Nanoweapons: A Growing Threat to Humanity

by Louis A. Del Monte

Nanoweapons just might render humanity extinct in the near future—a notion that is frightening and shocking but potentially true. In Nanoweapons Louis A. Del Monte describes the most deadly generation of military weapons the world has ever encountered. With dimensions one-thousandth the diameter of a single strand of human hair, this technology threatens to eradicate humanity as it incites world governments to compete in the deadliest arms race ever. In his insightful and prescient account of this risky and radical technology, Del Monte predicts that nanoweapons will dominate the battlefield of the future and will help determine the superpowers of the twenty-first century. He traces the emergence of nanotechnology, discusses the current development of nanoweapons—such as the “mini-nuke,” which weighs five pounds and carries the power of one hundred tons of TNT—and offers concrete recommendations, founded in historical precedent, for controlling their proliferation and avoiding human annihilation. Most critically, Nanoweapons addresses the question: Will it be possible to develop, deploy, and use nanoweapons in warfare without rendering humanity extinct?

Nantgarw and Swansea Porcelains: A Forensic Re-evaluation

by Howell G.M. Edwards

This book gives a detailed account of the holistic research carried out on the analytical data obtained historically on the products of the Nantgarw and Swansea porcelain manufactories which existed for a few years only during the second decade of the 19th Century. A background to the establishment of the two factories, which are linked through the persons of the enigmatic William Billingsley and his kiln manager, Samuel Walker, involves the sourcing of their raw materials and problems associated with the manufacture and distribution of the finished products. A description of the minerals and additives used in porcelain production is recounted to set the scene for the critical evaluation of the comprehensive analytical data which have been published on Nantgarw and Swansea porcelains. For the first time, the author has adopted a nondestructive technique, Raman spectroscopy, to interrogate perfect samples of Nantgarw and Swansea porcelain, as well as a selection of shards from an archaeological excavation carried out at a waste dump at the Nantgarw China Works site. Following these experiments, several questions relating to the porcelain bodies of Swansea and Nantgarw china can be answered and a protocol established for the preliminary evaluation of items of suspect attribution to confirm or not the correctness of their assignment to these Welsh porcelain factories.

Napalm: An American Biography

by Robert M. Neer

Napalm, incendiary gel that sticks to skin and burns to the bone, came into the world on Valentine's Day 1942 at a secret Harvard war research laboratory. On March 9, 1945, it created an inferno that killed over 87,500 people in Tokyo-more than died in the atomic explosions at Hiroshima or Nagasaki. It went on to incinerate sixty-four of Japan's largest cities. The Bomb got the press, but napalm did the work. After World War II, the incendiary held the line against communism in Greece and Korea-Napalm Day led the 1950 counter-attack from Inchon-and fought elsewhere under many flags. Americans generally applauded, until the Vietnam War. Today, napalm lives on as a pariah: a symbol of American cruelty and the misguided use of power, according to anti-war protesters in the 1960s and popular culture from Apocalypse Now to the punk band Napalm Death and British street artist Banksy. Its use by Serbia in 1994 and by the United States in Iraq in 2003 drew condemnation. United Nations delegates judged deployment against concentrations of civilians a war crime in 1980. After thirty-one years, America joined the global consensus, in 2011. Robert Neer has written the first history of napalm, from its inaugural test on the Harvard College soccer field, to a Marine Corps plan to attack Japan with millions of bats armed with tiny napalm time bombs, to the reflections of Phan Thi Kim Phuc, a girl who knew firsthand about its power and its morality.

Napoleon's Buttons

by Jay Burreson Penny Le Couteur

Napoleon's Buttons is the fascinating account of seventeen groups of molecules that have greatly influenced the course of history. These molecules provided the impetus for early exploration, and made possible the voyages of discovery that ensued. The molecules resulted in grand feats of engineering and spurred advances in medicine and law; they determined what we now eat, drink, and wear. A change as small as the position of an atom can lead to enormous alterations in the properties of a substance-which, in turn, can result in great historical shifts. With lively prose and an eye for colorful and unusual details, Le Couteur and Burreson offer a novel way to understand the shaping of civilization and the workings of our contemporary world.

Narrating Southern Chinese Minority Nationalities: Politics, Disciplines, and Public History (New Directions in East Asian History)

by Guo Wu

Based on fieldwork, archival research, and interviews, this book critically examines the building of modern Chinese discourse on a unified yet diverse Chinese nation on various sites of knowledge production. It argues that Chinese ideology on minority nationalities is rooted in modern China's quest for national integration and political authority. However, it also highlights the fact that the complex process of conceptualizing, investigating, classifying, curating, and writing minority history has been fraught with disputes and contradictions. As such, the book offers a timely contribution to the current debate in the fields of twentieth-century Chinese nationalism, minority policy, and anthropological practice.

Narrative Persuasion. A Cognitive Perspective on Language Evolution (Interdisciplinary Evolution Research #7)

by Francesco Ferretti

This book explores the evolutionary and cognitive foundations of human communication, focusing on narrative as its distinctive dimension. Within a framework of continuity with both the communication of our hominin predecessors and that of non-human animals, the book is about a twofold proposal. It includes the idea that (human and animal) communication has an intrinsically persuasive nature along with the hypothesis that humans developed narrative forms of communication in order to enhance their persuasive abilities. In this view, narrative persuasion becomes the feature that distinguishes human communication from animal communication. The study of the transition from animal communication to language addresses both the selective pressures that led communication for persuasive purposes to take a narrative form and the cognitive architectures and expressive systems that enabled our ancestors to cope with the selective pressures of persuasive/narrative-based communication. Language evolution is interdisciplinary, even from the specific perspective of evolutionary pragmatics chosen here. Therefore, this book is intended for researchers working in fields such as cognitive sciences, philosophy, evolutionary biology, cognitive psychology, and primatology. It also represents a valuable resource for advanced students in cognitive sciences, linguistics, and philosophy.

Narratives of Faith from the Haiti Earthquake: Religion, Natural Hazards and Disaster Response (Routledge Focus on Religion)

by Roger Philip Abbott Robert S. White

This book presents an in-depth ethnographic case study carried out in the years following the 2010 Haiti earthquake to present the role of faith beliefs in disaster response. The earthquake is one of the most destructive on record, and the aftermath, including a cholera epidemic and ongoing humanitarian aid, has continued for years following the catastrophe. Based on dozens of interviews, this book gives primacy to survivors’ narratives. It begins by laying out the Haitian context, before presenting an account of the earthquake from survivors’ perspectives. It then explores in detail how the earthquake affected the religious, mainly Christian, faith of survivors and how religious faith influenced how they responded to, and are recovering from, the experience. The account is also informed by geoscience and the accompanying "complicating factors." Finally, the Haitian experience highlights the significant role that religious faith can play alongside other learned coping strategies in disaster response and recovery globally. This book contributes an important case study to an emerging literature in which the influence of both religion and narrative is being recognised. It will be of interest to scholars of any discipline concerned with disaster response, including practical theology, anthropology, psychology, geography, Caribbean studies and earth science. It will also provide a resource for non-governmental organisations.

Narratives of Low-Carbon Transitions: Understanding Risks and Uncertainties (Routledge Studies in Energy Transitions)

by Jenny Lieu Susanne Hanger-Kopp Alexandros Nikas

"The Open Access version of this book, available at https://doi.org/10.4324/9780429458781, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives 4.0 license." This book examines the uncertainties underlying various strategies for a low-carbon future. Most prominently, such strategies relate to transitions in the energy sector, on both the supply and the demand side. At the same time they interact with other sectors, such as industrial production, transport, and building, and ultimately require new behaviour patterns at household and individual levels. Currently, much research is available on the effectiveness of these strategies but, in order to successfully implement comprehensive transition pathways, it is crucial not only to understand the benefits but also the risks. Filling this gap, this volume provides an interdisciplinary, conceptual framework to assess risks and uncertainties associated with low-carbon policies and applies this consistently across 11 country cases from around the world, illustrating alternative transition pathways in various contexts. The cases are presented as narratives, drawing on stakeholder-driven research efforts. They showcase diverse empirical evidence reflecting the complex challenges to and potential negative consequences of such pathways. Together, they enable the reader to draw valuable lessons on the risks and uncertainties associated with choosing the envisaged transition pathways, as well as ways to manage the implementation of these pathways and ultimately enable sustainable and lasting social and environmental effects. This book will be of great interest to students, scholars, and practitioners of environmental and energy policy, low-carbon transitions, renewable energy technologies, climate change action, and sustainability in general.
