A Multidisciplinary Approach for the Archaeometric Study of Pozzolanic Aggregate in Roman Mortars: The Case of Villa dei Quintili (Rome,Italy)

This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili.

The application of biometry and LA-ICP-MS to provenance isolated bones: a study of hominin remains from Oumm Qatafa Cave,Judean Desert

Three hominin phalanges were recently identified in old faunal collections attributed to the Late Acheulean (Layer D2) dated to ca. 213 Kya, from Oumm Qatafa Cave (Judean Desert), a site excavated in 1928–1949. In terms of general appearance (colour, patina and adhering sediment), these specimens resembled the fauna with which they were found, but the likelihood of stratigraphic problems especially in old excavations, the presence of 4th millennium b.c. burials in the topmost Layer A at the site and the absence of any mention of Late Acheulean hominin remains in publications relating to the site prompted us to verify that the phalanges were indeed in situ. Osteometric examination showed the phalanges to be indistinguishable from those of Middle Paleolithic Levantine anatomically modern humans (AMHS) as well as Upper Paleolithic and recent populations, thus contributing little to the resolution of their provenance. To further investigate this issue, we compared the elemental composition of the phalanges to that of fauna from the same and overlying archaeological layers using non-destructive laser ablation–inductively coupled plasma mass spectrometry (LA-ICP-MS). The results showed a close resemblance in elemental composition between the phalanges and fauna from Layer D2, implying that they are in situ. This would indicate either an early occurrence of AMHS in the region or the presence of an ancestral archaic Homo. We propose that LA-ICP-MS offers a useful minimally invasive method for provenancing isolated human and faunal remains.     

The effect of culture on home-ownership

In this paper, we analyze the role of culture in determining whether, or not, an individual is a homeowner. We use data on first-generation immigrants who arrived in the United States under 6 years old. Following the epidemiological approach, any dissimilarity in the proportion of homeowners by country of origin may be interpreted as a consequence of cultural differences. Our estimates indicate that there is a positive and statistically significant relationship between the cultural proxy and the immigrants’ choice of home-ownership. Additionally, we present evidence of different mechanisms of transmission of culture, which reinforces our results on the cultural effect.     

Anthropogenic units fingerprinted by REE in archaeological stratigraphy: Mas d'Is (Spain) case

On occasions, archaeologists have to deal with serious difficulties to differentiate between processes that ultimately are responsible for the formation of stratigraphic units.Sometimes we face problems related with depositional units in multilayered deposits and other times, we ask for the character of some dark surface soils, very similar to natural paleosols and usually associated with archaeological findings. In both cases, the problems we must address concern the relative impact of human activities.The imbalance between anthropic and natural processes in the formation of archaeological deposits is crucial for a correct interpretation of the processes involved in the formation of archaeological sites, but also of their occupation-abandonment dynamics and the understanding of their spatial behaviors and relationship with the environment.In this paper we propose a new methodological approach for the identification of anthropogenic fingerprints in stratigraphic units through Rare Earth Elements (REE) soil analysis. The role of REE for the effective identification of sediment provenance due to their coherent behavior during weathering, erosion and fluvial transportation and their high resistance to chemical mobilization is well known in other areas of knowledge. We try to explore its potentiality in a challenging archaeological context. Our purpose was to identify human traces in stratigraphic units where archaeological materials are scarce or absent intertwined with others richer in archaeological remains by the determination of multiple elements and statistical studies. We believe that Rare Earth Elements (REE) soil analysis provides unique insights for a better characterization of natural and archaeological sediments but more importantly to recognize different stages of the gradient. We expect to discern between natural versus anthropic units and between primary versus secondary deposits (redeposition), using the case of the Neolithic site of Mas d'Is (Alicante, Spain) as an example. The application of the Principal Component Analysis (PCA) remarks differences in REE values, those analysis show differences between units of undoubtedly anthropogenic origin and control samples taken from natural sediments –including marls bedrock–, in their vicinity, but also we could notice finer nuances like the degree of human contributions to paleosols formation.     

First molecular identification of a hafting adhesive in the Late Howiesons Poort at Diepkloof Rock Shelter (Western Cape,South Africa)

The hafting of tools using adhesive is one of the innovative features that characterizes the southern African Middle Stone Age. This technology has mainstream implications but remains insufficiently documented, largely due to unequal organic preservation and non-adapted analytical procedures. A notable exception is provided by the recent results from the site of Sibudu (Lombard, 2006; Wadley et al., 2009).     

Attitudes toward War in the United States and Iran

Understanding the determinants of attitudes toward war is important for the prevention of military conflicts and the promotion of peaceful conflict resolution. To examine American and Iranian attitudes toward war, questionnaires were administered to American and Iranian college students in the United States and Iran respectively. The results of the study revealed that American students generally have more positive attitudes toward war than Iranian students. Since most Iranians in the sample experienced eight years of war with Iraq whereas Americans never had direct experience of war, it was predicted that direct experiences of military action could explain this cross-national difference. Among Iranians those who experienced the Iran–Iraq war had more negative attitudes toward war compared to Iranians who did not have such experiences. The results further demonstrated that being authoritarian, religious and male were independently related to having positive attitudes toward war in both samples.     

The Ter Sámi according to the Russian census of 1858: Ethno‐social characteristics

Census material representing the tax‐paying segments of the population of the Russian Empire can be used as an empirical basis for carrying out local research in the field of ethno‐social history. This article deals with ethno‐social characteristics of the Ter Sami of the Kola Peninsula, and is based on archival data from a local census report from 1858. Special attention is given to family structure, marriage preferences and the distribution of family names.
