Standing up to Climate Change: Creating Prospects for a Sustainable Future in Rural Iran
by Shahrooz Mohajeri Lena Horlemann Ali A. Besalatpour Wolf RaberIn Iran, climate change combined with low adaptation capacity has an unparalleled impact on eco-systems as well as human livelihoods. The Roodasht region, in the lower part of the Zayandeh Rud basin in Central Iran, is severely affected by water scarcity, desertification and land degradation. This book describes the effects this has on the environment and society, analyzes the degree of vulnerability and suggests possible ways to improve land and water management. This book provides comprehensive and interdisciplinary insights into the environmental and social situation in the region, as well as possible solutions to deal with the current challenges. Written by German and Iranian scientists, NGO staff and government officials and bridging the gap between research and practical implementation, the book not only enhances our understanding of climate change and desertification, but also raises public awareness and promotes knowledge transfer between disciplines.
Standpipe Systems for Fire Protection
by Kenneth E. IsmanThis important new manual goes beyond the published NFPA standards on installation of standpipe systems to include the rules in the International Building Code, municipal fire codes, the National Fire Code of Canada, and information on inspection, testing, and maintenance of standpipe systems. Also covered are the interactions between standpipe and sprinkler systems, since these important fire protection systems are so frequently installed together. Illustrated with design examples and practical applications to reinforce the learning experience, this is the go-to reference for engineers, architects, design technicians, building inspectors, fire inspectors, and anyone that inspects, tests or maintains fire protection systems. Fire marshals and plan review authorities that have the responsibility for reviewing and accepting plans and hydraulic calculations for standpipe systems are also an important audience, as are firefighters who actually use standpipe systems. As a member of the committees responsible for some of these documents, Isman also covers the rules of these standards and codes as they are written, but also provides valuable insight as to the intent behind the rules. A noted author and lecturer, Professor Isman was an engineer with the National Fire Sprinkler Association (NFSA), is an elected Fellow of the Society of Fire Protection Engineers (SFPE), and currently Clinical Professor in the Department of Fire Protection Engineering at University of Maryland.

Stapleton's Real Estate Management Practice
by Anthony BanfieldPreviously known as Estate Management Practice, the fourth edition of this work has been renamed to reflect current market practice and to embrace the discipline of corporate real estate. This book provides a comprehensive study of the management of urban property and is divided into three parts. Part one considers the diverse nature of the many types of estates and different aspects and interpretations of the management task. Part two concentrates on the management of leased property, repairs, service charges and rent reviews and the statutory framework within which the landlord and tenant relationship has developed. Part three is concerned with the positive management covering both technical skills, such as portfolio performance, and the professional practice environment in which they are exercised. Stapleton’s Real Estate Management Practice is written both for advanced students and practitioners. It provides a firm basis for management affecting the decision-making hierarchy from tenant to property, to portfolio, to proprietary unit. While retaining the format of previous editions, it has been updated to reflect the many changes in the law, practice, technology and the market place since the previous edition. In addition, this new edition highlights factors that influence the enhancement of different types of property and the various strategies involved in managing properties from both owners’ and occupiers’ point of view.
Star Ark
by Rachel ArmstrongAs space ventures have become more numerous, leading scientists and theorists have offered ways of building a living habitat in a hostile environment, taking an 'ecosystems' view of space colonization. The contributors to this volume take a radical multi-disciplinary view of the challenge of human space colonization through the ongoing project Persephone. This book fundamentally challenges prevalent ideas about sustainability and proposes a new approach to resource austerity and conservation and providing truly sustainable approaches that are life-promoting. Readers will learn the details of the plans for Persephone - a real project that is part of the company Icarus Interstellar's plans for the design and engineering of a living interior on a worldship to be constructed in Earth's orbit within 100 years. Although the timeframe itself is only an estimate, since it is contingent on many significant developments, including funding and technological advances, the industry consensus is that within 100 years we will see manned space exploration beyond our solar system. This notion is shared by organizations such as the Initiative for Interstellar Studies and the DARPA-funded 100-year starship project. This book specifically develops the principles for the construction of a living habitat within a worldship - a multi-generational starship that contains its own world that supports colonists as it travels across great distances between stars at a speed much slower than light. Far from being a sterile industrial setup, such as the ISS, or even being a bucolic suburbia as proposed by Gerard O'Neill in the 1970s, this worldship will provide the pre-conditions for sustaining life beyond Earth's environment, which may also lead to the evolution of non-terrestrial ecologies. Drawing on the principles of ecopoiesis and insights offered by the Biosphere 2 experiment that demonstrated what we have to learn about ecosystem construction, this book proposes first designing the soils of such a space. It should then be possible to set up the conditions that a first generation of colonists may experience in leaving our solar system to find new worlds to settle - perhaps in spreading life throughout the universe. Although the book takes a unique view of ecology and sustainability within the setting of a traveling starship it is equally concerned with the human experience on artificial worlds. Chapters come from a range of multi disciplinary thinkers who shed light on the brave new future ahead from different angles.
The Star as Icon: Celebrity in the Age of Mass Consumption
by Daniel HerwitzPrincess Diana, Jackie O, Grace Kelly—the star icon is the most talked about yet least understood persona. The object of adoration, fantasy, and cult obsession, the star icon is a celebrity, yet she is also something more: a dazzling figure at the center of a media pantomime that is at once voyeuristic and zealously guarded. With skill and humor, Daniel Herwitz pokes at the gears of the celebrity-making machine, recruiting a philosopher's interest in the media, an eye for society, and a love of popular culture to divine our yearning for these iconic figures and the role they play in our lives.Herwitz portrays the star icon as caught between transcendence and trauma. An effervescent being living on a distant, exalted planet, the star icon is also a melodramatic heroine desperate to escape her life and the ever-watchful eye of the media. The public buoys her up and then eagerly watches her fall, her collapse providing a satisfying conclusion to a story sensationally told—while leaving the public yearning for a rebirth.Herwitz locates this double life in the opposing tensions of film, television, religion, and consumer culture, offering fresh perspectives on these subjects while ingeniously mapping society's creation (and destruction) of these special aesthetic stars. Herwitz has a soft spot for popular culture yet remains deeply skeptical of public illusion. He worries that the media distances us from even minimal insight into those who are transfigured into star icons. It also blinds us to the shaping of our political present.

The Star Builders: Nuclear Fusion and the Race to Power the Planet
by Arthur TurrellIs it possible to build a star on earth? When asked what problem he hoped scientists will have solved by the end of the century, Professor Stephen Hawking replied 'I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.' But what is nuclear fusion, and could it really be the answer to the climate emergency? Fusion exists already in the stars that fill our universe with light, but can we harness that power here on earth? This is the question The Star Builders seeks to answer. In his compelling new book, Dr Arthur Turrell makes the case for cutting-edge new techniques in nuclear energy - innovations that would allow us to recreate the power of the stars on our own planet. Filled with the remarkable stories of the scientists and entrepreneurs who have dedicated their lives to a seemingly impossible dream, The Star Builders is an unmissable insight into the future of life - and space - on our planet.
Star Crossed: The Story of Astronaut Lisa Nowak
by Kimberly C. MooreThe astronaut crime that shocked the world Star Crossed transports readers to the moment the news broke that one of America’s heroes, an astronaut who had flown aboard the Space Shuttle Discovery& just months before, had been arrested for a very bizarre crime. Lisa Nowak had driven 900 miles from Houston to Orlando to intercept and confront her romantic rival in an airport parking lot—allegedly using diapers on the trip so she wouldn’t have to stop. Nowak had been dating astronaut William “Billy” Oefelein when she learned that Oefelein was seeing a new girlfriend—U.S. Air Force Captain Colleen Shipman. The “astronaut love triangle” scandal quickly made headlines. The world watched as Nowak was dismissed from NASA, pleaded guilty to a felony, and received an “other than honorable” military discharge.An award-winning investigative reporter who covered Nowak’s criminal case, Kimberly Moore offers behind-the-scenes insights into Nowak’s childhood, her rigorous training, and her mission to space. Moore ventures inside the mind of the detective who studied the actions Nowak took that fateful February night. She includes never-before-told details of Nowak’s psychiatric diagnosis, taking a serious look at how someone so accomplished could spiral into mental illness to the point of possible attempted murder.This book spotlights the often-overlooked psychological health of astronauts, exploring how they are cared for by NASA doctors and what changes have been made in recent years to support space travelers on long-term missions. Expertly told, Moore’s story is a riveting journey inside the high-pressure world of one of America’s most elite agencies and the life of one beleaguered astronaut.

Star Power: ITER and the International Quest for Fusion Energy
by Alain BécouletA concise and accessible explanation of the science and technology behind the domestication of nuclear fusion energy.Nuclear fusion research tells us that the Sun uses one gram of hydrogen to make as much energy as can be obtained by burning eight tons of petroleum. If nuclear fusion—the process that makes the stars shine—could be domesticated for commercial energy production, the world would gain an inexhaustible source of energy that neither depletes natural resources nor produces greenhouse gases. In Star Power, Alan Bécoulet offers a concise and accessible primer on fusion energy, explaining the science and technology of nuclear fusion and describing the massive international scientific effort to achieve commercially viable fusion energy. Bécoulet draws on his work as Head of Engineering at ITER (International Thermonuclear Experimental Reactor) to explain how scientists are trying to &“put the sun in a box.&” He surveys the history of nuclear power, beginning with post–World War II efforts to use atoms for peaceful purposes and describes how energy is derived from fusion, explaining that the essential principle of fusion is based on the capacity of nucleons (protons and neutrons) to assemble and form structures (atomic nuclei) in spite of electrical repulsion between protons, which all have a positive charge. He traces the evolution of fusion research and development, mapping the generation of electric current though fusion. The ITER project marks a giant step in the development of fusion energy, with the potential to demonstrate the feasibility of a nuclear fusion reactor. Star Power offers an introduction to what may be the future of energy production.

Star Worlds: Freedom Versus Control in Online Gameworlds
by William Sims BainbridgeStar Worlds explores the future-oriented universe of online virtual worlds connected with popular science fiction--specifically, with Star Wars and Star Trek--that have been inhabited for over a decade by computer gamers. The Star Wars and Star Trek franchises, both of which have shaped the dominant science fiction mythologies of the last half-century, offer profound conceptions of the tension between freedom and control in human economic, political, and social interactions. Bainbridge investigates the human and technological dynamics of four online virtual worlds based on these two very different traditions: the massive multiplayer online games Star Wars Galaxies; Star Wars: The Old Republic; Star Trek Online; and the Star Trek community in the non-game, user-created virtual environment, Second Life. The four "star worlds" explored in this book illustrate the dilemmas concerning the role of technology as liberator or oppressor in our post-industrial society, and represent computer simulations of future possibilities of human experience. Bainbridge considers the relationship between a real person and the role that person plays, the relationship of an individual to society, and the relationship of human beings to computing technology. In addition to collecting ethnographic and quantitative data about the social behavior of other players, he has immersed himself in each of these worlds, role-playing 14 avatars with different skills and goals to gain new insights into the variety of player experience from a personal perspective.
