Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Purkinje s Vision written by Nicholas J. Wade and published by Psychology Press. This book was released on 2001-04-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life of Jan Evangelista Purkinje (1787-1869) has fascinated students from many disciplines. Histologists marvel at his early descriptions of cells; physiologists admire his attempts to relate structure to function; pharmacologists view in awe his heroic experiments on self-administered drugs; forensic scientists acknowledge his role in the use of fingerprints for identification; and Czech patriots salute his awakening of pride in their nation. Yet all these achievements followed his initial enquiries into vision. It is this psychological dimension that fostered this collaboration. As the title suggests, the present volume is bifocal. In the narrow sense it refers to Purkinje's studies of vision, but in its broader view it concerns Purkinje's anticipation of neuroscience. Purkinje provided evidence to support both its cellular and its conceptual base. At the cellular level his acute vision is immortalized within our bodies. At the conceptual level, he sought to relate subjective phenomena to their objective underpinnings--to link psychology to physiology. Vision provides a bond that unites psychology and physiology, and it is this bond that was strengthened by Purkinje's enquiries. The authors have tried to provide a context in which Purkinje's descriptions of visual phenomena can be placed. In some cases this exposes clear precursors of research for which Purkinje has been credited. In others, there was nothing to suggest the phenomena that he exposed. The book translates Purkinje's initial masterpiece on subjective vision and places it in the context of emerging views of neuroscience.

Download or read book Faint Objects and How to Observe Them written by Brian Cudnik and published by Springer Science & Business Media. This book was released on 2012-09-18 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faint Objects and How to Observe Them is for visual observers who are equipped with a 10-inch or larger astronomical telescope and who want to "go deep" with their observing. It provides a guide to some of the most distant, dim, and rarely observed objects in the sky, supported by background information on surveys and objects lists - some familiar, such as Caldwell, and some not so familiar. This book not only provides a wealth of experience compiled from several sources, but it also gives an historical background to surveys whose names may or may not be familiar to most amateur astronomers. Finally, it includes a listing of the many galaxy clusters out there, from "nearby" ones such as Stefan's Quintet to some of the most distant groups observable through the largest telescopes.

Download or read book Observing Comets Asteroids Meteors and the Zodiacal Light written by Stephen J. Edberg and published by Cambridge University Press. This book was released on 1994-10-06 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: When can you see fireballs and who should you contact if you spot one? When is it best to hunt for comets and meteors and whereabouts? How do you gauge the size of the coma in the head of a comet and estimate its degree of condensation? Clear and easy to use, this guide shows you how to make successful and valuable observations and records of comets, asteroids, meteors and the zodiacal light. For each topic the historical background and current scientific understanding support a wealth of observational techniques. Comet observers are shown techniques for search and discovery. They can learn how to make visual estimates of brightness and size, and how to make photographic studies of cometary heads and tails. Asteroid hunters will find a 'life list' of quarry and guidelines on how to search for these objects and then how to photograph or electronically image them. Fruitful photographic and electronic methods for studying meteors and meteor showers are provided. Visual and photographic techniques show you how to examine the often elusive zodiacal light. The more adventurous are provided with advanced techniques on how to make successful astrometric, spectroscopic and electronic observations. This is rounded off with an invaluable list of centres world-wide to contact with your details of unusual sightings.
