Health Consequences of European Contact in the Great Plains: A Comparison of Systemic Stress Levels in Pre‐ and Post‐Contact Arikara Populations

The biocultural effects of European contact varied considerably throughout the Americas. Some populations were decimated by colonialism, while others benefited from trade relationships and access to new technologies. It has been suggested that initial contact with European fur traders and explorers was economically favourable for Plains village populations, thereby facilitating a period of cultural florescence. In this study, we evaluate the hypothesis that Plains groups were better off than their predecessors during the initial contact period by comparing frequencies of enamel hypoplasia, cribra orbitalia, and porotic hyperostosis in pre‐ and post‐contact Arikara skeletal assemblages. We included both juveniles and adults in our sample to capture variation in the stress experience of different segments of the population. Our analysis revealed similarly low frequencies of cribra orbitalia in the pre‐ and post‐contact groups and no observed cases of porotic hyperostosis. Enamel hypoplasia, however, was significantly more prevalent among post‐contact Arikara villagers when compared to their pre‐contact counterparts, which suggests that stress levels were higher after European contact. Additionally, enamel hypoplasia was most common among post‐contact juveniles. The elevated frequency of enamel hypoplasia in the post‐contact sample combined with the low frequencies of cribra orbitalia and porotic hyperostosis suggests that disease stress, rather than nutritional deficiencies, was likely responsible for the decline in overall health following European contact. These results also suggest that juveniles are sensitive indicators of systemic stress within a population and should be included in bioarchaeological analyses of prehistoric health when available.

Vertebral Compression Fractures: Towards a Standard Scoring Methodology in Paleopathology

Vertebral compression fractures are the most common osteoporotic fractures in postmenopausal women. Notwithstanding, its clinical diagnosis remains ambiguous. In paleopathological studies, vertebral fractures and/or deformations are frequently disregarded. When observed, vertebral compression fractures are usually recorded without the support of quantifiable and comparable protocols. As such, Genant's semi‐quantitative method for vertebral compression fracture assessment was applied to a large sample (N = 196) from the Coimbra Identified Skeletal Collection, Portugal, and the reliability of the method was tested. Vertebral fracture scoring agreement was evaluated with the kappa statistic and the per cent of agreement. Intra‐observer agreement was almost perfect, whereas inter‐observer agreement was substantial to almost perfect. The Genant's semi‐quantitative scoring methodology is easy to apply and highly reproducible; as such, it should be adopted as the standard method to score vertebral fractures in any paleopathological investigation.

On the Trail of the Oldest Domestic Cat in Poland. An Insight from Morphometry,Ancient DNA and Radiocarbon Dating

It is believed on the basis of archaeozoological research that the domestic cat appeared in Central Europe during the Roman Period. In Poland, the domestic cat is a common species in medieval deposits. Only a few finds of cat remains of pre‐medieval age have been reported from Poland to date, including several specimens from deposits older than the Roman Period, dated to the pre‐Roman Period and even the Bronze Age. To clarify the earliest history of the domestic cat in Poland, the paper presents a review of the available published cat remains and adds some data about newly discovered remains. Combined methods of morphometry and ancient DNA were applied to enable distinction of wildcats and domestic cats. The domestic cat remains were radiocarbon dated. In six cases of domesticated cat reported in the literature, five were positively taxonomically verified, both by morphology and by genetic analysis, and one was recognised as a European wildcat. According to radiocarbon chronology, the oldest studied find is dated to the fourth–third century bc and represents a wildcat. Only two individuals of domestic cat – skeletons from Łojewo and Sławsko Wielkie, both from Kuyavia region (central‐northern Poland) – represent the Roman Period (first–third century ad ), and they are the oldest confirmed domestic cats in Poland.

Eneolithic Cattle Burials from Aljmaš‐Podunavlje and Osijek‐Retfala,Croatia

Two single bovine burials and one mixed animal burial (containing bovine and canid skeletal remains) have been unearthed at two Baden culture sites, Aljmaš‐Podunavlje and Osijek‐Retfala located in Eastern Croatia. Zooarchaeological analysis attributed the faunal remains to domesticated cattle (Bos taurus) and in one case a dog (Canis familiaris). Almost complete and articulated skeletons of subadult or adult cows were found in all three examined features, while pit 59/60 from Aljmaš also contained a skull belonging to an adult‐domesticated cattle and a skeleton of a very young dog, 2–3 months old. All of the skeletons are well preserved and display no evidence of carcass processing indicating that the animals were buried intentionally. Consideration of the positions in which these animals were interred and their relationship with nearby deposits enables discussion of potential animal burial strategies and possible connections with certain ritual practices in which cows and in one case a dog played important roles. The described burials represent the southernmost known distribution of the rite discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Elemental Characterization by EDXRF of Imperial Longquan Celadon Porcelain Excavated from Fengdongyan Kiln,Dayao County

A mass of Longquan porcelain shards carved with ‘Guan’ or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy‐dispersive X‐ray fluorescence (EDXRF). The results indicate that the contents of TiO₂ and Fe₂O₃ in the body vary in the Hongwu and Yongle eras. Compared with Longquan glazes in the Southern Song Dynasty, the average values of K₂O, Fe₂O₃ and TiO₂ are higher, but that of CaO is lower in early Ming imperial porcelain glazes. Principal components analysis (PCA) shows that different degrees of elutriation of the same raw materials are the main reason for this difference in the Hongwu and Yongle periods. However, the raw materials of imperial porcelain glazes show no obvious changes and have inherited the earlier tradition. The production and firing technology of imperial porcelain reached a higher level and had not declined in the Early Ming Dynasty.     

The Origin and Archaeometallurgy of a Mixed Sulphide Ore for Copper Production on the Island of Kea,Aegean Sea,Greece

At the hill of Agios Symeon, on the island of Kea, Aegean Sea, Greece, ancient metallurgical slags with a high Pb–Zn–Cu content have been found. Thermodynamic simulations have been carried out, using the FactSage? thermodynamic database computing system, with a view to understanding the ancient metallurgical processes that produced the observed slag compositions and morphologies. The simulations demonstrate that the slag samples resulted from Cu‐making processes. It would thus appear that mixed ores were used, containing Cu₂S–FeS–PbS with significant amounts of sphalerite (ZnS) as impurity. The roasted ores were reduced at relatively high oxygen potentials at ～1125°C to form Cu containing low levels of Pb, Fe and Zn.     

Predicting Regional Self‐Identification from Spatial Network Models

Social scientists characterize social life as a hierarchy of environments, from the microlevel of an individual's knowledge and perceptions to the macrolevel of large‐scale social networks. In accordance with this typology, individuals are typically thought to reside in micro‐ and macrolevel structures, composed of multifaceted relations (e.g., acquaintanceship, friendship, and kinship). This article analyzes the effects of social structure on micro outcomes through the case of regional identification. Self‐identification occurs in many different domains, one of which is regional; that is, the identification of oneself with a locationally associated group (e.g., a “New Yorker” or “Parisian”). Here, regional self‐identification is posited to result from an influence process based on the location of an individual's alters (e.g., friends, kin, or coworkers), such that one tends to identify with regions in which many of his or her alters reside. The structure of this article is laid out as follows: initially, we begin with a discussion of the relevant social science literature for both social networks and identification. This discussion is followed with one about competing mechanisms for regional identification that are motivated first from the social network literature, and second by the social psychological and cognitive literature of decision making and heuristics. Next, the article covers the data and methods employed to test the proposed mechanisms. Finally, the article concludes with a discussion of its findings and further implications for the larger social science literature.
