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.

The purpose of this study was to examine the usage and occurrence of media literacy in relation to literature studies in the senior level of the nine-year compulsory school. The questions at issue were;How do teachers and students look upon media literacy and how is this attitude reflected in their education?How do teachers incorporate media literacy with literature studies?What attitudes do students have towards their teachers? education of media literacy and literature studies?The study took place in two cities in Sweden. It consists of eighteen qualitative interviews with six teachers and twelve students. The study shows that teachers have different attitudes towards media education in relation to literature studies.

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

This essay contains explanations of what dyslexia is. It has concreate suggestions of how to plan and how to work with students with dysfunction. The focus on previous studies in the field of dyslexia is narrowed down to generally Swedish studies..

Detta är en uppsats med syfte att analysera och motbevisa den allmänna föreställningen om att endast högerextremister och Nationalsocialister begår hatbrott. Detta görs med hjälp av frågor som, varför existerar denna föreställning? Vilka antaganden tas i ett sådan föreställning? Vilka är motargumenten? Med hjälp av en diskursanalys, analyseras rapporteringen av ett hatbrott från ett antal tidningsartiklar, för att på så vis kunna visa hur media osynliggör de personer som utför hatbrott men inte definierar sig som extremister. Vidare handlar uppsatsen om ett upprätthållande av heternormativiten dels genom hatbrott men även konstruktionen av det avvikande..

The objective of this study was to investigate the attitude towards African swine fever (ASF) primarily among smallholder pig farmers but also among other actors along the pork value chain in Gulu district, Uganda. More specifically, the study aimed to investigate the specific challenges facing both farmers and other members of the pork value chain using participatory epidemiology (PE). ASF is a feared viral disease of pigs associated with high mortality, which is endemic in many parts of Africa. The recent history of Gulu district in Northern Uganda can be described as turbulent and the human population has suffered during decades of war and civil unrest. Pig keeping is considered a potential opportunity for business as well as a way of providing more animal protein in the diet. However, this is threatened by ASF as farmers can lose entire herds due to the disease. This study can confirm some previously known factors and risk activities such as the free range system of pigs and movement of pigs and pork during ongoing outbreaks, which make disease control difficult.

Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.

Två begrepp som ofta diskuteras inom organisationsteori är Medarbetarskap och Human resource management. Personalen ses ofta som ett företags främsta resurs. Denna uppsats bygger på en kvantitativ undersökning bland personalen inom en Telekomkedja. Vårt syfte är att bringa klarhet i frågan om i vilken utsträckning det ?myndiga medarbetarskapet? existerar, hur olika strategiska åtgärder påverkar försäljningen, vad som påverkar medarbetarnas motivation samt hur deras lojalitet gentemot arbetsgivaren ser ut.Undersökningen visar att personalen i Telekomkedjan trivs bra på sin arbetsplats.

The aim of this study was to describe the prevalence of gingivitis, periodontitis and dental caries in individuals with type 2 ? diabetes. The study was conducted in a form of a general literature review with the restricted to the following conditions: human studies, English, and articles published between 2007 - 2012. Articles lacking a control group were excluded. The data were collected through searches of the medical database PubMed. A compilation of 11 scientific articles was examined.

The present paper is part of a project carried on by the Swedish Section of the International Commission of Jurists. Sweden has ratified several major international human rights instruments. Most of the rights are covered by national law, and only in exception is there a discrepancy between national and international law. Such a discrepancy is found in the UN Convention on the Elimination of all forms of Racial Discrimination, in which the State parties agree on penalizing and prohibiting the founding of and participation in racist organizations. Sweden is not complying with this statute, despite the fact that the government has ratified the convention.

The castle Vivesholm is located about two miles north of Klintehamn on the west side of Gotland. The castle was built around year 1395 and burned down in the end of the 14thcentury. Around the 17th and the 18th century the castle was re-used. However, the emphasis on its use is during the middle ages.This paper aims at getting an insight in the animal husbandry at Vivesholm by analyzing the osteological material. The analysis revealed that bones from sheep/goat were more common than bones from cattle.

This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

What gives a place meaning for it?s users? The intention of this paper is to investigate how landscape architecture is able to form places that evoke involvement from it?s users. Ideas within architectural theory such as territoriality space and place is being explained and used when analyzing several different case studies. The places for my case studies are all distinct in their expression and can all most be treated as objects on their own. In my case studies I came to the conclusion that a designer can work in many different ways to create a site that appeals to it's users, but that it is the sites that allow users to interact that become meaningful places..
