The pilot issue of the data collection of the All-Russian Institute of Scientific and Technical Information of the Russian Academy of Sciences “Industry of Nanosystems and Nanomaterials” gives an approximate view of the state of this field of science at the beginning of 2007. The topics of articles in the pilot issue are analyzed. The directions of development of nanotechnologies are shown. The basic types of nanomaterials, the methods of their production, and their properties and applications are given. 相似文献

Information asymmetry and information sharing 总被引:1,自引:0,他引:1

Although much digital divide research focuses on access to technology, another cause of the divide is the lack of information awareness that we call information asymmetry. Information asymmetry often stems from inadequate information sharing and can result in negative consequences for both the information poor and the information rich. Information asymmetry has been insufficiently studied as a possible cause of underdevelopment and inequality. In response, we develop a typology to classify information asymmetry into two categories, horizontal and vertical, and then identify those information sharing practices that cause the imbalance. To illustrate the negative consequences of information asymmetry and the potential benefits of information sharing, we discuss two examples from the experiences of modern American Indian tribes. First, Indian tribes face horizontal information asymmetry when they attempt to access the capital markets, and second, they face vertical information asymmetry in terms of law enforcement data sharing. This article also describes our ongoing examination of horizontal information sharing among tribes and vertical information sharing between tribes and others sovereigns in the American polity as possible solutions to the problems created by information asymmetry. These strategic responses are embodied in two information systems, the Tribal Financial Information Clearinghouse and an Intergovernmental Tracking System for sharing law enforcement data. We conclude with a discussion of how our typology can be more generally applied to other instances of information asymmetry. 相似文献

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions. 相似文献

It is increasingly important for government agencies to collaborate across jurisdictional and functional boundaries. Interorganizational systems supporting interagency collaboration must accommodate a wide range of factors from the external environment and participating organizations as part of their design and operation. This paper presents the findings from a case study of CapWIN, a collaborative network created to enable first responders to share information across jurisdictional and functional boundaries as they work together during emergencies and other critical events. The study examines how aspects of the external environment and the agency context impeded or facilitated the CapWIN collaborative network and the interorganizational system (IOS) that supports it. We identify factors affecting information sharing and collaborative processes, and describe how these factors interact to enable and constrain an IOS. The paper concludes with suggestions for further research on the interplay of environmental, organizational, and technical aspects of interagency collaboration networks as they evolve over time. 相似文献

All living organisms are affected by natural or induced modifications of their surrounding physical environment. A distinct relationship exists between the health of the environment and the health of the individuals living in it. This paper presents a selection of resources about environmental health resources readily accessible on the Internet in October 1998. 相似文献

In the summer of 2004, it was revealed that the U.S. Census Bureau had provided tabulations in 2002 and 2003 on Arab Americans to the Department of Homeland Security that included detailed information on the number of people of Arab backgrounds living in selected ZIP codes. Although not a violation of law, the Census Bureau realized that this perceived breach of confidentiality would have a negative impact on public trust, and within a few months following the news of the Arab American tabulations it announced that it would no longer assist law enforcement and intelligence agencies with tabulations on ethnic groups and other sensitive populations. In spite of this damage control, we believe that the Bureau's tabulation of Arab Americans provides momentum to a process that adversely affects data quality by increasing both non-response and the cost of obtaining survey and census data. We argue that there are no “methodological fixes” that can repair the damage, and further that public relations campaigns and internal administrative changes are not optimal solutions because of the governing structure within which the Bureau currently operates. Ultimately, the best way to limit the damage already done is to effect a political solution. Toward this end we describe short- and long-term actions. In the long run, we recommend removing the Census Bureau from the Executive branch of government and re-structuring it under a permanent and non-political oversight panel similar to either the Federal Reserve Board or the Congressional Budget Office. Such a move would make a strong statement that the Bureau is non-partisan federal statistical agency. 相似文献
