Vilka faktorer påverkar börsbolagens nedskrivningsbeslut?

By using univariate analysis, tobit and logit regressions, this thesis investigates determinants of asset writedowns. After controlling for variables indicating reductions in asset values, the results show that changes in senior management are significant in explaining the writedown decision and magnitude, which is in line with previous research. The explanatory power of changes in senior management has not increased with the transition to IFRS in 2005. No evidence is found supporting the hypothesis that the explanatory power of management incentives is higher for more discretionary types of asset writedowns..

Sjuksköterskors arbetsbelastning - en faktor för patientsäkerhet : En litteraturstudie.

Background: Every year, more than 1000 cases of adverse events are reported in the Swedish health care system. These adverse events cost approximately 240 million Swedish kronor each year. By explaining the factors that cause nurses to make mistakes when they have too great a workload, it is hoped the awareness of health care staff will increase. Aim: To perform a literature review which describes factors that can endanger patient safety when nurses experience too great a workload. Method: A systematic literature review encompassing both quantitative and qualitative material.

Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Styrketräning för truppgymnaster : mer än bara kroppsvikt som belastning?

Syfte och frågeställning: Syftet med denna studie är att undersöka de eventuella fördelar styrketräning med yttre belastning kan ge kvinnliga truppgymnaster på juniornivå. Frågeställningar: Vilken effekt på explosivitet i nedre extremitet har sex veckors powerträning med yttre belastning på truppgymnaster? Skiljer resultaten sig från de som uppnås vid traditionell gymnastisk styrketräning?Metod: Två lag som representerar Sverige-eliten på damsidan i juniorklassen delades in i test- (n=7) och kontrollgrupp (n=8). Testgruppen genomförde under sex veckor ett specialdesignat träningsprogram riktat mot power medan kontrollgruppen genomförde traditionell gymnastisk styrketräning. För- och eftertester genomfördes för att utvärdera effekterna av programmen.

Konstruktion av en autonom vindstation

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

Identitet i den somaliska diasporan : en intersektionell studie av kvinnors jag och delaktighet i samhället

This work applies intersectionality to five Somali women self-narratives and focuses on their identities and positions in Swedish society, but also their relation to Somali society. Since people constructs in relation to the environment, this work studies the impact of environmental confirmations of their own self. Intersectionality is brought into the social work with an operational attempt, and shows how critics of power and interplay between theories and empirics can provide new knowledge. Intersectionality also demands some alterations of the social constructionists? idea of the ego.

Ny teknik för småskalig kraftvärme : - med fokus på Organisk RankineCykel (ORC)

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

Företag i Mästarklass - En kvalitativ studie av MSAB, ASSA ABLOY, AAK och HEXPOL

This essay focus on three companies within the MSAB group. All companies have shown an incredible share price development since MSAB´s initial investment and ownership. The companies has been examined from the CEO´s perspective to map out similar factors of success. The aim of the study was to compare and see if the companies operate in line with Jim Collins (2001) study of how Great companies operate. The analysis show that, despite the young age of MSAB, ASSA ABLOY and AAK, they all fulfill Collins hard criterias for Great companies..

Ut ur hedersförtryck : En studie baserad på sju självbiografier skrivna av kvinnor som levt under hedersförtryck.

The aim of this study is to understand which strategies helped women escape honourbased violence, by reading the autobiographies of seven women. Honourbased violence is a relatively new problem in Sweden, but it has existed for a long time. According to FN (2012) 5000 women are murdered every year in the name of honour. Honourbased violence is about maintaining the honour of the family. Womens sexuality is connected to men´s honour, and because of that they are not allowed to express it.

Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Konstruera och rekonstruera traditionell kunskap - en diskursanalytisk studie av texter om internationellt utvecklingsarbete

The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.

Kunskap är som ballonger - den måste förankras om den inte ska försvinna bort : en studie av vad som påverkar en lärares val av undervisning

The purpose of this essay has been to identify a couple of different factors that matter when a teacher chooses method and raw material for teaching his students. The person interviewed is a man, whose lesson I also observed. The result shows that there are several factors of great importance for his choice. My conclusion of this is that this teacher?s choice depends on the school as institution with all the people that operate there, the composition of the students and the school?s curriculum, but this teacher?s pedagogical basic view also has a great importance for his teaching..

Micro-power wind energy convertors have recently increased in popularity. The reasons for this are among other things the increasing cost of electric energy and enviromental concern.In this thesis the connection of these micro-power wind energy convertors to the utility network is discussed. Electric standards for the connection of small production units is presented. Finally some calculations and measurements of electric quality are also presented. The utility network used in the calculations is part of Halmstad Energi och Miljö network..

Att återvinna det förgångna: en studie av exploateringsarkeologers informationsbeteenden

The thesis of this work has been to investigate the information behaviour of archaeologists. Interviews were made, between March-September 2002, with ten archaeologists, employed in one Swedish organisation, conducting rescue archaeology. The archaeologists were all experienced in working positions as project leaders. Our thesis could be expressed in following questions: - Which sources of information did the archaeologists use in their work? - Which external and internal factors had influence on the information behaviour? The results of this study have been analysed within a theoretical framework of T.D Wilson, Lars Seldén, Lars Höglund and Olle Persson, among others.
