Book Description
The Earth has entered a new age—the Anthropocene—in which humans are the most powerful influence on global ecology. Since the mid-twentieth century, the accelerating pace of energy use, greenhouse gas emissions, and population growth has thrust the planet into a massive uncontrolled experiment. The Great Acceleration explains its causes and consequences, highlighting the role of energy systems, as well as trends in climate change, urbanization, and environmentalism. More than any other factor, human dependence on fossil fuels inaugurated the Anthropocene. Before 1700, people used little in the way of fossil fuels, but over the next two hundred years coal became the most important energy source. When oil entered the picture, coal and oil soon accounted for seventy-five percent of human energy use. This allowed far more economic activity and produced a higher standard of living than people had ever known—but it created far more ecological disruption. We are now living in the Anthropocene. The period from 1945 to the present represents the most anomalous period in the history of humanity’s relationship with the biosphere. Three-quarters of the carbon dioxide humans have contributed to the atmosphere has accumulated since World War II ended, and the number of people on Earth has nearly tripled. So far, humans have dramatically altered the planet’s biogeochemical systems without consciously managing them. If we try to control these systems through geoengineering, we will inaugurate another stage of the Anthropocene. Where it might lead, no one can say for sure.

Book Description
The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Description
This book provides a detailed general overview of the human factors and performance limitations associated with flying fast jets, integrating all the latest available research literature on the demanding operational tasks faced by such pilots and aircrews. As such, it has a strong military focus, dealing with pilots of fighter aircraft, attack aircraft and lead-in fighter trainer aircraft that are traditionally only single or dual pilot operations. The book deals not only with the issue of G force, but discusses ejection and escape/survival, disorientation, high altitude physiology, pilot training and selection, helmet-mounted equipment, situational awareness, data fusion and multi-sensor integration, human machine interface issues and advanced cockpit design. It examines the human performance issues associated with the technological advances made in fast jets, such as increased manoeuvrability, increased use of the pilot’s head as a mounting platform for sensor and weapons systems, and the complexities involved in the human-machine interface within these aircraft.

Book Description
Ergonomics is a human-centered discipline. This is particularly true for healthcare systems and patient safety where the human’s well-being will undergo critical impacts if solutions are not properly designed and practiced. Effective handling of these concerns involves knowledge from healthcare work (e.g., shift work, patient handling, and medical teamwork), to safety research (resilience, medical process control, intensive care, surgery/anesthesiology, and patient involvement), and to more general issues such as community participation in public affairs. To pursue the mission, the Healthcare System Ergonomics and Patient Safety (HEPS) commenced its first conference in Florence, Italy in 2005. Following the founding success, HEPS became an IEA-sponsored event and the series subsequently took place in Strasbourg, France in 2008, and in Oviedo, Spain in 2011. The three remarkable conferences have forged a world-class platform for researchers and practitioners from around the globe to exchange and disseminate the knowledge in HEPS. This volume contains the selected papers presented at the Fourth International conference on HEPS, held from June 23 to 26, 2014 in Taiwan. The Fourth HEPS, organized by the Ergonomics Society of Taiwan (EST) and endorsed by the International Ergonomics Association (IEA), aims to consolidate the knowledge bridged between ergonomics research and healthcare practices for the safety and welfare of patients. Researchers, professionals, and practitioners in ergonomics and healthcare around the world have shared their wisdom, experience, insights, and visions on past, current and future efforts in healthcare systems ergonomics and patient safety. The papers contributing to this book address the latest research, applications and practices in accordance with the theme of the conference, "Bridging Research and Good Practices towards Patients Welfare," and cover the following areas: "Aging and Healthcare System", "Healthcare, Mobil Application and Usability", "Safety, Hazards and MSDs", "Simulation, Modeling and Decision Making", "Environment and System Design", and "Human Factors and Product Design".
