What Explains the Carcass Field Processing and Transport Decisions of Contemporary Hunter-Gatherers? Measures of Economic Anatomy and Zooarchaeological Skeletal Part Representation

This paper uses rationale derived from central place foraging models to explore the factors that guide the carcass processing and transport decisions of modern hunters. Using data derived from butchering experiments, I test different economic indices that purportedly reflect the field processing and transport decisions of contemporary African Hadza hunter-gatherers. The results show that no single index predicts part processing and transport for the species examined in this analysis. Processing and transport decisions are, however, patterned in ways that are consistent with theoretical predictions. While similar processes likely guide carcass treatment and transport decisions among all hunter-gatherers, different ecological, social, and historical constraints define the range of solutions to problems involving carcass treatment. In this specific example, intertaxonomic differences in carcass size and bone properties constrain how the trade-offs between field processing and transport costs are resolved. I conclude by suggesting ways in which analysts might make use of central place foraging rationale and models to explain variation in skeletal representation and abundances across time and space.

Lower Pecos and Coahuila peyote: new radiocarbon dates

Peyote, a psychoactive cactus native to the Chihuahuan Desert, has been preserved from excavations at only two archaeological sites: Shumla Caves in the Lower Pecos region of southwest Texas and shelter CM-79 near Cuatro Ciénegas in Coahuila, Mexico. We determined three indistinguishable radiocarbon ages of 5160 ± 45, 5200 ± 35, and 5210 ± 35 ¹⁴C years BP, yielding a mean age of 5195 ± 20 ¹⁴C years BP for the three specimens from Shumla Caves. For one of the Cuatro Ciénegas specimens we obtained the first direct radiocarbon date of 835 ± 35 ¹⁴C years BP. This study demonstrates the use of peyote by inhabitants of the Lower Pecos region of the Chihuahuan Desert about 6000 calendar years ago, and confirms its use by inhabitants of the Cuatro Ciénegas region of the Chihuahuan Desert in Late Prehistoric times. The Shumla Caves' specimens are composed of an aggregate of ground peyote mixed with other plant material, i.e., they appear to be manufactured peyote effigies, and are definitely not intact peyote buttons.     

The substance of sexual difference: change and persistence in representations of the body in eighteenth-century England

The claims of Thomas Laqueur for a shift from a one-sex to a two-sex model of sexual difference are incorporated into many recent histories of gender in England between 1650 and 1850. Yet the Laqueurian narrative is not supported by discussions of the substance of sexual difference in eighteenth-century erotic books. This article argues that different models of sexual difference were not mutually exclusive and did not change in linear fashion, but that the themes of sameness and difference were strategically deployed in the same period. Thus, there was an enduring synchronic diversity which undermines claims for linear transformation.     

The Implications of Parenting Standards in Child Protection: A Paradox in Disability Policy

Contemporary parenting standards in the field of child protection produce a paradox in disability policy. Focusing on the protections necessary for child safety, child protection workers are apt stereotypically to discount the abilities of parents with disabilities to raise their children. This situation runs a wide spectrum. It includes parents fully capable of parenting with no outside assistance who are nevertheless denied their children on the basis of completely baseless stereotypical assumptions. It includes parents who are mentally fully capable of parenting, but who are denied the necessary personal assistance services to perform the physical tasks of child care. This article, however, focuses on yet another situation: parents with mental, emotional, or cognitive disabilities who, without assistance to perform the cognitive tasks necessary for safely raising children, could neglect their children. It discusses this situation in light of the Americans with Disabilities Act and various state laws that protect the civil rights of persons with disabilities.

A preliminary study of patterns of replication in Scoring linear enamel hypoplasias

In order to investigate replicability in scoring linear enamel hypoplasias 59 anterior teeth were evaluated by three observers. Hypoplasias were identified with low-power microscopy and by the unaided eye. Location on the tooth was determined through caliper and micrometer measurement as well as assignment to tooth ‘thirds’. Hypoplasia size was determined through measurement of episode width and comparison with a cast designed to categorize types of hypoplasia severity. Intra-observer analysis showed consistent scoring of about 65 per cent of individual hypoplasias between rounds, with high replicability in episode location, size and severity using all methods tested. Inter-observer error was similarly low for episode size and location, but consistent scoring of individual hypoplasias between observer pairs ranged between 21 and 39 per cent. It is likely that the most important factor in the low level of replicability is the slight size of the majority of hypoplasias involved. Thus, the results suggest that further work should be directed toward developing the minimum threshold for scoring episodes. Other issues include measures to control ‘drift’ in scoring procedures over time, and procedures to score large cervical hypoplasias in canines, which can appear as multiple episodes with magnification. Among the various scoring methods tested, determination of episode location was highly replicable using all three techniques. Episode width was also highly replicable using the micrometer, but the cast association proved less successful.
