[tag line] critically and cleverly examines the origins, evolution, and impact of the Ninja Turtles phenomenon - from its beginning as a self-published black-and-white comic book in 1984, through its transformation into a worldwide transmedia phenomenon by the middle of the 1990s, and up to the sale of the property to Nickelodeon in 2009 and relaunch of the Turtles with new comics, cartoons, and a big-budget Hollywood film. With the eye of contemporary cultural studies and the voice of a true lifelong Turtles fan, Rosenbaum argues that the Turtles' continuing success isn't mere nostalgia, but rather the result of characters, and a franchise, that mutated in a way that allowed the to survive and thrive in a post-modern world.

Michelle Stewart always knew in her heart that her eating disorder would kill her. What she didn’t expect in its early stages was that she would continue to function - albeit far from optimally - for decades before succumbing to its deadly effects. A conscientious and ambitious woman driven by a desire to make a positive difference in the world, Michelle went on to build a successful career first in journalism and then in communications for the British Columbia Ministry of Health. Michelle devoted her working life to raising awareness of healthcare issues, all the while hiding her own anorexia and bulimia from friends and colleagues. By the time she was 48 years old, more than thirty years of self-imposed starvation, binging and purging had ravaged her organs. In May 2013 she was diagnosed with end-stage renal failure and given only a few months to live. Determined to come out of the shadows and share her story while she still had the chance, Michelle began writing a very personal and revealing blog in which she chronicled her lifelong struggle with her eating disorder and her experiences as a palliative patient within the very same healthcare system in which she had performed her life’s work. “I have had a 32 year dress rehearsal for the fate I now face,” she writes. This memoir is a collection of the most poignant pieces of writing from that blog, supplemented with previously unpublished pieces of original poetry from the author. Michelle Stewart’s book stands out against other eating disorder memoirs in several ways. As a middle aged longtime sufferer, she belies the notion that eating disorders only affect the young - or that victims tend to either recover or perish early. According to experts featured in the foreword, medical practictioners who treat patients with eating disorders are seeing rising numbers of long-term sufferers like Michelle. These tend to be high-functioning individuals who keep their disorder underground for years while their bodies slowly disintegrate. Michelle’s advanced years give her a valuable and rare perspective on a widespread mental health problem. Second, through her years spent in healthcare advocacy and communications, Michelle developed well informed insight into issues around medical services and the relationships between healthcare providers and their patients, including palliative patients. In her book, Michelle shares her personal views on disease-specific funding, patient care and the right-to-die movement, making a valuable contribution to the public conversation. Finally, the book is a deeply engaging and compelling tale of terminal illness progression that follows one woman from diagnosis to death. Anyone who has been touched by life-limiting illness in their own experience or in their family will be moved by this account of the palliative care journey told from the patient’s perspective.

The Bash Guide for Beginners (Second Edition) discusses concepts useful in the daily life of the serious Bash user. While a basic knowledge of shell usage is required, it starts with a discussion of shell building blocks and common practices. Then it presents the grep, awk and sed tools that will later be used to create more interesting examples. The second half of the course is about shell constructs such as loops, conditional tests, functions and traps, and a number of ways to make interactive scripts. All chapters come with examples and exercises that will help you become familiar with the theory.

In this “luminous” (The New York Times) historical novel—perfect for fans of All the Light We Cannot See and The Flamethrowers—a Swedish glassmaker and a fiercely independent Australian journalist are thrown together amidst the turmoil of the 1960s and the dawning of a new modern era. 1965: As the United States becomes further embroiled in the Vietnam War, the ripple effects are far-reaching—even to the other side of the world. In Australia, a national military draft has been announced and Pearl Keogh, an ambitious newspaper reporter, has put her job in jeopardy to become involved in the anti-war movement. Desperate to locate her two runaway brothers before they’re called to serve, Pearl is also hiding a secret shame—the guilt she feels for not doing more for her younger siblings after their mother’s untimely death. Newly arrived from Sweden, Axel Lindquist is set to work as a sculptor on the besieged Sydney Opera House. After a childhood in Europe, where the shadow of WWII loomed large, he seeks to reinvent himself in this foreign landscape, and finds artistic inspiration—and salvation—in the monument to modernity that is being constructed on Sydney’s Harbor. But as the nation hurtles towards yet another war, Jørn Utzon, the Opera House’s controversial architect, is nowhere to be found—and Axel fears that the past he has tried to outrun may be catching up with him. As the seas of change swirl around them, Pearl and Axel’s lives orbit each other and collide in this sweeping novel “that brings the cultural upheaval of 1960s Australia vividly to life, and readers who appreciate leisurely paced, thoughtful literary fiction will savor each word of this emotional story of two people—and a country—reckoning with their past and future” (Booklist).
