In this thesis we study the development of post-earnings announcement drift (PEAD) in the Swedish equity market from 2000 to 2009. By forming portfolios based on the stock price reaction to quarterly reporting we show that the characteristics of PEAD have changed. We demonstrate that negatively surprising companies show a positive drift during a holding period of six months sufficiently large to render the trading strategy unprofitable. This development holds from 2005 and onwards and these results contradict many a study which finds the same portfolio construction to be indeed profitable. We argue that this development is a trend that will not only affect our study but future studies as well..

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

Aid effectiveness is a reoccuring theme in the social sciences. Maybe rightfully so, as development is slow in many parts of the developing world. Core literature on the matter seems to suggest that aid effectiveness is contingent on recipients? level of corruption. Assuming this to be true, I examine the EU?s disbursements of Official Development Assistance over the past decade by running regressions: is there a relationship between the level of aid received, and a country?s level of corruption? As the EU is one of the largest donors of foreign aid globally, and has the power to shape the global foreign aid agenda, this question puts to the test whether the EU is leading the way, or rather is an obstacle in front.

The purpose of this work is to develop and test a design process where quick decisions and model building has a prominent role. The goal is to develop a number of products and build prototypes to be shown during the Carl Malmsten Furniture Studies spring exhibition 2012. I?m also writing a report describing my work.To reach my goal I have each day during the first phase conducted a short research and found a concept based on that days name day. Then I have continued in the workshop and worked with three-dimensional models.

There is an ongoing process where the free market within the European Union is expanding, partly through the incorporation of new member states, partly through the signing of association agreements with nearby countries and regions. When trade barriers are removed in different ways more companies consider an internationalization of the company. However, the procedure of the internationalization of companies is a rather new and unexplored area in the context of research. The focus of this study is therefore to examine how a few companies situated in Sweden, has proceeded while searching for knowledge during the internationalization process. Data has been collected through interviews that have been balanced with information from Internet and other sources.

The study´s purpose is to investigate the underlying norms of how the concepts of language development and learning, used in the preschool curriculum. Knowledge of the concepts underlying norms can help to make visible what approach preschool teacher is expected to have to children's language, in relation to development and learning. The results of the study may in turn provide a picture of societal norms on children in preschool and a deeper understanding of the importance of preschool to review and analyze the content of the curriculum, then it is not a foregone conclusion.Theoretical basis is curriculum theory, which involves studying curricula in order to create a knowledge of a society and its cultural, social and economic demands. Norman Faircloughs critical discourse analysis is used as a method, in order to achieve the study´s intention and answer the questions at issues in the study. The critical discourse analysis considers that the discourse is creating the social world through language.The results of the study show that there is a language in the curriculum as normatively may influence preschool teacher.

The purpose of this thesis is to investigate the plaintiffs and the defendant?s prospects to change their claims and pleas in optional civil actions and how the rules for the modifications of a suit are affecting the framework of the process. The plaintiff's general ability to expand and alter the claim is found in the chapter 13, 3 § of the Act of Procedure and the basic principle is that a claim is not to be changed. From this basic principle exceptions are allowed to claim another fulfillment or to expand the process with a claim for interest or other additional obligations. The plaintiff can also limit his or her claim or expand the claim with new legal foundations as long as the issue of the process does not change.

Det finns ett behov av personer som klarar av att generera en mängd fräscha, slitstarka och kreativa idéer under press. Denna undersökning omfattar hur mångsidiga Art directors kan arbeta för att framställa och producera material som håller hög standard. Fyra Art directors har intervjuats och givit sin åsikt i ämnet. Utifrån resultaten av intervjuerna och en mängd kreativa tekniker har vi utfört en grundläggande idéprocess. Resultatet av denna process är en konstutställning där vi har skapat ett koncept med fokus på miljö och framtid.

The aim of this master thesis is to examine the attitudes among library staff regarding a music downloading service called Musikwebb, which is available in many Swedish public libraries. It focuses on the impact of Musikwebb on the process of music selection, the relationship between Musikwebb and the digital development in public libraries and what service Musikwebb offers its users. The gathering of material was executed through focus group interviews with library staff in four libraries. This empirical material we divided in three categories: Music selection, The Library and its digital services, and Library services. We use the results of Sanna Talja?s discourse analysis regarding the relationship between Music, Culture and the Library to analyze our material.

AbstractThis essay discusses the negotiation of the Comprehensive Test Ban Treaty (CTBT) and the process that led up to a signed agreement. The CTBT forbids all nuclear weapon test explosions and all other types of nuclear explosions. The purpose of the study was to distinguish the critical steps of the negotiations that resulted in the success of the CTBT. Based on these insights, my intention was to identify relevant events and actors in the process around the Fissile Material Cut-off Treaty (FMCT), which has been on the nuclear disarmament agenda for over a decade. Furthermore, my ambition was that the examination of the CTBT negotiation would give me some clarity in what the next step would be to get the FMCT back on track.

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

The purpose of this essay is to illustrate immigrants? and refugees? thoughts and experiences of the process of integrating into Swedish society and to examine which social networks foster the process. The main questions in the study are: * What experiences enable refugees and immigrants to become integrated and fully participating members of the Swedish society?* What is the importance of the social networks with regards to integration into Swedish society? A qualitative method was used and five interviews were completed with SFI (Swedish for immigrants) students. The study shows that knowledge of Swedish language promotes an initiative in contacting native Swedes, and it also determines the success of integration.

My thesis is a combination of theory and practice, where theory is meant to create a context and a background for my interpretation proposal. I wanted to ?access? the ideas that are always in the background of the reasoning which underlies both planning in a larger scale, and the design of a place. I wanted to make a ?work of ideas.? In the process of shaping the proposal, I wanted to be deleted from the site itself.

The ever-evolving information technology gives users more opportunities, but also put higher demands on them. The digital agenda of the state and society clarifies the objectives and effects academic libraries? development. E-books influence the development of organizational, economic, legal and political perspectives. At the University Library in Gävle work is ongoing. The process is controlled by the acquisition policy which makes it clear that e-books should be purchased if possible.
