Book Synopsis Analyzing Collapse by : Miroslav Bárta
Download or read book Analyzing Collapse written by Miroslav Bárta and published by American University in Cairo Press. This book was released on 2019-08-27 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the long-term trends in the development of what was the first complex civilization in history, the Old Kingdom of Egypt (c. 2650–2200 BC), the period that saw the construction of eternal monuments such as Djoser’s Step Pyramid complex in Saqqara, the pyramids of the great Fourth Dynasty kings in Giza, and spectacular tombs of high officials throughout Egypt. The present study aims to show that the historical trajectory of the period was marked by specific processes that characterize most of the world’s civilizations: the role of the ruling elite, the growth of bureaucracy, the proliferation of interest groups, and adaptation to climate change, to name but a few—and the way that these processes held the germ of ultimate collapse. The case is made that the rise and fall of the Old Kingdom state is of relevance to the study of the anatomy of development of any complex civilization.

Book excerpt: American scholar Jared Diamond deploys his powers of interpretation to great effect in Collapse: How Societies Choose to Fail or Succeed, which seeks to understand the meaning behind the available evidence describing societies that have survived and those that have withered and died. Why, for example, did the Norsemen of Scandinavia who colonized Greenland in the early tenth century not survive, while the inhabitants of Highland New Guinea did? With the evidence to hand, Diamond notes that a society’s collapse tends to be preceded by a severe reduction in population and considerable decreases in political, economic and social complexity. Delving even deeper, Diamond isolates five major factors determine the success or failure of human societies in all periods of history: environmental degradation, which occurs when an ecosystem deteriorates as its resources are exhausted; climate change (natural or man-made); hostile neighbors; weakened trading partners; and access or otherwise to the resources that enable the society to adapt its challenges. The breadth of Diamond’s research provides the springboard from which to reach these definitions, but it inevitably also introduces complications; how can evidence produced by specialists in so many different disciplines be compared? Diamond’s ability to understand the meaning of the evidence at hand – and his readiness to seek and supply clarifications of meaning where necessary – underpin his achievement, and comprise a textbook example of how interpretative skills can provide a framework for strong critical thinking.
Book Synopsis How Worlds Collapse by : Miguel Centeno
Download or read book How Worlds Collapse written by Miguel Centeno and published by Taylor & Francis. This book was released on 2023-03-30 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: As our society confronts the impacts of globalization and global systemic risks—such as financial contagion, climate change, and epidemics—what can studies of the past tell us about our present and future? How Worlds Collapse offers case studies of societies that either collapsed or overcame cataclysmic adversity. The authors in this volume find commonalities between past civilizations and our current society, tracing patterns, strategies, and early warning signs that can inform decision-making today. While today’s world presents unique challenges, many mechanisms, dynamics, and fundamental challenges to the foundations of civilization have been consistent throughout history—highlighting essential lessons for the future.
Book Synopsis Why Did the Soviet Union Collapse?: Understanding Historical Change by : Robert Strayer
Download or read book Why Did the Soviet Union Collapse?: Understanding Historical Change written by Robert Strayer and published by Routledge. This book was released on 2016-06-16 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking the Soviet collapse - the most cataclysmic event of the recent past - as a case study, this text engages students in the exercise of historical analysis, interpretation and explanation. In exploring the question posed by the title, the author introduces and applies such organizing concepts as great power conflict, imperial decline, revolution, ethnic conflict, colonialism, economic development, totalitarian ideology, and transition to democracy in a most accessible way. Questions and controversies, and extracts from documentary and literary sources, anchor the text at key points. This book is intended for use in history and political science courses on the Soviet Union or more generally on the 20th century.
Book Synopsis Bankrupt Representation and Party System Collapse by : Jana Morgan
Download or read book Bankrupt Representation and Party System Collapse written by Jana Morgan and published by Penn State Press. This book was released on 2011-11-23 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, Bolivia, Colombia, Italy, and Venezuela have all faced the turmoil and democratic crisis of party system collapse. In Bankrupt Representation and Party System Collapse, Jana Morgan analyzes the causes of such collapse. She does so through a detailed examination of Venezuela’s traumatic party system decay as well as comparative analysis of seven other countries. Collapse occurs when the party system as a whole is unable to provide adequate linkage between society and the state, failing to furnish programmatic representation, integration of major societal interests, or clientelist exchanges. Linkage decays when party systems face challenges that jeopardize their core strategies at the same time that they are constrained in their ability to adapt and to confront these threats. If this decay is unchecked and linkage of all sorts fails, then the bankrupt party system collapses.

Book Synopsis Collapse analysis of externally prestressed structures by : Jens Tandler
Download or read book Collapse analysis of externally prestressed structures written by Jens Tandler and published by diplom.de. This book was released on 2014-04-11 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: This dissertation is an investigation into the behaviour of externally prestressed structures, focusing on bridge box girders, at the ultimate limit state. The main objective is the ductility and the tendon stress increase up to failure of externally prestressed structures. Their behaviour will be compared to internally prestressed structures. The dissertation may have valuable information for the first stages of the design process for medium span bridges as the study is concerned about the overall safety and efficiency of prestressed concrete bridges by the means of ductility. The aim is also to provide information about the tendon stress at failure, which is required for the detailed design.

Download or read book The Collapse written by Mary Sarotte and published by Basic Books (AZ). This book was released on 2014-10-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the night of November 9, 1989, massive crowds surged toward the Berlin Wall, drawn by an announcement that caught the world by surprise: East Germans could now move freely to the West. The Wall—infamous symbol of divided Cold War Europe—seemed to be falling. But the opening of the gates that night was not planned by the East German ruling regime—nor was it the result of a bargain between either Ronald Reagan or George H.W. Bush and Soviet leader Mikhail Gorbachev. It was an accident. In The Collapse, prize-winning historian Mary Elise Sarotte reveals how a perfect storm of decisions made by daring underground revolutionaries, disgruntled Stasi officers, and dictatorial party bosses sparked an unexpected series of events culminating in the chaotic fall of the Wall. With a novelist’s eye for character and detail, she brings to vivid life a story that sweeps across Budapest, Prague, Dresden, and Leipzig and up to the armed checkpoints in Berlin. We meet the revolutionaries Roland Jahn, Aram Radomski, and Siggi Schefke, risking it all to smuggle the truth across the Iron Curtain; the hapless Politburo member Günter Schabowski, mistakenly suggesting that the Wall is open to a press conference full of foreign journalists, including NBC’s Tom Brokaw; and Stasi officer Harald Jäger, holding the fort at the crucial border crossing that night. Soon, Brokaw starts broadcasting live from Berlin’s Brandenburg Gate, where the crowds are exulting in the euphoria of newfound freedom—and the dictators are plotting to restore control. Drawing on new archival sources and dozens of interviews, The Collapse offers the definitive account of the night that brought down the Berlin Wall.

Download or read book Collapse written by Jared Diamond and published by Penguin UK. This book was released on 2013-03-21 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the author of Guns, Germs and Steel, Jared Diamond's Collapse: How Societies Choose to Fail or Survive is a visionary study of the mysterious downfall of past civilizations. Now in a revised edition with a new afterword, Jared Diamond's Collapse uncovers the secret behind why some societies flourish, while others founder - and what this means for our future. What happened to the people who made the forlorn long-abandoned statues of Easter Island? What happened to the architects of the crumbling Maya pyramids? Will we go the same way, our skyscrapers one day standing derelict and overgrown like the temples at Angkor Wat? Bringing together new evidence from a startling range of sources and piecing together the myriad influences, from climate to culture, that make societies self-destruct, Jared Diamond's Collapse also shows how - unlike our ancestors - we can benefit from our knowledge of the past and learn to be survivors. 'A grand sweep from a master storyteller of the human race' - Daily Mail 'Riveting, superb, terrifying' - Observer 'Gripping ... the book fulfils its huge ambition, and Diamond is the only man who could have written it' - Economis 'This book shines like all Diamond's work' - Sunday Times

Download or read book 1177 B.C. written by Eric H. Cline and published by Princeton University Press. This book was released on 2015-09-22 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bold reassessment of what caused the Late Bronze Age collapse In 1177 B.C., marauding groups known only as the "Sea Peoples" invaded Egypt. The pharaoh's army and navy managed to defeat them, but the victory so weakened Egypt that it soon slid into decline, as did most of the surrounding civilizations. After centuries of brilliance, the civilized world of the Bronze Age came to an abrupt and cataclysmic end. Kingdoms fell like dominoes over the course of just a few decades. No more Minoans or Mycenaeans. No more Trojans, Hittites, or Babylonians. The thriving economy and cultures of the late second millennium B.C., which had stretched from Greece to Egypt and Mesopotamia, suddenly ceased to exist, along with writing systems, technology, and monumental architecture. But the Sea Peoples alone could not have caused such widespread breakdown. How did it happen? In this major new account of the causes of this "First Dark Ages," Eric Cline tells the gripping story of how the end was brought about by multiple interconnected failures, ranging from invasion and revolt to earthquakes, drought, and the cutting of international trade routes. Bringing to life the vibrant multicultural world of these great civilizations, he draws a sweeping panorama of the empires and globalized peoples of the Late Bronze Age and shows that it was their very interdependence that hastened their dramatic collapse and ushered in a dark age that lasted centuries. A compelling combination of narrative and the latest scholarship, 1177 B.C. sheds new light on the complex ties that gave rise to, and ultimately destroyed, the flourishing civilizations of the Late Bronze Age—and that set the stage for the emergence of classical Greece.
Book Synopsis The Collapse Frequency of Structures by : Dirk Proske
Download or read book The Collapse Frequency of Structures written by Dirk Proske and published by Springer Nature. This book was released on 2022-05-12 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mathematical verification of the safety of structures can be done by determining the probability of failure or by using safety elements. Observed damages and collapses are usually assessed within the framework of expert reports, which seems reasonable due to the large number of unique structures in the construction industry. However, there should also be an examination of observed safety across all structures. Therefore, in this book the collapse frequencies are determined for different types of structures, such as bridges, dams, tunnels, retaining structures and buildings. The collapse frequency, like the failure probability, belongs to stochasticity. Therefore, the observed mean collapse frequencies and the calculated mean failure probabilities are compared. This comparison shows that the collapse frequencies are usually lower than the calculated failure probabilities. In addition, core damage frequencies and probabilities are given to extend the comparison to another technical product.
