Studie om individers kontrastkänslighet och preferenser för horisontell och vertikal belysningsstyrka
The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

Bärarskap av meticillinresistent Staphylococcus pseudintermedius (MRSP) hos svenska hundar :
During the last years, meticillin resistant Staphylococcus pseudintermedius (MRSP) have caused an increasing number of infections in Swedish dogs. MRSP is resistant against a majority of the antimicrobials available for dogs in Sweden, making it difficult to treat the infection. Our knowledge of the bacterium is limited, making it hard to handle infected dogs in a proper way. The aim of this study was to investigate for how long time dogs, who have an infection caused by MRSP, become carriers of the bacterium. Other factors like treatment with antimicrobials, the correlation between clinical symptoms and carriage, common diagnoses and institutionalization where also looked upon.
Åtgärder för biologisk mångfald i parker : Fallstudier i Botkyrka, Haninge och Nynäshamn
Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.
Sortimentsinriktad avverkning
Forest enterprises have always searched for ways to improve efficiency. For the past few
years there has been an emphasis on stock-keeping levels. Increased demand for fresh
round timber and the need to decrease the amount of tied-up capital has made the forest
industry reduce its inventory levels. This has brought on a higher demand on the timber
supply from the forest management districts concerning both delivery in time and
assortment output. As a result, the flow of timber has fluctuated a lot with serious
consequence for the timber supply during 1994.
Bekämpande av barnfattigdom : hur fyra aktörer i det civila samhället i Uppsala kommun uppfattar och hanterar barnfattigdom
ABSTRACT Poverty, and in particular child poverty, is a serious social problem. Statistics show that the number of children living in poverty has increased over the last ten years. Earlier research shows that there are huge gaps in our knowledge of how the actors in civil society handle child poverty. With this study we hope to help fill this gap. The aim of our study is to look at how four different organisations working in the civil society in Uppsala perceive and handle child poverty.
Samspelet mellan grafisk design och ljusdesign i utställningssalen "Vägen till det förflutna"
The purpose of this study was to develop recommendations for using more efficient lighting and better graphic design to create a more uniform structure in the exhibition hall ?Road to the past? in Jönköping County Museum by answering the following questions at issue:1) How are the objects in the exhibition hall ?Road to the past? exposed today?2) How can you use lighting and graphic design to create structure in the exhibition and strengthen the expression in the exhibition?Our work is based on observations and open group interviews. We observed the exhibition hall ?Road to the past? during day and evening. In the same hall, we observed a guided tour that we followed up with open group interviews.
Från 7-Eleven till vegetarisk KRAV-märkt buffé : Den förändrade organisationen av skolmåltider och dess relation till skolornas symboliska tillgångar
The purpose of this study is to examine how school meals are organized in a selection of Stockholm's secondary schools and to examine the relationship between school meals and the different parameters that indicate each school's symbolic capital and educational capital. By looking at the statistics from each school on the basis of the final grade average, percentage of pupils with foreign background and gender, I examine whether it is possible to see a relationship between how schools organize meals and which pupils attend the school. In my study, I systematically went through each school's website and tried to identify how school meals at each school are organized. To increase the validity of the study, I have also conducted a questionnaire survey by mail addressed to school principals. In order to analyse and understand my results and put them in relation to my current knowledge about the schools in my sample, I am using Bourdieu's theoretical tools that a given aid, both in methodological and analytical purpose. Based on Bourdieu's theories of symbolic capital, cultural capital and educational capital, I can understand and analyse school meals are organized and focused as part of schools' symbolic assets in competition with other schools. The first part of the study shows that there are four different organizational models for school meals, fully equipped kitchen and canteen, heating kitchen and canteen, school meals in restaurants and school meal card. In the second part, I have examined the relationship between the type of organization for school meals used and the symbolic resources available at the school. I can conclude from the results that it is difficult to find a correlation between the symbolic resources and the different categories. But even though it is not possible to see all the schools' symbolic assets equally clear, there are still some very telling examples. In many ways, these examples can be seen as polar opposites to each other based on Mikael Palme?s concepts ?goal rational? and ?education oriented? schools..

Lämpliga hybridaspkloner för odling i södra och mellersta Norrland
Hybridasp (Populus x wettsteinii) är en snabbväxande hybrid mellan europeisk asp (Populus tremula L.) och nordamerikansk asp (Populus tremuloides Mich.). Det finns svenskt hybridaspmaterial framtaget för odling i Götaland men inte för övriga delar av Sverige. För odling av hybridasp i övriga delar av Sverige rekommenderas ofta finländskt odlingsmaterial. Hybridasp lämpar sig väl som biobränsle tack vare dess höga tillväxt och då efterfrågan på biobränslen förväntas öka är det viktigt att ta fram ett hybridaspmaterial som har högre härdighet och tillväxt än de hybridaspkloner som finns på marknaden idag. Målet med denna studie var att göra ett urval av lämpliga hybridaspkloner för odling i södra och mellersta Norrland utifrån försök med nyframtagna korsningar.

"Nu är det riktigt, riktigt, riktigt, riktigt besvärligt" : En kvalitativ analys av TT:s rapportering om barn och unga som flyr ensamma till Sverige.
Today many separated children and youth up to 18 years - children in the sense of the UN Convention on the Rights of the Child - flee from war and armed conflicts around the world. Many of them come to Sweden for protection and to apply for asylum.The aim of this study is to examine how the national Swedish news agency Tidningarnas Telegrambyrå - TT - constructs the image of separated children and youth. The main research questions have been: How does TT construct the image of the separated refugee children? The more detailed questions put to examine this main question have been: what are the issues being focused in the reporting and what discourses, voices and sources are let into the journalistic material?The theoretical perspective should be considered as social constructionistic where the basic idea is that the image of the separated child also constructs the way society looks upon them, their rights and their needs, affecting how these children will be welcomed and treated when thay arrive in our society. The empirical study is a qualitative analysis of text, produced in the span 2007- April 20th 2010.
Mobbning inom föreningsidrotten
Denna studie omfattar mobbning inom föreningsidrotten, vi har valt att undersöka om Malmös idrottsföreningar har någon nedskriven antimobbningspolicy och/eller ? handlingsplan och därutöver har vi intervjuat tio föreningar om hur de konkret arbetar med mobbningsfrågor. Vi har också valt att titta på samverkan mellan skolan och idrottsförening vid mobbnings incidenter. Studien bygger på kvalitativ forskningsmetodik, totalt 14 intervjuer. Anledningen till varför studien grundar sig i kvalitativ metod är för att vi vill se orsaken bakom fenomenet, ej generalisera svaren samt att den är mindre resurskrävande.
