The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

Stress is common in today?s society, but the word stress has numerous connotations. The aim of this study was to investigate how dogs are effected by stress and what the veterinary nurse can do to help dogs to avoid or at least mitigate stress within the veterinary hospital. The goal was also to see how dogs perceive the environment in the veterinary hospital and what behaviours dogs demonstrate when they enter the hospital and during their stay. Studies have shown that dogs have a reluctant feeling on entering a veterinary hospital. They can feel stressed by coming to a new environment, as well as by being put in a cage with no control over what is going to happen to them.

Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals. The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.

The aim of this study is to map the consumption patterns of the poor. We also examine if loyalty can be created in this segment, and try to discover different types of poverty. This study is of great importance since the poor segment has been slightly overlooked in marketing research. Therefore we have also turned to other academic disciplines such as sociology, ethnography and consumer culture in order to analyze our empirical input. The study is abductive and we have in a qualitative and ethnographical manner conducted interviews in order to obtain information and reveal categories.

In this multistudy the aim was to measure the effect of mindfulness and yoga in negative stress. Is it possible for yoga and mindfulness to increase awareness and acceptance to inner and outher circumstances? Mindfulness-Based Stress Reduction (MBSR) has shown good results in how to cope with negative stress and how to stay calm in a stressful envirorment. The qualitative study where Visby Yoga Center and Stockholm Yoga Shakti attended in a survey. Correlation showed no relationship between stress and mindfulness and no significant value, n=20, Cohens d=0,16.

The purpose of this paper is to give a view of how violence and victims has been portrayed in novels. I have chosen 6 books where the main character is a child who has been exposed to physical, mental and/or sexual violence. I have asked questions to the book and I have tried to find patterns in the child's strategy to cope with violence and how the violence is described. I have also written two chapters about earlier studies of this field and theoretical standpoints. The main perspective I present is the salutogenese perspective and how people create meaningfulness in their lives.The children in the books have different ways to handle their situations.

The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs. Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.

In the Swedish school library discussion, the most prominent role of the school library haslong been that of cultural centre in the school, with the main goal being to encourage children'sreading. During the 90ies there were signs of a shift in focus to the role of information centre,giving active support across the whole range of the curriculum, in the independent researchingwork of the students. At the same time severe budget cuts caused great worries for the future.The interest for the school library media centres increased during this time, many differentorganizations said they wanted to fight for better school libraries. The purpose of the presentwork was to find out who they are, what they want and what their ideal school library lookslike. Fourteen organizations were studied, focus was on activities during 1995.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicin and Clinical NutritionAbstractTitle: Does supplementation of omega-3 during pregnancy affectprevalence of allergy in infants and children?Author: Peter Eliasson, Anna RahmSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 ECTSDate: 2012-04-12BackgroundEpidemiologic research has shown an association between a high intake of fish and allergy.The underlying theory is that allergy develops already at a prenatal stage and food intakeduring pregnancy has been shown to be significant. Conducting research on allergy isproblematic since it has genetic, as well as enviromental, determinants.ObjectiveThis thesis attempts to conclude and evaluate research on a connection betweensupplementation of omega-3 during pregnancy and allergic outcomes in infants and children.Search strategyThe literature search was conducted in the databases PubMed and Scopus. Among thekeywords chosen were omega 3, supplement, pregnancy and allergy.Selection criteriaHuman RCT, that measured allergy, where the intervention consisted of supplementation withomega-3 for at least ten weeks during pregnancy and ceased at birth.Data collection and analysisThree articles were chosen for this thesis. The articles were examined using templates fromSBU and the quality of evidence was evaluated according to GRADE.Main resultsNone of the articles showed a protective effect on allergic outcome but in one of the studiesthere was significant reduction in eggallergy and another showed significant lower occurrenceof severe eczema.ConclusionsSupplementation with omega-3 during pregnancy does not occur to have an protective effecton allergic outcome in infants and childen but the evidence for this is considered to bemoderate.

Layoffs may have severe consequences for organizations, and not least on the motivation of the remaining staff in the company when trying to keep on performing the given tasks. How can one with the use of rewards and goal setting affect the motivation on the remainder of the staff? This thesis is dealing with the question of how the management of Bilbolaget Nord AB, who were stricken by layoffs, are working to enhance motivation of the remaining staff with the use of rewards and goal setting. This is a qualitative case study where we have focused our attention to the workshop department at Bilbolaget Nord AB and empirics have been collected by conducting interviews with middle management executives and a questionnaire study with the remaining employees. An in-depth study of theories regarding motivation, goal setting and rewards was made in order to be able to compare and analyze the theories with the case.

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

The aim of the study was to describe parents' experiences of empty nest. The sample consisted of individuals who had experienced one child moving out of the parental home. Data were collected through qualitative semi-structured interviews and were analyzed by using thematic analysis. The thematic analysis revealed four themes, Concerns about the new time in life, Changing roles, Socializing in the family and Testing the relations. Due to the themes participants' stories reveal anxiety facing the time that will come when children takes the step to leave the nest.

The aim of this thesis is to discuss and analyse the media debate about feminist self-defence, by pointing out the pros and the cons. The arguments in favour could be separated into three different parts: statistical arguments, psychological arguments and justice arguments. The counter arguments could also be separated into three parts: general arguments, violence-related arguments and gender-related arguments. In short, feminist self-defence is built on women's experiences of men's violence. It contains three different parts to help women avoid violence, threat of violence, insult and sexual harassment.

IntroductionSuccessful training is a key for athletes to make progress in their development. Training must not just involve overload, but also must prevent the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. Too much hard exercise or too little sleep can cause overtraining, a condition in which the subject can prevent to be away from the sport for several weeks or months. Previous studies have detected that it is important to avoid overtraining.
