In the later part of the 20th century, the United States experienced a remarkable surge in public interest toward medicinal and aromatic crops and this trend continues. This consumer interest helped create a significant demand for plants with culinary and medicinal applications as the public discovers their benefits for a wide range of applications. Consequently, this consumer call has generated a huge demand on farmers, but has also provided opportunities for new agricultural crops to support both fresh and dry raw material markets. Processing raw materials for end use by consumers introduces even more variables at all levels from harvesting to final desired product. Maintaining quality and authenticity throughout this process has inspired farmers, processing facilities, and regulatory agencies to adopt new practices and new laws to maintain safety and quality. Maintaining this quality and authenticity is often made possible using analytical methods for quality control, which subsequently triggered a demand for both regulatory agencies and scientists throughout the world. For aforementioned reasons, it is imperative that scientists continue to explore related topics from the field to the final consumer product. This book touches on many of the issues currently being addressed by scientists working to produce the desired consumer product while maintaining authenticity and quality and environmental stewardship.
The world-wide sales of polysiloxanes or silicones at the beginning of this new millennium is approximately $10 billion per year. Commercial products range from those entirely composed of silicone to products where the silicone is a low level but key component. This symposium covered the recent academic and technological developments behind silicones and silicone-modified materials and the sessions were well attended of wide interest to both the academic and industrial communities. The papers from our two highly successful symposia in this important area were published in the books Silicones and Silicone-Modified Materials, (Eds. S. J. Clarson, J. J. Fitzgerald, M. J. Owen and S. D. Smith), ACS Symposium Series Vol. 729 / Oxford University Press, 2000, ISBN 0-8412-3613-5 and Synthesis and Properties of Silicones and Silicone-Modified Materials, (Eds. S. J.

The Shape of Thought: How Mental Adaptations Evolve presents a road map for an evolutionary psychology of the twenty-first century. It brings together theory from biology and cognitive science to show how the brain can be composed of specialized adaptations, and yet also an organ of plasticity. Although mental adaptations have typically been seen as monolithic, hard-wired components frozen in the evolutionary past, The Shape of Thought presents a new view of mental adaptations as diverse and variable, with distinct functions and evolutionary histories that shape how they develop, what information they use, and what they do with that information. The book describes how advances in evolutionary developmental biology can be applied to the brain by focusing on the design of the developmental systems that build it. Crucially, developmental systems can be plastic, designed by the process of natural selection to build adaptive phenotypes using the rich information available in our social and physical environments. This approach bridges the long-standing divide between "nativist" approaches to development, based on innateness, and "empiricist" approaches, based on learning. It shows how a view of humans as a flexible, culturally-dependent species is compatible with a complexly specialized brain, and how the nature of our flexibility can be better understood by confronting the evolved design of the organ on which that flexibility depends.
Storrs McCall presents an original philosophical theory of the nature of the universe based on a striking new model of its space-time structure. He shows that this theory can illuminate a wide variety of hitherto unresolved philosophical problems. These include: the direction and flow of time; the nature of scientific laws; the interpretation of quantum mechanics; the definition of probability; counterfactual semantics; and the notions of identity, essential properties, deliberation, decision, and free will. A particular instance of the explanatory powers of the proposed space-time model is its account of quantum non-locality in the EPR and GHZ experiments. Professor McCall argues that the fact that the model explains and throws light on such a broad range of problems constitutes strong evidence that the universe is as the model portrays it.

From the winner of the 2022 Royal Society Science Book Prize, a thrilling and thought-provoking account of the rise and fall of humankind. For the first time in over ten millennia, the rate of human population growth is slowing down. The global population is forecast to begin declining in the second half of this century, and in 10,000 years’ time, our species will likely be extinct. In The Decline and Fall of the Human Empire, Henry Gee shows how we arrived at this crucial moment in our history, beginning his story deep in the palaeolithic past and charting our dramatic rise from one species of human among many – teetering on the edge of extinction for more than a hundred millennia – to the most dominant animal to ever live on Earth. But rapid climate change, a stagnating global economy, falling birth rates and an unexplainable decline in average human sperm count are combining to make our chances for longevity increasingly slim. There could be a way forward, but the launch window is narrow. Gee argues that unless Homo sapiens establishes successful colonies in space within the next two centuries, our species is likely to stay earthbound and will have vanished entirely within another 10,000 years, bringing the seven-million-year story of the human lineage to an end. Drawing on a dazzling array of the latest scientific research, Gee tells the extraordinary story of humanity with characteristic warmth and wit, and suggests how our exceptional species might avoid its tragic fate.
Quantum City explores the metaphorical relationships between quantum theory, urban design and the concept of the city, with a very serious aim: to radically change the way the urban realm is both experienced and designed.Using the terminology and themes of quantum theory and the 'new physics', the author draws the reader into an intriguing discussion of the principles, practices and operations of urbanism. This new language offers the missing interface between the different disciplines of the city, and promises to be a potent metaphor for the development of various theories for the 21st century city.Challenging traditional approaches to the theory of cities, this thought-provoking book will be enjoyed by both design professionals and anyone interested in the city, its history and culture.
The Oxford Handbook of the Economics of Networks represents the frontier of research into how and why networks form, how they influence behavior, how they help govern outcomes in an interactive world, and how they shape collective decision making, opinion formation, and diffusion dynamics. From a methodological perspective, the contributors to this volume devote attention to theory, field experiments, laboratory experiments, and econometrics. Theoretical work in network formation, games played on networks, repeated games, and the interaction between linking and behavior is synthesized. A number of chapters are devoted to studying social process mediated by networks. Topics here include opinion formation, diffusion of information and disease, and learning. There are also chapters devoted to financial contagion and systemic risk, motivated in part by the recent financial crises. Another section discusses communities, with applications including social trust, favor exchange, and social collateral; the importance of communities for migration patterns; and the role that networks and communities play in the labor market. A prominent role of networks, from an economic perspective, is that they mediate trade. Several chapters cover bilateral trade in networks, strategic intermediation, and the role of networks in international trade. Contributions discuss as well the role of networks for organizations. On the one hand, one chapter discusses the role of networks for the performance of organizations, while two other chapters discuss managing networks of consumers and pricing in the presence of network-based spillovers. Finally, the authors discuss the internet as a network with attention to the issue of net neutrality.

Polymeric materials have been and continue to be a focus of
research in the development of materials for energy conversion,
storage and delivery applications (fuel cells, batteries,
photovoltaics, capacitors, etc.). Significant growth in this field
started in the early 1990s and has continued to grow quite
substantially since that time. Polymeric materials now have a
prominent place in energy research.
This volume presents state-of-the-art empirical studies working in a paradigm that has become known as human behavioral ecology. The emergence of this approach in anthropology was marked by publication by Aldine in 1979 of an earlier collection of studies edited by Chagnon and Irons entitled Evolutionary Biology and Human Social Behavior: An Anthropological Perspective. During the two decades that have passed since then, this innovative approach has matured and expanded into new areas that are explored here. The book opens with an introductory chapter by Chagnon and Irons tracing the origins of human behavioral ecology and its subsequent development. Subsequent chapters, written by both younger scholars and established researchers, cover a wide range of societies and topics organ-ized into six sections. The first section includes two chapters that provide historical background on the development of human behavioral ecology and com-pare it to two complementary approaches in the study of evolution and human behavior, evolutionary psychology, and dual inheritance theory. The second section includes five studies of mating efforts in a variety of societies from South America and Africa. The third section covers parenting, with five studies on soci-eties from Africa, Asia, and North America. The fourth section breaks somewhat with the tradition in human behavioral ecology by focusing on one particularly problematic issue, the demographic transition, using data from Europe, North America, and Asia. The fifth section includes studies of cooperation and helping behaviors, using data from societies in Micronesia and South America. The sixth and final section consists of a single chapter that places the volume in a broader critical and comparative context. The contributions to this volume demonstrate, with a high degree of theoretical and methodological sophistication--the maturity and freshness of this new paradigm in the study of human behavior. The volume will be of interest to anthropologists and other professions working on the study of cross-cultural human behavior.
This book contains a selection of refereed papers presented at the

Flora of North America, Volume 3, provides information on many of the most familiar wildflowers and trees in North America. Included are treatments of the buttercup family (Ranunculacaeae), with such plants as delphiniums and columbines, and the poppy family (Papveraceae). Most of the important broadleaf tree species are covered, including the oaks (Fagaceae), elms (Ulmaceae), birches (Betulaceae), walnuts (Juglandaceae), plane trees (Plantanaceae), and magnolias (Magnoliaceae). Many striking families are covered, such as the dutchman's pipe family (Aristochiaceae), and the aquatic families Nymphaeceae (water lilies), and Melumbonaceae (lotus). Identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, phenological information, and other significant biological observations are given for each species. The treatments, written and reviewed by experts throughout the systematic botanical community, are based on original observations of herbarium specimens, and wherever possible, on living plants. These observations are supplemented by critical reviews of the literature.
Developing innovative efficient and sensitive spectroscopic and optical techniques for studying biomedically relevant molecules, structures and processes in vitro and in vivo is a field of rapidly growing interest. This symposium book covers novel and exciting approaches in biomedical spectroscopy. Several chapters deal with infrared and Raman spectroscopy. These complimentary vibrational spectroscopic techniques are capable of monitoring molecular structures as well as structural changes. Such studies are of interest for understanding diseases at a molecular level as well as for developing techniques for efficient early diagnosis based on molecular structural information. The chapters demonstrate also applications vibrational spectroscopy in proteomics and the characterization of micro organisms. The second section of the book introduces surface enhanced Raman scattering (SERS), demonstrates the application of the effect in the biomedical field and develops the concept of multifunctional nanosensors. The measurement of intrinsic optical signals from biological objects such as nerve tissue are discussed in the next section of the book. Chapters deal also with Coherent anti-Stokes Raman scattering (CARS) and fluorescence fluctuation spectroscopy. Other chapters illustrate how photons of very different energies, in the Terahertz and in the ultra violet range, can be used to retrieve molecular structural information from native biomolecules. The electrical properties of protein molecules adsorbed onto a gold substrate are studied by using a scanning Kelvin nanoprobe in a microarray format. The final chapters in the book demonstrate the powerful combination of different spectroscopic techniques for the characterization of biomolecules as well as native and engineered biomaterials. These chapters combine information from Raman and Inelastic Neutron Scattering, optical absorbance and energy dispersive X-ray analysis, positron annihilation lifetime spectroscopy (PALS), 1H NMR, and 129Xe NMR X-ray diffraction and fluorescence resonance energy transfer.
Professors and research advisors have always endeavored to make the opportunity to gain new knowledge available to their students. However, new knowledge takes different forms. From a student perspective, it comes from reading textbooks and primary literature or attending classes and seminars. Professors share in these activities with their students, but they know that physically taking part in the acquisition of new knowledge through active research is where the true excitement begins. For many, if not all, faculty members research is the source of passion for chemistry, and sharing it with a rising generation of chemists often comprises a substantial part of the decision to pursue a career in the field of undergraduate education. These chapters and additional ones provide starting points for developing such a culture at the department level. In several cases the starting point is redesigning introductory or research methods courses to place a stronger emphasis on authentic research and its associated skills. In other cases the establishment of a thriving research group by one faculty member is the catalyst for initiating the departmental transformation. There are also several examples of how to set up an undergraduate research group in departments that place a heavy emphasis on research, and those that place less emphasis on research. Many of these offer roadmaps for developing interdisciplinary research groups or translating resource-intensive graduate-level research to an environment that is resource-restrictive. In still other cases the research has an experiential learning component. For many of the above examples the departmental/institutional role is not always obvious and may not be influential or important. This is a reminder that undergraduate research need not be "institutional" to be successful.
