The Edge of Vision


Book Description

From the beginning, abstraction has been intrinsic to photography, and its persistent popularity reveals much about the medium. Now available in an affordable paperback edition, The Edge of Vision: The Rise of Abstraction in Photography is the first book in English to document this phenomenon and to put it into historical context, while also examining the diverse approaches thriving within contemporary photography. Author Lyle Rexer examines abstraction at pivotal moments, starting with the inception of photography, when many of the pioneers believed the camera might reveal other aspects of reality. The Edge of Vision traces subsequent explorations--from the Photo-Secessionists, who emphasized process and emotional expression over observed reality, to Modernist and Surrealist experiments. In the decades to follow, in particular from the 1950s through the 1980s, a multitude of photographers--Edward Weston, Aaron Siskind, Barbara Kasten, Ellen Carey and James Welling among them--took up abstraction from a variety of positions. Finally, Rexer explores the influence the history of abstraction exerts on contemporary thinking about the medium. Many contemporary artists--most prominently Penelope Umbrico, Michael Flomen, and Adam Broomberg and Oliver Chanarin--reject classic definitions of photography's documentary dimension in favor of other conceptually inflected possibilities, somewhere between painting and sculpture, that include the manipulation of process and printing. In addition to Rexer's engagingly written and richly illustrated history, this volume includes a selection of primary texts from and interviews with key practitioners and critics, such as Alvin Langdon Coburn, László Moholy-Nagy, Gottfried Jägger, Silvio Wolf and Walead Beshty.




At the Edges of Vision


Book Description

In At the Edges of Vision, Ren?van de Vall re-examines the aesthetics of spectatorship in terms of new-media art and visual culture. The aesthetic experience of visual art has traditionally been described in terms of the distanced contemplation and critical interpretation of the work's form and representational content. Recent developments in installation, video and computer art have foregrounded the bodily and affective engagement of the spectator and, in retrospect, throw into question the model of spectatorial distance for more traditional art forms as well. But what does this development entail for art's potential for reflective, imaginative and experiential depth? Is art still capable of providing a critical counterpoint to the ubiquitous presence of sensational, yet short-lived media imagery when it speaks to the senses rather than to the mind? In a thorough examination of examples from painting, film, installation art and interactive video, and computer art, Van de Vall argues for a tactile and affective conception of reflection, linking philosophy and art. Looking at a Rembrandt self-portrait and navigating through an internet art work have in common that both types of work rely on a playful, rhythmically structured, sensuous and embodied reflexivity for the articulation of meaning. This sensuous dimension of playful reflexivity is just as important in philosophical thought, however, as the transcendental condition for genuine, open-ended reflection. Drawing on the philosophy of Merleau-Ponty, Levinas, Lyotard and Deleuze on the one hand and on new-media theory on the other, Van de Vall develops a performative phenomenology of aesthetic reflection, visuality and visual art, in order to rethink art's ethical and political relevance in present-day digital-media culture.

Oxford Textbook of Vertigo and Imbalance


Book Description

Vertigo, dizziness, and imbalance rank amongst the most common presenting symptoms in neurology, ENT, geriatric medicine, and general practice. These symptoms can originate from many different organs and systems, such as the inner ear, general medical conditions, neurological and psychological disorders. The Oxford Textbook of Vertigo and Imbalance provides an up-to-date summary of the scientific basis, clinical diagnosis, and management of disorders leading to dizziness and poor balance. This textbook is conceptually divided into three sections, detailing the scientific basis, general clinical issues, and specific diseases diagnosed in clinical practice that are responsible for complaints of dizziness and imbalance. Individual chapters address benign paroxysmal positional vertigo, vestibular migraine, vestibular neuritis, stroke, and Ménière's disease. Additional chapters follow a syndrome-based approach and cover multiple conditions, including cerebellar disorders, bilateral vestibular failure and gait, and psychological disorders. The print edition is complemented by an online version, which allows access to the full content of the textbook, contains links from the references to primary research journal articles, allows full text searches, and provides access to figures and tables that can be downloaded to PowerPoint. It serves a useful clinical reference for neurologists, otorhinolaryngologists, audio-vestibular physicians, and senior trainees in those specialties.




Making Eye Health a Population Health Imperative


Book Description

The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.




Visual Impairments


Book Description

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.




Introduction to Psychology


Book Description

This book is designed to help students organize their thinking about psychology at a conceptual level. The focus on behaviour and empiricism has produced a text that is better organized, has fewer chapters, and is somewhat shorter than many of the leading books. The beginning of each section includes learning objectives; throughout the body of each section are key terms in bold followed by their definitions in italics; key takeaways, and exercises and critical thinking activities end each section.

Designing with the Mind in Mind


Book Description

In this completely updated and revised edition of Designing with the Mind in Mind, Jeff Johnson provides you with just enough background in perceptual and cognitive psychology that user interface (UI) design guidelines make intuitive sense rather than being just a list or rules to follow. Early UI practitioners were trained in cognitive psychology, and developed UI design rules based on it. But as the field has evolved since the first edition of this book, designers enter the field from many disciplines. Practitioners today have enough experience in UI design that they have been exposed to design rules, but it is essential that they understand the psychology behind the rules in order to effectively apply them. In this new edition, you'll find new chapters on human choice and decision making, hand-eye coordination and attention, as well as new examples, figures, and explanations throughout. Provides an essential source for user interface design rules and how, when, and why to apply them Arms designers with the science behind each design rule, allowing them to make informed decisions in projects, and to explain those decisions to others Equips readers with the knowledge to make educated tradeoffs between competing rules, project deadlines, and budget pressures Completely updated and revised, including additional coverage on human choice and decision making, hand-eye coordination and attention, and new mobile and touch-screen examples throughout
