Coles Creek fauna procurement strategies: subsistence diversity among late prehistoric hunter-gatherer-horticulturalists in the Lower Mississippi Valley

In the late 1980s, a collaborative effort between Harvard University’s Lower Mississippi Survey and Tulane University’s Center for Archaeology launched a study examining the causes and consequences of subsistence change in the Lower Mississippi Valley. The Osceola Project contributed the first formal study of late prehistoric faunal remains within the Alluvial Plain, becoming the standard against which all subsequent Coles Creek faunal assemblages have been measured. Recent evidence recovered from three sites located in the Eastern Uplands presented the opportunity to compare and contrast vertebrate subsistence in these two distinct physiographic regions. We hypothesize that a clear distinction exists between lowland and upland Coles Creek procurement strategies. This article evaluates this claim by examining species diversity, spatial patterns, and temporal trends evident within an eight-site sample. The results suggest that the primary factor influencing Coles Creek fauna procurement was the immediate environment, and that the composition of Late Woodland period diets may be a reflection of efficiency of effort rather than food access or scarcity.     

Geoarchaeology and spatial distributions of the ‘Coche Quemado' obsidian source in north-western Patagonia

In north-western Patagonia, obsidian was used during the entire Holocene, and its importance increased with time. Recent fieldwork discovered a new obsidian source located in the Río Grande, which was called ‘Coche Quemado' (CQ). The results indicate that the CQ source has a different geochemical signal than all other sources in the region. Its use is spatially restricted to piedmont and, to a lesser extent, the plains. Chronologically, CQ was exploited in the middle and late Holocene, and its use accounts for a range of spatial distribution between 150 and 200 km.     

From Old Practices to New Governance Models: Contractual Schemes in Africa’s Political Development

Drawing on various historical documents, the article uses process tracing methods and analytic narratives to establish a relationship between historical contractual practices and state formation in nineteenth-century East Africa. I trace the process through which local political leaders historically sought to secure monopolistic deals over trade with foreign entrepreneurs through incomplete contracts for tangible economic goods (arms and slave trades, manufactured goods) and intangible political goods or services (security, knowledge, independence). By showcasing agents’ bargaining strategies in contractual agreements, the article sheds light on notions of sovereignty and independence articulated through public contracting in Africa’s political development. Historical understandings of notions of independence and sovereignty by procurement practitioners in East Africa provide seeds for thought in controversial debates about government outsourcing today. Is outsourced sovereignty always threatening? Can we outsource sovereignty and remain independent? These are perhaps the most important conceptual queries that make East Africa’s historical contractual experience pertinent today as new public-private partnerships for development, including government outsourcing, increasingly call for the use of private means to solve public problems in the developing countries.     

Late Pleistocene Lithic Procurement and Geochemical Characterization of the Cerro Kaskio Obsidian Source in South‐western Bolivia

Primary questions regarding the foraging behaviour of the first hunter–gatherers who colonized the New World are how they found, procured and utilized high‐quality raw materials for manufacturing stone tools. In this paper, we present evidence from the late Pleistocene site of Cueva Bautista in the highlands of south‐western Bolivia, which demonstrates that a substantial portion of the recovered stone tool assemblage originated in Cerro Kaskio, a recently discovered obsidian source located 15 km south‐west of the site. In addition to describing the geological and geochronological setting, we provide the first geochemical characterization of the Cerro Kaskio source by means of instrumental neutron activation analysis and energy‐dispersive X‐ray fluorescence. Supported on the technological analysis and archaeometric sourcing of the obsidian lithics found in Cueva Bautista, we discuss the nature of the procurement strategies practised by the earliest mobile hunter–gatherers who explored and colonized the Andean highlands. We conclude that opportunistic lithic resource procurement was probably an important component of the first foraging societies that explored the highland Andes.     

Geology and lithic procurement in Upper Palaeolithic Europe: a weights-of-evidence based GIS model of lithic resource potential

In this paper we examine ways to predict the distribution of siliceous rock in Europe, using a Bayesian technique known as ‘Weights-of-Evidence’. We use the technique to classify bedrock geological formations in terms of their likelihood of yielding tool-quality lithic raw materials, and we use the results to re-examine possible causes of a west–east cline in maximum lithic raw material transfer distances observed when comparing sites in both Middle and Upper Palaeolithic Europe. It is evident from our results that there is a decline in abundance of geological formations highly predictive of tool-quality rock along a west–east cline, predominantly reflecting a decrease in abundance of Jurassic and Cretaceous chert-bearing sedimentaries. Our results are consistent with an interpretation of the Upper Palaeolithic record of transfer distances as indicating special-purpose procurement.     

Understanding Prehistoric Lithic Raw Material Selection: Application of a Gravity Model

Provenance studies can tell us which sources of lithic raw material were used in the past, but can they tell us why? After all, many factors can have entered into a person’s choice to use one source rather than another. Those factors can be grouped into two categories, the geologic/geographic characteristics of the source itself (quality, abundance, size of pieces, etc.), and the human factors (direction of travel, time available, social restrictions, etc.). This paper demonstrates how the geologic/geographic characteristics can be quantified and calculated together to give one value, the attractiveness of the source, which can then be used in a gravity model approach to predict which sources ‘should’ have been used more than others. Deviations from the predicted pattern point to situations where the human factors were of greater or lesser importance. The values are also used to delineate geographical areas within which particular sources would be likely to be used (‘areas of influence’), which gives us a useful new way of understanding the landscape within which the prehistoric group lived.     

Physical planning in an era of marketization: conflicting governance perspectives in the Swedish Transport Administration

Planning of transport infrastructure in Sweden has undergone successive legislative changes as well as neoliberal corporatization and marketization reforms in recent years, with a general aim to increase efficiency and effectiveness. This paper presents planning practitioners’ experiences of far-reaching marketization of physical planning practice in line with a strategy within the Swedish Transport Administration (STA) to become a ‘Pure Purchaser’. The strategy implies that all practical planning work should be carried out by procured consultants. The paper follows a qualitative, explorative approach based on document studies and interviews with practitioners actively involved in carrying out physical planning of road and rail investments. The concept of ‘modes of governance’ is applied to highlight and analytically interpret differences in perspectives on efficient and effective governance as expressed in the planning legislation, and the STA marketization strategy, respectively. The empirical results make evident that the recent marketization reforms are generally perceived as strongly and negatively affecting the efficiency and effectiveness of planning practices while also circumscribing professional discretion. The study highlights the importance of specific organization and management perspectives as explanatory factors in studying efficiency and effectiveness of planning practices.     

Missing the boat in lithic procurement: Watercraft and the bulk procurement of tool-stone on the Maritime Peninsula

Recent research has characterized the procurement of lithic raw materials for flaked stone technology as embedded in food procurement activities, and constrained by logistical factors such as mass, time, and energy. Many have assumed that these variables reflect the need for humans to both move themselves to resources, and carry materials with them. This paper explores the implication of these ideas through the development of particular research project in the Maritime Peninsula, in the Northeast of North America. Through this research process, I explore the complex interplay among raw materials, bulk procurement, water transportation, and regional patterning of archaeological lithic assemblages. I initially consider the role of embedded procurement as a structuring mechanism for the relationship between lithic raw-material diversity and catchment, but through a exploration of intersite and inter-feature variability, I consider the role of bulk procurement in this patterning. I conclude that canoes may significantly influence hunter–gatherer lithic procurement, in terms of the extraction of resources, and their reduction and use.     

Obsidian source characterization in the Cordillera Real and eastern piedmont of the north Ecuadorian Andes

Recent research in the Quijos and Cosanga valleys of the eastern piedmont of Ecuador’s Cordillera Real has revealed and substantiated previous knowledge of obsidian sources that are unrelated to obsidian flow systems in the Sierra de Guamaní, Ecuador. Neutron Activation Analysis (NAA) and X-ray Fluorescence (XRF) were carried out on 47 obsidian source samples collected from several contexts in and adjacent to the study area. From samples within the study area three distinct obsidians were characterized: Cosanga A, Cosanga B, and Bermejo. These obsidians originate from a number of obsidian-bearing rhyolitic domes recently identified in the hills west of the Río Cosanga. Extensive survey of these dome localities has identified obsidian cobbles large enough for formal and informal tool manufacture. Beyond the study area, samples were collected and analyzed from the El Tablón source in the Sierra de Guamaní, providing much needed data on this poorly understood source. In addition, a sample from the newly identified Conda Dome source, near the Cotopaxi volcano, was characterized with XRF. All samples were then compared to 57 pre-existing samples from the Mullumica–Callejones, Yanaurco–Quiscatola and Carboncillo sources in the Ecuadoran Cordillera Real, as well as to artifacts from the Sumaco area in the Ecuadorian Amazon. Results of the elemental characterization indicate that the Cosanga Valley, El Tablón and Conda Dome obsidians are chemically distinct. Further, visual characteristics of Cosanga Valley obsidian types are useful in source attribution for the large artifact samples from the region. Finally, obsidian collected from the El Tablón flow suggests that this source may have produced obsidian suitable for tool manufacture.
