In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.

The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.

The attitudes towards nature conservation in forestry are based on the individual forest owner. The theme of the interviews is the opinion on nature conservation in forestry. The purpose of this study is to identify if there is any difference in attitude to nature conservation in forestry according to the age of the forest owner. The study discusses different factors that affect the private forest owners consideration of nature conservation and give an insight in different generations attitude to nature conservation. Other topics that are discussed is if future change of generation will change the consideration of nature conservation in Swedish forestry and what is needed to enhance the interest in nature conservation among forest owners.This study is the result of interviews with a number of forest owners in the county of Uppsala, Sweden.

This study is grounded in an interest in the Swedish Upper Secondary Schools? role as an educator of democratic citizens, with a specific interest in the moral and cognitive development of Upper Secondary School students. Development in these two areas is treated as results of citizenship education.The purpose of the study is to examine moral and cognitive development of students in Upper Secondary School to see if there are any structural differences to be found between the Upper Secondary School programs that are vocationally oriented and the programs that are preparing for further studies on higher levels ? since these differences have been both theoretically and empirically implied. The study is based on an enhanced version of Lawrence Kohlberg?s stages of moral development (with teachers? evaluations of students? capacity as a reference point of the students? actual level of moral development) as well as on Kieran Egan?s theory of development through the use of cognitive tools (as seen in five different ?shapes of understanding?).

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

Previous research about contextual effects on advertising has mainly focused on the editorial context, while advertisements' broader context has been overlooked. This paper aims to take a broader perspective on advertisement context. Its purpose is to get an understanding on how physical exercise influence the effectiveness of print advertisements, and furthermore to look at the effects of thematic incongruence between ad and the physical environment. We hypothesize that physical exercise increase ad effectiveness through affective priming and that thematic incongruence is beneficial for ads' effectiveness, especially after training when awareness about the environment is higher. A 2×2 experiment was conducted in a gym, where each respondent was exposed to either an incongruent or less incongruent ad, before or after physical exercise.

Abstract Youths and adolescents have for a long period of time, and at a high degree, beenabsent from the party political stage. The causes for this have been discussed inthis essay through a quantitative survey made in an upper secondary school class,consisting of some 19 subjects in the municipality of Kalmar. Tied together withrelevant literature and discourse on the subject, the essay has dealt with thepossible societal-, system- and individual barriers for political interest andinvolvement. Central questions for this essay has been for instance; age, gender,social background, geographical domicile, as well as the decline of ideology, theforms of current party politics, political interest, political engagement and soforth. The concluding remarks contain not only a mix of these barriers existing,not exclusively, for young and adolescents but different ground for them as well.On the one hand, there exist barriers which exclude youth from the conventionalpolitical life, but on the other, the more individualised youth of today, prefer to agreater extent not to participate under the conventional circumstances that partypolitics has to offer.

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

This thesis deals with the supranational organization of European trade unions. The European trade union movement is, via its umbrella organization the ETUC, an institutionalized social partner within the European Union. The ETUC is a very diverse organization with great potential of conflicting interest among its members. This thesis therefore seeks to explore the dynamics and interest heterogeneity of the ETUC. Drawing on previous research and literature it formulates a number of hypothesises to test what variables that influence the member organizations policy preferences (i.e.

In the rate of changes condition of the market in shape of increasing competitiveness situation, local as global, this leads to that logistics has to be developed in the same rate. Logistics has been developed from the military and after the war, logistics was figurative to the companies transport- and store problems. After this, logistics had been divided up into four different time phases (the seventies to the 21:th century). All these time phases have together develop the spectacle and focus of the logistics today. Afterward further developing of the logistics approach to Supply Chain Management (SCM) and afterward SCM, Demand Chain Management (DCM) was developed in aim to secure that the right products were manufactured on the basis of the end customers real requirement and wishes.This paper is taking the aim and problem formulation as a starting point.

This essay discusses the problems with the high rate of long-term sickness leave among women in Sweden. It is based on interviews with six women suffering from stress-related illness. The results show that these women hardly ever recieved an explicit diagnosis and therefore did not feel that their illness was acknowledged. In the abscense of measurable symptoms they were sometimes stigmatisized and accused of simulating their problems. From this position they tried to legitimize their situation by presenting themselves as respectable women.

This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.

The main purpose of this C-essay is to answer the question: What have been the consequences and effects of the merit point system on language studies and the parties concerned (teachers, students and principals) during the school year of 2010/11?The merit point system is the result of a political decision and was implicated for the first time in the Swedish upper secondary school during the school year 2010/2011. Being a completely new phenomenon it is of great interest and importance to study its effects.The study in this essay also aims to verify, falsify or nullify two hypotheses very often referred to in the political discussions regarding the merit point system:The merit point system will replace affection and interest as main reasons for language studies in upper secondary school and cause a rectification amongst the students choices of additional courses.The merit point system will have a segregating effect upon society and make it harder for people to rise in society through education in the future.A verification of these hypotheses would imply the appearance of an increased rectification amongst students as well as an orientation towards an in the future more segregated society.The empiric material has been collected and examined with qualitative as well as quantitative methods (questionnaires and interviews) and belongs epistemologically to the phenomenological and hermeneutical traditions..
