Book Description
Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.

Book Description
A provocative rethinking of how humans and fire have evolved together over time—and our responsibility to reorient this relationship before it's too late. The Pyrocene tells the story of what happened when a fire-wielding species, humanity, met an especially fire-receptive time in Earth's history. Since terrestrial life first appeared, flames have flourished. Over the past two million years, however, one genus gained the ability to manipulate fire, swiftly remaking both itself and eventually the world. We developed small guts and big heads by cooking food; we climbed the food chain by cooking landscapes; and now we have become a geologic force by cooking the planet. Some fire uses have been direct: fire applied to convert living landscapes into hunting grounds, forage fields, farms, and pastures. Others have been indirect, through pyrotechnologies that expanded humanity's reach beyond flame's grasp. Still, preindustrial and Indigenous societies largely operated within broad ecological constraints that determined how, and when, living landscapes could be burned. These ancient relationships between humans and fire broke down when people began to burn fossil biomass—lithic landscapes—and humanity's firepower became unbounded. Fire-catalyzed climate change globalized the impacts into a new geologic epoch. The Pleistocene yielded to the Pyrocene. Around fires, across millennia, we have told stories that explained the world and negotiated our place within it. The Pyrocene continues that tradition, describing how we have remade the Earth and how we might recover our responsibilities as keepers of the planetary flame.

Book Description
The last two years have witnessed a continuation in the breakthrough shift toward pulse tube cryocoolers for long-life, high-reliability cryocooler applications. New this year are papers de scribing the development of very large pulse tube cryocoolers to provide up to 1500 watts of cooling for industrial applications such as cooling the superconducting magnets of Mag-lev trains, coolmg superconducting cables for the power mdustry, and liquefymg natural gas. Pulse tube coolers can be driven by several competing compressor technologies. One class of pulse tube coolers is referred to as "Stirling type" because they are based on the linear Oxford Stirling-cooler type compressor; these generally provide coolmg m the 30 to 100 K temperature range and operate ^t frequencies from 30 to 60 Hz. A second type of pulse tube cooler is the so-called "Gifford-McMahon type. " Pulse tube coolers of this type use a G-M type compressor and lower frequency operation (~1 Hz) to achieve temperatures in the 2 to 10 K temperature range. The third type of pulse tube cooler is driven by a thermoacoustic oscillator, a heat engine that functions well in remote environments where electricity is not readily available. All three types are described, and in total, nearly half of this proceedings covers new developments in the pulse tube arena. Complementing the work on low-temperature pulse tube and Gifford-McMahon cryocoolers is substantial continued progress on rare earth regenerator materials.

Book Description
A practical guide to philanthropy at all levels of giving that seeks to educate and inspire A majority of American households give to charity in some form or another--from local donations to food banks, religious organizations, or schools, to contributions to prevent disease or protect basic freedoms. Whether you're in a position to give $1 or $1 million, every giver needs to answer the same question: How do I channel my giving effectively to make the greatest difference? In Giving Done Right, Phil Buchanan, the president of the Center for Effective Philanthropy, arms donors with what it takes to do more good more quickly and to avoid predictable errors that lead too many astray. This crucial book will reveal the secrets and lessons learned from some of the biggest givers, from the work of software entrepreneur Tim Gill and his foundation to expand rights for LGBTQ people to the efforts of a midwestern entrepreneur whose faith told him he must do something about childhood slavery in Ghana. It busts commonly held myths and challenging the idea that "business thinking" holds the answer to effective philanthropy. And it offers the intellectual frameworks, data-driven insights, tools, and practical examples to allow readers to understand exactly what it takes to make a difference.

Book Description
"Drawing from both current historical interpretations and new interdisciplinary perspectives, this collection provides diverse approaches to understanding the multilayered exchanges that went into creating cartographic knowledge in and about the Americas. In the introduction, editor Martin Brückner provides a critical assessment of the concept of cartography and of the historiography of maps. The individual essays, then, range widely over space and place, from the imperial reach of Iberian and British cartography to indigenous conceptualizations, including "dirty," ephemeral maps and star charts, to demonstrate that pre-nineteenth-century American cartography was at once a multiform and multicultural affair. The essays also bring to light original archives and innovative methodologies for investigating spatial relations among peoples in the Western Hemisphere." --from the publisher.

Book Description
Proceedings from the ninth International Conference on Artificial Life; papers by scientists of many disciplines focusing on the principles of organization and applications of complex, life-like systems. Artificial Life is an interdisciplinary effort to investigate the fundamental properties of living systems through the simulation and synthesis of life-like processes. The young field brings a powerful set of tools to the study of how high-level behavior can arise in systems governed by simple rules of interaction. Some of the fundamental questions include: What are the principles of evolution, learning, and growth that can be understood well enough to simulate as an information process? Can robots be built faster and more cheaply by mimicking biology than by the product design process used for automobiles and airplanes? How can we unify theories from dynamical systems, game theory, evolution, computing, geophysics, and cognition? The field has contributed fundamentally to our understanding of life itself through computer models, and has led to novel solutions to complex real-world problems across high technology and human society. This elite biennial meeting has grown from a small workshop in Santa Fe to a major international conference. This ninth volume of the proceedings of the international A-life conference reflects the growing quality and impact of this interdisciplinary scientific community.

Book Description
In Erotic Islands, Lyndon K. Gill maps a long queer presence at a crossroads of the Caribbean. This transdisciplinary book foregrounds the queer histories of Carnival, calypso, and HIV/AIDS in the Republic of Trinidad and Tobago. At its heart is an extension of Audre Lorde's use of the erotic as theory and methodology. Gill turns to lesbian/gay artistry and activism to insist on eros as an intertwined political-sensual-spiritual lens through which to see self and society more clearly. This analysis juxtaposes revered musician Calypso Rose, renowned mas man Peter Minshall, and resilient HIV/AIDS organization Friends For Life. Erotic Islands traverses black studies, queer studies, and anthropology toward an emergent black queer diaspora studies.
