    Sociala medier för att hantera kundkontakter2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    KONTEXT. I takt med att Internets framväxt och fler och fler människor ansluter sig till sociala medieplattformar som Facebook, uppkommer nya sätt att interagera och kommunicera mellan varandra. Samtidigt ökar antalet organisationer och företag, som i sin tur måste hitta nya vägar för att deras marknadsföring ska sticka ut och bli uppfattad. För att nå ut till målgruppen med budskap, måste organisationen vara där målgruppen är. Därför har Facebook blivit en ny del av företags marknadsföringsredskap. Denna studie är fokuserad på Malmö stadsbiblioteks användning av Facebook som ett kommunikationsverktyg i hanteringen av kundkontakter. MÅL. Syftet med denna magisteruppsats är att undersöka Malmö stadsbiblioteks användning av Facebook, med ett huvudsakligt fokus på undperception och kundens upplevelse av kommunikationen, för att utreda hur Malmö stadsbibliotek bör använda Facebook i marknadsföringssyfte. METOD. Denna studie är baserad på en empirisk undersökning innehållandes en innehållsanalys av Malmö stadsbiblioteks Facebooksida, och också en onlineenkät gjord på de som ”gillar” och följer Facebooksidan. RESULTAT. Resultatet av den empiriska studien visar att Malmö stadsbibliotek står inför en bred målgrupp där segmentering är nödvändigt för att skapa och sprida rätt budskap till den primära målgruppen. Malmö stadsbibliotek publicerar statusuppdateringar relativt jämnt fördelat på månadens dagar och det är möjligt att peka ut olika kategorier av uppdateringar med olika målgruppsresponser och upplevelser från följarna. Resultatet av studien presenteras som diagram och tabeller med beskrivningar för att förbättra illustrationen och därför öka förståelsen. SLUTSATS. Slutsatsen av denna magisteruppsats är att de flesta respondenterna är positiva inför Malmö stadsbiblioteks användning av Facebook. Baserat på diverse befintliga teorier är marknadsföring på sociala nätverk ett bra sätt att interagera, kommunicera och få feedback från kunder för att kunna bygga goda relationer med kunderna. Detta är någonting som är väldigt viktigt i nuläget när antalet företag och reklambruset är så högt som det är. Det finns ingen enkel väg till framgång, med enbart en korrekt väg. Det är beroende av varje specifik organisation och deras specifika primärmålgrupp.

    Kommunal verksamhetsprocess efter införandet av en e-tjänst: Informationsflöde och informationshantering sett ur ett Lean-perspektiv2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Trots de svenska medborgarnas ökande krav på digital självservice via e-tjänster, går införande trögt hos kommunerna. En anledning är den relativt låga kunskap som finns i området. Främst vad gäller avancerade e-tjänster som förutom att öka medborgarnas tillgänglighet, insyn och delaktighet i sina offentliga ärenden, även ska minska den administrativa hanteringen för att istället låta mer av resurserna gå till kärnverksamheten. I den här kvalitativa fallstudien studerades hur en kommunal verksamhetsprocess utvecklas vid införandet av en e-tjänst. Hur slöseri kan identifieras i processen informationshantering och informationsflöde och hur dessa förändrats efter att e-tjänsten införts. Resultatet baserades på material från intervjuer och analyserades utifrån Leans kategorier av slöseri och teorin om Microsystem. Resultatet visade att slöseri som uppstår i informationshantering och informationsflöde mellan enheter eller microsystem kunde identifieras om alla microsystem kartlägger processen tillsammans. Mycket slöseri hade tagits bort i utvecklingsarbetet och lett till en smidigare och troligtvis mer effektiv process. Ett antagande men som även bekräftades av personalens upplevelser från testförsöken. Processutvecklingen tillsammans med e-tjänsten har säkerställt delar av processflödet där antalet informationsöverföringar blivit färre och på så sätt troligtvis även minskat risken för att missförstånd och felhantering ska uppstå av informationshanteringen.

    Information and Communication Technologies in Support of Remembering: A Postphenomenological Study2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to study the everyday use of ICT-enabled memory aids in order to understand and to describe the technological mediations that are brought by them (i.e. how they shape/mediate experiences and actions of their users). To do this, a post-phenomenological approach was appropriated. Postphenomenology is a modified, hybrid phenomenology that tries to overcome the limitations of phenomenology. As for theoretical framework, ‘Technological Mediation’ was adopted to conduct the study. Technological Mediation as a theory provides concepts suitable for explorations of the phenomenon of human-technology relation.

    It was believed that this specific choice of approach and theoretical framework would provide a new way of exploring the use of concrete technologies in everyday life of human beings and the implications that this use might have on humans’ lives. The study was conducted in the city of Växjö, Sweden. Data was collected by conducting twelve face-to-face semi-structured interviews. Collected data was, then, analyzed by applying the concepts within the theoretical framework – Technological Mediation - to them.

    The results of this study provided a list of ICT-enabled devices and services that participants were using in their everyday life in order to support their memory such as: calendars, alarms, notes, bookmarks, etc. Furthermore, this study resulted in a detailed description of how these devices and services shaped/mediated the experiences and the actions of their users.

    Att fånga en oskuld: En undersökning kring ungdomars intresse för ekonomisk information online2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att vid 18 års ålder tvingas ansvara för sina handlingar är för många ett stort steg, inte minst då en del av ansvaret är ekonomi. Ungdomarna vänder sig ofta till föräldrarna med frågor, men var ska de vända sig när föräldrarna inte har svaret? Bankerna har börjat söka sig lägre ner i åldrarna med sin marknadsföring för att fånga kunden innan denne blir myndig, men fortfarande är det många frågetecken kring informationen ungdomarna behöver.

    Uppdraget var att undersöka vad ungdomar behöver för information i en webbplats riktad mot ungdomar från banken. En undersökning genomfördes med en enkätundersökning med 100respondenter och tre olika fokusgrupper som genererade att ungdomarna känner att banker är alldeles för avlägsna. En minskad distans skulle medföra att ungdomarna lättare vänder sig till banken vid frågor kring sin ekonomi vilket i sin tur medför att deras intresse kring privatekonomiska frågor ökar.

    Designförslaget som presenteras fokuserar mycket på en funktion med textbaserad personlig service med co-browsingfunktioner som tillåter en bankman guida den unga kunden genom webbplatsen. Strävan är att ungdomarna ska känna en samhörighet till banken och lättare kan få alla typer av frågor besvarade då de var osäkra på vilken information de behöver. Om man inför en sådan tjänst bör användbarhetstest och utvärderingar på designförslaget genomföras för att kontrollera om distansen mellan bank och ungdom minskar.

    How does the alignment of IT to business strategy affect the organisation of the IT function?2008Student thesis
    Abstract [en]

    Date: 2008-06-04

    Purpose: The primary goal of this research is to describe the IT function and examine how its alignment to an organisations strategy affects the way it is organised.

    Method: The chosen method was a purely theoretical examination with the use of the case study of Windham International as primary resource and secondary resources such as book and literature review used for the thesis.

    Research Questions: How does the alignment of IT to business strategy affect the organisation of the IT function?

    Conclusion: One of the findings was that a few researchers seem to suggest that the centralized mode of organising IT was symbolic of the past, while outsourcing and decentralization are the modern approach to organising IT. Wyndham International shows the opposite, after the introduction of the CIO in 2002, centralization was the chosen mode of organisation because that was what would best fit the new strategic approach of the organisation. Insourcing rather than outsourcing proved to be a winning formula.

    IT-supported Knowledge Repositories: Increasing their Usefulness by Supporting Knowledge Capture2008Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Organizations use various resources to achieve business objectives, and for financial gain. In modern business, knowledge is a critical resource, and organizations cannot afford not to manage it. Knowledge Management (KM) aims to support learning and to create value for the organization. Based on three levels of inquiry (why, what, how), work presented in this thesis includes a synthesized view of the existing body of knowledge concerning KM and hence a holistic characterization of KM. This characterization reveals a strong dependency between KM and Learning Organization (LO). Neither of them can be successful without the other. We show that a KM project resulting in an IT-supported knowledge repository is a suitable way to start when the intention is to initiate KM work. Thus, our research focuses on ITsupported knowledge repositories.

    Large numbers of KM projects fail, and organizations lack support for their KM undertakings. These are the main problems that our research addresses. In order for an IT-supported knowledge repository to be successful, it must be used. Thus, the content of the repository is critical for success. Our work reveals that the process of capturing new knowledge is critical if the knowledge repository is to include relevant and updated knowledge. With the purpose of supporting the capture process, this thesis provides a detailed characterization of the capture process as well as guidance aiming to facilitate the implementation of the capture process in such a way that knowledge is continuously captured, also after the KM implementation project is completed. We argue that the continuous capture of new knowledge which can potentially be stored in the knowledge repository will, in the long term perspective, have a positive influence on the usefulness of the repository. This will most likely increase the number of users of the repository and accordingly increase the number of successful KM projects.

    All the work presented in this thesis is the result of a qualitative research process comprising a literature review and an empirical study that were carried out in parallel. The empirical study is a case study inspired by action research, which involved participation in the project Efficient Knowledge Management and Learning in Knowledge Intensive Organizations (EKLär).

    Planning for Information Systems Development: A Framework for supporting the management of Success Factors2002Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    In the information systems development process there are important success factors. By doing an extensive literature survey we have found that these factors emerge mainly from organisational issues concerning the objective of the process and the stakeholders.One factor - to discuss the system, its subsystems and to define the system's boundary - is a prerequisite for all the others. Factors emerging from the objective are mainly about the objective being well analysed and defined, being accepted among the stakeholders and meeting business objectives. Factors emerging from stakeholders are mainly about involving the right stakeholders in the process, achieving a positive attitude and taking care of their needs about knowledge and confidence. Based on this we have developed a framework aiming to guide organisations in what considerations they should make before the project begins. As a result of our framework there will be both a clear objective, which support the business mission, as well as positive stakeholders to support the information systems development process.

    Vidareutveckling av informationssystem: Vilka olika aktiviteter går att identifiera i VAD-fasen?2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Utmärkande för morgondagens IS är att integrera befintliga resurser med nya IS (Lindencrona 2000), dvs att vidareutveckla i stället för att nyutveckla. Då det saknas systematiserad kunskap om den utvecklingsprocess som äger rum då morgondagens IS ska utvecklas är det av yttersta vikt att arbeten vars syfte är att belysa denna process genomförs. Syftet med denna rapport är att undersöka vilka olika aktiviteter som går att identifiera i VAD-fasen, processen fram till kravspecifikationen, då ett administrativt informationssystem ska vidareutvecklas. Inom ramen för detta examensarbete har en litteratur-survey, fokuserad på att samla in material som detaljerat belyser VAD-fasen, utförts. För att samla in material som möjliggör en identifiering av olika aktiviteter i VAD-fasen då ett IS ska vidareutvecklas, har en enkät- respektive en intervju-undersökning av olika organisationer inom aktuell population genomförts.

    Då det insamlade materialet analyserats har i VAD-fasen följande fyra olika aktiviteter kunnat identifieras då ett IS ska vidareutvecklas:

    · Fatta beslut

    · Utföra undersökningar med hjälp av informationsinsamlande aktiviteter

    · Författa dokument

    · Deltaga i diskussioner

    Det erhållna resultatet innebär en god plattform att utgå ifrån då ytterligare forskning ska göras inom området och då metoder för utvecklingen av morgondagens IS ska utvecklas och arbetas fram.

    How to Successfully Apply Critical Success Factors in Healthcare Information Systems Development?: A Story from the Field2012In: Proceedings of the 20th European Conference on Information Systems, Barcelona, Spain 2012, Association for Information Systems, 2012, p. Paper 220-Conference paper (Refereed)
    Abstract [en]

    Many studies have focused on retrospectively identifying critical success factors (CSFs) for healthcare information system (HIS) development projects. In this paper the central question is how in advance selected CSFs can be applied in the best way. An action research study has been carried out in a large Swedish healthcare organization during 2010 and 2011 where the application of four CSFs has been planned, documented and reflected upon. Challenges are identified that may arise when tailoring general CSFs to situational circumstances. For example, the self-evident CSF of ?having a clear and accepted objective? becomes tricky and complex in practice when facing 15 autonomous boards that all need to support the project. Similar insights are gained for other CSFs. More research is needed to illuminate the complexities of how to apply CSFs. Another important observation is that different CSFs strengthen one another, which implies that they should be applied and analysed in concert rather than isolated. Finally, healthcare practitioners need to be aware that CSFs are very helpful, but that tailoring general CSFs to the unique situation of the HIS development project requires much effort and continuous reflection from a holistic perspective embedded in systems thinking.

    Finding Potential Problems in the Thesis Process in Higher Education: Analysis of e-mails to develop a support system2015In: Education and Information Technologies: Official Journal of the IFIP technical committee on Education, ISSN 1360-2357, E-ISSN 1573-7608, Vol. 20, no 1, p. 21-36Article in journal (Refereed)
    Abstract [en]

    Autonomous learning hype has created much speculation in educational systems regarding how to develop the learning process. Final project (thesis) in Bachelor’s and Master’s levels is a significant part of study for students in higher education. However, there are some problems, which lead students not managing to do or finish their thesis. As a part of a solution to these problems, the Department of Computer and Systems Sciences (DSV) at Stockholm University, Sweden, has established an information and communication platform, called SciPro. The system was initiated in 2011 to support students and supervisors during the thesis process courses. This study contributes by exploring problems that learners have faced during the final project courses and analyzing discussed issues in the emails, sent to the SciPro support group, ThesisSupport. A random sample of one hundred emails has been analyzed with the help of a content analysis tool, in order to develop the categories, which cover the discussed issues. The result of the study shows six exhaustive and mutually exclusive categories of problems: 1) Thesis initiation (26 %), 2) Info-mail (4.7 %), 3) Technical issues (17.1 %), 4) Exemption (18.7 %), 5) Supervision (17.1 %), 6) Final seminar (16.4 %). Consequently, based on the significance of the categories, two groups of strategic suggestions are developed: 1) developing communications and 2) developing instructions. These strategies intend to enhance support for the autonomous learning process for the thesis courses in higher education.

    Learners’ Perceptions on the Structure and Usefulness of e-Resources for the Thesis Courses2014In: European Journal of Open and Distance Learning, ISSN 1027-5207, E-ISSN 1027-5207, Vol. 17, no 1, p. 154-171Article in journal (Refereed)
    Abstract [en]

    Nowadays, utility of information and communication technology (ICT) in education is a way to facilitate interaction and accessing information for learning in higher education. However, finding a set of structured e-resources to facilitate learning within specific courses is still a big challenge in most of the institutions and universities. This includes the problems and challenges for the thesis courses in both undergraduate (Bachelor) and graduate (Master) level in Sweden. To overcome or reduce the problems and enhance quality of outcomes in the thesis courses, the department of Computer and Systems Sciences (DSV) at Stockholm University has developed a Learning Support System, SciPro (Scientific Process), to support thesis process. This study aims at investigating learners’ perspectives on usefulness of structured e-resources in order to reduce challenges for finding information related to the thesis steps in SciPro. This is done based on an open online survey, carried out in 2012-2013 of students’ perspectives at DSV. The study found the actual problems and hence suggested a model as a way forward to sort the useful e-resources to support reducing the problems in the thesis process.

    Interaction Gaps in PhD Education and ICT as a Way Forward: Results from a Study in Sweden2016In: The International Review of Research in Open and Distributed Learning, ISSN 1492-3831, Vol. 17, no 3, p. 360-383Article in journal (Refereed)
    Abstract [en]

    Many research studies have highlighted the low completion rate and slow progress in PhD education. Universities strive to improve throughput and quality in their PhD education programs. In this study, the perceived problems of PhD education are investigated from PhD students' points of view, and how an Information and Communication Technology Support System (ICTSS) may alleviate these problems. Data were collected through an online open questionnaire sent to the PhD students at the Department of (the institution's name has been removed during the double-blind review) with a 59% response rate. The results revealed a number of problems in the PhD education and highlighted how online technology can support PhD education and facilitate interaction and communication, affect the PhD students' satisfaction, and have positive impacts on PhD students' stress. A system was prototyped, in order to facilitate different types of online interaction through accessing a set of online and structured resources and specific communication channels. Although the number of informants was not large, the result of the study provided some rudimentary ideas that refer to interaction problems and how an online ICTSS may facilitate PhD education by providing distance and collaborative learning, and PhD students' self-managed communication.

    Communication and Collaboration Gaps among PhD Students and ICT as a Way Forward: Results from a Study in Sweden2015Conference paper (Refereed)
    Abstract [en]

    The low completion rate and slow progress in PhD education have been highlighted in many studies. However, the interaction problems and communication gaps that PhD students encounter make this attempt even more challenging. The aim of this study is to investigate the peer interaction problems and ICT based solutions from PhD students’ perspectives. The data collection method was an online questionnaire and in-depth interviews were used to follow up. The target group for the survey was the PhD students in Computer Science at Stockholm University. The total number of respondents for the survey was 53 PhD students and eleven randomly selected PhD students for the interviews. The results reflected a lack of peer interaction as an important issue in the perspective of the students. Based on this, the study showed several ICT solutions that have the potential to reduce the interaction problems and thereby improve PhD students’ collaborative learning and research quality.

    Students’ Perspectives on Utility of Mobile Applications in Higher Education2013In: Trends in Mobile Web Information Systems: Revised Selected Papers / [ed] Maristella Matera, Gustavo Rossi, Springer Publishing Company, 2013, p. 44-56Conference paper (Refereed)
    Abstract [en]

    Use of Information and Communication Technologies (ICT) in pedagogy and learning in higher education supports the concept of Technology Enhanced Learning (TEL). Mobile devices and applications with educational purposes are part of using online ICT and facilitate autonomous learning in education. Using mobile applications for education has significantly improved in the last few years. However, there is still a gap, in which this concept is still not widely known and frequently experienced by learners. As a part of supporting TEL in higher education and filling this gap, the department of Computer and System Sciences at Stockholm University in Sweden is planning to develop a mobile application for the SciPro system. SciPro is the computer-mediated communication platform to support enhancement of thesis quality and facilitate autonomous learning in higher education, at both Bachelor and Master levels. This study aims to investigate and evaluate learners’ perspectives about utility of mobile applications in higher education and specifically to support SciPro functionalities. Almost 95% of the respondents use mobile applications for higher education and believe in the utility of mobile applications for supporting learning in higher education. This is while there are a few respondents (less than 5%), who do not fully share this opinion. More than 70% of the respondents think that a SciPro mobile application will add value to their thesis process. Even though it may not directly affect the speed and quality of the thesis, it will increase mobility, availability, and flexibility of accessing information and resources in SciPro.

    ICTs use in the public Greek Primary Schools: the teachers' experiences2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Education is a sector that has the potential to become a critical area of action for the full exploitation of ICT. Educational systems of developed and developing countries have an ever-increasing tendency to apply ICT to education, in an attempt to prepare their students for the future's society. This thesis attempted to explore what kind of ICT is used in the Greek Primary Schools and develop an understanding on the relationship between the ICT and the teachers. The philosophical background is post-phenomenology and the methods chosen for collecting data for this research are policy document analysis and interviews. The empirical findings show that various ICT are being used in the classrooms of the Greek Primary Schools,  others widely and others occasionally. The research compares the legal framework revolving around ICT in Primary Schools in Greece, with the teachers' own experiences and shows that the guidelines suggested by the Greek Ministry of Education cannot be followed easily, due to economical and pedagogical reasons. It also investigates the ICT's effects on the teachers and the students through the teachers' own words and perceptions. The effects are mostly positive, there are mentioned however, some negative ones to take into consideration. Finally, the research presents a number of sectors where the participant teachers suggested there is room for improvement. By comparing the legal framework with the situation in the Primary Schools, this research adds a new perspective to the previous literature. The findings show that the current situation can be improved and the teachers' statements may trigger further research.

Students, Lecturers, departments and additional questions from the shared leadership team are engaging in defining the services offered, in particular from the university library and its associated sub-services. It is an exciting time for the University as it seeks to not only define its services but also how these can be created and consumed.There are many aspects to this re-organisation and many items to be addressed. In this report,we look at the current situation at the University, as well as taking into account the aspirations of the stakeholders. We start by drawing out a Rich Picture, part of Soft System Methodology (SSM) (Checkland, 1981) which we use in order to spot opportunities that are available for further exploration. Much of the information that we use comes from material supplied by the University itself as well as interviews with the Head of Library services and Head of Library IT. We look indepth at how SSM assists in this process of evaluation through its focus on participation and how it may assist us to understand the many different perspectives collected in our research. SSM consequently assists in defining problems with solutions to any areas that have drawn our attention. Following the evaluation of collected data, discussions and our own observations, we identify that a digital wall that is being proposed for the redesigned library presents an opportunity to explore possibilities for exploitation of this technology. Further research on other digital walls such as Brisbane’s Cube (Abdi et al, 2014), and Auraria Library’s Discovery Wall(Burch, 2016) shows some of the uses that these walls have been put to and how the Institutions use them. We then use a number of models to evaluate the data that we collected on digital walls and from the North American University and analyse it in order to inform our thinking. These models can be used independently or collectively to evaluate data from different perspectives. As such we were able to look at problems and solutions from the perspective of many of the actors involved in shaping the future library services. These models and results are discussed in the report. Finally, we take our results and make a number of proposals for the North American University digital wall along with the relevant justifications at the end of this report.

    Kreditbedömningar och Data Warehouse: En studie om riktlinjer för insamling, transformering och inladdning av kreditbedömningsinformation i Data Warehouse2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien har handlat om att ta fram riktlinjer för hur extrahering, transformering och inladdning (ETL) av kreditbedömningsinformation bör göras när det kommer till att införa ett Data Warehouse (DW). Ett kvalitativt angreppssätt har använts med både en fallstudie och en intervjustudie, där fallstudien genomfördes med Asitis AB som är en systemleverantör förfinans- och reskontrafinansiering (factoring) för att undersöka potentiella affärsmöjligheter med ett DW med kreditbedömningsinformation. Intervjustudien användes för att samla in värdefull information från individer inom alla berörda problemområden, och användes sedan i fallstudien. Resultatet var både framgångsfaktorer och fallgropar för ETL-processen med kreditbedömningsinformation som kan fungera som stöd för organisationer med detta behov. Det har visat sig att ETL-processen för kreditbedömningsinformation utgör ett område med stor potential för affärsmöjligheter, där det krävs hög kompetens, domänkunskap, proaktivitet och juridisk kunskap vid genomförande av ETL-processen.

    Datakvalitetsverktyg i datalager: Hur hanterar datakvalitetsverktyg datakvalitetsfaktorer?2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    I ett företag finns data utspridd i olika datasystem. För att lättare och snabbare komma åt data bör data finnas samlad på ett ställe d.v.s. ett datalager. Om datalagret ska fungera som ett beslutsstöd för företagsledningen är det viktigt att data håller en hög datakvalitetsnivå så att beslut fattas som gynnar företaget. För att kontrollera datakvalitet kan datakvalitetsverktyg användas. Dessa innehåller funktioner för att lösa olika datakvalitetsproblem. I rapporten behandlas hur datakvalitetsfaktorerna korrekthet, datatypsenlighet, konsistens, lämplighet, integration, kompletthet och inga dubbletter hanteras av datakvalitetsverktyg för datalager. En litteraturstudie har genomförts för att se hur datakvalitetsfaktorerna hanteras samt om behandlingen varierar mellan olika datakvalitetslösningar. Litteraturstudien har också använts för att upptäcka om olikheter och likheter i behandlingen av enskilda datakvalitetsfaktorer har påverkat hur väl faktorerna hanteras i lösningarna. Samtliga lösningar i arbetet innehåller datakvalitetsverktyg som beaktar de utvalda datakvalitetsfaktorerna men använder ibland olika tillvägagångssätt. Skillnader finns i hur väl de olika lösningarna hanterar enskilda datakvalitetsfaktorer

    Användandet av web services inom 24–timmarsmyndigheten2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Regeringen har en vision att en given fråga skall besvaras med ett samlat svar från flera myndigheter. För att lyckas med detta måste myndigheterna samarbeta i en större utsträckning än vad som sker i dag. Speciellt viktigt är det att information kan utbytas mellan myndigheterna på ett effektivt sätt. För att lyckas med detta så har statskontoret gått ut med att web services är en teknik som kan användas. Om tekniken skall kunna användas ut fullt krävs att det finns ett gemensamt register.

    I det här arbetet används enkäter för att undersöka i vilken utsträckning web services användes inom myndigheterna i dag, samt för att undersöka myndigheternas inställning till tekniken. Det visade sig att det fins en positiv inställning till web services. Dock finns det inget gemensamt register, vilket är oroande då det kan bidra till att dra ner tjänsteutbytet mellan myndigheterna.

    Sakernas Internet: En studie om vehicular fog computing påverkan i trafiken2018Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Future vehicles will be very different from today's vehicles. Much of the change will be done using the IoT. The world will be very connected, sensors will be able to access data that most of us did not even know existed. More data also means more problems. Enormous amounts of data will be generated and distributed by the future's IoT devices, and this data needs to be analyzed and stored efficiently using Big data Principles. Fog computing is a development of Cloud technology that is suggested as a solution to many of the problems IoT suffer from. Are traditional storage and analysis tools sufficient for the huge volume of data that will be produced or are new technologies needed to support development?

    This study will try to answer the question: "What problems and opportunities does the development of Fog computing in passenger cars have for consumers?" The question is answered by a systematic literature study. The objective of the systematic literature study is to identify and interpret previous literature and research. Analysis of the material has been done by using open coding where coding has been used to sort and categorize data. Results show that technologies like IoT, Big data and Fog computing are very integrated in each other. In the future vehicles there will be a lot of IoT devices that produce huge amounts of data. Fog computing will be an effective solution for managing the amount of data from IoT devices with a low latency. The possibilities will create new applications and systems that help improve traffic safety, the environment and information about the car's state and condition. There are several risks and problems that need to be resolved before a full-scale version can be used, such as data authentication, user integrity, and deciding on the most efficient mobility model.

    Affärsrelationer vid elektronisk handel2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Detta examensarbete behandlar elektronisk handel mellan företag och vilken affärsrelation som företaget har med sina företagskunder efter införandet av elektorisk handel. Telefonintervjuer har skett med fyra olika företag som ingår i möbelbranschen. Syftet med arbete är att se om företagens förväntningar med avsikt på fem olika aspekter som utgör en god affärsrelation infriats.

    Denna undersökning visar att aspekterna samarbete och förtroende är de två aspekter som företagen har störst förväntningar på. De andra tre aspekterna engagemang, anpassning och kunskap om kunden har generellt företaget inga större förväntningar innan införandet av elektronisk handel. Om dessa förväntningar har infriats eller inte besvaras inte i denna undersökning på grund av olika faktorer som har spelat in.

    Abstract [en]

    The communication of the intangible benefits to different stakeholders is important at the development for organizational resource and could be described as a boundary-spanning activity. In this study we build on Ahlin’s model (2014) and illustrates categorization of intangible benefits of digital information by using Carlile’s (2002; 2004) efficient boundary objects, the syntactic, semantic and pragmatic. Qualitative empirical pictures from three cases are illustrated by questions, derived from the efficient boundary objects. The illustrations show that this is an accessible path forward and that the illustrations can be changed to further research with the goal for practical test the communication model.The communication of the intangible benefits to different stakeholders is important at the development for organizational resource and could be described as a boundary-spanning activity.

    A semiotic perspective on semantics interoperability2012Conference paper (Refereed)
    Abstract [en]

    While information technology enables us to access more material than ever before, we need to come to grips with the disagreeable fact that data is not information. Sharing data without safeguarding comprehension may lead to confusion at best and disaster at worst. The issue at hand is one of ensuring semantic interoperability between actors from disparate contexts. Research into this problem is plentiful, but typically focused around specific subject matters, limiting its appeal to a limited range of scholars and practitioners. Based upon a literary study, we identify two extreme approaches to managing semantic interoperability. These are denoted top-down and bottom-up. We illustrate real world instances of these approaches using the TFI-model based on a case study encompassing two organizations. Our theoretical model is found to be a viable lens through which to generalize and interpret issues pertaining to semantic interoperability between human actors. We therefore see a need for further research into human-based on semantic interoperability.

    Ett holistiskt Business Intelligence för användning i Verksamhetsutveckling2015Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Världen förändras. Alla kan kommunicera med alla och kunskap är lättillgänglig. Idag kan vi skicka data mellan varandra med mobiltelefoner utan några direkta geografiska begränsningar och med hastigheter i nivå med vad en vanlig dator gjorde internt mellan processorn och internminnet 1984. Informations- och kommunikations-teknologin har skapat nya förutsättningar för företag att göra affärer samtidigt som den behövs för överlevnad med dagens snabba samhälleliga förändringar.

    Personalen beskrivs ofta som företagets viktigaste tillgång. Verksamhetens prestation beror mycket på deras engagemang och möjligheter att utföra sina arbetsuppgifter. Samtidigt är det även de som kan sina egna arbetsuppgifter bäst och har mycket kunskap kring hur de kan förbättras. Däremot är det inte så lätt att få fram dessa kunskaper, och som en f.d. koncernchef för Siemens sagt om problematiken: ”Om Siemens visste allt det som Siemens vet skulle vi inte ha några problem”.

    Den här studien ska utreda hur mobila teknologier kan användas för att ta till vara på personalens inneboende kunskaper på ett systematiskt sätt för att användas med Business Intelligence. Detta för att skapa möjligheter till anpassningsbara och lärande organisationer samt ge förutsättningar för innovativa organisationsstrukturer och affärsmodeller.

    De slutsatser som dras är att om bara företaget förstår relevansen i att anpassa sig, värdet i personalens inneboende kunskaper samt att de är beredda att ta initiativet, finns det stora möjligheter till att skaffa sig insikter kring sin egen verksamhet vilka kan användas för ständiga förbättringar.

    Kartläggning av faktorer som påverkar acceptansen vid införande av telemedicin i ett utvecklingsland: IT som stöd för att bedriva vård över stora avstånd2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Allt fler organisationer väljer att förbättra sin verksamhet med hjälp av ett informationssystem. Användningen av datoriserade informationssystem ökar inom hälso- och sjukvården och sjuksköterskorna blir alltmer beroende av IT. Idag utgör telemedicinska tillämpningar en delmängd av alla de IT-tillämpningar som finns inom hälso- och sjukvården. Införandet av telemedicin bär med sig stora problem och hinder och ett av de mest kritiska problemen som bör försöka undvikas är utebliven användaracceptans. Då tidigare undersökningar inom telemedicin främst har genomförts i industriländer syftar detta arbete till att undersöka vilka faktorer som kan påverka acceptansen vid införande av telemedicin i utvecklingsländer. Genom att intervjua och observera sjuksköterskor och en systemutvecklare verksamma i ett telemedicinprojekt i Indien erhölls faktorer som har både en positivt och negativ inverkan på användaracceptansen vid införande av telemedicin. Faktorerna som framkom i resultatet var information och utbildning, upplevelsen av ny teknik, tidigare erfarenheter av datorer, inledande svårigheter vid användning av systemet, förståelsen för nyttan med systemet, användarmedverkan, användbarhet, begränsningar vid arbete med systemet, arbetsbelastning, mentala hinder, rädsla för att mista den yrkesverksamma friheten, förändringsovilja, fast i en gammal föreställning och teknikhinder.

    Encryption in Delocalized Access Systems2008Independent thesis Basic level (professional degree), 20 points / 30 hpStudent thesis
    Abstract [en]

    The recent increase in performance of embedded processors has enabled the use of computationally heavy asymmetric cryptography in small and power efficient embedded systems. The goal of this thesis is to analyze whether it is possible to use this type of cryptography to enhance the security in access systems.

    This report contains a literature study of the complications related to access systems and their functionality. Also a basic introduction to cryptography is included.

    Several cryptographic algorithms were implemented using the public library LibTomCrypt and benchmarked on an ARM7-processor platform. The asymmetric coding schemes were ECC and RSA. The tested symmetric algorithms included AES, 3DES and Twofish among others. The benchmark considered both codesize and speed of the algorithms.

    The two asymmetric algorithms, ECC and RSA, are possible to be used in an ARM7 based access system. Although, both technologies can be configured to finish the calculations within a reasonable time-frame of 10 Sec, ECC archives a higher security level for the same execution time. Therefore, an implementation of ECC would be preferable since it is faster and requires less resources. Some further suggestions of improvements to the implementation is discussed in the final chapters.

    Using text prediction for facilitating input and improving readability of clinical text2013In: MedInfo 2013: Proceedings of the 14th World Congress on Medical and Health Informatics / [ed] Christoph Ulrich Lehmann, Elske Ammenwerth, Christian Nøhr, IOS Press, 2013, p. 1149-1149Conference paper (Refereed)
    Abstract [en]

    Text prediction has the potential for facilitating and speeding up the documentation work within health care, making it possible for health personnel to allocate less time to documentation and more time to patient care. It also offers a way to produce clinical text with fewer misspellings and abbreviations, increasing readability. We have explored how text prediction can be used for input of clinical text, and how the specific challenges of text prediction in this domain can be addressed. A text prediction prototype was constructed using data from a medical journal and from medical terminologies. This prototype achieved keystroke savings of 26% when evaluated on texts mimicking authentic clinical text. The results are encouraging, indicating that there are feasible methods for text prediction in the clinical domain.

    Medical vocabulary mining using distributional semantics on Japanese patient blogs2014In: Proceedings of the 6th International Symposium on Semantic Mining in Biomedicine, 2014, p. 57-62Conference paper (Refereed)
    Abstract [en]

    Random indexing has previously been successfully used for medical vocabulary expansion for Germanic languages. In this study, we used this approach to ex- tract medical terms from a Japanese pa- tient blog corpus. The corpus was seg- mented into semantic units by a semantic role labeller, and different pre-processing and parameter settings were then evalu- ated. The evaluation showed that simi- lar settings are suitable for Japanese as for previously explored Germanic languages, and that distributional semantics is equally useful for semi-automatic expansion of Japanese medical vocabularies as for med- ical vocabularies in Germanic languages.

    Switched Multi-hop Priority Queued Networks-Influence of priority levels on Soft Real-time Performance2010Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    In the last few years, the number of real-time applications has increased. These applications are sensitive and require the methods to utilize existing network capacity efficiently to meet performance requirements and achieve the maximum throughput to overcome delay, jitter and packet loss. In such cases, when the network needs to support highly interactive traffic like packet-switched voice, the network congestion is an issue that can lead to various problems. If the level of congestion is high enough, the users may not be able to complete their calls and have existing calls dropped or may experience a variety of delays that make it difficult to participate smooth conversation.

    In this paper, we investigate the effect of priority levels on soft real-time performance. We use the priority queues to help us manage the congestion, handle the interactive traffic and improve the over all performance of the system. We consider switched multi-hop network with priority queues. All the switches and end-nodes control the real-time traffic with “Earlier Deadline First” scheduling. The performance of the network is characterized in terms of the average delay, the deadline missing ratio and the throughput.

    We will analyze these parameters with both the bursty traffic and evenly distributed traffic. We will analyze different priority levels and will see how the increase in priority level increases the performance of the soft real-time system.

    Dynamiska metoder för små systemutvecklingsprojekt2003Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Litteratur inom systemutvecklingsområdet visar behov av nya snabbare systemutvecklingsmetoder. Orsaken är komplexiteten både i systemutvecklingsprojekten och i organisationer, där systemutveckling sker. Nu föredras små projekt, som omfattar färre än tio deltagare och genomförs på mindre än ett år. De traditionella systemutvecklingsmetoder anses vara lämpliga för stora projekt. Det finns nya systemutvecklingsmetoder, som får benämningen dynamiska metoder, för små projekt. I detta examensarbete studeras faktorer för två dynamiska metoder som gör dem lämpliga för små projekt. De två dynamiska metoderna som kommer att studeras är Extreme Programming och en specifik dokumenterad anpassning av RUP.

    Syftet med detta examensarbete är att studera metoddokumentationen för två dynamiska metoder för att reda ut i vilken utsträckning de passar för små projekt. Ett ytterligare syfte är att genom analys av andras erfarenheter om tillämpningar av de två metoderna redogöra för det som styrker argumenten om deras lämplighet för små projekt.

    För att besvara frågeställningen studerades litteratur och ett antal artiklar. Två telefonintervjuer genomfördes också för att besvara en av de två delfrågorna, som tillsammans utgör frågeställningen för denna studie. Resultatet visar att den specifikt dokumenterade anpassade RUP inte följer alla aspekter för små projekt. Däremot följer Extreme Programming alla de aspekterna.

    What Are You Doing And Feeling Right Now?2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Understanding and capturing game play experiences of players have been of great interest for some time, both in academia and industry. Methods used for eliciting game play experiences have involved the use of observations, biometric data and post-game techniques such as surveys and interviews. This is true for games that are played in fixed settings, such as computer or video games. Pervasive games however, provide a greater challenge for evaluation, as they are games that typically engage players in outdoor environments, which might mean constant movement and a great deal of the players' motor skills engaged for several hours or days. In this project I explored a new method for eliciting different aspects of the game play experience of pervasive game players, specifically focusing on motional states and different qualities of immersion. I have centered this work on self-reporting as a means for reporting these aspects of the game play experiences. However, this required an approach to selfreporting as non-obtrusive, not taking too much of the players’ attention from the game activities as well as provide ease of use. To understand the challenges in introducing a new method into a gaming experience, I focused my research on understanding experience, which is a subjective concept. Even though there are methods aiming at capturing the physiological changes during game play, they don’t capture players’ interpretations of the gaming situation. By combining this with objective measurements, I was able to gain a comprehensive understanding of the context of use. The resulting designs were two tools, iteratively developed and pre-tested in a tabletop role-playing session before a test run in the pervasive game Interference. From my findings I was able to conclude that using self-reporting tools for players to use while playing was successful, especially as the data derived from the tools supported post-game interviews. There were however challenges regarding the design and functionality, in particular in outdoor environments, that suggests improvements, as well as considerations on the use of selfreporting as an additional method for data collection.

    Optimisation of Ad-hoc analysis of an OLAP cube using SparkSQL2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    An Online Analytical Processing (OLAP) cube is a way to represent a multidimensional database. The multidimensional database often uses a star schema and populates it with the data from a relational database. The purpose of using an OLAP cube is usually to find valuable insights in the data like trends or unexpected data and is therefore often used within Business intelligence (BI). Mondrian is a tool that handles OLAP cubes that uses the query language MultiDimensional eXpressions (MDX) and translates it to SQL queries. Apache Kylin is an engine that can be used with Apache Hadoop to create and query OLAP cubes with an SQL interface. This thesis investigates whether the engine Apache Spark running on a Hadoop cluster is suitable for analysing OLAP cubes and what performance that can be expected. The Star Schema Benchmark (SSB) has been used to provide Ad-Hoc queries and to create a large database containing over 1.2 billion rows. This database was created in a cluster in the Omicron office consisting of five worker nodes and one master node. Queries were then sent to the database using Mondrian integrated into the BI platform Pentaho. Amazon Web Services (AWS) has also been used to create clusters with 3, 6 and 15 slaves to see how the performance scales. Creating a cube in Apache Kylin on the Omicron cluster was also tried, but was not possible due to the cluster running out of memory. The results show that it took between 8.2 to 11.9 minutes to run the MDX queries on the Omicron cluster. On both the Omicron cluster and the AWS cluster, the SQL queries ran faster than the MDX queries. The AWS cluster ran the queries faster than the Omicron cluster, even though fewer nodes were used. It was also noted that the AWS cluster did not scale linearly, neither for the MDX nor the SQL queries.

    Designing an Information System for Open Innovation – Bridging the Gap between Individual and Organisational Creativity2011Doctoral thesis, monograph (Other academic)
    Abstract [en]

    History shows that those companies that continue to invest in their innovative capabilities during tough economic times are often those that prosper when growth returns. Recently, information systems (IS) have been harnessed to support innovation. Even with IS support, innovation campaigns and suggestion management systems often end up in failure. Employees and customers are reluctant to share their best ideas. Individuals interests, motivation, creativity and life-long learning are seldom adequately supported by companies. In the information systems research area there is very little research on creativity and creativity has traditionally been studied mainly within the decision support systems (DSS) research area. This DSS area has focused on rather mechanistic idea-generation processes lacking a focus on individuals and their creativity. Even in the emerging open innovation paradigm, individual and group levels have come in for little research. From these starting points, we became interested in ways to improve existing information systems and innovation practices. The research question here is: How to design an artefact to support learning and creativity within the open innovation paradigm. Since we are interested in building new artefacts, we will utilise design research methods, particularly the Design Science Research Methodology (DSRM) process model. Our three artefacts are the results of our work. The first artefact, the Mobile Personal Development Plan, is focused on extending development talks between an employer and employees within human resource management to support innovation. Curiosity and emerging interests are seen here as idea seeds and future competences. The second artefact, the iPortfolio, extends this with a life-long learning and problem-solving focus. The third artefact, the Brokering Platform for Open Innovation, finally focuses on collaboration with customers and crowds. The software development was time consuming in our work and only the first artefact is demonstrated as a functional software prototype. Our pilot in an SME company illustrates practical requirements and usability issues related to the software. Additionally, a Delphi study with international open innovation experts served to identify future related requirements. Given the lack of creativity research in the IS field, we claim that our work makes an appropriate contribution. To the design research literature our input is new usage cases of the previously mentioned DSRM process model. Our results apply to organisations, where the employees work in dispersed teams and need an information system to communicate their emerging ideas and interests for more systematic problem-solving. The managers in our study reported that there are plenty of ideas available, but the challenge is to ensure the commitment of external resources to the actual innovation building. The integration of learning into the innovation and problem-solving activity should be motivational. We therefore discuss human resource management in relation to creativity and innovation. Surprisingly, in our pilots we noticed difficulties in time management in mobile settings and the current health risk debate gradually changed our artefact design, so this work also provides a critical view on mobility and on the access anytime, anywhere phenomenon. Finally, we suggest improvements to existing innovation practices in organisations.

    Industrial Ecology Methods within Engagement Processes for Industrial Resource Management2013Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The global use of resources such as materials, energy, and water has surpassed sustainable levels by many accounts.  The research presented here was explicitly normative in its aim to improve the understanding of, and make sustainable change toward highly systemic issues of resource management.  The core methods chosen to work toward this aim were bottom up action research procedures (including stakeholder engagement processes) and industrial ecology analysis tools.  These methods were employed and tested in pragmatic combination through two of the author’s case study projects. The first case study, performed between 2009 and 2012, employed a multi-stakeholder process aimed at improving the cycling of construction and demolition waste in the Stockholm region.  The second case study produced a strategic tool (Looplocal) built for facilitating more efficient regional industrial resource networks. While the highly participative aim of the cases required a larger contribution of resources than that of more closed studies, it is arguable that the efficacy of approaching the project aims is improved through their employment.
