Revolutionary Guerrilla Warfare: Theories, Doctrines, and Contexts

by Sam C. Sarkesian

'Revolution' is a word that causes fear in some, exhilaration in others, and confusion in most. Originally used to describe a restoration, it eventually came to mean a sweeping, sudden attack on an existing order. Human history has borne witness to a variety of national and social revolutions - population revolution, revolution of ideas, technological revolution, and revolution in education. Simultaneously, there has been a proliferation of literature on revolution, armed struggle, and violence aimed at unseating policies and leadership of governments and societies.Revolutionary struggles are more than simply armed internal conflict; they involve the essence of the political system. The desire to make such phenomena understandable often leads to oversimplification. Attempts to encompass their multi-dimensional nature, on the other hand, can become immersed in complexities, ambiguities, and misinterpretations. The perspective of this classic volume, available in paperback for the first time, is that revolution is here to stay. Guerrilla warfare, according to Sarkesian, is a particularly useful strategy for the weak, the frustrated, the alienated, and seekers of power against existing regimes. The collected works in this volume examine the social roots of revolution, development of strategy and tactics, practice in city and countryside, dilemmas of attackers and defenders.The actors and thinkers collected and analyzed here range from leading political analysts, anthropologists, sociologists, historians, and officials as well as practitioners of guerrilla warfare. This core text with primary sources in the area of war, revolution, and insurgence develops an understanding of revolution, traces the growth of guerilla doctrine, and studies the specifics of revolutionary and counterrevolutionary guerilla warfare.

Revolutionary Networks: The Business and Politics of Printing the News, 1763–1789 (Studies in Early American Economy and Society from the Library Company of Philadelphia)

by Joseph M. Adelman

An engrossing and powerful story about the influence of printers, who used their commercial and political connections to directly shape Revolutionary political ideology and mass mobilization.Honorable Mention, St. Louis Mercantile Library Prize, Bibliographical Society of AmericaDuring the American Revolution, printed material, including newspapers, pamphlets, almanacs, and broadsides, played a crucial role as a forum for public debate. In Revolutionary Networks, Joseph M. Adelman argues that printers—artisans who mingled with the elite but labored in a manual trade—used their commercial and political connections to directly shape Revolutionary political ideology and mass mobilization. Going into the printing offices of colonial America to explore how these documents were produced, Adelman shows how printers balanced their own political beliefs and interests alongside the commercial interests of their businesses, the customs of the printing trade, and the prevailing mood of their communities. Adelman describes how these laborers repackaged oral and manuscript compositions into printed works through which political news and opinion circulated. Drawing on a database of 756 printers active during the Revolutionary era, along with a rich collection of archival and printed sources, Adelman surveys printers' editorial strategies. Moving chronologically through the era of the American Revolution and to the war's aftermath, he details the development of the networks of printers and explains how they contributed to the process of creating first a revolution and then the new nation.By underscoring the important and intertwined roles of commercial and political interests in the development of Revolutionary rhetoric, this book essentially reframes our understanding of the American Revolution. Printers, Adelman argues, played a major role as mediators who determined what rhetoric to amplify and where to circulate it. Offering a unique perspective on the American Revolution and early American print culture, Revolutionary Networks reveals how these men and women managed political upheaval through a commercial lens.

Today, technology is increasingly integrated into every aspect of our lives, rewiring our homes, our jobs, and even our brains. Most important, it presents an opportunity to rewire education to enrich and strengthen our schools, children, and societyIn Rewiring Education, Couch shares the professional lessons he's learned during his 50-plus years in education and technology. He takes us behind Apple's major research study, Apple Classrooms of Tomorrow (ACOT), and its follow-up (ACOT 2), highlighting the powerful effects of the Challenge-Based Learning framework. Going beyond Apple's walls, he also introduces us to some of the most extraordinary parents, educators, and entrepreneurs from around the world who have ignored the failed promises of memorization and, instead, utilize new science-backed methods and technologies that benefit all children, from those who struggle to honor students. Rewiring Education presents a bold vision for the future of education, looking at promising emerging technologies and how we—as parents, teachers, and voters—can ensure children are provided with opportunities and access to the relevant, creative, collaborative, and challenging learning environments they need to succeed.

RF Analog Impairments Modeling for Communication Systems Simulation

by Lydi Smaini

With the growing complexity of personal mobile communication systems demanding higher data-rates and high levels of integration using low-cost CMOS technology, overall system performance has become more sensitive to RF analog front-end impairments. Designing integrated transceivers requires a thorough understanding of the whole transceiver chain including RF analog front-end and digital baseband. Communication system engineers have to include RF analog imperfections in their simulation benches in order to study and quantify their impact on the system performance.Here the author explores key RF analog impairments in a transceiver and demonstrates how to model their impact from a communication system design view-point. He discusses the design aspects of the front end of transceivers (both receivers and transmitters) and provides the reader with a way to optimize a complex mixed-signal platform by taking into account the characteristics of the RF/analog front-end.Key features of this book include:Practical examples illustrated by system simulation results based on WiFi and mobile WiMAX OFDM transceiversAn overview of the digital estimation and compensation of the RF analog impairments such as power amplifier distortion, quadrature imbalance, and carrier and sampling frequency offsetsAn exposition of the challenges involved in the design of both RF analog circuits and DSP communication circuits in deep submicron CMOS technologyMATLAB® codes for RF analog impairments models hosted on the companion websiteUniquely the book bridges the gap between RFIC design specification needs and communication systems simulation, offering readers RF analog impairments modeling knowledge and a comprehensive approach to unifying theory and practice in system modelling. It is of great value to communication systems and DSP engineers and graduate students who design communication processing engines, RF/analog systems and IC design engineers involved in the design of communication platforms.
