This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

In the light of new technology health care is now given the opportunity to form a more mobile way of working that would bring about potential gains in terms of efficiency and quality. On the other hand, a more mobile health care also requires a more generous handling of personal information, something that may raise issues in terms of privacy. This study shows that the privacy of the patient requires two things: (i) that the personal information of the patient is handled in a way that generates her an overall positive expected utility and that (ii) the negative expected utility that each risk of an information leakage causes is offset by the expected utility it also makes possible. The first requirement (i) is shown, in comparison with today?s way of working, to be met due to the potential gains in efficiency and quality in combination with no increase in the probability of informational leakage or negative effects of such a leakage. The second requirement (ii) was also considered met since no separate risks of information leakage could be identified that was not offset by the gains it made possible in terms of expected utility..

The aim of this thesis was to investigate how the use of the IT-personnelsystem influences human resources and the new challenges and future requirements that may occur, while IT-personnelsystem is used more extensively in the HR-function.Previous research referred to in this study, has focused on how the HR-transformation has contributed to the development of an IT-personnelsystem, which has been used with increasing frequency. This use has created a significant change in the HR-function. This thesis focuses on investigating, describing and analyzing how the practice and development of the IT-personnelsystem meets the needs of the HR-transformation.This study uses qualitative research methods to investigate sixteen users? experiences and our understanding and conclusion is based on both semi-structured interviews and webb surveys. Initially deductive, later on our study took a more abductive approach.The result indicated a variety of uses for a specific IT-personnelsystem dependent on the users? function and positions and also how HR-activity was organized within the business.

Examensarbetet handlar om en jämförelsestudie av beräkningseffektivitet med avseende på energi- och tidsförbrukning mellan grafikkort och processorer i persondatorer och PlayStation 3.Problemet studeras för att göra allmänheten uppmärksam på att det går att lösa en del av energiproblematiken med beräkningar genom att öka energieffektiviteten av beräkningsenheterna.Undersökningen har genomförts på ett explorativt sätt och studerar förhållandet mellan processorer, grafikkort och vilken som presterar bäst i vilket sammanhang. Prestandatest genomförs med molekylberäkningsprogrammet F@H och med filkomprimeringsprogrammet WinRAR. Testerna utförs på MultiCore- och SingleCorePCs och PS3s av olika karaktär. I vissa test mäts effektförbrukning för att kunna räkna ut hur energieffektiva vissa system är.Resultatet visar tydligt hur den genomsnittliga effektförbrukningen och energieffektiviteten för olika testsystem skiljer sig vid belastning, viloläge och olika typer beräkningar..

Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

The aim of this qualitative study of service work in the private sector is to examine how the service worker experiences his/her work. There are three dimensions of the service workers experience in focus, and they are the base of my formulation of questions. The first dimension refers to how the service worker experiences the emotional labor demands from the employer. The second dimension concerns the relation between service worker and customer, from the view of the service worker. The third dimension problematizes how service workers experience efficiency.I have interviewed three call center customer workers and two hotel receptionists, using semi-structured interview technique.

Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

The main purpose of this thesis is to analyse the possibilities and problems facing a privatised work injury insurance. This discussion includes the element of premium differentiation. Todays´ Swedish social insurance system is ineffectively formed. The costs have dramatically increased during the 1990´s. The Swedish government is now looking for ways to improve the efficiency of the system.

The thesis aims to examine how companies optimize the human capital from a value creation perspective. The value creation will be related to transfer of knowledge, recruitment, staff turnover and development. The thesis has a deductive approach and six qualitative interviews have been conducted. The results from the interviews will be strengthened with a quantitative data analysis of two measurements; value added per employee and human capital efficiency. The theoretical framework includes definitions of human capital.

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

This thesis is an evaluative study of the political reform, Friskolereformen, which enabled independent schools to receive state funding. The study evaluates to what extent the incentives, which preceded the reform, have been fulfilled. The evaluation is defined to include upper secondary schools in the municipality of Halmstad during the years of 2005?2010. The reform was enacted on the basis that it would result in a higher standard of quality, efficiency and freedom of choice.

In 2005 the Swedish government introduced a law of amnesty for refugees in the country which made the Minister of Integration invite a number of national organizations to discuss this law. After that, seven organizations in Gothenburg also felt that something should be done and they started talking about a cooperation to improve the situation for newly arrived people to Gothenburg. They formed a project, ?Plattform Göteborg?, which in this paper will be evaluated according to a manual from Sida. The project consists of seven organizations which have their separate activities formed by them to improve the integration.
