Converting STEM into STEAM Programs: Methods and Examples from and for Education (Environmental Discourses in Science Education #5)

by Michael P. Mueller Deborah J. Tippins Arthur J. Stewart

This book examines the push and pull of factors contributing to and constraining conversion of STEM (science, technology, engineering and math) education programs into STEAM (science, technology, engineering, math and arts) education programs. The chapters in this book offer thought-provoking examples, theory, and suggestions about the advantages, methods and challenges involved in making STEM to STEAM conversions, at levels ranging from K12 through graduate university programs. A large driving force for STEM-to-STEAM conversions is the emerging awareness that the scientific workforce finds itself less than ideally prepared when engaging with so-called ‘wicked problems’ – the complex suite of emerging, multifaceted issues such as global climate change, social injustice, and pandemic diseases. Dealing with these issues requires cross-disciplinary expertise and the ability to insert technical and scientific understanding effectively into areas of public planning and policy. The different models and possibilities for STEAM, as the next phase of the STEM revolution, laid out in this book will promote research and further our understanding of STEAM as a forward-thinking approach to education.Gillian Roehrig, STEM Education, University of Minnesota, USAThe ideal teacher sees opportunities for integrating ideas from multiple disciplines into every lesson. This book offers many worthwhile suggestions on how to do that deliberately and systematicallyGeorge DeBoer, Project 2061 of the American Association for the Advancement of Science, USAFor the last several years, calls for expanding STEM education have grown, but so too have concerns about technocratic approaches to STEM. This volume challenges the community to consider broader views on STEM by focusing on the place of arts education within this movement. The chapters offer much needed, new perspectives on the (re)integration of the arts and sciencesTroy Sadler, School of Education, University of North Carolina, USA

Convictions Without Truth: The Incompatibility of Science and Law (Routledge Frontiers of Criminal Justice)

by Robert Schehr

Convictions Without Truth sets out to determine whether and to what extent science and law may coexist in an institutional relationship that truthfully generates individualization through application of forensic testimony for charges relating to violations of criminal law. In the first two chapters, readers are exposed to contemporary unscientific forensic practices as juxtaposed to the evidentiary standard announced by the United States Supreme Court in Daubert v. Merrill Dow Pharmaceuticals, as well as scientific requirements for validity and reliability of expert witness testimony. The remaining chapters provide an explanation for retention of existing, though faulty, forensic practices by way of analysis of path dependency, the fixation of belief, and neuro and cognitive psychology. Through immanent critique and unmasking, the book deconstructs prevailing forensic practices through application of existing published documentation. The final chapter addresses the fixation of belief from the perspective of neuropsychology and cognitive psychology. Readers will gain an understanding of the current concerns relating to application of contemporary forensic practices ; current case law and federal rules guiding the introduction of expert witness testimony; and why it is that despite widely recognized concerns raised from within and outside of the criminal legal system, application of unscientific forensic practices continues., The book also shows how the criminal legal system is experiencing a paradigm shift due to dialectical juxtaposition of existing unscientific forensic practices with contemporary science. Readers are shown that because of its continued reliance upon unscientific forensic practices, the criminal legal system reveals its hegemonic commitment to social control through its willingness to accept "satisfying" as opposed to "truthful" results that generate wrongful convictions. Convictions Without Truth will be of particular interest to students, academics, and practitioners working within the criminal legal field. It will also appeal to those wanting to know more about forensics and criminal law.

Convolutional Neural Networks for Medical Image Processing Applications

by Şaban Öztürk

The rise in living standards increases the expectation of people in almost every field. At the forefront is health. Over the past few centuries, there have been major developments in healthcare. Medical device technology and developments in artificial intelligence (AI) are among the most important ones.

AI algorithms enable the fast and early evaluation of images from medical devices to maximize the benefits. While developments in the field of AI were quickly adapted to the field of health, in some cases this contributed to the formation of innovative artificial intelligence algorithms. Today, the most effective artificial intelligence method is accepted as deep learning. Convolutional neural network (CNN) architectures are deep learning algorithms used for image processing. This book contains applications of CNN methods. The content is quite extensive, including the application of different CNN methods to various medical image processing problems. Readers will be able to analyze the effects of CNN methods presented in the book in medical applications.

Convulsed States: Earthquakes, Prophecy, and the Remaking of Early America

by Jonathan Todd Hancock

The New Madrid earthquakes of 1811–12 were the strongest temblors in the North American interior in at least the past five centuries. From the Great Plains to the Atlantic Coast and from the Great Lakes to the Gulf of Mexico, a broad cast of thinkers struggled to explain these seemingly unprecedented natural phenomena. They summoned a range of traditions of inquiry into the natural world and drew connections among signs of environmental, spiritual, and political disorder on the cusp of the War of 1812. Drawn from extensive archival research, Convulsed States probes their interpretations to offer insights into revivalism, nation remaking, and the relationship between religious and political authority across Native nations and the United States in the early nineteenth century. With a compelling narrative and rigorous comparative analysis, Jonathan Todd Hancock uses the earthquakes to bridge historical fields and shed new light on this pivotal era of nation remaking. Through varied peoples' efforts to come to grips with the New Madrid earthquakes, Hancock reframes early nineteenth-century North America as a site where all of its inhabitants wrestled with fundamental human questions amid prophecies, political reinventions, and war.

Cooke and Wheatstone: And the Invention of the Electric Telegraph (Routledge Library Editions: History & Philosophy of Science)

by Geoffrey Hubbard

Originally published in 1965. Charles Wheatstone collaborated with William Cooke in the invention and early exploitation of the Electric Telegraph. This was the first long distance, faster-than-a-horse messenger. This volume gives an account of the earlier work on which the English invention was founded, and the curious route by which it came to England. It discusses the way in which two such antagonistic men were driven into collaboration and sets out the history of the early telegraph lines, including work on the London and Birmingham Railway and the Great Western Railway.

Cool: How the Brain's Hidden Quest for Cool Drives Our Economy and Shapes Our World

by Steven Quartz Anette Asp

A bold argument that our "quest for cool" shapes modern culture and the global economyLike it or not, we live in an age of conspicuous consumption. In a world of brand names, many of us judge ourselves and others by the products we own. Teenagers broadcast their brand allegiances over social media. Tourists flock to Rodeo Drive to have their pictures taken in front of luxury stores. Soccer moms switch from minivans to SUVs to hybrids, while hip beer connoisseurs flaunt their knack for distinguishing a Kölsch from a pilsner. How did this pervasive desire for "cool" emerge, and why is it so powerful today that it is a prime driver of the global economy? In Cool, the neuroscientist and philosopher Steven Quartz and the political scientist Anette Asp bring together the latest findings in brain science, economics, and evolutionary biology to form a provocative theory of consumerism, revealing how the brain's "social calculator" and an instinct to rebel are the crucial missing links in understanding the motivations behind our spending habits. Applying their theory to everything from grocery shopping to the near-religious devotion of Harley-Davidson fans, Quartz and Asp explore how the brain's ancient decision-making machinery guides consumer choice. Using these revolutionary insights, they show how we use products to advertise ourselves to others in an often unconscious pursuit of social esteem. Surprising at every turn, Cool will change the way you think about money, status, desire, and choice.

The Cooling

by Lowell Ponte

Are we entering a new ice age? Many scientists think so. Many others say that the climate is becoming unstable, and that this instability is a critical threat to world food production. Earth's climate has been cooling rapidly for the past three decades, and this has already caused drought and famine in major areas of the world. In the time it takes you to read this book, at least a thousand people will have starved to death because of the impact climatic instability already has had on food production. And The Cooling has barely begun. Few questions are as urgent today as those concerning climate change and what may be done about it. Dr. Cesare Emiliani, a "paleoclimatologist" at the University of Miami, says: "Is Earth's climate changing? Should governments try to modify climate? In dealing with these controversial issues, Lowell Ponte has written a remarkably thorough, far-ranging, balanced, and scientifically accurate book-the best popular book I have read on both these questions. I recommend THE COOLING to anyone who likes to think, and who cares about the planet we share."

Cooling Electrons in Nanoelectronic Devices by On-Chip Demagnetisation (Springer Theses)

by Alexander Thomas Jones

This thesis demonstrates that an ultralow temperature refrigeration technique called "demagnetisation refrigeration" can be miniaturised and incorporated onto millimeter-sized chips to cool nanoelectronic circuits, devices and materials. Until recently, the lowest temperature ever reached in such systems was around 4 millikelvin. Here, a temperature of 1.2mK is reported in a nanoelectronic device. The thesis introduces the idea that on-chip demagnetization refrigeration can be used to cool a wide variety of nanostructures and devices to microkelvin temperatures. This brings the exciting possibility of discovering new physics, such as exotic electronic phases, in an unexplored regime and the potential to improve the performance of existing applications, including solid-state quantum technologies. Since the first demonstration of on-chip demagnetization refrigeration, described here, the technique has been taken up by other research groups around the world. The lowest on-chip temperature is currently 0.4mK. Work is now underway to adapt the technique to cool other materials and devices, ultimately leading to a platform to study nanoscale materials, devices and circuits at microkelvin temperatures.

Cooperation and Collective Action: Archaeological Perspectives

by David M. Carballo

Past archaeological literature on cooperation theory has emphasized competition's role in cultural evolution. As a result, bottom-up possibilities for group cooperation have been under theorized in favor of models stressing top-down leadership, while evidence from a range of disciplines has demonstrated humans to effectively sustain cooperative undertakings through a number of social norms and institutions. Cooperation and Collective Action is the first volume to focus on the use of archaeological evidence to understand cooperation and collective action. Disentangling the motivations and institutions that foster group cooperation among competitive individuals remains one of the few great conundrums within evolutionary theory. The breadth and material focus of archaeology provide a much needed complement to existing research on cooperation and collective action, which thus far has relied largely on game-theoretic modeling, surveys of college students from affluent countries, brief ethnographic experiments, and limited historic cases. In Cooperation and Collective Action, diverse case studies address the evolution of the emergence of norms, institutions, and symbols of complex societies through the last 10,000 years. This book is an important contribution to the literature on cooperation in human societies that will appeal to archaeologists and other scholars interested in cooperation research.

Cooperation and Conflict: The Interaction of Opposites in Shaping Social Behavior

by Walter Wilczynski Sarah F. Brosnan

Understanding the interaction between cooperation and conflict in establishing effective social behaviour is a fundamental challenge facing societies. Reflecting the breadth of current research in this area, this volume brings together experts from biology to political science to examine the cooperation–conflict interface at multiple levels, from genes to human societies. Exploring both the exciting new directions and the biggest challenges in their fields, the authors focus on identifying commonalities across species and disciplines to help understand what features are shared broadly and what are limited to specific contexts. Each chapter is written to be accessible to students and researchers from interdisciplinary backgrounds, with text boxes explaining terminology and concepts that may not be familiar across disciplinary boundaries, while being a valuable resource to experts in their fields.

Cooperation and Its Evolution

by Kim Sterelny Brett Calcott Ben Fraser Richard Joyce

This collection reports on the latest research on an increasingly pivotal issue for evolutionary biology: cooperation. The chapters are written from a variety of disciplinary perspectives and utilize research tools that range from empirical survey to conceptual modeling, reflecting the rich diversity of work in the field. They explore a wide taxonomic range, concentrating on bacteria, social insects, and, especially, humans. Part I ("Agents and Environments") investigates the connections of social cooperation in social organizations to the conditions that make cooperation profitable and stable, focusing on the interactions of agent, population, and environment. Part II ("Agents and Mechanisms") focuses on how proximate mechanisms emerge and operate in the evolutionary process and how they shape evolutionary trajectories. Throughout the book, certain themes emerge that demonstrate the ubiquity of questions regarding cooperation in evolutionary biology: the generation and division of the profits of cooperation; transitions in individuality; levels of selection, from gene to organism; and the "human cooperation explosion" that makes our own social behavior particularly puzzling from an evolutionary perspective.

Cooperative Breeding in Vertebrates

by Koenig, Walter D. den Ridder, Stef Walter D. Koenig Stef Den Ridder

Cooperative breeders are species in which individuals beyond a pair assist in the production of young in a single brood or litter. Although relatively rare, cooperative breeding is widespread taxonomically and continues to pose challenges to our understanding of the evolution of cooperation and altruistic behavior. Bringing together long-term studies of cooperatively breeding birds, mammals, and fishes, this volume provides a synthesis of current studies in the field. The chapters are organised by individual studies of particular species or (in the case of mole-rats) two closely related cooperatively breeding species. Each focuses not only on describing behavior and ecology but also on testing evolutionary hypotheses for the form and function of the diverse and extraordinary cooperative breeding lifestyles that have been discovered. This unique and comprehensive text will be of interest to graduate students and researchers of behavioral ecology and the evolution of cooperation.
