I ett bredare perspektiv är uppsatsen ett försök att uppmärksamma den i nationalekonomiska sammanhang negligerade entreprenören. Uppsatsen vidareutvecklar Claudio Michelaccis matchningsfunktion där teknologisk tillväxt får konstant avkastning om allokeringen till forskning och entreprenörskap är genomtänkt, något han finner stöd för i USA. Uppsatsen testar samma funktion på 23 industriländer och finner ett tämligen gott stöd för hans antagande..

Background: Since the early 60?s, the CAPM or Capital Asset Pricing Model, has been an invaluable tool for assessing an asset's expected return, assuming that the asset is added to an already well-diversified portfolio of assets. CAPM theory assume that the unsystematic risk can be diversified and that the systematic, market-specific, risk is determined by the Beta value, from the Greek ?. An investor who takes big risks expect higher returns.One of the CAPM?s basic assumptions is that disruption in the market is not taken into account.

Bakgrund: Det har tidigare konstaterats att det existerar ett samband mellan aktiers likviditet och dess avkastning. Bevis för detta har främst gått att finna på utländska aktiemarknader. På den svenska aktiemarknaden har tidigare utförda studier konstaterat att detta samband inte existerar. Vi vill därför göra en studie på den svenska aktiemarknaden, vilken delvis innefattar en ny tidsperiod för att se om någon likviditetspremie existerar.Syfte: Vårt syfte med denna studie var att undersöka om det är möjligt att uppnå en högre avkastning genom att investera i en portfölj med relativt sett illikvida aktier jämfört med en portfölj bestående av likvida aktier på Stockholmsbörsen samt undersöka om faktorerna likviditet, betavärde samt företagsstorlek signifikant påverkar portföljernas eventuella överavkastning jämfört mot ett lämpligt index.Metod: Vi har skapat tre olika portföljer, med tio aktier i varje vilka representerar de minst, mitterst och mest likvida aktierna enligt vårt valda likviditetsmått, aktieomsättningshastighet. Likviditetsmåttet laggar en månad för att kunna användas som investeringsstrategi.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Syftet med detta examensarbete är att optimera produktionen för högst lönsamhet för den planerade vindkraftsparken Hästkullen i Härnösand och Timrå kommuner. Arbetet har utförts för SCA Energy i Sundsvall. SCA projekterar vindkraftsparken Hästkullen i samarbete med EON.Vid en satsning för etablering av en vindkraftspark krävs investering på miljardbelopp. Det är därför viktigt att säkerställa att investeringen på sikt blir lönsam. För att kunna göra denna uppskattning krävs det noggranna produktionsberäkningar med tillgång till ett års komplett vinddata.Det program som använts för att simulera produktionsberäkningarna är WindPRO.

Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.

There are some hazards associated with mediating dogs for adoption to Sweden from foreigncountries. Contagion is considered to be one of them, but this report focuses solely on what adoptionsmay signify to the dogs concerning animal welfare. The aim of this study is to investigate how thebusiness in Sweden is run and what this can imply to the adopted dogs. Websites of the organizationswhich perform mediation of dogs, has been examined to show which information is available. A webquestionnaire was sent to these organizations to learn more about their standard procedure.

Vi har undersökt relationen mellan VD-ägande och företags aktiekurser på Stockholmsbörsen mellan åren 2002-2007. Denna undersökning har visat på varierande resultat beroende på hur portföljerna är viktade. Genom att titta på avkastningen hos de likaviktade portföljerna, har den med högst VD-ägande haft högst ren avkastning. Detta har vi dock inte kunnat säkerställa rent statistiskt. Däremot kan vi påvisa att Sharpe-kvoten har varit högre för bolag med högt VD-innehav i aggregerade portföljer för hela testperioden.

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

Problem: The question is if investors falls into psychological decision traps when they are about to make an investments decision. Research in other areas suggests that this may be case. The reason is that they are not aware of that psychological decision traps exist. If so, it can lead to pernicious consequences for the return on the portfolios they manage. Purpose: To investigate if investors fall into four different psychological decisions traps: anchoring, confirming evidence, overconfidence and regression towards mean, at investments in IPOs Method: We have collected data through a form of experiment.

The purpose of this study was to examine the initial and continuing trauma and its effects, and the coping strategies that these women develop in order to survive. The initial trauma occurs during the trafficking and seasoning process in the brothel. The term continuing trauma refers to violence and psychological trauma that are part of sex workers lives.

With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.

Denna uppsats utreder för ett urval av 80 länder hypotesen att inkomstojämlikhet mätt i ginikoefficienten har en negativ påverkan på ekonomisk tillväxt mätt i BNP/capita. Utgångspunkten är att finna stöd för tidigare forskning på inkomstojämlikhetens påverkan på tillväxten. Den empiriska undersökningen görs med linjär regressionsanalys i fyra modeller där tillväxt är den beroende variabeln, ginikoefficienten den oberoende samt ett antal kontrollvariabler för initial BNP-nivå, demokrati, utbildning, handel, livslängd, rättssäkerhet och korruptionskontroll. Resultaten visar ett signifikant, men svagt, negativt samband mellan tillväxt och ojämlikhet. Dock lider modellerna av möjliga problem med endogenitet samt multikollinearitet.

The foundation of our study is five strategically selected printed advertisements which all contains signs that refer to digital medias. Through a quality content analysis, we are studying how advertisers may use a room with extended communication too enlarge the space given in a printed advertisement. The potential in these rooms are proposing a social connection and a flexible interaction by providing content that is not possible to create in a printed advertisement. The form of communication is changing and there is a two-way communication created in an obvious way. The different kinds of roles in the communication process are here partially integrated with each other.

In todays society IT in general and the Internet in particular are given elements in people´s everyday lives, and smartphones has come to be a big part of those elements. This study focuses on how the use of Smartphones in particular influences the individuals in their working environment, and how this use influence the efficiency and the well-being of said individuals.  To answer our research question regarding how said use comes to effect the efficiency and the well-being for proffesionals in their working environment we have used data from qualitative interviews who is enriched by a short initial diary study. This data has then been analyzed using the Affinity Diagrams Technique, leading to four central themes emerging from the data. The results show that smartphone use at work comes with both positive and negative effects; efficiency increased through the use of smartphones due to the great versatility that comes with the technology, while in terms of well-being issues of stress emerged.
