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.

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

The purpose of this bachelor's thesis is to investigate how working librariansmanage controversial media. It builds on three debates in the media about libraries and booksthat have taken place during the years of 2012 and 2013. The questiones asked were: How dolibrarians manage racist media? How do librarians manage media that instructs on how tocommit crimes? How do librarians manage sexually explicit media? And lastly, how dolibrarians manage pressure from outside of the library? The theoretical framework consists ofRobert Hauptmans division of the two kinds of ethical strands of librarianship, in this thesiscalled ?Free information? and ?Information responsibly?. The method used to collectempirical material was qualitative interviews.

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.

The purpose of this essay is to investigate how the crisis communication was perceived between SAS, massmedia and citizens during the volcano crisis in 2010. The questions posed are: - How did the communication between SAS, media and citizens function during the crisis? - How did senders, intermediaries and beneficiaries experience the information and communication during the crisis? - How important was the internet communication for SAS, media and citizens during the crisis?The collected material consists of interviews and desktop research of material from Internet.The study shows that the communication between SAS, the media and citizens worked well on the social medias but was weaker in all other mediachannels. SAS was also weak in following up information received by media and travelers, and they therefore they had a different picture of the situation during the crisis. SAS thought that the communication worked fine between the parties involved.

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.

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

The purpose of this media scientific study is to contribute to a better understanding about how blind people?s empowerment and participation may affect their role in the digital society.Earlier international studies in this area have shown that blind people not only need more knowledge then the seeing population about the computer, but also about the technology behind their tools for using Internet. The results from these studies have also shown that Internet increases the blind people?s independents and that those who use Internet feel more involved in the society.A qualitative method was chosen to study the three most common categories from the earlier studies: knowledge of technology, empowerment and participation. Are there differences in the results compared to our study in Sweden 2014?Interviews with eight blind, experienced computer users have shown that knowledge of technology is essential for their use of Internet and that the Internet increases their empowerment and their participation.

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

ABSTRACTSegregation is more and more common in the Swedish society, especially in those suburbs called ?miljonprogramsförorter? which are characterized as grey and boring districts with low status. These suburbs are often mentioned in the media and the public associate them with immigrants, problems and crimes. Kungsmarken in Karlskrona is one of these suburbs and the purpose of this essay was to compare the media image with the images local participants had of Kungsmarken. The questions I brought up were how media was describing Kungsmarken, how this image has contributed to the low status of Kungsmarken, and if this image was reflecting the local participants? images.

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.

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.
