Riskkapital i svensk fotboll: En fallstudie om kontroll, tillit och förtroende

The aim of this paper is to examine how confidence in co-operative behaviour of partner is reached in a relationship between an entrepreneur and a venture capitalist. A case study has been conducted on a Swedish football club that has involved venture capital in order to develop the organization. The paper presents a theoretical approach which draws on a control model of interorganizational relationships developed by Dekker (2004) and a model developed by Shepherd & Zacharakis (2001) illustrating how control, trust and confidence is reached in a venture capitalist-entrepreneur relationship. The relationship between the football club and the venture capitalist can simultaneously be seen as an interorganizational relationship and a relationship between an entrepreneur and a venture capitalist. Because of the complexity of the relationship, different control problems prevail.

Att ösa ur ett hav : Om kunskapssyn och urvalsprocesser hos gymnasielärare i Samhällskunskap A

Teachers in social sciences have a broad subject field to base their education on. This term paper examines, thru interviews, which factors that have an influence on the subjects contents in the A course of Social Sciences at Swedish high schools. Having interviewed four active teachers at three different schools, it shows that control documents like subject- and national curricula have little to say about what kind of subject that should been taught. Teachers seem rather to rely on local collegiate consensus, the textbook, locally prepared control documents, and adjusting to program directions while choosing material. In the final discussion the risk of structuring the subject around the text book is being investigated, along the fact that new locally control documents need to be written even for basic planning structures.

Internetbaserade insamling och behandling av data

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

Aktiekursförändringar och sökfrekvens på internet

The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..

Att förena kontroll med rättigheter : En uppsats om barns rättigheter i relation till kontroll och regler i HVB-hem

This essay discusses children?s rights and control and system of rules in HVB-homes that provide treatment for adolescences with drug abuse prob­lems or criminal behavior. The results of this study are based on interviews with four persons working in managerial positions on different HVB-homes and shows the difficulties of having a children?s rights perspective in a con­text where a higher level of control is necessary to protect the best interest of the child. The study suggests that the question of balance between children?s right and the need for controlling system of rules needs to be fur­ther dis­cussed to improve, and as far as possible guarantee that these adoles­cence receive best possible care and do not suffer unfair restrictions on liber­ties..

Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

Mätsystem för effektförluster i en högfrekvenstransformator

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Arbetsmotivation i äldreomsorgen: en explorativ studie av uppfattningar hos medarbetare och chef vid ett äldreboende

An explorative study on the work motivation of employees at a retirement home. The three main factors are internal motivation, external motivation and control. A comparison between how important they estimate the different factors to be and how they experience them today reveals which factor is their key motivator and which areas that need improvement. Results indicat that internal and external motivation are slightly more important than control. And the amount of perceived control reflects the amount of creative and initiative behaviour of the individual.

Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.

Jämförelse av olika reglersystem för undervisningsändamål

Examensarbetet syftar till att jämföra nya alternativ till olika system för användning i laborationer i reglerteknikkurser för olika studentkategorier. Det skall utredas vilket av ett antal alternativ till mjukvaruplattformar som är bäst lämpat att användas vid reglerteknikundervisningen i ITN:s reglerlaboratorium vid Linköpings universitet. Tidigare laborationer i berörda kurser skall även modifieras så att dessa kan genomföras i de nya systemen.Examensarbetet resulterade i en rad modifierade laborationer och system att tillämpa i dessa. De nya systemen medför att all reglering sköts direkt från en dator istället för tidigare variant med externa apparater som programmeras. På så sätt kan större fokus läggas på regleringen i sig och inte de system som tillämpas för att utföra den..

Budgetstyrning och Balanserat styrkort : i form av en kombinationsmodell

Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.
