With an increasing production of biogas follows an increased amount of digestate. This could potentially be a valuable source of fertiliser with the destruction of weed seeds as a possible advantage. However, there have been some concerns regarding the product still containing viable seeds of weed. In this Bsc thesis the results of previous research on the fate of weed seeds in biogas production is summarized. It is also a comparison of research on the effect of similar processes such as silage, compost or animal passage on seeds. The purpose of this is to evaluate risks of spreading viable seeds, potentially problematic species and perhaps to find out how to eliminate the risks. The literature review revealed that previous research mainly indicates low risks regarding many of the tested weed species, but not all studies show the same result, therefore extended research on the subject is desirable.

The disciplinary role of madness in the European society was major during the17th century rise of the national state.By studying the view on madness in Swedish governmental investigations duringthe modern years of the Swedish psychiatry, 1950 to today, it's possible to seehow madness function in society have changed. The study is based on a discourseanalysis and done in three important aspects of Michel Foucault's philosophy:terms of existence, control and knowledge.Based on Foucault's theories of self-discipline, exclusion mechanisms and adetailed investigation on the concept of power, the empirical survey shows howthe ?crazy? Swede changes from a disciplinary object of society into a drone toserve under the structures of capitalism. In a psychological condition previousscience has judged as animal..

The quest to determine if non-human animals have emotional lives similar to man goes a long way back and is yet to result in a clear answer. The aim of this particular literature study is to determine whether or not the African elephant may host feelings of empathy and display altruistic behaviour. In search for an answer to this question, scientists have chosen to first evaluate the cognitive abilities of said species. They have done this through the testing of tool use, mirror self-recognition, memory and the ability to coordinate with another when performing a task etc. It is generally thought, that in order for complex emotion to exist within an individual, cognition, as an awareness of the self and others, must first be present.

In today's social work there is an ambition to work evidence-based in order to improve quality and competency in business. This study is made in a disability administration which has introduced a common approach towards users for all employees. The approach is called low arousal approach. The purpose of the study is to investigate how a method takes hold and implements within an organization. The empirical data is analyzed by theories of professionalization, idea dissemination and translation.

Prior research in human bird relations is relatively small and discussion about bird ecology in relation to humans is largely not discussed. The study means to understand how a difference in usage of birds and symbolization of a bird occurs. This will be answered through analysis of two bird species. The study uses three different sources of material to conclude its answers. The sources are graves with bones of predatory birds, material culture representing bird motifs and historical sources discussing mythology.

Assessing the emotional state in animals is important in order to establish the quality of their welfare, therefore it is important to investigate under what circumstances animals experience these emotions and to find indicators of their existence. The aim of this thesis was to detect possible behavioural indicators for positive emotions in dogs. These behavioural indicators could be helpful to increase both dogs? and humans? overall well-being in today?s society since they could help e.g. dog owners and caretakers to interpret behaviours displayed by dogs and their intentions so they can respond accordingly.The subjects used were 9 research beagles and each dog participated in three different treatments, assumed to be experienced as positive situations, where communicative interaction was initiated with the dog by engaging in 1) physical contact (P), 2) verbal contact (V) or 3) both physical and verbal contact simultaneously (PV).

Flexicurity is a union of the English words flexibility and security. The union of the two words to one common term, hints that flexibility and security does not have to be each others counterparts in order to achieve good economical development and employment. Flexicurity, as it is found in Denmark, is described as a three part model composed of active labour market politics, generous financial compensation in the case of unemployment and flexible labour law. The existence of strong collective agreements and three part cooperation is of great importance for the good flow of the Danish model. The same goes for education of different kinds.

The purpose of our study was to look at the connection between theories, research work and concepts when it comes to teenagers and the testing of drugs. The theories we have used are Erikssons development theory, psychoanalysis and labelling theory. Concepts that we focused on for our study were youthculture, the search for identity and the testing of drugs. We did this by asking students, in ninth grade, to fill in questionnaire and interviews.Teenagers find themselves in a confusing stage in life and in a search for their identities they test many different things. The youthculture can be a contributing factor to them testing drugs.

This paper is about drug prevention. In my paper the aim is to examine when, where and how the drug prevention work, by law, is being realized, on local levels, in school and municipality, towards youth.My central questions are among others: What does it imply, how the municipality and school value the drug prevention work?, Which prevention programs do the municipality and school use? and Does the drug prevention work give any results? The method I've been using is qualitative interviews and studies of literature and research.The main results I gained with my studie are, that the work of politicians is not in phase with the development in society. And in spite of the fact that drug prevention programs are used, the young ones are using drugs and alcohol more than ever..

The purpose of this essay was to examine teenager's views on violence among young people.Our main questions were: What kind of views on violence among young people do teenager's have? What do teenager's think about what causes violence among young people? In what way does scientific knowledge confirm young people's views about what causes violence among young people?To answer these questions we designed a questionnaire which we distributed in three 8th grade classes. We also interviewed five teenagers about violence among young people, to get a deeper knowledge about their views.The results of this study show that the teenagers think that violence among young people has increased and that the violence mostly appears between different groups of young people. The teenagers also think violence among young people as a phenomena due to different kind of reasons..

SammandragJag har analyserat hur hundkläder presenteras i tre svenska e-shopar. Inspirerad av det relativt nya fältet Human Animal Studies ville jag undersöka hur hundens kön, ras och subjektsstatus görs. Jag använder diskursanalys av texters och bilders samspel.Det är få hundplagg i min analys som uttalat sägs vara för tikar eller hanar men en möjlighet att markera kön på sin hund finns ofta närvarande i och med färger eller tryck Tik- och markeringsskydd, som är avsedda för ena eller andra könet, uppvisar också skillnader. Dock verkar även en något feminin klädsel vara accepterad för hanar och det mönster jag tycker mig se av att mindre, mer pälsklädda raser framställs feminint är inte entydigt.Kontroll av hunden verkar förhandlas genom att vikten av bekvämlighet poängteras. Jag drar därmed slutsatsen att hunden ses som subjekt men visar att det är på ett antropomorfistiskt sätt där människor tillskrivs föräldrarstatus.

Detta är en studie av ungdomars syn på diskriminering. Syftet med vår undersökning är att undersöka vad ungdomar anser att diskriminering är. Tidigare forskning visar att diskrimineringsbegreppet kan vara svårt att definiera och att ungdomar inte har kunskap om begreppets fulla innebörd. Våra kvalitativa intervjuer med sex ungdomar visar att diskrimineringsbegreppet är svårt att definiera och att deras definition av diskriminering stämmer överens med delar av barn- och elevskyddslagen. Med hjälp av teorier om intersektionalitet kan vi se att ungdomarna inte har tillräckliga kunskaper om vad diskriminering är och detta medför att de inte vet sina eller andras rättigheter inför barn- och elevskyddslagen..

The aim of the essay was to describe what some young Swedish and Spanish people had to say about alcohol cultures. Some of the questions asked were: How are the alcohol cultures in Sweden and Spain described? What are the differences, and where do they come from? What would an ideal alcohol culture look like? The investigation also had a comparing angle, as I was interested in what the people valued in their own culture and in the others´. The result was that there hardly exist a perfect alcohol culture, but that the stricter Sweden as well as the liberal Spain both have positive and negative aspects. Differences in politics and culture seem to create variations in a society´s drinking customs.

Purpose There are almost infinite numbers of ways to build dairy farms in Sweden. When building a new free stall barn you have the possibility to affect both working environment and Animal welfare for many years to come. The construction costs are influenced by which type of barn that is built and what functions it contains, for example one can predict that automatic milking systems are more expensive to integrate than milking parlours. But what is the real cost of today for the construction of free stall barns with milking centres and how is it affected by construction methods and functions? Is the labour time influenced by the building costs? These are some of the questions this report will try to answer.

This thesis analyzes the consequences of ?Lex Uggla? ? a law concerning the boundaries between firm and individual with respect to wealth taxation ? for small businesses, with more than 3 million SEK in over-liquidity. There are two main findings of this thesis. Firstly, the wealth taxation of non-operational assets seems to be an inefficient tax which costs the Swedish welfare system much more than it generates. Secondly, the change in actions among entrepreneurs following the extensive news coverage following the tax authority?s charges against the company of the well-known artist, Magnus Uggla (hence ?Lex Uggla?) illustrates that neither changes of rules nor new applications of rules is necessarily sufficient for an agent to change course of action.
