We present a series of iterative methods to examine the problems associated with summed probability functions (SPFs) based on archaeological radiocarbon data. As a case study we use an SPF generated from a substantial radiocarbon data-set from the Irish Later Bronze and Iron Ages. We use simple numerical methods to show that real patterns can be deciphered from SPFs that can be used to trace and evaluate patterns of change. However, our results suggest that SPFs should not be used as a simple index of past human activity. 相似文献

Existing insights into the history of southeast Asian contacts with northern Australia prior to British colonization in 1788 are limited to Macassan visitors and the trepang industry beginning in the early 18th century and perhaps 16th century. Neither historical nor archaeological evidence indicate extension of such contacts to Torres Strait of northeast Australia. To shed further light on this issue, a collection of 16 Asian ceramic sherds surface collected and excavated recently from the islands of Pulu and Mabuyag in Torres Strait were compared to a large database of Southeast and East Asian stoneware jars that are well characterised, elementally, typologically and chronologically. This comparison matched a number of sherds with two jar types with likely production origins in Thailand and southern China. While the surface collected sherds from Pulu sourced to Thailand date probably to the 19th century, the small glazed sherd from Mabuyag island is typical of a southern Chinese decorated jar type dating to c. 1500–1600 C.E. This Chinese sherd is the earliest known Asian artefact in Australia and parallels recent archaeological evidence on the antiquity of contacts between Macassan trepangers and Aboriginal Australians. It is unknown if the Chinese sherd came ashore to Mabuyag through direct contact with Asian traders or from a nearby shipwreck through salvage. 相似文献

On 9 February 1947, a detachment of armed police was called into the Insein Central Gaol in the northern suburbs of Rangoon to quell a serious disturbance. The police fired into the rioting prison wards, killing four inmates—a further prisoner died of heart failure—and wounding three others. The inspector-general of prisons, Burma, the superintendent of the Insein Gaol, and the district superintendent of police were subsequently suspended from duty. This paper examines the background to the Insein Gaol shootings, the incident itself, the government-ordered enquiry into the shootings, the government's response to the enquiry's report, and the final fate of the three senior prison and police officials. The paper sets the Insein prison shootings, in all their aspects, in the context of the fierce struggle between the Burmese nationalists and a weakening British administration in the final months of colonial rule. 相似文献

Wang, G., Percival, I.G. & Li, R., 25.2.2015. Remarks on the pattern of septal insertion in rugose corals. Alcheringa 39, xxx–xxx. ISSN 0311-5518Well-preserved specimens of the Hirnantian (latest Ordovician) rugose coral Lambeophyllum? corniculum He from the Yangtze Platform of South China, clearly show how catasepta (minor septa) are inserted, confirming the model proposed by Weyer in the 1970s. Our observations indicate the insertion of counter lateral septa and their neighbouring catasepta on the counter side takes place in exactly the same manner as that of the subsequent metasepta and catasepta. We propose abandoning the use of the term counter lateral septa. Therefore, exclusion of the pair of counter lateral septa reduces the number of protosepta from six to four.Guangxu Wang [gxwang@nigpas. ac. cn], State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (CAS), 39 East Beijing Road, Nanjing 210008, PR China; Ian G.

Analysis of the pre‐disturbance values of the in situ corrosion parameters on historic iron shipwrecks and artefacts has established that the arithmetic product of the pH and corrosion potential is dependent on the burial environment and provides a unique insight into the objects' state of decay. The value of the product changes during in situ conservation treatment with sacrificial anodes, and reaches a minimum at which point the treatment is completed. Treatment times vary with water‐depth, being faster on shallower sites and shorter for more extensively corroded artefacts. The model was developed using data from the Duart Point wreck (1653), the Monitor‐styled warship HMVS Cerberus (1926) and a series of wrecks in Australia and the USA. 相似文献

Increasingly, archaeologists are opting for on-site examination, reinterment, and in situ preservation of underwater cultural heritage sites as the first option in the management of sites at risk, as opposed to the more traditional excavation, recovery, conservation, and display/storage methods. This decision will inevitably be based on significance assessment, degree of perceived risk, and resourcing issues. However, long-term monitoring must become an integral part of these management programmes in order to quantitatively evaluate the effectiveness of the in situ preservation techniques employed. In 2012 the Australian Historic Shipwreck Preservation Project (AHSPP) was awarded a large Australian Research Council (ARC) Linkage Grant, enabling ten partner organizations and three Australian universities to collaborate in one of the largest multi-organizational maritime archaeology projects to be undertaken in Australia to date. One of the major aims of the project is to develop a protocol for the excavation, detailed recording and reburial of significant shipwrecks under threat, fostering a strategic national approach for the management of underwater cultural heritage (UCH) sites at risk. Two historically significant shipwreck sites that are considered under threat were chosen for this longitudinal comparative study — the Clarence (1850) located in Port Phillip Bay, Victoria; and the James Matthews (1841) which lies in Cockburn Sound, Western Australia. Both sites have been preserved in situ using two very different but innovative remediation strategies. More importantly, long-term monitoring programmes have been implemented on both sites, which will characterize changes in the reburial environment and the effect on the reinterred materials. In this way, the efficacy of both in situ preservation techniques will be systematically tested, providing a comparative analysis of practical protocols for the long-term protection and management of underwater cultural heritage. 相似文献

Like many other advanced industrial democracies, Australia has experienced major and ongoing economic reform over the last two decades, the pace of which has, if anything, increased since the election of the Liberal‐National government in 1996. These developments have led to a growing sense of economic insecurity among many voters. Many of these concerns were focused on the 1998 election, when the Liberal‐National Coalition advocated the introduction of a goods and services tax. This paper uses the 1998 Australian Election Study (AES) survey to examine the impact of economic evaluations, economic insecurity and economic issues on voting in the election. The results demonstrate the existence of widespread economic concerns across the electorate, but that the Coalition gained a marginal electoral advantage on the tax reform issue. Economic issues were also a cause of defection to the new One Nation Party, although further analysis reveals that its support was motivated more by race and ethnic concerns than by economic discontent. 相似文献
