    AB the Twentieth Century began, there was a traditional posture evident in higher education in the United States. For those males whose families could afford it, beginning college immediately following high school provided a liberal arts education. For select 21 year old college graduates, specialization in a professional field was available in graduate school. For the remainder of America\u27s youth, and nearly all of its women, high school graduation was the highest academic pinnacle they might obtain for the remainder of their life

    Darwin Would Be Justifiably Proud

    As the international aviation community awaits U.S. government action on the report of the National Commission to Ensure a Strong Competitive Airline Industry (1993), Charles Darwin would be justifiably proud. The obvious survival-of-the-fittest struggle that many U.S. airlines have faced since deregulation and the evolutionary posture of a growing group of profitable carriers, led by Southwest Airlines, seem to be a fulfillment of his theories

    Evolution of an Effective Speaking Across the Curriculum Program

    Get PDF
    The author wishes to acknowledge the wonderful speaking across the curriculum programs extent across America, and especially those administrators and faculty who have dedicated themselves to this essential movement. The need for articulate and even forceful speakers will only grow in this new millennium. A debt of gratitude is due Dean Emeritus Robert Hall, whose insightful vision and internal grant approval launched ERAU\u27s Computing Across the Curriculum Program in 1993. This CATC program has evolved into a quadratic effort, now including computing, critical thinking, speaking and writing across the curriculum

    Multi-layer light-weight protective coating and method for application

    Get PDF
    A thin, light-weight, multi-layer coating is provided for protecting metals and their alloys from environmental attack at high temperatures. A reaction barrier is applied to the metal substrate and a diffusion barrier is then applied to the reaction barrier. A sealant layer may also be applied to the diffusion barrier if desired. The reaction barrier is either non-reactive or passivating with respect to the metal substrate and the diffusion barrier. The diffusion barrier is either non-reactive or passivating with respect to the reaction barrier and the sealant layer. The sealant layer is immiscible with the diffusion barrier and has a softening point below the expected use temperature of the metal

    Oxidation characteristics of Beta-21S in air in the temperature range 600 to 800 C

    Get PDF
    The metastable beta-Ti alloy Beta-21S, Ti-15Mo-2.7Nb-3Al-0.2Si (weight percent), has been proposed as a candidate for use in metal matrix composites in future hypersonic vehicles. The present study investigated the oxidation behavior of Beta-21S over the temperature range 600 C to 800 C. Oxidation weight gain was evaluated using thermogravimetric analysis. Oxidized specimens were evaluated using x ray diffraction techniques, scanning electron microscopy, energy dispersive x ray analysis, and electron microprobe analysis to identify oxidation products and evaluate oxidation damage to the alloy

    Maximizing Student Learning Through the Creation of a Positive Classroom Environment

    Get PDF
    The ERAU Extended Campus has short academic terms, a multimodal delivery system, a highly mobile student body, and some 3,000 faculty teaching. They face a more challenging task of creating a positive classroom environment than most traditional universities and programs. The researchers sought to both assess the presence of a positive learning environment and to bridge the gap between the present EC classrooms and a world class learning environment. Five graduate and three undergraduate classes at six locations in three states in ERAU Southwest Region were sampled using a researcher-designed survey. Fifty-three respondents indicated that Embry-Riddle\u27s Extended Campus is providing them a very positive learning environment, identified best-practices desired in the classroom environment, and offered constructive criticism. The researchers recommended that the ERAU EC Center for Teaching and Learning Effectiveness create a positive learning environment module based on this research for dissemination to all Extended Campus faculty

    Why Do Shoppers Shop?

    Get PDF
    The purpose of the present study was to assess the relationships between three potential motivators of shopping behavior with a measure of attitude toward shopping. Data from 306 US student consumers were collected via an online survey. Reliable and valid scales operationalized the constructs. The results showed that shopping appears to be motivated in part by a desire for status, by materialism, and by brand engagement in self-concept. The results also showed women like to shop more than men do and that the relationships among the variables differed between men and women, suggesting that each gender is motivated to shop for different reasons

    Oxidation characteristics of Ti-14Al-21Nb ingot alloy

    Get PDF
    Static oxidation kinetics of Ti14Al21Nb (wt pct) ingot alloy were studied in air over the temperature interval of 649 to 1093 C in a thermogravimetric apparatus. The oxidation products were characterized by x ray diffraction, electron microprobe analysis, energy dispersive x ray analysis, and Auger electron spectroscopy. Cross-sections of the oxidized samples were also examined using light and scanning electron microscopy. The oxidation rate was substantially lower than the conventional alloys of titanium, but the kinetics displayed a complex behavior involving two or more oxidation rates depending on the temperature and duration of exposure. The primary oxide formed was TiO2, but this oxide was doped with Nb. Small amounts of Al2O3 and TiN were also present in the scale. Diffusion of oxygen into the alloy was observed and the diffusivity seemed to be dependent on the microstructure of the metal. A model was presented to explain the oxidation behavior of the alloy in terms of the reduction in the oxygen diffusivity in the oxide caused by the modification of the defect structure of TiO2 by Nb ions

    Teaching Techniques for the Long Haul

    There is not a faculty member who has taught the adult learner in the non-traditional environment that has not pondered the question of how it is you keep a class going for four or five hours. I have talked with quite a number who have even reached a conclusion- You cannot! So just make the best of a bad situation. WRONG!!! There are proven strategies and techniques for keeping a class going and doing it week after week, term after term. And, believe it or not, it can be done without an inordinate dependence on there I was at 20,000 feet ... The answer cannot be found solely in traditional strategies and techniques--and that is where most of us are looking. The answer does emphasize multi-media presentations, simulations and gaming, and active participation and interaction by both faculty and the adult learner (the operative word being, active )

    Mechanical properties of coated titanium Beta-21S after exposure to air at 700 and 800 C

    Get PDF
    Mechanical properties of Beta-21S (Ti-15Mo-3Al-2.7Nb-0.2Si, wt percent) with glass, aluminide, and glass-on-aluminide coatings less than 3-micron thick were studied. Coatings were deposited by sol-gel processing or electron-beam evaporation onto 4.5-mil (113-micron) thick Beta-21S sheet from which, after oxidizing in air at 700 or 800 C, tensile test specimens were machined. Plastic elongation was the most severely degraded of the tensile properties; the glass-on-aluminide coatings were the most effective in preventing degradation. It was found that oxygen trapping by forming oxides in the coating, and reactions between the coatings and the Beta-21S alloy played significant roles
