Work is changing. Speed and flexibility are more in demand than ever before thanks to an accelerating knowledge economy and sophisticated communication networks. These changes have forced a mass rethinking of the way we coordinate, collaborate, and communicate. Instead of projects coming to established teams, teams are increasingly converging around projects. These "e;all-edge adhocracies"e; are highly collaborative and mostly temporary, their edge coming from the ability to form links both inside and outside an organization. These nimble groups come together around a specific task, recruiting personnel, assigning roles, and establishing objectives. When the work is done they disband their members and take their skills to the next project.Spinuzzi offers for the first time a comprehensive framework for understanding how these new groups function and thrive. His rigorous analysis tackles both the pros and cons of this evolving workflow and is based in case studies of real all-edge adhocracies at work. His provocative results will challenge our long-held assumptions about how we should be doing work.

Rudolf Raff is recognized as a pioneer in evolutionary developmental biology. In their 1983 book, Embryos, Genes, and Evolution, Raff and co-author Thomas Kaufman proposed a synthesis of developmental and evolutionary biology. In The Shape of Life, Raff analyzes the rise of this new experimental discipline and lays out new research questions, hypotheses, and approaches to guide its development.Raff uses the evolution of animal body plans to exemplify the interplay between developmental mechanisms and evolutionary patterns. Animal body plans emerged half a billion years ago. Evolution within these body plans during this span of time has resulted in the tremendous diversity of living animal forms.Raff argues for an integrated approach to the study of the intertwined roles of development and evolution involving phylogenetic, comparative, and functional biology. This new synthesis will interest not only scientists working in these areas, but also paleontologists, zoologists, morphologists, molecular biologists, and geneticists.

The right-to-die debate has gone on for centuries, playing out most recently as a spectacle of protest surrounding figures such as Terry Schiavo. In?Deconstructing Dignity, Scott Cutler Shershow offers a powerful new way of thinking about it philosophically. Focusing on the concepts of human dignity and the sanctity of life, he employs Derridean deconstruction to uncover self-contradictory and damaging assumptions that underlie both sides of the debate.Shershow examines texts from Cicero's?De Officiis?to Kant's?Groundwork of the Metaphysics of Morals?to court decisions and religious declarations. Through them he reveals how arguments both supporting and denying the right to die undermine their own unconditional concepts of human dignity and the sanctity of life with a hidden conditional logic, one often tied to practical economic concerns and the scarcity or unequal distribution of medical resources. He goes on to examine the exceptional case of self-sacrifice, closing with a vision of a society-one whose conditions we are far from meeting-in which the debate can finally be resolved. A sophisticated analysis of a heated topic,?Deconstructing Dignity?is also a masterful example of deconstructionist methods at work.?

Coevolution-reciprocal evolutionary change in interacting species driven by natural selection-is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes.Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.

Sandra Laugier has long been a key liaison between American and European philosophical thought, responsible for bringing American philosophers such as Ralph Waldo Emerson, Henry David Thoreau, and Stanley Cavell to French readers-but until now her books have never been published in English. Why We Need Ordinary Language Philosophy rights that wrong with a topic perfect for English-language readers: the idea of analytic philosophy.?Focused on clarity and logical argument, analytic philosophy has dominated the discipline in the United States, Australia, and Britain over the past one hundred years, and it is often seen as a unified, coherent, and inevitable advancement. Laugier questions this assumption, rethinking the very grounds that drove analytic philosophy to develop and uncovering its inherent tensions and confusions. Drawing on J. L. Austin and the later works of Ludwig Wittgenstein, she argues for the solution provided by ordinary language philosophy-a philosophy that trusts and utilizes the everyday use of language and the clarity of meaning it provides-and in doing so offers a major contribution to the philosophy of language and twentieth- and twenty-first-century philosophy as a whole.

The term "e;community organizer"e; was deployed repeatedly against Barack Obama during the 2008 presidential campaign as a way to paint him as an inexperienced politician unfit for the presidency. The implication was that the job of a community organizer wasn't a serious one, and that it certainly wasn't on the list of credentials needed for a presidential?resume.?In reality, community organizers have played key roles in the political lives of American cities for decades, perhaps never more so than during the 1970s in Chicago, where African Americans laid the groundwork for further empowerment as they organized against segregation, discrimination, and lack of equal access to schools, housing, and jobs.In?Crucibles of Black Empowerment, Jeffrey Helgeson recounts the rise of African American political power and activism from the 1930s onward, revealing how it was achieved through community building. His book tells stories of the housewives who organized their neighbors, building tradesmen who used connections with federal officials to create opportunities in a deeply discriminatory employment sector, and the social workers, personnel managers, and journalists who carved out positions in the white-collar workforce. ?Looking closely at black liberal politics at the neighborhood level in Chicago, Helgeson explains how black Chicagoans built the networks that eventually would overthrow the city's seemingly invincible political machine.

King Lear is perhaps the most fierce and moving play ever written. And yet there is a curious puzzle at its center. The figure to whom Shakespeare gives more lines than anyone except the king-Edgar-has often seemed little more than a blank, ignored and unloved, a belated moralizer who, try as he may, can never truly speak to the play's savaged heart. He saves his blinded father from suicide, but even this act of care is shadowed by suspicions of evasiveness and bad faith.In Poor Tom, Simon Palfrey asks us to go beyond any such received understandings-and thus to experience King Lear as never before. He argues that the part of Edgar is Shakespeare's most radical experiment in characterization, and his most exhaustive model of both human and theatrical possibility. The key to the Edgar character is that he spends most of the play disguised, much of it as "e;Poor Tom of Bedlam,"e; and his disguises come to uncanny life. The Edgar role is always more than one person; it animates multitudes, past and present and future, and gives life to states of being beyond the normal reach of the senses-undead, or not-yet, or ghostly, or possible rather than actual. And because the Edgar role both connects and retunes all of the figures and scenes in King Lear, close attention to this particular part can shine stunning new light on how the whole play works.The ultimate message of Palfrey's bravura analysis is the same for readers or actors or audiences as it is for the characters in the play: see and listen feelingly; pay attention, especially when it seems as though there is nothing there.

In the years since the Mars Exploration Rover Spirit and Opportunity first began transmitting images from the surface of Mars, we have become familiar with the harsh, rocky, rusty-red Martian landscape. But those images are much less straightforward than they may seem to a layperson: each one is the result of a complicated set of decisions and processes involving the large team behind the Rovers.With Seeing Like a Rover, Janet Vertesi takes us behind the scenes to reveal the work that goes into creating our knowledge of Mars. Every photograph that the Rovers take, she shows, must be processed, manipulated, and interpreted-and all that comes after team members negotiate with each other about what they should even be taking photographs of in the first place. Vertesi's account of the inspiringly successful Rover project reveals science in action, a world where digital processing uncovers scientific truths, where images are used to craft consensus, and where team members develop an uncanny intimacy with the sensory apparatus of a robot that is millions of miles away. Ultimately, Vertesi shows, every image taken by the Mars Rovers is not merely a picture of Mars-it's a portrait of the whole Rover team, as well.

In the digital age, photography confronts its future under the competing signs of ubiquity and obsolescence. While technology has allowed amateurs and experts alike to create high-quality photographs in the blink of an eye, new electronic formats have severed the original photochemical link between image and subject. At the same time, recent cinematic photography has stretched the concept of photography and raised questions about its truth value as a documentary medium. Despite this situation, photography remains a stubbornly substantive form of evidence: referenced by artists, filmmakers, and writers as a powerful emblem of truth, photography has found its home in other media at precisely the moment of its own material demise.By examining this idea of photography as articulated in literature, film, and the graphic novel, Daguerreotypes demonstrates how photography secures identity for figures with an otherwise unstable sense of self. Lisa Saltzman argues that in many modern works, the photograph asserts itself as a guarantor of identity, whether genuine or fabricated. From Roland Barthes's Camera Lucida to Ridley Scott's Blade Runner, W. G. Sebald's Austerlitz to Alison Bechdel's Fun Home-we find traces of photography's "e;fugitive subjects"e; throughout contemporary culture. Ultimately, Daguerreotypes reveals how the photograph, at once personal memento and material witness, has inspired a range of modern artistic and critical practices.

A heated debate is raging over our nation's public schools and how they should be reformed, with proposals ranging from imposing national standards to replacing public education?altogether with a voucher system for private schools. Combining decades of experience in education, the authors propose an innovative approach to solving the problems of our school system and find a middle ground between these extremes.Reinventing Public Education shows how contracting would radically change the way we operate our schools, while keeping them public and accessible to all, and making them better able to meet standards of achievement and equity. Using public funds, local school boards would select private providers to operate individual schools under formal contracts specifying the type and quality of instruction.In a hands-on, concrete fashion, the authors provide a thorough explanation of the pros and cons of school contracting and how it would work in practice. They show how contracting would free local school boards from operating schools so they can focus on improving educational policy; how it would allow parents to choose the best school for their children; and, finally, how it would ensure that schools are held accountable and academic standards are met.While retaining a strong public role in education, contracting enables schools to be more imaginative, adaptable, and suited to the needs of children and families. In presenting an alternative vision for America's schools, Reinventing Public Education is too important to be ignored.

How does globalization workFocusing on Latin America, Yves Dezalay and Bryant G. Garth show that exports of expertise and ideals from the United States to Argentina, Brazil, Chile, and Mexico have played a crucial role in transforming their state forms and economies since World War II.Based on more than 300 extensive interviews with major players in governments, foundations, law firms, universities, and think tanks, Dezalay and Garth examine both the production of northern exports such as neoliberal economics and international human rights law and the ways they are received south of the United States. They find that the content of what is exported and how it fares are profoundly shaped by domestic struggles for power and influence-"e;palace wars"e;-in the nations involved. For instance, challenges to the eastern intellectual establishment influenced the Reagan-era export of University of Chicago-style neoliberal economics to Chile, where it enjoyed a warm reception from Pinochet and his allies because they could use it to discredit the previous regime.Innovative and sophisticated, The Internationalization of Palace Wars offers much needed concrete information about the transnational processes that shape our world.

Ground-breaking when first published in 1945, Black Metropolis remains a landmark study of race and urban life. Few studies since have been able to match its scope and magnitude, offering one of the most comprehensive looks at black life in America. Based on research conducted by Works Progress Administration field workers, it is a sweeping historical and sociological account of the people of Chicago's South Side from the 1840s through the 1930s. Its findings offer a comprehensive analysis of black migration, settlement, community structure, and black-white race relations in the first half of the twentieth century. It offers a dizzying and dynamic world filled with captivating people and startling revelations.A new foreword from sociologist Mary Pattillo places the study in modern context, updating the story with the current state of black communities in Chicago and the larger United States and exploring what this means for the future. As the country continues to struggle with race and our treatment of black lives, Black Metropolis continues to be a powerful contribution to the conversation.

The relation between virtue and knowledge is at the heart of the Socratic view of human excellence, but it also points to a central puzzle of the Platonic dialogues: Can Socrates be serious in his claims that human excellence is constituted by one virtue, that vice is merely the result of ignorance, and that the correct response to crime is therefore not punishment but educationOr are these assertions mere rhetorical ploys by a notoriously complex thinker?Lorraine Smith Pangle traces the argument for the primacy of virtue and the power of knowledge throughout the five dialogues that feature them most prominently-the Apology, Gorgias, Protagoras, Meno, and Laws-and reveals the truth at the core of these seemingly strange claims. She argues that Socrates was more aware of the complex causes of human action and of the power of irrational passions than a cursory reading might suggest. Pangle's perceptive analyses reveal that many of Socrates's teachings in fact explore the factors that make it difficult for humans to be the rational creatures that he at first seems to claim. Also critical to Pangle's reading is her emphasis on the political dimensions of the dialogues. Underlying many of the paradoxes, she shows, is a distinction between philosophic and civic virtue that is critical to understanding them.Ultimately, Pangle offers a radically unconventional way of reading Socrates's views of human excellence: Virtue is not knowledge in any ordinary sense, but true virtue is nothing other than wisdom.

Frozen mammals of the Ice Age, preserved for millennia in the tundra, have been a source of fascination and mystery since their first discovery over two centuries ago. These mummies, their ecology, and their preservation are the subject of this compelling book by paleontologist Dale Guthrie. The 1979 find of a frozen, extinct steppe bison in an Alaskan gold mine allowed him to undertake the first scientific excavation of an Ice Age mummy in North America and to test theories about these enigmatic frozen fauna.The 36,000-year-old bison mummy, coated with blue mineral crystals, was dubbed "e;Blue Babe."e; Guthrie conveys the excitement of its excavation and shows how he made use of evidence from living animals, other Pleistocene mummies, Paleolithic art, and geological data. With photographs and scores?of detailed drawings, he takes the reader through the excavation and subsequent detective work, analyzing the animal's carcass and its surroundings, the circumstances of its death, its appearance in life, the landscape it inhabited, and the processes of preservation by freezing. His examination shows that Blue Babe died in early winter, falling prey to lions that inhabited the Arctic during the Pleistocene era.Guthrie uses information gleaned from his study of Blue Babe to provide a broad picture of bison evolutionary history and ecology, including speculations on the interactions of bison and Ice Age peoples. His de*ion of the Mammoth Steppe as a cold, dry, grassy plain is based on an entirely new way of reading the fossil record.
