Varför värdegrund? : En studie av skolans moraliska fundament
School and education are topics that are frequent in Swedish media. The intention of this essay has therefore been to investigate the image of teachers and their profession in Swedish daily press. The overall aim has been to analyze how teachers are portrayed in the debate that followed the TV-show Klass 9A, and by that find how the debate defines the concept of a good teacher. The representation that was found was then compared to earlier studies. The series was shown on Swedish television between January and March 2011.26 articles were chosen and the ambition was to have various perspectives represented, such as different voices and also papers from different areas of the country.
Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet
Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations were performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.
En jämförelse mellan vakuumisolering och traditionell isolering
The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.
Effektivisering av EPC projekt : Fallstudie Johnson Controls
In todays society the demand on companies to deliver better project management is crucial for them to survive. The higher demands from clients make older project management weak and unreliable. In the constructions sector more and more companies are created and the competition is higher than ever. The clients are aware of the higher competition in the construction sector. This has resulted that construction companies must now make their project management more efficient to create better projects and better relationship with clients. The purpose of this thesis arose from this problem in the construction sector.
Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med hjälp av UV-ljus och ozon
This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.
Mellan politik och funktion - En studie av öresundskomiteen som en politisk arena ur ett radikaldemokratiskt perspektiv.
The concept of the dynamic region has become a more prospering thought in the era of globalisation. This concerns in particular, cross border regions ? well-integrated territorial regions crossing more than one nation. In this paper I examine the development from a critical perspective and I map the democratic pitfalls of new territorial political constructions across national borders. The empirical analysis is a case report taken from the Öresund region, a cross border region between Sweden and Denmark.
Barns delaktighet och inflytande i den pedagogiska dokumentationen i förskolan
The purpose of this study is to find out what the educators idea of educational documentations in ratio to childrens inclusion and impact in pre-school are, together with the child's own perception of the concepts of documentation. We proceeded from the following issues: What are the significance of educational work according to the teachers? What is the teachers idea of a childs impact and inclusion in educational documentation? In what way do the children have influence over, and inclusion in educational documentation? What are the childrens feelings of the documentations? In order to find answers to our questions, we used qualitative examinations consisting of seven educators and seven children from various pre-schools in Stockholm, and thereby, we have analyzed our results. As our theoretical frame, we used ourselves of Vygotskijs and Säljö's sociocultural perspective that is about "progress and learning", which is achieved by interaction and cooperation in a social context. The result shows that the aim of educational documentation is to reveal the childs development and learning, and also to involve the parents by putting up documents on the wall.
Rekonditionering av IBC
This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation
Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.
?Av kvinnor, för kvinnor. Fy fan!? En kvalitativ studie av hur sex svenska folkbibliotek integrerar jämställdhetsaspekter i sin användarorienterade verksamhet.
This master?s thesis investigates how six Swedish public libraries integrate equality aspects in their user oriented activity. The theoretical starting point for the study is that Sweden is a part of a gender system characterized by gender separation and male superiority, as described by the Swedish historian Yvonne Hirdman and theories that argue that femininity and masculinity are social constructions. Another starting point is that the library sphere cannot be separated from the gender inequality in society. Since the library is part of a gender system that value individuals who are seen as males and separates men and women, some of the library users may be neglected.
INDUSTRIALISERING AV FLERBOSTADSHUS
The construction process which is used today while constructing residential buildings has for along time remained unchanged. Unfortunately the development process has gone away frombecoming industrialized and instead most of the work is done at the construction site. In thisrespect this is a worse alternative because the project outcome will be more expensive and theconstruction time will be longer. Skanska?s vision is to have a process which is more like the oneused in small residential buildings which is fully industrialized.The constructing process for residential building involves more parties and therefore it becomesmore complicated.
Arenans betydelse för en stad : En studie av en arenas tillförande av väde i platsmarknadsföring
AbstractThe purpose with this essay has been to gain a greater understanding and clarify how an arena can create value within place marketing and development of a place brand. This will be achieved through a description of which values an arena causes in the surrounding areas and an understanding of how these values can be interpreted through the place brand. We decided to base our study according to the following two questions:1. What are the underlying reasons why there has been such a big trend with arena project?2.
Jane Austens romaner på film och i litteraturhistoria; en uppsats om nutida tolkningar av en författares verk
The purpose of this study is to examine modern constructions of Jane Austens work in films and in books on history of literature. The theoretical framework contains sociology of literature, cultural studies and film theory. I compared Jane Austens books Emma, Pride and prejudice and Sense and sensibility with three film versions from recent years. In the books on history of literature I studied, I found three different attitudes towards history of literature, which also influenced the interpretation of Austens novels. The stories in Austens books and in the films are similar.
