Evolution of Environments and Hominidae in the African Western Rift Valley
Exploration of an important paleoanthropological site in the Rift Valley of eastern Zaire, from over two million years ago to the present. The Semliki Research Expedition, directed by Noel T. Boaz, Curator of Biological Anthropology at the Virginia Museum of Natural History, has investigated the upper reaches of the Semliki River Valley since 1982. Nineteen papers by members of the Expedition present & discuss the geology, paleoecology, paleontology, & archaeology of the site. Includes documentation of presence of early hominids in the Western Rift over two million years ago; an extensive fossil flora, the first recovered from this area of Pliocene Africa & one that shows the nearby presence of dense, lowland forest; an extensive vertebrate & invertebrate fauna that documents the presence of savannas & which includes evidence of extensive evolutionary radiations of fish & molluscan species; the first relatively complete human fossil crania from the highest statigraphic levels; studies on the archaeology of the Age of Metals, ethnoarchaeology among the tribal groups inhabiting the area today, & actualistic studies, relevant to paleoanthropological interpretation.
Entrepreneurship and Economic Growth
By serving as a conduit for knowledge spillovers, entrepreneurship is the missing link between investments in new knowledge and economic growth. The knowledge spillover theory of entrepreneurship provides not just an explanation of why entrepreneurship has become more prevalent as the factor of knowledge has emerged as a crucial source for comparative advantage, but also why entrepreneurship plays a vital role in generating economic growth. Entrepreneurship is an important mechanism permeating the knowledge filter to facilitate the spill over of knowledge and ultimately generate economic growth.
Mechanisms of Invasion and Metastasis
This book covers important biological, immunological, and molecular information essential for understanding the rationale and results of experiments and clinical observations on cell-cell and cell substrate adhesion; hydrolytic activities, cell motility; immunological and other host elements of the host-tumor ecosystem (at different sites of the metastic process); genetic and epigenetic elements of the acquisition and the expression of invasive phenotypes. 38 tables and 60 computer-drawn figures provide comprehensive overviews, and a methodological chapter emphasizing the differences and similarities between assays and their relevance for natural situations has also been included. Clinical and experimental cancer researchers, as well as as post-graduate students interested in cancer research, will find this book to be an indispensable reference resource.
Drawing Futures
Drawing Futures brings together international designers and artists for speculations in contemporary drawing for art and architecture.Despite numerous developments in technological manufacture and computational design that provide new grounds for designers, the act of drawing still plays a central role as a vehicle for speculation. There is a rich and long history of drawing tied to innovations in technology as well as to revolutions in our philosophical understanding of the world. In reflection of a society now underpinned by computational networks and interfaces allowing hitherto unprecedented views of the world, the changing status of the drawing and its representation as a political act ...
