Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the biomass, leaf area index (LAI) and growth stage of the plant on the interception and retention is important to know in order to decide which countermeasures to use. Weather may also be an important factor. In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.

What attribute affects salience on a political agenda? How come some reforms are implemented while others are not? These are essential and central questions for our society. Our society, our democracy and our everyday life are dependent of these factors; communication is the condition. In the 2011 budget from the Swedish conservative government, the question of lowering the VAT on restaurant- and catering services was the single most debated reform. This was occasioned from 2009 when the European Union allowed, for the first time since Swedish entry in 2005, a lower VAT on restaurant services.

In the past years the traditional donors of development assistance have been increasingly aware of changes in the donor landscape. This as emerging economies like China and India has undergone a transition from recieving aid to becoming emerging donors. By identifying and comparing ideas, beliefs and interests pursued using foreign aid between so called emerging and traditional donors, the greater purpose of this thesis is to take a closer look at the alleged changes in the world order. The starting point is Goldstein & Keohanes framework of the impact of ideas and interests in foreign policy and the one of K.J Holsti about institutions as markers metrics of change. The results show that there is no vast difference in interests but a detectable difference in the ideas behind foreign aid.

Introduction: Parents have been shown to be of great importance in preventing cannabis use among adolescents. Parenting practices such as control, open communication and good relations within the family have shown to be protective factors, whereas lack of communication and weak social and emotional support have been associated with an increased risk for cannabis use among adolescents. Aim: The aim of the study has been to explore parents? perceptions about their own importance in preventing cannabis use among adolescents. Method: A qualitative method consisting of focus group interviews has been used to fulfill the aim.

To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial factor. It is also important to know which key parameters that should be tracked. In this work well established routines for heat detection have to be applied. When the dairy farmers use technical aid in estrus control it is important not to forget that technical aids can not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed because clear signs of estrus have not been displayed and/or recorded. The cattle fertility has been declining over recent years. During the same time the cow?s proceeds have increased, consequently applying a higher pressure on the cow and the manager.

The purpose of the study is to contribute knowledge about the representation of fiction authors who have written in languages other than Swedish in educational school books within the Swedish subject. This is done in relation to the school's promotion of cultural diversity, a globalized world and to the Swedish curriculum. The study is a combination of a qualitative and a quantitative analysis that takes its starting point in six educational books for the courses Swedish 1 and 2. The analysis shows that all study materials include a broad representation of authorships from Europe and the USA. The selection of authors from other parts of the world is, however, limited.

The public sector has through the years been exposed to a rather radical alteration. The aim with this alteration has been to make the public sector more effective. It?s a dynamic society that Norrbottens läns landsting (NLL) operates in today and it is therefore of great importance that the managers get a solid foundation to rely on, since they have a central role in the ambition for efficiency. Another reason to educating the managers is that NLL can secure the future pension losses.

This essay has a purpose to understand and investigate how disabled people, where the handicap imply difficulty to speak for one self, get the rights of self-determination and influence satisfied. Our purpose with this essay is to focus on how representatives from organizations, trustees and Support and Service for Persons with Certain functional Impairments- officials(abbreviated LSS after the Swedish title of the Act lag om stöd och service till vissa funktionshindrade), describe and discuss matters concerning the individuals? opinions and requests from within their respective position. We will with this as a base analyze how these three parties facilitate and meet the individuals? influence and self-determination.

About 29 000 different services was given by the Swedish welfare state to children with disabilities within the ages 0-22 years before October first in the year 2008. Studies about children with disabilities and their experiences of their situation have rarely been done and it is therefore difficult to know how they think and feel about their lives. Both Swedish law and the UN:s convention about children?s rights states that children have the right to tell their opinion in matters that are of their concern. Thus, we don´t know much about if and how the Swedish welfare state maintain this right towards children with disabilities.

This thesis aims towards an understanding of information systems and subject representation in relation to academic disciplines. This is achieved by comparing how a discipline, History of science and ideas, represents itself compared with the subject representation of its dissertations in an information system, LIBRIS. The point of departure for this thesis is the domain analytic view of Hjorland which states that the quality in information seeking is enhanced if the subject representation considers the contexts in which documents are produced and used. The importance of concepts such as domain and discipline is discussed. The disciplines view of itself is established by the study of articles written by scholars in the discipline, by how the discipline presents itself on the homepages of five university institutions and by the examination of titles and keywords given to dissertations in the discipline.

A buyer of a new car is often offered a various selection of warranties. A warranty can e.g. exist in the form of an extended new car warranty. However, some manufacturers demand that the car has to be serviced by an authorised repairer for the validity of an extended warranty. In the thesis I analyse whether such a contractual term is incompatible with today?s legislation and I argue for when such a term is to be seen as unfair.

This study has examined if importation of waste for energy recovery can reduce the climate impacts of Waste Management Systems. Using Systems Analysis this study will try to examine the complex waste systems in a systematical and strictly logical way to see how these systems interact and affect each other. Specifically examining the climate impact of waste management systems in England. The traditional way of handling waste in England is through Landfills. Land filling leads to emissions of the greenhouse gas Methane. The EU has put in place a landfill directive that is supposed to lead the member states away from land filling as a method of waste management. Today in Sweden there is a competition for the waste available for incineration. The worsening economical situation together with less product packaging and an increase in source separation leads to a lack of waste available for incineration.
