Sex and World Peace (9780231131827): Valerie M. Hudson, Bonnie Ballif-Spanvill, Mary Caprioli, Chad F. Emmett
I have not yet had the opportunity to read this book but feel that it touches on some of the core issues in geography today: gender, culture and political stability (plus, it's just a great title). The authors of Sex and World Peace explore the relationships between cultural norms regarding gender and political stability and war. They show that security for women translates to security for the state. According to the authors, they "compare micro-level gender violence and macro-level state peacefulness in global settings...[and] mount a solid campaign against women's systemic insecurity, which effectively unravels the security of all."
Written by geography, political science and psychology professors, Sex and World Peace is the synthesis of years of research produced as a part of the WomanStats project. For more about this ongoing project and the great database which they have produced (loaded with potential for student projects) see: http://womanstats.org
