This paper reviews 20 years of information economics in Prometheus. It finds broad coherence about the theme of information as knowledge‐capital, as distinct from information as a message in a market‐space. The paper suggests that micro‐foundations for the Prometheus school of information economics should be based in evolutionary micro‐economic theory rather than in neoclassical micro‐economic theory.  相似文献

Science policy, as the theme appears in Prometheus over the last 20 years, has been represented by discussions of industrial competitiveness. Many comparative articles have appeared under this theme, as well as evaluations of policies aimed at innovation. By the mid‐1980s, articles in Prometheus were tracing the emergence of the knowledge economy, with some of its associated issues. The issue of human resources for the knowledge economy has received scant attention, however, but Prometheus authors have discussed public participation in science policymaking and setting priorities. Finally, authors have noted and analyzed the closer management of Australian science to direct it toward economic ends. Overall, Prometheus has tracked the dominant themes of science policy in other OECD countries well, and also given space to issues that are less prominent but nonetheless important.  相似文献

This paper reviews the contribution that Prometheus has made over the past 20 years to the literature on innovation, innovation policy and technological change. I offer first a necessarily subjective view of how the research literatures of innovation and innovation policy have developed in recent decades. I then compare that account with an interpretation of the emphases and trends in the corresponding areas in Prometheus. The research literatures involved are vast, located in many specific discipline areas and cross many discipline boundaries. While my ‘home’ discipline is economics I believe much can still be learned from the flexible and imaginative use of economics to frame research inquiry in the innovation area.  相似文献

In this article I review 20 years of writing on communication policy in Prometheus. I examine the contribution Prometheus has made to three areas of knowledge about communication policy: communication itself, its histories, and broad notions of communication policy; telecommunications; and new communication technology. I suggest that it is in the latter two areas focusing on the technological dimensions of communication policy, that the journal has consistently contributed genuinely innovative work. Here the journal has fostered interdisciplinary writing and enquiry where policy and technology developments most required critique and new ideas.  相似文献

This is a review of Hans Moravec's book, Robot: Mere Machine to Transcendent Mind. This review raises three categories of questions relating to Moravec's vision of the future. First, there are the ethical and social implications issues implicit in robotics research. Second, there are the soul issues, which especially relate to the prospect of the demoralization of human beings. Third, there is the issue as to whether a robot could ever be a sentient being.  相似文献

Recent anthropological analyses of Chinese attitudes towards privacy fail to pay adequate attention to more ordinary, but more widely shared ideas of privacy – ideas that, moreover, have changed dramatically since the 1980s as China has become more and more open to Western countries, cultures, and their network and computing technologies. I begin by reviewing these changes, in part to show how contemporary notions of privacy in China constitute a dialectical synthesis of both traditional Chinese emphases on the importance of the family and the state and more Western emphases on individual rights, including the right to privacy. This same synthesis can be seen in contemporary Chinese law and scholarship regarding privacy. A review of recent work in philosophical ethics demonstrates that information ethics in China is in its very early stages. In this work, privacy is justified as an instrumental good, rather than an intrinsic good. I argue by way of conclusion that privacy protections will continue to expand in China, in part under the pressures of globalization, increasing trade with and exposure to Western societies, and the increasing demands for Western-style individual privacy by young people. Even so, I argue that these emerging conceptions of privacy will remain distinctively Chinese – i.e., they will retain a basic consistency with traditional Chinese values and approaches.  相似文献

This essay is a critique of LarryLessig's book, Code and other Laws ofCyberspace (Basic Books, 1999). Itsummarizes Lessig's theory of the fourmodalities of regulation in cyberspace: code,law, markets, and norms. It applies thistheory to the topics of privacy and speech,illustrating how code can undermine basicrights or liberties. The review raisesquestions about the role of ethics in thismodel, and it argues that ethical principlesmust be given a privileged position in anytheory that purports to deal with the shapingof behavior in cyberspace. Finally, itproposes a philosophy of ethicalself-regulation instead of an over-reliance ongovernment policy to deal with certainimproprieties and negative externalities thattend to disrupt the Net.  相似文献

This article challenges the desirability of implementing more than the minimum patent standards required by Australia’s commitment to the World Trade Organisation’s Agreement on Trade Related Aspects of Intellectual Property Rights (so‐called ‘TRIPs‐plus’ measures). We argue that there has not been an adequate analysis of what the various TRIPs‐plus measures actually are under the Patents Act 1990 (Cth), and that these measures have not been subjected to a competition analysis as required by the Competition Principles Agreement. This is, we contend, reminiscent of ‘cargo cult’ as Australian policy makers appear to reason that the most developed nations have benefited from innovation with TRIPs‐plus measures, and so with similar measures, those same benefits will accrue to Australia.  相似文献

Optimal loan periods   总被引:1,自引:0,他引:1  
The influence of a library's loan period on user satisfaction is a topic of considerable current interest. In this paper a model is created that is useful for studying this interaction. A policy, possibly appropriate for a reserve book room, is assumed, in which no queues form. Users not able to take out a book either give up or return. Also, the model includes the effect of a patron not being able to use a book for a sufficient length of time. This model yields equations for the value of the loan period that minimizes the number of transactions at the circulation desk consistent with a constant level of real demand. An iterative solution procedure is described and its convergence proven. Other objective functions, and in particular, the probability of a user successfully using a book, are considered.The objective of the paper is not to detail an operating procedure for circulation systems, but to continue the discussion initiated by Philip Morse about how such systems can be modelled. Morse introduces a queuing model for circulating books, but neglects to consider the impact of queue formation on the arrival rate to the system. The intention of this paper is to emphasize the necessity of introducing such considerations and to indicate how such complications can be analytically treated. The specific system modelled is a simplified one, similar to the one discussed by Bruce in a recent article published in L.Q. This model, or variants adapted to local conditions should be useful in assisting decision-making regarding circulation, but it is the modelling process rather than the management aspect that is addressed by this paper.  相似文献

Many existing systems for analyzing and summarizing customer reviews about products or service are based on a number of prominent review aspects. Conventionally, the prominent review aspects of a product type are determined manually. This costly approach cannot scale to large and cross-domain services such as Amazon.com, Taobao.com or Yelp.com where there are a large number of product types and new products emerge almost everyday. In this paper, we propose a novel method empowered by knowledge sources such as Probase and WordNet, for extracting the most prominent aspects of a given product type from textual reviews. The proposed method, ExtRA (Extraction of Prominent Review Aspects), (i) extracts the aspect candidates from text reviews based on a data-driven approach, (ii) builds an aspect graph utilizing the Probase to narrow the aspect space, (iii) separates the space into reasonable aspect clusters by employing a set ofproposed algorithms and finally (iv) generates K most prominent aspect terms or phrases which do not overlap semantically automatically without supervision from those aspect clusters. ExtRA extracts high-quality prominent aspects as well as aspect clusters with little semantic overlap by exploring knowledge sources. ExtRA can extract not only words but also phrases as prominent aspects. Furthermore, it is general-purpose and can be applied to almost any type of product and service. Extensive experiments show that ExtRA is effective and achieves the state-of-the-art performance on a dataset consisting of different product types.  相似文献
