The discrepancy between national information infrastructure capabilities and the present-day requirements of the new economic institutional environment is one of main causes of the gap between the significant volume of fundamental and applied innovation research results that have commercialization potential, and the actual abilities of our domestic industry to assimilate these results, which exists in Russia. The purpose of this article is to form at least a rough conceptual look at an effective information infrastructure for innovation and scientific and technical activities, which corresponds to the present-day requirements of the new economic institutional environment in Russia. To solve the problem of overcoming inertial trends in national information system development, new ideas and new conceptual approaches are required. The presented conceptual approaches are oriented toward solving the problems of modernization and the development of a qualitatively new structural and substantial organization of the national information system. Most of the critical phases of information support of the stages of technology transfer and the basic principles of information infrastructure development are shown. A brief enumeration of the set of key actions on the development of the information infrastructure of the scientific, technical, and industrial spheres is provided.  相似文献

文章将知识分为全隐性知识、半隐性知识、半显性知识和全显性知识,并提出了基于这四类知识的六种知识转化模式,即社会化、自组织化、半显性化、全显性化、整合化和内在化。文章分析了全显性化和整合化两种转化模式的客观性,以及社会化、自组织化、半显性化和内在化四种模式的主观性,并提出组织应通过管理控制来促进客观性知识转化,通过增强组织支持来推动主观性知识转化。  相似文献

The Internet plays a critical role in informing individuals about society, politics, business, and the environment. So much so that it has been said that the digital divide makes the segment of society on the “right side” of the divide (the digitally endowed group) better off and that on the “wrong side” (the digitally challenged group) worse off. This is not always true, however, in a social choice situation where members of a society collectively choose one alternative from a set of alternatives. To identify conditions when this does not hold, a model of the digital divide is setup in which the digitally endowed group receives better information than the digitally challenged group. Preferences of all individuals over outcomes are distributed over a scale. This distribution is correlated with the digital divide: the outcome preferred by the digitally endowed group differs from that preferred by the other group. The alternative chosen by majority becomes the choice of the overall society. The ensuing analysis shows that individuals located centrally on the preference scale are sensitive to information about the state. The choice of centrally located digitally challenged individuals, made on a lack of information, makes the digitally challenged group worse off as has been predicted before. In some cases, the digitally endowed group is worse off as well. In the case of highly polar alternatives, social welfare decreases due to the welfare loss of the digitally endowed group. Results suggest that policymakers must manage the digital divide in a customized manner depending on the preferences context. They should not only focus on improving the welfare of the digitally challenged, but also focus on the welfare of the digitally endowed group so that this welfare does not decrease.  相似文献

The traditional focus of intergovernmental services research has been on technological development, not on user acceptance; yet user acceptance of intergovernmental services in each electronic government (e-Government) implementation affects the ultimate success of the e-Government project. In the e-Government implementation context, many governments have invested huge amounts of money and manpower to make intergovernmental services both available and user-accepted, although some individuals have no intention of using them. The electronic document management system (EDMS) is the most popular intergovernmental service in the e-Government project. Thus, e-Government researchers need to identify the factors that determine user acceptance of EDMS.  相似文献

The goal of this research is to address the effectiveness of Neighborhood Information Systems (NIS) as an Information Technology (IT) tool in assisting community development. NISs are hybrid applications of Geographical Information Systems (GIS) and web technologies that provide demographic, social, and economic information to community stakeholders. Government agencies, nonprofit organizations, and community organizations engage in decision-making process for community development, and NISs are designed to help information-sharing and effective and participatory decision-makings for community development stakeholders.  相似文献

With the help of a team of expert biologist judges, the TREC Genomics track has generated four large sets of “gold standard” test collections, comprised of over a hundred unique topics, two kinds of ad hoc retrieval tasks, and their corresponding relevance judgments. Over the years of the track, increasingly complex tasks necessitated the creation of judging tools and training guidelines to accommodate teams of part-time short-term workers from a variety of specialized biological scientific backgrounds, and to address consistency and reproducibility of the assessment process. Important lessons were learned about factors that influenced the utility of the test collections including topic design, annotations provided by judges, methods used for identifying and training judges, and providing a central moderator “meta-judge”.  相似文献
