Digitalization, Technology and Global Business: How Technology is Shaping Value Creation Across Borders
by Gaston Fornes Maria AltamiraThis book explores the impact that changes brought by digitalization are having in the way global businesses are run and grown. The main changes in recent years have come from the ubiquitous presence of technology in our daily life (and therefore in business) and also by the direction globalization is taken. Consequently, companies need to review their sources of growth.This book has four primary missions. The first is to critically analyze the impact of digitalization and technology on incumbent international business theories. The second is to deeply understand how digitalization and technology can continue to create growth opportunities. The third is to engage with the opportunities and challenges that digital models and new technologies, digital platforms and Artificial Intelligence in particular, are bringing to the current business and economic environment. And finally, the fourth is to think on possible scenarios and trends that can be the source of growth in the future. This book will be of interest to academics of digital business, international business and innovation and society. It will also be of interest to practitioners and policymakers.
Digitalization: Contexts, Roles, and Outcomes
by Sergey V. SamoilenkoConceptually, as well as practically, digitalization is similar to the implementation of a modern computation model – the model may be a centralized setup using a mainframe or it may be extended to an N-tier architecture. Regardless of the specifics of the implementation, however, the conceptual model of data processing remains the same. Digitalization is nothing but a system relying on digital technologies to create, conduct and, potentially, expand a business activity of some sort. Digitalization can be used to create an e-commerce model for a small business or to create a global supply and distribution chain geared toward almost any kind of a business. It could also be used for non-profit purposes, such as on-line education and telemedicine or e-government. Digitalization: Contexts, Roles, and Outcomes is a contemplation and analysis of the socio-technical system that is known as digitalization. It considers the context of digitalization as well as the ways by which digitalization offers value to the context within which it operates. This book aims to offer readers an entry point to a path of inquiry into the different aspects of digitalization. The goal is to identify main directions for further inquiry as well as to outline the most obvious obstacles along the way. The book aims to guide readers on their own unique journeys using the basic ideas, principles, and concepts synthesized, developed, and presented in the book. It is beneficial to both practitioners and researchers. The book covers: The functionality of digitalization The significance of digitalization Identifying the context of digitalization Designing a control system A cognitive model for the theory of digitalization Designing a theory of digitalization The book helps readers to consider the subject of digitalization in a rigorous and rational way so their own perspectives can emerge stronger and be substantiated and reinforced by building an argument vis-à-vis perspectives and points examined in this book.
Digitalized and Harmonized Industrial Production Systems: The PERFoRM Approach
by Armando Walter Colombo Michael Gepp José Barata Paulo Leitao José Barbosa Jeffrey WermannOn the one side, Industrial competitiveness today means shorter product lifecycles, increased product variety, and shorter times to market and customized tangible products and services. To face these challenges, the manufacturing industry is forced to move from traditional management, control, and automation approaches towards industrial cyber-physical systems. On the other side, several emergent engineering approaches and related Information‐Communication‐Control‐Technologies, such as Multi‐Agent-Systems, Service‐Oriented Architecture, Plug‐and‐Produce Systems, Cloud and Fog Technologies, Big Data and Analytics, among others, have been researched during the last years. The confluence of those results with the latest developments in Industrial Digitalization, Systems‐of‐Cyber-Physical-Systems Engineering, Internet‐of‐Things, Internet‐of‐Services, and Industry 4.0 is opening a new broad spectrum of innovation possibilities. The PERFoRM (Production-harmonizEd-Reconfiguration of Flexible Robots and Machinery) approach is one of them. It teaches the reader what it means when production machines and systems are digitalized and migrated into Industrial Cyber-Physical Systems and what happens when they are networked and start collaborating with each other and with the human, using the internet. After a Technology Trend Screening and beyond a comprehensive state-of-the-art analysis about Industrial Digitalization and Industry 4.0-compliant solutions, the book introduces methods, architectures, and technologies applicable in real industrial use cases, explained for a broad audience of researchers, practitioners, and industrialists.
Digitalizing Consumption: How devices shape consumer culture (Routledge Interpretive Marketing Research)
by Franck Cochoy Johan Hagberg Magdalena Petersson McIntyre Niklas SörumContemporary consumer society is increasingly saturated by digital technology, and the devices that deliver this are increasingly transforming consumption patterns. Social media, smartphones, mobile apps and digital retailing merge with traditional consumption spheres, supported by digital devices which further encourage consumers to communicate and influence other consumers to consume. Through a wide range of empirical studies which analyse the impact of digital devices, this volume explores the digitization of consumption and shows how consumer culture and consumption practices are fundamentally intertwined and mediated by digital devices. Exploring the development of new consumer cultures, leading international scholars from sociology, marketing and ethnology examine the effects on practices of consumption and marketing, through topics including big data, digital traces, streaming services, wearables, and social media’s impact on ethical consumption. Digitalizing Consumption makes an important contribution to practice-based approaches to consumption, particularly the use of market devices in consumers’ everyday consumer life, and will be of interest to scholars of marketing, cultural studies, consumer research, organization and management.

Digitally Enabled Social Change: Activism in the Internet Age
by Jennifer Earl Katrina KimportAn investigation into how specific Web technologies can change the dynamics of organizing and participating in political and social protest. Much attention has been paid in recent years to the emergence of "Internet activism," but scholars and pundits disagree about whether online political activity is different in kind from more traditional forms of activism. Does the global reach and blazing speed of the Internet affect the essential character or dynamics of online political protest? In Digitally Enabled Social Change, Jennifer Earl and Katrina Kimport examine key characteristics of web activism and investigate their impacts on organizing and participation. Earl and Kimport argue that the web offers two key affordances relevant to activism: sharply reduced costs for creating, organizing, and participating in protest; and the decreased need for activists to be physically together in order to act together. Drawing on evidence from samples of online petitions, boycotts, and letter-writing and e-mailing campaigns, Earl and Kimport show that the more these affordances are leveraged, the more transformative the changes to organizing and participating in protest.

Digitising Command and Control: A Human Factors and Ergonomics Analysis of Mission Planning and Battlespace Management (Human Factors in Defence)
by Daniel P. Jenkins Neville A. Stanton Guy H. Walker Paul M. Salmon Kirsten M. Revell Laura A. RaffertyThis book presents a human factors and ergonomics evaluation of a digital Mission Planning and Battle-space Management (MP/BM) system. An emphasis was placed on the activities at the Brigade (Bde) and the Battle Group (BG) headquarters (HQ) levels. The analysts distributed their time evenly between these two locations. The human factors team from Brunel University, as part of the HFI DTC, undertook a multi-faceted approach to the investigation, including: - observation of people using the traditional analogue MP/BM processes in the course of their work - cognitive work analysis of the digital MP/BM system - analysis of the tasks and goal structure required by the digital MP/BM - assessment against a usability questionnaire - analysis of the distributed situation awareness - an environmental survey. The book concludes with a summary of the research project's findings and offers many valuable insights. For example, the recommendations for short-term improvements in the current generation of digital MP/BM system address general design improvements, user-interface design improvements, hardware improvements, infrastructure improvements and support improvements. In looking forward to the next generation digital MP/BM systems, general human factors design principles are presented and human factors issues in digitising mission planning are considered.

Digitising the Industry Internet of Things Connecting the Physical, Digital and VirtualWorlds
by Ovidiu Vermesan Peter FriessThis book provides an overview of the current Internet of Things (IoT) landscape, ranging from the research, innovation and development priorities to enabling technologies in a global context. A successful deployment of IoT technologies requires integration on all layers, be it cognitive and semantic aspects, middleware components, services, edge devices/machines and infrastructures. It is intended to be a standalone book in a series that covers the Internet of Things activities of the IERC - Internet of Things European Research Cluster from research to technological innovation, validation and deployment. The book builds on the ideas put forward by the European Research Cluster and the IoT European Platform Initiative (IoT-EPI) and presents global views and state of the art results on the challenges facing the research, innovation, development and deployment of IoT in the next years. The IoT is bridging the physical world with virtual world and requires sound information processing capabilities for the "digital shadows" of these real things. The research and innovation in nanoelectronics, semiconductor, sensors/actuators, communication, analytics technologies, cyber-physical systems, software, swarm intelligent and deep learning systems are essential for the successful deployment of IoT applications. The emergence of IoT platforms with multiple functionalities enables rapid development and lower costs by offering standardised components that can be shared across multiple solutions in many industry verticals. The IoT applications will gradually move from vertical, single purpose solutions to multi-purpose and collaborative applications interacting across industry verticals, organisations and people, being one of the essential paradigms of the digital economy. Many of those applications still have to be identified and involvement of end-users including the creative sector in this innovation is crucial. The IoT applications and deployments as integrated building blocks of the new digital economy are part of the accompanying IoT policy framework to address issues of horizontal nature and common interest (i.e. privacy, end-to-end security, user acceptance, societal, ethical aspects and legal issues) for providing trusted IoT solutions in a coordinated and consolidated manner across the IoT activities and pilots. In this, context IoT ecosystems offer solutions beyond a platform and solve important technical challenges in the different verticals and across verticals. These IoT technology ecosystems are instrumental for the deployment of large pilots and can easily be connected to or build upon the core IoT solutions for different applications in order to expand the system of use and allow new and even unanticipated IoT end uses. Technical topics discussed in the book include: • Introduction• Digitising industry and IoT as key enabler in the new era of Digital Economy• IoT Strategic Research and Innovation Agenda• IoT in the digital industrial context: Digital Single Market• Integration of heterogeneous systems and bridging the virtual, digital and physical worlds• Federated IoT platforms and interoperability• Evolution from intelligent devices to connected systems of systems by adding new layers of cognitive behaviour, artificial intelligence and user interfaces.• Innovation through IoT ecosystems• Trust-based IoT end-to-end security, privacy framework• User acceptance, societal, ethical aspects and legal issues• Internet of Things Applications

Digitize and Punish: Racial Criminalization in the Digital Age
by Brian JeffersonTracing the rise of digital computing in policing and punishment and its harmful impact on criminalized communities of color The U.S. Bureau of Justice Statistics estimates that law enforcement agencies have access to more than 100 million names stored in criminal history databases. In some cities, 80 percent of the black male population is registered in these databases. Digitize and Punish explores the long history of digital computing and criminal justice, revealing how big tech, computer scientists, university researchers, and state actors have digitized carceral governance over the past forty years—with devastating impact on poor communities of color.Providing a comprehensive study of the use of digital technology in American criminal justice, Brian Jefferson shows how the technology has expanded the wars on crime and drugs, enabling our current state of mass incarceration and further entrenching the nation&’s racialized policing and punishment. After examining how the criminal justice system conceptualized the benefits of computers to surveil criminalized populations, Jefferson focuses on New York City and Chicago to provide a grounded account of the deployment of digital computing in urban police departments.By highlighting the intersection of policing and punishment with big data and web technology—resulting in the development of the criminal justice system&’s latest tool, crime data centers—Digitize and Punish makes clear the extent to which digital technologies have transformed and intensified the nature of carceral power.

Digitized Lives: Culture, Power, and Social Change in the Internet Era
by T. V. ReedIn a remarkably short period of time the Internet and associated digital communication technologies have deeply changed the way millions of people around the globe live their lives. But what is the nature of that impact? In chapters examining a broad range of issues—including sexuality, politics, education, race, gender relations, the environment, and social protest movements—Digitized Lives seeks answers to these central questions: What is truly new about so-called "new media," and what is just hype? How have our lives been made better or worse by digital communication technologies? In what ways can these devices and practices contribute to a richer cultural landscape and a more sustainable society? Cutting through the vast—and often contradictory—literature on these topics, Reed avoids both techno-hype and techno-pessimism, offering instead succinct, witty and insightful discussions of how digital communication is impacting our lives and reshaping the major social issues of our era. The book argues that making sense of digitized culture means looking past the glossy surface of techno gear to ask deeper questions about how we can utilize technology to create a more socially, politically, and economically just world.

Digitizing Race: Visual Cultures of the Internet (Electronic Mediations #23)
by Lisa NakamuraIn the nineties, neoliberalism simultaneously provided the context for the Internet&’s rapid uptake in the United States and discouraged public conversations about racial politics. At the same time many scholars lauded the widespread use of text-driven interfaces as a solution to the problem of racial intolerance. Today&’s online world is witnessing text-driven interfaces such as e-mail and instant messaging giving way to far more visually intensive and commercially driven media forms that not only reveal but showcase people&’s racial, ethnic, and gender identity. Lisa Nakamura, a leading scholar in the examination of race in digital media, uses case studies of popular yet rarely examined uses of the Internet such as pregnancy Web sites, instant messaging, and online petitions and quizzes to look at the emergence of race-, ethnic-, and gender-identified visual cultures. While popular media such as Hollywood cinema continue to depict nonwhite nonmales as passive audiences or consumers of digital media rather than as producers, Nakamura argues the contrary—with examples ranging from Jennifer Lopez music videos; films including the Matrix trilogy, Gattaca, and Minority Report; and online joke sites—that users of color and women use the Internet to vigorously articulate their own types of virtual community, avatar bodies, and racial politics. Lisa Nakamura is associate professor of speech communication and Asian American studies at the University of Illinois, Urbana-Champaign. She is the author of Cybertypes: Race, Ethnicity, and Identity on the Internet and coeditor, with Beth Kolko and Gilbert Rodman, of Race in Cyberspace.

Dimension-based Quality Modeling of Transmitted Speech
by Marcel WältermannIn this book, speech transmission quality is modeled on the basis of perceptual dimensions. The author identifies those dimensions that are relevant for today's public-switched and packet-based telecommunication systems, regarding the complete transmission path from the mouth of the speaker to the ear of the listener. Both narrowband (300-3400 Hz) as well as wideband (50-7000 Hz) speech transmission is taken into account. A new analytical assessment method is presented that allows the dimensions to be rated by non-expert listeners in a direct way. Due to the efficiency of the test method, a relatively large number of stimuli can be assessed in auditory tests. The test method is applied in two auditory experiments. The book gives the evidence that this test method provides meaningful and reliable results. The resulting dimension scores together with respective overall quality ratings form the basis for a new parametric model for the quality estimation of transmitted speech based on the perceptual dimensions. In a two-step model approach, instrumental dimension models estimate dimension impairment factors in a first step. The resulting dimension estimates are combined by a Euclidean integration function in a second step in order to provide an estimate of the total impairment.
