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.

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 transition have affected our society in great ways and have made a great impact on different groups, one of them being the elderly population in our society. The purpose of this study is to examine how the fast technological development in the latest decades have affected the elderly in our society. This from their perspective by gathering empirical data through semi-structured interviews with elderly people involved in the Agnes-project, a research project focused on improving the general quality of life for older people and increase their knowledge about technology. 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.

The aim of this study was to analyze the assessment of the primary school, from the teacher?s perspective. There has been an ongoing discussion regarding assessment and about the purposes of assessment for a long time. But there is a paucity of research on what teachers believe about. This study examined primary teachers? beliefs on major purposes of assessment.Assessment is the process of gathering and interpreting information about students? learning.

This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.

The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

In this essay I analyze the way my collection of poetry relates to the concept cyclic. What is cyclic and what different interpretations are there concerning the concept? Which other related concepts are there regarding things that seem to reoccur regularly? How does the cyclical, the circular, relate to the linear in regard, for example, to the perception of time? Life often creates the sense that different phenomena and experiences repeat themselves. Different processes are conducted according to regular or irregular cyclical phases, situations seem familiar and events can be relived.         Starting from my writing project Sinnligt kviller, a collection of poems, I discuss these questions in themselves and the impact they have had on my collection. I describe the phenomenon cyclic as a result of the emotions and moods this term creates in a more or less decisive way.         The intention with this paper is to show how Sinnligt kviller offers different perspectives of and reflections upon the various feelings provoked by the cyclic in our lives, feelings that are given my own voice in the literary text under study..

The purpose of this study is to increase understanding of how nursing home staff at dementia care facilities interpret, treat and manages sexual behavior of patients. Four group interviews were made with a total of thirteen participants from three different dementia care facilities. The collected material was processed and thematized in pursuance of the research questions of the study. The results were analysed using three concepts from queer theory; heteronormativity, the heterosexual matrix and power, as well as an article about how nursing home staff constructs actions of patients. The results showed that staff member?s assessments about the patient?s sexual behaviours depended on their posture towards the norm of what is considered to be acceptable.

Syftet med denna studie var att beskriva betydelsen av studie- och yrkesvägledande aktiviteter med barn i åldrarna sju till tolv år. Kvalitativa intervjuer genomfördes med sex examinerade studie- och yrkesvägledare som bedriver studie- och yrkesvägledningsverksamhet med barn i grundskolans år 1-6 eller fungerar som stöd till pedagoger som arbetar med studie- och yrkesorienterande verksamhet med barn i dessa åldrar. Resultatet visade att intervjupersonerna anser att arbetet måste påbörjas tidigt, helst redan i grundskolans första år, för att målen så som de skrivs fram i de nationella styrdokumenten ska kunna uppnås. De förutsättningar intervjupersonerna menade krävs för att tidig vägledning ska kunna bedrivas är av såväl strukturell som av individuell art. Slutsatsen som drogs var att studie- och yrkesvägledande aktiviteter som påbörjas i grundskolans tidigare år och som följer elevernas kognitiva utveckling kan medverka till att eleverna ökar sina förutsättningar att göra väl underbyggda val i framtiden..

This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.

Detta examensarbete är ett försök i att utföra ett estetiskt projekt i ett språkämne nämligen franska. Jag genomförde detta projektet för att uppleva hur elever arbetar estetiskt i ett teoretiskt ämne. Eleverna skulle gruppvis utföra en tecknad serie och ett rollspel på franska, med utgångspunkt från den tecknade serien. Från empirin av mitt estetiska projekt med eleverna har jag analyserat hur eleverna upplevde projektet och därmed sitt lärande i ett teoretiskt ämne. Elevernas engagemang och motivation i arbetet var stort.

This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..

This scientific essay aims to more closely study how to best arrange a context that subtly conveys that change is possible in the treatment of patients who starve themselves. By describing a number of situations during the first weeks of a girl´s therapy, this essay focuses on some central themes in the initial stage. The essay is mainly aimed to explore the conditions for a meaningful communication with a patient who has a low BMI value and who quitted the nutrition-oriented care in her clinic. The essay is a form that allows for reflection on one´s own considerations about the wisest line of conduct in various situation. The work is based on an existential understanding of the starvation as a fragile person´s one and only way to reconcile with herself in the world that is hers.
