This volume of essays focuses on how individuals living in the late tenth through fifteenth centuries engaged with the authorizing culture of the Anglo-Saxons. Drawing from a reservoir of undertreated early English documents and texts, each contributor shows how individual poets, ecclesiasts, legists, and institutions claimed Anglo-Saxon predecessors for rhetorical purposes in response to social, cultural, and linguistic change. Contributors trouble simple definitions of identity and period, exploring how medieval authors looked to earlier periods of history to define social identities and make claims for their present moment based on the political fiction of an imagined community of a single, distinct nation unified in identity by descent and religion. Contributors are Cynthia Turner Camp, Irina Dumitrescu, Jay Paul Gates, Erin Michelle Goeres, Mary Kate Hurley, Maren Clegg Hyer, Nicole Marafioti, Brian O'Camb, Kathleen Smith, Carla María Thomas, Larissa Tracy, and Eric Weiskott.

This book reviews the chemical, regulatory, and physiological mechanisms of protein arginine and lysine methyltransferases, as well as nucleic acid methylations and methylating enzymes. Protein and nucleic acid methylation play key and diverse roles in cellular signalling and regulating macromolecular cell functions.Protein arginine and lysine methyltransferases are the predominant enzymes that catalyse S-adenosylmethionine (SAM)-dependent methylation of protein substrates. These enzymes catalyse a nucleophilic substitution of a methyl group to an arginine or lysine side chain nitrogen (N) atom. Cells also have additional protein methyltransferases, which target other amino acids in peptidyl side chains or N-termini and C-termini, such as glutamate, glutamine, and histidine. All these protein methyltransferases use a similar mechanism. In contrast, nucleic acids (DNA and RNA) are substrates for methylating enzymes, which employ various chemical mechanisms to methylatenucleosides at nitrogen (N), oxygen (O), and carbon (C) atoms. This book illustrates how, thanks to there ability to expand their repertoire of functions to the modified substrates, protein and nucleic acid methylation processes play a key role in cells.

Named a Best Book of 2019 by NPR “How might we mitigate losses caused by shortsightedness? Bina Venkataraman, a former climate adviser to the Obama administration, brings a storyteller's eye to this question.... She is also deeply informed about the relevant science.” —The New York Times Book Review A trailblazing exploration of how we can plan better for the future: our own, our families', and our society's. Instant gratification is the norm today—in our lives, our culture, our economy, and our politics. Many of us have forgotten (if we ever learned) how to make smart decisions for the long run. Whether it comes to our finances, our health, our communities, or our planet, it's easy to avoid thinking ahead. The consequences of this immediacy are stark: Deadly outbreaks spread because leaders failed to act on early warning signs. Companies that fail to invest stagnate and fall behind. Hurricanes and wildfires turn deadly for communities that could have taken more precaution. Today more than ever, all of us need to know how we can make better long-term decisions in our lives, businesses, and society. Bina Venkataraman sees the way forward. A journalist and former adviser in the Obama White House, she helped communities and businesses prepare for climate change, and she learned firsthand why people don't think ahead—and what can be done to change that. In The Optimist's Telescope, she draws from stories she has reported around the world and new research in biology, psychology, and economics to explain how we can make decisions that benefit us over time. With examples from ancient Pompeii to modern-day Fukushima, she dispels the myth that human nature is impossibly reckless and highlights the surprising practices each of us can adopt in our own lives—and the ones we must fight for as a society. The result is a book brimming with the ideas and insights all of us need in order to forge a better future.

The book presents research that contributes to the development of intelligent dialog systems to simplify diverse aspects of everyday life, such as medical diagnosis and entertainment. Covering major thematic areas: machine learning and artificial neural networks; algorithms and models; and social and biometric data for applications in human–computer interfaces, it discusses processing of audio-visual signals for the detection of user-perceived states, the latest scientific discoveries in processing verbal (lexicon, syntax, and pragmatics), auditory (voice, intonation, vocal expressions) and visual signals (gestures, body language, facial expressions), as well as algorithms for detecting communication disorders, remote health-status monitoring, sentiment and affect analysis, social behaviors and engagement. Further, it examines neural and machine learning algorithms for the implementation of advanced telecommunication systems, communication with people with special needs, emotionmodulation by computer contents, advanced sensors for tracking changes in real-life and automatic systems, as well as the development of advanced human–computer interfaces. The book does not focus on solving a particular problem, but instead describes the results of research that has positive effects in different fields and applications.

Biology is a critical application area for engineering analysis and design, and students in engineering programs as well as ecologists and environmentalists must be well-versed in the fundamentals of biology as they relate to their field. Biology for Engineers, Second Edition is an introductory text that minimizes unnecessary memorization of connections and classifications and instead emphasizes concepts, technology, and the utilization of living things. Whether students are headed toward a bio-related engineering degree or one of the more traditional majors, biology is so important that all engineering students should know how living things work and act. Emphasizing the ever-present interactions between a biological unit and its physical, chemical, and biological environments, the book provides ample instruction on the basics of physics, chemistry, mathematics, and engineering through a systems approach. It brings together all the concepts one needs to understand the role of biology in modern technology.Classroom-tested at the University of Maryland, this comprehensive text introduces concepts and terminology needed to understand more advanced biology literature. Filled with practical detailed examples, the book presents: Presents scientific principles relevant to biology that all engineers, ecologists and environmentalists must know A discussion of biological responses from the perspective of a broad range of fields such as psychology, human factors, genetics, plant and animal physiology, imaging, control systems, actuary, and medicine Includes end of chapter questions to test comprehension Provides updated material to reflect the latest research developments such as CRISPR. Introduces over 150 interesting application examples, incorporating a number of different engineering disciplines. Ties biological systems properties and behaviors to foundational sciences such as engineering sciences, chemistry, etc.

An evolutionary psychologist traces the roots of political divisions back to our primate ancestors and male-dominated social hierarchies.Through the lens of evolutionary science, this book offers a novel perspective on why we hold our political ideas, and why they are so often in conflict. Drawing on examples from across the animal kingdom, clinical psychologist Hector A. Garcia reveals how even the most complex political processes can be influenced by our basic drives to survive and reproduce--including the policies we back, whether we are liberal or conservative, and whether we are inspired or repelled by the words of a president. The author demonstrates how our political orientations derive from an ancestral history of violent male competition, surprisingly influencing how we respond to issues as wide-ranging as affirmative action, women's rights, social welfare, abortion, foreign policy, and even global warming. Critically, the author shows us how our instinctive political tribalism can keep us from achieving stable, functioning societies, and offers solutions for rising above our ancestral past.

This book provides essential information on the status quo and changing profile of Hirschsprung's disease and allied disorders. Hirschsprung's disease is a common cause of neonatal intestinal obstruction and one of the most important and most fascinating diseases in pediatric surgery throughout the world. Currently, the diagnosis and treatment of Hirschsprung's disease and allied disorders are in a state of constant development. Written by expert pediatric surgeons, Hirschsprung's Disease and the Allied Disorders presents state-of-the-art information, such as new genetic evidence, and historical operative techniques that were less invasive and resulted in fewer follow-up operations. It offers a highly informative guide that will greatly benefit all readers engaged in pediatric medicine, pediatric surgeons, and the medical staff of NICUs around the globe.

This book is the first to provide balanced examination of both pediatric liver disease and liver transplantation – two topics that are inherently related, given that most chronic liver disorders eventually require organ replacement. The different forms of liver disease encountered in the pediatric age group are first discussed in a series of disease-specific chapters that have a reader-friendly, uniform structure covering pathophysiology, diagnostic and treatment algorithms, clinical cases, and transition to adult care. Key topics in the field of liver transplantation are then addressed. Examples include indications and contraindications, surgical techniques and complications, immunosuppression, in pediatric liver transplantation, acute and chronic rejection and allograft dysfunction, and CMV and EBV infection in transplant recipients, long-term graft injury and tolerance. A section on pediatric hepatology across the world includes chapters presenting the features and management of pediatric liver disease in South-America, Africa and Asia. A closing section considers what the future holds for pediatric liver disease and its management, including novel genetic testing, cell therapy and gene therapy. Pediatric Hepatology and Liver Transplantation will be of value for a range of practitioners, from residents making their first approach to pediatric liver disease through to specialists working in transplantation centers.

In this politically and democratically urgent collection, George Yancy and contributors argue that more than ever, we are in need of classrooms that function'dangerously'—that is, classrooms where people are not afraid to engage in critical discussions that call into question difficult political times. Collectively they demonstrate the ways activist authors and scholars must be prepared to engage in risk and vulnerability as a defense of our democratic right to practice forms of pedagogical transgression. Ideal for scholars and students of critical pedagogy, philosophy of education, and political theory, this collection delineates the necessity of critical consciousness through education, and provides ways of speaking back against authoritarian control of imaginative and critical capacities.

Recent world-wide political developments have persuaded many people that we are again living in what Hannah Arendt called “dark times.” Jackson's response to this age of uncertainty is to remind us how much experience falls outside the concepts and categories we habitually deploy in rendering life manageable and intelligible. Drawing on such critical thinkers as Hannah Arendt, Theodor Adorno, Walter Benjamin, and Karl Jaspers, whose work was profoundly influenced by the catastrophes that overwhelmed the world in the middle of the last century, Jackson explores the transformative and redemptive power of marginalized voices in the contemporary conversation of humankind.

This book analyzes why we believe what we believe about politics, and how the answer affects the way democracy functions. It does so by applying social evolution theory to the relationship between the news media and politics, using the United States as its primary example. This includes a critical review and integration of the insights of a broad array of research, from evolutionary theory and political psychology to the political economy of media. The result is an empirically driven political theory on the media's role in democracy: what role it currently plays, what role it should play, and how it can be reshaped to be more appropriate for its structural role in democracy.

A breakthrough work in neuroscience and an incisive corrective to a long history of damaging pseudo-science, finally debunking the myth that there is a biological distinction between male and female brains. For decades if not centuries, science has backed up society's simple dictum that men and women are hardwired differently, that the world is divided by two different kinds of brains—male and female. However, new research in neuroimaging suggests that this is little more than “neurotrash.” In this powerfully argued work, acclaimed professor of neuroimaging, Gina Rippon, finally challenges this damaging myth by showing how the science community has engendered bias and stereotype by rewarding studies that show difference rather than sameness. Drawing on cutting edge research in neuroscience and psychology, Rippon presents the latest evidence which finally proves that brains are like mosaics comprised of both male and female components, and that they remain plastic, adapting throughout the course of a person's life. Discernable gender identities, she asserts, are shaped by society where scientific misconceptions continue to be wielded and perpetuated to the detriment of our children, our own lives, and our culture.

In this book, 30 contributions provide a comprehensive overview of theories and findings from research on political attitudes and political behaviour, subdivided into the fields of ‘political communication', ‘political attitudes', ‘political participation', ‘voting behaviour'and ‘methods'.

This book offers a wide-ranging examination of acts of ‘virtual embodiment'in performance/gaming/applied contexts that abstract an immersant's sense of physical selfhood by instating a virtual body, body-part or computer-generated avatar. Emergent ‘immersive'practices in an increasingly expanding and cross-disciplinary field are coinciding with a wealth of new scientific knowledge in body-ownership and self-attribution. A growing understanding of the way a body constructs its sense of selfhood is intersecting with the historically persistent desire to make an onto-relational link between the body that ‘knows'an experience and bodies that cannot know without occupying their unique point of view. The author argues that the desire to empathize with another's ineffable bodily experiences is finding new expression in contexts of particular urgency. For example, patients wishing to communicate their complex physical experiences to their extended networks of support in healthcare, orcommunities placing policymakers ‘inside'vulnerable, marginalized or disenfranchised virtual bodies in an attempt to prompt personal change. This book is intended for students, academics and practitioner-researchers studying or working in the related fields of immersive theatre/art-making, arts-science and VR in applied performance practices.

The gap between the rich and the poor has grown dramatically in the United States and is now at its widest since at least the early 1900s. While by most measures the economy has been improving, soaring cost of living and stagnant wages have done little to assuage economic anxieties. Conditions like these seem designed to produce a generation-defining intervention to balance the economic scales and enhance opportunities for those at the middle and bottom of the country's economic ladder—but we have seen nothing of the sort. Nathan J. Kelly argues that a key reason for this is that rising concentrations of wealth create a politics that makes reducing economic inequality more difficult. Kelly convincingly shows that, when a small fraction of the people control most of the economic resources, they also hold a disproportionate amount of political power, hurtling us toward a self-perpetuating plutocracy, or an “inequality trap.” Among other things, the rich support a broad political campaign that convinces voters that policies to reduce inequality are unwise and not in the average voter's interest, regardless of the real economic impact. They also take advantage of interest groups they generously support to influence Congress and the president, as well as state governments, in ways that stop or slow down reform. One of the key implications of this book is that social policies designed to combat inequality should work hand-in-hand with political reforms that enhance democratic governance and efforts to fight racism, and a coordinated effort on all of these fronts will be needed to reverse the decades-long trend.

Il volume'La disciplina penale in materia d'imposte dirette e I.V.A.', frutto di un'attenta ricognizione dei principali orientamenti della dottrina e della giurisprudenza, anche sovranazionale, affronta in maniera sistematica l'analisi della disciplina penale in materia di imposte dirette e di I.V.A., tenendo conto anche della più recente evoluzione legislativa in materia, introdotta dal d.lgs. n. 158 del 2015, di cui fornisce anche originali spunti interpretativi.

In the United States, the early years of the war on terror were marked by the primacy of affects like fear and insecurity. These aligned neatly with the state's drive toward intensive securitization and an aggressive foreign policy. But for the broader citizenry, such affects were tolerable at best and unbearable at worst; they were not sustainable. Figuring Violence catalogs the affects that define the latter stages of this war and the imaginative work that underpins them. These affects—apprehension, affection, admiration, gratitude, pity, and righteous anger—are far more subtle and durable than their predecessors, rendering them deeply compatible with the ambitions of a state embroiling itself in a perpetual and unwinnable war.Surveying the cultural landscape of this sprawling conflict, Figuring Violence reveals the varied mechanisms by which these affects have been militarized. Rebecca Adelman tracks their convergences around six types of beings: civilian children, military children, military spouses, veterans with PTSD and TBI, Guantánamo detainees, and military dogs. All of these groups have become preferred objects of sentiment in wartime public culture, but they also have in common their status as political subjects who are partially or fully unknowable. They become visible to outsiders through a range of mediated and imaginative practices that are ostensibly motivated by concern or compassion. However, these practices actually function to reduce these beings to abstracted figures, silencing their political subjectivities and obscuring their suffering. As a result, they are erased and rendered hypervisible at once. Figuring Violence demonstrates that this dynamic ultimately propagates the very militarism that begets their victimization.

The publication of ‘Over the Mountains and Far Away: Studies in Near Eastern history and archaeology presented to Mirjo Salvini on the occasion of his 80th birthday'was initiated by the Institute of Archaeology and Ethnography, National Academy of Sciences of Armenia, the International Association of Mediterranean and Oriental Studies (Rome, Italy) and the Association for Near Eastern and Caucasian Studies (Yerevan, Armenia) as a tribute to the career of Professor Mirjo Salvini on the occasion his 80th birthday. It is composed of 62 papers written by his colleagues and students from Italy, Germany, France, Spain, Poland, the Netherlands, Denmark, Austria, Great Britain, Russian Federation, Israel, Turkey, Islamic Republic of Iran, Georgia, United States and Armenia. The contributions presented here cover numerous topics, a wide geographical area and a long chronological period. However, most of the contributions deal with research in the fields of Urartian and Hittite Studies, the topics that attracted Prof. Salvini during his long and fruitful career most.

The motivation behind this important volume is to weave together two distinct, but we think complementary, traditions – the philosophical engagement with race/whiteness and Buddhist philosophy – in order to explore the ways in which these traditions can inform, correct, and improve each other. This exciting and critically informed volume will be the first of its kind to bring together essays that explicitly connect these two traditions and will mark a major step both in understanding race and whiteness (with the help of Buddhist philosophy) and in understanding Buddhist philosophy (with the help of philosophy of race and theorizations of whiteness). We expand upon a small, but growing, body of work that applies Buddhist philosophical analyses to whiteness and racial injustice in contemporary U.S. culture. Buddhist philosophy has much to contribute to furthering our understanding of whiteness and racial identity, the mechanisms that create and maintain white supremacy, and the possibility of dismantling white supremacy. We are interested both in the possible insights that Buddhist metaphysical, epistemological, and ethical analyses can bring to understanding race and whiteness, as well as the potential limitations of such Buddhist-inspired approaches.In their chapters, contributors draw on Buddhist philosophical and contemplative traditions to offer fresh, insightful, and powerful perspectives on issues regarding racial identity and whiteness, including such themes as cultural appropriation, mechanisms of racial injustice and racial justice, phenomenology of racial oppression, epistemologies of racial ignorance, liberatory practices with regard to racism, Womanism, and the intersections of gender-based, raced-based, and sexuality-based oppressions. Authors make use of both contemporary and ancient Buddhist philosophical and contemplative traditions. These include various Asian traditions, including Theravada, Mahayana, Tantra, and Zen, as well as comparatively new American Buddhist traditions.

Child and Adolescent Psychology provides an accessible and thorough introduction to human development by integrating insights from typical and atypical development. This integration cements understanding since the same processes are involved. Knowledge about atypical development informs the understanding of typical development, and knowledge about typical development is a necessary basis for understanding atypical development and working with children with disorders.Based on international research, and informed by biological, social and cultural perspectives, the book provides explanations of developmental phenomena, with a focus on how children and adolescents at different age levels actually think, feel and act. Following a structure by topic, with chronological developments within each chapter, von Tetzchner presents and contrasts the major theoretical ideas in developmental psychology and discusses their implications for different aspects of development. He also integrates information about sensory, physical and cognitive disabilities and the main emotional and behavioral disorders of childhood and adolescence, and the developmental consequences of these disabilities and disorders.Child and Adolescent Psychology is accompanied by online resources for lecturers and students to enhance the book, including essay questions for each chapter, Powerpoint slides and multiple-choice questions. The book and companion website will prove invaluable to developmental psychology students.

The third edition of this successful title presents current research and commercial uses of controlled atmosphere storage and modified atmosphere packaging of fresh fruit and vegetables to provide a comprehensive and up-to-date overview. New and developed technologies for the transportation and storage of horticultural products are essential to ensure that produce reaches consumers in the best possible condition, and have the potential to reduce the postharvest use of chemicals, reduce losses and maintain nutritional quality and organoleptic characteristics. Covering the increasingly used science and technology of preserving the freshness of fruit and vegetables in all aspects of their postharvest life, this book puts the subject in the context of its history and current practices, in addition to future prospects. The new edition: - Explores the large volume of research that is continuously being published on the topic. - Reviews and evaluates the adaptation and improvement of commercial technologies. - Considers the effects of techniques and technologies on flavour, quality and physiology, in addition to the damage inflicted by pests, diseases and disorders. - Contains 5 new chapters covering genetics and CA storage, dynamic CA storage, hyperbaric storage, hypobaric storage and fruit ripening. Fully revised and presented in full colour throughout, this book is a readily accessible resource for researchers, scientists, growers, students and industry personnel.

La fiscalità delle operazioni straordinarie costituisce area di particolare complessità per una serie di ragioni. Innanzi tutto l'incertezza relativa al suo perimetro posto che non esiste una sua definizione normativa. Ancora, la circostanza che, pur all'interno dello stesso tributo, l'area coinvolge soggetti di diversa natura (enti, societari e non, persone fisiche, soggetti fiscalmente residenti e non) e standard contabili differenti (vuoi i principi contabili nazionali, vuoi gli IAS/IFRS 2) con conseguente sua possibile variabilità (p.e. la fiscalità legata al bilancio d'esercizio o, secondo la nomenclatura IAS/IFRS, bilancio separato). Si consideri peraltro che le operazioni straordinarie sono interessate dalla fiscalità non solo in quanto tali, ossia come operazioni, ma anche in quanto contemplate in atti negoziali che ne prevedono e ne disciplinano l'esecuzione; abbiamo dunque una fiscalità dell'operazione in sé considerata, variabile in funzione del soggetto e/o del tributo considerato (p.e. società e socio) ed una fiscalità dell'atto che contempla l'operazione straordinaria. Non solo, ma l'atto che contempla e disciplina tra le parti l'operazione straordinaria può contenere pattuizioni (p.e. price adjustment, indemnity, gross up, earn out, clausole di garanzia, ecc.) il cui trattamento fiscale coinvolge, in una prospettiva per così dire dinamica, che guardi all'esecuzione delle pattuizioni medesime, anche tributi diversi da quelli c.d. d'atto (p.e. le imposte sui redditi) generandosi in tal modo l'intrecciarsi della fiscalità dell'operazione con quella dell'atto e della sua esecuzione. Come si vedrà scorrendo i singoli contributi di questo volume, le ragioni testé illustrate spiegano il perché la fiscalità della categoria, valutata nel suo complesso, risulti priva di sistematicità, dispersa in una serie di discipline, il cui studio unitario – confermato del resto dalle numerose pubblicazioni dedicate all'argomento – si deve vuoi ad alcuni regimi comuni all'interno della disciplina di singoli tributi, vuoi alla fungibilità delle operazioni considerate, vuoi infine all'attenzione che, in una prospettiva anti-elusiva, il legislatore tradizionalmente riserva a molte delle operazioni che la compongono considerandole un terreno fertile per l'ottenimento di vantaggi fiscali indebiti. Insomma, la straordinarietà non esprime affatto il riconoscimento di un regime tributario speciale, neppure ove si consideri la disciplina del singolo comparto impositivo

Knowledge-based systems, fully integrated with software, have become essential enablers for both science and commerce. But current software methodologies, tools and techniques are not robust or reliable enough for the demands of a constantly changing and evolving market, and many promising approaches have proved to be no more than case-oriented methods that are not fully automated. This book presents the proceedings of the 17th international conference on New Trends in Intelligent Software Methodology, Tools and Techniques (SoMeT18) held in Granada, Spain, 26-28 September 2018. The SoMeT conferences provide a forum for the exchange of ideas and experience, foster new directions in software development methodologies and related tools and techniques, and focus on exploring innovations, controversies, and the current challenges facing the software engineering community. The 80 selected papers included here are divided into 13 chapters, and cover subjects as diverse as intelligent software systems; medical informatics and bioinformatics; artificial intelligence techniques; social learning software and sentiment analysis; cognitive systems and neural analytics; and security, among other things. Offering a state-of-the-art overview of methodologies, tools and techniques, this book will be of interest to all those whose work involves the development or application of software.

The first philosophical monograph on the ethics of memory manipulation (MM),'Forget Me Not: The Neuroethical Case Against Memory Manipulation'contends that any attempt to directly and intentionally erase episodic memories poses a grave threat to the human condition that cannot be justified within a normative moral calculus. Grounding its thesis in four evidential effects – namely, (i) MM disintegrates autobiographical memory, (ii) the disintegration of autobiographical memory degenerates emotional rationality, (iii) the degeneration of emotional rationality decays narrative identity, and (iv) the decay of narrative identity disables one to seek, identify, and act on the good – DePergola argues that MM cannot be justified as a morally licit practice insofar as it disables one to seek, identify, and act on the good. A landmark achievement in the field of neuroethics, this book is a welcome addition to both the scholarly and professional community in philosophical and clinical bioethics.

This unique reference explores the processes and nuances of human habits through social psychology and behavioral lenses. It provides a robust definition and theoretical framework for habit as well as up-to-date information on habit measurement, addressing such questions as which mechanisms are involved in habitual action and whether people can report accurately on their own habits. Specialized chapters pay close attention to how habits can be modified, as well as widely varying manifestations of habitual thoughts and behaviors, including the mechanisms of drug addiction and recovery, the repetitive characteristics of autism, and the unwitting habits of health professionals that may impede patient care. And across these pages, contributors show the potential for using the processes of maladaptive habits to replace them with positive and health-promoting ones. Throughout this volume attention is also paid to the practice of conducting habit research. Among the topics covered: Habit mechanisms and behavioral complexity.Complexities and controversies of physical activity habit.Habit discontinuities as vehicles for behavior change.Habits in depression: understanding and intervention.A critical review of habit theory of drug dependence.Questions about the automaticity of habitual behaviors. The Psychology of Habit will interest psychologists across a wide spectrum of domains: habit researchers in broader areas of social and health psychology, professionals working in (sub)clinical areas, interested scholars in marketing, consumer research, communication, and education, and public policymakers dealing with questions of behavioral change in the areas of health, sustainability, and/or education.

This book endeavours to present an analysis of the current knowledge of the structure properties and possible functions of histones. The broad scope of this topic prevents the discussion of certain individual aspects in any detail. For this purpose, some of the more specialised review articles should be consulted. However, the present volume will contribute to a more general understanding of histone biochemistry and will provide stimulation, as well as source references, to the student of the cell nucleus and its functions.

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.

Dieses Buch entwickelt eine kritische Theorie der Wirtschaft, die zum Ausgangspunkt nimmt, dass Wirtschaftswissenschaft nicht nur ihren Gegenstand beschreibt und analysiert, sondern sozialontologisch konstituiert. Im Mittelpunkt steht das Konzept der Performativität. Kritik bedeutet, dass reflexive Strukturen der Performativität offengelegt und hinterfragt werden, um neue Optionen ökonomischen Handelns und der Wirtschaftspolitik zu erschließen. Das Buch behandelt die wichtigsten Bereiche der Wirtschaftswissenschaft, beginnend mit der kritischen Theorie des Individuums, die Ergebnisse der Verhaltens- und Neuroökonomik auf einer evolutionstheoretischen Grundlage systematisiert. Die kritische Theorie der Wirtschaft thematisiert das Verhältnis zwischen Ökologie und Ökonomie, und sie stellt sich in die Tradition Karl Polanyis mit der Frage, wie weit die Wirtschaft ihre eigenen Grundlagen schaffen oder gefährden kann. Ein Kernelement ist eine Theorie des Geldes, die dessen Performativität systematisch anerkennt. Aufbauend auf modernen wissenschaftstheoretischen Konzeptionen wird eine Synthese von Institutionen- und Makroökonomik vorgeschlagen, die auf das Versagen der Wirtschaftswissenschaft angesichts der jüngsten Finanzkrise reagiert. Die normative kritische Theorie setzt schließlich an der Beobachtung an, dass Marktmechanismen endogen Macht erzeugen. Das Buch wagt abschließend, eine'reale Utopie der Sozialen Marktwirtschaft'zu entwerfen, die durch radikale institutionelle Reformen neue Formen einer gerechten und nachhaltigen Wirtschaft performiert.

Why do people spend so much time thinking about the future, imagining scenarios that may never occur, and making (often unrealistic) predictions? This volume brings together leading researchers from multiple psychological subdisciplines to explore the central role of future-thinking in human behavior across the lifespan. It presents cutting-edge work on the mechanisms involved in visualizing, predicting, and planning for the future. Implications are explored for such important domains as well-being and mental health, academic and job performance, ethical decision making, and financial behavior. Throughout, chapters highlight effective self-regulation strategies that help people pursue and realize their short- and long-term goals.

In the wake of an extremely contentious U.S. presidential election that touched upon several hot-button issues including the right to marry and the legacy of the Civil Rights Movement, debate has erupted regarding the language people use to describe both political issues and groups of people. This book takes a look at the widening gap between those who believe political correctness is an unnecessary affectation and those who believe a greater good can be achieved with increased sensitivity in how we talk to, and about, each other. Through analyzing a range of viewpoints, students are encouraged to form their own opinions on this important topic.

Maintenance of the information embedded in the genomic DNA sequence is essential for life. DNA polymerases play pivotal roles in the complex processes that maintain genetic integrity. Besides their tasks in vivo, DNA polymerases are the workhorses in numerous biotechnology applications such as the polymerase chain reaction (PCR), cDNA cloning, next generation sequencing, nucleic acids based diagnostics and in techniques to analyze ancient and otherwise damaged DNA (e.g. for forensic applications). Moreover, some diseases are related to DNA polymerase defects and chemotherapy through inhibition of DNA polymerases is used to fight HIV, Herpes and Hepatitis B and C infections. This book focuses on (i) biology of DNA polymerases, (ii) medical aspects of DNA polymerases and (iii) biotechnological applications of DNA polymerases. It is intended for a wide audience from basic scientists, to diagnostic laboratories, to companies and to clinicians, who seek a better understanding and the practical use of these fascinating enzymes.

Why does inequality have such a hold on American society and public policy? And what can we, as citizens, do about it? Inequality in America takes an in-depth look at race, class and gender-based inequality, across a wide range of issues from housing and education to crime, employment and health. Caliendo explores how individual attitudes can affect public opinion and lawmakers'policy solutions. He also illustrates how these policies result in systemic barriers to advancement that often then contribute to individual perceptions. This cycle of disadvantage and advantage can be difficult-though not impossible-to break.'Representing'and'What Can I Do?'feature boxes throughout the book highlight key public figures who have worked to combat inequality and encourage students to take action to do the same. The second edition has been thoroughly revised to include the most current data and to cover recent issues and events like the 2016 elections and the Black Lives Matter movement. It now also includes a brand-new chapter on crime and criminal justice and an expanded discussion of immigration. Concise and accessible, Inequality in America paves the way for students to think critically about the attitudes, behaviors and structures of inequality.

The second edition of The Oxford Handbook of Personality and Social Psychology beautifully captures the history, current status, and future prospects of personality and social psychology. Building on the successes and strengths of the first edition, this second edition of the Handbook combines the two fields of personality and social psychology into a single, integrated volume, offering readers a unique and generative agenda for psychology. Over their history, personality and social psychology have had varying relationships with each other-sometimes highly overlapping and intertwined, other times contrasting and competing. Edited by Kay Deaux and Mark Snyder, this Handbook is dedicated to the proposition that personality and social psychology are best viewed in conjunction with one another and that the synergy to be gained from considering links between the two fields can do much to move both areas of research forward in order to better enrich our collective understanding of human nature. Contributors to this Handbook not only offer readers fascinating examples of work that cross the boundaries of personality and social psychology, but present their work in such a way that thinks deeply about the ways in which a unified social-personality perspective can provide us with a greater understanding of the phenomena that concern psychological investigators. The chapters of this Handbook effortlessly weave together work from both disciplines, not only in areas of longstanding concern, but also in newly emerging fields of inquiry, addressing both distinctive contributions and common ground. In so doing, they offer compelling evidence for the power and the potential of an integrated approach to personality and social psychology today.

For courses in Introduction to Communication A five-principles approach that helps students build practical communication skills Communication: Principles for a Lifetime was designed to address the biggest challenge when teaching Introduction to Communication: how to present the variety of fundamental theory and skills without overwhelming learners. By organizing the text around five key principles of communication, authors Steven Beebe, Susan Beebe, and Diana Ivy help students to see the interplay among communication concepts, skills, and contexts. The 7th Edition has been updated with new coverage of social media communication strategies.

The potential of tomb mosaics as an academic resource has often been underestimated and consequently they have only been partially analysed not only in Italy but also throughout the Western Mediterranean. This work is intended to shed a new light on these finds, which are often incomplete, lost, or little studied. The first part of the book presents the history of previous studies on the subject and briefly explains the structure of the corpus. The corpus, in turn, is organised according to current Italian administrative regions, specifically: Sardegna, Sicilia, Puglia, Campania, Lazio, Marche, and Friuli Venezia Giulia. Every region is then further divided following current provinces and municipalities. This work does not aim to present merely a compilation of data in a catalogue; thus the second part of the book focuses specifically on tomb mosaics found in the Italic peninsula and major islands, and provides information on their geographic distribution, dating, typology, place of discovery and iconography, and considers the potential identification of individual workshops. The purpose of the book is to bring tomb mosaics to greater consideration, since they have not survived in academic literature to the same extent as did their rich villa or domus counterparts. This work does not therefore aspire to be a complete analysis of the subject, but rather a starting point which can be both useful and a stimulus for future studies. ITALIAN DESCRIPTION: Il mosaico funerario è una particolare tipologia musiva spesso sottovalutata e poco studiata. Le origini sono da ricercarsi, probabilmente, nell'antica regione della Bizacena, attuale Tunisia, a partire dagli ultimi decenni del III secolo d.C. Nel IV secolo iniziò l'esportazione dei cartoni musivi funerari nel resto del Mediterraneo occidentale, raggiungendo l'Italia e la Spagna; in entrambi i casi però il mosaico funerario non riscosse particolare successo. La richiesta maggiore di questo nuovo monumento funerario avveniva da parte dei cristiani, e solo in minima parte dai pagani. In questo libro si cerca di fare ordine sui mosaici funerari presenti nell'odierno territorio italiano, catalogando tutte le evidenze musive, sia oggigiorno scomparse che ancora in situ, per cercare di delineare un'analisi sul fenomeno che ha, in maniera seppur ridotta, investito la Penisola italiana e le sue Isole maggiori. Infatti le testimonianze musive si concentrano in zone dove particolari condizioni hanno permesso la loro messa in posa. La prima parte è dedicata al repertorio dei sessanta mosaici funerari dell'attuale Italia, ognuno catalogato secondo una scheda pensata e studiata per rendere più agevole possibile la consultazione. La seconda parte è invece incentrata sullo studio d'insieme del fenomeno dei mosaici funerari in Italia, nella quale si cerca di fare chiarezza e dare dei punti fermi su questa categoria di mosaici. L'analisi conclusiva cerca di spiegare il perché in Italia, pur essendoci condizioni apparentemente favorevoli alla produzione delle coperture tombali musive, non si siano trovati che poche testimonianze musive funerarie se paragonate a quelle ritrovate nel Nord Africa e in special maniera in Bizacena.

While every constitution includes a provision over the right to equal protection of the laws, perhaps with different terminology, this book interprets this right in a new way. Theories of the right to equal protection of the laws as the right to anti-subordination are the most influential theories on the theory suggested by Drymiotou. Elena Drymiotou suggests understanding the right to equal protection of the laws in terms of belonging. She goes on to identify certain criteria and she offers a general theory of the Right to Democratic Belonging. This book uses political theory, constitutional provisions and case law to suggest this new theory of the right to equal protection of the laws; the theory of the Right to Equal Belonging in a Democratic Society or in other words, the Right to Democratic Belonging.Human Rights and Equal Belonging in a Democratic Society is the starting point of a more comprehensive theory of the right to democratic belonging. It will be of interest both to students at an advanced level, academics and reflective practitioners. It addresses the topics with regard to human rights and equality and will be of interest to researchers, academics, policymakers and students in the fields of human rights law, constitutional law and legal theory.

This book focuses on numerical simulations of manufacturing processes, discussing the use of numerical simulation techniques for design and analysis of the components and the manufacturing systems. Experimental studies on manufacturing processes are costly, time consuming and limited to the facilities available. Numerical simulations can help study the process at a faster rate and for a wide range of process conditions. They also provide good prediction accuracy and deeper insights into the process. The simulation models do not require any pre-simulation, experimental or analytical results, making them highly suitable and widely used for the reliable prediction of process outcomes. The book is based on selected proceedings of AIMTDR 2016. The chapters discuss topics relating to various simulation techniques, such as computational fluid dynamics, heat flow, thermo-mechanical analysis, molecular dynamics, multibody dynamic analysis, and operational modal analysis. These simulation techniques are used to: 1) design the components, 2) to investigate the effect of critical process parameters on the process outcome, 3) to explore the physics of the process, 4) to analyse the feasibility of the process or design, and 5) to optimize the process. A wide range of advanced manufacturing processes are covered, including friction stir welding, electro-discharge machining, electro-chemical machining, magnetic pulse welding, milling with MQL (minimum quantity lubrication), electromagnetic cladding, abrasive flow machining, incremental sheet forming, ultrasonic assisted turning, TIG welding, and laser sintering. This book will be useful to researchers and professional engineers alike.

Heroes are often admired for their ability to act without having'one thought too many,'as Bernard Williams put it. Likewise, the unhesitating decisions of masterful athletes and artists are part of their fascination. Examples like these make clear that spontaneity can represent an ideal. However, recent literature in empirical psychology has shown how vulnerable our spontaneous inclinations can be to bias, shortsightedness, and irrationality. How can we make sense of these different roles that spontaneity plays in our lives? The central contention of this book is that understanding these two faces of spontaneity-its virtues and its vices-requires understanding the'implicit mind.'In turn, understanding the implicit mind requires considering three sets of questions. The first set focuses on the architecture of the implicit mind itself. What kinds of mental states make up the implicit mind? Are both'virtue'and'vice'cases of spontaneity products of one and the same mental system? What kind of cognitive structure do these states have, if so? The second set of questions focuses on the relationship between the implicit mind and the self. How should we relate to our spontaneous inclinations and dispositions? Are they'ours,'in the sense that they reflect on our character or identity? Are we responsible for them? The third set focuses on the ethics of spontaneity. What can research on self-regulation teach us about how to improve the ethics of our implicit minds? How can we enjoy the virtues of spontaneity without succumbing to its vices? Bringing together several streams of philosophical and psychological research, The Implicit Mind is the first book to offer a philosophical account of implicit attitudes.

How to live well and the search for meaning have long been of intense concern to humans, perhaps because Homo sapiens is the only species aware of its own mortality. In the last few decades, empirical psychology made a major contribution to this quest. This book surveys groundbreaking work by leading international researchers, demonstrating that social psychology is the core discipline for understanding well-being and the search for meaning. Basic conceptual and theoretical principles are discussed, drawing on philosophy, evolutionary theory and psychology, followed by a review of the role of purposeful, motivated activity and self-control in achieving life satisfaction. The role of emotional and cognitive processes and the influence of social, interpersonal and cultural factors in promoting a happy and meaningful life are discussed. The book will be of interest to students, practitioners and researchers in the behavioral and social sciences, as well as to laypersons for whom improving the quality of human life and understanding the principles of well-being are of interest.

A bold philosophical investigation into technology and the limits of the human A daring, original work of philosophical speculation, Neurotechnology and the End of Finitude mounts a sustained investigation into the possibility that human beings may technologically overcome the transcendental limits of possible experience and envisages what such a transition would look like. Focusing on emergent neurotechnologies, which establish a direct channel of communication between brain and machine, Michael Haworth argues that such technologies intervene at the border between interiority and exteriority, offering the promise of immediacy and the possibility of the mind directly affecting the outside world or even other minds. Through detailed, targeted readings of Kant, Freud, Heidegger, Croce, Jung, and Derrida, Haworth explores the effect of this transformation on human creativity and our relationships with others. He pursues these questions across four distinct but interrelated spheres: the act of artistic creation and the potential for a technologically enabled coincidence of idea and object; the possibility of humanity achieving the infinite creativity that Kant attributed only to God; the relationship between the psyche and the external world in Freudian psychoanalysis and Jungian analytical psychology; and the viability and impact of techno-telepathic communication. Addressing readers interested in contemporary continental philosophy and philosophy of technology, media and communications, and science and technology studies, Neurotechnology and the End of Finitude critically envisions a plausible posthuman future.

This text provides a comprehensive and balanced coverage of health psychology from an Australian and international perspective. With coverage across all mainstream health topics with analyses and evaluations of contemporary issues, the authors present issues then introduce theory and research evidence to assess relevant interventions. In addition to the original European focus, the authors believed a comprehensive Australian-focused textbook was required. The vast rural and regional areas, indigenous populations, and the high immigrant population, all present particular challenges to our health system that are important to understand and address. The overall aim of this text is to provide a comprehensive Australian textbook which is firmly grounded in both theory and empirical evidence, with sufficient breadth of material for introductory students, but also sufficient research depth to benefit final-year students or those conducting a health psychology project.

The Homeric Simile in Comparative Perspectives: Oral Traditions from Saudi Arabia to Indonesia investigates both the construction of the Homeric simile and the performance of Homeric poetry from neglected comparative perspectives, offering a revealing exploration of what made the epics such powerful examples of verbal artistry. Divided into two parts, the volume first considers similes in five modern-day oral poetries - Rajasthani epic, South Sumatran epic, Kyrgyz epic, Bosniac epic, and Najdi lyric poems from Saudi Arabia - and studies successful performances by still other verbal artists, such as Egyptian singers of epic, Turkish minstrels, and Chinese storytellers. By applying these findings to the Homeric epics, the second part presents a new take on how the Homeric poets put together their similes and alters our understanding of how the poets displayed their competence as performers of verbal art and interacted with their poetic peers and predecessors. Engaging intensively with a diverse array of scholarship from outside the field of classical studies, from folkloristics to cognitive linguistics, this truly interdisciplinary volume transforms how we view not only a central feature of Homeric poetry but also the very nature of Homeric performance.
