Research on Saudi Arabian communication patterns is inadequate. The present study reviews the literature on Saudi Arabian cultural and communication patterns and reports the results of data collected in Saudi Arabia on the perceived problems of Saudi Arabian businessmen when communicating with Americans. While large differences exist in the perceptions of the communication problems, both the Saudi Arabians and the Americans targeted differences in the patterns for organizing ideas as a major intercultural problem. Implications for intercultural training are provided.  相似文献

A selective amplifier is developed which is simple, and more flexible than other types. It utilizes an audio transformer with a variable series resistance in the primary circuit, and a variable secondary load capacitance both of which may be adjusted to give broad or narrow peaked amplification at any frequency within a wide range, or flat amplification throughout this range. Theoretical and experimental amplification curves are shown, and a transient solution gives the primary and secondary currents resulting when a voltage is suddenly applied to the amplifier. This analysis shows that the time constants for the circuit are comparable with those for other peaked amplifiers. Oscillograms are shown illustrating the transient behavior of the amplifier.  相似文献

Human stones     
Stones occur in several parts of the human body—kidneys, bladder, prostate gland, gallbladder, salivary glands, pancreas. Although not regarded as life-threatening, they can be a source of considerable pain and discomfort. The world-wide occurrence of the various types of stone is such that many people are likely to be affected at one time or another, either directly or indirectly.  相似文献
