The disturbing truth: school suspension does more than impede Black students' academic achievement—it also impacts their parents' employment and can violate state and federal laws. Finalist of the C. Wright Mills Award by the Society for the Study of Social Problems Decades of urban disinvestment and poverty have made educational attainment for Black youth more vital than at any time in recent history. Yet in their pursuit of quality education, many Black families are burdened by challenging barriers to success, most notably the frequency and severity of school punishment. Such punishment is meant to be a disciplinary tool that makes schools safer, but it actually does the opposite—and is particularly harmful for Black students and their families. Focusing on schools in inner-city and suburban Detroit, Charles Bell draws on 160 in-depth interviews with Black high school students, their parents, and their teachers to illuminate the negative outcomes that are associated with out-of-school suspension. Bell also sheds light on the inherent shortcomings of school safety measures as he describes how schools fail to protect Black students, which leaves them vulnerable to bullying and victimization. The students he interviews offer detailed insight into how the lack of protection they received in school intensified their fear of being harmed and even motivated them to use violence to establish a reputation that discouraged attacks. Collectively, their narratives reveal how receiving a suspension for fighting in school earned them respect, popularity, and a reputation for toughness—transforming school punishment into a powerful status symbol that destabilizes classrooms. A thought-provoking and urgent work, Suspended calls for an inclusive national dialogue on school punishment and safety reform. It will leave readers engrossed in the students' and parents' tearful narratives as they share how school suspension harmed students' grades, disrupted parents' employment, violated state and federal laws, and motivated families to withdraw from punitive districts.

Maintaining and Troubleshooting Your 3D Printer helps you achieve and hold proper alignment. Maintaining and Troubleshooting Your 3D Printer also helps with software and hardware troubleshooting. You’ll learn to diagnose and solve firmware calibration problems, filament and feed problems, chassis issues, and more. Finally there are regular maintenance and enhancements. You’ve invested significantly in your 3D printer. Protect that investment using the guidance in this book. Learn to clean and lubricate your printer, to maintain the chassis, and know when realignment of the print bed is needed. Learn ways to master your craft and improve the quality of your prints through such things as post-print finishing and filament management. Don’t let the challenges of 3D printing stand in the way of creativity. Maintaining and Troubleshooting Your 3D Printer by Charles Bell helps you conquer the challenges and get the most benefit from your expensive investment in personal fabrication.

The present book is an attempt to speak about the life of the Tibetan people in their own homes. The contents are left on the author's first-hand knowledge of Tibetan life during a residence of nearly twenty years from a conversation with his Tibetan acquaintances in their own language not through interpreters. In order to keep this volume within moderate limits, he had to exclude from it many aspects of Tibetan life. Shut-off from the outer world by their immense mountain barriers Tibet still presented a virgin field of enquiry. There has been little change in the inner life of the people during the last thousand years. As the area is very large and the intercourse of one part with another is restricted, the manners and customs vary in different districts and provinces.

The book deals with Tibetan history from the earliest times, but especially with the aims and movements of the period witnessed by the author. Anecdotes, conversations with leading Tibetans, and quotations from poetry and proverbs illustrate the Tibetan point of view. Sir Charles Bell gives an inside view of the Tibetans; he served for eighteen years on the Indo-Tibetan frontier, spoke and wrote the Tibetan language, and was brought into close touch with all classes from the reigning Dalai Lama downwards. Recent developments in Tibet have attracted worldwide attention and through this Indian edition, Sir Charles Bell's classic study will perhaps be more eagerly read now than ever before.

The disturbing truth: school suspension does more than impede Black students' academic achievement—it also impacts their parents' employment and can violate state and federal laws. Decades of urban disinvestment and poverty have made educational attainment for Black youth more vital than at any time in recent history. Yet in their pursuit of quality education, many Black families are burdened by challenging barriers to success, most notably the frequency and severity of school punishment.
