    The communications sector of an economy comprises a range of technologies, physical media, and institutions/rules that facilitate the storage of information through means other than a society\u27s oral tradition and the transmission of that information over distances beyond the normal reach of human conversation. This chapter provides data on the historical evolution of a disparate range of industries and institutions contributing to the movement and storage of information in the United States over the past two centuries. These include the U.S. Postal Service, the newspaper industry, book publishing, the telegraph, wired and cellular telephone service, radio and television, and the Internet

    Panel III:  Implications of the New Telecommunications Legislation

    We present a method that employs a tree-based Neural Network (NN) for performing classification. The novel mechanism, apart from incorporating the information provided by unlabeled and labeled instances, re-arranges the nodes of the tree as per the laws of Adaptive Data Structures (ADSs). Particularly, we investigate the Pattern Recognition (PR) capabilities of the Tree-Based Topology-Oriented SOM (TTOSOM) when Conditional Rotations (CONROT) [8] are incorporated into the learning scheme. The learning methodology inherits all the properties of the TTOSOM-based classifier designed in [4]. However, we now augment it with the property that frequently accessed nodes are moved closer to the root of the tree. Our experimental results show that on average, the classification capabilities of our proposed strategy are reasonably comparable to those obtained by some of the state-of-the-art classification schemes that only use labeled instances during the training phase. The experiments also show that improved levels of accuracy can be obtained by imposing trees with a larger number of nodes

    Reinventing Media Activism: Public Interest Advocacy in the Making of U.S. Communication-Information Policy, 1960-2002

    Get PDF
    This report is a long-term analysis of citizens' collective action to influence public policy toward communication and information. The work discusses in greater detail what is meant by communication and information policy (CIP) and why we think it is worthwhile to study it as a distinctive domain of public policy and citizen action. The report concentrates on citizen action in the United States and looks backwards, tracing the long-term evolutionary trajectory of communications-information advocacy in the USA since the 1960s. We focus on the concept of citizen collective action and explain its relevance to CIP.Research supported by the Ford Foundation's Knowledge, Creativity and Freedom Program.

    Technological Convergence: a Strategic Perspective

    Get PDF
    The information and communication technologies (ICT) sectors are in a process of technological convergence. Determinant factors in this process are the liberalisation of the telecommunications markets and technological change. Many firms are engaged in a process of mergers and alliances to position themselves in this new framework. Technological and demand uncertainties are very important. Our objective in this paper is to study the economic determinants of the strategies of the firms. With this aim, we review some key technological and demand aspects. We shed some light on the strategic motivations of the firms by establishing a parallel with the evolution of the retailing sector.Technological Convergence; Demand Uncertainty; technological Uncertainty; Technology Life Cycle; Internet; Multimedia; Strategy

    Telecommunications 2004: Business Strategy, HR Practices, and Performance

    This national benchmarking report of the U.S. telecommunications services industry traces the tumultuous changes in management and workforce practices and performance in the sector over the last 5 years. This is a follow-up report to our 1998 study. At that time, when the industry was booming, we conducted a national survey of establishments in the industry. In 2003, we returned to do a second national survey of the industry, this time in a sector that was recovering from one of the worst recessions in its history

    The Political Economy of Cable - "Open Access."

    Get PDF
    Advocates of "open access" claim that Internet Service Providers (ISPs) should be able to use a cable TV system's bandwidth on the same terms offered to ISPs owned by the cable system. On that view, "open access" mitigates a monopoly bottleneck and encourages the growth of broadband. This paper shows that cable operators do enjoy market power, and do seek to leverage a dominant position in video into the broadband access market by allocating too little bandwidth for Internet access. Yet, rather than protect cable operators from cannibalizing their cable TV revenue, this strategy defends against imposition of common carrier regulation, which would allow system capacity to be appropriated by regulators and rival broadband networks. Ironically, the push for "open access" limits Internet access by encouraging this under-allocation of broadband spectrum, and by introducing coordination problems slowing technology deployment. These effects are empirically evident in the competitive superiority of cable's "closed" platform vis-a-vis "open" DSL networks, and in financial market reactions to key regulatory events and mergers in broadband.
