Lithic Analysis of an Early Archaic Knapping Area

Abstract

Archaeological excavations at 15LO207 in Logan County, Kentucky documented a lithic reduction area associated with an Early Archaic Kirk Corner Notched component. High densities of flake debris were recovered, along with biface production failures, from this area. Analysis of these materials indicated that lithic manufacture focused on the reduction of early stage bifaces of the local Ste. Genevieve chert into late stage bifaces. These bifaces were transported elsewhere for further reduction and use. In addition, data indicate a staged approach to biface reduction for the Early Archaic.

The Organisation of a Zoo-archaeological Reference Collection of Bird Bones

Abstract

This note describes how we have organised part of our reference collection of bird bones in a series of drawers. The layout takes into consideration a) part of the skeleton (all humeri, for example, are housed together), b) size (smallest species are in the first drawer, larger in the second and so on), and c) taxonomic position (within each drawer specimens within orders, whose labels are colour-coded, are grouped together). Empty cells, reserved for species still missing from the collection, serve as reminders of possible alternative identifications for an archaeological specimen and therefore help to prevent the tendency of forcing identification to what is present in the reference collection.     

Mesoamerican Obsidian Blades: an Experimental Approach to Function

Abstract

The experimental replication and utilization of a sample of 165 obsidian blades is discussed in terms of research design. methodology, and results. Use-wear observed on the blades provides the basis for 1) the identification of wear-pattern “signatures” corresponding to particular modes of use and contact materials, 2) the evaluation of general propositions concerning edge damage on utilized tools, and 3) the determination of the probable function of a sample of prismatic obsidian blades recovered from Patarata 52, a Classic Period residential site located in an estuarine zone of coastal Veracruz, Mexico.

Two levels of functional analysis are discussed: the low-intensity or in-the field study, and the high-intensity analysis, which involves tool replication and use. high-power microscopy , and statistical manipulation with computers. Both approaches are advocated: the choice of one method over the other must be made on the basis of availability of time. money, special skills, and equipment.

Building a Conceptual Approach to Collective Learning: Lessons for Public Policy Scholars

In public policy processes, collective learning among policy actors is important in shaping how these processes unfold and the types of policy outcomes that may result. Despite a widespread interest in learning by policy scholars, researchers face a number of conceptual and theoretical challenges in studying learning across different collective settings within policy processes. In this article, we offer a theoretically grounded approach to defining and understanding collective‐level learning. In defining learning, we first draw out the connection between learning processes and learning products, both cognitive and behavioral. In examining learning processes, we further explore the relationship between individual and collective learning. Then we identify and define the key characteristics of collective settings that will likely influence learning processes. We conclude by offering recommendations for policy scholars to apply this approach in studies of learning across diverse policy contexts.

Prehispanic Dugout Canoes in Mexico: A Typology Based on a Multidisciplinary Approach

Navigation implies a deep knowledge of the environment in which it is practised as well as the development of correlated technologies and techniques. In fact, sailing in lakes, rivers, along coasts or in high seas requires specific skills. This is why watercraft reflect the specific expertise of cultures in relation to the available resources and materials. Navigation as a means of movement and boats as modes of transportation is a well-documented topic in Europe, Asia and the Pacific Ocean, whether focusing on antiquity or the present. Nonetheless, in the New World, especially in Mesoamerica where the Aztec, Tarascan and Mayan Empires flourished, indigenous maritime history has been thoroughly under-investigated. This article explores the first prehispanic dugout canoes of the region, based on a multidisciplinary approach for the Mexico and Pátzcuaro Basins, in the Late Postclassic period (AD 1325-1521). For the first time, a typology of these dugout types is proposed, with a discussion of the importance of dugout canoes as a means of transportation in Mesoamerican civilizations, where wheels and draught animals did not exist.     

Analysis of Dental Cementum Rings as an Approach to Azilian Hunting Strategies

Abstract

Perfected by biologists, the analysis of dental cementum rings allows us to know the precise age of the animals studied as well as their season of death. Cementum deposits are layers of various density formed regularly during the animal's life. Large, translucid deposits (observed with polarized light), growing during the good season (spring, summer, autumn), alternate with thin, opaque ones that grow during the bad season (winter). Used to study two French Azilian sites, La Fru and Campalou, this method gives us a better understanding the hunting behaviour of these two human groups. Thus, the Azilian hunters who established their camp in the La Fru and Campalou rockshelters hunted around the site, killing ibex. However, these two groups of predators preferred red deer. Taking advantage of the hunting opportunities offered by the environment, hunters at both sites made opportune captures to the detriment of summer herds of hinds and young. Also, at Campalou, they continued their predation during the rut, concentrating on young animals, probably young males temporarily alone because of the mating season.     

Experimental Investigation on the Seismic Behavior of the Semi-Rigid One-Way Straight Mortise-Tenon Joint of a Historical Timber Building

ABSTRACT

This article aims to disclose that the deformation and damages of the one-way straight mortise-tenon (OWSMT) joint, the key force transmission connection of traditional wood buildings, lead to a significant reduction in structural safety of ancient timber structure. For this purpose, the damage of mortise joint in practical engineering wassimulated by controlling the gap and width between mortise and tenon. A total of 23 groups of scaled 1:2 OWSMT joint specimens were fabricated and tested subjected to cyclic loadings, and the hysteretic curves of OWSMT joint with different damage degrees were obtained. Through skeleton curves, stiffness degradation curves, and equivalent viscous damping curves of the OWSMT joint, the seismic performance of damaged wood joints was quantitatively analyzed. The results show that, with the increase in the gap between the tenon and the mortise, the slip between them became increasingly obvious, the fullness and peak of the hysteresis curve gradually decreased, the gradient of the skeleton curve also dropped, and both the stiffness degradation curve and the equivalent viscous damping curve are gradually reduced. The research findings shed new light on the seismic assessment of aging timber buildings.     

Community as a Policy Instrument: A Comparative Analysis

Over recent decades. "community" has been a powerful theme in social policy development not only in the United States but elsewhere in North America and Europe as well. Existing analyses of the concept, however, tended to approach it more from philosophical and sociological perspectives than from the standpoint of policy analysis. This article examines the uses of community as a policy instrument, considering its diverse applications us policy objective, policy means, and policy rhetoric. A cross-section of major community-oriented policies in the United States and Quebec is analyzed, providing a basis file policy-level, regime-level, and political culture comparison. Identifying the key components that community policies may incorporate, we propose a schema for systematically describing deferent types of interventions. Finally. we review the difficulties encountered in implementing policies with a community orientation and the need to avoid simplistic judgments of success and failure.

Zapotec innovation in a Mexican village: Building an autonomous mobile network

In 2013, a Zapotec village in the Mexican state of Oaxaca drew international attention when its citizens successfully created an autonomous mobile phone network. Using open‐source software and with technical assistance from an NGO (non‐governmental organization), the people of Talea de Castro obtained antennae, a base station and software that enabled them to build a fully functional mobile network with global reach. This article examines theoretical questions about the nature of innovation and the conditions that might help promote it. It also places the network in broad historical and social contexts. The article reviews the political, legal and technical processes by which villagers were able to create the network. For many years, Talea has been a centre of technological creativity and experimentation. The network might be seen as the village's latest innovation in a centuries‐long process in which creative problem‐solving is integrated with indigenous patterns of mutual aid, reciprocal labour and cooperativism. The article concludes with a discussion of the challenges facing the network and its users.     

The Effect of Stiffened Floor and Roof Diaphragms on the Experimental Seismic Response of a Full-Scale Unreinforced Stone Masonry Building

An extensive experimental program was carried out at EUCENTRE, within a research project on the evaluation and reduction of the seismic vulnerability of stone masonry structures. The main part of the experimental program has been devoted to the shaking table tests on three full-scale, two-story, single-room prototype buildings made of undressed double-leaf stone masonry. The first building tested was representative of existing unreinforced stone masonry structures with flexible wooden diaphragms, without any specific anti-seismic design nor detailing. In the second and third buildings, strengthening interventions were simulated on structures theoretically identical to the first one, improving wall-to-floor and wall-to-roof connections and increasing diaphragm stiffness. In particular, in the third specimen, steel and r.c. ring beams were used to improve the diaphragm connection to the walls and collaborating r.c. slab and multi-layer plywood panels were used to stiffen floor and roof diaphragms, respectively. This article describes the strengthening interventions applied to the third building prototype and presents the experimental results obtained during the shaking table tests. The results obtained permitted the calibration of a macroelement model representative of the nonlinear behavior of the structure.
