?Den stojande hopen? : Diskurser om ungdomar i två bibliotekstidskrifter 2005?2010
The aim of this thesis is to examine discourses about the user category young people in two well-established Swedish library journals between the years 2005 and 2010.The empirical material consists of 65 texts derived from the library journals Biblioteksbladet and Bibliotek i samhälle. By using discourse theory and methodology I discover several different ways in which young people are categorized in the library context. As a complementary theory I have analyzed the material from an intersectional perspective. The result shows that young people most of the times are defined by adults. Several characteristics such as creativity, interest in modern technology, messiness and need for support are repeated in the descriptions of the young, suggesting that there is clear idea of how young people are.
Påvisande av Helicobacter spp hos hund : en metodologisk studie
The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs.
Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.
IKT verktyg ? befrielse eller belastning? : Elever i behov av särskilt stöd och deras uppfattningar om IKT verktyg i lärandet.
The aim of this study was to describe and analyse the perceptions that ten 12-15 yearold pupils with special educational need, who had been assigned a personal computer, have about Information and Communication Technology (ICT) in the learning process. Data was collected by personal interviews and observations. Sociocultural perspective and phenomenographic research approach were used as theoretical and methodological frameworks in analyzing and understanding the result. The major conclusions were that most respondents perceived the computer as beneficial assistive technology for learning, but some felt singled out by having a computer to assist in learning. Students had various opportunities to succeed in using their tool depending on e.g.
Vad innebär digitalisering av kulturarvet? En ideologianalys av tre svenska digitaliseringsprojekt
This Masters Degree thesis aims at giving an answer to what underlying ideologies are at work in digitizing our cultural heritage. Other questions to be answered are who are benefiting from a digitized cultural heritage and who are not, and what different opinions about digitizing our cultural heritage can be identified. Two studies are made in this thesis, one of Swedish political documents that concern digitizing our cultural heritage, libraries, museums and archives, and the other one is a study of documentation of three Swedish digitizing projects. In the first study three different, but closely associated ideologies are identified, namely a preserving, b giving access and c a mixture of both, and these are shown in a model. In the second study this model is then used to identify the ideologies of one project from each sector of the so called ABM-sector Archives, Libraries and Museums.
Variationen i användandet av IT-verktyget Trade : En fallstudie hos NCC
Companies that are facing the global market are put in to new challenges in order to streamline its business. One industry that has realized that changes are necessary is the construction industry, it is an industry witch is far behind the development of introducing information technology-tools systems in there business. It has shown there is a relation between high IT usage and high productivity, which is one of the reasons to why companies in the construction industry should purchase a business system especially for procurement. However, companies that have purchased a business system are facing difficulties in having their employees using it for its purpose. People react differently to changes and that?s why variations in quantities exist for usage of information technology-tools.
Muntlig formativ kamratbedömning som kommunikativ praktik : En designbaserad studie i det naturvetenskapliga klassrummet
In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.
Störningsindikation på lågspänningsnät
Föreliggande rapport är avsedd som ett examensarbete i elektroteknik (20p).Syftet med arbetet är att skapa en applikation för att finna störningar pålågspänningsnätet upp till 95kHz. Bakgrunden till arbetet kommer frånenergibolagen som vill kunna skicka datainformation direkt pålågspänningsnätet, detta vill de kunna göra med hastigheter mellan 2k ? 5kHz. Beroende på med vilken hastighet man vill skicka information kan störningar mellan givna frekvenser hindra datatransmissionen, därför är detviktigt att hitta vid vilka frekvenser störningarna uppstår så att lämpligaåtgärder kan vidtas.Grundläggande delar i applikationen är ett oscilloskop för mätning, dator medGPIB- kort för upptagning av data och LabView programvara för hantering avdata. För frekvensanalys kommer Fast Fourier Transform, FFT, att användas,varvid en grundläggande beskrivning kommer att medfölja..
Isaac Newton och den matematiska naturfilosofin
In several scientific and technical educations today we meet mathematical studies in differential- and integral calculus. The classic mechanics is a foundation for the physics and it has made it possible for today's technical developments that we in our everyday life meet and make use of. The intention for this essay is to give a picture of the person behind this discoveries that changed the science and the world. Besides the purpose to bring the reader on a journey through Isaac Newton's life the main intention is to give an understanding of the way he discovered the binomial theorem, the differential- and integral calculus, the numerical methods Newton-Raphson's and Newton's interpolation-polynomial, Newtons identities and his classification of third-degree curves and elliptic curves. A derivation of Kepler's first law is also included..
HAVECA-modellen - En metod för att fortlöpande säkra ett internt nätverk mot tredjepart
This thesis will address a problem concerning availability of information
systems at an enterprise within the financial sector and its external
suppliers, so called trusted third party. The information system resides on the
internal network of the enterprise and must be available to both employees of
the enterprise and the trusted third party simultaneously. This contradicts the
company policy which
disallows third parties access to the internal network. The HAVECA-model
introduced in this thesis provides a framework of methods, each solving a sub
problem identified in the model. The identified methods are hardening,
verification, control and assurance, together supplying a method for
continuously securing the internal network against a trusted third party.

Musiklärares inställning till IKT i sin undervisning : en studie med komparativ ansats mellan Nya Zeeland och Sverige
The aim in this thesis is to study what attitude music teachers in Sweden and New Zealand have towards Information and Communication Technology (ICT) in music education and obtain a better understanding of how their attitudes affect the way they use ICT in their teaching. Another intention is to discuss differences and similarities between the teachers´ preferences regarding this issue in the two different countries, and whether it has any effect on teaching. It's a qualitative study based on interviews with music teachers from both countries. Through the answers we can get an impression about how ICT is used in music education, how the curriculum is interpreted when it comes to use ICT in music education and how the teachers' attitudes towards ICT affect the music education. This thesis shows that teachers are positive towards ICT in music education but the attitude, knowledge and the way of using it differs, due to access to technology and different opinions about what is essential in music and what is pedagogical.
