This book is a systematic summary of some new advances in the area of nonlinear analysis and design in the frequency domain, focusing on the application oriented theory and methods based on the GFRF concept, which is mainly done by the author in the past 8 years. The main results are formulated uniformly with a parametric characteristic approach, which provides a convenient and novel insight into nonlinear influence on system output response in terms of characteristic parameters and thus facilitate nonlinear analysis and design in the frequency domain. The book starts with a brief introduction to the background of nonlinear analysis in the frequency domain, followed by recursive algorithms for computation of GFRFs for different parametric models, and nonlinear output frequency properties. Thereafter the parametric characteristic analysis method is introduced, which leads to the new understanding and formulation of the GFRFs, and nonlinear characteristic output spectrum (nCOS) and the nCOS based analysis and design method. Based on the parametric characteristic approach, nonlinear influence in the frequency domain can be investigated with a novel insight, i.e., alternating series, which is followed by some application results in vibration control. Magnitude bounds of frequency response functions of nonlinear systems can also be studied with a parametric characteristic approach, which result in novel parametric convergence criteria for any given parametric nonlinear model whose input-output relationship allows a convergent Volterra series expansion. This book targets those readers who are working in the areas related to nonlinear analysis and design, nonlinear signal processing, nonlinear system identification, nonlinear vibration control, and so on. It particularly serves as a good reference for those who are studying frequency domain methods for nonlinear systems.
The first part of this new book concentrates on the office automation phenomenon. Chapter 1 sketches some of its disappointments and sets the stage for the chapters to follow. In Chapter 2, the author argues that images of organization incorporate what has been called a worldview and are thus inevitably relativistic in their orientation. This allows the author to criticize some common assumptions about the nature of organization, but it equally introduces a theme that is central to his theory, and that will be picked up again in a later chapter. Chapter 3 gets to the heart of his criticism of conventional theories of communication process, and in doing so allows the author to demonstrate the feet of clay of one of the sacred cows of our time: the concept of office work as information processing. The second part is concerned with theory and its implications. Chapter 4 describes the event of communication, in microcosm. Chapter 5 is an attempt to give this perception a more systematic presentation. Chapter 6 tries to understand the problem of operationalizing the theory, as a means to understanding, and studying the dynamics of conversation and of communication mediated through texts. Chapter 7 explores one implication of the theory, namely, the maintenance of requisite variety, within a conversational system. Chapter 8 concludes the presentation by a consideration of some of the implications of the theory for the conduct of research.

This book presents two practical physical attacks. It shows how attackers can reveal the secret key of symmetric as well as asymmetric cryptographic algorithms based on these attacks, and presents countermeasures on the software and the hardware level that can help to prevent them in the future. Though their theory has been known for several years now, since neither attack has yet been successfully implemented in practice, they have generally not been considered a serious threat. In short, their physical attack complexity has been overestimated and the implied security threat has been underestimated. First, the book introduces the photonic side channel, which offers not only temporal resolution, but also the highest possible spatial resolution. Due to the high cost of its initial implementation, it has not been taken seriously. The work shows both simple and differential photonic side channel analyses. Then, it presents a fault attack against pairing-based cryptography. Due to the need for at least two independent precise faults in a single pairing computation, it has not been taken seriously either. Based on these two attacks, the book demonstrates that the assessment of physical attack complexity is error-prone, and as such cryptography should not rely on it. Cryptographic technologies have to be protected against all physical attacks, whether they have already been successfully implemented or not. The development of countermeasures does not require the successful execution of an attack but can already be carried out as soon as the principle of a side channel or a fault attack is sufficiently understood.
This much-needed title is an introductory text for novice researchers - undergraduate students or junior postgraduate students who are encountering research methodology for the first time. A number of additional features make this title resource for scholars, academics, researchers, psychologists, social workers, teachers and clients: It gives an overview of international perspectives on research methodology. It critically analyses germane questions such as, "What is the language of research" and "How does one pose the right research question?" It facilitates an understanding and application of theories, goals, methods and strategies in research. It examines the historical and philosophical underpinnings of qualitative, quantitative and mixed methods research and suggests how these three approaches may be used to conduct research.
Examines the diverse uses and abuses of risk by social actors across a wide range of cultural, ethnic, and geographical locales. The introductory chapter by the two co-editors analyzes and contextualizes current scholarly debates on the social, cultural, and political construction of risk. It is followed by an overview on the anthropology of harm reduction that outlines an innovative framework for culturally informed risk analysis. The remaining nine chapters are organized into three sections, The Cultivation of Fear, Perceptions of Health, Safety, and Hazard: Risk Makers and Risk Takers, and Regulating Risk and the Public's Health. The book aims to address a set of questions of theoretical and practical importance to anthropologists, sociologists, public health scholars and professionals, and public policy advocates, among others. These questions include: How do individuals conceptualize and respond to risk? Can risk be a tool of empowerment for individuals and communities who define themselves as at-risk? How has risk figured recently in the production of health inequality? Has the social contract to provide care in its broadest sense expanded or contracted around issues of risk? Are risk and the imperative to adhere to risk warnings used by experts as a means of social control? The volume's contributors, medical anthropologists and sociologists, provide rich, grounded ethnographic case material on the processes at work in everyday social life around the globe, as individuals and groups struggle to make saense of the health risks and inequities in their lives and communities. Authors address an array of urgent health concerns, ranging from food safety to environment, new technologies to infectious disease, in such contrasting locales as the US, Europe, South and Southeast Asia, and North Africa, and across diverse ethnicities and social classes.
This collection focuses on the multi-layered links between international events and identity discourses. With a unique line-up of international scholars, this book offers a diverse range of exciting case studies, including sports competitions, music festivals, exhibitions, fashion shows and royal celebrations.
This annotated document collection surveys the history and evolution of laws and attitudes regarding free speech and censorship in the United States, with a special emphasis on contemporary events and controversies related to the First Amendment. The United States' collective understanding of First Amendment freedoms was formed by more than 200 years of tensions between the power of word and the power of the government. During that time, major laws and legal decisions defined the circumstances and degree to which personal expression could be rightfully expressed-and rightfully limited. This struggle to define the parameters of free speech continues today. Vibrant and passionate debates about First Amendment limitations once inspired by the dissemination of birth control information now address such issues as kneeling during the national anthem, removing controversial books from public libraries, attempts by the Trump administration to discredit the press, and disseminating false or hateful information through social media platforms. By exploring diverse examples of censorship victories and triumphs of free expression, readers will better understand the enormous impact of First Amendment freedoms on American society. Chronological history of important milestones, documents, and events that have shaped the nation's understanding of freedom of speech/press and censorship, as well as the limitations of each Primary source selection that illuminates the importance of First Amendment freedoms as critical elements of democracy in the United States Informative, authoritative, and balanced introductory headnotes for each primary source to help readers understand the context in which they were created Readers Guide to Related Documents and sidebars

What is a "good life" and how can it be achieved? In this volume, communication scholars and media experts explore these fundamental questions about human existence and aspiration in terms of what a "good life" might look like in a contemporary, mediatized society. While in many ways a mediatized society brings us closer to some version of the "good life", it also leads us away from it. The affordances of new technologies seem to have shifted, for many, from an opportunity to an obligation. Rather than choosing when and where to be connected to these larger networks of information and acquaintances, we feel we must be permanently available, thus losing the luxury of controlling our time and attention. This volume illuminates the complexity of our modern era, exploring how society can leverage exciting new opportunities whilst recognizing the complex challenges we face in a time of constant change. It helps us understand how we have come to this point and where we may be going so that we may study the opportunities and the dangers, the chances and the risks, that digital media pose in our quest for some version of "the good life".
This book focuses on ethical and methodological issues faced by researchers working with young language learners in formal school contexts. It uncovers and explicitly discusses a range of ethical dilemmas, challenges and experiences that researchers have encountered and grappled with, in studies of all kinds from large scale, experimental studies to ethnographic studies focused on just a handful of children. The chapters are written by researchers working with children in different classroom contexts around the world and highlight how ethical dilemmas and tensions take on a complex form in child-focused research, requiring researchers to pay particular attention to the social and cultural norms of the different communities within which children are educated as well as their school-based experiences. The book comprises three sections, with the first part focused on involving children as active participants in research; part two on ethical challenges in multilingual contexts and part three on links between teacher education and researching children. The book includes a critical discussion of the opportunities and challenges associated with applying the UNCRC (1989) document in second language research with children which will be of use to any researcher working in this area.

Arranged for the most part geographically, the citations include descriptions of significant publications of books, pamphlets, theses and articles, as well as jubilee issues of Jewish newspapers and magazines. In addition to internal cross-references, the work also contains subject and author indexes.
In Ripples of Hope, Robert M. Press tells the stories of mothers, students, teachers, journalists, attorneys, and many others who courageously stood up for freedom and human rights against repressive rulers " and who helped bring about change through primarily nonviolent means. Global in application and focusing on Kenya, Liberia and Sierra Leone, this tribute to the strength of the human spirit also breaks new ground in social movement theories, showing how people on their own or in small groups can make a difference.
Cyberspace, Social Conflict, and Humanity: A Framework for Collapsing Disciplinary Barriers to Ethical Technology examines how our increasingly connected and digitized world is shaping our social experiences and interactions globally. It offers a new approach to human versus machine debate and builds the case for strategic collaboration between academia, industry, and governments who are committed to the humane advancement of knowledge and innovation. The text demonstrates how data and information can be used for or against any person, group, or a nation; the implication of cyber anxiety for states and nations; and how lack of ethical framework for the advancement of technology can lead to harmful results. It focuses on questions related to technological influence on society, individual privacy, cybercrimes and espionage, the battle over economy of attention and online engagement. By offering the latest case studies and examples, it offers ways to recognize and minimize the biases, misinformation, or disinformation within political and social context. Cyberspace, Social Conflict, and Humanity is ideal for courses in conflict resolution, social sciences, humanities, engineering, programming and multidisciplinary studies looking to the future of technology and society.

This book covers novel research on construction and analysis of optimal cryptographic functions such as almost perfect nonlinear (APN), almost bent (AB), planar and bent functions. These functions have optimal resistance to linear and/or differential attacks, which are the two most powerful attacks on symmetric cryptosystems. Besides cryptographic applications, these functions are significant in many branches of mathematics and information theory including coding theory, combinatorics, commutative algebra, finite geometry, sequence design and quantum information theory. The author analyzes equivalence relations for these functions and develops several new methods for construction of their infinite families. In addition, the book offers solutions to two longstanding open problems, including the problem on characterization of APN and AB functions via Boolean, and the problem on the relation between two classes of bent functions.
This book examines and compares policy making in telecommunications in Britain and France over the last three decades. The book examines questions related to liberalization, regulation and the role of the nation state in an increasingly international economy.
This book focuses on the issues of decision-making with several numerical criteria. It introduces an original general approach to solving multicriteria problems given quantitative information about the preference relation of a decision-maker. It considers the problems with crisp as well as fuzzy preference relations, accepting the four axioms of "reasonable choice". Further, it defines the notion of an information quantum about the preference relation of a decision-maker and studies the reduction of the Pareto set using a finite collection of information quanta, demonstrating that the original approach yields a good approximation for the set of nondominated alternatives in a multicriteria problem. Lastly, it analyzes a possible combination of the axiomatic approach with other well-known methods. Intended for a wide range of professionals involved in solving multicriteria problems, including researchers, design engineers, product engineers, developers and analysts, the book is also a valuable resource for undergraduate and postgraduate students of mathematics, economics, and engineering.
Fashion Writing and Criticism provides students with the tools to critique fashion with skill and style. Explaining the history and theory of criticism, this innovative text demonstrates how the tradition of criticism has developed and how this knowledge can be applied to fashion, enabling students to acquire the methods and proper vocabulary to be active critics themselves. Integrating history and theory, this innovative book explains the development of fashion writing, the theoretical basis on which it sits, and how it might be improved and applied. Through concise snapshot case studies, top international scholars McNeil and Miller analyse fashion excerpts in relation to philosophical ideas and situate them within historical contexts. Case studies include classic examples of fashion writing, such as Diana Vreeland at Harper's Bazaar and Richard Martin on Karl Lagerfeld, as well as contemporary examples such as Suzy Menkes and the blogger Tavi. Accessibly written, Fashion Writing and Criticism enables readers to understand, assess and make value judgments about the fascinating and changeable field of fashion. It is an invaluable text for students and researchers alike, studying fashion, journalism, history and media studies.
When research is so connected to personal interest, experience, and familiarity that objectivity becomes a moveable feast, the line between documentation and invention blurs to near-invisibility. John Freeman asks what it means to locate oneself into research findings and narrative reports, and what happens when one's self goes further and becomes the research. Subjecting received truths to a series of hard questions, readers are taken on a journey through self-performance; traumatic memoir; the lure of weasel words; emotional evocation; the vagaries of memory; creative nonfiction; cultural appropriation; illusion masquerading as truth and the complex ethics of university research. Case studies from international autoethnographers run through the book and appendices provide invaluable advice to university researchers and supervisors. The result is a work that sheds new light on forms of narrative research that connect writers' personal stories to the participatory cultures under investigation.
Increasingly, young people live online, with the vast majority of their social and cultural interactions conducted through means other than face-to-face conversation. How does this transition impact the ways in which young migrants understand, negotiate, and perform identity? That's the question taken up by Digital Passages: Migrant Youth 2.0, a ground-breaking analysis of the ways that youth culture online interacts with issues of diaspora, gender, and belonging. Drawing on surveys, in-depth interviews, and ethnography, Koen Leurs builds an interdisciplinary portrait of online youth culture and the spaces it opens up for migrant youth to negotiate power relations and to promote intercultural understanding.
The 21st century has seen a board game renaissance. At a time when streaming television finds millions of viewers, video games garner billions of dollars, and social media grows ever more intense, little has been written about the rising popularity of board games. And yet board games are one of our fastest growing hobbies, with sales increasing every year. Today's board games are more than just your average rainy-day mainstay. Once associated solely with geek subcultures, complex and strategic board games are increasingly dominating the playful media environment. The popularity of these complex board games mirrors the rise of more complex cult media products. In Game Play: Paratextuality in Contemporary Board Games, Paul Booth examines complex board games based on book, TV, and film franchises, including Doctor Who, The Walking Dead, Lord of the Rings, Star Trek, The Hunger Games and the worlds of H.P. Lovecraft. How does a game represent a cult world? How can narratives cross media platforms? By investigating the relationship between these media products and their board game versions, Booth illustrates the connections between cult media, gameplay, and narrative in a digital media environment. |
