"In Cracked Media, Caleb Kelly explores how the deliberate utilization of the normally undesirable (a crack, a break) has become the site of productive creation. Cracked media, Kelly writes, slides across disciplines, through music, sound, and noise. Cracked media encompasses everything from Cage's silences and indeterminacies, to Paik's often humorous tape works, to the cold and clean sounds of digital glitch in the work of Tone and Oval. Kelly offers a detailed historical account of these practices, arguing that they can be read as precursors to contemporary new media.".
The Emergence of Crack Cocaine Abuse by Edith Fairman Cooper Pdf
Cocaine was once considered the elite's drug, with a price so high that only the very wealthy could afford it, and thought by many to be 'safe'. But during the 1980s, a dangerous and cheap derivative began appearing on the street. This drug, crack, is a cocaine free-base produced relatively safely and easily. Because of its low production costs, crack became popular among the lower classes, leading to an epidemic in the late 1980s, with estimates that over one million people used crack cocaine. The drug's name became synonymous with gangs, crime, and violence. Because of the intensity and apparent suddenness of the crack crisis, people began to wonder if there were any warning signs public officials missed and how exactly crack spread across the nation. Some even floated the theory that agencies like the CIA and FBI encouraged the use of crack in inner cities. No matter where it came from, crack is a menace that, though no longer 'epidemic', must be combated along with all other illegal drugs. This book makes a close examination of the development, responses to, and effect of the crack cocaine crisis in the United States. Included are descriptions of cocaine, crack, and the free-basing process. Also examined are the health questions surrounding the abuse problems and the allegations that governmental authorities had advance knowledge of crack. With the war on drugs a perpetual and critical battle in America, the facts and analyses presented here are of paramount importance to the understanding of a major issue of society's safety.
Cracked Coverage by Jimmie Lynn Reeves,Richard Campbell Pdf
Carefully documenting the deceptions and excesses of television news coverage of the so-called cocaine epidemic, Cracked Coverage stands as a bold indictment of the backlash politics of the Reagan coalition and its implicit racism, the mercenary outlook of the drug control establishment, and the enterprising reporting of crusading journalism. Blending theoretical and empirical analyses, Jimmie L. Reeves and Richard Campbell explore how TV news not only interprets "reality" in ways that reflect prevailing ideologies, but is in many respects responsible for constructing that reality. Their examination of the complexity of television and its role in American social, cultural, and political conflict is focused specifically on the ways in which American television during the Reagan years helped stage and legitimate the "war on drugs," one of the great moral panics of the postwar era. The authors persuasively argue, for example, that powder cocaine in the early Reagan years was understood and treated very differently on television and by the state than was crack cocaine, which was discovered by the news media in late 1985. In their critical analysis of 270 news stories broadcast between 1981 and 1988, Reeves and Campbell demonstrate a disturbing disparity between the earlier presentation of the middle- and upper-class "white" drug offender, for whom therapeutic recovery was an available option, and the subsequent news treatment of the inner-city "black" drug delinquent, often described as beyond rehabilitation and subject only to intensified strategies of law and order. Enlivened by provocative discussions of Nancy Reagan's antidrug activism, the dramatic death of basketball star Len Bias, and the myth of the crack baby, the book argues that Reagan's war on drugs was at heart a political spectacle that advanced the reactionary agenda of the New and Religious Right--an agenda that dismissed social problems grounded in economic devastation as individual moral problems that could simply be remedied by just saying "no." Wide ranging and authoritative, Cracked Coverage: Television News, the Anti-Cocaine Crusade, and the Reagan Legacy is a truly interdisciplinary work that will attract readers across the humanities and social sciences in addition to students, scholars, journalists, and policy makers interested in the media and drug-related issues.
Mechanics of Composite Materials by Zvi Hashin,Carl T. Herakovich Pdf

Fracture Mechanics in Layered and Graded Solids by Tian Xiaohong,Quentin Zhong Qi Yue Pdf
Mechanical responses of solid materials are governed by their material properties. The solutions for estimating and predicting the mechanical responses are extremely difficult, in particular for non-homogeneous materials. Among these, there is a special type of materials whose properties are variable only along one direction, defined as graded materials or functionally graded materials (FGMs). Examples are plant stems and bones. Artificial graded materials are widely used in mechanical engineering, chemical engineering, biological engineering, and electronic engineering. This work covers and develops boundary element methods (BEM) to investigate the properties of realistic graded materials.It is a must have for practitioners and researchers in materials science, both academic and in industry. Covers analysis of properties of graded materials. Presents solutions based methods for analysis of fracture mechanics. Presents two types of boundary element methods for layered isotropic materials and transversely isotropic materials. Written by two authors with extensive international experience in academic and private research and engineering.
Fracture Mechanics and Crack Growth by Naman Recho Pdf
This book presents recent advances related to the following two topics: how mechanical fields close to material or geometrical singularities such as cracks can be determined; how failure criteria can be established according to the singularity degrees related to these discontinuities. Concerning the determination of mechanical fields close to a crack tip, the first part of the book presents most of the traditional methods in order to classify them into two major categories. The first is based on the stress field, such as the Airy function, and the second resolves the problem from functions related to displacement fields. Following this, a new method based on the Hamiltonian system is presented in great detail. Local and energetic approaches to fracture are used in order to determine the fracture parameters such as stress intensity factor and energy release rate. The second part of the book describes methodologies to establish the critical fracture loads and the crack growth criteria. Singular fields for homogeneous and non-homogeneous problems near crack tips, v-notches, interfaces, etc. associated with the crack initiation and propagation laws in elastic and elastic-plastic media, allow us to determine the basis of failure criteria. Each phenomenon studied is dealt with according to its conceptual and theoretical modeling, to its use in the criteria of fracture resistance; and finally to its implementation in terms of feasibility and numerical application. Contents 1. Introduction. Part 1: Stress Field Analysis Close to the Crack Tip 2. Review of Continuum Mechanics and the Behavior Laws. 3. Overview of Fracture Mechanics. 4. Fracture Mechanics. 5.

LONGLISTED FOR THE NATIONAL BOOK AWARD • A “vivid and frank” (NPR) account of the crack cocaine era and a community’s ultimate resilience, told through a cast of characters whose lives illuminate the dramatic rise and fall of the epidemic “A master class in disrupting a stubborn narrative, a monumental feat for the fraught subject of addiction in Black communities.”—The Washington Post “A poignant and compelling re-examination of a tragic era in America history . . . insightful . . . and deeply moving.”—Bryan Stevenson, author of the #1 New York Times bestseller Just Mercy ONE OF THE NEW YORK PUBLIC LIBRARY AND VULTURE’S TEN BEST BOOKS OF THE YEAR A BEST BOOK OF THE YEAR: Time, The Washington Post, NPR, Chicago Public Library, Publishers Weekly, She Reads, Electric Lit, The Mary Sue The crack epidemic of the 1980s and 1990s is arguably the least examined crisis in American history. Beginning with the myths inspired by Reagan’s war on drugs, journalist Donovan X. Ramsey’s exacting analysis traces the path from the last triumphs of the Civil Rights Movement to the devastating realities we live with today: a racist criminal justice system, continued mass incarceration and gentrification, and increased police brutality. When Crack Was King follows four individuals to give us a startling portrait of crack’s destruction and devastating legacy: Elgin Swift, an archetype of American industry and ambition and the son of a crack-addicted father who turned their home into a “crack house”; Lennie Woodley, a former crack addict and sex worker; Kurt Schmoke, the longtime mayor of Baltimore and an early advocate of decriminalization; and Shawn McCray, community activist, basketball prodigy, and a founding member of the Zoo Crew, Newark’s most legendary group of drug traffickers. Weaving together riveting research with the voices of survivors, When Crack Was King is a crucial reevaluation of the era and a powerful argument for providing historically violated communities with the resources they deserve.
Popular party drugs from the 1980s to the present, crack and its more expensive, purer form, cocaine, have gripped users both rich and poor in the United States. Crack examines the psychological, biomedical, social, and legal aspects of this highly
Humphries (sociology, anthropology, and criminal justice, Rutgers U.) analyzes reactions to crack cocaine use, particularly by women, and critiques the policies instituted to combat it. She argues that policies of zero tolerance, mandatory sentences, and interdiction have failed to reduce drug use, increased the sense of persecution among the urban poor, and contributed to court and prison overcrowding.
