Dagens trend av industriell tillverkning och konsumtion är av linjär karaktär. Material utvinns, blir produkter och hamnar sedan på deponi. Detta examensarbete har tillsammans med Industrial Development Center AB syftat till att skapa en mer hållbar industriell tillverkning inom Skaraborgsregionen, genom att forma en produktutvecklingsprocess i enlighet med cirkulär ekonomi. Cirkulär ekonomi förespråkar att avfall inte får förekomma och att produkter och material ska cirkulera i kretslopp. Projektet bestod därför av en bred förstudie för att samla och utvärdera ett stort område med teorier, processer och företagens ansvarsroller.

The purpose of this paper is to find out which portfolio theory one should use during a financial crisis. We will examine two different portfolio theorys, the Minimum Variance portfolio and the beta portfolio.We have chosen to study two different portfolios, and followed their development during the financial crisis with its start in 2008 and the IT bubble with its start in the middle of 2000.The data has been collected from OMX internet database making it quantitative study. The beta portfolio's objective is to follow the index and the Minumim Variance portfolio´s objective is to spread the risk by investing in stocks with low volatility. By following the two different portfolios, and compare the development to the index, we will be able to determine which theory is most suitable to use during a recession. The studyperiods we chose were both in a recession and it turned out that the most appropriate portfolio to use was the Minimum Variance portfolio because stock in this portfolio tends to be less sensitive to economic fluctuations..

Background and problem: The background to this study is the organizations increased difficulty to retain employees in the organization when more and more employees today choose to do their career in several organizations. The problem to keep the employees in the organization leads to several problems where the loss of experience reduces efficiency and increased risks and cost associated with recruitment are some problems that arise. The problem therefore faced for this study is: How can opportunities for career development within an organization created to get employees to stay over time?Purpose and method: The purpose for this study is to describe how organizations can create opportunities for the development of career that gets employees to stay within the same organization and make their career in this organization. The method used for this study is a qualitative approach where data is collected through semi-structured interviews in a case study.Empiricism: The empirical result have shown there are four factors that an organization should overhaul to create an opportunity for the development of a career that gets employees to stay in an organization over time.

The purpose with this essay is to study how students in elementary school are placed within the subject called ?svenska som andrasspråk?, or SVA. SVA is a subject specially designed to deal with the complications that students with a different native language encounter when trying to learn Swedish.  National school documents state that a student is to be offered SVA if he or she has a different native language than Swedish and if the headmaster decides it?s ?needed?. In this work I focus on the different factors which are involved in the headmasters decision whether a student should be in a SVA-class or a normal Swedish class.

 Title:              Not just words, classroom communication about subtraction in year 2Language:      Swedish with summary in English.Keywords:     Communication, mathematics, subtraction, teaching The purpose of this study is to analyze the mathematical communication in a classroom during a lesson in the field subtraction, and to find out how students describe their perception of mathematics that is communicated in the classroom.The study consists of the observations through the videotaping of two lessons in primary school grades 2 and student and teacher interviews related to these lecture occasions.Research indicates that Swedish pupils' mathematical skill continuously deteriorates in a national and international perspective, and that student experiences of mathematics in general are negative. The literature emphasizes the importance of communicating mathematics in various forms to deepen and develop understanding of concepts and mathematical operations. Communication must be generated between teachers and students but also between student and student to have a beneficial impact for the student.Our result demonstrate the different types of communication in the classroom but that communication does not always have a clear mathematical content in spite of teachers' mathematical intentions with teaching. The result also indicates that the mathematical communication that takes place, in essence, is a one-way communication where the teacher has a great opportunity to speak. The teachers perceived as oblivious to their own ways of communicating, but stressed in the interviews with an understanding of the importance of communication learning.

From underwater boat to submarine ? The development of the Swedish submarine service 1945-1960 The scope of this essay is the development of the Swedish submarine service during the period 1945-1960. The aim is to answer the following questions:- What kind of new technology did Sweden acquire when salvaging the German type XXI submarine off Gothenburg at the end of World War II?- In what respect did this technology differ from that of the Royal Swedish Navy and did it subsequently contribute to the tactical and operational development?- What tactical and operational development was accomplished between 1945-1960?The timeframe, 1945-1960, was chosen since this is when the analysis of the salvaged type XXI submarine and related effects was conducted. Furthermore, it is also during this time that the Swedish submarine service is beginning to evolve as a result of the new knowledge mentioned above and the experiences made by both the allies and the Germans during World War II.The theoretical framework primarily refers to the theories on naval warfare by Sir Julian Corbett.

This essay examines resident experiences and notions of the Gotland countryside and their ideas about the future. In particular the countryside is studied as both space and place. In space and place people interacting. People are therefore important components in the study of the landscape. One can say that the landscape and the interaction between people affect resident experiences and notions of the countryside, as well as people certainly affect the landscape.

The essay aims to highlight the newly arrived immigrant students? experience of social integration and social security in the Swedish school system, which is important for their further language and learning development. This essay aims to see it from the student's perspective. The main question in this essay is: What factors seem to matter the most for the newly arrived immigrant students in their language and learning skills, and what does the students themselves think about the issue? The study is based on a qualitative research method in the form of interviews and observations conducted in a multicultural school for a period of two weeks.

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

The purpose of this Master?s thesis is to describe the development of the most important libraries in Skövde, starting from 1830. We conclude our examination about 1940, when the municipal library has been active for almost ten years, and the libraries started by the temperance and working-class movements have been deposited at the municipal library. In order to explain this process we describe the development of the Swedish public library and its predecessors, such as reading societies and the popular national movements? libraries, as a background and comparison to the early libraries in Skövde.

Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.

The aim of our graduate work is to study the importance of image and shape?s in children's development and learning and also the preschool teacher?s views on image and shapes. Our research aims to explore the value of image and shapes creation and how it is expressed among children and in classroom activities. We are also interested in finding out how it differs from adults' views and what materials teachers use to promote the image and shapes creation in the curriculum. In our own experience, image and shapes activities are often structured differently in different curriculum activities.
