Acland looks back at the strange history of subliminal seduction: a theory first propagated in the late 1950s by marketing researcher James Vicary, who claimed that movie audiences bought more refreshments if advertising messages too quick to be noticed were inserted into movies. The study was soon proven false, but that hasnt kept the concept from having a long afterlife in the popular imagination.

Whether you are a seasoned Objective-C developer or new to the Xcode platform, Swift Essentials will provide you with all you need to know to get started with the language. Prior experience with iOS development is not necessary, but will be helpful to get the most out of the book.

Chimney Swifts, birds that nest and roost in chimneys, have been historically abundant in North America. But by the late 1980s, the number of swifts migrating to North America from the Amazon River Basin had declined. A growing number of people across North America are now constructing nesting towers and conducting Chimney Swift conservation projects in their own communities. With Chimney Swift Towers, concerned bird conservationists have a step-by-step guide to help them create more habitat for these beneficial, insect-eating birds. Chimney Swift experts Paul and Georgean Kyle give directions for building freestanding wooden towers, wooden kiosk towers, masonry towers, and other structures. Included are - design basics, - lists of materials needed, - useful diagrams and photographs, - and detailed instructions on site preparation, tower construction, installation, and maintenance. Anyone with basic woodworking or masonry skills and an interest in wildlife conservation will find this publication helpful. That includes do-it-yourselfers, homeowners involved in creating backyard habitat for wildlife, landscape and structural architects, park and wildscape managers, wildlife management area professionals, nature centers, garden centers, scout troops, and other civic organizations in search of community service projects.
