A completely revised edition, offering new design recipes for interactive programs and support for images as plain values, testing, event-driven programming, and even distributed programming. This introduction to programming places computer science at the core of a liberal arts education. Unlike other introductory books, it focuses on the program design process, presenting program design guidelines that show the reader how to analyze a problem statement, how to formulate concise goals, how to make up examples, how to develop an outline of the solution, how to finish the program, and how to test it. Because learning to design programs is about the study of principles and the acquisition of transferable skills, the text does not use an off-the-shelf industrial language but presents a tailor-made teaching language. For the same reason, it offers DrRacket, a programming environment for novices that supports playful, feedback-oriented learning. The environment grows with readers as they master the material in the book until it supports a full-fledged language for the whole spectrum of programming tasks. This second edition has been completely revised. While the book continues to teach a systematic approach to program design, the second edition introduces different design recipes for interactive programs with graphical interfaces and batch programs. It also enriches its design recipes for functions with numerous new hints. Finally, the teaching languages and their IDE now come with support for images as plain values, testing, event-driven programming, and even distributed programming.

One line straight down. One line to the right. One line to the left, then a circle. That was all—just three lines in a circle. This bold picture book tells the story of the peace symbol—designed in 1958 by a London activist protesting nuclear weapons—and how it inspired people all over the world. Depicting the symbol's travels from peace marches and liberation movements to the end of apartheid and the fall of the Berlin Wall, Three Lines in a Circle offers a message of inspiration to today's children and adults who are working to create social change. An author’s note provides historical background and a time line of late twentieth-century peace movements.

A 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.

Prioritizing Academic Programs and Services REVISED AND UPDATED Increasing economic concerns make the new edition of this best-selling classic an invaluable resource for those who want and need to implement a proven step-by-step approach to reallocating resources in tough times. Thoroughly revised and updated, Prioritizing Academic Programs and Services includes new recommendations from the field, communication strategies for more successful campus implementation, a new section on the sources of hidden costs, and a Prioritization Process and Implementation workbook designed to help administrators avoid costly mistakes. This book includes access to additional content online, including models for prioritization from a variety of campuses. Based on the author's extensive consulting experience, this necessary and timely resource offers the best advice for addressing the current economic concerns affecting most colleges and universities. Praise for Prioritizing Academic Programs and Services "For more than a decade, higher education leaders have turned to Dickeson's practical guide to academic program assessment. These newly expanded approaches are just in time for today's competitive environment." SUZANNE SHIPLEY, president, Shepherd University "Dickeson provides a compelling rationale for program prioritization as well as a practical planning structure that promotes alignment between programs, resources, and university mission. Presidents and provosts can use his approach to frame campus discussions around the future of the institution and away from legacy programs whose time has passed." KYLE R. CARTER, provost and senior vice chancellor, Western Carolina University "Dickeson's approach ensures that critical decisions regarding academic programs and resource allocation are aligned with strategic goals and institutional mission. As one of the early adopters of the process that he proposes, I am convinced that it is a powerful and practical tool for any college or university committed to remaining focused, resilient, vital, and relevant in a dynamic and increasingly challenging environment." DAVID MAXWELL, president, Drake University
