The Abundant University: Remaking Higher Education for a Digital World
by Michael D. SmithWhy our current system of higher education is financially and morally unsustainable and how to address the crisis with the creative implementation of digital technologies.For too long, our system of higher education has been defined by scarcity: scarcity in enrollment, scarcity in instruction, and scarcity in credentials. In addition to failing students professionally, this system has exacerbated social injustice and socioeconomic stratification across the globe. In The Abundant University, Michael D. Smith argues that the only way to create a financially and morally sustainable higher education system is by embracing digital technologies for enrolling, instructing, and credentialing students—the same technologies that we have seen create abundance in access to resources in industry after industry.The Abundant University explains how we got our current system, why it&’s such an expensive, inefficient mess, and how a system based on exclusivity cannot foster inclusivity. Smith challenges the resistance to digital technologies that we have already seen among numerous institutions, citing the examples of faculty resistance toward digital learning platforms. While acknowledging the understandable self-preservation instinct of our current system of residential education, Smith makes a case for how technology can engender greater educational opportunity and create changes that will benefit students, employers, and society as a whole.

The Accidental Connoisseur: An Irreverent Journey Through the Wine World
by Lawrence Osborne“Witty, sometimes withering, learned and often loopy musings on the world of fine wine . . . an excellent drinking companion.” —Adam Sachs, NewsdayWhat is taste? Is it individual or imposed on us from the outside? Why are so many of us so intimidated when presented with the wine list at a restaurant? In The Accidental Connoisseur, journalist Lawrence Osborne takes off on a personal voyage through a little-known world in pursuit of some answers. Weaving together a fantastic cast of eccentrics and obsessives, industry magnates and small farmers, the author explores the way technological change, opinionated critics, consumer trends, wheelers and dealers, trade wars, and mass market tastes have made the elixir we drink today entirely different from the wine drunk by our grandparents.In his search for wine that is a true expression of the place that produced it, Osborne takes the reader from the high-tech present to the primitive past. From a lavish lunch with wine tsar Robert Mondavi to the cellars of Marquis Piero Antinori in Florence, from the tasting rooms of Chateau Lafite to the humble vineyards of northern Lazio, Osborne winds his way through Renaissance palaces, $27 million wineries, tin shacks and garages, opulent restaurants, world-famous chais and vineyards, renowned villages and obscure landscapes, as well as the great cities which are the temples of wine consumption: New York, San Francisco, Paris, Florence, and Rome. On the way, we will be shown the vast tapestry of this much-desired, little-understood drink: who produces it and why, who consumes it, who critiques it? Enchanting, delightful, entertaining, and, above all, down to earth, this is a wine book like no other.
The Accidental Seed Heroes: Growing a Delicious Food Future for All of Us
by Adam Alexander"A special, important book of hope, action and integrity."—Mark Diacono, food and garden writer"After reading Adam&’s book, I won&’t look at a handful of seed the same way again!"—Joe Swift, garden designer; writer; presenter, BBC&’s Gardeners&’ WorldAcross the world, chefs, farmers, plant scientists and backyard growers are doing something extraordinary: creating new generations of fruit, vegetables and cereals, all bred specifically to flourish locally, taste delicious, and contribute to our food future.In The Accidental Seed Heroes, Adam Alexander dons his seed detective homburg to meet these twenty-first century seed heroes, who are not only championing traditional varieties but also breeding delicious new ones that will help create a sustainable future for our planet.We don&’t all need to become backyard breeders or even, like Adam, accidental ones.

Adam just wants that choice to be better informed and infinitely more diverse and enjoyable.This story is a celebration of the locally and sustainably grown produce, whether traditional or innovative, that is at the heart of all our food cultures and empowers our rural communities and farmers. Adam believes these new varieties of fruits, vegetables and even grains will not just offer us all nutritious and delicious food but also be part of the solution to combating climate change and returning fertility to our soils and biodiversity to our land.
The Acid Queen: The Psychedelic Life and Counterculture Rebellion of Rosemary Woodruff Leary
by Susannah Cahalan&“Shines a light on one of the twentieth century&’s most amazing untold life stories. ... An essential read—and an unforgettable trip.&” —Robert Kolker, author of Hidden Valley Road &“Cahalan details a piece of lost but fascinating history, the story of a woman who embodied an era of freedom, experimentation, and psychedelic adventure. Meticulously reported and beautifully crafted.&” —Susan OrleanThe untold story of the woman who played a critical role in bringing psychedelics into the mainstream—until her audacious exploits forced her into the shadows—from the #1 New York Times bestselling author of Brain on FireRosemary Woodruff Leary has been known only as the wife of Timothy Leary, the Harvard professor-turned-psychedelic high priest, whose jailbreak captivated the counterculture and whose life on the run with Rosemary inflamed the government. But Rosemary was more than a mere accessory. She was a beatnik, a psychonaut, and a true believer who tested the limits of her mind and the expectations for women of her time.Long overlooked by those who have venerated her husband, Rosemary spent her life on the forefront of the counterculture, working with Leary on his books and speeches, sewing his clothing, and shaping—for better and for worse—the media&’s narrative about LSD. Ultimately, Rosemary sacrificed everything for the safety of her fellow psychedelic pioneers and the preservation of her husband&’s legacy.Drawing from a wealth of interviews, diaries, archives, and unpublished sources, Susannah Cahalan writes the definitive portrait of Rosemary Woodruff Leary, reclaiming her narrative and her voice from those who dismissed her. Page-turning, revelatory, and utterly compelling, The Acid Queen shines an overdue spotlight on a pioneering psychedelic seeker.

The Active Image
by Sabine Ammon Remei Capdevila-WerningThe "active image" refers to the operative nature of images, thus capturing the vast array of "actions" that images perform. This volume features essays that present a new approach to image theory. It explores the many ways images become active in architecture and engineering design processes and how, in the age of computer-based modeling, images play an indispensable role. The contributors examine different types of images, be they pictures, sketches, renderings, maps, plans, and photographs; be they analog or digital, planar or three-dimensional, ephemeral, realistic or imaginary. Their essays investigate how images serve as means of representing, as tools for thinking and reasoning, as ways of imagining the inexistent, as means of communicating and conveying information and how images may also perform functions and have an agency in their own. The essays discuss the role of images from the perspective of philosophy, theory and history of architecture, history of science, media theory, cognitive sciences, design studies, and visual studies, offering a multidisciplinary approach to imagery and showing the various methodologies and interpretations in current research. In addition, they offer valuable insight to better understand how images operate and function in the arts and sciences in general.
The Adaptive Military: Armed Forces in a Turbulent World
by Peter Jordan Caroline LloydWhen the cold war ended, many hoped it signified enhanced prospects for a more stable world. However, despite favorable political developments, the post-cold war period has been marked by turbulence, uncertainty, and challenge. The actions of rogue states such as Iraq and North Korea have made nuclear proliferation more unpredictable. Violence in Somalia and Bosnia has cast doubt on the viability of international peacekeeping arrangements. Hopes for expanding democratization have been dimmed by assertions that the values of liberal democracy and human rights are incompatible with non-Western cultures. The Adaptive Military describes how military security policies and practices have adapted to these new times and explains why such changes are necessary.The central argument is that current conflicts have been shaped by long-term trends, which increased the number and complexity of threats that the developed world is supposed to meet, and correspondingly decreased the stock of social and political options available to meet them.Although the authors differ in their assessments about the current prospects for peace and ways to maintain security, the issues they address are as critical as they were at the end of the Cold War. Mobilizing resources and political support for remote and difficult enterprises will always remain contentious, but if we recognize the hazard of letting violence run unopposed throughout the world, then we bear some responsibility to consider how it might be checked. This volume is an exercise of that responsibility. It will be of great interest to experts in military studies and international relations.
The Adaptive Water Resource Management Handbook
by Claudia Pahl-Wostl Jaroslav Mysiak Caroline Sullivan John Bromley Hans Jørgen HenriksonThe complexity of current water resource management poses many challenges. Water managers need to solve a range of interrelated water dilemmas, such as balancing water quantity and quality, flooding, drought, maintaining biodiversity and ecological functions and services, in a context where human beliefs, actions and values play a central role. Furthermore, the growing uncertainties of global climate change and the long term implications of management actions make the problems even more difficult. This book explains the benefits, outcomes and lessons learned from adaptive water management (AWM). In essence AWM is a way of responding to uncertainty by designing policy measures which are provisional and incremental, subject to subsequent modification in response to environmental change and other variables. Included are illustrative case studies from seven river basins from across Europe, West Asia and Africa: the Elbe, Rhine, Guadiana, Tisza, Orange, Nile and Amudarya. These exemplify the key challenges of adaptive water management, especially when rivers cross national boundaries, creating additional problems of governance.
