AbstractBy finding out the pupils' choice of strategies for problem solving, we as teachers, can get a better understanding of their way of thinking, and thus also help them develop in their learning of mathematics. In a classroom environment where several different strategies could be found, the pupils' learning is facilitated as they, with the help of classmates, find positive and negative attributes of different kinds of strategies. The pupils are, in other words, each other's resources, rather than competitors. The main point is that the classroom environment, as well as the role of the teacher in the classroom, are both key elements for good mathematics learning.In order to increase the understanding of the pupils' choice of learning strategies, a survey was performed based on two school classes, one third grade and one six grade class at the same school. Both classes received the same mathematical problem to work with, and the strategies observed were analyzed and compared.

Background: Myocardial infarction is the most common individual disease among people in the west world. In Sweden there are over 50 000 women and men who get myocardial infarction every year and about 40 % of them dies. Exercise training is one part of cardiac rehabilitation and since 1980 Sweden use the guidelines from that time. Aim: The aim was to review exercise-training modalities in cardiac rehabilitation after myocardial infarction and the physiologic- and psychological effects. Method: Facts were obtained by searching through the database PubMed for articles published from 1994 and ten years forward.

This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

Since some years Linköping has invested in biogas production, mainly from offal's, residuals from food industry and manure. The municipality goes for biogas in the local traffic and in all transportation. It is also possible for private car owners to run their cars on biogas. The purpose of this essay is to perform a cost-benefit analysis and examine if the project has been beneficial from a social point of view. The effects have been identified, measured and monetarily valued. The essay is limited to include the year of 2006 only.

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

The purpose of this study is to examine how teachers and pupils experience the use of fictional literature as a tool for language development in the teaching of English as a foreign language. Through surveys and interviews and with Vygotsky?s theory on development in a social environment as a theoretical base, I examine which methods are used to promote language development and also which functions pupils and teachers consider fictional literature to have in the teaching of English. Results show that teachers consider fiction to be among the top methods to get pupils to learn English. Teachers and pupils both favour the use of fun and stimulating reading activities as well as group activities where learning is social to go along with the reading of fiction.

Facebook has over 665 million users worldwide and has created a new venue for companies to interact with their stakeholders. However, since it is a new phenomenon it brings some uncertainty and confusion as how to manage the communication on Facebook, and it is only recently that research and literature has become available on this topic.The purpose of this study is to investigate how three chosen companies within the travel industry communicate on Facebook. We also compare the results to the existing literature to see how they can improve from a theoretical point of view. We thereby hope to shed a light on, and add knowledge to, a research area where we have identified weaknesses. In order to fulfill our purpose, we used a quantitative content analysis as well as qualitative interviews.The major findings in our study on Facebook communication include a lack of strategy and target audience awareness, as well as a self-centered communication.

The society of consumption exposes us to a lot of information, where advertisement constitutes an extensive part. Due to its expanding, advertisement receives a natural and obvious space in our everyday life. This study aims to investigate how social and cultural values can be mediated in advertisement. The focus has been put to ideas related to health and fitness in the advertisement of power drinks. The thesis takes social constructionism as a starting point, and combines image- and critical discourse analysis in purpose to analyze the pictures.Sociology of consumption, construction of identity, lifestyle and everyday life all constitute an essential part of my analysis.

The purpose of this essay is to study the public debate on the subject of creationism, the belief that there is a creator of all life on earth. The study is focused on creationism in different forms in schools and the more general discussion of creationism as an alternative to the theory of evolution. The overall question is what should be taught as the origin of life: Evolution or creationism in various shapes and forms? The essay consists of an overview of previous research in both the USA and Sweden, and an analysis of argumentation on the issue in newspapers. A comparison is made between the USA and Sweden.The analysis of newspapers shows that there are some arguments for different forms of creationism but there are considerably more arguments against creationism.

The purpose of this paper is to understand why education is a human right. I will look at works by the late Paulo Freire, a Brazilian educator. Paulo Freire worked for many years on developing a pedagogy to promote humanity. His goal was to demonstrate that a literate person will ultimately live a better life because she will be free from oppression and domination.I chose to study Paulo Freire as a tool in proving why education is a human right because throughout his work he demonstrated the need for people to be literate in order for them to be considered ?truly human?.

The goal of this qualitative essay is to approach the knowledge of people who commit crimes. From a development psychology point of view, questions relating to childhood ang growth are some of the important subjects we choose to discuss. Our purpose is also to reveal the linkage between criminal behavior and different theories of the above mentioned perspective. To bridge the gap between the general and the individual, our survey was based on profound interviews with four inmates in prison. This offer an opportunity to capture the individual´s inner thoughts, feelings and experience about the criminal action.

This essay takes its starting point in the making of a new national general school curriculum for the Swedish elementary school. The purpose of this essay is to estimate what the policy makers intended with the new policy documents and relate that to how a few teachers perceive these changes. In order to get an understanding of how the teachers view these changes I have done qualitative interviews with four teachers which all work in the Swedish elementary school.Theories on "implementation" and "street-level bureaucracy" are used to analyse my empirical material. My results tell that there is a difference how teachers relate to the new curruculum and the policy makers' intentions with it. That can be explained by the fact that teachers' work is complex and as to they work in a complex organization..

In the proposition Nya förmånsrättsregler, 2002/03:49, the government suggests a new bill of beneficial rights, or FRL. The proposition has several changes, mostly for The Banking system. One of the changes is that the banks´ individual beneficial rights shall be replaced by a general beneficial right, where the beneficial value never exceeds 55 percent of the value of insurance bonds. Previously, the beneficial value was 100 percent.The purpose of this essay is to evaluate the relationship between the banks´ activities, and the new bill of beneficial rights, especially what the effects will become for the public companies within the printing houses, with 1 - 49 employees in the Skåne Region.The survey includes a total of 142 companies and it was distributed via e-mail. The conclusions from the study are that there are tendencies of increased difficulties for companies to get their credits granted by the banks.

In this essay I trace the historical theme in Djuna Barnes?s Nightwood, stressing the importance of the concept of forgetfulness in the text. Read alongside Nietzsche?s On the Use and Abuse of History for Life as well as his later thoughts on genealogy, the novel can be seen to concern itself with that same dilemma of history that he articulates in his philosophy. That is: how not to be overburdened by historical knowledge to the point where it petrifies life and prevents any real and novel action, and how at the same time, to make oneself conscious of ones own historicity, so as not to be governed to much by the past.I argue that Robin inhabits what Nietzsche would call the unhistorical state, whereas the other characters, in contrast, struggle with their relation to the past.

Degeneration of trademarks - a legal construction or a marketing problem? This paper discusses the issue of degeneration of trademarks. The study has its starting point in the conflict that may arise between the principles of marketing and the legislation concerning IP rights and market law. In this study several verdicts are studied in which degeneration has been addressed. Analyzing these rulings as well as the current legislation in the light of marketing theory, a conflict between marketing and legislation can be noted.
