Black-Scholes : En prissättningsmodell för optioner

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

Administrativ styrning möter akademisk frihet Om Lunds universitets översättning av populära organisationsrecept

In a world of ?formal organizations?, which is constantly exposed for institutionalized super standards and ideas of a what a modern orgnization should be like, the pressure for changes are strong. This is the environment in which Lund University finds itself. Ideas in the beginning of the 21-century is concerning a stronger emfasis on steering, centralisation, re-hieriarchyzation, standardised processes and a new regulation concerning internal control. Through theories of new institutionalism, with conceptions as organizational identity and the expectations of adapting to new ideas, can you track the translation and adaptation that the ideas go through at the university- a decentralised organization where not only freedom has been a concept for the academic parts, but also for the administration.

Fördelning av resultat på den svenska börsen

This paper replicates a test performed by Burgstahler and Dichev (1997), which identifies a kink in the frequency distribution of earnings for companies listed on American stock exchanges. Their claim, that the kink is evidence of earnings management, has however been dismissed as a methodical consequence. To address this concern, this paper not only replicates the test in general, but also performs tests on a split sample, where founding family-owned companies are separated from the others, since earlier research has shown that founding family ownership is correlated with less earnings management. The results are in line with the findings of Burgstahler and Dichev, with a significant kink in the frequency distribution in the general test. The findings also show that the significance of the kink increases in the non-family-owned sample, while it disappears in the family-owned sample.

Sura Gamla Kyrka : analys av patologiska och skeletala förändringar hos sju individer

Seven individuals from Surahammar in Västmanland Sweden are analyzed for the appearance of pathological and skeletal changes. The graves, all from within the walls of a fourteenth century church, are dated from the Viking age to late eighteenth century. The aim of this scientific essay is to find pathological conditions by doing an osteological analyze, x-ray analysis, an osteoporosis measurement and letting orthopedists assess the individuals. The aim is also to say something about the individuals? general health and how they experience the changes they have in the skeleton.

Elektroniska böcker ur ett användarperspektiv - En studie av utlåning via Internet

Elektroniska böcker är ett relativt nytt koncept som inte riktigt gjort några stora landvinningar, trots att ny teknik kommit och framsteg görs. Syftet med uppsatsen är att se vilka brister som finns i utlåningssystem för e-böckerna. Med hjälp av en kvalitativ undersökningsmetod tar vi en närmare titt på Malmö och Lunds stadsbiblioteks hemsidor. Intervjuer av bibliotekspersonal och användbarhetstest samt en teorigenomgång är basen för vår undersökning. Med hjälp av detta ville vi se vilka brister som fanns vid utlåning, ur ett användbarhetsperspektiv, och dra våra slutsatser utifrån de resultat vi fått.

Textens inverkan på matematiska uppgifter : En undersökning om elevers textförståelse av matematikuppgifter i årskurs 5

The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.

En retrospektiv epidemiologisk studie om hudproblem på dobermann :

It is a well known fact today that suffering due to skin disorders is one of the most common causes to veterinary calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated problems causing veterinary visits of Doberman at four different veterinaryclinics in Sweden retrospectively, and compare these results with dogs in general and three other working dog breeds with the help of information collected from Agria - a Swedish animal insurance company. The total amount of veterinary calls that were registered at the clinics in question during the time of the study was 2460 visits. From these, 658 visits were due to skinrelated disorders, which amount to 27%. The most frequent cause to skinsuffering was injury caused by trauma, 15,7% of the Dobermans that were included in the study were affected, the second most frequent cause was inflammatory and infectious skin problems with 12,3% followed by neoplastic changes in the skin with 7% of the Dobermans affected.

En kvalitetskontroll - Snustillverkaren Fiedler & Lundgren kvalitetstestas

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

Tillgänglighet på svenska folkbiblioteks webbplatser en kvantitativ tillgänglighetsstudie

Information technology has become an integral part of our everyday lives. The Web is an important part of this development, however, web pages can be inaccessible to many groups of users. The purpose of this thesis is to examine the accessibility of Swedish public library websites. Besides examining the general accessibility, this study also covers whether any specific aspect of accessibility is particularly poor and if so which groups may be affected. In addition, this study also examines whether a correlation can be found between the degree of accessibility and the size of the website.

Lärobokens roll i matematikundervisningen. : Allmändidaktisk tillämpning av van Hieles teorier vid introduktion av algebra.

Detta arbete är en textanalys av hur några svenska läroböcker i matematik introducerar algebra speglat i van Hieles teorier om tankenivåer vid inlärning. Van Hieles teorier poängterar språket som kunskapsbärare i matematik vilket går som en röd tråd genom analysen. Generellt börjar läroböckerna på van Hieles tankenivå 3. Enligt van Hieles teorier borde undervisningen i algebra börja på nivå 1, vilket då blir lärarens uppgift att göra utan stöd av matematikboken. Förslag på arbetssätt för nivå 1 och 2 ingår..

Datoriseringen i samhället : Äldres upplevelser

As technology have continued to develop over the latest decades and become more advanced the pressure on the general citizens understanding of technology becomes a essential part to live in our society today.

The study has shown that after the older peoples time involved in the Agnes-project their quality of life had improved in different areas. Areas such as increased cognitive activity, increased interest in new technology and an improvement in their communication with friends and family.

Felansvar vid aktieköp. Kan felansvaret påverkas av en aktieposts storlek och säljarens totala innehav i bolaget?

This Master?s thesis aims to study how the concept ?youth? is understood and used in papers and publications about public libraries, written at The Swedish School of Library and Information Science from 1972 to 2002. It does this by answering three questions: Firstly, how is the concept ?youth? formulated in papers and publications at SSLIS from 1972 - 2002? Secondly, has the concept ?youth? changed in the analysed texts during the chosen time and, if that is the case, what constitutes this change? And, finally, what types of consequences for the understanding of the users can this have for the writers and readers of these texts? Discourse analysis is used to analyze how this concept is constituted, transformed and understood. Among the things studied in the discourse analysis is the interdiscursivity and intertextuality of the texts, as well as the meaning of the word, the wordings and modality of the analysed texts.

Åldern i fokus : En studie om hur svensk rätt påverkas av EG-rättens reglering av åldersdiskriminering i arbetslivet

Sweden is a member of the European Union (EU) since 1995. The association results in considerable proportions of the European law, also called EC-law, for Sweden. The legal system has precedence above Swedish law, which forces our national court to take consideration into and interpret the law in the light of EC-law.Sweden doesn?t possess a general legislation of discrimination. An appointed committee investigates the matter and the requirement of a common law, including all discrimination prohibits.

Flickor och pojkar i barnbokens värld: en studie om genus

The purpose with this qualitative text analysis was to study how the sex roles of children are presented in children's books published in 2004 in comparison with children's books published 1972-74. The focus was to find patterns and differences. The study embraces eight books intended for children aged 5-9.The main results of the study showed that the girls were described to have a greater bent to take care, while the boys in general were more aimed to perform and achieve. In both today's and the books from the 70´s, the boys were described as aggressive and independent and the girls were often looked upon as princesses by fathers and boys. Violent rowdy behaviour was the essential thing among boys in especially the books from the 70´s.

Twitter och nyhetsrapportering : En studie om Twitters roll för journalism och kommunikation

Since the emergence of social media websites as an established part of our society, the landscape ofcommunication has undergone dramatic changes. Especially in the field of journalism, the impact ofsocial media websites, such as Twitter, has been the subject of discussions about the actual partsocial media play in communication and news reporting. The general opinion has been that socialmedia has revolutionized the way we communicate and that a shift in power is taking place as themasses now engage in, and affect, our societies way of spreading information. This study is acritical discussion about whether Twitter in particular, and social media in general, has affected thejournalistic field in the extent that many claim it has. By comparing theories about traditionalmedia, such as television and newspapers, with recent studies about Twitter, we conclude that it isto early to establish the role of social media.
