Att undervisa med didaktisk teori : en diskursanalys av grundskolans kursplaner för historia och religionskunskap
The aim of this exam is about possibility to position a didactical theory of Curriculum for compulsory school, preschool class and the leisure-time centre 2011 (Lgr11). I use Michael Foucault?s discourse analysis to study the syllabuses for social sciences subjects History and Religion. The main theme is to seek what kind of world does these two social study subjects construct for students in high school. The point of using Foucault?s discourse is to seek specific knowledge and words which is used for power positioning.
Potential för värmeåtervinning från mjölkkylanläggningar
The present climate discussion has made energy efficiency an interesting topic. Saving energy does
not only help the climate but also saves money for the energy consumer.
The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two
milk farms, one with voluntary milking system, VMS, and the other with conventional milking system
was used to measure interesting temperatures and electricity consumptions. The numbers were used
both to do theoretical calculations and to construct a SIMULINK model.
To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using
a reference farm with different combinations of heat recovery and pre cooling. The farm was
assumed to keep a dwelling house with the annual heat consumption 18165 kWh.
Fotografisk diagnostik av Molar Incisor Hypomineralization: Test av validitet och reliabilitet
Molar Incisor Hypomineralization definieras som ett specifikt tillstånd orsakat av störningar i den tidiga fasen av emaljbildning av en eller flera permanenta första molarer med eller utan involvering av permanenta incisiver. Tidigare studier har visat att standardiserad intraoral fotograferingsteknik kan vara användbar för epidemiologiska studier av emaljdefekter. Denna studies syfte var att utveckla och utvärdera en fotografisk klassificering av allvarlighetsgraden av Molar Incisor Hypomineralization genom att studera metodens validitet och reliabilitet. 164, 10-12 åriga svenska barn granskades fotografiskt avseende prevalensen av Molar Incisor Hypomineralization. Först granskades endast första molarens ocklusalyta, därefter ocklusal- och buckalyta.
Kim Jong Il - Docka eller dockmakare?
This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..
Teknisk undersökning av stafflimåleri ? Med fokus på två dörröverstycken från Röhsska museet
This bachelor thesis is a study in the analysis of paintings with focus on the technical exami-nation within the framework of ATSR. ATSR is a methodology based on an interdisciplinary study with the aim of putting the object in its context.The study is based on questions concerning which information the object can give, how we access this information and how it can be put in a larger context. My thesis contains three major parts. First a short overview of methods of analysis used in this form of investigation is presented. This is followed by two case studies which exemplify the technical investigation.
Direktsamplande digital transciever
Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.
Naturhänsynen i FSC-standarden : vetenskap eller gissningar?
The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.
Problembilder av ungdomars politiska utanförskap - En studie av projektet ?Demokrati för alla?
Aims: The aim of this study is to describe how youth?s political exclusion is constructed as asocial problem. This is done through a study of a project which aim is to engage young peoplein politics.Method and theory: By interviewing the project?s manager and developer as well as eightparticipating young people different constructions of the problem of youth political exclusionhas been analyzed using the social constructionist perspective on social problems.Findings: The dominant perspective found in the empirical material includes framing youngpeople?s lack of political knowledge and self-confidence as the reason for their politicalexclusion. Even though the Youth Board (ungdomsstyrelsen) in Sweden officially views allyoung people as a resource, when youth politics are implemented through projects, this is notthe view that young people meet.
Piotroski ur ett riskperspektiv : En empirisk studie av 3- samt 4-faktors CAPM
An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.
Sekretessavtal : Kan ett sekretessavtal i kommersiella förhållanden som gäller för all evig tid jämkas med stöd av 36 § avtalslagen?
When a company is part of an agreement there is a risk that one of the collaborators pursues similar business and takes up competition with the partner or chooses to reveal information about their partner to other parties. To avoid this, companies establish a confidentiality agreement that prohibits the parties to reveal any information. Confidentiality agreements that are eternal have become more common in Swedish contract law in commercial relations. As a result, disputes between collaborators have occurred regarding the unreasonable length and validity of the agreement at a later stage.When a confidentiality agreement is considered to be unreasonable, 36 § of the Swedish contract law (AvtL) can be applicable. The paragraph deals with the legitimacy and the opportunities of re-adjustment of the unreasonable contract.
Identitetsskapande på Internet : En kvalitativ studie om det sociala nätverket Facebook
As computerized communication and the Internet have evolved, the possibility to express and affirm one?s identity in new ways has also been created. Facebook, which has taken a leading role among the social fora on the Internet and succeeded worldwide, is my choice of study due to the number of people that actively choose to present themselves on it. The purpose of this thesis is to study the identity construction on Facebook through the activities a member partakes in, as well as how the presentation of oneself is written and if it is a result of a self-reflective process of the individual.The rationale for the qualitative study has been personal interviews in order to get an insight into how the individuals use and present themselves on Facebook and - in the interaction with others ? how they construct their own identity. My hypothesis has been that we, in the interaction with others, have a great possibility to create and understand our own identities. The study results show that identity formation is a constant process and that it is indeed a self-reflective project.
Konstruktionen av företagare som diskursiva subjekt : en diskursanalytisk studie av hur kvinnor och män representeras som företagare i tidningen Eget Företag
Given the possibility that the world, as we know it, is a consequence of human interaction and verbal communication our understanding of the world can be seen as contingent rather than essentially given. Conceptions such as "entrepreneur", "woman" and "man" can then be understood as socially constructed subjects. Departing from poststructural and social constructionist perspectives I will examine medial representation of women and men as entrepreneurs. My main purpose is to examine how the entrepreneur is constructed as a discursive subject in the journal Eget Företag. Drawing upon Ernesto Laclau´s and Chantal Mouffe´s Discourse Theory and the poststructuralist feminist theoretical perspective of Judith Butler I will discuss both the construction of the entrepreneur as well as the more explicit question; is gender significant for the construction of the entrepreneur and entrepreneurship in Eget Företag? In this study I come to the conclusion that the discourse of entrepreneurship, as well as the journalistic discourse, draws upon discourses of femininity and masculinity but also upon discourses of ethnicity.
Kundklubbar som en försäljningskanal - en studie om kundklubbar kan användas av Bergsala AB som en försäljningskanal
The purpose of this thesis is to explore whether male kindergarten teachers perceive additional expectations from their surroundings (such as co-workers and parents). Furthermore, we aim to understand and explain how these expectations are related to gender norms and hierarchies in society, that is social constructions concerning what men and women should do and be like. In addition, the thesis aspire to understand and explain how these constructions relate to more specific social constructions about sexual molestations in kindergarten contexts and explore how these discourses influence male kindergarten teachers in their work including which strategies they use in order to cope with them.How do male kindergarten teachers perceive additional expectations from their surroundings?How do male kindergarten teachers perceive the effects and consequences of the social constructions about sexual molestations in kindergarten contexts? Do they use coping strategies in order to attend to the expectations projected on them, and if so, what kind of strategies? The thesis is based on a phenomenological approach and conducted through interviews with six male kindergarten teachers. The interviews were directed with an interview guide in hand while allowing for spontaneous input from the interviewee.
De tre civilisationernas kontinent - En studie om Sydamerikas civilisationer i en globaliserad värld
In this thesis I analyse civilizations in South America. I construct civilizationalnarratives through the method of emplotment, to build a historic continuity, whichI subsequently connect to the theoretical framework. The theory emphasise that,when confronted with globalization and free market capitalism, civilizationsembark on different strategies to challenge the power of transnational marketforces. I find that South America is a polarised continent, and is divergingconcerning the relationship towards the USA and free trade agreements. On thesame time the issues that concern the social movements are not being reproducedin a significant matter at state level.
Staden mellan visionerna och asfalten: En studie av politiska idéer och visioner om staden ur ett rumsligt perspektiv
Urban planning is not only a matter of architectural trends; it is first and foremost political. This thesis seeks to understand the links between political ideas and visions for the city and the physical structure of the city. The study aims to construct a model to help understand these links, a helpful tool in analysing a city, focusing on the one hand at the physical structure of what I call "The City as a Welfare Provider" and on the other hand at "The City as a Growth Engine". It also sets out to test this model in an empirical study of Stockholm and the soon-to-be built district of Norra Station in the same city.The analysis shows that Stockholm has ambitions to be a welfare provider to its citizens, but have also adopted to a discourse of interurban competition which stresses the importance for the city to enhance economical growth. What is interesting is that the physical structures promoted in the planning documents of Stockholm are nearly exclusively those associated with the model of "The City as a Growth Engine"..
