Better without AI is a call to action. You can participate. This is for you. The enormous transformational potential of artificial intelligence has long been dismissed because AI itself sounds like science fiction. That is no longer possible. Fluent new text generators, such as ChatGPT, have suddenly shown that powerful AI is here now. We may respond with excitement for opportunities, concern with risks, or both. This book is about overlooked risks--not malevolent robots, but "moderate apocalypses," which could result from recent and near-future technologies. AI systems we cannot understand are already making major social and cultural decisions for us. That may crush our ability to make sense of the world--and so our ability to act in it. Feeling dazed and lost, we may descend into pervasive helplessness. Or, we may revolt against the machines--and in so doing, we may destroy systems we depend on for survival. Can we get the benefits of technological breakthroughs without succumbing to the risks? This book explains seven practical actions we can take to guard against disasters. Acting now is the best way to steer away--and perhaps toward a remarkably likable future. You, and everyone, can join in this effort. The most important questions are not about technology but about us. What sort of future would you like? How might AI help get us there? What is its role in that world? What is your own role in helping that happen?

This book is a collection of interwoven historical narratives that present an intriguing and little known account of the Ogasawara (Bonin) archipelago and its inhabitants. The narratives begin in the seventeenth century and weave their way through various events connected to the ambitions, hopes, and machinations of individuals, communities, and nations. At the center of these narratives are the Bonin Islanders, originally an eclectic mix of Pacific Islanders, Americans, British, French, German, Portuguese, Italian, and African settlers that first landed on the islands in 1830. The islands were British sovereign territory from 1827 to 1876, when the Japanese asserted possession of the islands based on a seventeenth century expedition and a myth of a samurai discoverer. As part of gaining sovereign control, the Japanese government made all island inhabitants register as Japanese subjects of the national family register. The islanders were not literate in Japanese and had little experience of Japanese culture and limited knowledge of Japanese society, but by 1881 all were forced or coerced into becoming Japanese subjects. By the 1930s the islands were embroiled in the Pacific War. All inhabitants were evacuated to the Japanese mainland until 1946 when only the descendants of the original settlers were allowed to return. In the postwar period the islands fell under U.S. Navy administration until they were reverted to full Japanese sovereignty in 1968. Many descendants of these original settlers still live on the islands with family names such as Washington, Gonzales, Gilley, Savory, and Webb. This book explores the social and cultural history of these islands and its inhabitants and provides a critical approach to understanding the many complex narratives that make up the Bonin story.

This textbook will provide both undergraduates and practising engineers with an up-to-date and thorough grounding in the concepts of modern digital transmission. The book is not encyclopaedic, rather it selects the key concepts and processes and explains them in a deliberate pedagogic style. These concepts and processes are then illustrated by a number of system descriptions. The book is divided into three parts. The longest, Part II, describes the basic processes of digital transmission, such as matched filter detection, pulse shaping, line coding, channel coding, error detection and correction, etc. Understanding the concepts behind these processes requires a grasp of basic mathematical models, and this is provided in Part I. Finally, to put the processes in context, Part III describes elements of the public switched telephone network. The text is written throughout in a modern, digital context, and is comprehensively illustrated with helpful figures. Although the mathematical models (time- and frequency-domain concepts) have wider relevance, they are developed specifically for modelling digital signals. The processes described are those found in current transmission systems, and the description of the PSTN includes an outline of newly formulated standards for the synchronous digital hierarchy (SDH), SONET and for broadband ISDN (ATM). The book will be of great value to 2nd and 3rd year undergraduates studying telecommunications, as well as to graduate trainees and practising engineers. It is appropriate for either private study or as a text associated with a taught telecommunications course. The many worked examples and exercises with solutions will be particularly helpful.

Based on country studies in Ethiopia, Ghana, Guinea, Madagascar, Tanzania and Uganda and a literature review. This paper suggests several critical and promising areas for improvement in the quality of secondary teachers through new approaches to recruitment; and pre-service and in-service teacher development.
