    Effektiv trafiksimulering: En jämförelse mellan A* och Internet Routing vid trafiksimulering2016Självständigt arbete på grundnivå (kandidatexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Trafiksimulering är vanligt förekommande i stadsbyggarspel, som t.ex. SimCity (2013), och innebär att bilar färdas mot ett bestämt mål, istället för endast visuellt presenterat utifrån statistik, som i tidigare stadsbyggarspel. Problemet med denna simulering är att antalet bilar ökar i takt med att staden växer, vilket innebär att simuleringen måste vara optimalt effektiv för att kunna köras i realtid.

    För att bilarna ska hitta till målet genomförs vanligtvis en genomsökning av vägnätet med en algoritm som heter A*, som lägger upp en väg till målet.Detta kan vara tidskrävande att simulera i realtid med många bilar. Detta arbete tar fram en ny metod som liknar hur data navigeras på Internet, kallat routing. Denna metod benämns Internet Routing.

    Metoden testades mot A* algoritmen och sedan jämfördes deras simuleringseffektivitet (FPS). Resultaten visade att det blev nästan samma FPS för båda. Slutsatsen är att den är likvärdig men mer komplex att implementera.

    EuroHCIR2013 - the 3rd European Workshop on Human- Computer Interaction and Information Retrieval2013Ingår i: Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval, New York: Association for Computing Machinery (ACM), 2013, s. 1139-1139Konferensbidrag (Refereegranskat)
    Abstract [en]

    The purpose of EuroHCIR is to push the agenda of understanding the role that HCI has with IR systems, beyond Interactive IR. Alongside the popular American HCIR series, EuroHCIR aims to stimulate this focus in the large European community. While the previous two workshops have taken place at more HCI focused conferences (BCS-HCI and IIiX2012), the particular purpose of running EuroHCIR2013 at SIGIR2013 is to better engage with the core IR community, on extended search scenarios like holiday planning, entertainment, and casual browsing.

    Abstract [en]

    EuroHCIR 2013 was organised with the specific goal of better engaging the IR community, who have been underrepresented at previous EuroHCIR conferences. Thus we proposed to have the workshop at the ACM SIGIR conference in Dublin. Research, Industry, and Position papers were invited, and although very few industry submissions were received, we received a number of research and position papers focusing on the intersection of IR and HCI evaluations, several focusing on adapting the TREC paradigm. Many interesting system and demonstrator papers were also accepted.

    Design av mobila gränssnitt genom operationalisering av användbarhetsprinciper2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    I aktuellt arbete undersöks nya metoder och tekniker som kan användas för att skapa användarvänlig design i mobila enheter. Det har efterfrågas metoder och verktyg för att kunna skapa användarvänlig design i mobila gränssnitt, då det finns ett behov inom detta unga område som binder samman mobila gränssnitt, användarvänlighet och design. Därför har teorier studerats som behandlar områden inom interaktionsdesign och exempelvis innehållande användarvänlighet, skrivna av inflytelserika interaktionsdesigners som Alan Cooper . En sammanställning av designprinciper och användarvänlighetsprinciper baserades på en omfattande litteraturstudie, och har härefter lätt fram till en operationalisering som i undersökningen bildar, agerar och definieras som ett designverktyg. Detta verktyg har funktionaliteten att utgå från ett webbaserat gränssnitt och med hjälp av verktyget kan designern få hjälp att omforma detta till ett gränssnitt för mobila enheter. Designverktygets funktionalitet och pålitlighet har sedan genom en fallstudie test körts och genererat goda resultat. Arbetet har således visat att genom att sammanställa teori från området interaktionsdesign till en operationalisering så har ett välfungerande och pålitligt designverktyg för mobil design skapats. Detta designverktyg kan härefter användas av designern att omforma och anpassa design för mobila gränssnitt. Undersökningen bidrog också till en ökad förståelse för användarens deltagande i designprocessen. Med hjälp av verktyget genererades genom en fallstudie för en mobilwebbapplikation dessutom ett designförslag till en design för ett mobiltgränssnitt, denna fallstudie styrker hur väl fungerande designverktyget faktiskt är.

    An automatic assessment scheme for steel quality inspection2000Ingår i: Machine Vision and Applications, ISSN 0932-8092, E-ISSN 1432-1769, Vol. 12, nr 3, s. 113-128Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper presents an automatic system for steel quality assessment, by measuring textural properties of carbide distributions. In current steel inspection, specially etched and polished steel specimen surfaces are classified manually under a light microscope, by comparisons with a standard chart. This procedure is basically two-dimensional, reflecting the size of the carbide agglomerations and their directional distribution. To capture these textural properties in terms of image features, we first apply a rich set of image-processing operations, including mathematical morphology, multi-channel Gabor filtering, and the computation of texture measures with automatic scale selection in linear scale-space. Then, a feature selector is applied to a 40-dimensional feature space, and a classification scheme is defined, which on a sample set of more than 400 images has classification performance values comparable to those of human metallographers. Finally, a fully automatic inspection system is designed, which actively selects the most salient carbide structure on the specimen surface for subsequent classification. The feasibility of the overall approach for future use in the production process is demonstrated by a prototype system. It is also shown how the presented classification scheme allows for the definition of a new reference chart in terms of quantitative measures.

    Duplicate systems: investigating unintended consequences of information technology in organizations2011Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The organizational consequences of information technology (IT) constitutes a core focus in information systems (IS) research. The relationship between organizations and IT has received considerable attention by IS researchers in order to develop knowledge related to how and why organizations and IT are related. While organizational use of IT continues to increase in practice, previous research has shown that the effects of IT at best are difficult to predict. Consequently, the adoption and assimilation of IT in organizational settings must be recognized as complex and challenging processes, which makes the production of knowledge related to such processes important and pressing.

     

    This dissertation identifies, characterizes and explains a paradoxical outcome of the adoption and assimilation of an enterprise content management (ECM) system in a context of organizational information management. The outcome, labeled the duplicate systems paradox, is constituted by a situation in which an organization continuously allows multiple, overlapping, partially competing and largely incompatible information systems to persist and continue to evolve over time, despite continued awareness of the adverse consequences on organizational information management capabilities. A qualitative case study approach was used as the primary means for data collection. The case study was conducted in the administrative divisions of HealthOrg, a large organization in the medical- and health care sector. To this end, the main objective of this dissertation is to investigate how this paradox was formed, and furthermore, how and why it was able to persist. In order to do this, dialectical theory is combined with contextualism and theory on organizational information processing to form a comprehensive theoretical perspective used to inform the analytical efforts.

     

    By using a dialectical approach, the analysis presents empirical evidence of the existence and composition of three overarching contradictions found to affect the formation and persistence of the duplicate systems paradox. More specifically, the resulting explanatory model demonstrates how three pairs of opposites, control versus support at the requirements level, options versus practices at the solutions level, and top-down versus bottom-up approaches at the transformations level, along with contextual tensions, were essential components in the formation and persistence of the paradox. Thus, the duplicate systems paradox could form and continue to evolve due to contradictory forces present at, and interconnected between, different vertical and horizontal levels within the organization. Through the identification and explanation of the duplicate systems paradox, this study provides a detailed example of how, and why, unintended consequences of IT in organizations may emerge and continue over time.

     

    In terms of implications for research and practice, the findings of this dissertation point to six important observations. First, this research suggests that understanding and characterizing the context in which IT is to be implemented is crucial and challenging. Thus, organizations should pay careful attention to the practical side of context, rather than to the somewhat theoretical boundaries of organizations. It is suggested that the concepts of ‘inner’ and ‘outer’ context may be useful in analyzing and understanding context. Second, this research suggests that organizations should attempt to identify potentially conflicting requirements, and devise clear strategies to decide how to prioritize between such requirements as the identification and explication of requirements present at different levels in the organization may reveal problems that need to be considered when choosing information system (IS). Third, organizations need to pay careful attention to what the adoption of a new IS means in terms of adaptation and/or realignment, and to what extent organizational activities, technological functionalities, or both, should be adapted. Organizations should furthermore be aware that the adoption of systems that can also be used as development platforms may cause a cascade of effects and dependencies that are difficult to manage. Fourth, the findings of this research suggest that organizations faced with the challenge of adopting complex IT solutions need to take into account their previous strategies and planned new ones in order to devise a comprehensive strategic approach since the coexistence of radically different strategies may cause uncertainty and inertia within the overall assimilation process. Fifth, this research indicates that IT management and information management (IM) are highly interrelated activities, but are not mutually exclusive. Thus, organizations adopting technologies that are specifically focused on information management may benefit from developing distinct areas of responsibility and clear communication channels between the involved organizational units. Furthermore, these findings suggest that future research should pay careful attention to, and specifically investigate, the exact nature of the relationship between information management and IT management. Finally, this research demonstrates how a dialectical approach may be used to adequately investigate organizational information management, specifically in relation to the adoption and assimilation of IT.

    Fundamentals of user perception and interaction: environmental psychology applied in a study of web pages2004Ingår i: PsychNology Journal, ISSN 1720-7525, E-ISSN 1720-7525, Vol. 2, nr 3, s. 282-303Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper explores the possibility of using theories and concepts from the field of environmental psychology as a framework for understanding perception of- and interaction with web pages. A qualitative pilot experiment has been conducted in order to investigate potential similarities in how people interact with, and perceive web pages and real world environments. This study indicates that perception of web pages is very similar to perception of natural environments. Many key factors that have proven to be important in perception of natural environments, such as complexity, spatial configuration and mystery, also appear to be relevant determinants in perception of web pages. Further, it also seems likely that interaction with web pages, to some extent can be described using a model based upon a conceptual framework depicting habitats selection.

    What are the future possibilities of eDemocracy?: A discussion paper2007Ingår i: Electronic Government, Proceedings, 2007, Vol. 4656, s. 401-411Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    This paper presents some future possibilities for eDemocracy tools and considers how these new technologies might conflict with our basic assumptions about what democracy should be. I hope this paper will contribute to discussion of under what situations different forms of eDemocracy are appropriate. The possibilities and repercussions of user profiling, voting outside of polling booths, longer decision-making periods, changeable election results and weighted voted are considered. Although none are necessarily advisable, this paper suggests they might be interesting to consider.

    Publika trådlösa nätverk: Man-in-the middle attacker och skydd2015Självständigt arbete på grundnivå (högskoleexamen), 5 poäng / 7,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Åtkomst till internet via trådlösa nätverk ses som en självklarhet för användare med tillgång till mobil, dator eller annat typ av utrustning som kan skicka eller mottaga datatrafik. Det har gjort att utvecklingen samt tillgängligheten av trådlösa nätverk har blivit mer utbredd. Antingen via privatpersonens egna hem, via sin arbetsplats eller skola samt företag som bedriver tillfälliga boende som hotell, café eller andra platser som erbjuder internet via sitt privata nätverk. Med den ökade tillgängligheten ökar även säkerhetsrisken för användaren antingen från yttre hot där användare vill få tillgång till andra användares data eller direkt attack från ägaren av nätverket. Användare kan känna sig säkra med de skydd som finns tillgängliga som exempel antivirus och brandvägg men i och med att ansluta till ett publika nätverk kan en rad nya säkerhetshot uppstå i former av man-in-the middle attacker mot användaren. Lyckade attacker skulle kunna resultera i att användare blir avlyssnade eller bestulen på känsliga information och eventuellt utan att användare märker av det eller innan det är försent. En litteraturstudie har genomförts för att undersöka säkerheten för användaren på platser som erbjuder en tjänst att få tillgång till internet via en accesspunkt. Studien ska se över de säkerhetshot som finns när användare ansluter trådlöst till ett publikt nätverk, vilka hot som kan riktas mot användaren som använder nätverket och slutligen vilka tjänster som finns tillgängliga för användaren för att öka sin säkerhet vid användning av nätverket.

    I vilken utsträckning utnyttjar två svenska klädföretag de rekommendationer som finns på Facebook och Instagram?2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Den här studien undersöker hur två svenska klädföretag använder sin Facebook-profil och sitt Instagram-konto i marknadsföringssyfte. Syftet med undersökningen är att besvara frågan: I vilken utsträckning överensstämmer innehåll och form i företagens marknadsföring på Instagram och Facebook med plattformarnas tänkta användning för inlägg? Metoder som använts för att besvara problem-formuleringen är en litteraturstudie, observationer av företagens profiler samt en enkätstudie som skickades ut till företagens butikspersonal. Resultaten visar att företagen till största del följer plattformarnas riktlinjer med några undantag. Slutsatsen som kan dras ur undersökningen är att de riktlinjer som finns för de sociala medierna är mycket vaga. Vi anser att det beror på att de är relativt nya sätt för marknadsföring som behövs studeras vidare för att kunna sätta mer konkreta riktlinjer.

    Prototyping för effektiv kravutvinning1998Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats
    Abstract [sv]

    Vid utveckling av datoriserade informationssystem är kvaliteten och därmed kostnaden på slutprodukten i hög grad beroende av hur väl man har lyckats att realisera kundens krav och önskemål på det tänkta systemet. För att kunna realisera kundens krav måste först de krav som kunden har på systemet komma till kännedom för utvecklaren. Kunden är inte heller alltid förmögen att ställa samtliga krav då han eller hon inte vet vad som är möjligt att kräva av systemet. Som stöd för utvinningen av kundkrav finns ett antal olika metoder och ansatser. Samtliga av dessa metoder har dock brister och begränsande egenskaper som påverkar deras effektivitet för att utvinna samtliga kundkrav för ett tänkt informationssystem.

    Den metod som kritiskt analyseras i denna studie är prototyping. Närmare bestämt throw-away prototyping. Prototyping är en kravutvinningsmetod som utnyttjar prototyper av det tänkta systemet som grund för kravutvinningen. Detta förfarande främjar dialogen mellan användare och utvecklare då man har något konkret att tala omkring samt att användarna får en förståelse vilka krav som är möjliga att ställa på systemet. Dock har metoden vissa egenskaper som begränsar dess lämplighet vid utveckling av vissa informationssystem.

    Jag har utifrån en litteraturstudie behandlat frågeställningarna; vilka begränsande egenskaper har prototyping och när uppkommer dessa egenskaper, hur påverkar typen av informationssystem, som skall utvecklas, lämpligheten för prototyping samt vilka faser i systemutvecklingsarbetet påverkas tillföljd av dessa begränsningar? Jag har dessutom gjort en bedömning när det kan vara lämpligt att använda sig utav prototyping i avseende på totalkostnaden för ett projekt. Det är inte en jämförande studie mellan olika metoder utan en studie som enbart behandlar prototyping.

    Informationsarkitekturens påverkan vid e-handel2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

     Purpose – The purpose of this report is to increase understanding of the importance of good

    information architecture on e-commerce sites and to evaluate how far one overlooks poor

    information architecture as acceptable if one finds the product they intend to buy attractive.

    The aim has resulted in two questions that read:

    What are the rules and the framework for good information architecture?

    How will people's purchasing behavior be affected of the information architecture of

    an e-commerce website, if it is designed based on the rules and frameworks available?

     Method – The methods used have been literature studies, a comparison of the two ecommerce

    sites, and user tests and interviews. The methods have been used to find literature

    in the area and to give substance to this investigation. The empirical intends to answer further

    questions and provide a greater depth to the report.

     Findings – The most important parameter of the result has been that you have to give

    navigations systems your number one priority when it comes to developing e-commerce

    websites. Without satisfactory navigation for the visitor he or she will choose to cancel a

    planned purchase and leave the website. If the navigation, and in this case, the information

    architecture is not satisfactory for the visitor, then the design of the website will play a very

    small role if the visitor chooses to stay or not. A good design cannot compensate for poor

    information architecture but good information architecture will make the visitor accept an

    inferior design.

     Implications – The implications of the report could be that, by the result you can see that

    the navigation is more important than the design. This would in turn lead to that developers

    should spend more time on designing a good navigation system rather than on the actual

    design it self.

     Limitations – The report has only taken into account two e-commerce sites selling

    applicable to others. Had there been a bigger financial budget for the study and if the survey

    had been widened and a greater number of people interviewed the credibility of the report

    would have been greater. Furthermore, the credibility would have been greater by the

    Dealing with conflicting user interface properties in user-centered development processes: IFIP WG 13.2 + 13.5 workshop at INTERACT 20172017Ingår i: 16th IFIP TC13 International Conference on Human–Computer Interaction, INTERACT 2017, Springer, 2017, Vol. 10516, s. 521-523Konferensbidrag (Refereegranskat)
    Abstract [en]

    Whilst usability has been the most prominent user interface property in early Human-Computer Interaction (HCI) research other properties such as accessibility, inclusive design, user experience and, more recently security, trust and resilience (among many others) might also be important for the development of interactive system. It is interesting to notice that user interface properties might overlap and sometimes create conflicting recommendations. A good example is security which, by recommending users to deal with passwords reduces system usability by placing a burden on users. The ultimate goal of this workshop is to promote the investigation of multiple user interface properties in a user-centered design process. We are concerned by theories, methods and approaches for dealing with multiple user interface properties when developing interactive system. This workshop is organized by the IFIP WG 13.2 on Human-Centered Software Methodologies and the WG 13.5 on Resilience, Reliability, Safety and Human Error in System Development.

    Musikens maskuliniteter: En kvalitativ studie kring könshierarkier i musikbranschen ur ett feministiskt perspektiv2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Uppsatsen faller inom ämnesområdet musikproduktion, där yrket musikproducent

    studeras ur ett feministiskt perspektiv. Studien utgår från att kvinnliga

    musikproducenter är underrepresenterade i Sverige och att musikproduktion i större

    drag är synonymt med manlighet. Med utgångspunkt av Equalizerprojektet, vars mål är

    att på snabbare sikt göra musikbranschen mer jämställd, syftar den här studien till att

    analysera manliga musikproducenters tankar och upplevelser av branschen.

    Genom en kvalitativ metod har semistrukturerade intervjuer gjorts med fyra verksamma

    manliga musikproducenter under november månad år 2017. Respondenternas

    reflektioner har sedan analyserats utifrån pionjärer inom feminism och

    maskulinitetsforskning. Genom dessa teorier får vi en inblick i komplexa hierarkier, där

    män kategoriseras i underordnade, överordnade och delaktiga maskuliniteter, varpå

    några av dessa maskulina beteenden är med och bidrar till en icke jämställd

    musikbransch.

    Efter studien konstateras att samtliga respondenter tillhör en underordnad maskulinitet

    där de själva anser sig vara besvärade av en dominant manlighet som är starkt rådande

    inom yrket. De upplever att det ger utdelning att anamma samma starka maskulina

    jargong, vilket bidrar till att den dominanta maskuliniteten upprätthålls. Två av

    respondenterna påvisar en stark feministiskt medvetenhet, både på strukturell nivå samt

    individnivå. Resterande respondenter visar en positiv inställning till att musikbranschen

    bör bli mer jämställd, samtidigt som de själva anser att de skulle kunna göra mer för att

    förändra rådande strukturella normer.

    Visible Light Communication as a material for design2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    ”Kommunikation med synligt ljus” (VLC) som ett design material är ett komplement till ”radio frekvens kommunikation” och har många applikationer inom trådlös kommunikation, Inomhuspositionering, och situationer där RFC inte är applicerbart. Problematiken med teknologi är att den ofta inte är synlig, och därför är svår att inkludera i dagens design processer. För att designers ska kunna använda sig av VLC i deras kreativa process, utgår denna studie från ”Inspirational Bits” förhållningsätt till design, och ämnar utforska följande frågeställning:

    Hur kan vi designa artefakter som tillåter designers att engagera sig i en konversation med ”kommunikation med synligt ljus” (VLC) som ett design material?

    Genom ”konstruktiv designforskning”, studerades prototyper av teknologin följt av analys. Processen upprepades med ett flertal modeller. Prototyperna utvärderades i två design-workshops, genom observation av och respons från 11 deltagare.

    Som resultat, byggdes sju stycken artefakter för att belysa sju stycken potentiella materiella egenskaper av VLC. Observationerna och den samlade responsen visade också att artefakterna hjälpte designers att få taktil kunskap om VLC. Artefakterna baserades på ”the Arduino Platform” och elektriska standard komponenter. En biprodukt av denna studie är ”the lumoino toolkit for tinkering and prototyping with VLC”. Eventuella styrkor och svagheter diskuteras och stycket framtida arbete visar potentiella utvecklingar och expantioner av ”the lumoino toolkit”.

    Abstract [en]

    Communication through visible light (VLC) is gaining ground as an alternative to traditional radio communication in many settings. Effectively using VLC in creative design processes may however be difficult as the material properties of VLC can be hard to grasp and therefore to use. This paper presents a design exploration where a set of artifacts was created to enable designers to play around with VLC and better understand its properties and their potential use for design. Each artifact was designed to illustrate a particular property of light communication ranging from inner workings of transmission protocols to properties of light in itself. The set was used in two small scale workshops where users played around with the artifacts and afterward were interviewed about their experiences. Interviews and observations from the workshops suggest that users gained insights into the material properties of light communication and were also inspired to think of creative uses for VLC based on those insights

    3D-visualisering av robotsimulering2001Självständigt arbete på grundnivå (yrkesexamen)Studentuppsats
    Abstract [en]

    Visualization is a rapidly growing area of computer graphics. Due to the very progressive development of computer technology and especially 3D-graphic boards yesterdays imagination of visualizations, today is a reality.

    At Saab Bofors Dynamics in Linköping missile systems are developed. Through the development, different subsystems are simulated before the manufacturing starts. The results of these simulations have to be visualized to get a meaning. The visualizations can be symbolic or more real looking 3D-visualizations.

    During the work an investigation of available tools for computer visualizations on the market has been conducted. The outcome of the investigation has later been the foundation for the selection of tools to solve the visualization task.

    One 3D-visualization application for general 3D-visualization has then been developed using two different 3D-APIs, and the experiences of these have then been analyzed.

    A web portal with usersubmitted content: Creating a web portal and minimizing its need for administrative work2017Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    En webbportal som publikt visar användarskapat innehåll kräver administration för att försäkra att oönskat innehåll, som potentiellt är illvillig, exkluderas. Andra administrativa aspekter som medföljer en webbportal med användarskapat innehåll, inkluderar användarsupport och underhåll av tjänsten. Detta projekt skapades delvis för att utveckla en ny version av en redan existerande webbportal som används för annonsering av examensarbeten.Målet med projektet är att utveckla en förbättrad version av den gamla webbportalen och försäkra att den nya versionen kräver så lite manuellt administrativt arbete som möjligt. Hur minimering av administrativt arbete åstadkoms för denna typ av tjänst ansågs vara okänt, därav valdes ett induktivt tillvägagångssätt till detta projekt för att undersöka hur mängden administrativt arbete minimeras för en webbportal vars innehåll skapas av dess användare.

    Projektet resulterar i presentationen av en webbportal med ny funktionalitet med modifieringar inom olika aspekter beroende på det som efterfrågats av projektbeställaren. Visuella uppbyggnaden presenteras tillsammans med information angående vilka delar som återanvändes från den gamla version av webbportalen. Designval med fokus på minimering av administrativt arbete samt även generella designval som ansågs viktiga, presenteras och motiveras. Slutligen drar studien slutsatsen att möjliga områden där det administrativa arbetet kan reduceras till stor del beror på kraven satta för webbportalen och att metoderna som användes i denna studie var framgångsrika i att identifiera de aspekter av administrativt arbete som kan reduceras eller elimineras från webbportalen som utvecklades i detta projekt. Slutsatsen dras även att tillräckligt sofistikerade automatiska system kan vara användbara för att reducera administrativt arbete för webbportaler med användarskapat innehåll.

    Collaboration and Coordination Challenges in Patient-Centered Care: Models and Informaion Services2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis reports on research focuses on how to deal with the fact that the organization and processesof today’s health and social care are becoming ever more complex as a consequence of societal trends, including an aging population and an increased reliance on care at home. The overall research goal is to suggest ways in which IT-based solutions can enable and leverage collaboration and coordination insituations where a co-morbid patient is subject to care delivered simultaneously by several different professionals and organizations.

    Patient-centered care is defined as quality health and social care achieved through a partnership between informed and respected patients, their families, and coordinated health and social care teams who conduct care activities according to jointly determined care plans.

    Against a background of several years of research on patient-centered collaborative care using adesign science approach, using techniques such as focus groups, interviews, and document studies, the author of the thesis has further pursued the work in a project named CoCare. Results show that the care required in aging societies is both a social and a technical challenge. Meeting this challenge will require a redesign of today's health and social care processes in order to focus more clearly on patient needs and values, and poses demands on information services allowing to share knowledge of the patient’s health and social situation among involved care providers. An important aspect of the increased complexity is that a single patient may need care from several autonomous care providers in parallel, particularly patients with co-morbidities. This clearly requires effective coordination of care activities, which poses further demands on information services to support this task.

    A set of issues involving patient-centered collaborative care is identified and analyzed. The thesis introduces the notions of the Patient-Centered Care Process (PCCP) and a conglomeration of suchprocesses. A conglomeration comprises a set of PCCPs that concern the same patient, that are overlapping in time, and that share the overall goal of improving and maintaining the health and socialwell-being of the patient. The PCCP is inspired by the well-known PDCA cycle and comprises the four phases of assessing the patient situation (ASSESS), planning care activities (PLAN), performingcare activities (DO) and following up care (CHECK) for the patient. Based on a number of key standards, such as HL7, HISA and CONTsys, the thesis introduces a Patient-Centered Information Model (PCIM). A set of information services, together constituting a Coordination Hub, is proposed. The information services aim to help formal as well as informal carers (including the patient) inconducting care according to the PCCP

    The thesis contributes to a deeper understanding of care processes and suggests ways to achieve patient-centered collaborative care that better contributes to creating value for the patient as an individual.

    Abstract [en]

    As more public organizations aim to move to the stage of transformational Government, the need for ‘single point of contact” increases dramatically on local, regional and national government levels. This paper contributes to literature by reporting the findings from three case studies of Swedish local government who has reached, or intend to reach, the transformational stage of e-Government. Using a grounded theory approach, information about the municipalities was collected and analyzed from the perspective of goals, implications and change management. The paper reports on the opportunities aimed for and experienced by the municipalities as well as the organization-al, technical and legal challenges faced by them. Finally we make five prop-ositions, based on the learning from the case studies, on how to manage changes related to implementing single point of contact in local government.

    Abstract [en]

    The organisation and processes of today’s health and social care are becoming ever more complex as a consequence of societal trends, including an ageing population and an increased reliance on care at home. One aspect of the increased complexity is that a single patient may receive care from several separate care providers, which easily results in situations with potentially incoherent, uncoordinated and interfering care processes. In order to describe and analyse such situations, the paper introduces the notion of a process conglomeration. This is defined as a set of patient care processes that all influence the same patient, which are overlapping in time, and that all have the goal of improving or maintaining the health and social wellbeing of the patient. Problems and challenges of process conglomerations are investigated using coordination theory and speech act theory. In order to address the challenges, a number of information services are proposed.

We investigate the need for improved communication and collaboration on different managerial and operational levels. In particular we point to the need for managers in different organizations to agree on ways of communicating and collaborating between the operational level and the importance of this during procurement of home care services. As a result the paper suggests a number of methodological measures, strategies and IT solutions, to support organizational development, coordination and collaboration.

    Abstract [en]

    This paper describes and discusses the situation for a typical patient with multiple illnesses and how his case would benefit from improved coordination, communication, and collaboration among all involved care providers. The paper is built around a patient case presented in a current scenario. The authors identified that for a single patient with several problems and diagnoses and the involvement of several care actors, the common issues concern lack of collaboration, lack of coordination, and awareness of what others have done to assess, plan, perform, and evaluate care. This presumably leads to a lack of care quality and a lack of effective use of care resources. The scenario and the findings are based on a patient-oriented perspective, on an analysis expressed in focus groups, and on interviews with key actors in health and social care. The paper also discusses the fact that an increasing number of patients are treated in their homes by a variety of organizations, and how this fact raises new and more intense demands on the various stakeholders forming the care staff to collaborate and coordinate care. We point to the need for managers in and between organizations to agree on the ways of collaborating at the operational level. Most importantly, by taking a basic set of issues as the starting point for reasoning, we derived a set of related problems and suggest solutions to deal with these. The literature currently lacks scenario descriptions that put the patient's situation into focus with respect to collaboration between health and social care. Finally, the paper presents a future case for collaboration including support by new e-services.

    This paper discusses the fact that more and more patients are treated in their homes by a whole set of organizations, and how this fact places new and more intense demands on health and social care staff to communicate and collaborate. The aim of the paper is to further explore the detailed needs for collaboration between different care units, individuals and professions, and to outline organizational and/or IT-based solutions. The suggested solutions are based on a patient and process oriented perspective and on an analysis of needs and issues expressed in interviews with key actors in a number of research projects focused on collaboration in care. We point to the need for managers in different organizations to agree on ways of communicating and collaborating on the operational level over sectors and units and how this aspect has to be taken into account already during procurement of care services. Most importantly, by reasoning from a basic set of issues, we derive a set of related problems and suggest solutions for how to deal with these. The solutions include suggestions for various e-services aimed at improving coordination and collaboration among care personnel.

    The Quest for Equilibrium: Towards an Understanding of Scalability and Sustainability for Mobile Learning2008Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The research presented in this thesis investigates the concept of sustainability in relation to mobile learning initiatives. Sustainability is seen as a key concept for mobile learning to gain acceptance. In linking sustainability to scalability, a term used to describe how well something can grow to suit an increasing complexity, a representation of this process is provided. In this thesis, this process is called ``the quest for equilibrium.''

    A study was conducted of an actual mobile learning initiative that involved introducing podcasts as a supplement to traditional lectures in higher education. In following this initiative, thorough data gathering was conducted, utilizing the process of iterative cycles that characterizes the action research approach. In accordance, a literature survey was conducted, whereby leading publications in mobile learning were classified and analyzed according to the following criteria: Reflections, Frameworks, Scalability, and Sustainability.

    As the mobile learning system evolved from idea to an actual empirical study, trying to understand this process became important. The insights gained during this research were used to develop a conceptual model that is based on the notion that the two concepts of Scalability and Sustainability can be linked to each other.

    This conceptual model is presented describing how a mobile learning system evolves, from Idea, to Experiment, to Project, to Release. Further, each of the stages in this evolution is described by using four areas of concern: Technology, Learning, Social, and Organization.

    Using the experience from a specific mobile learning initiative to define a conceptual model that then is used to describe the same initiative, was a way to bring together practice, theory, and research, thus provide reliable evidence for the model itself.

    The conceptual model can serve as a thinking tool for mobile learning practitioners, to help address the complexity involved when undertaking new efforts and initiatives in this field.

    Understanding Scalability and Sustainability in Mobile Learning: A Systems Development Framework2009Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The rapid development of mobile technologies combined with access to content almost everywhere and every time allows people to experience new situations regarding learning in a wide variety of situations. Mobile learning brings the promise of learning "on the move" by allowing learners to take control over time and space, thus making learning "more natural". The field of mobile learning has rapidly evolved in the last ten years and many initiatives have been conducted worldwide. However, research results indicate that few of these efforts have produced any lasting outcomes. It is evident that these initiatives are faced with inherently complex settings and that the outcomes might not live up to their prom- ises; will not be adopted and, hence, will not become sustainable.

    Many of the complex issues faced by mobile learning initiatives are similar to those faced by the development of information systems. This latest statement suggests that an improved development practice might hold one piece of the key to sustainable mobile learning. The aim of the research presented in this thesis is to investigate the relation between information systems development practice and mobile learning development; and if methods and models originated within information systems development can be used to strengthen mobile learning initiatives. In order to investigate this relation, this thesis studies several mobile learning initiatives with a particular focus on how and why development and research was initiated and conducted. Concepts found in mobile learning practices are strengthened by providing a theoretical perspective with roots in information systems development. The outcomes of the studies presented in this thesis indicate that the development practice of mobile learning initiatives can be redefined in order to achieve more sustainable results.

    The core of this thesis consists of eight peer-reviewed scientific publications that have been presented at different international conferences. Five of the papers explore the field of mobile learning and its practice while the other three publications present the central ideas that serve as the basis for the proposed framework, how it has been developed, and the motivations behind its creation.

    The main contribution of this thesis is a novel development framework aimed at researchers and practitioners in the field of mobile learning. The framework defines the life-cycle of a mobile learning initiative and identifies the importance of emphasizing the concepts of scalability and sustainability during the development process. This may be a way to reduce the complexity inherent to mobile learning and its settings, and a means to improve the outcomes of coming mobile learning initiatives in terms of long lasting usable results.

    Abstract [en]

    Students and teaching staff in higher education are constantly looking for new tools to help them study and teach more efficiently. The University of Canterbury began ProjectPodcast to introduce podcasting to a number of subjects as an add-on to the current course curriculum. Podcasting is being used to enhance mobile learning and enthuse both students and lecturers. Previous podcasting evaluations show that there exists a need for both audio content from lectures, or so called “LectureCasts” as well as supplementary material or “Sup!Casts”. In this study, the evaluation of ProjectPodcast will be performed in-house. We have chosen an established six step methodology to avoid criticisms that often arise when evaluations are performed by internal members of the project. The evaluation is aimed at both the student population as well as the lecturing staff in order to gain knowledge about their impressions of podcasting. Prior podcasting

    surveys have received low response rates, due to the choice of time, location and medium. Hence, our evaluation plan has been created with the goal of encouraging feedback from students and lecturers. In this paper we present our preparatory plan for evaluating ProjectPodcast.

    Podcasts as a Supplement in Tertiary Education: An Experiment With Two Computer Science Courses2009Ingår i: Podcasting in Education / [ed] Mahashabde, K.E., India: ICFAI Books , 2009, 1Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    The current generation of undergraduate students are enthusiastic adopters of mobile technologies, and some of these technologies offers significant opportunities for broadening the times, places and manner that students study and learn. One of these is podcasting, which greatly eases distribution of content to portable devices, giving the students opportunity for anytime, anywhere learning. However, most educational podcasts do not take advantage of the potential of podcasting. In this paper we discuss the issues surrounding the use of podcasting for higher education. We report our experiences using podcasts to supplement two undergraduate Computer Science courses, and we provide tips for others considering the use of podcasts in education.

    A Framework to Guide and Structure the Development Process of Mobile Learning Initiatives2010Ingår i: Proceedings of the 9th World Conference on Mobile Learning, 2010, s. 184-191Konferensbidrag (Refereegranskat)
    Abstract [en]

    Mobile learning has yet to move on from small-scale trials to sustained deployment. One reason for this is the highly complex and multi-disciplinary setting that the initiatives operate within. They must deal with a wide range of issues such as software, hardware, people, learning, organizations and so on. At the same time, there is little support. Few frameworks to guide the development process exist. This article presents one such framework that was developed based on theories from software and systems development as well as practical experience from mobile learning. The framework divides the development into four Areas of Concern and introduces a life cycle of the mobile learning initiative. It further offers means to guide the development of the initiative and to find key issues that needs to be addressed in order to achieve sustainability. The framework presents a holistic view of mobile learning and is designed as an aid to all practitioners in mobile learning, no matter their background.

    A Meta-model Describing the Development Process of Mobile Learning2009Ingår i: Advances in Web Based Learning: – ICWL 2009 / [ed] Spaniol, M., Li, Q., Klamma, R., and Lau, R., Berlin / Heidelberg: Springer , 2009, s. 454-463Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    This paper presents a meta-model to describe the development process of mobile learning initiatives. These initiatives are often small scale trials that are not integrated in the intended setting, but carried out outside of the setting. This results in sustainability issues, i.e., problems to integrate the results of the initiative as learning aids. In order to address the sustainability issues, and in turn help to understand the scaling process, a meta-model is introduced. This meta-model divides the development into four areas of concern, and the life cycle of any mobile learning initiative into four stages. The meta-model was developed by analyzing and describing how a podcasting initiative was developed, and is currently being evaluated as a tool to both describe and evaluate mobile learning initiatives. The meta-model was developed based on a mobile learning initiative, but the meta-model itself is extendible to other forms of technology-enhanced learning.

    A Survey of Research Methods and Purposes in Mobile Learning2011Ingår i: International Journal of Mobile and Blended Learning, ISSN 1941-8647, E-ISSN 1941-8655, Vol. 3, nr 1, s. 1-18Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this paper we present a survey of published research in mobile learning. We investigated 114 papers from mLearn 2005, 2007, and 2008, and classified them according to two dimensions: research method and research purpose. Research methods and purposes are important parts of how research is conducted. Alas, opinions and approaches towards research differ greatly. The classified papers are evenly distributed among the research methods investigated, with one exception, being few in Basic research. In terms of research purpose, papers aimed to describe the research were well represented while there was a lack of papers targeting evaluation. Papers recounting both Basic research and research done to evaluate are imperative since they help a research field to mature and also help researchers to avoid repeating known pitfalls. This maturity, in turn, will lead to better scalability and sustainability for future research efforts in the community of mobile learning.

    Addressing Sustainability for Research Initiatives in Mobile Learning through Scalability2009Ingår i: Proceedings of the 8th IASTED International Conference on Web-Based Education / [ed] Uskov, V., ACTA Press, 2009, s. 7-12Konferensbidrag (Refereegranskat)
    Abstract [en]

    Understanding research initiatives in the field of mobile learning involves dealing with complexity. It is important to gather knowledge on how to nurse these attempts. To develop ideas and reach wide deployment of novel mobile learning is of great value. In this paper there is a discussion of the factors that describe attributes of mobile learning research initiatives and an investiga- tion of whether these are sustainable or not, and what this means. Sustainability for mobile learning initiatives is essential for the wide acceptance from both public and academia. The paper also addresses scalability of mobile learning research initiatives. Scalability is a term used to describe how well something can grow to suit an increasing complexity, and is addressed as a possibility to reflect on good ideas. Scalability is important in order to reach sustainability. Finally, this paper introduces a model that illustrates the evolutionary life cycle of a mobile learning research initiative. The model presents four evolution stages and these are: Idea, Experiment, Project, and Release.

    Asked and Answered: Communication Patterns of Experts on an Online Forum2013Ingår i: Proceedings IRIS36: August 11-14 2013 at Gran, Norway, 2013Konferensbidrag (Refereegranskat)
    Abstract [en]

    The notion of network structure for social relations dates back half a century. Nowadays people form social networks offline as well as online. At an online community people are connected trough information exchange of sorts. Interest groups form often forums to aid each other and discuss things. Programmers are no exception and a question and answer site called Stack Overflow has been up and running since 2008. Our focus is to find patterns of how people interact on this online community and see if we can find expert users. We find 4 different ways to categorize experts, which result in different rankings. We also investigate how expertise is divided among topics, and find some overlap with the global ranking.

    Bringing a Framework to Tackle the Development Process in Mobile Learning2009Ingår i: Proceedings of the 15th International Conference at Centre for Philosophy, Technology, and Social Systems / [ed] Basden, A., Haftor, D., and Grobler, L.M.J., 2009Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents a study that was conducted of the devel- opment process of an initiative that used podcasts (i.e., digital audio-files) to supplement lectures in higher education. A thorough data gathering was conducted using the iterative cycles of the action research approach. The empirical data was analyzed and this analysis resulted in a framework that shows how sustainability and scalability are linked. The framework also shows how an initiative is developed from Idea, to Trial, to Project, to Release, and how each of these stages can be described using four areas of concern, namely, Technology, Learning, Social, and Or- ganization. Using the experience from a specific mobile learning initiative to define a framework that is then used to conceptualize the development process is a way to bring together practice, theory, and research, and thus provide reliable evidence for the framework itself. The framework captures the development process and the relevant context in a unified theoretical attempt and is suitable for practitioners dealing with initiatives in the field of mobile learning.
