From the preface: "Mr. Renz has assembled a friendly read from the standpoint of a serious, well-read amateur. His work promises to be an excellent educational guide for those interested in paleontology or seeking information about their fortuitous discovery of fossil remains."--James S. Dunbar, archaeological field supervisor, Florida Bureau of Archaeological Research With boundless enthusiasm, Mark Renz stumbles onto the skeletal remains of fierce saber-toothed cats, gentle sea cows, massive mammoths and mastodons, Volkswagen-size armadillos, and an ancient 5-ton giant ground sloth, and then shares these experiences in a humorous, illustrated book for beginning fossil collectors. Want to look for fossils yourself but not sure how to get started? Renz tells how and where to hunt and how to preserve your finds for another million years, and he provides more than 250 photographs that help you to identify those bones and teeth and distinguish a prehistoric bison from a farmer's lost cow. He also provides information about what's there to be found, the hurdles and hazards to be overcome, and the legalities to be observed. Guided by an appreciation for the professional paleontologist and also for the laws that regulate his hobby, Renz explains, for example, why it is okay to dig for fossils in a state-owned creek bed (providing one possesses a state permit and does not dig in a state park), and why it is illegal to engage in the same activity in search of artifacts. With writing that's free of technical jargon but full of love for fossiling, this illustrated book will inspire you to explore the huge number of rich fossil deposits in Florida that can be found with just a shovel and a keen eye.
This book presents the multidisciplinary results of an extensive underwater excavation in north Florida which yields the most complete results of interactions between early Paleoindians and late Pleistocene megafauna, especially Mammut americanum (American Mastodon), in a rich environmental context in eastern North America. It provides fundamental insights into two urgent issues: "The Peopling of the Americas"; and "The Extinction of the Megafauna." The authors describe and illustrate their unique methods of precise underwater excavations. They show how these techniques allowed them to collect a diversity of zoological, botanical and cultural material with outstanding organic preservation. This wealth of prehistoric evidence was recovered during twenty years of delving into an ancient sinkhole in the bottom of the Aucilla River. The nearly continuous sequence of fine-grained sediments, with an abundance of carbon dates, place the climatic and environmental history of this area in a global context of late glacial climatic cycles. The deepest strata produce clear evidence that the first Floridians lived and hunted here some 14,000 years ago, indicating that this southeastern culture preceded classic Clovis culture in western North America. Clever studies of stable isotopes tell that the Mastodons migrated north out of Florida into glacial terrain during the winter and spring and their digesta, which also contain steroids and epithelial cells, display a rich summer diet. The last section of the book provides a wealth of new evidence from the early Holocene about the flora and climate and how early Archaic people subsisted after the megafauna became extinct. An excellentcolor photo section expresses the unique setting and adventure of this project, extensively supported by National Geographic Society. "A monument of interdisciplinary scientific analysis and reporting, and absolutely essential reading for anyone interested in the early human settlement of the Americas." David G. Anderson, Department of Anthropology, The University of Tennessee, Knoxville, TN, USA. "An excellent array of interdisciplinary studies conducted at an important site offering new and exciting clues on the origins of the First Americans" Dr. Stanford, Department of Archeology, Smithsonian Institution, Washington, DC, USA

Heidegger, Ethics and the Practice of Ontology presents an important new examination of ethics and ontology in Heidegger. There remains a basic conviction throughout Heidegger's thought that the event by which Being is given or disclosed is somehow 'prior' to our relation to the many beings we meet in our everyday lives. This priority makes it possible to talk about Being 'as such'. It also sanctions the relegation of ethics to a secondary position with respect to ontology. However, Heidegger's acknowledgement that ontology itself must remain intimately bound to concrete existence problematises the priority accorded to the ontological dimension. David Webb takes this bond as a key point of reference and goes on to develop critical perspectives that open up from within Heidegger's own thought, particularly in relation to Heidegger's debt to Aristotelian physics and ethics. Webb examines the theme of continuity and its role in the constitution of the 'as such' in Heidegger's ontology and argues that to address ontology is to engage in an ethical practice and vice versa.
The Birth of Physics represents a foundational work in the development of chaos theory from one of the world's most influential living theorists, Michel Serres. Focussing on the largest text still intact to reach us from the Atomists - Lucretius' De Rerum Natura - Serres mobilises everything we know about the related scientific work of the time (Archemides, Epicurus et al) in order to demand a complete reappraisal of the legacy. Crucial to his reconception of the Atomists' thought is a recognition that their model of atomic matter is essentially a fluid one - they are describing the actions of turbulence, which impacts our understanding of the recent disciplines of chaos and complexity. It explains the continuing presence of Lucretius in the work of such scientific giants as Nobel Laureates Schroedinger and Prigogine. This book is truly a landmark in the study of ancient physics and has been enormously influential on work in the area, amongst other things stimulating a more general rebirth of philosophical interest in the ancients.

Two rather different elements combine to explain the origin of this volume: one scientific and one personal. The broader of the two is the scientific basis-the time for such a volume had arrived. Geology had made remarkable progress toward an understanding of the phys ical history of the Caribbean Basin for the last 100 million years or so. On the biological side, many new discoveries had elucidated the distributional history of terrestrial orga nisms in and between the two Americas. Geological and biological data had been combined to yield the timing of important events with unprecedented resolution. Clearly, when each of two broad disciplines is making notable advances and when each provides new insights for the other, the rewards of cross-disciplinary contacts increase exponentially. The present volume represents an attempt to bring together a group of geologists, paleontologists and biologists capable of exploiting this opportunity through presentation of an interdisciplinary synthesis of evidence and hypothesis concerning interamerican connections during the Cretaceous and Cenozoic. Advances in plate tectonics form the basis for a modern synthesis and, in the broadest terms, dictate the framework within which the past and present distributions of organisms must be interpreted. Any scientific dis cipline must seek tests of its conclusions from data outside of its own confines."

In 1980, Furchgott and Zawadzki demonstrated that the ability of a blood vessel to relax to acetylcholine is entirely dependent upon the presence of an intact endothelium b1. This startlingly simple and elegant observation heralded a decade of basic research into endothelium-derived vasoactive factors (EDRF). Initially, interest focused on Furchgott's endothelium-derived relaxing factor, which was later identified as the extremely simple molecule, nitric oxide [21. However, bioassay systems suggested the presence of other dilator and constrictor factors. Many of these additional putative factors remain elusive but one constrictor factor was revealed to the world in an impres- sively complete piece of science published in 1988. Yanagisawa, Masaki and colleagues [31 demonstrated the synthesis of a twenty one amino acid peptide which accounted for the constrictor activity found in the supernatant of endothelial cells. They identi- fied its structure, synthesised the peptide, showed its biological activity in vitro and in vivo, proposed mechanisms of action and cloned and sequenced the gene. They named the factor endothelin. The identification of nitric oxide and endothelin has also rekindled interest in established endothelium-derived mediators, including the prostanoids and other arachidonic acid metabolites, and has led to exploration of the possible roles of oxygen radicals such as superoxide. The vascular endothelium has become a major focus for research into disease states or cardiovascular risk factors associated with abnormal vascular tone or reactivity, alterations in cellular adhesion to the vessel wall, increased smooth muscle cell growth and the chronic process of atherogenesis.
What should we make of the return to the sacred evidenced by the
new vitality of churches, sects, and religious beliefs in many
parts of the world today? What are the boundaries between the
essential traits of religion and those of ethics and justice? Is
there a "truth" to religion? This remarkable volume includes
reflections on such questions by three of the most important
philosophers of our time--Jacques Derrida, Gianni Vattimo, and
Hans-Georg Gadamer. Together with other distinguished thinkers,
they address a wide range of questions about the meaning, status,
and future prospects of religion.

Psychology Classics: Significant Aspects of Client-Centered Therapy
Town and country planning has never been more important to the UK, nor more prominent in national debate. Planning generates great controversy: whether it s spending 80m and four years inquiry into Heathrow s Terminal 5, or the 200 proposed wind turbines in the Shetland Isles. On a smaller scale telecoms masts, take-aways, house extensions, and even fences are often the cause of local conflict. " Town and Country Planning in the UK" has been extensively revised by a new author group. This 15th Edition incorporates the major changes to planning introduced by the coalition government elected in 2010, particularly through the National Planning Policy Framework and associated practice guidance and the Localism Act. It provides a critical discussion of the systems of planning, the procedures for managing development and land use change, and the mechanisms for implementing policy and proposals. It reviews current policy for sustainable development and the associated economic, social and environmental themes relevant to planning in both urban and rural contexts. Contemporary arrangements are explained with reference to their historical development, the influence of the European Union, the roles of central and local government, and developing social and economic demands for land use change. Detailed consideration is given to the nature of planning and its historical evolution the role of the EU, central, regional and local government mechanisms for developing policy, and managing these changes policies for guiding and delivering housing and economic development sustainable development principles for planning, including pollution control the importance of design in planning conserving the heritage community engagement in planning The many recent changes to the system are explained in detail the new national planning policy framework; the impact of the loss of the regional tier in planning and of the insertion of neighbourhood level planning; the transition from development control to development management; the continued and growing importance of environmental matters in planning; community engagement; partnership working; changes to planning gain and the introduction of the Community Infrastructure Levy; and new initiatives across a number of other themes. Notes on further reading are provided and at the end of the book there is an extensive bibliography, maintaining its reputation as the bible of British planning."
