En studie av säsongs- och branschanomalier på den svenska aktiemarknaden

Purpose: The purpose of this study has been to investigate whether Frennberg & Hanssons earlier study of anomalies still are correct, and if these are valid for certain sectors. Methodology: In an effort to find seasonal patterns on the Swedish exchange market, we have used the average daily returns. By using these patterns we have created investment strategies which have then been tested over a 10 year period. We also used t-tests to verify our results. Conclusions: We have been able to prove a change in the seasonal patterns that Frennberg & Hansson presented in their study.

Crash Boom Bang : En kvalitativ studie om estetik och användarvänlighet vid produktion av en extremsportares webb

?Between normal and abnormal? is a qualitative literature study about adults with Aspergers syndrom. The study aims to understand how a person with Asperger syndrome understand himself. The study is built around two issues. These are; how does a person with Aspergers syndrom describe himself and how does the diagnos influence the self-image.

En studie om vad som behövs för att skolträdgårdar skall fungera under en längre tid : en utvärdering av Edane skolas skolträdgård

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

Hur viktig är statens styrka för ekonomiskt välstånd?- En studie av alla världens länder

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Pelletskvalitet : Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro

Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.

Från vilda till domesticerade djur - kan man gå ett steg längre?

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Den svenska kärnkraftspolitiken : En processpårande fallstudie av svensk kärnkraftspolitik

This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.

Analys av institutionell kapitalförvaltning: Stiftelserna som bildades ur de forna löntagarfonderna

This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.

Ideella uppdrag : Vad får någon att engagera sig ideellt?

This is a study about engagements and motivation. Its purpose is, by looking at other motivational theories than Abraham Maslow?s hierarchy of needs, to find out why certain people choose to become engaged as student representatives. The question this study is working from is: why do certain people choose to engage themselves as student representatives?This study has a qualitative approach, which means that a number of interviews have been done and subsequently profoundly analyzed.

Marknadens värdering av redovisningskvalitet

The purpose of this thesis was to investigate whether accounting quality is a priced factor by investors. The event studied is the release of year-end result and the release of the annual report. To assess accounting quality a sample of 30 companies listed on the Stockholm Stock Exchange during 2003 to 2007 are studied. We assess accounting quality by the absolute size of discretionary accruals using the modified Jones model developed by Dechow et al. (1995).

Evaluation of Capital Structure Arbitrage in the Equity-Credit Markets

Purpose: The purpose of this thesis is to test for the existence of Capital Structure Arbitrage oppertunities in the equity-credit markets. Methodology: The mispricing of Credit Default Swap contracts are calculated and used as input in an Equity-Credit market trading strategy. The returns are then evaluated with a modified Value-at-Risk simulation. Theoretical perspectives: A Merton-based structural model, CreditGrades, is used for credit pricing and a mispricing-convergence trading-strategy between the credit and equity markets is implemented. Empirical foundation: Daily quotes for the Credit Default Swap spread of 37 European firms were collected for a period of two years, as well as equity-prices for the same period and the previous two years, used for model calibration.

Ungdomars samtal om sexualitet : En narrativ studie om ungdomars samtal med gymnasiekuratorn

Adolescents are coming to high school counselors to talk about sexuality for various reasons and the purpose of this study is to gain an enhanced understanding of how adolescents in high school talk regarding sexuality and LGBTQ. The empirical material is assembled on eight narrative interviews with high school counselors. The school counselors have through their experiences in meeting adolescents, submitted stories about the adolescents´ conversations regarding sexuality to us. The empirical data were analyzed by a standard critical perspective and with the help of heteronormativity it made norms about what is normal and abnormal visible and problematized. The result demonstrates that adolescents are influenced by norms of society, the media, family and friends.

Sensory nerve conduction studies in young adults for the expansion of a reference material

Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.
