This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.

Syftet med vår studie var att undersöka några lärares uppfattningar och erfarenheter av högläsning för eleverna, som pedagogiskt redskap. De frågeställningar vi utgick från var följande:I vilka sammanhang används högläsning?Vilka texter används för högläsning?Bearbetas gemensamma textupplevelser utifrån högläsning i syfte att utveckla läsförståelse och i sådana fall hur?Vi har använt en kvalitativ metod, där vi genomfört både observationer och intervjuer. Kvalitativ metod valdes eftersom vi ville studera och intervjua varje lärare utifrån sin miljö. Vi valde att använda oss av både observation och intervju eftersom vi ville skapa oss en fördjupad förståelse av hur lärarna arbetar med högläsning.

The purpose of this study is to carry out a follow-up study of the reading stimulating project Arts in Reading. The project was in progress between the years 2007 to 2009 in Sweden and nearly 80 librarians from 57 public libraries participated. The aim of the project was to initiate new methods fot how to stimulate reading for children. The promoters of the project wanted to initiate the use of new art forms in the work for reading promotion, encourage more collaboration with new actors in the culture area, and co-operate more with the children.The aim of the present study is to investigate to which extent Arts in Reading really succeeded in establishing its goals, whether new methods were brought about, and how this work was done. Another aim is to find out how librarians in public libraries work to develop children's reading.The theoretical framework is based on Ragnhild Söderbergh's term inculturation, Elisabeth Björklund's research on how children acquire literacy, and Lev S.

Intense competition among companies and luck or unavailability of certain resources in country of company?s origin force last to cross the borders, and start to hunt for new markets and cheaper inputs. However, by investing abroad the company is not only facing and dealing with cultural differences and new regulatory framework, but also becomes dependent on decisions and actions of different and to large extend unknown government. Moreover, the majority of the investments? flows are directed to developing countries, where power and capabilities of state authorities are considered to be more extensive than in countries of developed economies.

The purpose of my study is to investigate teacher?s perceptions of their mission in the preschool class, and how they work to promote children?s written language development. What methods and working methods they use to awaken curiosity and motivate children to read and write. I am using the qualitative research method to get answers to my questions. I have made four qualitative interviews with four teachers in preschool classes from different schools.My questions are:What conceptions does teachers have about their mission in a preschool class?What different methods and approaches does teachers use to stimulate and wake children?s curiosity for reading and writing development?The theoretical basis for my study is the socio-cultural perspective, where learning occurs in interaction.

In this degree project we wanted to investigate if there are any possibilities to get a higher income from grain growing by giving the grain to hens instead of selling it. We were also wondering if the manure has any value or if it only cost the egg producer money. If the egg producer cultivate his own grain and is able to store it in layer is there quite much money to earn. Expensive pasture makes it profitability to pay up to 1,35 Swedish crowns for a kilo of wheat. In our calculating we?ve used calculation from the company Lantmännen.

Goal: To describe which evaluation method is used by Swedish retailers to assess a potential retail location and to describe to what extent the retail brand effects this strategic decision. Design: Analysis of ten interviews with companies within five retail sectors in Sweden. Main study: Indication of what methods are used to evaluate a location and how a company's retail brand affects the decision. Results: Retailers use a mix of theoretical methods to evaluate the location attributes and possible profit. Most common among mixtures was an application of the analog method, residual method or the checklist method in combination with a financial assessment.

This paper examines what affects the demand for five Swedish ethical funds between the years 1997-2007. The purpose of this study is to examine if there is a relation between fund value and other values than just financial.

Syftet med denna studie är att undersöka och skapa förståelse för vilka framgångsdrivarna är för företagsekonomiska institutioner.För att kunna uppfylla syftet har vi tagit fram BEN-modellen. Modellen består av ett antal framgångsdrivare som kan leda till konkurrensfördelar samt bestående konkurrensfördelar för en företagsekonomisk institution. Dessa leder i sin tur till framgång, något som vi själva definierat med fyra olika mätbara variabler; söktryck, genomströmning av studenter, ställning i arbetslivet samt forskningsproduktivitet.Studien har genomförts på tre olika företagsekonomiska instituitioner där intervjuer och samtal genomförts med personer i ledande befattning på respektive institution. Som komplement till intervjuerna har empiriskt material insamlats i form av statistik för att kunna utröna hur framgångsrika de är enligt BEN-modellen.Studien visar att ambition och entreprenörsskap är två viktiga framgångsdrivare. Dessa två drivare kan en institution erhålla genom finansiella resurser.

In this work an assessment of the compressed air system in the facilities of Vattenfall Heat Uppsala has been conducted. The facilities constitutes, among others, a combined heat and power plant, and two waste incineration plants. The compressed air is supplied primarily by seven rotary screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of compressed air have been presented, resulting in decreased need of electric energy and reduced CO2-emissions.The results show that total need of electric energy in the compressors, during a standard production year, amounts to 5.83 GWh.
