Biologiska bekämpningsmetoder i hemträdgården :

Biological pest management is defined as control of pests using their natural enemies. This method has been used in Sweden since the 1970´s and it has been developed ever since. Biological pest management is today relatively common among commercial growers but there are good possibilities to apply this method in the home gardens as well. The aim with this thesis is to compile a report from both the companies that are marketing the products and the home gardener´s point of view. This should give a better understanding of the market and how it could be improved. We will give examples of products that represent the different kinds of organisms that are being used in biological pest management. Our hope is that this will be an introduction to all interested in biological pest management. The legislations regarding registration of organisms are still a matter of discussion and are causing problems to producers, distributors and the market in general. Why isn´t biological pest management more common in the home garden? The main reason appears to be the lack of knowledge in the subject. What are the benefits using biological pest management when it requires so much knowledge and it´s more expensive than conventional pest management? With the environmental problems we face today, we hope that every single gardener has an interest in developing an environment as clean as possible, even if only in one's own backyard..

Riktvärden för förorenad mark : En undersökning av hur riktvärden för förorenad mark har förändrats gentemot tidigare riktvärden samt hur de påverkas av variationer i geologiska och hydrogeologiska parametrar

Risk assessment is made to determine risks with contaminated areas and to determine which treatment the area requires. In Sweden, risk assessment is divided into three levels: risk analysis, facilitated risk assessment and detailed risk assessment. In detailed risk assessment site-specific guideline values are developed to compare with values of contaminants that are measured in the area.Site-specific guideline values vary with geological and hydrogeological parameters. The purpose of this report is to examine which of these parameters that affect the guideline values. The examination was done using a calculating program for consideration from the Swedish Environmental Protection Agency from the year of 1997.

Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Är demokratin i förändring? : En analys av demokratibegreppet i läroböcker i samhällskunskap för åk 4-6

The purpose of this study is to determine whether or not there has been a change in the use of democratic values in textbooks in social science for classes 4-6. The focus lies on democratic values from two different theoretical perspectives, Dahl?s theory of democracy and Habermas deliberative democracy. The method used is a text analysis based on a model made by Lennart Hellspong. The material we?ve analysed consists of four textbooks in social science from different decades, with a range from 1981 until today.

Vad är hållbarhetsredovisning? : En kartläggande litteraturstudie

Företag som upprättar så kallade hållbarhetsredovisningar har blivit allt vanligare. Dock råder det inom forskningen på området en oenighet om vad hållbarhetsredovisning egentligen är. En mängd olika begrepp används om vartannat och några klara definitioner finns inte fastlagda. Syftet med denna studie är därför att göra en kartläggning av de olika begrepp som används inom den globala, akademiska hållbarhetsredovisningslitteraturen för att utreda innebörden av dessa begrepp samt för att utreda hur dessa begrepp förhåller sig till varandra. Studien genomförs med hjälp av en litteraturstudie där 12 artiklar väljs ut genom ett intensitetsurval och sedan analyseras och jämförs med varandra.

Interaktioner inom kluster - fallet Mjärdevi Science Park

Bakgrund: Klusterbegreppet introducerades under 1900-talet, men fenomenet erkändes redan under tidigt 1900-tal. Trots att marknaderna idag blir mer globaliserade, är klusterbegreppet fortfarande aktuellt. Som exempel på områden som kännetecknas av starka länkar mellan företagen kan Silicon Valley och Sophia-Antipolis nämnas, även kända som ?Industriella Hollywoods?.Syfte: Syftet med denna uppsats är att analysera interaktioner mellan aktörer inom ett lokalt ?Industriellt Hollywood? ? Mjärdevi Science Park. Hur förhåller sig aktörerna till fördelar med att befinna sig inom ett närområde, i hur stor utsträckning utnyttjas dessa agglomerationsmöjligheter och varför?Metod: Denna studie är baserad på djupintervjuer med sexton företagsrepresentanter från Mjärdevi Science Park och en professor från Linköpings Universitet.Resultat: Aktörerna verkar vara medvetna om vilka agglomerationsfördelar som föreligger, dock utnyttjas dessa inte i någon större utsträckning.

Är objektiva moraliska värden möjliga utan Gud? : en teoriprövning av Moralens Landskap

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.
