Book Description
Telecommunications have underpinned social interaction and economic activity since the 19th century and have been increasingly reliant on optical fibers since their initial commercial deployment by BT in 1983. Today, mobile phone networks, data centers, and broadband services that facilitate our entertainment, commerce, and increasingly health provision are built on hidden optical fiber networks. However, recently it emerged that the fiber network is beginning to fill up, leading to the talk of a capacity crunch where the capacity still grows but struggles to keep up with the increasing demand. This book, featuring contributions by the suppliers of widely deployed simulation software and academic authors, illustrates the origins of the limited performance of an optical fiber from the engineering, physics, and information theoretic viewpoints. Solutions are then discussed by pioneers in each of the respective fields, with near-term solutions discussed by industrially based authors, and more speculative high-potential solutions discussed by leading academic groups.

Book Description
How do journalists know what they know? Who gets to decide what good journalism is and when it's done right? What sort of expertise do journalists have, and what role should and do they play in society? Until a couple of decades ago, journalists rarely asked these questions, largely because the answers were generally undisputed. Now, the stakes are rising for journalists as they face real-time critique and audience pushback for their ethics, news reporting, and relevance. Yet the crises facing journalism have been narrowly defined as the result of disruption by new technologies and economic decline. This book argues that the concerns are in fact much more profound. Drawing on their five years of research with journalists in the U.S. and Canada, in a variety of news organizations from startups and freelancers to mainstream media, the authors find a digital reckoning taking place regarding journalism's founding ideals and methods. The book explores journalism's long-standing representational harms, arguing that despite thoughtful explorations of the role of publics in journalism, the profession hasn't adequately addressed matters of gender, race, intersectionality, and settler colonialism. In doing so, the authors rethink the basis for what journalism says it could and should do, suggesting that a turn to strong objectivity and systems journalism provides a path forward. They offer insights from journalists' own experiences and efforts at repair, reform, and transformation to consider how journalism can address its limits and possibilities along with widening media publics.

Book Description
Intended for practitioners, this study has three principal aims: (1) to reduce the breadth of formal grammar instruction by first locating those areas where grammar and writing overlap and then identifying those kinds of writing problems most amenable to treatment with a grammar-based approach; (2) to decrease the classroom hours spent on formal grammar instruction by showing how to capitalize on the already acquired yet unconscious knowledge that all native writers have of their language; and (3) to make this streamlined "writer's grammar" more productive by showing how to integrate it with style, content, and organization. The book is directed toward teachers of writing who, to varying degrees, struggle with the unwieldy partnership of grammar and writing. Chapters 1 and 2 serve to examine some probable reasons why grammar instruction has failed to improve writing quality, to delimit radically the scope of grammar instruction, and to identify specific areas where a knowledge of a minimal set of grammatical categories might be of help. Chapters 3 and 4 focus on the use of native-speaker abilities in place of formal grammar instruction to treat certain kinds of sentence-level writing problems. Chapter 5 suggests a promising way to integrate the diminished focus on grammar with style, content, and organization. Finally, chapter 6 summarizes several pragmatic paradoxes that currently beset grammar instruction in the schools. (MG)

Book Description
Is the Miranda warning, which lets an accused know of the right to remain silent, more about procedural fairness or about the conventions of speech acts and silences? Do U.S. laws about Native Americans violate the preferred or traditional "silence" of the peoples whose religions and languages they aim to "protect" and "preserve"? In Just Silences, Marianne Constable draws on such examples to explore what is at stake in modern law: a potentially new silence as to justice. Grounding her claims about modern law in rhetorical analyses of U.S. law and legal texts and locating those claims within the tradition of Nietzsche, Heidegger, and Foucault, Constable asks what we are to make of silences in modern law and justice. She shows how what she calls "sociolegal positivism" is more important than the natural law/positive law distinction for understanding modern law. Modern law is a social and sociological phenomenon, whose instrumental, power-oriented, sometimes violent nature raises serious doubts about the continued possibility of justice. She shows how particular views of language and speech are implicated in such law. But law--like language--has not always been positivist, empirical, or sociological, nor need it be. Constable examines possibilities of silence and proposes an alternative understanding of law--one that emerges in the calling, however silently, of words to justice. Profoundly insightful and fluently written, Just Silences suggests that justice today lies precariously in the silences of modern positive law.

Book Description
A Holocaust survivor's surprising and thought-provoking study of forgiveness, justice, compassion, and human responsibility, featuring contributions from the Dalai Lama, Harry Wu, Cynthia Ozick, Primo Levi, and more. You are a prisoner in a concentration camp. A dying Nazi soldier asks for your forgiveness. What would you do? While imprisoned in a Nazi concentration camp, Simon Wiesenthal was taken one day from his work detail to the bedside of a dying member of the SS. Haunted by the crimes in which he had participated, the soldier wanted to confess to--and obtain absolution from--a Jew. Faced with the choice between compassion and justice, silence and truth, Wiesenthal said nothing. But even years after the way had ended, he wondered: Had he done the right thing? What would you have done in his place? In this important book, fifty-three distinguished men and women respond to Wiesenthal's questions. They are theologians, political leaders, writers, jurists, psychiatrists, human rights activists, Holocaust survivors, and victims of attempted genocides in Bosnia, Cambodia, China and Tibet. Their responses, as varied as their experiences of the world, remind us that Wiesenthal's questions are not limited to events of the past.

Book Description
Attention to embodiment and the religious significance of bodies is one of the most significant shifts in contemporary theology. In the midst of this, however, experiences of disability have received little attention. This book explores possibilities for theological engagement with disability, focusing on three primary alternatives: challenging existing theological models to engage with the disabled body, considering possibilities for a disability liberation theology, and exploring new theological options based on an understanding of the unsurprisingness of human limits. The overarching perspective of this book is that limits are an unavoidable aspect of being human, a fact we often seem to forget or deny. Yet not only do all humans experience limits, most of us also experience limits that take the form of disability at some point in our lives; in this way, disability is more "normal" than non-disability. If we take such experiences seriously and refuse to reduce them to mere instances of suffering, we discover insights that are lost when we take a perfect or generic body as our starting point for theological reflections. While possible applications of this insight are vast, this work focuses on two areas of particular interest: theological anthropology and metaphors for God. This project challenges theology to consider the undeniable diversity of human embodiment. It also enriches previous disability work by providing an alternative to the dominant medical and minority models, both of which fail to acknowledge the full diversity of disability experiences. Most notably, this project offers new images and possibilities for theological construction that attend appropriately and creatively to diversity in human embodiment.

Book Description
Can moral behavior exist in a world of states? Under what conditions? Where if at all, do norms for moral behavior, considerations of right and wrong, fit int the relations between states? Drawing upon many historical examples, Stanley Hoffmann examines the complex questions of whether or not ethical action is possible in international politics and, if it is, what are the obstacles and constraints? Duties Beyond Borders tries to answer these questions and to suggest a course of “ethical politics” based on a pragmatic, realistic approach to international politics.
