Return Behavior of Initial Public Offerings and Market Efficiency

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.

Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär

The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.

Patienters upplevelser i samband med en hjärttransplantation : en litteraturstudie

Background: In Sweden, heart transplantation increases as a method of treatment. Patients undergoing heart transplantation require special needs of care. Nurses have to increase knowledge about experiences that these patients percieve to conform the health care in the future. In this study, health science has been used as a theoretical frame of reference which includes a patient perspective.Aim: The aim of this study was to describe experiences among patients, elder than 18 years old, undergoing heart transplantation.Method: The method was a qualitative descriptive study with a context analysis based on ten scientific articles and an autobiography corresponding with the aim of the study.Results: The results of this study showed six themes about experiences that emerged among patients undergoing heart transplantation: feeling of vitality, existential crisis, importance of social support, destructive feelings, capacity of going on and the experience of quality of life.Conclusion: It?s not a guarantee that the quality of life will increase among patients undergoing heart transplantation and they need a specialist trained nurse available to support at all hours..

Framtida förändringar i det förebyggande diskrimineringsarbetet : Med utgångspunkt i gällande rätt

The purpose of this study is to investigate the reading methods that pedagogues, active in classes 1-3, use in the first stage of learning to read and how they consider their own choices of methods. In the theoretical background I sort out the basic differences between synthetic and analytic methods of acquiring the skills of reading. The analytic reading method means that the skills of reading starts with the complete text in order to later analyze the parts of the text. The synthetic method approach is based on a reading method where the parts are linked as a whole. The two methods are considered antipodes but can also be looked upon as complements in the current governing documents.

Betongpelare och brand : En utvärdering av 500 °C isotermmetoden

At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

Geometri : Varierad undervisning i kreativ anda

The purpose of this study is to observe which method that is used when it comes to teaching geometry. The study aims to take a closer look at four different ways of teaching: illustrations, using practical objects, brainstorming and verbal communication. The method used to get the results is observation. With the result, we can deduce primarily that the educators make use of the four didactic methods to varying degrees. There are similarities between most of the teachers but also differences between them.

Ett säljsamtal via webbutik : Visma SPCS

The main objective of this thesis is to study how the structures of a sell dialog, via a web shop, should be designed in order to support and inspire the customer. To get the answer to this question I use a qualitative and quantitative method. The qualitative method is applied in connection with different interviews. The quantitative method is used to analyze different answers given from those who are interviewed. I also use the deductive method due to my interest of studying how reality can relate to the theories with the choice of the subject.Moreover, this thesis is structured by three main perspectives; company, customers and techniques.

Sesam, öppna dig! : rariteter i de svenska forskningsbibliotekens skattkammare

The essay deals with the patterns of storytelling in Selma Lagerlöfs novel "Körkarlen". The focus is on the relationship between idea and form. Selma Lagerlöf tries to show how the drinker David Holm comes to insight about his own shortcomings and faults without knowing that he is in fact educated by his old friend. The author of this essay tries to show that Selma Lagerlöf use the same method in relation to the reader of the novel. Selma Lagerlöf wants to enlighten the reader without actually preaching.

Hypotermibehandling efter hjärtstopp : Kognitiv och fysisk funktion samt självskattad hälsa efter 6 månader relaterat till tidsåtgång i vårdkedjan och primär hjärtrytm

AbstractAim of the study: Aim of the study was to investigate whether there were any connections in time between different parts of care in patients with cardiac arrest and hypothermia treatment and cognitive and physical function six months after cardiac arrest and to investigate neurological outcome related to primary registered cardiac arrest rhythm after six months and if there were any changes in cognitive and physical functions as well as self-related health between discharge from hospital and six months after cardiac arrest.Method: The study included 39 patients admitted to three Swedish hospitals between 2008-2011. Cognitive and physical function was evaluated with Cerebral Performance Cathegory, CPC completed with Mini Mental State Examination, MMSE for cognitive function and Bartels Index, BI for physical function and Euroqol-VAS for evaluating the self-related health.Result:  A significant connection was shown between time to start hypothermia treatment and BI, patients with longer time showed improved physical function after six months.Majority of the participants (66,7 %) had Ventricular fibrillation/Ventricular tachycardia, VF /VT, as primary registered cardiac arrest rhythm and in this group CPC and BI was significant better compared with the asystole /Pulsless Electrical Aktivity, PEA group.CPC, MMSE, BI and Euroqol-VAS were all improved over time.Conclusion: Participants with VF /VT as primary registered cardias arrest rhythm had significant better cognitive and physical function 6 months after hypothermia-treated cardiac arrest compared with participants with asystole/PEA as primary registered rhythm. This shows the importance of access to defibrillators in public places in the society and in hospitals and optimal education of lay people and medical staff. Cognitive and physical function and self-rated health improves over time, which might be a very important reason to convey patients, relatives and medical staff to continue cognitive and physical rehabilitation. Keywords: Cardiac arrest, hypothermia, cognitive and physical function, wellbeeing.

En Method Actors metod - Robert De Niros tillvägagångssätt med rollerna

Uppsatsen analyserar inledningsvis vad Method Acting innebär. Den ryske regissören och skådespelaren Konstantin Stanislavskij utarbetade i början på förra seklet ett system vars uppgift var att utforma ett skådespeleri som bröt mot normen av, vad han tyckte var, orealistiskt spel. Med naturalismen kom kravet att teaterns uppgift var inte att försköna verkligheten utan att visa verkligheten som den var. Stanislavskij besökte, tillsammans med the Moscow Art Theatre, USA i början på 1920-talet och presenterade sitt system för den amerikanska publiken. Några av hans lärljungar stannade kvar och började lära ut de nya skådespelarteknikerna.

En fundamental investeringsmodell : Portföljanalys på Stockholmsbörsen

I den här undersökningen har vi konstruerat en investeringsmodell, baserad enbart på finansiella nyckeltal. Modellen riktar sig mot privata aktiesparare då vi märkt att investeringsmodeller och andra existerande analysverktyg för aktiehandel är komplicerade och i regel avsedda för professionella aktörer.I modellen ingår fem nyckeltal som vi har valt utifrån tidigare forskning samt egna preferenser. Nyckeltalen har beräknats för 24 börsnoterade företag på Stockholmsbörsen 1991-12-31 - 1995-12-31. Syftet med investeringsmodellen är att bilda en aktieportfölj som vi prognostiserat ska ha genererat högre avkastning än jämförbara marknadsindex under perioden 1995-12-31 - 2009-12-31. Aktieportföljen inkluderat/exkluderar företag beroende av ifall de uppfyller investeringsmodellens nyckeltalsgränser.Resultatet av undersökningen visar att vår aktieportfölj var överlägsen markandsindex.

Finns det fler än en faktor som påverkar pribildningen av aktier - en studie inom den svenska aktiemarknaden

I denna uppsats undersöker jag huruvida CAPM eller APT modellerna ger resultat på den svenska aktiemarknaden mellan 1998 och 2007. Jag undersöker om någon av dessa modeller passar in i den svenska aktiemarknaden och hurdan är resultatet. Det som gör uppsatsen intressant är att jag använder båda modellerna i en och samma studie och jämför resultatet av uppskattningar av modellerna. Som markandsindex har jag använt OMXS30 index och som makroekonomiska variabler i APT-modellen har jag använt inflation, oljepris, industriproduktionsindex och ränta. Resultatet av studien är att med de makroekonomiska variablerna, som jag har använt, ger både CAPM och APT likvärdiga resultat.

Design och konstruktion av Splitmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

????Att lösa reglertekniska problem med Modelica

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
