The ancient names huangniao, canggeng and several related terms, usually thought to represent the oriole, appear in Zhou and Han texts, for example in Shijing, Erya, Shanhaijing, and various commentaries. The present article comments on these names. It shows that there was an early stage in which a difference was made between canggeng and huangniao, while in later times, from the Han period onwards, these distinctions gradually disappeared. The article also suggests that, originally, canggeng probably stood for Oriolus chinensis, i.e., the black-naped oriole, while huangniao may have meant several other birds; later on, however, all terms were used for O. chinensis.  相似文献

Subsurface sampling programs are regularly employed to detect buried archaeological material in open landscapes. Rarely, however, is the effectiveness of the sampling program assessed through subsequent excavation. Here, an optimal subsurface testing strategy is designed using Kintigh’s simulation approach to locate prehistoric knapping floors and is applied to an open landscape in southeastern Australia. Several prehistoric knapping floors were discovered using this strategy and nine of these were subsequently excavated to establish their diameters, densities, and density distributions. The results indicate that there is a high level of divergence between test-pitting data and excavation data. This demonstrates that test-pit data cannot be assumed to provide an accurate representation of site characteristics. It follows that an empirical validation of site characteristics through subsequent excavation is needed before a meaningful evaluation of the effectiveness of a sampling strategy can be conducted.  相似文献

Central Cities as Engines of Metropolitan Area Growth*   总被引:1,自引:0,他引:1  
The paper analyzes the role of central cities as engines of economic growth in their metropolitan area. We wonder if there are increasing returns to central city growth at the metropolitan level arising from the positive externalities associated with the unique features of central cities. To answer this question we analyze the causality between the economic growth of Spanish central cities and the growth of the other jurisdictions belonging to their metropolitan area (i.e., the suburbs). The analysis uses population and economic activity data for a sample of 28 Spanish metropolitan areas during 35 years. We use a Vector Error Correction Model (VECM) framework to estimate long‐run equilibrium relationships between the growth of central cities and their suburbs. The combination of panel data and a VECM is an innovative approach that is still being developed in econometrics. The results suggest that central city growth has a long‐run positive effect on the growth of the suburbs. We also inquire as to whether or not this positive effect depends on the size of the central city. The results suggest that the effect is much higher in the case of the largest cities, but that it is also important in the case of the smaller ones.  相似文献

The article sets out to map militant Soviet solidarity with the Republicans during the Spanish Civil War (1936–9). It is based on recently declassified letters that ordinary Soviet citizens addressed to the Comintern, asking its head, Georgi Dimitrov, to send them as volunteers to fight against Fascism in Spain. The articles evaluates the social profiles of these would-be volunteers, their rhetoric of militant solidarity and the social climate in which they formulated their pleas to fight abroad – namely the onset of Stalin's purges in the Soviet Union.  相似文献
