Lärare och skolbibliotekarie ett udda par som bör dra jämnt. En studie i samarbete på en högstadieskola
This Masters thesis concerns collaboration between teachers and librarians. Three theoretical perspectives, profession, power and legitimacy, are used to analyse the results of written interviews with eight teachers and one librarian at a comprehensive school. We did not find evidence of any deeper collaboration between teachers and the librarian. The effects of profession had little impact on the relation although the involved parties seemed to appreciate differences in education and points of view. The teacher retains power over education and grades while the librarian holds sway over the physical library and the purchase of books and other media.
Konstruktion av turbinmodell för kaplanturbiner
Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.
"Man kommer inte särskilt långt om man sitter på sin lilla ö" : En studie om samverkan kring ungdomsarbetslöshet
The aim of this study was to examine the view that officials involved in youth unemployment have on the significance of collaboration between organizations working with unemployed youth. The study was based on nine qualitative interviews with officials from PES offices and from municipalities such as job coaches. The results were analyzed based on qualitative content analysis. The analysis led to two different themes: conditions and the individual. In the analysis two different theories were used, new institutionalism and Lipsky's theory about street-level bureaucrats.
Biogasanvändning vid Käppalaförbundets Reningsverk: ? en värdering av miljöeffekter
This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.
EU:s normativa makt inom miljöområdet : En fallstudie om EU:s roll i det globala klimatarbetet
Over the past twenty years, the cooperation within the European Union (EU) has strengthened and expanded with both more number of Member States and stronger influence on international politics. The unique character of the Union and its ability to enforce peace and humanitarian intervention has attracted attention in political science. This prominent position of the Union is perceived by many scholars who often hold this derived from the Union's influence in international relations. Various terms have been used to define the powers of the Union. The British researcher Ian Manners states that the unique identity of the Union in the international arena is formed by its normative power. An important policy area within the Union is the environmental cooperation.
Barnbokens karaktärer ur ett genusperspektiv : normativt eller normutmanande
The aim of this paper is to examine how gender roles are described in two children's books and compare the results against the curriculum Lgr11 's values. The compared books have different aims though one of the analyzed books claimed to go against the gender roles and the other one isn?t. The method of analysis is discourse analysis and deconstruction of the text by using Nikolajeva´s (2004) pattern for stereotype gender descriptions and Kåreland´s (2005) analysis of story actions based on gender representations in children's literature. The analysis of the texts shows that there are differences between how the two books characters are described depending on gender. What emerges is that in one of the books femininity is valued high but instead it lacks equality between the sexes, while in the second book the main characters are described as equal even though the other characters are described in a stereotypical way.
Religion för vem? : En genusanalys av hinduismen i läromedel
The aim of this study is to analyze Hinduism in upper secondary school textbooks using a gender-based perspective. The specific material used consists of four textbooks, whereof two are published prior to the curriculum Lgy 11 and two are published after Lgy 11. In order to analyze the textbooks the following methods are used: content analysis, picture analysis and comparative analysis. First, the contents and pictures of the textbooks are analyzed using theories on gender. After this analysis the results are compared to the relevant curriculum and its guidelines for the analyzed subject.
?Den seriösare heterosexuella mannen som har en homosexuell läggning.? : en studie om maskulinitet, manlig sexualitet & representation i tv-serien Queer as folk
Purpose/Aim: This study is an analysis of the view on masculinity, male sexuality and creation of identity with the television series Queer as folk as a base. The analysis is partly based on a semiotic analysis of the representation of masculinity and male sexuality from an episode of the chosen television series Queer as folk, and partly based on a thematic analysis of focus group discussions with young men with different sexualities.Material/Method: This study is based on focus group interviews and a semiotic and thematic analysis. The focus groups consisted of three men in three different groups and were chosen on the criteria of gender and sexuality. All groups were presented with an episode of the television series Queer as folk to see how they perceived masculinity and male sexuality. Their discussions were analyzed with a thematic analysis and the television series Queer as folk with a semiotic analysis.Main results: The three analyzed characters in Queer as folk showed different representations of masculinity and male sexuality.
?Religion? som diskursiv strategi. Diskurser kring kategorin religion i fyra offentliga debatter i Sverige
The thesis explores how the category religion is used discursively in Swedish public debates and in what way the discourses can be related to debate-positions. The thesis also exploresquestions of power and how social identities are negotiated: which identities are madepossible ? and encouraged ? by the discourse, and which are being excluded?The specific cases chosen are: (i) the election of Omar Mustafa as a substitute member of the governing board of the Social Democratic party in April 2013, (ii) the appointment of Elisabeth Svantesson as Minister of employment in September 2013, (iii) the debate concerning male circumcision (2011-2013), and, (iv) the debate about Jewish home education(2012-2013).The theoretical and methodological perspectives used in the thesis are discourse analysis and Pierre Bourdieu?s theory of social fields, usually interwoven together. Discourse analysis is mainly used to explore how the category of religion is attached to central binaries in the debates such as faith/politics, private/public, secularism/fundamentalism, etc., and also how chains of equivalences are established. Bourdieu?s theory of social fields is used tocontextualize the discourses in the specific debates and relate them to orthodox and heterodox debate-positions.
Design och konstruktion av laborationsutrustning till en kraftelektronikkurs
The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..
Självskadebeteende : En studie om identitet och självuppfattning
The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves? We want to examine in what way social relationships are important and how they function for individuals who harm themselves, both once they have started to harm themselves, and if the relationships in any part caused the cutting to begin with.Questions:How do individuals shape their identity based on self- harm? Which self-image do individuals have who self-harm? Is there anything in the person's previous social relationships that have caused them to begin to hurt themselves?Method:In this paper we have analyzed five autobiographies. We have used open coding from grounded theory as analytical method and subject positions based on discourse analysis.Theory:We have used the Cooley concepts looking glass self, Foucault's theory of power, Giddens' concept of ontological security and existential anxiety.Results and Analysis:We found six different categories that we thought were central. These were negative self-image, guilt, lack of family support, negative experiences of others' views, the protective identity as self- harmer and insecure social relationships in school.Conclusion:The self-harming is a very complex behavior.

At each political party conference, the leader for respectively party held their opening speech, a speech that was covered by the press. This essay deals with how the press covers these speeches. Analysing how the different speeches were covered by the press, some tendencies regarding how the press report could be visualised. In this comparison the ?quantitative content analysis? was used.
Unga identiteter i förändringens Portugal: En postkolonial analys av unga, universitetsutbildade portugisers identitet i relation till de forna kolonierna och de förändrade relationerna till dessa länder
A radical change is taking place in the world today: some former colonies are now booming economically while several former colonizers are suffering from economic crisis. Postcolonial theory states that old structures from the colonization are keeping the South poor and the North rich. Today there?s a shift in these structures as former colonizers Spain and Portugal are forced to ask for economical support from their former colonies.The colonial discourse separated white from black and depicted the population in the colonies as the absolute antithesis of the Europeans. In Portugal circulated also lusotropicalism, an ideology that claimed Portugal as absolutely free of racism, a statement with great influence in the postcolonial Portugal.On the basis of semi-structured focus groups I will in this paper do a discourse analysis of young, university educated Portuguese identity/ies in relation to the former colonies and the changing relations to these countries.
