Syfte: Undersökningens syftet är att mäta huruvida det går att få ut en överavkastning av aktier som väljs in i (respektive ut ur) OMX Stockholm Benchmark (OMXSB), som följd av att ett index ändrar sin komposition. Delsyftet är att undersöka om det går att se en signifikant ökning av handelsvolymen i anslutning till ändringsdagen.Metod: Studien tillämpar en eventstudie som undersökningsmetod av kvantitativ karaktär. Studien undersöker indexet OMXSB och innefattade totalt 111 stycken ingående och utgående aktier fördelat på 10 tillfällen. Två eventfönster har konstruerats; ett kring annonseringsdagen och ett kring ändringsdagen. Den procentuella handelsvolymen har mätts över eventfönstret kring ändringsdagen.Resultat: Den genomsnittliga kumulerade överavkastningen för eventfönstret vid annonseringsdagen uppgick till 1,02 % (-6 %) för de aktier som valdes in (ut).

With the rise of the internet especially and information- and communication technology in general, the opportunities for fast and effective communication and sharing of information have proliferated.

Haemophilia is an inherited disease which causes increased bleeding due to defect clotting factors VIII and/or IX. There are two forms of haemophilia, A and B, which both are X-linked and due to mutations of the genes of factor VIII and factor IX respectively. This study focuses on Haemophilia A and thereby factor VIII.The drugs that are available on the Swedish market today for patients with haemophilia A include Factor VIII(FVIII), which has been purified from human plasma and recombinant factor VIII(rFVIII). The main goal of this study is to gain a better understanding of the effects of treatment of haemophilia A with either purified plasma factor VIII or recombinant factor VIII on reducing or preventing bleeding and on side effects.  The study was designed as a literature review and searches were carried out in PubMed at the Linnaeus University library.  The criteria for selection of articles were: patients with haemophilia, treatment with plasma derived and/or recombinant factor VIII as well as clinical studies.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Aim: The purpose of this work is to investigate what differences there are between a credit union that is connected to Sweden?s Credit Association and an independent association, and how these differences have affected the union?s success. Method: A qualitative study has been made by means of email and telephone interviews. Respondents were chosen from Sweden?s Credit Association, Credit Guarantee Association in Gävleborg and Övre Norrland Guarantee Association. The interviews were then analyzed in the light of our theoretical studies. Result and conclusions: We have found that there are three major differences between the unions.

Australia is one of the largest producers and consumers of fossil fuels in the world. In a society where the effects of fossil fuels on global warming are constantly discussed, the nation?s production and consumption are subject to debate. Problems arise when negative aspects of consumption, such as emissions of greenhouse gases, are put in relation to an increased need of energy and economic growth. However, it is important to distinguish between different types of fossil fuels when it comes to their individual impact on the environment and to analyze the possibilities to increase the more environmental friendly ones.

 In his book Wittgenstein on Rules and Private Language (1982) Saul Kripke claims that Wittgenstein argues for a certain form of scepticism in his book Philosophical Investigations (1953), namely a new form of philosophical scepticism, a result of Wittgenstein´s idea of language as language games. Nihilism, scepticism of meaning or of concept, constitutive scepticism are other commentators´ different names of the same phenomenon. The philosophy of Wittgenstein accounts for how our words, including the words of mathematics, have no meaning and there are no a priori justified objective facts as to what I mean about a word. We follow the rules blindly and without justification. We are unable to find any facts against this proposal.

The aim of this study is to elucidate the process in which psychology was separated from philosophy and established itself as a distinct academic discipline in Sweden. I argue that the concept of will, as well as the concepts of thinking and emotion, have a lot to tell us about the rise of academic psychology in Sweden. This is done through an analysis of psychology textbooks, encyclopaedia-articles and academic texts on the themes will and psychology, from around 1800 till 1950.Prior to the establishment of the first chair of psychology in Uppsala 1948, the discipline was above all a part of the philosophical discipline. For psychology to become a science of its own, it was crucial to obtain a position among the empirical sciences. It thus had to distance itself from philosophy, and in particular from metaphysics.

Children at the age of six, has since 1991 been allowed to start their tuition in the Swedish school system. Studies reveal that; the first school year (preschool) can be a stressful task dueto the new environment, new friendships and higher expectations.The purpose of this study is to describe and analyze how the teachers perceive their own role in the transitioning process from preschool to school. This purpose required a method of qualitative complexion and therefore qualitative interviews were used. The material is based on four interviews with four different teachers. The teachers were asked the same question considering; the transition from preschool to school from a pupil point of view, their own role in that transition and their opinions on different educational tools.

Problem. Sponsorship has increased continuously during the 21st century, however, at the same time the public interest of traditional promotion has been diminishing. The meaning of sponsorship is a very diffuse and therefore the concept needs to be investigated. Due to the multitude of sponsorship and its impreciseness about its financial value, it is difficult to evaluate sponsorship for companies, especially when there is a difficulty in choosing a decent method for evaluation.Purpose. The purpose of this thesis is to investigate the concept of sponsorship, motives for sponsorship and evaluation of sponsorship according to the theory and give empirical examples of how these areas are being managed by companies.Method.

This case study is made on assignment of Södra, region Öst, as a part of a campaign promoting more active management of the oak forests in the region. Hardwood trees of good quality, especially oak, has a high value due to that the sawn material is highly estimated by the market. It is important that the Swedish oak forests are managed in a proper way in order to meet the future demand. Södra has therefore decided to increase the focus on oak in the Kalmar region and they would like to find out if continues cover forestry (CCF) under certain conditions can be an appropriate management model. The motive is to make use of the existing oak forests more efficient, not just considering well managed forests but also the more neglected oak forests, on poorer soils. Thus, the objective for this study is to examine if CCF is appropriate method in the three stand types; broadleaved mixtures oak forest, oak islet, and oak/spruce forest. Existing management models were surveyed in the literature.

Non-compulsory schools in Sweden should make use of the knowledge and experience that is available in society according to the aims and objectives of the Curriculum for the Non-Compulsory School System - Lpf 94. There are however only a few studies which have focused on the contacts between non-compulsory schools and society as represented by the business world in Sweden.The purpose of this study is to examine in what ways and to what extent non-compulsory schools are following the Curriculum by using the knowledge and experience of the business world. The perspectives have been: Which contacts in the business world and which working practices from the business world are implemented in teaching in non-compulsory schools? In what way do these contacts and working practices affect the teaching and learning of business administration? The purpose of this study is also to examine if the teachers in non-compulsory schools use business information and different kinds of business knowledge and experiences in order to keep themselves up-to-date regarding the business world. The perspectives have been: Are the teachers using up-to-date business information or business experience? Are the teachers applying a multicultural perspective in teaching business studies? In what way does this kind of information or first-hand experience affect the teaching and learning of business administration?The method used in this study was to interview seven teachers from two non-compulsory schools in Stockholm.

This thesis concerns how Sweden relates to life cycle assessment (LCA) in the construction process. LCA means analyzing a products impact and the analysis includes the whole life span of the product. A building has a high complexity and the combination with its unique shape will make the LCA more comprehensive, unlike e.g. aluminum cans. Recently there has been a development of a working procedure in the construction industry.

This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.
