Healthcare students support opt-out organ donation for practical and moral reasons
BACKGROUND AND PURPOSE: Changes to deceased organ donation policy in the USA, including opt-out and priority systems, have been proposed to increase registration and donation rates. To study attitudes towards such policies, we surveyed healthcare students to assess support for opt-out and priority systems and reasons for support or opposition. METHODS: We investigated associations with supporting opt-out, including organ donation knowledge, altru…
Last Glacial Maximum Microblade Production at Shizitan 29 and its Implications for North China Pressure Technology
A techno-functional approach applied to the lithics of the Late Upper Palaeolithic Shizitan 29 site allows the identification of previously unrecognized technical features of microblade pressure production and new behavioral understanding of its evolution beginning ca. 26,000 cal b.p. These technical features may relate to the evolution of so-called boat-shaped cores, including the development of two blade scar sequences and the 8-like contour of…
Arqueología del urbanismo de Santafé de Bogotá
A raíz de las recientes excavaciones realizadas en la que fuera la Calle Real de Santafé de Bogotá (Colombia), se pusieron en evidencia distintos sistemas de cañe- rías de aguas consumibles y residuales. Estos hallazgos condujeron a la realización de los análisis tipológico y arqueométrico de las distintas estructuras excavadas, los cuales permitieron identificar sus funciones y periodos de construcción. Con base en estos análisis, también fue po…
Micromorphological and FTIR analysis of the Upper Paleolithic early pottery site of Yuchanyan cave, Hunan, South China
The site of Yuchanyan cave (Hunan Province, China) contains evidence for some of the earliest‐known (ca. 18,000 cal BP) pottery in the world alongside a typical South China Upper Paleolithic cobble tool (chopper) industry. Here we present the results of a micromorphological study of the deposits with particular attention to site formation processes and recognizable human activities. Our study reveals that the majority of the sediments are anthrop…

Were bamboo tools made in prehistoric Southeast Asia? An experimental view from South China
The Beginnings of Agriculture in China
By 9000 cal BP, the first sedentary villages, marking the Early Neolithic, are present in Northeast China, North China, and the Middle and Lower Yangtze regions, but plant and animal domesticates do not make a substantial contribution to subsistence until after several more millennia, when domesticated millet or rice agricultural production is finally in place. While archaeobotanical approaches have been the primary focus of recent studies, this …
Radiocarbon dating of charcoal and bone collagen associated with early pottery at Yuchanyan Cave, Hunan Province, China
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments based on analyses of charcoal and bone collagen. The bes…
