Book Description
The fascinating—and eerily timely—tale of the forgotten Depression-era psychologists who launched the modern science of childhood development. “Doomed from birth” was how psychologist Harold Skeels described two toddler girls at the Iowa Soldiers’ Orphans’ Home in Davenport, Iowa, in 1934. Their IQ scores, added together, totaled just 81. Following prevailing eugenic beliefs of the times, Skeels and his colleague Marie Skodak assumed that the girls had inherited their parents’ low intelligence and were therefore unfit for adoption. The girls were sent to an institution for the “feebleminded” to be cared for by “moron” women. To Skeels and Skodak’s astonishment, under the women’s care, the children’s IQ scores became normal. Now considered one of the most important scientific findings of the twentieth century, the discovery that environment shapes children’s intelligence was also one of the most fiercely contested—and its origin story has never been told. In The Orphans of Davenport, psychologist and esteemed historian Marilyn Brookwood chronicles how a band of young psychologists in 1930s Iowa shattered the nature-versus-nurture debate and overthrew long-accepted racist and classist views of childhood development. Transporting readers to a rural Iowa devastated by dust storms and economic collapse, Brookwood reveals just how profoundly unlikely it was for this breakthrough to come from the Iowa Child Welfare Research Station. Funded by the University of Iowa and the Rockefeller Foundation, and modeled on America’s experimental agricultural stations, the Iowa Station was virtually unknown, a backwater compared to the renowned psychology faculties of Stanford, Harvard, and Princeton. Despite the challenges they faced, the Iowa psychologists replicated increased intelligence in thirteen more “retarded” children. When Skeels published their incredible work, America’s leading psychologists—eugenicists all—attacked and condemned his conclusions. The loudest critic was Lewis M. Terman, who advocated for forced sterilization of low-intelligence women and whose own widely accepted IQ test was threatened by the Iowa research. Terman and his opponents insisted that intelligence was hereditary, and their prestige ensured that the research would be ignored for decades. Remarkably, it was not until the 1960s that a new generation of psychologists accepted environment’s role in intelligence and helped launch the modern field of developmental neuroscience.. Drawing on prodigious archival research, Brookwood reclaims the Iowa researchers as intrepid heroes and movingly recounts the stories of the orphans themselves, many of whom later credited the psychologists with giving them the opportunity to forge successful lives. A radiant story of the power and promise of science to better the lives of us all, The Orphans of Davenport unearths an essential history at a moment when race science is dangerously resurgent.

Book Description
This book features the latest advances and future trends in water science and technology. It also discusses the scientific popularization and quantitative resolution of a variety of mysterious properties of water and ice from the perspective of hydrogen-bond cooperativity in response to stimuli such as chemical contamination, electrification, magnetification, mechanical compression, molecular undercoordination, and thermal excitation. Anomalies include the floating of ice, the Hofmeister effect in solutions, regelation of ice, slipperiness of ice, water’s tough skin, the Mpemba paradox, and the floating bridge. It also addresses the superfluidity of microchannels, hydrogen bond potentials, nanodroplet and bubble thermodynamics, quasisolidity and supersolidity, controlling superhydrophobicity–superhydrophilicity transition, and high-pressure ice formation. The target audience for this book includes students, senior scholars, engineers and practitioners in the area of physical chemistry, biology, as well as aqueous and colloid solutions.

Book Description
The integrity of knowledge that emerges from research is based on individual and collective adherence to core values of objectivity, honesty, openness, fairness, accountability, and stewardship. Integrity in science means that the organizations in which research is conducted encourage those involved to exemplify these values in every step of the research process. Understanding the dynamics that support â€" or distort â€" practices that uphold the integrity of research by all participants ensures that the research enterprise advances knowledge. The 1992 report Responsible Science: Ensuring the Integrity of the Research Process evaluated issues related to scientific responsibility and the conduct of research. It provided a valuable service in describing and analyzing a very complicated set of issues, and has served as a crucial basis for thinking about research integrity for more than two decades. However, as experience has accumulated with various forms of research misconduct, detrimental research practices, and other forms of misconduct, as subsequent empirical research has revealed more about the nature of scientific misconduct, and because technological and social changes have altered the environment in which science is conducted, it is clear that the framework established more than two decades ago needs to be updated. Responsible Science served as a valuable benchmark to set the context for this most recent analysis and to help guide the committee's thought process. Fostering Integrity in Research identifies best practices in research and recommends practical options for discouraging and addressing research misconduct and detrimental research practices.

Book Description
This Open Access biography chronicles the life and achievements of the Norwegian engineer and physicist Rolf Widerøe. Readers who meet him in the pages of this book will wonder why he isn't better known. The first of Widerøe's many pioneering contributions in the field of accelerator physics was the betatron. He later went on to build the first radiation therapy machine, an advance that would eventually revolutionize cancer treatment. Hospitals worldwide installed his machine, and today's modern radiation treatment equipment is based on his inventions. Widerøe's story also includes a fair share of drama, particularly during World War II when both Germans and the Allies vied for his collaboration. Widerøe held leading positions in multinational industry groups and was one of the consultants for building the world's largest nuclear laboratory, CERN, in Switzerland. He gained over 200 patents, received several honorary doctorates and a number of international awards. The author, a professional writer and maker of TV documentaries, has gained access to hitherto restricted archives in several countries, which provided a wealth of new material and insights, in particular in relation to the war years. She tells here a gripping and illuminating story.

Book Description
The Newbery Award-winning author of Up a Road Slowly presents the unforgettable story of Jethro Creighton—a brave boy who comes of age during the turbulent years of the Civil War. In 1861, America is on the cusp of war, and young Jethro Creighton is just nine-years-old. His brother, Tom, and his cousin, Eb, are both of fighting age. As Jethro's family is pulled into the conflict between the North and the South, loyalties are divided, dreams are threatened, and their bonds are put to the test in this heart-wrenching, coming of age story. “Drawing from family records and from stories told by her grandfather, the author has, in an uncommonly fine narrative, created living characters and vividly reconstructed a crucial period of history.”—Booklist

Book Description
Like music, art is a universal language. Although looking at works of art is a pleasurable enough experience, to appreciate them fully requires certain skills and knowledge." --Carol Strickland, from the introduction to The Annotated Mona Lisa: A Crash Course in Art History from Prehistoric to Post-Modern * This heavily illustrated crash course in art history is revised and updated. This second edition of Carol Strickland's The Annotated Mona Lisa: A Crash Course in Art History from Prehistoric to Post-Modern offers an illustrated tutorial of prehistoric to post-modern art from cave paintings to video art installations to digital and Internet media. * Featuring succinct page-length essays, instructive sidebars, and more than 300 photographs, The Annotated Mona Lisa: A Crash Course in Art History from Prehistoric to Post-Modern takes art history out of the realm of dreary textbooks, demystifies jargon and theory, and makes art accessible-even at a cursory reading. * From Stonehenge to the Guggenheim and from Holbein to Warhol, more than 25,000 years of art is distilled into five sections covering a little more than 200 pages.
