Robert L CrooksThe integration of psychological, social and biological components of human sexuality in this text is facilitated by the authors' combined academic and professional backgrounds. With sadness we dedicate this 14th edition to Dr. Robert Crooks, who pased away at the end of the last revision. Dr. Crooks had a Ph.D. in Psychology. In addition to graduate training that stressed Clinical and Physiological Psychology, he had a considerable background in Sociology. His involvement with teaching human sexuality classes at the university, college and medical school levels spanned over two decades. Dr. Crooks and his wife, Sami Tucker, were involved in the establishment and implementation of HIV/AIDS intervention programs in two areas of Kenya. For more than a decade, their work with these projects included designing a research strategy for assessing behavior change, developing a peer educator-based educational strategy and conducting training sessions for Kenyan peer educator staff.
