Diet,nutritional status and oral health in hunter‐gatherers from the central‐northern coast of Patagonia and the Chubut river lower valley,Argentina

Archaeological research in central‐northern Patagonia (Atlantic coast and lower the valley of Chubut river) showed that this area was used since at least the Middle Holocene. Stable isotope analyses (¹³C and ¹⁵N) of human bone samples indicate that hunter‐gatherers living in that area had a terrestrial‐marine diet including guanaco meat, land plants, mollusks and pinnipeds. Despite this general trend, intersite variability and changes through time were noted, especially after the late Holocene. These results have been reinforced by archaeofaunal, technological and bioarchaeological records. In this paper, three hypotheses are examined: (a) the diet of these populations was complete and rich enough to ensure good health status and avoid nutritional deficiencies; (b) carbohydrate consumption increased progressively after 1000 BP, when pottery technology was adopted and (c) this kind of mixed diet would have been qualitatively more nutritious than that of other populations of the region, which would have resulted in better nutritional and healthy conditions. These three hypotheses are compared with dental results obtained from 563 permanent teeth from 45 individuals (34 adults and 11 juveniles from both sexes), rescued from burial sites. Indicators of oral health were assessed through the observation of caries, abscesses, wear, pulpar cavity exposure and ante mortem loss. Features of nutritional status such as enamel hypoplasia, porotic hyperostosis and cribra orbitalia were also examined. Given the availability of direct radiocarbon dating for most of the sample, three temporal series were determined: ‘Before 1000 BP’, ‘1000–5000 BP’ and ‘Post‐contact’. No evidence of alimentary stress or iron deficiency was found in individuals from the three series, which accounts for healthy and good nutritional life conditions. After 1000 BP, the results show a progressive increase in the caries percentage and a decrease in abscesses, dental wear and ante mortem losses frequency. This is possibly related to more consumption of processed foods in the last 1000 years. These results were compared with similar studies based on samples from different environments and latitudes of Patagonia. Evidence suggests that mixed diets (marine‐terrestrial) would have been more appropriate and nutritionally complete than exclusively marine or terrestrial diets.

A case of multiple metastasis in Late Holocene hunter‐gatherers from the Argentine Pampean region

Chenque I site is a prehistoric cemetery located in Lihué Calel National Park (La Pampa province) in the Western Pampean region of Argentina. Hunter‐gatherer societies made use of this site during the Final Late Holocene for at least 700 years (1030–370 BP). Currently 41 burial structures have been excavated, and more than 150 individuals have been recovered. There is great variability in mortuary patterns at the site (simple, multiple, primary, secondary burials, and also a variant not previously observed in the region). The life‐ways of this population have been investigated through the evaluation of several biological and cultural factors. Several pathological conditions have also been identified in this cemetery. Burial no. 12 contains a skeleton of an adult male that shows multiple pathological lesions, compatible with a neoplastic disease. These lesions have been analysed using several methodological strategies: macroscopic, radiological and microscopic. This is the first time that this kind of disease has been identified from a prehistoric burial in Argentina. In this paper the location and characteristics of the lesions are evaluated, and the different neoplastic diseases that could have produced them are discussed. Since the people buried in this cemetery belonged to highly mobile societies, a key issue is to infer the consequences that this disease would have had on the dynamics of the group in which this person lived, because of the gradual deterioration of his health and physical strength.

Pre-Clovis in Texas? A critical assessment of the “Buttermilk Creek Complex”

Lithic artifacts from the lowest strata of the Debra L. Friedkin site, located on Buttermilk Creek in central Texas, have been interpreted as an undisturbed pre-Clovis assemblage (Waters et al., 2011a). Stone tools and debitage were recovered from sediments stratified just below diagnostic Clovis artifacts and dated by OSL to between 13.2 and >15.5 cal kya. Invoking commonly observed cultural and natural site formation processes, we offer an alternative explanation of the “Buttermilk Creek Complex” as a Clovis assemblage in secondary association with the dated sediments.     

A Mississippian Mace at Iroquoia's Southern Door

Abstract

This paper documents a Mississippian chipped stone mace, found by Lyle Edger, an amateur collector, in an agricultural field in Nichols, NY, along the Susquehanna River. This crown-form mace is made out of Dover chert and was probably produced by Mississippian people who lived in Middle Tennessee, circa A.D. 1200–1400. We argue that the Nichols Mace could have been acquired by Iroquoian people as the result of either a gift or diplomatic negotiations. We conclude that the meanings the mace held for Iroquoian people were likely tied to how they acquired it.     

Multi‐analytical Studies of Archaeological Chinese Earthen Plasters: The Inner Wall of the Longhu Hall (Yuzhen Palace,Ancient Building Complex,Wudang Mountains,China)

The Yuzhen Palace is one of the nine palaces in the Ancient Building Complex built by order of the Yongle Emperor during the Ming dynasty. The buildings were built with dressed black bricks. As a result of the planned national South–North Water Diversion project, the water level in the Danjiangkou Reservoir that surrounds the Yuzhen Palace was expected to rise by approximately 15 m. To avoid submersion of the site, three gates were elevated by 15 m in 2013 and other buildings dismantled, for later reconstruction. The characterization of the construction materials has therefore become of primary importance. Here, we present results on the plasters of the Longhu Hall. The analysis of materials involved a multi‐analytical approach combining optical and electron microscopy with X‐ray and vibrational spectromicroscopies and thermogravimetry. The results indicated the use of two earthen plaster layers and a whitewash finish coating applied over a thin preparatory intermediate layer to improve the adherence of the finish coating to the earthen plaster. Ramie and straw fibres identified in the earthen plasters were added to reduce shrinkage and cracking during drying. The raw materials used and the application technique pointed to a well‐established construction industry using traditional earthen building materials together with lime technology.     

Experimental territoriality: Assembling the Kaesong Industrial Complex in North Korea

This paper examines the interactions of sovereignty and political economy that shape North Korea's Kaesong Industrial Complex (KIC)—an economic zone jointly operated by North and South Korea. Drawing on contemporary literatures concerning sovereignty, territoriality, and sites of political economic experimentation in East Asia, we argue that the KIC represents an experimental form of territoriality: one that is particularly volatile due to its unique geopolitical location where interaction among the various actors that compose it periodically shuts down or threatens to suspend the project. This volatility cannot be reduced to the structure of the North Korean regime alone, however. Rather, it must be situated within the continuation of a framework of enmity on the Korean peninsula as well as the ethical and political conundrums raised by the largely capitalist nature of the KIC as a form of inter-Korean economic cooperation.     

Diet and Oral Health of Populations that Inhabited Central Argentina (Córdoba Province) during Late Holocene

The aim of this work is to study, from a bioarchaeological perspective, the diet and oral health of the populations that inhabited Central Argentina in two periods which would reflect changes in subsistence strategies: earlier late Holocene (ca. 2500–1500 years BP) and later late Holocene (ca.1500–400 years BP). The sample is composed by 83 adult individuals from 47 archaeological sites. We considered five non‐specific indicators of stress, infectious and degenerative diseases: hypoplasia of dental enamel, dental caries, abscesses, antemortem teeth loss, and calculus. We also considered hypercementosis, dens in dens, and agenesis. We test intraobserver error by means of intraclass correlation coefficient and analysis of variance of repeated measures. We calculated prevalence by sex, age, geographic subregion, and chronological period. We applied Chi‐square (X²) to test statistical significance of observed differences. Considering the sample as a whole, low prevalence of dental caries (10.27%), abscesses (16.52%), and hypoplasia (10.84%) are coincident with values observed for populations with mixed or hunter‐gathering subsistence strategy. In later late Holocene, high incidence of caries should be considered as indicator of consumption of C4 vegetables or other carbohydrate‐rich vegetables, such as legumes of Prosopis sp. Also, moderate values of dental enamel hypoplasia should be related with metabolic‐systemic stress episodes. Summarizing, these results are coincident with isotopic, archaeological, and ethnohistorical evidences which suggest climatic, social, and demographic pressures that might have affected the lifestyle of these populations before the Spanish conquest.

Advances in Polynesian Prehistory: A Review and Assessment of the Past Decade (1993–2004)

The pace of archaeological research in Polynesia has intensified in recent years, resulting in more than 500 new literature citations over the past decade. Fieldwork has continued in such previously well-studied archipelagoes as Tonga and Samoa in Western Polynesia, and Hawai’i and New Zealand in Eastern Polynesia, and has expanded into previously neglected islands including Niue, the Equatorial Islands, the Austral Islands, and Mangareva. The emergence of Ancestral Polynesian culture out of its Eastern Lapita predecessor is increasingly well understood, and the chronology of Polynesian dispersal and expansion into Eastern Polynesia has engaged several researchers. Aside from these fundamental issues of origins and chronology, major research themes over the past decade include (1) defining the nature, extent, and timing of long-distance interaction spheres, particularly in Eastern Polynesia; (2) the impacts of human colonization and settlement on island ecosystems; (3) variation in Polynesian economic systems and their transformations over time; and (4) sociopolitical change, especially as viewed through the lens of household or microscale archaeology. Also noteworthy is the rapidly evolving nature of interactions between archaeologists and native communities, a critical aspect of archaeological practice in the region.

The emergence of status inequality in intermediate scale societies: A demographic and socio-economic history of the Keatley Creek site,British Columbia

Explaining the emergence of status inequality in human societies is an important priority for many anthropological archaeologists, particularly those whose research includes intermediate scale societies (complex hunter–gatherers and early agriculturalists). Yet, fine grained records of emergent inequality are still exceedingly rare. This paper outlines a fine-grained record of cultural change from the Keatley Creek site, a complex hunter–gatherer village in British Columbia, in which it is possible to recognize the emergence of inequality and its demographic and economic correlates. Results of the study suggest that status inequality emerged abruptly after an extended period of socio-economic stability in the village under conditions of adversely altered resource conditions, demographic packing, and subsistence resource diversification and extensification.     

Compound Verb Processing in Second Language Speakers of Persian

This study investigates compound verb processing in second language speakers (L2) of Persian. Forty-six near-native L2 speakers of Persian were tested to examine the processing of transparent (non-idiomatic) and opaque (idiomatic) compound verbs, under masked priming paradigm. The results revealed a significant nominal priming effect in the opaque condition, and a numerically stronger nominal priming effect in the transparent condition. There was also an increase in the processing load on the parser when the target was an opaque compound. The results of this study seem to be compatible with the dual access or dual route hypothesis, yet with the version that assumes the two routes are activated in parallel rather than the version that assumes high frequency words are represented lexically but low frequency words are decomposed.
