Poverty Point Objects Reconsidered

In this paper we examine the enigmatic but plentiful hand-molded, baked-clay objects known as Poverty Point Objects (PPOs) from a number of different facets. Although the vast majority of these Terminal Archaic artifacts are found in the Lower Mississippi Valley, they also are found at sites as far north as Clarksville, Indiana, and as far east as the Atlantic Coast of Florida. Although most archaeologists generally assume PPOs were used primarily for roasting food, we consider a variety of other possible functions, including their use in boiling water and as symbolic tokens linking the far-flung Poverty Point culture area. We demonstrate that even though a few other archaeological cultures in the world used round clay balls for cooking, the Poverty Point culture was unique in the care, variety, and standardized forms of its baked-clay objects. We discuss the various PPO types and their possible functions in nine distinct regions in the southeastern United States and, based on our thin-section analyses of 66 samples, we demonstrate that PPOs circulated among different sites in these regions.     

Performing Hospitality in Moldova: Ambiguous,Alternative, and Undeveloped Models of National Identity

This paper examines performances of hospitality in everyday life to explore the lived experience of “being Moldovan”. National identity in Moldova can only be understood by reference to the peculiarities of history—to the presence of a neighbouring kin-state (Romania), a multiethnic population, Soviet ideology, and successive efforts at nation-building. The instabilities, contradictions, and ambiguities of national identity are also experienced and interpreted, as they are regularly performed in informal and formal settings. The “hospitality” of Moldovans—performed daily through linguistic code-switching, in practices of buying and selling, in life-cycle celebrations such as weddings, and in the official greeting and welcoming of dignitaries and visiting delegations by folk-costumed performers—is, paradoxically, an important site of this experience of ambiguity. The same set of practices both renders its performers “masters of their own houses”, while at the same time revealing the limits of the metaphor.     

The Mechanism and Kinetics of In Situ Conservation of Iron Cannon on Shipwreck Sites

Analysis of the pre‐disturbance values of the in situ corrosion parameters on historic iron shipwrecks and artefacts has established that the arithmetic product of the pH and corrosion potential is dependent on the burial environment and provides a unique insight into the objects' state of decay. The value of the product changes during in situ conservation treatment with sacrificial anodes, and reaches a minimum at which point the treatment is completed. Treatment times vary with water‐depth, being faster on shallower sites and shorter for more extensively corroded artefacts. The model was developed using data from the Duart Point wreck (1653), the Monitor‐styled warship HMVS Cerberus (1926) and a series of wrecks in Australia and the USA.     

Seismic Behaviors of RC Frame Beam-Column Joints under Acid Rain Circle: A Pilot Experimental Study

This research was carried out to investigate the seismic performance of RC beam-column joints under acid rain circle via comparison of energy dissipation behavior and failure mechanism of joints with different corrosion levels and axial compression ratio. At the initial corrosion level, the strength, ductility, and energy consumption of RC beam-column joints improved slightly; at a later stage, the bearing and deformation capacity decreased as the corrosion rate of steel rebars increased. The test shows that with the increasing of the axial compression ratio, the initial stiffness and ultimate bearing capacity of the joints will increasing if the corrosion levels are the same, but the ductility of that will decrease.     

Taking Direction: New Dramaturgies of Science from the Splice Symposium and the Performing Science Conference

Abstract

This short article responds to two recent conferences on performance and science: the Splice Symposium (Chimera Network/University of Notre Dame) and Performing Science (University of Lincoln). Rather than a conventional conference report, the author reflects on a selection of presentations in the light of issue one of ISR’s ‘theatre and science’ series.     

Simplified Seismic Sidesway Collapse Capacity-Based Evaluation and Design of Frame Buildings with Linear Viscous Dampers

This article describes a simplified procedure for estimating the seismic sidesway collapse capacity of frame building structures incorporating linear viscous dampers. The proposed procedure is based on a robust database of seismic peak displacement responses of viscously damped nonlinear single-degree-of-freedom systems for various seismic intensities and uses nonlinear static (pushover) analysis without the need for nonlinear time history dynamic analysis. The proposed procedure is assessed by comparing its collapse capacity predictions on 272 different building models with those obtained from incremental dynamic analyses. A straightforward collapse capacity-based design procedure is also introduced for structures without extreme soft story irregularities.     

Addressing seasonal site use through ancient DNA species identification of Pacific salmon at Dionisio Point,Galiano Island,British Columbia

We use ancient DNA analysis to identify Pacific salmon vertebrae to species in order to provide an important line of evidence that helps to establish the timing of seasonal residence at a Pacific Northwest Coast village site. Ancient DNA results from House 2 at Dionisio Point allow a characterization of the salmon fishery. Ten of eleven randomly selected smaller-sized salmon vertebrae were positively identified as sockeye salmon (Oncorhynchus nerka) while only a single pink salmon (Oncorhynchus gorbuscha) was identified. Of the 322 whole salmon vertebrae identified from House 2 occupation deposits during zooarchaeological analysis, 58 percent measure less than 8.0 mm and 70 percent are less than 8.5 mm in maximum transverse diameter. Together with documented aspects of the material record from Dionisio Point, most notably the vertebrate fauna from House 2, the indication that sockeye was the primary focus of the Dionisio Point salmon fishery suggests the site was inhabited during the spring and summer. This approach to the identification of season-specific site occupation has the potential for application over much of the Northeast Pacific.     

Have you heard the one about the disappearing ice? Recasting Arctic geopolitics

This article unpacks the discourse of Arctic geopolitics evident in the space-making practices of a wide variety of actors and institutions, offering an exploration of the ways in which the Arctic is emerging as a space of and for geopolitics. Tracing the well-aired story of Arctic geopolitics through neo-realist readings of climate change, the melting of polar ice, increasing competition for resources and so on, two kinds of spatial ordering are identified as being entwined in orthodox Arctic geopolitics. The first has to do with Arctic space as such, and its open, indeterminate nature in particular. The perceived openness of Arctic space enables it to become a space of masculinist fantasy and adventure, which is mirrored in contemporary accounts of Arctic geopolitics. It is suggested that this is entwined with and nourishes the second ordering of Arctic space in terms of state-building and international relations. The working out of these spatial orderings in recent interventions in Arctic geopolitics is explored via three examples (two Arctic exhibitions in London, the Russian Polar expedition of 2007 and ’sovereignty patrols’ by Canadian Rangers). In conclusion, the article presents avenues for further critical research on Arctic geopolitics that emphasizes embodiment, the resolutely (trans)local, and a commitment to the everyday.     

Seismic Behavior of L-Shaped RC Squat Walls under Various Lateral Loading Directions

Considerable progress has been made on the research of non-rectangular reinforced concrete (RC) squat walls over the past decades. However, the experimental data of L-shaped RC squat walls remain limited, especially for their seismic behaviors under non-principal bending actions. This paper presents an experimental and numerical investigation on L-shaped RC squat structural walls with an emphasis on how varying the directions of lateral cyclic loading influences the seismic responses of these walls. Four L-shaped specimens are tested under lateral cyclic displacements and low levels of axial compression The variables are axial loads and lateral loading directions. The performance of specimens is discussed in terms of cracking patterns, failure mechanisms, hysteretic responses, deformation components and strain profiles. Furthermore, three-dimensional finite element models are developed to supplement the experimental results. The direction of lateral loading is found to have a significant effect on the peak shear strength of L-shaped RC squat walls.     

Social memory and ethnic identity: Ancient Greek drama performances as commemorative ceremonies

This paper is an ethnographic account of ancient Greek drama performances that take place in contemporary Greece. The material presented here is part of the data that were collected, mainly through participant observation, interviews and newspapers, during 1997 and 1998 in Athens. The paper illuminates an aspect of modern ancient drama performances that has not been taken into account until today: it treats them as commemorative ceremonies that produce, reproduce, and transmit social memory. The interrelation and interdependence between social memory and ethnic identity construction processes are analyzed and is shown that ancient drama performances, due to specific characteristics, constitute something more than mere theatrical events (as they are defined within the Western tradition). These performances, which convey, sustain, and transmit perceptions of a glorious culture of the past, become, for their creators and spectators, as members of an ethnic group, occasions for consciously remembering their ethnic past, and coming, in a way, to a "mythical identification" with it.
