This volume presents the proceedings of a conference on Harmonic Analysis and Number Theory held at McGill University (Montreal) in April 1996. The papers are dedicated to the memory of Carl Herz, who had deep interests in both harmonic analysis and number theory. These two disciplines have a symbiotic relationship that is reflected in the papers in this book.

The principal aim of this book is to give an introduction to harmonic analysis and the theory of unitary representations of Lie groups. The second edition has been brought up to date with a number of textual changes in each of the five chapters, a new appendix on Fatou's theorem has been added in connection with the limits of discrete series, and the bibliography has been tripled in length.

In recent years there has been a tremendous growth in psychology as a field of study and in the number of students of clinical psychology in particular. The latter is partly due to the proliferation of professional schools of psychology that are devoted to practitioner-oriented degrees, rather than the traditional research-oriented course of study. Whatever school students emerge from, however, they are obliged to demonstrate proficiency in providing clinical services. This multi-volume handbook, is devoted to describing the core competency areas in providing psychological services which is relevant to practitioners as well as clinical researchers. As such, it covers assessment and conceptualization of cases, the application of evidence-based methods, supervision, consultation, cross-cultural factors, and ethics. The Handbook comprises three volumes with contributions by experts in each area. The goal is to provide detailed descriptions of competence levels and describe the developmental trajectory required to reach the highest of these levels. Each chapter in Volume I will follow a similar format including an overview, basic competencies, and expert competencies. This will facilitate easy comparison across chapters. All will be illustrated with case examples. Subsequent volumes will have a similarly structured format that will include maintenance factors, mechanisms of change, evidence-based treatment approaches, and a focus on the transition from basic skills to expert functioning. It is expected that the systematic presentation of skills will provide a gold standard against which to measure individual performance and in this regard will be valuable to students, instructors, and credentialing bodies.

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.
