Migration and New Media
How do parents and children care for each other when they are separated because of migration? The way in which transnational families maintain long-distance relationships has been revolutionised by the emergence of new media such as email, instant messaging, social networking sites, webcam and texting. A migrant mother can now call and text her left-behind children several times a day, peruse social networking sites and leave the webcam for 12 hours achieving a sense of co-presence.
Drawing on a long-term ethnographic study of prolonged separation between migrant mothers and their children who remain in the Philippines, this book develops groundbreaking theory for understanding both new media and the nature of mediated relationships. It brings together the perspectives of both the mothers and children and shows how the very nature of family relationships is changing. New media, understood as an emerging environment of polymedia, have become integral to the way family relationships are enacted and experienced. The theory of polymedia extends beyond the poignant case study and is developed as a major contribution for understanding the interconnections between digital media and interpersonal relationships.

5G for the connected world
\"After the considerable success of LTE, why do we need a new system with a new radio and a new core? First, 5G will boost some of the LTE key performance indicators to a new horizon: capacity, latency, energy efficiency, spectral efficiency and reliability. We will describe the relevant radio and core features to enable optimizations (5G to be 10, 100 or 1000 times better than LTE) in these areas in respective chapters of the book\"-- Provided by publisher.

5G for the Connected World
<p><b>COMPREHENSIVE HANDBOOK DEMYSTIFIES 5G FOR TECHNICAL AND BUSINESS PROFESSIONALS IN MOBILE TELECOMMUNICATION FIELDS</b> <p>Much is being said regarding the possibilities and capabilities of the emerging 5G technology, as the evolution towards 5G promises to transform entire industries and many aspects of our society. <i>5G for the Connected World</i> offers a comprehensive technical overview that telecommunication professionals need to understand and take advantage of these developments. <p>The book offers a wide-ranging coverage of the technical aspects of 5G (with special consideration of the 3GPP Release 15 content), how it enables new services and how it differs from LTE. This includes information on potential use cases, aspects of radio and core networks, spectrum considerations and the services primarily driving 5G development and deployment. <p>The text also looks at 5G in relation to the Internet of Things, machine to machine communication and technical enablers such as LTE-M, NB-IoT and EC-GSM. Additional chapters discuss new business models for telecommunication service providers and vertical industries as a result of introducing 5G, and strategies for staying ahead of the curve. Other topics include: <ul> <li>Key features of the new 5G radio such as descriptions of new waveforms, massive MIMO and beamforming technologies, as well as spectrum considerations for 5G radio regarding all possible bands</li> <li>Drivers, motivations and an overview of the new 5G system – especially RAN architecture and technology enablers (e.g. service-based architecture, compute-storage split and network exposure) for native cloud deployments</li> <li>Mobile edge computing, Non-3GPP access, Fixed-Mobile Convergence</li> <li>Detailed overview of mobility management, session management and Quality of Service frameworks</li> <li>5G security vision and architecture</li> <li>Ultra-low latency and high reliability use cases and enablers, challenges and requirements (e.g. remote control, industrial automation, public safety and V2X communication)</li> <li>An outline of the requirements and challenges imposed by a massive number of devices connected to cellular networks</li> </ul> <p>While some familiarity with the basics of 3GPP networks is helpful, <i>5G for the Connected World</i> is intended for a variety of readers. It will prove a useful guide for telecommunication professionals, standardization experts, network operators, application developers and business analysts (or students working in these fields) as well as infrastructure and device vendors looking to develop and integrate 5G into their products, and deploy 5G radio and core networks.

Language Online
In Language Online, David Barton and Carmen Lee investigate the impact of the online world on the study of language.
The effects of language use in the digital world can be seen in every aspect of language study, and new ways of researching the field are needed. In this book the authors look at language online from a variety of perspectives, providing a solid theoretical grounding, an outline of key concepts, and practical guidance on doing research.
Chapters cover topical issues including the relation between online language and multilingualism, identity, education and multimodality, then conclude by looking at how to carry out research into online language use. Throughout the book many examples are given, from a variety of digital platforms, and a number of different languages, including Chinese and English.
Written in a clear and accessible style, this is a vital read for anyone new to studying online language and an essential textbook for undergraduates and postgraduates working in the areas of new media, literacy and multimodality within language and linguistics courses.

Radio Protocols for LTE and LTE-Advanced
Provides a unique focus on radio protocols for LTE and LTE-Advanced (LTE-A)Giving readers a valuable understanding of LTE radio protocols, this book covers LTE (Long-Term Evolution) Layer 2/3 radio protocols as well as new features including LTE-Advanced. It is divided into two sections to differentiate between the two technologies’ characteristics. The authors systematically explain the design principles and functions of LTE radio protocols during the development of mobile handsets. The book also provides essential knowledge on the interaction between mobile networks and mobile handsets.Among the first publications based on the 3GPP R10 specifications, which introduces LTE-A Beginning with an overview of LTE, topics covered include: Idle Mode Procedure; Packet Data Convergence Protocol and Public Warning Systems Presents the LTE radio interface protocol layers in a readable manner, to enhance the material in the standards publications From an expert author team who have been directly working on the 3GPP standards It is targeted at professionals working or intending to work in the area and can also serve as supplementary reading material for students who need to know how theory on the most extensively used mobile radio interface today is put into practice

Big Data, Little Data, No Data
\"Big Data\" is on the covers of Science, Nature , the Economist , and Wired magazines, on the front pages of the Wall Street Journal and the New York Times. But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines. Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six \"provocations\" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.
