Förvildade husdjur : möjligheter och hot

Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.

Anpassning av VOD-tjänster för breda barnmålgrupper : EN ANVÄNDBARHETSUTVÄRDERING AV BARNPLAY UTIFRÅN MÅLGRUPPEN 3-11 ÅR

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

Att arbeta med högläsning av skönlitteratur i skolans mellanår : En studie om lärares arbete med och inställning till högläsning

The aim of the study is to elucidate how teachers in middle school work with reading literature aloud and their attitudes to their working methods. The research questions concern how the teachers work before, during and after the reading aloud, and also the advantages the teachers find in their method and the obstacles they discover in the work of reading aloud. A qualitative method was used for the study, applying semi-structured interviews. The selection consists of two teachers who have worked in the profession for 23?24 years (Teachers Andersson and Bergström) and two who have worked as teachers for 3?4 years (Teachers Cederqvist and Davidsson).

Vi och dom : En granskning av hur hinduismen och buddhismen framställs i tre läroböcker för gymnasiet.

This paper examines how Hinduism and Buddhism are portrayed in three textbooks for an upper secondary school course in religion and is limited to a selection of books published in 2009. Based on a qualitative content analysis, the paper examines the extent to which there is an intentional division, that is to say a line between ?them and us? in the ways in which the religions are described, and to what extent the description of these religions in the textbooks are Eurocentric. The study focuses on whether or not there is a ?them and us? perspective in the different books and if so, the ways in which this approach is evident.The result of this study shows that traces of a ?them and us? perspective can be found in all three books.

Användarspridd reklam på Facebook : En kvalitativ studie om hur användarspridd information på Facebook uppfattas av användarna

The information which we were interested in is the one spread by normal users, and user?s perception of it. To find our results we have conducted a study in which we have used the method interview, which gives qualitative results.

Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology

In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

Standardisering av snöröjningsplan : Instruktioner, råd och tips för snöröjning av tak med stora spännvidder

The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks.

Produktionseffekter och behov av dikesrensning i Sveaskogs skogar :

Ökad efterfrågan på virke har lett till ett ökat intresse för och användande av olika produktionshöjande åtgärder. En sådan åtgärd är dikesrensning som innebär att befintliga diken eller dikessystem rensas för att de skall bibehålla eller återfå sin ursprungligt avvattnande och produktionshöjande funktion. Sveaskog avser att öka omfattningen av dikesrensning. Därför behövs en kartläggning av behovet på deras marker. På samma gång behöver produktionseffekterna och livslängden på dikena utrönas. Studien genomfördes via en studie av befintlig litteratur om skogsproduktionseffekter efter dikesrensning och dikning samt förfall och livslängd hos diken.

Dose-related selection of Pradofloxacin resistant Escherichia coli

The study evaluated the Mutant Prevention Concentration (MPC) of Pradofloxacin on three Escherichia coli (E.coli) strains, 2 wildtypes and one first-step gyrA resistant mutant. We also measured the value of AUC (Under the Concentration)/MPC that prevents growth of resistant mutants. It is of importance to reach a concentration above MPC that prevent E.coli from developing resistance against the antibiotic.We used an in vitro kinetic model where we added bacteria? and antibiotic. The culture flask was attached to a pump with an adjustable pump-speed.

Att konstruera en lag : en diskursanalys av förarbeten till sexköpslagen

The aim of this study was to identify and analyze the dominating discourse in the preliminary work of the Sex Purchase Act. In order to achieve the aim of this study we selected preliminary work of the Sex Purchase Act that was produced between 1977 and 1999. The selection is based on the fact that prostitution began to be recognized as a social problem and a gender equality issue between men and women in society. The ongoing debate during the chosen years resulted in the Sex Purchase Act, which was passed in 1999. By using discourse analysis as a methodological and theoretical approach, we have empirically studied and theoretically analyzed the dominating discourse in the preliminary work of the Sex Purchase Act.

Kvalitet och jämställdhet : En undersökning av kvalitetsbegreppets definition och dess relation till jämställdhet mellan könen inom bildkonsten

Quality is a vague concept, it seems to be about a ?gut feeling? but is used as if it were a concrete property. This paper examines the defenition of the concept of quality, the relation between quality and gender equality and also what the representation between the genders in exhibitions, purchases and donations looks like in this day. As method for this paper text analysis, with searchlight on the two parameters of quality and equality, have been used on documents that provide a historical and a cultural policy perspective. The main part of the paper is an analysis of the visual arts on Värmlands museum, Kristinehamns konstmuseum and Rackstadmuseet.In the discussion of the paper, chapter 5, the result of the research is presented.

Anonymitetens implementeringsproblem - En studie om Kortedalas försök av avidentifierade jobbansökningar

Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.

I demokratins tjänst?- En komparativ lingvistisk textanalys av nyhetsförmedlingen i Dagens Nyheter och Dala-Demokraten av EMU-valet 2003

This comparative linguistic textstudy focuses on the relationship between a newspapers own outspoken political standpoint and it´s ambition of being an unbiased provider of objective information. This connection becomes particulary interestering in times of election when a newspapers role as provider of information is of great importance for the citizens. When a newspaper reports an event to the public, the reporter always has to choose from a small selection of possible linguistic forms when representing the story. Through linguistic analysis of these forms we can see that the final choice is often not a complete arbitrary one. We compared two daily newspapers, Dagens Nyheter and Dala-Demokraten, that stod on opposite sides in the Swedish EMU-elections 2003.

Anställdas attityder till bibliotek

This paper is about employees' opinion towards libraries. The target group consists of employees at industrial research institutes in Sweden. Libraries offer several more services today than they have done before. I think many people do not recognise all of them and I also think the knowledge and the opinion about libraries have to do with use of them. Since I am curious about if this is true or not the purpose of this essay is to find out, through an attitude research, the employees', at industrial research institutes, opinion about library service.

Med hästen som pedagog, mentor och kamrat : En studie av hästar inom den djurassisterade pedagogiken samt deras betydelse för skolungdomars personliga utveckling

Djurassisterad pedagogik har flera tänkbara tillämpningsområden i skolan. Djur har visat sig inverka positivt på den sociala miljön i skolan. Djur har en positiv effekt på elevernas koncentrationsförmåga, motivation och problemlösningsförmåga. Det har också visat sig att inlärningen gynnas, barn som får lära sig att läsa för en hund lär sig snabbare. Djur är också effektiva hjälpmedel då barn utvecklar sin empati, särskilt för pojkars empatiutveckling.
