Studien har utförts på företaget Ericssons avdelning för strategiskt inköp och syftar till att utforma en inköpsportfölj som kan positionera maktbalansen mellan Ericsson och dess leverantörer. Undersökningen utförs på tre olika kategorier inom inköp; Hardware, Logistics och R&D Consultancy Services. Studien ger även förslag på strategier som kan appliceras för att flytta maktbalansen till en mer fördelaktig position. För att kunna utforma en maktpositioneringsmodell undersöker studiens författare vad som orsakar och kännetecknar makt i en kund- och leverantörsrelation, samt vilken påverkan de identifierade faktorerna tycks ha.Ericsson är ett globalt företag som är världsledande inom kommunikationsteknologi. Inköp av produkter och tjänster står för en ansenlig del av organisationens kostnader, varpå inköpsarbetet blir av stor betydelse.

Efficient numerical methods for option pricing is an active field of research. This project has the goal to examine possible ways to improve an established method of numerical pricing. The method is based on an adaptive finite difference method in price and uses the backwards differentiation formula of order 2, BDF2, in time. The project will focus on improvements to the time integration through implementation of discontinuous Galerkin methods, dG. Empirical convergence and accuracy results are obtained for equidistant dG-methods up to order 3 and performance is compared to BDF2.

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

This study gives voice to which strategies preschool teacher?s use they teach preschool children in different performance tasks. The overreaching aim of this study was to find out what teacher give expressions to, verbally and in action, and what educating strategy they use when the purpose is that the children are to learn something specific. The theoretical starting-point of the study is a phenomenography research which aims in finding and systematizing of forms of thought in terms of which people interpret significant aspects of reality. The study has a Sociocultural perspective which means that the structuring occurs through choice of which activities children have access to observe and engage in, as well as through in-person shared endeavours, including conversations, recounting of narratives, and engagement in routines and play.

The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media.

Hedemyr?s project has been about finding a meaningful position of utterance and a language for her practice. The general theme is performative art in public spaces.This text is a meta-narrative about this development and transformation process. It is also a proposal for choreographic practice as text, and thus a suggestion for what performative text could be.Her master project includes three intertwined parts. The foundation is an ongoing ?doing?.

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

This Master?s thesis examines different retrieval strategies used in cross-language information retrieval (CLIR). The aim was to investigate if there were any differences between baseline queries and translated queries in retrieval effectiveness; how the retrieval effectiveness was affected by query structuring and if the results differed between different languages. The languages used in this study were Swedish, English and Finnish. 30 topics from the TrecUta collection were translated into Swedish and Finnish.

Norske Skog Jämtland AB is like many other companies in a situation where it has to increase its purchases to provide its industries with raw material. To increase the available amount of raw materials, many companies employ purchasers to cover larger areas. This study aims to find out how to handle the increasing competition for timber suppliers. An important input for defining such a strategy is to examine how the suppliers view their relation to the company today. For a company it is extremely important to have a good relation with the suppliers to secure long term supplies.

Among the studied methods are Harris index and Stattin´s oscillation index.

SAMMANFATTNINGTitel: Belöningssystem - hjälpande eller stjälpande? En fallstudie om karriärreformen förstelärare på en gymnasieskola i Gävle.Nivå: C-uppsats i ämnet företagsekonomiFörfattare: Alice Viklund & Erika LundströmHandledare: Monika Wallmon & Lars EkstrandDatum: 2015 ? januariSyfte: Syftet med studien är att med avseende på prestation och motivation skapa förståelse för hur de anställda upplever implementeringen av performance management i form av monetära incitament.Metod: Syftet med uppsatsen var att skapa förståelse för det rådande belöningssystemet och studien har utförts genom en kvalitativ metod. Data har samlats in genom semistrukturerade intervjuer med tio lärare på en gymnasieskola i Gävle. Därefter har vi genom tematisk analys presenterat materialet och resultaten i en slutsats.Resultat & slutsats: Slutsatsen vi kom fram till i vår studie var att karriärsreformen på kort sikt har skapat en något försämrad kollegial atmosfär och en känsla av orättvisa. Detta tror vi är mycket på grund av att belöningssystemet fortfarande är i en initieringsfas och att dessa reaktioner kommer att avta.
