Mobile Communication and Greater China (Routledge Research on Social Work, Social Policy and Social Development in Greater China)
by Pui-Lam Law Leopoldina Fortunati Rodney Wai-chi Chu Shanhua YangThis edited volume is the first book-length study focusing entirely on mobile phone use in China. Drawing on examples from a wide range of contemporary situations in China and beyond, the contributors argue that the mobile phone is in fact an important means by which one can understand a rapidly changing China, and the developing culture of mobile phone usage reflects both the cultural norms and struggle of the people. Through a theoretical comparison of usage in the West and in China, the editors assert the uniqueness of China’s experience, highlighting that Chinese society is being exposed simultaneously to a rapid process of industrialization and cyberization. The contributors maintain that such density of experience under a compressed period combined with a thick cultural heritage and a country still under a dictating rule provides a unique situation and offers deep insights into Chinese culture in general. This work will be of great interest to all students and scholars of Asian communication studies, ICT and Chinese culture and society.

Mobile Cultures: New Media in Queer Asia
by Chris Berry Audrey Yue Fran MartinMobile Cultures provides much-needed, empirically grounded studies of the connections between new media technologies, the globalization of sexual cultures, and the rise of queer Asia. The availability and use of new media--fax machines, mobile phones, the Internet, electronic message boards, pagers, and global television--have grown exponentially in Asia over the past decade. This explosion of information technology has sparked a revolution, transforming lives and lifestyles, enabling the creation of communities and the expression of sexual identities in a region notorious for the regulation of both information and sexual conduct. Whether looking at the hanging of toy cartoon characters like "Hello Kitty" from mobile phones to signify queer identity in Japan or at the development of queer identities in Indonesia or Singapore, the essays collected here emphasize the enormous variance in the appeal and uses of new media from one locale to another. Scholars, artists, and activists from a range of countries, the contributors chronicle the different ways new media galvanize Asian queer communities in Taiwan, South Korea, Japan, Indonesia, Thailand, Malaysia, India, and around the world. They consider phenomena such as the uses of the Internet among gay, lesbian, or queer individuals in Taiwan and South Korea; the international popularization of Japanese queer pop culture products such as Yaoi manga; and a Thai website's reading of a scientific tract on gay genetics in light of Buddhist beliefs. Essays also explore the politically subversive possibilities opened up by the proliferation of media technologies, examining, for instance, the use of Cyberjaya--Malaysia's government-backed online portal--to form online communities in the face of strict antigay laws.

Mobile Multimedia in Action
by Ilpo Koskinen"Mobile Multimedia in Action" displays a revealing picture of how people communicate using camera phones and other mobile multimedia devices. With such devices spreading faster than practically any other new technology, questions about how these devices are being used (and abused) to capture and distribute embarrassing or raunchy images and content, and what should be done about it, are surfacing. This volume presents the first detailed study of the use of these devices. Using a variant of social science research known as ethnomethodology, Koskinen explores the kinds of images people take with camera phones and how they use sound to enhance these images. The book asks two main questions. First, what kinds of methods of expression, such as visuals or sound, do people use when they design multimedia messages? Second, how do people interact with and respond to each other through mobile multimedia devices? Koskinen has a broader objective centering on the impact of these devices on human relationships and society at large. He asks, What do people do with these devices? Is mobile telephony moving toward a more practical direction, or will it simply become a visual chatty channel fit for gossip but not for real news or other practical purposes? What kind of social activities and organizations does it best serve - peer-to-peer networks or institutional ones? Koskinen examines these questions from three unique perspectives: the design elements of mobile multimedia, which considers methods of expression people use in designing multimedia messages; mobile multimedia as interaction, which looks into how people interact with each other using this technology and makes a case for studying multimedia as a naturally occurring activity; and mobile multimedia in society, which searches for answers as to the societal consequences of mobile multimedia usage. A groundbreaking work, "Mobile Multimedia in Action" will be a fascinating read for both multimedia device professionals and everyday users alike. Providing a glimpse into the future, Koskinen asks where mobile multimedia technology is taking mankind and society.
