Since the year of 2000 it has been legal for companies in Sweden to repurchases their own stocks. The purpose of this study is to examine if it has been possible to make a positive abnormal return in Stockholmsbörsen by buying stocks in companies that has announced a buyback program. Our study includes 59 companies that have accomplished a buyback program throw the years of 2000 to 2006. To calculate the abnormal return we use the BHAR method with Affärsvärldens generalindex and branchindex as benchmarks. The result shows a significant positive abnormal return of 23,56 percent the first 12 month after the announcement with Affärsvärldens generalindex as benchmark.

Can we harm future people? According to our commonly used contractarian theories, it seems we cannot. This is because our actions of today not only influence what they are supposed to influence, but also who mates with whom and when, and thus which particular persons will ever live in the future. Had we not performed a particular action, the future people born as a result of that same action, would not have been born. It therefore seems they cannot reasonably reject our actions.

The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage.  The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment. The result for the portfolio consisting of stock recommendations show a positive return of equity in positive environment and the opposite effect in negative environment. The pattern that has been observed can be classified as an anomaly.

Is there a specific tradition of songs within the swedish environmental movement? What kinds of music has been performed in different situations and what does it mean to the movement and its inner life? The essay deals with a town meeting and action against plans of establishing passenger flights at a former military airport in Uppsala, looking at the action as a performance and as a ritual. The second part of the essay is built on interviews of three veterans of the movement's organisations one of which is as a singer-songwriter originally active in the peace movement of the 60's. The paper is about the songs and the situations in which they were sung, concluding that there is, the limited material considered, little evidence of considerable transfer of songs within the movement, though some coherence exists. The connection to between environmental movement and the swedish radical music movement of the 70's is also slightly mentioned.

This essay deals with the principle of surprise warfare and its development as well as the adaptation of military action that had to be made to surprise the opponent in the modern era.The concept of surprise is divided into its components in order to clarify what is required to implement a surprising maneuver, to understand the complex concept and form a theoretical framework for gathering facts in the case study.Development and adaption are demonstrated by a comparative case study where Pearl Harbor illustrates an example of historical surprise and Operation Desert Storm illustrates a modern surprise. The product will then be analyzed in order to detect the development and how military conduct is forced to adapt in order to carry out a surprising maneuver. The results shows that the military action of performing a surprise attack has had a major development and is now carried out in a different stage of the attack..

This thesis analyzes the consequences of ?Lex Uggla? ? a law concerning the boundaries between firm and individual with respect to wealth taxation ? for small businesses, with more than 3 million SEK in over-liquidity. There are two main findings of this thesis. Firstly, the wealth taxation of non-operational assets seems to be an inefficient tax which costs the Swedish welfare system much more than it generates. Secondly, the change in actions among entrepreneurs following the extensive news coverage following the tax authority?s charges against the company of the well-known artist, Magnus Uggla (hence ?Lex Uggla?) illustrates that neither changes of rules nor new applications of rules is necessarily sufficient for an agent to change course of action.

This thesis treats the topic of user-generated comments connected with news stories on news sites, meaning electronic word-of-mouth combined with PR. The writers have examined how different types of comments affect consumers' perception of the article and also what communication effects these comments generate in terms of attitudes, purchase intent and word-of-mouth intent. The results interesting to the news site owners, is that lots of comments and negative comments generate a negative effect by making the actual article less credible, attractive and worth reading (relative to the subsequent comments). On the positive side, serious comments imply that the news story is perceived as more interesting, than a news story followed by non-serious comments. From a brand equity perspective, the interesting results show that few comments compared to lots of comments, generate a better attitude to the brand, even though there is no difference in how positive or negative the comments are.

This is a study where the purpose was to investigate whether preschool teachers have a positive or negative attitude to outdoor education. Their view of outdoors education is also treated. The methods used were questionnaires and semi-structured interviews. The survey was sent to all preschool teachers in three municipalities and on a social network. The interviews were conducted at a preschool, which had a form of outdoor profile.

According to the Conventions on the Rights of the Child, children have the right to make their voices heard and express their opinion in situations concerning them. With this paper the authors have chosen to explore social worker?s view?s on children?s participation and influence, and how these are manifested through the entire case process. The focus in this study has also been the positive and negative effects the children?s influence may have.To investigate this, a qualitative study using semi-structured interviews has been conducted.

Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..

As the western society gradually turns into a knowledge- and risk society, where science and scientific innovations increasingly both promise to save the world and destroy it, a shift in the relation between the scientific community and the rest of society has emerged. A shift from a top-down one-way transfer view regarding communication, to a dialogue-based interactive co-production model, where the public are part of setting the agenda for research and contribute to the knowledge production. Or at least in theory, in EU documents and in many different country's policy documents. In practical application however, one might have a hard time see the implementation of such model.As a more comprehensive and dialogue-based science communication is depending on the possibility for scientist themselves to engage and fell the need to engage, we have focused on their thoughts.In this thesis we have examined six scientists view on, and work with, science communication, as well as their perceived social and structural conditions. We have also examined action plans and strategy documents from three Swedish universities that in different ways mention science communication and interaction with the broader society.

The purpose of this study was to highlight cyber-bullying and its place in today?s schools.

Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).
