Self-aligning fixture used in lathe chuck jaw refacing

Self-aligning tool positions and rigidly holds lathe chuck jaws for refacing and truing of the clamping surface. The jaws clamp the fixture in the manner of clamping a workpiece. The fixture can be modified to accommodate four-jawed checks

Promover la educación científica a través de las tecnologías de la información y comunicación (TIC)

La educación científica debe preparar a los estudiantes para analizar y evaluar los avances tecnológicos, desde el láser al genoma humano. A fin de planificar el cuidado de la propia salud o elegir una nueva residencia, los ciudadanos deben evaluar alternativas que reflejan avances tecnológicos. A medida que la ciencia y la tecnología avanzan, los ciudadanos necesitan desarrollar la capacidad de responder a nuevas alternativas y de criticar mensajes persuasivos sobre muchas cosas, desde medicamentos hasta materiales de construcción. El Web-based Inquiry Science Environment (WISE) ayuda a los estudiantes y diseñadores de currículo que buscan alcanzar estos objetivos. A medida que experimentamos con programas educativos para alcanzar estos objetivos, nos beneficiamos de la colaboración internacional y de la comunicación. Cuanto más podamos aprender los unos de los otros, más puede mejorar nuestra educación científica.Science education must prepare students to analyze and assess advances in technology from lasers to the human genome. To plan one's health care or select a new residence, citizens must evaluate alternatives that reflect technological advances. As science and technology advance, citizens need the ability to respond to new alternatives and to criticize persuasive messages about everything from drugs to building materials. The Web-based Inquiry Science Environment (WISE) supports students and curriculum designers who seek to achieve these goals. As we experiment with educational programs to meet these goals we benefit from international collaborations and communication. The more we can learn from each other the better our science education can become

International Security and the War Powers Resolution

In recent history, the authority to commit US. troops to theaters of conflict has shifted from Congress to the President. After the Vietnam War, the War Powers Resolution was written to reestablish balanced authority over war between the political branches of government. In the post-Cold War era, forces frequently are deployed as part of multilateral UN. operations. This trend creates two contradictory needs: first, the need for the Executive to be able to act swiftly and decisively in formulating military commitments to the United Nations, and second, the need for Congress to authorize potentially long-term military deployments. To reconcile these contradictory needs, the President should be required to consult with a small group of key congressional actors before committing US. troops. to multilateral UN, military operations. There are both legal and security rationales for this. Centrally, Executive-congressional consultation re-solidifies the constitutional allocation of war powers and may bolster US. credibility in multilateral operations

An Empirical Investigation of Debt Contract Design: The Determinants of the Choice of Debt Terms in Eurobond Issues

This paper provides a comprehensive analysis of the determinants for the optimal choice of contract terms on Eurobonds issued by UK companies. We examine predictions of extant theories that associate the choice of debt features namely, maturity, call options, convertible options, and protective covenants to firm and market characteristics. Like in Correia (2003), a simultaneous equations approach is adopted to test the alternative use of contract features for mitigating debt-contracting costs. The evidence provides strong support to the prediction that both callable and short-term debt and convertible and debt with protective covenants are used as alternative control devises to mitigate agency costs. Further evidence suggests, however, that contrary to the fundamentals guiding the choice of maturity and callability structures, the use of conversion options and protective covenants in Eurobond contracts seems to be determined by equity agency costs rather than debt agency costs. Also, some support is found for the risk uncertainty theory underlying the use of convertibles and for liquidity risk arguments regarding the choice to include protective covenants.

The Hybrid Master\u27s Degree: Combining Research with Practice

The article discusses the development of a hybrid master degree program by the Donald W. Reynolds School of Journalism at the University of Nevada in Reno. Since the journalism faculty of the school is too small to offer a full-service master\u27s degree, the school developed a hybrid program that integrates systematic research with practice-based education. The program is designed to equip students with knowledge in academic research in preparation to doctoral studies. The program also emphasizes the study of mass media to prepare students for professional careers in broadcast journalism

Lifelong science learning: A longitudinal case study

How do students link school and personal experiences to develop a useful account of complex science topics? Can science courses provide a firm foundation for lifelong science learning? To answer these questions we analyze how "Pat" integrates and differentiates ideas and develops models to explain complex, personally-relevant experience with thermal phenomena. We examine Pat's process of conceptual change during an 8th grade science class where a heat flow model of thermal events is introduced as well as after studying biology in ninth grade and after studying chemistry in the 11th grade. Pat regularly links new ideas from science class and personal experience to explain topics like insulation and conduction or thermal equilibrium. Thus Pat links experience with home insulation to experiments using wool as an insulator. This linkage leads Pat to consider "air pockets" as a factor in insulation and to distinguish insulators (with air pockets) from metal conductors that "attract heat." These linkages help Pat construct a heat flow account of thermal events and connect it to the microscopic model introduced in chemistry. Pat's process of conceptual change demonstrates how longitudinal case studies contribute to the understanding of conceptual development. Future work will synthesize the conceptual change process of all 40 students we have studied longitudinally
