A survey of the material and intellectual consequences of trading in undocumented ancient coins : a case study on the North American trade
Ancient coins are among the most widely collected and demanded objects among American collectors of antiquities. A vocal lobby of ancient coin dealers/collectors has arisen to protect the importation of undocumented material into the United States and also seeks to make a distinction between antiquities trafficking and that in ancient coins. Coins are an equally important historical source and are no less important 'antiquities' than a Greek painted vase. I examine the scale of the trade in ancient coins in North America and address some points made by proponents of a continued unfettered ancient coin trade
Seeing is believing. Or is it?: visual literacy in art & design education
Visual forms of communication are dominant in the digital era. As the visual has increased in influence throughout contemporary culture, art & design slide collections, which would have traditionally helped users make sense of the visual world, have begun to rapidly disappear. How are students of art & design (and beyond) engaging with this visual proliferation now they can no longer rely on the support of the institutional slide collections and their expert staff
High pressure space suit glove
The High Pressure Space Suit Glove Program yielded one prototype glove assembly with an operating pressure of 8.0 psi. The following developments are reported: (1) A new layup technique for incorporation of the mini-convolute systems; (2) modification in the mini-convolute construction to assure cycle life at 8.0 psi in excess of 100,000 cycles; (3) the development of a unique non-orthogonal low torque wrist joint; (4) the development of a low torque single axis joint for use in the thumb and finger first metacarpal joints; and (5) a number of approaches to 1st metacarpal joints were fabricated and tested to establish the joint technqiues
EET Senior Design Project - IMS Dynamic Display
Indiana University Purdue University IndianapolisThe Indianapolis Motor Speedway Museum has a display transmission that is still
actively used in IndyCar today. The museum wants to incorporate this transmission into an
interactive display, so guests of all ages can see internal gears spin as well as see the
transmission shift between its gears. This project includes mechanical and electrical engineering technology students working together to mount wire motors and sensors. The transmission will have a user-friendly interface allowing the guests to change gears and to turn the transmission on and off. The transmission will be driven by a 24V DC motor and uses a 24V DC linear actuator to rotate a barrel cam to change the position of the forks, allowing the gears to get shifted up and down. A metal enclosure houses the electrical components that provide power and control to the system. The outcome of this project is a failsafe and robust system that will operate within the IMS Museum while being continually updated.Electrical Engineering Technolog
Bridging the Gap Between Inclusive Policy and Inclusive Culture in Secondary Schools
Organisational support from a number of levels needs to be in place if schools are going to achieve success in developing an inclusive school culture. Support at policy level is frequently in place, however the gap between policy and practice is a continuing challenge. In this in-depth study of a secondary school Suzanne Carrington and John Elkins offer insights into the culture of an inclusive school and the processes of translating inclusive policy to inclusive practice
Formation of Early Water Oceans on Rocky Planets
Terrestrial planets, with silicate mantles and metallic cores, are likely to
obtain water and carbon compounds during accretion. Here I examine the
conditions that allow early formation of a surface water ocean (simultaneous
with cooling to clement surface conditions), and the timeline of degassing the
planetary interior into the atmosphere. The greatest fraction of a planet's
initial volatile budget is degassed into the atmosphere during the end of magma
ocean solidification, leaving only a small fraction of the original volatiles
to be released into the atmosphere through later volcanism. Rocky planets that
accrete with water in their bulk mantle have two mechanisms for producing an
early water ocean: First, if they accrete with at least 1 to 3 mass% of water
in their bulk composition, liquid water may be extruded onto the planetary
surface at the end of magma ocean solidification. Second, at initial water
contents as low as 0.01 mass% or lower, during solidification a massive
supercritical fluid and steam atmosphere is produced that collapses into a
water ocean upon cooling. The low water contents required for this process
indicate that rocky super-Earth exoplanets may be expected to commonly produce
water oceans within tens to hundreds of millions of years of their last major
accretionary impact, through collapse of their atmosphere.Comment: 8 text pages with 5 figures following; Accepted at Astrophysics and

Solar Brayton engine/alternator set
Work on the Mod O solar Brayton engine/alternator set is redirected to utilize solarized components of the automotive advanced gas turbine (AGT). The new configuration is referred to as the Mod I. Commercialization of solar Brayton engines thus should be enhanced not only by relating the design to an engine expected to reach the high quantity, low cost production rates associated with the automotive market, but also by the potential the AGT components provide for growth of efficiency and power rating. This growth would be achieved through use of ceramics in later versions making operation possible at temperatures up to 2500 F. The longer program duration and higher cost of the Mod I is considered
Creating Pathways to Develop Student Professionalism - A New Direction
The 2007-2008 academic year brought a new program of student employment to our IT department called IT Fellows. This program brings together the technological skills of IT along with soft business skills to assist our student employees in becoming well-rounded individuals fully prepared for life after college. In previous years our primary area of student employment was the Help Desk in which there was a tiered system in place with opportunities for resume and interview experience, raises, and promotions. The area of training needed further development and the move to the new program provided enhanced opportunities for training at all levels of employment. First-year candidates attend a week-long Leadership Academy, followed by a full year of training in four six-week rotations of their choice, after which they interview for year-long assignments as interns. Internship opportunities are provided in all areas of the department as well as some campus departments outside of IT, and provide transcript credit for them to carry forward in their prospective careers. As they progress, some upper-class Fellows become mentors, coaches, managers, and trainers themselves. All Fellows participate in educational seminars throughout the year which address many areas of technology and professionalism. Come journey with us as we explore the new terrain of students as colleagues, and the benefits of expanding time staff as well as student employees
