Performance Models and Risk Management in Communications Systems
by Berc Rustem Nalân Gülpınar Peter G. HarrisonThis volume covers recent developments in the design, operation, and management of mobile telecommunication and computer systems. Uncertainty regarding loading and system parameters leads to challenging optimization and robustness issues. Stochastic modeling combined with optimization theory ensures the optimum end-to-end performance of telecommunication or computer network systems. In view of the diverse design options possible, supporting models have many adjustable parameters and choosing the best set for a particular performance objective is delicate and time-consuming. An optimization based approach determines the optimal possible allocation for these parameters. Researchers and graduate students working at the interface of telecommunications and operations research will benefit from this book. Due to the practical approach, this book will also serve as a reference tool for scientists and engineers in telecommunication and computer networks who depend upon optimization.

This book defines the interdisciplinary field of performance studies as it has evolved over the past four decades at the intersection of academic scholarship and artistic and activist practices. It discusses performance as an important means of communicating and of understanding the world, highlighting its intersections with critical theory and arguing for the importance of performance in the study of human behaviour and social practices. Complete with a helpful glossary and bibliography, as well as suggestions for further reading, this book is an ideal starting point for those studying performance studies as well as for general readers with an interest in the subject.
The Performative Presidency
by Jason L. MastThe Performative Presidency brings together literatures describing presidential leadership strategies, public understandings of citizenship, and news production and media technologies between the presidencies of Theodore Roosevelt and Bill Clinton, and details how the relations between these spheres have changed over time. Jason L. Mast demonstrates how interactions between leaders, publics, and media are organized in a theatrical way, and argues that mass mediated plot formation and character development play an increasing role in structuring the political arena. He shows politics as a process of ongoing performances staged by motivated political actors, mediated by critics, and interpreted by audiences, in the context of a deeply rooted, widely shared system of collective representations. The interdisciplinary framework of this book brings together a semiotic theory of culture with concepts from the burgeoning field of performance studies.
Performed Ethnography and Communication: Improvisation and Embodied Experience
by D Soyini MadisonPerformed Ethnography and Communication explores the relationships between these three key terms, addressing the impact of ethnography and communication on the cutting edge of performance studies. Ranging from digital performance, improvisation and the body, to fieldwork and staged collaboration, this volume is divided into two main sections: "Embodied technique and practice," which addresses improvisation, devised theatre-making, and body work to consider what makes bodies move, sound, behave, mean, or appear differently, and the effects of these differences on performance; "Oral history and personal narrative performance," which is concerned with the ways personal stories and histories might be transformed into public events, looking at questions of perspective, ownership, and reception. Including specific historical and theoretical case studies, exercises and activities, and practical applications for improvisation, ethnography, and devised and digital performance, Performed Ethnography and Communication represents an invaluable resource for today’s student of performance studies, communication studies or cultural studies.
The Performer in Mass Media: Connecting with Television and Online Audiences

Its no-nonsense approach offers readers practical advice about on-camera performance, including key aspects of voice, movement, communication and appearance. It gives them a foundation for working in the studio, in the field and in front of an audience; it is ideal for media performers of any type, including those who work as reporters, company spokespersons, or community advocates.Recommendations include how to properly position oneself for a shot, how to improve articulation, how to deal with stress and how to best perform online. "Try-It-Out" exercises help readers put what they have learned into practice and prepare to be on camera. Key terms are bolded in the chapters and are collected in a book-end Glossary for easy reference.
Performing Artists and Precarity: Work in the Contemporary Entertainment Industries
by Philip Hancock Melissa TylerThis open access book focuses on the distinctive experiences of freelance and self-employed live performers in the UK’s live entertainment industries It provides an in-depth account of their working lives during COVID-19, showing how their experiences of the pandemic provide insight into the different types of precarity shaping what it means to be a live performer. A growing body of academic research has focused on the meaning, experience, and nature of precarity for those working in the cultural and creative sector, highlighting the problem of socio-economic precarity. This book demonstrates how a constant struggle for recognition also shapes the contours and lived experiences of live performance work. It emphasizes how, combined with affective and socio-economic forms of precarity, this recognitive precarity creates a distinctive and challenging set of working conditions. Drawing on original data generated through a national survey of self-employed and freelance performers across the live entertainment industries, combined with insights derived from a series of in-depth semi-structured interviews, this book presents an empirically rich insight into the struggles and opportunities presented by the multiple forms of precarity that the pandemic brought to the fore. It gives voice to a precarious workforce that remains integral to one of the UK’s most economically buoyant sectors but whose experiences are often marginalized in academic research, and in policy and practice. It will, therefore, offer a unique insight for both students and scholars of work and employment, and for those working in the cultural and creative sector, into the distinctive nature of work as a freelance or self-employed live performer.
Performing Feeling in Cultures of Memory
by Bryoni TrezisePerforming Feeling in Cultures of Memory brings memory studies into conversation with a focus on feelings as cultural actors. It charts a series of memory sites that range from canonical museums and memorials, to practices enabled by the virtual terrain of Second Life, popular 'trauma TV' programs and radical theatre practice.
Performing Kamishibai: An Emerging New Literacy for a Global Audience (Routledge Research in Education)
by Tara McGowanKamishibai (paper-theater), a Japanese picture-storytelling medium, is gaining global interest as we move from a text-based culture to one that emphasizes multiple semiotic systems and performance. This is the first volume to explore the potential of kamishibai as a dynamic "new" interactive medium for teaching multimodal communication and shows how synchronizing oral, visual and gestural modes develops students’ awareness of all modes of communication as potential resources in their learning. By examining the multiple modes involved in kamishibai through actual student performances over several venues, this volume overturns commonly held expectations about literacy in the classroom and provides a critical perspective on assumptions about other media. It offers much-needed information about a medium that is attracting interest from educators, academics and artists worldwide.
Performing Organizational Paradoxes (Routledge Studies in Communication, Organization, and Organizing)
by Gail T. Fairhurst Linda L. PutnamPerforming Organizational Paradoxes takes a constitutive, process approach to organizational paradoxes. It underscores the performative nature of paradox through underlying dialectical tensions, its sociomaterial foundations, and power features that bring paradoxes to life, sustain them, and enable their transformation. The book first situates a constitutive approach in the extant organizational paradox literature, by broadening the constitutive approach and addressing the many debates and inaccuracies around it. For the novice, several early chapters devote themselves to considering how paradoxical tensions present themselves, invite responses, and interrelate through their organizing outcomes. For the advanced, latter chapters consider the ubiquity of power and paradox, how bodies escape the quarantine of their paradox narratives, how inventive category work can resist power-imbued paradoxes, and an agenda for future research that challenges scholars to do more on the process side of paradox. Filling an important gap in the existing literature, this book will be a key resource for scholars and students in the fields of communication, management, educational administration, organizational psychology and any other fields that study organizations.
Performing the News: Identity, Authority, and the Myth of Neutrality
by Elia PowersPerforming the News: Identity, Authority, and the Myth of Neutrality explores how journalists from historically marginalized groups have long felt pressure to conform when performing for audiences. Many speak with a flat, “neutral” accent, modify their delivery to hide distinctive vocal attributes, dress conventionally to appeal to the “average” viewer, and maintain a consistent appearance to avoid unwanted attention. Their aim is what author Elia Powers refers to as performance neutrality—presentation that is deemed unobjectionable, reveals little about journalists’ social identity, and supposedly does not detract from their message. Increasingly, journalists are challenging restrictive, purportedly neutral forms of self-presentation. This book argues that performance neutrality is a myth that reinforces the status quo, limits on-air diversity, and hinders efforts to make newsrooms more inclusive. Through in-depth interviews with journalists in broadcasting and podcasting, and those who shape their performance, the author suggests ways to make journalism more inclusive and representative of diverse audiences.
Performing the Past: A Study of Israeli Settlement Museums (Everyday Communication Series)
by Tamar KatrielA nostalgic interest in the past is a well-recognized feature of fast-changing, contemporary societies. It finds its expression in a variety of history-making practices of which the establishment of local heritage museums is a major manifestation in many parts of the world today. Katriel develops a communication-centered perspective on the study of heritage museums and -- by extension -- other tourist sites, highlighting the role of discourse in these institutionalized, yet vernacular contexts of cultural production, social legitimation, and identity formation. Descriptive and critical in orientation, this book combines a close analysis of museum discourse with an exploration of such larger issues as: * the socio-cultural role of museums as arenas for the production of collective memory, * the ideological and performative constraints that shape museum presentations, * the interfacing of verbal and visual codes of communication in the context of material displays, * the dialectical interplay of the local and the global in contemporary life, and * the interpenetration of the personal and the communal in vernacular processes of narrative production. Of interest to scholars in communication, linguistics, anthropology, history, museum studies, tourism, intercultural communication, middle eastern studies, or those with interests in narratives, material culture, and ethnography.
Performing Trauma in Central Africa: Shadows of Empire (African Expressive Cultures)
by Laura Edmondson“An outstanding addition to the literature on theatre and performance in situations of conflict and post-conflict.” —New Theatre QuarterlyWhat are the stakes of cultural production in a time of war? How is artistic expression prone to manipulation by the state and international humanitarian organizations? In the charged political terrain of post-genocide Rwanda, post-civil war Uganda, and recent violence in the Democratic Republic of Congo, Laura Edmondson explores performance through the lens of empire.Instead of celebrating theatre productions as expression of cultural agency and resilience, Edmondson traces their humanitarian imperatives to a place where global narratives of violence take precedence over local traditions and audiences. Working at the intersection of performance and trauma, Edmondson reveals how artists and cultural workers manipulate narratives in the shadow of empire and how empire, in turn, infiltrates creative capacities.
The Perilous Public Square: Structural Threats to Free Expression Today
by David E. PozenAmericans of all political persuasions fear that “free speech” is under attack. This may seem strange at a time when legal protections for free expression remain strong and overt government censorship minimal. Yet a range of political, economic, social, and technological developments have raised profound challenges for how we manage speech. New threats to political discourse are mounting—from the rise of authoritarian populism and national security secrecy to the decline of print journalism and public trust in experts to the “fake news,” trolling, and increasingly subtle modes of surveillance made possible by digital technologies.The Perilous Public Square brings together leading thinkers to identify and investigate today’s multifaceted threats to free expression. They go beyond the campus and the courthouse to pinpoint key structural changes in the means of mass communication and forms of global capitalism. Beginning with Tim Wu’s inquiry into whether the First Amendment is obsolete, Matthew Connelly, Jack Goldsmith, Kate Klonick, Frederick Schauer, Olivier Sylvain, and Heather Whitney explore ways to address these dangers and preserve the essential features of a healthy democracy. Their conversations with other leading thinkers, including Danielle Keats Citron, Jelani Cobb, Frank Pasquale, Geoffrey R. Stone, Rebecca Tushnet, and Kirsten Weld, cross the disciplinary boundaries of First Amendment law, internet law, media policy, journalism, legal history, and legal theory, offering fresh perspectives on fortifying the speech system and reinvigorating the public square.
The Perilous Trade: Book Publishing in Canada, 1946-2006
by Roy MacskimmingA book that will fascinate and inform readers who love Canadian writing. Publishing Canadian books has always been an experiment. Like the great experiments of building a transcontinental railway and a national broadcasting system, it constitutes one of the nation's defining acts. Publishing, after all, is a people's way of telling its story to itself."-from the Introduction. Part cultural history, part personal memoir, this accomplished, sweeping, yet intimate book demonstrates that the story of Canadian publishing is one of the cornerstones of our literary history. In The Perilous Trade, former publisher, literary journalist, and industry insider Roy MacSkimming chronicles the extraordinary journey of English-language publishing from the Second World War to the present. During a period of unparalleled transformation, Canada grew from a cultural colony fed on the literary offerings of London and New York to a mature nation whose writers are celebrated around the world. Crucial to that evolution were three generations of book publishers - mavericks, gamblers, entrepreneurs, political activists, and true believers - sharing a conviction that Canadians need books of their own. Canadian publishing has long made headlines -be it Jack McClelland's outrageous publicity stunts, American takeovers, the collapse of venerable imprints, or bold political moves to ensure the industry's survival. Roy MacSkimming takes us behind the headlines to draw memorable portraits of the men and women who built Canada's literary renaissance. With a novelist's eye for character and incident, he weaves their tangled relationships with authors, agents, booksellers and each other into a lively narrative rich in anecdote and revealing personal recollection. Canadian publishers large and small have nurtured a literature of extraordinary diversity and breadth, MacSkimming argues, giving us English Canada's greatest cultural achievement.
The Perils of Extremism: How I Left the Oath Keepers and Why We Should be Concerned about a Future Civil War
by Jason Van TatenhoveAn explosive behind the scenes look at the Oath Keepers: what makes them tick, who they are, and what they REALLY stand for. The Oath Keepers first made a name for themselves with the infamous Bundy Ranch standoff in 2014. They have continued through to the US Capitol insurrection in early 2021. The Oath Keepers—including many former military members—have become one of the largest anti-government extremist groups in the United States, labeled one of the most dangerous domestic terror threats by the FBI. There have been countless articles and a few books written about the group, but nothing like this. Author Jason Van Tatenhove knows them from the inside. The Perils of Extremism is a first-hand account of the aging punk-rock journalist from Colorado as he was embedded with Stewart Rhodes and that most infamous militia, the Oath Keepers, as well as details from his time testifying to the United States House Select Committee on the January 6 Attack both in person live on TV on July 12, 2022 and during three and a half hours of taped deposition in March 2022. Jason takes the readers along on a journey that started with the Bundy Ranch Stand-off and continued with two more armed standoffs in Oregon and Montana. Jason was then offered a job as the national media director and associate editor for the Oath Keepers. He moved his family up to the Eureka, Montana area to start his job, where he found himself in a "who&’s who" of right-wing extremism. Jason even struck up a friendship with Stewart Rhodes when Stewart lived in Jason&’s basement for several months. Stewart confided in him about his actual beliefs and about how much of what he says publicly is to sell more memberships. Jason ultimately broke ties with the ever-radicalizing anti-government militia group when they begin to embrace the ideology of American Nazis and began associating with the spokesperson for the Alt-Right, Richard Spencer. From there, Jason began speaking out against the dangers of the extremist militia and tried to make amends in his life for being a part of something that led in part to the January 6 insurrection. Readers will also journey with Jason as he begins to be featured in documentaries, feature articles, and national news coverage as he speaks out against violent extremism. As mentioned, this book will also include his experiences testifying to congressional investigators.
The Perils of Print Culture
by Jason Mcelligott Eve PattenThis collection of essays illustrates various pressures and concerns--both practical and theoretical--related to the study of print culture. Procedural difficulties range from doubts about the reliability of digitized resources to concerns with the limiting parameters of 'national' book history.
Periodical Famines: Irish Memories in Transatlantic News Media, 1845–1919 (Irish Culture, Memory, Place)
by Lindsay JanssenLong recognized as Ireland's greatest demographic disaster in recent history, the Great Famine of 1845–1851 has shaped Irish identities around the world. From the monuments erected to commemorate its victims to the political rhetoric involving it to the novels, poems, songs, and films that it continues to inspire, the Famine remains a crucial part of Irish memory. Famine memories have also reached across history and national borders to establish links with cultural groups who were not directly connected to the Irish diaspora.Periodical Famines reveals how, within the transatlantic Irish periodical market between 1845 and 1910, Irish, Irish American, and Irish Canadian newspapers and magazines acted as carriers and shapers of cultural identities. Lindsay Janssen argues that famine memory was deployed transhistorically to help represent other crucial events in the Irish past, and periodicals used Famine recollections transnationally to give new meaning to events outside of Ireland, such as labor issues in the United States and the Second Boer War. Moving beyond individual writings to interrogate how different texts printed within a periodical issue influenced each other and affected audiences' attitudes to Irish hunger and distress, Janssen's cotextual approach reveals the intricate and sometimes divergent paths that Famine memory traveled through in the decades during and after its onset.Drawing upon a substantial corpus of creative and nonfiction periodical publications (including nearly 600 works of poetry and prose fiction), Periodical Famines is a thorough analysis of transatlantic Irish periodical culture during and after the Great Famine, demonstrating how periodicals' transmission of famine memories shaped global cultures.
The Periodical Press Revolution: E. S. Dallas and the Nineteenth-Century British Media System (Routledge Research in Journalism)
by Graham LawThis book explores a key aspect of journalism history from a sociological perspective: the rise of the periodical press. With a focus not on the economic and technological causes of this revolution but on the social and political consequences, the book takes a global look at this key development in the British press.Taking as a point of departure the theory of E.S. Dallas, who defined the periodical as 'the great event in modern history', the book explores these premises and conclusions regarding authorship, publishing, and readership, considering the nineteenth century as a whole. After an introductory section discussing questions of theory and method, the analysis first offers an overview of the quantitative growth of the periodical market, whether measured in terms of publications, readership, or authorship, before turning to a more detailed consideration of its qualitative determinants and effects, again distinguishing the same three aspects.Offering new insight into this key turning point in journalism history, this book will be of interest to all students and scholars of journalism and journalism history, media history, media and communication studies, British history, and modern history.
