Styrelsesammansättning och lönsamhet i svenska aktiebolag

In this thesis we examine the relationship between board composition and firm performance in Swedish companies. The selection of companies includes all Swedish limited liability companies, with the exception of micro enterprises, that have been active between the years of 2009-2010. We develop hypotheses based on resource dependence theory, agency theory, and the resource based view, and test these with regression analysis against collected data. Specifically, we examine the effects of board diversity, outside directorships, and CEO duality. Our findings show that none of the theories provide sufficient explanatory power of the relationship between board composition and firm performance, and that further research is required to better understand the role and effects of company boards..

Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips

Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of stump are probably of great importance to make it accepted as fuel. It is therefore rewarding to carry out an investigation in this area for stump. This report represents results from a diploma project, which was aimed to develop a fixed bed reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic modelling employing Ozawa method and different kinetic models including one-step and three-pseudo-component models.

Teoretiska perspektiv på musik och insomning - En musikvetenskaplig litteraturstudie om möjliga förklarings- och förståelsemodeller

This essay constitutes a literary study investigating how scientific literature within thefield of musicology can benefit to the understanding of how people use music as anaid for sleep and relaxation. Furthermore it aims to answer the question of whatconclusions can be drawn about the music people choose to use in these types ofsituations. The essay depicts the phenomenon of sleep music from several anglesgathered from the literature and investigates several models of understanding howand why people use music as a tool for emotional influence. As a complement to this,and to illustrate the modern usage of music for mind-altering purposes, the essay alsostudies a selection of digital sleeping aids ? apps.The study shows a complexity since the phenomenon can be viewed from severalangles that are not always consistent with each other.

Barns kulturskapande : En etnografisk studie om förskolebarns interaktion

AbstractThe aim of the research presented in this thesis is to study how interactional strategies are used by children and what these strategies mean or imply in the preschool cultural context. The theoretical point of departure in the study is the socio-cultural perspective (William Corsaro, Roger Säljö, Jim Wertsch). The study is a contribution to the field of research that focuses upon contextual issues and an overall way of seeing the child. This is in opposition to the strong traditional psychological perspective in the development of the child, where a focus upon the individual dominates in special education. This ethnographic study aims to answer the following research questions; What interactional strategies are co-constructed by the children in preschool play? How do the interactional strategies influence the creation of culture in preschool play? The children, 3-5 years olds, and their play situation were in focus.

Den europeiska identiteten : Komparativ studie mellan kommissionsordförande Barrosos syn på Europeisk identitet och EG/EU:s tidigare officiella hållning

What is the European Union (EU) and which countries should be part of it in the future? These questions became topical during the first part of the 21st century when political and geographical changes hasten the need to decide the nature of the European cooperation. In the European Constitution, that never come into force, the European values that a key role but was taken away in the succeeding Lisbon Treaty. Nevertheless EU continues to expand, recently to the East and non-European countries asTurkey are now on the ?waiting-list?.

En studie av två invänjnings-modeller i förskolan. :  3-dagars och två-veckors modellerna 

I have made a research about two different methods for introducing small children to Nursery School/Kindergarten. I choose to do this as I have found very little about this in the literature we have studied during my education to become a pre-school teacher.This period in the life of very small children and their parents is a big change in their daily life. The more traditional way to start pre-school is to do it very gradually during two weeks, the two-week method. This means that the parents visit the pre-school together with their child for a very short time, about one hour the first day. After one week they leave their child with the staff for about an hour and at the end of that week they try to leave it full time (6-8 hours).

Virtuellt ledarskap i näringslivet: Hur affärssimulering kan skapa kompetens, samsyn, och ökad ekonomisk förståelse i en organisation

The purpose of this thesis has been to explore the topic of business simulation from a theoretical foundation in social constructivism and theories concerning leadership as the management of meaning. The most important findings are that business simulation can be used for strategical leadership by management to create a common vision in the organisation members, which affects their perception of the business and the decisions and actions they make, which in turn can lead to a more efficient organisation that becomes better at meeting set goals. This can be viewed in different ways from different theoretical viewpoints: as inducing targeted changes in mental models to create changes in decision making and actions; as a secondary socialization process where the vision of management is externalized as a business simulation that is in turn internalized by the organisation members that participate in the business simulation, or as a way to frame and define the reality of the organisational members which creates a shared reference point against which a feeling of organisation and direction can emerge. In the future, business simulations may become increasingly used by organizations to create a common vision or to communicate a new decision to the organization members..

Kan konsumentförtroende användas för att prognostisera konsumtion i Sverige?

Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.

Olika modellering av vårdprocesser utifrån metaforiska perspektiv : ? Skapar det nya drivkrafter för processutveckling?

The study was conducted in Jönköping County Chamber of fibrillation and is about change and improvement of process modeling technology. The process for treating patients with fibrillation is in the need to evolve and improve. In order to develop the care they needed a current state description which usually is made with the traditional process modeling tool.Many scientists and health professionals is in the opinion that this technology gives a too rigid image to describe the care processes. It also does not sufficiently take into account the human aspects. This reasoning suggests that the process modeling technology in healthcare is in the need to develop multiple perspectives.

Affärsmodeller och Strategier i Apples Appstore

Apple has since their launch of the Iphone series created a billion dollar business with the market place Appstore. Third-party apps have disrupted the mobile industry, attracted a high number of developers and set the standard for the industry. Despite success, this market has yet not been the topic of any academic study, a fact that makes this thesis important. Under the assumption that apps can be regarded as a service, traditional service marketing theories have been applied with the research goal to map existing business models, evaluate revenue potential and understand best practices of marketing techniques. A series of qualitative interviews with representatives from the difference business models, backed by secondary data describing the domain shows how the Appstore has evolved over time and which marketing practices that appear successful.

Omvärldsbevakning i Svenska Bankaktiebolag

The concepts of environmental scanning and Business Intelligence have gained increased interest over the last years in a number of different organisational contexts. The research in this field has mainly been dealing with methods and issues regarding organisation but the aim of environmental scanning, the forming of new perspectives, has been largely ignored. The purpose of this thesis is to study how Swedish joint-stock banks put environmental scanning and Business Intelligence into practice. First a literature study is made to create a background and to explain the different conceptions. Then I describe the different functions of the different services in Swedish joint-stock banks.

Pensionären och paddan : En studie av pensionärers upplevelser av läsplattor

Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.

Att ställa ut eller ställa till det: om utställningsverksamhet och tyst pedagogik på folkbiblioteket

The purpose of this master thesis is to investigate whether exhibitions and silent pedagogy can be used to develop more inspiring environments in the public library. Silent pedagogy is a term from the field of museum education describing the silent communication with visitors that takes place in exhibitions through introduction and orientation, layout and installation, as well as signage. In the 1980s, articles in a Swedish library magazine discussed the pedagogical importance of library exhibits and how they make the patrons aware of the library?s resources. This led us to museum education and a desire to investigate whether its theories were transferrable to the library context.
