Vision Facts


Book Description

Vision Facts is a question and answer guide to the wonders of the human eye, its complex structures and the process of visual perception. It traces the journey of vision from a ray of light entering the eye to the processing done by the brain, to the development and aging of the human visual system and common disorders associated with both processes. Organized in an intuitive question-and-answer format and accompanied by clear diagrams, Vision Facts provides answers regarding your vision in a manner accessible to all who are interested. Each topic includes references to external resources such as lecture notes and research papers for those who wish to delve deeper. It is a perfect handbook for anyone who is interested in visual science, sensory processing, neuroscience, or physiology; and is an excellent reference for anyone considering a career in ophthalmology or optometry. Some examples of the questions include the following. What is the resolution of the eye? Why do astronomers often cover flashlights with a red filter while stargazing? What is color-blindness and how does it occur? What role does vision play in the circadian rhythm? What chemical signals cause the eye to develop into its mature form? How does alcohol during pregnancy affect eye development? How well can a newborn baby see? How does being born prematurely affect vision? What is 20/20 vision? How does aging affect vision? These are all questions that are addressed in Vision Facts, along with countless more.







Political Philosophy


Book Description

Political philosophy is not a well-defined field. It hovers between political theory and classical philosophy. Few early political thinkers could have anticipated the most pressing political issues of our time: the need to stop global warming; the reduction of nuclear armaments; the rise of inequality between individuals and nations; and the struggle against authoritarianism, particularly when it comes disguised as democracy or as socialism. Here, celebrated philosopher Mario Bunge masterfully integrates socio-political theory into a philosophical exploration of power and resource distribution in the world today. Bunge contends that even recent political thinkers have generally failed to address the political underpinnings of topical issues. Environmental degradation, gender and race discriminations, participative democracy, nationalism, imperialism, the North-South divide, resource wars, and the industrial-military complex have all largely been bypassed in political thinking. Even connections between poverty and environmental degradation, and between inequality and bad health, have escaped the attention of those who would call themselves political thinkers. Bunge believes that political philosophers should pay more attention to social indicators, such as the standard index of income inequality and the United Nations human development index. It is pointless to write about redistributive policies unless we have a shared understanding of current wealth distribution. This is, in short, a modern treatise on sociopolitical concerns.




A Conflict of Visions


Book Description

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.

The Vision


Book Description

Cassie Renfield finally has a handle on how the mark works. She knows she can intervene and attempt to change fate, but she also knows that saving one life could mean sacrificing another. The centuries old letter she found at the end of The Mark suggests she's a descendent of the Greek Fate, Lachesis, and that there are others out there with powers like hers. It's time to go find them. Now legally emancipated at 17, Cassie moves to Chicago to finish high school in a community where the Greek population is strong. She quickly discovers Demetria, a Greek girl who has visions of "the Angel of Death." But the Angel of Death is not Demetria, it's Zander-the cute Greek boy from school. His power allows him to help expedite a soul's journey from our world into the afterlife. He needs someone like Cassie-with the knowledge of a person's last day-in order to do his job successfully. But Cassie's not sure she's ready to willingly let marked people die....




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.




First Vision


Book Description

This is the biography of a contested memory, how it was born, grew, changed the world, and was changed by it. It's the story of the story of how the Church of Jesus Christ of Latter-day Saints began. Joseph Smith, the church's founder, remembered that his first audible prayer, uttered in spring of 1820 when he was about fourteen, was answered with a vision of heavenly beings. Appearing to the boy in the woods near his parents' home in western New York State, they told Smith that he was forgiven and warned him that Christianity had gone astray. Smith created a rich and controversial historical record by narrating and documenting this event repeatedly. In First Vision, Steven C. Harper shows how Latter-day Saints (beginning with Joseph Smith) and others have remembered this experience and rendered it meaningful. When and why and how did Joseph Smith's first vision, as saints know the event, become their seminal story? What challenges did it face along the way? What changes did it undergo as a result? Can it possibly hold its privileged position against the tides of doubt and disbelief, memory studies, and source criticism-all in the information age? Steven C. Harper tells the story of how Latter-day Saints forgot and then remembered accounts of Smith's experience and how Smith's 1838 account was redacted and canonized. He explores the dissonance many saints experienced after discovering multiple accounts of Smith's experience. He describes how, for many, the dissonance has been resolved by a reshaped collective memory.
