Miljögifter ? ett hot mot isbjörnens överlevnad?
De rådande klimatförändringarna drabbar Arktis och dess isbjörnar hårt. Smältande isar frigör miljögifter som i årtionden lagrats upp och kan nu ta sig in i och biomagnificeras i den marina näringskedjan, där isbjörnen som toppredator utsätts för hög toxisk stress. De försvinnande isarna utgör isbjörnens huvudsakliga jaktmark och detta skapar därför en ökad näringsmässig stress som
bryter ned kroppens fettreserver och frisätter lagrade toxiska kemikalier i blodomloppet.
Klimatförändringarna skapar ett gästvänligare Arktis, vilket tros innebära en förhöjd mänsklig närvaro som kan ökade halterna av lokala utsläpp och en rubbad näringskedja. Även introduktionen av nya djurarter tros öka vilket tillsammans med närvaron av människor i sin tur
kommer att orsaka en introduktion av nya patogener. Klimatförändringarna påverkar även havsoch luftströmmarna, vilket spås öka transporten av miljögifter till Arktis.

Rural development in Southeast Sweden- three different views and their consequences for the agrarian landscapeThis paper deals with the future for the rural areas of the southeast province of Östergötland, Sweden. The aim is to unveil, analyse and compare different views on rural development and their consequences for the agrarian landscape. Three views are considered, namely that of the different levels of Governments and their departments, that of the farmers and landowners and, finaly, that of the inhabitants of the rural areas.Differences in the views upon rural development is reflected in differences in the ways of thinking of landscapes. Is the open, and actively cultivated, landscape the ideal for all? Who is to decide what needs or ought to be done to achieve certain desired values and/or goals ? and who pays for it? The one thing that is, and should be, clear from the beginning is that all development, whether positive or negative in an area, bears consequences for the landscape.

Kristian Lundbergs gudomliga komedi : En intertextuell analys av Yarden, Mörkret skulle vara som ljuset och Och allt skall vara kärlek
This essay explores the intertextual qualities in and between Kristian Lundberg?s works Yarden, Mörkret skulle vara som ljuset and Och allt skall vara kärlek. Read as a trilogy, it bears a thematic resemblance to Dante Alighieri?s Divine Comedy; an autofictional depiction of emancipation from alienation by grace. To reach this conclusion, I use Julia Kristeva?s theory of intertextuality and Roland Barthes? post-structuralist differention of Work and Text together with his notion of the Paper-Author.
Name your price - a study of a pricing strategy
An industry in distress was the breeding ground for a noted pricing strategy, labeled name-your-price. The industry was the music industry and the pricing strategy bears reminiscence of how medieval buskers earned their living during the dark ages; by letting the customers decide how much the good was worth, embodied by a thrown coin into a hat or similar collector. Translated into the contemporary corporate environment of today, where technical innovations provides access to the intellectual property for free, a few mighty economic actors have once again turned to the strategy were it all started; letting the customer set the price. The hat has been replaced by a box for your credit card number and the live music by a MP3 file, but the similarity is striking. The business model have been applied in other industries as well with various levels of success, thus the purpose of this thesis is to set up a framework for where the name-your-price strategy is applicable.
Livskunskap : En inre kompass i skolan
Through qualitative interviews with five teachers from three schools, two public schools within the same school management and a Waldorf school, the purpose of this study is to find out teachers' views on the phenomenon of life skills in the lower classes in school. What is the subject, how do teachers work with life skills, and should it be seen as a separate subject or integrated in all school subjects?The results show that the definition of life skills is a term with many interpretations. Two concepts that can be seen as the common denominators in the educators' views on the subject, however is, social and emotional skills. This is something that educators believe develop self-awareness and empathy in children and sees that as important as learning other subjects.
Leanbana till toppen - En studie om Lean-implementering i skidsystem
The ski resort is a business unlike any other. While providing the customer with a service, it produces the service in a manner that in many respects resemble the traditional producing company. Therefore, since the challenges facing the ski resort are a mixture of what can be found in these different environments, this study aims to investigate the applicability of Lean principles in this context. With a qualitative approach based on direct observation, combined with survey data from 2819 respondents, we evaluate the expected effects on customer value of ten commonly defined Lean principles. The study finds that although Lean theory can help disseminate customers throughout the resort and provide greater transparency, the nature of the operations calls for caution.
Kromatografi av polära läkemedel och metaboliter med HILIC-teknik
The purpose of this project was to investigate if retention of polar compounds that are given to treat tuberculosis, diabetes, inflammatory bowel disease and childhood leukemia could be obtained with HILIC separation. By varying different parameters for different types of columns the compounds were analyzed with the aim of finding guidelines for future method optimizations. To perform these analyzes three different columns were tested ? ZIC-HILIC (silica-based with zwitterions), ZIC-pHILIC (polymer-based with zwitterions) and XBridge Amide (amide functions). The results were evaluated with selected quality measures.
Statskontoret, EU och statsförvaltningen En idéanalys av Statskontorets tankeföreställning rörande en europeiserad statsförvaltning
The purpose in this thesis is to explore the underlying conceptions concerningeuropeanization and public administration that Statskontoret is expressing in itspublications. Statskontoret is an agency in the service of the Swedish State whichprovides the Government and the Ministries with investigations and surveys. Themethodological choice in this thesis is to perform an idea analysis containing twoideal types which correspond with two polar theories, transnationalism andnation-state logic, concerning how a state will react on increasing european-ization. Initially, the theoretical framework is presented, and is followed by apresentation of the content in the relevant publications of Statskontoret. The idealtypes and the publications are examined from six different dimensions with theambition to explore the underlying conception in the publications.
Rekonstruktörens skadeståndsansvar
The thesis consists in two parts. The purpose of the first part is to analyse how the court may interpret rules, principles and legal cases to decide whether a reconstructor bears liability towards the debtor and the creditors. In the second part it is discussed and argued for how the reconstructor´s damage liability should be drawn up and applied so that it according to economic theories should be as efficient as possible. In the thesis it is shown that it is not a non-contractual liability or a liability based on authority mission. The reconstructor´s liability is instead based on a commission concerning an intellectual service.
SAB-systemet och ämnet religion en studie av ett klassifikationssystems förmåga att klassificera en vetenskaplig discipline.
Classification systems express an idea of the world as it was when the systems was made. If the classification system is not revised there is a possibility that the system will become antique and hard to apply to different subjects. The purpose of this study is to see if the SAB-system is a classification system which shows a reflection of the subject Religion that is equivalent with that of Swedish universities. The ideas which are behind the classification of the subject religion in the SAB-system have been analysed, as well as the structuring of the scientific discipline Religion at the universities. The result will show if the SAB-system can classify the subject religion in a satisfying way at university libraries.
Arbete befrämjar hälsa och välstånd... : en studie av arbetslöshetspolitiken i Uddevalla 1918-1932
This essay deals with Swedish unemployment politics during the period 1918-1932, and can be seen as a contribution to earlier research of how the policies, established by the State Unemployment Commission, was carried out at a local level. This study bears upon Uddevalla municipality, a town in the southwestern part of Sweden, which had about 13,700 inhabitants in 1920.The research was conducted in Uddevalla municipality archives, and the sources used are above all municipal records and documents from the local unemployment committee. The measures taken by the local committee to reduce the effects of unemployment have then been compared with the directives of the State Unemployment Commission.The survey shows that the local unemployment committee, at least during the first half of the 1920s, was very keen to follow the directives of the State Unemployment Commission, and they also tried to charge the municipality's economy as little as possible. The local policy was often even more restrictive than the demands from the State Unemployment Commission. During a few years in the middle of the 1920s, when the unemployment was relatively low, most of the unemployed did not recieve any help at all.The restrictive policy, however, led to an increasing distress among the unemployed, and the poor relief had to give financial help to a lot of unemployed and their families.
Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966
This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.
