The purpose of my book, The Tip of the Arrow, A Study in Leadership, is to share with young people of today and tomorrow the story of young people like me at age sixteen as the blueprint of the Selma Student Nonviolent Civil Rights movement, a significant impacting factor in the passage of the 1964 Civil Rights Act and the dominating influence leading to the passage of the 1965 Voting Rights Act. On February 24, 2016, during a ceremony awarding the Congressional Gold Medal at the US Capitol in Washington, DC, I beamed with personal pride upon hearing Speaker Paul Ryan's statement that Congress decided to bestow the award to the foot soldiers because their contribution to our country was so great that they deserved the highest honor in our possession, the Congressional Gold Medal. The Tip of the Arrow is our story.

A comprehensive guide to archery, with illustrations for sighting and aiming, shooting, and anchoring.

This is a new release of the original 1942 edition.

Presents new, tested experiments related to the intriguing field of physical science. The experiments are designed to promote interest in science in and out of the classroom, and to improve critical-thinking skills.

From the author of The Boy, the Boat, and the Beast comes a “richly imagined fable” (Susan Fletcher, author of Journey of the Pale Bear, a Golden Kite Honor Book) about a boy who’s grown up as the only human in an enchanted rainforest and what happens when people from the outside world discover his home. For the first twelve years of Arrow’s life, he grew up as the only human in a lush, magical rainforest that’s closed off from the rest of the world. He was raised by the Guardian Tree, the protector of the forest, which uses the earth’s magic to keep it hidden from those who have sought to exploit and kill it. But now the magic veil is deteriorating, the forest is dying, and Arrow may be the only one who can save it. Arrow never saw another human until one day, a man in a small airplane crash-lands in the forest. Then, a group of children finds their way in, escaping from their brutal, arid world where the rich live in luxurious, walled-off cities and the poor struggle for survival. The Guardian Tree urges Arrow to convince the trespassers to leave by any means necessary. Arrow is curious about these newcomers, but their arrival sets off a chain of events that leave him with a devastating choice: be accepted by his own kind or fight to save the forest that is his home.

Artifacts linked to projectile technologies traditionally have provided the foundations for time-space systematics and cultural-historic frameworks in archaeological research having to do with foragers. With the shift in archae ological research objectives to processual interpretations, projectile technolo gies continue to receive marked attention, but with an emphasis on the implications of variability in such areas as design, function, and material as they relate to the broader questions of human adaptation. The reason that this particular domain of foraging technology persists as an important focus of research, I think, comes in three parts. A projectile technology was a crucial part of most foragers' strategies for survival, it was functionally spe cific, and it generally was fabricated from durable materials likely to be detected archaeologically. Being fundamental to meat acquisition and the principal source of calo ries, projectile technologies were typically afforded greater time-investment, formal modification, and elaboration of attributes than others. Moreover, such technologies tend to display greater standardization because of con straints on size, morphology, and weight that are inherent to the delivery system. The elaboration of attributes and standardization of form gives pro jectile technologies time-and space-sensitivity that is greater than most other foraging technologies. And such sensitivity is immensely valuable in archae ological research.

This atlas presents normal imaging variations of the brain, skull, and craniocervical vasculature. Magnetic resonance (MR) imaging and computed tomography (CT) have advanced dramatically in the past 10 years, particularly in regard to new techniques and 3D imaging. One of the major problems experienced by radiologists and clinicians is the interpretation of normal variants as compared with the abnormalities that the variants mimic. Through an extensive collection of images, this book offers a spectrum of appearances for each variant with accompanying 3D imaging for confirmation; explores common artifacts on MR and CT that simulate disease; discusses each variant in terms of the relevant anatomy; and presents comparison cases for the purpose of distinguishing normal findings from abnormalities. It includes both common variants as well as newly identified variants that are visualized by recently developed techniques such as diffusion-weighted imaging and multidetector/multislice CT. The book also highlights normal imaging variants in pediatric cases. Atlas of Normal Imaging Variations of the Brain, Skull, and Craniocervical Vasculature is a valuable resource for neuroradiologists, neurologists, neurosurgeons, and radiologists in interpreting the most common and identifiable variants and using the best methods to classify them expediently.
