The first direct evidence of pre-columbian sources of palygorskite for Maya Blue

Maya Blue, a nano-structured clay–organic complex of palygorskite and indigo, was used predominantly before the Spanish Conquest. It has fascinated chemists, material scientists, archaeologists and art historians for decades because it is resistant to the effect of acids, alkalis, and other reagents, and its rich color has persisted for centuries in the harsh tropical climate of southern Mesoamerica. One of its components, palygorskite, is part of modern Maya indigenous knowledge, and ethnohistoric and archaeological data suggest that its modern sources were probably utilized in Prehispanic times. Yet no direct evidence verifies that palygorskite was actually mined from these sources to make Maya Blue. Here we characterize these sources compositionally, and compare our analyses to those of Maya Blue from Chichén Itzá and Palenque. We demonstrate that the palygorskite in most of these samples came from modern mines, providing the first direct evidence for the use of these sources for making Maya Blue. These findings reveal that modern Maya indigenous knowledge about palygorskite, its mining, and its source locations, is at least seven centuries old.     

Chippewa Land Losses

The account of Chippewa Indian confinement to reservations because of government "treaties" is both familiar and tragic. Not only have such treaties resulted in the alienation of Indian lands, but through subsequent enactment of a series of laws governing Indian reservations much of the remaining reservation land was also permitted to pass into non-Indian hands. Today Chippewa reservations include some 1,800,000 acres and are rather prominent features on United States maps, yet approximately 70% of this land is owned by non-India     

A Preliminary Scheme for the Economic Regionalization of Cuba

The authors propose a scheme of economic regionalization for Cuba, based on Soviet Marxist principles. These include the idea of objective existence of a region, independently of man's will; the need for considering future developmental prospects; energy supply; the prerequisites for integrated development of the regional economy; the presence of a regional specialization; maximum promotion of a geographical division of labor, and the factor of the country's defense capability. The resulting system of six regions in described.     

Putting Religion First

Abstract

This paper examines a version of the religious violence thesis drawn from William Cavanaugh's critical diagnosis of it, and particularly the characterization of some of its proponents that religion is uniquely divisive and, consequently, a unique cause of conflict and violence. According to one representative model advanced by Martin Marty, Mark Juergensmeyer, and others, religion is an inherently disunifying phenomenon because it uniquely enables sacred and exclusive bonds that nurture antagonistic proclivities toward those outside that bond. This paper presents some viable counterexplanations for this kind of phenomena that provide a sufficient basis for questioning the core thread of the thesis.     

Endangered species,archaeology, and stable isotopes: huemul (Hippocamelus bisulcus) isotopic ecology in central-western Patagonia (South America)

The management and conservation of animal species should be based upon a long-term analysis that considers its geographical distribution and feeding patterns. The study of carbon and nitrogen stable isotopes on skeletal remains provides a quantitative approach to the paleodietary reconstructions and constitutes a potent tool for comparing behavioral aspects of the fauna. In this paper we present the first set of isotopic values for modern and archaeological samples of Huemul (Hippocamelus bisulcus) from the forests of Central-western Patagonia, Chile. Contrary to initial expectations, our analysis indicates that there is no evidence of an important incidence of the canopy effect on the δ¹³Ccollagen values, which we suggest is due to an ecological selection that drives the huemul to focus its predation on open sectors within the forest. On the other hand, a wide range of δ¹⁵Ncollagen values for huemul was verified. This could reflect the N impoverishment of the forest soils and provide an interesting ecological indicator. The long-term information offered by the archaeological record provides the necessary context for decision-making conducive towards the preservation of Hippocamelus bisulcus in Patagonia.     

Iberian seventh-born children,werewolves, and the dragon slayer: A case study in the comparative interpretation of symbolic praxis and fairytales

This article examines an obscure custom found in Iberian ethnography: that of having one's eldest children serve as godparents for their own youngest siblings, starting with the seventh. The paper's main working hypothesis is that this custom is to be understood in the context of underlying conceptions that fairytales convey in a symbolical guise. The argument highlights the relationship of examined notions with the “Dragon Slayer” theme, to bring out stable themata concerning ontological complexity and metamorphosis, in the light of which the Iberian custom is interpreted.
