When the world grows smaller: Renewing instruction methods for international students

Please note: This is a conference proceeding from an interactive session at the 2008 LOEX Conference. Abstract: With globalization diversifying our university culture, American universities are welcoming an increasing population of international students. Librarians are searching for innovative instruction ideas that adapt to international learning styles while crossing cultural and language barriers. This interactive session taught using the Cephalonian method will combine audience participation, visuals and music in an effort to demonstrate and generate ideas among participants. Framed by the overhaul of the University of Illinois’ ESL instruction program, we’ll talk about characteristics of learning styles of international students, share ideas on pioneering instruction segments including online tutorials and games and discuss authentic assessment strategies.published or submitted for publicationis peer reviewe

Solar total energy-large scale experiment, Shenandoah, Georgia

The design and development of a 7 meter diameter parabolic dish solar collector are discussed. Each of the four main subsystems of the collector: (1) reflector, (2) mount and drives, (3) receiver and (4) the controls, is discussed briefly with the major emphasis on the receiver design. To minimize development risks and production costs, a dish design based on use of stamped aluminum petals (sectors) was chosen. This design is similar to the design of a communication antenna already commercially produced. The reflective surface of the petals has a total reflectance of .86 and a specularity (dispersion) of 8 mrd. This performance is obtained by mechanical polishing and chemical brightening of the petal surface, followed by application of a clear RTV silicone protective coating. Selection of the material and weather proofing coated are discussed. Results from performance tests on an engineering development dish collector are presented and compared with pretest predictions

Characterizing Extragalactic Anomalous Microwave Emission in NGC 6946 with CARMA

Using 1 cm and 3 mm CARMA and 2 mm GISMO observations, we follow up the first extragalactic detection of anomalous microwave emission (AME) reported by Murphy et al. 2010 in an extranuclear region (Enuc. 4) of the nearby face-on spiral galaxy NGC 6946. We find the spectral shape and peak frequency of AME in this region to be consistent with models of spinning dust emission. However, the strength of the emission far exceeds the Galactic AME emissivity given the abundance of polycyclic aromatic hydrocarbons (PAHs) in that region. Using our galaxy-wide 1 cm map (21" resolution), we identify a total of eight 21"x21" regions in NGC 6946 that harbour AME at >95% significance at levels comparable to that observed in Enuc. 4. The remainder of the galaxy has 1 cm emission consistent with or below the observed Galactic AME emissivity per PAH surface density. We probe relationships between the detected AME and dust surface density, PAH emission, and radiation field, though no environmental property emerges to delineate regions with strong versus weak or non-existent AME. On the basis of these data and other AME observations in the literature, we determine that the AME emissivity per unit dust mass is highly variable. We argue that the spinning dust hypothesis, which predicts the AME power to be approximately proportional to the PAH mass, is therefore incomplete.Comment: 12 pages, submitted to MNRAS, comments welcom
