Metapodial asymmetry in draft cattle

Traction work by oxen has been well documented in various pictorial and written sources throughout human history. Analysis of metapodial dimensions has been carried out with the aim of quantifying asymmetry related to sexual dimorphism, body size and possibly heavy duty traction work. A modern reference sample of 103 animals from Hungary and Rumania has been used for this purpose. Bone measurements were correlated with bone density and morphological characteristics in order to make the results applicable for the identification of remains from draft cattle in archaeozoological assemblages. Asymmetry is more pronounced in the thoracic extremity and metacarpals of older or heavier animals, sometimes showing excessive widening of the third, medial ray within the fused bone. Relative broadening is also intensive in the distal end of medial metatarsals of cows and oxen. The bone mineral content of the medial carpal region attains mature density first. The weight of phalanges increases for a longer time in the laterally located toes.     

Low-Fired Earthenwares in the African Diaspora: Problems and Prospects

Local earthenware associated with enslaved African populations in the Americas, variously called Colono-Ware, Afro-Caribbean Ware. Yabbas, and Criollo ware, has received considerable attention from researchers. What unifies this disparate group of ceramics is not method of manufacture, design and decoration, or even form and function but the association or potential association with African diaspora populations. The ceramics incorporate some skills and techniques possibly brought by African potters to the Americas, as well as skills reflecting European and Native American traditions, and local adaptations in form, function, and manufacture. Analogies linking African ceramic traditions to American industries have at times been employed uncritically and have relied on generalized characteristics to infer overly specific meanings. With particular reference to low-fired earthenwares from Jamaica, this paper examines the historical and cultural context of these ceramics and the methodological and theoretical problems faced in their interpretation.     

The Archaeology of El Niño Events and Other “Natural” Disasters

Archaeological research on disasters has increased substantially since Sheets's 1980 review of the topic, and with heightened media coverage and funding for the study of such events, archaeological interest will continue to grow. This paper examines how prehistorians have incorporated disasters into their research since 1980, using the literature on El Niño as an illustrative case, and assesses this work in relation to geographical approaches to disaster as well as concepts that have been developed within the new ecologies.     

RESIDENTIAL SORTING AND ENVIRONMENTAL EXTERNALITIES: THE CASE OF NONLINEARITIES AND STIGMA IN AVIATION NOISE VALUES

This paper explores the sorting process in response to differing levels of aviation noise exposure in a housing market. Spatiotemporal hedonic pricing (HP) and stated choice (SC) results reflect nonlinearities and stigma. The HP models reveal nonlinear noise depreciation increasing from 0.40 to 2.38 percent per decibel as noise increases, while the SC noise values are lower in an area with high long‐term noise exposure. These nonlinearities are attributed to the spatial sorting of noise tolerant individuals. HP results from the same “noisy” area show a “stigma” from noise during the first year after the complete removal of aviation noise.     

THE URBAN–RURAL GAP IN UNIVERSITY ATTENDANCE: DETERMINANTS OF UNIVERSITY PARTICIPATION AMONG CANADIAN YOUTH

Based on existing work, there are clear differences in the incidence of degree holders across the urban–rural hierarchy in favor of large urban areas. In large part, this gradient can be traced to the higher probability of obtaining a degree among residents of larger urban centers. Utilizing data from the Youth in Transition Survey (YITS), this paper explores factors that may account for university participation among Canadian youth. It asks whether this difference is due to local access to universities, family characteristics (e.g., parental income, education, and immigrant status), and local labor market characteristics that may increase the incentive for urban youth to attend university.
