This volume covers the development of modern music from World War I to the present. Specific musical responses can be identified from the prevailing social, economic and political circumstances. Since World War II musical languages have tended to converge, with developments in technology and communications. Robert P. Morgan is the author of "Twentieth Century Music", and co-editor of "Alban Berg: Historical and Analytical Perspectives".

We would like to take this opportunity to thank all of those individ uals who helped us assemble this text, including the people of Lockheed Sanders and Nestor, Inc., whose encouragement and support were greatly appreciated. In addition, we would like to thank the members of the Lab oratory for Engineering Man-Machine Systems (LEMS) and the Center for Neural Science at Brown University for their frequent and helpful discussions on a number of topics discussed in this text.

Much controversy surrounds Schenker's mature theory and its attempt to explain musical pitch motion. Becoming Heinrich Schenker brings a new perspective to Schenker's theoretical work, showing that ideas characteristic of his mature theory, although in many respects fundamentally different, developed logically out of his earlier ideas. Robert P. Morgan provides an introduction to Schenker's mature theory and traces its development through all of his major publications, considering each in detail and with numerous music examples. Morgan also explores the relationship between Schenker's theory and his troubled ideology, which crucially influenced the evolution of his ideas and was heavily dependent upon both the empirical and idealist strains of contemporary German philosophical thought. Relying where possible on quotations from Schenker's own words, this book offers a balanced approach to his theory and a unique overview of this central music figure, generally considered to be the most prominent music theorist of the twentieth century.

In regenerative medicine, tissue engineers largely rely on destructive and time-consuming techniques that do not allow in situ and spatial monitoring of tissue growth. Furthermore, once the therapy is implanted in the patient, clinicians are often unable to monitor what is happening in the body. To tackle these barriers, optical techniques have been developed to image and characterize many tissue properties, fabricate tissue engineering scaffolds, and characterize the properties of the scaffolds. Optical Techniques in Regenerative Medicine illustrates how to use optical imaging techniques and instrumentation for the fabrication, assessment, and longitudinal monitoring of regenerative medicine therapies. The book covers optical coherence tomography, acousto-optic imaging, Raman spectroscopy, machine vision, bioluminescence, second harmonic generation microscopy, multi-photon microscopy, coherent anti-Stokes Raman scattering, fluorescence spectroscopy, and light scattering spectroscopy. Each chapter provides an overview of a particular technique, its advantages and limitations in terms of structural and functional information, and examples of applications in regenerative medicine. The future evolution of regenerative medicine from academic research to viable clinical alternatives to conventional treatments is dependent on the development of non-destructive analytical techniques that can elucidate the stages of tissue development both in vitro and in vivo as well as track the fate of cells following injection. This practical book demonstrates the vital role of optical techniques in the dynamic field of regenerative medicine. It guides regenerative medicine researchers toward finding the most appropriate technique for their applications and helps biophotonics researchers see where their technologies can be applied.

Robert P. Morgan is one of a small number of music theorists writing in English who treat music theory, and in particular Schenkerian theory, as part of general intellectual life. Morgan's writings are renowned within the field of music scholarship: he is the author of the well-known Norton volume Twentieth-Century Music, and of additional books relating to Schenkerian and other theory, analysis and society. This volume of Morgan's previously published essays encompasses a broad range of issues, including historical and social issues and is of importance to anyone concerned with modern Western music. His specially written introduction treats his writings as a whole but also provides additional material relating to the articles included in this volume.

This text is an effort to summarize and synthesize the existing research dealing with the influence of physical activity on mental health, as well as the potential mechanisms underlying psychological effects. Contributions from some of the leading experts in the field deal with mental health through prevention, exercise prescription, exercise adherence, drug therapy and exercise, the influence of physical activity on depression, anxiety, and self-esteem, and the paradoxical effects of excessive amounts of exercise.

We are pleased to present the Proceedings of the Second International Conference on Computational Fluid Dynamics held at the University of Sydney, Australia, from July 15 to 19, 2002. The conference was a productive meeting of scientists, mathematicians and engineers involved in the computation of fluid flow. Keynote lectures were presented in the areas of optimisation, algorithms, turbulence and bio-fluid mechanics. Two hundred and fifty abstracts from many countries were received for con sideration. The executive committee, consisting of A. Lerat, M. Napolitano, J.J. Chattot, N. Satofuka and myself, were responsible for the selection of papers. Each of the members had a separate subcommittee to carry out the evaluation. One hundred and seventy papers were selected of which one hundred and fifty two were presented at the conference. All papers that appear in the proceedings have been peer reviewed by a panel of experts (with a minimum of two for every paper) before publication. The conference was attended by 160 delegates with a minimum of late with drawals. The informal and friendly atmosphere provided by the university sur roundings was highly appreciated, and the technical aspects of the conference were stimulating. It is appropriate here to thank Alain Lerat, the retiring secretary of the international scientific committee of the conference. We also wish to welcome J. J. Chattot who is the incoming secretary."

Jennifer can't believe it. Just married and pregnant, she discovers that her husband has been meeting Brad for sex. When confronted, Tom doesn't deny it, but he insists it's just "a thing" and he isn't gay. Elsewhere, John's wife, Karen, discovers that her husband likes to watch gay porn. John doesn't understand his wife's reaction. Why does she care what he watches if he's not unfaithful? In couple's therapy, Karen and Jennifer raise the same questions: Does this mean my husband is gay? Can my marriage survive? These and other stories illustrate the difficulties inherent when a wife or girlfriend finds out her man has had or wants to have sexual contact with other men. But many times, the man is not gay or even bisexual. Of course, some men with gay sexual interests are gay men in a process of self-discovery; they are "coming out." These desires may only reflect a different side of a man's sexuality or some response to childhood trauma or experiences they have not fully processed. Here Joe Kort and Alexander P. Morgan make the distinction between gay men and "straight men with gay interests" clearer to women who want to know how they can overcome these revelations. The authors explain the many reasons why straight men may be drawn to gay sex; how to tell whether a man is gay, straight, or bisexual; and what the various options are for these couples, who can often go on to have very fulfilling marriages. Is My Husband Gay, Straight or Bi? is intended to help couples understand how male sexuality can express itself in ways that may be difficult to understand. Many marriages have been hurriedly terminated when couples (and their therapists) have lacked the information they needed to understand their current situations. This book provides the clarity, describes the choices, and (in many cases) offers hope for relationships and marriages that have been brushed off as doomed.

Much progress has been made in achieving the ambitious goals that Congress established in 1972 in the Clean Water Act (CWA) to restore and maintain the chemical, physical, and biological integrity of the nations waters. However, long-standing problems persist, and new problems have emerged. Water quality problems are diverse, ranging from pollution runoff from farms and ranches, city streets, and other diffuse or nonpoint sources, to toxic substances discharged from factories and sewage treatment plants. Since the early 2000s, increased oil and gas production across the nation has resulted in a corresponding increase in wastewater that must be managed, reused, or disposed of properly. In particular, the hydraulic fracturing process has also raised concerns about potential effects to human health and the environment, including the potential contamination of underground drinking water sources by injecting wastewater associated with the production of oil and gas.
