In-store retail environment ? A study if placement of ecological products has an impact on sales and attitudes towards buying.
The purpose of this thesis is to investigate whether placement, using a special display, of ecological products, will have an effect on consumer buying behaviour and thereby sales of these products. When talking about sales we refer to the amount of ecological products that are being bought, habitual and unplanned, as a response due to the placement of the products in-store. To further elucidate the purpose, the thesis will focus on if the placement of the products itself will have an impact on the customers? attitude towards buying ecological products. A deductive approach was applied where we did a quantitative study using triangulation to receive data to reveal if the placement of ecological products had any effect on the sales of these products.
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.
Robotstyrning med metoden Sliding Mode Control
The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.
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.
Eu:s jordbrukspolitik sett ur perspektivet ekologisk hållbar utveckling i Sverige
The aim of this essay is to give the reader an idea of how the European agricultural policies have developed, in regard of sustainable development, since Sweden became a member in the union 1995. The main aspect that?s been investigated is the issues regarding sustainable development and how the issues regarding the ecological farming methods have been dealt with. My research questions are:- How has the European environment- and agricultural politics changed since Swedenjoined the union in 1995?- What consequences have the changes had for ecological farming?The answers to the stated questions are that there have been several treaties in the field of environmental development of the agricultural policy, starting with the Maastricht treaty and ends up with the European Action Plan for Organic Food and Farming.
Attityder och kunskaper kring hållbara matvanor
The Purpose of this study was to examine what knowledge and which attitudes there are about environmental friendly food in the society. To do so an essay were constructed and distributed to five different working places. Altogether there were 50 essays distributed and 43 were returned. The main result; the respondents think that it is important for people to learn how to consume food in a more environmentally friendly way. The majority of the respondents recognized the eco-label KRAV but the European eco-label and Demeter were not recognized in a less extent.
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.
Glasbruksvillan och jakten p? den f?rsvunna dekoren
This thesis aims to propose a plausible design and construction of the lost gable
pediments of the Glassworks Villa in F?glavik, anno 1875. Through a
combination of building inspections, photo analysis and 3D modeling, the
researcher utilizes the combined results to digitally recreate the decoration that
once adorned the gothic revival villa's gable, to serve as basis for its actual
reconstruction. The study further highlights the use of modern technological
tools, such as 3D modeling software, to further enhance the understanding of
historical architectural elements. The researcher also emphasizes the challenges
and considerations involved in preserving and reconstructing historical
architectural details for future conservation endeavors..
Tillämpning av UML : Hur och varför
In the end of the 80´s the area of system development moved into a new era. As a consequence many new methods and development models emerged which in many cases resulted in problems when choosing system development models and methods. As a result of these problems the today standardized modeling language UML (Unified Modeling Language) was created. UML is tailored to support many different types of projects. This is possible because of UML?s capacity to be adjusted and adapted to a specific company environment.The purpose of this bachelor thesis is to investigate how and why companies use UML and what experiences and opinions those who use UML have of using UML in practice.
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.
Modellering och simulering av hydraulik för användning i hardware-in-the-loop
Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.
