Religion och vetenskap : En studie om tematiken religion och vetenskap samt dess gränsländer i gymnasieläromedel
The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..
Teknik i förskolan : En studie om hur 4 - 5 åringars uppfattningar om material och dess egenskaper kan utvecklas genom en pedagogisk aktivitet
The purpose of this work is to investigate how 4-5 year olds perceptions of materials and material properties can be developed through an educational activity. The study is based on two interviews with eight children in that age category. The interviews were conducted before and after an activity where the children were first introduced to the subject by the tale of The three little pigs (Harris, 2009) and then given the opportunity to explore various materials related to the book. The kids got to experiment and explore how water affected materials and to compare different materials properties. The children were also attracted to build and create the material that was offered during the activity.
Miljöarbete i förskoleklass : Jämförande studie om hur pedagoger integrerar miljöarbete i verksamheten och barnens kännedom om återvinning
The purpose of this study is to investigate what knowledge children in preschool have about recycling, and to examine how teachers work with environmental efforts to increase children's understanding of environment and sustainable development. And if there is differs between the two preschool classes, one of which has a environmental profile. The study is based on qualitative semi-structured interview methods of teachers and children, and observation of the children during a sorting exercise with a number of garbage objects. The result shows that teachers in the environment profiled preschool spend more time per week on work related to environmental and natural issues and worked more thematic.

Modeller för utvärdering av set-up för återvinning av lastlister inom IKEA
Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.
Allergifritt boende genom val av invändiga ytmaterial
The number of people of getting allergic symptoms is increasing and the reasons are considered to be many. The human have changed their habits and spend more time indoor. In combination with new building technologies where denser housing constructions and new materials this causes bad indoor climate contributes to a higher occurrence of allergiesThere are several courses of action to deal with this problem. One action is by choosing allergy-free interior surface materials. An allergy-free material emits low concentrations of harmful substances resulting in a great indoor air quality.

Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering
This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention Reuse Recycling Energy recoveryLandfill The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

Avfallsfraktioner i Sveriges hamnar
Varje år ökar avfallsmängden och användningen av naturens resurser vilket gör att återvinning blir en viktig del för ett hållbart samhälle. Årligen dumpas mer än 6,4 miljoner ton plast i haven från fartyg. Den 1 januari 2013 skärptes regelverket MARPOL för att minska mängden avfall som slängs i havet. Mot denna bakgrund har syftet med studien varit att undersöka hur motivationen att sortera kan påverkas av antalet avfallsfraktioner i hamnarna. En kvalitativ metod med sju intervjuer har använts.

Barns pedagogiska material : En kvalitativ studie om barns användning av det pedagogiska materialet som finns på fem förskolor och om sex pedagogers tankar kring placeringen av det pedagogiska materialet
?Childs pedagogic material ? A qualitative study of child?s use of pedagogic materials available at five nursery schools and about their teachers thoughts about the display of the pedagogic material?In the nursery preschool the environment and the educational materials have always had a central place. That's why it has been chosen to study and observe five preschools and interview sex teachers, in an attempt to understand the teachers thought about the choice of material and the choices of material that the children used. The reason I do this is to see what the underlying idea about the materials the children use is, and why educators choose to make certain materials visible. The purpose of this study is to examine the educational materials that are used to stimulate children´s learning and examine what determines the choice of educational materials.
Demokratiteoretisk analys av läromedel i Samhällskunskap : En kvalitativ studie om det demokratiteoretiska innehållet i läromedel för Samhällskunskap 1a1 och 1b under GY-2011
This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.
Kvalitetssäkring av hushållsnära avloppsfraktioner : vad kräver livsmedelsbranschen?
On-site sewage systems are common on the countryside of Sweden with approximately one million on-site systems installed. Due to insufficient function, these contribute significantly to the total discharge of phosphorus to rivers and lakes, causing eutrophication.
In order to reduce eutrophication and to fulfil one of the environmental quality objectives, the decision was taken by the Swedish Government in 2005 that 60 % of phosphorous in sewage sludge is to be recycled to arable land before 2015. To make recycling a reality, new solutions have to be found. Federation of Swedish Farmers (LRF) takes an active interest in this issue and has initiated this study.
One problem is that the food industry is sceptical towards recirculation due to the risks that products from sewage systems may contain pathogens, heavy metals and unwanted chemical compounds, e.g.
Att återvinna ett fartyg : En undersökning av en miljövänlig fartygsåtervinningsindustri
Syftet med förelagda undersökning var att karlägga de krav som ställs vid återvinning av han-delsfartyg i de nya regelverk som antagits av IMO och EU med målet att åstadkomma en miljövänlig fartygsåtervinningsindustri. Fokus har legat på de krav som de aktuella regel-verken ställer på fartygsägare och fartygsåtervinningsanläggningar, främst beträffande hantering och bortskaffning av de miljöfarliga material som finns ombord på fartyg. Med dessa krav som utgångspunkt har det redogjorts för hur ett återvinningsförfarande organiseras för att uppfylla de miljökrav som regelverken ställer.Resultatet av undersökningen pekar på att det med dagens teknik och kunskap i allra högsta grad är möjligt att åstadkomma miljövänlig återvinning av handelsfartyg. De problem och utmaningar som resultatet pekar på ligger på ett annat plan än det rent praktiska, bland annat lyfts den långsamma process som implementering av regelverk är fram som en utmaning för fartygsåtervinningsindustrin.Slutdiskussionen handlar till största delen om implementering av lagstiftningen, men också om hanteringen av fartyget och de material som finns ombord, samt om definitionsfrågor rörande ägendeskap. Vidare diskuteras rollen för andra aktörer inom sjöfartsnäringen och de åtgärder som dessa skulle kunna vidta för att åstadkomma en miljövänlig fartygsåtervinning innan de aktuella regelverken träder i kraft och blir bindande.
