Is it through systematic use of these portfolio strategies possible to beat the market index ? in other words does financial illusions exist? Purpose: To examine if the Stockholm Stock Exchange is an efficient market. Limitations: The efficiency is tested solely through the chosen portfolio strategies: low Price-Earnings ratio, low Book-to-market ratio and low stock prices.

Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..
Simulation av Xbox Live Indie Games gränssnittet
This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..
Regionen - Räddningen för utflyttningskommuner? En analys av regiondiskursen i två kommuner i Västernorrland
The analysis of regional development and the formation of regional policy have experienced an increasing importance in Europe and in Sweden during the last decades. There is a widespread assumption that the increasing significance of regions is due to the diminishing role of the nationstate in the era of globalization. This essay suggests that there is a hegemonic discourse, heavily relying on the assumptions of New Regionalism, when addressing regional building. Sometimes described as an ideology, New Regionalism, which is derived from research of successful regions, is based on the assumption that regional competitiveness and autonomy creates economic growth. The Committee on Public Sector Responsibilities (Ansvarskommittén) suggests that Sweden requires new regional structure, due to the increasing expenditures facing the welfare state.
Energieffektivisering i offentliga byggnader : Jämförelse i elanvändning för ventilation med olika luftflödesstyrsystem
I got interested in this subject when I came in contact with Västtrafiks new paymentsystem myself during my visits in Gothenburg. I suspected problems with the informationmaterial regarding it and others seemed to share my opinion that the payment system wasdiffcult to understand. When I contacted Västtrafik and asked them about the paymentsystem they confirmed that some understanding diffculties had occurred. With thatconfirmation I decided to make it my project to look in to the matter.Some methods were used to identify the problems. The methods could again confirm thatthere were some problems with the payment system and that the information material wasa vital reason.

With the world facing significant changes and natural disasters, there is an urgent need for action to mitigate environmental impacts to avoid devastating consequences.
Utveckling av ett kliniskt användbart status för patienter med reumatoid artrit som har höftledsplastik: statuset avser nedre extremitet
Det är vanligt att en patient med reumatoid artrit (RA) förr eller senare behöver ersätta sin höftled/leder med plastik. Efter en höftplastikoperation är vissa rörelser olämpliga för patienten att utföra. Idag finns inget status för bedömning av patienter med RA, som samtidigt tar hänsyn till en eventuell höftplastik. Syftet med den här studien var att utforma ett kliniskt användbart status för bedömning av RA-patienter som har höftledsplastik. Syftet med studien var också att statuset ska bidra till att göra statustagning för RA-patienten säkrare, i avseende att minska luxationsrisken.
Omval på gymnasiet
Genom praktiska och teoretiska studier på studie- och yrkesvägledarprogrammet har vi kunnat se en ökning av de elever som gör ett omval efter ett år på gymnasiet. Syftet med undersökningen var att se bidragande orsaker till att ett eventuellt omval sker. En kvalitativ studie har gjorts genom intervjuer med fem elever som gått ett år på sitt omvalda gymnasieprogram. Detta resultat har ställts i relation till Linda. S Gottfredsons teori kring begreppen begränsningar och kompromisser i studievalet samt SCCT-teorin där fokus ligger på självskattning.

Stress : En gransking av studenters stressnivå - Praktik och icke praktik
Practical and theoretical learning are methods that are used in schools as a way to prepare students for the working life. Within the practical learning knowledge is not only acquired to learn in practice, but the students must also be able to apply their theoretical knowledge to what he/she does. Against this background, the aim of the study was to investigate the importance of practical learning for students in college / university level and how they are experiencing the stress that may arise out of the loss of practical learning during their education, as well as their vision for working life after completing their education. The population of the study consisted of N = 36, which 18 of these had used both practical and theoretical learning and the remainder had only used theoretical learning. The method was a questionnaire survey with a high proportion of fixed alternative answers according to likert scales.
Koalitioner - ett kostsamt fenomen? : En studie koncentrerad till Sveriges kommuner
AbstractSince the 2006 election the country of Sweden is governed by four Liberal and Conservative parties. Parties that by cooperating maintain power in office and forms a so called coalition. A coalition that not only can be seen at the national but also at the local level. According to pervious research coalitions that holds control of the seats in the government at the national level tends to increase the total expenditures compared to other types of government formations. Can a similar connection be seen at the local level? This the fundamental issue of this essay.
Kontroll-lokus och beteende i grupp: en studie om sambandet mellan kontroll-lokus och individers beteende i en arbetsgrupp
The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.
Fäst vid keramik : En experimentell undersökning av lipidrester i keramik, med GC-MS-metod, efter nedbrytningsförsök
Thisis an experimental study of lipid residues within the field of laboratoryarcheology. Pottery was made in a time like manner and used to cook grain and Icelandmoss and exposed to an organized biodegradation experiment inside an incubatorfor later analyzes with the GC-MS-method. Tests were also taken from pottery,grain and Iceland moss that had not been exposed for a biodegrading attempt.The grain is a domesticated cereal and the Icelandic moss fungi-alga mix. Thetest results showed mostly saturated fatty acids, sterols and monoacylglycerolsof saturated fatty acids. Within the laboratory archeology, ergosterol has beensuggested as a possible biomarker for yeast and alcohol fermentation.
