In this report the balconies? abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinforcement bar that holds the balcony runs through this heel.
Hur gymnasieelever ser på sig själva : Skillnader mellan pojkar och flickor
AbstractThe purpose of this essay is to increase the knowledge of which strategies students with reading and writing disabilities or dyslexia use to learn in secondary school. The study aims to examine the following questions:Which coping strategies do students with reading and writing disabilities use in their studies?How can remedial teachers support students with reading and writing disabilities in their learning process?The study consists of two interviews with a total of three hours recorded material made with a secondary school teacher who teaches Swedish and English. The teacher has experiences of reading and writing disabilities herself but also from teaching students with dyslexia. The interviews are constructed into a lifestory describing experiences of reading and writing disabilities in school, during teacher training and as a teacher.
Lärande på lika villkor : En intervjustudie om individanpassad undervisning i ämnet svenska
This study is a survey concerning learning on equal terms. The purpose of the survey is to get a look into how teachers of today integrate students to obtain an individually adapt education. A good education is where every single student can evolve from an individual level and how education is adapted to let high-achieving students keep their motivation and thus develop from their own level of knowledge.Data has been collected through a qualitative method using semi-structured interviews. In the result the answers of the interviews are presented and it shows that teachers turn their focus towards low-achieving students. Low-achieving students are more in need of support to reach the required amount of knowledge, but that the high-achieving students must not be forgotten by the teachers. .
Stigberoende och spelmatriser : Varför har landstinget i Värmland valt att ansöka om att få gå ihop med Region Västra Götaland?
The aim of this study is to try to explain the process using both an actor driven perspective as well as a structural perspective examining the reasons why the County Council of Värmland wants to merge with Region Västra Götaland. The answers to the following research questions are sought to shed light on the problem: What constrained the discretion of the political actors in the choice of region to merge with? Which role did different political actors play? Does the study provide Game Theory, from Rational Choice theory, and Path Dependency, from Historic Institutionalism, a new perspective and strength especially when bringing them together? The study is limited to two policy areas, health care and regional development policy. The structural background is drawn upon the Annual Report 2008 of the County Council Värmland, the Regional Development Program and Regional Transport Infrastructure Plan 2010-2021 by Region Värmland. The chronological order of decisions and events is drawn upon protocols from various regional political organs all linked to the municipal of Värmland and the correspondence between the officials of Värmland?s municipal and the Legal, Financial and Administrative Services Agency of the State.
Fotbollsledare om styrketräning för barn : ? når forskning ut?
Fysisk träning för barn har alltid varit ett kontroversiellt ämne som berör såväl etiska och fysiologiska som medicinska frågor. Styrketräning är den form av träning som ställer dessa frågor på sin spets. De svenska officiella organen Idrottens Forskningsråd (IFR) och Riksidrottsförbundet (RF) har genom åren lagt fram rekommendationer och riktlinjer som ska fungera som underlag vid utformning av den träningsverksamhet som bedrivs i idrottens föreningsliv. Eftersom forskningsrön har förändrats i takt med forskningsframsteg har också rekommendationer och riktlinjer från officiellt håll varierat över tid. Syftet med föreliggande studie var att undersöka om fotbollsledare har kännedom om de senaste rekommendationerna vad gäller styrketräning för barn.
Passivhus det långsiktiga valet. En konkret jämförelse mellan konventionellt byggande och passivhus
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Barns pedagogiska material : En kvalitativ studie om barns användning av det pedagogiska materialet som finns på fem förskolor och om sex pedagogers tankar kring placeringen av det pedagogiska materialet
?Childs pedagogic material ? A qualitative study of child?s use of pedagogic materials available at five nursery schools and about their teachers thoughts about the display of the pedagogic material?In the nursery preschool the environment and the educational materials have always had a central place. That's why it has been chosen to study and observe five preschools and interview sex teachers, in an attempt to understand the teachers thought about the choice of material and the choices of material that the children used. The reason I do this is to see what the underlying idea about the materials the children use is, and why educators choose to make certain materials visible. The purpose of this study is to examine the educational materials that are used to stimulate children´s learning and examine what determines the choice of educational materials.
Arbetsvillkorens samband med sjukfrånvaro och sjuknärvaro : En studie av hemtjänstpersonal
Sickness absence is a measure of health and is therefore an important issue. To get a complete picture it´s important to also include in the discussion sickness presenteeism, working while ill, and voluntary absence, staying at home without illness. Working conditions have been proven to play a role for the three aspects which is why this study aims to further investigate the connections between them. The method used was secondary processing on interview data collected from two home care teams, one having a low and the other a high sickness absence. The results showed that there were big differences concerning working conditions, where the group with the high sickness absence perceived more stress, less control and less support from colleagues and superiors.
Att kommunicera mångfald : En undersökning om kommunikation och engagemang inom Landsrådet för Sveriges Ungdomsorganisationer
AbstractTitle: Communicating diversity ? A study about communication and involvement in The National Council of Swedish Youth Organizations.Number of pages: 58Author: Frida SamuelssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Autumn 2006University: Division of Media and Communication, Department of Information Science,Uppsala UniversityPurpose/Aim: The general purpose of this essay is to analyse how the member organizations of LSU ? The National Council of Swedish Youth Organizations, see the communication,activities and their influence over the organization. I aim to do an analysis of the target group to find out if the lack of involvement in LSU is caused by communication problems.Material/Method: The method of this essay is quantitative and is based upon a web-survey.The chairmen of the member organizations have been asked to answer a survey about the communication in LSU. To get an idea of how widespread different opinions about LSU are the empirical data has been made into graphs to show the frequencies and also cross tabulations to find out if there are any correlations between the variables.Main result: This study has shown that the problem with involvement in LSU is only partly a communication problem. One important result is that many member organizations feel that LSU doesn?t listen to their opinions and they express a wish to have more influence over the organization.
VISSERLIGEN S? KAN MAN INTE OPERERA EN S?GVERKSMASKIN, MEN MAN KAN JU LIKSOM G?RA N?GOT F?R DEMOKRATIN. En diskursanalytisk studie om folkh?gskolans roll i det nyliberala samh?llet
In this bachelor's thesis, we investigate the Swedish folk high school?s role in neoliberal society, which is analyzed through the lens of Norman Fairclough's critical discourse theory as well as Erving Goffman's theory of social deviants. The focus of our study has been participants in creative education, such as art, theater and creative writing. Our findings include that participants at folk high schools find great value in their education, both creatively and personally. They note that they have experienced a large amount of
personal growth, regarding both openness towards others and higher confidence and their own abilities and identity.
Varför En Reformerad Gymnasieskola 2011? : En reformanalys utifrån rektorer och lärares uppfattningar ? kopplat till John Deweys teorier.
This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.
