The classic easy-reference field guide with more than 1500 photographs: “An almost foolproof practical reference book.” —Kirkus Reviews (starred review) This useful book for botanists, horticulturists, and nature lovers is made up of two parts: Pictorial Keys and Master Pages. The Keys are designed for easy visual comparison of details that look alike, narrowing the identification of a tree to one of a small group—the family or genus. Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

Since the mid-nineteenth century, there has been a notable acceleration in the development of the techniques used to confirm identity. From fingerprints to photographs to DNA, we have been rapidly amassing novel means of identification, even as personal, individual identity remains a complex chimera. The Art of Identification examines how such processes are entangled within a wider sphere of cultural identity formation. Against the backdrop of an unstable modernity and the rapid rise and expansion of identificatory techniques, this volume makes the case that identity and identification are mutually imbricated and that our best understanding of both concepts and technologies comes through the interdisciplinary analysis of science, bureaucratic infrastructures, and cultural artifacts. With contributions from literary critics, cultural historians, scholars of film and new media, a forensic anthropologist, and a human bioarcheologist, this book reflects upon the relationship between the bureaucratic, scientific, and technologically determined techniques of identification and the cultural contexts of art, literature, and screen media. In doing so, it opens the interpretive possibilities surrounding identification and pushes us to think about it as existing within a range of cultural influences that complicate the precise formulation, meaning, and reception of the concept. In addition to the editors, the contributors to this volume include Dorothy Butchard, Patricia E. Chu, Jonathan Finn, Rebecca Gowland, Liv Hausken, Matt Houlbrook, Rob Lederer, Andrew Mangham, Victoria Stewart, and Tim Thompson.

This book is a full-scale exposition of Charles Manski's new methodology for analyzing empirical questions in the social sciences. He recommends that researchers first ask what can be learned from data alone, and then ask what can be learned when data are combined with credible weak assumptions. Inferences predicated on weak assumptions, he argues, can achieve wide consensus, while ones that require strong assumptions almost inevitably are subject to sharp disagreements. Building on the foundation laid in the author's Identification Problems in the Social Sciences (Harvard, 1995), the book's fifteen chapters are organized in three parts. Part I studies prediction with missing or otherwise incomplete data. Part II concerns the analysis of treatment response, which aims to predict outcomes when alternative treatment rules are applied to a population. Part III studies prediction of choice behavior. Each chapter juxtaposes developments of methodology with empirical or numerical illustrations. The book employs a simple notation and mathematical apparatus, using only basic elements of probability theory.

This book summarizes the research advances in star identification that the author’s team has made over the past 10 years, systematically introducing the principles of star identification, general methods, key techniques and practicable algorithms. It also offers examples of hardware implementation and performance evaluation for the star identification algorithms. Star identification is the key step for celestial navigation and greatly improves the performance of star sensors, and as such the book include the fundamentals of star sensors and celestial navigation, the processing of the star catalog and star images, star identification using modified triangle algorithms, star identification using star patterns and using neural networks, rapid star tracking using star matching between adjacent frames, as well as implementation hardware and using performance tests for star identification. It is not only valuable as a reference book for star sensor designers and researchers working in pattern recognition and other related research fields, but also as teaching resource for senior postgraduate and graduate students majoring in information processing, computer science, artificial intelligence, aeronautics and astronautics, automation and instrumentation.

Some 600 million children worldwide do not legally exist. Without verifiable identification, they—and unregistered adults—could face serious difficulties in proving their identity, whether to open a bank account, purchase a SIM card, or cast a vote. Lack of identification is a barrier to full economic and social inclusion. Recent advances in the reach and technological sophistication of identification systems have been nothing less than revolutionary. Since 2000, over 60 developing countries have established national ID programs. Digital technology, particularly biometrics such as fingerprints and iris scans, has dramatically expanded the capabilities of these programs. Individuals can now be uniquely identified and reliably authenticated against their claimed identities. By enabling governments to work more effectively and transparently, identification is becoming a tool for accelerating development progress. Not only is provision of legal identity for all a target under the Sustainable Development Goals, but this book shows how it is also central to achieving numerous other SDG targets. Yet, challenges remain. Identification systems can fail to include the poor, leaving them still unable to exercise their rights, access essential services, or fully participate in political and economic life. The possible erosion of privacy and the misuse of personal data, especially in countries that lack data privacy laws or the capacity to enforce them, is another challenge. Yet another is ensuring that investments in identification systems deliver a development payoff. There are all too many examples where large expenditures—sometimes supported by donor governments or agencies—appear to have had little impact. Identification Revolution: Can Digital ID be Harnessed for Development? offers a balanced perspective on this new area, covering both the benefits and the risks of the identification revolution, as well as pinpointing opportunities to mitigate those risks.

Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries
