Book Description
Traditionally, the concept of quality of life has been viewed through objective indicators. Beyond Facts looks at quality of life through a new lens, namely, the perceptions of millions of Latin Americans. Using an enhanced version of the recently created Gallup World Poll that incorporates Latin America-specific questions, the Inter-American Development Bank surveyed people from throughout the region and found that perceptions of quality of life are often very different from the reality. These surprising findings have enormous significance for the political economy of the region and provide a wealth of information for policymakers and development practitioners to feast upon.

Book Description
It is widely acknowledged that a central aim of science is to achieve understanding of the world around us, and that possessing such understanding is highly important in our present-day society. But what does it mean to achieve this understanding? What precisely is scientific understanding? These are philosophical questions that have not yet received satisfactory answers. While there has been an ongoing debate about the nature of scientific explanation since Carl Hempel advanced his covering-law model in 1948, the related notion of understanding has been largely neglected, because most philosophers regarded understanding as merely a subjective by-product of objective explanations. By contrast, this book puts scientific understanding center stage. It is primarily a philosophical study, but also contains detailed historical case studies of scientific practice. In contrast to most existing studies in this area, it takes into account scientists' views and analyzes their role in scientific debate and development. The aim of Understanding Scientific Understanding is to develop and defend a philosophical theory of scientific understanding that can describe and explain the historical variation of criteria for understanding actually employed by scientists. The theory does justice to the insights of such famous physicists as Werner Heisenberg and Richard Feynman, while bringing much-needed conceptual rigor to their intuitions. The scope of the proposed account of understanding is the natural sciences: while the detailed case studies derive from physics, examples from other sciences are presented to illustrate its wider validity.

Book Description
New insights from the science of science Facts change all the time. Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing. Samuel Arbesman shows us how knowledge in most fields evolves systematically and predictably, and how this evolution unfolds in a fascinating way that can have a powerful impact on our lives. He takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries.

Book Description
Many deny that racism remains pervasive in America today. How can we open eyes to the continuing disadvantages that keep many people of color from fulfilling their potential, and having an equal chance to achieve the “American Dream”?By presenting the impact of racism on the most innocent and powerless members of society– children of color – in the form of statistics, this book aims to change attitudes and perceptions. Children have no say about where they are born or what school they attend. They have no control over whether or not they get medical treatment when they fall ill. They can’t avoid exposure if their home is in a community blighted by pollution. The questions this book poses are: What responsibility do we expect children to take for their life circumstances? Do those conditions blight their futures? If they aren’t responsible, who is? Are some in society privileged and complicit in denying people of color the advantages and protections from harm most of us take for granted? Through the cumulative effect of official statistics rather than the more usual reliance on anecdote – by taking a “show me the numbers!” approach – this book will open minds, start conversations, and even prompt readers to take action. While the numbers are official they are often hard to find because they are scattered across so many sources. Art Munin has not only done the research, but shows the reader how to locate data on racial and socio-economic disparities, and develop her or his own case or classroom project.Color by Number takes as its metaphorical point of departure the familiar children’s activity of that name. Art Munin has painstakingly researched and gathered the numbers, and has filled in the spaces to reveal the hidden picture of racism in America from the perspectives of health, the environment, the law, and education.This book is intended as a fact-based, antiracism text for diversity and social justice courses, and as a resource for diversity and social justice educators as they craft their race, racism, and White privilege curricula. Art Munin’s multidisciplinary approach – drawing on scholarly work from medicine, law, sociology, psychology, and education – provides the reader with a comprehensive way to understand the pervasiveness of racism.

Book Description
How biases, the desire for a good narrative, reliance on citation metrics, and other problems undermine confidence in modern science. Modern science is built on experimental evidence, yet scientists are often very selective in deciding what evidence to use and tend to disagree about how to interpret it. In The Matter of Facts, Gareth and Rhodri Leng explore how scientists produce and use evidence. They do so to contextualize an array of problems confronting modern science that have raised concerns about its reliability: the widespread use of inappropriate statistical tests, a shortage of replication studies, and a bias in both publishing and citing “positive” results. Before these problems can be addressed meaningfully, the authors argue, we must understand what makes science work and what leads it astray. The myth of science is that scientists constantly challenge their own thinking. But in reality, all scientists are in the business of persuading other scientists of the importance of their own ideas, and they do so by combining reason with rhetoric. Often, they look for evidence that will support their ideas, not for evidence that might contradict them; often, they present evidence in a way that makes it appear to be supportive; and often, they ignore inconvenient evidence. In a series of essays focusing on controversies, disputes, and discoveries, the authors vividly portray science as a human activity, driven by passion as well as by reason. By analyzing the fluidity of scientific concepts and the dynamic and unpredictable development of scientific fields, the authors paint a picture of modern science and the pressures it faces.

Book Description
An argument that the major metaphysical theories of facts give us no good reason to accept facts in our catalog of the world. In this book Arianna Betti argues that we have no good reason to accept facts in our catalog of the world, at least as they are described by the two major metaphysical theories of facts. She claims that neither of these theories is tenable—neither the theory according to which facts are special structured building blocks of reality nor the theory according to which facts are whatever is named by certain expressions of the form “the fact that such and such.” There is reality, and there are entities in reality that we are able to name, but, Betti contends, among these entities there are no facts. Drawing on metaphysics, the philosophy of language, and linguistics, Betti examines the main arguments in favor of and against facts of the two major sorts, which she distinguishes as compositional and propositional, giving special attention to methodological presuppositions. She criticizes compositional facts (facts as special structured building blocks of reality) and the central argument for them, Armstrong's truthmaker argument. She then criticizes propositional facts (facts as whatever is named in “the fact that” statements) and what she calls the argument from nominal reference, which draws on Quine's criterion of ontological commitment. Betti argues that metaphysicians should stop worrying about facts, and philosophers in general should stop arguing for or against entities on the basis of how we use language.
