R1,900 Discovery Miles 19 000 Ships in 10 - 15 working days

The only book of its kind to look at how our legal system needs to change to accommodate a world in which machines, in addition to people, make decisions. For years, robots were solely a matter of science fiction. Today, artificial intelligence technologies serve to accelerate our already fast-paced lives even further. From Apple's Siri to the Google Car to GPS, machines and technologies that make decisions and take action without direct human supervision have become commonplace in our daily lives. As a result, laws must be amended to protect companies that produce robots and the people that buy and use them. This book provides an extensive examination of how numerous legal areas-including liability, traffic, zoning, and international and constitutional law-must adapt to the widespread use of artificial intelligence in nearly every area of our society. The author scrutinizes the laws governing such fields as transportation, medicine, law enforcement, childcare, and real estate development. Describes court cases, regulations, and statutes that are affected by the technological advances of artificial intelligence Eschews overtly technical or legalistic discussions to provide clear, accessible information Discusses a number of popular, topical, and controversial technologies, providing historical background for each and their legal implications Focuses on devices that are already in use to illustrate where the law falls short in governing artificial intelligence and how legal models should be amended

El Capitan! The Making of an American Naval Officer (Hardcover): John Frank Gamboa El Capitan! The Making of an American Naval Officer (Hardcover)
John Frank Gamboa
R898 Discovery Miles 8 980 Ships in 10 - 15 working days

In 1958, Frank Gamboa became the first Mexican American from Owens Valley, California, to graduate from the United States Naval Academy. His memoir's focus is his professional development as a naval officer of the line from 1958 to 1988 in the U.S. Navy's surface warfare community. It highlights his duties, challenges and opportunities during more than 17 years of sea duty in destroyers, a cruiser, and six amphibious warships operating in the Navy's Second and Third Fleets; and in frequent and extended deployments in the Sixth and Seventh Fleets during the Cold War. El Capitan portrays the leadership, management, technical and seamanship skills required to succeed in shipboard billets ranging from division officer to commanding officer and squadron commander, in ranks from ensign to captain. It describes Gamboa's performance as the first Mexican-American naval surface warfare officer to command a major warship as a Commander, the first to command major warship as a Captain, and the first to command a squadron of amphibious warships as a captain. About the Author After leaving the Navy, Frank created Gamboa International Corporation, a management consulting company that he and Linda successfully operated in the private sector from 1994 to 2006. In 1989, he was elected Vice President of the Naval Academy Class of 1958 and continues to serve in that capacity. He and his wife, the former Linda Marie Lehtio, reside in Fairfax, Virginia. Their son, John Frank "Jack" Gamboa, Junior, and his daughter Emma live in Portland, Oregon. Their daughter Judith Ann Callsen and her husband Gary and her daughter Loren reside at Foxcroft School in Middleburg, Virginia.

R1,327 Discovery Miles 13 270 Ships in 12 - 17 working days

The fields of Economic Geography and International Business share an interest in the same phenomena, whilst each provides both a differing perspective and different research methods in attempting to understand those phenomena. The Routledge Companion to the Geography of International Business explores the nature and scope of inter-disciplinary work between Economic Geography and International Business in explaining the central issues in the international economy. Contributions written by leading specialists in each field (including some chapters written by inter-disciplinary teams) focus on the nature of multinational firms and their strategies, where they choose to locate their activities, how they create and manage international networks and the key relationships between multinationals and the places where they place their operations. Topics covered include the internationalisation of service industries, the influence of location on the competitiveness of firms and the economic dynamism of regions and where economic activity takes place and how knowledge, goods and services flow between locations. The book examines the areas for fruitful inter-disciplinary work between International Business and Economic Geography and sets out a road map for future joint research, and is an essential resource for students and practitioners of International Business and Economic Development.

The Quarantined Culture - Australian Reactions to Modernism, 1913-1939 (Paperback): John Frank Williams The Quarantined Culture - Australian Reactions to Modernism, 1913-1939 (Paperback)
John Frank Williams
R737 Discovery Miles 7 370 Ships in 12 - 17 working days

In 1913 the Australian press displayed a cosmopolitan openness to the culture of the modern world. By 1919, however, Australia had become an inward-looking society bent on keeping the outside world out - a quarantined culture. This book looks at the impact of the First World War on Australian culture, focussing on reactions to modernist art. John Williams argues that the creation of the Anzac legend, the back-to-the-land movement, notions of racial superiority and the mythology of the masculine nation were reactionary and anti-modern. Reflecting this, Australian pioneers of post-impressionism were ignored in favour of more traditional artists. This engaging book outlines the forces - social, economic, cultural, political - which led to the stagnation of Australian culture between the wars. John Williams' original and provocative work will make an important contribution to Australian cultural history.

Preventing and Managing Disabling Injury at Work (Paperback): Terrence Sullivan, John Frank Preventing and Managing Disabling Injury at Work (Paperback)
Terrence Sullivan, John Frank
R1,833 Discovery Miles 18 330 Ships in 12 - 17 working days

Work-related disability is an increasingly important issue to organizations, in terms of cost, competitiveness, and social and ethical issues. Changes in the nature of disability arising from the evolution of work calls for a new approach to this understudied topic. Significant developments have taken place in linking injury events with subsequent primary prevention efforts, in engaging key stakeholders in effective pre-injury prevention and post-injury disability management efforts, and in exploring company-level interventions, regulatory interventions, and economic incentives. These issues are examined and brought together to form a unique, evidence-based, state-of-the-art research work revealing what works best in preventing workplace disability. Preventing and Managing Disabling Injury at Work examines the changing nature of the workplace and work force, and includes the newest information on effective early and staged multi-modal interventions in the workplace. The text also explores psychological risk perception, and the essential linking of the workplace, clinician, insurer, and worker in the recovery process and in the prevention of subsequent disability events. This volume assembles a group of active researchers in the field of work-related disability from North America and Australia, many of whom manage interactive programs of work through HealNet, a health research network funded by Industry Canada. Well-illustrated with case studies and practical examples, much of the book focuses on the common musculoskeletal disabilities and 'regional disorders' along with other broader applications.

Reconstructing the University - Worldwide Shifts in Academia in the 20th Century (Paperback): David John Frank, Jay Gabler Reconstructing the University - Worldwide Shifts in Academia in the 20th Century (Paperback)
David John Frank, Jay Gabler; Foreword by John W. Meyer
R602 Discovery Miles 6 020 Ships in 12 - 17 working days

"Reconstructing the University is one of the most interesting books on changes in higher education that I have come across. By sampling university course catalogues from countries in Europe and the Americas to those in the Middle and Far East, Africa and Oceania, Frank and Gabler are able to map broad convergences in the fate of the humanities, social sciences and sciences over the course of the 20th century. The changes they demonstrate--especially, the phenomenal rise of the social sciences--suggest that it is more than plausible to think of universities as constituents of a worldwide republic of learning."--Gerhard Casper, President Emeritus, Stanford University
"The broad sweep of this study, both chronologically and geographically, is unprecedented in this area of research. The general pattern of findings--expanding social sciences, declining humanities, steady natural sciences throughout the world--and the specific findings for particular disciplines will be eye-opening for many specialists and professionals. This is a landmark study of the structure of organized knowledge."--John Boli, Emory University

The University and the Global Knowledge Society (Paperback): David John Frank, John W. Meyer The University and the Global Knowledge Society (Paperback)

R722 Discovery Miles 7 220 Ships in 12 - 17 working days

How the university went global and became the heart of the information age The university is experiencing an unprecedented level of success today, as more universities in more countries educate more students in more fields. At the same time, the university has become central to a knowledge society based on the belief that everyone can, through higher education, access universal truths and apply them in the name of progress. This book traces the university's rise over the past hundred years to become the cultural linchpin of contemporary society, revealing how the so-called ivory tower has become profoundly interlinked with almost every area of human endeavor. David John Frank and John Meyer describe how, as the university expanded, student and faculty bodies became larger, more diverse, and more empowered to turn knowledge into action. Their contributions to society underscored the public importance of scholarship, and as the cultural authority of universities grew they increased the scope of their research and teaching interests. As a result, the university has become the bedrock of today's information-based society, an institution that is now implicated in the solution to every conceivable problem. But, as Frank and Meyer also show, the conditions that helped spur the university's recent ascendance are not immutable: eruptions of nationalism, authoritarianism, and illiberalism undercut the university's universalistic and rationalistic premises, and may threaten the centrality of the university itself.

The theory of infinite loop spaces has been the center of much recent activity in algebraic topology. Frank Adams surveys this extensive work for researchers and students. Among the major topics covered are generalized cohomology theories and spectra; infinite-loop space machines in the sense of Boadman-Vogt, May, and Segal; localization and group completion; the transfer; the Adams conjecture and several proofs of it; and the recent theories of Adams and Priddy and of Madsen, Snaith, and Tornehave.
