Pre-Columbian jadeitite artifacts from the Golden Rock Site,St. Eustatius,Lesser Antilles,with special reference to jadeitite artifacts from Elliot's,Antigua: implications for potential source regions and long-distance exchange networks in the Greater Caribbean

A detailed electron microscopy analysis of jadeitite celts from the Early Ceramic Age Golden Rock settlement on the small volcanic island of St Eustatius, Lesser Antilles, is presented in an effort to identify the source region(s) of these jadeitite axes and evaluate the extent of trade networks in the Caribbean during pre-Columbian times through which those tools (or source rocks) circulated. Habitation at the site occurred between ca. AD 230–890, and the jadeitite tools most likely date between cal. AD 600 and 825/890. We argue that in provenancing jadeitite emphasis should be placed on the identification of the entire mineral assemblage (including the accessory minerals) and textures, given the complex geological histories and processes that form this quasi-monomineralic rock. Indeed, the mineral assemblages and the characteristics of the individual minerals within the studied jadeitite samples are far from homogenous, suggesting either the source has a high degree of internal variation or there are multiple sources. We have identified three jadeitite groups among the analyzed samples on the basis of mineralogical assemblages: Group 1 consists of samples bearing phlogopite (plus phengite and epidote but without lawsonite or quartz); Group 2 contains lawsonite (plus phengite and quartz but without phlogopite and epidote); and Group 3 is defined by containing hematite. Importantly, we have not identified glaucophane in the analyzed materials. The comparison of these artifact data with those of jadeitites from the four potential known source regions of Caribbean jade, i.e., Guatemala (North and South Motagua Fault mélanges), Cuba (Sierra del Convento mélange) and Dominican Republic (Río San Juan complex) allows us to conclude that both the North and South Motagua Valley mélanges are the most likely sources for artifact groups 2 and 3, and perhaps also for group 1. This identification supports earlier hypotheses on the existence of pan-regional exchange networks, tying the northern Antilles with the Isthmo-Colombian region (Colombia, Panama and Costa Rica) during the Ceramic Age of the Caribbean.     

Late Pleistocene mammalian extinctions in North America: Taxonomy,chronology, and explanations

Toward the end of the Pleistocene, North America lost some 35 genera of mammals. It has long been assumed that all or virtually all of the extinctions occurred between 12,000 and 10,000 years ago, but detailed analyses of the radiocarbon chronology provide little support for this assumption, which seems to have been widely accepted because of the kinds of explanations felt most likely to account for the extinctions in the first place. Approaches that attribute the losses to human predation depend almost entirely on the assumed synchroneity between the extinctions and the onset of large mammal hunting by North American peoples. The fact that only two of the extinct genera have been found in a convincing kill context presents an overwhelming problem for this approach. Climatic models, on the other hand, are becoming increasingly precise and account for a wide variety of apparently synchronous biogeographic events. While a role for human activities in the extinction of some taxa is fully possible, there can be little doubt that the underlying cause of the extinctions lies in massive climatic change.

Computer-based,automatic recording and illustration of complex archaeological artifacts

We report on the development of a computerized automatic system to illustrate complex archaeological objects. The illustrations are based on 3D scans of the artifacts. The 3D models can be automatically translated, by new algorithms specifically designed for this purpose, into 3D or 2D line drawings; into colored images that emphasize the salient shape attributes of the artifacts and of the 3D designs on them; and to images that enhance faint/eroded designs that are otherwise difficult to discern. These illustrations are intended to replace traditional, manual drawings, which are very expensive to produce and not accurate enough. Our illustrations also provide a better visualization tool than the 3D models themselves. Though 3D scanning already improves the visibility of objects and their features, it does not suffice for rapid visual recognition. Our system generates efficient, objective, accurate and simplified representations of complex objects and the designs on them from any number of required views.     

From humanitarian relief to humanitarian intervention: victims, interveners and pillars

Current humanitarian crises are bedeviling the United Nations, relief agencies and governments. Efforts to provide food and other basic supplies to traumatized populations are frequently stymied by uncooperative regimes, violent militias, remote locations, high costs and complicated operations. As a result, humanitarian relief operations that have focused primarily on food distribution must be radically revised to encompass the much broader agenda of humanitarian intervention, which entails an aggressive, multilateral role within states. Five ‘pillars’ are proposed—basic needs, public security, political dialogue, human rights/justice and sustained economic development—on which to base future humanitarian interventions.     

The Broad Spectrum Revolution at 40: Resource diversity,intensification, and an alternative to optimal foraging explanations

More than 40 years ago Kent Flannery coined the term Broad Spectrum Revolution (BSR) in reference to a broadening of the subsistence base of Late Pleistocene hunter–gatherers in the Near East that preceded and helped pave the way for the domestication and plants and animals and the emergence of agriculture. Set within a demographic density model that projected differential rates of population growth and emigration in different resource zones of the Near East, Flannery’s BSR quickly became a global construct linking resource diversification and intensification to imbalances between population and environmental carrying capacity. In recent years the BSR has proven especially attractive to researchers working within an optimal foraging theory (OFT) framework in which diversification and intensification of subsistence only occurs within the context of resource depression, caused by either demographic pressure or environmental deterioration. This OFT perspective, that situates human societies in a one-way adaptive framework as they are forced to adapt to declining availability of optimal resources, however, is increasingly being called into question. Numerous examples of diversification and intensification are being documented in contexts of resource abundance shaped, in part, by deliberate human efforts at ecosystem engineering intended to promote resource productivity. An alternative approach, framed within a newer paradigm from evolutionary biology, niche construction theory (NCT), provides a more powerful explanatory framework for the BSR wherever it occurred.     

Post-depositional surface whitening of ceramic artifacts: alteration mechanisms and consequences

Surfaces on ceramic artifacts that are paler than the main sherd body are commonly interpreted as slips that were intentionally applied by the potter during the manufacturing process. However, due to post-depositional alteration, sherds that were not originally coated with a slip may macroscopically appear with deceptively similar pale surfaces. This paper presents a comparison of two sherds, both with pale to white surfaces, one of which is a real slip and the other a surficial corrosion that occurred during the burial stage. Observations using optical and scanning electron microscopy, as well as electron-probe image- and microanalysis, clearly illustrate the features of the two surfaces, as well as demonstrating their causes and effects. The superimposed slip is clearly delimited from the sherd body by a denser and much finer-grained fabric, in which clay minerals predominate and porosity is reduced by about 20% compared to the body. In the other sample, surface corrosion, due to invading fluids, has led to leaching of calcareous constituents and results in a remarkable increase in porosity close to the rim (ca. 25%). Sometimes called the “espresso crema effect” (Tschegg et al., 2009b), the surface becomes considerably brighter than the core and can easily be confused with intentional slips. This, as a consequence can lead to significant misinterpretations, to erroneous sherd characterizations and classifications, as well as to incorrect assignments to specific ware groups.     

Cross-cultural interaction on Wuvulu Island,Papua New Guinea: the perspective from use-wear and residue analyses of turtle bone artifacts

Recent studies have emphasized the importance of Indigenous producers and traders in the formation of ethnographic museum collections, but have found difficulty in finding concrete evidence for their active roles. A use-wear and residue study of turtle bone cleavers from Wuvulu Island, Papua New Guinea provides the opportunity to test whether objects that comprise a significant component of early collections were made specifically for sale, as hypothesized by contemporary observers in the late 19th century. Comparative studies of used and unused turtle bone artifacts from the Caroline Islands and Papua New Guinea identified differences between wear traces resulting from manufacture and use. Analyses of the Wuvulu turtle bone cleavers showed they had been heavily used prior to sale. Rather than produce artifacts to meet the high demand from German traders, the local people sold old, worn-out objects, many of which had been repaired. The study demonstrates that archaeological approaches to ethnographic museum collections can trace Indigenous agency within cross-cultural interaction. It also showcases the potential of use-wear and residue analytical techniques for the analysis of bone tools and the utility of digital, hand-held microscopes for the analysis of large artifacts.

Understanding China's regional rise: interpretations, identities and implications

The literature on China's regional rise reveals divergent understandings of why China changed its regional strategy and when such a transformation occurred. There are also different understandings of the extent of China's power in the region—or more often, the extent to which US power in East Asia is already challenged by China's regional rise. Nevertheless, there is a consensus of sorts over how Chinese policy has changed with an emphasis on a combination of proactive diplomatic initiatives and ever increasing economic interactions. After providing a brief overview of the existing literature, the main part of this article considers the role of China's 'soft power' in reconfiguring power relationships in East Asia. It suggests that while the US might have lost some of its ideational appeal, it is through working within existing frameworks and 'norms' (rather than establishing new revisionist alternatives) that China has had most success in assuaging fears of the consequences of its rise. However, the way in which others conceive of China's rise and Chinese power (and subsequently act) does provide a form of 'non-hard' power that might help China's leaders attain their regional objectives particularly in light of the continuing global economic crisis.     

The South Korean financial crisis: competing explanations and policy lessons for financial liberalization

There are two types of explanations of the Asian financial crisis: the 'fundamentalist', which focuses on macroeconomic imbalances; and the 'self-fulfilling', which ascribes the crisis to beliefs. This article argues that while both have some merit in explaining the Korean crisis, neither fits the facts very well. The authors put forward a new explanation which emphasizes the role played by financial liberalization and the structural weaknesses in the banking system. They explain that the combination of these factors created conditions that made the Korean banking system vulnerable to the sentiments of foreign investors, simultaneously eroding the ability of the Korean central bank to act effectively as a lender of last resort. The authors examine how various policy mistakes aggravated the crisis and draw some conclusions that may be useful for other emerging market economies.     

Museum salvage: A case study of Mesoamerican artifacts in museum collections and on the antiquities market

Abstract

Museum salvage refers to critical studies of museum collections with little or no provenience information that seek to glean useful archaeological information from these artifacts and examine the nature of their origins and possible connections to the illicit antiquities trade and the art market. Our case study focuses on artifacts from Mesoamerica and objects from the ancient capital of Teotihuacan in particular. We take a multi-scalar approach, including a quantitative analysis of Sotheby’s auction records for Mesoamerican items from 1966 to 2010, a survey of Teotihuacan attributed items in U.S. museums, and a more detailed examination of Teotihuacan-style artifacts in the Denver Museum of Nature & Science collections. The study tracks and attempts to explain diachronic patterns in the Mesoamerican antiquities trade, connections to museum collecting practices, and looting behavior. The study illustrates the potential benefits of museum salvage, while also revealing the clear limitations of research on poorly documented archaeological material.
