Signal:08 collects and connects the culture and politics of international Black Power publishing, the 1960s anarchist and antimilitarist illustrations of Vera Williams and Liberation magazine, memorializing those murdered by anti-Sikh violence in India, the agitprop of the Popular Front for the Liberation of Palestine, and the aesthetics and politics of a reenactment of the largest rebellion of enslaved people in US history. Crossing continents and communities, print and performance, Signal weaves a story of how culture is central to social transformation, both yesterday and today. Highlights of the eighth volume of Signal include: Writing for the Revolution: Publishing and Designing Black Power Books by Andrew Fearnley Hope in the Midst of Apathy: Liberation Magazine and the Covers of Vera Williams by Alec Dunn Most of My Heroes: Stamps in Memory of Anti-Sikh Violence by Vijay S. Jodha & S. Ravi Our Code of Morals is Our Revolution: Agit Prop Travel Documents of the Popular Front for the Liberation of Palestine Slave Rebellion Reenactment: An Interview with Dread Scott by Josh MacPhee

An ambulance races to the scene of yet another human tragedy. It could be a road accident, a heart attack, shooting, drowning, suicide, or perhaps a very sick child. Whilst we might experience or witness such events in our lifetime, for paramedics these are routine events. But continual exposure to the work often comes at a significant, sometimes tragic cost to the paramedic and his or her family and friends. In Signal 8, author Erik Schanssema, a retired front-line Australian paramedic, relates some of his experiences and his reactions to them. He provides graphic descriptions of a small sample of the many cases he and his colleagues attended with the intention of providing information rather than shock. Erik opens his heart and soul and tells us frankly and often with humour, albeit sometimes dark, what it was like for him to be a paramedic on the road and how it has affected himas it still does today. The cases he describes are indelibly imprinted on his psyche. He shares his story in an effort to help former, current, and future paramedics and emergency workers who may feel alone or isolated by their experiences and to leave them with a sense of pride in their chosen work and, ultimately, hope. This personal narrative offers a true account of a front-line paramedics experiences with human trauma and his struggle with and survival of grief and posttraumatic stress disorder.

Signal processing arises in the design of such diverse systems as communications, sonar, radar, electrooptical, navigation, electronic warfare and medical imaging systems. It is also used in many physical sciences, such as geophysics, acoustics, and meteorology, among many others. The common theme is to extract and estimate the desired signals, which are mixed with a variety of noise sources and disturbances. Signal processing involves system analysis, random processes, statistical inferences, and software and hardware implementation. The purpose of this book is to provide an elementary, informal introduction, as well as a comprehensive account of principles of random signal processing, with emphasis on the computational aspects. This book covers linear system analysis, probability theory, random signals, spectral analysis, estimation, filtering, and detection theory. It can be used as a text for a course in signal processing by under graduates and beginning graduate students in engineering and science and also by engineers and scientists engaged in signal analysis, filtering, and detection. Part of the book has been used by the author while teaching at the State University of New York at Buffalo and California State University at Long Beach. An attempt has been made to make the book self-contained and straight forward, with the hope that readers with varied backgrounds can appreciate and apply principles of signal processing. Chapter 1 provides a brief review of linear analysis of deterministic signals.
