Out of the Depths - The Story of a Child of Buchenwald who Returned Home at last (Paperback): Rabbi Israel Meir Lau Out of the Depths - The Story of a Child of Buchenwald who Returned Home at last (Paperback)
Rabbi Israel Meir Lau; Foreword by Elie Wiesel, Shimon Peres
R491 R407 Discovery Miles 4 070 Save R84 (17%) Ships in 9 - 15 working days

A moving account of survival and faith from Israel Meir Lau, a Holocaust survivor and former Chief Rabbi of Israel, with forewords by former President of Israel Shimon Peres and the bestselling author of Night, Elie Wiesel—both Nobel Peace Prize laureates.   One of the youngest survivors of Buchenwald, Israel Meir Lau was just eight years old when the camp was liberated in 1945. Descended from a 1,000-year unbroken chain of rabbis, he grew up to become Chief Rabbi of Israel--and like many of the great rabbis, Lau is a master storyteller. Out of the Depths is his harrowing, miraculous, and inspiring account of life in one of the Nazis’ deadliest concentration camps and how he managed to survive against all possible odds. Lau, who lost most of his family in the Holocaust, also chronicles his life after the war, including his emigration to Mandate Palestine during a period that coincides with the development of the State of Israel. The story continues through the present day, with that once-lost boy of eight now a brilliant, charismatic, and world-revered figure who has visited with three popes, the Dalai Lama, Nelson Mandela, and countless global leaders, including Queen Elizabeth, Ronald Reagan, Barack Obama, and Tony Blair.   Lau’s insightful reflections on his experiences during the Holocaust and World War II make Out of the Depths a compelling tribute to the strength and resilience of the human spirit. Originally published in Hebrew under the title Do Not Raise a Hand Against the Boy, this is a deeply inspiring and powerful memoir for readers of Holocaust books such as The Daughter of Auschwitz and Man’s Search for Meaning.

Grant Hamilton, Carolyn Lau
R4,879 Discovery Miles 48 790 Ships in 10 - 15 working days

This book works to delineate some of the major routes by which science and art intersect. Structured according to the origin myths of the posthuman that continue to shape the idea of the human in our technological modernity, this volume gives space to narratives of alter-modernity that resonate with Ursula K. Le Guin’s call for a new kind of story which exposes the violence and exploitation driven by a sustained belief in human exceptionalism, anthropocentrism, and cultural superiority. In this context, the posthuman myths of multispecies flourishing given in this collection, which are situated across a range of historical times and locations, and media and modalities, are to be thought of as kernels of possible futures that can only be realized through collective endeavour.

Buen Vivir and the Challenges to Capitalism in Latin America: Henry Veltmeyer, Edgar Lau Buen Vivir and the Challenges to Capitalism in Latin America
Henry Veltmeyer, Edgar Lau
R1,263 Discovery Miles 12 630 Ships in 9 - 15 working days

This book explores the battleground between neoliberal capitalist development processes in Latin America and the challenges to these systems that can be found through innovative community-driven buen vivir/vivir bien initiatives. In the current climate of worldwide capitalist development, Latin America is caught between left-leaning proposals for progressive policies towards a more inclusive form of development, and the re-emergence of harsh austerity measures, neoliberal reforms and right-wing populism. Divided into two parts, this book first provides a retrospective analysis of the advance of resource-seeking ‘extractive’ capital across the continent since the 1990s. The second part goes on to focus on forward-looking challenges to neoliberal capitalist development, focusing in particular on the indigenous notion of buen vivir/vivir bien – the concept of ‘living well’ in social solidarity and harmony with nature. Drawing on cases in Mexico and Venezuela, the book argues that it will be through these new approaches to social change that we will move beyond development as we know it towards a more inclusive form of ‘postdevelopment’. Looking hopefully towards this future of development, this collection offers an essential analysis of the vortex of social change currently consuming Latin America and will be key reading for advanced scholars and researchers in the fields of Development Studies, Latin America Studies, Politics, and Social Change.

Responding to Mass Atrocities in Africa - Protection First and Justice Later: Raymond Kwun-Sun Lau Responding to Mass Atrocities in Africa - Protection First and Justice Later
Raymond Kwun-Sun Lau
R1,289 Discovery Miles 12 890 Ships in 12 - 17 working days

This book explores the relationship between the Responsibility to Protect (R2P) and the International Criminal Court (ICC), challenging the assumption that they are always mutually reinforcing or complementary, and examining instead the many tensions which arise between the immediate imperative of saving lives, and the more long-term prospect of punishing perpetrators and preventing future conflicts through deterrence. Around the world, audiences in the mid-1990s watched the mass atrocities unfolding in Rwanda and Srebrenica in horror and disbelief. Emerging from these disasters came an international commitment to safeguard and protect vulnerable communities, as laid out in the R2P principle, and an international responsibility to punish perpetrators, with the establishment of the ICC. The book provides context-independent proposals for resolving contradictions between the two principles, suggesting that focusing on timing and sequencing in invoking international R2P and ICC actions could facilitate the easing of tensions. Drawing on examples from Uganda, Kenya, and Darfur, the book applies International Relations concepts and theories in order to deepen our understanding of international responses to mass atrocities. Ultimately the book concludes that a 'Protection First, Justice Later' sequence approach is necessary for managing the tension and facilitating more effective and consistent international responses. This book makes an important contribution to discussions and debates surrounding international responses to genocide and mass atrocities. It will be of special interest to scholars, students and policymakers in International Relations, Global Governance, African Studies, International Development, Human Rights and International Criminal Law.

R3,879 Discovery Miles 38 790 Ships in 12 - 17 working days

Since the 1970's, there has been a great deal of research effort spent on studying
chaotic systems and the properties of the chaotic signals generated. Characterized by their wideband, impulse-like autocorrelation and low cross-correlation properties, chaotic signals are useful spread-spectrum signals for carrying digital information. Spectrum spreading has become one of the most popular modulation techniques for high-speed wireless communications. It makes use of signals of very wide bandwidth to carry information at relatively low data rates, and possesses advantages such as low probability of interception, resistance to jamming, multiple-access capability and mitigation to multipath effect, which are particularly important in a wireless scenario. In addition to enjoying the aforementioned benefits, chaotic signals can be generated using simple circuitries, thus lowering the cost of transceivers.
Early study of chaos-based communication systems was focused on a single-user case. In the past few years, more effort has been put on investigating systems with multiple-access capability, which is a key feature of spread-spectrum communication systems. This book presents a detailed study of some multiple-access schemes used for chaos-based communications, and evaluates their performance. In addition, the effectiveness of the multiuser detection techniques, whose primary objective is to reduce interference between users and hence improve performance, is evaluated in the context of multiple-access digital communication systems.
* Hot research topic
* Describes communication technologies for the future
* Authors among the pioneers researching in chaos-based communications
