Transforming Global Information and Communication Markets
by Donald Abelson Jonathan D. Aronson Peter F. CowheyInnovation in information and communication technology (ICT) fuels the growth of the global economy. How ICT markets evolve depends on politics and policy, and since the 1950s periodic overhauls of ICT policy have transformed competition and innovation. For example, in the 1980s and the 1990s a revolution in communication policy (the introduction of sweeping competition) also transformed the information market. Today, the diffusion of Internet, wireless, and broadband technology, growing modularity in the design of technologies, distributed computing infrastructures, and rapidly changing business models signal another shift. This pathbreaking examination of ICT from a political economy perspective argues that continued rapid innovation and economic growth require new approaches in global governance that will reconcile diverse interests and enable competition to flourish. The authors (two of whom were architects of international ICT policy reforms in the 1990s) discuss this crucial turning point in both theoretical and practical terms.
Blown to Bits: Your Life, Liberty, and Happiness After the Digital Explosion
by Hal Abelson Ken Ledeen Harry Lewis"For thousands of years, people have been saying that the world is changing and will never again be the same. Yet the profound changes happening today are different, because they result from a specific technological development. It is now possible, in principle, to remember everything that anyone says, writes, sings, draws, or photographs. Everything. If digitized, the world has enough disks and memory chips to save it all, for as long as civilization can keep producing computers and disk drives. Global computer networks can make it available to everywhere in the world, almost instantly. And computers are powerful enough to extract meaning from all that information, to find patterns and make connections in the blink of an eye. <p><p>In centuries gone by, others may have dreamed these things could happen, in Utopian fantasies or in nightmares. But now they are happening. We are living in the middle of the changes, and we can see the changes happening. But we don't know how things will turn out. Right now, governments and the other institutions of human societies are deciding how to use the new possibilities. Each of us is participating as we make decisions for ourselves, for our families, and for people we work with. Everyone needs to know how their world and the world around them is changing as a result of this explosion of digital information. Everyone should know how the decisions will affect their lives, and the lives of their children and grandchildren and everyone who comes after. That is why we wrote this book." - By the Authors

Structure and Interpretation of Computer Programs: JavaScript Edition (MIT Electrical Engineering and Computer Science)
by Harold Abelson Gerald Jay SussmanA new version of the classic and widely used text adapted for the JavaScript programming language.Since the publication of its first edition in 1984 and its second edition in 1996, Structure and Interpretation of Computer Programs (SICP) has influenced computer science curricula around the world. Widely adopted as a textbook, the book has its origins in a popular entry-level computer science course taught by Harold Abelson and Gerald Jay Sussman at MIT. SICP introduces the reader to central ideas of computation by establishing a series of mental models for computation. Earlier editions used the programming language Scheme in their program examples. This new version of the second edition has been adapted for JavaScript. The first three chapters of SICP cover programming concepts that are common to all modern high-level programming languages. Chapters four and five, which used Scheme to formulate language processors for Scheme, required significant revision. Chapter four offers new material, in particular an introduction to the notion of program parsing. The evaluator and compiler in chapter five introduce a subtle stack discipline to support return statements (a prominent feature of statement-oriented languages) without sacrificing tail recursion. The JavaScript programs included in the book run in any implementation of the language that complies with the ECMAScript 2020 specification, using the JavaScript package sicp provided by the MIT Press website.

AI and Cognitive Modelling for Education
by Boris Aberšek Andrej Flogie Igor PesekThis book offers a groundbreaking approach to bridging the gap between various disciplines involved in cognitive modeling in education. By drawing on the fields of learning, neuro science, cognitive science, neurobiology, and computer science, it provides a new perspective on how we can integrate these disciplines with education to create more effective learning environments. The main objective of this book is to delve into the ethical, sociological, and technological questions surrounding the introduction of intelligent and smart learning environments in education. By analyzing these issues, this book aims to bridge the gap between the various disciplines involved in cognitive modeling and education, while highlighting the benefits and risks associated with these advancements. With the emergence of AI-based tutors, coaches, and learning environments, students now have access to a new type of self-learning and self-training that was previously unavailable. Distance learning has become increasingly popular in recent years, and the use of computer-assisted learning tools has revolutionized the way we think about education. The goal of education must be to instill in students a desire to learn for themselves, and this can only be achieved through active, self-directed, and reflective learning. With intelligent tutoring systems, students are empowered to take an active role in their own education, rather than simply being passive recipients of information. This book offers practical strategies for teachers to facilitate this transition, enabling them to act as facilitators and guides rather than one-way communicators. By embracing this new approach to education, we can help students become lifelong learners who are equipped with the skills they need to succeed in the 21st century. As we cannot predict the future with certainty, the true effects of education may only be revealed in the long run, making it critical to understand the potential consequences of introducing these new learning tools. By exploring these complex topics, this book offers valuable insights for educators, policymakers, and anyone interested in the future of education.
The Complete Idiot's Guide to Social Media Marketing, 2nd Edition
by Jennifer AbernethyThe Complete Idiot's Guide® to Social Media Marketing, Second Edition, covers cutting-edge techniques for small and large businesses alike. Ask the AuthorQ: How has social media marketing changed business and personal lives?A: The playing field has been leveled for business. No longer do you need a 6 or 7 figure budget to reach people around the country or globe for that matter. Personally, many lives have been affected. Many people more connected, businesses have grown because of the connections, TV and singing careers have been launched, money has been raised for charity, books have been marketed and purchased, and so on.Q: What has been the most challenging part of utilizing social media?A: I think the learning curve. With all of these sites . . . they come with no directions and no LIVE phone number.Q: What has worked the best and worst thus far?A: Facebook because of it&’s broad reach really has worked for me, but many would argue that YouTube works the best; particularly since it is the search engine of choice with the 11–34 age group.Q: How can a person searching for a job use social media marketing?A: So many ways. . . . They need to be on LinkedIn with a professional looking profile, photo, and contact information. They could also utilize video to begin sharing their expertise. Candidates need to stand out in a crowd of millions so if they say . . . sent in a video introducing themselves and a video follow up email . . . that would wow them!Q: What is the newest thing since Twitter?A: I believe companies and individuals are starting to utilize audio for creating their own iTunes channel, and also location-based social media like FourSquare. I personally, am not sold on location based services as of yet from a safety point of view, but for retailers it can be a good thing. I believe video is going to explode in popularity in 2011 for the 35+ market as well. They just need to get comfortable being on camera!

Optimization Techniques in Computer Vision
by Mongi A. Abidi Andrei V. Gribok Joonki PaikThis book presents practical optimization techniques used in image processing and computer vision problems. Ill-posed problems are introduced and used as examples to show how each type of problem is related to typical image processing and computer vision problems. Unconstrained optimization gives the best solution based on numerical minimization of a single, scalar-valued objective function or cost function. Unconstrained optimization problems have been intensively studied, and many algorithms and tools have been developed to solve them. Most practical optimization problems, however, arise with a set of constraints. Typical examples of constraints include: (i) pre-specified pixel intensity range, (ii) smoothness or correlation with neighboring information, (iii) existence on a certain contour of lines or curves, and (iv) given statistical or spectral characteristics of the solution. Regularized optimization is a special method used to solve a class of constrained optimization problems. The term regularization refers to the transformation of an objective function with constraints into a different objective function, automatically reflecting constraints in the unconstrained minimization process. Because of its simplicity and efficiency, regularized optimization has many application areas, such as image restoration, image reconstruction, optical flow estimation, etc. Optimization plays a major role in a wide variety of theories for image processing and computer vision. Various optimization techniques are used at different levels for these problems, and this volume summarizes and explains these techniques as applied to image processing and computer vision.
