    Concepts from Coevolution in Information Systems

    This paper provides an overview of definitions and concepts from coevolution that may be useful in the domain of information systems (IS). Both the management literature and the information systems literature are reviewed to highlight insights that have been drawn from coevolution. Aspects of coevolution that have been considered important in the literature include the dynamic, emergent nature and the mutli-levelness of coevolutionary processes. The nature of the coevolutionary relationship has not received as much attention. This paper presents a classification scheme drawn from Thompson (2005) that can be used to explore the nature of coevolutionary interactions in more depth. It is suggested that future IS research applying a coevolutionary framework can be enhanced with a deeper consideration of the nature of the interactions and with the incorporation of theories from the social sciences

    This bibliography lists 259 reports, articles, and other documents introduced into the NASA scientific and technical information system between July 1, 1980 and December 31, 1980. Its purpose is to provide information to the researcher, manager, and designer in technology development and mission design in the area of the Large Space Systems Technology Program. Subject matter is grouped according to systems, interactive analysis and design. Structural concepts, control systems, electronics, advanced materials, assembly concepts, propulsion, solar power satellite systems, and flight experiments

    Mind your step! : How profiling location reveals your identity - and how you prepare for it

    Get PDF
    Location-based services (LBS) are services that position your mobile phone to provide some context-based service for you. Some of these services – called ‘location tracking’ applications - need frequent updates of the current position to decide whether a service should be initiated. Thus, internet-based systems will continuously collect and process the location in relationship to a personal context of an identified customer. This paper will present the concept of location as part of a person’s identity. I will conceptualize location in information systems and relate it to concepts like privacy, geographical information systems and surveillance. The talk will present how the knowledge of a person's private life and identity can be enhanced with data mining technologies on location profiles and movement patterns. Finally, some first concepts about protecting location information

    Changes in information systems projects –important concepts

    Project management plays a key role in leveraging project success in organizations. However, regardless of the quality of management, it is normal that changes occur during the development of information technology and information systems projects, which are almost inevitable. These changes may relate, for example, to the requirements, the cost of resources, the time available for carrying out the activities, the loss of human resources, among many others. Thus, it is essential to analyze the impact of these changes before they are accommodated in the project so that the success of the project is not affected. This article presents a review of key concepts on project changes, including the causes, types, and impacts of changes.A gestão de projetos desempenha um papel fundamental no que respeita ao potenciar do sucesso dos projetos nas organizações. Contudo, independentemente da qualidade da gestão, é normal que surjam alterações ao longo do desenvolvimento dos projetos de tecnologias e sistemas de informação, as quais são praticamente inevitáveis. Essas alterações podem ser, por exemplo, relativas aos requisitos, ao custo dos recursos, ao tempo disponível para a realização das atividades, à perda de recursos humanos, entre muitas outras. Assim, torna-se importante analisar o impacto dessas alterações antes de serem acomodadasno projeto, de modo a que o sucesso do mesmo não seja afetado.

    A Framework of Information Systems Development Concepts

    Get PDF
    Background: Information Systems Development (ISD) is responsible for designing and implementing information systems that support organizational strategy, leveraging business models and processes. Several perspectives on this activity can be found in the literature, addressing – often in an undifferentiated manner – approaches, lifecycles, methodologies, and process models, among others. Objectives: The vast diversity of ideas and concepts surrounding ISD and the multiple underlying views on the subject make it harder for researchers and practitioners to understand the relevant aspects of this important activity. This article aims to systematize and organize ISD’s main concepts to create a coherent perspective. Methods/Approach: We conducted a literature review and thematic analysis of ISD\u27s main concepts. Results: To contribute to filling the research gap, this article proposes a new framework that addresses the key aspects related to ISD. Conclusions: The framework comprises ISD’s core concepts, such as lifecycles, process models, deployment approaches, and methodologies

    A national health information strategy for Malta

    Get PDF
    In 1992 a national health information strategy was developed jointly by the Department of Health and the Information Systems Division. A detailed strategy study report was compiled, with recommendations for the development of a number of information systems. The main system proposed was an integrated and comprehensive health care information system encompassing all of Malta’s hospitals and health centres, based on a single Patient Master Index. This system would support the concepts of an integrated health record and of a person-based view for resource management.peer-reviewe

    Division of labour and sharing of knowledge for synchronous collaborative information retrieval

    Get PDF
    Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques
