The mid-sized Second Canadian Edition of Human Sexuality in a World of Diversity is a briefer, but complete textbook that covers succinctly all the important topics required for today's human sexuality courses. With a research focus and thoroughly integrated Canadian material, it is 100 pages shorter than the comprehensive hardcover texts. This new edition, in an attractive softcover format, examines the psychology and science of sexuality, emphasizing diversity, critical thinking, responsible decision-making, and sexual health. Coverage is very current and includes new developments in the discipline and in Canadian society in areas such as drugs, technology, hormone replacement therapy, new contraceptives, using the Internet to meet sexual partners, sex education, and sexuality and disabilities.
