This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.

The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.

The purpose of this study is to show how the modern society, with demands, expectations and the time constraints of adults, affects children and the everyday life at the preschool. Our intention is also to show the importance of identify stress symptoms of the children.        The study is of qualitative empirical kind and is based on a questionnaire to 19 parents of preschool children at the age of three to five years old. Interviews are made with four preschool teachers on one preschool. An observation of children in possible stressful situations is made during three days each at two preschools.     The results show that the modern society affects children and can be stressful. It also affects the everyday life at the preschool.

A uniform environmental rating system for green buildings is demanded in today's society, where the requirements of the energy consumption for real estate are increasing. There are several different systems around the world used to rate buildings, all with different assessment criteria and starting points, which make it difficult to compare environmental rated buildings with each other.The purpose of this paper is to acquire knowledge about the differences between the Swedish environmental rating system Miljöklassad Byggnad and the American LEED, to discover which system is most advantageous. We also examine whether environmental rating affect the value of a property.Miljöklassad Byggnad is relatively simple structured, which makes it possible for private individuals to rate their property. LEED is better structured on the other hand in the case of environmental classification of commercial properties, because there are manuals for among others hospitals, schools and retail. The rating system for Miljöklassad Byggnad is good since the system seeks to fix the number of errors and deficiencies as soon as possible.

Background: The real estate market has previously been subsidized by the government. The construction has been characterized by standardization and large scale complex. In the current situation there are other conditions on the real estate market, subsidies do not occur at the same degree and the market is more competitive. Customer influence has also changed. Today the customers want to customize their apartment by personal needs and lifestyle.

The aim of this master thesis is to describe some general trends and important steps in the Swedish university libraries user-orientation from the implementation of the university college reform 1977 until today. The aim gave rise to four further questions. Literature studies and empirical studies in the form of focusing interviews have been carried out, in order to answer the questions. Of the entire background material I have made a simple form of general analysis. I found that the libraries, during the years have interacted with the following four interested parties, the government, the mother organization, other libraries and the library users.

Göbekli Tepe is an 11000 year old religious center where Totem has been exercised. It was raised by megalithic hunters and collectors that still during the construction lived in small-scaled mobile groups in order to find food and therefore should not have had time to raised costly stone monuments. The religious center consists of four enclosures with two T-pillars decorated with pictures of different animals and birds. Any dwellings have not been found. The place has been constructed by a well-organized elitist organization that has been capable of raising constructions in order to exercise their religion in a way we did not thought was possible such a long time ago. Analysis and findings from the near east existing from this time shows however that social changes happen in the communities around the region. Can archeological finding from the excavations on the religious center give any answer or clue regarding how man came to develop from hunter and collector to farmer? Do the findings reveal that the religion has changed Mans way to think and organize so that she was prepared to introduce the agriculture that occurs? The aim of thesis is to clarify whether Göbekli Tepe has played any role in the complex origin of agriculture..

Syfte: Gällande förvärv av kommunala hyresrätter har de flesta diskussioner som uppmärksammats, enligt vår uppfattning, rört ombild¬ningen från hyresrätt till bostadsrätt. Det är även det som teoretiskt finns beskrivet. Därför anser vi att vår studie kan bidra till att belysa fenomenet och öka vetskapen, om att hyres¬rätterna kan byta ägare och de facto byter ägare utan att upplåtelseformen ändras. Vårt syfte är därför att studera hur fastighetsköp gjorda av privata fastighets¬ägare från kommunala fastighetsföretag går till.Metod: Vi har i vår uppsats delat hermeneutikernas synsätt då vi är medvetna om att vår inställning och tolkning av studien kommer att påverka vårt resultat. Vidare har vi tillämpat ett kvalitativt tillvägagångssätt där vår studie grundar sig på intervjuer.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Turkey has taken part in regular negotiations to gain membership in the EU since 2005. At the same time is Turkey a candidate that stands out from those of earlier rounds of enlargement, and its possible membership got both supporters and critics amongst the Unions member countries. The aim of this thesis is to, trough a textual analysis, investigate the prospects and obstacles Turkeys candidature faces. The material consists of documents from a number of think tanks connected to the European Commission, as well as the Commissions own documents regarding Turkeys negotiations.A recurring picture is that Turkey is treated differently then earlier candidates, and that the Commission has a hard time keeping an unambiguous line in its negotiation frame. The material of the think tanks attributes the public opinions distrust of the member countries of EU as a hindrance, and Turkeys meddling in the conflict on Cyprus is problemized.

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

The purpose was to describe the significance of participation concerning leisure time and household duties for persons with mild intellectual disability living in a group home with some support from caretakers. Interviews were performed with five persons, two men and three women, living in such a group home. The questions in the interview guide had an open character and were divided into four different areas, leisure time, economy, cooking, cleaning and laundry. The results indicate that all informants felt they participated in all four areas. Further on, the results show there was participation of three different kinds.

Through a quantitative examination, 26 pedagogies in the pre-school activity answered a few questions in an enquiry about outdoor education. The purpose with this examination was to find out what pedagogies think and apprehend about outdoor education, and also if the "education plan" is in their minds during outdoor activities and if they see them self´s as competent in nature studies. They have also answered questions whether they think that they have good outdoor environment that stimulates children´s development and learning and if there´s any forest that they visit on regular basis.The pedagogies think that during time spent outdoor, it´s the motor skills that are best developed. All of the pedagogies mentioned above think that they need to get more educated in nature studies and also that pedagogies attitude towards time spent outdoors affect the children. They do not think about the goals and intentions of the "educations plan" all the time.

This study is about what teachers in primary schools say that they are doing to create a school for all.The purpose of this study is to find out what teachers in primary schools say that they do on their mission to create a school for everyone and how they organize teaching to achieve this. The study was conducted as an interview of five teachers from elementary school of different gender and with a qualitative method because it provides a great opportunity to problematize, interpret and understand the responses of the interviewees.The results show that all the teachers think that their mission is to teach so that they can give each student what they need to achieve the goals. This may not be every day but over time, they hope that all students feel that they get so much of the teacher's time that they need..
