Book Description
How do we perceive evil? How do we represent evil? In Transgression and the Aesthetics of Evil, Taran Kang examines the entanglements of aesthetics and morality. Investigating conceptions and images of evil, Kang identifies a fateful moment of transformation in the eighteenth century that continues to reverberate to the present day. Transgression, once allocated the central place in the constitution of evil, undergoes a startling revaluation in the Enlightenment and its aftermath, one that needs to be understood in relation to emergent ideas in the arts. Taran Kang engages with the writings of Edmund Burke, the Marquis de Sade, Friedrich Nietzsche, and Hannah Arendt, among others, as he questions recent calls to "de-aestheticize" evil and insists on a historically informed appreciation of evil’s aesthetic dimensions. Chapters consider the figure of the "evil genius," the paradoxical appeal of the grotesque and the disgusting, and the moral status of spectators who behold scenes of suffering and acts of transgression. In grappling with these issues, Transgression and the Aesthetics of Evil questions the feasibility and desirability of insulating the moral from the aesthetic.

Book Description
This book has been generated by the EC-funded Dedicated Road Infrastructure for Vehicle Safety in Europe DRIVE collaborative research programme. it brings together work on driver behaviour, traffic safety, and human- machine interfacing to review the state of the art in Europe in terms of systems specification, design, evaluation, and implementation for near- future vehicles.; Changes in vehicle functionality will be fundamental through the 1990's, and this book demonstrates that a purely technology driven approach is a recipe for disaster; integrated and co-ordinated multidisciplinary initiatives in complex system design are preferable and are more likely to deliver system efficiency, acceptability, and safety.; It is aimed at transport ergonomists, vehicle designers, HCI researchers, applied psychologists and cognitive ergonomists.

Book Description
Is "space" a thing, a container, an abstraction, a metaphor, or a social construct? This much is certain: space is part and parcel of the theater, of what it is and how it works. In The Play of Space, noted classicist-director Rush Rehm offers a strikingly original approach to the spatial parameters of Greek tragedy as performed in the open-air theater of Dionysus. Emphasizing the interplay between natural place and fictional setting, between the world visible to the audience and that evoked by individual tragedies, Rehm argues for an ecology of the ancient theater, one that "nests" fifth-century theatrical space within other significant social, political, and religious spaces of Athens. Drawing on the work of James J. Gibson, Kurt Lewin, and Michel Foucault, Rehm crosses a range of disciplines--classics, theater studies, cognitive psychology, archaeology and architectural history, cultural studies, and performance theory--to analyze the phenomenology of space and its transformations in the plays of Aeschylus, Sophocles, and Euripides. His discussion of Athenian theatrical and spatial practice challenges the contemporary view that space represents a "text" to be read, or constitutes a site of structural dualities (e.g., outside-inside, public-private, nature-culture). Chapters on specific tragedies explore the spatial dynamics of homecoming ("space for returns"); the opposed constraints of exile ("eremetic space" devoid of normal community); the power of bodies in extremis to transform their theatrical environment ("space and the body"); the portrayal of characters on the margin ("space and the other"); and the tragic interactions of space and temporality ("space, time, and memory"). An appendix surveys pre-Socratic thought on space and motion, related ideas of Plato and Aristotle, and, as pertinent, later views on space developed by Newton, Leibniz, Descartes, Kant, and Einstein. Eloquently written and with Greek texts deftly translated, this book yields rich new insights into our oldest surviving drama.

Book Description
Don’t fly blind. Observability gives you actionable insights into your cloud native systems—from pinpointing errors, to increasing developer productivity, to tracking compliance. Observability is the difference between an error message and an error explanation with a recipe how to resolve the error! You know exactly which service is affected, who’s responsible for its repair, and even how it can be optimized in the future. Cloud Observability in Action teaches you how to set up an observability system that learns from a cloud application’s signals, logging, and monitoring, all using free and open source tools. In Cloud Observability in Action you will learn how to: Apply observability in cloud native systems Understand observability signals, including their costs and benefits Apply good practices around instrumentation and signal collection Deliver dashboarding, alerting, and SLOs/SLIs at scale Choose the correct signal types for given roles or tasks Pick the right observability tool for any given function Communicate the benefits of observability to management A well-designed observability system provides insight into bugs and performance issues in cloud native applications. They help your development team understand the impact of code changes, measure optimizations, and track user experience. Best of all, observability can even automate your error handling so that machine users apply their own fixes—no more 3AM calls for emergency outages. About the technology Cloud native systems are made up of hundreds of moving parts. When something goes wrong, it’s not enough to know there is a problem—you need to know where it is, what it is, and how to fix it. This book takes you beyond traditional monitoring, explaining observability systems that turn application telemetry into actionable insights. About the book Cloud Observability in Action gives you the background and techniques you need to successfully introduce observability into cloud-based serverless and Kubernetes environments. In it, you’ll learn to use open standards and tools like OpenTelemetry, Prometheus, and Grafana to build your own observability system and end reliance on proprietary software. You’ll discover insights from different telemetry signals, including logs, metrics, traces, and profiles.

Book Description
Franz Liszt is most well-known for his compositions for piano and orchestra, but his influence is also strong in chamber music, choral music, and orchestral transcriptions. This new collection of essays presents a scholarly overview of all of the composer's work, providing the most comprehensive and current treatment of both his oeuvre and the immense amount of secondary literature written about it. Highly regarded critics and scholars write for both a general and academic audience, covering all of Liszt's major compositions as well as the neglected gems found among his choral and chamber works. Following an outline of the subject's life, The Liszt Companion goes on to detail Liszt's critical reception in the German press, his writings and letters, his piano and orchestral works, his neglected secular choral works, and his major organ compositions. Also explored here are his little-known chamber pieces and his songs. An exhaustive bibliography and index of works conclude the volume. This work will both elucidate aspects of Liszt's most famous work and revive interest in those pieces that deserve and require greater attention.
