Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.

A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.

Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler

This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.

En diskursreglerad v?rld: Makt, kunskap och agens i Mark Lawrence? The Book That Wouldn?t Burn

Historically the library has owned more than silent, book-filled halls; it has been a center for learning and ideas, a source of both freedom and oppression, in other words, a medium for knowledge, truth, and power. Cultures have been divided into powerful and powerless through access to the library's content; those who have - and those who do not have - access to information determine which voices are heard and which are ignored, thus determining the outcome of the future. This thesis investigates how The Book That Wouldn't Burn by Mark Lawrence portrays the relationship between knowledge and power using Michel Foucault's discourse theory. More specifically, how this relationship is manifested through the structures and norms of society, and how the library as a place and institution serves as the means by which this relationship plays out. An established classic like Fahrenheit 451 by Ray Bradbury is placed as a contrasting reference point to help deepen its thematic message of information control and cencurship. Furthermore, the agency of one of the main characters is also examined in the light of Anthony Giddens' stratification model, as an actor with the potential to move beyond the confines of the power structure. The analysis demonstrate how knowledge, truth, and power remain continuously thematically relevant within literature, and how the reality of our time may be better understood through literary contributions.

Vikten av användarvänlighet : Quality of Experience som metod för utvärdering av en mobil applikation

Det här är en litteraturstudie som undersöker hur forskningsfältet kring utomhusmatematik ser ut, samt de olika resultat som forskningen kommit fram till.Genom systematiska sökningar har tretton artiklar i sin helhet valts ut för granskning, samt nio artiklar som ej finns tillgängliga i fulltext. Dessa inkluderades för att bidra till en mer komplett beskrivning av karaktären för hela det aktuella forskningsfältet. Resultatet visar framför allt att det finns relativt lite forskning inom området. Endast fem artiklar kunde bedömmas uppfylla kriterierna som vetenskapliga och därmed får dessa stå till grund för att visa vad forskningen för området säger. Dessa artiklar konkluderade att elever spontant upplever utomhusmatematik som roligt, att de lär sig lättare samt får en djupare förståelse för matematiken.

Utomhuspedagogik : Hur pedagoger arbetar med naturvetenskap utomhus

The aim of this study is to understand which strategies helped women escape honourbased violence, by reading the autobiographies of seven women. Honourbased violence is a relatively new problem in Sweden, but it has existed for a long time. According to FN (2012) 5000 women are murdered every year in the name of honour. Honourbased violence is about maintaining the honour of the family. Womens sexuality is connected to men´s honour, and because of that they are not allowed to express it.

Konsten att mäta tjänstekvalitet : En utvärdering av tre instrument för att mäta tjänstekvalitet i kollektivtrafiken

The purpose of this study is to analyze and evaluate the suitability of the three instruments SERVQUAL, SERVPERF and Zone of tolerance to measure service quality, from the respondents' perspective. This study has been carried out by a quantitative method in which respondents answered three questionnaires, which was based on the three instruments. The SERVQUAL instrument is a revised version based on criticism by Carman (1990). It is based on the five dimensions; reliability, responsiveness, assurance, empathy and tangibility, with 22 items in which each dimension is associated with a number of items. SERVPERF is the instrument most similar to SERVQUAL and is also composed of the same five dimensions.

ScenÖsterlen. Kulturprojekt för barn och ungdomar - betydelsefullt i en mindre kommun?

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Analys av artificiella marktyper vid vatten med hjälp av GIS, Värmlands län 2007

On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).

Djurägares syn på cytostatikabehandling av hund : en enkätundersökning

Chemotherapy is one of the most important methods of treatment available today for the treatment of neoplastic diseases and gives many patients an increased quality of life and a prolonged survival time (McKnight, 2003). The object of this study was to find out more about owners? views on and experiences of chemotherapy of dogs when it comes to for example quality of life, side effects and if they would make the same decision and treats their dog again in the future. A questionnaire was in the spring of 2009 sent out to the owners of 100 dogs that had been treated with chemotherapy for neoplastic diseases at Universitetsdjursjukhuset, Sveriges Lantbruksuniversitet (SLU) in Uppsala between 2002 and 2008. The response rate was 67 %.

Distansskogsägares nöjdhet med Södras tjänsteutbud och kvalité på tjänster

The development of technology and the mechanization in the Swedish forestry has during the last 60 years resulted in depopulation of the country side and due to that the amount of distance forest owners has increased. Therefore the forest companies need to make some adjustments in order to keep the distance forest owners as customers and to attract new ones. The purpose of this essay was to examine and analyze the distance forest owners satisfaction with Södras service offering and quality of service and further develop some proposals for action. A web-based survey was sent out to 634 distance forests owners in Stockholm, Sweden, all members of Södra. 269 respondents participated in the survey and of them, 27 did also participate in a follow-up telephone interview.

Våra sociala medvetanden: En diskussion om ett socialt perpektiv angående medvetandet

In this essay a social perspective on the mind is explored and argued for. The essay moves from a discussion of a social collective foundation for the individual mind to a discussion ofthe main alternative ways of describing the shared social world, namely an action-centred perspective and a power-centred perspective. It is shown that these two perspectives are combinable. A combination of the two perspectives is therefore recommended for a more balanced way of describing the shared social world. In this essay it is argued for that the individuals? mind and her identity is dependent on the surrounding community.

Kilhus i plast : Omläggning av stålprodukt till produkt i plast

AbstractOur bachelor degree thesis was carried out in collaboration with Ivar Petterssons Järnmanufaktur AB in Smålandsstenar. We were asked to replace their wedge housing, used to fasten the wires to the power lines, with a similar structure in a plastic material. The idea for this project started with Ivar Petterssons Järnmanufaktur AB having problems with the casting quality that forced them to perform expensive tests on each of the wedge houses to ensure the quality. They are currently produced in China which is also a major drawback because it requires expensive long delivery times.The method we used is Fredy Olsson's Princip- and Primärkonstuktion (1995). We have consistently been in the project on so-called "broad front", which means that you create several sketches, ideas and changes in parallel, and then evaluates all.

Utformning av förskolans inomhusmiljö utifrån ett genuspersketiv.

The purpose of this thesis was to examine the ways in which the constructions of heterosexuality and gender in three Disney movies about princesses affect the power relations between men and women in the movies, and how discourses on gender and heterosexuality have changed over time. Research questions were:How do characters in the movies talk about gender and heterosexuality?How does the interplay between gender and heterosexuality affect the power relations between men and women in the movies?What are the likenesses and differences between movies from different time periods?Discourses were mapped out using a model based on Ernesto Laclau and Chantal Mouffe?s political theories. These discourses were then analyzed with a theoretical framework consisting of Yvonne Hirdman?s concept of gender system and gender contracts, Judith Butler?s view on the heterosexual matrix and an understanding of power relations based on Michel Foucault.

Statistisk behandlig av driftsdata : Ur Garpenberggruvans driftcentral

Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.

Analys av användning av Intelligent Power Modules för motorstyrning

Det här arbetet utfördes på ABB Corporate Research, och innefattar en studie av motorstyrning i allmänhet, och hur man med hjälp av en Intelligent Power Module kan effektivisera motorstyrning genom att ersätta separata kraft- och styrmoduler med en kombinerad modul. En IPM från International Rectifier har modifierats och testats genom att under en längre tid låta den styra en permanentmagnetmotor under normala förhållanden. Resultatet från testkörningen visar att en IPM är ett bra alternativ i framtiden, såväl i fråga om effektivitet, som kostnad och utrymme. Efter en undersökning av marknaden visar det sig att det är långt ifrån säkert att modulen från International Rectifier är den bästa som finns att tillgå, och det skulle förmodligen löna sig att testköra IPM:er av andra tillverkare i mån av tid och pengar..
