A Paleoindian campsite has been uncovered in stratified prehistoric deposits in Caverna da Pedra Pintada at Monte Alegre in the Brazilian Amazon. Fifty-six radiocarbon dates on carbonized plant remains and 13 luminescence dates on lithics and sediment indicate a late Pleistocene age contemporary with North American Paleoindians. Paintings, triangular bifacial spear points, and other tools in the cave document a culture distinct from North American cultures. Carbonized tree fruits and wood and faunal remains reveal a broad-spectrum economy of humid tropical forest and riverine foraging. The existence of this and related cultures east of the Andes changes understanding of the migrations and ecological adaptations of early foragers.
The Collaborative Initiative on Fetal Alcohol Spectrum Disorders (CIFASD) was created in 2003 to further understanding of fetal alcohol spectrum disorders. Clinical and basic science projects collect data across multiple sites using standardized methodology. This paper describes the methodology being used by the clinical projects that pertain to assessment of children and adolescents. Domains being addressed are dysmorphology, neurobehavior, 3D facial imaging, and brain imaging.
Research-networking tools use data-mining and social networking to enable expertise discovery, matchmaking and collaboration, which are important facets of team science and translational research. Several commercial and academic platforms have been built, and many institutions have deployed these products to help their investigators find local collaborators. Recent studies, though, have shown the growing importance of multiuniversity teams in science. Unfortunately, the lack of a standard data-exchange model and resistance of universities to share information about their faculty have presented barriers to forming an institutionally supported national network. This case report describes an initiative, which, in only 6 months, achieved interoperability among seven major research-networking products at 28 universities by taking an approach that focused on addressing institutional concerns and encouraging their participation. With this necessary groundwork in place, the second phase of this effort can begin, which will expand the network's functionality and focus on the end users.
The early Neolithic of the west Mediterranean
The archaeological complex known as the early Neolithic in the west Mediterranean represents the arrival of Neolithic traits in western Europe. Dating to around 5000 BC (Evin 1987), this complex is marked by the appearance of pottery, ground stone tools, and transvcrse projectile points. It continues for about a millennium until middle Neolithic villages, such as Villeneuve-Toulousane, begin to appear. The early Neolithic is characterized by a transitional agricultural subsistence economy. At Aude Valley cave sites, domesticated sheep first appear in aceramic Mesolithic layers with typical Tardenoisian tool assemblages and fauna (Geddes 1983). Examination of these sheep remains show that this strain originated in the Near East (Geddes 1985). Early Neolithic deposits (as defined by the presence of ceramics) are found at many of the same Mesolithic sites and contain similar lithic assemblages as well as a continuation of mixed hunted and domesticated fauna. The presumably novel open-air coastal sites of this period, such as Leucate-Corrège (Guilaine et al. 1984), also appear to represent a mixed economy. Since there is no sudden apparent shift in settlement pattern or economy associated with the early Neolithic, this period appears to be best characterized as a time of gradual transition from hunting and gathering to agriculture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
