In the 1980s, as HIV/AIDS ravaged queer communities and communities of color in the United States and beyond, a straight white teenager named Ryan White emerged as the face of the epidemic. Diagnosed with hemophilia at birth, Ryan contracted HIV through contaminated blood products. In 1985, he became a household name after he was barred from attending his Indiana middle school. As Ryan appeared on nightly news broadcasts and graced the covers of popular magazines, he was embraced by music icons and well-known athletes, achieving a curious kind of stardom. Analyzing his struggle and celebrity, Paul M. Renfro's powerful biography grapples with the contested meanings of Ryan's life, death, and afterlives. As Renfro argues, Ryan's fight to attend school forced the American public to reckon with prevailing misconceptions about the AIDS epidemic. Yet his story also reinforced the hierarchies at the heart of the AIDS crisis. Because the "innocent" Ryan had contracted HIV "through no fault of his own," as many put it, his story was sometimes used to blame presumably "guilty" populations for spreading the virus. Reexamining Ryan's story through this lens, Renfro reveals how the consequences of this stigma continue to pervade policy and cultural understandings of HIV/AIDS today.
Beginning with Etan Patz's disappearance in Manhattan in 1979, a spate of high-profile cases of missing and murdered children stoked anxieties about the threats of child kidnapping and exploitation. Publicized through an emerging twenty-four-hour news cycle, these cases supplied evidence of what some commentators dubbed "a national epidemic" of child abductions committed by "strangers." In this book, Paul M. Renfro narrates how the bereaved parents of missing and slain children turned their grief into a mass movement and, alongside journalists and policymakers from both major political parties, propelled a moral panic. Leveraging larger cultural fears concerning familial and national decline, these child safety crusaders warned Americans of a supposedly widespread and worsening child kidnapping threat, erroneously claiming that as many as fifty thousand American children fell victim to stranger abductions annually. The actual figure was (and remains) between one hundred and three hundred, and kidnappings perpetrated by family members and acquaintances occur far more frequently. Yet such exaggerated statistics-and the emotionally resonant images and narratives deployed behind them-led to the creation of new legal and cultural instruments designed to keep children safe and to punish the "strangers" who ostensibly wished them harm. Ranging from extensive child fingerprinting drives to the milk carton campaign, from the AMBER Alerts that periodically rattle Americans' smart phones to the nation's sprawling system of sex offender registration, these instruments have widened the reach of the carceral state and intensified surveillance practices focused on children. Stranger Danger reveals the transformative power of this moral panic on American politics and culture, showing how ideas and images of endangered childhood helped build a more punitive American state.
Stabilization and Dynamic of Premixed Swirling Flames: Prevaporized, Stratified, Partially, and Fully Premixed Regimes focuses on swirling flames in various premixed modes (stratified, partially, fully, prevaporized) for the combustor, and development and design of current and future swirl-stabilized combustion systems. This includes predicting capabilities, modeling of turbulent combustion, liquid fuel modeling, and a complete overview of stabilization of these flames in aeroengines. The book also discusses the effects of the operating envelope on upstream fresh gases and the subsequent impact of flame speed, combustion, and mixing, the theoretical framework for flame stabilization, and fully lean premixed injector design. Specific attention is paid to ground gas turbine applications, and a comprehensive review of stabilization mechanisms for premixed, partially-premixed, and stratified premixed flames. The last chapter covers the design of a fully premixed injector for future jet engine applications. - Features a complete view of the challenges at the intersection of swirling flame combustors, their requirements, and the physics of fluids at work - Addresses the challenges of turbulent combustion modeling with numerical simulations - Includes the presentation of the very latest numerical results and analyses of flashback, lean blowout, and combustion instabilities - Covers the design of a fully premixed injector for future jet engine applications
