Two traditional Jewish approaches to the location of synagogues can be found, one symbolic and one functional. The locational requirements are not identical; the symbolic approach deals with idealistic spatial status while the functional approach poses realistic locational demands. This spatio-locational conflict reflects a problematic situation on both theoretical and practical levels.  相似文献

This research first develops a paradigm relating technology adoption, plant function, and location in different areas. It then examines empirically some of the paradigm's postulates dealing with occupation staffing patterns and wage rates in headquarters and production plants in different size cities and regions of the country using survey data. The research found that plants in large cities, headquarters plants, and plants in innovative regions paid higher wages than plants in small cities, production plants, and those in innovation-lagging regions. Headquarters plants and plants in large cities and innovative regions had a significantly larger number of scientists, engineers, and technicians on their staffs but few production workers. Production plants and those in small cities and towns and lagging regions had few professional workers but a significant number of production workers. For all types of plants an inverse relationship existed between plant size and city size. The postulated direct relationship between plant size and wage rates was not clearly evident in the survey data except for low skilled occupations. Neither was the relationship clearly evident in the U.S. Census data for the computer and semiconductor industries, as it was for total U.S. manufacturing.  相似文献

金字塔沙丘以其大尺度、金字塔形态和放射状伸展的沙臂为特征。本文以三面体金字塔沙丘模型的风洞流场实验为基础,结合野外观测资料,发现金字塔沙丘的流场结构,特别是背风侧剖面流场除具有一般新月形沙丘的流场结构特点外,还有特殊的"E"型流场结构,正是这种多向风信产生的复杂流场结构形成具有凹面形态的多角形金字塔沙丘。据此,作者提出了由新月形沙丘(包括其复合形态)演化为金字塔沙丘的发育模式。  相似文献
