With the advent of computers that can handle symbolic manipulations, abstract algebra can now be applied. In this book David Joyner, Richard Kreminski, and Joann Turisco introduce a wide range of abstract algebra with relevant and interesting applications, from error-correcting codes to cryptography to the group theory of Rubik's cube. They cover basic topics such as the Euclidean algorithm, encryption, and permutations. Hamming codes and Reed-Solomon codes used on today's CDs are also discussed. The authors present examples as diverse as "Rotation," available on the Nokia 7160 cell phone, bell ringing, and the game of NIM. In place of the standard treatment of group theory, which emphasizes the classification of groups, the authors highlight examples and computations. Cyclic groups, the general linear group GL(n), and the symmetric groups are emphasized. With its clear writing style and wealth of examples, Applied Abstract Algebra will be welcomed by mathematicians, computer scientists, and students alike. Each chapter includes exercises in GAP (a free computer algebra system) and MAGMA (a noncommercial computer algebra system), which are especially helpful in giving students a grasp of practical examples.

Why do we see so little progress in diversifying faculty at America’s colleges, universities, and professional schools? This book explores this important question and provides steps for hastening faculty diversity. Drawing on her extensive consultant practice and expertise as well as research and scholarship from several fields, Dr. Moody provides practical and feasible ways to improve faculty recruitment, retention, and mentorship, especially of under-represented women in science-related fields and non-immigrant minorities in all fields. The second edition of Faculty Diversity offers new insights, strategies, and caveats to the current state of faculty diversity. This revised edition includes: New strategies to prevent unintended cognitive bias and errors that damage faculty recruitment and retention Expanded discussion on the importance of different cultural contexts, political, and historical experiences inhabited and inherited by non-immigrant faculty and students Increased testimonials and on-the-ground reflections from faculty, administrators, and leaders in higher education, with new attention to medical and other professional schools Updated Appendix with Discussion Scenarios and Practice Exercises useful to search and evaluation committees, department chairs, deans, faculty senates, and diversity councils Expanded chapter on mentoring that dispels myths about informal mentoring and underlines essential components for formal programs. Moody provides an essential, reliable, and eye-opening guide for colleges, medical, and other professional schools that are frustrated in their efforts to diversify their faculty.
