The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

This essay aims to higlight the perception of achievement among politicians and directors in one of Malmö´s district. The questions higlight the success factors for goal attainment and how to legitimize goals. The success factors that are important are clarity regarding both the organisation, leadership and communication. To achieve that a pioneering leader who can motivate and establish their employees is needed. It is also important to create realistic goals to achieve legitimated goals..

This thesis, entitled The Headmaster and the Music, is based on interviews with four headmasters, who are all working in the Swedish compulsory school. The purpose is to investigate how they view music, both in general and as a school subject. Since the research on this topic is scarce, the study can be described as explorative.The result shows that the headmasters? personal experiences have an impact on the way they view music. Four different focus points on music in school have emerged from the material, and these represent the four very different views that each headmaster holds.

AbstractStormwater is defined as rain- and melted water. Ludvika kommun had little knowledgde about the stormwater that reaches a specific recipient Lyviken. Therefore they intended to do an research of the stormwater that leads down to Lyviken. The aim with this study was to assess the quality of the contents in the stormwater based on pH, conductivity, phosphorous, nitrogen, bacterias, oil and one sample that meassured the value of several methals. Since the population has increased for decades, the area of hard surfaces and asphalts areas also has increased. This can increase the pollutions that finally ends up in the recipient.

The study is aimed at investigating the Slovenian philosopher Slavoj ?i?eks theories ofthe ontology of the subject, the crisis of our modern society and his views on how theology,especially Christian theology, can provide the answer for the threats to our society.My main object is the article Descartes and the post-traumatic subject (2008)where ?i?ek elaborates thoughts about the subject and our capitalistic society. To be ableto grasp these thoughts in full I have undergone an investigation not only on the writingsof Slavoj ?i?ek, but also on the philosophers to whom he owe much of his theories,such as G.W.F. Hegel, Friedriech Schelling, Karl Marx and Jaques Lacan.In the study I have shown how the subject is, according to ?i?eks psychoanalytictheories, decentered.

Today, high-yielding leys of good quality are a must for Swedish dairy and beef enterprises if they are to become profitable. Thus, it is of interest to evaluate the quality of the recently released high-yielding Festulolium hybrids ((Festulolium braunii (K.Rich.) A.Camus). The aim of this project was to determine at what phenological stage three different Festulolium hybrids should be cut in order to get the highest nutritional value. The hybrids studied were Hykor, Perun and Paulita. In the study I also investigated if leaf proportion of the crop could be useful for predictions of the crop content of metabolizable energy. The cultivars were grown in plots within a variety trial with ryegrasses.

The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.

The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc & Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis wax varnish. The study is based on contemporary conservation theory and interpretation-based decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has retained its solubility properties and transparency over time.

Through qualitative interviews with five teachers from three schools, two public schools within the same school management and a Waldorf school, the purpose of this study is to find out teachers' views on the phenomenon of life skills in the lower classes in school. What is the subject, how do teachers work with life skills, and should it be seen as a separate subject or integrated in all school subjects?The results show that the definition of life skills is a term with many interpretations. Two concepts that can be seen as the common denominators in the educators' views on the subject, however is, social and emotional skills. This is something that educators believe develop self-awareness and empathy in children and sees that as important as learning other subjects.

The purpose of my essay is to see how teachers are working to integrate the two subjects Art and Swedish in their teaching, and to see how this integration is made. What do teachers think about subject-integration? What are the positive effects of it? Are there any difficulties involved? Do the teachers prioritize cooperation with other subjects?To answer my questions I have interviewed eight teachers, four of them in upper secondary school and four in lower secondary school. I have also studied literature about subject-integration and children?s learning, curriculum?s and syllabi in the subjects of Art and Swedish.The results of my study show that the interviewed teachers are positive when it comes to integrating Art and Swedish and other subjects.

Based on phenomenological hermeneutics and narrative theory the study explored how parents experience and create meaning when the child receives the diagnosis of autistic disorder. Interviews were conducted with eight parents and the analysis concerned both contents and form in their stories. The resulting aspects of the contents is presented in seven areas: stories about the time before the diagnosis, seeking help, receiving the diagnosis, the meaning of the diagnosis, coping, living with autism and stories about the future. The six resulting aspects of form included: chronology of the stories, creating order out of chaos, cultural norms, rewriting the story about the child, aspects of metaphors and changing perspective. The conclusion of the study is that the diagnosis serves as a way for the parents to transform experiences into a meaningful whole.

The purpose of this study is to show how some Swedish teachers in the grades four to six assess the subject of English and what impact the national tests have on teachers? way of looking at assessments and grades and how teachers are supposed to work with assessment and grading according to the curriculum and the education act. The method of this study has been interviews with principals, teachers and pupils to get as many perspectives of the subject as possible. It has contributed to an interesting content and the end result will be as fundamental as it can be. The findings of this study show that teachers teaching English in Sweden have a great responsibility because of the lack of subject priority and communication between themselves, the government and other authorities in the world of education.

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

Purpose/Aim: The purpose of this essay is to see how the media, through the newspaper, "Vi föräldrar?, produces family and parental roles, and to investigate how the image changed over time.Material/Method: The material consists of a number of selected texts from the years 1968, 1988 and 2008. The method used is a discourse analysis based on the three level model by Norman Fairclough. The three levels are the text, the discourse practise and the sociocultural practise. In this study two of the levels, text and sociocultural practise, are used in analysing the texts.Main results: Family and parenting in the texts from 1968 can be linked to the structural functionalist theory in which the core family is central and women and men are assigned to specific roles.
