Secondary schools have for decades debated whether they promote social reproduction which is considered to generate the homogeneous student compositions. The gap between the academic programs and vocational education programs is considered to increase. What in recent years has appeared in research is that the gap is increasing most tend to be in the specific academic program, particularly in science. This paper's intention is to describe the science program at a local level and the pupils who were admitted to the science program autumn 2009 on the basis of an educational sociological perspective. The survey consisted of a census in which all students were given the opportunity to answer a questionnaire.

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.

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.

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.

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.

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..

Finns det idag en sam- och helhetssyn avseende operativ förmåga mellan den politiska nivån ochFörsvarsmakten i Sverige? En syn där de operativa förmågorna fokuserar på att nå en gemensamönskad effekt istället för enskilda försvarsgrenar, förmågor eller i värsta fall förbands enskildautveckling? Uppsatsens syfte är att undersöka, med stöd av implementeringsteorin, spårbarhetenav Regeringens direktiv avseende operativ förmåga i Försvarsmakten. Utgångspunkten tas i Försvarsmaktensvision och de doktriner som försvarsmaktsledningen utgivit för att styra organisationenunder perioden 2001?2004, samt i intervjuer med militära representanter.Några delar som framkommer i uppsatsen är att direktiven från Regeringen återfinns i samtligatexter hos Försvarsmakten. Dock talas det inte så mycket om huvuduppgifterna under intervjuernautan mer om framtiden och hur fel det är att numera ha väpnad strid, som enda uppgift.

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.

Technology based self-service (TBSS) used in supermarket self-scanning checkouts is a relatively new phenomenon in Sweden. Studies on TBSS as a self- checkout device have been formerly carried out but with focus on the customer perspective. The authors therefore saw a challenge in covering the self-scan checkout concept, from a company perspective. The purpose of this research paper is to investigate, through a management perspective, the changes brought about by implementing an innovative TBSS system in Swedish supermarkets, and its effect on the competitiveness of the company. This is done by presenting and linking the theoretical framework and empirical study in the research.

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

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.

An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.

The management of assets in organisations today can be a challenging task and optimising their usage is critical to ensure maximum profit. For rental businesses offering tangible products efficient management of movable assets are an essential part of the business strategy. The main purpose of this study is to investigate how asset management and asset information management can be carried out in rental businesses and in what ways information technology can support it. By doing a literature review combined with a case study where three rental businesses and their use of information technology were examined we could identify several important aspects regarding asset information management. The results we have found is that rental businesses with a high degree of digitization in existing asset information management systems are able to rationalize existing work processes, which in some ways changes the roles of employees.
