Dolda vinstmöjligheter : En studie om överavkastning vid ändring av indexkompositioner
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).

Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.
Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.

Mångfunktionella golfbanor : rekreativa och pedagogiska platser
The objective of this essay is, from the golf perspective including the golf courses' physical attributes, golf club management, members of the golf club and golf course designers, to explore possibilities for making existing golf courses more multifunctional. The purpose of this is to increase the understanding for golf courses' role as part of the landscape and comprehension regarding possible opportunities around them to exploit and develop.The increased pressure of population in peri-urban areas has resulted in a greater need for accessible recreation, particularly in the isolated farmland. As a result, land is sometimes used against landowners' will, which is a deficiency that is the basis for many conflicts between farmers and landowners.In the current situation, there is a negative trend in golf with reduced interest and fewer golfers than in the past. As a result, many of Sweden's golf courses have financial problems and are therefore trying to find new ways to avoid bankruptcy. Sweden's existing golf courses occupy about 30 000 hectares of land, of which a very large percentage are located in peri-urban areas.
Avspecialisering som framgångskoncept för jämnare arbetsfördelning?
The application of the LSS law and how the public organization (Municipality of Hudiksvall) later had to reform their organization to fit the new demands is the foundation to this master's thesis. An internal evaluation was performed due to this reorganisation process within the social care department (LSS unit). The aim was to investigate and evaluate if the reorganization resulted in a better working environment and if the work load (distribution of work) became more evenly divided between the different unit managing directors. The primary empirical information to this master's thesis is collected from that evaluation report. The main aim of this master?s thesis is to answer if the organisational choice between specialised or de-specialised working tasks has an effect (experienced and measured) on the level of stress among the unit managing directors.
Lokaliseringsutredning för nytt hotell i Sandvikens tätort med stöd av multikriterieanalys
The municipality of Sandviken is in a state of strong growth. This affects the need for more hotel rooms in Sandviken, in a way that it?s profitable to invest in a new hotel. Sandvikens largest company, the steal industry Sandvik AB, grows just like Sandviken, and have great influence on the need of more hotel rooms. Today there are three hotels placed in Sandviken, and these hotels aren?t enough when the pressure of hotel guests is at its top.The purpose with the project was to analyse the criteria?s that are important for localization of a new hotel in the Sandviken, and to clarify what kind of hotel Sandviken is in need of.
Distansledarskapets spelregler - en fallstudie av utlokaliserade journalisters upplevelser av distansledarskap och arbetsmotivation
What is e-leadership and how can it be framed in a distance context? How can work motivation be understood as a correlated theme? In prior leadership research and theory it has been taken for granted that leadership occurs in a face-to-face environment, so how to study leadership in a remote context? According to recent research, e-leadership defines this leader-member relation in this new arena, and a central focus of this research has been on communication. Communication is a central theme in the remote setting because it is the only interaction arena which allows leadership to be seen and understood. By conducting a case study in a multi media organization with distance working journalists as focus group this essay aims to bring a deeper understanding of how e-leadership works and how it effects work motivation. The field of media organizations is interesting to study as distance work is not an unusual working environment for journalists, and research has indicated that work motivation needs for these highly specified creative workers are somewhat differentiated from other, for example industrial workers, which implies that motivation theories urges an update.

Grundvattenavsänkning vid tunnelbyggnad ? tillämpning Förbifart Stockholm.
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Nerver i karpala flexorretinaklet på häst
The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.
Kör så det ryker! - En studie om prestationsångest i samband med ensembleundervisning
Title: Go for it! - A study of anxiety in relation to students performing in ensemble class.This study discusses anxiety in relation to students in ensemble performance. The expectations on musicians are extremely high and demanding. They are expected to perform to the maximum of their ability despite both physical and mental pressure. I present in this study the result of the interviews I have performed with three students at Swedish Academies of Music. The study shows that all of the students included are in one way or the other suffering from anxiety in relation to performance.
Vilka faktorer påverkar konkurrensförhållandet mellan en kommunal och en fristående gymnasieskola : en jämförelse av gymnasieskolornas ekonomistyrning och verksamhetsstyrning
When the independent upper secondary schools were started in 1992, it meant a change in the competitive relationship for the local upper secondary schools. A reduced number of students during some years ahead, while the number of independent upper secondary schools increase will probably result in tougher competition between upper secondary schools.The purpose of this study is to review and compare financial and performance management between a public and an independent upper secondary school. The dissertation will focus on the now existing competitive relationship between the two types of upper secondary schools.The theory underlying the study is Porter's model - five competitive forces. The model is applied to the local upper secondary school and used to identify competitive factors affecting upper secondary schools. The study is using a qualitative approach with five interviews at two upper secondary schools, one independent and one public, located in the same town.The comparison of financial and operational management of upper secondary schools indicate that the differences are not as great as we first imagined, but that there still are some differences.
