The Determinants of Regional Sourcing by Multinational Manufacturing Firms: Evidence from Yorkshire and Humberside,UK

An examination of the factors influencing the extent of regional sourcing by multinational manufacturing firms using data collected by interview from 50 foreign- and UK-owned plants in Yorkshire and Humberside. The evidence shows that higher levels of regional sourcing are observed where certain demand characteristics coincide with strengths in the supply potential of the region. A 'corporate filter' reduces regional sourcing. There were no differences in regional sourcing between foreign- and UK-owned multinationals. The findings identify barriers to policy aspirations of increased regional sourcing and emphasize that any policy initiatives should target the plants of domestic, as well as foreign, multinational enterprises (MNE).     

原始瓷的三种年代测定方法结果比较

采用常规的热释光细粒混合矿物法、热释光前剂量饱和指数法以及单片再生剂量光释光法三种测年方法,对中国上海、浙江萧山地区出土的7件西周、春秋、战国以及汉代的原始瓷样品进行了年代测定,并对测得的每个样品的3个年代结果与已知年代进行比对。用热释光细粒混合矿物法测定得到了较为理想的年代结果,与样品的已知年代结果相比吻合得较好。用热释光前剂量饱和指数法测定得到了该方法的上限饱和年代,即距今1800年左右。用再生剂量光释光法测定得到了这些样品的年代,只是实际年代的50％-80％左右,结果不太理想。因此,采用热释光细粒混合矿物法测定这类样品的年代,只要解决了制样问题,还是目前较好的测年方法。     

SOCIAL DYNAMICS ON THE NORTHERN FRONTIER OF ROMAN BRITAIN

Summary.   Despite much work on the frontier of Roman Britain, major questions concerned with society and settlement archaeology remain underinvestigated. Salient details of two major urban sites, Carlisle and Corbridge, both of which may shed further light on processes of settlement growth and decline, and which may ultimately contribute to a greater understanding of how the frontier worked, are summarized. At Carlisle, and probably also at Corbridge, settlement growth associated with forts was rapid and multi-tracked, but from the later second century AD changes took place associated, perhaps, with enhanced status and a growing sense of community.     

POST BUILT STRUCTURES AT DANEBURY HILLFORT AN ANALYTICAL SEARCH METHOD WITH STATISTICAL DISCUSSION

Summary. A computerised search method is described to identify every possible rectangular structure within set parameters from post hole distributions. Results are obtained from a dense distribution within Danebury hillfort and tested statistically by comparison with results from simulations and a mathematical model. The most likely structures are isolated by analyses of size, shape and orientation. A further comparison, with the results of an independent visual analysis of the same area, allows some comment to be made on the efficiency of human pattern perception and the validity of existing preconceptions concerning rectangular post-built structures.
