The U.S. underground coal miner faces a continuing hazard from the fall of roof. At the root of many injuries and fatalities are weak or defective roof strata. Throughout mining history, millions of miles of entry have provided exposure of every conceivable geologic roof hazard. This report describes the geologic origin, association, and potential danger from the most common hazards. Discussions of weak rock include drawrock, rider coals, head coal, stackrock, and stream valley effects. Discontinuities, or roof defects, are described including, clay veins, slickensides, joints, and paleochannels. A number of examples from U.S. coalfields are used to document geologic structure and associated hazards. Roof fall analysis is a methodology used by NIOSH for hazard recognition and prevention; its application and benefit to the industry are discussed.

Rose of the Winds: the Origin and Development of the Compass-Card
By Silvanus P. Thompson
Excerpt
Although the construction of the compass lies outside the scope of this inquiry, some preliminary considerations are necessary concerning the origin of the compass itself; and these must be stated briefly. The mariners' compass, as we know it to-day, consists of a light circular disk or card, beneath which is attached a magnetic needle or system of magnetic needles. The card is provided at its centre with a small cap, by which it is poised movably upon a pin. The whole is enclosed in a hollow box or bowl covered with a flat lid of glass; and the compass box or bowl is suspended within two hinged rings of brass to enable it to conserve its proper horizontal position in spite of any tilting movement to which it is subjected by the rolling or pitching of the ship on which it is carried.
The card is divded out into thirty-two 'points' or 'rhumbs' of equal angular breadth forming a rose or star, and to these are affixed the initials of the names of the thirty-two points. The magnet needle, or system of needles, is affixed to the card parallel to the direction marked NS on the card, so that when left to itself, the card, obeying the directive force which acts on the needle, sets itself in a direction pointing (magnetically) North and South; the several 'points' marked on the card then indicating the several directions that the mariner may know in which way to steer in order to follow his desired course. The card is also usually marked at its North point with a fleur-de-lis or other distinctive sign. The magnetic needle is controlled in its pointing by the magnetism of the earth's globe.
It is no part of the present paper to enter upon the reasons for the irregularities which are found to exist in the directive force of the earth, and which produce those local 'variations' of the compass which the mariner encounters everywhere. Neither is there here any question considered as to the errors or perturbations due to the presence near the compass of pieces of iron on the ship, nor as to those due to the incidental presence of magnetism in the iron of the ship's hull or fittings; nor, again, as to the means for compensating those perturbations or correcting those errors.
The compass, as above described, has remained practically unchanged in all essential particulars for...

Windham Press is committed to bringing the lost cultural heritage of ages past into the 21st century through high-quality reproductions of original, classic printed works at affordable prices.
This book has been carefully crafted to utilize the original images of antique books rather than error-prone OCR text. This also preserves the work of the original typesetters of these classics, unknown craftsmen who laid out the text, often by hand, of each and every page you will read. Their subtle art involving judgment and interaction with the text is in many ways superior and more human than the mechanical methods utilized today, and gave each book a unique, hand-crafted feel in its text that connected the reader organically to the art of bindery and book-making.
We think these benefits are worth the occasional imperfection resulting from the age of these books at the time of scanning, and their vintage feel provides a connection to the past that goes beyond the mere words of the text.

From 1990-1997, Drew Ross served as a forensic psychiatrist for the criminal justice system. His job was to judge the "sanity" of people charged with murder. The law requires black-and-white answers; unfortunately, Ross' training had taught him that the human mind is more complex than the law would allow.

Looking Into the Eyes of a Killer details one man's journey into the darkness of the human psyche and the evils of a system. Standing at the crossroads of psychiatry and the law, Ross explores the many contradictions and misconceptions that prevail when juries and judges evaluate insanity pleas and issues of blame. Never falling prey to easy solutions, he makes a compelling argument for new guidelines for dealing with violent criminals, and shows how our failure to "reform" them springs from our unwillingness to confront ourselves.

NEW INSIGHT INTO SHAKESPEARE'S SONNET SEQUENCE Berkeley's John Noonan presents the case for a new reading of 22 of Shakespeare's Sonnets Berkeley, California. John T. Noonan, Jr., U.C. Berkeley professor and federal judge, is the author of Shakespeare's Spiritual Sonnets just published by Amazon. Noonan presents argument and analysis of the Sonnets pointing to addressees of these poems far from the usual suspects. His candidates include God, the Virgin Mary, Mother Church, and Jesuit missionaries to England. He himself acknowledges his own reluctance to believe that the Bard was "mixed up with Jesuits." Imagine for a moment discovering new poems by Shakespeare. Noonan discards the assumption that the Sonnets reflect the course of two or more love affairs. Observing that it is generally agreed that some of the Sonnets are commissioned work urging a young man to marry, and that two sonnets are addressed to the poet's soul, he argues that each of the remaining sonnets should be examined in terms of its particular purpose and addressee. His analysis is both negative, pointing to substantial difficulties and gaps in the standard approach, and positive, showing the probability of a different reading. Not by Euclidean logic, he writes, but by a convergence of probabilities is the case made. Noonan's interpretation sets the 22 sonnets firmly in the context of religious controversy and compelled conformity in Queen Elizabeth's Britain and in the larger context of continental currents of theology. Shakespeare, Noonan notes, was a man of his time, and the time extends back to Pope Gregory's dispatch of missionaries to England a thousand years earlier. Noonan offers a spectrum within which he suggests that Shakespeare fits. At one end is William Byrd, composer for Queen Elizabeth and composer of masses and motets for the Catholic underground. At the other end of the spectrum is Robert Southwell, S.J., sought, caught, and hung as a priest criminally present in the country. Between them, Noonan places Shakespeare, who borrowed ideas and inspiration from Southwell's poems and who emulated Byrd in his ability to please the queen and to enhearten his own disfavored community. Noonan's book is likely to lead many lovers of Shakespeare to look at the Sonnets afresh.

Christian parenting is hard work--and it's getting harder. Parents have a deep desire to pass on their faith, but fear that today's increasingly skeptical and hostile world will eventually lead their kids to reject the truth of Christianity. That leaves many parents feeling overwhelmed--uncertain of what they can do to help their children, given the difficulty and extent of the faith challenges they will face. This practical and timely resource gives parents the confidence of knowing what to discuss with their children and how to discuss it in order to facilitate impactful conversations that will form the basis of a lifelong faith. In a friendly, parent-to-parent voice, Natasha Crain identifies 30 specific conversations about God that parents must have with their children, organizing them under the categories of - the existence of God - science and God - the nature of God - believing in God - the difference God makes Chapters are sequenced in a curriculum-oriented way to provide a cumulative learning experience, making this book a flexible resource for use in multiple settings: homes, church classes, youth groups, small groups, private Christian schools, and homeschools. Every chapter has a step-by-step conversation guide with discussion questions and tips, and content is readily adaptable for use with kids of any age (elementary through high school). Endorsements: "My prayer is that God will use this book to both motivate and equip you to help your kids develop convictions about their faith."--From the foreword by Sean McDowell, PhD, Biola University professor, speaker, and author of more than eighteen books, including A New Kind of Apologist "I can't think of a more relevant or more needed book for parents raising kids in today's culture. This book on apologetics will lead parents in critical conversations that will help grow and guide kids to be lifelong followers of Christ."--Kristen Welch, author of Raising Grateful Kids in an Entitled World "Hey parents: Do you want to reduce the chances that your child will follow the crowd to the point of rejecting Christ and the values and truths you hold so dearly? Then you need to have the conversations that Natasha Crain so brilliantly describes in this book. Prevent heartbreak later by reading and heeding this book now!"--Frank Turek, PhD, president of CrossExamined Ministries and author of I Don't Have Enough Faith to Be an Atheist and Stealing from God "May this book lead to thousands more Moms and Dads engaging with their kids through an intelligent faith. And may there be tens of thousands more kids who feel loved because the adults in their lives take their questions seriously."--Jeff Myers, PhD, president, Summit Ministries

Many regard jazz as the soundtrack of America, born and raised in its cities and echoing throughout its tumultuous century of progress. So when Ernest Hemingway wrote about seeing jazz in 1920s Paris, and when British colonial officials danced to jazz in the clubs of Calcutta in the waning years of the Raj, how, exactly, had it gotten there? Jazz Worlds/World Jazz aims to answer these questions and more, bringing together voices from countries as far flung as Azerbaijan, Armenia, and India to show that the story of jazz is not trapped in American history books but alive in global modernity. Monumental in scope, this book explores the relationship between jazz and culture and how they influence each other across a range of themes and settings. Contributors offer an analysis of the social meaning of jazz in Iran, a look at the genesis of Ethiopian jazz and at Indian fusion, and chapters on jazz diplomacy, Balkan swing, and that French export par excellence: Django Reinhardt. Altogether the contributors approach jazz--in these global iterations--through the themes that have always characterized it at home: place, history, mobility, media, and race. The result is a first-of-its-kind map of jazz around the globe that pays tribute to the players who have given the form its seemingly infinite possibilities.

This compact book outlines the controversies andimplications of the central debate of the Reformation: justification by faith alone.Luther said that the doctrine of justificationby faith alone is "the article upon which the church stands orfalls." R. C. Sproul follows Luther's lead in his concise andcompelling work, now repackaged and republished. Justified byFaith Alone surveys the main tenets of the doctrine ofjustification in Roman Catholicism and evangelicalism. Sproul iscareful to accurately represent Catholic beliefs and observes thatwhile both traditions agree that faith is necessary forjustification, the difference lies in whether faith alone issufficient. He explores problems with the Catholic doctrine andchampions the sole sufficiency of Christ for our salvation.Effective and engaging, Sproul does not shyaway from difficult theological terms and ideas, but capably guidesreaders through this famous doctrinal dispute. To those who decrythe doctrines of imputation and justification by faith alone as"legal fiction," Sproul warns that nothing less than the centralmessage of the gospel is at stake.

Her courage and her heart will be tested in ways she never expected...
Beth Thatcher has spent her entire life in the safe, comfortable world of her family, her friends, and the social outings her father's wealth provides. But Beth is about to leave it all behind to accept a teaching position in the rugged foothills of western Canada. Inspired by her aunt Elizabeth, who went west to teach school several years ago, and gently encouraged by her father, Beth resolves to put her trust in God and bravely face any challenge that comes her way.
But the conditions in Coal Valley are even worse than she'd feared. A recent mining accident has left the town grieving and at the mercy of the mining company. The children have had very little prior education, and many of the locals don't even speak English. There isn't even a proper schoolhouse. In addition, Beth's heart is torn between two young men--both Mounties, one a lifelong friend and the other a kind, quiet man who comes to her aid more than once.
Despite the many challenges, Beth is determined to make a difference in the rustic frontier town. But when her sister visits from the East, reminding her of all the luxuries she's had to give up, will Beth decide to return to her privileged life as soon as the school year is over?
