It is often challenging to create a new enrichment program for any animal. This is especially true with the additional challenge that I wanted to use only naturalistic enrichment, and I?m working with animals some of which are nocturnal. Even with a many hurdles, a little bit of enrichment can do a big difference and make a big difference in activity levels of the animals. Eskilstuna parkens zoo have a house called the MUSeum housing four kinds of rodents.

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

In today?s world urbanisation is an on-going process, cities are growing and becoming denser, and places for recreation gain value. Therefore, urban parks are much appreciated by people living in cities. When the first public parks where planned, their main function was to increase health, hygiene, education and social life. In the middle of 19th century the meaning of public parks to people?s wellbeing gained attention and parks were planned to provide space for lively activities. This paper focuses on parks? activities.

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

Title: "It is logical, but not logical at all compared to every other logical thing." - A study about how students in upper secondary school reflect about their studies in Pitch and music theory.Pitch and music theory is a compulsory subject for music students in the art programme of upper secondary school of Sweden. The aim of the subject is to develop the students? knowledge about music theory concepts in order to help them play and create music on their own. The aim of this paper is to discuss how students talk about ear training and music theory. Qualitative group interviews were carried out with two student groups from the first and second year of the upper secondary school.

The purpose of this essay has been to examine whether attitudes and behavior among Swedish people who takes snuff are dissonant or not and how their attitudes are affected by the media debate about the health risks snuff can cause. Furthermore, we were interested in finding out how different reference groups´ attitudes would influence the attitudes and the willingness of people to stop taking snuff and investigate how much control the people who take snuff think they have. To answer these questions we chose to ask primarily students at Stockholm University and Södertörns Högskola. The students were asked to fill out a questionnaire with 22 questions and the 100 responses we collected were worked up in a statistic program, SPSS, on the computer. The main models used for the essay and for the questionnaire were the Theory of Planned behavior and the Dissonance theory.

Service delivery acts like a process. This can enable the possibility of attracting attention towards the company who?s making use of this, furthermore generate several opportunities. However, it?s far from easy to deliver new services.

In this thesis swedish students? worldsviews, in relation to the theory of evolution, were studied. Thirty students from two different schools and cities took part in the survey and four students were later chosen for interviews. The results showed that there are many different types of students and categories in this matter. The study also showed that for some religious students, accepting the theory of evolution was not difficult thus showing that religious students can both believe in God and in the theory of evolution..

This paper deals with the question of neolithisation of Southern Scandinavia. The main goal is to give an overview of three theories regarding how agriculture and livestock breeding was introduced to the Southern Scandinavia. These are as follows: the immigration theory, the socio-economic theory and the historical explanation theory. Furthermore it is investigated which theory has the most probably support in material culture. There are obvious difficulties in interpreting the archaeological material.

I denna studie testas tio hypoteser som relaterar till finansiell teori för att se hur väl teorin kan förklara skuldsättningsgraden i små börsnoterade bolag. De teorier som testas är avvägningsteorin (trade-off theory), hackordningsteorin (pecking order theory) samt teorier relaterade till asymmetrisk information och agentkostnader. Testen genomförs med multipel linjär regressionsanalys och de undersökta bolagen är samtliga bolag med färre än 200 anställda på tre av de mindre börslistorna i Sverige. Resultatet visar stöd för åtta av de tio undersökta hypoteserna och är i flera avseenden tydligare än i tidigare studier som testar onoterade små bolag eller ett bredare urval av bolag..

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

New laws and recommendations within corporate governance during the last years have affected the way board of directors work. The board is said to have and fulfill three roles: a control role, a service role and a strategy role. These roles could be understood by three theoretical theories: the agency theory, the resource dependence theory and the stewardship theory. The purpose of this study is to investigate whether, and if so how, the board work differs between two small firms based on these roles, given that one of the firms is a publicly listed firm and the other is a privately owned firm. Using a qualitative case study as research method we find that the board work differs between the two companies when it comes to these roles.
