Differential Equations and Group Methods for Scientists and Engineers presents a basic introduction to the technically complex area of invariant one-parameter Lie group methods and their use in solving differential equations. The book features discussions on ordinary differential equations (first, second, and higher order) in addition to partial differential equations (linear and nonlinear). Each chapter contains worked examples with several problems at the end; answers to these problems and hints on how to solve them are found at the back of the book. Students and professionals in mathematics, science, and engineering will find this book indispensable for developing a fundamental understanding of how to use invariant one-parameter group methods to solve differential equations.

This volume brings together research on cyberbullying across contexts, age groups, and cultures to gain a fuller perspective of the prevalence and impact of electronic mistreatment on individual, group, and organizational outcomes. This is the first book to integrate research on cyberbullying across three contexts: schools, workplaces, and romantic relationships, providing a unique synthesis of lifespan contexts. For each context, the expert chapter authors bring together three different 'lenses': existing research on the predictors and outcomes of cyberbullying within that context; a cross-cultural review across national borders and cultural boundaries; and a developmental perspective that examines age-related differences in cyberbullying within that context. The book closes by drawing commonalities across these different contexts leading to a richer understanding of cyberbullying as a whole and some possible avenues for future research and practice. This is fascinating reading for researchers and upper-level students in social psychology, counseling, school psychology, industrial-organizational psychology, and developmental psychology, as well as educators and administrators.
