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.

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.
Performing Artists and Precarity: Work in the Contemporary Entertainment Industries
by Melissa Tyler Philip HancockThis 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.

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 Linda L. Putnam Gail T. FairhurstPerforming 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 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.
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.
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.
Periodismo escrito con sangre
by Javier Valdez CárdenasPeriodismo escrito con sangre es un homenaje al periodista ejecutado por decir la verdad, por dar voz a los desposeídos, a quienes tienen en el rostro la herida viva, ardiente, ocasionada por el crimen organizado y la indiferencia o complicidad de las autoridades. Selección, prólogo y notas: César Ramos. El 15 de mayo de 2017 fue asesinado en Culiacán el periodista Javier Valdez Cárdenas, autor de una serie de libros excepcionales para entender el fenómeno del narco y el voraz crecimiento de la delincuencia organizada en México. Periodista valiente y puntual, crítico hasta el extremo con la realidad de nuestro país, su trabajo logró reconocimiento internacional y, sobre todo, por una pluma vibrante, conmovedora, profundamente humana. Se recogen en este libro trabajos de sus libros Miss Narco, Los morros del narco, Levantones, Con una granada enla boca, Huérfanos del narco y Narcoperiodismo. Hay un denominador común en las crónicas, investigaciones y reportajes de Valdez Cárdenas: su acercamiento intenso al ser humano, a las madres muertas en vida por no saber de sus hijos; al adicto que mira derrumbarse toda ilusión en un escenario de violencia impasible; a la víctima del levantón, del ejercicio terrible del sicario; al policía baleado; al niño despojado de toda esperanza en una casa donde se come desgracia; a las jóvenes que cambiaron la ilusión por el infierno del narco, el glamour por la ejecución feroz en un baldío. Queda claro que Javier Valdez Cárdenas vive ahora en sus escritos y justo, imprescindible, es leer su trabajo periodístico porque esa voz no será apagada jamás por ningún balazo.
Peripheral Actors in Journalism: Deviating from the Norm? (Routledge Focus on Journalism Studies)
by Aljosha Karim SchapalsThis book addresses the transformative role that so-called peripheral actors in journalism – emerging outlets diverging from the norms fiercely held by mainstream media outlets – play in today’s news ecosystem. The author charts the rise to prominence of these actors, outlining how they have successfully managed to challenge the authority held by mainstream, legacy outlets, whose claims to be the “storytellers of our time” no longer exclusively pertain to them. Beginning by identifying these peripheral actors specifically, the book then considers whether what they do is “journalism” as traditionally conceived, what their motivations are, and why their role is important in light of journalism’s democratic function in holding power to account. Ultimately, it is argued that, despite the perceived role of peripheral actors as “deviant”, they still demonstrate a surprising degree of ideological continuity in the face of industrial disruption. Drawing on research from Australia, Germany, and the United Kingdom, Peripheral Actors in Journalism is an insightful resource for journalism and media scholars with an interest in alternative media sources.
