André Caron and Letizia Caronia look at teenagers' use of text messaging to chat, flirt, and gossip. They find that messaging among teens has little to do with sending shorthand information quickly. ...Instead, it is a verbal performance through which young people create culture. Moving Cultures argues that teenagers have domesticated and reinterpreted this technology.

The open access book covers a large class of nonlinear systems with many practical engineering applications. The approach is based on the extension of linear systems theory using the Volterra series. ...In contrast to the few existing treatments, our approach highlights the algebraic structure underlying such systems and is based on Schwartz’s distributions (rather than functions). The use of distributions leads naturally to the convolution algebras of linear time-invariant systems and the ones suitable for weakly nonlinear systems emerge as simple extensions to higher order distributions, without having to resort to ad hoc operators. The result is a much-simplified notation, free of multiple integrals, a conceptual simplification, and the ability to solve the associated nonlinear differential equations in a purely algebraic way. The representation based on distributions not only becomes manifestly power series alike, but it includes power series as the description of the subclass of memory-less, time-invariant, weakly nonlinear systems. With this connection, many results from the theory of power series can be extended to the larger class of weakly nonlinear systems with memory. As a specific application, the theory is specialised to weakly nonlinear electric networks. The authors show how they can be described by a set of linear equivalent circuits which can be manipulated in the usual way. The authors include many real-world examples that occur in the design of RF and mmW analogue integrated circuits for telecommunications. The examples show how the theory can elucidate many nonlinear phenomena and suggest solutions that an approach entirely based on numerical simulations can hardly suggest. The theory is extended to weakly nonlinear time-varying systems, and the authors show examples of how time-varying electric networks allow implementing functions unfeasible with time-invariant ones. The book is primarily intended for engineering students in upper semesters and in particular for electrical engineers. Practising engineers wanting to deepen their understanding of nonlinear systems should also find it useful. The book also serves as an introduction to distributions for undergraduate students of mathematics.
This open access book offers comprehensive, self-contained knowledge on Digital Twin (DT), which is a very promising technology for achieving digital intelligence in the next-generation wireless ...communications and computing networks. DT is a key technology to connect physical systems and digital spaces in Metaverse. The objectives of this book are to provide the basic concepts of DT, to explore the promising applications of DT integrated with emerging technologies, and to give insights into the possible future directions of DT. For easy understanding, this book also presents several use cases for DT models and applications in different scenarios. The book starts with the basic concepts, models, and network architectures of DT. Then, we present the new opportunities when DT meets edge computing, Blockchain and Artificial Intelligence, and distributed machine learning (e.g., federated learning, multi-agent deep reinforcement learning). We also present a wide application of DT as an enabling technology for 6G networks, Aerial-Ground Networks, and Unmanned Aerial Vehicles (UAVs). The book allows an easy cross-reference owing to the broad coverage on both the principle and applications of DT. The book is written for people interested in communications and computer networks at all levels. The primary audience includes senior undergraduates, postgraduates, educators, scientists, researchers, developers, engineers, innovators and research strategists.
The scaling-up of electrochemical CO2 reduction requires circumventing the CO2 loss as carbonates under alkaline conditions. Zero-gap cell configurations with a reverse-bias bipolar membrane (BPM) ...represent a possible solution, but the catalyst layer in direct contact with the acidic environment of a BPM usually leads to H2 evolution dominating. Here we show that using acid-tolerant Ni molecular electrocatalysts selective (>60%) CO2 reduction can be achieved in a zero-gap BPM device using a pure water and CO2 feed. At a higher current density (100 mA cm–2), CO selectivity decreases, but was still >30%, due to reversible product inhibition. This study demonstrates the importance of developing acid-tolerant catalysts for use in large-scale CO2 reduction devices.
Research in Communication Sciences and Disorders: Methods for Systematic Inquiry, Fourth Edition is a comprehensive yet comprehendible text meant for instructors and students of research methods in ...the field of communication sciences and disorders. This forward-thinking book reflects the movement toward evidence-based practice in speech-language pathology and audiology.
Societies around the world have experienced a flood of information from diverse channels originating beyond local communities and even national borders, transmitted through the rapid expansion of ...cosmopolitan communications. For more than half a century, conventional interpretations, Norris and Inglehart argue, have commonly exaggerated the potential threats arising from this process. A series of firewalls protect national cultures. This book develops a new theoretical framework for understanding cosmopolitan communications and uses it to identify the conditions under which global communications are most likely to endanger cultural diversity. The authors analyze empirical evidence from both the societal level and the individual level, examining the outlook and beliefs of people in a wide range of societies. The study draws on evidence from the World Values Survey, covering 90 societies in all major regions worldwide from 1981 to 2007. The conclusion considers the implications of their findings for cultural policies.
This thoroughly updated fourth edition of Clinical Research in Communication Disorders: Principles and Strategies remains an instrumental resource for courses on research methods and design in ...communication disorders. The book is separated into three key sections: science and the scientific methods, clinical research designs, and doing, reporting, and evaluating research. Together, these sections provide thorough coverage of both the single-subject and group design strategies along with issues of measurement; philosophy of science; ethics of research; and planning, conducting, and reporting research. Instructors and students in communication sciences and disorders will appreciate the text's comprehensive coverage of scientific methods, group and single-subject research designs, report writing, and ethics of research in a single source.
Now available to an English-speaking audience, this book presents a groundbreaking theoretical analysis of memory, identity and culture. It investigates how cultures remember, arguing that human ...memory exists and is communicated in two ways, namely inter-human interaction and in external systems of notation, such as writing, which can span generations. Dr Assmann defines two theoretical concepts of cultural memory, differentiating between the long-term memory of societies, which can span up to 3,000 years, and communicative memory, which is typically restricted to 80 to 100 years. He applies this theoretical framework to case studies of four specific cultures, illustrating the function contexts and specific achievements, including the state, international law, religion and science. Ultimately, his research demonstrates that memory is not simply a means of retaining information, but rather a force that can shape cultural identity and allow cultures to respond creatively to both daily challenges and catastrophic changes.
Ten autistic self-advocates share their experiences with alternative forms of communication such as rapid prompting method (RPM) and facilitated communication (FC), both highly controversial. Their ...narratives document the complexities that autistic individuals navigate--in both educational and community settings--when choosing to use approaches that utilize letter boards and keyboards. While the controversies remain--RPM requires further scientific study, and FC is subject to criticism about confirmation bias--these individuals share powerful stories in the context of aiming for disability rights. The book concludes with a chapter about best practices for educators, particularly for schools and colleges that have students who use these communication methods.
