E-books are not yet fully established on the Swedish book market. A frequently discussed theory is that this might be because of a loss in the reading experience. This thesis has the primary purpose to investigate whether the reading experience from E-books differs from the experience of reading a traditional book in paper. The book used for comparation is a poetry collection named Rakel delat med tio. I have designed the cover and the inlay of this book and as a part of the thesis the working progress is described.

The purpose of this empirical study was to investigate if stress exists among nurses, and if it exists how do they experience it and how do they cope whit it. The nurses also got to define the word stress. Karasek and Theorells demandcontrollmodell were used as a theoretical framework. The result of the study answers our research questions and gives us a good insight how the nurses experience stress and how they cope with it. The result shows that 56 of 60 nurses indicated that they experience medium to high level of stress a couple of days a week or more often and that it affects their work.

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

The main purpose of this study is to view the aims of the local authority of Botkyrka for their prehistoric village, and to compare those with the actual activities in the village.Because of no official formulated aims, the study were laboured through interviews, observations, analysis of evaluations and a parallell literature study.For the visiting pupils today, the village has an introduction, but not a follow-up. Pedagogically the follow-up is the most important part, seeing that it?s there the knowledge is created in relation to the experience.Through experience-pedagogy, based on learning by doing, try to attain an experience intended to generate knowledge. But in this case, the focus lands on doing, and the reflection fails to occur. This is a learning based on the situation, rather than on the reflection, situated learning..

In this study we have investigated how care users in a nursing home experience their possibilities for influence and treatment from the staff. The study was conducted through focus group interviews with six participants who we met on four occasions. Questions the study departs from are: How do users experience their opportunity to influence? How do the users experience the treatment from the staff? The study has a qualitative approach and has been analyzed by means of symbolic interactionism, with an emphasis on the Self. Our results demonstrate that in situations of good treatment there is also a good influence.

In a work environment where employees can be thrown into all sorts of situations and where anything can happen, it requires that they have good knowledge about what they do and constantly strive to improve their skills. The purpose of this paper is to study how professional police officers perceive learning in their work. Essay authors would like to find out how the police officers experience their formal learning, informal learning and police education. This is by research what the police officers learn through various forms of education and what they learn by practicing their profession. Previous research dealing with the subject and relevant theories are discussed and processed.

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.

We acknowledge the lack of empirical studies of the performance of analyst target prices in the Swedish stock market by examining the profitability of target prices for stocks publicly traded on the Stockholm Stock Exchange. We use consensus target prices issued between 2006-2010 and create two different strategies to observe the abnormal returns generated during this period. Going long in the top decile stocks with the best target prices and going short in the bottom decile stocks with the worst target prices generates a statistically significant abnormal buy-and-hold return of 8.9%. An active strategy with daily portfolio rebalancing and a timely response to target price changes generates a less significant monthly alpha of 1.4% against CAPM. The results show to be robust against the size effect discovered by Fama and French.

The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. It has earlier been thought that less tilling and higher water table levels would decrease the activity of soil microbes and thereby the decomposition, but recent experiments has showed that this has little or no effect. In this bachelor thesis a field experiment was made on drained peat soil with ley, outside Björklinge, Uppsala municipality, Sweden. The experiment was carried out in May 2011. The objective was to develop a method to examine how the net exchange of carbon diox-ide from plant covered peat soil is affected by temperature and photosynthetically active radiation (PAR).

It is important for every store to have a good financial performance which can be affected by the average purchase and the number of customers in the store. Customers shopping experience can affect both of these factors and therefore it is important for retailers to know about how an in-store environment can affect this experience. The purpose of this study is to give retailers an indication of the importance of consumers' shopping experience and how this may affect the store's financial performance. To study this subject an in-store survey was conducted in four grocery stores in Stockholm where a total of 320 consumers answered a total of 41 questions about their shopping experience. By sales data it was possible to conduct a statistical analysis to see which variables regarding consumers shopping experience influenced the average purchase.
