Numerisk värdering av amerikanska optioner

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Mobil diabetesapplikation

This report is about the development of a prototype of a mobile application and a web application that will help diabetes patients in their own treatment and ease diabetes nurses work with their diabetes patients. The mobile application is a digital version of a diabetes diary used by the Örebro County Council primary care to ease in diabetes treatments. The report also covers tests with users which were conducted on potential users to get some sort of feedback from groups other than customer and colleagues. Tests with users showed that there was an interest in a mobile application and it was a highly appreciated project. The web application ease diabetes nurses in their work with their diabetes patients in the way that the web application can display graphs of the patient's blood glucose level. .

Den mångsidiga controllern och dess samverkan med den operativa nivån

Uppsatsen syftar till att undersöka hur controllerns roll ser ut i ett stort tjänsteföretag samt hur denna samverkar med chefer på den operativa nivån. Vidare studeras även vilket inflytande controllern har på den operativa nivåns arbete.  Studien bygger på intervjuer med controllern och ekonomidirektören på PayEx Solutions, ett företag som utvecklar elektroniska betalningslösningar. Därutöver har en enkätundersökning besvarats av chefer på den operativa nivån inom företaget.Controllerns uppgifter är inte väldefinierad i litteraturen och den har idag många olika arbetsuppgifter beroende på vilket företag som den är verksam i. De olika förväntningarna personer inom en organisation har på controllern påverkar också controllerns roll.

Betygsskillnader på Kallingeskolan : - ett attitydsproblem?

It?s not a new occurrence that girls have higher grades than boys. Statistics show the same at the Kallinge school in Ronneby. There is a great difference between boys and girls in their grades from the ninth class. There are many different factors that affect the pupils.

Miljöledningssystem vid Wilhelm Haglunds Gymnasium : Tillvägagångssätt för införande och certifiering

This report describes necessary steps for an implementation of an environmental managementsystem at a secondary school and what would hopefully lead to an environmentalcertification, using ISO14001 ? or as a possibility ? one of the so called environmentalawards. To the largest part, the descriptions and activities are general and can be used at anysecondary school at all, but the current status analysis ? with the started environmentalinvestigation ? and the environmental policy are directly coupled to Wilhelm HaglundsGymnasium. The document should work as a process support for implementation of anenvironmental management system at a secondary school..

Tro kan förflytta berg: En studie i hur gitarrpedagoger kan arbeta för att stärka sina elevers tilltro till den egna förmågan

Denna studie undersöker hur gitarrpedagoger kan arbeta för att stärka sina gitarrelevers tilltro till den egna förmågan att kunna spela gitarr. Jag har valt att använda mig av kvalitativa intervjuer som metod och jag har intervjuat både lärare och elever för att uppsatsen ska innehålla både ett lärar- och elevperspektiv. Jag har använt mig av ett antal begrepp som enligt Albert Bandura (1997) påverkar individens tilltro till den egna förmågan. Dessa begrepp är: Reflektion, Tidigare framgångar (Mastery Experience), Positiv feedback (Verbal Persuasion), Trygghet (Psychological and affective states) och (Bandura, 1997). Det framgår utifrån lärarinformanternas intervjuer att elevernas förmåga att reflektera, se att de har utvecklats och tryggheten på lektionerna är viktiga faktorer för att stärka elevernas tilltro.

Opera i Stockholm, Stadsgårdskajen

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Strategiska anpassningar vid nya h?llbarhetsdirektiv: CSRDs p?verkan p? f?retags strategiska beslut. En kvalitativ studie om hur f?retagsledningen inom textilbranschen anv?nder strategisk navigering och intern anpassning vid bem?tandet av ?kade krav p? h?

In a world characterized by increasing sustainability challenges, organizations are continuously facing new demands; creating new requirements of change management and incorporation of new strategic decisions. Today, organizations are responding to the emergence of new sustainability directives and regulations at a EU level, whence the latest sustainability framework CSRD (Corporate Sustainability Reporting Directive), becomes particularly relevant. Companies are therefore facing the challenge of integrating strategic management in their navigation, preparation and maneuvering of new directives; a transition that requires new strategic decisions and adaptations. The purpose of this study is to qualitatively examine how CSRD affects organizations in terms of corporate changes, operational adaptations and strategic decisions, as well as what capabilities are essential to incorporate. The study also aims to investigate relevant challenges and opportunities associated with the new directive.

Vision och Verklighet : I globala organisationer med fokus på operativa enheter

The purpose of this study is to contribute to a better understanding of how visions could be applied in subsidiaries and similar sub organisations of global enterprises. With increasing globalisation it becomes more difficult to work in accordance to same standards and towards a common and unifying interest. The study has a qualitative and deductive approach and is based on interviews with three global subsidiaries with some hundred people employed each.Conclusions are that the subsidiaries visions have to be based on a guiding philosophy issued by their mother entities and it is the responsibility of the sub organisation to develop a tangible image with a local vision, mission and strategy with targets requiring feedback. Sustainable strategies cannot be issued without a vision describing where the organisation want be in the future. Otherwise they will not come very far until they have to make a restart with a new strategy and they will never be a market leader..

Kvalitetsförbättringar och Emballageinstruktioner

This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.

Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Fallstudie: en analys av Kungens Kurva utifrån Huddinge kommuns vision för vidare utveckling av området

In this thesis, a case study of Kungens Kurva in Stockholm is made. The municipality of Huddinge has designated the area, which is an external shopping-center, as one of its key development areas in the future. The municipality has established a future vision for the area, which extends until 2030. The vision claims, inter alia, that Kungens Kurva along with Skärholmen will become a vibrant suburb. How well the values and aims of the vision are met in the current area situation is discussed in the case study by a number of analysis that carries out the existing structures and characters of the area.

Reklamen som inte får synas : En studie om produktplacering i TV-serien Solsidan

Tom Andersen (1995) utvecklade samtal där terapeut och klient tillsammans utvärderar samarbetet i terapin, samtal med reflekterande förhållningssätt som senare kom att kallas för samforskningssamtal. Samtal med ombytta roller, där terapeuten får lära av klienten. Studier har visat att samforskningssamtalen ger terapeutiska effekter med ökad känslan av samhörighet, fördjupad samskapande process och hjälper terapin framåt samt ger terapeuterna ökade kunskaper om sig själva som terapeut. Syftet med denna studie är att belysa om samforskningssamtal kan ge möjligheter och betydelse i pågående terapi och i så fall vilka.-Hur upplevdes samforskningssamtalet?-Vad fick terapeut respektive patient syn på i samforskningssamtalet?-Vilken betydelse kan samforskningssamtalet ha framöver i terapin? Två samforskningssamtal har hållits och därefter har en intervju hållits med var och en av deltagarna.
