Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

The present study investigates the relationship between narcissism, using identified facets in the five-factor model for the grandiose and vulnerable narcissistic personality, and job performance. The results, based on analyses of correlations from previous studies, meta-analyses and norm-data, show general differences regarding the grandiose and vulnerable narcissistic facet profile and their respective relationship to job performance. The results confirm previous study implications of the facet level data?s ability to capture aspects of the personality that a broader measure misses. Similarly, the results demonstrated that facets could differentially predict job performance in both a negative and positive direction.

The aim of this Master?s thesis is to examine how health information is integrated into knowledge in an everyday health related context on the web. The more specific aim is, from a LIS point of view, to map knowledge related discourses with the focus on pregnancy, in discussion forums on Swedish health related web sites. The following main questions in this paper are: (1) a) What discourses on pregnancy knowledge can be found and b) how are they expressed? (2) What are the functions of the recognised discourses? and (3) what are the relations between the identified discourses? The theoretical and methodological starting-point is discourse theory with the main focus on discursive psychology according to Wetherell?s and Potter?s theoretical and empirical work.

Due to lack of knowledge about motivation in Swedish for adult immigrants (SFI ), I have chosen to write about motivation. Motivation is a complex concept to understand. It has different meanings depending on what context the term is put in. In this study , you will read about the external and internal motivation . But also about integrative and instrumental motivation.

This study is about differences in knowledge regarding animals. In the study five year old preschool children from a city were compared to five year old preschool children in the suburbs with multicultural background. The study is also about where children´s knowledge about animals comes from and how educators can make a positive difference. To find this out standardized interviews was used on 23 children from four different preschools, two preschools in the suburbs with 15 children and two preschools in the city with 13 children. A survey was sent out to the educators within these preschools to gather background information on what the children do regarding animals.

Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.

The purpose of this essay was to increase the knowledge of and understanding about how teenage girls form their attiutdes towards sexuality and relations. The focus has been on discussing the research-question from four factors of influence chosen by the writers; sexual education, media, friends and family. Our intention with the study was also to take part of the teenagegirls´thoughts, attitudes and opinions in the matter, which is to keep the discussion on a structural level. The study is based on qualitativ interviews, in so called focusgroups, with all toghether eight girls in the ages 14-15 years, students in the ninth grade. The study has a postmodern feministic approach combined with a fenomenological and hermeneutic position.

The aim of this study was to describe home care personnel and their experiences in palliative care. The design was qualitative and data were collected through interviews. Five home care personnel were interviewed, all women, whom have experience of palliative home care.The material was then analysed with qualitative content analysis and eight main categories, derived from experiences of home care personnel, were identified: relationship, safety, quality of care, a better end-of-life, routine, information, knowledge and competence, and work environment. The result showed that all participants of this study identified themselves as family members of the patients whom they had cared for during a long period of time. Additionally, the participants were emotionally touched when the patient died.The majority experienced that the patients do receive good care in their homes.

Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..

Officially, the EU gender policy since 2000 has been guided by the strategy of Gender Mainstreaming. This strategy aims to promote gender equality and is informed by a feminist ontology which stipulates that women are structurally subordinated.In this essay, I examine whether the European Commission has adequately adhered to this gender policy in its free trade negotiations with the ACP (African, Caribbean, and Pacific) countries as part of the Cotonou Agreement. As a result of my text analysis of documents related to the negotiations, opinion pieces by interested actors and policy papers of the EU, I find that the Commission does not act in accordance to its stated gender policy.To explain this discrepancy between policy intent and actions, I employ postliberal feminist theory and Robert Putnam's Two-Level Game Theory Model. By analyzing statistics and published research, I explore how gender issues are being represented politically on a domestic and international level.My findings show that a key cause of this discrepancy lies in the low levels of female participation in the political institutions of the EU and ACP; a lack of participation that is especially pronounced in the area of international economics. In explaining the constraints on female participation and the prospects of full implementation of the EU's gender policy in the international political economy, I emphasize the role of culturally and historically gendered institutions..

This essay studies the practice of both the political and the administrative leadership at the municipal level from the point of view of the politicians and the chief officers leadership role, and the relationship between politicians and administrators. I discuss and analyse how politicians and senior officials practice leadership, differences or similarities and if their practice of leadership raises any challenges in a democratic framework at the municipal level. I conducted interviews with the municipal political leader and the head of administration at the municipal level in Karlshamn and Sölvesborg. In the analysis I discuss communication as a leadership process which highlights ?enabling elements? and potentials of the leadership process.

The theme in this report has been how to benefit experience from accident investigations. The demand on the municipality to perform accidet investigations is relatively new, and maybe they aren?t clear what the demands means. This causes that there might be a problem to benefit experience from accident investigations, for improving the overall safety in the municipality. The main purpose of this report has been to clarify how experience from accident investigations, can be of benefit to society on a local level.

I have in this essay focused on the attitude towards the medieval muslims in swedish textbooks, in the subject of history from the years between 1954 and 2012. I have made an analysis on the discourse in the books and what they says about the muslims who lived before 1500 AD. The theory I have is a Postcolonial one from the authors Edward Said, Ania Loomba and Leela Gandhi. I have also analyzed the rhetorics the authors have used in every textbook. The results I have identified is that the attitude towards the muslims have changed during the years, from a generalizing view that says that the muslims were driven by the religion and that they were different from the Christian European society that existed during the same time.
