AbstraktStudien behandlar begreppskunskap inom området positionssystemet hos elever i matematiksvårigheter. Undersökningen har gjorts i årskurs 4 och omfattar naturliga tal avseende tiobassystemet.Studien består av en kvantitativ undersökning och en kvalitativ del med intervjuer.Resultatet av studien har organiserats i tre områden som har betydelse för individens utveckling av matematiska begrepp. Talområdet 1-10, talsystemets uppbyggnad samt förståelsen av stora tal.Av resultatet framgår att förståelse av ett begrepp kan vara mer ytlig än den ser ut att vara. Brister i grundläggande begreppsförståelse kan leda till att räknesvårigheter uppstår. Svårigheter är bland annat begreppen talsort och platsvärde, särskilt i stora tal.Sökord: begrepp, matematiksvårigheter, positionssystemet, schema, specialundervisning, tiobassystemet..

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

This master's thesis reports on our investigation of how the public librarian's professional identity is formed and what it is formed of. We have considered factors such as: education, competence and daily tasks. In order to fulfil this aim we have used a literature study on concepts such as competence, education, professional identity and profession. We have also carried out an empirical study where we have interviewed nine librarians on public libraries. The method of analysis is qualitative.

The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.

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.

The study is a qualitative survey with the purpose to through interviews with Employment Office social workers examine their perception of possibilities and obstacles in the employment market for immigrants. This purpose is specified through two specific problems; how are cultural and ethnic affiliations portrayed in relation to what is perceived as Swedish in the communication with Employment Office social workers and whether they reckon that the specifications in the employment market are pragmatically or normatively motivated. The materials are presented using a social constructivist perspective and in relation to previously conducted research and our chosen theory. The results are presented and analyzed in themes. The main conclusions drawn from the interviews are that it primarily is the individual prerequisites that are central, but that structural factors also affect the entry into the employment market.

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

This thesis describes the processes of establishing wind farms in Sweden. The workcontains a thorough literature review regarding both the establishing process andproject management, including complex project theory. The main part consists of theexecution of 15 interviews with organizations involved in wind farm establishment.The result of these interviews laid the foundation for a process description identifyingdifferent steps and activities in these types of projects. The outcome was thencompiled in a project model, which includes five phases and four processes.When analyzing the project of establishing wind farms from the theory of complexprojects one discovers that the amount of different requirements and stakeholdersnecessitates a systematical and dynamical project structure. Since projects are in needof different types of competences there are also many consultants and contractorsinvolved.

With this empirical essay I want to research how and why pedagogues use music in their preschool activities. Music is important to me and in relation to the new educational plan I have cautions about that the esthetic subjects may be less prioritized than before. The purpose with my study is to find out preschool pedagogues perspective in learning and evolving children?s educational matters through music. I base my literature theories in this study on Vygotskij and Fröbels theoretical perspectives.

Detta examensarbete är en studie om matematik i vardagssituationer i en svensk förskola. Syftet med min studie var att undersöka vilken matematik som uppstår i av- och påklädningssituationer. Ytterligare ville jag ta reda på hur pedagoger arbetar för att lyfta fram och stimulera barnen för att upptäcka matematiken i dessa situationer. Jag har valt att göra en kvalitativ studie. I den empiriska undersökningen använder jag ostrukturerade observationer av pedagoger tillsammans med barnen i tamburen, som kompletteras med löpande protokoll.

The purpose of this study is to give a description of how six pedagogues in the third and fourth grade teaches mathematics and which working methods they use. When using the term working methods it is implied that it can for example be outdoors pedagogic, laboratory material, problem solutions et cetera. This material can both be an everyday material or a pedagogical material. The research was carried through by interviews and observations. Six pedagogues were interviewed in two different districts.

This study?s aim is to investigate how multilingual students learn mathematics and teaching strategies used to support the students? development of knowledge. A total of eleven scientific articles were selected for analysis and comparison. The results showed that visual representation, multimodal forms of expression and the students? whole linguistic repertoire constitute central resources for learning.

Title ?Att attrahera nya målgrupper med planerad kommunikation?Author Magnus Ejerhed, Anna Johansson and Caroline JägersvärdCourse Bachelor thesis in Media and communication studiesSemester Spring semester 2008Tutor Britt BörjessonUniversity the University of GothenburgAim the aim of the study is to describe students attitudes to Volvo IT as an employer.How can Volvo IT improve their communication to students?Method A quantitative approachMaterial A questionnaire which has been given to 122 students in economics atHandelshögskolan in Gothenburg and Industrial economics at Chalmers Universityof technologyMain results The main results of the study are that most of the students in economics andindustrial economy are positive to work as management consults. They also havean optimistic attitude to work as intern management consults in a large company.The students don?t regard Volvo IT as a possible future employer; neither do theyhave a good knowledge of the organization.Conclusions It is very likely that the students don?t regard Volvo IT as a potential employerbecause they don?t think of Volvo IT as an organization in management consulting.Volvo IT has to make their management consulting, Fortos ManagementConsulting, more visible if they are going to make the students more interested ofthem as an organization in management consulting. They have to inform theirtarget group what new competences they are looking for.

AbstractAim; With this study we aim to know more about the possibilities teachers in pre-school regard useful in their work, when encouraging children?s language development. In the study we are inspired by the thoughts and ideas of Lev Vygotskij. Method; We interviewed eight trained teachers at four pre-schools in Sweden. The interviews were recorded and later written down.

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.
