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
“An arresting and meticulously researched collection of poems” about the life of Phillis Wheatley, the first black woman to publish a book in America (Ms. Magazine). In 1773, a young African American woman named Phillis Wheatley published a book of poetry, Poems on various Subjects, Religious and Moral (1773). When Wheatley’s book appeared, her words would challenge Western prejudices about African and female intellectual capabilities. Her words would astound many and irritate others, but one thing was clear: This young woman was extraordinary. Based on fifteen years of archival research, The Age of Phillis, by award-winning writer Honorée Fanonne Jeffers, imagines the life and times of Wheatley: her childhood with her parents in the Gambia, West Africa, her life with her white American owners, her friendship with Obour Tanner, her marriage to the enigmatic John Peters, and her untimely death at the age of about thirty-three. Woven throughout are poems about Wheatley's “age”—the era that encompassed political, philosophical, and religious upheaval, as well as the transatlantic slave trade. For the first time in verse, Wheatley’s relationship to black people and their individual “mercies” is foregrounded, and here we see her as not simply a racial or literary symbol, but a human being who lived and loved while making her indelible mark on history.

Book Description
This volume results from a conference held at the University of Kansas in 1995. The papers it encapsulates cover frontier studies from the third to the seventh century. It takes in the Roman world from Spain to Syria and from Britain to Dacia, clarifying the boundary role of Late Antiquity.

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
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
This book aims at providing insights into the collagen superfamily and the remarkable diversity of collagen function within the extracellular matrix. Additionally, the mechanisms underlying collagen-related diseases such as dystrophic epidermolysis bullosa, osteogenesis imperfecta, as well as collagen-related myopathies and neurological disorders are discussed. Collagens are the most abundant extracellular matrix proteins in organisms. Their primary function is to provide structural support and strength to cells and to maintain biomechanical integrity of tissues. However, collagens can no longer be considered just as structural proteins. They can act as extracellular modulators of signaling events and serve critical regulatory roles in various cell functions during embryonic development and adult homeostasis. Furthermore, collagens are associated with a broad spectrum of heritability-related diseases known as “collagenopathies” that affect a multitude of organs and tissues including sensorial organs. The book is a useful introduction to the field for junior scientists, interested in extracellular matrix research. It is also an interesting read for advanced scientists and clinicians working on collagens and collagenopathies, giving them a broader view of the field beyond their area of specialization.

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.
