    Middleware’s message : the financial technics of codata

    In this paper, I will argue for the relevance of certain distinctive features of messaging systems, namely those in which data (a) can be sent and received asynchronously, (b) can be sent to multiple simultaneous recipients and (c) is received as a “potentially infinite” flow of unpredictable events. I will describe the social technology of the stock ticker, a telegraphic device introduced at the New York Stock Exchange in the 1860s, with reference to early twentieth century philosophers of synchronous experience (Bergson), simultaneous sign interpretations (Mead and Peirce), and flows of discrete events (Bachelard). Then, I will show how the ticker’s data flows developed into the 1990s-era technologies of message queues and message brokers, which distinguished themselves through their asynchronous implementation of ticker-like message feeds sent between otherwise incompatible computers and terminals. These latter systems’ characteristic “publish/subscribe” communication pattern was one in which conceptually centralized (if logically distributed) flows of messages would be “published,” and for which “subscribers” would be spontaneously notified when events of interest occurred. This paradigm—common to the so-called “message-oriented middleware” systems of the late 1990s—would re-emerge in different asynchronous distributed system contexts over the following decades, from “push media” to Twitter to the Internet of Things

    A study of the portability of an Ada system in the software engineering laboratory (SEL)

    Get PDF
    A particular porting effort is discussed, and various statistics on analyzing the portability of Ada and the total staff months (overall and by phase) required to accomplish the rehost, are given. This effort is compared to past experiments on the rehosting of FORTRAN systems. The discussion includes an analysis of the types of errors encountered during the rehosting, the changes required to rehost the system, experiences with the Alsys IBM Ada compiler, the impediments encountered, and the lessons learned during this study

    Patterns of technological progress and corporate innovation

    Get PDF
    The bulk of the global innovative effort takes place in 5 countries: USA, Japan and China as leaders, with France and United Kingdom as immediate followers, which all display, on the long run, a negative marginal value added on innovation. The present paper attempts to answer the following question: why does most of innovative activity takes place in markets apparently hostile to innovation, i.e. giving back negative marginal value added on innovation ? A model is introduced in which any market may be represented as a Selten’s extensive game, subgames of which are played as Harsanyi’s games with imperfect information, by a temporarily finite and changing set of players. The firms’ innovative activity is a Nash’s dynamic equilibrium in which innovating is rational though suboptimal, without premium on innovation being a real economic profit. The model is the theoretical framework for the study of six cases: Ford Motor, General Motors, Honda, Chevron, Akzo Nobel and IBM, which allow to conclude that firms do innovation either because they have to or because this is their comparative advantage and they can do it in an exceptionally efficient way. As economic growth is grounded in efficient business patterns and in some countries those business patterns shape themselves in the context of a strong exogenous pressure on innovation. This leads to the development of economies which, regardless its pace of economic growth and balance of payments, come to a point when marginal value added on innovation is negative. At this point, however, incentives to innovate do not disappear and firms continue to apply the same business patterns and thus do create scientific input which gives back negative marginal real output. This pattern of global technological progress seem to be quite durable, with financial markets that allow to compensate, by successful financial placements, the downturns of innovative projects.innovation; technology; technological progress; corporate strategies

    Phases of Cost Cutting: Downsizing is Dead; Long Live the Downsizing Phenomenon

    Get PDF
    This downsizing research article presents a phase typology of job cutting which includes three distinct phases and three levels of argument. Conceptually, the paper draws heavily upon the seminal work of Littler and Gandolfi (2008) seeking to expand and update their 2008 Academy of Management (AOM) Conference paper. The paper culminates with a contemporary discussion of current downsizing practices showcasing that the strategy of downsizing has remained a popular restructuring method on a global scale.downsizing; cost cutting; phase; strategy.

    Organisational change and the computerisation of British and Spanish savings banks, 1965-1985

    Get PDF
    In this article we explore organisational changes associated with the automation of financial intermediaries in Spain and the UK. This international comparison looks at the evolution of the same organisational form in two distinct competitive environments. Changes in regulation and technological developments (particularly applications of information technology) are said to be responsible for enhancing competitiveness of retail finance. Archival research on the evolution of savings banks helps to ascertain how, prior to competitive changes taking place, participants in bank markets had to develop capabilities to compete
