Proven strategies for harnessing the power of social media to drive social change Many books teach the mechanics of using Facebook, Twitter, and YouTube to compete in business. But no book addresses how to harness the incredible power of social media to make a difference. The Dragonfly Effect shows you how to tap social media and consumer psychological insights to achieve a single, concrete goal. Named for the only insect that is able to move in any direction when its four wings are working in concert, this book Reveals the four "wings" of the Dragonfly Effect-and how they work together to produce colossal results Features original case studies of global organizations like the Gap, Starbucks, Kiva, Nike, eBay, Facebook; and start-ups like Groupon and COOKPAD, showing how they achieve social good and customer loyalty Leverage the power of design thinking and psychological research with practical strategies Reveals how everyday people achieve unprecedented results-whether finding an almost impossible bone marrow match for a friend, raising millions for cancer research, or electing the current president of the United States The Dragonfly Effect shows that you don't need money or power to inspire seismic change.

Dragonfly Genera of the New World is a beautifully illustrated and comprehensive guide to the taxonomy and ecology of dragonflies in North, Middle, and South America. A reference of the highest quality, this book reveals the striking beauty and complexity of this diverse order. Although Odonata-dragonflies and damselflies-are among the most studied groups of insects, until now there has been no reliable means to identify the New World genera of either group. This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia. For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.
