Med andras ögon : En intervjustudie av åsikter och värderingar om effekter och produkter av det svenska jordbruket
The majority of the Swedish population were self-provided within agriculture a hundred years ago. Times do change and today the situation is the other way around - most of us live within city boundaries and only few work with farming and related agricultural businesses. One thing that has not changed though, is the need of supplies from Swedish agriculture.What do we think of those products? Are we even aware of the connection between us and agriculture? The Federation of Swedish Farmers, LRF (Lantbrukarnas riksförbund), started their project to strengthen the link between consumers and producers in 2008.This paper is part of the project and its aim is to investigate consumers' views and values upon the effects and products from Swedish agriculture.Opinions and values have been studied through interviews influenced by phenomenology. The results show that the informants in general had a positive approach and thinking concerning the products and effects from Swedish agriculture.
Läroboken svart på vitt : En diskursanalys av åtta samtida geografiböcker
ABSTRACTA Qualitative Discursive Analysis of Eight Contemporary Geography BooksTeacher Training with an Intercultural Profile 2006Author: Susanne LjunglöfTutor: Jan-Eric MattsonThe aim of this paper is to describe which discourses concerning the different continents problems, future and development that I can find in the descriptions of the continents in a number of contemporary geography books.The aim has been divided in four questions:- Which aspects of the continents problems are expressed in these geography books?- Which impressions concerning the continents development and future are expressed in these geography books?- Which conceptions about the population in the different continents are expressed in these geography books?- Which cultural reference creates these discourses?The method used for conducting this study is a text analytical method called general discourse analysis.My conclusions:- The different continents problems, development and future are described through entirely diverse discourses.- The reviewed geography books take their origin i a western perspective in their description of the different continents.- As a reader it is always important to be aware of the ethnocentric perspective that could be expressed.
Granproduktion på tallmarker! : är produktionen hållbar?
The aim of this report was to investigate the hypothesis that Norway spruce (Picea abies L. Karst), planted on poor ?Scots pine? stands will not have sustained growth during the whole rotation, due to water deficit in the closed stands. In order to investigate this hypothesis, data from 10 Norway spruce stands in southern-eastern Sweden were collected. In 10 plots in each stand, diameter and breast heights were measured on every tree.
Falun Gong i religionshistorisk kontext
Qigong was initiated by the Chinese government in the 1950´s as a domestic medical tradition to be included within a modern scientific framework. During the first decades it became popular among the élite. During the 70´s and 80´s scientific confirmation of the existence of qi contributed to its immense popularity among the population. Charismatic leaders with a traditional background were leading their groups in parks and the movement was booming. In 1992 Falun Gong was established by Li Hongzhi as qigong taken to a higher level.
Upplevelser av beslutsprocesser inom den kommunala hemtjänsten
The aim of this thesis is to examine the properties of the municipalities in Sweden that influence the choice of being a certified Fairtrade city. The independent variables which are used in the statistical analysis are municipal governance, local tax rate, whether there is an university and/or university college in the municipality, average income and higher education in the municipality. The variables are examined by logistic regression. Since there are no statistical data on ethical procurement, this exogenous variable isn?t included in the regression.
Analys av instyrning och rolldynamik
When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.
"Det som inte dödar stärker" : Tidsperspektivets betydelse för effekter av att känna empati
En tidigare studie har visat att negativa effekter av att känna empati är övervägande på kort sikt medan positiva effekter är övervägande på lång sikt, gällande psykiatripersonal. Med den aktuella studien avsågs att undersöka huruvida liknande tendenser finns hos en generell population. 253 högskolestudenter deltog, och i en mellangruppsdesign besvarade hälften en enkät belysande upplevelser på kort sikt medan den andra hälften besvarade en likadan enkät belysande upplevelser på lång sikt. Resultatet visade att empati har olika effekter beroende på tidsperspektivet även för människor generellt, i form av mer positiva effekter på lång sikt. Denna effekt återfanns bland såväl kvinnor som män, och bland yngre såväl som äldre.
Captr.net - Utveckling av iPhone-applikation och hemsida
Within the literature and film sciences there are clear models of storytelling and methods of creating a good story. In the game industry it's more difficult because the games are often non-linear, and games are a less established medium than the other two. With this study our purpose was to examine game developers and methods they used when creating a videogame, with focus on storytelling. Four interviews were made with representatives from four different videogame companies in Sweden. The information from the interviews was put in relation to theories regarding the structure of videogames and an established model for creating videogames.
Samhällets Sårbarhet för Klimatförändringarna
The effects of the climate changes are expected to generate several substantial direct and indirect consequences on both ecosystems and societies. It is the extent of the negative consequences that determents the vulnerability of the things or the ones exposed. The knowledge of the effects and consequences by a changing climate provides an opportunity to take measures to reduce the vulnerability.Our society?s vulnerability depends on how we choose to act out of the existing knowledge and what measures we choose to take. Karlstad municipality has good knowledge and perception of the increased flood risks the climate changes will generate and the probable consequences that most likely will follow. How the municipality decides to manage the flooding issue is not just affected by the will to mitigate the vulnerability but also by the vision to increase the number of citizens.
Ekonomistyrningens påverkan på MRP-implementering: en fallstudie av ASSA AB
The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.
HARR (THYMALLUS THYMALLUS) I VÄTTERBÄCKARNA : En studie om samband mellan bottenfauna och harrens förekomst
This thesis aimed to investigate how a rising sea level would affect the livable area of the island Fongafale, Tuvalu. Through the IPCC stabilization scenarios it was examined which areas of the island that would be affected by flooding. The local population?s perceptions of the effects of climate change were studied to see how the consequences of a world-wide problem such as global warming affect people's lives. The paper clarified the Tuvaluans place in the discussion of climate refugees, explained IPCC's work and described the results of previous studies concerning people in Fongafales perceptions and concerns about climate-related changes.
Hushållsavfall i vardagen : En komparativ studie av tre svenska kommuners plockanalyser
Undersökningar visar att elever har svårt att ta till sig evolutionsteorin och i stället väljer att förklara evolutionen med icke vetenskapliga argument. Till exempel väljer de att förklara fjällharens vita vinterpäls med att en vit päls gör att den syns sämre. Det här är ett exempel på att eleverna gärna förklarar evolutionen som behovsstyrd. En laboration utformades för att illustrera hur variation och urval ger evolution i en plantpopulation. Laborationen går ut på att eleverna under en tid studerar en population med plantor som utsätts för torka.
EU:s klimatpolitik - förhandlingsvägen till framgång
Eleven years after broking the Kyoto-protocol, the European Union still stands in the front line, combating climate change. How come the EU, with 27 diversified states, is able to integrate its members to what is widely considered the most progressive climate policy in the world? This thesis takes a closer look at the negotiations that have shaped EU climate policy. Using negotiation-models to categorize different aspects of EU climatenegotiations, several key-findings are presented. The thesis concludes that while EU entered the Kyoto-protocol with little to lose because of external factors like previous energy-reforms in key member countries, it had plenty to win in global influence and the satisfaction of an overwhelmingly Kyoto-positive public.
Reglering av veka strukturer med multipla sensorer
In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.
