction, and the other the generic Quality of life questionnaire EQ-5D, that the individuals had filled out two and twelve months after cardiac infarction. Result: The individuals have not changed their lifestyle after having participated in cardiac rehabilitation which can be interpreted that they have followed existing recommendations. The mean weight increased with one kilogram, no depression is shown and they stress less.

Självskadebeteende och riskbeteende för ätstörningar hos tonåringar: förekomst, samband och intervention med expressivt skrivande
The purpose of the present essay, as part of the project Self esteem and Life circumstances among teenagers, was to investigate the rate of both deliberate self-harm (DSH) and risk behaviour related to eating disorders in 14-year-old swedish adolescents, gender differences in DSH, and possible correlations between DSH and risk behaviours related to eating disorder. In addition, the effects of expressive writing (Pennebaker & Beall, 1986) on DSH and risk behaviours related to eating disorders were investigated. Data from two pilot studies are included. In total, 198 14-year-olds from four different schools in southern Sweden participated. For the purpose of measuring the rate of DSH, a simplified version of Gratz's (2001) Deliberate Self-Harm Inventory (DSHI) was used.
