The energy industry, especially the petroleum, is critically important to today's society. This industry has historically been accused of being a “good old boy” network that is extremely reluctant and slow to accept technology and change. A closer analysis of the industry shows that it is highly fragmented consisting mostly of firms who operate in only a limited number of functional areas. The analysis also shows that there are many critical current and future problems which could be addressed with technology from any diverse disciplines and industries. Case analyses of existing technology flow through to successful utilization by the petroleum industry describes the technology transfer process and the role played by the different firms inside and outside the industry. 相似文献

A network of 29 Sea Grant Programs now operate in almost all of the 34 eligible coastal and Great Lake states, the Commonwealth of Puerto Rico, and the U.S. Island Territories. Operating in response to current needs and opportunities by applying faculty, research staff and student expertise, Sea Grant Programs have developed many new systems, processes, policy and legal studies, and technologies. These have been effectively transferred to user groups, including major industries, businesses, government agencies, citizen groups and individuals. Many examples of successful technology development and transfer are discussed. Some examples are the hydrodynamic modeling of transport and dispersion of pollutants in large definable water bodies, the demonstration of a prototype machine for skinning the Spiny Dogfish Shark and application of vibration studies to reduce wave response of offshore structures. The examples demonstrate the viability and effectiveness of the Sea Grant concept. 相似文献

A unique longitudinal study of the technical communication patterns of 184 engineers in a high technology research and development laboratory centers in the activities of technology gatekeepers. This two-step flow of technical information follows the literature as well as results from prior studies. Gatekeepers span the organizational boundary in the transfer of technology from outside the laboratory, while facilitating the distribution of technical information to colleagues within the organization. Sociometric data are analyzed over a five-year period with respect to changing organizational structures, new technical assignments and alterations in group composition. Despite these dynamic changes, the data reveal consistent results in gatekeeper identification and technical information flows. 相似文献

The structure and organization of the middle tier of higher education in similar institutions in the U. K. and U. S. are compared to draw conclusions on the effect which differences and similarities have upon the quality of the educational process, its cost-effectiveness, student independence and maturity, faculty load, relationships with business, industry and government. 相似文献

This paper presents a study of the concepts of transferring computer technology among city governments. A sample of cities from a domestic population and an international population are used as the basis of the research. Contrary to expectation, and for both populations, the survey indicated the level of computer applications transfer among cities was found to be low compared to the amount of total application development. It was determined that an important source of transfer information was from “centers” such as the federal government, vendors, and transfer agencies, rather than city to city. International cities that were studied seem to experience a propensity toward centralized control at the national level. These controls often include the transfer of technical information. Further, the types of transfer may vary widely between the domestic vs the international cities. That is, domestic city transfers tend to be operations-oriented, while transfers from national centers tend to be management oriented. In general the study supported prior conclusions concerning the difficulties of transfer. The problem of mismatch and difficulties in modification make transfers very risky. Even so, there are many persons willing to take the risks in order to try to achieve lower costs and to realize the opportunity to obtain sophisticated applications. 相似文献
