Har analytikernas roll på aktiemarknaden blivit mindre relevant: En studie av analytikernas påverkan på aktiers avkastning

The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.

Bors E23 - Framtagning av eldriven röravklippningsmaskin

Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..

Studie i en studio - Undersökning av producenter och gitarristers syn på studioinspelning av elgitarr.

As I recently started to record in a studio, I almost immediately came to the conclusion that getting the right sound is not easy. I became curious about my recording procedure. What did I do wrong? How to place the microphone? Use of equipment? How is it possible to modify the sound afterwards? Are there any special methods that are commonly used among producers and/or guitarists? My thoughts ended up in a question ? What do producers and guitarists think of the guitar sound during a recording session in relation to the final production? In my research I interviewed two producers and two guitarists about guitar recordings. The results show that the quality of the guitar sound is in relation to production and style of music.

Mobilt slakteri för lamm

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

Från föreställningar till relevanta system - Linköpings universitetsbibliotek analyseras med hjälp av Soft Systems Methodology

The background to this thesis is the impact of information technology on libraries and librarywork. If information technology causes changes in the tasks and work of libraries, thenlibrary organisations should also change. It is important to engage and inform the staff if suchchanges are to succeed. This thesis investigates the notions about library tasks and librarywork among eight "middle-managers" at Linkopings universitetsbibliotek.The investigation is based on interviews and then analysed with Soft Systems Methodology(SSM). By identifying the "Weltanschauung" of the staff, the thesis tries to create logicallydesirable and culturally feasible models of systems relevant to the situation at Linkopingsuniversitetsbibliotek.

Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm

When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

Fysisk aktivitet på recept : En kvalitativ studie ur ett patientperspektiv

BACKGROUND: Exercise on Prescription (EoP) means that a doctor writes out a customized form of exercise to the patient instead of medicine, or in combination with medication. The activity becomes a part of the treatment. Since many today do not follow recommendations for physical activity occurs in the long term a number of public health diseases. EoP promotes health and prevents disease. AIM: The aim of this paper is toexamine whether EoP from a patient perspective perceived to be an efficient and effective method of treatment.

Energianvändning i badhus : Simulering och jämförelse av gamla och nya system

Every year new premises are built in Sweden, and even if they are made as energy efficient as possible, this will not reduce the energy demands, but the rate of the increase of the energy use will be reduced. One type of facility in Sweden that is a major energy user is public baths, and this makes public baths an interesting facility to study more closely. There are around 500 public baths in Sweden and about 75 % of those can be seen as older baths with large need of renovation, and they all require a high level of energy efficiency measures. To show how the energy demand increase or decrease depending on the changes chosen to be made, the simulation application IDA Indoor Climate and Energy was used. Simulations were made and compared for several cases, with two extreme cases as starting points.

Energieffektivisering av arbetsbodar på byggarbetsplatser

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.

Lära matematiska begrepp på sitt andraspråk : Matematikspråket - vardagsspråket

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

Lysande rör, rörligt ideal : belysningsbranschens introducerande av lysröret i Sverige

During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g.

Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning

Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition. This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking. The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.

Både chef och bibliotekarie: om chefsrollen på folkbibliotek

The majority of managers of public libraries in Sweden also work as librarians on an operative level within the organisation. This thesis discusses how the manager role is affected by his/her specific assignments and multiple tasks. Seven public library managers, who work in districts with around 10 000 25 000 inhabitants, have been interviewed. They reflect upon their experience of leadership and different assignments. The main focus lies on: - leadership - communication - decision making - organisational development The interviews show some positive effects, the manager is present most of the time, has a great knowledge about everyday work and daily routines, and is also able to represent the library successfully in the local community.
