Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

To start a company on the Internet is something that has appealed a lot of people during the last couple of years. Some of the companies have succeeded in their struggle but a lot of companies have failed to live out their ambition. This paper deals with the concept of e-commerce and aims to study whether or not the companies that has succeeded has made use of business models and what other factors that is important that you wont find in any written theory.The paper also aims to study the concept of business models and what a business model consists of. To be able to do this research we have interviewed three different companies that are all active in e-commerce and have survived for at least three years. Two of the companies are classical web shops that sell products to their customers and the last one is a site with articles about hardware and IT business in general.

The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

The thesis analyzes two different approaches towards responsive web design, Mobile-first and Desktop-first. Responsive web design is a concept for websites whose design is customised based on the screen size. The analysis is performed by collecting views on the methods and also analyzing the usage of mobile and desktop internet to create a prototype of a responsive website where both methods are beeing used.The main difference between the methods is the foundation, where one is designed for mobile and the other for desktop. The thesis indicates that Mobilef-irst gives a better result for the mobile, which unlike the computer has poor performance, smaller screen and poor internet connection, therefore an advantage for the device that needs more focus to maintain a fast response. Desktop-first does not take this opportunity, but focus instead on the computer where the performance is better, which leads to a unnoticeable difference in response time.

Abstract Title: Coaching Leadership - A win-win situation? Level: Final assignment for Master Degree in Business Administration Author: Helena Gustafsson Supervisor: Pär Vilhelmson Date: 2012 ? mars Aim: The purpose of this study is to examine how companies use the coaching leadership and how the employees perceive to have a manager who uses this way to lead. Method: The study was conducted as a qualitative study in which interviews was an important feature. The information I gathered is the basis for analysis and final discussion. The material has been collected through personal interviews with two managers and then I send questions to the employees by e-mail that they responded. This is to get such an interesting empirical data as possible.

Syftet med studien var att med en experimentell design undersöka ifall individens tro på sin förmåga, d.v.s. self-efficacy påverkar utfallet av idrotts prestationer. Detta undersöktes genom att manipulera self-efficacy i en bänkpressövning och därefter mäta eventuella prestationsförändringar under tre sessioner. 21 deltagare (10 kvinnor, 11 män, M = 23, SD = 2.95) med lite eller ingen tidigare erfarenhet av styrketräning deltog. Deltagare delades slumpmässigt in i tre grupper: (LG) lättare vikt än deltagarna trodde, (TG) tyngre vikt än deltagarna trodde och (KG) kontrollgrupp, vikten överensstämde med deltagarnas uppfattning.

The high debt levels experienced in European Countries have lead to academic interest in the deficit bias -the tendency for governments to run budget deficits and accumulate debt. In part one of this thesis a surveyof the economic literature on the origins and solutions to the deficit bias are conducted. The proposedinstitutional solution to the deficit bias in the form of Fiscal Policy Councils (FPC) are outlined and existingEuropean FPCs presented. Based on the works of Calmfors and Wren-Lewis (2011) the EuropeanCommission (EC) is defined as an FPC. Based on this survey, two hypothesis are formulated: (1) theforecasts of future macro-economic events and fiscal performance will differ between the national FPCs andthe national government.

Background: The strategic importance of purchasing departments is increasing, yet supply risks are rather uncharted. The procurement of coffee involves supply risks and the purchaser needs to be able to handle these to enable the roasting-house to produce coffee as specified. Purpose: To chart risks in connection with the procurement of coffee as well as the possibilities of handling these. The thesis also examines if general risk management theories are applicable on the supply risk present within Swedish roasting-houses and can become an integral partof the purchasing process. Method: A qualitative case study of the purchasing process of Swedish roasting- houses.

Today?s farmers are constantly affected by the fluctuating world market prices on grain and thereby the price risk that comes with the price fluctuations. The volatile prices of grain increase the price risk within the business, which in turn affects the profitability of the business. The fluctuating prices together with the increased price risk within the farm business have opened up the market for hedging instruments. In this master thesis project, the aim is to identify the underlying end-values of 30 Swedish farmers? related to their choice of using hedging and the product; forward contract.

To become a successful athlete requires several different components in which one of themost significant is the ability to develop their own physical strenght. What weight exercises has the best transfer effects for skating?Participants in the study were 20 male senior hockey players from Div. II in the Västra Gö- talands Regionen in which all participants had at least 10 years of hockey experience.Test subjects had to perform a five-minute individual warm up followed by an opportunity to familiarize with the upcoming exercise. The first on-ice test was a 35 meters sprint test and the second test was an S-cornering agility test.

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
