  • The Digital Economy

    John Wiley and Sons Ltd The Digital Economy

    1 in stock

    Book SynopsisBoasting trillion-dollar companies, the digital economy profits from our emotions, our relationships with each other, and the ways we interact with the world. In this timely book, Tim Jordan deftly explores the workings of the digital economy. He discusses the hype and significance surrounding its activities and practices in order to outline important concepts, theory, and policy questions. Through a variety of in-depth case studies, he examines the areas of search, social media, service providers, free economic activity, and digital gaming. Companies discussed include Google, Baidu, Uber, Bitcoin, Wikipedia, Fortnight, and World of Warcraft. Jordan argues that the digital economy is not concerned primarily with selling products, but relies instead on creating communities that can be read by software and algorithms. Profit is then extracted through targeted advertising, subscriptions, misleading 'purchases', and service relations. The Digital Economy is an important reference for students and scholars getting to grips with this enormous contemporary phenomenon.Trade Review"A lively excursion across the varied terrains of the 'digital economy', in which the author argues that it’s not platform technologies that drive our digital searching, working, socialising and gaming, but our deep embeddedness in shared social practices, habits and collective communities."Mark Banks, University of Leicester "Writing in a personal and lively style, Tim Jordan intelligently explores the digital economic practices that constitute search, social media, online gaming and more. Tracing the perspectives, tactics and activities of users, advertisers and platforms, he separates the hype from the reality."Thomas Poell, University of Amsterdam“a welcome addition that STS scholars may find useful for future research projects conceptualising the remaking of property regimes.”LSE Review of BooksTable of ContentsAcknowledgements 1 Introduction: The Meaning of the Digital Economy 2 Search 3 Social Media 4 Taxis, Hotels and Blockchains 5 Free Online Economies 6 Online Games 7 Profit, Labour, Production and Consumption 8 Defining the Digital Economy 9 Policy 10 Conclusion References Index

  • Sex Robots, The End of Love

    Polity Press Sex Robots, The End of Love

    1 in stock

    Book SynopsisThere are more ways of connecting and communicating via technology than ever before. Yet loneliness is on the rise as we begin to experience an 'attachment crisis' in forming and maintaining intimate relationships. Enter sex robots. Built from the bodies of sex dolls, they are created to help humans – particularly men – cope with our inability to connect. In this bold and trenchant critique, Kathleen Richardson explores important questions surrounding this emerging technology. What does the rise of sex robots tell us about the way that women and girls are imagined? To what extent are porn, prostitution and child sexual exploitation driving the attachment crisis? The author argues that sex robots are produced within a framework of 'property relations' – in which egocentric Man (and his disconnection from Woman) shapes the building of robots and AI. Can this tide of destruction and disconnection be turned, and what would a revolution for the love of humanity look like? Presenting a passionate case for the abolition of practices that cast women as property, Sex Robots: The End of Love is essential reading for students and scholars of robot ethics, anthropology, gender studies, philosophy of technology, sociology and related fields, as well as anyone concerned for the future of human relationships.

    Rebel Girls Inc Ada Lovelace Cracks the Code

    1 in stock

    Book SynopsisFrom the world of Good Night Stories for Rebel Girls comes a story based on the exciting real-life adventures of Ada Lovelace, one of the world's first computer programmers.Growing up in nineteenth century London, England, Ada is curious about absolutely everything. She is obsessed with machines and with creatures that fly. She even designs her own flying laboratory!According to her mother, Ada is a bit too wild, so she encourages Ada to study math. At first Ada thinks: Bleh! Who can get excited about a subject without pictures? But she soon falls in love with it. One day she encounters a mysterious machine, and from that moment forward Ada imagines a future full of possibility-one that will eventually inspire the digital age nearly two hundred years later.Ada Lovelace Cracks the Code is the story of a pioneer in the computer sciences, and a testament to women's invaluable contributions to STEM throughout history.This historical fiction chapter book also includes additional text on Ada Lovelace's lasting legacy, as well as educational activities designed to teach simple coding and mathematical concepts.About the Rebel Girls Chapter Book SeriesMeet extraordinary real-life heroines in the Good Night Stories for Rebel Girls chapter book series! Introducing stories based on the lives and times of extraordinary women in global history, each stunningly designed chapter book features beautiful illustrations from a female artist as well as bonus activities in the backmatter to encourage kids to explore the various fields in which each of these women thrived. The perfect gift to inspire any young reader!Trade Review"Filled with examples of creativity sparked by small observations, this detailed look at the earliest days of modern computing is engaging, informative, and inspiring." ― Common Sense Media"Activities at the back of the book make [this] great to spark inspiration in girls and boys." ― Metro ParentTable of ContentsENGAGED COMMUNITY - Thanks to a supportive and active global community, Good Night Stories for Rebel Girls broke crowdfunding records. Volume 2 followed in 2017 and broke the record set by volume 1, making the series the highest funded publishing project in crowdfunding history. Since publication, the books have sold over 4 million copies and they have been translated into over 47 languages and are available worldwide. The Rebel Girls community counts on us to tell stories that help every girl in the world dream bigger, aim higher, and fight harder. STEM-ESTEEM - Most people who turn out to be scientists or engineers or mathematicians, first showed interest in those fields in elementary school. In fact, research shows that girls will not study or enter a career in STEM if they do not cultivate interests by age seven. It's incredibly rare to encounter female pioneers in the STEM space. Ada Lovelace is an excellent example of a role model whose ideas are approachable enough for a child to comprehend, and big enough to inspire. EDUCATIONAL ACTIVITIES - The book will include exercises and challenges for the young reader to learn the fundamental rules of coding. FULL-COLOR ILLUSTRATION - Unlike most chapter books for this age range, this title will incorporate at least ten full-color illustrations by Marina Muun. They will depict Ada at all ages, Victorian England, the mechanisms of the infamous difference machine, as well as Ada's incredible handwriting.

  • Nonlinear Optics on Ferroic Materials

    Wiley-VCH Verlag GmbH Nonlinear Optics on Ferroic Materials

    1 in stock

    Book SynopsisNonlinear Optics on Ferroic Materials Covering the fruitful combination of nonlinear optics and ferroic materials! The use of nonlinear optics for the study of ferroics, that is, magnetically, electrically or otherwise spontaneously ordered and switchable materials has witnessed a remarkable development since its inception with the invention of the laser in the 1960s. This book on Nonlinear Optics on Ferroic Materials reviews and advances an overarching concept of ferroic order and its exploration by nonlinear-optical methods. In doing so, it brings together three fields of physics: symmetry, ferroic order, and nonlinear laser spectroscopy. It begins by introducing the fundamentals for each of these fields. The book then discusses how nonlinear optical studies help to reveal properties of ferroic materials that are often inaccessible with other methods. In this, consequent use is made of the unique degrees of freedom inherent to optical experiments. An excursion into the theoretical foundations of nonlinear optical processes in ferroics rounds off the discussion. The final part of the book explores classes of ferroic materials of primary interest. In particular, this covers multiferroics with magnetoelectric correlations and oxide-electronic heterostructures. An outlook towards materials exhibiting novel forms of ferroic states or correlated arrangements beyond ferroic order and the study these systems by nonlinear optics concludes the work. The book is aimed equally at experienced scientists and young researchers at the interface between condensed-matter physics and optics and with a taste for bold, innovative ideas.Table of

    Book SynopsisHow do the communication practices of governments, NGOs and social movements enhance opportunities for citizen-led change? In this incisive book, Thomas Tufte makes a call for a fundamental rethinking of what it takes to enable citizens' voices, participation and power in processes of social change. Drawing on examples ranging from the Indignados movement in Spain to media activists in Brazil, from rural community workers in Malawi to UNICEF's global outreach programmes, he presents cutting-edge debates about the role of media and communication in enhancing social change. He offers both new and contested ideas of approaching social change from below, and highlights the need for institutions governments and civil society organizations alike to be in sync with their constituencies. Communication and Social Changeprovides essential insights to students and scholars of media and communications, as well as anyone concerned with the practices and processes that leadTrade Review"Tufte brings the significance of social change to life with eclectic and compelling illustrations across global contexts. This will be a classic text in conversations considering the importance of communication and the role of citizens in strategic social change. It is time for the field of communication for social change to take seriously the connections suggested in this book toward a more comprehensive framework. The attention here to social movements and political protests offers a welcome contribution to our scholarship and our practice."Karin Gwinn Wilkins, University of Texas at Austin "The ever-relevant Tufte has reinvented himself. With sensitivity he has crafted a coruscating and masterly book. The tight post-disciplinary synthesis solidifies the claim that communication study has such a key role in the reinvention of the humanities. Anyone interested in communication, humanity, democracy and change must read this book!"Colin Tinei Chasi, University of Johannesburg"[Tufte's] book is one that deserves to be used as a textbook in the field as well as a refresher on existing ideas and perspectives."European Journal of CommunicationTable of ContentsContents Foreword (Silvio Waisbord) Preface and Acknowledgements 1.

    Book SynopsisThis book offers a comprehensive overview of recently developed methods for assessing and optimizing system reliability. It consists of two main parts, for treating assessment methods and optimization methods, respectively. The first part covers methods of multi-state system reliability modelling and evaluation, Markov processes, Monte Carlo simulation and uncertainty analysis. The methods considered range from piecewise-deterministic Markov processes to belief function analysis. The second part covers optimization methods of mathematical programming and evolutionary algorithms, and problems of multi-objective optimization and optimization under uncertainty. The methods of this part range from non-dominated sorting genetic algorithm to robust optimization. The book also includes the application of the assessment and optimization methods considered on real case studies, particularly with respect to the reliability assessment and optimization of renewable energy systems,Table of ContentsSeries Editor’s Foreword by Dr. Andre V.
