While most historians have discussed corruption as a key factor leading to South Vietnam's downfall, they have not fully analysed the US and international dimensions of South Vietnamese corruption. This article argues that economic, political, and diplomatic circumstances of the Vietnam War encouraged widespread US participation in currency manipulation, an economically destructive form of corruption that had serious implications for the stability of the South Vietnamese state. The US inability to shape South Vietnam's setting of the official exchange rate allowed South Vietnam to overvalue the piaster at the cost of US taxpayers. Combined with the structural economic problems produced by the war, such as inflation, the favourable exchange rate encouraged Americans, Vietnamese, Indians, Chinese, Koreans, and other internationals to make quick profits through illegal transactions. From bookstores in Saigon to banks in Hong Kong, Dubai, and New York, currency manipulation involved a host of individuals and organisations around the globe. Although many critics of the war cited South Vietnamese corruption in their arguments for US withdrawal, congressional investigation into currency manipulation revealed that without the direct contributions of US soldiers and civilians, the magnitude of illegal economic transactions would not have existed as it did.  相似文献

The terms Lower Palaeolithic and Middle Palaeolithic represent research constructs within which cultural evolution and prehistoric hominin behaviours can be studied, with the transition usually understood as marking a watershed in our evolution: an adaptation with a million-year record of success that gives way to something new. The interpretation of the Lower Palaeolithic Acheulian technocomplex is usually understood as a period of cultural stasis that extends over much of Africa and Eurasia, principally associated with Homo erectus. Those innovations that can be observed occur widely separated from one another in space and time. Yet a closer and more detailed examination of the Middle Pleistocene records from East Africa, southern Africa, Europe and the Levant reveals significant variation in cultural repertoires. A kind of paradox emerges, in which an Old World Lower Palaeolithic, apparently lacking an overall dynamic of distinctive and directed change in terms of cumulative variation over time, nevertheless culminates in a transition which sees the universal appearance of the Middle Palaeolithic. The two main hypotheses that have been advanced to explain the global transition, which happens essentially synchronously, appear mutually exclusive and contradictory. One view is that altered climatic-environmental constraints enabled and encouraged an ‘Out-of-Africa’ dispersal (or dispersals) of a new type of genus Homo. This cultural replacement model has been challenged more recently by the alternative hypothesis of accumulating but unrelated and temporally non-linked regional, and in fact potentially autochthonous, processes. The Levant, by virtue of its position bridging Africa and Eurasia (thus being the region into which any out-of-Africa groups would have had first to disperse into), must be seen as a critical region for assessing the relative merits of these competing hypotheses. This paper deals with the Lower–Middle Paleolithic boundary in the Levant within a long temporal perspective. The Middle Pleistocene record in the Levant enables us to examine the amplitude of variation within each techno-complex, as well as to question whether there are diachronic changes in the amplitude of techno-typological variations as well as changes in the manner by which they appear in the record. The results carry significant implications for understandings of demographic and societal processes during the Lower–Middle Paleolithic transition in the Levant.  相似文献

Understanding how archaeological sites are abandoned is a vital part of archaeology. This paper explores abandonment as a phenomenon in a worldwide context, particularly in relation to sites with evidence of fire, and with a special focus on the South-Central Andes. I evaluate the patterns from an area of the Argentinian Andes and discuss the disappearance of the Aguada Culture, one of the central cultures in Argentinian prehistory, using evidence from the core area the Ambato Valley. I conclude that environmental factors were not the sole or determining source of stress, but rather part of a social–environmental dimension in which several factors combined to push a society into a vulnerable situation. In terms of the abandonment of the Aguada settlements in the Ambato Valley, the study shows that frequent forest fires might have played a role, but based upon the regularity of such events as seen in the sediment history, it is unlikely that these were the only factor in the process of abandonment of the valley.  相似文献

Recently found open-air flint extraction and workshop sites in the Eastern Galilee, Israel, are the focus of this paper. Lithic assemblages from among a few of the thousands of tailing piles documented in a field survey, indicate mostly late Lower Palaeolithic/Middle Palaeolithic and rarely Neolithic/Chalcolithic affinities. These discoveries substantially increase our knowledge of the scope of lithic extraction and reduction in northern Israel in these periods. The new sites are located on a 25 km2 outcrop of flint-bearing Eocene limestone indicating intensive extraction of large amounts of flint, possibly beyond immediate local consumption requirements. After describing the new sites, we discuss their relation to nearby Middle and Lower Palaeolithic sites; possible resource management scenarios; chronology and duration of the extraction and reduction activity; and the sites as possible landmarks. A key question is the extent of the flint distribution area, or, more precisely, whether this region was a dominant mega-quarry for northern Israel and/or Southern Lebanon in the periods discussed.  相似文献

Occipital bone lesions on an Iron Age horse cranium from the burial mound of Arzhan 1, Tuva, Central Asia, are described and interpreted. Cavitations around the nuchal ligament attachment site on the skull are interpreted as foci of inflammation and necrosis following local infection. It is suggested that the pathology represents a case of ‘poll‐evil’, most likely due to a bacterial infection. The significance of such an interpretation is discussed, including its implications for disease ecology and the possible infection risks to contiguous animal and human communities of the first millennium BC in Central Asia.

The Archaeological Museum of Jaén's sizeable collection of Iron Age sculptures, dating from the fifth century bce , were all found at Cerrillo Blanco de Porcuna, a site in the Spanish province of Jaén. The collection comprises over 40 statues and hundreds of fragments. Incisions recently identified on some of these sculptures have been interpreted as sculptors' marks. The present archaeometric study, conducted with a 3D roughness meter, showed that the marks on several of the sculptures analysed were made with the same type of tool and the same engraving technique. While the graphological differences denote different authorship, they would appear to have been made in the same workshop. The morphological differences observed in the lines analysed on other sculptures are interpreted to indicate the use of other types of tools and engraving techniques.  相似文献

The enamels of the Altar of San Giovanni, from the Baptistery of Florence, were investigated using both non‐invasive and micro‐invasive analysis in order to elucidate the glass melting and colouring techniques. A few fragments detached from the altar and recovered by the restorers were analysed in cross‐section by electron probe microanalysis. Moreover, non‐invasive investigations by portable XRF allowed a large number of enamelled plaques to be investigated. The results showed a good agreement between the two techniques and made it possible to identify similarities or differences in the enamels of the three manufacturing periods of the altar.  相似文献

Stable oxygen isotopes from estuarine bivalve carbonate from Saxidomus gigantea were analysed combined with high‐resolution sclerochronology from modern and archaeological shells from British Columbia, Canada, to determine the seasonality of shellfish collection from the archaeological site of Namu. The combination of high‐resolution sclerochronology and a micro‐milled sampling strategy for δ18O analysis permits a precise estimate of archaeological seasonality, because seasonal freshwater influxes and changes in temperature have dual effects on the δ18O value of the shell. Sclerochronological analysis identifies the timing and duration of growth that is temporally aligned to stable oxygen isotope results, since δ18Oshell appears to be strongly influenced by seasonal inputs of very low δ18O snowmelt‐water from adjacent coastal mountain ranges. The results show that shellfish were collected year‐round at this site over a 4000‐year period, and these data combined with other zooarchaeological lines of evidence support the interpretation of year‐round occupation.  相似文献

Torres et al. (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp . This study uses the ultrafiltration pre‐treatment protocol to obtain a date of 48 400 ± 3200 bp (OxA‐21 776) on a bone fragment and confirm the antiquity of the Neanderthal assemblage. Moreover, it demonstrates the comparability of the ultrafiltration and ninhydrin bone radiocarbon pre‐treatment protocols, and highlights the need for appropriate screening methods where valuable collections with poor biomolecular preservation are sampled for collagen extraction.  相似文献

World‐renowned Renaissance astronomer Tycho Brahe died on 24 October 1601, after 11 days of illness. Several conspiracy theories regarding his death have been aired, the first shortly after his death by William Shakespeare in the play Hamlet, published in 1603. A key factor in the still lively debate is whether he was administered mercury—as medicine by his own hand, or as poison by an unfriendly hand. In 2010, Brahe's grave was reopened and samples of his bones, hair, teeth and the textiles were procured and analysed. Here, we present evidence that Brahe was not administered lethal doses of mercury.  相似文献
