The globalizing world is increasingly confronting a new category of security issues related to resource availability. The resource environment contains both traditional categories, such as energy, foodstuffs, and water, as well as new technologically related resources, such as rare earth minerals. The essays in this volume emphasize both the uniqueness and the magnitude of these new challenges, while simultaneously acknowledging that cooperation and competition in response to these security concerns occur within the context of both the historical and contemporary international power configurations. Moreover, these challenges are of a global nature and will require global perspectives, global thinking, and innovative global solutions. Krishna-Hensel brings together a wide range of topics focusing on critical resource availability impacting upon global security and the geopolitical ramifications of resource competition. The volume addresses the development of strategic thinking on these issues and underscores the increasing awareness that this is a critical area of concern in the twenty-first century global landscape.

A discussion of the conceptual framework is followed by sections describing the five variables in the national security paradigm: political legitimacy, ethnic and religious tolerance, economic capabilities, natural resources, and military capabilities. Contributors use an interdisciplinary, regional

The frontiers are the future of humanity. Peacefully and sustainably managing them is critical to both security and prosperity in the twenty-first century.

On both sides of the Atlantic, restrictive immigration policies have been framed as security imperatives since the 1990s. This trend accelerated in the aftermath of 9/11 and subsequent terrorist attacks in Europe. In Frontiers of Fear, Ariane Chebel d’Appollonia raises two central questions with profound consequences for national security and immigration policy: First, does the securitization of immigration issues actually contribute to the enhancement of internal security? Second, does the use of counterterrorist measures address such immigration issues as the increasing number of illegal immigrants, the resilience of ethnic tensions, and the emergence of homegrown radicalization? Chebel d’Appollonia questions the main assumptions that inform political agendas in the United States and throughout Europe, analyzing implementation and evaluating the effectiveness of policies in terms of their stated objectives. She argues that the new security-based immigration regime has proven ineffective in achieving its prescribed goals and even aggravated the problems it was supposed to solve: A security/insecurity cycle has been created that results in less security and less democracy. The excesses of securitization have harmed both immigration and counterterrorist policies and seriously damaged the delicate balance between security and respect for civil liberties.

This book provides comprehensive coverage of various Cryptography topics, while highlighting the most recent trends such as quantum, blockchain, lightweight, Chaotic and DNA cryptography. Moreover, this book covers cryptography primitives and its usage and applications and focuses on the fundamental principles of modern cryptography such as Stream Ciphers, block ciphers, public key algorithms and digital signatures. Readers will gain a solid foundation in cryptography and security. This book presents the fundamental mathematical concepts of cryptography. Moreover, this book presents hiding data techniques such as steganography and watermarking. The author also provides a comparative study of the different cryptographic methods, which can be used to solve security problems.

This anthology presents a new study of the worldwide African diaspora by bringing together diverse, multidisciplinary scholarship to address the connectedness of Black subject identities, experiences, issues, themes, and topics, applying them dynamically to diverse locations of the Blackworld—Latin America, the Caribbean, Africa, and the United States. The book underscores three dimensions of African diaspora study. First is a global approach to the African diaspora, showing how globalism underscores the distinctive role that Africa plays in contributing to world history. Second is the extension of African diaspora study in a geographical scope to more robust inclusions of not only the African continent but also to uncharted paths and discoveries of lesser-known diaspora experiences and identities in Latin America and the Caribbean. Third is the illustration of universal unwritten cultural representations of humanities in the African diasporas that show the distinctive humanities’ disciplinary representations of Black diaspora imaginaries and subjectivities. The contributing authors inductively apply these themes to focus the reader’s attention on contemporary localized issues and historical arenas of the African diaspora. They engage their findings to critically analyze the broader norms and dimensions that characterize a given set of interrelated criteria that have come to establish parameters that increasingly standardize African diaspora studies.
