Sacred landscapes of the southern Brazilian highlands: Understanding southern proto-Jê mound and enclosure complexes

Fieldwork involving survey, detailed topographic mapping, and excavations in Pinhal da Serra, Rio Grande do Sul, Brazil, has revealed a highly-structured landscape revolving around funerary/ceremonial structures that began around A.D. 1000. This paper focuses on the results of detailed topographic survey of mound and enclosure complexes and their interpretation in light of southern Jê ethnohistorical and ethnographic data. We compare the architectural patterns of mortuary architecture from this study with fundamental spatial features of historic Kaingang’s social organisation, mortuary rituals and cosmogony myth. Our results suggest historical continuity in the organisation of space in cardinal directions (E–W), topography (low and high places), and in circular/concentric spatiality revealed in the southern proto-Jê mound and enclosure complexes. It is argued that small paired mound and enclosure complexes are associated with the material representation of a dual ranked opposition materialised in proto-Jê moiety cemeteries where important persona were buried.     

Investigating experimental knapping damage on an antler hammer: a pilot-study using high-resolution imaging and analytical techniques

Organic (bone, antler, wood) knapping tools were undoubtedly a component of early human tool kits since the Lower Palaeolithic. Previous studies have identified pitting and the occasional presence of embedded flint flakes as important features for recognizing archaeological bone and antler percussors. However, no systematic protocol of analysis has been suggested for the study of this rare archaeological material. Here we present qualitative and quantitative results of a preliminary analysis of an experimental knapping hammer, using a novel combination of microscopy (focus variation optical microscope and scanning electron microscope), micro-CT scanning and energy dispersive X-ray spectroscopy. These imaging and analytical techniques are used to characterize use-damage from the manufacture of handaxes. This paper highlights the strengths and weakness of each technique. Use-wear on the working area included attritional bone loss, micro-striations and compaction of the outer layer of the antler matrix from repeated hitting of the beam against the sharp edge of the handaxe during knapping. Embedded flint flakes were also identified in the pits and grooves. This combination of high-resolution imaging techniques is applicable to fragile archaeological specimens, including those encrusted by sediment or encased in matrix.     

The Groin Vaults of St. John Hospital in Jerusalem: An Experimental Analysis on a Scale Model

The St. John Hospital is part of a larger complex of buildings known as the Hospitallers Quarter, located south of the Holy Sepulchre in Jerusalem. At present, the hospital looks like an irregular volume both in height and in plan; it is covered by ten groin vaults resting on very stocky pillars. Each vault is formed by intersecting double curvature surfaces. In order to verify the effectiveness of continuous carbon fiber reinforced polymer sheets reinforcement, bonded at the extrados of vaults, laboratory tests were carried out on a 1:5 scale model, built with materials and construction techniques similar to those of the real building. Experimental tests were performed on the unstrengthened and strengthened vault. The experimental results shown that the strengthening system is able to increase the collapse load of the vault, without substantial variation of the initial stiffness.     

Out of the crisis: an empirical investigation of place-specific determinants of economic resilience

This article attempts to isolate the structural characteristics that affect the resilience of a regional economy. It focuses on the role played by related/unrelated variety and differentiated knowledge bases as drivers for regional resilience and originally explores their interdependences. Italy is the empirical setting, and Italian local labour systems the unit of analysis. Regional resilience is measured as growth of the employment rate after the Great Recession that began in 2008. Results confirm the importance of related variety and of differentiated knowledge bases as drivers for regional resilience. We found support of the creative capacity of culture argument, providing evidence that a moderate concentration in symbolic knowledge-based economic activities contributes to resilience. Synthetic and analytical knowledge-based activities provide positive and no support to regional resilience, respectively. Finally, the relatedness of the symbolic knowledge-based activities increases regional economic resilience. Some policy implications are then derived from these findings.     

A new method for the quantitative analysis of cutmark micromorphology

Cutmarks found on the fossilised bones of butchered animals provide direct evidence for the procurement of meat through technological means. As such, they hold some of the oldest available information on cognitive ability and behaviour in human evolution. Here we present a new method that allows a three-dimensional reconstruction of cutmark morphology and the quantification of profile parameters. We have tested this new technique on cutmarks that were experimentally inflicted on a pig rib using a steel knife and an un-retouched flint flake at different angles. The method allows for the cross-sectional shape, the sharpness and depths of the resulting cutmarks to be quantified. The data show that knife mark sections are characterised by a V-shape or √-shape depending on the inclination of the knife. Cutmarks produced with the flint flake were less clearly defined and generally less sharp than those produced by the knife. We discuss the method's potential to provide new information on butchery technique and cognitive abilities developed by the human lineage, from the earliest tool-using hominins through to modern Homo sapiens.     

Worked and decorated shell discs from southern Arabia and the wider Near East

This article presents and discusses a corpus of worked and decorated shell discs from recently excavated archaeological sites in southern Arabia, including Dibba (northern Oman), Saruq al‐Hadid (UAE) and Sumhuram/Khor Rori (southern Oman). The artefacts are compared to a wide range of shell discs from controlled excavations in Arabia and the broader Near East in order to better understand their date, manufacture and use. The comparative study highlights the wide distribution of decorated shell discs across the ancient Near East, particularly during the early Iron Age, and the complex economic and cultural connections that underpinned the collection, crafting, exchange and significance of such items.     

Micro-narratives in Contemporary Chinese Art: A Case Study of Cao Fei's Pearl River Delta Anti-heroes

This paper investigates the representation of micro-narratives in contemporary Chinese art by examining the multi-layered narratives in Cao Fei's Pearl River Delta Anti-heroes performed at the opening of the 2^nd Guangzhou Triennial in 2005. I consider Cao's work as a hyper-realistic portrayal of the micro-narratives of the Pearl River Delta region in a mediated form highly influenced by the media, entertainment industry and popular culture of the region and Hong Kong. Theatricality, kitsch and the distinctive local essence of South China are revealed in the form of a TV soap opera and the use of colloquial Cantonese throughout the performance, along with occasional Putonghua or Mandarin. Language as a signifier of cultural politics has been deployed as an indispensable tool to empower the region within the broader body politic of the People's Republic of China.     

Zooarchaeological Evidence for Domestic Rituals in the Iron Age Communities of North‐Eastern Iberia (Present‐Day Catalonia) (Sixth–Second Century BC)

Many socio‐economic changes occurred in southern Europe during the first millennium BC. In north‐eastern Iberia societies evolved from the small‐scale local groups of the Late Bronze Age to the more complex societies of the Iron Age. Together with a diversity of material changes (detected in pottery, agricultural techniques, architecture, etc.), a new ritual manifestation is attested in the Ancient Iberian Period (about 550 BC), lasting until some time after the Roman conquest. This consisted of sheep and goats (among other species) being carefully deposited below the floors of some domestic buildings. In this article the characteristics of these associated bone groups are described and their significance is discussed.
