Release from Prison - European Policy and Practice (Hardcover): Nicola Padfield, Dirk van Zyl Smit, Frieder Dunkel Release from Prison - European Policy and Practice (Hardcover)
Nicola Padfield, Dirk van Zyl Smit, Frieder Dunkel
R4,948 Discovery Miles 49 480 Ships in 10 - 15 working days

Release from prison is matter of increasing interest throughout Europe. On the one hand, arguments about the need to reduce prison numbers, as well the consistent findings that prisoners can be integrated into society more effectively if they are subject to a period of supervision in the community, have made early release policies attractive to governments and to academic commentators. On the other hand, there are concerns that early release may not be applied fairly to all prisoners.

This book aims to meet the need for comparative information on release from prison across Europe and explores some of the key themes and issues. The body of the book focuses on country perspectives, providing an invaluable survey of the situation in a number of European countries.

The introductory and concluding chapters place the comparative material in a broader perspective. They explain how release policy is related to wider questions about justice and fairness in prison-related decision-making and the changing place of imprisonment in European society.

This book focuses on opera house acoustics based on subjective preference theory; it targets researchers in acoustics and vision who are working in physics, psychology and brain physiology. This book helps readers to understand any subjective attributes in relation to objective parameters based on the powerful and workable model of the auditory system. It is reconfirmed here that the well-known Helmholtz theory, which was based on a peripheral model of the auditory system, may not well describe pitch, timbre and duration as well as the spatial sensations described in this book, nor overall responses such as subjective preference of sound fields and the annoyance of environmental noise.

Timbre: Acoustics, Perception, and Cognition (Hardcover, 1st ed. 2019): Kai Siedenburg, Charalampos Saitis, Stephen McAdams,... Timbre: Acoustics, Perception, and Cognition (Hardcover, 1st ed. 2019)

R4,749 Discovery Miles 47 490 Ships in 18 - 22 working days

Roughly defined as any property other than pitch, duration, and loudness that allows two sounds to be distinguished, timbre is a foundational aspect of hearing. The remarkable ability of humans to recognize sound sources and events (e.g., glass breaking, a friend's voice, a tone from a piano) stems primarily from a capacity to perceive and process differences in the timbre of sounds. Timbre raises many important issues in psychology and the cognitive sciences, musical acoustics, speech processing, medical engineering, and artificial intelligence. Current research on timbre perception unfolds along three main fronts: On the one hand, researchers explore the principal perceptual processes that orchestrate timbre processing, such as the structure of its perceptual representation, sound categorization and recognition, memory for timbre, and its ability to elicit rich semantic associations, as well as the underlying neural mechanisms. On the other hand, timbre is studied as part of specific scenarios, including the perception of the human voice, as a structuring force in music, as perceived with cochlear implants, and through its role in affecting sound quality and sound design. Finally, computational acoustic models are sought through prediction of psychophysical data, physiologically inspired representations, and audio analysis-synthesis techniques. Along these three scientific fronts, significant breakthroughs have been achieved during the last decade. This volume will be the first book dedicated to a comprehensive and authoritative presentation of timbre perception and cognition research and the acoustic modeling of timbre. The volume will serve as a natural complement to the SHAR volumes on the basic auditory parameters of Pitch edited by Plack, Oxenham, Popper, and Fay, and Loudness by Florentine, Popper, and Fay. Moreover, through the integration of complementary scientific methods ranging from signal processing to brain imaging, the book has the potential to leverage new interdisciplinary synergies in hearing science. For these reasons, the volume will be exceptionally valuable to various subfields of hearing science, including cognitive auditory neuroscience, psychoacoustics, music perception and cognition, but may even exert significant influence on fields such as musical acoustics, music information retrieval, and acoustic signal processing. It is expected that the volume will have broad appeal to psychologists, neuroscientists, and acousticians involved in research on auditory perception and cognition. Specifically, this book will have a strong impact on hearing researchers with interest in timbre and will serve as the key publication and up-to-date reference on timbre for graduate students, postdoctoral researchers, as well as established scholars.

Recording Studio Design (Paperback, 4th edition): Philip Newell Recording Studio Design (Paperback, 4th edition)
Philip Newell
R3,797 Discovery Miles 37 970 Ships in 9 - 17 working days

Recording Studio Design, Fourth Edition explains the key principles of successful studio design and construction using straightforward language and the use of practical examples appreciated by readers of previous editions. Updated to reflect new industry standards, this fourth edition addresses improvements in cinema sound, with specific attention paid to B-chain electroacoustic response and calibration. Using over 50 years' experience, author Philip Newell provides detail on the practical aspects of recording in various environments, not only exploring the complex issues relating to the acoustics but also providing real-world solutions. While the book contains detailed discussions about performing rooms, control rooms, and mobile studios, concepts of the infrastructures are also discussed, because no studio can perform optimally unless the technical and human requirements are adequately provided for. In this new edition, sound for cinema provides a platform for highlighting many, wider electroacoustic topics in a way that is relatively easy to visualise. The way in which sound and vision interact is an important aspect of many modern multimedia formats. The new edition includes: A new Chapter 22 that will thoroughly reflect recently published SMPTE investigations which will drastically impact standards for cinema sound; The inclusion of new academic research and its practical applications; An entire new illustrated chapter on room construction principles; and The consolidation of ideas which were only emerging when the earlier editions were published.

Organic LEDs (OLEDs) in mobile displays have been in large-scale production for over a decade, and OLED-based televisions are rapidly gaining traction in the marketplace. OLEDs are on the verge of entering the solid-state lighting market in a big way. The OLED technology gives higher color purity and is more efficient than any of the competing technologies. When produced at scale, OLEDs are also economical. A key limitation in the development of OLEDs was the efficient conversion of all of the electrical energy put into the device into light. Until the late 1990s, the maximum efficiency of OLEDs was limited to 25% (photons/electrons), but this limitation was removed and OLEDs with 100% efficiency were reported in the early 2000s. This advance in OLED technology was driven by the author of this book. He and his collaborators developed electrophosphorescence, which is essential in reaching the 100% efficiency that is now commonplace in commercial devices.
