Hållbar utveckling i Kungsängen : ett gestaltningsarbete med fokus på folkhälsa, biologisk mångfald och ekologisk dagvattenhantering
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.
Radio i skolan : En fallstudie av ett estetiskt lärande projekt
Projektet ?Radio i skolan? riktade sig till elever inom det individuella programmet på en gymnasieskola. Det pågick sammanlagt en termin. Projektet innebar ett arbetssätt där fokus låg på innehåll, att berätta om ett ämne. Uttrycksformen för detta var att göra ett eget radioprogram.
Algoritm för automatiserad generering av metadata
Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.
Social Demokrati : Sociala medier, Politiker och Demokrati
The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .
Känsliga kvinnor och mäktiga män : En kvantitativ innehållsanalys av genus-representationen i Sveriges Radios P3 Nyheter
The radio is a medium we often listen to whilst doing something else. We wake up, do the dishes, cook or drive to work. Radio as a medium reaches many people, regardless of whether it is through conscious or unconscious listening. We thereby thought it was an important medium to scrutinize in our study. The focus of our study is on the gender representation in P3 Nyheters broadcasts.
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.
Radio som ger eko på webben : En analys av Sveriges Radios nyhetsproduktion i flera kanaler
Studien undersöker Sveriges Radios nyhetspublicering på nätet och jämför med Ekots nyhetssändningar i etern. Syftet är att undersöka eventuella skillnader i nyhetsurvalet, samt hur webbinnehållet påverkas av flerkanalspubliceringen och webbens möjligheter till ständig publicering och uppdatering, möjlighet att använda sig av bildobjekt och grafik samt hypertext och interaktivitet. Undersökningen ramas in av de teoretiska begreppen konvergens och divergens, samt teorier om hur kanalernas produktionsförhållanden påverkar nyhetsinnehållet. En kombination av kvantitativ och kvalitativ innehållsanalys har använts, där de båda kanalerna undersöktes under två dagar, 23 och 24 april 2012. Det visade sig att webbens nyhetsrapportering till viss del bestod av nyheter som inte fanns med i Ekosändningarna.

AbstractTitle: The ?Investigator? and the ?Updater? ? new patterns of news use among young adults.Number of pages: 48Author: Anna StrinnholmTutor: Amelie HössjerCourse: Media and Communications, D- levelPeriod: Fall of 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The aim of this essay is to provide an description of how daily newspaper, TV, radio and the Internet are used by young adults in order to contribute to Lennar Weibulls model ?a typology of the Swedish mediasystem from an audience perspectiv?.Method/Material: The method of gathering of empirical material has been conducted by interviewing eight people of how they use daily newspapers, TV, radio and The internet to inform themselves of the daily news. The empirical material has then been analysed by applying a two step method, of first making a summary of the interviews and secondly making a comparison with a model of Lennart Weibull ?a typology of the Swedish mediasystem from an audience perspectiv? .Main results:Two different types of ideal media users can be drawn from the empirical research, the ?Investigator? and the ?Updater?. The updater search for news to stay updated and relies on the Internet as main source of information.
Relationen mellan cyklister och fotgängare vid Södra Älvstranden, Göteborg En utvärdering av trafiken på cykelstråket Älvsborgsbron - Centrum
This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..
"Religion" i public service. Hur är det tänkt?

The study also highlights Swedens changed religious demographics and the changing media landscape. The material that is under investigation is the external and internal policy documents for Sveriges Radio, Sveriges Television and Utbildningsradion. The study is done by a qualitative content analysis which results are carved out by search units in relation to the category religion and then discussed and analyzed.
Optimering av informationsinsamlingvid prototyptillverkning
This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.
Blod, svett & tårar : En studie av vad som skapar varumärkestillknytning till träningscenter
We have examined how the dependence, identity and social bonds affect customer loyalty and attachment to a training centre. The method used is a survey on SATS Karlstad city where 128 respondents were asked, out of which 118 surveys were used in the final analysis. The data was analyzed using ANCOVA and multiple regressions.The result showed significant relationships on attachment between identity and dependence. Social bonds had no significant effect on the attachment a member have towards training centre. Customer loyalty was measured by how long the individual has been a member and his or her training frequency.
