Informationsförsörjning för nya högskolor : En modell för Helsingborgs högskolefilial

In this work we study how the information provision should be organised in a new smaller size Swedish university college in a town without previous academic traditions. Specifically, our aim is to propose a possible model for information provision in Campus Helsingborg which is currently under construction. The study consists of two parts: literature review and empirical investigation. In the literature review we summarise a selection of articles about traditional and untraditional practically realised ways of information provision in nineties. The empirical investigation consists of 19 interviews with students, teachers and librarians from Kalmar, Halmstad and Helsingborg.

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.

Demokrati i skolan - en studie av ett urval lärares undervisning om demokratibegreppet

Demokratibegreppet är för många elever ett ord som innebär enbart rättigheter. Begreppet tolkar de ofta som att demokrati innebär att gå och rösta.Denna uppsats syfte är att belysa hur So-lärare på högstadiet undervisar om demokratibegreppet, för att eleverna ska få en förståelse för begreppet. Uppsatsen ska ligga till grund för reflekterande frågeställningar för oss blivande lärare och verksamma lärare.Olika litteraturteorier och perspektiv på demokratibegreppet har studerats i anknytning till uppsatsen. Vi har i vår studie intervjuat sex olika lärare på högstadiet.Resultatet av studien visade att lärarna har goda kunskaper om vad demokrati innebär i sin undervisning. Samtidigt kan det konstateras att demokratibegreppet behöver lyftas fram ännu mer i skolans sammanhang för att medvetandegöra innebörden för eleverna..

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

In this Bachelor?s essay we discuss whether eWOM (electronic word-of-mouth) is perceived as advertisement or as normal information, which is not influenced by any company, on the platform Facebook. 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.

Nedskrivning av koncernmässig goodwill under global finansiell kris

Inledning: Sedan i januari 2005 är alla bolag som är noterade på börsen inom EU skyldiga att upprätta sin koncernredovisning i linje med IFRS. Koncernmässig goodwill skall inte längre avskrivas enligt plan utan istället bör en nedskrivningsprövning utföras varje år enligt IFRS 3. Den finansiella krisen, som tvingat oss in i den lågkonjunktur vi befinner oss i idag, är en effekt av en tidigare världsomspännande galopperande kreditexpansion. Denna fick stora negativa ekonomiska konsekvenser främst på kapitalmarknaden i USA. På grund av USA:s ledande position inom många områden har detta satt djupa spår i hela omvärlden.Genom att noterade bolag enligt IFRS redovisningsprinciper skall redovisa en rättvisande bild av företagets finansiella ställning gjorde vi ett antagande att frågan om en eventuell nedskrivning av koncernmässig goodwill bör ha aktualiserats den senaste tiden. Syfte: Vårt syfte med undersökningen var att se om och i vilken omfattning bolag har gjort nedskrivningar av koncernmässig goodwill under 2007, 2008 samt första kvartalet 2009. Metod: Vårt slutliga urval blev 60 bolag noterade på Stockholmsbörsen.

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.

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.

Mot en stadig tillvaro : En utvärdering av den kontaktpersonbaserade insatsen Perrongen i Uppsala kommun

Den här uppsatsen är en utvärdering av insatsen Perrongen i Uppsala kommun. Perrongen är en kontaktpersonbaserad insats med integrerat nätverksarbete. I uppsatsen har Antonovskys (1991) KASAM använts som teoretisk bas. Datainsamlandet har skett genom att åtta respondenter, som tidigare haft Perrongen som insats, har svarat på varsin enkät samt deltagit i varsin intervju. Resultaten pekar på att respondenterna i huvudsak uppfattat insatsen Perrongen som positiv, vilket stämmer överens med tidigare forskning.

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.
