EN ANNAN RETORIK? Nationalistiska partiers anv?ndning av nationalistisk milj?- och klimatpolitik
Climate change is a phenomenon that know no boundaries. While focus on environment and
climate change has become highly prioritized, nationalism has spread across Europe.
Nationalism is by many considered to refuse action to combat climate change although some
argue that nationalism could combat global climate change. Previous research on how
nationalism is implemented in environment and climate politics has mainly focused on single
parties. The thesis therefore aims to give a broad approach and compare how nationalism is
used in environment and climate politics by analyzing 4 European parties with either ethnic or
civic nationalism and different roles in their party system. With a qualitative content analysis
on party programs and election manifestos the findings imply that parties use nationalism in
the climate and environment discourse in a variety of ways.

En studie om vad som behövs för att skolträdgårdar skall fungera under en längre tid : en utvärdering av Edane skolas skolträdgård
Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.
"Målet är att dom ska fixa så mycket som möjligt själva" : En kvalitativ studie om förskolans inomhusmiljö som ett pedagogiskt redskap för barns självständighet.
Abstract Study: Degree project in teacher education, Advanced level, 15 hpUniversity of Skövde.Title: ?The aim is for them to manage as much as possible on their own? ? a qualitative study of preschools´ indoor environment as a pedagogical tool for the independence of children.Number of pages: 31Author: Jenny Karlsson, Marie PerssonTuto: Gunvi BrobegDate: 2009-01-28 Keywords: Independence, indoor environment, preschool, pedagouge This study aims at examining the indoor environment of three different preschools as a pedagogical tool for the independence of children. Is the design of the premises adapted to the height of the children? Can they themselves reach the material they need and is it possible for them to reach their outdoor clothes or do they constantly have to ask for help? In order to acquire a deeper understanding of the different views of the three preschools, the question is asked: what are the pedagogues thoughts of the indoor environment of their own preschool in the perspective of childrens independence and what affects their choice of furnishing, planning etc? The preschool curriculum clearly states that the children must be given the opportunity to develop their independence. We have experianced that the pedagogues feel that they are unable to plan the environment as they wish and thus, interest is also pointed towards the question: are there any limiting factors that affect the design of the indoor environment, and, that being the case, which are they? The study is based on qualitative observations and interviews because it is in its interest to discern patterns and categories rather than quantity.
Klotter och skadegörelse på en högstadieskola: en miljöpsykologisk fallstudie med fokus på fysisk miljö.
The purpose of this study was to examine and try to understand the physical environment focusing on the fenomena of scribble and damage at a high school. More specifically its aim was to find out how the pupils themselves discribe their physical environment, the reasons why there are scribble and damage at their school and how they are treated by the adults at the school bearing in mind the scribble and damage that occur. The study took place at one high-school in the southern of Sweden and the methods used were six qualitative interviewes, a minor inquiry in six classes, fotographing the physical environment and putting up scribble boards on the pupils' toilets. The physcial environment was quite bare and monoton and the pupils often felt bored by it. There were few places where the pupils liked being at.
Valet och kvalet kring kapitalstrukturen : om kognitionens inverkan på finansieringspolitiken
Background: A company?s choice of capital structure is influenced by the access to internal and external capital but also by the opportunities and threats that the management perceives in the environment and the management?s attitude towards risk. How an individual perceives and interpret the environment depends on the cognitive structures, which are shaped by personality, background and earlier experiences. Accordingly cognitive structures can be expected to influence the choice of capital structure. Purpose: Out of a cognitive perspective we intend to study the relationship between the way a company views it?s environment and what capital structure it chooses to have, in order to contribute to an increased understanding about what lies behind a company?s capital structure policy.

Rengöring, desinfektion och förvaring avendoskop i djursjukvården
With a starting point in the legislation for organic production set up by the Swedishcertification organization KRAV, the reasons to why these regulations are important isexplained and how pigs are affected by these rules. The study also shows how well the pigscope in the organic environment considering the origin of the genetic material; from theconventional pig population. The conclusion is that pigs do function fairly well in the organicproduction environment and the traits affecting their functionality involve: motheringabilities, strong legs, good meat quality, good sow durability and longevity, capacity to eatmuch roughage and dark skin color. There are however still many ways of improving theorganic population of pigs to make them more adjusted to the organic environment; forexample different traits brought into the breeding goals and the choice of good parent animals..
Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät
In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Växtanvändning i krävande miljöer : en studie i sydvästra skåne
Vegetation is a much appreciated element in our outdoor environment that has many advantages as well for the climate as for people?s health. However in some types of environments vegetation may be problematic. Especially in urban areas with limited space, solid surfaces, pollutions, and warm and dry climate. In these environments vegetations may have difficulty surviving and moreover it may have a negative impact on the environment around it.
Vision Enhancement System : Vilken betydelse har displayplaceringen?
At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.
