Optioner är värdepapper som ger innehavaren rätten, men inte skyldigheten, att sälja eller att köpa den underliggande tillgången inom en given tidsram och till ett givet pris. Vanligen särskiljs det mellan aktieoptioner och indexoptioner. Fokus i uppsatsen ligger på OMXS30 indexoptioner från år 2006. Syftet med uppsatsen är att undersöka om den implicita volatiliteten enligt Black-Scholes formeln bättre predikterar den framtida faktiska volatiliteten än den historiska volatiliteten. I tidigare studier, bland annat i en sammanfattande studie av Figlewski (1997), har resultaten varit tvetydiga.

AbstractThe aim of this study is to investigate how a picture book for children is transformed into an easy-to-read version for children who have just started reading. I examine two versions of Emil of Lönneberga. One of the books is the orginal picture book of Emil in Lönneberga and was written by Astrid Lindgren (1963), while the other is an easy-toreadversion of the book, as adapted by the author Helena Renvall (1977). I have conducted a comparative study as a text and picture analysis of the material, with the focus on the adaptation of the original story. The adaptation in this case is a revision intended to make the story easier to read and more accessible to today?s children.

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

Optionshandeln har ökat markant på senare år och detta beror på att investerare vill sprida sina risker. Är optionerna korrekt prissatta eller kan det finnas arbitragemöjligheter? De flesta av investerarna använder sig idag av Black & Scholes formel då de prissätter optioner. I Black & Scholes formel är volatiliteten för aktien okänd och måste uppskattas. I denna uppsats vill jag undersöka om likviditeten har någon effekt vid uppskattning av volatiliteten.

I uppsatsen jämförs William Paleys Natural Theology : or, evidence of the Existence and Attributes of the Deity, collected from the appearances of nature från 1802 med Michale J. Behes Darwin's black box : The biochemical challenge to evolution från 1996. Jämförelsen kontextualiseras med en skiss över evolutionsteorimotståndets historia under den mellanliggande perioden, som tillsammans med själva den vetenskapliga utvecklingen, antas förklara de skillnader i tilltal och val av argument som föreligger mellan de två verken. I fråga om grundläggande budskap, idéstruktur, syfte och religiositet befinns de två verken ligga varandra betydligt  närmare än vad som initialt kan tyckas vara fallet..

The purpose of this essay is to study the film culture in South Africa in a national cinema-context, focusing on the relationship between anti-apartheid film from 1974-1994 and the film in South Africa today. By pitching the South Africa-specific works of Lucia Saks and Jacqueline Maingard against the over-arching debate on national cinema as formulated by, amongst others, Stephen Crofts and Andrew Higson, this study aims to find whether or not a specific South African national cinema have existed, and exists today, or not. The study finds that an underground culture of documentaries and short films made by and for the black population has been in place since the apartheid, and the distribution method on video and television is still being used to reach the black population today. By re-examining the concepts of both the national, and of national cinema to also include film on video and television, the study shows that South Africa has indeed a film culture that can be called a national cinema..

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

Business incubation is an important force of economic development but relatively unheard of in organization theory. This is partly due to the fact that in organization theory, meta-organization or the organization of organizations has been neglected or left lagging as much theorization has been focused on organizing individuals. With the growing number of business incubators, and meta-organizations in general, the need for understanding a relatively new type of organization is prevalent.This case study of the business incubator Global Business Labs Botswana (GBL) aims to clarify the organizational differences among meta-organizations and traditional organizations on a case level, as well as explain the underlying factors for these dissimilarities. With respect to the nature of this case study no general conclusions are drawn from the results. The inference, however, is that the organization of GBL and its incubated companies differs from the traditional organization in five elementary aspects: the weak hierarchical structure, the operational autonomy of its members, the strong focus on recruitment processes, the member identity and the lack of formal sanctions.

As birch is one of the most common trees in Sweden, and probably one of the easiest for someone who lives here to identify, it is interesting to note that most people do not know how variable the genus is and how widely it is distributed across the northern hemisphere. One can find birch growing at both high and low elevations, demanding different soil conditions and preferring varying amounts of sunlight. Many people may also be surprised to hear that the colour of the bark can vary from bight white to almost black, and different shades of pink, orange and red can also be displayed. This, together with the astonishing beauty of the genus, the important role as a pioneer in many ecological systems and the difficulty in sorting out the taxonomy of the genus, constitutes the background of this thesis. The thesis is written at the Department of Landscape Development in Alnarp, Sweden with Kenneth Lorentzon, researcher at the Swedish University of Agriculture as a supervisor. The aim of this thesis is to highlight which species and cultivars within the genus Betula could be appropriate for horticultural use in Sweden.

Syftet med denna uppsats är att svara på frågan hur läsare och media reagerade på bloggen Black Ascot i egenskap av en litterär bluff, även kallad en litterär fabrikation. Målet är även att komma fram till hur mottagare av textbaserad kommunikation reagerar på att bli lurade. För att uppnå syftet undersöks läsarnas och medias reception av Black Ascot. Uppsatsen diskuterar även om det finns förklaringar till receptionen i bloggens litterära utformning. I analyserna framkommer det att diskussioner gällande framförallt autenticitet och moral uppstod såväl i media som bland läsarkommentarerna. Trots att negativa reaktioner förekommer i båda undersökningsgrupperna tyder resultatet på att en majoritet av bloggläsarna uppskattade bloggen även som en litterär fabrikation.

The purpose of my essay is to analyse the antiziganism imparted by the Swedish Governement during the 1930´s and 1940´s. The starting points are the text in the first published chapter of the Governement´s White Paper and other political texts refered to concerning surveys of the gypsies. My sources will be these texts important for the time period of my essay. The White Paper recites in chronological order for the repeatedly made surveys and registrations of the gypsies made by the authorities during the 1900´s. My analysis will apply the theories of Michel Foucault being about biopower/biopolitics and the method for ideological analysis by Sven-Eric Liedman.

Malignant melanoma represents 4-7% of all canine neoplasms and they are the most common malignant tumors of the oral cavity and digits. These tumors are often aggressive and metastasize quickly. To date there is no effective treatment and survival times are short. Most dogs are euthanized due to complications caused by metastases. Melanin pigment is a hallmark of melanomas and is usually present in large amounts in these tumors.

Många elever ser naturvetenskapliga ämnen som svåra och tappar lätt intresset om inte läraren presenterar ämnet tillfredsställande. Jean Piaget har haft stor betydelse inom pedagogiken, då han menade att intelligens är en metod som barn kan lära sig genom att utforska och laborera. Genom möjligheten att få göra en observationsstudie på höns kom tanken att omarbeta denna till ett etologiprojekt för biologiämnet på gymnasiet. Projektet innebär att eleverna får arbeta med en observationsstudie från grunden, och goda möjligheter finns att integrera andra ämnen i detta. Människan började domesticera höns för tusentals år sedan, en process där djur utvecklar ett adaptivt beteende till människan och dess miljö.

This paper investigates the representations of Africans in the Swedish comic press around the time 1880-1920, with the purpose of establishing how Africans were depicted and how these representations can be explained. The sources consist of four comic magazines: Kasper, Söndags-Nisse, Strix and Naggen.Results show that images of Africans in the late 19th and early 20th century Swedish comic press highly conform to international representations. Traditional stereotypes and overall caricatures are widely applied, mediating racial difference and black subordination. The comic strips and jokes can be divided into categories, defined by their main theme: 1) Exotic animals and nature 2) Skin colour 3) The unintelligent or uncivilised savage 4) Cannibalism 5) The civilised African 6) Imperialistic overtones. The use of international stereotypes indicates that some comic strips might have been directly copied from foreign publications, and incorporated into Swedish contexts.Several theories, likely interacting, can be considered in explaining the imagery.
