This paper is a study how students at a high school in Falun, Sweden, estimates theirperformance in an upcoming math test which is then compared with the actual grade thestudent performed. The students who participated also answered questions related to ?risksituations? to examine whether there is a correlation between how students estimate theirperformance in the context and their risk behavior, and if the students act like economicmodels assume. In agreement with previous studies, the boys in the survey tended to beoverconfident in their performance. The girls in the study were neither over- norunderconfident in her performance and no significant difference in the estimation of one'sperformance between the sexes could be proven.

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..

An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory.

This thesis aims to investigate the information effects of fair value accounting in Nordic real estate companies. As a consequence of the mandatory IFRS adoption in the European Union in 2005, listed Nordic companies are allowed to recognize investment property at fair value in accordance with IAS 40. Theory suggests that fair value accounting should lower information asymmetry. Therefore, this study aims to examine correlation between fair value accounting of investment property and information asymmetry on the stock market. To investigate this, we use bid-ask spread as a proxy for information asymmetry and examine Nordic real estate companies before and after the implementation of IFRS.

The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

During the Nordic Bronze Age, houses were not exclusively connected with profane contexts, but did also feature in burial places, a peculiar fact when considering the careful separation of settlements and graves. What kind of houses do we find in these sacred contexts? What did these houses stand for? Why was the house symbolism chosen to accompany the dead? And why did the house symbolism flourish during the Nordic Bronze Age? To answer these questions three representatives for the house symbolism in Sweden are discussed in more detail, such as the burial in longhouses, peculiar houses called cult houses and house urns. Further, the phenomenon has been put in its temporal, geographic, social and ideological context, where aspects such as trade and settlement structure are presented. The house symbolism is, however, not confined to northern Europe.

In Scandinavia the general idea of the Bronze Age society is that it was organised as chiefdoms. The model for what they looked like is taken from the anthropological studies of the Polynesian chiefdoms. The aim of my study is to investigate a Scandinavian Bronze Age feature, known as cairns mainly containing fire-cracked stone. This is compared with how people in different Polynesian chiefdoms, looked at similar remain. This is done to get a background for new ways of interpretation of such remains.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

This is a non-traditional examination paper written after three years of studies at Malmö University and the Kaospilot Program. It is written in Swedish and in the spring of 2009. It describes a non-linear project based on a process-orientated theory called Theory-U by Otto C. Scharmer (2009). The project aims to investigate the changing conditions of Stage Theatre and deals with non-linearity as phenomena.

The reason for, and objective of, this project has been to research the relation between abstract and figurative illustration and how, if at all possible, one can bring them together and make them act as a whole.As a starting point for this project I used fragments from texts I?ve written during the past years. The texts deal with the thoughts and emotions that describe the state of melancholy or mania, two psychological conditions that are widely spread in our society. By illustrating these text passages in pencil drawings I?ve been given the possibility to investigate how to combine figurative illustration with the abstract alike.
