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.

When performing studies that test the reactions of horses in different situations, important information may be available about the horse?s reactivity level. With information from these tests, accidents and dangerous situations may be prevented. When the behaviours from tests are compared with race performance it may be possible to evaluate if some behaviours are more desirable at the race track than others. The aim of this study was to see if behavioural responses correlated with physiological parameters (heart rate, cortisol), the trainer?s opinions and actual race performance.

The horses have been in the care of humans for about 5000-7000 years. But even though the horses have been domesticated and artificial selected for such a long time their natural behaviours and instincts still remains. In the rich countries there are many people who have the opportunity to ride either on their own horses or at riding schools. Many of these people have not grown up on farms and have no experience of handling big animals. This can lead to implications of the horses? welfare.

This thesis examines the deregulation reform of the Swedish railroad industry, focusing on passenger transport between 1988 and 2005. The purpose of the thesis is to examine the effects from the deregulation reform on prices, market concentration and to determine whether SJ (the state owned incumbent) has been conducting strategic behaviour in order to prevent new entrants to the market. The chosen method consists of interviews with the MD at SJ between 1988 - 1998 Mr Karl-Erik Strand, the transportation researcher at SSE Mr Gunnar Alexandersson. Statistical sources and companies financial reports have also been used. The results that I have found were besides the fact that the market concentration is still significant high and the profitability among the operators low, is that the prices has increased more than CPI during the period but the competitive tendering has resulted in lower government subsidies after the deregulation.

This thesis examines political consumerism as a political tool for change. Consumers' attitudes and behaviour towards political consumerism is of special interest. The method used is a questionnaire with 59 participating students. Their answers are analysed both quantitatively and, to a lesser degree, qualitatively. The theoretical framework consists of Fishbein and Ajzen's theory of reasoned action and previously published research of essence.The consumers in this study generally rank corporate social responsibility (CSR) as important.

The music distribution in Sweden and the world is rapidly changing. The music industry, however, has been reluctant to change the way they distribute music. The consequence has been that illegal music files have been available for downloading to anyone with an Internet connection. Because of the illegal downloading a new law have been implemented in an attempt to stop this behaviour. Our theory is that in implementing the IPRED-law, the sites that were hosting most of the illegal material will experience a severe decrease in traffic.

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

The main purpose for this study was to examine how boys with destructive and self-harming behaviour are perceived and comprehended by school counsellors and literature. The study assessed how boys who harm themselves are defined both in practice and in theory by using a social constructivist point of view and a gender perspective. The study was divided in two parts concerning gathering knowledge of the matter. The authors, using a method called qualitative semi-structured interviews, interviewed nine school counsellors. To acquire scientific knowledge, the authors implemented a literature review and researched books and journal articles regarding boys who self-harm.

Modern milk production have come a long way when it comes to accommodating the nutritional and physiological needs of the animals, but unfortunately the behavioural and psychological needs of cows and heifers are often left unfulfilled. A long time for eating is beneficial for the digestion and also gives the cattle something to do and decreases the risks for developing abnormal behaviours. An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours. The study was conducted at Uddetorp farm high school in Skara. Forty-two heifers of the breeds SR and SF were housed in 8 slatted floor pens.

Syftet med studien var att undersöka ungdomars uttryckta attityder gentemot alkoholrelaterade handlingar samt att ta reda på hur de upplever den subjektiva normen från föräldrarna. Frågeställningarna var: Vilken attityd uttrycker ungdomen gentemot alkoholrelaterade handlingar? Hur uppfattar ungdomen den subjektiva normen från föräldrar och vänner när det gäller alkoholrelaterade handlingar? Finns det något samband mellan ungdomens uttryckta attityd gentemot alkoholrelaterade handlingar och upplevelsen av föräldrarnas attityd gentemot alkoholrelaterade handlingar? Hur skiljer sig de uttryckta attityderna åt mellan ungdomarna beroende på kulturell bakgrund och kön? Den kvantitativa utgångspunkten valdes för studien och Theory of Planned Behaviour användes som teoretisk utgångspunkt. Resultatet visade att respondenterna uttrycker främst negativa attityder gentemot alkoholrelaterade handlingar. Respondenterna upplever en negativ subjektiv norm från föräldrarna.

Health and convenience trends dominate the food industry and retailing business of today. The health consciousness is spreading while appealing product attributes concerning taste and packaging also are increasingly important. At the same time, the competition is growing fierce in the Swedish market with hard discount formats and niche concepts who also are trying to provide the market with perishables. Therefore, the pressure to lower prices is increasing making economies of scale and rationalization progressively more important. In 2004, ICA launched private label meat packaged in a modified atmosphere. Consequently, many stores went from in-store cutting-up and packaging to selling centrally packaged and distributed meat. ICA is now developing a concept with fresh fish in modified atmosphere packages and needs to increase the knowledge about the market and the consumer.

In this paper the authors examine three questions: 1) Is stealth marketing messages posing as status updates on Facebook a more effective way of advertising than traditional web banners? 2) What impact has learning about stealth marketing practices in social media on consumer attitude and post purchase behaviour? And finally 3) Will different generations respond differently to these questions?Our findings show that stealth marketing in social media is not more effective than traditional web banners. Furthermore, the result indicates that when consumers find out about stealth marketing practices it will have a negative impact on future purchase intensions and brand image. Most consumers will also have strong feelings of being deceived, which could instigate harmful post purchase behaviour such as negative word-of-mouth and possibly, based on some earlier cases, boycotts.The result of our research shows that the brand perceptions and future purchase intentions of Generation Y, persons between 18 and 30 years of age, are affected in a less negative way than the brand perceptions and future purchase intentions of older generations when finding out about stealth marketing practices in social media. However Generation Y:s reaction is still negative and they do consider traditional web banners to be more credible than status updates on Facebook.

During the last decade millions of people have migrated to Europe. Parallel to this development, we see that many countries are becoming more hostile towards immigration. The success of radical right-wing parties (RHP) has been accredited to natives within the receiving countries turning to RHP to reduce their perceived threat from immigrants. Paradoxically, the RHP-support has also increased significantly among the immigrant population given the common assumption that immigrants are in solidarity with regards to shared experiences of immigration. In this dissertation, I argue for the importance of considering the increased RHP-support amongst immigrants, something that has been neglected in contemporary research.

The purpose of this study was to explore the connection between substance abuse and completed/attempted suicide. Central questions were who the substance abusers who commit suicidal actions were. The study also tries to find out which factors that contributes to this behaviour and why it is so common amongst substance abusers. All from the point of view of three scientist and three persons working with treatment of addicts who were interviewed. The results of these interviews were analysed on an individual level with a psychological theory.
