The main findings of this analysis of the job location patterns by occupational groups in the Toronto CMA are as follows:
  • 1 The geographical distribution ofjobs of the different occupational groups varied considerably in the Toronto CMA, the principal pattern being relative centralization of white-collar jobs and relative decentralization of blue-collar jobs. Skilled clerical-sales-services workers faced the greatest degree ofjob concentration in the cbd.
  • 2 The jobs of similar occupational groups by collar type were located near one another, so that relatively homogeneous work areas were created. These conclusions, of course, apply specifically to the Toronto CMA in 197 1. But, although the urban structure of the Toronto CMA will have changed to some extent since 1971, the process of structural change is a fairly slow one, even in rapidly growing metropolitan areas. We suggest, therefore, that our findings should be relevant to the Toronto CMA of today.

Yelang (夜郎), a mysterious state located in the south‐western area of early China and dating from the Bronze Age to the Early Iron Age (1300 bc – ad 25), is a cultural interactive junction between the Yunnan–Guizhou Plateau and the Yangtze River Basin. The Zhongshui Basin in Weining County, Guizhou Province, was one of the important distribution areas of the Yelang civilization. This area, which includes sites at Jigongshan (鸡公山; 1300 – 800 bc ), Hongyingpan (红营盘; 700 – 400 bc ) and Yinzitan (银子坛; 400 bc – ad 25), has provided a very integrated chronology, spanning from the Bronze Age to the Early Iron Age in the eastern Yunnan – western Guizhou area. To investigate human migration and horse‐trading at these Yelang sites, we conducted a strontium isotopic analysis on the teeth enamel of humans and horses unearthed from these three sites. The results indicated the following: (1) people at the earlier sites (Jigongshan and Hongyingpan) were all indigenous, whereas in the Yinzitan cemetery, there was a more immigrant population, and all the people who were buried in an upper limb flexed supine position were non‐local; and (2) most of the horses found at the Jigongshan and Yinzitan sites show different provenances, probably related to the famous Dian (滇) and Zuo (筰) horses recorded in historical documents, providing more clues for further study on horse‐trading in South‐West China during the Bronze Age and the Early Iron Age.  相似文献
