The Legacy of the X-15

The X-15 established such widespread confidence in aerodynamic, thermal, and structural areas that new designs for operation aircraft for any speed regime could be expected to be successfully achieved if good use was made of all pertinent test facilities and analytical methods. This philosophy guided design of the space shuttle and is the real legacy of the X-15. The accomplishments and contributions attributable to the research and development work on the X-15 that influenced the formative years of the Space Shuttle Program are presented

E-voting in Brazil - the risks to democracy

Literature has shown that countries with strong democratic traditions, such as the United States and Canada, are not yet using electronic voting systems intensively, due to the concern for and emphasis on security. It has revealed that there is no such thing as an error-free computer system, let alone an electronic voting system, and that existing technology does not offer the conditions necessary for a reliable, accurate and secure electronic voting system. In this context, then, what are the risks of e-voting to democracy? In what ways, if at all, can more fragile, less mature democracies be buttressed with e-voting systems? As a key component of e-democracy, it seems that e-voting technologies are to become more secure and increasingly reliable in the near future and will indeed be adopted in many countries. In what ways, if at all, will the introduction of such systems increase voter confidence in the political system, promote citizen engagement in political life, and nurture the evolution of democracy? If both e-voting and edemocracy are emerging based on popular demand - that is, as a demand-driven alternative to current processes, then there is no doubt that they are likely to enhance and improve the efficiency of traditional democracy. However, if e-voting technology is being introduced based on a supply-driven fashion - the technology exists therefore it should and must be implemented - then the implications for democracy should be considered. Brazil's introduction of e-voting offers a cautionary tale of supply-driven technological implication. The purpose of this paper is to demonstrate how the introduction of e-voting in Brazil is highly risky to democracy due to the lack of emphasis on security and the lack of a sociallyinformed and socially driven approach to technological innovation. The Brazilian example illustrates the democratic implications of a market-driven approach. The lack of a technology strategy designed to promote and extend democratic principles is not surprising given the closed door, market-based negotiations that led to the adoption of e-voting in Brazil. The promise, and indeed, the imperative of a democratic, voter-centered approach as an alternative for the development of an electronic voting system, is explored in the paper

The Breast Implant Controversy: A Prism for Reform

The author argues that regulatory blunders and the litigation explosion pertaining to breast implants highlight defects in U.S. administrative and tort law systems

Feeding a Population: Agricultural Education Priorities in Haitian History

The nation of Haiti has experienced a long history of poverty and of tests to its economic development. Among its priorities has been the establishment of an effective educational system. While educational standards remain high, the area of agricultural education—necessary for Haiti’s economy as well as nutritional subsistence—has met with unique challenges. This paper examines analyses and programming policies of the past in order to illuminate contemporary circumstances

SNEAKERS: A Concurrent Engineering Demonstration System

Concurrent Engineering (CE) has already initiated a cultural change in the design and manufacturing of new products. It is expected to lead to better engineered and faster built products. But, in order for a company to take advantage of the power of CE, the members of product development teams have to be educated in the CE method of product development and how decisions made about one aspect of a design can affect other aspects. They also have to be educated in the usefulness of the tools that can be used for CE. Those tools include intelligent agents which can be used to offer design suggestions and criticisms. The goal of this project is to build a computer system which will simulate a design environment and demonstrate the essential aspects of CE, in a way that they can be intuitively understood. It is supported by a grant from the Competitive Product Development Institute at the Digital Equipment Corporation
