This thesis has focused on digital born personal archives; how they are different from analog paper archives and possible ways to overbridge these differences. It is also studied how archivists and librarians are dealing with digital archives, what they think about new proactive solutions when collecting private papers and collections and positive and negative effects with this way to work. The thesis is delimitated to only private collections and digital created material. It do not concern digitized material or electronic documents in government or business organizations.The challenges in digital curation and administration are discussed in aspect of the Records Continuum Model. The empirical material is also put in relation to research in Personal Information Management and identity theory.

Close to the city center of Reykjavik lies the combined national- and university library of Iceland. Usually, these two types of institutions are separated. The purpose of this essay is to investigate how the library in fact selects the new digital material to offer the users in Iceland, and if the combined mission creates any problems or conflicts.The investigation examines the planning and the content of the digital library, what user groups are addressed and how the organisation is held together despite the different missions. If cultural context in Iceland makes a difference for what is selected and offered to the users is also discussed.Six informants in strategic library positions dealing with the digital national- or university library, were interviewed. The answers have been analysed in light of the library&information literature on building and maintaining digital library collections and organizational and marketing theory.The main result of the study is that the informants do not see a conflict between the missions of the organisation, although traces of a struggle were found in some areas.

Today digital guides are most frequently used by the museum and tourism industries. They are also used for education purposes. They make it possible to distribute information and have it easily accessible. In addition to written information they add sound, pictures and videos which lift the whole impression of the visited place to a higher level. A variety of systems currently in use today have been evaluated.

This thesis examines source criticism and critical thinking among upper secondary school students in social science in three different schools in Sweden. Our particular focus lies in investigating the student's critical thinking skills and evaluation of digital sources when they work independently with different projects. How do students value and sort the information they find? We looked furthermore at what factors that may influence students in their evaluation of sources. Moreover, the purpose of this thesis to investigate how the student's critical thinking skills can be used as tools to become more information literate in a learning context.

Information and communication technology (ICT) is an important part of society. Learning occurs in all contexts and many students already use various digital media in their leisure time. This article, based on a case study in a One-to-One school. It describes how teachers perceive that their teaching is influenced when their pupils get a laptop. The purpose of this study is to investigate how the focus on one-to-one influence teachers' work in the classroom.

Eskilstuna Folkhögskola is located in Munktellstaden in Eskilstuna. The school has two separate buildings with entrances that are difficult to find. By having two separate buildings, and to be in an area where there are rules and guidelines for the area's environment, makes it difficult to guide visitors to the school premises.The purpose of my research was to examine how to guide visitors to the school, and how to increase understanding that the school's various buildings are connected.Through practices such as site analysis, interviews, I found that the guidelines are not adapted to the current situation that is established in the district.Through theory and empirical material I have produced a design proposal to facilitate Wayfinding to Eskilstuna Folkhögskola. This is presented as a landmark and a clarification of the schools entrances and signage..

Allt fler skolor satsar på digitalisering och köper in egna datorer till eleverna. I samband med detta ställs det krav på eleverna att de skall kunna hantera tekniken och vara digitalt komp-etenta. Digital kompetens ses som en viktig del för elever att besitta och för att fungera i vårt samhällsliv. Detta är dock ingenting som skolan vi studerat främjar då de inte bidrar till en ökad digital kompetens hos eleverna. Det finns forskare som däremot anser att det är i skolan som eleverna bör få sin digitala kompetens.

The aim of this thesis is to make a contribution to the field of design oriented theory, regarding young children and their way to digital competence. My research question is: How can a preschool with a certain pedagogical ICT-design give the children affordances for media play and for developing a digital competence?The European Parliament points out digital literacy as one of the Key Competences for life long learning. A digital competence is built on basic ICT (Information and Communication technology) skills. Skills you can develop any time during life, weather you are young or old.

Title: Ethics in thought and practice ? a qualitative study in how editorial staff at student magazines reason about ethics. (Etik i tanke och praktik ? en kvalitativ studie i hur studenttidningsredaktioner resonerar kring etik)Number of pages: 30 (37 including enclosures)Author: Bianca GidebackTutor: Peder Hård af SegerstadCourse: Media and Communication studies CPeriod: Spring 2010University: Division of Media and Communication, Department of Information Science,Uppsala University.Purpose/Aim: The purpose of this study is to explore how students that work at student magazines reason about ethics of journalism and how they transform it into practice. By identifying what circumstances in the context of the student magazine that can affect the work this study aim to see if and how this can affect how they conform to ethics of journalism in practical situations.

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.

Ljus är så pass självklart att vi oftast inte tänker på hur viktigt det är för oss. Det finns teorier som menar att ljus har en stor betydelse för hur vi upplever saker. Därför kan ljussättning spela en viktig roll inom exempelvis film. Med hjälp av två ljussättningstekniker som används inom film har jag skapat två olika känslor inom en och samma digitala 3D-miljö, för att undersöka om det med enbart ljussättning går att påverka hur vi upplever stämningen inom en 3D-miljö. Sedan har jag intervjuat nio personer för att undersöka om detta är möjligt med enbart hjälp av belysning eller om det krävs fler moment att ta in i beräkningen.

The essay explores how the category ?religion? occurs and functions in the regulatory documents governing the Swedish public service companies. 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.

Syftet med högskoleavhandlingen var att konstruera en klass-D förstärkare för audio med en DDXi-2161 krets från Apogee. Förstärkaren har en digital stereoingång för I²S-format. Digitalisering av en analog audiosignal sker med codec-kretsen WM8731 från Wolfson. För att möjliggöra implementering av funktioner för digital signalbehandling av audiosignalen ingår en FPGA-krets från Altera i systemet. Gränssnitten mellan codec-kretsen och FPGA:n samt FPGA:n och klass-D förstärkaren är beskrivna med VHDL och implementerade i FPGA:n.

Title: ?Du är partiledare (?) men inte minst en helt vanlig människa? ? En studie av partiledarnas framträdanden i Nyfiken på partiledaren.Authors: Marcus Alakangas and Martin RidderstolpeSubject: Undergraduate research paper in journalism studies, Dept. of journalism, media and communication (JMG) Gothenburg UniversityTerm: Spring 2014Supervisor: Mats Ekström, JMG, Gothenburg UniversityPurpose: Our main purpose is to examine whether there is a pattern of similarities to which the Swedish party leaders adapt to in their narratives and presentation of self in the television show Nyfiken på partiledaren.Method: Etnographic Content AnalysisProcedure: The first part of all eight episodes was transcribed and analyzed from the perspective that the interviewee is doing a presentation of self.Results: There are tendencies that the party leaders adapt to similar patterns in their narratives and presentation of self. The main aspect of that is in the way they portrait themselves as ordinary persons that people can relate to. Another aspect is that the narratives they put forth are in coherence with their political views.
