    Mining Candidates for Adverse Drug Interactions in Electronic Patient Records2014Ingår i: PETRA '14 Proceedings of the 7th International Conference on Pervasive Technologies Related to Assistive Environments, PETRA’14, New York: ACM Press, 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Electronic patient records provide a valuable source of information for detecting adverse drug events. In this paper, we explore two different but complementary approaches to extracting useful information from electronic patient records with the goal of identifying candidate drugs, or combinations of drugs, to be further investigated for suspected adverse drug events. We propose a novel filter-and-refine approach that combines sequential pattern mining and disproportionality analysis. The proposed method is expected to identify groups of possibly interacting drugs suspected for causing certain adverse drug events. We perform an empirical investigation of the proposed method using a subset of the Stockholm electronic patient record corpus. The data used in this study consists of all diagnoses and medications for a group of patients diagnoses with at least one heart related diagnosis during the period 2008--2010. The study shows that the method indeed is able to detect combinations of drugs that occur more frequently for patients with cardiovascular diseases than for patients in a control group, providing opportunities for finding candidate drugs that cause adverse drug effects through interaction.

    Identifying Factors for the Effectiveness of Treatment of Heart Failure: A Registry Study2016Ingår i: IEEE 29th International Symposiumon Computer-Based Medical Systems: CBMS 2016, IEEE Computer Society, 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    An administrative health register containing health care data for over 2 million patients will be used to search for factors that can affect the treatment of heart failure. In the study, we will measure the effects of employed treatment for various groups of heart failure patients, using different measures of effectiveness. Significant deviations in effectiveness of treatments of the various patient groups will be reported and factors that may help explaining the effect of treatment will be analyzed. Identification of the most important factors that may help explain the observed deviations between the different groups will be derived through generation of predictive models, for which variable importance can be calculated. The findings may affect recommended treatments as well as high-lighting deviations from national guidelines.

    Learning from Swedish Healthcare Data2016Ingår i: Proceedings of the 9th ACM International Conference on PErvasive Technologies Related to Assistive Environments, Association for Computing Machinery (ACM), 2016, 47Konferensbidrag (Refereegranskat)
    Abstract [en]

    We present two ongoing projects aimed at learning from health care records. The first project, DADEL, is focusing on high-performance data mining for detrecting adverse drug events in healthcare, and uses electronic patient records covering seven years of patient record data from the Stockholm region in Sweden. The second project is focusing on heart failure and on understanding the differences in treatment between various groups of patients. It uses a Swedish administrative health register containing health care data for over two million patients.

    Theorizing Animal–Computer Interaction as Machinations2017Ingår i: International journal of human-computer studies, ISSN 1071-5819, E-ISSN 1095-9300, Vol. 98, 135-149 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The increased involvement of animals in digital technology and user-computer research opens up for new possibilities and forms of interaction. It also suggests that the emerging field of Animal–Computer Interaction (ACI) needs to reconsider what should be counted as interaction. The most common already established forms of interaction are direct and dyadic, and limited to domesticated animals such as working dogs and pets. Drawing on an ethnography of the use of mobile proximity sensor cameras in ordinary wild boar hunting we emphasize a more complex, diffuse, and not directly observable form of interaction, which involves wild animals in a technological and naturalistic setting. Investigating human and boar activities related to the use of these cameras in the light of Actor-Network Theory (ANT) and Goffman's notion of strategic interaction reveals a gamelike interaction that is prolonged, networked and heterogeneous, in which members of each species is opposed the other in a mutual assessment acted out through a set of strategies and counter-strategies. We stress the role of theory for the field of ACI and how conceptualizations of interaction can be used to excite the imagination and be generative for design. Seeing interaction as strategies and acknowledging the existence of complex interdependencies could potentially inspire the design of more indirect and non-dyadic interactions where a priori simplifications of design challenges as either human or animal can be avoided.

    Smelling, pulling, and looking: unpacking similarities and differences in dog and human city life2015Ingår i: Proceedings of the 12th International Conference on Advances in Computer Entertainment Technology, Association for Computing Machinery (ACM), 2015, 64Konferensbidrag (Refereegranskat)
    Abstract [en]

    The problem of understanding animals, e.g., what they want and what they are doing, are recurrent matters for the emerging field of animal-computer interaction (ACI). We focus on animals in the city by bridging the field with urban studies and open up for new design opportunities in terms of the possibilities of new digital technology to re-configure animal city life. We present an ethnomethodological video analysis of the negotiations and interactional work between two leashed pugs and a handler walking down a street. We unpack similarities and differences between the two species in terms of their interests and intentions in an urban environment through detailed examination of the moments in the walk when the leash is pulled taut. We show how a strained leash can result from a conflict between the dog’s attentiveness towards other dogs by smelling and looking, and the human’s urge to move along. We propose design directions supporting the dogs’ wants and needs by accessing the handler with information on the dogs’ curiosities in other dogs by visualizing the invisible scent-universe of the dogs and encourage dog-dog interaction.

    Plant-computer interaction, beauty and dissemination2016Ingår i: Proceedings of the Third International Conference on Animal-Computer Interaction, Association for Computing Machinery (ACM), 2016, 5Konferensbidrag (Refereegranskat)
    Abstract [en]

    We inquire into ways of understanding plant interaction through a triangulation of four approaches: a multispecies ethnography of people's ordinary practices and doings in relation to sakura trees during their short blossoming season; readings of theoretical works on human-plant relations and plants' urge to spread; a systematic review of how plants are involved in computing and computer systems; and finally a review study on how cherry blossoms are used in design and architecture. We bring these together and propose to discuss the involvement of florae in computer systems and design items through the lens of understanding plant interaction as temporally extended dissemination and agency to spread. The design intent within Animal-Computer Interaction (ACI) has been to develop systems where non-human species are seen as "users". If such an approach is applied to plants, then we need to frame research in a direction that aims to give us an understanding of what these sorts of users are doing. Since the most successful forms of dissemination are hedonic, we argue that researchers should focus more specifically on system design that supports aesthetic interaction, rather than supporting abstract contemplation, as has been common within Human-Computer Interaction (HCI).

    A Method for Designing Digital Innovation Contest Measurement Models2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    As contests become more popular means for organizing digital innovation, the need for measuring contest performance increases. The Digital Innovation Contest Measurement-model (DICM-model), which is the basis for this study was designed based on a single case study, and its evaluation indicated that there is a need for a customizable methodological approach that can accommodate differences in organizational requirements for designing and refining DICM-models. Therefore, in this paper, we present a summary of the evaluation of the DICM-model and propose a nine-step method to design and refine DICM-models using a quality oriented approach. The proposed method is based on the Goal-Question-Metric and the Balanced Scorecard to elicit measures and to enable agility in measuring the fulfilment of measurement goals of innovation contests. Also, the method facilitates knowledge management to refine, record and communicate best practices. An exante evaluation of the method indicates that the method provides practical support in designing and improving a DICM model. For future study, it is suggested to widen the scope of the method to aid in the design of measurement models for digital innovations using open data, in general.

    User Implications for Cloud Based Public Information Systems: A Survey of Swedish Municipalities2015Ingår i: EGOSE 2015, 2015 Conference on Electronic Governance and Open Society: Challenges in Eurasia, Association for Computing Machinery (ACM) , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The emergence of cloud computing has implications for digital service provision in the private and public sector. These implications can introduce opportunities and challenges for user organizations. Evaluation of implications by prioritization and reduction of variables aids in procurement and adoption of cloud based public information systems. However, so far little research is available to evaluate implications of cloud computing in the public sector. The evaluation of implications is carried out through a survey of Swedish municipalities. Quantitatively summarizing the collected data a list of prioritized implications were obtained. In addition to this through a statistical analysis technique called exploratory factor analysis the number of implications are reduced by grouping them into factors. The result shows that the most significant implications for cloud based public information systems are remote access from anywhere at any time, access to and flexibility to choose between state of the art technologies as well as large dependency on vendor and less customization possibilities. A prioritized list of implications is presented from the perspective of users of cloud based public information systems. Through factor analysis we are able to reduce the number of opportunities to six and challenges to four. For future research we suggest to evaluate implications of cloud based public information systems from suppliers’ perspective.

    Evaluating Open Data Innovation: a Measurement Model for Digital Innovation Contests2015Ingår i: PACIS 2015 proceedings, AIS electronic library , 2015, Vol. paper 204Konferensbidrag (Refereegranskat)
    Abstract [en]

    Digital innovation contests emerge as important intermediaries in open data markets. However the understanding of how contests affect innovation value chains is low and there is a lack of innovation measurement frameworks to support the management of digital innovation contests. Therefore, in this paper we apply design science to design a measurement model for digital innovation contests from the organizer’s perspective that adds to the available knowledge of innovation measurement. We use a recent case of digital innovation contests to motivate the model and discuss its implications on the innovation value chain. The measurement model contributes with new knowledge in the area of open data innovation and provides support for practice in managing innovation through digital innovation contests. For future research we intend to enhance the model to also measure the effects on innovation ecosystems, to operationalize the measures and to evaluate the model in several digital innovation contests as well as to include the perspective of the participants.

    Designing Activity and Creating Experience: On People’s Play in Public places2013Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis deals with the design of play in public places; this can mean both pervasive games and other freer play activities. In these activities (as well as in many other game activities) the same game can spur many different ways to play it, and the same activity can be experienced differently by different players, and even differently on different occasions for the same player. An activity such as playing must be observed as a whole. The surrounding cul- ture, player preconceptions and the emergent mood within the group will affect the experience.

    By analysing previous frameworks, and using own design examples, a three level design framework is developed, functioning as a lens towards understanding the design of playful activities. The framework focuses on the player perspective, offering game design as an invitation and encouragement to engage in certain activities. The framework distinguishes between design at three levels:

    1. Designed construct (e.g. artefacts and rules)
    2. Activity
    3. Experiences

    But it remains to be understood why people engage in the activities that lead to playful experiences. What encourages playful engagement? And why do people want to play one game, and not another?

    This question can be split into two parts:

    • Engagement: starting to be interested in the activity
    • Commitment: actually caring for the experience

    This issue is identified in the thesis, and examples show how convoluted this problem is, in particular in pervasive game settings. Challenges are pre- sented for future work.

    The Challenges of Designing a Gender-Aware Pervasive Game2012Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    This paper describes our approach to designing a pervasive game with teenage girls as its main audience. In doing so, we are faced with two challenges: the challenge of gender-aware game design, and the challenge of integrating a pervasive game into the everyday lives of young women. In this paper, we describe our core design goals and the rationale for these goals. Based on these goals, we outline the core design elements, and how these were appreciated by a young women audience in a first player workshop.

    Abstract [en]

    Gender-aware design is important in computer games in general, and perhaps even more so in the design of pervasive games, as these are played in the ordinary world. As pervasive games blur the distinction between game and non-game situations, they influence the everyday lives of their players.

    We discuss the design process for the game 'Codename Heroes' from a gender-aware perspective. The focus is on how players reacted to the experience of playing the game during a sequence of design workshops. We found that playing the game made people less sensitive to 'fear of the outside'. The participants were aware they ‘should’ feel unsafe in unknown neighbourhoods, but mostly did not. Furthermore, a combination of collaboration with internal competition fostered a sense of empowerment. Finally, we could confirm what previous researchers have seen, that women participants tended to blame themselves, rather than the technology or the situation, for errors.

    Development Process Knowledge Transfer through Method Adaptation, Implementation, and Use2004Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Information Systems Engineering (ISE) is an interdisciplinary approach to enable the realisation of successful information systems in a broad sense. ISE comprises a number of areas of expertise that must be integrated and managed in order to build information systems. Since ISE is becoming progressively more complex there is an increasing need to codify and manage knowledge within and about the ISE process.

    From a knowledge perspective the different model types created in an ISE project are examples of codified knowledge about the future system. The descriptions of how work should proceed are examples of codified knowledge of the process of creating the system. In summary, one of the main concerns in the ISE process is to manage the substantial amount of knowledge associated with the process as such as well as with the target domain of the actual development project and the developed software.

    In the thesis I recognise three areas of knowledge in ISE: development process knowledge, target domain knowledge, and software knowledge. Furthermore, I use a set of knowledge perspectives in order to describe and analyse ISE from a knowledge perspective. Finally, I introduce three aspects: organisation, artefact, and individual in order to be able to discuss and analyse how methods are actually used in organisations and how they affect the work situation.

    The results are presented in the form of a framework for knowledge transfer in ISE that comprises the knowledge perspective, the knowledge area, and the aspect of knowledge transfer. The framework is thus used to analyse the results from the six papers enclosed in the thesis. The results also comprise an empirical characterisation of a method in use which is based on data collected during an ethnographical study. Finally the results are made concrete in the form of a pattern collection for method introduction and method use.

    Exploring feedback practices in formative assessment in Rwandan higher education: a multifaceted approach is needed2016Ingår i: International Journal of Teaching and Education, ISSN 1993-3916, Vol. IV, nr 2, 1-22 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Inspired by the current scholarship that indicates that, if used well, formative assessment and feedback can advance student’s learning, this paper explores the practices of feedback in formative assessment in Rwandan higher education, specifically at the University of Rwanda. The study used aqualitative approach with the aim of gaining lecturers’ and students’ perspectives on formative assessment and feedback; and exploring different ways formative assessment and feedback were practiced. Using data collected through interviews, student focus group discussions, and document analysis; the paper shows that formative assessment and feedback were understood in the context of binding prescription within the boundaries of limited description in academic regulations. Feedback was in most cases reduced to marks, and lecturers – who portrayed themselves as information providers, mastery checkers, and performance appraisers - were in full charge of all formative assessment efforts. The paper also shows that lack of clarity and feed forward instructionsin too-much-delayed lecturers’ written feedback led students to just receive feedback and not use it to enhance their performance. Building on this study’s findings and on the existing literature, the paper suggests three important moves whereby a collaborative research-based approach that will bring together different stakeholders will help to move away from a single-sided approach to a multifaceted approach in both perception and practice of formative assessment and feedback at the University of Rwanda.

    A Holistic Approach for Managing ICT Security in Non-Commercial Organisations: A Case Study in a Developing Country2007Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The research reported here is about improvement of the ICT security management process in non-commercial organisations in order to reduce possible financial damage, taking into consideration the realities found in developing countries. The research took place in a developing country—Tanzania, where five organisations were involved.

    The study is organised into seven papers covering: the state of ICT security management in the organisations; prerequisites when utilising the existing ICT security management approaches in attaining a solution for managing ICT security in the organisations; issues and challenges of managing ICT security; important aspects to be taken into consideration in order to successfully manage ICT security; and how the management of ICT security in non-commercial organisations could be improved. Among others, the research was motivated by the observed need for bridging the perception gap between the management and technicians when dealing with the ICT security problem, and consequently extending to a common understanding by the staff in the various departments and specialities within and between the departments.

    The thesis contributes to increased empirical knowledge on the importance of the holistic ICT security management process. Particularly, our main contribution is the proposed holistic approach for managing ICT security in non-commercial organisations, organised in the form of guidelines with two main phases: the initialisation phase which involved the introduction of the ICT security management process in the organisation; and the internalised and continuous phase.

    Abstract [en]

    In this chapter, we discuss state of the art and future perspective of the study of norms with simulative methodologies, in particular employing agent-based simulation. After presenting the state of the art and framing the simulative research on norms in a norm life-cycle schema, we list those research challenges that we feel more apt to be tackled by the simulative approach. We conclude the chapter with the indications for the realization of a NorMAS simulation platform, illustrated by selected scenarios.

    Television on the Internet: New Practices, New Viewers2009Ingår i: International Conference on Human Factors in Computing Systems, ACM , 2009Konferensbidrag (Refereegranskat)
    Abstract [en]

    Television is increasingly viewed through computers in the form of downloaded or steamed content, yet computer based television consumption has received little attention in HCI. In this paper we describe a study of the uses and practices of tech-savvy college students, studying their television consumption through the internet. We find that users personalize their viewing but that TV is still a richly social experience - not as communal watching, but instead through communication around television programs. We explore new possibilities for technology-based interaction around television.

    The Mismeasurement of Privacy: Using Contextual Integrity to Reconsider Privacy in HCI2012Ingår i: CHI '12: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, New York: Association for Computing Machinery (ACM), 2012, 367-376 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Privacy is a widely studied concept in relation to social computing and sensor-based technologies; scores of research papers have investigated people’s ‘privacy preferences’ and apparent reluctance to share personal data. In this paper we explore how Ubicomp and HCI studies have approached the notion of privacy, often as a quantifiable concept. Leaning on several theoretical frameworks, but in particular Nissenbaum’s notion of contextual integrity, we question the viability of obtaining universal answers in terms of people’s ‘general’ privacy practices and apply elements of Nissenbaum’s theory to our own data in order to illustrate its relevance. We then suggest restructuring inquiries into information sharing in studies of state-of-the-art technologies and analyze contextually grounded issues using a different, more specific vocabulary. Finally, we provide the first building blocks to such vocabulary.

    The Sociality of Fieldwork: Designing for Social Science Research Practice and Collaboration2012Ingår i: PROCEEDINGS OF THE 17TH ACM INTERNATIONAL CONFERENCE ON SUPPORTING GROUP WORK, Association for Computing Machinery (ACM), 2012, 35-44 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Supporting scientific practice has been a longstanding goal of CSCW research. This paper explores how we might design for social science research practices and collaboration. Drawing on sixteen interviews with fieldwork-based social scientists we document the importance of small-scale long-term collaborative arrangements for research and intellectual work - pairs of researchers who work together in-depth over their careers, developing a common yet distinctive view of their research field. This contrasts with the large-scale short-lived collaborations that have classically been the target of cyber-infrastructure work. We describe technology practices among social scientists and how these can inform technology design for fieldwork practices.

    Unpacking the television: User practices around a changing technology2009Ingår i: Transactions n Computer-Human Interaction, Vol. 16Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article investigates the changing television watching practices amongst early adopters of personal hard-disk video recorders (such as Tivo) and Internet downloading of video. Through in- depth interviews with 21 video enthusiasts, we describe how the rhythms of television watching change when decoupled from broadcast TV schedules. Devices such as Tivo do not simply replace videotapes; TV watching becomes more active as programs are gathered from the schedules, played from a stored collection and fast forwarded and paused during playback. Downloads users exploit the Internet to view shows and movies not broadcast, yet this watching is not fundamentally different from recording shows using a PVR, since both involve selection of shows from a limited range and a wait before the shows can be watched.

    Engaging the Periphery for Visual Communication on Mobile Phones2010Ingår i: Hawaii International Conference on System Sciences, IEEE , 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    While mobile phones have become ubiquitous instruments of communication and social interaction, they still require explicit interaction, placing high demands on attention. Engaging the periphery of users’ attention offers opportunities for awareness and interaction while reducing demands on attention and risks of disruption. We explore the mobile peripheral design space with Emotipix, an application for camera phones that turns the background of the phone’s display into a place for visual conversations. We conducted an exploratory 2-week user study with 6 pairs and one 4- person group, and found that Emotipix facilitated ongoing social practices. Our study shows that there is an unexploited opportunity to use mobile phones for peripheral awareness. We provide recommendations for managing users’ expectations, desires for control, and privacy in mobile peripheral display design.

    Watching the footwork: second screen interaction at a dance and music performance2014Ingår i: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, New York: Association for Computing Machinery (ACM), 2014, 1305-1314 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Interactive mobile technologies have become part of audience experiences of live performances in terms of both general media sharing and specific (sometimes official) extra content. At the same time, high bandwidth affords streaming of live events to mobile devices. We take advantage of these technologies in our high resolution, panoramic image video stream and study a scenario of audience members viewing the very same live event they are watching on a tablet. The video stream on the tablet is navigational and enables audience members to pan and zoom in the real-time video feed. We studied audience interaction and impressions in three performances of a dance and music show and found distinct uses of the second screen video stream. We emphasize that despite initial reluctance, the observed utilization of the technology opened up for new potential practices. Our study shows how working with perceived conflict in technology can still open up design space for interactive technologies.

    Empowerment through seamfulness: Smart phones in everyday life2010Ingår i: Personal and Ubiquitous Computing, Vol. 15Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this paper, we describe research into use of multifunctional mobile phones by working adults and posit the device as a plausible realization of ubiquitous com- puting. We investigate how users actively adapt and adopt the different functions in smart phones to suit their needs and lifestyles. Through an interview and diary study, we discover how the smart phone is used in pragmatic and seamful ways, regardless of the interface of the specific phone selected or the particular features available. Users used phones in highly individual manners; mixed and adapted existing functions to meet their own priorities; added some functions and ignored others to create their own portfolio; and blended their use with the specifics of their everyday lives. While these data challenge some assumptions of human–computer interaction and ubiqui- tous computing, it also presents new research potential in terms of understanding how users take advantage of the multiple features in smart phone devices and how they utilize seamfulness in everyday smart phones practices.

    Acting with Technology: Rehearsing for Mixed-Media Live Performances2016Ingår i: CHI '16 Proceedings of the 2016 CHI Conference on Human Factors in Computing Systems, Association for Computing Machinery (ACM), 2016, 864-875 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Digital technologies provide theater with new possibilities for combining traditional stage-based performances with interactive artifacts, for streaming remote parallel performances and for other device facilitated audience interaction. Compared to traditional theater, mixed-media performances require a different type of engagement from the actors and rehearsing is challenging, as it can be impossible to rehearse with all the functional technology and interaction. Here, we report experiences from a case study of two mixed-media performances; we studied the rehearsal practices of two actors who were performing in two different plays. We describe how the actors practiced presence during rehearsal in a play where they would be geographically remote, and we describe the challenges of rehearsing with several remote and interactive elements. Our study informs the broader aims of interactive and mixed media performances through addressing critical factors of implementing technology into rehearsal practices.

    In this position paper we present our ongoing research in relation to cultivating democracy and civic participation through the writing and performance of interactive theater experiences1. We provide an example of a performance that facilitates audience participation through expression and sharing of opinions and emotions, by means of digital technologies. The performance leads to further discussion within the community and inspires more artistic and theatrical experiences in this context.

    Social networking on the go: Students' socialization in the age of Facebook2010Ingår i: International conference on Human factors in computing systems (CHI), ACM , 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    Most research regarding online social networks such as Facebook, MySpace, Linked-In and Friendster has looked at these networks in terms of activity within the online network, such as profile management and friending behavior. In this paper we are instead focusing on offline socializing structures around an online social network (exemplified by Facebook) and how this can facilitate in- person social life for students. Because students lead nomadic lives, they find Facebook a particularly useful tool for initiating and managing social gatherings, and as they adopt mobile technologies that can access online social networks, their ad-hoc social life is further enabled. We conclude that online social networks are a powerful tool for encouraging peripheral friendships, important in particular to students. We emphasize that the use of online social networks must be viewed from a perspective of use that involves both mobile and stationary platforms and that it is important to relate online and offline social practices.

    New interaction modes for rich panoramic live video experiences2014Ingår i: Behavior and Information Technology, ISSN 0144-929X, E-ISSN 1362-3001, Vol. 33, nr 8, 859-869 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The possibilities of panoramic video are based on the capabilities of high-resolution digital video streams and higher bandwidth's opportunities to broadcast, stream and transfer large content across platforms. With these opportunities also come challenges such as how to focus on sub-parts of the video stream and interact with the content shown on a large screen. In this paper, we present studies of two different interaction modes with a large-scale panoramic video for live experiences; we focus on interactional challenges and explore if it is (1) possible to develop new interactional methods/ways of approaching this type of high-resolution content and (2) feasible for users to interact with the content in these new ways. We developed prototypes for two different interaction modes: an individual system on a mobile device, either a tablet or a mobile phone, for interacting with the content on the same and a non-touch gesture-based system for the home or small group interaction. We present pilot studies where we explore the possibilities and challenges with these two interaction modes for panoramic content.

    Impediments to Effective Management of Project Interdependencies: A Study of IT/IS Project Portfolios2017Ingår i: Journal of Electronic Commerce in Organizations, ISSN 1539-2937, E-ISSN 1539-2929, Vol. 15, nr 2, 16-30 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Interdependencies between projects have come to play a more active role in the decision on IT/IS portfolios and their constituent projects. However, managing these interdependencies can be a complex task, especially when the number and degree of interdependencies among projects are high. In times of uncertainty, unexpected challenges can seriously disrupt projects and, consequently, their interdependencies. This may threaten the project portfolio from achieving its final goal. The study aims to investigate the difficulties associated with managing project interdependence along the development cycle of the project portfolio. The study was conducted using a qualitative approach and semi-structured interviews with managers from four leading organizations in Saudi Arabia. The findings reveal three main categories of factors that increased the difficulty of managing project interdependencies in large IT/IS project portfolios: insufficient understanding of human responsibilities in the whole portfolio, unpredictability of the environment, and technology barriers and constraints.

    INVESTIGATING THE SOURCES OF DIFFICULTIES IN MANAGING PROJECT INTERDEPENDENCIES: A STUDY OF IT/IS PROJECT PORTFOLIOS2016Ingår i: PROCEEDINGS OF THE 9th IADIS INTERNATIONAL CONFERENCE INFORMATION SYSTEMS 2016 / [ed] Miguel Baptista Nunes, Pedro Isaías, Philip Powell, IADIS Press, 2016, 71-82 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Interdependencies between projects can take a major role in IT/IS project portfolios. However, managing these interdependencies can be a difficult task, especially when the number and diversity of projects grow large in scale. In times of unexpected events, extra management efforts are inevitable for treating the subsequent effects on the projects and their interdependencies, and for maintaining high-performance portfolios. Complexity is also a concern for managers, and a growing complexity level may threatens the project portfolio from achieving its final goal. This paper investigates the managerial issues and difficulties in handling project interdependencies. For a closer look at these interdependencies and to gain more understanding of the problem area, a qualitative study was conducted based on semi-structured interviews with managers from four leading organizations in different industries in Saudi Arabia. The findings reveal three main sources of difficulty in managing project interdependencies in IT/IS project portfolios: 1) Insufficient understanding of human responsibilities in the whole portfolio, 2) Environmental change and 3) Technological constraints.

    Abstract [en]

    Adequately managing project interdependencies among diverse and simultaneous projects is deemed critical for successful implementation of project portfolios. The challenge is significant because it may entail managing a complex network of project interdependencies that keeps changing over time. The present study investigates the managerial challenges that may undermine effective management of project interdependencies in IT/IS project portfolios. The investigation is based on evidence from reviewing relevant literature and documented studies associated with managing project interdependencies. The main contribution of this study is to discuss three managerial challenges of project interdependencies in project portfolios. We discuss the challenges from three perspectives: types of interdependencies; patterns of interaction in interdependencies; and cost/benefit impact of project interdependencies.

    Project interdependency management in IT/IS project portfolios: from a systems perspective2016Ingår i: Procedia Computer Science, ISSN 1877-0509, E-ISSN 1877-0509, Vol. 100, 928-934 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Capitalizing on inter-project interdependencies is widely accepted as being crucial for Information Technology/Information Systems (IT/IS) project portfolio success. However, handling these interdependencies becomes a source of increased management complexity as project portfolios get larger, increasingly diverse, and are much influenced by their environments. This then can lead to less predictable situations regarding the portfolio performance as a whole. Though there are many methods available for optimally selecting projects and cross-checking possible synergies and interdependencies among the projects in the portfolio, it remains unclear how one can gain control over the complexity of managing these interdependencies. In this study, we address the problem of handling many project interdependencies that continuously change and develop within a large IT/IS project portfolio. We found that the existing methods for selecting and managing the projects within a portfolio do not focus enough on how interdependencies can disrupt the balance of the whole project portfolio system. To tackle the problem, we propose a systemic approach using the Viable System Model to enhance the way that these interdependencies can be effectively managed in view of the overall portfolio system. We suggest that the Viable System Model, as a supplement to traditional IT/IS project portfolio management approaches, is recursively applied to diagnose and manage the complexity of project interdependencies within IT/IS project portfolios.

    How Was Your Day?: Evaluating a Conversational Companion2013Ingår i: IEEE Transactions on Affective Computing, ISSN 1949-3045, Vol. 4, nr 3, 299-311 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The How Was Your Day(HWYD) companion is an embodied conversational agent that can discuss work-related issues, entering free-form dialogues while discussing issues surrounding a typical work day. The open-ended nature of these interactions requires new models of evaluation. Here, we describe a paradigm and methodology for evaluating the main aspects of such functionality in conjunction with overall system behavior, with respect to three parameters: functional ability (i.e., does it do the rightthing conversationally), content (i.e., does it respond appropriately to the semantic context), and emotional behavior (i.e., given the emotional input from the user, does it respond in an emotionally appropriate way). We demonstrate the functionality of our evaluation paradigm as a method for both grading current system performance, and targeting areas for particular performance review. We show correlation between, for example, automatic speech recognition performance and overall system performance (as is expected in systems of this type), but beyond this, we show where individual utterances or responses, indicated as positive or negative, characterize system performance, and demonstrate how our combination evaluation approach highlights issues (both positive and negative) in the companion system's interaction behavior.

    Abstraction, Restriction, and Co-creation: Three Perspectives on Services2010Ingår i: Advances in Conceptual Modeling – Applications and Challenges, Berlin: Springer Verlag , 2010, 107-116 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    The recent surge in the interest of services has brought a plethora of applications of the service concept. There are business services and software services, software-as-a-service, platform-as-a-service, and infrastructure-as-a-service. There is also a multitude of definitions of the service concept. In this paper, we propose not a new definition of service but a conceptual model of the service concept that views services as perspectives on the use and offering of resources. The perspectives addressed by the model are: service as a means for abstraction; service as means for providing restricted access to resources; and service as a means for co-creation of value.

    Towards a Model of Services Based on Cocreation, Abstraction and Rights Distribution2015Ingår i: Correct Software in Web Applications and Web Services / [ed] Bernhard Thalheim, Klaus-Dieter Schewe, Andreas Prinz, Bruno Buchberger, Cham: Springer, 2015, 29-44 s.Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    The term service is today defined and used in a multitude of ways, which are often ambiguous and contradictory. The absence of a commonly agreed-upon definition of the term makes it difficult to distinguish, describe and classify services. In order to address these issues, this chapter proposes a model of services that helps in analysing the concept. The model encompasses three perspectives: service as a means for cocreation of value, service as a means for abstraction and service as a means for distributing rights. The model does not suggest a definition of the term service but shows how the service concept can be analysed using a number of related concepts, like service resource, service process and service offering. The model has its theoretical foundation in the Resource-Event-Agent (REA) ontology and Hohfeld’s classification of rights.
