Sol, jord och vatten. : Barns tankar om den ekologiska processen
Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.
Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten
In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.
Tar vi vårt ansvar? En granskning av Sveriges politik för global utveckling
This thesis deals with the theories of ecological and environmental justice and applies them onto Swedish politics. Confronting the divide in the literature between anthropocentric and ecocentric perspectives, its aim is to seek points of agreement within this important field of environmental politics. In the theoretical discussion, definitions are made of the concepts sustainability, justice and responsibility. These definitions try to link ecological and environmental justice arguments with a focus on the global level.The object of analysis is the former Swedish governments? bill ?Common responsibility: Swedish politics for global development? which was accepted in 2003.
För den goda sakens eller smakens skull?: En studie om vad som driver konsumenter i valet av ekologiskt vin
Concerns for the environment and our impact on it are becoming more prevalant; however, we rarely act accordingly. Consumers mainly choose products based on perceived personal benefits despite the environmental motives that increasingly affect them. The purpose of this thesis is to identify the major drivers behind the purchase of ecological wine. A quantitative study was conducted, using Theory of Planned Behavior (TPB) as an initial starting point. The subsequent model was then completed with three variables: environmental concern, feelings and word-of-mouth.
Avvägning mellan ordersärkostnad och lagerhållningskostnad i processindustrin
Lean Production is used by many manufacturing companies. Companies in process industries do not use Lean Production to the same extent today. This is part of the report's issue to explore how Lean Production can be applied to a company in the process industries.The investigated company is a processing company that manufactures various types of foil. The company wishes to streamline its production and has therefore asked the authors to examine if Lean Production can offer the company improvements in their production. Lean Production value stream mapping tool has been selected to identify and analyze the current state of two of its products in production.
Eu:s jordbrukspolitik sett ur perspektivet ekologisk hållbar utveckling i Sverige

Utvärdering av ett optimeringsprogram för produktionsplanering.
The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .
Grönstrukturens dilemman i fysisk planering : Hur fungerar målstyrningen av grönstrukturen i praktiken?
To reach an Ecological Sustainable Development, Sweden has established environmental quality objectives. Green spaces are attractive for exploitation and in Sweden the access to large jointly green spaces has decreased, which has impact on humans recreation and the biodiversity. The economic aspect has great impact on the planning process which gives indications that the environmental objective may collide with other sector goals within the municipality. The thesis overall aim is to see how the management by objectives for the green spaces implements and how the green spaces is handled in the planning process in a specific case. The thesis builds on a content analysis, strategic interviews and a case study.
Ekologisk gestaltning : en utvärdering av hur landskapsarkitektur påverkas av ett ekologiskt förhållningssätt
This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition.
These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.
Ekologiska fotavtryck för koldioxidutsläpp för Stockholms län, Norrbottens län och Stockholms läns landsting : En kritisk metodgranskning baserad på kvantitativa data
Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.
Naturvärden i en värmländsk bruksskog : en skogshistorisk studie av Åbengtshöjden/Bogranghöjden
In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite.
The aim of the study is to interpret the history of the forest in the area, i. e.
Motpol eller legitimeringskälla? - en studie av användningen av hållbarhetsbegreppet inom Malmö Stads fysiska planering
Sustainable development and sustainability is nowadays expected to be integratedin modern city planning and permeate the entire planning process. At the sametime, sustainable development has an inherent vagueness, leading to a greatdiversity of interpretations of the meaning of this concept. In this thesis strongsustainability and ecological modernization are used as two different interpretationsof sustainable development. Using these two interpretations, an analysis of thecurrent use of the concept of sustainability within the city planning of Malmö isperformed. The analysis shows that the interpretation of sustainable development inthe city of Malmö can be deduced to ecological modernization and thatsustainability is looked upon as one way to improve the attractiveness of the city.Investments to increase ecological and social sustainability must be legitimized asleading to a potential increase in economical sustainability (growth) and the focusof increasing the sustainability in the city has shifted from ecological aspects toeconomical aspects.
Utveckling av en ny tillverkningslina
This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.
