This article, which offers a critical reassessment of the underlying rationale for universal service policies, argues that public policies designed to promote universal telecommunications access are simply a form of wealth redistribution. By reconceptualizing universal service subsidies in this way, one can obtain a more realistic assessment of the proper scope and limits of universal service policies. Universal service policies, at best, can play a supplementary role. Economic reforms that encourage investment and promote robust competition are more fundamental to the development of an ubiquitous infrastructure than government subsidies. The redistribution of wealth via telecommunications can ameliorate inequalities, but it cannot eliminate their causes, and advocates should stop pretending that it can. Furthermore, universal service advocates must become more aware of the political and economic risks and pitfalls that are inherent in the process of wealth redistribution. 相似文献

This article explores the vulnerability of publicly held broadcasting companies to hostile takeovers. It finds that such companies are more attractive to investors than typical corporations, but that broadcasters are better defended against unfriendly takeovers and not especially vulnerable to takeovers. 相似文献

With the presence of online, digital content and new services for manipulating and searching it, printing and publishing firms may experience technological uncertainty and risk and diminishing profitability. Mergers and acquisitions are approaches for dealing with the current technology and market changes that are underway in the printing and publishing industry. Using an event study methodology and a sample of 60 U.S. printing and publishing firms, this study investigates the value creation of acquiring information technology (IT) services firms. The study's findings reveal that printing and publishing firms experience significant increases in their market values as a result of acquiring IT services firms. In fact, non-newspaper firms realize the largest increases in market value. The study's findings should help academicians and practitioners understand the kinds of strategic acquisitions from which printing and publishing firms are most likely to benefit. 相似文献

In America’s state houses small yet powerful collections of policy leaders, in the public and private sector, are guiding the initial conception and early implementation of advanced communication networks. This article investigates how the beliefs of leading actors collide to produce two distinctive state networks. Rather than focus exclusively on the simple dichotomous “yes” or “no” decision regarding the adoption or nonadoption of an advanced telecommunications system, like a statewide information highway, this article focuses on the critical role of debate imbedded within that decision. Analysis and presentation of interviews and extensive literature reviews of the development of information highways, in North Carolina and Iowa, provide the setting for the generation of hypotheses suggesting the future trajectory of technology policymaking. While praised for their bold, visionary leadership and innovative system designs, the accounts of network development in these two American states also provide a cautionary tale for other subnational governments and for private sector telecommunications firms interested in the business of building public sector information highways. 相似文献

Although there has been much research into corporate governance generally, little attention has been focused specifically on issues in media companies. The question is further complicated by the increasing frequency with which media enterprises that have traditionally operated within the industrial context of a specific medium are becoming business lines for media conglomerates and must compete for resources and strategic attention from a board more concerned with bottom-line profitability than with traditional media industry norms. This study examines board compositions of 21 firms with leadership positions in 1 or more traditional mass media industries and compares governance structure and results for those firms that are concentrated in 1 media segment to those that operate multiple media segments. Relations between skills sets associated with different categories of board members (legal, finance, consumer/marketing, service, academic, and other), management influence, and other board demographics to the creation of shareholder value were identified based on financial measures of market value, earnings per share, and dividend levels. The relations between board characteristics and strategic measures of capital reinvestment, asset sales, and acquisitions were also examined. A number of significant differences were identified between single-industry and conglomerate firms in these dimensions. 相似文献

This article places universal service policy in telecommunications in Australia in an historical context. Given the dynamic growth in information technologies, universal service should be reconceptualized within a knowledge-based discourse critically linked to considerations for deepening participatory democracy. As a consequence of the discussion this article recommends that funding universal service obligations in telecommunications be based on the preferred notion of a maximally open democratic debate. The universal service obligation in telecommunications should be funded from consolidated revenue with its parameters set by democratic debate. 相似文献

This paper reports on the development of a realistic knowledge-based application using the MOBAL system. Some problems and requirements resulting from industrial-caliber tasks are formulated. A step-by-step account of the construction of a knowledge base for such a task demonstrates how the interleaved use of several learning algorithms in concert with an inference engine and a graphical interface can fulfill those requirements. Design, analysis, revision, refinement and extension of a working model are combined in one incremental process. This illustrates the balanced cooperative modelling approach. The case study is taken from the telecommunications domain and more precisely deals with security management in telecommunications networks. MOBAL would be used as part of a security management tool for acquiring, validating and refining a security policy. The modeling approach is compared with other approaches, such as KADS and stand-alone machine learning. 相似文献

The field of telecommunications is at a historic crossroads in its evolution and development. The combination of a rapidly changing global economy coupled with advancements in new media and telecommunications technology are having a profound effect on higher education and those academic disciplines that specialize in media management, telecommunications, and management of information systems. This article is about change and what we as educators are doing to prepare our students for the future world of work. Special attention is given to the challenges and opportunities that face the telecommunications discipline itself. Tomorrow's telecommunications professionals will have to be trained using a far more innovative approach to curriculum design than was the case in past years. The long-term success of any academic program will ultimately depend on the proper blending of its core strengths with a view toward the future in terms of innovative curriculum design. 相似文献

This article focuses on the rapid technological changes in telecommunications, and how these advances are affecting the Malaysian broadcasting industry, a relatively mature industry that is compelled to innovate or become destabilized. It traces the growth and development of broadcasting and telecommunications, and discusses the implications of the privatization policy on the changing industry and for the country. 相似文献

This article proposes a methodology for studying the social history of telecommunications grounded in the interrelations and contaminations between Anglophone and Continental literature; its originality lies in the fact that it presents and discusses both traditions. Before tackling the central theme, the reasons for studying the history of telecommunications will be discussed and three different approaches will be considered. The first is the constructivist approach which, examines ‘relevant social groups’ and their decisions regarding telecommunications. The second is socio-economic and considers both path dependence theories and concepts useful in understanding the network economy: natural monopolies, economies of scale, externalities and public services. Finally, the macro-systemic approach will be considered. In our proposal these three approaches, deriving from both the Anglophone and Continental schools of thought, form a methodological basis for studying the history of telecommunications. 相似文献

New regulatory institution for the convergence of broadcasting and telecommunications: A Korean case
Daeho Kim Author Vitae 《Government Information Quarterly》2011,28(2):155-163
This paper addresses a new case for the convergent regulatory institution for broadcasting and telecommunications in Korea. This paper emphasizes that, when considering a convergent regulatory body, Korea's main principle to establish is a reflection of the paradigm shift of convergence and IT industry. The proposal of the Korean Communications Commission addresses that as a prior factor. This paper deals with three characteristics in establishing the KCC: accommodating policy making and regulation together within a single institution; choosing a commission model as a new organizational type, which inherits a broadcasting legacy to ensure diversity and independence; combining content and network sector together. This paper attempts to show that the Korean model gives a power to the convergent regulatory institution to make the country remain one of the leading countries in information and communication sector as well as implement convergence of broadcasting and telecommunications successfully. 相似文献

Effective delivery of biomedical information to health professionals depends on the availability of systems that are compatible with the information-seeking patterns of health professionals. MEDLINE is a major source of biomedical information, but has been available primarily through libraries via telecommunications networks. The recent availability of MEDLINE on CD-ROM has made it possible to provide MEDLINE directly to clinicians without the associated problems of telecommunications and online use charges. The MEDLINE on CD-ROM Evaluation Forum sponsored by the National Library of Medicine reported on clinicians' use of CD-ROM MEDLINE at seven different clinical settings. This article summarizes the findings from these sites and places them in the context of current understanding of information-seeking behaviors of health professionals. Key issues in the design and development of information technologies in the clinical setting are also articulated. 相似文献

The end of the Second World War saw global telecommunications governance renegotiated. The dominant British Imperial (later Commonwealth) network experienced multiple changes: the tightly integrated and collaborative imperial governance system fell away as the governing partners increasingly pursued their own, rather than a collective agendas and as the ‘imperial’ company, Cable and Wireless', dominance gave way to a competition and interconnection based regime as American firms and their networks entered markets hitherto closed to them. Though key elements of the Bermuda Telecommunications Agreement 1945 were soon to be renegotiated, the Bermuda Conference, at which the imperial partners and the new hegemonic power, the USA, bargained, was the fulcrum transitional event. Drawing on archival sources (notably in Canada and the UK) the author tells of the tensions within the fragmenting Imperial partnership, of an American mix of interest and idealism and of this episode in telecommunications liberalisation foreshadowing later changes. 相似文献

Any notion of cancelling very expensive American and European science journals in order to subscribe to Japanese titles is shown to be questionable. Analysis of the published output of several firms and universities, sampling from dozens of journals, and examination of thousands of articles and citations suggest that with a few exceptions, the Japanese themselves place primary emphasis on appearing in these same, very expensive, highly cited American and European titles. While the Japanese do have journals well worth acquiring, their acquisition must be funded by other means. 相似文献

This article offers an analytical overview of pathbreaking U.S. telecommunications reform legislation, as a concrete first step in establishing new industry and regulatory paradigms for telecommunications. It describes key elements of the Act, contrasting them to the status quo ante, in the areas of competition, concentration, and the public interest. It concludes that, while the Act responds to economic, political and technological paradigm shifts, it continues to assert a prominent role for the state in articulating policy, and leaves open an important role for civil society in defining and implementing it terms. 相似文献

The relatively new topic of Next Generation Networks (NGN) is one which is ascending rapidly communications policy agendas in Europe and beyond. How these networks might be created and, beyond that, how they might function in a sustained and broadly useful manner, and the implications of this, are issues which crystallise a raft of often complex policy concerns that have emerged, for at least a decade, in historically distant though increasingly connected quarters of electronic network communications. This article breaks new ground in the analysis of the emerging role of the EU by exploring EU NGN policy from a convergence infrastructural and content perspective. Whilst at this stage, despite new ‘policy packaging’, the EU's NGN policy activity is resonant of past telecommunications and audiovisual policies, the article contends that there are key areas where the EU can exercise considerable policy leverage through utilising a combination of formal legal and soft governance capacities. This has a greater chance of materialising how the more transnational NGN networks and services become. 相似文献

In the context of its role in providing the day-to-day administration of the European Union, the European Commission is responsible both for stimulating the development of interactive electronic information services in Europe and for providing public online databases of information on the Union's activities. Following a brief survey of the background to the Commission's activities, this article outlines the Union's current telecommunications policy and the ongoing transition towards closer integration of the various telecommunications networks in Europe. It then describes the various practical arrangements for obtaining access to the Commission's online services, presents two of its programmes, which are intended to stimulate the professional use of electronic information services, and lists the various databases that it provides for public access. 相似文献
