Black Networked Resistance: Strategic Rearticulations in the Digital Age
by Raven Simone Maragh-LloydBlack Networked Resistance explores the creative range of Black digital users and their responses to varying forms of oppression, utilizing cultural, communicative, political, and technological threads both on and offline. Raven Maragh-Lloyd demonstrates how Black users strategically rearticulate their responses to oppression in ways that highlight Black publics’ historically rich traditions and reveal the shifting nature of both dominance and resistance, particularly in the digital age. Through case studies and interviews, Maragh-Lloyd reveals the malleable ways resistance can take shape and the ways Black users artfully demonstrate such modifications of resistance through strategies of survival, reprieve, and community online. Each chapter grounds itself in a resistance strategy, such as Black humor, care, or archiving, to show the ways that Black publics reshape strategies of resistance over time and across media platforms. Linking singular digital resistance movements while arguing for Black publics as strategic content creators who connect resistance strategies from our past to suit our present needs, Black Networked Resistance encourages readers to create and cultivate lasting communities necessary for social and political change by imagining a future of joy, community, and agency through their digital media practices.

Black Power TV
by Devorah HeitnerIn Black Power TV, Devorah Heitner chronicles the emergence of Black public affairs television starting in 1968. She examines two local shows, New York's Inside Bedford-Stuyvesant and Boston's Say Brother, and the national programs Soul! and Black Journal. These shows offered viewers radical and innovative programming: the introspections of a Black police officer in Harlem, African American high school students discussing visionary alternatives to the curriculum, and Miriam Makeba comparing race relations in the United States to apartheid in South Africa. While Inside Bedford-Stuyvesant and Say Brother originated from a desire to contain Black discontent during a period of urban uprisings and racial conflict, these shows were re-envisioned by their African American producers as venues for expressing Black critiques of mainstream discourse, disseminating Black culture, and modeling Black empowerment. At the national level, Soul! and Black Journal allowed for the imagining of a Black nation and a distinctly African American consciousness, and they played an influential role in the rise of the Black Arts Movement. Black Power TV reveals how regulatory, activist, and textual histories are interconnected and how Black public affairs television redefined African American representations in ways that continue to reverberate today.
Black Ranching Frontiers
by Andrew SluyterIn this groundbreaking book Andrew Sluyter demonstrates for the first time that Africans played significant creative roles in establishing open-range cattle ranching in the Americas. In so doing, he provides a new way of looking at and studying the history of land, labor, property, and commerce in the Atlantic world. Sluyter shows that Africans’ ideas and creativity helped to establish a production system so fundamental to the environmental and social relations of the American colonies that the consequences persist to the present. He examines various methods of cattle production, compares these methods to those used in Europe and the Americas, and traces the networks of actors that linked that Atlantic world. The use of archival documents, material culture items, and ecological relationships between landscape elements make this book a methodologically and substantively original contribution to Atlantic, African-American, and agricultural history.
Black Representation in the Science Curriculum: Implications for Identity, Culture, Belonging, and Curriculum Development (Routledge Research in STEM Education)
by Catherine L. QuinlanThis book sheds new light on the importance of Black representation in the US science curriculum from a social, cultural, cognitive, and scientific perspective.Weaving together content, new methodologies, and science education pedagogies, it opens up new space for the meaningful inclusion of the science capital and cultural capital of Black people in the US science curricula. Drawing on ethnographic interviews with African American Gullah-Geechee and research outcomes from qualitative and quantitative research and curriculum development, it brings home the importance of attending to a sense of belonging in the K-12 science curricula toward lasting equity and inclusion. The author uses applied cognitive psychology theories as frameworks to show how perceptions about the perceived value of Black representation as a way of knowing is influenced by identity, culture, and social schemas.Incorporating new methodologies and approaches focused on inclusion and belonging, it will appeal to scholars, researchers, upper-level and post-graduate students with interest in STEM education, race and ethnicity in education, equity, and research methods in education.
Black Rice: Research, History and Development

The book intends to cover all aspects of black rice; from research, history, to its development. As such, the book will be suitable for both rice researchers and non-professionals who want to know more about this unique rice crop.
Black Rice: The African Origins Of Rice Cultivation In The Americas
by Judith A. CarneyFew Americans identify slavery with the cultivation of rice, yet rice was a major plantation crop during the first three centuries of settlement in the Americas. Rice accompanied African slaves across the Middle Passage throughout the New World to Brazil, the Caribbean, and the southern United States. By the middle of the eighteenth century, rice plantations in South Carolina and the black slaves who worked them had created one of the most profitable economies in the world. Black Rice tells the story of the true provenance of rice in the Americas. It establishes, through agricultural and historical evidence, the vital significance of rice in West African society for a millennium before Europeans arrived and the slave trade began. The standard belief that Europeans introduced rice to West Africa and then brought the knowledge of its cultivation to the Americas is a fundamental fallacy, one which succeeds in effacing the origins of the crop and the role of Africans and African-American slaves in transferring the seed, the cultivation skills, and the cultural practices necessary for establishing it in the New World. In this vivid interpretation of rice and slaves in the Atlantic world, Judith Carney reveals how racism has shaped our historical memory and neglected this critical African contribution to the making of the Americas.

Blackbody Radiation: A History of Thermal Radiation Computational Aids and Numerical Methods (Optical Sciences and Applications of Light)
by Sean M. Stewart R. Barry JohnsonShelving Guide: Electrical Engineering In 1900 the great German theoretical physicist Max Planck formulated a correct mathematical description of blackbody radiation. Today, understanding the behavior of a blackbody is of importance to many fields including thermal and infrared systems engineering, pyrometry, astronomy, meteorology, and illumination. This book gives an account of the development of Planck’s equation together with many of the other functions closely related to it. Particular attention is paid to the computational aspects employed in the evaluation of these functions together with the various aids developed to facilitate such calculations. The book is divided into three sections. Section I – Thermal radiation and the blackbody problem are introduced and discussed. Early developments made by experimentalists and theoreticians are examined as they strove to understand the problem of the blackbody. Section II – The development of Planck’s equation is explained as are the all-important fractional functions of the first and second kinds which result when Planck’s equation is integrated between finite limits. A number of theoretical developments are discussed that stem directly from Planck’s law, as are the various computational matters that arise when numerical evaluation is required. Basic elements of radiometry that tie together and use many of the theoretical and computational ideas developed is also presented. Section III – A comprehensive account of the various computational aids such as tables, nomograms, graphs, and radiation slide rules devised and used by generations of scientists and engineers when working with blackbody radiation are presented as are more recent aids utilizing computers and digital devices for real-time computations. Scientists and engineers working in fields utilizing blackbody sources will find this book to be a valuable guide in understanding many of the computational aspects and nuances associated with Planck’s equation and its other closely related functions. With over 700 references, it provides an excellent research resource.

Blackett's War
by Stephen BudianskyThe exciting history of a small group of British and American scientists who, during World War II, developed the new field of operational research to turn back the tide of German submarines--revolutionizing the way wars are waged and won. In March 1941, after a year of unbroken and devastating U-boat onslaughts, the British War Cabinet decided to try a new strategy in the foundering naval campaign. To do so, they hired an intensely private, bohemian physicist who was also an ardent socialist. Patrick Blackett was a former navy officer and future winner of the Nobel Prize; he is little remembered today, but he and his fellow scientists did as much to win the war against Nazi Germany as almost anyone else. As director of the World War II antisubmarine effort, Blackett used little more than simple mathematics and probability theory--and a steadfast belief in the utility of science--to save the campaign against the U-boat. Employing these insights in unconventional ways, from the washing of mess hall dishes to the color of bomber wings, the Allies went on to win essential victories against Hitler's Germany. Here is the story of these civilian intellectuals who helped to change the nature of twentieth-century warfare. Throughout, Stephen Budiansky describes how scientists became intimately involved with what had once been the distinct province of military commanders--convincing disbelieving military brass to trust the solutions suggested by their analysis. Budiansky shows that these men above all retained the belief that operational research, and a scientific mentality, could change the world. It's a belief that has come to fruition with the spread of their tenets to the business and military worlds, and it started in the Battle of the Atlantic, in an attempt to outfight the Germans, but most of all to outwit them.
Blackmail Earth
by Bill EvansThe Morning Show's star meteorologist, Jenna Withers, reports on the blistering conditions of a nationwide drought every day. But nothing this alluring young woman has ever experienced can prepare her for the terrifying intersection of extreme weather and extreme politics. After Jenna receives a controversial appointment to a special White House task force on geoengineering, she learns about a lot more than the President's desire to use technology to address global warming. Through old contacts, Jenna hears that Muslim extremists in the Maldives have begun to publicly blame the West for the rising seas that imperil the tiny Pacific island nation. They are planning a suicide bombing that could lead to a sudden and disastrous cooling of the planet. Rick Birk, an aging, alcoholic colleague of Jenna's, is dispatched to report on the turmoil in the Maldives. To his—and everyone else's—shock, he becomes a central – and bizarre – figure in the unfolding panic.News of the Islamist threat sets off an even more horrifying plan in North Korea. The Supreme Leader, desperate for aid, threatens to hold the world hostage with his own, disaster-creating brand of geoengineering, one that takes aim at the skies.Those escalating international tensions are set against the grisly murder of an intriguing Pagan woman in rural New York, Jenna Withers's budding romance with an organic dairy farmer, and a fiercely contested presidential campaign.This swiftly paced tale takes Jenna from the Oval Office to the sandy shores of the Indian Ocean, from the sophisticated set of The Morning Show to her new boyfriend's dusty dairy farm. Filled with fascinating and unusual characters, and told from multiple and deeply moving points of view, Blackmail Earth culminates in a furious battle raging in the heart of Manhattan.At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
Blackout
by John J. NanceNance's new airliner adventure rides on his stock-in-trade of plane crashes, pilot jargon, and airport protocol. Robert McCabe, a reporter investigating a story of possible U.S. government involvement in a recent spate of air crashes, is attempting to elude the goons trying to snatch his info-laden laptop in Hong Kong. His flight out of town, after a brilliant flash blinds the pilots, continues the string of aerial disasters; he and a few others miraculously survive the crash in Vietnam. Then they weather a fusillade from a helicopter and are rescued by FBI agent Kat Bronsky, on the scene just in time, naturally. The harried band then wends its way back across the Pacific, affording them time to theorize about the mayhem to which they've been subjected, while intermittently being shot at by people with poor aim but plenty of perseverance. Undergoing more hairbreadth escapes, they proceed to Seattle, then to Sun Valley, locale of the climactic finale. This will be popular with the aviation-minded, if not with those who expect finesse in their thrillers.
