The questions we wanted to examine were how they worked with these children, how they motivated their work and which theoretical perspectives they used. The method that was used was a qualitative interview, where six social workers were interviewed. The result showed that their work foremost was based on conversation methods and all social workers emphasized the importance of a near cooperation with the parents since they considered that parents had the strongest influence on the children. Some social workers focused foremost on altering children's Aggressive behavior while others focused on understanding the meaning of the behavior.

In 2012, about 1.3 million boars were surgically castrated, most of them without anaesthesia. Castration is performed to avoid the occurrence of boar taint and aggressive and sexual behaviour. There is a growing concern about the welfare of the piglets and the Swedish Board of Agriculture is working to find efficient and functional alternatives to castration without anaesthesia. The aim of this study was to obtain an overall picture of the latest research about the alternatives to castration without anaesthesia, with focus on vaccination against boar taint, and how they affect the welfare of the pigs. The alternative methods that are available today are surgical castration with anaesthesia and/or analgesia, rearing entire males and vaccination against boar taint.

The aim of this study is to examine the information behavior of younger seniors with a special focus on the Internet. Using a qualitative method consisting of a case study, including observations, diaries, questionnaires, and information diaries, we were able to compare the information behavior of the seniors in their use of the Internet, with the information behavior in their everyday life. The result of the study shows that the respondents led very active lives and used many different information sources in everyday life. They did not only seek information, but also assimilated it, often with a purpose to mediate it to other people. The motives behind the information use in everyday life were mainly connected to their life situations.

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.

Att arbeta med ART metoden är en kvalitativ studie med syftet att ta reda på hur ett specifikt arbetslag arbetar med modellen Aggressive Replacement Training (ART) i en skolverksamhet. ART metoden är en beteendeförändringsmodell skapad för kriminella utåtagerande och aggressiva unga. Utveckling av ART metoden och dess anpassningsbarhet har gjort den till en arbetsmodell som används inom skolan, då modellen anses kunna ge alla barn och unga verktyg och träning i dess sociala och emotionella utveckling.
