From herding cows in a rural village of Limpopo Province, to leading a revolution of workers marching to the Minister of Higher Education, Science and Technology of South Africa. In this sequel of Clearly Blurry: A story worth telling, the boy is now a man. The author takes you on a journey of self-discovery through the concrete jungle, characterized by personal and professional events that challenged him to discover his purpose in life. It is a brutal reality account that seeks to educate and inspire the reader to strive for more and think of the limitless possibilities one has by the discovery on your gifts. The reader will learn and be inspired to: -Take a gift or an idea and turn it into a way to make profit, - find ways to build your self-confidence in social and corporate spaces, - tips on how to identify a potential life partner and build a long-lasting relationship, - how you can deal with the loss of a parent or loved one, - and how a loss of income can become a wake up call to find ways of self-reliance and sustenance. This book is a well-balanced offering of word-art that will continue to inspire and entertain readers from all walks of life.

Examining established and emerging treatments for the correction of hyperopia and presbyopia, this reference offers guidance on technologies such as thermal or conductive keratoplasty, corneal implants, laser scleral relaxation, scleral expansion rings, intraocular lenses, and LASIK modifications.

A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science.

A ground-up Canadian text, Clear Thinking in a Blurry World offers a new way of examining the discipline of critical thinking. This text focuses on critical thinking as it applies to philosophy and cognition, rather than the typical 'formal logic lite' approach.Clear Thinking in a Blurry World includes many practical sections that are not commonly found in books in this market—material on numeracy and statistical analysis. Through this text, students will examine sources of information—from social exchanges, to science, to mainstream media—in detail, as well as the cognitive and social psychology of biases. This text aims directly at teaching, or beginning to teach, a broad set of knowledge, skills, and habits properly called critical reasoning faculties. Students using this text will enhance their ability to: -recognize and classify reliable and unreliable forms of reasoning -understand reasoning about evidence, including some central concepts of statistics and probability -anticipate the cognitive and social factors that make us susceptible to particular reasoning errors -critically examine science—and popular conceptions of science—in relation to the problem of how to believe reasonable things -examine the media and other main sources of information about the world to see how they might be unreliable, and under what circumstances

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.

Suggests techniques and therapeutic exercises for the eyes to keep them healthy.
