Geophysical Investigations at Teotepec,Mexico (1000 B.C.–A.D. 1000)

Abstract

Recent investigations at the site of Teotepec in the Sierra de los Tuxtlas in southern Veracruz, Mexico explored Middle Formative through Late Classic (1000 B.C.–A.D. 1000) socioeconomic conditions. A central focus was the form and function of the site's distinctive architectural configuration, the Long Plaza Group. During the 2007 and 2008 field seasons, a systematic geophysical survey of Teotepec obtained initial information on the layout, orientation, and possible function of the site's central architectural core. Results from the survey allow for a clear definition of the site's Long Plaza Group in addition to the identification of a possible ball court along its eastern edge. It is also clear that Teotepecans incorporated natural features into their architectural core by placing a pyramid atop a volcanic landform and modifying a natural basalt flow in order to create a level plaza. Finally, the geophysical data indicate significant time depth in architectural construction by suggesting diffirent mound construction techniques, thus underscoring the importance of Teotepec as a persistent place in a region marked by significant population fluctuations in the Formative and Classic periods.     

Flood-Damaged Canals and Human Response,A.D. 1000–1400, Phoenix,Arizona, USA

The scale of prehistoric canal construction in the North American Southwest peaked in a.d. 450–1450, during what has been named the Hohokam Millennium. Explanations for the eventual Hohokam “collapse” remain elusive. Environmental disturbances, such as floods, that were once manageable may have become unmanageable. Recent archaeological excavations of Hohokam canals in Phoenix identified stratigraphic evidence for three destructive floods that date to a.d. 1000–1400 within two large main canals in System 2, Hagenstad and Woodbury’s North. Woodbury’s North Canal was flood-damaged and abandoned sometime after a.d. 1300. Thereafter, no main canals of similar size were constructed to supply villages within System 2 and the area was depopulated. Our investigation provides the first stratigraphic evidence for a destructive flood during the late Classic period in the lower Salt River Valley and is compatible with the hypothesis of diminished resilience to environmental disturbance at the end of the Hohokam Millennium.     

Metal Working in the Northern Lowveld,South Africa A.D. 1000–1890

Abstract

The Iron Age archaeology of the northern Lowveld of South Africa is notable for the abundance of mining, metal working, and salt production sites recorded in the region. We report the results of scientific studies of the metallurgical remains recovered from 1965 to 1978 by Nikolaas J. van der Merwe, David Killick, and colleagues in various campaigns of survey and excavation in the Phalaborwa region, a major center of precolonial metallurgy. Both iron and copper ores occur in a carbonatite complex at Phalaborwa and were smelted in low-shaft furnaces of two different designs. Two radiocarbon dates of ca. 1000 b.p. are available for the mines themselves, which have now been completely destroyed. All other radiocarbon dates for the archaeological sequence at Phalaborwa fall in two groups, the first from the 10th to 13th centuries A.D., the second from the 17th through the 20th centuries A.D. Both iron and copper were smelted in both periods; tin-bronze and brass appeared towards the end of the earlier period.     

Multiscalar Settlement Ecology Study of Piedmont Village Tradition Communities,A.D. 1000–1600

This research analyzes the spatial patterning of settlement sites in relation to landscape features to determine the factors that influenced settlement location choices for Late Precontact (A.D. 1000–1600) Piedmont Village Tradition (PVT) communities in the Yadkin, Dan, Haw, and Eno river valleys of the Piedmont Southeast. We employ geographic information systems to estimate characteristics of past landscapes, nearest neighbor analysis to describe basic settlement patterns, and discriminant function analysis to determine spatial correlations between settlements and landscape features. We examine the data on three scales and also assess potential changes over time. Results indicate that settlement location choices were broadly similar on the regional scale, but specific influences varied between and within valleys and over time. When examined with current archaeological, ethnohistoric, and linguistic information, the results suggest that PVT communities engaged in regional interaction networks in highly variable ways and that the relationship between subsistence and settlement varied according to settlement size. Using these results, we explore the roles PVT communities played in the formation and maintenance of natural and cultural landscapes in the Late Precontact Southeast.     

Palaeohabitat of first settlement sites 1500–1000 B.C. in Guam,Mariana islands,western Pacific

Based on computer-aided models and geoarchaeological excavations, palaeohabitat renderings can account for ancient site locations and contexts much different from today in terms of sea level, coastal dynamics, slope erosion, nearshore ecosystems, native forests, and other factors. A case study illustrates this research in Guam of the Mariana Islands of the western Pacific, with specific reference to the 1500–1000 B.C. time interval. This time interval includes the oldest known archaeological sites in the Mariana Islands, directly relevant for understanding the context of ancient Austronesian population dispersals in the larger western Pacific region. The results also help toward larger understanding of coastal adaptations in dynamic settings.     

The Late Prehistoric,Protohistoric, and Early Historic periods in Eastern Arabia (ca. 5000–1200 B.C.)

This paper presents an overview of cultural developments in eastern Arabia during the Late Prehistoric, Protohistoric, and Early Historic periods (ca. 5000–1200 B.C.) as defined here. Emphasis is placed on the indigenous lithic industries, ceramics, architecture, burial practices, and subsistence data, while interregional ties and comparative chronology are treated as well. A unified chronological schema for the entire region is proposed which can function alongside local, regional sequences.     

Building Mounds. Longhouses,Coastal Mounds and Cultural Connections: Norway and the Northern Isles,c ad 800–1200

Abstract

WHY WERE important Viking longhouses built on large mounds of sand and then repeatedly rebuilt in precisely the same apparently challenging location? Generations of Viking–late Norse people did so, on sandy bays along the coasts of the Northern Isles of the United Kingdom. These prominent, ‘layered-up’ longhouse complexes were landscape statements. They reflected, in their location and the detail of their construction and use, the social attitudes and arrangements of those who lived in and visited them. The settlements played a pivotal role in power relationships and in the organisation of the local economy. This article explores the meaning of these focal settlement mounds through landscape archaeology; investigates building practices, stratigraphic detail and place-name associations; looks at their cultural roots in Scandinavia; and considers the role they played in the development of local social and political structures in Orkney.     

Wasserstoff als Energieträger. Herstellung,Lagerung, Transport

Abstract

This essay, written to accompany a lecture to new students on the course of Economic Analytics, at the Institute of Econometrics of the University of Lodz in Poland, provides a broad historical account of the development of econometrics. The context enables students to locate various aspects of econometric analysis. The origin of regression analysis is described and an account of cointegration analysis is presented. This essay is concerned primarily with the propagation of the ideas as distinct from the manner and the circumstances in which they have originated.     

Building Monks Mound,Cahokia, Illinois,a.d. 800–1400

Abstract

Cahokia (a.d. 800–1400), located near the confluence of the Mississippi and Missouri rivers, was the largest settlement in ancient North America. Monks Mound occupies the center of Cahokia and provides both a modern and ancient focal point for the site. Past investigations of Monks Mound explored issues of mound chronology and use. Recent soil coring around the perimeter clarifies the geological context and degree of preparation necessary before the mound was built. The results suggest that the mound is not optimally positioned for stability and its location may ultimately accelerate deterioration. Moreover, evaluation of the mound features and fill indicates that maximization of the geotechnical potential of sediments was not a primary concern for the Cahokians. Although poorly engineered relative to modern standards, the suitability of the mound as a platform may have been secondary to other design choices made while building the largest single mound in ancient North America.
