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.

Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989). Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).

Background: A company?s choice of capital structure is influenced by the access to internal and external capital but also by the opportunities and threats that the management perceives in the environment and the management?s attitude towards risk. How an individual perceives and interpret the environment depends on the cognitive structures, which are shaped by personality, background and earlier experiences. Accordingly cognitive structures can be expected to influence the choice of capital structure. Purpose: Out of a cognitive perspective we intend to study the relationship between the way a company views it?s environment and what capital structure it chooses to have, in order to contribute to an increased understanding about what lies behind a company?s capital structure policy.

På Svenska Gymnastikförbundets begäran har detta projekt gjorts som ett koncept för dem att ha som utgångspunkt i diskussioner med såväl föreningar som politiker i frågan om gymnastikens behov av anpassade idrottsanläggningar.En användarstudie av gymnastiken, samt flera discipliner, har gjorts och stått som utgångspunkt för anläggningens utformning. Därtill har även en utvärdering av flertalet befintliga hallar som används för gymnastik gjorts för att motivera beslut gällande anpassningar som lyfter anläggningens utförande i jämförelse.Arbetet kommer ge en skriftlig rapport och en digital modell av anläggningen. Modellen presenteras i form av ritningar och visualiseringar..

A  brief review of computer and Internet history attempts to explain the formation and evolution of social media. Risks in terms of risks related to leadership and risks related to IT-security are taken into consideration and have been briefly explained.

Introduction: In this study an innovative and multimodal method in family therapy called NVR, Non-Violent Resistence, is examined. NVR is an approach developed by Haim Omer, professor in psychology at the University of Tel Aviv. This approach is described as coming from the ancient ideological roots used by Gandhi in the Nonviolent resistence of oppressive regimes. NVR advocates that the parents give up the desire to control their children. Instead parents should take control of their own lives by actively resisting any behaviors of the child that are damaging.

The main purpose of this master thesis is to investigate in what ways library and public preschool cooperate with families with immigrants background in developing and protecting children's languages and cultures in two districts, Hässleholmen and Norrby, in the community of Borås. I want to investigate the parent's meaning of view according to which roles the libraries and public preschools involvement play. The study is based on qualitative interviews. Nine interviews were undertaken with parents who live in these two districts and five interviews with the librarians and preschool teachers who work in the libraries or the public preschools. The study of relevant literature, which describes topics such as psychological aspects of immigration, facts about children with immigrant's background and their language development and multicultural librarianship, provides a basis for the discussion.

 Background and aim: Media development and digitalization has expanded the PR industry's working area. More participants are on the media market and it is becoming more and more difficult to define what PR really is and what the PR agencies/departments really do. Is PR marketing, information, event marketing or maybe propaganda? We believe that the complexity to define the term PR can lead to a loss of critical approach to the business, especially among young people. Has the PR industry managed to eliminate their negative image among students in upper secondary school and what do they associate with PR today? The aim of this essay is to examine what a selection of students associate with the term PR and if they are critical to the PR industry or not.Method/Material: The method is a quantitative survey.
