The relationship between language and other aspects of conceptual development is one of the central issues in child language acquisition. One view holds that language is a special capacity, separate from other areas of cognition and learning.
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.
Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.
Thomas Sowell’s “extraordinary” explication of the competing visions of human nature lie at the heart of our political conflicts (New York Times) Controversies in politics arise from many sources, but the conflicts that endure for generations or centuries show a remarkably consistent pattern. In this classic work, Thomas Sowell analyzes this pattern. He describes the two competing visions that shape our debates about the nature of reason, justice, equality, and power: the "constrained" vision, which sees human nature as unchanging and selfish, and the "unconstrained" vision, in which human nature is malleable and perfectible. A Conflict of Visions offers a convincing case that ethical and policy disputes circle around the disparity between both outlooks.
Jonathan Crary's Techniques of the Observer provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. This analysis of the historical formation of the observer is a compelling account of the prehistory of the society of the spectacle. In Techniques of the Observer Jonathan Crary provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. Inverting conventional approaches, Crary considers the problem of visuality not through the study of art works and images, but by analyzing the historical construction of the observer. He insists that the problems of vision are inseparable from the operation of social power and examines how, beginning in the 1820s, the observer became the site of new discourses and practices that situated vision within the body as a physiological event. Alongside the sudden appearance of physiological optics, Crary points out, theories and models of "subjective vision" were developed that gave the observer a new autonomy and productivity while simultaneously allowing new forms of control and standardization of vision. Crary examines a range of diverse work in philosophy, in the empirical sciences, and in the elements of an emerging mass visual culture. He discusses at length the significance of optical apparatuses such as the stereoscope and of precinematic devices, detailing how they were the product of new physiological knowledge. He also shows how these forms of mass culture, usually labeled as "realist," were in fact based on abstract models of vision, and he suggests that mimetic or perspectival notions of vision and representation were initially abandoned in the first half of the nineteenth century within a variety of powerful institutions and discourses, well before the modernist painting of the 1870s and 1880s.
A Smithsonian Magazine Best History Book of 2018 The unknown history of two ideas crucial to the struggle over what America stands for In Behold, America, Sarah Churchwell offers a surprising account of twentieth-century Americans' fierce battle for the nation's soul. It follows the stories of two phrases -- the "American dream" and "America First" -- that once embodied opposing visions for America. Starting as a Republican motto before becoming a hugely influential isolationist slogan during World War I, America First was always closely linked with authoritarianism and white supremacy. The American dream, meanwhile, initially represented a broad vision of democratic and economic equality. Churchwell traces these notions through the 1920s boom, the Depression, and the rise of fascism at home and abroad, laying bare the persistent appeal of demagoguery in America and showing us how it was resisted. At a time when many ask what America's future holds, Behold, America is a revelatory, unvarnished portrait of where we have been.
The Byzantines used imagery to communicate a wide range of issues. In the context of Iconoclasm - the debate about the legitimacy of religious art conducted between c. AD 730 and 843 - Byzantine authors themselves claimed that visual images could express certain ideas better than words. Vision and Meaning in Ninth-Century Byzantium deals with how such visual communication worked and examines the types of messages that pictures could convey in the aftermath of Iconoclasm. Its focus is on a deluxe manuscript commissioned around 880, a copy of the fourth-century sermons of the Cappadocian church father Gregory of Nazianzus which presented to the Emperor Basil I, founder of the Macedonian dynasty, by one of the greatest scholars Byzantium ever produced, the patriarch Photios. The manuscript was lavishly decorated with gilded initials, elaborate headpieces and a full-page miniature before each of Gregory's sermons. Forty-six of these, including over 200 distinct scenes, survive. Fewer than half however were directly inspired by the homily that they accompany. Instead most function as commentaries on the ninth-century court and carefully deconstructed both provide us with information not available from preserved written sources and perhaps more important show us how visual images communicate differently from words.
Winner of the Gustave O. Arlt Award in the Humanities Three understandings of the nature of religion--religion as experience, symbolic meaning, and power--have dominated scholarly discussions, in succession, for the past hundred years. Proponents of each of these three approaches have tended to downplay, ignore, or actively criticize the others. But why should the three approaches be at odds? Religion as it is practiced involves experiences, meanings, and power, so students of religion should attend to all three. Furthermore, theorists of religion should have an account that carefully conceptualizes all three aspects, without regarding any of them as more basic than the others. Visions of Religion provides just such an account. Stephen S. Bush examines influential proponents of the three visions, arguing that each approach offers substantial and lasting contributions to the study of religion, although each requires revision. Bush rehabilitates the concepts of experience and meaning, two categories that are much maligned these days. In doing so, he shows the extent to which these categories are implicated in matters of social power. As for power, the book argues that the analysis of power requires attention to meaning and experience. Visions of Religion accomplishes all this by articulating a social practical theory of religion that can account for all three aspects, even as it incorporates them into a single theoretical framework.
