Book excerpt: In Portugal between 2005 and 2010, “modernization through technology” was the major political motto used to develop and improve the country’s peripheral and backward condition. This study reflects on one of the resulting, specific aspects of this trend—the implementation of public video surveillance. The in-depth ethnography provides evidence of how the political construction of security and surveillance as a strategic program actually conceals intricate institutional relationships between political decision-makers and common citizens. Essentially, the detailed account of the major actors, as well as their roles and motivations, serves to explain phenomena such as the confusion between objective data and subjective perceptions or the lack of communication between parties, which as this study argues, underlies the idiosyncrasies and fragilities of Portugal’s still relatively young democratic system.

This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Emergent Techniques for Assessment of Visual Performance written by National Research Council and published by National Academies Press. This book was released on 1985-01-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Visual Impairments written by National Research Council and published by National Academies Press. This book was released on 2002-08-17 with total page 369 pages. 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 Peripheral Visions written by Lisa Wedeen and published by University of Chicago Press. This book was released on 2009-08-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The government of Yemen, unified since 1990, remains largely incapable of controlling violence or providing goods and services to its population, but the regime continues to endure despite its fragility and peripheral location in the global political and economic order. Revealing what holds Yemen together in such tenuous circumstances, Peripheral Visions shows how citizens form national attachments even in the absence of strong state institutions. Lisa Wedeen, who spent a year and a half in Yemen observing and interviewing its residents, argues that national solidarity in such weak states tends to arise not from attachments to institutions but through both extraordinary events and the ordinary activities of everyday life. Yemenis, for example, regularly gather to chew qat, a leafy drug similar to caffeine, as they engage in wide-ranging and sometimes influential public discussions of even the most divisive political and social issues. These lively debates exemplify Wedeen’s contention that democratic, national, and pious solidarities work as ongoing, performative practices that enact and reproduce a citizenry’s shared points of reference. Ultimately, her skillful evocations of such practices shift attention away from a narrow focus on government institutions and electoral competition and toward the substantive experience of participatory politics.
