Defense R&D and information technology in a long-term perspective la rd militaire et les technologies de l'information en longue période

Defense R&D is usually considered as an economic burden, implying an eviction effect on civilian R&D and perverting the national systems of innovation. If arms production benefits nowadays from advanced civilian R&D, the flow of technology was not always in the same direction–especially in the 1950s and 1960s. Moreover, since the beginning of the 1990s, some technologies, classified for a long time as purely defense ones (GaAs, GPS, computer networking, etc.), have found new civilian applications. Why technological opportunities created by defense R&D are not systematically seized by commercial firms? First, technology transfers come true only when a legal framework exists and allows commercial firms to get access to the « military technological fund ». Second, the global economic context appears as the greatest incentive to engage civilian firms in exploiting defense technologies, as an investment opportunity. In a long-term perspective, when specific conditions are set up or exist, defense R&D can become a means of strengthening the international competitiveness of national economies. La RD de défense est souvent considérée comme un fardeau pour l'économie, impliquant un effet d'éviction sur la RD civile et pervertissant le système national d'innovation. Si la production d'armements profite aujourd'hui des avancées de la RD civile, le flot de technologies n'a pas toujours été dans la même direction – tout particulièrement dans les années 1950 et 1960. De plus, depuis le début des années 1990, quelques technologies, longtemps classées comme purement militaires (GaAs, GPS, réseaux informatiques, etc.), ont trouvé de nouvelles applications civiles. Pour quelles raisons les opportunités technologiques créées par la R&D de défense ne sont-elles pas systématiquement saisies par les firmes commerciales ? Premièrement, les transferts de technologies se concrétisent seulement quand un cadre légal existe et autorise les firmes commerciales à avoir accès au « fonds technologique militaire ». Deuxièmement, le contexte économique global constitue une incitation importante pour engager les firmes civiles à exploiter les technologies de défense. Dans une perspective de longue période, quand les conditions idoines sont mises en place ou existent, la RD de défense peut ainsi devenir un moyen de renforcer la compétitivité internationale des économies nationales.Defense R&D, Information Technology, international Competitiveness, Global Positioning System, Networking

Evaluating the effectiveness of technology on learning in K-12 education

Demonstrating an impact on student learning due to technology innovations is extremely important in K-12 education. Billions of dollars have been spent on technology in education in the past several years. Stakeholders are demanding to know if this investment is impacting student learning and achievement. However, the assessment of technology in K-12 education is complicated due to the changing nature of technology and all of the variables involved in education. The purpose of this paper is to discuss the rationale for evaluating technology.in education, analyze the issues involved in evaluation, review current research on the impact of technology on student learning, and discuss guidelines for effective assessment of technology in K-12 education

Lunar base mission technology issues and orbital demonstration requirements on space station

The International Space Station has been the object of considerable design, redesign, and alteration since it was originally proposed in early 1984. In the intervening years the station has slowly evolved to a specific design that was thoroughly reviewed by a large agency-wide Critical Evaluation Task Force (CETF). As space station designs continue to evolve, studies must be conducted to determine the suitability of the current design for some of the primary purposes for which the station will be used. This paper concentrates on the technology requirements and issues, the on-orbit demonstration and verification program, and the space station focused support required prior to the establishment of a permanently manned lunar base as identified in the National Commission on Space report. Technology issues associated with the on-orbit assembly and processing of the lunar vehicle flight elements are also discussed

Computational needs survey of NASA automation and robotics missions. Volume 1: Survey and results

NASA's operational use of advanced processor technology in space systems lags behind its commercial development by more than eight years. One of the factors contributing to this is that mission computing requirements are frequently unknown, unstated, misrepresented, or simply not available in a timely manner. NASA must provide clear common requirements to make better use of available technology, to cut development lead time on deployable architectures, and to increase the utilization of new technology. A preliminary set of advanced mission computational processing requirements of automation and robotics (A&R) systems are provided for use by NASA, industry, and academic communities. These results were obtained in an assessment of the computational needs of current projects throughout NASA. The high percent of responses indicated a general need for enhanced computational capabilities beyond the currently available 80386 and 68020 processor technology. Because of the need for faster processors and more memory, 90 percent of the polled automation projects have reduced or will reduce the scope of their implementation capabilities. The requirements are presented with respect to their targeted environment, identifying the applications required, system performance levels necessary to support them, and the degree to which they are met with typical programmatic constraints. Volume one includes the survey and results. Volume two contains the appendixes

Teachers\u27 perceptions of computer technology\u27s impact upon student achievement

The purpose of this study was to determine if computer technology is an effective tool for raising student achievement in education. Much of the related research indicated there is a pressing need for educators, at both the school site and district levels, to develop accurate assessment tools to accurately determine the most effective use of computers as it applies to instructional technology

Considerations for a design and operations knowledge support system for Space Station Freedom

Engineering and operations of modern engineered systems depend critically upon detailed design and operations knowledge that is accurate and authoritative. A design and operations knowledge support system (DOKSS) is a modern computer-based information system providing knowledge about the creation, evolution, and growth of an engineered system. The purpose of a DOKSS is to provide convenient and effective access to this multifaceted information. The complexity of Space Station Freedom's (SSF's) systems, elements, interfaces, and organizations makes convenient access to design knowledge especially important, when compared to simpler systems. The life cycle length, being 30 or more years, adds a new dimension to space operations, maintenance, and evolution. Provided here is a review and discussion of design knowledge support systems to be delivered and operated as a critical part of the engineered system. A concept of a DOKSS for Space Station Freedom (SSF) is presented. This is followed by a detailed discussion of a DOKSS for the Lyndon B. Johnson Space Center and Work Package-2 portions of SSF

An appraisal on the Role of Technology in Modern Education, Opportunities and Challenges

The influence of technology in modern education is a transformative force that has changed the learning and teaching process in contemporary education. This study investigates several aspects of the impact of technology on education, with emphasis on both the opportunities and challenges it presents. Technology's benefits in education have shown that accessibility and diversity in education have risen in rapid technological growth due to digital resources and personalised learning possibilities. The implication showcases that technology would better enhance an inclusive education that accommodates diverse learners and ensures interactive learning, bearing in mind the global connectivity of technology. Despite technology's immense possibilities and benefits in modern education, it should be managed appropriately to avoid challenges such as privacy and security concerns and ethical and societal considerations. There is a need for strategic planning, strong policies, and professional development to ensure the closing of digital gaps within education to exploit the potential of technology while tackling its related issues
