The Emergence of Pressure Blade Making
Human development is a long and steady process that began with stone tool making. Because of this skill, humans were able to adapt to climate changes, discover new territories, and invent new technologies. "Pressure knapping" is the common term for one method of creating stone tools, where a larger device or blade specifically made for this purpose is use to press out the stone tool. Pressure knapping was invented in different locations and at different points in time, representing the adoption of the Neolithic way of life in the Old world. Recent research on pressure knapping has led for the first time to a global thesis on this technique. The contributors to this seminal work combine research findings on pressure knapping from different cultures around the globe to develope a cohesive theory. This contributions to this volume represents a significant development to research on pressure knapping, as well as the field of lithic studies in general. This work will be an important reference for anyone studying the Paleolithic, Mesolithic, and Neolithic periods, lithic studies, technologies, and more generally, cultural transmission.
Conflicts Between Biodiversity Conservation and Humans
This book takes readers on a journey through the history of water in the Coahuila desert. It starts by describing the beauty and mysteries of the landscape, and then explores the rock art of the original desert cultures in Coahuila, offering readers a glimpse of the sacred nature of water in the desert, as well as the rituals surrounding it. Moving on to the colonial times and the post- independence development of the region, it discusses early water management, and explores how water is managed in modern times, as well as the legal complications of the law, and how these faulty laws, designed for less arid regions, have affected a highly diverse wetland, the Cuatro Ciénegas oasis. The book then examines the biological consequences of the water loss for the aquatic plants and animals in Churince – a now extinct system within Cuatro Ciénegas. Further, it addresses how even bacteria can become extinct in this hyper-diverse microbial oasis. Lastly, after this despair and sense of loss, the book provides hope, offering suggestions for how we can transform the future, from a social and educational point of view as well as through good science and changes in policy.

Lithic Technologies in Sedentary Societies
Lithic Technologies in SedentarySocieties examines lithic technology from ancient societies in Mesoamerica, the Near East, South Asia, and North America, showcasing the important contributions in-depth lithic analysis can make to the study of sedentary societies around the world. Using cutting-edge analytical techniques these case studies address difficult anthropological questions concerning economic, social, and political issues, as well as global trends in lithic production. Lithic analysis focused on sedentary societies, especially in places like Mesoamerica, has previously been neglected mostly because of the high frequency of informal tools, but such bias limits the ways in which both ...
Edward Palmer's Arkansaw Mounds
During the 1880s a massive scientific effort was launched by the Smithsonian Institution to discover who had built the prehistoric burial mounds found throughout the United States. Arkansaw Mounds tells the story of this exploration and of Edward Palmer, one of the nineteenth century’s greatest natural historians and archaeologists, who was recruited to lead the research project. Arkansas was unusually rich in prehistoric remains, especially mounds, and became a major focus of the study. Palmer and his team of researchers discovered that the mounds had been built by the ancestors of the historic North American Indians, shattering the then-popular theory that a lost non-Indian race had built them.

Recent Advances In Density Functional Methods, Part Ii
Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as the computational methodology of DFT.This Part II expands on the methodology and applications of DFT. Some of the chapters report on the latest developments (since the publication of Part I in 1995), while others extend the applications to wider range of molecules and their environments. Together, this and other recent review volumes on DFT show that DFT provides an efficient and accurate alternative to traditional quantum chemical methods. Such demonstration should hopefully stimulate frutiful developments in formal theory, better exchange-correlation functionals, and linear scaling methodology.
