AbstractThe significance of teaching the basics of engineering education in middle- and high-schools is generally acknowledged by policy makers, teachers and researchers in the U.S.A. as well as a number of developed and developing countries. Nevertheless, engineering topics are rarely covered by precollege curriculums. A key contributing factor is that engineering hinges on the usage of technology to expose learners to fundamental concepts otherwise difficult to demonstrate. For example, learning the concepts of systems' design, optimization, and trade-offs can be a challenging task when teachers and students limited access to tools to practice their engineering knowledge. Thus, a deficiency of operational learning technologies for diverse precollege environments affects the availability of engineering learning experiences. The aim of this dissertation is to unveil the relationships between influential factors for the advancement of precollege engineering education. We proposed a framework for the development of curriculum and technology derived from analyzing design issues from the perspective of multiple entities encompassing a broad of stage holders including students, teachers and technology developers. Several influential factors are considered including human-computer interaction issues, the problem of a digitally divided population and the lack of engineering curriculum that reconciles precollege engineering education with state and national educational standards. The findings of this dissertation are based on quantitative and qualitative re- search performed during a four year span working with five local schools in the Tucson Unified School District.

A RHETORIC OF TECHNOLOGY: COERCION AND INTERVENTION IN TECHNOLOGY PRODUCTION AND UTILIZATIONMenchaca, David Anthony (The University of Arizona., 2009)In this work I propose that the rhetoric of technology is a kind of machinery of meaning-making that creates symbolic technologies that exist parallel with, but are distinct from, the material technologies they represent. The creation of symbolic technologies is dynamic and influenced by multiple and disparate communicative and ideological operations ranging from the writing and reading of technical manuals to processes of cultural indoctrination. As such, I use Barry Brummett's Rhetorical Dimensions of Popular Culture to demonstrate that technology is a coercive cultural force I call techno-culture. Under the influence of techno-culture, technical manufacture must be viewed as technology production and technical use must be viewed as technology utilization. This reformulation of terms emphasizes the fact that technology is manufactured and used according to the preferred significations of techno-culture. Fortunately, as the rhetoric of technology uncovers the processes by which techno-culture propagates hegemonic structures, the rhetoric of technology also provides users and manufacturers with the means to intervene. Metaphor and metonymy, as modes of meaning-making, are those means.
Can Mobile Communication Technologies Enhance Knowledge and Technology Transfer for Improved Agricultural Productivity in Developing Nations? A Preliminary Macro-Economic Assessment in KenyaVancel, James Hugh (The University of Arizona., 2012-05)Agriculture is central to the economy of Kenya, but as the population dependent on the same land grows, farmers have been compelled to develop more intensive practices to produce similar yields as in the past. Investments in agricultural research and technology facilitate this intensification and have historically resulted in substantial gains. However, efforts to promote effective transfer of new technologies and methodologies have been stifled by financial challenges to traditional agricultural extension delivery approaches. Extension services involve significant face-to-face contact in farmer fields, through farmer field schools, or at regional events. However with rising costs, the demand for more mobile and adaptable mediums is apparent. This study examines the potential for new methods of knowledge and technology transfer and diffusion of innovation within Kenya, most notably the use of mobile phone services. In order to frame the potential of such services, a national level macro-econometric analysis was undertaken to assess the effects of investments in agricultural research on agricultural gross domestic product. These results were then overlaid on an analysis of 14 case studies examining the effects and challenges of agricultural extension in East Africa. Three potential services, Awaaz De, FarmFox, and Community Knowledge Workers (CKW), were then assessed on a capabilities standard in the context of the rise of the mobile communication markets in Kenya for potential application to extension services. The results indicate that agricultural research is strongly correlated with growth in agricultural GDP and that effective extension services have strongly facilitated that in the past. However, limited flexibility, lack of farmer input, and high costs limit that potential contribution to growth. Mobile communication services may be part of the solution; capabilities of Awaaz De, FarmFox, and CKW are promising, but further research is needed to accurately recommend a service for Kenya’s extension services.
THE MIDCOURSE SPACE EXPERIMENT - AN ADVANCED TECHNOLOGY DATA SYSTEM FOR AN ADVANCED TECHNOLOGY PROGRAMGriffin, Alan R.; McInerney, R. E.; McDonough, James K.; Babcock, Richard R. (International Foundation for Telemetering, 1996-10)The Midcourse Space Experiment (MSX) program is the premier space technology experiment of the Ballistic Missile Defense Organization (BMDO) that addresses BMDO system development requirements. The primary objective of the experiment is to collect and analyze data on target and backgrounds phenomenology using three multi-spectral (ultraviolet through infrared) imaging sensors. The program also has objectives for space-based space-object surveillance, assessing space contamination effects, and investigating atmospheric and space phenomenology. Effective scientific Data Management is one of the critical functions within the MSX program organization and is key to meeting the program objectives. The wide spectrum of objectives and requirements of the MSX program were major drivers in the design of a Data System with a heterogeneous, distributed processing center concept and a dual data flow path to meet sensor assessment and experiment analysis requirements. An important technology decision that evolved from this design was the exclusive use of workstation class computers for data processing. A flexible, highly robust development and testing methodology was created to implement this unique system. Companion papers in this session provide detailed descriptions of functions of key elements in the Data System operations.
