Pigs kept for meatproduction are often surgically castrated to prevent aggression and boartainted meat. Castration without analgesia and anesthesia is painful and causes a lot of stress to the pig. There are alternatives such as to surgically castrate the male pigs with analgesia and/or with anesthesia, immunocastrate or keep them as intact males. In Sweden the most common practice is to surgically castrate the pigs before they are seven days old. The impact on the pig is that the incision causes pain and stress, which may lead to changes in behaviour, reduced appetite, reduced growth and a higher risk of infections.

Self-destructive behaviour is a more and more occurring phenomenon in today?s society and there are mostly young girls who are affected by this behaviour. There are different explanations to why the phenomenon appears. The purpose of this research essay is to give a literature overview of the phenomenon of self-harming behaviour of young girls. Two research questions have been used to study this phenomenon; How can groups of friends contribute to reinforce an identity with the self-destructive behaviour among young girls? How can Internet contributes to reinforce an identity with the self- estructive behaviour among young girls? For the analysis this research essay uses the social constructive theoretical perspective.

Dog bites pose a threat to public health globally and can lead to infection, disfigurement, incapacity, post-traumatic stress syndrome and even death. In geographical areas where rabies is endemic, bites from infected dogs account for over 90% of the human rabies cases. Children have been proven to be at a greater risk of being bitten by dogs and subsequently contracting rabies than adults. In this cross-sectional study, a school survey was undertaken in association with a rabies awareness campaign in India, to investigate the dog bite incidence and various risk factors associated with dog bites as well as assessing the knowledge of safe interaction with dogs among children in the age group 10-18 years. A total of 1295 questionnaires were collected. 43.2 % (n=556) out of the respondents were boys and 56.8 % (n=731) were girls with a mean age of 14 years.

During the last decades major changes has occurred at the financial markets, meaning an increasing supply and a greater variation of financial instruments. The saving habits of the Swedish people have gone from traditional bank deposits to investments in equities, funds and bonds. All this together with the great rise in the stock market at the late 90?s has brought words like risk and return up-to-date, and is the background to the development of a new law concerning financial advising which come into force the 1th of July 2004. The contents of the thesis can be described as three bricks, representing the survey questions.

Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.

Background: From a public health perspective it is of great interest to prevent the risk of noise induced hearing loss, because in addition to hearing loss, tinnitus and sound sensitivity also may lead to other health problems. About 1,4 million people in Sweden live with some form of hearing loss and 25000 of them are children under the age of 16. Studies have shown that hearing loss among adolescents is increasing and it is often associated with sound environments in their leisure time. Lectures in hearing prevention has been conducted in schools for adolescents but have not reached the desired results. Objective: To enquire caregivers? attitude, behaviour and perceived knowledge about sound exposure and its risks.

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.

Sexual violence in armed conflict is not a new phenomenon. Although it has a long history, it's only in recent years from 1990 that is has been given more attention in science and media. I will in my thesis look at the conflicts of former Yugoslavia and Congo (DRC) and I will use two theories to investigate how the use of conflict-related sexual violence best can be explained. The two theoretical frameworks I have chosen are Feminist theory and Rational Choice theory. The conflicts will be at the center of analysis.

We have from three studies examined how adolescents and young adults, actors and the researchfield describes the preventive and health promotion work with sexual health. The questions weasked ourselves was based on what efforts adolescents and young adults demand, whether there aredifferences between age, gender, place of residence, ethnicity, employment, and sexual orientation.Furthermore, we investigate if these requirements are consistent with the offered interventions fromparticipants, as well as which perspectives the work with STI / HIV and SRHR issues should bebased on. The investigation concerns the work of Västra Götaland and is answered by interviewswith participants regarding the activities offered by actors, a quantitative analysis and text analysisof the answers of adolescents and young adults, and an international research overview of theresearch field. Our results show a high demand for basic preventive work from the adolescents andyoung adults. Furthermore, there is an increased demand of action from men, LGBTQ group anddepending on the place of residence.

By tradition horses are weaned at an age of 5-6 months. This study illuminates weaned foals misdirected suckling behaviour, which means that they try to suckle another foal. Since no information about this issue is presented, we decided to perform a behaviour study on weaned foals. The misdirected suckling behaviour was studied on a group with 7 foals, with both fillies and colts. In the group the weaning age varied between 147 days and 215 days, and the first time we observed them, they had been separated from the mares for 12 days.

The primary aim of the current study was to gain increased knowledge about drivers' risk experiences. The study was based on questionnaires answered by 30 private drivers and 30 bus drivers, with 50% men and 50% woman in each group. The study revealed no differences, either between men and women drivers with regard to their experience of risk, or between the groups of private and bus drivers. Gambling is common within the private drivers group. Mistakes are common in all groups.

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.

Introduction: The National Board of Health and Welfares conclusion was that today there was a low awareness about children who act sexually toward others and how their problems can be handled. This requires extensive work by school personnel and social workers to give the children the support they need. Aim: The aim was to investigate social workers perception in cases concerning children and adolescents who committed sexual assault. Method: A qualitative method was utilized with semi-structured interviews to describe social workers perceptions in cases concerning children and adolescents who committed sexual assault. Four social workers from different communities were interviewed in southern Sweden.

Information regarding cows grazing behaviour and time spent grazing can be of great interest to dairy farmers, since this information can indicate how well suited the pasture is to the cows. Feed intake at pasture is however challenging to measure. Automated systems for monitoring the behaviour of cows within dairy production have become increasingly important and relatively common. The aim of this study was to validate an activity measuring device (HOBO® G Logger Pendant Data Logger, USA), a triaxial accelerometer that registers the cow?s head positions during grazing, in order to see if cows? grazing behaviour on pasture could be distinguished from their non grazing behaviour.

It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.
