EU:s omställning till en hållbar jordbruksnäring

Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

The Legal Significance of Sustainable Development in EC Law

In June 2006 the Council of the European Union agreed on the review of the EU sustainable development strategy. This renewed strategy voices a commitment to sustainable development that includes a diverse list of safeguarded interests. Sustainability is to be attained in the spheres of democracy, solidarity, the rule of law, gender equality and at the same time it should promote a dynamic economy. Given this multifunctional application of sustainable development, curiosity may soon give rise to questions such as; What is the legal significance of the concept? Is it to be considered a general principle of Community law? And can it be used as an instrument in adjudication and legal reasoning? Anyone who looks deeper into the concept of sustainable development is soon to find a labyrinthine complex of ideas, expressions and opinions.

Tolkning av dubbelbeskattningsavtal : mot bakgrund av OECD:s föreslagna ändringar i kommentarerna till artikel 5.1 i modellavtalet

In recent decades, demands has emerged that the companies shall take a greater social responsibility for the impact that they have on their environment and that this impact shall be reported, which is known as Sustainability Reporting. The Sustainability Report is based on a number of general principles that ensure the content and the quality of the Sustainability Report. One of these principles is the principle of completeness. In the research, this principle seems to have been interpreted in terms of number of reported aspects and indicators, which can be a limited view where only the existence of the aspects and indicators is observed. By including the degree of the reporting in terms of full, partial and no reporting as well as a comparison between the real and the alleged reporting, our intention is to extend the principle of completeness and to develop a tool that we also apply through an empirical survey in a particular area.

Användbarhetens roll i de mobila webbshopparna

This paper reports a study on the usability of e-commerce accessed through smartphones. There is much research in the usability of mobile interfaces and many sets of design patterns have been created but a few studies are available for specific domains, and in this report we focus on mobile e-commerce. In this study a framework is developed for how to design mobile e-commerce interfaces with a high degree of usability. Furthermore, the study also contributes a method to how other specific domain can develop a framework with general standards to work from when creating a web interface. By examining two sets of design principles and 14 design patterns, we evaluate which ones are critical in the design of a mobile e-commerce interface for achieving a high degree of usability.

Didaktiska arter

The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. Easily recognizable indicator species could improve dialogue between the scientific community, administrative authorities and the general public. Such species could be used in education systems, associations or in information campaigns. Therefore, I have chosen to refer to these species as didactical species.

Fullständighetsprincipen i hållbarhetsredovisningen : En fördjupning samt en tillämpning

Uthållig estetik i landskapet - om att synliggöra sitt förhållningssätt till hållbarhet : Sustainable landscape aesthetics - to demonstrate ones attitude towards sustainability

Abstract In my work, I have tried to define and clarify the conception of sustainability seen from my perspective as a landscape architect. With a basis in literature studies, I have analysed and commented on different applications, contents and meanings of sustainability and endurance. This compilation is based on how a number of writers, researchers and authorities consider the importance of integrating ecological, social and economic aspects of sustainability in city planning. My perspective has mainly been founded on the anthologies and compilations from the 80´s and 90´s where Per G. Berg and Björn Malbert acted as editors.

Koldioxidlagring - realitet eller utopi? : En komparativ fallstudie med syfte att undersöka potentialen för koldioxidlagring i geologiska formationer och biologiska sänkor och dess förmåga att bidra till hållbar utveckling

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

Illustrerad narrativ

Konsten att berätta historier med bilder och illustrationer är något som har funnits i flera tusen år. Detta kandidatarbete undersöker ämnet illustrerad narrativ och redogör olika aspekter och principer som är avgörande för att man ska kunna förmedla ett budskap med hjälp av illustrationer. Idag förknippas illustrerad narrativ framför allt med serietidningar, bilderböcker och grafiska romaner som berättar en narration i form av en serie av bilder. Under den teoretiska delen av arbetet har jag först gått igenom illustrerat narrativs historia och sedan redovisat principer för det moderna illustrerat narrativet. Jag har också forskat kring bildens kommunikativa värde och samspelet mellan bild och text.

Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?

Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used. The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.

Krig, mäktiga kungar samt en och annan "påsmetad" notis om kvinnor : En genusstudie av läromedel i historia

This study revolves around calculating the extent of appearance of both anonymously and named men and women as well as determining whether or not Yvonne Hirdman?s gender theory is applicable on two versions of a Swedish educational history textbook called Epos: historia: för gymnasieskolans kurs A (2008) and Epos [historia] 1b (2012), published for two different curriculum. Our qualitative investigation of two parts of the book?s content proves that the two principles of gender system are present in both books, although to a lesser extent in the latter version. Calculating the material, results have shown that anonymous men and women are almost equally presented in Epos 2012, which is not the case in the 2008 version.

En jämförelse mellan två släktarkiv : Ordnandet och förtecknandet av det Gardtmanska och det Hamnströmska släktarkivet

For my advanced degree in archival science, I have organised and catalogued two family archives; man Family Archives ("Gardtmanska släktarkivet") and the Hamnström Family Archives ("Hamnströmska säk- tarkivet"). Though both could be labelled "family archives", there were many differences between the two. The Gardtman Family Archives contained the records of several family members from a period of several centuries, spanning from the early 17th century, to the early 20th century. It was by far the larger of the two archives. A substantial part of the records consisted of documents regarding various agricultural estates the family had owned or been involved with in one way or another.

BIM i produktionen vid väg- och anläggningsprojekt

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
