This 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.

New in paperback: A renowned health authority reveals how we can protect ourselves against the harmful effects of electromagnetic fields. The hazards of electronic pollution may once have been the stuff of science fiction, but now we know they're all too real. And now that 5G ultra-wideband technology is here to stay, the danger is greater than ever. Dr. Joseph Mercola, one of the world's foremost authorities on alternative health, has mined the scientific literature to offer a radical new understanding of how electromagnetic fields impact your body and mind. In this eye-opening guide, now available in paperback for the first time, he reveals: What EMFs (electromagnetic fields) actually are, where you find them in your daily life, and how they affect you The toll that EMFs have been proven to take on human health--and why you've been largely kept in the dark about this threat How you can actually repair the damage done by EMFs at a cellular level Practical strategies to protect yourself and your loved ones from EMFs at home, at work, and out in the world "Dr. Mercola's groundbreaking new book on the health effects of EMFs is both a sobering tale and an effective call to action." -- Thomas Cowan, M.D., author of Vaccines, Autoimmunity, and the Changing Nature of Childhood Illness and Cancer and the New Biology of Water

Creating Theoretical Research Frameworks using Multiple Methods - Insight from ICT4D Investigations (Paperback): Sergey V.... Creating Theoretical Research Frameworks using Multiple Methods - Insight from ICT4D Investigations (Paperback)

R1,382 Discovery Miles 13 820 Ships in 12 - 17 working days

By now, it is commonly accepted that investments in information and communication technologies (ICTs) can facilitate macroeconomic growth in developed countries. Research standards in ICT for development (ICT4D) are high, and it is a basic expectation that a theoretically sound conceptual investigation should yield actionable results. An additional expectation is that an on-the-ground study conducted in each setting should add to the common body of knowledge based on theory. In other words, one is expected to make a connection between the world of concepts and the world of reality. Middle-range theories and frameworks could help connect the case studies with grand theories, by helping to create a theoretically sound and practically applicable research architecture of ICT4D. This book demonstrates how creative use of various data analysis methods (e.g., data mining [DM], data envelopment analysis [DEA], and structural equation modeling [SEM]) and conceptual frameworks (e.g., neoclassical growth accounting, chaos and complexity theories) may be utilized for inductive and deductive purposes to develop and to test, in step-by-step fashion, theoretically sound frameworks for a large subset of ICT4D research questions. Specifically, this book showcases the utilization of DM, DEA, and SEM for the following purposes: Identification of the relevant context-specific constructs (inductive application) Identification of the relationships between the constructs (inductive application) Development of a framework incorporating the constructs and relationships discovered (inductive application) Testing of the constructed framework (deductive application) The book takes a multi-theoretical perspective to economic development research. It starts with an overview of ICT4D. Next it covers such frameworks and theories as neoclassical growth accounting and the theory of complementarity, complex systems and chaos theories, and the product life cycle (PLC) theory. There are also nontechnical overviews of the DM and data analytic methods that can be used in this research. Also presented is evidence that human capital and investment capital are complementary and are reliable sources of economic growth. The book concludes with methodological frameworks to guide investment decisions and the formulation of strategic policy.

John Caudwell
R588 R481 Discovery Miles 4 810 Save R107 (18%) Ships in 9 - 15 working days

John Caudwell is one of Britain's wealthiest, most successful - and most colourful - businessmen. He was just six years old when he made a promise to himself that he would make enough money to give huge sums of it away to help his family and others who were struggling with poverty. Born in a terraced house in Stoke-on-Trent, Caudwell went from bullied child to insecure trainee engineer at a local Michelin plant to self-made billionaire, befriending Sir Elton John, Eva Longoria, Hugh Grant and Robbie Williams, who have all taken part in his charity balls to raise money for Caudwell Children. It was at a car auction in 1987, the height of Mrs Thatcher's booming Britain,that he spotted the future. A mobile phone that came in an unwieldy suitcase. Within two decades Caudwell sold his Phones 4u business for GBP1.46 billion. Love, Pain & Money retraces the inspirational journey, from the very shaky beginnings of his phone empire to owning yachts, private planes, a fleet of top flight cars, a Jacobean mansion in the Midlands and London's most expensive home (featured in a Channel 4 documentary). It's a fascinating insight into the drive, ambition, focus and vision required to become a billionaire. It is also a very British story. Caudwell is a man who - despite his vast wealth - still knows the price of a pint of milk, buys his clothes from Marks & Spencer and despite having swapped the Michelin plant for Michelin-starred restaurants and hotels, can often be found in a roadside B&B, eating home-made sandwiches after one of his many cycling expeditions. And it is more than merely a rags to riches story. It is a tale of battling endless career misfortunes and overcoming a series of personal tragedies to rise to the top. Failure, disaster and horrendous private heartbreaks are all part of this tale of a troubled child who never won the approval of his father who died when John was a teenager. Love, Pain & Money - The Making of a Billionaire is a tale of our times, full of humour, grit, lessons in business and an understanding of what it takes to succeed against all odds. John Caudwell will be donating all his profits from the book to the Caudwell Children charity.

R1,257 Discovery Miles 12 570 Ships in 12 - 17 working days

Mobile phones are widely viewed as the information and communication technology that holds the most promise for bridging global digital divides. Gendered Power and Mobile Technology uses empirical research to focus on changing intersections between technology, gender and other categories of social and cultural power difference (such as age, race, class, and ethnicity) in the use of mobile communication technologies. Asking how these intersections can inform development discourse, practice, and research, this volume seeks to rectify the lack of attention to the Global South, calling for more sensitivity to the contexts and consequences of mobile phone use. Indeed, drawing on case studies from Ecuador, Ghana, Kenya, Mexico, Peru, Tanzania, and Uganda, this book engages with the intersectionality paradigm to tease out the complexities of using mobile technologies for development purposes. Gendered Power and Mobile Technology will appeal to students and researchers interested in fields such as media studies, development studies, gender and technology, feminist technoscience, anthropology, and sociology.

In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

Session Initiation Protocol (SIP), standardized by the Internet Engineering Task Force (IETF), has emulated the simplicity of the protocol architecture of hypertext transfer protocol (HTTP) and is being popularized for VoIP over the Internet because of the ease with which it can be meshed with web services. However, it is difficult to know exactly how many requests for comments (RFCs) have been published over the last two decades in regards to SIP or how those RFCs are interrelated. Handbook on Session Initiation Protocol: Networked Multimedia Communications for IP Telephony solves that problem. It is the first book to put together all SIP-related RFCs, with their mandatory and optional texts, in a chronological and systematic way so that it can be used as a single super-SIP RFC with an almost one-to-one integrity from beginning to end, allowing you to see the big picture of SIP for the basic SIP functionalities. It is a book that network designers, software developers, product manufacturers, implementers, interoperability testers, professionals, professors, and researchers will find to be very useful. The text of each RFC from the IETF has been reviewed by all members of a given working group made up of world-renowned experts, and a rough consensus made on which parts of the drafts need to be mandatory and optional, including whether an RFC needs to be Standards Track, Informational, or Experimental. Texts, ABNF syntaxes, figures, tables, and references are included in their original form. All RFCs, along with their authors, are provided as references. The book is organized into twenty chapters based on the major functionalities, features, and capabilities of SIP.

As an example of convergence, the mobile phone-especially in the form of smartphone-is now ushering in new promises of seamlessness between engagement with technology and everyday common experiences. This seamlessness is not only about how one transitions between the worlds of the device and the physical environment but it also captures the transition and convergences between devices as well (i.e. laptop to smartphone, smartphone to tablet). This volume argues, however, that these transitions are far from seamless. We see divisions between online and offline, virtual and actual, here and there, taking on different cartographies, emergent forms of seams. It is these seams that this volume acknowledges, challenges and explores-socially, culturally, technologically and historically-as we move to a deeper understanding of the role and impact of mobile communication's saturation throughout the world.
