The Translation of Realia and Irrealia in Game Localization - Culture-Specificity between Realism and Fictionality (Hardcover):... The Translation of Realia and Irrealia in Game Localization - Culture-Specificity between Realism and Fictionality (Hardcover)
Silvia Pettini
R3,881 Discovery Miles 38 810 Ships in 12 - 17 working days

This book explores the impact of a video game's degree of realism or fictionality on its linguistic dimensions, investigating the challenges and strategies for translating realia and irrealia, the interface of the real world and the game world where culture-specificity manifests itself. The volume outlines the key elements in the translation of video games, such as textual non-linearity, multitextuality, and playability, and introduces the theoretical framework used to determine a game's respective degree of realism or fictionality. Pettini applies an interdisciplinary approach drawing on video game research and Descriptive Translation Studies to the linguistic and translational analysis of in-game dialogs in English-Italian and English-Spanish language pairs from a corpus of three war video games. This approach allows for an in-depth look at the localization challenges posed by the varying degree of realism and fictionality across video games and the different strategies translators employ in response to these challenges. A final chapter offers a comparative analysis of the three games and subsequently avenues for further research on the role of culture-specificity in game localization. This book is key reading for students and scholars interested in game localization, audiovisual translation studies, and video game research.

Immersion, Narrative, and Gender Crisis in Survival Horror Video Games (Hardcover): Andrei Nae Immersion, Narrative, and Gender Crisis in Survival Horror Video Games (Hardcover)
Andrei Nae
R3,877 Discovery Miles 38 770 Ships in 12 - 17 working days

This book investigates the narrativity of some of the most popular survival horror video games and the gender politics implicit in their storyworlds. In a thorough analysis of the genre that draws upon detailed comparisons with the mainstream action genre, Andrei Nae places his analysis firmly within a political and social context. In comparing survival horror games to the dominant game design norms of the action genre, the author differentiates between classical and postclassical survival horror games to show how the former reject the norms of the action genre and deliver a critique of the conservative gender politics of action games, while the latter are more heterogeneous in terms of their game design and, implicitly, gender politics. This book will appeal not only to scholars working in game studies, but also to scholars of horror, gender studies, popular culture, visual arts, genre studies and narratology.

Buckminster Fuller's World Game and Its Legacy (Hardcover): Timothy Stott Buckminster Fuller's World Game and Its Legacy (Hardcover)
Timothy Stott
R1,515 Discovery Miles 15 150 Ships in 12 - 17 working days

This book studies R. Buckminster Fuller's World Game and similar world games, past and present. Proposed by Fuller in 1964 and first played in colleges and universities across North America at a time of growing ecological crisis, the World Game attempted to turn data analysis, systems modelling, scenario building, computer technology, and information design to more egalitarian ends to meet human needs. It challenged players to redistribute finite planetary resources more equitably, to 'make the world work'. Criticised and lauded in equal measure, the World Game has evolved through several formats and continues today in correspondence with debates on planetary stewardship, gamification, data management, and the democratic deficit. This book looks again at how the World Game has been played, focusing on its architecture, design, and gameplay. With hindsight, the World Game might appear naive, utopian, or technocratic, but we share its problems, if not necessarily its solutions. Such a study will be of interest to scholars working in art history, design history, game studies, media studies, architecture, and the environmental humanities.

Steve Dixon
R1,190 Discovery Miles 11 900 Ships in 12 - 17 working days

Cybernetic-Existentialism: Freedom, Systems, and Being-for-Others in Contemporary Arts and Performance offers a unique discourse and an original aesthetic theory. It argues that fusing perspectives from the philosophy of Existentialism with insights from the 'universal science' of cybernetics provides a new analytical lens and deconstructive methodology to critique art. In this study, Steve Dixon examines how a range of artists' works reveal the ideas of Existentialist philosophers including Kierkegaard, Camus, de Beauvoir, and Sartre on freedom, being and nothingness, eternal recurrence, the absurd, and being-for-others. Simultaneously, these artworks are shown to engage in complex explorations of concepts proposed by cyberneticians including Wiener, Shannon, and Bateson on information theory and 'noise', feedback loops, circularity, adaptive ecosystems, autopoiesis, and emergence. Dixon's groundbreaking book demonstrates how fusing insights and knowledge from these two fields can throw new light on pressing issues within contemporary arts and culture, including authenticity, angst and alienation, homeostasis, radical politics, and the human as system.

R1,215 Discovery Miles 12 150 Ships in 12 - 17 working days

Computer Architectures is a collection of multidisciplinary historical works unearthing sites, concepts, and concerns that catalyzed the cross-contamination of computers and architecture in the mid-20th century. Weaving together intellectual, social, cultural, and material histories, this book paints the landscape that brought computing into the imagination, production, and management of the built environment, whilst foregrounding the impact of architecture in shaping technological development. The book is organized into sections corresponding to the classic von Neumann diagram for computer architecture: program (control unit), storage (memory), input/output and computation (arithmetic/logic unit), each acting as a quasi-material category for parsing debates among architects, engineers, mathematicians, and technologists. Collectively, authors bring forth the striking homologies between a computer program and an architectural program, a wall and an interface, computer memory and storage architectures, structures of mathematics and structures of things. The collection initiates new histories of knowledge and technology production that turn an eye toward disciplinary fusions and their institutional and intellectual drives. Constructing the common ground between design and computing, this collection addresses audiences working at the nexus of design, technology, and society, including historians and practitioners of design and architecture, science and technology scholars, and media studies scholars.

Andreas Suss
R1,386 Discovery Miles 13 860 Ships in 12 - 17 working days

This work is dedicated to CMOS based imaging with the emphasis on the noise modeling, characterization and optimization in order to contribute to the design of high performance imagers in general and range imagers in particular. CMOS is known to be superior to CCD due to its flexibility in terms of integration capabilities, but typically has to be enhanced to compete at parameters as for instance noise, dynamic range or spectral response. Temporal noise is an important topic, since it is one of the most crucial parameters that ultimately limits the performance and cannot be corrected. This work gathers the widespread theory on noise and extends the theory by a non-rigorous but potentially computing efficient algorithm to estimate noise in time sampled systems. This work contributed to two generations of LDPD based ToF range image sensors and proposed a new approach to implement the MSI PM ToF principle. This was verified to yield a significantly faster charge transfer, better linearity, dark current and matching performance. A non-linear and time-variant model is provided that takes into account undesired phenomena such as finite charge transfer speed and a parasitic sensitivity to light when the shutters should remain OFF, to allow for investigations of largesignal characteristics, sensitivity and precision. It was demonstrated that the model converges to a standard photodetector model and properly resembles the measurements. Finally the impact of these undesired phenomena on the range measurement performance is demonstrated.
