Posthuman Gaming: Avatars, Gamers, and Entangled Subjectivities (Routledge Advances in Game Studies)
by Poppy WildePosthuman Gaming: Avatars, Gamers, and Entangled Subjectivities explores the relationship between avatar and gamer in the massively multiplayer online roleplaying game World of Warcraft, to examine notions of entangled subjectivity, affects and embodiments – what it means and how it feels to be posthuman. With a focus on posthuman subjectivity, Wilde considers how we can begin to articulate ourselves when the boundary between self and other is unclear. Drawing on fieldnotes of her own gameplay experiences, the author analyses how subjectivity is formed in ways that defy a single individual notion of "self", and explores how different practices, feelings, and societal understandings can disrupt strict binaries and emphasise our posthumanism. She interrogates if one can speak of an "I" in the face of posthuman multiplicity, before exploring different analytical themes, beginning with how acting theories might be posthumanised and articulate the relationship between avatar and gamer. She then defines posthuman empathy and explains how this is experienced in gaming, before addressing the need to account for boredom, the complexity of nostalgia, and ways death and loss are experienced through gaming. This volume will appeal to a broad audience and is particularly relevant to scholars and students of cultural studies, media studies, humanities, and game studies.

Posthuman Property and Law: Commodification and Control through Information, Smart Spaces and Artificial Intelligence
by Jannice KällThis book analyses the phenomenon of digitally mediated property and considers how it problematises the boundary between human and nonhuman actors. The book addresses the increasingly porous border between personhood and property in digitized settings and considers how the increased commodification of knowledge makes visible a rupture in the liberal concept of the property owning, free, person. Engaging with the latest work in posthumanist and new materialist theory, it shows, how property as a concept as well as a means for control, changes fundamentally under advanced capitalism. Such change is exemplified by the way in which data, as an object of commodification, is extracted from human activities yet is also directly used to affectively control – or nudge – humans. Taking up a range of human engagements with digital platforms and coded architectures, as well as the circulation of affects through practices of artificial intelligence that are employed to shape behaviour, the book argues that property now needs to be understood according to an ecology of human as well as nonhuman actors. The idea of posthuman property, then, offers both a means to critique property control through digital technologies, as well as to move beyond the notion of the self-owning, object-owning, human. Engaging the most challenging contemporary technological developments, this book will appeal to researchers in the areas of Law and Technology, Legal Theory, Intellectual Property Law, Legal Philosophy, Sociology of Law, Sociology, and Media Studies.
Posthuman Research Practices in Education
by Carol A. Taylor Christina HughesHow do we include and develop understandings of those beyond-the-human aspects of the world in social research? Through fifteen contributions from leading international thinkers, this book provides original approaches to posthumanist research practices in education. It responds to questions which consider the effect and reach of posthuman research.
Posthumanism Meets Surveillance Capitalism: How to Delete the Manifest Image (Palgrave Studies in the Future of Humanity and its Successors)
by Patrick GamezThe core contention of this book is that, when viewed through the lens of contemporary posthuman theory, contemporary uses of AI under platform capitalism not only undermine our sense of the &“human&” but also our frameworks for conceptualizing ourselves as &“subjects&” or &“selves&” at all. This radical conclusion raises issues forces us to reckon with a new, disorienting horizon for critical thought at the intersection of technology and politics. This book demonstrates that two major streams of posthuman thought—namely, accelerationism and Prometheanism—can be interpreted as attempts to liberate our desires from our reason or our rationality from our all-too-human desire, each through the offloading of various tasks to emerging technologies. But, Patrick Gamez argues, the rise of opaque, unexplainable machine learning algorithms to predict and shape our behaviour undermines the common-sense models of mind through which we ultimately make sense of both the human and the posthuman.
Postinternet Art and Its Afterlives (Routledge Advances in Art and Visual Studies)
by Ian RothwellFocusing on the ‘postinternet’ art of the 2010s, this volume explores the widespread impact of recent internet culture on the formal and conceptual concerns of contemporary art. The ‘postinternet’ art movement is splintered and loosely defined, both in terms of its form and its politics, and has come under significant critique for this reason. This study will provide this definition, offering a much-needed critical context for this period of artistic activity that has had and is still having a major impact on contemporary culture. The book presents a picture of what the art and culture made within and against the constraints of the online experience look, sound, and feel like. It includes works by Petra Cortright, Jon Rafman, Jordan Wolfson, DIS, Amalia Ulman, and Thomas Ruff, and presents new analyses of case studies drawn from the online worlds of the 2010s, including vaporwave, anonymous image board culture, ‘irony bros’ and ‘edgelords’, viral extreme sports stunts, and GIFs. The book will be of interest to scholars working in art history, contemporary art, and digital culture.

Postprint: Books and Becoming Computational (The Wellek Library Lectures #109)
by N. Katherine HaylesSince Gutenberg’s time, every aspect of print has gradually changed. But the advent of computational media has exponentially increased the pace, transforming how books are composed, designed, edited, typeset, distributed, sold, and read. N. Katherine Hayles traces the emergence of what she identifies as the postprint condition, exploring how the interweaving of print and digital technologies has changed not only books but also language, authorship, and what it means to be human.Hayles considers the ways in which print has been enmeshed in literate societies and how these are changing as some of the cognitive tasks once performed exclusively by humans are now carried out by computational media. Interpretations and meaning-making practices circulate through transindividual collectivities created by interconnections between humans and computational media, which Hayles calls cognitive assemblages. Her theoretical framework conceptualizes innovations in print technology as redistributions of cognitive capabilities between humans and machines. Humanity is becoming computational, just as computational systems are edging toward processes once thought of as distinctively human. Books in all their diversity are also in the process of becoming computational, representing a crucial site of ongoing cognitive transformations.Hayles details the consequences for the humanities through interviews with scholars and university press professionals and considers the cultural implications in readings of two novels, The Silent History and The Word Exchange, that explore the postprint condition. Spanning fields including book studies, cultural theory, and media archeology, Postprint is a strikingly original consideration of the role of computational media in the ongoing evolution of humanity.
Postsecondary Play: The Role of Games and Social Media in Higher Education (Tech.edu: A Hopkins Series on Education and Technology)
by William G. Tierney, Zoë B. Corwin, Tracy Fullerton and Gisele RagusaGames and social media can improve college access, attract and support students, and boost rates of completion.The college application process—which entails multiple forms, essays, test scores, and deadlines—can be intimidating. For students without substantial school and family support, the complexity of this process can become a barrier to access. William G. Tierney, Tracy Fullerton, and their teams at the University of Southern California approach this challenge innovatively. Using the tools of online games and social media, they have developed ways to make applying for college much less intimidating.While the vast majority of college students use social media and gaming in their everyday lives, colleges and universities have been slow to recognize and harness the power of either. Postsecondary Play explores the significance of games and social media in higher education, and particularly how they can be used to attract, retain, educate, and socialize students.Tierney, a past president of the American Educational Research Association, has gathered some of the best research on the emerging role of games and social media in the classroom and how these tools can boost student confidence and increase college access. Scholars writing from a wide variety of disciplines—college access, social media, game studies, and learning sciences—provide concrete examples to illustrate the new and complex ways in which students learn in response to social media and games. Tierney and the contributors find that, although games can be powerful tools for encouraging underserved students, quality game design and mastering the concept of play—the ability to develop skills while engaging in the game—are essential in the effective use of serious games in teaching and learning.Summarizing a decade of research in game design and learning, Postsecondary Play will appeal to higher education scholars and students of learning, online gaming, education, and the media.

Power Composition for Photography
by Tom GallovichIn this book, Tom Gallovich shows readers how to use their camera's exposure controls (aperture, shutter speed, ISO) to establish the focal point of the image and create the overall mood of the shot and choose a particular lens or focal-length setting to massage the way elements in the original scene will appear within the frame. Next, he presents chapters on using shape, color, lines, and arrangement to strengthen the intended visual message. Readers will learn how to best place their primary subject (and in some cases secondary subject) for maximum impact and will discover artistic strategies that reinforce that decision through careful use of color, tone, highlight and shadow, leading lines, curved shapes, and relative size-qualities that will contribute to the overall mood in the image. Copious illustrations emphasize the impact that putting these concepts into play will have on your images-and these are often coupled with images that show how ineffective images are when those important compositional needs are not attended to.
