Algorithms for Lunar Flash Video Search, Measurement, and Archiving

Lunar meteoroid impact flashes provide a method to estimate the flux of the large meteoroid flux and thus their hazard to spacecraft. Although meteoroid impacts on the Moon have been detected using video methods for over a decade, the difficulty of manually searching hours of video for the rare, extremely brief impact flashes has discouraged the technique's systematic implementation. A prototype has been developed for the purpose of automatically searching lunar video records for impact flashes, eliminating false detections, editing the returned possible flashes, Z and archiving and documenting the results. The theory and organization of the program is discussed with emphasis on the filtering out of several classes of false detections and retaining the brief portions of the raw video necessary for in depth analysis of the flashes detected. Several utilities for measurement, analysis, and location of the flashes on the moon included in the program are demonstrated. Application of the program to a year's worth of lunar observations is discussed along with examples of impact flashes as well as several classes of false impact flashes

U.S. Philanthropy’s Shaping of Management Education in the 20th Century: Toward a Periodization of History

Scholarship on U.S. philanthropic foundations and the Americanization of management education has hitherto focused on specific nations or regions or on particular historical moments. We build on this scholarly corpus to present—for the first time—a meta-history of the 20th century role of U.S. philanthropy in shaping management education around the world. Having outlined the meaning and purpose of “periodization,” we propose three periods. First, within the US from the 1920s post-Progressive Era up to the 1960s, where philanthropic foundations used management education to address U.S. internal social problems and establish its economic preeminence worldwide. Second, Europe post-WWII to the 1980s, where management education was intended to enable Western European reconstruction and fight communism, and later to integrate the Soviet Bloc into the west. Third, the Third World from the post-1945 development era up until the onset of neoliberal globalization, where U.S. foundations’ management education interventions sought the technocratic modernization of former subject nations. In each of these, we conclude, the U.S. foundations’ programs for management education worked to preserve U.S. international interests, and promote U.S. “soft power,” in ways unique to each time/place as well as in ways common across them

The 2014 May Camelopardalid Meteor Shower

On May 24, 2014 Earth will encounter multiple streams of debris laid down by Comet 209P LINEAR. This will likely produce a new meteor shower, never before seen. Rates predicted to be from 100 to 1000 meteors per hour between 2 and 4 AM EDT, so we are dealing with a meteor outburst, potentially a storm. Peak rate of ~200 per hour best current estimate. Difficult to calibrate models due to lack of past observations. Models indicate mm size particles in stream, so potential risk to Earth orbiting spacecraft
