Information Systems: A Manager’s Guide to Harnessing Technology
by John GallaugherThe text offers a proven approach that has garnered student praise, increased IS enrollment, and engaged students to think deeper and more practically about the space where business and technology meet. Every topic is related to specific business examples, so students gain an immediate appreciation of its importance. Rather than lead with technical topics, the book starts with strategic thinking, focusing on big-picture issues that have confounded experts but will engage students. And while chapters introduce concepts, cases on approachable, exciting firms across industries further challenge students to apply what they've learned, asking questions like: Why was NetFlix able to repel Blockbuster and WalMart? How did Harrah's Casino's become twice as profitable as comparably-sized Caesar's, enabling the former to acquire the latter? How does Spain's fashion giant Zara, a firm that shuns the sort of offshore manufacturing used by every other popular clothing chain, offer cheap fashions that fly off the shelves, all while achieving growth rates and profit margins that put Gap to shame? What's an IPO and can a technology alternative push out investment bankers and insiders to the benefit of entrepreneurs and small investors? Why is Google more profitable than Disney? Is Facebook really worth $15 billion?
Learning with Mobile and Handheld Technologies: Inside And Outside The Classroom
by John Galloway Merlin John Maureen McTaggartAs technology evolves we are ever more reliant on the use of handheld and mobile devices, yet what do we know about their impact on learning? While there is a lot of interest in mobile technology, many schools still aren’t sure how to best use it for learning and teaching. Learning with Handhelds and Mobiles explores this landscape and offers examples of how these technologies have been used for learning, how the problems that have arisen are being addressed, and offers ideas for the future. This invaluable book gives a voice to teachers and educators using mobiles and technology-enhanced learning in and out of schools, for regular school work and for innovative projects through exciting partnerships like Apps for Good. Learning with Handhelds and Mobiles shows the changes that are taking place within schools as a direct result of these emerging technologies, and contains case studies with accounts of best practice in a variety of settings including primary, secondary, and special schools, and learning beyond their boundaries. The book also explores themes of pedagogy, communication and affordances, collaborative learning, individual creativity and expression, self-directed and informal learning and outdoor education. The learning potential of handheld and mobile devices has excited teachers and educators, but until now there has been no structured, systematic overview available along with reflections on how this technology is changing educational practice. This book brings these together to provide a clearer picture of what is currently a fragmented area, and offers expert views of how we can understand these, and where it may take us next.
Sign of the Apocalypse: Ruminations and Wit from an American Roadside Prophet
by John GetchellFriends, neighbors, and passersby from all over the country can’t fail to miss “The Sign’s constantly changing humor and insight. On occasion, The Sign of the Apocalypse (SOTA) traffics in the earnest, but at its heart is rooted in a deep-seated desire to express the sarcastic and snort-worthy. This, and a love of haiku, pizza, Latin, double entendre, and the worst puns ever crafted. Two years in the making, the message on “The Sign” is changed on a daily basis, with the primary benefit of slowing passing traffic to a honking crawl. It was designed to convey pithy tidbits of thought and wordplay. In its conception, SOTA was perpetrated in spite of the objection of the author's girlfriend, and with hopes of creating controversy and dismay in the local community. The girlfriend packed up and left, and the community and town fathers were surprisingly gruntled by the proceedings. Punny and sarcastic signs include: • When attacked by a gang of clowns, go for the juggler • What if doing the hokey pokey really is what it’s all about? • Legalize marinara • A penny saved is ridiculous • Wendy, please take me back / I’m so miserable / it’s almost like / you’re still here

Excel© 2007 VBA Programmer's Reference
by John GreenThis book is aimed squarely at Excel users who want to harness the power of the VBA language in their Excel applications. At all times, the VBA language is presented in the context of Excel, not just as a general application programming language. The Primer has been written for those who are new to VBA programming and the Excel object model. It introduces the VBA language and the features of the language that are common to all VBA applications. It explains the relationship between collections, objects, properties, methods, and events and shows how to relate these concepts to Excel through its object model. It also shows how to use the Visual Basic Editor and its multitude of tools, including how to obtain help. The middle section of the book takes the key objects in Excel and shows, through many practical examples, how to go about working with those objects. The techniques presented have been developed through the exchange of ideas of many talented Excel VBA programmers over many years and show the best way to gain access to workbooks, worksheets, charts, ranges, and so on. The emphasis is on efficiency--that is, how to write code that is readable and easy to maintain and that runs at maximum speed. In addition, the chapters devoted to accessing external databases detail techniques for accessing data in a range of formats. The final four chapters of the book address the following advanced issues: linking Excel to the Internet, writing code for international compatibility, programming the Visual Basic Editor, and how to use the functions in the Win32 API (Windows 32-bit Application Programming Interface).
Computing with Quantum Cats
by John GribbinA mind-blowing glimpse into the near future, where quantum computing will have world-transforming effects.The quantum computer is no longer the stuff of science fiction. Pioneering physicists are on the brink of unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schrödinger's famous "dead and alive" cat, rely on entities like electrons, photons, or atoms existing in two states at the same time - is set to turn the computing world on its head.In his fascinating study of this cutting-edge technology, John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where "everything is real." Looking back to Alan Turing's work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through "intuition" and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to create a world where communication occurs faster than light and teleportation is possible.This is an exciting insider's look at the new frontier of computer science and its revolutionary implications.
Dynamic Models in Biology
by John Guckenheimer Stephen P. EllnerFrom controlling disease outbreaks to predicting heart attacks, dynamic models are increasingly crucial for understanding biological processes. Many universities are starting undergraduate programs in computational biology to introduce students to this rapidly growing field. In Dynamic Models in Biology, the first text on dynamic models specifically written for undergraduate students in the biological sciences, ecologist Stephen Ellner and mathematician John Guckenheimer teach students how to understand, build, and use dynamic models in biology. Developed from a course taught by Ellner and Guckenheimer at Cornell University, the book is organized around biological applications, with mathematics and computing developed through case studies at the molecular, cellular, and population levels. The authors cover both simple analytic models--the sort usually found in mathematical biology texts--and the complex computational models now used by both biologists and mathematicians. Linked to a Web site with computer-lab materials and exercises, Dynamic Models in Biology is a major new introduction to dynamic models for students in the biological sciences, mathematics, and engineering.

Signals and Boundaries: Building Blocks for Complex Adaptive Systems
by John H. HollandComplex adaptive systems (cas), including ecosystems, governments, biological cells, and markets, are characterized by intricate hierarchical arrangements of boundaries and signals. In ecosystems, for example, niches act as semi-permeable boundaries, and smells and visual patterns serve as signals; governments have departmental hierarchies with memoranda acting as signals; and so it is with other cas. Despite a wealth of data and descriptions concerning different cas, there remain many unanswered questions about "steering" these systems. In Signals and Boundaries, John Holland argues that understanding the origin of the intricate signal/border hierarchies of these systems is the key to answering such questions. He develops an overarching framework for comparing and steering cas through the mechanisms that generate their signal/boundary hierarchies. Holland lays out a path for developing the framework that emphasizes agents, niches, theory, and mathematical models. He discusses, among other topics, theory construction; signal-processing agents; networks as representations of signal/boundary interaction; adaptation; recombination and reproduction; the use of tagged urn models (adapted from elementary probability theory) to represent boundary hierarchies; finitely generated systems as a way to tie the models examined into a single framework; the framework itself, illustrated by a simple finitely generated version of the development of a multi-celled organism; and Markov processes.

A Crude Look at the Whole: The Science of Complex Systems in Business, Life, and Society
by John H. MillerImagine trying to understand a stained glass window by breaking it into pieces and examining it one shard at a time. While you could probably learn a lot about each piece, you would have no idea about what the entire picture looks like. This is reductionism--the idea that to understand the world we only need to study its pieces--and it is how most social scientists approach their work. In A Crude Look at the Whole, social scientist and economist John H. Miller shows why we need to start looking at whole pictures. For one thing, whether we are talking about stock markets, computer networks, or biological organisms, individual parts only make sense when we remember that they are part of larger wholes. And perhaps more importantly, those wholes can take on behaviors that are strikingly different from that of their pieces. Miller, a leading expert in the computational study of complex adaptive systems, reveals astounding global patterns linking the organization of otherwise radically different structures: It might seem crude, but a beehive’s temperature control system can help predict market fluctuations and a mammal’s heartbeat can help us understand the "heartbeat” of a city and adapt urban planning accordingly. From enduring racial segregation to sudden stock market disasters, once we start drawing links between complex systems, we can start solving what otherwise might be totally intractable problems. Thanks to this revolutionary perspective, we can finally transcend the limits of reductionism and discover crucial new ideas. Scientifically founded and beautifully written, A Crude Look at the Whole is a powerful exploration of the challenges that we face as a society. As it reveals, taking the crude look might be the only way to truly see.

It describes how to set up and analyse models of real-life phenomena that involve elements of chance. Motivation comes from everyday experiences of probability, such as that of a dice or cards, the idea of fairness in games of chance, and the random ways in which, say, birthdays are shared or particular events arise. Applications include branching processes, random walks, Markov chains, queues, renewal theory, and Brownian motion. This popular second edition textbook contains many worked examples and several chapters have been updated and expanded. Some mathematical knowledge is assumed. The reader should have the ability to work with unions, intersections and complements of sets; a good facility with calculus, including integration, sequences and series; and appreciation of the logical development of an argument. Probability Models is designed to aid students studying probability as part of an undergraduate course on mathematics or mathematics and statistics.
Reinventing Clinical Decision Support: Data Analytics, Artificial Intelligence, and Diagnostic Reasoning (HIMSS Book Series)
by Paul Cerrato John HalamkaThis book takes an in-depth look at the emerging technologies that are transforming the way clinicians manage patients, while at the same time emphasizing that the best practitioners use both artificial and human intelligence to make decisions. AI and machine learning are explored at length, with plain clinical English explanations of convolutional neural networks, back propagation, and digital image analysis. Real-world examples of how these tools are being employed are also discussed, including their value in diagnosing diabetic retinopathy, melanoma, breast cancer, cancer metastasis, and colorectal cancer, as well as in managing severe sepsis. With all the enthusiasm about AI and machine learning, it was also necessary to outline some of criticisms, obstacles, and limitations of these new tools. Among the criticisms discussed: the relative lack of hard scientific evidence supporting some of the latest algorithms and the so-called black box problem. A chapter on data analytics takes a deep dive into new ways to conduct subgroup analysis and how it’s forcing healthcare executives to rethink the way they apply the results of large clinical trials to everyday medical practice. This re-evaluation is slowly affecting the way diabetes, heart disease, hypertension, and cancer are treated. The research discussed also suggests that data analytics will impact emergency medicine, medication management, and healthcare costs. An examination of the diagnostic reasoning process itself looks at how diagnostic errors are measured, what technological and cognitive errors are to blame, and what solutions are most likely to improve the process. It explores Type 1 and Type 2 reasoning methods; cognitive mistakes like availability bias, affective bias, and anchoring; and potential solutions such as the Human Diagnosis Project. Finally, the book explores the role of systems biology and precision medicine in clinical decision support and provides several case studies of how next generation AI is transforming patient care.
