To perform well in today's highly competitive world where technical skills have been advanced to an unprecedented degree, a singer must be able to handle incredible pressure within the performing arena; his or her ability to deal with this stress will often determine whether he or she will succeed. Why, then, do singers with less technical skill sometimes out-perform stars? Why do some stars suddenly stop performing? What is that mysterious factor that makes an electric performance? Consistent, competent performances do not depend solely upon superior vocal skills, nor are they a matter of luck. On the contrary, the best performances result from a combination of mental attitude, concrete performing skills, and excellent technical skills in that order. Yet most singers have never had the opportunity to acquire the essential skills that make for a successful career.Written as a self-help manual for singers at all levels of expertise, Power Performance for Singers is designed to teach performing artists, and especially singers, how to experience elite performance at their level. The skills outlined in this book will help singers use what they have, to enjoy their voices during performance, and to perform consistently to the best of their present ability.

Power and Performance: Software Analysis and Optimization is a guide to solving performance problems in modern Linux systems. Power-efficient chips are no help if the software those chips run on is inefficient. Starting with the necessary architectural background as a foundation, the book demonstrates the proper usage of performance analysis tools in order to pinpoint the cause of performance problems, and includes best practices for handling common performance issues those tools identify. - Provides expert perspective from a key member of Intel's optimization team on how processors and memory systems influence performance - Presents ideas to improve architectures running mobile, desktop, or enterprise platforms - Demonstrates best practices for designing experiments and benchmarking throughout the software lifecycle - Explains the importance of profiling and measurement to determine the source of performance issues

Performativity has emerged as a critical new idea across the humanities and social sciences, from literary and cultural studies to the study of gender and the philosophy of action. In this volume, Jeffrey Alexander demonstrates how performance can reorient our study of politics and society. Alexander develops a cultural pragmatics that shifts cultural sociology from texts to gestural meanings. Positioning social performance between ritual and strategy, he lays out the elements of social performance - from scripts to mise-en-scène, from critical mediation to audience reception - and systematically describes their tense interrelation. This is followed by a series of empirically oriented studies that demonstrate how cultural pragmatics transforms our approach to power. Alexander brings his new theory of social performance to bear on case studies that range from political to cultural power: Barack Obama's electoral campaign, American failure in the Iraqi war, the triumph of the Civil Rights Movement, terrorist violence on September 11th, public intellectuals, material icons, and social science itself. This path-breaking work by one of the world's leading social theorists will command a wide interdisciplinary readership.

Recently in the field of theatre studies there has been an increasing amount of debate and dissonance regarding the borders of its territory, its methodologies, subject matter, and scholarly perspectives. The nature of this debate could be termed "political" and, in fact, concerns "the performance of power"—the struggle over power relations embedded in texts, methodologies, and the academy itself. This striking new collection of nineteen divergent essays represents this performance of power and the way in which the recent convergence of new critical theories with historical studies has politicized the study of the theatre. Neither play text, performance, nor scholarship and teaching can safely reside any longer in the "free," politically neutral, self-signifying realm of the aesthetic. Politicizing theatrical discourse means that both the hermeneutics and the histories of theatre reveal the role of ideology and power dynamics. New strategies and concepts—and a vital new phase of awareness—appear in these illuminating essays. A variety of historical periods, from the Renaissance through the Victorian and up to the most contemporary work of the Wooster group, illustrate the ways in which contemporary strategies do not require contemporary texts and performances but can combine with historical methods and subjects to produce new theatrical discourse.

The government of Yemen, unified since 1990, remains largely incapable of controlling violence or providing goods and services to its population, but the regime continues to endure despite its fragility and peripheral location in the global political and economic order. Revealing what holds Yemen together in such tenuous circumstances, Peripheral Visions shows how citizens form national attachments even in the absence of strong state institutions. Lisa Wedeen, who spent a year and a half in Yemen observing and interviewing its residents, argues that national solidarity in such weak states tends to arise not from attachments to institutions but through both extraordinary events and the ordinary activities of everyday life. Yemenis, for example, regularly gather to chew qat, a leafy drug similar to caffeine, as they engage in wide-ranging and sometimes influential public discussions of even the most divisive political and social issues. These lively debates exemplify Wedeen’s contention that democratic, national, and pious solidarities work as ongoing, performative practices that enact and reproduce a citizenry’s shared points of reference. Ultimately, her skillful evocations of such practices shift attention away from a narrow focus on government institutions and electoral competition and toward the substantive experience of participatory politics.
