Over the last 35 years, centralized universal-number (in the United States, 9-1-1) systems have come to be the preferred means of emergency-response dispatching. The creation of these systems has motivated the development of information systems that render the landscape, to those with the right access, increasingly legible. This has been to the benefit of those receiving emergency services, but also to the benefit of police and commercial interests, who have used the improved infrastructure as bases for the creation of geodemographic and other profiling systems. More recently, the creation of wireless telephony has motivated the creation of a further surveillance infrastructure built on and integrated into that landscape. One consequence has been the commercialization of the systems in ways that permit the incorporation of more intimate and detailed data into preexisting systems. Public concern with locational surveillance systems has focused on privacy. However, “privacy” may be an inadequate frame through which to understand these issues and to fashion appropriate responses. 相似文献

This paper summarizes the pilot stage of a microeconomic study of the innovation performance through time of young, high-technology Israeli firms. It reports some results for a successful firm designing, producing and selling electronic instruments and systems. The paper begins by surveying some of the difficulties surrounding the collection and organization of data on R&D projects. One of them concerns the definition of the ‘Unit for Analysis’ - the R&D project. Three criteria are suggested for dividing the stream for innovative activities into R&D projects, and these are applied to group the tens of products, accessories and systems included in the analysis into nine projects. The paper subsequently defines a measure of “direct” project performance or profitability estimate - discounted operating profits per unit of fixed costs - and provides estimates based on R&D and sales data for the products of each project. The final sections analyze the variation of project profitability through time. The increasing profitability observed across generations of a product class is attributed to the adaptability of the firm to changes in the environment, particularly to the availability of new technology which requires the swift design and sale of more complex products. The qualitative history of the various projects suggests that this adaptability is due, to a large extent, to the skills, infrastructure and reputation of the firm accumulated from prior projects, i.e. that the “indirect” profitability of the latter is high. Some estimates of the indirect profitability of early projects are presented. A comparison of the spin-off mechanisms observed in the firm analyzed with those observed in firms of other industries is also undertaken. 相似文献

Researchers in indexing and retrieval systems have been advocating the inclusion of more contextual information to improve results. The proliferation of full-text databases and advances in computer storage capacity have made it possible to carry out text analysis by means of linguistic and extra-linguistic knowledge. Since the mid 80s, research has tended to pay more attention to context, giving discourse analysis a more central role. The research presented in this paper aims to check whether discourse variables have an impact on modern information retrieval and classification algorithms. In order to evaluate this hypothesis, a functional framework for information analysis in an automated environment has been proposed, where the n-grams (filtering) and the k-means and Chen’s classification algorithms have been tested against sub-collections of documents based on the following discourse variables: “Genre”, “Register”, “Domain terminology”, and “Document structure”. The results obtained with the algorithms for the different sub-collections were compared to the MeSH information structure. These demonstrate that n-grams does not appear to have a clear dependence on discourse variables, though the k-means classification algorithm does, but only on domain terminology and document structure, and finally Chen’s algorithm has a clear dependence on all of the discourse variables. This information could be used to design better classification algorithms, where discourse variables should be taken into account. Other minor conclusions drawn from these results are also presented. 相似文献

This study looks at the perceived ability of components of IT infrastructure integration and supply chain process integration to predict specific radio frequency identification (RFID) system deployment outcomes—exploration, exploitation, operational efficiency, and market knowledge creation. Data for this pilot research study was collected using a survey questionnaire administered online to members of the Council of Supply Chain Management Professionals (CSCMP). It was hypothesized that data consistency and cross-functional application integration, both elements constituting IT infrastructure integration, and information flow integration, physical flow integration, and financial flow integration, all elements constituting supply chain process integration would be positively associated with and predict the four RFID system outcomes. Multiple regression results show partial support for all four proposed hypotheses. Cross-functional application integration and financial flow integration predicted exploration, while data consistency and physical flow integration predicted exploitation. Data consistency and cross-functional application integration, on the other hand, predicted both operational efficiency and market knowledge creation. Supply chain managers planning to deploy RFID systems are alerted to the criticality of these IT infrastructure issues as they brace for a likely widespread implementation of RFID in supply chains they participate in. 相似文献

Over the past two decades, both developed and developing countries have been investing a significant portion of their resources in the creation of an information infrastructure. However, speculation abounds regarding the efficacy of information infrastructure investments, especially when the opportunity cost for investing in information technology (IT) is measurably high among developing nations. This longitudinal study introduces and explores infrastructure development and service-sector growth as key metrics for IT investment success. It also traces the notional evidence of IT infrastructure development as mediating the causal relationship between information infrastructure investments and service-sector growth. Using data from low-income, middle-income, and high-income countries, the mediating and lagged impact of information infrastructure on service-sector growth reveals that information infrastructure development does play a significant role as a mediator. It points out that information infrastructure investments can be a misleading causal antecedent if countries fail to develop their infrastructure. It also provides evidence of a recursive relationship between infrastructure development and service-sector growth. An exploratory time-series analysis across different country categories suggests that information infrastructures must be properly developed to reconcile the paradox. In addition, exploratory tests reveal a distinct divergence between infrastructure investments and infrastructure development among different country tiers. 相似文献

Even though knowledge assets have been widely recognized as the principal drivers of firm's competitive advantage, few are the frameworks that have explained how these strategic assets are transformed into value and how the value creation process occurs. Also there is a confusing terminology in the literature surrounding many concepts explaining the dynamics of value creation. By conducting a Systematic Review – an evidence-based methodology for theory building – this paper seeks to define a ‘common language’ of the concepts used to explain this phenomenon, and build the assumptions of a theoretical model that explains how knowledge assets, through learning mechanisms, are linked, renewed, and leveraged into socio-technical processes or organizational routines, that in turn form the basis of organizational capabilities. As they are socially constructed, these organizational capabilities, when leveraged into products and services, generate value and provide firms with a sustainable competitive advantage and long-term superior performance. The model should therefore serve as a theoretical contribution to the literature and it has a further potential benefit to begin an inquiry, for both theory building and management, about the nature of firm's knowledge assets and organizational capabilities, and the sources of sustainable competitive advantage. Some of these avenues are outlined in this paper. 相似文献

This paper describes the experience gained in the Center for Technological Innovation since its creation three years ago within the National Autonomous University of Mexico. By offering the services of locating clients, drafting and negotiating contracts, providing specialized information services, and project follow-up, the Center pursues the establishment of effective ties between University projects and industrial production. In so doing, its staff informally assumes the critical “dgate-keeper” and “entrepreneur” roles, not easily accepted in other areas of the University.The main difficulties encountered so far have been in developing interdisciplinary projects, providing due academic recognition for technological activities and extending knowledge about innovation throughout the University. On the other hand, a great advantage is the interest shown by the academic community; likewise is UNAM's stability and autonomy, structural characteristics which have stimulated the development of technically sound teams over several decades. To date, the Center has provided support services for 125 projects and has participated in establishing 44 contracts between the University and industry. 相似文献

Infrastructure threatens to lock-in societies to fossil fuels unless something is done now. This is because infrastructure lasts for such a long time, meaning that any infrastructure built or rebuilt now will last well into the twenty-first century – until the end of the century, in some cases. Consequently, there is a need to integrate climate change into infrastructure now or societies will be left with infrastructure designed around unsustainable socio-technical systems (such as combustion engines, roads, and suburbanization). Such change is conceptualized in the literature as a sustainability transition. However, any attempts at such transitions have to address the ‘materialities’ of infrastructure systems (physical form, environmental context, and so on). In this paper, I develop the concept of ‘socio-material systems’ and apply it to transport infrastructure in Ontario, Canada. 相似文献

Artificial Life (ALife) has two goals. One attempts to describe fundamental qualities of living systems through agent based
computer models. And the second studies whether or not we can artificially create living things in computational mediums that
can be realized either, virtually in software, or through biotechnology. The study of ALife has recently branched into two
further subdivisions, one is “dry” ALife, which is the study of living systems “in silico” through the use of computer simulations,
and the other is “wet” ALife that uses biological material to realize what has only been simulated on computers, effectively
wet ALife uses biological material as a kind of computer. This is challenging to the field of computer ethics as it points
towards a future in which computer and bioethics might have shared concerns. The emerging studies into wet ALife are likely
to provide strong empirical evidence for ALife’s most challenging hypothesis: that life is a certain set of computable functions
that can be duplicated in any medium. I believe this will propel ALife into the midst of the mother of all cultural battles
that has been gathering around the emergence of biotechnology. Philosophers need to pay close attention to this debate and
can serve a vital role in clarifying and resolving the dispute. But even if ALife is merely a computer modeling technique
that sheds light on living systems, it still has a number of significant ethical implications such as its use in the modeling
of moral and ethical systems, as well as in the creation of artificial moral agents. 相似文献

Trust between transaction partners in cyberspace has come to be considered a distinct possibility. In this article the focus is on the conditions for its creation by way of assuming, not inferring trust. After a survey of its development over the years (in the writings of authors like Luhmann, Baier, Gambetta, and Pettit), this mechanism of trust is explored in a study of personal journal blogs. After a brief presentation of some technicalities of blogging and authors’ motives for writing their diaries, I try to answer the question, ‘Why do the overwhelming majority of web diarists dare to expose the intimate details of their lives to the world at large?’ It is argued that the mechanism of assuming trust is at play: authors simply assume that future visitors to their blog will be sympathetic readers, worthy of their intimacies. This assumption then may create a self-fulfilling cycle of mutual admiration. Thereupon, this phenomenon of blogging about one’s intimacies is linked to Calvert’s theory of ‘mediated voyeurism’ and Mathiesen’s notion of ‘synopticism’. It is to be interpreted as a form of ‘empowering exhibitionism’ that reaffirms subjectivity. Various types of ‘synopticon’ are distinguished, each drawing the line between public and private differently. In the most ‘radical’ synopticon blogging proceeds in total transparency and the concept of privacy is declared obsolete; the societal gaze of surveillance is proudly returned and nullified. Finally it is shown that, in practice, these conceptions of blogging are put to a severe test, while authors often have to cope with known people from ‘real life’ complaining, and with ‘trolling’ strangers. 相似文献

在文献回顾的基础上,本研究提出了社会资本和竞争优势之间关系的假设模型,并通过对浙江省72家中小企业的问卷调查验证这一模型。研究结果表明:中小企业社会资本对知识共享与创造具有显著的正向影响;中小企业社会资本不仅直接影响智力资本,还通过知识共享与创造间接影响企业智力资本;智力资本在知识共享与创造和竞争优势之间起到了完全中介作用;中小企业社会资本不仅直接影响竞争优势,同时还通过知识共享与创造和智力资本间接地影响竞争优势。研究认为,中小企业要确立竞争优势,必须重视社会资本、智力资本的投入,同时还要营造有利于知识共享与创造的企业氛围。 相似文献

Recent advances in wireless technologies have led to the development of intelligent, in-vehicle safety applications designed
to share information about the actions of nearby vehicles, potential road hazards, and ultimately predict dangerous scenarios
or imminent collisions. These vehicle safety communication (VSC) technologies rely on the creation of autonomous, self-organizing,
wireless communication networks connecting vehicles with roadside infrastructure and with each other. As the technical standards
and communication protocols for VSC technologies are still being developed, certain ethical implications of these new information
technologies emerge: Coupled with the predicted safety benefits of VSC applications is a potential rise in the ability to
surveil a driver engaging in her everyday activities on the public roads. This paper will explore how the introduction of
VSC technologies might disrupt the “contextual integrity” of personal information flows in the context of highway travel and
threaten one’s “privacy in public.” Since VSC technologies and their related protocols and standards are still in the developmental
stage, the paper will conclude by revealing how close attention to the ethical implications of the remaining design decisions
can inform and guide designers of VSC technologies to create innovate safety applications that increase public safety, but
without compromising the value of one’s privacy in public.
