To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

171 miljoner människor i hela världen har diabetes enligt World Health Organisations (WHO) senaste undersökning år 2000. Den kroniska sjukdomen påverkar individens hälsa och syftet med magisteruppsatsen är att undersöka om diabetiker har fler sjukskrivningstillfällen och sjukskrivningsdagar än icke-diabetiker? Uppsatsen empirisk data kommer från HILDA (Health and Individuals Longitudinal Data and Analysis) och teorin baseras på Grossmans ekonomiska teori om individens hälsoinvesteringsbeteende (2000) samt Kristian Bolin et als (2002) utökning av Grossman teori. Ekvationerna i uppsatsen bygger på teorin men det är nya hälsomått på efterfrågan på och investeringen i hälsa; sjukskrivningsdagar ? respektive sjukskrivningstillfällen.

Tourism is often being viewed as one of the worlds largest sectors and a great contribution to growth and development. There is a large motivation amongst developing countries to promote themselves as a tourist destination, since they expect the tourism to generate economic growth. The government of Thailand has been promoting tourism since 1960, and the number of foreign visitors has increased from 100 000 back then to 13.5 million in 2006. The purpose of this paper was to investigate weather the increasing tourism industry in Thailand has pulled resources away from other sectors of the economy towards the tourism sector, and in that way harming Thailand?s international competitiveness and causing deindustrialization.

This study is focused on small scale water and wastewater handling in Sweden. The study is divided into two major parts; the first describes common methods for water- and wastewater handling and the second part is a case study on three small and expensive systems in Gällivare municipality, in the north of Sweden. In the case study, abilitys for the local government to hand over unwanted systems to the water users is investigated and found to be a plausible solution to cut costs for two out of the three studied systems. In the third case, water and wastewater systems is not recommended to be handed over but other ways of cutting costs are suggested..

The Sub-Saharan countries have for a long time struggled with poverty and conflicts which might have proven hostile for investors. The analysis aims to see if there is a significant correlation between foreign direct investments (FDI) and economic growth and which cultural and institutional factors seem to be significant in this correlation. Considered are also other variables and their influence that might explain what motivates and gives incentives for foreign direct investments (FDI) and are used in the construction of a regression analysis. This to see whether there is an effect on the economic growth in relations to FDI. The results show that FDI is of significance to the economic growth in the region and the study shows that corruption seems to be the most significant institutional factor in the correlation with effect on economic growth and the ability to attract FDI..

Certifications is common for IT in relation to individual program languages or program applications. Certifications for educations that endures several years is not as common to see. In this paper the situation for the Systems Science programme is researched, by investigating how the programme looks around in Sweden. Also by using interviews, show how companies and people responsible for the programme in Umeå, think the contact is between them and how the knowledge of the Systems Science students are from the view of the companies that employ them. In the end the conclusions show that there are differences in the Systems Science programme, and that the companies have quite a similar view of what the Systems Science students are good and not so good at.

Samhällets resurser är begränsade och en prioritering av olika verksamheter nödvändig. Cost-utility-analysen är en typ av ekonomisk utvärdering som syftar till att utgöra en del av beslutsunderlaget vid prioriteringsbeslut. Uppsatsen gör en cost-utitlity-analys av den ickefarmokologiska hypertonibehandling som genomförts vid Vindelns hälsocenter på individer där traditionell behandling inte haft önskvärd effekt på blodtrycket. Det sänkta blodtryck deltagarna på internatet erhöll minskar riskerna att drabbas av hjärtinfarkt eller stroke. Cost-utitlity-analysen inkluderar både till behandlingen relaterade kostnader och inbesparingar samt framtida till behandlingen orelaterade kostnader, som en följd av att individiden lever längre när riskerna minskar.

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

SammanfattningDenna uppsats utreder sambandet mellan privatiseringsreform av vattendistribution och det teoretiska begreppet ojämlikhetsfällan. En ojämlikhetsfälla är ett tillstånd av relativ brist på tillgångar och möjligheter, skapat och bevarat av en snedvriden institutionell miljö. Vår frågeställning är huruvida ojämlikhetsfällan som fenomen består efter en genomgripande privatiseringsreform. Det fall som vi undersöker är Buenos Aires, som 1993 genomförde världens hittills största vattenkoncession. Koncessionen annullerades 2006, sjutton år i förtid.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

In the light of ever increasing international trade around the globe, affecting men and women in all countries, it is surprising that so little attention is given its gender effects. The effects of trade are said to be gender neutral, but could potentially act reinforcing on the existing gender patterns in a society. The aim of this thesis is to examine whether the implications for men and women in relation to trade liberalization can be found to differ. By stylizing some differences between men and women, this is done by examining the theoretical implications mainly via the Heckscher-Ohlin model and through a Beckerian approach. The implications found are then compared with the findings in existing empirical work.

Syftet med vår uppsats var att med hjälp av Model Confidence Set (MCS) finna de bättre presterande modellerna bland de mest ?kända? och undervisade volatilitetsmodellerna. Vidare har vi även rankat dessa modeller inbördes. Eftersom prognoser om volatiliteten är mycket viktigt vid prissättningen på derivat, i detta fall ett räntederivat, är ämnet ständigt intressant. Med Model Confidence Set fann vi ett set av bättre presterande modeller utifrån vårt urval av ursprungliga modeller.

Syfte: Uppsatsens syfte är att undersöka huruvida det går att skapa överavkastning påden svenska aktiemarknaden genom att använda sig av strategin 52?week highmomentum. Uppsatsen syftar även till att undersöka huruvida eventuell överavkastningkan härledas till bolagsstorlek. Metod: Aktierna i dataurvalet rangordnas i förhållande till sina årshögsta. Portföljenkonstrueras genom att gå lång i de 30 % av aktierna som ligger närmast sitt årshögstaoch gå kort i de 30 % av aktierna som ligger längst ifrån sitt årshögsta.

Hedgefonders investeringsstrategier och överavkastning En hedgefond är en fond med ett avkastningsmål som är absolut och oberoende av marknadsriktning då förvaltaren inte jämför hedgefondens avkastning med ett index. Denna typ av fond har vanligtvis stor flexibilitet i förvaltningsinriktningen, de kan använda sig av såväl långa som korta positioner samt utnyttja belåning och derivat för att ytterligare öka avkastningen. Hedgefonder har under 1990-talet växt kraftigt och som en följd av detta har hedgefonder blivit intressanta som studieobjekt för akademiska undersökningar och forskning. Intressant ur en investerares synpunkt är att studera om hedgefonder kan påvisa signifikanta överavkastningar. Vi fokuserar på fondernas avkastning i relation till vilken investeringsstrategi som fonden har valt och utvärderar fonderas prestationer med hjälp av tre ekonomiska modeller; CAPM, Fama-Frenchs trefaktormodell samt en betingad trefaktormodell.

The increasing administration in IT-systems is the target of much debate today. It is viewed as taking time from what is considered to be managers? real tasks as well as resulting in an ineffective and stressful work environment. This view of IT-systems as problematic and time consuming can also been found among unit managers in a municipality in the north of Sweden. To be able to understand why IT-systems are perceived in this way this study?s aim has been to find what leads to this view.
