'Traditionally, texts on mathematical modeling rarely select topics from social sciences, and this interesting book is a welcome addition to existing literature. It appeals to students and researchers in social and behavioral sciences, natural sciences, engineering, mathematics, as well as to anyone curious enough to patiently go through clearly explained and not very difficult mathematical passages in order to understand the chemistry of marital interactions, residential segregation and genocide, intelligence theories or approaches to learning. Believe me; your efforts will be generously rewarded!' Zentralblatt MATH
