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.

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

The school is under constant change and school reform on the conveyor belt. In 2009 the Swedish government introduced new directives for the elementaryschool, including multi-national sample, written testimonials from grade one and grade with several grades rose from grade six. The purpose of this study is to examine currently active primary teacher perceptions of the pupils' learning and development might be affected by those earlier and clearer knowledge assessments, and how teachers perceive this reform on the basis of the Swedish school's motto "a school for all". The study was carried out with a phenomenological approach where the method has been depth interviews with five active primary teachers from grades one to six in a school. The results show that teachers perceive that the earlier and clearer assessments will affect students differently according to student performance and knowledge.

This report is based upon an experimental study of exit sign luminescence in different environments. The purpose is to evaluate the lowest luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in two department stores. The final result of the study is guidelines for appropriate exit sign luminescence in different environments..

This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower. A generation of ideas followed with an evaluation to select the best solution. The winning concept was further developed to reach acceptable performance. The word resulted in a functioning prototype utilising an original way of detecting inclinations without incorrect signals. It c an serve as a platform for further development into a product.The work gives insightful experience of solving real-world problems, and especially to deal with situations where several variables and their effects are unknownPlease note that several parts of the work are confidential, and have therefore been removed from the thesis..

This master thesis is based on a general issue of quality in social services. I have chosen to illustrate through an empirical case, namely the position social responsibility coordinator and shortened SAS.This position is fairly new to the Swedish social services and has the overall mandate to monitor, develop and ensure quality.To study this, I have developed two analytic schemes. One is based on the concept of quality value components, the second is based on the concept of quality character components. These analytical schemes are used as the presented material. When I study mycase, I have used two methods, documents and questionnaires.In this study I will try to describe how new solutions to improve the quality of social services can conform and develop.

The purpose of this paper is to explore the social worker?s perspective on working for the government as a professional in care of children, in relation to the family's right to self determination. The essay's empirical material is gathered from qualitative, semi-structured interviews with social workers who work with children and youth in communities and districts in Skåne and Stockholm City, Sweden. The analysis was conducted in line with theories of social constructivism. The results and analysis show that the interviewed social workers did not believe that the state has too much power over the citizen.

The purpose of this essay is to study the process of developing electronic subject guides for the Internet. Our focus is the content, structure and layout of the subject guide. The study has resulted in a number of guidelines that may be of help in the development of future subject guides. To achieve this purpose we have studied the existing subject guide at one of the faculties of the University of Lund, Sweden. We performed a series of interviews with the originators, and made a questionnaire for the users.

The current debate regarding organizational strategies for sustainabledevelopment is influenced by the theory of global governance. Decentralizedstructures of the global society are taken to use in the realization of a sustainabledevelopment. New roles of transnational networks and partnerships raisesquestions of the ability of global governance to co-ordinate and implement longtermsolutions without assistance from centralized and hierarchic structures basedon government. The aim for this thesis is to illustrate the current conditions forwell-functioning networks of sustainable development and examine therelationship between global governance and government. Issues of participation,decision making and compliance are examined by a case study of the Marrakechprocess, a global process to support the implementation of sustainableconsumption and production.

During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future. I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection. Included in the study are four areas, three of which burned in 2005 and one in 2006.

Title: ?When The Line Between Transmitter and Receiver Blurs? ? A Study of how organizations look at social media as part of their external communication and how they respond to the environment in the new media toolNumber of pages: 49 (51 including enclosures)Author: Ida Hansson KällTutor: Cecilia StrandCourse: Media and Communication Studies D 30hpPeriod: Spring 2010University: Division of Media and Communication, Department of Informatics and Media,Uppsala UniversityPurpose/Aim: The aim of this essay is to study how five organizations look at social media as part of their external communication and how they respond to the environment in the new media tool.Material/Method: A qualitative method has been used. Five interviews as primary sources have been conducted with representatives from each organization.Main results: The main results of the study is that organizations have to integrate social media as part of their external communication plans in order to face and respond to their surroundings in a new interaction and multi-way communicative platform.

The purpose of this study is to investigate the effect of physical activity for people suffering from depression and which nursing interventions nurses can do to make this patients start to exercise. The method used, is a review of articles from Ci-nahl, Cochrane, Elin, PsycInfo, Pubmed and Science Direct, which were analyzed according to Polit och Hunglers criteria for scientific research. The result from the nine studies shows that physical activity has an antidepressive and anxiety reduc-ing effect. Interventions emerged is supporting, encouraging, activating and teach-ing about physical activity as health-promoting measure. Conclusion: Nurses can as an intervention introduce exercise as complementary treatment for people suffering from depression.

År 1987 trädde en ny byggnadslag i kraft, Plan- och bygglagen(PBL). I och med den nya lagen minskade kommunens och byggnadsnämndens kontroll av projekteringshandlingar och besiktningar ute på arbetsplatsen. Efter lagändringen beror den slutgiltiga kvaliteten på en byggnad i större utsträckning på byggherrens och entreprenörernas egenkontroll. P.g.a. olika intressekonflikter inom kommunen, och att det kan förekomma starka kopplingar mellan byggherre och entreprenör, är det inte alltid självklart att kommunens tillsyn vid nybyggnation gällande till exempel egenskapskrav på energihushållning och värmeisolering utförs tillfredsställande.Med ovanstående i åtanke undersökte vi fyra flerbostadshus, två i Värnamo kommun samt två i Kristianstad.

The aim with this thesis is to investigate two different methods used to test usability on web-sites to determine the advantages and disadvantages of two methods and compare the results. The two selected methods are the think aloud method and asynchronous remote method. Re-mote usability testing has existed for more than ten years but the possibilities with this meth-od needs to be explored more.To achieve the purpose of this thesis a case study was conducted on an e-commerce site and for the online remote usability testing software was used.The results of this study show that think aloud usability testing encounter more issues with the website than the remote usability testing..

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
