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.     

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.     

A FRESH LOOK AT A LITTLE-KNOWN SOUTHEASTERN COPPER PLATE

Abstract

Chauga (38OC47) is a mound site now under Lake Hartwell at the head of the Savannah River in Oconee County, South Carolina. Excavations in 1958–1959 by the University of Georgia recovered a Mississippian copper plate. Upon comparison to others of its kind, it is clear that this lesser-known plate encompasses some interesting design features, most notably the presence of the only known depiction of a chunkey stone on copper. We have recently created a more accurate representation of its design. The plate appears to portray many similarities to depictions of Birdman dancers: kilted dancers and dancing elders within the “Stack” style. Birdman themes are common in Mississippian iconography. Given the importance that copper plates have for interpreting Mississippian art and belief systems, this updated examination provides useful new information for researchers studying Mississippian iconography.     

COMPLEX MODE SUPERPOSITION ALGORITHM FOR SEISMIC RESPONSES OF NON-CLASSICALLY DAMPED LINEAR MDOF SYSTEM

This paper deals with a complex mode superposition method for the seismic responses of general multiple degrees of freedom (MDOF) discrete system with complex eigenvectors and eigenvalues. A delicate general solution, completely in real value form, for calculat-ing seismic time history response of the MDOF system which cannot be uncoupled by normal modes, is deduced based on the algorithms of the complex superposition method. This solution comprises of two parts which are in relation to the Duhamel integration to sine and cosine function respectively. The related term of the Duhamel integration to sine function is actually the displacement response of the oscillator with corresponding modal frequency and the damping ratio. The other can be transferred into a combina-tion of the displacement and velocity responses of the same oscillator. In order to meet the practical needs of seismic design based on code design spectra for various kinds of structures equipped by viscous dampers, the complex complete quadratic combination (CCQC) method is deduced following similar procedures such as the well-known CQC method, in which a new modal velocity correlation coefficient, together with a new modal displacement-velocity correlation coefficient are involved besides the modal displacement correlation coefficient in normal CQC formula. The new algorithm of CCQC is not only as concise as that of the normal CQC but also has explicit physical meaning. The results obtained from complex mode superposition approaches are discussed and verified in some examples through step by step integration computation under a prescribed earth-quake motion input. From these examplary analyses, it may be pointed that the CCQC algorithm normally yields conservative outcome and that the forced mode uncoupling approach has good approximation even the discussed examplary structures are strongly non-proportional.     

Nested Lumped-Parameter Model for Foundation with Strongly Frequency-dependent Impedance

A nested lumped-parameter model (LPM) consisting of frequency-independent springs and dashpots is proposed to represent the foundation-soil dynamic system with strongly frequency-dependent impedance in time domain. Due to the convergence and robustness of the complex Chebyshev polynomial, it is used to approximate the dynamic flexibility of the foundation by least-square curve-fitting technique. The comparisons with existing LPMs show that the present model can express the impedance by using a small number of elements and reduce oscillation of the solution appearing in simple polynomial approximations. Finally, several examples of foundations with irregular geometries are presented to show the application of nested LPMs.
