Googling the Grey: Open Data,Web Services,and Semantics

Primary data, though an essential resource for supporting authoritative archaeological narratives, rarely enters the public record. Lack of primary data publication is also a major obstacle to cultural heritage preservation and the goals of cultural resource management (CRM). Moreover, access to primary data is key to contesting claims about the past and to the formulation of credible alternative interpretations. In response to these concerns, experimental systems have implemented a variety of strategies to support online publication of primary data. Online data dissemination can be a powerful tool to meet the needs of CRM professionals, establish better communication and collaborative ties with colleagues in academic settings, and encourage public engagement with the documented record of the past. This paper introduces the ArchaeoML standard and its implementation in the Open Context system. As will be discussed, the integration and online dissemination of primary data offer great opportunities for making archaeological knowledge creation more participatory and transparent. However, different strategies in this area involve important trade-offs, and all face complex conceptual, ethical, legal, and professional challenges.     

Guaranteeing the Protection of Submerged Archaeological Sites Regardless of their Location: The UNESCO Convention on the Protection of the Underwater Cultural Heritage (2001)

The UNESCO 2001 Convention on the Protection of the Underwater Cultural Heritage represents a significant move forward in the global protection and management of underwater cultural heritage. This paper reviews the Convention’s most basic tenets, such as in situ preservation, refusing commercial recovery, encouraging the cooperation of States also beyond territorial waters, and the creation of international standards for underwater archaeology. It also discusses the Scientific and Technical Advisory Body and highlights the Convention’s current status as an important tool to preserve and protect an international maritime heritage.     

Shopping with Karl: Commodity Fetishism and the Materiality of Marx’s London

Scholars have postulated that commodity fetishism represents Marx’s theory of capitalist materiality, but the content of that theory is contested. I offer an archaeology of Marx’s material world in order to understand the development of the concept. During his time in London, Marx wrote and published Capital: A Critique of Political Economy (1867), in which he outlined the concept of commodity fetishism. I demonstrate that he formed his analysis of commodity fetishism from daily practices including shopping, and consuming tobacco, in combination with his research at the British Museum. I take an experiential approach to archaeology that foregrounds Marx living in a world of objects, and posit a relationship between his experiences and his understanding of commodities. In so doing, I show how Marx’s “everyday life” shaped his concept of commodity fetishism, and how this concept could be useful to historical archaeologists.     

An Academic Perspective on Grey Literature

This article presents an academic’s perspective on grey literature, providing the viewpoint from someone who has experience publishing in both academic and grey literature venues. I explore the strengths and weaknesses of grey literature and argue that more rigorous quality control, increased access to this literature, and more scholarly cooperation are necessary in order for grey literature to become accepted as a legitimate published form.     

Temperature,compression and fragmentation: an experimental analysis to assess the impact of taphonomic processes on charcoal preservation

This paper explores how mechanical properties of different South Asian tree taxa might influence charred wood fragmentation and the composition of charcoal assemblages retrieved from archaeological contexts. The dataset is composed of selected plant species that were collected in Gujarat (Northern India) in September 2007 as part of the North Gujarat Archaeological Project. The taxa analysed represent the most common wood species found in the arid thorn scrubland formation in South Asia and are among the most abundant identified in Neolithic and Chalcolithic archaeological sites in this area. The specimens have been measured and subsequently charred at three different temperatures, under constant conditions. Afterwards, their resistance to compression has been measured on two planes, parallel and perpendicular to the direction of fibres, using a Hounsfield 5-kN machine. The tests were performed in order to understand the different response to compressive stress of wood that has been subject to a range of thermal degradations. The standardised treatment applied to the samples has permitted the comparison of results and the delineation of simple correlations and divergences among the species analysed. Furthermore, the utilisation of a relatively simple operating protocol easily allows the addition of further data in the future. The applied protocol was specifically designed to answer archaeological questions. Therefore, even though from a material science point of view some of the measurements were not taken according to the prevailing standard procedures, it offers valuable data for anthracological research applied to archaeology in arid zones.     

Characterisation of the raw metal sources used for the production of copper and copper-based objects with copper isotopes

Copper isotopes can be successfully used to determine the origin of copper or bronze artefacts from either primary or supergene sulphide or hydrocarbonate ores. In conjunction with lead isotopes, they provide information on the origin and type of the metal ore. We demonstrate this in this paper from the combination of literature and own data on metal ores and artefacts (coins and ingots). Low-temperature hydrocarbonates (esp. malachite and azurite) do not fractionate the copper isotopes amongst each other and have identical lead isotopes. Substantial fractionation of copper isotopes, however, occurs between copper sulphides and hydrocarbonates (malachite, azurite) such that the ⁶⁵Cu isotope is always enriched in the oxidised relative to the sulphide phase with a clear distinction between the two ore types. Expressed in the δ⁶⁵Cu notation, we assigned supergene sulphides to values less than −0.4‰ down to negative values of −2‰ and more, primary sulphides to a range between −0.4 and +0.3‰ and hydrocarbonates to positive values higher than +0.3‰. We have applied these boundaries to copper coins and ingots from the time of the Roman emperors with known ages from Augustus up to 250 AD. The deposit fields of the metal used for the production of the coins were previously identified from the lead isotope ratios to lie in the Southwest and the Central South of Spain. From the combination of the lead and copper isotopes and the exact time constrains, we could develop a picture of the change in mining activities in Spain involving continued mining sulphide ore deposits and, indicated by positive δ⁶⁵Cu values as proxies for malachite and azurite, the opening of new mines in various time slots. This first application shows that copper isotopes will become the most important tool in archaeometallurgy to distinguish between the exploitation of deeper-seated primary and supergene sulphide ores and shallower, secondary hydrocarbonate ores. This will become especially relevant for archaeometric questions regarding the distinction between occasional and intentionally produced alloys.     

新传统的兴起——晚明观念变迁与生活方式

Ethics based on Confucian moral virtues and guides as core values have long formed the “old tradition” in determining the direction of China’s social development. Changes of urban residents’ values and corresponding changes in life styles in late Ming Dynasty demonstrated the emergence of a new cultural tradition that advocated for human freedom and the development of individuality, material enjoyment and pleasures in life, and questioned and critiqued Confucian moral virtues and guides. Although such a cultural tradition had not yet matured, its humanist values made deep imprints in that period. This tradition survived despite of the successions of dynasties and vicissitudes of the ages, although from time to time it became so weak as on the verge of extinction. It was this continuous and unceasing cultural progress that later laid the primitive but essential cultural foundation for the start of China’s efforts to achieve modernization after the middle of the 19^th century.     

Rice archaeological remains and the possibility of DNA archaeology: examples from Yayoi and Heian periods of Northern Japan

Japanese rice cultivation in paddy fields has 2,400∼3,000 years of history. Most of modern Japanese rice varieties are classified as Temperate-japonica (Tm-J). Few landraces are recognized as Tropical-japonica (Tr-J) only in southwestern Japan. However, ancient DNA studies and phytolith analysis suggest that Tr-J strains were more popular in the past than now. Maekawa is a complex archaeological site composed of paddies dated from the Yayoi (2,100 years BP) to the Heian (1,100 years BP) periods. Phytolith analysis indicates that intensive rice cultivation was practiced in both periods, but there was no cultivation in the intervening period. Morphological features of bulliform phytoliths suggest that Tr-J was cultivated during both periods. Locally, rice cultivation during the Heian period was brought to a close by a flood event, in which immature rice plants were pulled down and buried in silt to be preserved in a quasi-carbonized/ waterlogged state. Ancient DNA (aDNA) analysis of the carbonized plant culm from Heian Maekawa recovered chloroplast DNA sequences of the 6C7A plastid subtype, which is common to both Tr-J and Tm-J, whereas two plastid subtypes, such as 6C7A and also 7C6A, were found in aDNA of carbonized grains from the Tareyanagi site of the Yayoi period. The latter plastid subtype was specific only to Tr-J. In order to better characterize the past rice populations, modern landraces collected in the local area were classified with morphophysiological traits. Some of the landraces were found to carry several traits of Tr-J, including bulliform phytolith types, but mixed with Tm-J traits. Based on the discontinuous distribution of rice phytoliths between the Yayoi and the Heian period, the early introduction of rice cultivation may have been discontinuous and locally reintroduced after a ∼1,000-year hiatus, but with a genetically different rice population. Such populations were composed from Tr-J like strains as shown by landraces but with reduced diversity in plastid types. Through such changes, since the Yayoi era, Tr-J was largely replaced by Tm-J, although ancient Tr-J continued to participate in the genetic makeup of later rice populations and may have aided the local adaptation of introduced Tm-J.     

Y chromosomes of self-identified Syeds from the Indian subcontinent show evidence of elevated Arab ancestry but not of a recent common patrilineal origin

Several cultural or religious groups claim descent from a common ancestor. The extent to which this claimed ancestry is real or socially constructed can be assessed by means of genetic studies. Syed is a common honorific title given to male Muslims belonging to certain families claiming descent from the Prophet Muhammad through his grandsons Hassan and Hussein, who lived 1,400 years ago and were the sons of the Prophet’s daughter Fatima. If all Syeds really are in direct descent from Hassan and Hussein, we would expect the Y chromosomes of Syeds to be less diverse than those of non-Syeds. Outside the Arab world, we would also expect to find that Syeds share Y chromosomes with Arab populations to a greater extent than they do with their non-Syed geographic neighbours. In this study, we found that the Y chromosomes of self-identified Syeds from India and Pakistan are no less diverse than those non-Syeds from the same regions, suggesting that there is no biological basis to the belief that self-identified Syeds in this part of the world share a recent common ancestry. In addition to Syeds, we also considered members of other hereditary Muslim lineages, which either claim descent from the tribe or family of Muhammad or from the residents of Medinah. Here, we found that these lineages showed greater affinity to geographically distant Arab populations, than to their neighbours from the Indian subcontinent, who do not belong to an Islamic honorific lineage.
