In this monograph we study two generalizations of standard unification, E-unification and higher-order unification, using an abstract approach orig inated by Herbrand and developed in the case of standard first-order unifi cation by Martelli and Montanari. The formalism presents the unification computation as a set of non-deterministic transformation rules for con verting a set of equations to be unified into an explicit representation of a unifier (if such exists). This provides an abstract and mathematically elegant means of analysing the properties of unification in various settings by providing a clean separation of the logical issues from the specification of procedural information, and amounts to a set of 'inference rules' for unification, hence the title of this book. We derive the set of transformations for general E-unification and higher order unification from an analysis of the sense in which terms are 'the same' after application of a unifying substitution. In both cases, this results in a simple extension of the set of basic transformations given by Herbrand Martelli-Montanari for standard unification, and shows clearly the basic relationships of the fundamental operations necessary in each case, and thus the underlying structure of the most important classes of term unifi cation problems."

The detection and/or isolation and identification of pathogenic microorganisms is critical for the laboratory diagnosis of infectious diseases. With growth-dependant methods providing reliable means for identifying pathogens, traditional culturing continues to play an integral role in the detection and characterization of known and "new" microbial pathogens. Microbiologists, therefore, rely on a variety of media for the detection, isolation, characterization, and identification of primary and opportunistic microbial pathogens. The Handbook of Media for Clinical and Public Health Microbiology provides a compilation of the formulations, methods of preparation, and applications for media used in clinical and public health microbiology laboratories. It is a significant update to the Handbook of Media for Clinical Microbiology, expanding the coverage to media used for public health epidemiological investigations of disease outbreaks and including media used for the detection of pathogens in foods and environmental samples. Comprising both classic and modern media, the handbook describes almost 1,800 types of media, listed alphabetically, including new media for the cultivation of emerging bacteria, fungi, and viruses that are causing major medical problems around the world. Examples of emerging pathogens are extended-spectrum beta-lactamase (ESBL)-producing bacteria, Escherichia coli O157:H7, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and carbapenem-resistant Enterobacteriaceae (CRE). Many of the new media contain chromogenic or fluorogenic substrates that permit rapid detection of specific pathogens. The handbook's format allows easy reference to information needed to prepare media for cultivating clinically relevant microorganisms. It also contains descriptions of expected results for organisms that are important for the examination of foods, water, and other

People are increasingly aware of the role that water has in shaping society and how it impacts quality of life. This is the first book to provide a holistic perspective on water, capturing the full breadth of the science, technology, policy, history, and future outlook for the most important substance on earth - written at a level accessible to non-experts in each of these areas.Water is shockingly bizarre in its properties and of unsurpassed importance throughout human history, yet so mundane as to often be invisible in our daily lives. In Water Is ..., the two Seths (Darling and Snyder) walk the reader through all of the diverse perspectives on water. The journey begins with an exploration of the mysteries of water's properties on the molecular level, zooming out through its central role at biological and geological scales. Next, the Seths travel through the history of human civilization, highlighting the fundamental part water has played throughout, including the complexities of water policy, privatization, and pricing in today's world. Attention then turns to technology and innovation, emphasizing the daunting challenges dictated by increasing water stress and a changing climate as well as the enticing opportunities to achieve a secure global water future.Water is arguably the single most interdisciplinary topic. Students in business, policy, history, science, and engineering can best position themselves to make an impact by learning about the entire range of diverse, unexpected, and fascinating angles on water.Related Link(s)

Most great transformations are not apparent as we live through them. Only in hindsight do individual moments acquire layers of meaning that give them great significance. Looking back is not something that comes naturally to journalists, immersed as they are in breaking events and relentless deadlines. But there is still good reason for journalists, scholars, and people who care about journalism to think about the critical episodes in its recent evolution. In Defining Moments in Journalism, such authors vividly describe episodes of this kind. Some of the chapters and contributors include: "The Lessons of Little Rock" by Harry S. Ashmore; "Vietnam and War Reporting" by Peter Arnett; "Photo-journalists--Visionaries Who Have Changed Our Vision" by Jane M. Rosett; "The Weight of Watergate" by Ellen Hume; "Women Sportswriters--Business as Usual" by Mary Schmitt; "The Connie Chung Phenomenon" by Somini Sengupta; and "Covering Politics--Is There a Female Difference?" by Judy Woodruff. The years since the Great Depression and World War II have seen vast changes in America and also in its journalism. Journalists' relationship to power and authority is more complex; the press corps has become more diverse; the technology of news reporting is almost unrecognizably different from that of fifty years ago; and economic reorganization of the media has bundled news and entertainment organizations into conglomerates of extraordinary size. 'Defining Moments in Journalism' is a fascinating read for communications scholars and professionals, historians, and political scientists.

Threats to journalists carry many different lessons, but one is constant: People who would intimidate or kill journalists are usually terrified that someone might find out. Journalists who want to protect one another need do nothing more than what should come naturally to them: report on threats to journalists--big threats and small threats, whether they are directed against the international luminaries of the profession or small timers. Non-journalists can also play a big part in the fight to protect journalists. Next to tough and timely reporting that establishes the facts of a case, nothing protects a journalist so much as public outrage and public support. Ordinary citizens can play an enormous role by pressuring thugs and tyrants who would like to stifle the freedom of the press. The freedom of journalists is consequently the bedrock of freedom for all people. Chapters and contributors to 'Journalists in Peril' include: "The Clash of Arms in Exotic Locales" by Peter Arnett; "Press Freedom--Balkan Style" by Kati Marton; "Grim Prospects for Hong Kong" by John Schidlovsky; "Russian Reporters--Between a Hammer and an Anvil" by losif M. Dzyaloshinsky; "Defiant Publishing in Nigeria" by Dapo Olorunyomi; "Turkish Journalists on Trial" by Ahmet Emin; "In America, Justice for Some" by Ana Arana; and "Blood and Fear in Italy" by Candida Curzi. The tragic accounts detailed in 'Journalists in Peril' are poignantly written and are important reading for all concerned with democracy in the world, especially political scientists, government officials, and those involved in the various communications professions.

The future of journalism isn't what it used to be. As recently as the mid-1960s, few would have predicted the shocks and transformations that have swept through the news business in the last three decades: the deaths of many afternoon newspapers, the emergence of television as people's primary news source and the quicksilver combinations of cable television, VCRs and the Internet that have changed our ways of reading, seeing, and listening.The essays in this volume seek to illuminate the future prospects of journalism. Mindful that grandiose predictions of the world of tomorrow tend to be the fantasies and phobias of the present written large-in the 1930s and 1940s magazines such as Scribner's, Barron's, and Collier's forecast that one day we would have an airplane in every garage-the authors of What's Next? have taken a more careful view.The writers start with what they know-the trends that they see in journalism today-and ask where will they take us in the foreseeable future. For some media, such as newspapers, the visible horizon is decades away. For others, particularly anything involving the Internet, responsible forecasts can look ahead only for a matter of years. Where the likely destinations of present trends are not entirely clear, the authors have tried to pose the kinds of questions that they believe people will have to address in years to come.While being mindful of the tremendous influence of technology, one must remember that computers, punditry, or market share will not ordain the future of journalism. Rather, it will be determined by the sum of countless actions taken by journalists and other media professionals. These essays, with their hopes and fears, cautions and enthusiasms, questions and answers, are an effort to create the best possible future for journalism. This volume will be of interest to media professionals, academics and others with an interest in the future of journalism.

How much of myself (and my stuff) must I give up to follow Jesus? How does belonging to a faith community shape being a Christian? How do I walk in faith with friends whose faith is unclear or uncertain? What gives Christians hope in the face of power politics? Can I be pro-life and decry war, too? How do I make peace amidst the wrongs of the world? If you wonder about such questions, this book is for you. 'The Road That I Must Walk' represents the author's own wrestling with the call and cost of discipleship across a decade. Rather than an academic attempt to define or describe discipleship, these are simply the words of a disciple, one who has sought to walk in the way of Jesus. Arising from various circumstances and responding to various concerns, the several pieces collected here comprise a sketchbook of ethical reflections, biblical meditations, and spiritual ponderings drawn from one person's journey of following Jesus.

While evolving molecular diagnostic methods are being heralded for the role they will play in improving our ability to cultivate and identify bacteria, fungi, and viruses, the reality is that those new methods are still beyond the technical and financial reach of most clinical laboratories. Most clinical microbiology laboratories still rely upon culture methods for the identification of microorganisms of medical importance. The newest edition of the Handbook of Media for Clinical Microbiology addresses the needs of clinical microbiology laboratories and infectious disease researchers. Authored by Ronald Atlas and James Snyder, who over the years have built solid reputations among researchers for their exceptionally reliable media handbooks, this volume gives microbiologists in clinical and medical laboratories the reference they need to quickly and effectively deal with the modern challenges shaping the field. Organized for a fast-paced environment, this fully updated Second Edition provides clinical diagnostic laboratories with an easy-to-use reference for those routine and specialized media employed in the cultivation of pathogenic bacteria, fungi, and viruses. Almost 1,650 media are described in this edition, among them many newly developed media designed for the rapid detection and identification of disease-causing microorganisms, including those responsible for emerging and re-emerging infectious diseases. Describes media designed to cultivate and identify Escherichia coli O157:H7, methicillin-resistant Staphylococcus aureus, and vancomycin-resistant enterococci Includes chromogenic or fluorogenic substrates that permit the rapid detection of specific pathogens critical to the diagnosis of individuals with specific infectious diseases The Handbook provides a compilation of the formulations, methods of preparation, and applications for media used in the clinical microbiology laboratory.

In this monograph we study two generalizations of standard unification, E-unification and higher-order unification, using an abstract approach orig inated by Herbrand and developed in the case of standard first-order unifi cation by Martelli and Montanari. The formalism presents the unification computation as a set of non-deterministic transformation rules for con verting a set of equations to be unified into an explicit representation of a unifier (if such exists). This provides an abstract and mathematically elegant means of analysing the properties of unification in various settings by providing a clean separation of the logical issues from the specification of procedural information, and amounts to a set of 'inference rules' for unification, hence the title of this book. We derive the set of transformations for general E-unification and higher order unification from an analysis of the sense in which terms are 'the same' after application of a unifying substitution. In both cases, this results in a simple extension of the set of basic transformations given by Herbrand Martelli-Montanari for standard unification, and shows clearly the basic relationships of the fundamental operations necessary in each case, and thus the underlying structure of the most important classes of term unifi cation problems."

In the 1970s, when the South Bronx burned and the promise of New Deal New York and postwar America gave way to despair, the people of Washington Heights at the northern tip of Manhattan were increasingly vulnerable. The Heights had long been a neighborhood where generations of newcomers Irish, Jewish, Greek, African American, Cuban, and Puerto Rican carved out better lives in their adopted city. But as New York City shifted from an industrial base to a service economy, new immigrants from the Dominican Republic struggled to gain a foothold. Then the crack epidemic of the 1980s and the drug wars sent Washington Heights to the brink of an urban nightmare. But it did not go over the edge.

Robert W. Snyder's Crossing Broadway tells how disparate groups overcame their mutual suspicions to rehabilitate housing, build new schools, restore parks, and work with the police to bring safety to streets racked by crime and fear. It shows how a neighborhood once nicknamed "Frankfurt on the Hudson" for its large population of German Jews became Quisqueya Heights the home of the nation s largest Dominican community.

The story of Washington Heights illuminates New York City s long passage from the Great Depression and World War II through the urban crisis to the globalization and economic inequality of the twenty-first century. Washington Heights residents played crucial roles in saving their neighborhood, but its future as a home for working-class and middle-class people is by no means assured. The growing gap between rich and poor in contemporary New York puts new pressure on the Heights as more affluent newcomers move into buildings that once sustained generations of wage earners and the owners of small businesses.

Crossing Broadway is based on historical research, reporting, and oral histories. Its narrative is powered by the stories of real people whose lives illuminate what was won and lost in northern Manhattan s journey from the past to the present. A tribute to a great American neighborhood, this book shows how residents learned to cross Broadway over the decades a boundary that has separated black and white, Jews and Irish, Dominican-born and American-born and make common cause in pursuit of one of the most precious rights: the right to make a home and build a better life in New York City."

In this substantial new study Darrin Belousek presents a comprehensive and critical examination of standard Protestant atonement theology and offers an alternative to the theory of penal substitution that is both biblically grounded and theologically orthodox. Beginning with Paul?'s message of the cross and the Gospel narratives of Jesus, Belousek develops a comprehensive vision of justice and peace in light of the cross a vision that connects theology and ethics, salvation and mission. Integrating his biblical study and theological reflection with philosophical analysis, historical considerations, and social-scientific evidence, Belousek shows that Christian thinking on atonement is no mere academic exercise, but rather a practical theology that speaks to such concrete realities as economic justice, capital punishment, the war on terror, ethnic and religious conflict, and Christian disunity.

"Robert Snyder has compiled the tales and the war stories, sketches of the varied jobs and those who work on the buses and trains of the New York city mass transit system. These are the engrossing stories of the invisible workers-those who labor day and night to ensure a safe trip for the five million who ride the subways and buses of the city. Ever present, the workers have seen it all, and regale us with their experiences. It is an enjoyable read renewing our appreciation and respect for those who tend the transit systems."-New York History New York City may seem to be a place where everyone is a stranger, yet transit workers provide a human presence on a late-night bus or an empty subway platform. Few of us give any thought to these invisible workers-until something goes wrong. Transit Talk takes readers into the world of MTA New York City Transit employees, as they describe their lives and work, from the most visible subway conductor to the seemingly invisible mechanic. There are nearly 44,000 transit workers like those you will meet in Transit Talk, and every day they help five million of us travel to work, to school, to weddings, to funerals, to hospitals, to vacations. These workers labor daily on subway tracks inches from high-voltage powerlines, risking their lives for passengers they'll never know. The city can feel large and fragmented, but the transportation system and its workers create common threads in the lives of all New Yorkers, threads we take for granted. Nearly one hundred transit workers were interviewed for Transit Talk. These are the people who keep the country's largest transit system up and running. Together, their stories create a human tableau of life and labor in the city within a city that is the MTA New York City Transit. Transit workers find satisfaction in fixing a damaged subway car, gain wisdom from mastering a dangerous workplace, nurse emotional wounds from tending to someone injured in an accident, battle frustration from difficulties with management, and express satisfaction when reflecting on a productive career. They tell of how years spent in the same shop create bonds between workers. They talk of the burden of laboring in a twenty-four-hour system with night shifts and weekend workdays that take them away from families. You'll hear joyous anecdotes of workers delivering babies in a subway car as well as painful tales of informing next-of-kin of a death on the tracks. The stories weave together vignettes about race, unions, and the relations between men and women in the transit workforce. The memories recorded here cover the last fifty years of the twentieth century, a time when the transit system acquired many of the characteristics of contemporary modern American industry. Robert W. Snyder, a lifelong bus and subway rider and the grandson of a transit worker, is the author of The Voice of the City: Vaudeville and Popular Culture in New York and coauthor of Metropolitan Lives: The Ashcan Artists and Their New York. He lives with his wife and two children in Manhattan, where he is the editor of Media Studies Journal.

Biobased products offer substantial economic and environmental benefits, but understanding how to commercialize this requires a comprehensive look at the process, including feedstocks, technologies, product slate, supply chain, policy, financing, and environmental impact. Covering biobased products in a broad context, this book examines the environmental and economic impacts, compares US and EU policies, explores the factors affecting financing, and considers biological conversion, catalytic conversion, and separations. By examining the process from several critical perspectives in the supply chain, this book provides chemical engineers with a better understanding of challenges, opportunities, risks, and benefits of commercialization.

This entertaining and enlightening book depicts the rise of popular culture in America by brilliantly recapturing the essence and commercial trappings of one of its most vital forms of entertainment-the vaudeville show. Vaudeville was a meeting place, an inclusive form of theatre that flourished especially in New York, where it fostered cultural exchange among the city's ethnic groups. In The Voice of the City, Mr. Snyder reconstructs the famous acts, describes the different theatres, and shows how entrepreneurs created a near monopoly over bookings, theatres, and performers. He also gives us vaudeville's decline, its audiences usurped by musical comedy, radio, and the movies. "A fascinating and highly readable social history....By exploring the place of vaudeville in the neighborhoods and in the city central theatre district, Robert Snyder brilliantly illuminates the way city culture was made and worked in the lives of people at the turn of the century."-Thomas Bender. "The most authoritative book on American vaudeville...also a remarkably good read, filled with colorful details and incisive commentary on American popular culture in the decades surrounding the turn of the twentieth century."-David Nasaw.
