Bridging the digital divide between information and technology haves and have-nots has waned from the top of the national policy agenda in the United States during a time in which the sunken investments of the 1990s need to be leveraged. A national information network now exists yet this infrastructure--largely hardware--needs to be continually modernized and parlayed with commitments to building human capacity, developing relevant content, and scaling socially beneficial technology applications, such as telemedicine, in order to optimize these initial multi-billion-dollar outlays. This article makes the case that sidestepping public-private initiatives aimed at accelerating digital opportunity is imprudent, given the mounting empirical evidence highlighting the payoffs of information and communications technologies, when properly integrated and applied, especially in enhancing the life chances of underserved Americans. Policy next steps should advance the goals of expanding universal service initiatives, including hastening broadband deployment to homes and learning institutions, and deepening programs which leverage the utility of the existing infrastructure, such as expanding human-capital development, producing relevant content, and innovating socially beneficial technology applications. 相似文献

Government, major information and communications technology (ICT) companies, and educational institutions in the United Kingdom currently claim that ICT skills training offers inclusion into the new economy. We focus on a private-public training initiative and its impact on the socially excluded, specifically lone women parents. Narrative data from four United Kingdom educational sites participating in this computer network engineer training program highlight a systemic paradox: that ICT skills development initiatives designed to support lone women parents are simultaneously working in opposition to broader policy goals such as work-life balance and ironically serve to reproduce the participants' classification as socially excluded. The assumptions underpinning the model of social inclusion driving the ICT skills training course are analyzed critically using the concepts of community of practice, classificatory systems, and marginalization. Our findings suggest that ICT training courses and initiatives should be accompanied by changes in pedagogic practice that accommodate the more wide-ranging needs of those targeted for inclusion, as well as changes in employment settings. We conclude by exploring the implications of this for government policy formation, business vendor qualifications, the design of ICT skills training initiatives, and our understanding of the role of ICT skills in overcoming the digital divide. 相似文献

This paper compares the Canadian and Chinese national strategies for digital records by the aspects of the term national, the status of digital records and their management, and the key features of the newly developed strategies of the two countries. By doing so, it aims at revealing best practices and/or lessons learned that are instructive to a wider information community for application and adaptation, irrespective of the existence of certain political and administrative differences. The comparison revealed one similarity that both countries recognize the lack of qualified professionals for discharging the duties of managing digital records, yet a number of distinctions in areas such as records focus, relationships between the development of the strategies and academic input, dedication of records management, and the role of national archives. It concludes that there are areas about which the countries can learn from each other, which applies in particular to Canada. 相似文献

Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction. 相似文献

Cloud computing is a popular outsourcing solution for organizations to support the information management during the life cycle of digital information goods. However, outsourcing management with a public provider results in a lack of control over digital products, which could produce incidents such as data unavailability during service outages, violations of confidentiality and/or legal issues. This paper presents a novel distribution model of digital products inspired by lean supply chain principles called CloudChain, which has been designed to support the information management during digital product lifecycle. This model enables connected networks of customers, partners and organizations to conduct the stages of digital product lifecycle as value chains. Virtual distribution channels are created over cloud resources for applications of organizations to deliver digital products to applications of partners through a seamless information flow. A configurable packing and logistic service was developed to ensure confidentiality and privacy in the product delivery by using encrypted packs. A chain management architecture enables organizations to keep tighter control over their value chains, distribution channels and digital products. CloudChain software instances were integrated to an information management system of a space agency. In an experimental evaluation CloudChain prototype was evaluated in a private cloud where the feasibility of applying supply chain principles to the delivery of digital products in terms of efficiency, flexibility and security was revealed. 相似文献

This article identifies scenarios of technology use in rural libraries to promote community engagement in overcoming marginalization and bridging rural digital divides in the Southern and Central Appalachian (SCA) region. The research is based on a qualitative content analysis of feedback collected from 15 rural librarians in semi-structured interviews and three respondents each in five focus groups during 2017–2018. Select scenarios defined as typical experience-related representative narratives of technology use of rural librarians serve as a tool to investigate their community-engaged initiatives. Respondents’ perspectives, behaviors, and experiences of technology use in community engagement selectively highlight their activities, collaborating partners, encountered challenges specific to the region, and the resulting outcomes of their initiatives. The article extends past theory-practice discourse in information science research to integrate impact that was documented in respondents’ community-engaged technology use behaviors in the SCA rural environments. It explores a positive model of technology use and community engagement in the SCA rural libraries as a strategy to overcome marginalization and bridge rural digital divides historically experienced in the region. 相似文献
