Groundstone plummets of magnetite or hematite are commonly found artifacts of the Late Archaic period in Louisiana. While often assumed to have functioned as weights for fishnets or as thrown objects used to catch waterfowl, relatively little empirical evidence has been generated to explain their form and features relative to hypothesized performance in prehistoric behavior. To address this deficiency, we provide a morphometric analysis of the variability in plummet shape as a means for studying the performance constraints inherent to their use. Based on our analyses, we find that plummet form is well explained as a component of weighted looms, supporting the early use weaving technology in the Late Archaic of Eastern North America. 相似文献

Carbon and nitrogen isotope analysis was undertaken on collagen extracted from eel bone from six Mesolithic and Neolithic sites in northern Europe. The results were compared with data obtained on other archaeological fish remains and modern eel caught in fresh and brackish water and from the sea. The possibility of discriminating between freshwater, brackish and marine signals in archaeological eel bone is evaluated and the implications for archaeology discussed. Our data suggest that eel found at coastal Mesolithic and Neolithic sites have carbon isotope signals consistent with a marine origin with no evidence of freshwater residency. The sample of eel bone from one inland site is small but indicates carbon isotope values more consistent with freshwater residency or at least values intermediate between freshwater and marine carbon pools. 相似文献

Re-visiting the controversy caused by the first female-authored report in the Transactions of the Geological Society, this article probes the gendered layers of the early nineteenth-century scientific community. Maria Graham's ‘Account of Some Effects of the Late Earthquakes in Chili [sic]’ (1824) had considerable influence, and was referred to by Charles Lyell and Charles Darwin. In 1834, however, George Greenough, President of the Geological Society, questioned the accuracy of Graham's observations. Graham in turn defended herself adroitly, in an acrimonious exchange which found an international audience. While this dispute has received some attention from historians of science, previous discussions assume that Graham was no geologist, but simply a traveller who witnessed events of great relevance to contemporary geology. Drawing on extensive archival research, this article demonstrates to the contrary that Graham had considerable interest and expertise in this branch of science. Using the dispute to shed light on the multiple milieux in which early nineteenth-century science took place, it explores the constraints and opportunities faced by women with scientific interests, and the rhetorical strategies required of them, as they negotiated the diverse modes of contemporary science. It also highlights little-known networks of friendship, correspondence and intellectual exchange between scientifically minded women. 相似文献

This paper argues that the Indonesia–Malaysia–Singapore Growth Triangle makes manifest the complex geographies of power that subvert efforts to read cross-border regionalization as a straightforward geographical corollary of 'globalization'. As such, the region needs to be examined not simply as a complementary transborder assemblage of land, labour and capital, but rather as a palimpsest in which the imagined geographies of cross-border development and the economic geographies of their uneven spatial fixing on the ground are mediated by complex cultural and political geographies. We seek to unpack these by triangulating how the geographies of capital (including its uneven development and its links to the geo-economics of intra-regional competition), land (including post-colonial relations across the region, the geopolitics of land reclamation and the enclaved landscapes of tourism) and labour (including the divergent itineraries of migrant workers) overlay and complicate one another in the region. By charting these complex triangulations of space and place, we seek to problematize narratives of the Growth Triangle as an exemplary embodiment of the 'borderless world'. 相似文献

A Critical Comment on the Taylor Approach for Measuring World City Interlock Linkages 总被引:1,自引:0,他引:1
Carl Nordlund 《Geographical analysis》2004,36(3):290-296
In the study of economic‐geographic structures, the shifting focus from the national state to the city and its region has highlighted the lack of reliable interurban data sets. The abundance of usable data sets on international structures and flows has no counterpart when studying interurban relations, which makes it hard to draw any extensive conclusions regarding the structure of world city networks. Instead of relying on available data sets, Peter Taylor has developed a method for generating data sets that, it is argued, can be used in research on the structure of the world city network. In this approach, actors are defined as cities with internal attribute service values, values reflecting the presence of different transnational service‐producing corporations in each city. The structural values between each pair of cities are then established by a mathematical formula based on the service value of each firm in each pair of cities. This procedure can be criticized on two accounts. First, although internal attributes on exceptional occasions can be used as a proxy and as a rough estimate for structural values, such studies must have a firm theoretical underpinning in order to be valid from a network‐analytical perspective. If not, such generated structural values become nothing more than a function of internal attributes, thus losing the whole basic idea of social network analysis. Second, the Taylor function used for generating structural values can be questioned. Why should a large presence of TNC offices in a pair of cities imply a larger city interlock link than would be the case between a high‐ranked city and a low‐ranked city, as the city with the larger service value probably serves cities with a lower service value with economic command, control, and support functions? 相似文献

This study examines resinous deposits from the interior surfaces of sherds of imported Canaanite amphorae and locally produced bowls from the 18th Dynasty site of Tell el‐Amarna, Egypt. Archaeological evidence indicates that the Canaanite amphorae were used for resin transport, whilst the bowls are associated with burning resin as incense. A number of characteristic triterpenoids identify all the resinous deposits from both vessel types as Pistacia spp. No other resins were observed and there was no evidence of mixing with oils or fats. The composition of the archaeological resins is more complex than that of modern pistacia resin, due to degradation and generation of new components. Experimental heating alters the relative abundance of the triterpenoid composition of modern pistacia resin. One component, the triterpenoid 28‐norolean‐17‐en‐3‐one, is produced by such heating; however, an increase in its relative abundance in ancient samples is not matched by the archaeological evidence for heating. It is therefore not possible to use this component reliably to identify heated resin. However, additional unidentified components with a mass spectral base peak at m/z 453 have been associated with seven (out of 10) bowls and are not observed in resins associated with Canaanite amphorae. It is proposed that these components are more reliable molecular indicators of heating. 相似文献
