Book Description
Applied topology is a modern subject which emerged in recent years at a crossroads of many methods, all of them topological in nature, which were used in a wide variety of applications in classical mathematics and beyond. Within applied topology, discrete Morse theory came into light as one of the main tools to understand cell complexes arising in different contexts, as well as to reduce the complexity of homology calculations. The present book provides a gentle introduction into this beautiful theory. Using a combinatorial approach—the author emphasizes acyclic matchings as the central object of study. The first two parts of the book can be used as a stand-alone introduction to homology, the last two parts delve into the core of discrete Morse theory. The presentation is broad, ranging from abstract topics, such as formulation of the entire theory using poset maps with small fibers, to heavily computational aspects, providing, for example, a specific algorithm of finding an explicit homology basis starting from an acyclic matching. The book will be appreciated by graduate students in applied topology, students and specialists in computer science and engineering, as well as research mathematicians interested in learning about the subject and applying it in context of their fields.

Book Description
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

Book Description
A user’s guide to economic, political, social and cultural collapse. In the face of political impotence, resource depletion, and catastrophic climate change, many of us have become reconciled to an uncertain future. However, popular perception of how this future might actually unfold varies wildly from "a severe and prolonged recession," to James Howard Kunstler's "long emergency," to the complete breakdown of civilization. In The Five Stages of Collapse , Dmitry Orlov posits a taxonomy of collapse, offering a surprisingly optimistic perspective on surviving the sweeping changes of the day with health and sanity intact. Arguing that it is during periods of disruption and extreme uncertainty that broad cultural change becomes possible, Orlov steers the reader through the challenges of financial, commercial, and political collapse. He suggests that if the first three stages are met with the appropriate responses, further breakdown may be arrested before the extremes of social and cultural collapse are reached. Drawing on a detailed examination of post-collapse societies, including the Somali people of Africa, the Pashtuns of Afghanistan, the Roma of Central and Eastern Europe, and even the Russian mafia, The Five Stages of Collapse describes successful adaptations in areas such as finance, self-governance, and social and cultural organization. These fascinating case studies provide a unique perspective on the characteristics that determine highly resilient communities. Shot through with Orlov's trademark dark humor, this is an invaluable toolkit for creating workable post-collapse solutions. Dmitry Orlov was born in Leningrad, Russia, and immigrated to the United States. He is the author of Reinventing Collapse and maintains the phenomenally popular blog Club Orlov.

Book Description
The book that inspired the movie Collapse. The world is running short of energy-especially cheap, easy-to-find oil. Shortages, along with resulting price increases, threaten industrialized civilization, the global economy, and our entire way of life. In Confronting Collapse, author Michael C. Ruppert, a former LAPD narcotics officer turned investigative journalist, details the intricate connections between money and energy, including the ways in which oil shortages and price spikes triggered the economic crash that began in September 2008. Given the 96 percent correlation between economic growth and greenhouse gas emissions and the unlikelihood of economic growth without a spike in energy use, Ruppert argues that we are not, in fact, on the verge of economic recovery, but on the verge of complete collapse. Ruppert's truth is not merely inconvenient. It is utterly devastating. But there is still hope. Ruppert outlines a 25-point plan of action, including the creation of a second strategic petroleum reserve for the use of state and local governments, the immediate implementation of a national Feed-in Tariff mandating that electric utilities pay 3 percent above market rates for all surplus electricity generated from renewable sources, a thorough assessment of soil conditions nationwide, and an emergency action plan for soil restoration and sustainable agriculture.

Book Description
Insurgent cohesion is central to explaining patterns of violence, the effectiveness of counterinsurgency, and civil war outcomes. Cohesive insurgent groups produce more effective war-fighting forces and are more credible negotiators; organizational cohesion shapes both the duration of wars and their ultimate resolution. In Networks of Rebellion, Paul Staniland explains why insurgent leaders differ so radically in their ability to build strong organizations and why the cohesion of armed groups changes over time during conflicts. He outlines a new way of thinking about the sources and structure of insurgent groups, distinguishing among integrated, vanguard, parochial, and fragmented groups. Staniland compares insurgent groups, their differing social bases, and how the nature of the coalitions and networks within which these armed groups were built has determined their discipline and internal control. He examines insurgent groups in Afghanistan, 1975 to the present day, Kashmir (1988–2003), Sri Lanka from the 1970s to the defeat of the Tamil Tigers in 2009, and several communist uprisings in Southeast Asia during the Cold War. The initial organization of an insurgent group depends on the position of its leaders in prewar political networks. These social bases shape what leaders can and cannot do when they build a new insurgent group. Counterinsurgency, insurgent strategy, and international intervention can cause organizational change. During war, insurgent groups are embedded in social ties that determine they how they organize, fight, and negotiate; as these ties shift, organizational structure changes as well.

KELLOCK PSYCH TEXTBOOKS FOR A LOST GENERATION: MANUAL FOR SUPERIOR MEN. THE FULL COLLECTED WORKS OF KAREN KELLOCK. NEW PSYCH THEORY by Karen Kellock Ph.D., Psychology & Proverb Author. The cause of mental illness is other people: be shocked into a new world view seeing mental illness in a new light. Elite Review: "Koestler [1962] shows all discoveries blend art with science. Vivid poetic images combined with rock-solid psychology show the tyranny of groups vs. the individual: collective insanity, the contagion of lunacy. What does it take to be a champion in a sea of sharks? That’s the essence of this work. The writing is subtle, witty, clever and highly accurate. The therapy: open the book anywhere". Mansell Pattison M.D., Postdoctoral Sponsor at UCI School of Medicine, Dept. of Psychiatry. Karen Kellock received her Ph.D. from University of California, Irvine and was a postdoctoral fellow at the Medical School, Dept. of Psychiatry [NIAAA and NIMH grants] to develop a theory of System Pathology: the Debris Theory of Disease, presented in 120 books and 22 textbooks for the general public. The theory has a general formula: All disease is obstruction, all recovery is elimination, all success is attraction. The three obstructions are people, habit and food. Remove your obstruction and snap to your goals, waiting in the wings. "An integrator and discoverer. As her Ph.D. advisor it's WOW on pathological systems theory, a sudden eye-opener". Doug Chalmers, Ph.D., UCI Dept. of Psychology "Brilliance inspires thinking in new realms by debunking old myths. A true theoretician ties everything together so we can see the whole".

Book Description
Collapse Operations for First Responders discusses in detail the common warning signs of structural collapse and what to do when they are encountered, providing a practical, hands-on approach to operating safely and effectively in collapse rescue situations. Discussion is chiefly directed toward one of the most common types of structures around the country, wood and brick-and-joist (ordinary-constructed) buildings, known as URM (unreinforced masonry) construction. Various types of shoring and cribbing techniques vital to collapse rescue operations, as well as void size-up, safety at collapse operations, tools used in voids, and void procedures are explored. Collapse Operations for First Responders is a must-have resource for firefighters, officers, chiefs, and technical rescue response personnel.

Book Description
This new Handbook examines the issues, challenges, and debates surrounding the problem of security in Africa. Africa is home to most of the world's current conflicts, and security is a key issue. However, African security can only be understood by employing different levels of analysis: the individual (human security), the state (national/state security), and the region (regional/international security). Each of these levels provides analytical tools for understanding what could be called the "African security predicament" and these debates are animated by the "new security" issues: immigration, small arms transfers, gangs and domestic crime, HIV/AIDS, transnational crime, poverty, and environmental degradation. African security therefore not only presents concrete challenges for international security but provides a real-world context for challenging conventional conceptions of security. Drawing together contributions from a wide range of key thinkers in the field, the Routledge Handbook of African Security engages with these debates, and is organized into four parts: Part I: The African security predicament in the twenty-first century; Part II: Understanding conflict in Africa; Part III: Regionalism and Africa; Part IV: External influences. This Handbook will be of great interest to students of African politics, human security, global security, war and conflict studies, peacebuilding, and IR in general.

Book Description
These volumes include a collection of authoritative articles covering the most active areas of prokaryotic biomembrane investigations, and will provide a great service not only to those interested in the field but also to microbiologists in general. These monographs will also serve to focus attention on prokaryotic membranes that are so often ignored by eukaryoticmembraneologists and proved an excellent reference source for many years to come.
