Download or read book Social Media in Industrial China written by Xinyuan Wang and published by UCL Press. This book was released on 2016-09-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life outside the mobile phone is unbearable.’ Lily, 19, factory worker. Described as the biggest migration in human history, an estimated 250 million Chinese people have left their villages in recent decades to live and work in urban areas. Xinyuan Wang spent 15 months living among a community of these migrants in a small factory town in southeast China to track their use of social media. It was here she witnessed a second migration taking place: a movement from offline to online. As Wang argues, this is not simply a convenient analogy but represents the convergence of two phenomena as profound and consequential as each other, where the online world now provides a home for the migrant workers who feel otherwise ‘homeless’. Wang’s fascinating study explores the full range of preconceptions commonly held about Chinese people – their relationship with education, with family, with politics, with ‘home’ – and argues why, for this vast population, it is time to reassess what we think we know about contemporary China and the evolving role of social media.
Download or read book The Story of Crass written by George Berger and published by . This book was released on 2009 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-depth interviews with the main movers in the punk rock movement--Crass members Penny Rimbaud, Gee Vaucher, and Steve Ignorant--detail the face of the revolution founded by these radical thinkers and artists. When punk ruled the waves, Crass waived the rules by putting out their own records, films, and magazines and setting up a series of situationist pranks that were dutifully covered by the world's press. Not just another iconoclastic band, Crass was a musical, social, and political phenomenon: commune dwellers that were rarely photographed and remained contemptuous of conventional pop stardom. As detailed in this history, their members explored and finally exhausted the possibilities of punk-led anarchy. This definitive biography of the band not only gives backstage access to their lives, philosophies, and the movement that followed, but also to never-before-seen photographs and rare dialogues.

Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

Download or read book Metamorphoses written by Emanuele Coccia and published by John Wiley & Sons. This book was released on 2021-06-09 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are all fascinated by the mystery of metamorphosis – of the caterpillar that transforms itself into a butterfly. Their bodies have almost nothing in common. They don’t share the same world: one crawls on the ground and the other flutters its wings in the air. And yet they are one and the same life. Emanuele Coccia argues that metamorphosis – the phenomenon that allows the same life to subsist in disparate bodies – is the relationship that binds all species together and unites the living with the non-living. Bacteria, viruses, fungi, plants, animals: they are all one and the same life. Each species, including the human species, is the metamorphosis of all those that preceded it – the same life, cobbling together a new body and a new form in order to exist differently. And there is no opposition between the living and the non-living: life is always the reincarnation of the non-living, a carnival of the telluric substance of a planet – the Earth – that continually draws new faces and new ways of being out of even the smallest particle of its disparate body. By highlighting what joins humans together with other forms of life, Coccia’s brilliant reflection on metamorphosis encourages us to abandon our view of the human species as static and independent and to recognize instead that we are part of a much larger and interconnected form of life.

Available in PDF, EPUB and Kindle. Book excerpt: Kim Halskov Madsen Up until a few decades ago, business administration and science were the primary areas in which computers were applied, but terms like pervasive computing reflect that interactive computing power is becoming an embedded part of people's every day environment, not only office buildings and private homes but also art and cul At one of the frontiers of multimedia applications computers are used as tural events. part of experimental theatre, puppet theatre, musical performances, museums, entertainment, and learning. In some of these domains, people interact with the computers using a mouse, keyboard and a 17-inch monitor, but present-day inter faces take a variety of forms, including motion-capture technology and displays of up to several metres in height and width. The trend of applying computer technologies in the domain of art and culture has been one of the pivots of a Danish research project, Staging of Virtual Inhabited 3D Spaces. The results of the project are presented in a series of four volumes, of which this book is the last one. The three other publications are: Virtual Interaction: Interaction in Virtual Inhabited 3D Worlds; Virtual Space: The Spatiality of Virtual Inhabited 3D Worlds; and 3D Applications: Applications with Virtual Inhabited 3D Worlds.
Download or read book Drawing the Line written by Tom Sito and published by University Press of Kentucky. This book was released on 2006-10-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the most beloved characters in film and television inhabit two-dimensional worlds that spring from the fertile imaginations of talented animators. The movements, characterizations, and settings in the best animated films are as vivid as any live action film, and sometimes seem more alive than life itself. In this case, Hollywood's marketing slogans are fitting; animated stories are frequently magical, leaving memories of happy endings in young and old alike. However, the fantasy lands animators create bear little resemblance to the conditions under which these artists work. Anonymous animators routinely toiled in dark, cramped working environments for long hours and low pay, especially at the emergence of the art form early in the twentieth century. In Drawing the Line, veteran animator Tom Sito chronicles the efforts of generations of working men and women artists who have struggled to create a stable standard of living that is as secure as the worlds their characters inhabit. The former president of America's largest animation union, Sito offers a unique insider's account of animators' struggles with legendary studio kingpins such as Jack Warner and Walt Disney, and their more recent battles with Michael Eisner and other Hollywood players. Based on numerous archival documents, personal interviews, and his own experiences, Sito's history of animation unions is both carefully analytical and deeply personal. Drawing the Line stands as a vital corrective to this field of Hollywood history and is an important look at the animation industry's past, present, and future. Like most elements of the modern commercial media system, animation is rapidly being changed by the forces of globalization and technological innovation. Yet even as pixels replace pencils and bytes replace paints, the working relationship between employer and employee essentially remains the same. In Drawing the Line, Sito challenges the next wave of animators to heed the lessons of their predecessors by organizing and acting collectively to fight against the enormous pressures of the marketplace for their class interests -- and for the betterment of their art form.

Download or read book Cartoon Modern written by Amid Amidi and published by Chronicle Books. This book was released on 2006-08-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between the classic films of Walt Disney in the 1940s and the televised cartoon revolution of the 1960s was a critical period in the history of animation. Amid Amidi, of the influential Animation Blast magazine and CartoonBrew blog, charts the evolution of the modern style in animation, which largely discarded the "lifelike" aesthetic for a more graphic and often abstract approach. Abundantly found in commercials, industrial and educational films, fair and expo infotainment, and more, this quickly popular cartoon modernism shared much with the painting and graphic design movements of the era. Showcasing hundreds of rare and forgotten sketches, model boards, cels, and film stills, Cartoon Modern is a thoroughly researched, eye-popping, and delightful account of a vital decade of animation design.
