Föroreningstransport i grundvatten : En modelljämförelse
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.
Svenska företags etableringar i Sydkorea och Japan : En jämförande studie av den koreanska och japanska marknaden
South Korea is one of the fastest growing economies of the world and experts claim that it?s headed towards the same direction as Japan. This doesn?t imply that the countries are similar to an extent where companies don?t have to consider the differences while entering the host market. This study was conducted for the purpose of giving a view of the business climate in the countries and thereby could help companies who see the countries as potential host markets.
Förskolechefens ledarskap : En studie om fem förskolechefers syn på sitt ledarskap
The purpose of this study was to examine how five preschool managers are looking at theirleadership and what difficulties they see in their leading. To live up to my purpose I askedthe following research questions: Which parts in their mission do the five preschoolmanagers see as problematic in relation to the curriculum for preschool and the schoolsinspectorate quality investigation? How do the preschool managers describe their leader styleand leader ideals, and is their any difference between the two of them?The method of this study was qualitative interviews with five preschool managers. Theresults that I found was that the most of the preschool managers see their leadership as coproduced(like in Ludvigssons research 2009) with the teachers and that the preschoolmanagers often find other difficulties in their mission compare to the quality investigation(School inspectorate 2012). I also found that three of the five preschool managers thoughtthat they weren?t present enough in the preschools because of their many tasks.When I tried to classify the preschool managers leader style I found that they vary betweendemocratic and authoritarian leader style in decision-making like in Tennenbaum andSchmidt?s (1973, p.

För att nå syftet genomfördes en analys av uppgifter i två läroböcker för Matematik A.Undersökningens resultat visar att alla sex matematiska kompetenser finns representerade i läroböckernas uppgifter.
Bibliotekarie ? vad är du, vad kan du, vad vill du? - en kvalitativ studie om bibliotekariestudenters och utbildningsrepresentanters syn på yrkesidentitet, kompetens och karriär
The aim for this bachelor thesis was to form a deeper understanding of librarians? occupation and professional identity and therefore we have examined library students? and educators? view on professional identity, competence and career possibilities. Our take on this was that there seems to be little interest in managerial positions and we asked ourselves why this is and if we could see a change in interest in the librarians to become. As our theoretical framework, we chose Andrew Abbott?s, 'Theory of Profession'.
100 tigrar i djungeln : En studie om Posttraumatisk stressyndrom hos barn
Abstract This essay will present actual research around the concept of Post- Traumatic Stress Disorder, how it can reveal itself in school children and how it can influence young people?s learning ability and capacity to retain knowledge.The purpose is, above all, to clearly diagnose PTSD so that children with this complex of problems can receive good possibilities in learning and understanding.The question at hand is responded to by interviewees with an expertise on the subject and one ?story?, collectively with literary studies.The results illustrate that there can be neurological and biological, as well as social explanations for PTSD but it is seldom a permanent diagnosis. It is though something to take very seriously. PTSD can lead to severe psychobiological consequences, mostly by causing damage in one particular part of the brain, known as hippocampus. The hippocampus is essential in terms of memory and concentration.
Demokratisering utifrån- En fallstudie om demokratiseringsprocessen i etniskt splittrade Bosnien Hercegovina
After the fall of communism in Yugoslavia the ethnic resentment grew stronger and escalated in to interethnic civil conflict in 1992. After international intervention the General Framework Agreement for Peace (GFAP) installed peace in 1995. The treaty's aim was not only to establish peace but also to institute democracy in Bosnia. The OSCE were given the task to implement democracy within political institutions and civil society. This in a country with a lack of democratic experience and where great problems with ethnic antagonism still exists.By using democratization and transition theory this single case-study examines how democracy is implemented in Bosnia by the OSCE and clarifies difficulties that this democratization process is facing.
Standardisering kontra flexibilitet : En fallstudie av utvecklingsprocesser
Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization.
Problemlösning : - att välja strategi
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.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Politisk kommunikation och IKT : En analys ur politikernas perspektiv i Västerås kommun
The purpose of this paper is to see how politicians use Internet communication in their daily work and how they use it to interact with citizens of Vasteras city. To reach my conclusions I used both theoretical methods such as literature studies and qualitative interviews with the towns 11 trustees. Accoarding to this study the politicians saw not only a lot of potentials and advantages in Internet communication but also many difficulties and obstacles. In this case the cons far exceeded the pros. One of the main reason is the bad experiences which caused by rasist attacks/threats made to politicians and also the difficulties in handling of sensitiv documents which was seen as a stress factor.
Gråzonens barn -En studie i gränslandet mellan normalitet och avvikelse, mellan individen och kollektivet
The purpose of this study is to research into the role of the citizen and the educational system in Sweden throughout periods of time based on previous theoretic works, and also to deepen the understanding of students with special needs in Swedish education focusing on the primary school years. This shall be carried out by illustrating the different points of view and choices within the educational system that are at hand for students with concentration difficulties and social difficulties.I will analyze these points through a cultural and social perspective on contemporary society in order to contribute towards today?s discourse on the norm. The result of this empirical investigation presents a dilemma existing in the democratic educational system of today. Nationally and internationally, the educational system has been structured around a normative system containing both rights and duties that effect everyone working within it.
Barn med lässvårigheter och bibliotek en användarstudie om några barns erfarenheter och upplevelser av bibliotek.
The purpose of this study was to examine how some children with reading problems experience and use libraries. The main problem was: How do dyslectic children experience and use libraries and how do they handle their reading difficulties when using libraries? The questions at issue were: 1. Do children with reading problems use libraries, and if so how? - in which purposes do they use libraries? - which materials and services do they use? - why dont some children use libraries? 2.
Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp
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.
Musikens roll i förskolan : Musikens roll i förskolan ur fyra pedagogers perspektiv
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.
