    Wikileaks and the limits of protocol

    Get PDF
    In this chapter, I reflect on Wikileaks and its use of technology to achieve freedom in capitalist society. Wikileaks represents an avant-garde form of media (i.e. networked, cryptographic), with traditional democratic values: opposing power and seeking the truth. At times, http://wikileaks.org appears broken and half abandoned and at other times, it is clearly operating beyond the level of government efficiency and military intelligence. It has received both high acclaim and severe criticism from human rights organisations, the mainstream media and governments. It is a really existing threat to traditional forms of power and control yet, I suggest, it is fundamentally restrained by liberal ideology of freedom and democracy and the protocological limits of cybernetic capitalism

    Building fault detection data to aid diagnostic algorithm creation and performance testing.

    It is estimated that approximately 4-5% of national energy consumption can be saved through corrections to existing commercial building controls infrastructure and resulting improvements to efficiency. Correspondingly, automated fault detection and diagnostics (FDD) algorithms are designed to identify the presence of operational faults and their root causes. A diversity of techniques is used for FDD spanning physical models, black box, and rule-based approaches. A persistent challenge has been the lack of common datasets and test methods to benchmark their performance accuracy. This article presents a first of its kind public dataset with ground-truth data on the presence and absence of building faults. This dataset spans a range of seasons and operational conditions and encompasses multiple building system types. It contains information on fault severity, as well as data points reflective of the measurements in building control systems that FDD algorithms typically have access to. The data were created using simulation models as well as experimental test facilities, and will be expanded over time

    The Quest for Appropriate Remedies in the Microsoft Antitrust EU Cases: A Comparative Appraisal

    Get PDF
    The Microsoft cases in the United States and in Europe have been influential in determining the contours of the substantive liability standards for dominant firms in US antitrust law and in EC Competition law. The competition law remedies that were adopted, following the finding of liability, seem, however, to constitute the main measure for the “success” of the case(s). An important disagreement exists between those arguing that the remedies put in place failed to address the roots of the competition law violation identified in the liability decision and others who advance the view that the remedies were far-reaching and that their alleged failure demonstrates the weakness of the liability claim. This study evaluates these claims by examining the variety of remedies that were finally imposed in the European Microsoft cases, from a comparative perspective. The study begins with a discussion of the roots of the Microsoft issues in Europe and the consequent choice of a remedial approach by the Commission and the Court. It then explores the effectiveness of the remedies in achieving the aims that were set. The non-consideration of the structural remedy in the European case and the pros and cons of developing such a remedy in the future are briefly discussed before more emphasis is put on alternative remedies (competition and non-competition law ones) that have been suggested in the literature. The study concludes by discussing the fit between the remedy and the theory of consumer harm that led to the finding of liability and questions a total dissociation between the two. We believe that it is important to think seriously about potential remedies before litigation begins. However, we do not require an ex ante identification of an appropriate remedy by the plaintiffs, since this could lead to underenforcement or overenforcement.antitrust, remedies, Microsoft, complementarity, innovation, efficiency, monopoly, oligopoly, media player, interoperability, Internet browser

    Understanding Behavioral Sources of Process Variation Following Enterprise System Deployment

    Get PDF
    This paper extends the current understanding of the time-sensitivity of intent and usage following large-scale IT implementation. Our study focuses on perceived system misfit with organizational processes in tandem with the availability of system circumvention opportunities. Case study comparisons and controlled experiments are used to support the theoretical unpacking of organizational and technical contingencies and their relationship to shifts in user intentions and variation in work-processing tactics over time. Findings suggest that managers and users may retain strong intentions to circumvent systems in the presence of perceived task-technology misfit. The perceived ease with which this circumvention is attainable factors significantly into the timeframe within which it is attempted, and subsequently impacts the onset of deviation from prescribed practice and anticipated dynamics

    Agent-Based Computational Modeling And Macroeconomics

    Get PDF
    Agent-based Computational Economics (ACE) is the computational study of economic processes modeled as dynamic systems of interacting agents. This essay discusses the potential use of ACE modeling tools for the study of macroeconomic systems. Points are illustrated using an ACE model of a two-sector decentralized market economy.

    Testing the Reliability of FERC's Wholesale Power Market Platform: An Agent-Based Computational Economics Approach

    Get PDF
    In April 2003 the U.S. Federal Energy Regulatory Commission (FERC) proposed the Wholesale Power Market Platform (WPMP) for common adoption by U.S. wholesale power markets. The WPMP is a complicated market design that has been adopted in some regions of the U.S. but resisted in others on the grounds that its reliability has not yet been sufficiently tested. This article reports on the development of an agent-based computational framework for exploring the economic reliability of the WPMP. The key issue under study is the extent to which the WPMP is capable of sustaining efficient, orderly, and fair market outcomes over time despite attempts by market participants to gain advantage through strategic pricing, capacity withholding, and/or induced transmission congestion.
