The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

This paper includes astudy of the mutual fund market investors during a selected timeperiod. The reader is given a descriptive picture of how people in different age groups have  acted  in  conjunction  with  the  last  major  financial  crisis.  It  has  been  studied whether people in the different age categories have saved,purchased or sold during this time  period  based  on  theories  and  analytic  material  from  one  of  the  largest  fund operators in Sweden. The result enlightens people?s activity and risk appetite in relation to the fund market. The essay results in an explanation of the underlying cause of the behavior        of         the         people         in         the         different         age         categories.The paper assumes that the market is cyclical and that more crises will occur in the future.

The purpose of the study is to find out how some teachers in Kenya reason about children in need of special support. To undertake the study the following question are used:How do some teachers in Kenya reason about children in need of special support?The study has been made with qualitative interviews in Kenya. A total of four teachers at primary school level have been interviewed. The decision to do qualitative interviews is made by the opportunity to get as comprehensive answers as possible from the respondents' reason about children in need of special support.Three different kinds of special education perspectives have been used in this study.

Information overload occurs when the amount of information exceeds the individual s capacity to efficiently process and use the information available. In this situation information instead of being an asset becomes a load. This interview study deals with college students experiences of information overload when working on their thesis. Focus lies on use of Internet based information resources. The main result was that the students experienced information overload in specific situations and steps of the process.

How does a social welfare officer know when a parent with mental illness or behavioral symptoms is harmful to the children? As a social you are confronted with different ethical dilemmas on a daily basis. The social welfare officers have to follow their own authorities, laws, guidelines and regulations while at the same time do everything to satisfy their clients? needs. This inconsistency can sometimes be difficult to handle.

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

My point of origin concerning this thesis was an interest for how school may develop students? reading comprehension. International surveys show that the results for Swedish students? performance regarding reading comprehension have declined and the current curriculum, Lgr-11, emphasizes the importance of incorporating this into all school subjects. The special teacher education programme has raised the awareness concerning the importance of including the students and that learning is achieved in an interactive setting.

In all types of learning situations, it is important to find each student where they are at the moment in knowledge. I have reflections about  what animal experience students have with them when they begin their education. This thesis is about what home environment and in home environment acquried animal experience student at agricultural college have. This work is based on data collected through questionnaire survey done in two agricultural colleges in middle Sweden in the spring of 2007. Questions were divided into four blocks, historical data such as on the environment in which pupils are growing up, animal habit, why they read on agricultural school and future data on what plans students have for future education and careers.

The main purpose of this Master´s thesis is to examine how Swedish librari-ans manage and relate to social problems within the service to young visitors. To reach understanding in this subject, qualitative interviews with six Swedish public librarians have been conducted. As a theoretical framework the ideas of interactions and identity have been used. These concepts together with attitude and behavior, form the theoreti-cal model upon which the analysis of the material is based. The outcome of the study shows that social problems exists and affect the library staff?s daily work.

The project description is to draw an extension or annex to the existing Nationalmuseum building from 1866.The annex is designed to complement Nationalmusems activities and contain internal and public functions. Artentering the building must not be crossed by public visitors. Art and staff must be able to seamlessly move betweenthe extension and the main building. The new building includes a public study room for scholars working withthe collection of art on paper, workshops, conservation studios, art spaces and warehouses. Additionally, theannex is designed to host a large number of office spaces.With the renovation of Nationalmuseum they intend to open up the today built in south atrium.

The purpose of this study has been to investigate the views of five teachers on their own leadership, and on the way they make it work in the classroom. The method was a qualitative investigation consisting of separate interviews with five elementary school teachers from three different schools in the southern part of Stockholm. The results showed that a good pedagogic leadership, successful with the pupils, can be characterised as at the same time democratic and "situation adjustable". This includes the ability to formulate the rules of conduct clearly, to take decisions and to create a good working atmosphere in the classroom, so that the pupils can feel secure, and be able to learn and develop. That however, cannot be accomplished if the teacher only maintains a negative communication, reminding the pupils of what is forbidden.

The OMX-case entailed considerable uncertainty about the relationship between tax treaties and Swedish domestic law. Previous approaches to handle rule conflict between them was put out of action for the first time when an internal rule took precedence over tax treaties. The Greece-case came a few years later where there were hopes that it would be decided in plenary session to return to the view that prevailed before the OMX-case, which did not happen. Instead the Supreme Administrative Court ruled that the tax treaties shall in principle be given preference, but that in exceptional situations tax treaties can be infringed to an internal rule's benefit, so called tax treaty override. Such procedure is acceptable if the legislature gives "clear expression" of the intention of a certain type of income is to be taxed in Sweden, or that a particular new rule applies regardless of the provisions in tax treaties.The purpose of this thesis is to analyze the supreme administrative courts management of rule collision between domestic law and tax treaties in the Greece-case.

The ability to handle potentially dangerous and hostile situations on a military vesselrequires that the equipment works effectively with the personnel that use it. It is importantthat this equipment can be used by different people. An operator on a military vesselshall be able to handle information about hostile threats, navigation and the steering ofunmanned vehicles. A operator console should therefore be constructed in such a waythat the operator can handle a large flow of information. And the information given bythe technical system should be displayed correctly to facilitate the operators ability tohandle and interpret the information correctly, in order for the operator to make thecorrect decision at any given moment.
