Empirical research shows that a possible reason why Swedish students mathematical knowledge deteriorates can be a too big focus on imitative reasoning, i.e. recalling solutions or follow algorithms, and a lack of creative mathematical reasoning, i.e. when a student construct his/her own solution and motivates its plausibility with mathematically well-founded arguments. The purpose of this study is therefore to examine if, and in what way, lecturers can provide students an opportunity to learn creative reasoning by simulating creativity in their presentations of examples. Six lectures were observed and 22 task situations were analyzed with respect to three aspects; reflection, plausibility and mathematical foundation, which are to be present in the situation if the reasoning will be seen as simulated creative.

The purpose of this paper was to look at the perception of self-determination for adults with intellectual disabilities from their perspective. We wanted to examine the experience of the space available for self-determination in some key areas of life, and how their own thoughts and ideas have been addressed by others. Through interviews with six people with intellectual disabilities, we have found that a single definition of self-determination is elusive. The key seems to be that you get the opportunity to do what you want, to have your voice heard and to receive and take responsibility. The space for self-determination is perceived by respondents as both large and small.

The Art Library uses the newspaper cuttings archive to provide her customers with newspaperarticles about art. This archive has the following problems; there is little space left inthe paternoster lifts, the articles can only be found on keyword and to maintain the archive,much labour is required.This research aims to find out how the Art Library can provide her customers with newspaperarticles which will cost as little as possible.Six possible solutions are given. Out of these the solution with "Artikel-sok" was recommended.According to this solution the Art Library should no longer maintain the archive, butuse "Artikel-sok", a database from Bibliotekstjänst which contains descriptions of articlesfrom many Swedish newspapers and magazines. These articles can be ordered from Bibliotekstjänst.The old newspaper cuttings archive will be used for articles from before 1979,because these are not being taken up in the "Artikel-sok"..

Secondary schools have for decades debated whether they promote social reproduction which is considered to generate the homogeneous student compositions. The gap between the academic programs and vocational education programs is considered to increase. What in recent years has appeared in research is that the gap is increasing most tend to be in the specific academic program, particularly in science. This paper's intention is to describe the science program at a local level and the pupils who were admitted to the science program autumn 2009 on the basis of an educational sociological perspective. The survey consisted of a census in which all students were given the opportunity to answer a questionnaire.

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production. The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.

Stroke is a widespread disease in Sweden. Nurses play a central part for those who suffer from a stroke irrespective of where in the care chain they meet. To be able to meet the patients? need of care the nurse must understand his/her lifeworld. Each and every patient is unique and the experience of being struck by a stroke depends on personality and life situation.

The purpose of the essay is to study and create understanding to the bilingual students' perspective on their linguistic skills and the use of them as resources in a scholastic context. A qualitative method has been used to collect empirical data, based on the experiences and perspectives of the students. Bilingualism is defined and past research, which has shown how their bilingualism has influenced them, has been linked with this study. Definition of mother tongue and the meaning of mother tongue tuition for student immigrants' development have been discussed. This research has shown that the students feel their bilingualism is a natural occurrence.

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.

The effects of the climate changes are expected to generate several substantial direct and indirect consequences on both ecosystems and societies. It is the extent of the negative consequences that determents the vulnerability of the things or the ones exposed. The knowledge of the effects and consequences by a changing climate provides an opportunity to take measures to reduce the vulnerability.Our society?s vulnerability depends on how we choose to act out of the existing knowledge and what measures we choose to take. Karlstad municipality has good knowledge and perception of the increased flood risks the climate changes will generate and the probable consequences that most likely will follow. How the municipality decides to manage the flooding issue is not just affected by the will to mitigate the vulnerability but also by the vision to increase the number of citizens.

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.

This essay is a study of the motives and driving forces affecting how a food producer looks at, and incorporates, an environmental-labeling and its impact on their organization and strategy. Driving forces and motivations is an important part of a business strategy and impacts its content and its expression. Sustainability can be part of the overall company strategy but could also define the entire company. This study has shown that the main motive for working with eco-labelling is a genuine interest in issues concerning sustainability. This creates an opportunity for the company to communicate their environmental policies to their customers. For a company that works proactive and innovative with sustainability and climate issues, the new climate framework does not mean any major organizational or strategic changes.When the framework is incorporated in the organization the farms need to be analyzed with a climate impact perspective. This essay shows that this process, together with tools developed to handle the framework, make change in the way dairy farmers think and how they relate to their daily work..
