The Social Construction of Chinese Models of Teaching

Five principal relationships, derived from long-standing Confucian values, are described as the cultural and social foundation for Chinese models of teaching. Three related models of teaching will be described during the presentation: Teacher as master; teacher as virtuoso; and teacher as coach

Acc #: 268; MMWB 001 This interview with Jean Hansen, Ethel M. “Perry” Capley, Irene McLeod, Doris D. McBride, and Mavis Martin was recorded by Martha Mercer on May 12, 1992 in Mrs. Hansen’s home. The main topic of the interview revolves around the women\u27s experiences marrying American GIs during World War II and moving to the United States. The interview begins with the women discussing their lives in Britain before the during the war, and how their families made their respective livings. They discuss their experiences traveling to America on ships, reflection on the immigration process itself and their interactions with immigration officials, and the difficulties of return travel to visit Britain afterward. They also discuss their adjustment to life in the American South as white women from the UK, and their first impressions of Mobile, and reflect on how living in Mobile has affected their sense of home. The interview concludes with discussion of the Mobile-based women’s club that they founded, originally named the British Brides’ Club. This interview is part of a collection of three audio cassette recordings and one written interview that Martha Mercer conducted with white World War II war brides from the UK and Australia in 1992-93. Mercer undertook the project for her master’s thesis in History, “British Brides, American Wives: The Immigration and Acculturation of War Brides in Mobile, Alabama, 1945-1993,” which she completed at the University of South Alabama in 1993

Energy Conversion via Metal Nanolayers

Current approaches for electric power generation from nanoscale conducting or semiconducting layers in contact with moving aqueous droplets are promising as they show efficiencies of around 30%, yet even the most successful ones pose challenges regarding fabrication and scaling. Here, we report stable, all-inorganic single-element structures synthesized in a single step that generate electrical current when alternating salinity gradients flow along its surface in a liquid flow cell. Nanolayers of iron, vanadium, or nickel, 10 to 30 nm thin, produce open-circuit potentials of several tens of millivolt and current densities of several microA cm^(−2) at aqueous flow velocities of just a few cm s^(−1). The principle of operation is strongly sensitive to charge-carrier motion in the thermal oxide nanooverlayer that forms spontaneously in air and then self-terminates. Indeed, experiments suggest a role for intraoxide electron transfer for Fe, V, and Ni nanolayers, as their thermal oxides contain several metal-oxidation states, whereas controls using Al or Cr nanolayers, which self-terminate with oxides that are redox inactive under the experimental conditions, exhibit dramatically diminished performance. The nanolayers are shown to generate electrical current in various modes of application with moving liquids, including sliding liquid droplets, salinity gradients in a flowing liquid, and in the oscillatory motion of a liquid without a salinity gradient
