In passing, it should be noted that the most important contributing factor the the drop-out rates at each level is the increasing cost of education in China. The schools are charged a variety of fees by the local authorities, which are then passed along to the students. One trade union study of primary and middle schools in Chongqing, a very large city in the Sichuan Province, revealed that the average cost of miscellaneous fees for primary students in 1994 was 95.9 yuan; for junior and senior secondary students, the average fees totaled 155.5 yuan and 257.3 yuan, respectively.
Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
