. . . rarely have inventor and invention been better served than in this book." – New York Times Book Review Here, Edwin Grosvenor, American Heritage's publisher and Bell's great-grandson, tells the dramatic story of the race to invent the telephone and how Bell's patent for it would become the most valuable ever issued. He also writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. And he examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.

As the son of a deaf mother and the husband to a deaf wife, Alexander Graham Bell was understandably interested in communication and sound. Along with a lifelong talent for inventing things, these interests fueled Bells development of the telephone. Young readers will be inspired by Bells boundless curiosity and enthusiasm for new inventions. A timeline, science facts page, and great historical photographs make this book a must for kids interested in science or history.
Navajo Infancy describes the major sources of change and continuity in Navajo infant development. It does so by combining concepts and methods of classical ethology with those of social-cultural anthropology. The goal is to establish the relationships between human nature and culture. Buy considering the nature of adaptation, and the evolution of human developmental patterns, and through analyses of the determinants of change and continuity in Navajo infant development, Navajo Infancy outlines how the process of development itself may bridge nature and culture.With its special focus on the effect of the cradleboard on Navajo mother-infant interaction, Navajo Infancy raises important developmental issues in its analyses of why the eff ects of the cradleboard do not last. Incorporating the Brazelton Neonatal Behavioral Assessment Scale into its ethological-anthropological methods, Navajo Infancy demonstrates signifi cant Navajo-Anglo-American differences in newborn temperament. It fi nds a strong correlation between newborn behavior and prenatal environmental factors, arguing that racial and ethnic differences in behavior at birth go well beyond simple gene pool differences.Navajo Infancy also describes the individual and group differences in the development of Navajo and Anglo- American children's fear of strangers and patterns of mother-infant interaction. Aspects of attachment theory, transactional theories of development, and anthropological theories of socialization are related to this broad new evolutionary approach to the process of development and nature-culture interaction.

The major cause of death in the Western world is some form of vascular disease; and principal among these forms is atherosclerotic heart disease (ASHD). Although much is known about the etiology and treatment of ASHD, there is, as yet, no specific means of prognosis of an impending coronary episode. There are, however, several indications of susceptibility to coronary disease, generally known as risk factors, the foremost of which is hyperlipidemia. Hyperlipidemia is more commonly designated as hypercholesteremia or triglyceridemia, depending upon which moiety is elevated, but since lipids are transported in the blood as members of a lipoprotein complex, the most descriptive general term would be hyperlipoproteinemia. This volume represents an effort to elucidate the origins and metabolic behavior of lipoproteins and their components, to describe aspects of the morphology, biochemistry and experimental induction of ASHD, and to describe modalities of treatment. The contributions to this book include descriptions of cholesterol synthesis and metabolism, as well as the metabolism of bile acids, the principal products of cholesterol metabolism. There are also chapters on the mechanisms of hyperlipidemia and on lipoprotein metabolism. The induction of experimental atherosclerosis and the aortic structural changes caused by this disease are discussed.
