Hästar i skrämmande situationer : en jämförelse mellan hanterad respektive fri habituering

In connection with riding and handling of horses, many accidents that can cause severe injuries to both horses and humans are existent. The cause is in most cases that the horse is frightened. The horse's fear also affects its usefulness and it has been shown to have adverse effects on the horse's welfare. To increase safety and improve the welfare of both humans and horses, it is important to find appropriate training methods to reduce the fear of horses in frightening situations. This experimental study compares handled habituation to free habituation.

Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

Uppvärmningssystem : Ekonomi, miljö och drift

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Mänskliga rättigheter vid en naturkatastrof : En jämförelse mellan Haiti och Thailand

There are three main purposes for this thesis; the first is to distinguish the possible violations that can occur in time of natural disasters. The second is to analyze if there is a correlation between political systems and how the effected country handles the aftermath of a natural disaster. The third purpose is to determine the role of the global community and what responsibility lies with them. The issue is often that the aid becomes the main object for discussion and analysis, but the focus rarely shifts to the effected State. Therefore the focus in this essay is the political system and how they cope with the human rights violations that can occur in a time of natural disaster.

Barn söker i bibliotek ? en kunskapsöversikt

The aim of this thesis is to investigate new knowledge about how children search for library material and which strategies they use, and if the latest research gives any answers whether we should adapt systems and services or teach information seeking in a better way. In this thesis knowledge is understood as research publications but also results from projects in library practise, and studies concerning children 6 to 18 years old are included. The method used is a knowledge survey. We have gathered and evaluated documentation from different sources like citation and reference databases within the field of library and information science. The result implicates that there are, both in old and new documentation, three main search strategies children use in their search for information in a library context; they browse, they search in library catalogues and they use some sort of reference service.

Härskarens nya kläder : Vad händer när härskartekniker flyttar in på Facebook?

In this thesis we focus on the issue of master suppression techniques and how they take form on Facebook. The research in area of master suppression techniques online is limited and therefore the purpose of this thesis is to create a greater understanding of the online environment of Facebook. We have used a method of netnographic observation studies and content analysis to create a triangular perspective of the subject. Based on the result of our observation studies we draw the conclusion that you can see signs of some of the master suppression techniques on Facebook. We also argue why others don?t show up.

Användarrelaterad energieffektivisering : En studie på länssjukhuset i Sundsvall

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.

Barbie Feminist eller förkastlig förebild? En diskursanalytisk studie av en populärkulturell ikon.

The Barbie doll is an icon filled with meanings; this thesis discusses the Barbie doll and herfeministic potentials and subject positions using a discourse analysis. The thesis analyzeswhat sort of femininity Barbie portraits in magazines, web series and films about her.Theories being used originate mainly from gender and queer studies, where the focus is on theperformative constructions of gender and femininity. Since the material mostly consists ofmoving images some influence is taken from feminist film theorists and semiotic theory,which focuses on signs and their meaning. The thesis centres around the questions: how isBarbie?s femininity challenged, strengthened and constructed in different types of mediaabout her produced by Mattel? And is there any feminist potential in Barbie?s subjectpositions in these media forms?.

Fastpris med Dynamic Systems Development Method (DSDM) : Fungerar DSDM som projektstyrningsmodell i fastprisprojekt?

Enligt Standish Group är det endast cirka 35 % av alla systemutvecklingsprojekt som avslutas på ett lyckat sätt när det gäller tid, budget och resurser. Inom systemutveckling är fastprisprojekt, där systemets kostnad är förbestämd, allt mer populärt. Dynamic Systems Development Method (DSDM) är en modell för utveckling som fokuserar på fasta resurser och tid med funktionalitet som den flexibla variabeln. Syftet med den här uppsatsen är att se om man kan driva fastprisprojekt med en modell som DSDM på ett sätt som gör det till en bra lösning för både beställare och leverantör.Min slutsats är att det största problemet med DSDM är att få beställaren att godkänna den som projektmodell. Ett annat stort problem är att många projekt med DSDM blir stressiga eftersom tiden är fast.

Lärares genusmedvetenhet : En kvalitativ studie om idrottslärares beaktning av genus i undervisningen

Semi-structured interviews were employed as method for the data collecting process. Four teachers were interviewed, teachers of PE in elementary and upper secondary school with varied length of professional experience and ages.

Webbsystem för matprisjämförelser

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
