En ?vergiven torpmilj?. Materiella och immateriella l?mningar fr?n torpen kring Brunnslid i Kinneveds socken, V?sterg?tland.

This essay presents an investigation of the ruins of an assembly of crofts in a rural area in the south of Sweden, outside the town Falk?ping. Using literary sources and intangible sources, and then combine them with the information found by investigation of the physical remains of the crofts, the essay attempts to capture the life and the living conditions of the crofters. The investigation is focusing on the period between the nighteenth century and the first decades of the twentieth century, and looks into the the living conditions according to, for example, the buildings, the orientation in the landscape, demografical changes, the transformation of the area over years and how the crofters were affected by powerty. The investigation shows that the crofters in many ways were in vulnerable and exposed positions, powerty summarized as a lack of freedom ? concerning economical, political and social dimensions.

Kommunikativ maktförskjutning? Legitimitetsskapande kommunikation i kölvattnet av ett massmedialt uppmärksammat omhändertagande

Citizens are in need of information to form an opinion about how society works. As a reviewer of the Public power the media plays an important role in a democratic society. The communicative power shift appears in contemporary media landscape, where technology offers great opportunities for actors to use their own channels to communicate their own image and thereby influencing power over the agenda. Alongside this, the number of communicators is increasing which makes power of resources affects the communicative whole picture. The study is based on a media profile case of the described assault and looks at what can happen strategic communicative at a police department when journalism offers a negative image.

"Man vill ju se bra ut" : En kvalitativ studie om ungdomars syn på sociala medier

This thesis examines young people's thoughts about their presence on social media. With asocial constructive approach the study focused on how young people think and act on socialmedia in relation to constructions of gender and normality. The analysis is based on fourgroup interviews with 13-year old boys and girls. The theoretical approach is based partly onsocial constructionism where discourses and ideas of normality are identified and analyzed.Erving Goffman's theory of social interaction was central to illustrate how young peoplepresents themselves based on the prevailing discourses. It is clear that they adjust theirrepresentations of themselves depending on the context.

MON En mittpunkt i periferin

This thesis takes its starting point in the humanistic cultural-geographical concept of place, with the aim of achieving a greater understanding of what constitutes the place Mon today. Mon is located in the northwestern part of Dalsland. Until 1879, the area was described as outlying land, but with the extension of the railway between V?nern and the Norwegian border, Mon's station community emerged. In the mid-20th century, all activities in Mon were phased out, and since then, the place has been inhabited by only about 10 year-round residents.

Våtmarker för näringsretention i Lillån : var bör de ligga och vilken effekt kan vi förvänta

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

En obruten fjällmiljö och konflikten med vindkraften : En studie om rumsliga landskapspreferenser och vindkraftens påverkan på de svenska fjällen

De svenska fjällen skyddas i dagsläget av miljömålet Storslagen fjällmiljö, ett mål som ämnar bevara fjällens ursprunglighet och därmed skydda dem mot ingrepp. Den svenska regeringen har även inrättat 13 områden klassade som obruten fjällmiljö, områden vars natur- och kulturvärden ska värnas om och som, i så stor utsträckning som möjligt, ska hållas orörda. Båda dessa skyddsformer hotas nu av de planer som finns på att bygga ut vindkraften i landet. I denna studie undersöks den visuella påverkan som finns från dagens vindkraftverk samt den ökade visuella påverkan som genom fattade beslut är på väg. Metoden för studien är en rumslig GIS-analys som undersöker hur stora områden som vindkraften påverkar visuellt.

Margin of Appreciation : en kulturrelativistisk doktrin?

With the collapse of the Soviet Union and the 9/11 attacks, the landscape of the freedom of religion has changed. The issues now facing freedom of religion varies greatly from the issues that the drafters of the universal declaration of human rights faced after World War II.In the light of the new issues that States face in the intersection of religion and societal interest, scholars have criticized the European Court of Human Rights to give too much leeway to the States in determining how the human rights should be implemented, by using the doctrine of margin of appreciation. Critics of the margin of appreciation claim that it is based on culture relativism and that the doctrine undermines the universality of the human rights. In order to decide if the margin of appreciation has indeed led to a relativization of the human rights I compared it to the jurisprudence of the UN Human Rights Committee and its use of the Syracusa principles. My conclusion is that the jurisprudence of the European Court of Human Rights cannot be considered to be based on culture relativism.

Den Digitala teknikens påverkan på resebranschen och dess marknadsföring

The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.

Green-urban balance : a proposal for balancing green area preservation and urban development in the city of Uppsala

Rapid urbanization causes competition over land use between green area preservation and urban development in cities and greatly affects ecosystems as well as human well-being. This conflict is significant all around the world as many cities are now replacing existing green areas with new developments. The area around Dag Hammarskjöld's väg in Uppsala is currently experiencing the same conflict, as the need that the city has for new housing represents a threat for the many valuable green areas that are in the site. The purpose of this project was to understand how the need of urban development and the preservation of green areas could be balanced. This understanding would thereafter be used to make a design proposal for the area around Dag Hammarskjöld's väg.

Trädens betydelse för gatan :

?The trees importance to the street? discusses just that, the trees importance to the street. The purpose of this paper has been to examine what influence the trees have on streets. By writing about good examples of how trees can add good qualities to a street I wish to inspire to more use of trees in future city-planning. I have examined three streets in Malmö and three streets in Berlin and analyzed the trees influences there through the help of literature by three authors: Great Streets (1993) and The Boulevard Book (2002) by Allan B. Jacobs, Trees in Urban Design (1993) by Henry F.

Hur påverkas bentiska funktionella födogrupper av kalavverkning? : Effekt på abundans, samt återhämning, av funktionella födogrupper efter kalavverkning kring små vattendrag.

Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.

Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Kol-14 datering : En litteraturstudie över hur kol-14 isotopen används för datering, samt utveckling och tillämpning av djup-åldersmodeller inom naturgeografin.

This literature study concerned the use and function of the radioactive isotope carbon-14, as a dating method of organic material, within the scientific field of physical geography. In this report it is presented the need of atmospheric calibration curves and the development of these as a necessity to translate carbon-14 years to calibrated calendar years. A number of common age-depth models that is used to give an approximation of an accumulation sequence and its related dates over the actual time period in different natural archives is presented and discussed. Different problems that commonly occur when age-depth models are utilized as for instance reservoir effects, contaminations or other age deviations are addressed and analyzed. The software CLAM in presented and discussed and was also used to produce age-depth models.

Granföryngring på tallmark, hur ofta förekommer det? :

This survey was made during the summer of 2004 and the spring of 2005, on commission from the National Board of Forestry. The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.
