    Bounds on spectral condition numbers of matrices arising in the $p$ -version of the finite element method (1995)

    Notes: Summary. We estimate condition numbers of $p$ -version matrices for tensor product elements with two choices of reference element degrees of freedom. In one case (Lagrange elements) the condition numbers grow exponentially in $p$ , whereas in the other (hierarchical basis functions based on Tchebycheff polynomials) the condition numbers grow rapidly but only algebraically in $p$ . We conjecture that regardless of the choice of basis the condition numbers grow like $p^{4d}$ or faster, where $d$ is the dimension of the spatial domain.

    Webmasters as mass media gatekeepers: a qualitative exploratory study (1999)
    Bingley : Emerald
    Internet research 9 (1999), S. 200-211 
    Details
    ISSN: 1066-2243
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Computer Science
    Notes: Eight college and university Webmasters in three midwestern states were interviewed to explore their communications practices and activities by applying a traditional mass media gatekeeping perspective. The results suggest that gatekeeping theory is a valuable approach for studying individuals responsible for the mediation of messages in the emerging online media. Webmasters' personal characteristics and attitudes were found to influence their media content decisions, they share common values used to determine content and design, and they face a variety of organizational and related constraints, some exclusive to Web gatekeepers in an academic setting. Examples of gatekeeping activity and observations by the informants are presented, and suggestions for future research are included.

    Aspects of a systemic philosophy of knowledge: from social facts to data, information and knowledge (2002)
    Bingley : Emerald

    Notes: Considers from a cybernetic point of view, a number of philosophical problems raised by the design and utilization of information systems and knowledge management. Discusses the transformation from facts in social systems, via data and information into knowledge, and the practical use of knowledge, which is defined as the cybernetic strategy of action. This paper is normative and conceptual and the research question posed is: How are social facts transformed into data, data into information, and information into knowledge?

    Systemic thinking as the philosophical foundation for knowledge management and organizational learning (1999)
    Bingley : Emerald
    Kybernetes 28 (1999), S. 24-46 
    Details
    ISSN: 0368-492X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Computer Science
    Notes: In this article we will discuss the link between systemic thinking, organizational learning and knowledge management. We will develop a conceptual model to illustrate and explain this link, which will be further discussed throughout the article. The main entities of this model are: emphasis on internal motivation, relations in and among systems, in addition to the development of vision, generation of ideas and creativity. The philosophical basis for this model is systemic thinking. We will thus explain the meaning of this way of thinking, before we discuss the individual elements of the conceptual model.

    Strategic use of information technology for increased innovation and performance (1999)

    Notes: Although we observe a general optimism concerning IT's potential for creating suitable competitive advantages, there exists a lack of empirical support for the positive economic impact of IT on businesses. This is denoted as the productivity paradox of IT. We argue that in situations of hypercompetition, using conventional productivity measures as the only performance indicator would be inadequate when studying the impact IT has. Furthermore, investing in IT does not ensure its proper implementation. Consequently there is a need to consider what companies are using IT for and its consequences for innovation and a variety of performance measures. In a study of 200 firms within the Norwegian IT sector, we found that focusing on the use of IT might be a promising route for studying the relationship between IT and successful innovations, and between IT and performance. We also found a number of trade-offs between the various performance measures and between successful innovations and performance. Although we were able to find positive effects of IT we argue in favour of developing an information and a knowledge strategy prior to developing an IT strategy

    A mathematical model for fibro-proliferative wound healing disorders (1996)
    Springer
    Bulletin of mathematical biology 58 (1996), S. 787-808

    Notes: Abstract The normal process of dermal wound healing fails in some cases, due to fibro-proliferative disorders such as keloid and hypertrophic scars. These types of abnormal healing may be regarded as pathologically excessive responses to wounding in terms of fibroblastic cell profiles and their inflammatory growth-factor mediators. Biologically, these conditions are poorly understood and current medical treatments are thus unreliable. In this paper, the authors apply an existing deterministic mathematical model for fibroplasia and wound contraction in adult mammalian dermis (Olsenet al., J. theor. Biol. 177, 113–128, 1995) to investigate key clinical problems concerning these healing disorders. A caricature model is proposed which retains the fundamental cellular and chemical components of the full model, in order to analyse the spatiotemporal dynamics of the initiation, progression, cessation and regression of fibro-contractive diseases in relation to normal healing. This model accounts for fibroblastic cell migration, proliferation and death and growth-factor diffusion, production by cells and tissue removal/decay. Explicit results are obtained in terms of the model processes and parameters. The rate of cellular production of the chemical is shown to be critical to the development of a stable pathological state. Further, cessation and/or regression of the disease depend on appropriate spatiotemporally varying forms for this production rate, which can be understood in terms of the bistability of the normal dermal and pathological steady states—a central property of the model, which is evident from stability and bifurcation analyses. The work predicts novel, biologically realistic and testable pathogenic and control mechanisms, the understanding of which will lead toward more effective strategies for clinical therapy of fibro-proliferative disorders.

    Greenhouse gas abatement — toward Pareto-optimal decisions under uncertainty (1996)
    Springer
    Annals of operations research 68 (1996), S. 267-279 
    Details
    ISSN: 1572-9338
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics , Economics
    Notes: Abstract This paper examines the economic logic of integrated assessment — balancing the costs against the benefits of greenhouse gas abatement. “Stylized facts” are employed in a multiregion computable general equilibrium model with a public good. The percentage shares of global emissions are determined outside the model — based upon some form of international agreement — and emission rights are tradeable between regions. The analysis is confined to Pareto-optimal (cooperative) solutions. We focus on the sensitivity of initial decisions to low-probability, high-consequence scenarios associated with cumulative emissions. For simplicity, there are only two regions, two tradeable goods, two time periods, and two states-of-world. With the particular form of public good model adopted here (production rather than utility function impacts), it turns out that a Pareto-optimal hedging strategy is indepedent of the emission shares allocated to each region. Equity issues may be separated from those of economic efficiency. Similar results extend to cases in which there are additional regions, tradeable goods, time periods, and states-of-world.
