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.

The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..

Introduction: Public health researchers have long been focusing on investigating health inpopulations through determinants such as income inequalities. Nevertheless, incomeinequalities can be considered an effect of the organization of welfare regimes. The publichealth status is largely affected by the organization of welfare regimes and consequently thereare large differences in health within and between welfare regimes. How are these differencesdistributed and how can they be explained?Aim: To compare health between welfare state regimes with the use of Esping-Andersen?swelfare regime typology and to investigate the relationship between welfare statedeterminants and health.Methods: A literary review based on 12 scientific articles.

The Swedish bank Handelsbanken has, according to their own way of measuring, been more successful than a weighted average of their competitors during the last 38 years. They have also handled the recent financial crisis, as well as the one in the 1990´s, better than most other banks. This paper studies their management control system at branch level in order to identify the controls which have been enforced to ensure that a low risk level is retained in the lending. The controls that have been identified are; (1) A decentralized organization with the offices as profit centers where the manager has restrictions regarding risk level and the results are measured as K/I (cost/revenue). (2) The absence of bonuses and individual follow-up regarding performance measurement.

Gränslöst arbete innebär att ansvaret ligger hos individen och denne själv kan bestämma var, hur och när arbetet ska utföras. Prestationsbaserad självkänsla bidrar till utmattning och sömnsvårigheter och att använda sig av kompensatoriska strategier är ett sätt att hantera gränslösheten. Syftet med studien var att undersöka sambanden mellan prestationsbaserad självkänsla, strategier och återhämtning bland personer med gränslöst arbete. En enkätundersökning genomfördes. Deltagare var 93 män och 47 kvinnor som arbetar på ett privat företag inom säkerhet och utbildning.

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Mergers and acquisitions are common phenomenon in today´s society in order to increase shareholder value. Two years ago a fusion of Sweden´s two largest companies in the industry of real estate took place and even though three out of four mergers and acquisitions financially fail this certain case turned out highly successful. The aim of this thesis is to examine how the organizational structure and the management control have been designed and characterized the organizational performance and furthermore what are the success factors of the integration. By studying an acquisition and its potential effects on organizational structure and management control parallel to a model that describes the best practice guidelines for managers to successfully deliver value from their acquisitions, it can be shown that an acquisition has direct effects both on the acquirer and the acquired company and thus the new organizational structure. The main results, thus, is that through active leadership, increased specialization, and more decentralized and thus efficient management control a new organization has emerged consisting of the best features of two separate worlds..

Syftet med uppsatsen har varit att synliggöra livsberättelsens och berättandets menings- och identitetsskapande kraft och funktion. Det är en metodologisk studie med strävan att fokusera på livsberättelse, både som fenomen och som social handling. För att göra detta har uppsatsen koncentrerats på min informants, Sveas, livshistoria.Narrativ metod, som legat till grund för studien, har varit av kvalitativ art i form av livsberättelseintervju i kombination med dialogisk-performance analysmodell med utgångspunkt i hermeneutiken.Som teoretisk referensram för arbetet ligger livsvärldbegreppet, social konstruktionism, livsberättelseperspektivet och minnets roll.En muntlig livsberättelse berättas alltid i enlighet med kulturella konventioner och i relation till olika diskurser och offentliga berättelser som dominerar det sociala och kulturella sammanhang som berättaren lever i..

Studien processinriktat och resultatinriktat motivationsklimat på svenska och spanska högstadieskolor undersöker skillnader och likheter inom processinriktat och resultatinriktat klimat. I denna studie undersöks det hur dessa två klimat ser ut på svenska och spanska skolor och detta ur svenska och spanska idrottslärares perspektiv. I studien används Nicholls (1989) teori om de två motivationsklimaten. Empirin är inhämtad via semistrukturerade intervjuer med idrottslärare på tre svenska och tre spanska högstadieskolor. Detta i kombination med Nicholls (1989) teori och andra modeller, ligger till grund för den senare gjorda analysen.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Telepresence production handlar om att kommunicera med video och audiobaserad teknologi i realtid över distans och att generera en känsla av närvaro fastän man fysiskt är på olika platser. Forskningsområdet är ett tvärvetenskapligt ämnesområde som innehåller datalogi, socialpsykologi, kognitiv psykologi och perception så väl som konst och storytelling. Den här uppsatsen behandlar främst den process som utformning av ett videomedierat möte innebär. Det finns olika variabler som sägs påverkar upplevd närvaro, men då människors upplevelser är subjektiva är det en stor utmaning att söka generella slutsatser. Uppsatsen är avgränsat till att endast behandla yttre faktorer.

The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.

Problem formulation? Are there any factors affecting the choice of marketing strategy?? What is it that determines the degree for the company to use a standardized or a adapt marketing strategy?? How profitable is Scania's marketing strategy in each country?Objective: The overall aim of this study is based on local adaptation and global standardization to compare the degree to which the company Scania chooses to adapt or standardize its marketing to the South American and Asian markets.We also aim to compare and describe any factors that affect the countries' differences in marketing strategies and to evaluate and measure the profitability of marketing strategies in each market.Methodology: The study is limited to Scania's marketing in the truck market in Argentina, Brazil, Malaysia and Singapore from 2006 to 2010. In order to answer the study's problem formulation and purpose we have chosen to combine a qualitative and quantitative approach. Four interviews were conducted with marketing executives from Argentina, Brazil, Malaysia / Singapore and Sweden. We have also chosen to examine Scania's annual report and include figures on the market shares of Scania in the respective countries and the number of sold Scania truck which is then compared against the number of registered vehicles by country.

To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming interface (API) to be used when developing volume-rendering applications. A complete application programming interface has been designed. The interface is designed so that it makes writing application programs containing volume rendering fast and easy. The interface also makes created application programs hardware independent.
