Elevers tillämpning av källkritik på Internet
This paper, called Pupils' practice of source criticism on the Internet, is investigating pupils? use of source criticism. The main research question was: how much knowledge pupils from an upper secondary class have about the use of source criticism, regarding examining data from the Internet intended for assignments. Furthermore, developing a suitable method to investigate this was included. The main research question led to further sub questions that aimed to answer to what extent pupils consider source critique criteria as sender, aim, up-to-dateness, credibility and dependence.The study has been conducted by using mixed methods, both qualitative and quantitative methods.
Tvärvetenskaplig undersökning av textil Broderiet från Tämta kyrka
There are several objects of age whose provenance and history has disappeared with time. The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.
Produktutveckling av koncept för isbanesystem
Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.
"Genus är inskränkt!" : En komparativt inriktad studie av genuspedagogik på förskolor i New York och Stockholm
The purpose of this thesis is to examine how teachers work and reflects on gender education in preschools. We also want to take part of how teacher?s thoughts are reflected in the physical indoor environment and how the environment is designed by reviewing the rooms furnishing and the selected materials. We will do this by visiting a number of preschools located in Stockholm and New York. We have chosen three questions to get the answers on our purpose.How teachers reflect around gender pedagogy are, and how the thoughts are expressed in the practical work.How the teachers communicate with their co-workers about gender pedagogy.How the teachers own thoughts and reflections on gender pedagogy have been expressed in the physical indoor environment where the children stay during the day. We have used interviews and observations as a method to gather the information that we needed to answer our questions of the thesis.
Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
Den svenska arbetarrörelsens utmaningar och visioner - En undersökning av synen på kollektivet i LO- Tidningen 1991-2005
In this essay I have studied the Swedish Working Class whose part of LO.Ideological texts in LO- Magazines is used to quote texts by collective orindividual terms. Method and theory material show high level of solidarity andequality while theory shows higher level of individualism and autonomy. Myresearch is closer to Boréus than Blocks. Politics taking under the 1980: s apowerful right turns holding a steady course through my material.The question in the essay is: What vision on the collective shows in theLO- Magazine in a time during individualization? Answer to this question is thatthe collective unofficially through LO: s: staff on central level tries to showstrength and unity with terms like solidarity and equality between the sexes.
Att mötas på de ungas villkor : - En kvalitativ studie om ungdomsarbetares erfarenheter av att bedriva stödsamtal med unga på internet
With this research we aimed to seek how youth workers express their experience of counselling on the internet compared to traditional counselling face to face with a theoretical ground in semiotics and symbolic interactionism. Our questions were 1) How do youth workers describe their experiences from anonymous, faceless online counselling? 2) How do youth workers experience the differences between online counselling and the traditional face-to-face counselling? 3) Which possibilities and difficulties do they see in online communication with adolescents? We used semi-structed interviews with seven youth workers. Six of those are active in non-profit organisations, and one in social services. The results from our interviews showed that the interviewees saw that misunderstandings were more frequent on the internet, but that online counselling with adolescents still was easier than in the face-to-face meetings.
Får jag ta med min bebis in? En fokusgruppstudie om bebisföräldrar på folkbiblioteket.
The purpose of this thesis is to investigate the functions of the public library for parents of infants and how they see the ideal library. The research questions are: How do parents of infants use the library and what are their experience of it? What opinions and wishes do parents of infants have regarding the library? How can library services be developed to better match the needs of the parents of infants? The theoretical approach is based on Marianne Andersson and Dorte Skot-Hansen?s model of the public library?s functions and the model of classification by Ellen-Merete Duvold and Gunnar Sæbø. To answer my research questions I have carried out three focus-group interviews with parents of infants. The study revealed that the public library functions as a cultural centre, a social centre, a knowledge centre and, to a certain extent, an information centre for the parents.
Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet
The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.
Den moderata rationalismen : Kommentarer, preciseringar och kritik av några begrepp och teser som framlagts av Laurence Bonjour i dennes In Defense of Pure Reason
The paper contains comment, clarification and criticism, even constructive criticism, of some theses that have been put forward by Laurence Bonjour in his In Defense of Pure Reason.It presents a concept of experience that deals with the relation between cognizer and object of experience that has a great similarity to that of Bonjour. Through analysis it is shown that the concept of a priori entails that Bonjour has two concepts of a priori, a narrow and a broad one. The narrow one is, in my own words: According to moderate rationalism a proposition p is a priori justified if and only if you apprehend that p must be true in every possible world. This doesn?t mean that Bonjour doesn?t believe in an epistemological, metaphysical and semantic realm.
Mysteriet med de spridda människobenen på Ajvide, Gotland : en studie om olika gravskick samt begravningsritualer under neolitikum
This essay includes an osteological analysis on the 1122 scattered human remains from The Pitted Ware culture site at Ajvide, Gotland. The scattered human remains have been found in the cultural layers, during archeological excavations at Ajvide between the years 1983-1987 and 1992-2009, where a burial ground was discovered. During the excavations, 85 skeletons graves were found, with complete and incomplete skeletons of 87 individuals. But aside from the graves, scattered human bones were discovered at The Pitted Ware culture site. One of the aims of the essay was to examine the bone material of the scattered human remains, and to determine whether this could possibly be a different type of burial custom than the skeletons graves.

Today Södra Skog?s assessments of timber potentials are mainly based on experience rate and subjective assumptions.
Ge dem en röst : Lärares uppfattningar om hur de skapar förutsättningar för elevers delaktighet i grundsärskolan.
The aim of this study is to examine how teachers enable students with intellectual disabilities to participate in their own learning journey. The study is based on qualitative methods and data collection has been done through five individual interviews in another European country. The interviews are analysed with a qualitative method inspired by Bryman (2011). The studies theoretical frame is founded on thoughts of Dewey (1997; 2002; 2004). The results of this study shows, among other things, that good relationship between adults in school and students are an important base for participation. To build a good relationship to the students, the teacher has to have good knowledge of each individual student and its disability.
Metodundersökning av tre metoder för kvävemätning i en arktisk äng : Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)
The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.
Är kolrika jordar en källa till fosforläckage? : en sammanställning av data från 130 åkerjordar
Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore,
the minerals used to produce the mineral phosphate is a non renewable resource.
There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils.
The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).
