Download or read book Diffracting Digital Images written by Ian Dawson and published by Routledge. This book was released on 2021-12-27 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital imaging techniques have been rapidly adopted within archaeology and cultural heritage practice for the accurate documentation of cultural artefacts. But what is a digital image, and how does it relate to digital photography? The authors of this book take a critical look at the practice and techniques of digital imaging from the stance of digital archaeologists, cultural heritage practitioners and digital artists. Borrowing from the feminist scholar Karen Barad, the authors ask what happens when we diffract the formal techniques of archaeological digital imaging through a different set of disciplinary concerns and practices. Diffracting exposes the differences between archaeologists, heritage practitioners and artists, and foregrounds how their differing practices and approaches enrich and inform each other. How might the digital imaging techniques used by archaeologists be adopted by digital artists, and what are the potentials associated with this adoption? Under the gaze of fine artists, what happens to the fidelity of the digital images made by archaeologists, and what new questions do we ask of the digital image? How can the critical approaches and practices of fine artists inform the future practice of digital imaging in archaeology and cultural heritage? Diffracting Digital Images will be of interest to students and scholars in archaeology, cultural heritage studies, anthropology, fine art, digital humanities, and media theory.

Download or read book Border Ecology written by Ila Nicole Sheren and published by Springer Nature. This book was released on 2023-03-10 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes how contemporary visual art can visualize environmental crisis. It draws on Karen Barad’s method of “agential realism,” which understands disparate factors as working together and “entangled.” Through an analysis of digital eco art, the book shows how the entwining of new materialist and decolonized approaches accounts for the nonhuman factors shaping ecological crises while understanding that a purely object-driven approach misses the histories of human inequality and subjugation encoded in the environment. The resulting synthesis is what the author terms a border ecology, an approach to eco art from its margins, gaps, and liminal zones, deliberately evoking the idea of an ecotone. This book is suitable for scholarly audiences within art history, criticism and practice, but also across disciplines such as the environmental humanities, media studies, border studies and literary eco-criticism.

Download or read book Aesthetics Digital Studies and Bernard Stiegler written by Noel Fitzpatrick and published by Bloomsbury Publishing USA. This book was released on 2021-07-29 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aesthetics, Digital Studies and Bernard Stiegler frames the intertwined relationship between artistic endeavours and scientific fields and their sociopolitical implications. Each chapter is either an explication of, or a critique of, some aspect of Bernard Stiegler's technological philosophy; as it is his technological-political-aesthetical-ethical theorisations which form the philosophical foundation of the volume. Emerging scholars bring critical new reflections to the subject area, while more established academics, researchers and practitioners outline the mutating nature of aesthetics within historical and theoretical frameworks. Not only is interdisciplinarity a prevailing topic at work within this collection, but so too is there a delineation of the mutating, hybrid role inhabited by the arts practitioner – at once engineer, scientist and artist – in the changing landscape of digital cultural production.

Download or read book Dismantling Cultural Borders Through Social Media and Digital Communications written by Emmanuel K. Ngwainmbi and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This beautifully curated volume dismantles cultural barriers in its exploration of Southern perspectives on digital communities, by drawing on Southern voices - either directly (Afghanistan, Brazil, Chile, China, Nigeria, South Africa, Vietnam) or through émigrés in the Global North (UK and US) - in equal measure. Discussion of identity negotiation, in contemporary international network society, offers an ideational feast for professionals and researchers in multiple fields with an interest in social media and identity, ethnicity, diversity." -Professor Naren Chitty A.M., Foundation Chair, International Communication & Editor-in-Chief, Journal of International Communication "...a compelling text that challenges us to interrogate the unique juxtaposition between networked communities and compromised identities. Nowhere else have I seen such an impressive and imaginative commentary on how social media may be devastatingly harmful to our collective sense of self." -Ronald L. Jackson II, Author of Encyclopedia of Identity and past President of the National Communication Association This book explores how social media and its networked communities dismantles, builds, and shapes identity. Social media has been instrumental, sometimes dangerously so, in binding together different communities; with thirteen original chapters by leading academics in the field, the volume investigates how belonging, togetherness, and loyalty is created in the digital sphere, in a way that transcends, and even dismantles, ethnic and national borders around the world. In tandem, the volume analyses the further threats to identity presented by the ease with which fabricated news and information spreads on social media, resulting in many users becoming unable to distinguish credible data from junk data. Social media is both creative and destructive in its influence on identity, and therefore the growing fake news crisis threatens the very stability of the world's communities. This book provides relevant theoretical frameworks and the latest empirical research findings in the area, including diverse case studies and analyses of social media experiences in indigenous and urban communities around the world, including China, Africa, and Central and South America. Emmanuel K. Ngwainmbi is a Professor in the Department of Communication Studies, University of North Carolina at Charlotte, USA.

Download or read book The Digital Coloniality of Power written by Alexander I. Stingl and published by Lexington Books. This book was released on 2015-12-16 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trouble is afoot in Digital Culture and Nerdland. These are, Alexander I. Stingl claims, not the engine of freedom and democracy that they once were hailed to be – this much is already clear in the wake of the snooping and surveillance crises that broke in recent years. Digitalization is but another version of the coloniality of power and being that has been at work for decades and centuries. He poses the question, whether Digital Age possess the legitimacy that ‘digitalization’ has claimed. His response is critically realistic, but he doesn’t stop at a critique for criticism’s sake. Inspired by the ideas of decolonial scholars, feminist science studies, current biological and neuro-cognitive research, and sociologists capable of reflection and self-criticism, Stingl attempts to ‘break’ the canvas of sociology and show that adding a third and decolonial dimension to the two-dimensional sociological imagination is indeed possible. He illustrates that it is possible that class-rooms, free speech on internet, and the inequalities in the production and distribution of a new form of social capital – digital cultural health care capital – can be subjected to a decolonial perspective along a sociological line of inquiry, if sociologists allow for relations with other disciplines and scholarship to be integrative conversations. The goal of this book is not to offer results or closed arguments but to create, instead, platforms for thinking further, opening new lines of inquiry, and to argue that it is not enough to identify problems or to attempt solve the problems with politics or best practice solutions. Instead, he proposes, we must learn to identify and make use of the opportunities that are produced by any problem. Stingl’s conclusion is, in short, that a sociology that takes the decolonial challenge and critique seriously, can not be a sociological (sub)discipline or a sociology of (a) problem, but it must be a sociology of opportunities.

Download or read book Digital Transmission written by Dayan Adionel Guimaraes and published by Springer Science & Business Media. This book was released on 2010-01-18 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital Transmission – A Simulation-Aided Introduction with VisSim/Comm is a book in which basic principles of digital communication, mainly pertaining to the physical layer, are emphasized. Nevertheless, these principles can serve as the fundamentals that will help the reader to understand more advanced topics and the associated technology. In this book, each topic is addressed in two different and complementary ways: theoretically and by simulation. The theoretical approach encompasses common subjects covering principles of digital transmission, like notions of probability and stochastic processes, signals and systems, baseband and passband signaling, signal-space representation, spread spectrum, multi-carrier and ultra wideband transmission, carrier and symbol-timing recovery, information theory and error-correcting codes. The simulation approach revisits the same subjects, focusing on the capabilities of the communication system simulation software VisSim/Comm on helping the reader to fulfill the gap between the theory and its practical meaning. The presentation of the theory is made easier with the help of 357 illustrations. A total of 101 simulation files supplied in the accompanying CD support the simulation-oriented approach. A full evaluation version and a viewer-only version of VisSim/Comm are also supplied in the CD.
