Download or read book Inside PixInsight written by Warren A. Keller and published by Springer. This book was released on 2016-09-09 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Warren Keller reveals the secrets of astro-image processing software PixInsight in a practical and easy to follow manner, allowing the reader to produce stunning astrophotographs from even mediocre data. As the first comprehensive post-processing platform to be created by astro-imagers for astro-imagers, it has for many, replaced the generic graphics editors as the software of choice. With clear instructions from Keller, astrophotographers can get the most from its tools to create amazing images. Capable of complex post-processing routines, PixInsight is also an advanced pre-processing software, through which astrophotographers calibrate and stack their exposures into completed master files. Although it is extremely powerful, PixInsight has been inadequately documented in print--until now. With screenshots to help illustrate the process, it is a vital guide.

Available in PDF, EPUB and Kindle. Book excerpt: For all but the simplest star-trail pictures, photographing the night sky involves machinery to track the stars, and the task becomes even more complicated when photographing very small or very faint objects that require high magnification or very long exposure times. Astrophotography for Amateurs presents equipment and techniques, features practical hints and tips from the experts, including coverage of traditional "wet" photography, CCD imaging, and computerized image enhancement. There are sections on photographing different classes of astronomical object from the moon to faint nebulae, as well as a detailed look at the equipment needed.

Download or read book Anthropic Bias written by Nick Bostrom and published by Routledge. This book was released on 2013-10-11 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropic Bias explores how to reason when you suspect that your evidence is biased by "observation selection effects"--that is, evidence that has been filtered by the precondition that there be some suitably positioned observer to "have" the evidence. This conundrum--sometimes alluded to as "the anthropic principle," "self-locating belief," or "indexical information"--turns out to be a surprisingly perplexing and intellectually stimulating challenge, one abounding with important implications for many areas in science and philosophy. There are the philosophical thought experiments and paradoxes: the Doomsday Argument; Sleeping Beauty; the Presumptuous Philosopher; Adam & Eve; the Absent-Minded Driver; the Shooting Room. And there are the applications in contemporary science: cosmology ("How many universes are there?", "Why does the universe appear fine-tuned for life?"); evolutionary theory ("How improbable was the evolution of intelligent life on our planet?"); the problem of time's arrow ("Can it be given a thermodynamic explanation?"); quantum physics ("How can the many-worlds theory be tested?"); game-theory problems with imperfect recall ("How to model them?"); even traffic analysis ("Why is the 'next lane' faster?"). Anthropic Bias argues that the same principles are at work across all these domains. And it offers a synthesis: a mathematically explicit theory of observation selection effects that attempts to meet scientific needs while steering clear of philosophical paradox.

Download or read book Press Bias and Politics written by Jim A. Kuypers and published by Praeger. This book was released on 2002-09-30 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kuypers charts the potential effects the printed presses and broadcast media have upon the messages of political and social leaders when they discuss controversial issues. Examining over 800 press reports on race and homosexuality from 116 different newspapers, Kuypers meticulously documents a liberal political bias in mainstream news. This book asserts that such a bias hurts the democratic process by ignoring non-mainstream left positions and vilifying many moderate and most right-leaning positions, leaving only a narrow brand of liberal thought supported by the mainstream press. This book argues that the mainstream press in America is an anti-democratic institution. By comparatively analyzing press reports, as well as the events that occasioned the coverage, Kuypers paints a detailed picture of the politics of the American press. He advances four distinct reportorial practices that inject bias into reporting, offering perspectives of particular interest to scholars, students, and others involved with mass communication, journalism, and politics in the United States.

Download or read book Choices Values and Frames written by Daniel Kahneman and published by Cambridge University Press. This book was released on 2000-09-25 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the definitive exposition of 'prospect theory', a compelling alternative to the classical utility theory of choice. Building on the 1982 volume, Judgement Under Uncertainty, this book brings together seminal papers on prospect theory from economists, decision theorists, and psychologists, including the work of the late Amos Tversky, whose contributions are collected here for the first time. While remaining within a rational choice framework, prospect theory delivers more accurate, empirically verified predictions in key test cases, as well as helping to explain many complex, real-world puzzles. In this volume, it is brought to bear on phenomena as diverse as the principles of legal compensation, the equity premium puzzle in financial markets, and the number of hours that New York cab drivers choose to drive on rainy days. Theoretically elegant and empirically robust, this volume shows how prospect theory has matured into a new science of decision making.

Download or read book News Framing Effects written by Sophie Lecheler and published by Routledge. This book was released on 2018-09-03 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: News Framing Effects is a guide to framing effects theory, one of the most prominent theories in media and communication science. Rooted in both psychology and sociology, framing effects theory describes the ability of news media to influence people’s attitudes and behaviors by subtle changes to how they report on an issue. The book gives expert commentary on this complex theoretical notion alongside practical instruction on how to apply it to research. The book’s structure mirrors the steps a scholar might take to design a framing study. The first chapter establishes a working definition of news framing effects theory. The following chapters focus on how to identify the independent variable (i.e., the "news frame") and the dependent variable (i.e., the "framing effect"). The book then considers the potential limits or enhancements of the proposed effects (i.e., the "moderators") and how framing effects might emerge (i.e., the "mediators"). Finally, it asks how strong these effects are likely to be. The final chapter considers news framing research in the light of a rapidly and fundamentally changing news and information market, in which technologies, platforms, and changing consumption patterns are forcing assumptions at the core of framing effects theory to be re-evaluated.

Book excerpt: Through a mix of nature, nurture, social conditioning and free will, we each possess a personalized lens that frames, forms, clouds and distorts the way we see ourselves and the world around us. In order to live in the most meaningful and effective way possible, each of us needs to continually assess and adjust the default frames we have developed.In Positivity Bias, we learn that life is essentially good; that positive perception is applicable and accessible to all; that it derives from objective, rational insight, not subjective, wishful imagination, and that positive living is a matter of choice, not circumstance.An inspiring and life-enriching tapestry woven from hundreds of stories, letter, anecdotes, and vignettes - Positivity Bias highlights how the Lubavitcher Rebbe, Rabbi Menachem M. Schneerson, of righteous memory, considered the most influential rabbi in modern history, taught us to see ourselves, others, and the world around us.

Download or read book Race After Technology written by Ruha Benjamin and published by John Wiley & Sons. This book was released on 2019-07-09 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: From everyday apps to complex algorithms, Ruha Benjamin cuts through tech-industry hype to understand how emerging technologies can reinforce White supremacy and deepen social inequity. Benjamin argues that automation, far from being a sinister story of racist programmers scheming on the dark web, has the potential to hide, speed up, and deepen discrimination while appearing neutral and even benevolent when compared to the racism of a previous era. Presenting the concept of the “New Jim Code,” she shows how a range of discriminatory designs encode inequity by explicitly amplifying racial hierarchies; by ignoring but thereby replicating social divisions; or by aiming to fix racial bias but ultimately doing quite the opposite. Moreover, she makes a compelling case for race itself as a kind of technology, designed to stratify and sanctify social injustice in the architecture of everyday life. This illuminating guide provides conceptual tools for decoding tech promises with sociologically informed skepticism. In doing so, it challenges us to question not only the technologies we are sold but also the ones we ourselves manufacture. Visit the book's free Discussion Guide: www.dropbox.com

Download or read book Blindspot written by Mahzarin R. Banaji and published by Bantam. This book was released on 2016-08-16 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Accessible and authoritative . . . While we may not have much power to eradicate our own prejudices, we can counteract them. The first step is to turn a hidden bias into a visible one. . . . What if we’re not the magnanimous people we think we are?”—The Washington Post I know my own mind. I am able to assess others in a fair and accurate way. These self-perceptions are challenged by leading psychologists Mahzarin R. Banaji and Anthony G. Greenwald as they explore the hidden biases we all carry from a lifetime of exposure to cultural attitudes about age, gender, race, ethnicity, religion, social class, sexuality, disability status, and nationality. “Blindspot” is the authors’ metaphor for the portion of the mind that houses hidden biases. Writing with simplicity and verve, Banaji and Greenwald question the extent to which our perceptions of social groups—without our awareness or conscious control—shape our likes and dislikes and our judgments about people’s character, abilities, and potential. In Blindspot, the authors reveal hidden biases based on their experience with the Implicit Association Test, a method that has revolutionized the way scientists learn about the human mind and that gives us a glimpse into what lies within the metaphoric blindspot. The title’s “good people” are those of us who strive to align our behavior with our intentions. The aim of Blindspot is to explain the science in plain enough language to help well-intentioned people achieve that alignment. By gaining awareness, we can adapt beliefs and behavior and “outsmart the machine” in our heads so we can be fairer to those around us. Venturing into this book is an invitation to understand our own minds. Brilliant, authoritative, and utterly accessible, Blindspot is a book that will challenge and change readers for years to come. Praise for Blindspot “Conversational . . . easy to read, and best of all, it has the potential, at least, to change the way you think about yourself.”—Leonard Mlodinow, The New York Review of Books “Banaji and Greenwald deserve a major award for writing such a lively and engaging book that conveys an important message: Mental processes that we are not aware of can affect what we think and what we do. Blindspot is one of the most illuminating books ever written on this topic.”—Elizabeth F. Loftus, Ph.D., distinguished professor, University of California, Irvine; past president, Association for Psychological Science; author of Eyewitness Testimony

Download or read book Encyclopedia of Survey Research Methods written by Paul J. Lavrakas and published by SAGE Publications. This book was released on 2008-09-12 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the uninformed, surveys appear to be an easy type of research to design and conduct, but when students and professionals delve deeper, they encounter the vast complexities that the range and practice of survey methods present. To complicate matters, technology has rapidly affected the way surveys can be conducted; today, surveys are conducted via cell phone, the Internet, email, interactive voice response, and other technology-based modes. Thus, students, researchers, and professionals need both a comprehensive understanding of these complexities and a revised set of tools to meet the challenges. In conjunction with top survey researchers around the world and with Nielsen Media Research serving as the corporate sponsor, the Encyclopedia of Survey Research Methods presents state-of-the-art information and methodological examples from the field of survey research. Although there are other "how-to" guides and references texts on survey research, none is as comprehensive as this Encyclopedia, and none presents the material in such a focused and approachable manner. With more than 600 entries, this resource uses a Total Survey Error perspective that considers all aspects of possible survey error from a cost-benefit standpoint. Key Features Covers all major facets of survey research methodology, from selecting the sample design and the sampling frame, designing and pretesting the questionnaire, data collection, and data coding, to the thorny issues surrounding diminishing response rates, confidentiality, privacy, informed consent and other ethical issues, data weighting, and data analyses Presents a Reader′s Guide to organize entries around themes or specific topics and easily guide users to areas of interest Offers cross-referenced terms, a brief listing of Further Readings, and stable Web site URLs following most entries The Encyclopedia of Survey Research Methods is specifically written to appeal to beginning, intermediate, and advanced students, practitioners, researchers, consultants, and consumers of survey-based information.

Download or read book Unconscious Bias in Schools written by Tracey A. Benson and published by Harvard Education Press. This book was released on 2020-07-22 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Unconscious Bias in Schools, two seasoned educators describe the phenomenon of unconscious racial bias and how it negatively affects the work of educators and students in schools. “Regardless of the amount of effort, time, and resources education leaders put into improving the academic achievement of students of color,” the authors write, “if unconscious racial bias is overlooked, improvement efforts may never achieve their highest potential.” In order to address this bias, the authors argue, educators must first be aware of the racialized context in which we live. Through personal anecdotes and real-life scenarios, Unconscious Bias in Schools provides education leaders with an essential roadmap for addressing these issues directly. The authors draw on the literature on change management, leadership, critical race theory, and racial identity development, as well as the growing research on unconscious bias in a variety of fields, to provide guidance for creating the conditions necessary to do this work—awareness, trust, and a “learner’s stance.” Benson and Fiarman also outline specific steps toward normalizing conversations about race; reducing the influence of bias on decision-making; building empathic relationships; and developing a system of accountability. All too often, conversations about race become mired in questions of attitude or intention–“But I’m not a racist!” This book shows how information about unconscious bias can help shift conversations among educators to a more productive, collegial approach that has the potential to disrupt the patterns of perception that perpetuate racism and institutional injustice. Tracey A. Benson is an assistant professor of educational leadership at the University of North Carolina at Charlotte. Sarah E. Fiarman is the director of leadership development for EL Education, and a former public school teacher, principal, and lecturer at Harvard Graduate School of Education.

Download or read book Race on the Brain written by Jonathan Kahn and published by Columbia University Press. This book was released on 2017-11-07 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the many obstacles to racial justice in America, none has received more recent attention than the one that lurks in our subconscious. As social movements and policing scandals have shown how far from being “postracial” we are, the concept of implicit bias has taken center stage in the national conversation about race. Millions of Americans have taken online tests purporting to show the deep, invisible roots of their own prejudice. A recent Oxford study that claims to have found a drug that reduces implicit bias is only the starkest example of a pervasive trend. But what do we risk when we seek the simplicity of a technological diagnosis—and solution—for racism? What do we miss when we locate racism in our biology and our brains rather than in our history and our social practices? In Race on the Brain, Jonathan Kahn argues that implicit bias has grown into a master narrative of race relations—one with profound, if unintended, negative consequences for law, science, and society. He emphasizes its limitations, arguing that while useful as a tool to understand particular types of behavior, it is only one among several tools available to policy makers. An uncritical embrace of implicit bias, to the exclusion of power relations and structural racism, undermines wider civic responsibility for addressing the problem by turning it over to experts. Technological interventions, including many tests for implicit bias, are premised on a color-blind ideal and run the risk of erasing history, denying present reality, and obscuring accountability. Kahn recognizes the significance of implicit social cognition but cautions against seeing it as a panacea for addressing America’s longstanding racial problems. A bracing corrective to what has become a common-sense understanding of the power of prejudice, Race on the Brain challenges us all to engage more thoughtfully and more democratically in the difficult task of promoting racial justice.

Download or read book Cognitive Biases in Visualizations written by Geoffrey Ellis and published by Springer. This book was released on 2018-09-27 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the latest research in this new and exciting area of visualization, looking at classifying and modelling cognitive biases, together with user studies which reveal their undesirable impact on human judgement, and demonstrating how visual analytic techniques can provide effective support for mitigating key biases. A comprehensive coverage of this very relevant topic is provided though this collection of extended papers from the successful DECISIVe workshop at IEEE VIS, together with an introduction to cognitive biases and an invited chapter from a leading expert in intelligence analysis. Cognitive Biases in Visualizations will be of interest to a wide audience from those studying cognitive biases to visualization designers and practitioners. It offers a choice of research frameworks, help with the design of user studies, and proposals for the effective measurement of biases. The impact of human visualization literacy, competence and human cognition on cognitive biases are also examined, as well as the notion of system-induced biases. The well referenced chapters provide an excellent starting point for gaining an awareness of the detrimental effect that some cognitive biases can have on users’ decision-making. Human behavior is complex and we are only just starting to unravel the processes involved and investigate ways in which the computer can assist, however the final section supports the prospect that visual analytics, in particular, can counter some of the more common cognitive errors, which have been proven to be so costly.

Download or read book Nonresponse in Social Science Surveys written by National Research Council and published by National Academies Press. This book was released on 2013-10-26 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many household surveys in the United States, responses rates have been steadily declining for at least the past two decades. A similar decline in survey response can be observed in all wealthy countries. Efforts to raise response rates have used such strategies as monetary incentives or repeated attempts to contact sample members and obtain completed interviews, but these strategies increase the costs of surveys. This review addresses the core issues regarding survey nonresponse. It considers why response rates are declining and what that means for the accuracy of survey results. These trends are of particular concern for the social science community, which is heavily invested in obtaining information from household surveys. The evidence to date makes it apparent that current trends in nonresponse, if not arrested, threaten to undermine the potential of household surveys to elicit information that assists in understanding social and economic issues. The trends also threaten to weaken the validity of inferences drawn from estimates based on those surveys. High nonresponse rates create the potential or risk for bias in estimates and affect survey design, data collection, estimation, and analysis. The survey community is painfully aware of these trends and has responded aggressively to these threats. The interview modes employed by surveys in the public and private sectors have proliferated as new technologies and methods have emerged and matured. To the traditional trio of mail, telephone, and face-to-face surveys have been added interactive voice response (IVR), audio computer-assisted self-interviewing (ACASI), web surveys, and a number of hybrid methods. Similarly, a growing research agenda has emerged in the past decade or so focused on seeking solutions to various aspects of the problem of survey nonresponse; the potential solutions that have been considered range from better training and deployment of interviewers to more use of incentives, better use of the information collected in the data collection, and increased use of auxiliary information from other sources in survey design and data collection. Nonresponse in Social Science Surveys: A Research Agenda also documents the increased use of information collected in the survey process in nonresponse adjustment.
