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.

The purpose of this study is to show what melancholy and irony in my poems express and what techniques that are used to accomplish these effects. Many theorists, among them Sigmund Freud and Julia Kristeva, characterize melancholy as an experience of loss, and therefore one of my questions is what kind of losses appear in my poetry. In search for an answer I analyze the texts from both a psychoanalytic and a sociological point of view. In the latter perspective I discuss the postmodern society using concepts from contemporary thinkers like Zygmunt Bauman, Fredric Jameson and Jean Baudrillard. Finally, I also examine if melancholy has an influence on the form of the poems.

On October 17, 2012, TV4 broadcasted an episode of the documentary series Kalla fakta. The episode received a lot of attention when it revealed that Parken Zoo, a very popular destination for families, was not as well maintained beneath the surface as it gave the impression of being. The case attracted attention in all possible media for a long time, which led to a beginning of an extensive investigation of the Zoo.The purpose of this study is to examine how Parken Zoo handled the media after the examination of TV4?s Kalla fakta, and how it affected people?s confidence in the Zoo. This paper consists of an overall case study of Parken Zoo that can be divided into two different methods.

Healthcare staff working within emergency care must often handle extreme and emotional situations. Most of the certified registered nurse anesthetists (CRNAs) will some time during their professionally active lives confront with events that are difficult to handle and for some these events will lead to more or less serious traumatic distress and in certain cases develop post traumatic stress disorder symptoms. Many studies demonstrate that staff working in similar stress related environment runs larger risk in order to get stress related symptoms. The aim with the study was to describe the experiences around difficult work related events among CRNAs. The study was implemented as a descriptive study with qualitative run-up via a questionnaire with open questions relevant for the study's aim.

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.

The use of laptops, interactive whiteboards and the Internet is step-by-step working it?s way into Swedish schools. The aim of this study is to investigate the attitudes of teachers towards using IT-related tools in their teaching. How are the tools given used as mediating tools, what new methods do the teachers find themselves discovering while using these, how do the teachers feel about digital teaching platforms and how do the IT-related tools affect students language progression? These are all questions that this study is meant to answer.

The aim of this thesis is to analyze the media discussions of the rape in Bjästa 2009 and to reveal how stereotypical illusions of ethnicity, religion and gender affect how media understands and defines violence. The rape in Bjästa occurred in a ?Swedish context? but has been defined as honor related in other arenas outside media. This discussion occurred because the whole village turned against the woman that was raped and supported the perpetrator? a phenomena that speaks against the idea of an equal society and a behavior that is usually understood as honor related and something that the ?others? do.

The purpose of this study was to conduct a qualitative study with a case study research design, where we studied social workers and politicians view on honor-related problems of underage girls and boys in the age 13-17. We need knowledge about honor related violence and oppression in the political community and social services to work with honor-related problems. Political decisions affect how social work is developed around the honor problem; therefore, it is also important to highlight this direction for the work. It requires a knowledge complement of honor-related problems not to risk exposing the child to further risk from the family (Hedersförtryck, 2009). This is to live up to, for example the law of Social Services, school law and Human Rights (Hussein & Kinuka-Svedberg, 2010).

The aim of this qualitative study was to examine bereaved individuals? experiences of support from their social networks and participation in support groups. The theoretical framework is based on theories about social support and parts of the attachment theory. Data were collected from four interviews and analysed by the study?s theoretical framework.

The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject.

People spend much of their timeat work and health is affected by how we experience our everyday work situation. Health in the workplace is important for public health and seems to improve the occupational health of theemployees. The pace of work and requirements have hasincreased at work and it's not equal accepted to have an obstacle that makesyour work capacity decreases. Despite this, there are health factors that enable us meet therequirements and can maintaingood health in the workplace. Theaim of the studywas to see if there has beena change in healthcare workers work-related health over time.

This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.

The aim of this study was to investigate whether a dietary change, physical activity or a combination of both gave the best result when treating obesity, concerning weight loss and BMI. Excessive weight and obesity are today a big health-issue and it is estimated that 10 % of the men and 12 % of the women in Sweden have a BMI over 30, i.e. are suffering from obesity. The corresponding number for children is 3 %. No one can say for sure what causes obesity but there are many theories.
