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.

Background: Earlier studies show that nurses work environment is a factor that may affect the quality in nursing care negatively. Other factors are: number of employees, working hours, work structure and planning and working relationships between colleagues. Work relationships are particularly important for nurses as they can affect patient safety. Nurses are prone to stressrelated illnesses and high stress levels prove to have a negative affect on the quality of nursing care. To develop and assure the quality demands effort from every employee.

This study is based on interviews with five directors of educational administration within the Stockholm County. The purpose is to investigate how the directors of educational administrations, in the different municipalities, describe the relationship between the administration and the local school units. Moreover, the aim is also to describe the administration director?s work in relation to the various levels of the administration. To what extent can it be identified as a dimension of the learning organization described in this report.The study shows that skepticism is usually directed upwards toward the next level in the organization and that the decision-making right for local schools is consistently safeguarded.

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

The purpose of this thesis was to increase our understanding of how the social service in Sweden deals with reported incidents of addiction to medicines. Another purpose was to point out the different opinions concerning addiction to medicines amongst actors as well as possible ways to handle the problem.We have conducted a quantitative and qualitative e-mail survey targeting all communities in Sweden, with the ambition of gaining further knowledge about the role and responsibility of the social service concerning reports of addiction to medicines. Two quantitative questions were one asked about how many clients requested/were reported for needing help with their drug abuse alone, and the second question about how many clients needing help for drug abuse as a part of a wider addiction.The survey revealed that the social services judge their role/responsibility differently; some take the main responsibility while others think that drug abuse is created by the general health care and should be handled by this organization as well. In relation to the estimated amount of drug addicts in Sweden only a small part are in contact with the social service..

How does music teacher work in class with traditions in the school's world?I sent out 53 questionnaires to music teacher that works with music in class, in order to find out what the school learn the students about our traditions. When I put together the questionnaires and the background material, I come among other thing until that three fourth dividing off the examined the music teachers do not appear to leave off some folded contained Lucia- and the Christmas tradition. Those music teachers who replied on the questionnaire seem not to notice the immigrant?s traditions.In this exam work has I also overall and put together background materials, as among other things points on the value of traditions.

This bachelor´s thesis analyzes the video game Red Dead Redemption and the historical use of the environment and atmosphere in the game. The theory and method used is media research and social memory studies. Two questions were asked: how does Red Dead Redemeption convey and produce the historical environment and the historical atmosphere. Furthermore subqueries/criterias were used to help answer the main questions.The analysis was divided into two parts, the first part we analyze and discuss the games historical environment and the second part analyzes and discusses the historical atmosphere of the game.The conclusion is that both the historical environment and the historical atmosphere is present in the game through picture and sound, the text only works as a guide. The picture and sound live in a symbiotic relationship and depend on each other to fully immerse the player to the game.

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.

The elderly care is an area of great importance to women. Women are more often in need of elderly care; they work with the service and provide a majority of the informal service. Research shows that managers? work-related prerequisites are significantly different between the male dominated technical administration and the female dominated care and educational administration. Studies also show that what the highest managerial organisation gives priority to, often permeate the whole organisation.

Assessing the outcome of corporate responsibility is often argued to be complicated due to long-term effects and qualitative aspects. Epstein (2008, p.261) establishes that: ?Though many think that sustainability is too difficult to measure, companies have found that unless the impacts are measured, they are commonly ignored in the resource allocation process?. Corporate responsibility is often referred to as a business case, i.e., that social and environmental concern add value to the business (Heikkurinen, 2010; Porter & van der Linde, 1995). Hence, for corporate responsibility to be a business case a strategy, corporate structure and systems, programmes and actions linked to performance measures need to be in place to assess the outcome; environmental, social as well as financial.

The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage.  The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment. The result for the portfolio consisting of stock recommendations show a positive return of equity in positive environment and the opposite effect in negative environment. The pattern that has been observed can be classified as an anomaly.

Arbetsmiljöverket har under 2008 och 2009 gjort inspektioner hos Hudiksvalls kommun. Arbetsmiljöverket konstaterade i samband med dessa inspektioner att chefer och arbetsledare saknade kunskaper om arbetsmiljölagen och dess föreskrifter. En utbildningsplan inom kommunen var lagd under 2009 för att rätta till dessa brister. Hudiksvalls kommun har en önskan att veta om utbildningen i det systematiska arbetsmiljöarbetet gav förbättrade kunskaper inom området. För att ta reda på om utbildningen gav förbättrade kunskaper har en undersökning gjorts mellan två grupper, varav den ena inte har gått arbetsmiljöutbildningen.

AbstractThe Swedish society has always been monolingual, but has for the past decades transformed into a multicultural and multilingual society. The aim of this study is to investigate if and in that case how preschool teachers work with language development in bilingual and multicultural preschools. The concept of linguistic and cultural diversity includes several different components, not least the social interactions that are of great importance to every individual's development, learning and participation in the world. By understanding the importance of language, language development and the role of mother tongue in second language acquisition, we look into various researches done concerning the effects of the preschool teachers? opinions, methods used to language developmental primarily for children who are multilingual and how the physical environment is shaped to promote language in multicultural and multilingual preschools.The method used in this study is semi-structured interviews with preschool teacher working in multicultural or bilingual preschool settings.

Ett av Sveriges största folkhälsoproblem just nu är den dramatiskt ökande sjukfrånvaronpå våra arbetsplatser, vilket drabbar både individer och samhället i stort. Det är därför viktigt att skapa hälsofrämjande arbetsplatser. Studiens syfte var att undersöka vilka faktorer personalen på en kommunal förvaltning anser kan bidra till att deras arbetsplatser blir mer hälsofrämjande. Vidare syftade studien till att undersöka personalens syn på hur förändring och lärande kan ske på deras förvaltning för att skapa hälsofrämjande arbetsplatser. Datainsamlingen har skett genom fyra fokusgruppsintervjuer med anställda inom en kommunal förvaltning.

The aim of this study was trough qualitative interviews with teachers and counsellors in Swedish schools, to study their experiences and perceptions of non suicidal self-injury (NSSI) in adolescents. During the study three teachers and three counsellors who worked in four different schools were conducted. The theoretical approach that was used is Michael Polanyis theory tacit knowledge. The outcome of the study was that schools did not seem to talk about NSSI as a problem and the teachers knowledge about it had come from own experiences meeting adolescents whit NSSI. The interviewed teachers and counsellors felt it hard to define NSSI, they mainly referred it to someone who cut themselves.
