On Being Certain: Believing You Are Right Even When You're Not - PDF
نویسندگان: خلاصه: You recognize when you know something for certain, right? You "know" the sky is blue, or that the traffic light had turned green, or where you were on the morning of September 11, 2001--you know these things, well, because you just do.In On Being Certain, neurologist Robert Burton challenges the notions of how we think about what we know. He shows that the feeling of certainty we have when we "know" something comes from sources beyond our control and knowledge. In fact, certainty is a mental sensation, rather than evidence of fact. Because this "feeling of knowing" seems like confirmation of knowledge, we tend to think of it as a product of reason. But an increasing body of evidence suggests that feelings such as certainty stem from primitive areas of the brain, and are independent of active, conscious reflection and reasoning. The feeling of knowing happens to us; we cannot make it happen.Bringing together cutting edge neuroscience, experimental data, and fascinating anecdotes, Robert Burton explores the inconsistent and sometimes paradoxical relationship between our thoughts and what we actually know. Provocative and groundbreaking, On Being Certain, will challenge what you know (or think you know) about the mind, knowledge, and reason.
Futurecast: How Superpowers, Populations, and Globalization Will Change the Way You Live and Work - PDF
نویسندگان: خلاصه: What will life be like in America, Europe, Japan or China in the year 2020?В As everyone’s lives across the world are become increasingly interconnected by globalization and new technologies quicken the pace of everything, the answer to that question depends on the fate and paths of the world’s major nations. В In Futurecast, Robert Shapiro, former U.S. Under Secretary of Commerce and Chairman/Co-founder of Sonecon, looks into the future to tell us what our world will over the next dozen years.В Though that time span seems brief, Shapiro foresees monumental changes caused by three historic new forces—globalization, the aging of societies, and the rise of America as a sole superpower with no near peer— will determine the paths of nations and the lives of countless millions. What jobs will there be for you and your children?В What will happen to your health care? How safe will you be at home or abroad?В Answers to these questions will depend, even more than today, on where you live in the world: • Even as China expands its military and its economy, America will be the world’s sole superpower for at least the next generation, and continue to lead efforts to preserve global security and stability. • The U.S. and China will be the world’s two indispensable economies, dominating the course of globalization. • Globalization will continue to shift most heavy manufacturing and millions of high-end service jobs from advanced countries like the US, to China, India, Indonesia, Mexico, Romania, Turkey and other developing nations. • Europe’s major nations and Japan will face the prospect of genuine economic decline and critical problems in their retirement pension systems, moving further towards the periphery of global economic and geopolitical power. • Every major country—the U.S., Europe, Japan, China—will face critical problems with their health care systems, and the entire world will face a crisis over energy and climate change.В В If one adds the wildcard of possible, catastrophic terrorist attacks to this mix, the period between now and 2020 will be as challenging as any in modern times. Taking these deep global developments into account when planning for the future isa necessity.В Robert Shapiro’s clear-eyed Futurecast is the knowledge portfolio you need to prepare for the years to come.
HCI International 2022 – Late Breaking Posters - Original PDF
نویسندگان: خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications
The History of Chile - Original PDF
نویسندگان: خلاصه: Within Chile is the driest desert in the world, the highest mountain range in the hemisphere, temperate rainforests, and a piece of Antarctica. In all these areas Chileans have created unique communities and, together, a vibrant nation. Chile's history mirrors its geographic variety. From its pre-colonial period, to its days as a Spanish colony, through its many independent governments, Chile has long been a land of crises and controversy. Beginning with a survey of the land, people, and current government of Chile, the book traces the chronological story of the country. Ten chapters follow the details of Chilean history from the indigenous peoples to the democratic transition after the Pinochet dictatorship. This is the perfect starting point for students and travelers interested in the history and people of Chile.
